DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic blackboard capable of sequentially moving a plurality of writable and erasable writing surfaces provided on a take-up curtain to the front and copying and erasing a written image. About.

[0002]

2. Description of the Related Art In a conventional electronic blackboard, an image written on a writing surface on a take-up curtain is copied, erased, and turned off, so that the next writing surface on which nothing is written comes to the front. It is common to stop and leave in that state. In this case, the utility of the electronic blackboard will be further increased if it can be effectively used when the wide surface is not used as the electronic blackboard, from the viewpoint of interior and decoration.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described circumstances of a conventional electronic blackboard, and when the electronic blackboard is not used for its intended purpose, the front portion thereof is used for appreciation of paintings, photographs, and the like. It is an object to provide an electronic blackboard that can be provided to a company.

[0004]

In order to solve the above-mentioned problems, an electronic blackboard according to the present invention is connected to the first or last page of a plurality of continuous writing surfaces provided on a take-up curtain and has a picture in advance. When the power for copying and erasing the image written on the writing surface is turned off, the winding curtain is automatically turned up to the front position. And then stop.

[0005]

Since the electronic blackboard of the present invention is constructed as described above, copying / erasing of the image written on the writing surface is completed.
When the power is turned off, the take-up curtain of the electronic blackboard moves further, the picture surface comes to the front position, stops, and is kept in that state. Since a picture, a photograph, or the like suitable for appreciation is drawn on the picture surface, a decorative effect of the room is obtained, and the utility of the electronic blackboard is increased.

The structure and operation of the present invention other than the above will be apparent from the description of the embodiments described below with reference to the drawings.

[0007]

FIG. 1 is a diagram showing an overall schematic configuration of an electronic blackboard according to the present invention. As shown in FIG. 2, a plurality of writing surfaces 2b are continuously provided in the blackboard main body 1, and a winding screen (scroll) 2 provided with a picture surface 2a connected to the first page is stepped. It is wound and housed on two shafts 9 driven to rotate by the motor 4. The motor 4 is controlled by the control unit 3 so that all the writing surfaces 2b are
The writing surface 2 is controlled so that the amount of rotation as much as possible to scroll (rewind) the rewinding curtain 2 can be rotated forward and backward.
The image written in b is read by the reading device provided in the blackboard main body in the process of being wound around one shaft 9 by the button operation on the operation panel, is copied by the recording device, and is copied to the copy receiver 10. Ejected and erased, the next writing surface appears on the front.

When the power is turned off after the basic functions of the electronic blackboard are completed, the control unit 3 and the motor 4 are operated by the internal battery 5 (see FIG. 2), and the normal writing surface 2 is turned on.
The take-up curtain 2 is scrolled by the motor 4 until the picture surface 2a comes to the front from b. This operation is performed not only by the power off signal but also by a signal from the picture button 6 on the operation panel. FIG. 1 shows this operation.
The state in which the picture surface 2a is exposed on the front of the electronic blackboard 1 is shown.

FIG. 3 shows an example of means for attaching a picture, a photograph, or the like to the picture surface 2a. In this example, a transparent adhesive sticker 7 as seen on the mount of a photo album is adhered to a large part of the picture screen 2a. This transparent adhesive seal 7
A flexible sheet made of polypropylene or the like that can withstand multiple times of sticking and peeling is used. When attaching a painting or a photograph, the transparent seal 7 is peeled off by hand, and a desired painting or photograph 10 is placed at a predetermined position on the winding curtain, and the transparent seal 7 is attached thereon again. wear. At this time, the seal 7 is squeezed while squeezing from the center to the periphery of the picture surface 2a so that air does not enter between the surface of the picture or the photograph 10 and the transparent seal 7 and that the transparent seal does not wrinkle. It is good to stick. In addition, in order to accurately attach the picture or photograph 10 to the center position of the picture surface 2a without tilting, a registration mark (so-called registration mark) 8 for several kinds of paper sizes is written on the picture surface 2a by printing or the like. , Even paintings of different sizes can always be pasted in the center.

In the above-described embodiment, the method of controlling the rotation amount of the motor by the internal battery using the power-off signal as a method of putting the design surface 2a to the front of the blackboard has been described. If the power is not completely turned off until the operation of scrolling until the picture surface comes to the front even when the signal is input, it is not necessary to mount the internal battery 5.

Further, in the above-described embodiment, a picture or a photograph suitable for appreciation is attached to the picture surface. However, a drawing such as a geometric pattern, a map, a strategic drawing, or the like may be used.

Further, the winding direction of the winding curtain is not limited to the left-right direction but may be the up-down direction.

When the power is turned on again while the picture screen is in the front as described above, the original writing surface is scrolled so as to be in the front.

[0014]

As described above, according to the present invention, the electronic blackboard can be used as an interior while the electronic blackboard is not used for its intended purpose, and the utility of the electronic blackboard is increased.
