Abstract

Abstract An inserting and retrieving mechanism (4) of a "Juke Box" type disc memory device includes a movable body which has pushing members adapted to push a cartridge into a stocker or a recording and reproducing device (3) of the disc memory device and a pair of clampers (40) adapted to pull out the cartridge from the stocker or recording and reproducing device in association with engaging recesses formed on the cartridge (1), a driving means (66) for opening and closing the clampers (40) through a toggle means (77) arranged symmetrically about the driving means (44), a first position sensor (64) provided on the inserting and retrieving mechanism (4) for detecting a position of a rear end of the cartridge (1) when it reaches a position in which the clampers (40) are ready to clamp the cartridge (1) and a second position sensor (65) provided in the stocker (2) and/or the recording and reproducing device (3) for detecting a position of a front end of the cartridge (1) when it reaches a position in which the cartridge (1) is ready to be released. The inserting and retrieving mechanism (4) may have a pair of cartridge holding portions so that a pair of cartridges (1) are to be handled, simultaneously.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 223 words
A disc memory including at least one stocker (2) for storing a plurality of cartridges (1) each having on both sides thereof engaging recesses (2a), at least one recording and reproducing device (3) for recording information on a disc contained in said cartridge (1) and/or reproducing the information, an inserting and retrieving mechanism (4) for retrieving said cartridges (1) from said stocker (2) and inserting said cartridges (1) into said recording and reproducing device (3) or vice versa and a transportation mechanism for transporting said inserting and retrieving mechanism (4) between said stocker (2) and said recording and reproducing device (3) and a reversing mechanism for reversing said inserting and retrieving mechanism (4), comprising a movable body (29) provided on said inserting and retrieving mechanism (4) movably therealong, said movable body (29) having a pushing member (76) and a pair of clampers (40), said pushing member (76) being adapted to push a rear surface of said cartridge (1) into said stocker (2) or said recording and reproducing device (3) when said cartridge (1) is inserted into said stocker (2) or said recording and reproducing device (3), said clampers (40) being adapted to engage at one end thereof with said engaging recesses of said cartridge (1) and to pull out said cartridge (1) from said stocker (2) or said recording and reproducing device (3).
Claim 2
Dependent Claim 223 words
A disc memory including at least one stocker (2) for storing a plurality of cartridges (1) each having on both sides thereof engaging recesses (2a), at least one recording and reproducing device (3) for recording information on a disc contained in said cartridge (1) and/or reproducing the information, an inserting and retrieving mechanism (4) for retrieving said cartridges (1) from said stocker (2) and inserting said cartridges (1) into said recording and reproducing device (3) or vice versa and a transportation mechanism for transporting said inserting and retrieving mechanism (4) between said stocker (2) and said recording and reproducing device (3) and a reversing mechanism for reversing said inserting and retrieving mechanism (4), comprising a movable body (29) provided on said inserting and retrieving mechanism (4) movably therealong, said movable body (29) having a pushing member (76) and a pair of clampers (40), said pushing member (76) being adapted to push a rear surface of said cartridge (1) into said stocker (2) or said recording and reproducing device (3) when said cartridge (1) is inserted into said stocker (2) or said recording and reproducing device (3), said clampers (40) being adapted to engage at one end thereof with said engaging recesses of said cartridge (1) and to pull out said cartridge (1) from said stocker (2) or said recording and reproducing device (3).
Claim 3
Dependent Claim 52 words
The disc memory device as claimed in claim 1, wherein said clampers are supported pivotably by said movable body through fulcrum pins, respectively, and mutual­ly connected pivotably by a toggle means and wherein said toggle means is driven by a driving means to open and close said one ends of said clampers.
Claim 4
Dependent Claim 144 words
The disc memory device as claimed in claim 2, wherein said driving means is a swing lever swingeably supported by said movable body and wherein said toggle means comprises a pair of connecting members having one ends supported by said swing lever rotatably and symmetrically about a swing center of said swing lever, a pair of pivotable clampers supported pivotably by said movable body and having one ends formed with engaging portions, respectively, and the other ends connected rotatably to said swing lever such that said clampers are swinged to open and close said one ends thereof when said swing lever is swinged and such that, when said one ends of said clampers are closed, said the other ends of said clampers, said one ends of said connecting members are on straight lines each passing through said swing center of said swing lever, respectivly.
Claim 5
Dependent Claim 98 words
The disc memory device as clamed in claim 2, wherein said toggle means includes a pair of hinged connect­ing members having one ends connected rotatably to said the other ends of said clampers and said driving means comprises a solenoid means associated with a plunger and a return spring, an end of said plunger being engaged with said hinged portion of said toggle means such that, when said solenoid is actuated, said toggle means is toggled to open said clampers and, when said solenoid is deenergized, said plunger is returned by said return spring to close said clampers.
Claim 6
Dependent Claim 19 words
The disc memory device as claimed in claim 3, wherein each of said connecting members are regulatable in length.
Claim 7
Dependent Claim 79 words
The disc memory device as claimed in any of claims 1 to 5, further comprising a first position sensor provided on said inserting and retrieving mechanism for detecting a position of a rear end of said cartridge in which said clampers are ready to clamp said cartridge and a second position sensor provided in said stocker for detecting a position of a front end of said cartridge in which said cartridge is ready to be released from said clampers.
Claim 8
Dependent Claim 62 words
The disc memory device as claimed in any of claims 1 to 5, further comprising a cartridge feeding and discharg­ing mechanism for supplying and discharing said cartridges into and from said disc memory device and wherein said inserting and retrieving mechanism has a pair of cartridge holding portions so that a pair of cartridges are to be retrieved, transported and inserted, simultaneously.
Claim 9
Dependent Claim 58 words
The disc memory device as claimed in claim 6, further comprising a cartridge feeding and discharging mechanism for supplying and discharging said cartridges into and from said disc memory device and wherein said inserting ans retrieving mechanism has a pair of cartridge holding portions so that a pair of cartridges are to be retrieved, transported and inserted, simultaneously.
