Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an operating device used in electronic equipment such as a CATV system.

2. Prior Art Conventionally, electronic equipment in the CATV industry has often been attached with a remote control transmitter in order to enable its operation from a remote location. That is, the electronic device is normally operated by operating buttons on a remote control transmitter. However, as a backup in case the remote control transmitter breaks down or is lost, it is normal to provide the minimum necessary operating functions so that the electronic device can also be operated.

An example of the above-mentioned conventional electronic device operating device will be described below with reference to the drawings.

Fig. 4 is a front perspective view of a conventional electronic device operating device, Fig. 5 is a sectional view taken along the Y-Y line in Fig. 4, and Fig. 6 is a C in Fig. 4.
It is a partially cutaway plan view in the direction of arrows. In Figures 4 to 6, 15 is the housing cover, 16 is the operation button, 1A is the recess in the front of the housing cover, 18 is the base of the operation button integrally molded with the housing cover, and 19 is the operation button. Arm part, 20 is the panel, 21 is the slit, 22 is the housing body, 23 is the printed circuit board, 3-7 24 is the switch, 26 is the leg of the operation button, 26 is the movable part of the switch, 27 is the rest rib .

The operation of the electronic device operating device configured as described above will be described below.

In an electronic device operating device in which a recess 17 is formed in a part of the front part of the case cover 15 and an operation button 16 is arranged in this part, the operation button 1e is molded integrally with the case cover 15 and its arm. 19 is formed thinly relative to the base 18, and is bent by the elasticity of the plastic when the operation button 16 is pushed in the direction of arrow B (FIG. 5).

Further, a panel 20 is provided on the surface, and this covers a slit 21 that is inevitably created because the movable operation button 16 and the housing cover 15 are integrally molded, and also displays an explanation of the operation. On the other hand, a printed circuit board 23 on which a switch 24 necessary for operating the electronic device is directly attached is fixed to the main body 22. 26 is arranged. Furthermore, foot 2 of operation button 16
6 and the tip of the movable part 26 of the switch 24, the abutment rib 27 is integrally formed with the housing cover 15 in order to precisely regulate the vertical position of the housing body 22 and the printed circuit board 23. and is provided near the operation button 16.

Problems to be Solved by the Invention However, with the configuration in which the housing cover and the operation button are integrally molded as described above, the operation button can only be provided on the top surface of two sets of plastic mold structures, and the design and There were major functional limitations. In addition, a panel is required on the surface to cover the slit that inevitably occurs when the operation button and the housing cover are integrally molded.
This has the problem of high cost.

In view of the above-mentioned problems, the present invention aims to provide an electronic device operating device in which operation buttons are arranged on the front surface of the main body, a switch directly attached to a printed circuit board can be operated from the front, and a panel is not required. This is the purpose.

Means for Solving the Problems 6 Heno In order to solve the above problems, the electronic device operating device of the present invention has the operation buttons molded in resin as a separate piece from the housing cover,
These two pieces are combined into a single body, and the operation button is arranged on the front surface of the housing cover.

Function: The above configuration allows the switches directly attached to the main printed circuit board to be operated from the front of the set without requiring any parts such as the panel.

Embodiment Hereinafter, an electronic device operating device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front perspective view of an electronic device operating device according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line X--X in FIG. 1, and FIG. 3 is a perspective view of an operation button. In Figures 1 to 3, 1 is the housing cover, 2 is the operation button, 3 is the button part, 4 is the arm of the operation button, 5 is the outer frame of the operation button, 6 is the claw part of the operation button, and 7 is the button part. Operation button mounting hole on the housing cover,
8 is a stopper, 9 is a rib, 10 is a housing body, 11 is a switch, 12 is a printed circuit board, 13 is an operation button foot,
14 is a support rib.

The operation of the electronic device operating device configured as described above will be described below.

In an electronic device operating device in which an operation button 2 is arranged on the front of a housing cover 1, the operation button 2 is a separate piece from the housing cover 1 and is formed by resin molding, and these operation buttons 2 and the housing cover are separate pieces. 1 is mechanically attached. As shown in FIG. 3, the operation button 2 is composed of a button part 3, an operation button arm 4, and an outer frame 6 of the operation button. , and use that as a fulcrum to press operation button 2.
Push the outer frame 5 of the operation button 2 into the stopper 8 of the housing cover 1 to stop it.Press the rib 9 of the operation button 2 against the inside of the housing cover 1, and use the elasticity of the plastic to secure it. Then, fix the operation button 2 to the housing cover 1.

Press button 3 in the direction of arrow A (Figure 2) to go to 7.
7, the arm 4 of the operation button is flexible. - On the other hand, the housing body 10 includes a switch 11 necessary for operating the electronic device.
A printed circuit board 12 to which the button is directly attached is fixed, and the foot 13 of the operation button operates the inlet 11. Furthermore, since dimensional accuracy is required for the foot 13 of the operation button and the tip of the switch 11, in order to precisely regulate the vertical position of the housing body 10 and the printed circuit board 12, the contact lip 14 is required.
is integrally molded with the housing cover 1 and provided near the operation button 2.

As described above, according to this embodiment, the operation button 2 can be attached to the front surface of the housing cover 1 without being restricted in design or function. It is possible to change only the operation button 2 to a material suitable for its function as a button, and the color tone can also be freely changed in terms of design. Since the panel conventionally provided to cover the slit is not required, parts costs can be reduced.

Effects of the Invention As described above, according to the present invention, by making the operation button a creatively molded part, it is possible to arrange the button on the front of the housing cover, which is difficult to do with integral molding due to the mold structure, and its practical use is improved. There is a dog-like effect.
