ABSTRACT:
An automatic switch-off system for use in a cassette tape recorder. A tape feed shaft is axially supported at one end of an arm lever which has its rotating center at an axis of a relay gear for transmitting the driving power to the tape feed shaft. The tape feed shaft and an encircling hub are moved against the cassette case at the end of tape feeding or rewinding operation by the drawing force of the tape. This movement of the shaft urges the arm lever to release the tape running state by causing a lever to rotate and engage a pin on a pulley which supplies the driving power. This pin causes the lever to move laterally thus permitting a tape running set lever to disengage.
