Abstract

Abstract An ultra-compact tape cassette system includes an ultra-compact cassette and an adapter, simulating a standard compact cassette, which allows the cassette to be played in a recorder designed for a standard compact cassette. When the cassette is inserted into the adapter, internal reel brakes are automatically de-activated, and the front door of the cassette is opened, to expose the tape for playing. The adapter further comprises devices which simulate recordable tabs and reflect the recordable status of the ultra-compact cassette.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 192 words
An adapter for adapting an ultra-compact cassette to a conventional compact cassette recorder, comprising a housing having a floor bounded by lateral walls and a rear wall, and a hinged door opposite said rear wall, said walls and said door defining a cavity for receiving the ultra-compact cassette, and a cover for partially closing the cavity from above, said cover being hinged to said side walls by respective pivots, a pair of pinions, one fixed to each pivot so that the pinions turn as the cover is moved between its open and closed positions, a pair of rails, movably mounted within the housing along each of said side walls, each of said rails comprising means for engaging said ultra-compact cassette, and each rail having a rack in mesh with a respective one of said pinions whereby the racks move in unison lengthwise as the cover is moved, so that when the cover is closed, the ultra-compact cassette is driven toward the rear of said housing, and further comprising means for engaging the magnetic tape of the ultra-compact cassette and for guiding it along a path adjacent to the door of the adapter.
Claim 2
Dependent Claim 192 words
An adapter for adapting an ultra-compact cassette to a conventional compact cassette recorder, comprising a housing having a floor bounded by lateral walls and a rear wall, and a hinged door opposite said rear wall, said walls and said door defining a cavity for receiving the ultra-compact cassette, and a cover for partially closing the cavity from above, said cover being hinged to said side walls by respective pivots, a pair of pinions, one fixed to each pivot so that the pinions turn as the cover is moved between its open and closed positions, a pair of rails, movably mounted within the housing along each of said side walls, each of said rails comprising means for engaging said ultra-compact cassette, and each rail having a rack in mesh with a respective one of said pinions whereby the racks move in unison lengthwise as the cover is moved, so that when the cover is closed, the ultra-compact cassette is driven toward the rear of said housing, and further comprising means for engaging the magnetic tape of the ultra-compact cassette and for guiding it along a path adjacent to the door of the adapter.
Claim 3
Dependent Claim 19 words
The invention of claim 1, further comprising at least one latch for locking the cover in its closed position.
Claim 4
Dependent Claim 23 words
The invention of claim 1, further comprising mechanical means for indicating the recordable status of the ultra-compact cassette to a conventional compact recorder.
Claim 5
Dependent Claim 107 words
The invention of claim 3, wherein said housing has an opening in its rear wall, and said indicating means comprises a lever mounted within said housing adjacent said opening, said lever being pivotable between a first position indicating that the ultra-compact cassette is recordable, and a second position indicating it is not, said lever having a portion exposed through said opening, and a probe positioned to engage a recordable tab on the ultra-compact cassette, and further comprising a spring for biasing said lever toward said second position, whereby, when an ultra-compact cassette is secured in the adapter, said lever assumes a position indicative of the recordable status.
