ABSTRACT:
A sheet supply/conveyance mechanism for sheets includes a hopper for accommodating a stack of plural sheets, a conveyer for picking up the sheets from the hopper and conveying the sheets in an advancing direction along a path, two detectors for optically detecting a leading edge of a sheet being conveyed, a correcting device for correcting the horizontal alignment of the sheet in accordance with the detection results of said detectors, and right and left guide plates provided in the hopper for aligning the respective, opposite sides of the stacked sheets. The guide plates are slidable in a horizontal direction perpendicular to the sheet advancing direction. The guide plates are respectively connected with the two detectors, so that the detectors are also slidable in the horizontal direction, together with the respective guide plates.
