Abstract

A cassette type package, mountable in a machine has a removable protective cover which cooperates with interlocking mechanisms such that the cover cannot be removed from the cassette when the cassette is not in the machine and the cassette cannot be removed from the machine unless the cover is in the cassette. The interlocking mechanism includes a pair of hooks or catches, one attached to the machine for preventing removal of the cassette from the machine when the cover is removed and the other fixed to the cassette for holding the cover in the cassette, except when deactuated by a trigger device mounted on the machine.

Latch Mechanism

A cassette type package, mountable in a machine has a removable protective cover which cooperates with interlocking mechanisms such that the cover cannot be removed from the cassette when the cassette is not in the machine and the cassette cannot be removed from the machine unless the cover is in the cassette. The interlocking mechanism includes a pair of hooks or catches, one attached to the machine for preventing removal of the cassette from the machine when the cover is removed and the other fixed to the cassette for holding the cover in the cassette, except when deactuated by a trigger device mounted on the machine.

The cassette and associated latching mechanisms are shown and described in association with a small magnetic disk file but modifications for a variety of particular applications will be apparent. The machine for receiving cassette 10 is not shown other than the components attached to it which cooperate with cassette 10 and its cover 11. The cassette 10 with protective cover 11 inserted is shown at A as it would be outside of the machine. Two plates joined at handle 12 in a U-shaped configuration form the protective covers 11 for disk file 10 which is loosely mounted within 10 so that it can operate with other mechanisms within the machine. At B, cover 11 is shown removed which normally can be affected only when 10 is in the machine. Hook 16 is spring mounted to the frame of 10 and retains 11 within 10 as is shown by the dotted position at E.
