3 is a sectional view taken along the - line in FIG. 1, FIG. 4 is a sectional view taken along the - line in FIG. 3, FIG. 5 is a sectional view taken along the - line in FIG. 7 is a sectional view taken along the - line in FIG. 3, FIG. 8 is a sectional view taken along the - line in FIG. FIG. 11 is a perspective view of an exposure slit tube, FIG. 11 is a partially enlarged view of the present apparatus showing how developing paper is fed, and FIG. 12 is a schematic diagram of a conventional sheet feeding device. In the figure, 80 is a guide plate (the lower guide plate in the figure corresponds to the sliding surface), 80a is a convex portion corresponding to the blocking means, 82 is a stopper, and 84 is a feed roller corresponding to the second roller. , 85 is a pinch roller corresponding to the first roller, 87 is a support tube corresponding to the lifting means, and 96 is a driving gear corresponding to the driving means.

Claims

[Claims for Utility Model Registration] A sliding surface on which a sheet slides, a first roller provided above the sliding surface at a predetermined distance from the sliding surface, and a first roller provided below the first roller. a second roller; a driving means for rotating at least one of the first roller and the second roller; and a driving means provided on the sliding surface downstream of the first roller and the second roller, and a leading end of the sheet to be fed. A stopper made of a step or a protrusion that comes into contact with the stopper to stop its feeding, and a second roller that is movably supported, and by raising the second roller, the leading edge of the sheet that is in contact with the stopper is lifted. In the sheet feeding device, the sheet feeding device includes a lifting device that releases contact with a stopper and presses and biases the second roller against the first roller, the sheet feeding device being provided upstream of the first roller and the second roller. and a blocking means for preventing the sheet from being lifted higher than a predetermined position when the second roller is raised.
