Abstract
A cassette loading device comprises a motor rotatable in a normal direction and in a reverse direction, a driving mechanism for transmitting a power of the motor to a cassette holder and moving the cassette holder, and elastic member mounted on the driving mechanism for generating an elastic force against a depression of a tape cassette when the tape cassette is depressed from an initial position to a cassette-in position. A position detecting device detects that the cassette holder reaches a predetermined position in its moving path and generates a signal, with an initial position detecting device detecting an initial position of the elastic member upon initializing generating a signal. An eject signal generating device generates a signal commanding a cassette unloading, and a micro-processor controls the motor in response to output signals from the position detecting device, the initial position detecting device and the eject signal generating device. The tape cassette is forcibly unloaded irrespective of the elastic force of the elastic member.
