Abstract
A cassette loading apparatus having a cassette holder for holding a tape cassette and driven by a gear train to move the tape cassette to a predetermined loading position includes a pair of gears in engagement with each other in the gear train, at least one of the pair of gears being formed as a geneva stop gear, a locking member provided on one of the pair of gears, and a cam formed on the other gear being in engagement with the locking member. The cam has an increased length, so that when the pair of gears are in engagement the locking member is restricted by the cam and when the pair of gears are disengaged from each other by the geneva stop gear, a rotational ratio substantially equal to a gear ratio of the pair of gears is applied to the pair of gears by the cam and the locking member. In this way when the cassette holder is moved to the loading position the locking member comes in contact with the cam, thereby locking the cassette holder.
