[Prior Art]

 In recent years, electronic blackboard devices that can copy the content written on a blackboard onto a recording paper have been highly evaluated for their functions such as writing notes and making minutes in meetings.

The electronic blackboard device is usually installed in a conference room or the like, but since the device is not inexpensive, even if there are a plurality of conference rooms, one electronic blackboard device is installed in one of the conference rooms. It is common practice to install it and move it to another room for use as needed.

In this case, the electronic blackboard device has an optical system for reading information on the surface of the writing sheet, a printer for processing the read data and printing on recording paper, and a power source section, etc. However, because it is large, it takes several people to carry it, and there is an increasing demand for compacting during transportation.

In order to solve this problem, in recent years, an electronic blackboard main body having a writing surface has been proposed to be folded to make it compact.

A conventional electronic blackboard device will be described below.

FIG. 18 is a perspective view of a conventional electronic blackboard device, in which 101 is a writing sheet, 102 and 103 are outer cases having an image reading unit and the like (not particularly shown) inside, and 104 is an outer case. A case lid 105 is a printer unit. FIG. 19 is a perspective view of the electronic blackboard device of FIG. 18 in which the outer case cover 104 and the printer unit 105 are removed and the outer cases 102 and 103 are being folded, and 106 and 107 are the outer case 102. And 103, an intermediate panel for holding the writing sheet 101, 109 and 110 sheet conveying rollers for conveying the writing sheet 101, 111 motors for driving the sheet conveying rollers 109, and 112 and 113 outer case 102. And 103 are foldable portions that foldably connect them.

In the conventional electronic blackboard device, as is apparent from the drawings, after the outer case cover 104 and the printer part 105 are removed, it can be folded by the hinge parts 112 and 113. At this time, in order to prevent the writing sheet 101 from falling off, it is necessary to fix the sheet with tape or the like. On the other hand, when assembling a folded product, it is necessary to open the writing unit, remove the tape or the like holding the sheet, and attach the outer case cover 104 and the printer unit 105.

[0009]

[Problems to be solved by the device]

 However, in the above-mentioned conventional electronic blackboard device, the sheet has to be fixed with a tape or the like each time it is folded and assembled, which is a troublesome work. Therefore, it is strongly desired to provide an electronic blackboard device that can be folded and assembled more easily.

[0010]
