Abstract
Abstract A record handling mechanism in a disc record playback system includes a record lifting finger which rises through a slot in the turntable to lift a record against a pair of stops located above a set of record receiving pads. The record receiving pads are then retracted out of the way, and the record lifting finger is lowered to a position below the turntable to transfer the record to the turntable. The operating sequence is reversed to restore the record back on the receiving pads.

Claim 1
Independent Claim
240 words
In a record player for recovering prerecorded signals from a disc record supported on a turntable; a record handling apparatus comprising: (A) a stop mounted above a turntable-supported record; (B) a record lifting member having a record engaging portion; (C) means for mounting said record lifting member for movement between a first position where said record engaging portion is disposed below said turntable, and a second position where said record engaging portion extends above said turntable; (D) means for selectively raising and lowering said record engaging portion; the record engaging portion, when raised, engaging the underside of a turntable-supported record to lift said record to a raised position against said stop; (E) a record receiving pad; (F) means for mounting said record receiving pad above said turntable for movement between an advanced position and a retracted position in said advanced position, said record receiving pad being in the path of a record between said turntable-supported position and said raised position; in said retracted position, said record receiving pad being maintained out of said path; and (G) means for selectively advancing and retracting said record receiving pad; wherein to transfer a record from said turntable to said receiving pad, said pad is retracted out of the way of said record, said record lifting member is raised to lift said record above said pad, said pad is advanced, and said record lifting member is lowered to deposit said record on said pad.

In a record player for recovering prerecorded signals from a disc record supported on a turntable; a record handling apparatus comprising: (A) a stop mounted above a turntable-supported record; (B) a record lifting member having a record engaging portion; (C) means for mounting said record lifting member for movement between a first position where said record engaging portion is disposed below said turntable, and a second position where said record engaging portion extends above said turntable; (D) means for selectively raising and lowering said record engaging portion; the record engaging portion, when raised, engaging the underside of a turntable-supported record to lift said record to a raised position against said stop; (E) a record receiving pad; (F) means for mounting said record receiving pad above said turntable for movement between an advanced position and a retracted position in said advanced position, said record receiving pad being in the path of a record between said turntable-supported position and said raised position; in said retracted position, said record receiving pad being maintained out of said path; and (G) means for selectively advancing and retracting said record receiving pad; wherein to transfer a record from said turntable to said receiving pad, said pad is retracted out of the way of said record, said record lifting member is raised to lift said record above said pad, said pad is advanced, and said record lifting member is lowered to deposit said record on said pad.
Claim 3
Dependent Claim
31 words
The apparatus as defined in claim 1 further including a second stop arranged above a turntable-supported record such that said stops are symmetrically disposed in respect of said record lifting member.
Claim 4
Dependent Claim
56 words
The apparatus as defined in claim 1 for use with a record having a prerecorded annular region surrounding a central unrecorded region; wherein said location of said record lifting member is such that said record engaging portion engages a turntable-supported record within said central unrecorded region thereof as said record engaging portion rises above said turntable.
Claim 5
Dependent Claim
45 words
The apparatus as defined in claim 1 for use with a turntable which is at least as large as said record; said turntable having a slot which is located such that said record engaging portion passes through said slot to raise and lower said record.
Claim 6
Dependent Claim
81 words
The apparatus as defined in claim 1 for use with a turntable having a spindle adapted for engagement with the center hold of a record as said record is lowered for placement on said turntable; said apparatus further including a record guide member mounted above said spindle; said record guide member being subject to reception in said record center hole as said record is raised above said turntable spindle, whereby said record is centered in respect of said record receiving pad.
Claim 7
Dependent Claim
33 words
The apparatus as defined in claim 5 further having means for movably mounting said record guide member so that said record can be freed by raising said record guide member above said record.
Claim 8
Dependent Claim
242 words
In a record player for recovering prerecorded signals from a disc record supported on a turntable; a record handling apparatus comprising: (A) a stop mounted above a turntable-supported record; (B) a record lifting member having a record engaging portion; (C) means for mounting said record lifting member for movement between a first position where said record engaging portion is disposed below said turntable, and a second position where said record engaging portion extends above said turntable; (D) means for selectively raising and lowering said record engaging portion; the record engaging portion, when raised, engaging the underside of a turntable-supported record to lift said record to a raised position against said stop; (E) a set of record receiving pads; (F) means for mounting said record receiving pads above said turntable for movement between an advanced position and a retracted position; in said advanced position, said record receiving pads being in the path of a record between said turntable-supported position and said raised position; in said retracted position, said record receiving pads being maintained out of said path; and (G) means for selectively advancing and retracting said record receiving pads; wherein to transfer a record from said turntable to said receiving pads, said pads are retracted out of the way of said record, said record lifting member is raised to lift said record above said pads, said pads are advanced, and said record lifting member is lowered to deposit said record on said pads.
Claim 9
Dependent Claim
242 words
In a record player for recovering prerecorded signals from a disc record supported on a turntable; a record handling apparatus comprising: (A) a stop mounted above a turntable-supported record; (B) a record lifting member having a record engaging portion; (C) means for mounting said record lifting member for movement between a first position where said record engaging portion is disposed below said turntable, and a second position where said record engaging portion extends above said turntable; (D) means for selectively raising and lowering said record engaging portion; the record engaging portion, when raised, engaging the underside of a turntable-supported record to lift said record to a raised position against said stop; (E) a set of record receiving pads; (F) means for mounting said record receiving pads above said turntable for movement between an advanced position and a retracted position; in said advanced position, said record receiving pads being in the path of a record between said turntable-supported position and said raised position; in said retracted position, said record receiving pads being maintained out of said path; and (G) means for selectively advancing and retracting said record receiving pads; wherein to transfer a record from said turntable to said receiving pads, said pads are retracted out of the way of said record, said record lifting member is raised to lift said record above said pads, said pads are advanced, and said record lifting member is lowered to deposit said record on said pads.
