Abstract
PURPOSE: To increase the sheet processing speed without spoiling the resolution, by subscanning in the longitudinal direction of a mark which has been put on the sheet, and also increasing the subscanning speed so that size of the picture element recognized by the line sensor can be lengthened in the subscanning direction.
CONSTITUTION: The sheet 1 on which the mark information has been recorded is set in the direction which marks the longitudinal direction of the mark parallel with the subscanning direction, and the sheet is conveyed by the rubber roller 2. The encoder 3 coupled directly with the rubber roller 2 rotates the rubber roller 2, at the same time outputs a signal showing the sheet conveying amount, operates the pulse counter 4, and conveyance of the sheet 1 reaches the prescribed amount. Namely, when the pulse count number has reached the prescribed value, scanning of the line sensor 5 is started. On the other hand, the reflected ray of the mark information recorded on the sheet is focused by the condenser 6, it is made incident to the line sensor 5. When the subscanning pitch in the conveying direction of the picture element is made larger than the main scanning pitch, the sheet conveying speed can be increased without deteriorating the resolution.
