ABSTRACT:
A control mechanism for floppy disk drive units. A single control rod having cam lobes is mounted with an operating end extending through the front bezel of the unit. The control rod has a lobe cooperating with surfaces to establish positive loaded and unloaded positions of the driving cone and spindle of the unit. The driving cone is carried from an arm having an actuating spring cooperating with a lobe of the control rod. The actuating spring has angular detent parts whereby the control rod moves with a snap action between loaded and unloaded positions of the cone. The control rod has a further cam lobe carrying a pressure pad which comes into contact with the diskette in the loaded position along with an arm dropped or loaded with the head.
