Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a writing instrument storage device for an electronic blackboard.

[Technical background of the invention] An electronic whiteboard is a device that transmits information written on an input screen via a telephone line and displays the information on a monitor such as a CRT.

In such electronic whiteboards, the writing implements used are usually housed in a housing case of a writing implement accommodating device that is integrally provided with the input board. A felt pen or the like is used as a writing instrument. Generally, three storage cases are installed in this writing instrument storage device, and each of these storage cases is designated with a color. In such storage cases, felt pens of colors corresponding to those cases are stored. Additionally, these storage cases are equipped with detectors to confirm the use of writing instruments. This detector detects the presence or absence of a felt pen in the storage case, and confirms that the felt pen is being used even if there is no felt pen in the storage case.

FIG. 5 shows the front side of an input board of an electronic blackboard equipped with the above-mentioned conventional writing implement storage device, and FIG. 6 shows the side view thereof.

The input board 1 has an operating section 3 disposed below the input surface 2, and a writing instrument storage device 4 is disposed on the operating section 3.

FIG. 7 shows a cross section of this writing instrument storage device 4.

A circular hole 7 is formed in the face plate 5 and the housing frame 6 of the operating section 3. Further, a mounting bracket 8 is fixed to the back surface of the housing frame 6 with screws 9, and an opening 10 is formed in a portion of the mounting bracket 8 that corresponds to the circular hole 7. The cylindrical housing case 11 is held by the housing frame 6 and the mounting bracket 8. Further, a pen stopper 14 is fixed to the back surface of the bottom plate 12 of the mounting bracket 8 by screws 13, and a notch (not shown) is formed in the tongue piece 14a of the pen stopper 14. Furthermore, in this writing instrument storage device 4,
A guide 15 having a U-shaped cross section is fixed to the bottom plate 12 of the mounting bracket 8 with screws 16. This guide 15 has a shaft 17 fitted with a side plate.
The actuator 18 is rotatably supported by. On the other hand, on one side plate 19 of the mounting bracket 8,
A board 21 is fixed by screws 20, and a photo interrupter 22 is fixedly attached to the board 21.

The actuator 18 has a moment of rotation clockwise in FIG. 7 about the shaft 17, so that one end 18a of the actuator 18 normally rotates toward the pen stopper as shown by the dashed line in the figure. It is located in the storage case through 14 notches (not shown).

The felt pen 23 is inserted and housed in the housing case 11 of the writing instrument housing device 4 formed as described above. When the felt pen 23 is housed in the housing case 11, one end 18a of the actuator 18 comes into contact with the tip of the felt pen 23, thereby pushing the actuator 18 toward the pen stopper 14. At that time, the other end 18b of the actuator 18 is located within the photo interrupter 22.

From this state, store the felt pen 23 in case 1.
1, the actuator 18 rotates clockwise in conjunction with the operation of the felt pen 23, thereby causing the other end 1 of the actuator 18 to rotate clockwise.
8b leaves the photo interrupter 22,
This rotational movement of actuator 18 is detected. That is, the use condition of the felt pen 23 inside the storage case 11 is confirmed by the photo interrupter 22.

In this way, the felt pen 23 inside the storage case 11
If it is confirmed that the storage case 1 is in use,
A signal indicating the color designated as 1 is transmitted to the transmission destination, thereby drawing a line or the like in the same color as the felt pen 23 on the destination monitor.

[Problems with background technology]

By the way, in the above-mentioned writing instrument accommodating device for an electronic whiteboard, in order to attach the rotatable actuator 18, parts such as the mounting bracket 8, the guide 15, and the shaft 17 are required, and in addition, they are each fixed with the screws 9, 16, etc. Therefore, the assembly work was complicated.

[Purpose of invention]

In view of the above circumstances, it is an object of the present invention to provide a writing instrument accommodating device for an electronic blackboard that has a small number of parts and is easy to assemble.

[Summary of the idea]

Therefore, in the present invention, a lid body that has a hole or notch for inserting the actuator and is integrally equipped with a shaft for locking the actuator is fixed to the bottom open end of the storage case, and the shaft of this lid body is fixed to the bottom open end of the storage case. The above objective is achieved by having the actuator supported by the actuator.

[Example of idea]

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows a cross section of an input board of an electronic blackboard equipped with a writing instrument storage device according to the present invention, and FIG. 2 shows an enlarged view of the writing instrument storage device.

The electronic whiteboard input board 31 has a recess 33 and a recess 34 formed on the back side of the face plate 32 of the operation section, and a cylindrical storage case 36 is integrally formed on the bottom wall 35 of the recess 33. It is formed. Further, at the bottom opening end of the storage case 36,
As shown in FIG. 3, a lid 39 is provided which has a slit (notch) 37 in the center and a shaft 38 at the end of the slit 37.

On the other hand, as shown in FIGS. 4a and 4b, the actuator 40 in this writing instrument storage device has a
An elastic tongue piece 41 is formed approximately at the center, and an arcuate recess 42 is formed in the wall facing the free end 41a of the elastic tongue piece 41. The actuator 40 has a thick lower portion in the figure.

The actuator 40 formed in this way is
The elastic tongue piece 41 is bent and the shaft 38 of the lid body 39 is engaged with the recessed portion 42 of the elastic tongue piece 41 to be supported by the lid body 39. The shaft 38 of the lid body 39 is inserted into the recess 42 of the actuator 40.
is accommodated, the elastic tongue piece 41 returns to its original state, thereby causing the shaft 38 of the lid body 39 to connect with the recess 42 of the actuator 40 and the free end 41 of the elastic tongue piece 41.
It is held by a.

Further, in FIGS. 1 and 2, reference numeral 43 indicates a board, and this board 43 is connected to the storage case 3.
It is fixed to a boss disposed close to 6 by a screw 44. A photo interrupter 45 is fixed to this substrate 43.

In the writing instrument storage device formed in this way, when the felt pen 46 is not stored in the storage case 36, the one end 40a of the actuator 40 is inserted into the storage case 36 through the slit 37 of the lid 39. located in

When the felt pen 46 is inserted into the storage case 36, the tip of the felt pen 46 comes into contact with the one end 40a of the actuator 40, thereby causing the one end 40a of the actuator 40 to
0a is pushed into the substrate 43 side. Then, since one end 40a of the actuator 40 is located within the photo interrupter 45, the actuator 4
A rotational motion of 0 is detected. That is, it is confirmed that the felt pen 46 is not in use.

On the other hand, when the felt pen 46 is pulled out from the storage case 36, the one end 40a of the actuator 40 rotates clockwise, and the one end 40a of the actuator 40 rotates clockwise.
Since a moves away from the photo interrupter 45, the rotational movement of the actuator 40 is detected. That is, the usage state of the felt pen 46 inside the storage case 36 is confirmed.

In the above embodiment, the slit 3 is provided in the lid 39.
7 is formed, but the slit 37 may of course be a hole.
