Abstract
Abstract A disk cartridge storage apparatus which can facilitate insertion of a disk cartridge 3 into a stocker 7 while positively preventing the cartridge, once placed at a predetermined storage position, from jutting out or dislodgement. The stocker has a pair of opposite side walls 7a for slidably accommodating the cartridge. The opposite side walls are provided with retaining members 8 for holding the cartridge at the storage position in combination with biasing members 12 for resiliently biasing the retaining members to engage in retaining recesses 3a which are formed in opposite side surfaces of the cartridge, respectively. The retaining member 8 is so constructed that the effort required for inserting the cartridge into the stocker is smaller than that required for withdrawing the cartridge from the stocker.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
123 words
A disk cartridge storage apparatus, comprising: a stocker having a pair of opposite side walls for slidably and removably storing disk cartridges each containing an information recording disk; retaining means provided at the opposite side walls of said stocker for holding a disk cartridge placed within said stocker at a storage position; and biasing means for biasing said retaining means to a retaining position where said retaining means are caused to engage in retaining recesses formed in opposite side surfaces of said disk cartridge, respectively; wherein said retaining means are so constructed that an effort required for inserting said disk cartridge to said storage position within said stocker is smaller than an effort required for taking out said disk cartridge from said stocker.
Claim 2
Dependent Claim
149 words
A disk cartridge storage apparatus according to claim 1, wherein said retaining means includes a plurality of paired retaining members mounted by pivotal portions on the side walls of said stocker so as to be rotatable between said retaining position and an idle position, said retaining members having latch projections formed in inner surfaces of said retaining members facing the side walls of said cartridge, respectively, said latch projections being engageable in retaining recesses formed in opposite side walls of said cartridge, respectively, at said retaining position, said latch projections being arranged such that a drag applied to said cartridge by said retaining means due to the engagement between said latch projections and said retaining recesses, respectively, upon insertion of said cartridge is smaller than a drag applied to said cartridge by said retaining members due to the engagement between said latch projections and said cartridge upon withdrawal thereof.
Claim 3
Dependent Claim
120 words
A disk cartridge storage apparatus according to claim 2, wherein each of side walls of said stocker is provided with a length of vertically extending groove and a plurality of guide grooves extending horizontally from said vertical groove, and wherein each of said retaining members includes said pivotal portion of a cylindrical shape, a flat supporting portion extending from said pivotal portion in a direction orthogonal to the axis thereof, and said latch projection of an arcuate shape projecting from an inner side of said supporting portion, said cylindrical pivotal portion being rotatably fitted in said vertical groove formed in said side wall of said stocker with said supporting portion being slidably fitted in one of said horizontal guide grooves.
Claim 4
Dependent Claim
38 words
A disk cartridge storage apparatus according to claim 3, wherein said supporting portion of said retaining member has an outer side surface formed with a spring holder on which said biasing means including a coil spring is mounted.
Claim 5
Dependent Claim
54 words
A disk cartridge storage apparatus according to claim 3, wherein each of said retaining members further includes a stopper provided at a position to abut against a leading end surface of said cartridge upon insertion of said cartridge to a predetermined position within said stocker, to thereby delimit the storage position of said cartridge.
Claim 6
Dependent Claim
19 words
A disk cartridge storage apparatus substantially as herein described with reference to Figures 1 to 6 of the drawings.
