Claims

[Scope of utility model registration request]

(1) In the operation switching mechanism of a tape recorder that enters a fast-forward state by rotating a take-up reel stand rotatably attached to the base at high speed, there is a motor that is driven by a fast-forward signal when in a state other than the fast-forward state, and a motor that is driven by a fast-forward signal. Fast-forward position detection is performed by a combination of a position detection plate that is driven by the position detection plate, a cam portion that operates the head substrate by the drive of the position detection plate, and one or more detection elements by the drive of the position detection plate. a detection unit; a reel motor that rotates at high speed in the fast-forward direction based on a fast-forward position signal from the detection unit;
Operation of a tape recorder characterized by comprising an idler inserted between the reel motor and a take-up reel stand and transmitting the rotational force of the reel motor to the take-up reel stand as the reel motor rotates. Switching mechanism.

(2) The operation switching mechanism for a tape recorder according to claim 1, which is a utility model registration, in which a force l section is integrally formed on one side of the position detection plate and a detection section is formed on the other side.
