Abstract:
1. A sheet take-out apparatus comprising: a supply mechanism to move sheets in a stacked state to a take-out position where the sheets are moved in the forefront in turn; at least one take-out roller which contacts a forefront sheet in the stacked state and rotates to take out the forefront sheet moved to the take-out position; a pressing mechanism which presses the at least one take-out roller against the forefront sheet at the take-out position constantly at a fixed pressure; at least one pressure sensor to detect a contact pressure of the at least one take-out roller to contact the forefront sheet at the take-out position, and wherein the pressing mechanism includes: wherein the at least one motor driver is controlled in response to the contact pressure detected by the at least one pressure sensor; wherein the supply mechanism includes a stacker to stack at least the forefront sheet and a second sheet in an erected state, and wherein the at least one take-out roller includes a lower roller arranged in contact with a lower portion of the forefront sheet in the stacker and an upper roller arranged in contact with an upper portion of the forefront sheet, to take-out the forefront sheet in a horizontal direction by rotating the lower and upper rollers, wherein, the apparatus further comprises: a floor belt supporting the forefront and second sheets stacked in the stacker by contacting the lower ends of the forefront and second sheets; a first moving mechanism to move the forefront and second sheets toward the at least one take-out roller by running the floor belt; a backup plate that contacts an upper portion of the second sheet stacked in the stacker; and a second moving mechanism to move the forefront and second sheets toward the at least one take-out roller by moving the backup plate, wherein the pressing mechanism includes:
