<p>PURPOSE:To improve the life of a motor with a reduction in load current on a motor by providing a mechanism which pushes out a cassette holder until a cassette passes an inflection point of a guide groove in the movement thereof from a cassette working position above a reel base to a cassette insertion position. CONSTITUTION:While a cassette and a cassette holder 1 move from a cassette working position to a cassette insertion position, the cassette and the cassette holder 1 rise with a motor with a wiper arm 6 being energized toward left by a down auxiliary lever 8. Moreover, as a boss 5 of the cassette holder 1 passes an inflection point of a slot of a side plate 3, the wiper arm 6 is energized counterclockwise with the down auxiliary lever 8. This achieve a reduction in the load current on the motor at the inflection point thereby improving the life of the motor.</p> |
