Abstract
Abstract A record load-unload device has a curved guide device which engages the periphery of a record being inserted into and removed from said load-unload device. A friction drive member engages the edge of the record, and a drive device moves the record along the guide device for inserting and removing a record into and out of the load-unload device.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
In a record load-unload device having a guide device for engaging the rim of a record being inserted into and removed from said load-unload device, an improvement wherein said guide device is a curved member having a grooved surface for engaging the periphery of a record being inserted into and removed from said load-unload device; a friction drive member for engaging the edge of said record, and drive means for driving said friction drive member, said friction drive member being positioned diametrically opposite to the entry to said guide device whereby rotation of said drive member moves said record along said guide device for inserting and removing a record into and out of said load-unload device.
Claim 2
Dependent Claim
116 words
In a record load-unload device having a guide device for engaging the rim of a record being inserted into and removed from said load-unload device, an improvement wherein said guide device is a curved member having a grooved surface for engaging the periphery of a record being inserted into and removed from said load-unload device; a friction drive member for engaging the edge of said record, and drive means for driving said friction drive member, said friction drive member being positioned diametrically opposite to the entry to said guide device whereby rotation of said drive member moves said record along said guide device for inserting and removing a record into and out of said load-unload device.
Claim 3
Dependent Claim
29 words
The device of claim 1 wherein the distal end of said guide device includes an offset portion for permitting a record to be raised out of said guide device.
Claim 4
Dependent Claim
27 words
The device of claim 1 wherein the axis of rotation of said drive means and of said friction drive member is movable with respect to said record.
Claim 5
Dependent Claim
55 words
The device of claim 3 further including a pinion mounted on the shaft of said drive means, and a stationary curved rack engaging said pinion, said drive means being mounted on a plate pivotable about an axis whereby said drive means pivots about said axis when said record is fully inserted into said load-unload device.
Claim 6
Dependent Claim
74 words
The device of claim 4 further including a pivotable lifting lever having a wedge-shaped end, said lever being pivoted by said drive means when said drive means pivots about said axis; a drive mechanism including a turntable arranged in the proximity of said wedge-shaped end, said drive mechanism being pivotably mounted whereby pivoting of said lifting lever engages said wedge-shaped end with said drive mechanism and brings said turntable into engagement with said record.
Claim 7
Dependent Claim
36 words
The device of claim 1 wherein the loading of a record into said load-unload device engages said record with said guide device and said friction wheel to slightly turn said motor to generate a start pulse.
Claim 8
Dependent Claim
21 words
The device of claim 1 further including a mechanical stop for limiting the insertion of said record into said load-unload device.
