In the structure of this example, the push button 5 and slide button 6 described above are molded as an integral molded part 20, as is apparent from FIG.

That is, the integrally molded component 20 is molded into a shape in which the back plate portion 5A of the push button 5 and the back plate portion 6A of the slide button 6 are integrally connected via the connection portion 21.

As shown in FIG. 3A, the connecting portion 21 has a thin portion 2
1a, and the thin portion 21a can be easily cut.

The push-button 5 and slide-button 6 integrally molded component 20 is molded from plastic,
Furthermore, the entire surface is plated.

When the integrally molded part 20 of the push button 5 and the slide button 6 is attached to the housing 2, the push button 5 is attached by welding and the slide button 6 is fitted as shown in FIGS. 7 and 8. The push button 5 and the slide button 6 are separated by mounting and simultaneously disconnecting the connecting portion 21 as shown in FIG. 3B.

Therefore, when the push button 5 is operated, the remaining piece 21A on the push button 5 side does not come into contact with the remaining piece 21B on the slide button 6 side, and when the slide button 6 is operated, the slide button 6 side remains. The remaining piece 21B does not come into contact with the remaining piece 21A on the push button 5 side. Therefore,
The push button 5 and the slide button 6 can be operated smoothly without interfering with each other.

In the structure of the present embodiment as described above, the push button 5 and the slide button 6 are formed as an integral molded part 20, so that they can be handled as one part. Therefore, since only one molding die is required, the cost required for the die can be kept low, and plating can be done in a single process, and the parts can be easily managed, so that the cost can be reduced. .

Further, at the time of mounting, the welding work of the push button 5 and the fitting work of the slide button 6 are performed at the same time in the same process, and at the same time, the connecting portion 21 is cut to separate the push button 5 and the slide button 6. Therefore, the number of steps required for attachment is reduced as compared with the conventional method, and the work efficiency is improved.

In the structure of this embodiment, the push button 5 and the slide button 6 are attached to the housing 2 in such a manner that the height positions of the remaining pieces 21A and 21B of the disconnected connecting portion 21 are different from each other. During each operation, they are operated smoothly without interfering with each other.

Although the embodiments of the present invention have been described above, the present invention is not limited to the cassette player illustrated here, but can be widely applied to various apparatuses having a plurality of types of operation members having different operation directions. .

Further, in the embodiment, the push button 5 and the slide button 6 are used as a plurality of types of operation members having different operation directions.
Although two types of operation buttons are shown, it is needless to say that the present invention can be applied even when there are three or more types.

[0055]

As described above, according to the structure of the present invention, a plurality of kinds of operation members having different operation directions are integrally formed, and the operation members can be handled as one part. Therefore, the die cost is low. In addition, the cost can be reduced because the plating process can be suppressed, the plating process can be performed in one step, and the parts can be easily managed. Further, at the time of attachment, since each operation member is attached at one time and the connecting portion is cut at the same time to separate each operation member, the number of steps required for attachment is reduced as compared with the conventional case, and the workability is improved.

Further, in the structure of the present invention, each operating member is
Since the heights of the remaining pieces of the disconnected connecting portion are different from each other, they are attached to the housing so that they can be smoothly operated without interfering with each other during the respective operations.
