ABSTRACT:
In the optical character reading apparatus having an upper unit, lower unit, and discharge unit, the upper unit and discharge unit are swingably connected to the lower unit at its pivot. In case where paper jamming or the like occurs during a read operation, the upper unit is swung to expose the conveying path. In transportation of the apparatus, the discharge unit is swung to cover the upper unit. Further, desired characters and the like are printed on the processed documents to easily classify them.
