PURPOSE:To enable to copy and record a part required for copy, by using an image sensor having CdSe-Te photoelectric film as a read-in sensor. CONSTITUTION:As a read-in head, an image sensor having CdSe-Te photoelectric film having a peak of sensitivity in red is used. The frame 9 surrounding the part 8 to be copied for the objective 7 to be copied is marked with an ink having a color high in refrection factor for red color, e.g., red fluorescent paint. This copied objective 7 is scanned toward the arrow with a read-in head, allowing to obtain a signal shown in Figure. Taking scanning distance for x-axis and sensitivity for y- axis, the red level (a) in the marked part is higher in the sensitivity level than the white level (b) of the white paper, allowing to identify the marked part, and economical usage of recording paper and edit operation is made easy. |
