Abstract
An improved control device for use in an automatic video tape cassette changing apparatus is adaptive to various types of the video cassette recorders. The control device is capable of sequentially changing a plurality of cassettes in a convenient and reliable manner in a video cassette recorder. The control device include the sensors 52, 53, 54, 55, 56, the microprocessor 51 and the drive circuit for actuating the mechanical components. The microprocessor includes a first control mode responsive to the cassette detection signals from the sensor 54 and 56 for sequentially actuating the drive circuits 21, 36 and 39, and a second control mode responsive to the cassette detection signals from the sensors 53 and 56 for sequentially actuating the drive circuits 36, 39 and 41.
