ABSTRACT:
In a tape cassette recording and/or reproducing apparatus capable of selective operation with a relatively large or small-sized cassette containing a respective pair of rotatable reels having a relatively large or small center-to-center distance, respectively; a cassette holder is movable between a cassette receiving and discharging position and a loading position and can receive a selected one of the large and small-sized cassettes when in the receiving and discharging position and can convey the selected cassette to the loading position; a pair of reel bases are movable relative to each other for varying the center-to-center distance therebetween; a reel base adjusting device is selectively driven in first or second modes for respectively moving the reel bases to first or second positions wherein the center-to-center distance therebetween is suitable for engagement with the reels of a large or small-sized cassette; a detector detects the size of a cassette received in the holder and assumes different conditions when detecting the large and small-sized cassettes, respectively; and a drive member is movable with the holder at least part of the way from the receiving and discharging position toward the loading position and is responsive to the condition of the detector for selectively driving the reel base adjusting device in the first and second modes, respectively, so as to dispose the reel bases in positions suitable for the size cassette being conveyed by the holder to the loading position.
