PHO 77-501 ABSTRACT A tape cassette recording and/or playback apparatus with a device for changing the drive when a component, comprising a drive member and actuating member, which rotates only during tape transport is stationary. The drive members performs a rotary movement, taking the form of an eccentric, and is adapted to cooperate with a pivotably journalled lever. The lever is connected to the component via a friction coupling, which during rotation of the component exerts a torque on the lever and keeps it positioned against the drive member so that the lever performs a swinging movement when the component rotates and is set to a stationary position by the drive member when the component is stationary. The actuating member performs a periodic movement from which the stop or over operation for the tape drive can be derived by the actuation of a switching device via the actuating member when the lever is in the stationary position. The drive member can be driven by a first wheel and actuating member by a second wheel and the actuating member is constituted by a connecting rod which is eccentrically and pivotably journalled on the second wheel and is articulated to the lever via a coupl- ing rod. The coupling rod transmits the swinging movement of the lever also to the actuating member and in the stationary position of the lever moves the actuating member to a position from which, during its reciprocating movement, it actuates the switching device.
