ABSTRACT:
A cassette-receiving door device for a cassette tape recorder in which, when a cassette has been correctly loaded in a receiving section, the door device is automatically closed. Correct positioning of the cassette in the receiving device is detected by a pair of switches, which may be implemented with light-emitting elements and phototransistors, positioned at opposite sides of the lower end of the receiving section. If the outputs from both switches indicate that the cassette has been correctly received, a motor is actuated which, through a gear and slider mechanism, closes the cassette-receiving door device.
