Abstract
A machine operative to sequentially pull jacketed flexible magnetic disk units (which may be termed 'diskettes') into a data transferring position, close a collet on a disk driving spindle for clamping the disk onto the spindle for drivingly rotating the disk from the spindle and move magnetic heads into contact with the disk for a data transferring action. The machine includes a clothespin like picker or gripping device reciprocative so as to move into embracing relationship with the diskette and to then pull the diskette into data transferring position. The diskettes are contained in a magazine which is translatable transversely with respect to the path of travel of the picker device so that the picker device may be operative to grip any one of the series of diskettes, depending on the translated position of the magazine. The picker device is driven from an electrical stepping motor driving a pulley which in turn drives a belt operatively connected with the picker device, and the pulley carries a pair of cams one of which is effective on a swing arm for moving the collet into engagement with the driving spindle and the other of which is effective on a swing arm for causing engagement of the magnetic heads with the disk for a data transferring action.
