ABSTRACT:
A compact cassette tape player has a motor drive system which enables a high-fidelity tape player to be made only slightly larger than the cassette being played. The tape player includes a motor which has a flat stator mounted to the player chassis, a motor shaft and a flat motor which is mounted to the motor shaft for rotation relative to the stator. The recorder includes reel pawl hubs or spindles for engaging the tape reels in the cassette. The motor shaft extends into one of the pawl hubs and is mounted in bearings at the ends of the shaft. One of the bearings is located inside the pawl hub so that the bearing mountings for the motor shaft can be spaced as far apart as possible, thus reducing the amount of wow and flutter even though the player is extremely compact. The pawl hub mounting the motor shaft is driven independently of the motor by a drive gear which engages the periphery of a gear wheel secured to the pawl hub. The drive gear is driven by a drive belt which extends from the motor rotor to the player capstan.
