<p>PURPOSE:To smoothly and securely transfer a disk cartridge between a holder, a storage part and a driver with simple constitution by providing right and left arm turning means, a roller energizing means and a cam device. CONSTITUTION:When a cam 36 is driven, followers 38 and 40 rotate along a cam surface and they approach and are detached. Rollers 31a and 31b a the tips of the arms 33a and 33b are displaced between operation/saving positions and the cam followers 38 and 40 are slightly detached from the cam surfaces 36a and 36b. In the energizing means 45, a spring 45c is given to wires 45a and 45b and it is connected to leaves 47a and 47b through a pully. The, they turn with the shafts 48a and 48b as a center and cam followers 49a and 49b are given to the tips of the levers. When the arms 33 are in the operation position, the rollers 31 are abutted on the side surface of the cartridge C by the operation of the spring 45c, the rollers 31 are turned and feeding is driven. At the time of saving, the cam followers 49a and 49b of the levers 47a and 47b move to the cam surfaces SC, and the expanding ratio of the spring 45c is reduced. Thus, the cartridge transfer of high reliability is attained with such constitution.</p> |
