Description

[Detailed description of the invention] B. Industrial application field The present invention relates to an electronic whiteboard.

Conventional technology Conventionally, this type of electronic blackboard stands perpendicular to the floor, and the sheet runs vertically or horizontally, and when drawing characters and figures on the sheet surface, The artist was writing in a standing position facing the front of the electronic blackboard.

Means for Solving Problem C1 In order to solve the above-mentioned problems, the present invention provides a driving roller and a direction changing roller that are arranged substantially parallel to each other and on a horizontal surface so that the endless sheet can run substantially horizontally on the machine base. It is placed above.

An endless sheet having a display surface is placed in a substantially horizontal state between a driving roller and a direction changing roller which are provided substantially parallel to each other on a horizontal plane.

E. Example 1 In Example 1, an endless sheet made of flexible material that can be written on and erased is used, and this sheet 1 is arranged approximately parallel and horizontally.
It is wound around a driving roller 2 and a direction changing roller 3. A roller gear 4 is integrally provided near one end of the drive roller 2. As shown in the first diagram, the rollers 3 for direction change are connected to the front side plate 5a of the machine base 5 and the front side plate 5.
It is rotatably provided between the parts b. Further, the drive roller 2 is rotatably provided between a front rocking plate 6 and a front rocking plate 7 provided inside the side plates 5a and 5b, respectively. As shown in the two figures, a drive motor 8 and an idle gear 9 are provided, respectively.

The drive motor 8 is integrally provided with a drive gear 10, and by operating the operation unit 11, the drive motor 8 rotates and passes through the drive gear 10, the idle gear 9, and the roller gear 4 to the endless sheet 1. is MI3D
It is movable in the directions of arrows A and B. Further, the swing plate 6 and the front swing plate 7 are capable of swinging around a pair of rotating shafts 12a and 12b provided inside the side plates 5a and 5b, respectively, to take up slack in the endless sheet 1. A pair of springs 13a and 13b are stretched between the swing plate 6 and the side plate 5a, and between the swing plate 7 and the side plate 5b, respectively. Further, in order to facilitate drawing on the display surface of the endless sheet 1, a holding plate 14 is positioned on the back surface of the sheet 1 and is integrally provided on the side plates 5a and 5b between the rollers 2 and 3.

As shown in FIG. 2, the optical mechanism mainly includes a fluorescent lamp 15, a mirror 16, and a lens 17 provided below the rotating roller 3, and a copying machine 18 as a recording means provided below. The sheet 1 on which information such as letters and figures is displayed is moved by the rotation of the drive roller 2, and the information such as letters and figures placed on the bottom surface of the sheet 1 is irradiated by the fluorescent lamp 15, and the mirror 16 refracts the optical path of the image, the lens 17 reduces the image, and the copying machine 18
0 slots) A plain recording paper 18b on which information such as characters and figures displayed on the sheet 18a is recorded is discharged to the outside of the machine. In addition, 19 is a power supply controller, and the above-mentioned part 8,
The operation of the fluorescent lamp 15, the copying machine 18, etc. is controlled.

The above is an example in which plain paper 18b is mainly used, but even if a CCD and a binarization circuit are provided below the lens 17 and images are recorded on thermal paper, the same effect as described above can be achieved. It can be implemented.

As described in detail, the present invention provides a driving roller and a direction changing roller so that the sheet can run on a substantially horizontal surface, so that a drawer can draw characters, figures, etc. in a meeting or the like. When doing so, multiple drawers can sit on chairs and draw and hold meetings across the electronic blackboard, instead of writing in a standing position facing the front of the electronic blackboard as in the past. Instead, the drawn image can be immediately recorded on recording paper by operating the operating section, which has a great effect.

Claims (1)

[Claims] An endless sheet having a writeable and erasable surface is wound around a driving roller and a direction changing roller arranged substantially in parallel so that it can be moved by the rotation of the driving roller, and the display surface of the endless sheet is displayed. In an electronic blackboard in which information such as characters and figures is recorded on recording paper through a reading means and a recording means by moving and scanning an endless sheet, the driving roller and the direction changing roller are placed on a substantially horizontal plane of the machine base. An electronic blackboard characterized by being installed at a certain location.
