Abstract
Abstract A device for mounting a copy sheet cassette on a copy sheet feed tray pivotally supported at its lower end by the copying apparatus for movement between a copy sheet feed position and a cassette mounting position. The device is effective to move, when the copy sheet feed tray is in the cassette mounting position, the copy sheet feed roller and corner separator means in positions in which they do not interfere with the mounting of the cassette on the copy sheet feed tray.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
194 words
A copy sheet cassette mounting device for a copying machine, comprising a copy sheet feed tray having a lower end and pivotally connected at said lower end thereof to an immovable member secured to the copying machine for removably mounting a copy sheet cassette thereon, support means secured to the copying machine for moving said copy sheet feed tray between a copy sheet feed position and a cassette mounting position, cassette positioning means provided on said copy sheet feed tray for correctly positioning the cassette with an upper end thereof as a reference in mounting the same on the copy sheet feed tray, a cover for the copy sheet feed tray operatively connected thereto, a copy sheet feed roller for supplying one copy sheet after another from the cassette mounted on the copy sheet feed tray, corner separator means provided on the copy sheet feed tray, and means for moving said copy sheet feed roller and said corner separator means to an inoperative position to facilitate mounting of the cassette on the copy sheet feed tray when said cover is opened and the copy sheet feed tray is moved to its cassette mounting position.
Claim 2
Dependent Claim
194 words
A copy sheet cassette mounting device for a copying machine, comprising a copy sheet feed tray having a lower end and pivotally connected at said lower end thereof to an immovable member secured to the copying machine for removably mounting a copy sheet cassette thereon, support means secured to the copying machine for moving said copy sheet feed tray between a copy sheet feed position and a cassette mounting position, cassette positioning means provided on said copy sheet feed tray for correctly positioning the cassette with an upper end thereof as a reference in mounting the same on the copy sheet feed tray, a cover for the copy sheet feed tray operatively connected thereto, a copy sheet feed roller for supplying one copy sheet after another from the cassette mounted on the copy sheet feed tray, corner separator means provided on the copy sheet feed tray, and means for moving said copy sheet feed roller and said corner separator means to an inoperative position to facilitate mounting of the cassette on the copy sheet feed tray when said cover is opened and the copy sheet feed tray is moved to its cassette mounting position.
Claim 3
Dependent Claim
25 words
A device according to claim 1 wherein said cassette positioning means comprises a projection formed at an upper end of the copy sheet feed tray.
Claim 4
Dependent Claim
37 words
A device according to claim 1 wherein said cover is operatively connected to said copy sheet feed tray through a link mechanism for causing the copy sheet feed tray and the cover to move as a unit.
Claim 5
Dependent Claim
281 words
A copying machine comprising an enclosure having a side wall with a side facing opening therein, a cover pivotally mounted at its lower end to said enclosure and moveable pivotally between a closed position in which it is flush with said side wall and closes the opening therein and an open position in which the upper end of the cover extends outwardly and awaY from said side wall, a copy sheet feed tray for removably mounting a copy sheet cassette, said feed tray having a lower end pivotally secured to the enclosure to pivot about an axis parallel to that of the cover and disposed inwardly of said side wall, an upper end having an upwardly extending projection adapted to register with a corresponding aperture in a cassette mounted on the feed tray, and corner separator means, means for linking the feed tray and the cover to cause the feed tray to pivot to a mounting position in which its upper end points outwardly of said side wall and protrudes through said opening therein when the cover is manually moved to its open position, and to pivot to a copy sheet feed position in which the feed tray is inwardly of said side wall when the cover is manually moved to its closed position, said feed tray leaning toward the cover when in its feed position, and said linking means including means for gravity biasing the feed tray and the cover toward their feed and closed positions respectively when the cover is manually closed, and means for feeding sheets from a cassette mounted on said feed tray, said feeding means operative only when the feed tray is in its feed position.
Claim 6
Dependent Claim
281 words
A copying machine comprising an enclosure having a side wall with a side facing opening therein, a cover pivotally mounted at its lower end to said enclosure and moveable pivotally between a closed position in which it is flush with said side wall and closes the opening therein and an open position in which the upper end of the cover extends outwardly and awaY from said side wall, a copy sheet feed tray for removably mounting a copy sheet cassette, said feed tray having a lower end pivotally secured to the enclosure to pivot about an axis parallel to that of the cover and disposed inwardly of said side wall, an upper end having an upwardly extending projection adapted to register with a corresponding aperture in a cassette mounted on the feed tray, and corner separator means, means for linking the feed tray and the cover to cause the feed tray to pivot to a mounting position in which its upper end points outwardly of said side wall and protrudes through said opening therein when the cover is manually moved to its open position, and to pivot to a copy sheet feed position in which the feed tray is inwardly of said side wall when the cover is manually moved to its closed position, said feed tray leaning toward the cover when in its feed position, and said linking means including means for gravity biasing the feed tray and the cover toward their feed and closed positions respectively when the cover is manually closed, and means for feeding sheets from a cassette mounted on said feed tray, said feeding means operative only when the feed tray is in its feed position.
