 The foot switch as described above is used for a writer or a typist to operate the tape recorder with his / her foot when using the tape recorder for dictation or type, for example. For convenience of dictation or typing, the tape recorder is a transcriber that can quickly change the fast-forward mode, fast-rewind mode, stop mode, and play mode of the tape by using the foot switch as described above. It is widely known and widely used in Europe and America under the name.

There are roughly two types of foot switches for transcribers used in Europe and the United States. In the first type, as shown in FIG. 4, a square-shaped first pedal 10 having no footrest and arranged at the center is used as a play (PLAY) mode setting pedal. The second pedal 12 adjacent to the left side of each of the pedals functions as a fast-forward (FF) mode setting pedal, and the third pedal 14 adjacent to the right side of the first pedal 10 operates in the fast rewind (REW) mode. Functions as a setting pedal.

Here, the rotation center line 10a of the first pedal 10 extends horizontally in the left-right direction along the rear edge of the first pedal 10, and the rotation center lines 10a of the second and third pedals 12 and 14 are rotated. Similarly, the center lines 12a and 14a extend horizontally along the rear edge of the first pedal 10 in the horizontal direction.

A cable 15 connected to a tape recorder, a transcriber, or the like is taken out from the rear surface (front surface) of the foot switch body so as not to interfere with the operation of the foot switch.

The first type foot switch having such a configuration is mainly used in the United States. In the second type of foot switch, as shown in FIG. 5, a square footrest 20 is arranged at the center, and the first pedal 22 adjacent to the front of the footrest 20 is in the fast forward (FF) mode. The second pedal 24 adjacent to the left side of the footrest 20 functions as a rapid rewind (REW) mode setting pedal, and the third pedal 26 adjacent to the right side of the footrest 20 functions as a setting pedal. Functions as a playback (PLAY) mode setting pedal.

Here, the rotation center line 22 a of the first pedal 22 extends horizontally in the left-right direction along the front edge of the footrest 20, and the rotation center line 24 a of the second and third pedals 24 and 26. 26a extend parallel to each other along the left and right edges of the footrest 20 in the front-rear direction.
