[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 a recording sheet.

[0002]

2. Description of the Related Art In recent years, electronic blackboard devices capable of copying the contents of writing on a blackboard onto recording paper have been increasingly evaluated for their functions such as writing notes and minutes in meetings and the like.

[0003] An electronic blackboard device is usually installed in a conference room or the like. However, since the device is not inexpensive, even if it has a plurality of conference rooms, one electronic blackboard device is installed in any conference room. It is common practice to move to another room as needed and use it.

In this case, the electronic blackboard device is heavy and heavy due to an optical system for reading information on a writing sheet surface, a printer for processing read data and printing it on recording paper, and a power supply unit. Demands for compactness during transportation were increasing, such as requiring several people to carry.

[0005] In order to solve this problem, in recent years, an electronic blackboard body having a writing surface has been proposed to be folded to be compact.

Hereinafter, a conventional electronic blackboard device will be described.

FIG. 18 is a perspective view of a conventional electronic blackboard device, in which 100 is a writable sheet, 101 and 102.
Is an outer case that is foldably connected by hinges 103 and 104, and 105 is the outer cases 101 and 1.
Reference numeral 106 denotes a printer unit which is attached to the printer unit 02 and is detachable, and a tray unit 106 provided at an upper portion of the printer unit 105 for storing a marker, an eraser, and the like.

When transporting an electronic blackboard device, first,
Take out the marker etc. stored in the tray unit 106,
After the printer unit 105 is detached from the outer cases 101 and 102, the outer cases 101 and 102 are folded down by the binding units 103 and 104 to make them compact.

[0009]

However, in the above-described conventional electronic blackboard device, the outer case of the electronic blackboard device is not provided.
Depending on the folding direction or attached to the outer case
The electronic blackboard device is folded according to the shape of the printer
When folded, the protruding part of the printer may protrude.
To prevent downsizing when transporting the electronic blackboard device
There was a problem.

[0010]
