A front loading cassette tape latching, loading and unloading device comprises a base seat, a cassette sliding plate, cassette clamping arms, cassette damping rollers, a cassette spring plate, cassette guide seats, a button sliding plate and a button sliding plate agraffe. When the cassette tape is being pushed into the machine, it will move the cassette sliding plate and trigger the button sliding plate agraffe to force the button sliding plate out, and further allow the cassette clamping arms to rotate. Rotation of the clamping arms forces the cassette clamping rollers to clamp the cassette and to latch the cassette tape on the guide seat. When removing the cassette, the button sliding plate is pushed to open the clamping rollers, and the cassette will spring out of the machine by the force of the cassette sliding plate. This compact cassette loading and unloading arrangement is easy to assemble and cost effective to produce.

Cassette loading and unloading device

An improved structure for use in a tape driving device for driving a tape contained in a cartridge. The improved structure comprises (a) a first slide plate having a plurality of first slideways received by first horizontal grooves, so as to allow the first slide plate to reciprocate on vertical guide pins, the first slide plate being slidable in a direction parallel to the direction in which a cartridge is inserted; (b) a second slide plate having a plurality of second slideways received by second horizontal grooves so as to allow the second slide plate to reciprocate on the vertical guide pins, the second slide plate being slidable in a direction parallel to the direction in which the cartridge is inserted; (c) a main driving wheel and a motor mounted on the first slide plate; (d) an idle wheel mounted on the second plate; and (e) a spring connecting between the first slide plate and the base plate; (f) wherein the idle wheel, the main driving wheel, and the spring are positioned such that when the cartridge is inserted into the slot, the spring will be tensiled thus causing the main driving wheel to be in contact with the idle wheel, and the idle wheel in contact with a driving wheel provided in the cartridge, whereby a frictional force between the idle wheel and the driving wheel will cause a tape traveling therebetween to move as a result of a rotation by the main driving wheel.
