<P>PROBLEM TO BE SOLVED: To prevent positional shift in recording pixels by setting the spacing of a plurality of linear light sources based on the respective exposure time of the linear light sources in an exposure apparatus. <P>SOLUTION: Linear light sources having a plurality of light emitting elements arrayed in a direction approximately perpendicular to the moving direction of a photosensitive recording material are arranged in n rows (n is an integer of 2 or more) in the moving direction of the photosensitive recording material, and the linear light sources are controlled to sequentially emit light to record in recording pixels. When the light emission order in the linear light sources is in the same direction as the moving direction of the photosensitive recording material, a distance L<SB>i</SB>between centers of adjacent linear light sources is controlled to satisfy L<SB>i</SB>=äk<SB>i</SB>+(1/2)×(t<SB>i</SB>+t<SB>i+1</SB>)/T}×P with respect to the distance P between centers of the recording pixels, wherein i represents an integer in the range of 1≤i≤n-1, k<SB>i</SB>is an integer 1 or more, t<SB>i</SB>is an exposure period in the linear light source of the i-th row, and T represents Σt<SB>i+1</SB>. When the light emission order of the linear light sources is opposite to the moving direction of the photosensitive recording material, Li is controlled to satisfy L<SB>i</SB>=äk<SB>i</SB>-(1/2)×(t<SB>i</SB>+t<SB>i+1</SB>)/T}×P. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
