Abstract
Abstract A disc file apparatus which holds a cartridge (1) at both surfaces thereof through a slit formed from an open end to a closed end of a bill-like-shaped cartridge holder (28), clamps by clampers (53) the cartridge (1) at both lateral sides thereof, and renders the axis of rotation of a pick-up and discharge mechanism (4) shifted from the center of gravity thereof so as to regulate rotation of the cartridge holder (28) by a stopper (78) in a range of an angle of 180° , whereby when the cartridge (1) is turned over or even when the same is subjected to an impact from the exterior, the cartridge is reliably held so that there is no fear that the rotational position thereof is shifted. The disc file apparatus uses linear ball bearing at each movable part and makes stand-by the utmost end of the clamper as close as possible to a stocker (2) or a recording and reproducing system (3), thereby improving the processing speed as a whole, and furthermore temporarily makes stand-by the cartridge (1) discharged from the recording and reproducing system just above an insertion and discharge port thereof by a transfer mechanism, thereby enabling a processing time to be reduced when a plurality of cartridges are continuously fed to the recording and reproducing system.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
311 words
A disc file apparatus which is provided with; at least one of stockers housing in juxtaposition a plurality of cartridges each housing therein an information storage medium and having at both sides surfaces recessed engaging portions respectively; at least one of recording and reproducing systems each disposed in such a manner that a first direction of taking or housing said cartridge out of or into said stocker is parallel to the direction of inserting or discharging said cartridge into or from said recording and reproducing system, thereby reading or recording the information from said storage medium; a carriage moving by being guided along rails extending in a second direction of juxtaposing said cartridges in said stocker; and pick-up and discharge means for said cartridge, which has a cartridge holder to hold said cartridge, moves said cartridge holder in the first direction so as to pick-up said cartridge from said stocker, inserts said cartridge into an insertion/discharge port of said recording and reproducing system, reversely takes out said cartridge discharged from said recording and reproducing system, and houses said cartridge into said stocker at a predetermined position therein, has a function for turning over said cartridge, and is supported to said carriage; said pick-up and discharge means being provided with; a cartridge holder which is provided at one end with an opening and formed at the other end in a bill-like shape, said opening being opposite to the front surface of said cartridge housed in said stocker, said closed end being supported by said carriage in relation of being rotatable around the axis parallel to the first direction; a moving member movable in parallel to the first direction between said opening and said closed end at said cartridge holder; and a clamping mechanism mounted on said moving member and engageable with said engaging portion at said car tridge, thereby clamping said cartridge.
Claim 2
Dependent Claim
311 words
A disc file apparatus which is provided with; at least one of stockers housing in juxtaposition a plurality of cartridges each housing therein an information storage medium and having at both sides surfaces recessed engaging portions respectively; at least one of recording and reproducing systems each disposed in such a manner that a first direction of taking or housing said cartridge out of or into said stocker is parallel to the direction of inserting or discharging said cartridge into or from said recording and reproducing system, thereby reading or recording the information from said storage medium; a carriage moving by being guided along rails extending in a second direction of juxtaposing said cartridges in said stocker; and pick-up and discharge means for said cartridge, which has a cartridge holder to hold said cartridge, moves said cartridge holder in the first direction so as to pick-up said cartridge from said stocker, inserts said cartridge into an insertion/discharge port of said recording and reproducing system, reversely takes out said cartridge discharged from said recording and reproducing system, and houses said cartridge into said stocker at a predetermined position therein, has a function for turning over said cartridge, and is supported to said carriage; said pick-up and discharge means being provided with; a cartridge holder which is provided at one end with an opening and formed at the other end in a bill-like shape, said opening being opposite to the front surface of said cartridge housed in said stocker, said closed end being supported by said carriage in relation of being rotatable around the axis parallel to the first direction; a moving member movable in parallel to the first direction between said opening and said closed end at said cartridge holder; and a clamping mechanism mounted on said moving member and engageable with said engaging portion at said car tridge, thereby clamping said cartridge.
Claim 3
Dependent Claim
66 words
A disc file apparatus according to Claim 1, wherein said moving member has a first guide which is open at the utmost end thereof slightly larger than a thickness of said cartridge in order to guide one end thereof opposite to said pick-up and discharge means, and said cartridge holder having at an opening thereof second guides formed of elastic member for holding therebetween said cartridge.
Claim 4
Dependent Claim
73 words
A disc file apparatus according to Claim 1, wherein said moving member has a guide open at the utmost end thereof slightly larger than a thickness of said cartridge so as to guide one end thereof opposite to said pick-up and discharge means, and said cartridge holder has a slit of width slightly larger than a thickness of said cartridge and guides said cartridge lengthwise thereof through said slit and holds said cartridge.
Claim 5
Dependent Claim
25 words
A disc file apparatus according to Claim 1, wherein said cartridge holder is supported by said pick-up and discharge means through a cross roller bearing.
Claim 6
Dependent Claim
43 words
A disc file apparatus according to Claim 4, wherein said rail has a convex shape in cross section and has a lengthwise groove at both sides slopes of said convex shape, and said carriage having guide means for moving itself along said groove.
Claim 7
Dependent Claim
60 words
A disc file apparatus according to Claim 5, wherein said guide means comprises; sliders each projecting at part thereof so as to opposite to said groove at said rail and provided with an annular circulating route; and a plurality of balls movable on said circulating route, at least one of said balls always abutting against said groove at said rail.
Claim 8
Dependent Claim
