Abstract
PURPOSE: To reduce power consumption and make a unit small-size and lightweight by causing an erasing head to retreat by a spring force without a plunger solenoid for switching to a reproducing mode and by cancelling the spring force by the electromagnetic hold force of the solenoid for switching to a recording mode.
CONSTITUTION: Power is supplied to coil 72 under a state where movable iron core 73 is compressed to fixed iron core 71 of plunger solenoid 25, and iron cores 71 and 73 are separated from each other when power supply to coil 72 is broken. At switching to a recording mode, power is supplied to coil 72, and recording hold slider 76 is pulled to the arrow m direction as shown in the figure by the electromagnetic hold force o solenoid 25 and is held, and erasing head slider 79 advances to the arrow m direction by spring 90, and erasing head 6 is inserted into cassette 9 and is brought into contact with tape 12. Next, at switching to a stop mode, head substrate 4 retreats to the arrow i direction, and head 6 is pulled out from cassette 9.
