Original reader

Abstract

Abstract PURPOSE:To exactly correct the read signal of original information by feeding a blank sheet to an adhering sensor prior to the reading of the original information, and detecting the data of a blank output on the blank sheet with the adhering sensor. CONSTITUTION:Prior to the reading of the original information, a sheet supplying means 7 feeds a blank sheet 5 to an adhering sensor 2, and the adhering sensor 2 detects the blank output on the blank sheet. Therefore, the dispersion data of a blank output waveform can be calculated. Thus, shading correction is attained and since the blank sheet 5 is moved from the adhering sensor 5 by being taken-up with the sheet supplying means 7 in the case of reading the original information, the blank sheet 5 is prevented from being stained by an original.
