Abstract
Abstract A card cassette includes a card containing chamber, and a card feeding roller located on the wall of at least one side of the card containing chamber. When the cassette is inserted into a cassette mount or a cassette receiving recess of a mating device, the roller rolls on the inner wall of the cassette receiving recess of the device as the cassette is further pushed inward, thereby automatically delivering the card within the card containing chamber into a card processing station of the device. When the card cassette is withdrawn from the cassette receiving recess of the device, the roller rolls in the reverse direction, thereby automatically restoring the card into the chamber.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
239 words
A card cassette for use with a cassette mount having an interior wall enclosing a cassette receiving chamber, comprising a case having interior walls defining a card containing chamber for containing a card that is to be used to record information and to play back information therefrom, a card access opening communicating with said card containing chamber, said walls having a feed roller mounting slot, a feed roller rotatably mounted on said walls and extending within the feed roller mounting slot, bias means urging the card feed roller in an outward direction away from any card within the card receiving chamber into a position at which at least a part of its periphery projects through the slot and exteriorly of said cassette, said feed roller being brought into abutment against the interior walls of the cassette mount when introduced therein to be forced inwardly against said bias means into engagement with the card within said card containing chamber, said feed roller being rollable on the interior walls of the cassette mount as the cassette is further inserted therein to rotate the said feed roller in a forward feed direction and thereby deliver the card further within the cassette receiving chamber, said feed roller being rollable on the interior walls of the cassette mount in an opposite direction when the cassette is withdrawn from the cassette mount to thereby return the card into the card-receiving chamber of said cassette mount.
Claim 2
Dependent Claim
239 words
A card cassette for use with a cassette mount having an interior wall enclosing a cassette receiving chamber, comprising a case having interior walls defining a card containing chamber for containing a card that is to be used to record information and to play back information therefrom, a card access opening communicating with said card containing chamber, said walls having a feed roller mounting slot, a feed roller rotatably mounted on said walls and extending within the feed roller mounting slot, bias means urging the card feed roller in an outward direction away from any card within the card receiving chamber into a position at which at least a part of its periphery projects through the slot and exteriorly of said cassette, said feed roller being brought into abutment against the interior walls of the cassette mount when introduced therein to be forced inwardly against said bias means into engagement with the card within said card containing chamber, said feed roller being rollable on the interior walls of the cassette mount as the cassette is further inserted therein to rotate the said feed roller in a forward feed direction and thereby deliver the card further within the cassette receiving chamber, said feed roller being rollable on the interior walls of the cassette mount in an opposite direction when the cassette is withdrawn from the cassette mount to thereby return the card into the card-receiving chamber of said cassette mount.
