Abstract

PURPOSE:To enable high-quality control by transmitting a correcting amount to a conveying means, positioning a medium after temporarily conveying it backward, next conveying it forward and conveying the above-mentioned medium while positioning it when conveying the medium backward. CONSTITUTION:According to the designated moving amount of forward conveyance, a conveying means 1 converts the moving amount to the unit moving amount of a driving mechanism and conveys the medium. A conveyance correcting means 6 transmits the correcting amount after calculating a value to minimize the physical moving amounts of forward and backward positioning means 4 and 5 for the movement to the position designated by the backward conveyance. In this case, when the conveying means 1 detects the designation of the backward conveyance, the conveyance correcting means 6 uses the physical moving amount stored in a storing means 3. Thus, in the case of conveying the medium backward, this medium is temporarily conveyed backward, positioned, next conveyed forward and positioned so as to convey this medium.
