    摘要: A mode control ring having cams for operating various devices in a cassette tape recorder is rotatably mounted on a base plate. A normal pinch device and a reverse pinch device are mounted on the base plate. Each of the pinch devices comprises a capstan, a pinch roller provided on a swing lever so as to be engaged with the capstan, and an idler provided to be engaged with a reel gear. A power transmitting devices is provided for transmitting a driving power from a motor to each capstan. The normal pinch device, reverse pinch device are disposed along the circumference of the mode control ring, and each swing lever is arranged so as to be moved in the radial direction of the mode control ring. Selective operation of these devices is controlled by the rotatably mounted mode control ring, which has various cams formed on its inner peripheral surface, on its outer surface, and as grooves therein, which are engaged with cam following members of the devices.
