Abstract
Description
- The present invention relates to a stamp device for forming an image on a thermal stencil paper and transferring the image to a recording paper and, more particularly, to a stamp device enabling an operator to confirm the image to be formed on the thermal stencil paper.
- A rubber stamp is conventionally used to print various representations such as an address and name of a person or company. Such a rubber stamp is useful and convenient in the case of repeatedly printing the same characters. Another type of printing device is a depression type stamp device employing a thermal stencil paper. This device will now be described with reference to the drawings.
- Fig. 9 is a perspective view of a previously proposed
stamp device 1. Thestamp device 1 includes akeyboard 10, abody 11, astamp 12, and a liquid crystal display (which will be hereinafter referred simply to as a "display") 14 having the predetermined number of display columns. Thekeyboard 10 includes acharacter key 42 for inputting characters such as Japanese "kana" character and alphabet, and also includes various function keys such as a stamp original creating key. - As shown in Fig. 8 which is a cross section taken along the line F-F in Fig. 9, the
body 11 is constituted of a stencilpaper holding section 15, an original creatingsection 16, astamp holding section 17, and acontrol section 18. Thestamp 12 is constituted of agrip 13, astamp body 28, aspring 29, and anink pad 30. The original creatingsection 16 includes athermal head 19 as heating means. Thethermal head 19 is pressed against aplaten roller 20. A thermal stencil paper (which will be hereinafter referred simply to as a "stencil paper") 24 is drawn by a stencilpaper drawing roller 21, and is fed by stencil paperfeeding roller pairs 22 to between thethermal head 19 and theplaten roller 20. - After the
stencil paper 24 is thermally perforated by thethermal head 19, it is further fed by the stencil paperfeeding roller pairs 22 and stencilpaper feeding rollers 23 to under thestamp 12. Thestamp body 28 of thestamp 12 is secured to a supporting member (not shown) with agap 27 defined between theink pad 30 and the stencilpaper feeding rollers 23 in thestamp holding section 17. The thermally perforatedstencil paper 24 is fed by the stencil paperfeeding roller pairs 22 and the stencilpaper feeding rollers 23 by a predetermined amount so as to come to just under theink pad 30. - The
stencil paper 24 is formed by bonding a thermoplastic film to a porous carrier. Thestencil paper 24 is used under the condition where the thermoplastic film side is adapted to contact thethermal head 19. As shown in Figs. 10 and 11, aframe 25 is bonded onto thestencil paper 24. - The
thermal head 19 has a head body provided with a heat generating element array. The heat generating element array consists of a plurality of heat generating elements, e.g., 96 heat generating elements are arranged in line in thestamp device 1. These heat generating elements are arranged adjacent to each other in a direction perpendicular to a feeding direction of thestencil paper 24. The heat generating element array is driven at a predetermined timing in accordance with feed of thestencil paper 24 to thereby thermally perforate thestencil paper 24 according to data input from thekeyboard 10. - A control system of the
stamp device 1 will be described with reference to the block diagram shown in Fig. 12. Thekeyboard 10 is connected to aninput interface 58 in amicrocomputer 56. Theinput interface 58 is connected through abus line 60 to aCPU 62, aROM 64, aRAM 66, a character generator (CG-ROM) 68 for thermal perforation of thestencil paper 24, a character generator (CG-ROM) 69 for display, and anoutput interface 70. - The
ROM 64 includes aprogram memory 71 previously storing a program for controlling the whole operation of thestamp device 1 and adictionary memory 72 to be used for kana/kanji conversion where Japanese "kana" characters are converted into Chinese "kanji" characters or the like. TheRAM 66 includes aninput buffer 73 for storing data input from thekeyboard 10, athermal perforation buffer 74 and ashift register 75 for storing data for thermal perforation of thestencil paper 24, and other necessary counters and registers. - The CG-
ROM 68 serves to generate dot patterns according to code data of characters input, and the CG-ROM 69 serves to generate dot patterns to be displayed on thedisplay 14. - A
head driving circuit 76, amotor driving circuit 77 and adisplay driving circuit 78 are connected to theoutput interface 70. Thethermal head 19,paper feeding motors 32 and thedisplay 14 are connected to thecircuits - The operation of creating a stamp original by the
stamp device 1 will now be described with reference to the flowchart shown in Fig. 13. When power is applied to thestamp device 1, the buffers, registers, etc. in theRAM 66 are initialized, and the others are also initialized in step S1 (which will be hereinafter referred simply to as "S1", and the other steps will also similarly referred). Then, a string of characters is input from thekeyboard 10 with the characters displayed on thedisplay 14. That is, data for therma! perforation is input from thecharacter key 42, and it is stored into theinput buffer 73 in S2, S3 and S4. At the same time, in S5, the characters corresponding to the thermal perforation data are displayed on thedisplay 14 through the CG-ROM 69. - When the stamp original creating key is depressed, S7 is executed after S2 and S6, in which the dot patterns generated in the CG-
ROM 68 according to the code data input are developed in thethermal perforation buffer 74. Then, the program proceeds to S8 in which the dot patterns developed in thethermal perforation buffer 74 are transferred by every row of dots to theshift register 75 to thermally perforate thestencil paper 24 in accordance with the row of dots. In S9, it is determined whether or not all the thermal perforation data have been output to thestencil paper 24, and the steps of S8 and S9 are repeated to finally obtain the result of thermal perforation constituted of 96 dots over the length of the heat generating element array. At this time, the thermally perforatedstencil paper 24 is fed by the stencil paperfeeding roller pairs 22 and the stencilpaper feeding rollers 23 in a direction D shown in Fig. 8. - When the
grip 13 of thestamp 12 is depressed toward thestencil paper 24 against thespring 29, theink pad 30 comes into contact with thestencil paper 24. Owing to the viscosity of ink impregnated in theink pad 30, thestencil paper 24 adheres to theink pad 30. Then, thestamp 12 is pulled out of thestamp holding section 17 of thebody 11 of thestamp device 1 by holding thegrip 13. Thereafter, thegrip 13 of thestamp 12 is depressed toward arecording paper 35 in a direction H shown in Fig. 14, and the ink impregnated in theink pad 30 is supplied to thestencil paper 24. As a result, a part of the ink at a thermally perforated portion only of thestencil paper 24 is allowed to reach therecording paper 35, thus forming an image on therecording paper 35 as shown in Fig. 15. - However, resolution of the liquid crystal display is greatly lower than that of the thermal head. Accordingly, when an operator intends to confirm a stamp image formed after inputting data from the keyboard, the stamp image cannot be clearly confirmed on the liquid crystal display. So, the operator is obliged to actually print the input data as a sample or view the perforation image on the stencil paper attached to the stamp. If the stamp image is not satisfactory in the sample or as viewed in the perforation, the stencil paper is obliged to be wasted.
- An object of the present invention is to provide a stamp device which enables the stamp image to be confirmed without wasting the stencil paper.
- To achieve the above and other objects, a stamp device is provided including storing means for storing image data representing an image, first heating means for generating heat based on the image data stored by the storing means, stencil paper feeding means for feeding the first heating means with a thermal stencil paper which is thermally perforated by heat generated by the first heating means, and recording sheet feeding means for feeding the first heating means with a thermal recording sheet which is visibly recorded by heat generated by the first heating means, wherein the thermal recording sheet is used to confirm the image to be perforated on the thermal stencil paper before thermally perforating the thermal stencil paper.
- In the stamp device according to the present invention, image data representing an image such as an arbitrary figure or string of characters are stored in the storing means. Then, the thermal recording sheet is fed to the first heating means by the recording sheet feeding means. A dot image corresponding to the stored image data is thermally formed on the thermal recording sheet by the first heating means. After confirming the image thus recorded on the thermal recording sheet, the thermal stencil paper is fed to the first heating means by the stencil paper feeding means. The thermal stencil paper is thermally perforated by the first heating means to form the dot image corresponding to the stored image data. Then, the thermal stencil paper thus perforated to have the image is attached to a stamp. Then, the stamp is depressed on a recording paper to transfer the image from the thermal stencil paper to the recording paper.

- First, there will be described a reversible thermal recording sheet (which will be hereinafter referred simply to as a "reversible sheet") 101 with reference to Figs. 3, 4 and 5. Such a reversible sheet is known as a thermo-chromic in Japanese Patent Laid-open No. Sho 63-39377, for example. Referring to Fig. 3 which is a sectional view of the
reversible sheet 101, arecording layer 103 is formed on atransparent polyester film 102, and anovercoat layer 105 is formed on therecording layer 103, so as to protect the same. Therecording layer 103 is constituted of resin and organic low-molecular substance 104 dispersed in the resin. - Fig. 4 shows a transparent condition and a white opaque condition of the
reversible sheet 101. In the transparent condition shown on the left-hand side in Fig. 4, each particle of the organic low-molecular substance 104 in thereversible sheet 101 is formed as a relatively large monocrystal, so that light incident into thereversible sheet 101 passes an interface of the crystal few times and is transmitted through therecording layer 101 without scattering. Therefore, the recoding layer looks transparent as a whole. On the other hand, in the white opaque condition shown on the right-hand side in Fig. 4, each particle of the organic low-molecular substance 104 in thereversible sheet 101 is formed as a polycrystal, so that light incident into thereversible sheet 101 is refracted at the interface of the crystal many times and is scattered. Therefore, the recording layer, 101 looks white opaque as a whole. - Fig. 5 shows a heat reversible characteristic of the
reversible sheet 101. When thereversible sheet 101 in the white opaque condition at a room temperature is heated, a transmittance of thereversible sheet 101 starts to increase at a temperature A and reaches a maximum at a temperature B. Thereafter, even when thereversible sheet 101 is cooled to the room temperature, the transparent condition is maintained. This is due to the fact that the organic low-molecular substance 104 changes from the white opaque condition of the polycrystal to a semi-molten condition during the increase from the temperature A to the temperature B, and the crystal grows to become the transparent condition of the monocrystal upon cooling from the temperature B to the room temperature. - Thereafter, when the
reversible sheet 101 in the transparent condition is heated again to a temperature D or higher, an intermediate condition between the maximum transparent condition and the maximum white opaque condition is obtained. When thereversible sheet 101 in the intermediate condition is cooled to the room temperature, the initial white opaque condition is restored. This is due to the fact that the organic low-molecular substance 104 is molten at the temperature D or higher, and the polycrystal is deposited during cooling down to the room temperature. The temperatures A, B and D are preferably set to about 50 degrees, about 56-68 degrees and about 72 degrees, respectively. In this preferred embodiment, thereversible sheet 101 is heated by athermal head 19 to record an image. The transparent condition and the white opaque condition for every picture element of the image can be set by changing energy to be applied to the picture element which depends on a resolution of thethermal head 19. - Referring back to Fig. 3, a
colored layer 106 is located under thetransparent polyester film 102, so as to intensify a contrast of the image recorded on thereversible sheet 101. That is, thecolored layer 106 functions to make a transparent portion of thereversible sheet 101 contrast with a white opaque portion of thereversible sheet 101. For example, in the case where thecolored layer 106 is black and where the image is formed by the transparent portion with the white opaque portion left as the background, the image looks black on the white background as viewed from the upper side. Conversely, the image may be formed by the white opaque portion with the transparent portion left as the background. Further, also in the case of changing the color of thecolored layer 106 into red, blue or green, the same effect can be obtained. - Referring to Figs. 1 and 2, there is shown a
stamp device 80 employing the above-mentionedreversible sheet 101 according to the preferred embodiment. - Fig. 2 is a perspective view of the
stamp device 80, and Fig. 1 is a cross section taken along the line E-E in Fig. 2. It is to be noted that the same parts as those described in the background relating to the parent application and shown in Figs. 8-15 are denoted by the same reference numerals and the explanation thereof will be omitted hereinafter. - As shown in Fig. 2, the
stamp device 80 includes akeyboard 10, abody 82, astamp 12 and adisplay 14. As shown in Fig. 1, thebody 82 is constituted of a stencilpaper holding section 15a, a reversiblesheet holding section 15b, an original creatingsection 16, astamp holding section 17, acontrol section 18 and aheating roller section 84. The stencilpaper holding section 15a and the reversiblesheet holding section 15b are provided with a stencilpaper drawing roller 21a and a reversiblesheet drawing roller 21b, respectively. Thestencil paper 24 and thereversible sheet 101 are adapted to be drawn by the stencilpaper drawing roller 21a and the reversiblesheet drawing roller 21b, respectively. Thereafter, thestencil paper 24 and thereversible sheet 101 thus drawn are adapted to be fed by stencil paper feeding roller pairs 22 and be heated by thethermal head 19. Thereafter, they are adapted to be further fed by stencilpaper feeding rollers 23 in a direction D shown in Fig. 1. At the time thestencil paper 24 comes to a position just under anink pad 30, the feeding of thestencil paper 24 is stopped. On the other hand, thereversible sheet 101 after being heated by thethermal head 19 passes through thestamp holding section 17, and is further fed by reversiblesheet feeding rollers 91 to be discharged from a discharge opening 92 formed on a side surface of thebody 82. - The construction of the parts other than the
heating roller section 84 is substantially the same as that in the parent application described in the background and shown in Figs. 8-15, and so the detailed explanation of the same parts will be omitted hereinafter. Theheating roller section 84 is constituted of sheet guides 86 and 87 for smoothing the feeding of thereversible sheet 101 and aheating roller pair 90 having aheating device 88 in one roller at a central portion thereof. - A control system of the
stamp device 80 will be described with reference to the block diagram shown in Fig. 6. Thekeyboard 10 is connected to aninput interface 58 in amicrocomputer 56. Theinput interface 58 is connected through abus line 60 to aCPU 62, aROM 64, aRAM 66, a character generator (CG-ROM) 68 for thermal perforation of thestencil paper 24, a character generator (CG-ROM) 69 for display, and anoutput interface 98. - The
ROM 64 includes aprogram memory 71 previously storing a program for controlling the whole operation of thestamp device 80 and adictionary memory 72 to be used for kana/kanji conversion or the like. TheRAM 66 includes aninput buffer 73 for storing data input from thekeyboard 10, athermal perforation buffer 74 and ashift register 75 for storing data for thermal perforation of thestencil paper 24, and other necessary counters and registers. - The CG-
ROM 68 serves to generate dot patterns according to code data of characters input, and the CG-ROM 69 serves to generate dot patterns to be displayed on thedisplay 14. - A
head driving circuit 76, amotor driving circuit 77, adisplay driving circuit 78, a heatingroller driving circuit 97 and a heatingdevice driving circuit 96 are connected to theoutput interface 98. Thethermal head 19,paper feeding motors 32, thedisplay 14, theheating roller pair 90 and theheating device 88 are connected to thecircuits paper feeding motors 32 are so provided as to correspond to the stencilpaper drawing roller 21a, the reversiblesheet drawing roller 21b, the stencil paper feeding roller pairs 22, the stencilpaper feeding rollers 23 and the reversiblesheet feeding rollers 91. - The operation of creating a stamp original by the
stamp device 80 will now be described with reference to the flowchart shown in Figs. 7A and 7B. - When power is applied to the
stamp device 80, the buffers, registers, etc. in theRAM 66 are initialized, and the others are also initialized in step S1 (which will be hereinafter referred simply to as "S1", and the other steps will also similarly referred). Then, a string of characters is input from thekeyboard 10 with the characters displayed on thedisplay 14. That is, data for thermal perforation is input from thecharacter key 42, and it is stored into theinput buffer 73 in S2, S3 and S4. At the same time, in S5, the characters corresponding to the thermal perforation data are displayed on thedisplay 14 through the CG-ROM 69. - When a confirming key is depressed, so as to confirm the above edited image by utilizing the
reversible sheet 101, thereversible sheet 101 stored in the reversiblesheet holding section 15b is drawn by the reversiblesheet drawing roller 21b, and then, is fed by the stencil paper feeding roller pairs 22. At the same time, S31 is executed after S2 and S30, in which the dot patterns generated in the CG-ROM 68 according to the code data input are developed in thethermal perforation buffer 74. - Then, the program proceeds to S32 in which the dot patterns developed in the
thermal perforation buffer 74 are transferred by every row of dots to theshift register 75 to thermally record the row of dots on thereversible sheet 101. In S33, it is determined whether or not all the data have been recorded on thereversible sheet 101, and the steps of S32 and S33 are repeated to finally obtain the result of thermal recording constituted of 96 dots over the length of the heat generating element array. At this time, the thermally recordedreversible sheet 101 is fed by the stencil paper feeding roller pairs 22 and the stencilpaper feeding rollers 23 in a direction D shown in Fig. 1. After passing through thestamp holding section 17, thereversible sheet 101 is further fed and discharged from the discharge opening 92 to the outside of thestamp device 80 by the reversiblesheet feeding rollers 91. In the above operation, thereversible sheet 101 is vertically oriented so that therecording layer 103 side of thereversible sheet 101 may contact thethermal head 19. - Thereafter, if the image thermally recorded on the
reversible sheet 101 discharged from the discharge opening 92 is satisfactory, thestencil paper 24 as the original for printing is created. That is, when the original creating key is depressed, the stencilpaper drawing roller 21a is driven to draw thestencil paper 24 from the stencilpaper holding section 15a, and thestencil paper 24 is fed by the stencil paper feeding roller pairs 22. The subsequent operation is the same as that described in the background with respect to the parent application and shown in Figs. 8-15, and so the explanation thereof will be omitted hereinafter. - If the image thermally recorded on the
reversible sheet 101 is unsatisfactory, the image is erased in the following manner. That is, thereversible sheet 101 is supplied to thesheet guide 86. In this condition, when an erasing key is depressed (S12), the program proceeds through S2 and S12 to S13, in which theheating roller pair 90 starts to be rotated (S13), and theheating device 88 is heated (S14). Thereversible sheet 101 is fed by theheating roller pair 90 heated to the temperature D or higher, and passes through theheating roller pair 90. As a result, the image thermally recorded on thereversible sheet 101 is thermally erased owing to the above-mentioned principle (S15). Thereversible sheet 101 in which the image previously recorded has been erased is discharged to the reversiblesheet holding section 15b. Then, theheating device 88 is turned off (S16), and theheating roller pair 90 stops rotating (S17). In the above operation, thereversible sheet 101 is vertically oriented so that therecording layer 103 side of thereversible sheet 101 may contact the roller of theheating roller pair 90 in which theheating device 88 is provided, that is, the lower roller as viewed in Fig. 1. - Then, the data is edited again by using the
keyboard 10 and is similarly thermally recorded on thereversible sheet 101. This operation is repeated many times until a satisfactory stamp image is obtained. Thereversible sheet 101 is durable and withstands frequently repeated thermal recording and erasing, so that the stamp image can be surely confirmed before carrying out the thermal perforation of thestencil paper 24, and thestencil paper 24 can be effectively used without waste. - Although the heat generating element array is constituted of 96 heat generating elements in the above preferred embodiment, the number of the heat generating elements may be arbitrarily changed.
- In the case where different characters are intended to be printed after the above-mentioned printing operation, the
stencil paper 24 attached to theink pad 30 of thestamp 12 is peeled off, and thestamp 12 is then set in thestamp holding section 17 of thebody 82 of thestamp device 80. Thereafter, a new stamp original is created in the same manner as the above. Further, thestencil paper 24 after printing may be preserved for the purpose of reuse at any time. Accordingly, it is unnecessary to re-create a new original having the same stamp image as that of thestencil paper 24 previously created, thus improving the economy of the system. - Further, although the
keyboard 10 of thestamp device 80 is employed as the inputting means in the above preferred embodiment, data such as characters or marks may be input from a personal computer or the like to a receiving terminal (not shown) of thestamp device 80. Also in this case, a stamp image may be formed in the same procedure as the above. - Further, although the
heating roller pair 90 is used to erase the image thermally recorded on thereversible sheet 101, thethermal head 19 may be used to erase the image so that the energy to be applied to thethermal head 19 is suitably changed. - Further, a conventional thermal recording sheet on which a non-erasable image is recorded by heat may be used instead of the reversible sheet. Conventional thermal recording sheets are cheaper than stencil paper, and therefore the cost of using conventional thermal recording sheets in the device is much lower than using stencil paper.
- As is apparent from the above description, according to the stamp device of the present invention, an original for printing can be simply created by inputting data such as characters or figures intended to be printed and thermally perforating the thermal stencil paper. Further, the thermal recording on the reversible thermal recording sheet for confirmation of a stamp image and the thermal perforation through the thermal stencil paper for creation of a stamp original can be carried out by using the single thermal head. Further, the data previously recorded on the reversible thermal recording sheet can be erased by using the heating roller to carry out frequently repeated thermal recording and erasing of data on the recording sheet, thus decreasing a cost for the recording sheet, avoiding wasteful use of the thermal stencil paper, and decreasing cost for the stamp device.
- While advantageous embodiments have been chosen to illustrate the invention, it will be understood by those skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention as defined in the appended claims.
