Description

[Detailed Description of the Invention] This invention relates to an operating device for audio equipment installed in a car, such as a car stereo.

A conventional operating device for a vehicle-mounted audio device will be explained using FIG. 1, taking as an example the operating device for a vehicle-mounted cassette tape player with a radio.

In the figure, reference numeral 1 denotes a cassette tape player with a radio, and the cassette tape player 1 with a radio consists of a player body 1a and a nose portion 1b, and the player body 1a is attached to a car dash board (not shown) or the like in an appropriate manner. Fixed. An operation panel 2 is provided on the front surface of the nose portion 1b, and this operation panel 2 includes a fast forward push button 3, a rewind push button 4, an AM/FM switching push button 5,
Operation push buttons such as a program push button 6, an eject push button 7, and a muting push button 8 are arranged so as to be pushable. The push button bodies of each of the push buttons 3 to 8 are always appropriately protruded from the two surfaces of the operation panel, each of which has a return tendency. 9
1 is a cassette insertion hole, and 10 is a receiving frequency display section.

However, in such a conventional operation device for in-vehicle audio equipment, the push button body for operation always protrudes an appropriate amount from the front of the operation panel 2, so the human body may come into contact with the push button when getting on or off the vehicle. However, it cannot be said that it is a desirable structure from the point of view of safety, and there are problems in this respect. In addition, push-type switch operation mechanisms are often used in car audio equipment because of their ease of operation, but in conventional operation devices, part of the push button body is attached to the front of the operation panel. There was also the problem that it was difficult to incorporate novelty into the design of the panel section due to the structural constraint that it was always protruding.

This idea was created by focusing on these conventional problems, and consists of an operation panel base that is located on the front of a push switch installed in the operation section of an in-vehicle audio equipment and covers the switch body; A lamp installed inside the operation panel base, an operation hole into which the actuator enters is formed in each part of the operation panel base that the actuator of the press switch faces, and a lamp is installed on the front side of the operation panel base. A transparent flexible sheet is provided to cover the operation hole, the actuator is operated via the flexible sheet, and the front surface of the operation section is made flat by the flexible sheet. , aims to solve the above problems.

The following is a second example in which this invention is applied to an operating device for a car-mounted radio-equipped cassette tape player.
Description will be given based on the embodiments shown in FIGS.

In each of the figures from FIG. 2 onwards, the same or equivalent members or parts as in FIG.

First, to explain the configuration, as shown in FIGS. 2 and 3, an operation panel base 2a is integrally manufactured on the front surface of the nose portion 1b, and this operation panel base 2a
For fast forwarding, rewinding, AM/FM switching,
Operation holes 13,
14, 15, 16, 17, and 18 are drilled, respectively. And each of these operation holes 13,1
Actuator portions 20a, 4, 15, . . .
Press switches S1, S2, S3 for fast forwarding, rewinding, and AM/FM switching are installed on the operation panel so that the buttons 20b and 20c face each other and enter the operation holes 13, 14, 15... It is arranged inside the base body 2a. Reference numeral 21 denotes a printed circuit board, and this printed circuit board 21 is fixed to the nose portion 1b via L-shaped fittings 22, 22 at a position spaced apart from the operation panel base 2a by a required distance. Each of the pressure switches S1, S2, S3
is fixed to this printed circuit board 21.

Then, a translucent flexible sheet 2b made of resin or the like covers each operation hole 13, 14, 15...
is attached to the front surface of the operation panel base 2a.

Note that the flexible sheet 2b may have an area that at least covers each of the operation holes 13, 14, 15, . . . .

As described above, in this invention, the operation panel 2 is constituted by the operation panel base 2a and the flexible sheet 2b.

Further, on the back side of the flexible sheet 2b at the portions of each operation hole 13, 14, 15..., the operation function is displayed as an example as shown in FIG.
Characters 13a such as (meaning fast forward) are drawn by screen printing or the like.

When a power switch (not shown) is turned on, the characters 13a are illuminated by lamps 23 disposed at appropriate locations and stand out on the front side of the operation panel 2.

Incidentally, the part of the flexible sheet 2b facing the operation hole 13 other than the part where the character 13a is drawn has an appropriate color different from the color of the character 13a in order to clarify the range of the operation part, etc. You may also apply a color.

Next, the action will be explained.

Now, the cassette tape player 1 with radio is
Assume that a cassette (not shown) is inserted into the cassette insertion hole 9 and is being played as a tape player.

When the play progresses appropriately and it becomes necessary to perform a fast-forward operation, when the fast-forward switch operation part on which the character FF 13a is displayed is pressed, the flexible plate 2a is bent, the actuator 20a is driven, and the fast-forward press switch is activated. S1 is turned ON, and the radio-equipped cassette player 1 is set to fast forward mode. To cancel the fast-forwarding state, press the eject switch operation part (part 17) which also serves as a stop function. At this time, the eject press switch (not shown) is activated in the same manner as described above to cancel the fast forwarding state.

As detailed above, this invention consists of an operation panel base that is located in front of a press switch provided in the operation section of an in-vehicle audio equipment and covers the switch body, and an inside of this operation panel base. and a lamp installed in the front surface of the operation panel base, forming operation holes into which the actuators enter in each part of the operation panel base facing the actuator of the press switch, and forming each operation hole on the front surface of the operation panel base. A transparent flexible sheet is provided to cover the
Since the actuator is operated via the flexible sheet and the front surface of the operating section is made flat by the flexible sheet, the push button body for operation etc. can be accessed from the front surface of the operating section as in the conventional case. Since it does not protrude, there is no problem when getting on and off the vehicle, resulting in increased safety. In addition, since a flexible sheet is provided on the front surface of the operation panel base to cover the operation hole, the peripheral wall of the operation hole receives the bending of the flexible sheet. Only the desired actuator can be operated through the press switch, and the effect of preventing other unintended actuators of the push switch from being operated can also be obtained.

Furthermore, since no operation buttons or the like protrude from the operation panel, an effect of an extremely simple design can be obtained.

Furthermore, since the light emitted from the lamp leaks from the transparent flexible sheet through the operation hole provided in the operation panel base, the position of the push switch becomes clear and the surrounding wall of the operation hole is The effect is that it looks like a button and has a modern feel.

Furthermore, unlike the conventional example, it is not necessary to provide a push button body for each operation part, so the number of parts can be reduced, the configuration can be simplified, and the number of assembly steps can be reduced. This has the effect of reducing costs.
