Abstract

Abstract A paper-feeding device(3b,105) which is substantially comprised of a paper-feeding cassette(C3,C8) removably loaded into an image processing apparatus(1,101), locking means (70,114) inhibitting extraction of the paper-feeding cassette(C3,C8) by eagaging itself with the cassette(C3,C8) or the cassette mount(61,113), and locking control means (80,116) activating operation of the locking means (70,114) while paper-feeding operation is underway. Since the locking control means (80,116) remains activated while the paper-feeding operation is underway, the operator cannot extract the paper-feeding cassette(C3,C8) from the image processing apparatus(1) throughout the paper-feeding operation. (Fig. 3)

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 59 words
A paper-feeding device comprising; a paper-feeding cassette which can removably be loaded into an image processing apparatus; locking means preventing said paper-feeding cassette from being drawn out of said image processing apparatus by engaging itself with either said paper-feeding cas­sette or a paper-feeding cassette mount; and locking-control means which is operating said lock­ing means while paper-feeding operation is underway.
Claim 2
Dependent Claim 59 words
A paper-feeding device comprising; a paper-feeding cassette which can removably be loaded into an image processing apparatus; locking means preventing said paper-feeding cassette from being drawn out of said image processing apparatus by engaging itself with either said paper-feeding cas­sette or a paper-feeding cassette mount; and locking-control means which is operating said lock­ing means while paper-feeding operation is underway.
Claim 3
Dependent Claim 23 words
A paper-feeding device according to claim 1, wherein said paper-feeding cassette is extracted in the direction 90 degrees apart from the paper-conveying direction.
Claim 4
Dependent Claim 56 words
A paper-feeding device according to claim 1, wherein said locking means comprises a stopper inhibiting extraction of said paper-feeding cassette by allowing said locking means to be engaged with either said paper-­feeding cassette or said cassette mount, and an engaging member secured to either said paper-feeding cassette or said cassette mount for engagement with said stopper.
Claim 5
Dependent Claim 29 words
A paper-feeding device according to claim 1, wherein said locking-control means activates the opera­tion of said locking means when the copying paper jams up itself in a paper-feeding path.
Claim 6
Dependent Claim 46 words
A paper-feeding device according to claim 4, wherein said locking-control means activates the opera­tion of said locking means when the copying paper does not pass through the predetermined position during a specific period of time from the startup of the paper delivery from. said paper-feeding cassette.
Claim 7
Dependent Claim 31 words
A paper-feeding device according to claim 4, wherein said locking-control means releases said locking means from operative condition by either opening or clos­ing a predetermined cover of said image processing apparatus.
Claim 8
Dependent Claim 22 words
A paper-feeding device according to claim 1, wherein said paper-feeding cassette is substantially an insertion tray of a duplex image processing apparatus.
Claim 9
Dependent Claim 68 words
A paper-feeding device according to claim 1, wherein an objective member to be detected is installed to a tip surface of said paper-feeding cassette or said cassette mount, and in addition, said image processing apparatus is provided with a detecting device detecting the presence of said objective member when said cassette or said cassette mount is fully inserted into a predeter­mined position inside of said image processing apparatus.
Claim 10
Dependent Claim 65 words
A paper-feeding device according to claim 1, wherein a detecting device is installed to a tip surface of said paper-feeding cassette or said cassette mount, and in addition said image processing apparatus is pro­vided with an objective member to be detected by said detecting device when said cassette or said cassette mount is fully inserted into a predetermined position inside of said image processing apparatus.
