Abstract

(57) [Summary] [Structure] The button 4 of the door unit has an elastic portion 5 and links 7, 8
And a lever 9 are integrally provided, and when the button 4 is pushed, the links 7 and 8 are extended to move the lever 9 and operate the tact switch 16 outside the door 2. [Effect] Since wiring has been eliminated, workability is greatly improved, and the door unit can be manufactured by a general mold maker because electrical parts such as switches have been removed from the door unit, resulting in a lower unit price.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door device with a switch operation button in an AV device or the like, and more particularly to a door device in which a wire processing is eliminated from a switch substrate in a rotating door to improve assembly.

[0002]

[Prior Art]

 In the structure of a conventional door device with operation buttons, for example, a switch substrate is incorporated in a door together with operation buttons as seen in Japanese Utility Model Laid-Open No. 1-133385. In such a conventional technique, the number of man-hours for processing the wire rod that connects the door portion and the device body has not been taken into consideration. This will be described below with reference to FIGS.

FIG. 5 is a perspective view when the door portion of the VTR is opened. In FIG. 5, 1 is a front panel as a base, 2 is a door, 3 is a front panel and a rotary shaft for rotating the door. Buttons 4 are provided on the door, and form the front operation portion of each of these members VTR. FIG. 6 is a sectional view of the button portion, and a door 2 is rotatably fixed to a front panel 1 shown in the figure by a rotary shaft 3. The button 4 is exposed from the hole of the door 2, and the tact switch 16 and the board 5 to which the tact switch is soldered are fixed in parallel with the button 4. The board 15 and the main board 18 are electrically connected by a lead wire 17.

[0004]

[Problems to be solved by the device]

 In the conventional structure shown and described above, when the button 4 is pressed, the elastic portion 5 bends, the tact switch 16 is pressed, and the switch is turned on. The electrical signal is transmitted to the main board 18 via the lead wire 17. When the door 2 is closed (not shown), the door rotates about the rotary shaft 3 and the operation surface of the door is hidden. The lead wire 17 is the longest when the door 2 is closed, and the shortest when the door 2 is opened. Therefore, when the door is opened, the lead wire sags inside the front panel. In addition, this may not only cause the door to open and close irregularly, but not only to protrude from the gap between the door and the front panel to the surface or obstruct the opening and closing of the door, but also to cause wire breakage, which may cause wire breakage. there were. Also, the door must be fixed to the front panel first, and when mounting the front panel to the frame 14, the lead wire 17 and the main board 18 must be connected sufficiently close to the front panel and the frame. For the above-mentioned reason, since the lead wire 17 cannot be made long, this work is very difficult to perform, and there is a drawback that it requires skill and man-hours. The purpose of the present invention is to operate the switch without attaching the lead wire to the door.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, the present invention has a structure in which a tact switch and a substrate are fixed to a frame, power that pushes a button on a door is transmitted by a link, and finally the tact switch is operated by a lever that receives power. To do.

[0006]

[Action]

 The button part stored in the door protrudes from the hole made in the operation surface of the door, and if you press this part with your finger, it will be integrated with the button and the link connected by the hinge will move. , The lever connected to the link by a hinge and one of which is fixed to the door oscillates to operate the tact switch on the substrate fixed to the frame. When you stop pressing the button, the restoring force of the elastic part whose end is fixed to the door works together with the button, and the button returns to its original position. At the same time, the link and lever also return to their initial positions.

[0007]

【Example】

 Hereinafter, the present invention will be described with reference to an embodiment shown in FIGS. This embodiment shows an example applied to a VTR equivalent to the conventional example, and in FIGS. 1 to 4, members and parts equivalent to those shown in FIGS. 5 and 6 are designated by the same reference numerals. However, unless otherwise necessary, the same components as in the conventional configuration will be omitted to avoid duplication.

FIG. 1 is a cross-sectional view of a main part of a door device, a front panel, and a frame, and the door 2 is held by a rotating shaft 3 on the front panel 1 as described above. Further, the door 2 rotates about the rotation shaft 3, which is in a range from substantially horizontal shown in FIG. 1 to about vertical shown in FIG. The operation surface of the door 2 is provided with a hole through which the button 4 projects. The door 2 is provided with a boss 12 and a boss 13 for fixing the button device. As shown in the perspective view of FIG. 4, the button 4 has an elastic portion 5, a fixed portion 6 integrally formed with the elastic portion 5, a link 7 and a link 8 connected by a hinge 11 that bends freely, and a substantially central portion of the link 8. It is composed of a lever 9 connected by a hinge and a fixing portion 10 connected by a hinge to one end of the lever 9. The button 4 and the elastic portion 5 link form a mountain shape with the button 4 at the top. The fixed portion 6 and the fixed portion 10 are fixed by welding or the like at the boss 12 and the boss 13 of the door 2. The board 15 on which the tact switch 16 and the tact switch 16 are soldered is arranged so that the end of the lever 9 opposite to the fixed portion 10 is in the vicinity of the position where the switch is operated when the door is opened. It is fixed to. FIG. 2 shows a state in which the above-mentioned door device is closed, and at that time, the tip of the lever 9 draws a locus like an arrow C. When the switch is operated with the door device having this structure completed as a VTR, when the button 4 is pushed in the direction of arrow D with the finger 19 as shown in FIG. 3, the elastic portion 5 of the button bends. The chevron formed by the link 7 and the button is crushed and the link 8 is pushed out in the direction of arrow E. As a result, the lever 9 also falls in the direction of arrow E to operate the tact switch 16. When the finger 19 is released from the button 4, the elasticity of the elastic portion 5 causes the button to return to its original position. At the same time, the link and lever also return to their original positions.

[0009]

[Effect of the device]

 According to the present invention, the lead wire is not required between the door device and the frame, and various troubles due to the lead wire shown in the conventional example are eliminated. Further, in addition to improving workability, the button device can be integrally formed by plastic molding, so that it is possible to provide a door device with cost merits such as low cost, and its practical value is great.
