Abstract:
An auto-reverse mechanism in a cassette tape recorder comprising:a main body plate having a groove for slidably receiving a select lever with a projection;a motor rotatable in opposite directions, the motor being mounted on the main body plate;a flywheel driven by the motor in opposite directions to rotate a capstan in opposite directions, the flywheel being concentric to the capstan;a head base supporting a pinch roller and a pair of magnetic heads at opposite sides of the pinch roller, the head base having a hole that accommodates the capstan and a forked guide hole that receives the projection of the select lever, the forked guide hole having a pair of inclined guide grooves with one end of the inclined guide grooves connected to each other;a head selector including a rotary plate rotatable with the flywheel, the rotary plate being engaged with the select lever in a tape stopped state,wherein, when the flywheel rotates, the rotary plate rotates to move the select lever within the groove of the main body plate in the same direction as rotation of the rotary plate and releases the select lever after movement for a predetermined distance, so as to move the projection into a selected one of the inclined guide grooves of the forked guide hole; anda head base lift that lifts the head base in a direction determined by the selected one of the inclined guide grooves, thereby moving the pinch roller toward the capstan and moving a selected one of the magnetic heads, which corresponds to the selected one of the inclined guide grooves, toward a tape surface.
