US4165069A — Copier having removable paper feed module

Claim 1

Independent Claim 118 words

In a copier having cut-sheet-supply/sheet-feeding means operable to separate a border sheet from a stack and to feed the separated sheet for use in a copy process to make copies therefrom, the improvement comprising: a frame member supporting the copier's copy process components, including said cut-sheet-supply/sheet-feeding means, in an operative copy process relationship; and movable mounting means connecting said cut-sheet-supply/sheet-feeding means to said frame such that said feeding means is movable between copier-operative and copier-inoperative positions; said copier-operative position facilitating sheet feeding into said copier for use in said copy process to produce copies on said sheets; and said copier-inoperative position facilitating copier maintenance by sheet feeding while said feeding means is removed from the remaining copier components.

Claim 2

Dependent Claim 118 words

In a copier having cut-sheet-supply/sheet-feeding means operable to separate a border sheet from a stack and to feed the separated sheet for use in a copy process to make copies therefrom, the improvement comprising: a frame member supporting the copier's copy process components, including said cut-sheet-supply/sheet-feeding means, in an operative copy process relationship; and movable mounting means connecting said cut-sheet-supply/sheet-feeding means to said frame such that said feeding means is movable between copier-operative and copier-inoperative positions; said copier-operative position facilitating sheet feeding into said copier for use in said copy process to produce copies on said sheets; and said copier-inoperative position facilitating copier maintenance by sheet feeding while said feeding means is removed from the remaining copier components.

Claim 3

Dependent Claim 20 words

The copier defined in claim 1 including means operable to position and secure said feeding means in said copier-operative position.

Claim 4

Dependent Claim 33 words

The copier defined in claim 2 wherein said feeding means includes electrically energizable motive means, and electrical connection means connecting said motive means to said copier in both said copier-operative and copier-inoperative positions.

Claim 5

Dependent Claim 46 words

The copier defined in claim 3 wherein said feeding means includes at least one vertically movable sheet stack elevator, and at least one sheet picking means cooperating with the top sheet of said stack, said elevator and sheet picking means being powered by said motive means.

Claim 6

Dependent Claim 139 words

In a transfer-type electrophotographic copier having at least one cut sheet supply bin operable to supply copy paper and a sheet path operable to receive and align sheets supplied from said bin prior to being supplied to said transfer station for use in the copy process; the improvement comprising: a movable frame mounting said supply bin; paper feeding means for said supply bin mounted on said frame in cooperating relation with paper within said bin; electrical motive means mounted on said frame and coupled to drive said feeding means; and means movably mounting said frame to said copier in a first copier-operative position whereat said paper feeding means is operable to feed sheets to said sheet path, and a second copier-inoperative position whereat said paper feeding means is operable to feed sheets exterior of said copier during copier maintenance.

Claim 7

Dependent Claim 139 words

In a transfer-type electrophotographic copier having at least one cut sheet supply bin operable to supply copy paper and a sheet path operable to receive and align sheets supplied from said bin prior to being supplied to said transfer station for use in the copy process; the improvement comprising: a movable frame mounting said supply bin; paper feeding means for said supply bin mounted on said frame in cooperating relation with paper within said bin; electrical motive means mounted on said frame and coupled to drive said feeding means; and means movably mounting said frame to said copier in a first copier-operative position whereat said paper feeding means is operable to feed sheets to said sheet path, and a second copier-inoperative position whereat said paper feeding means is operable to feed sheets exterior of said copier during copier maintenance.

Claim 8

Dependent Claim 30 words

The copier defined in claim 5 wherein said bin includes a movable paper stack supporting platform, and electrical motive means mounted on said frame and coupled to move said platform.

Claim 9

Dependent Claim 50 words

The copier defined in claim 5 wherein said supply bin includes a generally horizontal, movable platform adapted to vertically support a stack of sheets, with the top sheet thereof in operative relation to said paper feeding means, and electrical motive means mounted on said frame to vertically position said platform.

Claim 10

Dependent Claim 55 words

The copier defined in claim 7 including a second cut sheet supply bin mounted on said movable frame in vertical alignment with said one sheet supply bin, a second movable paper stack supporting platform for said second supply bin, and second electrical motive means mounted on said frame and coupled to drive said second platform.

Claim 11

Dependent Claim 19 words

The copier defined in claim 8 wherein said sheet path includes a sheet aligner upstream of said transfer station.
