Abstract

PROBLEM TO BE SOLVED: To provide a sheet for an electronic blackboard apparatus for naturally correcting once generated winding nature by scarcely generating the nature. SOLUTION: This sheet comprises a UV-coated polyester film 7, another material 9, and adhesive material 8 for adhering the material 9 to a rear surface of the film 7. The material 9 is formed to scarcely generate winding nature at a writing sheet 2 and to correct the nature at the time of using even when the sheet 2 is slightly generated with the nature, and used with material such as sponge, felt, cork sheet, plastic sheet, vinyl chloride corrugated fiberboard, cloth, urethane or CR rubber.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic blackboard device sheet used as a writing medium for an electronic blackboard device.

[0002]

2. Description of the Related Art Conventionally, as described in JP-A-59-171695, an electronic blackboard device capable of reading information written on a large-sized writing medium and printing it on recording paper has been widely used. Have been.

Also, as shown in Japanese Utility Model Application Laid-Open No. 63-83856, there has been proposed an electronic blackboard device having a structure in which one end of a writing medium is a free end and the other end is wound into a main body. According to such a structure, the entire device can be made compact when not in use.

[0004]

However, if the writing medium is wound up and stored for a long period of time, the medium itself has a curl, and when the writing medium is pulled out for use, the writing curl is caused by the curl. It has a problem that it is difficult to insert.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a sheet for an electronic blackboard device which is unlikely to have a curl and has no adverse effect due to the curl during use.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a coating is applied on the surface of a polyester film, and an auxiliary member is attached to almost the entire back surface of the polyester film.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described.

FIG. 1 is a perspective view showing an appearance of an electronic blackboard device using an electronic blackboard device sheet according to an embodiment of the present invention, wherein 1 is a housing of a main body of the electronic blackboard, and 2 is a handwriting. This is a writing sheet which is made of a polyester film coated on the side with UV and has a different material 9 adhered to almost the entire back surface, and which can be written and erased with a writing instrument such as a water-based marker. FIG. 2 is a sectional view of the writing sheet. 7
Is a polyester film coated with UV, 9 is another material thicker than the polyester film 7, and 8 is an adhesive material for attaching another material 9 to the back surface of the polyester film 7. The separate material 9 is used to make the writing sheet 2 less likely to have a curl, and to correct the curl during use even if the writing sheet 2 has a slight curl. No. 2 brings about the effect of an underlay to improve the writing condition irrespective of the material on the back side. The separate material 9 is lightweight, highly flexible, has a high self-recovery property, and tends to return to a shape before being wound when an external force holding the wound shape is removed, and has an elastic sponge. Materials such as felt, cork sheet, plastic sheet, PVC cardboard, cloth, urethane, and CR rubber are used. 3 is a handle attached to one end of the writing sheet, 4
Is a lid of the printer unit inside the housing 1,
The cover 4 is opened and the thermal paper 5 is set. Reference numeral 6 denotes an operation unit having a sheet winding key and a copy key. FIG. 3 is an AA cross section of the electronic blackboard device shown in FIG. In the drawing, reference numeral 10 denotes a take-up roller for taking up a writing sheet, and reference numeral 11 denotes a reading unit that optically reads characters and figures written on the writing sheet 2 and converts the characters and graphics into electric signals. Reference numeral 12 denotes a sensor provided in the opening 13 of the housing 1, which detects the completion of the winding of the writing sheet 2 by detecting the handle 3. Reference numeral 14 denotes a thermal head for recording characters and graphics read by the reading unit 11 on the thermal paper 5, and reference numeral 15 denotes a platen.

FIG. 4 is a block diagram of the electronic blackboard apparatus shown in FIG. 3, and 16 controls the whole apparatus such as winding of the writing sheet 2, reading of contents written on the writing sheet 2, and printing. It is a control unit. 17 is a winding roller 1
Reference numeral 18 denotes a platen motor for driving the platen 15.

The operation of the electronic blackboard of the present embodiment configured as described above will be described below. However, it is assumed that the writing sheet 2 is drawn to the maximum from the opening 13 for writing.

First, when the control unit 16 detects that the copy key on the operation unit 6 has been operated, the control unit 16 controls the winding roller 10.
Rotates the screen motor 17 in the direction of rotation in the direction of arrow M in FIG. When the take-up roller 10 is rotated by the screen motor 17, the writing sheet 2 is taken up by the take-up roller 10. When the sensor 12 detects the completion of the winding of the writing sheet 2, the control unit 16 stops the rotation of the screen motor 17.
At the same time as winding starts, the control unit 16
1 causes characters and figures written on the writing sheet 2 to be read. Thereafter, the control unit 16 drives the platen motor 18 to rotate the platen 15 and feed the thermal paper 5 while
The data read by the reading unit 11 is transferred to the thermal head 1
4 causes printing on the thermal paper 5.

[0012]

According to the present invention, a different material (sponge,
(Felt, cork sheet, plastic sheet, PVC corrugated cardboard, cloth, urethane, CR rubber, etc.) can be applied to the sheet so that it is less likely to have curl, and the curl can be removed in a short time when it is wound and pulled again. Has an effect.
