Claims

[Scope of Claim for Utility Model Registration] 1. A copy paper loading section into which stacked sheets of copy paper are loaded, a copy paper supply mechanism disposed in the copy paper loading section,
In a copy paper supply device comprising: a paper feed auxiliary mechanism disposed in the copy paper loading section and acting on the uppermost sheet of copy paper in a stack of sheets; the paper feed auxiliary mechanism; includes a pair of auxiliary rollers that act on the sheet-like copy paper located at the uppermost position, and each of the pair of auxiliary rollers is movable in the lateral direction of the copy paper loading section. Copy paper supply device. 2. A copy paper cassette containing stacked sheets of copy paper is removably installed in the copy paper loading section, and each of the pair of auxiliary rollers is moved in the lateral direction in relation to the copy paper cassette. A copy paper feeding device according to claim 1, which is movable. 3. Each of the pair of auxiliary rollers is composed of a substantially conical roller, and on the other hand, a roller moving cam is disposed at a predetermined interval on the copy paper cassette, and the copy paper cassette is moved between the copy paper cassette and the copy paper. When removably attached to the loading station, each of the roller movement cams acts on the auxiliary roller to position the auxiliary roller at a predetermined position relative to the copy paper cassette;
A copy paper supply device according to claim 2 of the utility model registration claim. 4. The copy paper supply device according to claim 3, wherein the roller moving cam is constituted by a width regulating plate disposed at a predetermined interval on the copy paper cassette. 5. The copy paper supply mechanism includes a rotary shaft that is rotationally driven and a paper feed roller attached to the rotary shaft, and each of the pair of auxiliary rollers is mounted on the rotary shaft so as to be movable in the axial direction thereof. The copy paper supply device according to any one of claims 2 to 4, which is rotatably mounted. 6. The paper feeding auxiliary mechanism further includes a pinion that is rotationally driven by an electric motor, and a pair of rollers that are movably arranged in the lateral direction and have a rack that engages with the pinion. each of the auxiliary rollers is rotatably attached to the roller positioning member, and when the copy paper cassette is detachably attached to the copy paper loading section,
3. The copy paper feeding device according to claim 2, wherein the electric motor is actuated in relation to the copy paper cassette, and the auxiliary roller is thus positioned at a predetermined position relative to the copy paper cassette. 7. The paper feeding auxiliary mechanism further includes a positioning shaft rotationally driven by an electric motor, and one side of the positioning shaft has a spiral guide groove in a predetermined direction in which one of the auxiliary rollers is positioned. A spiral guide groove is formed on the other side in a direction opposite to the predetermined direction in which the other auxiliary roller is positioned, and when the copy paper cassette is removably attached to the copy paper loading section. , wherein the electric motor is operated and controlled in relation to the copy paper cassette, and the auxiliary roller is thus positioned at a predetermined position relative to the copy machine cassette.
