<p>PURPOSE:To minimize the wear by providing a shifting member to shift recording media and an accommodating body where the recording media are accommodated and a guide member to guide the shifting of the shifting member on the plane and forming the part specified by the parabola, at a part of the guide member. CONSTITUTION:When a cassette is loaded, a door 3 is opened and the cassette is inserted into a case 8. When the door 3 is turned in the upper direction with a shaft 4 as a fulcrum, a link 11 guided to a pin 14 pressures the case 8 through a pin 10 in the rear direction of an enclosure 1. Consequently, pins 9 and 10 are guided respectively to guide holes 6 and 7, and the case 8 shifts the cassette from the position in the front upper direction to the position in the rear lower direction. At such a time, to close the door 3, the force to add the energizing force and the friction force of a spring 15 is necessary, two guide holes 6 and 7 are regulated respectively by the parabola on the plane of a plate 5, and then, the loss due to the friction can be decreased.</p> |
