Abstract
A tape player is provided to simplify a mechanical part, eliminate parts, and provide efficient assembly of the mechanical part and a more compact apparatus. The tape player includes pins respectively moving in four different grooves provided in one disk-like cam, and a lever in conjunction with the movement of the pins to use movement of the lever so as to perform a cassette tape carry in/out operation, a head base moving operation, a playback running direction switching operation, and a selective operation to transfer driving force to a reel rest during fast forward.
Claims6
A tape player comprising:
- a first slide plate sliding under guidance from a movable pin engaging a first groove provided in a disk-shaped cam for a cassette tape carry in/out operation;
- a second slide plate resiliently connected to the first slide plate through an elastic body to follow the sliding of the first slide plate;
- a slider for holding a cassette tape, said slider movable in an opposite direction to the sliding;
- a detecting lever detecting an engaged position of the second slide plate with respect to the detecting lever for a cassette tape carry-in operation;
- and
- a switch for actuating a motor, the detecting lever adapted to activate the switch to carry in the cassette tape in response to the detection of the engaged position of the slide plate,
- wherein when both the first and second slide plates are moved to predetermined positions the detecting lever is biased to return from the engaged position to an original position apart from the second slide plate.
A tape player, comprising:
- a rotatable cam;
- at least one slidable plate interacting with the rotatable cam and capable of performing a sliding movement controlled by a relative rotational position of the rotatable cam with respect to at least one of the at least one slidable plate;
- a detecting lever detecting a defined rotational position of the rotatable cam associated with a cassette tape carry-in operation;
- a motor for carrying in a cassette tape;
- and
- a switch for actuating the motor in response to the detection of the defined rotational position;
- wherein at least one of the at least one slidable plate has a notch for engaging the detecting lever for the defined rotational position.
