Abstract

A stack of disk cartridges 10 are sequentially fed singly from the top of the stack to an operating position 11 and thereafter to a stacker 12. When a stack of disk cartridges is placed in hopper 13, a feed cycle places a single disk in the operating position. During subsequent loading cycles, the disk in operating position 11 is ejected to stacker 12 and the next subsequent disk from hopper 13 is delivered to operating position 11.

Stack Feed Autoloader

A stack of disk cartridges 10 are sequentially fed singly from the top of the stack to an operating position 11 and thereafter to a stacker 12. When a stack of disk cartridges is placed in hopper 13, a feed cycle places a single disk in the operating position. During subsequent loading cycles, the disk in operating position 11 is ejected to stacker 12 and the next subsequent disk from hopper 13 is delivered to operating position 11.

When a loading cycle is initiated, a motor, not shown, is actuated to drive cams 14 and 15 through a single revolution. Initially, door cam 14 acting through link 17 and bell crank 18, causes door 19 to pivot from the solid line closed position to the broken line open position. Door 19 and bell crank 18 are pivotally interconnected about pin 20.

Thereafter, link 22 is permitted to move to the left from the broken line position to the solid line position, as cam follower 23 follows sweeper cam 15. During this motion, latch 24 which pivots about pin 25 is moved clockwise as the depending projection 26 of link 22 engages pin 27. This rotation of latch 24 releases spring loaded catapult 28 to pivot upward, propelling the disk cartridge in operating position 11 upward. The disk cartridge follows the surface of deflector plate 30 and falls into stacker 12. Simultaneously, sweeper arm 31 is moved from the broken line position to the solid line position about the axis of pin
33.

The subsequent rise of sweeper cam 15 caus...
