Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an operating device in which an operating button of an electronic device can be covered with a door that can be opened and closed.
The present invention relates to an operation device in which operation buttons that are infrequently operated are arranged on the back surface.

[Summary of the Invention]

Regarding an operation device capable of covering an operation button with an openable door, a step is provided on a mounting surface of the first and second operation parts, and at least one of the operation parts is integrated inside the door at a substantially right angle to the surface of the door. 2 and there is an electronic step when the door is opened.
An operating device in which a plurality of electronic components that are respectively operated by operating one operation button unit are mounted on the same printed circuit board.

[Conventional technology]

For electronic devices such as TV receivers and VTRs, pushbuttons and /
Alternatively, a structure is often used in which an operation button such as a changeover switch can be covered with a door when not in use. In particular, it is often practiced to cover an operation button, which is rarely used, with a door to facilitate operation.

An example of the conventional method is shown in FIG. The operation button covered by the door on the right side of the external view of FIG. 5 (a) is, for example, FIG. 5 (b).
It is made like a perspective sectional view. A printed circuit board on which a tact switch is attached is often arranged so as to face the respective operation buttons in both the frequently used operation buttons and the infrequently used operation button portions. In the case of this configuration, since the operation buttons that are frequently used are attached to the front panel and the operation buttons that are rarely used are attached to the door, it is necessary to separately prepare the printed circuit boards.

Further, in this configuration, there is a problem that even the frequently used operation button cannot be accommodated when it is desired to be housed in the door when it is not used. This is an inconvenience in designing equipment suitable for popularization of remote control.

On the other hand, when the operation button part is not used, it is housed inside the electronic device frame, and when the operation button part is used, the structure pops out from the front of the electronic device frame, so that the operability of the frequently used operation button is improved. Japanese Patent Publication No. 61-12433 discloses an example in which both the housing and the housing inside the frame when the operation button is not used are compatible.

However, even with the technique of the Japanese Patent Publication No. 61-12433, there is a need for complicated assembly such as providing a printed circuit board on a narrow substantially L-shaped door and pulling it out with a wire harness.

[Problems to be solved by the invention]

By solving the problems described in the related art, the operability of the frequently used operation button is good, and the operation button can be housed in the frame or covered with a door when not in use, and has a simple structure. There is a problem in obtaining an operating device for an electronic device that can be realized by.

[Means for solving the problem]

The electronic device operating device according to the present invention has the following configuration. That is, in an operating device of an electronic device having a first operation button section, a second operation button section, and a door capable of opening and closing the first and second operation button sections, in the first operation button section, The mounting surface and the mounting surface of the second operation button portion have a step difference from each other, and at least one of the mounting surfaces is integrally formed inside the door at substantially right angles to the surface of the door, for example. An electronic component controlled (switched and / or adjusted) by operating the first operation button section and an electronic component controlled (switched and / or adjusted) by operating the second operation button section An operating device for electronic equipment, which is mounted on the same printed circuit board.

Note that when the door is opened, the operation buttons of the first and second operation button sections face and approach electronic switches such as switches and / or variable resistors mounted on the printed circuit board. It is configured to be held in position.

[Operation] In the above-mentioned means, the first operation button section includes, for example, a plurality of infrequently used operation buttons, and the second operation button section includes, for example, a plurality of frequently used operation buttons. .

First, when the door of the operating device is closed (the surface of the door is exposed) so as to cover the first operation button portion with the door, it is integrally formed inside the door at a substantially right angle to the surface of the door. Since the surface (the second operation button part mounting surface) is housed in the frame,
The second operation button portion mounted on the mounting surface is also housed in the frame body.

Next, when the door is opened, the mounting surface is exposed on the front surface of the electronic device, and thus the second operation button portion is arranged at a position substantially aligned with the front panel of the electronic device.

Since the operation buttons of the second operation button section are close to and face the switches provided on the printed circuit board and the electronic components such as the variable resistor, the switches can be operated with the operation buttons.

Since the first operation button portion and the second operation button portion are provided with a step on their mutual mounting surfaces and thus have different distances from the printed circuit board formed of one sheet, the operation buttons of the second operation button portion are different. However, there is a problem that it does not reach the printed circuit board, but this problem is solved by lengthening the operation rod of the operation button of the second operation button section.
