Abstract

PURPOSE: To save energy and to improve the manipulation, by holding the operating condition selected with the hold means, even if power application to the electromagnetic coil operated in response to the operation of the selection means selecting the operating condition of the magnetic tape unit is interrupted.
CONSTITUTION: In response to the operation of the selection means selecting the operating condition of the magnetic tape unit, some one of the electromagnetic coils 134, 136, 138, 140 is energized and the cam drive motor is driven. The triangle cam 56 is turned with the drive of the cam drive motor, the cam follower 58 is shifted, and the operating condition selected is formed. On the other hand, in response to the formation of operating condition selected, the microswitch 52 is operated and the power application to the cam drive motor and the said electromagnetic switches is interrupted. Further, in this state, since the cam follower 58 is restricted the position with the triangle cam 56, even if the power application to the said electromagnetic coils is interrupted, the operating condition selected can be held.
