On the other hand, when erasing the written content, the writing surface S is wiped with an eraser (not shown) placed on the pen tray 18 to erase the written content.

In the illustrated electronic blackboard, the stand 10 is provided with upper end portions 12a of left and right leg frames 12,
As shown in FIG. 3, two through holes 21 are provided. On the other hand, the blackboard body 11 is provided with left and right vertical frames 22 of the base frame 14.
Is formed by bending a long sheet metal into a U-shape.
2 a is provided to project downward from the lower edge of the window frame 16. Then, a through hole 23 is formed on the outer surface of the lower end portion 22a.
1 and at equal intervals.

The electronic blackboard shown in FIG.
The printer base 20 and the mounting arm 25 are provided to mount the printer base 20 on the leg frame 12.

The printer table 20 is made of, for example, a metal plate and is formed in a rectangular shape as shown in FIG. 4, and is a short cylinder projecting upward in the figure by burring, for example, two at intervals in the longitudinal direction. And female screw holes a and b are provided on the inner periphery of the short cylinder portions, respectively.

Further, the printer stand 20 is provided with a similar female screw hole c for tray attachment at the center of the front edge in FIG.

The mounting arm 25 is formed, for example, by using an elongated rectangular pipe and bending it into an L-shape, and the through-hole 21 of the leg frame 12 and the vertical frame 2
A female screw hole 27 is provided at an equal interval with the second through hole 23. The other piece 25b is provided with a through hole 28 at an equal interval to the female screw holes a and b of the printer stand 20.

The printer 15 is an ink jet printer in this example, and has a paper feed tray 29 for stacking and setting copy papers attached to the upper rear surface thereof. The paper discharge tray 30 of the printer 15 is made of a resin plate, and is formed by bending a base end 30a and a front end 30b, and has a plurality of ribs 30c on the surface. Then, a through hole 3 is provided at the center of the base end 30a.
1 and a paper receiving portion is formed at the leading end 30b.

At the time of delivery, for example, when assembling the illustrated electronic blackboard according to the user's desire to use the stand, the mounting arm 2 is inserted into the female screw hole a on the front side of the printer stand 20.
5 through holes 28 and screw 33 from below into through holes 28
, And screwed into the female screw hole a to attach the printer stand 20 to the attachment arm 25.

The printer 15 is located on the printer stand 30 as shown in FIG.
Attached near the middle by screwing.
Further, the paper discharge tray 30 is provided with a screw 34 in the through hole 31 from below.
Into the female screw hole c of the printer table 20 through
Is attached to the printer stand 20 as shown in FIG.

On the other hand, the blackboard main body 11 is lifted, and the lower ends 22a of the right and left vertical frames 22 are respectively fitted into the upper ends 12a of the leg frames 12, and screws 35 are passed through the through holes 21 and 23 from the sides, thereby forming the legs. The frame 12 and the vertical frame 22 are connected linearly.

Also, a piece 25a of the mounting arm 25 is applied to the inner surface of the upper end 12a of the right leg frame 12,
The tip of the screw 35 is screwed into the female screw hole 27, and the printer 15 is attached to the right leg frame 12, as shown in FIG. Then, the printer 15 is connected to the back A of the blackboard main body 11.
From the rear so that it does not protrude forward.

In the illustrated electronic blackboard, the stand 1
0, the blackboard body 11 is attached to the wall W as shown in FIG.
You can also use it.

For example, when the user wants to use the camera on a wall at the time of delivery, the through hole 28 of the same mounting arm 25 is aligned with the female screw hole b on the rear side of the printer stand 20 shown in FIG. 33 is screwed into the female screw hole b through the through hole 28, and the printer stand 20 is mounted on the mounting arm 25 as shown in FIG. Then, the printer 15 and the discharge tray 30 are attached to the printer stand 20 in the same manner as described above.

Further, one piece 25a of the mounting arm 25 is applied to the inner surface of the lower end 22a of the right vertical frame 22, and a screw 35 is passed through the through hole 23 and screwed into the female screw hole 27, so that the printer 15 is mounted on the base frame 14a. To the right vertical frame 22. Thus, as shown in FIG. 5 showing the state after the blackboard main body 11 is hung on the wall, the printer 15 is set at a position where it does not protrude rearward from the back surface A of the blackboard main body 11.

In the above-described example, the printer 15 is installed below the right side of the blackboard main body 11 when viewed from the front, regardless of whether the printer is used on a stand or on a wall. But,
In the above-described electronic blackboard, the printer 15 can be installed, for example, below and to the left of the blackboard body 11.

In this case, the mounting arm 2 shown in FIG.
5 is turned left and right, and the printer base 20 is mounted on the mounting arm 25 in the same manner as described above. In the case of using the stand, the mounting arm 25 is attached to the upper end 12a of the left leg frame 12, and in the case of using the wall, it is attached to the protruding lower end 21a of the left vertical frame 21.

In the above-described electronic blackboard, when it is used on a wall, the printer 15 is placed on the right side of the blackboard main body 11 when viewed from the front, as shown in FIG. Can also be installed.

In this case, the mounting arm 2 shown in FIG.
5 is oriented as shown in FIG. Then, the printer base 20 is mounted on the other piece 25b of the mounting arm 25.
Then, one piece 25a of the mounting arm 25 is mounted on the outer surface of the lower end 21a of the right vertical frame 21 using the screw 35 as shown in FIG.

Of course, the mounting arm 25 shown in FIG.
And the printer 15 can be installed on the left side of the blackboard main body 11 by attaching the printer 15 to the outside surface of the lower end portion 21a of the left vertical frame 21. As described above, in the illustrated electronic blackboard, the mounting arm 25 can be mounted in a plurality of modes, and thereby, the position at which the printer 15 is installed can be varied.

In the above-described example, an ink jet printer is used. However, the printer may be another printer such as a laser printer or a thermal printer.

[0041]

Therefore, according to the first aspect of the present invention, the printer is moved back and forth between the position protruding from the back surface of the blackboard main body and the position not protruding depending on whether the printer is used on a stand or on a wall. In order to provide the mounting position adjustable, when using the blackboard body with the stand supported,
The printer can be mounted at a position protruding from the back of the blackboard main body so that it does not protrude forward, thereby preventing the printer from protruding forward and obstructing it as in the related art.

According to the second aspect of the present invention,
Support the printer base on which the printer is mounted with the mounting arm,
By configuring the printer base so that it can be attached to the attachment arm back and forth, the printer can be supported more stably and the attachment position of the printer can be adjusted more easily.

According to the third aspect of the present invention,
Since the mounting arms of the printer can be mounted in a plurality of modes, the positions at which the printers are installed can be varied accordingly.

According to the invention described in claim 4, in addition to the above,
By fixing the paper ejection tray of the printer to the printer base, it is possible to prevent the paper ejection tray from being detached and dropped or damaged.
