Abstract
A control apparatus for controlling a microcassette tape transport of one motor type includes a first designation means (106) for designating a constant speed transport mode, a rewind mode, and a fast forward mode; a second designation means (124) for designation a direction of the motor rotation; a third designating means (122) for designating a direction of the tape transport. In order to effect the control of a tape transport on the basis of the combination of designations by the first, second and third designation means, the apparatus further includes a first memory means (301) which operates, e.g. when the operation mode shifts from the constant speed transport mode to the rewind mode, and is used when a direction of the motor rotation is switched; a second memory means (401) which operates from the detection of the tape end until the motor stops and reverses its direction of the rotation, and provides a signal of the tape end detection; a third memory means (601) which operates when the operation mode shifts from the constant speed transport mode to the rewind mode or when it is returned from the rewind mode to the constant speed transport mode, and is used to distinguish bet…
