[Industrial applications]

 The present invention relates to an electronic blackboard device capable of reading information such as characters and figures drawn on a sheet and recording the information on recording paper.

[0002]

[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 100 is a writable sheet, 101 and 102 are exterior cases foldably connected by hinge portions 103 and 104, and 105 is an exterior. A printer unit, which is attached to the cases 101 and 102 and can be removed, is a tray unit, which is provided above the printer unit 105, for storing a marker, an eraser, and the like.

When carrying the electronic blackboard device, first, the marker or the like stored in the tray unit 106 is taken out, the printer unit 105 is detached from the outer cases 101 and 102, and then the hinge portions 103 and 104. Thus, the outer cases 101 and 102 are folded to be compact.

[0009]

[Problems to be solved by the device]

 However, in the above-mentioned conventional electronic blackboard device, despite the fact that it was made compact so that one operator could easily carry it, the markers and erasers stored in the tray part had to be carried separately. Furthermore, it has been strongly desired to provide an electronic blackboard device that can be easily transported, that is, one worker can carry it once.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a foldable outer case, a writable drawing sheet in the outer case, and a tray part attached to the outer case for storing a marker or the like. The electronic blackboard device has a configuration in which when the outer case is folded, a part of the outer case closes the opening of the tray section.

[0011]

[Action]

 According to the present invention, when the electronic blackboard device is folded at the time of transportation by the means described above, the tray part is covered with the outer case.
