<p>PURPOSE:To correct positively the skew delivering, by composing a skew delivering element of a chip containing a plurality of bits, processing the digital signals from the chip, and driving and controlling DC motors for rotating intermediate delivering rollers positioned at opposite sides of a sheet. CONSTITUTION:The DC motors 1 are respectively connected to the pair of the intermediate delivering rollers 12 positioned at opposite sides of the sheet P that is delivered along a delivering path 11 of a copying machine by a papering roller 10, etc., and the skew delivering detecting element 15 is arranged in the delivering path 11 and adjacent to the intermediate delivering rollers 12. The detecting element 15 comprises optical fibers having a pattern of 8 columns and 8 rows that are arranged in a plane along which the sheet will be traveled, each row can have output of 8 bits, and the outputs are sent to an MPU (not shown). The MPU detects the skew of the sheet P, and according to the detected result, each of the DC motors 1 is driven and controlled to correct the skew delivering.</p> |
