Latest Patents

Hoppmanns holds a patent for a loading mechanism for a magnetic tape cassette apparatus. This invention features a holder that allows a cassette to be pushed against an ejection slide into a pushed-in position. A lifting device is employed to move the holder from a position for receiving or ejecting a cassette to an operating position. As the ejection slide is moved to the pushed-in position, a pivoting catch engages the slide to lock it during the movement of the lifting device. Upon reverse movement of the lifting device, a tilting lever engages a lug mounted to the apparatus frame, pivoting to unlock the ejection slide. Additionally, ejection slides on each side of the holder may be interconnected by a rack and pinion arrangement, which includes a brake to slow the rotation of the pinion shaft during ejection.
