ABSTRACT This invention relates to a mode change-over mechanism for a tape recorder, in particular for the rapid feed mode and rewind mode of a tape recorder. The device of this invention decreases the number of parts hitherto needed for switching the motor and rolls, and moreover ensures reliable mesh- ing between the gears, thus overcoming slipping problems associated with con- ventional mechanisms. The present mechanism has a feeder reel and take-up reel which have gear elements at their respective peripheral surfaces. A rapid feed gear meshes with the gear element relating to the take-up reel, and a rewind gear meshes with the rapid feed gear and with the gear element at the periphery of the feeder reel. The rapid feed gears are connected to a drive motor and when moving, rotate to connect with the gear element of the take-up reel. The rewind gear, when moving, connects with both the rapid feed gear and the gear element of the feeder reel. This co-action achieves posi- tioning of the rapid feed gear and rewind gear.
