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.
Claims8
In a diskette drive assembly having a chassis frame and a channel to receive the diskette having a central opening, means including a driving spindle and drive cone cooperating with the spindle, the improvements comprising means mounting the drive cone for vertical movement relative to the chassis frame, control rod means mounted over the chassis frame and having an end extending from the front of the chassis frame, means for moving the driving cone relative to the spindle having loaded and unloaded positions, the said last means having a part engageable with the said control rod for movement between the loaded and unloaded position said part including an elongated actuation spring in a position normal to the said rod and having and end portion connected to the driving cone, said control rod having a lobe positioned to be engageable with said actuation spring, the said actuation spring having formations in it engageable with said lobe of the driving rod which establish loaded and unloaded positions of the driving cone.
