PURPOSE:To raise a resolution by a titled device which is small-sized, simple and inexpensive without requiring each adjustment of a lens position by dividing a linear image of an original picture onto plural CCD image sensor arrays, and projecting it by a magnification of one to one. CONSTITUTION:A long size type rod lens array 401-1 and 401-2 having an effective length equal to a scanning width of an original picture are inclined by an angle theta to each other against a perpendicular line of an original picture 406, placed in parallel to a scanning line 400, and an image 402-1 and 402-2 are formed by projecting the scanning line 400 in the respective directions. As for a long size type rod array 401, generally, (m) pieces are provided. Each sensor 403-1, 403-2 of a CCD array sensor group placed so that the photodetecting surfasce coincides with the image 402-1 and 402-2 photodetects by dividing alternately by a part each of a linear scanning line image. Each CCD array sensor 403-1, 403-2 takes a partial charge of a section of a length L/n which has divided a scanning width L into (n) equal parts. A resolution to the original picture 406 can be made almost equal to a resolution of the CCD array sensors 403-1, 403-2.
