Description
- 1. Field of the Invention:
- The present invention relates to a stand with infrared emission, and particularly to a stand for placing a personal digital assistant (PDA), with which a gyratory arm can be rotated adjustably to allow an infrared emitting device aligning with an infrared receiver of the PDA for facilitating data receipt.
- 2. Description of Related Art:
- Due to the development of technology changing rapidly, our lives become getting more complicated than before. A matter in a company such as making sure the time of a conference, a briefing, arranging the visit time of client and etc. and a personal business such as a birthday of a family member, an anniversary and etc., which includes routine works and accidental events, have regulated our daily life schedule. In order to record the preceding schedules or dates, a conventional way frequently used is recorded in a memorandum book as a handy reminder. However, it is often careless to make a record in the memorandum book.
- Taking the advantage of electronic technology developing rigorously, a so-called personal digital assistant (abbreviated as PDA hereinafter) is rose at the right time. The PDA, which is a light and small electronic device, has been developed to provide a function of multimedia recently.
- According to two primary operation systems, Plam OS and Pocket PC, in the field of PDA, handwriting is used as data input and the input data is treated by recognition software before being stored in the memory. Owing to the speed of handwriting being much slower than keyboard input, it is the reason why the handwriting mode is undesirable by the user. Therefore, the manufactures have developed a keyboard especially for the PDA and the specifically designed keyboard has taken the advantage of the PDA with the Plam OS or the Pocket PC operation system having the infrared (IR) being used as a transmission device. Hence, an infrared emitting device is provided next to the keyboard to send signals out while the keyboard is operated and a infrared receiver built in the PDA can receive the signals instead of the inconvenient handwriting mode.
- But, the deficiency of the keyboard with an infrared emitting device is in that the infrared receivers mounted in different brand PDAs are disposed at inconsistent locations on the outer casing thereof such as the left lateral wall, the right lateral wall or the top thereof. In order to perform the signal transmission, the emitting device has to be disposed corresponding to the receiver and the display screen is placed toward a lateral side or even inversely placed. The preceding situations result in the input characters or symbols becoming laterally or inversely oriented such that it is hard to be sighted with eyes. A basic problem of the preceding deficiency is the conventional infrared emitting device being stationary so that it is unable to comply with different positioned infrared receivers on the PDA.
- The crux of the present invention resides in that a stand with infrared emission, which is connected to a related circuit of a keyboard, includes a pivot seat, a base, a support plate and a gyratory arm. The pivot seat is a joining part with an end thereof being connected to the keyboard and the other end thereof having a first pivot device. The base at the lower end thereof is connected to the pivot device. The support plate has the lower side thereof integrally connecting with the upper end of the base and the upper side thereof being provided with a connection part. The gyratory arm at the lower end thereof joining the connection part of the support plate and the upper end thereof is provided with an abrupt emission seat. An infrared emitter is disposed in the emission seat and electrically connected to the keyboard. A PDA can be placed on both the base and the support plate with the gyratory arm being adjustably rotated such that the emission seat can align with an infrared receiver so as to facilitate data transmission.
- The present invention can be more fully understood by reference to the following description and accompanying drawings, in which:
- FIG. 1 is a plan view of a stand with infrared emission according to the present invention associated with a keyboard;

Thesupport plate 3 at the upper corner thereof has alower plate recess 32 and a locatinghole 33 and at the lower portion thereof has a hollow-out 34 corresponding to theemission seat 42 of thegyratory arm 4 for receiving theemission seat 42 while thegyratory arm 4 is taken in. Besides, the facial side of thesupport plate 3 has two oppositeelongated nests 35 corresponding to the twoelongated pad recesses 212 for locating the twoanti-slip pads 36 so that it is not possible for the PDA to slip during being placed on thesupport plate 3. Further, the support plate at the lower side thereof has arear baffle 37 against the back side of thebase 2 at the top edge thereof such that thesupport plate 3 can be retained and define the maximum opening angle. - The
gyratory arm 4 is a lever with aprotrusion 41 at the lower end thereof to fit with the locatinghole 33 so that thegyratory arm 4 can be rotated with respect to thesupport plate 3. The other end of thegyratory arm 4 has anabrupt emission seat 42 with aninfrared emitting device 43 therein and theinfrared emitting device 43 connects with the keyboard A via a signal wire passing the precedingwire passage 132. - FIG. 4 shows the stand with infrared emission of the present invention has been assembled already. While in use, the only thing has to be done is to place the PDA on the
base 2 and thesupport plate 3 under a condition of theemission seat 42 aligning with the infrared receiver in the PDA. Meanwhile, the keyboard is operated to allow the signal passing through the signal lines such that the signal can be emitted by theinfrared emitting device 43 and received by the receiver in the emission seat. In this way, the purpose for accurate emission and receiving can be achieved desirably. - In case of taking in the stand of the present invention, referring to FIG. 5, first of all, the
gyratory arm 4 is rotated toward the hollow-out 34 to locate theemission seat 42 in the hollow-out 34. Then, thesupport plate 3 is turned toward thebase 2 and received in a space enclosed by theedge projections 22 on thebase plate 21 such that theabrupt emission seat 42 can be disposed in thereceiving hole 211 and theanti-slip pads 36 are received in thepad recesses 212 to allow the rear side of thesupport plate 3 keeping flush with the upper faces of theedge projections 22. At this moment, the Ushaped frame 224 is received in the twoframe grooves 223 and thebase 2 is flattened with thepivot seat 1 for the entire stand being inserted into the keyboard. - It is appreciated that the stand with infrared emission of the present invention can be stretched or folded to meet the requirement of being operated flexibly due to it being possible to be turned and bent. Further, the emission seat in the present invention can obtain an optimum emitting angle via the gyratory being rotated adjustably to comply with different infrared receivers provided in different brands of PDA for performing more accurate key-in job. Meanwhile, the present invention makes the display screen of the PDA keep a best visional projection angle to fulfill the criteria of human engineering. Furthermore, the U shaped frame disposed under the base disclosed in the stand of the present invention being capable of regulating the angle of elevation of the entire stand is a pretty delicate design. Meanwhile, the stand of the present invention can be received in a keyboard completely after being turned and folded so as not to occupy the original space of the original keyboard.
