That is, one operation button 10, 40 having the pressing body 21 and the rotating body 11 is used for play and fast forward (recording and rewinding).
Will also be used as the operation button. Therefore, according to this example, it is possible to reduce the number of operation buttons arranged in the cabinet 1, eliminate the complexity thereof, and improve the appearance.

Further, according to this example, the operation buttons 10, 40
Since the operating directions of the pressing body 21 and the rotating body 11 are completely different in the pressing direction and the circumferential direction, erroneous operation can be eliminated. In particular, according to this example, since the operating directions (tilting directions) of the lever portions 13 of the operation buttons 10 and 40 are reversed, it is possible to reliably prevent erroneous operations of fast-forwarding and rewinding. Further, according to the present example, since the cylindrical portion 12 of the rotating body 11 constitutes the housing of the pressing body 21, the parts for receiving the pressing body 21 are not required.

In the above embodiment, the operating element 20 of the leaf switch 18 is pressed by using the shaft portion 14, but the member pressing the operating element 20 is not limited to this. For example, the same can be applied to the case where the hook portion 12c of the tubular portion 12 of the rotating body 11 is used. In this case,
The leaf switch 18 is arranged near the edge of the long hole 1a on the operating side. Further, in the above-described embodiment, the present invention is applied to the headphone stereo S,
