Abstract

PURPOSE:To achieve detection of tape stop accurately, by the constitution that revolution is always obtained from a turntable at a winding side through the movement of a switching member in which two pinch rollers can selectively be press-contacted on two capstans. CONSTITUTION:When tape end or winding stop takes place from a tape running state, a cam wheel 31b of the 2nd rotating body 31 succeedingly rotates, but since a friction rotating plate 24 stops, after a pin 28 enters a cam groove 24a and the plate 24 is located at a neutral location, the plate is butted to a projection 24b and no further movement caused. Thus, by a rest stroke of a rocking member 25 of the cam wheel 31b, the member is moved toward the arrow E against a spring 27 by taking a contact section between the pin 28 and the projection 24b of the cam groove as a fulcrum and a rocking fulcrum 25b of the member 25 is moved, allowing to move an operating member 33 toward the arrow E and to close a contact 59. Thus, the friction rotating plate 24 is brought into contact with winding side at forward/reverse any revolution to detect stopping accurately.
