Abstract:
PURPOSE:To compact an image scanner by arranging a CCD linear image sensor on an image pickup plate for receiving light transmitted through a half mirror and a CCD linear image sensor on an image pickup plate for receiving the reflected light on mutually shifted positions and reading out an original on respective end positions. CONSTITUTION:Straight transmitted light is received and read out by the CCD linear image sensor 11 on the image pickup plate 10. On the other hand, the reflected light from the half mirror 8 is received and read out by the CCD linear image sensor 13 on the image pickup plate 12. Since the image pickup plates 10, 12 are mutually shifted in position, the left half read out by an original reading window 3 is read out by the sensor 11 on the plate 10 for receiving the transmitted light through the half mirror 8 and the right half is read out by the sensor 13 on the plate 12 for receiving the reflected light from the half mirror 8. Thereby, the right end of the sensor 11 on the plate 10 and the left end of the sensor 13 on the plate 12 are continued on the image and the image scanner an be compacted.
