Claims

[Scope of utility model registration request]

A pair of flywheels driven in opposite directions by a motor, a pair of reel stands on which a tape reel is loaded, and movement between the pair of reel stands to transfer the rotation of either of the flywheels to either reel. An idler rotating body that transmits data to the stand, a switching rotating body driven by the power of the motor, a locking mechanism that stops this switching rotating body at each mode position, a drive unit that operates this locking mechanism, and this switching rotating body. A head base that is stopped at each mode position according to the rotation stop position when the head is locked, a magnetic head mounted on this head base, and a magnetic head that is movably supported by the head base and that controls the rotation of the switching rotor. The mode switching body is moved in either direction by the switching rotary body at a predetermined time, and the switching force of the mode switching body is transmitted via an elastic member, and the idler rotary body is moved in either direction depending on the direction of movement. an idler switching body that moves in the direction of the flywheel and the reel stand; A cam part that allows movement in the direction of the reel stand and the flywheel or restricts this movement, and the cam part allows the idler rotating body to move in the direction of either the reel stand or the flywheel. and a blocking mechanism for stopping the movement of the idler switching body in accordance with the movement of the locking mechanism in the unlocking direction to prevent the idler rotating body from moving in the permissible direction. mode switching device.
