Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a perspective view of an electronic blackboard device according to Embodiment 1 of the present invention, and FIGS. 2 (a) and 2 (b) are cross-sectional side views and plan views of main parts of the electronic blackboard device. 3 is a cross-sectional side view of the electronic blackboard device on the opposite side to FIG. 2A, FIG. 4 is a block diagram of the electronic blackboard device, FIG. 5 is an operation flowchart of the electronic blackboard device, and FIGS. 3) and 3 (c) are explanatory diagrams of the operation of the electronic blackboard device.

In FIG. 1, reference numeral 1 denotes a casing of a main body of an electronic blackboard. It can be wound up freely. The housing 1 has a guide 3 located on one side of the writing medium 2 for guiding the writing medium 2 up and down, a cover 4 of a printer unit provided inside the housing 1, and a writing medium winding key. And a control panel 5 having a copy key. The thermal roll paper 6 is set in the housing 1 with the cover 4 opened.

FIG. 2 shows the construction of the writing medium 2, its winding section and the inside of the housing 1. That is, the sprocket 11 for winding the writing medium 2 is provided in the housing 1 so as to be rotatable by the motor 24.
At the center of each equilateral triangular prism in the writing medium 2 wound by the sprocket 11, shafts 12, 13, 14, 15, 16, 17 for rotating each equilateral triangular prism are provided. 14, 15, 16, 1
One end of 7 is supported by the guide 3. The adjacent shafts 12, 13, 14, 15, 16, 17 are connected to each other by a hinge 18, and the hinge 18 extends when the writing medium 2 is pulled out, and the writing medium 2 is wound. When it is taken out, it bends along the sprocket 11. The sprocket 11 has a pin 2
0 is attached, and the sensor 21 detects the pin 20 and detects completion of winding.

A reading unit 19 for optically reading characters and figures written on the writing medium 2 and converting the characters and graphics into electric signals is provided in the housing 1. The characters and figures are recorded on the thermal paper roll paper 6 by the thermal head 22. 2 in the figure
3 is a platen.

The side opposite to FIG. 2 in the electronic blackboard device is as shown in the side view of FIG. That is, the side chassis 31 having a U-shaped cross section corresponding to the side of the writing medium 2.
, And a sensor 32 for detecting a state in which the writing medium 2 can be pulled out and wound up is disposed on a side of the.

The side chassis 31 functions to fix the regular triangular prisms of the writing medium 2 and to function as a lid when the writing medium 2 is wound and stored in the housing 1. More specifically, the side chassis 31 performs the following three stages of operation (movement in the directions of arrows A and B) during use. In order to regulate the writing medium 2 in the vertical direction when the writing medium 2 is pulled out, the shafts 12, 13, 14, 15, 16, and 17 of the respective regular triangular prisms of the writing medium 2 are fixed to holes in the side chassis 31. Move to the center side as shown in FIG.
(A)). The state in which the writing medium 2 can be pulled out and wound up is detected by the sensor 32. When the writing medium 2 is pulled out and wound up, the writing medium 2 moves outward by one step, which is detected by the sensor 32, and serves as a guide for the movement of the writing medium 2 (FIG. 6B). After withdrawing the writing medium 2, the writing medium 2 is further moved outward by one step, and each regular triangular prism of the writing medium 2 is
13, 14, 15, 16, 17 (FIG. 6)
(C)), a new writing screen can be provided to the user.

The electronic blackboard device has components of a control system as shown in the block diagram of FIG. That is, as the main components, the winding of the writing medium 2 and the writing medium 2
A control unit 41 for controlling the entire apparatus, such as reading and printing of the contents written in the storage unit, a winding motor 24 for driving the sprocket 11, and a random access memory for storing electric signals output from the reading unit 19. Part 4
2, a cylinder mechanism 43 for moving the position of the lid / guide side chassis 31, and a motor 44 for driving the platen 23.

The operation of the electronic blackboard device of the first embodiment configured as described above will be described below with reference to the flowchart of FIG. However, it is assumed that the writing medium 2 is currently drawn out of the housing 1 for writing.

First, upon detecting that the copy key on the operation panel 5 has been operated (step 1), the controller 41 checks the sensor 21 (step 2), and then checks the sensor 32 (step 3). The cylinder mechanism 43 is operated to move the lid / guide side chassis 31 to the guide position (step 4). In step 5, the winding motor 24
Is rotated in the winding direction. When the sprocket 11 is rotated by the motor 24, the writing medium 2 is wound around the sprocket 11, as shown in FIGS. afterwards,
The control section 41 reads the characters and figures written on the writing medium 2 by the reading section 19 and transfers them to the storage section 42 (step 6).

The reading process in step 6 is performed as follows. That is, the control unit 41 outputs a read signal to the reading unit 19 in synchronization with the rotation of the sprocket 11. The reading unit 19 reads one line of characters and the like on the writing medium 2 according to the read signal, and outputs it to the control unit 41. One line of data sent to the control unit 41 is recorded in the storage unit 42.

After writing the data for one line into the storage unit 42, the control unit 41 checks the state of the sensor 21,
If the pin 20 of the sprocket 11 is not detected,
Returning to step 6, the next line of data is read. The processing of the above steps 6 and 7 is repeated until the winding of the writing medium 2 is completed.

When the completion of winding of the writing medium 2 is detected by the sensor 21 at step 7, the control section 41 stops the rotation of the motor 24 (step 8). The control unit 41 drives the motor 23 to feed out the thermal roll paper 6 and prints on the thermal roll paper 6 by the thermal head 20 according to the data stored in the storage unit 42 (step 9).

The above operation is to read and record the image on one side of each of the regular triangular prisms on the writing medium. When the reading and recording of the image on one side is completed, each of the regular triangular prisms is rotated by 60 degrees and a new one is obtained. Writing surface.

In the first embodiment, the number of writing media is six.
Although the equilateral triangular prisms are connected to each other, the prism in the present invention may be a polygonal prism other than a triangle, and the number of polygonal prisms to be connected is not limited to six. Further, the storage of the writing medium in the housing may be performed by using storage means other than the sprocket, and the movement control mechanism of the side chassis is not limited to the illustrated configuration.

[0024]

As is apparent from the above description, according to the present invention, since a writing medium is constituted by connecting a plurality of rotatable polygonal pillars, a screen film becomes unnecessary, and a plurality of writing papers are provided to a user. Since the surface can be provided and the writing medium can be stored in the housing, it has an effect of being compact so as to be easily carried.
