Abstract

PURPOSE:To inform an operator of corrected information on an original position by detecting the original position placed on a platen by providing a light emitting element and a photodetecting element on the platen. CONSTITUTION:When an operator rotates a platen cover 4 from a phantom-line position to a solid-line position by 180 deg., a photodetecting element base 2 also rotates accordingly to the solid-line position by 90 deg.. Then, an original 11 is mounted on a platen 1 and aligned to a stopper 10, so that (n) beams of light generated by light emitting elements 9 are transferred to photodetecting element 8 if they are not cut off by the original 11. Those (n) pieces of optical information are converted into (n)-bit logical level signals to detect the presence of the original 11 in the two outer area and inner area of the platen 1, thus letting the operator know corrected information on the original position.
