<p>PURPOSE:To simplify a mechanism and to reduce in size. CONSTITUTION:Pins 10, 11 are engaged with one of a pair of cam grooves 18, 19 while bringing a cassette into contact with a case positioning unit 8 of a cassette holder 6 in a state that a motor 28 is stopped to be pressed against a tensile strength of a coiled spring 27 together with a cam plate 12. After the motor 28 is driven, a rack plate 22 is driven by the motor to slide the plate 12 via a coupling part 20-25 of the rack plate to the plate 12. The holder 6 is moved by a pair of cam groove 18, 19 of the cam plate and a pair of guide grooves 4, 5 of a mechanical chassis 1 to load a cassette 7.</p> |
