ABSTRACT:
A recording and reproducing apparatus for magnetic discs, each one contained in a protective case (23), comprises a frame (11) having a front slot (20) for the insertion of a case (23). The disc case (23) slides into a support unit (30) spaced above a driving hub (81) and a magnetic head (90) mounted on a carriage (91). The support unit (30) is urged downardly by springs (37) but is held in the raised position by pins (32, 33) trapped in slots (54) of tongues (50 to 53) upstanding from a slider (45). The disc case engages a lever (70) which turns clockwise and engages a lever (61) to turn this also clockwise. The lever (61) disengages from an edge of the slider (45) which moves forwardly under the action of a spring (48) to free the pins (32, 33) and allow the support unit (30) to drop down vertically, guided by the pins (32, 33) in vertical slots (34, 35). The lever (70) may additionally push a cover of the disc case laterally to uncover slots (24) in the disc case. To remove the disc case (23) the slider (45) is pushed back by a button (49) and the tongues (50 to 53) cam the pins (32, 33) upwardly again, while springs biasing the lever (61 and 70) reset these levers and eject the disc case (23) out from the apparatus.
