Claims

[Scope of utility model registration request]

A head base that moves the magnetic head between a play position where it touches the tape and a non-play position where it moves away from the tape, a pair of 7-wheel gears that are constantly driven to rotate, and a pair of capstan shafts that rotate together with the flywheel gears. has a reel gear that rotates together with a pair of reel shafts, and a change gear that changes the running direction of the tape by switching the driving force to the pair of reel shafts, and controls the operation timing of this change gear. In an auto-reverse type cassette drive device equipped with an auto-reverse solenoid, the head base is provided with a stopper that restricts rotation of the change gear in a non-play position, and the head base is in a play position. A play idler is provided that transmits the rotation of the flywheel gear to one reel gear when the head base is in the non-play position, and transmits the rotation of the flywheel gear to the eject gear when the head base is in the non-play position; An eject operating device for a cassette drive device, characterized in that an eject lever is provided that is slidably driven to start an eject mechanism, and the drive timing of the eject lever by the eject gear is controlled by the auto reverse solenoid. .
