DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic blackboard device used for meetings, education, presentations, etc.
The present invention relates to an electronic blackboard device capable of printing out image information handwritten on a screen sheet by an external printer.

[0002]

2. Description of the Related Art Conventionally, in an electronic blackboard device capable of printing out image information handwritten on a screen sheet by a ready-made printer (hereinafter referred to as an "external printer"), the external printer is attached to the main body of the electronic blackboard. , The following two methods have been adopted.

[0005] A dedicated cradle (printer cradle) is fixed to the electronic blackboard main body, and an external printer is simply placed on the cradle. By fixing a dedicated holder (printer stand) to the electronic blackboard body, screwing a dedicated mounting member to the back of this base, and hooking the mounting member on this using the irregularities on the back of the external printer , Which regulates the forward and backward movement of the external printer on the cradle.

[0004]

However, as described above, it is unstable to simply mount the external printer on the printer base without fixing it on the printer base, and the main body of the electronic blackboard is freely moved by the casters of the stand. Where possible,
If the electronic blackboard body must be inclined at the entrance of the room or on a floor with steps, etc., the electronic blackboard body may fall even if there is no impact, which is extremely dangerous. It is.

[0005] Further, in the case where the mounting member is hooked on the uneven portion on the back surface of the external printer as described above,
Although the front-rear movement of the external printer is restricted on the printer stand, the external printer is not fixed in the vertical direction. Therefore, even if the external printer is not as large as described above, the danger of falling during the movement or the inclined installation cannot be eliminated.

Accordingly, the present invention eliminates the risk of dropping when moving or tilting an external printer by securely fixing an external printer to a printer table provided on an electronic blackboard main body. Another object of the present invention is to make it possible to stably install an external printer on a printer base without preparing a dedicated mounting member on the external printer side.

[0007]

In an electronic blackboard apparatus having a reading unit to be read and a transmission unit capable of outputting information relating to the reading to an external printer, a printer table 7 on which an external printer 8 is mounted is provided on the electronic blackboard main body 1. 7 is provided with a tray guide engaging portion 14a which engages with a tray guide 17 for guiding the output tray 10 of the external printer 8 into and out to fix the external printer 8 on the printer stand 7. I do.

A holding plate 14 whose left and right side edges have an inverted L-shaped cross section
Is provided on the printer table 7, the left and right side edges of the inverted L-shaped section are connected to the left and right tray guides 17 of the external printer 8.
And a tray guide engaging portion 14a that engages with the tray guide engaging portion 14a. Tray guide stoppers 1 are provided at the front ends of the left and right side edges.
4b may be provided.

The printer base 7 supports a base plate 13 on an arm 11 attached to the stand 2 of the electronic blackboard main body 1.
The holding plate 14 as described above may be mounted on the base plate 13.

If a back holding member 18 is provided on the printer base 7 for engaging with a projection or a recess formed on the back of the external printer 8, the external printer 8 can be further stably mounted on the printer base 7. Can be fixed to

[0011]
