Abstract
PURPOSE:To shorten the time for discharging of original and improve working efficiency by backward feeding the original with a backward running mechanism after measurement of the transmittance of the original and discharging the same through an insertion part. CONSTITUTION:When only the original O is inserted into an insertion port, a detecting switch SW1 turns on, and the original is fed forward by a forward-backward running belt 3, and enters a transmittance detector 11. When the original O enters the detector 11, a signal goes to a microcomputer, thereby announcing the incoming of the original. Then, the microcomputer stores the data from the detector 11 into an RAM. Upon ending of this process, a forward-backward running clutch 6 changes over to backward running, thereby running the belt 3 backward and returning the original O to the insertion port. Thereby, the transmittance of the original is measured with good efficiency.
