In FIG. 1, the positions of the slats 20a to 20f shown by the dotted lines are the slats storing positions when the left and right doors 2 are fully opened, and the slats 20a to 20c and the slats 20d to each of the left and right three plates are stored. 20f is guided by the guide rails 13 and is housed so as to wrap around to the rear side of the conference device 1.

On the front face of the conference device 1, since the sliding door door 2 and the flap door 3 are made of slats of the same size and have a flat surface, the slats 20a to 20f are opened and closed when the door 2 is opened and closed. It is necessary to perform a flap operation for opening the slats 20g and 20h forming the flap door 3 so that the flaps can move.

The flap door drive mechanism 6 is provided to perform the above flap operation, and is attached to the low speed motor 30 that rotates in synchronization with the rotation of the drive motor 22 and the rotation shaft of this low speed motor 30. The roller shaft 31 for urging the flap door 3 (slats 20g, 20h) in the opening direction and the coil spring 32 for urging the flap door 3 in the closing direction. Since the conference device 1 is symmetrical, only the left side is shown in FIG. 7.

That is, it is normally closed (at this time,
When the door 2 is opened, the low-speed motor 30 is rotated counterclockwise in synchronization with the rotation of the drive motor 22, so that the shaft 31 with rollers is moved to the shaft 31 with rollers as shown in FIG. The flap door 3 is moved to the position shown by the solid line and pushed open to secure the orbit of the door 2 (slats 20a to 20c and 20d to 20f).

After the opening / closing operation of the door 2, the low speed motor 30 is rotated clockwise to release the pressing of the flap door 3 by the shaft 31 with rollers, and the flap door 3 is closed by the urging force of the coil spring 32. .

In the present invention, a slit horn speaker having a vertically elongated slit 33 is used as the speaker 8, and the slit horn speaker is installed adjacent to the flap door 3 and symmetrically on both sides of the frontage.

FIG. 8 is a front view of this slit horn speaker, and FIG. 9 is a sectional view taken along the line BB. Since both left and right have the same effect, only the left speaker will be described. The slit horn speaker includes a tweeter speaker 34, woofer speakers 35a and 35b, and a full-range speaker 36.

A horn tweeter is used as the tweeter speaker 34, which places the most importance on the performance of directional characteristics,
As shown in the drawing, the slits 33 are provided to enhance the directivity, and the front surfaces of the woofer speakers 35a and 35b are provided at a predetermined angle via a partition plate 37 so that the front surfaces of the woofer speakers 35a and 35b are directed. The rear surface is connected to the port portion 39 formed in the lower portion through duct holes 38a and 38b formed in the partition plate 38.

Reference numerals 40 and 41 denote partition plates, and the partition plate 41 is attached together with the partition plate 36 at the angle shown.

With the above structure, it becomes possible to reduce the directional characteristics of the slit horn speaker to such an extent that the practical limit is not exceeded in a predetermined direction with respect to the front axis.

The whiteboard lifting device 10 is used to raise the whiteboard 9 normally stored in the lower part of the front surface of the screen 7 to the front surface of the screen 7 when using it, and lower it as needed to store it. is there

The whiteboard lifting device 10 includes upper and lower guide bases 42 and 43 and upper and lower guide bases 4.
A pair of slide rails 4 that connect 2, 43 at both left and right ends
4, 45 and a pair of cross arms 46, 47 provided so as to intersect between the upper and lower guide bases 42, 43 in a front view.
And a cross arm 46, 47 via a rod receiver 48 and an actuator 49 for pushing or pulling.

The upper and lower guide bases 42 and 43 have, for example, a U-shaped cross section and are arranged parallel to each other so that the guide rollers 50a and 50b provided at the right ends of the cross arms 46 and 47 can move. .

The slide rails 44 and 45 support the upper guide base 42 at both ends of the guide bases 42 and 43, and are constructed so as to be slidable in the vertical direction.

The slide rails 44, 45 are provided with a holding mechanism (not shown), and are configured to maintain the state shown in FIG. 10 unless the actuator 49 is driven.

The left ends of the pair of cross arms 46 and 47 are pivotally supported by the upper and lower guide bases 42 and 43, and the right ends of the pair of cross arms 46 and 47 are guided through the guide rollers 50a and 50b provided at the tips as described above. It is slidable in the left-right direction along the lines 42 and 43 as shown in the figure.

The rod receiver 48 is a pair of cross arms 4.
An intermediate portion is rotatably supported coaxially with a shaft 51 that connects the actuators 6 and 47, and the actuator 4 is attached to the end portion thereof.
As shown in the figure, the tip of a rod 52 (one end of an actuator 49) that is vertically expandable and contractible is pivotally supported.

The other end of the actuator 49 is pivotally supported by a base portion 53 provided on the upper guide base 42,
A drive motor 54 for expanding and contracting the rod 52 is provided.

Since the whiteboard lifting device 10 is constructed as described above, when the rod 52 is extended from the state shown in FIG. 10, the rod receiver 48 is pushed downward, so that the upper and lower guide bases 42 and 43 are moved along. The right ends of the cross arms 46 and 47 move to the right.

At the same time, the holding mechanism of the slide rails 44 and 45 is released, and the slide rails 44 and 45 start to shrink, and the length of the slide rails 44 and 45 is reduced to the length of the longest slide rails 44a and 45a. Therefore, the upper guide base 4
The whiteboard 9 placed on the 2 is lowered to a position where the lower edge thereof corresponds to the length of the slide rails 44a and 45a.

The door 2 is opened and closed by turning on the drive motor 22 with the open and close buttons, and the whiteboard is raised and lowered by turning on the drive motor 54 with the whiteboard up button and the whiteboard down button. (Neither button is shown).

Since the present invention has the above-mentioned configuration, it operates as follows. When the door open button for driving the drive motor 22 is turned on from the state shown in FIG. 1, the low speed motor 30 rotates counterclockwise in synchronization with the drive motor 22 rotating the motor pulley 23 in the direction indicated by the arrow a. To do.

Therefore, the flap door 3 is pushed open by the shaft 31 with rollers, and the door 2 follows the trajectory of the guide rail.
Can be slid, and the left and right doors 2 open to the left and right.

After the door 2 is fully opened, the drive motor 22
Is stopped, and at the same time, the low speed motor 30 is rotated clockwise to close the flap door 3.

When the door 2 is fully opened, the fixed screen 7 appears in front of the frontage, and the video projector (not shown) can project on the screen 7.

At this time, since the speaker 8 has the port portion formed in the vertically long slit 33 close to the frontage,
A sound image in the screen direction can be obtained in combination with the excellent directional characteristics of the speaker 8 described above.

When the whiteboard 9 is to be used for the purpose of explanation, the actuator 49 is driven so that the rod 52 is reduced by turning on the whiteboard raising button to turn the whiteboard 9 on the screen 7. The lower part of the front surface of the screen is raised to the front surface of the screen 7 and stopped at a predetermined position.

On the contrary, when lowering the whiteboard 9, the whiteboard lowering button is turned on and the actuator 49 is driven so that the rod 52 extends, and the whiteboard 9 is lowered below the front surface of the screen 7.

When the use of the conference device 1 is finished, the closing button for driving the drive motor 22 is turned on, and the drive motor 22 rotates at a low speed in synchronization with the rotation of the motor pulley 23 in the direction opposite to the arrow a. The motor 30 rotates counterclockwise.

Therefore, the flap door 3 is pushed open by the shaft 31 with rollers, and the door 2 follows the trajectory of the guide rail.
Can be slid, and the left and right doors 2 are closed.

After that, the drive motor 22 is stopped, and at the same time, the low speed motor 30 is rotated clockwise so that the flap door 3
Close. Although the whiteboard is moved up and down in the present embodiment, the screen may be moved up and down. In addition, although the whiteboard is used as the description means in this embodiment, it is needless to say that a conventionally known blackboard may be used instead.

Further, if the above-mentioned open door button, close door button, whiteboard up button, and whiteboard down button can be operated by remote control, the conference device can be made more excellent in operability.

[0060]

As described above, according to the conference apparatus of the present invention, the following effects can be obtained. Previously, the left and right storage spaces required to store whiteboards and doors were eliminated, and in the case of a whiteboard, it was stored at the lower front of the screen, and in the case of a door it was stored at the rear of the device, so the conference device is small. As a result, it is possible to save the space for the installation location and to use the left and right storage spaces for other purposes.

Since the port portion of the speaker is vertically arranged close to the frontage, the sound image is in the screen direction in combination with the excellent directional characteristics of the speaker. Therefore, the positional relationship between the screen and the sound emitted from the speaker becomes natural, and the viewer can feel the presence.

When the conference device is not used, the front face of the conference device is flat, so that a sense of unity can be felt with the surrounding wall surfaces, and the interior is excellent.
