IPC: H04N1/00
Filed: 1989-12-13
Abstract: PURPOSE:To exactly feed the tip of an original to an original read position without being affected by the thickness of the original or dispersion between constituting parts, etc., by calculating an amount to move the original between first and second sensors and applying the calculated amount to an original moving amount setting means, which sets the original moving amount from the second sensor to the original read position, as a correction value. CONSTITUTION:The amount to move an original 1 between first and second sensors 4 and 5 is calculated by a step counter 11 and a step number control circuit 13 and based on the calculated moving amount, it is fed back to the original moving amount from the second sensor 5 to an original read position 2 and corrected. Based on the corrected original moving amount, a pulse motor 3 is rotated by a pulse motor control circuit 12 so that the tip of an original 1 can be fed to the original read position 2. Thus, without being affected by the thickness of the original 1 or the dispersion between the constituting parts, etc., the tip of the original 1 is correctly fed to the original read position 2.
