Description
The present invention relates to an electronic print board provided with an endless writiny medium.
A prior art electronic print board is disclosed in Canadian patent No. 1,211,495 issued September 16, 1986.
An electronic print boaxd is used in conferences, explanation meetings, and preliminary meetings, etc.
The electronic print board allows various results produced during the progress of a conference, the contents of a preliminary arrangement, or information such as symbols and figures and the like, to be written thereon, and displays them for participants.
These items of information are written, on a large-sized writing medium provided with a scene movable by a roller, by means of a writing tool such as an aqueous felt pen. In addition, these items of information can be scaled down onto a recordlng paper, copied onto a required number of sheets, and distributed to participants. There is known a writing medium used for such an electronic print board, which is endlessly formed and movable in circulation by the rotation of a roller. However, a writing medium used for such an electronic print board is easily deterio-rated in its surface processing upon its use for a prescribedperiod of time because of its special processing. accordingly, it has a drawback that it becomes impossible to be used.
It is an object of the present invention to provide an improved electronic print board.
Another object of the present invention is to provide an electronic print board provided with a writing medium easy to be 8~9 replaced.

The writing medium 1 is obtained by putting a fluorine film on, e.g., a ~ilk-white opaque whitened polyester film and joining them. For the fluorine film, it is possible to write a picture image thereon by an aqueous felt pen, eta., and to easily erase it therefrom with cloth, etc. The writing medium 1 is the same as or slightly narrower in its width than the endless belt 2 and sized in length to be equal to the longitudinal length of the endless belt 2.
With this construction, any picture image such as a character, a numeral and a figure, etc., is written on the writing medium 1 by a writing tool. When scaling down the written picture image and recording it on recording paper 12, rotation of the driving roller 4 by the motor 6 allows the movement of the endless belt 2 toward the fluorescent lamp 7, causing the writing medium 1 mounted on the endless belt 2 to move with the belt.
The fluorescent lamp 7 successively illuminates the approaching writing medium at a prescribed position, and the reflected ray beam of light is projected onto the readout sensor 10 via the lens 9, allowing the image to be read out. The readout image is recorded on the recording paper 12 through the recording device 11, and thereaEter the paper 12 sent out from the device.
The feature OL the embodiment is described below.
When the writing medium 1 us used as described above has served its time due to its use over a long period of time, or when subjected to any external force and destroyed, it must be replaced with a new one. In that case, it is possible to remove the writing medium t from the endless belt 2 as shown in Figure 3 by ,~, J"
separating off the fixing device 3b on one end of the writing medium 1 from the fixing device 3a of the endless belt 2, and after moving the belt 2 and turnins it one revolution, separating off the fixing device 3b on the other end of the writing medium 1.
fter removing the writing medium 1 from the endless belt 2 in such a way, by fixing the fixing device 3b on one end of a new writing medium 1 on the fixing device 3a of the endless belt
