ABSTRACT:
A tape end detector for reel driven cassette tape recorders includes a drive gear which is driven by a motor, a transmission gear which normally transmits the rotation of the drive gear to a take-up gear associated with a tape take-up shaft but which revolves around the drive gear to detect a tape end being reached whenever the take-up gear ceases to rotate when a terminal end of a tape being taken up is reached, and a support arm for supporting the transmission gear and adapted to be driven angularly by the revolution of the transmission gear to achieve an auto-shutoff operation of the tape recorder.
