Abstract
Abstract A disc record apparatus having a fixed housing including an entrance slot for a disc record and a surface to slidably receive a disc record inserted edge first in its own plane through said slot to a playing position has a drive spindle for the disc record mounted in a spindle or motor housing for translation axially of the spindle and perpendicularly relative to the plane of the disc record. The spindle is movable in tranlation from an insertion position displaced from the plane of the record to an operative position in engagement centrally with a disc record in playing position for rotating the disc record. A motor driven cam member translates the spindle housing. A movable gate is provided for the entrance slot and the motor driven cam member is connected for opening and closing the gate so that a disc record may be inserted or ejected coordinated with translation movement of the spindle. An ejection mechanism driven from the same motor driven cam member is provided for automatically ejecting the disc record.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
In a disc record apparatus hving a fixed housing including an entrance slot for a disc record and a surface to slidably receive a disc record inserted edge first in its own plane through said slot to a playing position: a drive spindle for a disc record; a spindle housing including a drive motor for said drive spindle; means for mounting said spindle housing on said fixed housing for translation axially of said spindle and perpendicularly relative to said plane from an insertion position displaced from said plane to an operative position with said hub in engagement centrally with a disc record in playing position for rotating the disc record; and motor driven means for translating said spindle housing between said positions.
Claim 2
Dependent Claim
122 words
In a disc record apparatus hving a fixed housing including an entrance slot for a disc record and a surface to slidably receive a disc record inserted edge first in its own plane through said slot to a playing position: a drive spindle for a disc record; a spindle housing including a drive motor for said drive spindle; means for mounting said spindle housing on said fixed housing for translation axially of said spindle and perpendicularly relative to said plane from an insertion position displaced from said plane to an operative position with said hub in engagement centrally with a disc record in playing position for rotating the disc record; and motor driven means for translating said spindle housing between said positions.
Claim 3
Dependent Claim
46 words
A player apparatus according to claim 1 including a movable gate for said entrance slot and motor driven means for opening and closing said gate so that a disc record may be inserted or ejected coordinated with translation movement of said spindle housing between said positions.
Claim 4
Dependent Claim
38 words
A player apparatus according to claim 2 in which said motor driven means for translating said spindle housing and for opening and closing said gate comprises a cam member connected to both said spindle housing and said gate.
Claim 5
Dependent Claim
43 words
A player apparatus according to claim 2 including motor driven means for ejecting a disc record from said playing position through said entrance slot coordinated with translation movement of said spindle housing between said positions and the opening and closing of said gate.
Claim 6
Dependent Claim
28 words
A player apparatus according to claim 4 in which said motor driven means includes a cam member connected to said spindle housing, said gate and said ejecting means.
Claim 7
Dependent Claim
57 words
A player apparatus according to claim 5 in which said motor driven means for ejecting a disc includes a spring loaded plate operated by inward movement of a disc record to compress said resilient means as a disc record is inserted to store energy for assisting the outward movement of the plate for ejecting a disc record.
Claim 8
Dependent Claim
61 words
A player apparatus according to claim 1 in which a spring loaded stop is pivotally mounted on said fixed housing, two flexible members are mounted on said fixed housing to engage the periphery of an inserted disc record, said flexible members cooperating with said stop to define a stable intermediate position of the inserted disc record partially inserted through said slot.
Claim 9
Dependent Claim
32 words
A player apparatus according to claim 1 in which said motor driven means for translating said spindle housing includes a rotatable cam member and a cam follower connected to said spindle housing.
Claim 10
Dependent Claim
52 words
A player apparatus according to claim 1 in which said fixed housing includes a horizontal surface for slidably receiving a disc record, and a cylinder extending downwardly from said horizontal surface for mounting said spindle housing for translation axially of said spindle and perpendicular relative to a disc record in playing position.
