Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch operating device that has a simple configuration and allows remote control of a changeover switch.

Conventionally, for example, a tape recorder or the like is configured to set its tape drive circuit to a recording state by switching a recording/playback switch from a playback side to a recording side when operating a recording operation lever.

In addition, in the case of such a tape recorder, when the recording operation lever and the recording/playback selector switch are arranged close to each other, the switch operation device can be made compact with a simple configuration. However, in the opposite case (i.e., when the recording operation lever and the recording/playback switch are separated from each other), a release or plunger drive or a large link mechanism is required, which increases the size of the device and makes it difficult to switch between them. It also took time to adjust the timing.

The present invention has been developed in view of these points, and even if the changeover switch and the operation lever for operating the changeover switch are arranged at positions apart from each other, the changeover operation of the changeover switch using the operation lever can be easily performed. It is an object of the present invention to provide a switch operation device that can be operated reliably with a simple configuration.

Hereinafter, a case in which the switch operation device of the present invention is used for switching a recording/playback switch of a tape recorder will be explained with reference to the drawings.

That is, 1 in the figure is a recording/playback changeover switch having a sliding switching rod 1a that is always energized in the protruding direction (direction of arrow A), and 2 is the position where the recording/playback changeover switch 1 is installed. This is a printed circuit board in which a guide groove 2a is formed in the vicinity, and on the printed circuit board 2, the recording/reproduction changeover switch 1 and other circuit parts are arranged. 3,
Reference numerals 4 and 5 indicate operation levers for recording, rewinding, playback, etc., which are slidably disposed on a mechanical chassis 6 located away from the printed circuit board 2, and each lever is always kept in a non-operating position by a return spring (not shown). It is assumed that the return force is energized (in the direction of arrow B). 7 is attached to the recording operating lever 3 side by fitting one end 7a into the mounting hole 3a of the recording operating lever 3 and then tightening and fixing it with a mounting screw 8, and attaching the other end 7b to the printed circuit board 2. The other end 7 of the wire 7 is a wire rod that is fitted and held in the guide groove 2a of the wire rod 7.
A step portion 9 is bent near b for pressing the switching rod 1a of the recording/playback switch when the recording operation lever 3 is operated.

Therefore, when the recording operation lever 3 is pressed together with the reproduction operation lever 5 in the direction opposite to the arrow B from the stopped state shown in FIG. 1, the wire 7 also moves into the guide groove 2a.
is moved in the opposite direction of arrow B while being guided by
At the inclined portion 9a, the recording/playback selector switch 1 is turned on.
The switching rod 1a is pressed in the opposite direction of arrow A. Therefore, the recording/playback selector switch 1
is switched to the recording position by pressing the switching rod 1a in the opposite direction of arrow A, thereby setting the tape drive circuit (not shown) to the recording state. The switching position of the switching rod 1a is the first step 9 of the wire 7.
By abutting the second step portion 9c instead of b, the second step portion 9c is held against the return bias. here,
The step difference between the first step portion 9b and the second step portion 9c of the wire rod 7 is designed to absorb the stroke difference between the recording operation lever 3 and the recording/playback changeover switch 1, so that the changeover switch 1 can be switched reliably. In addition, the switching stroke of the switching rod 1a is set to be larger than that of the switching lever 1a, and therefore, when the recording operation lever 3 is operated, it will bend by that amount. Furthermore, by appropriately changing the dimensions of the inclined portion 9a of the wire 7, the switching timing of the recording/playback switch 1 can be adjusted.

Incidentally, FIGS. 3 and 4 show an embodiment in which the recording operation lever 3 is arranged parallel to the printed circuit board 2.

As described above, according to the switch operating device of the present invention, there is provided a changeover switch having a sliding changeover rod that is always urged in the projecting direction, and a guide groove in the vicinity of the position where the changeover switch is disposed. a printed circuit board on which is formed, an operating lever arranged at a position apart from the printed circuit board, one end of which is attached to the operating lever side, the other end of which is fitted and held in a guide groove of the printed circuit board; A wire rod is formed by bending a stepped portion near the other end to press the switching rod of the switch when the operating lever is operated. The switch is moved while being guided by a guide groove, and the changeover switch is switched at the step thereof. Therefore, the changeover switch and the operating lever for operating the changeover switch are placed at positions apart from each other. Even if the changeover switch is operated using a single wire, the changeover switch can be operated reliably using a control lever with a simple configuration.
The effect is of high practical value.
