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.

Hereinafter, a conventional electronic blackboard device will be described.

FIG. 17 is a perspective view of a conventional electronic blackboard device, in which 101 is a drawing sheet, 102 and 103 are exterior cases, 104 and 105 are hinges, and 106 and 107.
And 108 are legs, 109 is a printer, and 110 is an operation panel.

[0005] The main body is hooked to the legs 107 and 106 by pins (not shown) on the opposite side with the pin 112 and the tongues 104 and 105 interposed therebetween.
13 (the same screw is provided on the opposite side across the hinges 104 and 105). The printer 109 is detachable from the outer cases 102 and 103. After the printer 109 is removed, the outer case 102
And 103 can be folded by the hinges 104 and 105.

When transporting this device, the leg 107
After removing the screws fixing the and to the outer cases 103 and 102, the main body is lowered from the legs. Next, the printer 109 is removed from the outer cases 102 and 103, and the outer cases 102 and 103 are folded. on the other hand,
The legs are unscrewed and the legs 106, 107 and 108 are disassembled. In this way, the whole is disassembled into several parts, packed if necessary, and transported to a target place.

[0007]

However, in the above-described conventional electronic blackboard device, a great deal of labor is required to disassemble the device during transport, and it is very difficult to reassemble after transport. For this reason, there has been a problem that moving the electronic whiteboard apparatus requires a plurality of workers.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a foldable main body having a writing surface, a support member that supports the main body and is capable of expanding and contracting in a lateral direction. A plurality of U-shaped legs that can expand and contract in the horizontal direction, and a plurality of connection members that rotatably connect both ends of the support member and both ends of the leg portions, respectively, By reducing the plurality of legs, rotating the plurality of legs around the connection member to bring them closer to each other, and rotating the folded main body together with the support member, the legs are substantially U-shaped.
The configuration is such that it can be stored inside the letter-shaped portion.

[0009]

According to the present invention, the electronic blackboard device can be compactly folded by using the above structure, and the legs can be used as handles after folding.
This has the effect that one person can transport the electronic blackboard device.
