Abstract
A tape apparatus autostop mechanism including a head base for setting a driving apparatus in an operational mode; a lock plate that locks the head base at an operational position in response to movement of the head base; a sensor, attached coaxially to a fast forward gear always rotatable in synchronism with a reel base, following the fast forward gear under contact friction with the fast forward gear, the sensor being urged in a rotational direction of the fast forward gear by the contact friction with the fast forward gear; a swingable reset arm urged in one direction by torque of the sensor while the fast forward gear is rotating in right or left directions; a forward gear having an inner and an outer cam, for transmitting force to the reel base; a swingable reset arm arranged to contact the inner and outer cams and rotatably supported; and a reset spring that presses a kick arm, attached to the reset arm, against the inner and outer cams, whereby when the torque of the sensor disappears as the reel base stops, pressing force of the reset arm against the kick arm via the reset spring also disappears, a cam follower of the kick arm stays apart from the inner cam, the fast forward…
