Abstract
A cassette loading device for a recording and/or reproducing apparatus, capable of loading tape cassettes of different sizes and weights, comprises a cassette holder capable of moving between a cassette insertion position and a cassette loading completed position, cassette holder driving means, optical sensors for detecting which type of tape cassette has been inserted into the recording and/or reproducing apparatus, and torque control means for controlling the driving torque of the cassette holder driving means in response to a detection signal indicative of the type of tape cassette, thereby allowing the tape cassette to load at an essentially consistent loading speed regardless of the type of tape cassette. With this construction, the loading device has high positioning accuracy.
