Claims

[Scope of utility model registration request]

(1) Place the playback head attached to the head board that is slidable on the base in a position where it comes into contact with the tape, and select a take-up reel stand or a supply reel stand that is rotatably attached to the base to achieve high speed. In an operation switching mechanism for a tape recorder that is placed in a music selection state in which the position of the tape is determined by rotating the tape, a motor is driven by a music selection signal when the tape is not in a music selection state, and a position detection plate is driven by the motor;
A combination of a cam part that operates the head board by driving the position detection plate and brings the playback head attached to the head board into contact with the tape, and one or more detection elements by the drive of the position detection plate. A detection unit that detects the song selection position, a reel motor that rotates at high speed in the fast forward or rewind direction based on the song selection position signal from this detection unit, and rotation of the reel motor that detects the reel motor, take-up reel stand, or supply reel. 1. An operation switching mechanism for a tape recorder, comprising an idler inserted between the stand and the reel motor to transmit the rotational force of the reel motor to the take-up reel stand or the supply reel stand.

(2) The operation switching mechanism for a tape recorder according to claim 1, wherein a cam portion is integrally formed on one side of the position detection plate and a detection portion is formed on the other side of the position detection plate.
