Description

[Detailed description of the invention] (a) Industrial application field The present invention allows the actuating member corresponding to the operating button to resist the return spring by pressing the operating button protrudingly arranged on the main body of the cabinet. The present invention relates to an operating button device for a tape recorder that is activated and locked in its operating position to set the tape drive mechanism to a desired operating mode, such as playback.

(B) Prior Art Conventionally, the operation button device of such a tape recorder is constructed as shown in FIG. 4 is a tape drive mechanism disposed inside the cabinet body 1, and 5 is an operating lever slidably disposed on the tape drive mechanism 4, which is connected to a return spring (not shown). When the tape drive mechanism 4 is actuated (slided) in the direction of arrow A, it is locked at the actuation position (dotted line position), setting the tape drive mechanism 4 to a desired operation mode such as playback. Numeral 6 is a synthetic resin fixture screwed onto a boss 7 in the cabinet body 1 with a mounting screw 8, and 9 is rotated by the fixture 6 with its pressing portion 9a protruding outward from the cabinet body 1. The operation button is freely supported by a shaft 10, and is rotated counterclockwise by the pressing operation of the pressing part 9a, and the operating lever 5 is actuated in the direction of arrow A by the operating part 9b. Reference numeral 11 denotes a spring plate for returning the operating button 9 which is screwed onto the boss 7 together with the fixture 6, and is elastically abutted against the contact portion 9c of the operating button 9.

However, in such a conventional configuration, even when the operating lever 5 is locked in its operating position by pressing the operating button 9, the operating button 9 is rotated back to its original position by the spring plate 11. As a result, it is difficult to determine whether or not the operation button 9 is currently being pressed.For this reason, in the past, an LED display or the like was used to make it possible to determine the operation. However, such a conventional method increases the number of parts and requires circuit processing, which requires time and effort to assemble.

(c) Purpose of the invention The present invention has been developed in view of the above points, and it is designed to make it easier to determine whether or not a button is being pressed, without using an LED display as in the past. The present invention aims to provide an operation button device for a tape recorder.

(d) Structure of the invention That is, according to the operating button device of the invention, by pressing the operating button protrudingly arranged on the cabinet body, the operating member corresponding to the operating button is applied to the return force of the return spring. A tape recorder that operates against a resistance and locks in its operating position to set the tape drive mechanism to a desired operating mode such as playback, the operation button being rotatably supported on a synthetic resin fixture. At the same time, the operating button is formed with an arcuate circumferential surface extending in the rotational direction around the rotational fulcrum, and the mounting tool is integrally formed with an elastic tongue piece that is in constant pressure contact with the arcuate circumferential surface. When the operating button is not pressed, the operating button is returned to its non-pressed position by the return force of the return spring, but when the operating button is pressed, the operating button is pressed by the pressing force of the elastic tongue. It is configured to be held in place.

(E) Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that parts that are the same as those in the prior art will be given the same drawing numbers and their explanations will be omitted.

That is, according to the present invention, specifically, as shown in FIG. 2, the circumferential surface 12 of the rotation fulcrum of the operation button 9 is formed into an arc shape in the rotation direction around the rotation fulcrum, and , an elastic tongue piece 13 that comes into pressure contact with the arcuate circumferential surface 12 is integrally molded with the fixture 6 from synthetic resin.

Therefore, when the pressing portion 9a of the operating button 9 is pressed, the operating button 9 is rotated counterclockwise and the operating portion 9b operates the operating lever 5 in the direction of arrow A. 5 is locked in its operating position (dotted line position). Therefore, the tape drive mechanism 4 is set to the desired operation mode, and the operation button 9 is held at its pressed position (dotted line position) by the pressure of the elastic tongue 13 that presses against the arcuate circumferential surface 12 of the operation button 9. Ru. The return of the operation button 9 to its original position (solid line position) is achieved by a separate stop operation which causes the actuation lever 5 to slide back to the solid line position, and the operation button 9 receives the return force. also rotates back to its original position.

In order to more reliably hold the operation button 9 in the pressed position, a recess 14 is formed in the arc-shaped peripheral surface 12 of the operation button 9, as shown in FIGS. 3a and 3b, and the arc-shaped Elastic tongue piece 13 that comes into pressure contact with the peripheral surface 12
A convex portion 15 may be formed in the press-contact portion, and the concave portion 14 and the convex portion 15 may be fitted into each other at the pressed position of the operation button 9 to provide a click feeling.

(f) Effects As described above, according to the device of the present invention, by pressing the operating button protrudingly arranged on the cabinet body, the operating member corresponding to the operating button is actuated against the return spring. The tape recorder is configured to lock the tape drive mechanism in its operating position and set the tape drive mechanism to a desired operating mode such as playback, and the tape recorder includes an elastic tongue that presses against the arcuate circumferential surface of the operation button to maintain the pressed position. Since it is integrally formed with the operation button mount, circuit processing is required like in the past.
This provides an excellent effect in that it can be easily determined whether or not the operation button is being pressed without using an LED display or the like.
