。 By locking a locking pawl of a rotatably provided locking lever to one of the locked parts of a drive gear having a cam part with two locked parts separated by 180 degrees from each other, the above-mentioned By blocking the rotation of the drive gear and releasing this lock, the drive gear is
In a running direction switching operation mechanism for a tape drive device that switches the running direction of a tape by rotating it by 0°,
Two auxiliary locked parts are provided near the two locked parts and separated by 180 degrees from each other on the drive gear,
When the locking lever does not rotate back in the direction of locking the locking pawl to the locked portion, the locking portion locks to the one auxiliary locked portion, thereby locking the driving gear. A running direction switching operation mechanism for a tape drive device, characterized in that the rotation of the tape drive device is prevented from rotating.
