Abstract
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.
