Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic whiteboard device having a white screen movable in the left-right direction and capable of copying the contents written on the screen. Regarding the function of collecting slag.

[0002]

2. Description of the Related Art As an example of a conventional electronic whiteboard device, Japanese Utility Model Laid-Open No. Sho 64-9793 (hereinafter referred to as prior art 2).
Includes an electronic whiteboard main body, a frame having a shape that can be fixed to the main body, rotary shafts provided at both inner ends of the frame, and a plurality of pressing cams attached at positions where an average pressure is applied to the rotary shafts. And a motor connected to the rotary shaft and a cushion as a base body, and a cloth brush around the cushion,
A cleaning frame installed at a position where it can be moved up and down by rotation of the pressing cam, a spring provided at a position to apply a tension between the cleaning frame, an operation panel incorporating a motor drive switch and a lamp, and cleaning There is disclosed an "electronic blackboard" including an ink slag storage tray provided at a position for collecting the ink slag wiped by a frame.

By the way, in the prior art 1, as a means for cleaning the screen portion, a brush for cleaning the screen portion is vertically moved and sprayed near the axis of the screen portion at the right or left end of the electronic blackboard. We collect ink dregs.

However, with the above-mentioned cleaning means, it is impossible to collect the ink dregs when the area other than the center of the screen of the electronic blackboard and the area where the brush for cleaning the screen is operated is cleaned.

In Japanese Utility Model Laid-Open No. 63-188184 (hereinafter referred to as prior art 2), a blackboard erasing operation for wiping off a writing image drawn on a writing surface of a white plate (screen) by erasing the blackboard is performed. Discloses an "electronic blackboard device" in which a storage unit for collecting dust is provided on a shelf for receiving dust falling from the writing surface.

[0006]

As described above, in Prior Art 1, the cleaning frame is moved so that the brush on the frame is pressed against the electronic blackboard film for cleaning. When cleaning the center part of the screen and a place other than the range where the brush for cleaning the screen part operates, the ink residue could not be collected.

An object of the present invention is to solve the above problems and to automatically and entirely clean dust scattered below the drawing surface of a screen with a cleaning brush, and collect the dust. To provide a device.

Here, in the "electronic blackboard device" described in the above-mentioned prior art 2, the accommodating portion for accumulating the dust is simply provided in the dust receiving shelf, and the cleaning brush is interlocked with the screen operation to move the left and right sides. There is no specific description suggesting the technical idea of the present invention in which the tray is scrolled to clean the tray, and the technical idea is completely different from the present invention.

[0009]

DISCLOSURE OF THE INVENTION The present invention for solving the above-mentioned problems provides an electronic whiteboard device having a function of scrolling left and right by rotating a roll-shaped screen,
A shelf arranged below the drawing surface of the screen for receiving dust that falls when the screen is wiped, and a brush that engages with the screen and moves to the left and right to clean the dust that has fallen on the shelf. Characterize.

[0010]

In the electronic whiteboard device having the above structure, the brush cleans the shelves in conjunction with scrolling to the left and right of the screen. Therefore, it is possible to automatically and entirely clean the dust scattered below the drawing surface of the screen with a brush and collect the dust.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to FIGS.

FIG. 1 shows the structure of an electronic whiteboard device according to the present invention. An electronic whiteboard main body 1 is supported by a frame 2 from both sides. On both sides in the frame of the electronic whiteboard body 1,
As shown in FIG. 2, a pair of drive shafts 9a and 9b are arranged,
By rotating these drive shafts 9a and 9b, the roll-shaped white screen 5 can be scrolled left and right.

The front frame of the electronic whiteboard body 1 covers the top, bottom, left and right of the white screen 5, and a body hole 1a extending left and right is formed in a portion facing the lower part of the white screen 5. In the lower part of the white screen 5, as shown in FIG. 3, a plurality of holes 5a are formed in a line at equal intervals in the scroll direction. The content written on the white screen 5 can be read by a reader (not shown) and copied by the copy machine 8.

As shown in the sectional view of FIG. 4, a shelf 3 for receiving dust is provided in a portion of the electronic white plate body 1 located below the drawing surface of the white screen 5. The shelf 3 is formed in the shape of a saucer, and the saucers 6 for collecting dust are detachably set in the lower portions on both sides thereof, and the holes 3a, 3b for dropping the dust in the saucer 6 are formed in the upper portion thereof. Has been done.

The cleaning brush 4 includes a handle portion 4a and a brush portion 4b.
The handle portion 4a has one end inserted from a main body hole portion 1a formed in a lower portion of the electronic white board main body 1 so as to engage with a hole portion 5a of the white screen 5. Further, the other end of the grip portion 4a is engaged with the shelf 3 through the roller 7, whereby the cleaning brush 4 is slidably movable on the shelf 3. The brush part 4b has a length sufficient to clean the top of the shelf 3.

Further, cams 1b for pushing the lower part of the white screen 5 inward are formed on both sides of the frame of the electronic white plate body 1, and the cleaning brush 4 engaged with the hole 5a of the white screen 5 is formed. Has a function to be extracted at both ends.

In the electronic whiteboard device having the above-described structure, the cleaning brush 4 has the hole 5a formed in the white screen 5, and the root of the handle 4a is caught in the brush 5 so that the white screen 5 slides on the shelf 3. Works in conjunction with the scrolling movement of.

On the left and right sides of the frame of the electronic white plate body 1, the white screen 5 is bent by the cams 1b as shown in FIG.
Automatically comes off from the hole 5a of the white screen 5. Therefore, regardless of whether the white screen 5 moves to the left or right, the cleaning brush 4 is in a state of standing by at either end.

The tray 6 is made of resin and has a high elasticity, and has hooks formed on the upper portion thereof. The tray 6 can be easily attached to the shelf 3 by hooking it in a groove formed on the shelf 3 side. it can. Since its removal is also extremely easy, the dust accumulated when the tray 6 is removed can be easily discarded. The roller 7 is attached so as not to interfere with the power of the cleaning brush 4, and is used by being sandwiched between the roller rail provided on the shelf 3 and the cleaning brush 4.

With the above structure, the cleaning brush 4 moves from one end to the other as the white screen 5 scrolls. At this time, the dust that has fallen on the shelf 3 is carried to the hole 3a or 3b provided at the end of the shelf 3 and dropped on the tray 3.

Therefore, in the electronic whiteboard device having the above structure, the cleaning brush 4 is interlocked with the white screen 5 and the shelf 3 is moved.
Dust such as pigments that have moved to the top and dropped on the shelf 3 can be cleaned and collected so as not to scatter, and the collected dust can be easily discarded.

[0022]

As described above, according to the present invention, the electronic whiteboard device capable of automatically and entirely cleaning the dust scattered below the drawing surface of the screen with the cleaning brush and collecting the dust. Can be provided.
