Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a push button operating device used in a tape recorder.

(B) Prior Art Conventionally, when operating the actuated lever of a tape recorder mechanism using a push button lever, it is common to connect a return spring to the push button lever so that a plurality of push button levers are arranged in one line. Ta.

Therefore, according to the push button operating device having such a configuration,
It was necessary to attach a return spring to each of the plurality of push button levers. Therefore, a configuration has been proposed in which a single spring plate is used to apply return force to multiple push button levers, but since the spring plate is configured separately from the bracket that supports the push button levers, The installation work had become troublesome.

(c) Purpose of the invention In order to solve the problems of the conventional method, the present invention
The purpose of this invention is to improve the efficiency of mounting work by integrally forming a plurality of spring pieces for determining the positions of a plurality of push button levers on a bracket that supports the push button levers.

(d) Structure of the invention In order to achieve the above object, the present invention has a push button lever rotatably supported on a bracket integrally having a U-shaped spring piece, and the operating piece of the push button lever is attached to the spring piece. When the bracket is attached to the cabinet, the actuated lever on the operating piece of the push button lever is brought into contact with its return spring.

(E) Embodiments Below, embodiments of the device of the present invention shown in the drawings will be described.

FIG. 1 shows a perspective view of a tape recorder to which the device of the present invention is applied, in which a push button lever 2 is disposed below a cassette mounting section 1. As shown in FIG.

In FIG . 2, reference numeral 3 denotes a synthetic resin bracket which is a feature of the present invention. Walls 6, 6 are formed, and the supporting walls 6, 6 are provided with holes 8, 8 for supporting the pivot shaft 7 of the push button lever, and holes 9, 9 for mounting on the cabinet. ing.

FIG. 3 shows a state in which a plurality of push button levers 2 of the bracket 3 are rotatably supported by a support shaft 7, and the push button lever 2 has its operating piece 2' connected to the free end 5' of the spring piece 5. is in contact with the top surface of the

Therefore, the bracket 3 supporting the push button lever 2 in this way is attached to the cabinet 1 as shown in FIG.
It is attached to a boss 11 provided inside 0 with a mounting screw 12.

A mounting recess 13 for a cassette is integrally formed in the cabinet 10, and a window 14 is formed below the recess 13 through which the operating section 2'' of the push button lever 2 is exposed. A recorder mechanism chassis 15 is disposed, and the chassis 15 is provided with an actuated lever 17 to which a return spring 16 is connected. The portion 17' is brought into contact with the return spring 16.

Since the device of the present invention is configured as described above,
The actuated lever 17 on the mechanism chassis side is moved to the push button lever 2 by the downward force of its return spring 16.
This contact is damped by the upward force of the spring piece 5 on the bracket 3 side, which is in contact with the lower side of the actuating piece 2'.

Therefore, by operating the operating portion 2'' of the push button lever 2, the actuated lever 17 can be moved against the return spring 16 by the actuating piece 2' as shown by the chain line in FIG. I can do it.

(f) Effects of the invention Since the device of the invention is constructed as described above, a plurality of push button levers are supported in advance on the bracket, and each push button lever is supported by a spring piece formed integrally with the bracket. By attaching the bracket to the cabinet with the position determined, each push button lever can be securely brought into contact with the actuated lever on the mechanism chassis side. The actuated lever can be accurately held in the non-operated state by balancing the forces of the return springs, so even if the force of each return spring is different, the buffering action of the spring pieces will keep the operating part of the push button lever intact. It is practical because it does not cause unevenness of the parts, improves the efficiency of the installation work, and is practical.
