  • Patent number: 4006853
    Abstract: A fast forward drive for a cartridge tape player comprises upper and lower crescents which increase the effective capstan diameter in the fast forward mode. At normal playing speed the crescents index with respect to a received tape cartridge such that the capstan's surface forcibly engages the cartridge's pressure roller.When the fast forward mode is desired a clutch couples the upper crescent to the capstan for rotation therewith. Rotational drive of the upper crescent is coupled to the lower crescent, at a predetermined phasing relationship, through a pin and trough arrangement, whereby fast forward is effected. On return to the normal play speed the upper crescent is fixedly indexed, resulting in a decreased lower crescent rotational drive and thus an increased chance of improper lower crescent alignment.

  • Patent number: 3972073
    Abstract: When the ignition switch of the automobile is turned off, a solenoid in the tape player is de-energized and the release of its armature pulls a small resilient roller into contact with the tape drive capstan. The capstan forces the roller into a wedged position with a lever arm which in turn activates a cantilevered eject mechanism to eject a tape cartridge. As the cartridge is pushed away from the capstan, it removes power from the capstan. If an attempt is made to insert a cartridge while the key is still "off", the power to the capstan would be restored and, as before, cause ejection of the cartridge.
