ABSTRACT:
The apparatus is used for the automatic sequential handling of floppy disks and includes a disk writing and reading unit, a loading stacker and a receiving stacker. A single disk can be inserted in the top part of the unit, whereas a pack of disks is placed in the loading stacker. A plate dividing the loading stacker from the receiving stacker can be moved to bring the bottom part of the unit into communication with the loading stacker and the receiving stacker alternately.
The disks are inserted one after another into the bottom part of the unit by a moving slider when the latter is shifted from left to right and the plate is lowered. A feeding tooth detaches the disk at the bottom of the pack and positions it with respect to the slider.
During the right-to-left return movement of the slider, the plate is raised and a pair of pincers mounted on the slider withdraws the written or read disk from the bottom part of the unit, and lets it fall into the receiving stacker.
