PURPOSE:To ensure the free control for the up-down position of a magnetic head, by installing the control member over the shifting range toward the radius of the magnetic head to control the up-down position of the magnetic head. CONSTITUTION:A solenoid 25 receives the electric conduction in the reproduction/ recording mode and overcomes the rising force of a spring 18. Thus a rubbing pin 22 plus a lifting plate 17 unified with the pin 22 are pressed down. As a result, a lifting pin 21 drops by a prescribed degree, and a control plate 15 is turned clockwise centering on a pin 27. Accordingly a contact part 15B touching a head attachment stand 32 goes up to cancel the suppression of the constant rising habit of a head 4 due to a spring 14. As a result, the head 4 rises up and then stops still at the position where the core part of the head 4 touches a magnetic sheet 33. |
