摘要： A casing (10) has a front slot (20) for insertion of a disc in its case (23). The disc case slides into a support (30) spaced above a driving hub and magnetic head (90) on a carriage (91). The support (30) is urged downwardly by springs (37) but is held in the raised position by pins (32, 33) trapped in slots in tongues (50to 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 slots (34, 35). The lever (70) may additionally push a cover on the disc case laterally to uncover slots (24) in the disc case. To remove the disc the slider (45) is pushed back by a button (49) and the posts (50 to 53) cam the pins (32, 33) upwardly again, while springs biasing the levers (61 and 70) reset these levers and eject the disc case.
