PURPOSE:To obtain stably an original reader with high accuracy by storing respective correction amount of plural lens systems to a memory, referencing data in the memory at reading of an original, and correcting automatically the joints of the plural lens systems, to decrease remarkably the time used for assembling/adjustment. CONSTITUTION:A signal in an A channel line memory 71 and in a B channel line memory 72 are fed to a correction amount detecting circuit 9 by an external switch 8 and each correction amount is stored in a correction amount storage circuit 10. The correction circuit 11 extracts correction amount information a, b stored in the correction amount storage circuit 10 and an a-bit is eliminated from the tail edge of the signal in the A channel line memory 15. A b-bit is eliminated from the front edge of the signal of the B channel line memory 16, they are synthesized by the correction circuit 11 and stored in the line memory 12. |
