Claims

[Scope of utility model registration request]

The pin holder is rotatably supported on a support shaft at one end, and has a hole in the middle and a size and position for the following operation in relation to the first pin described below, and has a hole at the other end and a head. A head base that is biased forward (toward the magnetic tape side),
One end is pivotally supported on the support shaft so as to substantially overlap the head base, the middle part has a crank arm extending rearward, and the pin receiver has a first pin to be inserted into the hole on the lower surface of the middle part, A pinch roller arm has a pinch roller pivotally supported at its tip, and the two ends are biased forward by a spring fixed to the head base, and a second pin for abutting and pressing the crank arm is attached to the side. It consists of a worm wheel held in the worm wheel and a motor that rotates the worm wheel via the worm.The motor is rotated to bring the second pin into contact with the crank arm and move it slightly, thereby causing the pinch roller at the tip of the pinch roller arm to rotate. Since the first pin, which is separated from the capstan and moved together with the pinch roller arm, has a short movement length, the pin receiver does not press against the periphery of the hole, that is, the first pin does not engage with the helad base. , the head continues to come into contact with the magnetic chip, and it becomes possible to detect between tracks, and by rotating the motor and moving the second pin, the first pin contacts and presses the pin holder against the periphery of the hole. A moving mechanism for a head and a pinch roller in a cassette tape recorder, characterized in that the head base is moved and the head is separated from the magnetic tape to come to a stop state.
