Claims

[Scope of utility model registration request]

a slidable cam body having a magnetic head moving cam portion for switching the position of the magnetic head between a play position and a recording position detection position on the magnetic tape; It is equipped with a biasing means for elastically biasing, a moving means for moving the cam body to the recording position detection position against the elasticity of the biasing means, and a locking means for holding the cam body at the recording position detection position. The force is characterized in that the cam body is configured to return to the play position by the restoring force of the urging means by releasing the lock by the locking means after the head detects a recording location on the magnetic tape. Set-type tape recorder.
