Abstract
Abstract A magnetic disc recorder is provided with an edge loading carriage having provisions to receive and locate a disc cassette relative to a drive hub. The carriage is movable between a loading position where cassette may be inserted or removed, and a playing position where the drive hub engages a complementary hub in the cassette and a transducer interfaces with the record disc in the cassette. The carriage includes a latch retaining the cassette in the operating position, and an ejector functioning to unload the cassette partially in the loading position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
175 words
A cassette type disc magnetic recorder comprising a housing, a motor having a drive hub rotatable about a predetermined aXis in said housing, a carriage movably mounted in said housing between a playing position adjacent said hub and a loading position spaced from said hub, said carriage having a cavity including guide means to receive and to position a cassette containing a magnetic record disc with a driven hub for engagement with said drive hub in said playing position, a transducer mounted in said housing adjacent the playing position of said carriage to interface with a recording disc in a cassette received in said guide means, said carriage being adapted in said loading position to receive a cassette into said guide means of said carriage, a latch on said carriage arranged to engage the cassette in the playing position and to index the cassette for proper alignment of the hubs and of said transducer with respect to the record disc, and actuator means for moving said carriage between the loading position and the playing position.
Claim 2
Dependent Claim
175 words
A cassette type disc magnetic recorder comprising a housing, a motor having a drive hub rotatable about a predetermined aXis in said housing, a carriage movably mounted in said housing between a playing position adjacent said hub and a loading position spaced from said hub, said carriage having a cavity including guide means to receive and to position a cassette containing a magnetic record disc with a driven hub for engagement with said drive hub in said playing position, a transducer mounted in said housing adjacent the playing position of said carriage to interface with a recording disc in a cassette received in said guide means, said carriage being adapted in said loading position to receive a cassette into said guide means of said carriage, a latch on said carriage arranged to engage the cassette in the playing position and to index the cassette for proper alignment of the hubs and of said transducer with respect to the record disc, and actuator means for moving said carriage between the loading position and the playing position.
Claim 3
Dependent Claim
30 words
A recorder as defined in claim 1, including a hinge connected between said housing and said carriage to define the motion of said carriage between the loading and playing positions.
Claim 4
Dependent Claim
204 words
A cassette type disc magnetic recorder comprising a housing including a support plate, a motor mounted on said plate and having a drive hub rotatable about a predetermined axis, a carriage movably mounted in said housing between a playing position adjacent said hub and a loading position spaced from said hub, said carriage having guide means to receive and to position a cassette containing a magnetic record disc with a driven hub for engagement with said drive hub in said playing position, a loading opening in said housing located at one end of said carriage in said loading position to pass a cassette into said guide means of said carriage, actuator means attached to said carriage for moving it between the loading position and the playing position, a transducer mounted in said housing adjacent the playing position of said carriage to interface with a recording disc in a cassette received in said guide means, an ejector in said carriage operative against a cassette received in said guide means tending to hold the cassette partially out of said loading opening in the loading position of said carriage, and retainer mechanism cooperating with said carriage to locate a cassette in said carriage at the playing position.
Claim 5
Dependent Claim
204 words
A cassette type disc magnetic recorder comprising a housing including a support plate, a motor mounted on said plate and having a drive hub rotatable about a predetermined axis, a carriage movably mounted in said housing between a playing position adjacent said hub and a loading position spaced from said hub, said carriage having guide means to receive and to position a cassette containing a magnetic record disc with a driven hub for engagement with said drive hub in said playing position, a loading opening in said housing located at one end of said carriage in said loading position to pass a cassette into said guide means of said carriage, actuator means attached to said carriage for moving it between the loading position and the playing position, a transducer mounted in said housing adjacent the playing position of said carriage to interface with a recording disc in a cassette received in said guide means, an ejector in said carriage operative against a cassette received in said guide means tending to hold the cassette partially out of said loading opening in the loading position of said carriage, and retainer mechanism cooperating with said carriage to locate a cassette in said carriage at the playing position.
Claim 6
Dependent Claim
78 words
A recorder as defined in claim 3 wherein said drive hub is supported in a fixed position with its axis of rotation generally intersecting the center of said carriage, a hinge connected between said housing and the other end of said carriage opposite said loading opening whereby said carriage swings about said hinge between its loading and playing positions, and said actuator means including an arm attached to said carriage and extending to the exterior of said housing.
Claim 7
Dependent Claim
32 words
A recorder as defined in claim 3, including spring means urging said carriage to the loading position, and said actuator means including a latch to retain said carriage in the playing position.
