Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to audio equipment such as compact disk players (hereinafter referred to as CD players) and tape players.

[Conventional technology]

In general, the operation panel of an audio device is provided with knobs and operation keys for controlling a compact disk or tape cassette inserted into the main body of the audio device to a predetermined position and playing back the same.
Furthermore, a display section using a fluorescent display tube or liquid crystal display is installed on the front of the case to operate the audio equipment, display the track number being played, and how many remaining songs can be played while playing a CD or tape cassette. Together with the aforementioned knobs and operation keys, they form the external appearance of the audio equipment.

Also, if you are lying down indoors or operating audio equipment in a very relaxed state,
In particular, on the front of the case of the audio equipment, an operation board including knobs, operation keys, a display section, etc. is tilted at an angle that is easy for the user to operate the audio equipment.

[Problem that the invention attempts to solve]

However, when a CD or tape cassette is inserted into the audio equipment and played at a predetermined position, static electricity is frequently generated around the display, and as a result, static electricity is generated on the fluorescent display tube, liquid crystal display, etc. The display often appears, which poses a problem in terms of the operability of the audio equipment.

An object of the present invention is to solve the problems of the conventional example described above and to provide an audio device that is easy to operate and does not malfunction.

[Means for solving problems]

In order to achieve this purpose, the present invention surrounds the display part of the operation board made of synthetic resin, which is movably attached to the front surface of the audio equipment and is equipped with at least operation keys and a display part, with a conductor. ,
One end of the flexible printed circuit board is attached to the conductor, and the other end of the flexible printed circuit board is attached to the metal body of the audio equipment body, allowing the static electricity generated around the display to escape to the outside of the audio equipment body, thereby solving the above problem. This is what we are trying to achieve.

[Effect]

In order to operate the operation board of the audio equipment configured as described above, turn on the power switch of the equipment itself,
Furthermore, if you turn on the operation key on the operation board and freely tilt the operation board by the desired angle,
Static electricity generated on the operation board that has the display section propagates from the conductor installed around the display section to the flexible printed circuit board that connects the conductor and the metal body installed on the audio equipment main body, and is transferred to the outside of the audio equipment main body. is released.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes an audio device such as a CD player or a tape player, and an operation panel 2 is provided on the front of the audio device 1. The operation panel 2 is
Operation board support frame 3, operation board 4, and fitting member 5
It consists of.

A plurality of operation key sections 6 and 7 are arranged at predetermined positions on the left and right sides of the operation board support frame 3, and a recess 8 for housing the operation board 4 is provided approximately in the center of the front. Furthermore, the operation key parts 6, 7
A gear wheel 10 is provided near the slide groove 8 for pushing the operation board 4 forward and a gear wheel 10 that is pivotally supported by an opening 9 on the operation board support frame 3. and,
The gear wheel 10 includes a shaft 12 and a reduction gear 13.
is connected to the output shaft of an opening/closing motor 14 installed at one end of the back side of the operation board support frame 3 through the gear wheel 10, and by rotationally driving the opening/closing motor 14, the gear wheel 10 rotates and slides the operation board 4. It is adapted to be slid along the groove 8a.

Further, there is a notch 15 at the rear upper part of the operation board support frame 3, and a locking hole 15a for attaching and detaching the fitting member 5 is formed in the notch 15.

The operation board 4 is provided with a projection 16 formed on its side surface 4a, which is fitted into the sliding groove 8a and is movable along the sliding groove 8a. Similarly, the back surface of the operation board 4 has an arc-shaped curvature, is formed in a convex shape, and is provided with a rack 17 that meshes with the gear wheel 10. Furthermore, a through hole 18 is provided on the back surface of the operation board 4, and a drive circuit for a fluorescent display tube 20 is installed through the through hole 18 on a printed circuit board 19 screwed into the operation board 4. A flexible printed circuit board 21 is provided. At the same time, around the fluorescent display tube 20,
A phosphor bronze plate 22 is provided to ground static electricity generated around the fluorescent display tube 20.

Further, in order to ground static electricity, a flexible printed circuit board 23 is provided, one end of which is soldered to the phosphor bronze plate 22. The other end of the flexible printed circuit board 23 is screwed to the chassis 24 of the audio equipment 1 via a mounting bracket 25.

Next, the assembly of the audio equipment configured as described above will be described.

First, the operation board 4 is attached to the recess 8 provided at the front center of the operation board support frame 3 so that it can be pushed out, and the fitting member 5 is attached to the locking hole 15a of the operation board support frame 3. , one end of a flexible printed circuit board 23 disposed behind the operation board 4 is screwed to the chassis 24.

Also, attach the assembled operation panel 2 to the audio equipment main body 2.
8, and the assembly of the audio equipment 1 is completed.

Next, the operation of the audio equipment will be described. 1st
As shown in the figure, press the power switch 7a of the operation panel 2, which is normally closed, to turn on the power.
When the operation board opening/closing switch 7c is pressed, the opening/closing motor 14 is operated and the reducer 13 and shaft 12 are operated.
The gear wheel 12 rotates via. Then, the rotation of the gear wheel 12 is transmitted to the rack 17, and the protrusion 16 on the side surface of the operation board 4 is brought into sliding contact with the sliding groove 8a provided in the operation board support frame 3, and is moved downward along the sliding groove 8a as desired. While tilting at an angle of , it is moved downward so as to protrude forward, and is stopped at a desired position using a limit switch (not shown). When the operation board 4 approaches the front, the audio equipment main body 2
8 is mechanically and electrically connected via a flexible printed circuit board 21, and as the operating board 4 rotates, the printed circuit board 21 deforms as well, so there is no problem in operation.

When the operation board 4 moves forward or tries to return to its original position, static electricity may be generated near the fluorescent display tube 20 inside the operation board 4. The installed phosphor bronze plate 22 and flexible printed circuit board 23
and propagates through the mounting bracket 25 and chassis 24 and escapes to the outside of the audio equipment 26. As a result, static electricity does not accumulate around the fluorescent display tube 20, and after it is generated, it quickly escapes from the audio equipment via the chassis 24 and the like. Then, the display section 4b of the operation board 4 continues to display normally without being affected by static electricity.

Further, as the operation board 4 moves downward, the opening 11 of the fitting member 5 is exposed, and a compact disk, tape cassette, etc. is inserted into the main body of the device through this opening 11, and played. After that, the compact disk or tape cassette is ejected using an appropriate ejecting mechanism.
