Abstract

PURPOSE:To prevent color dislocation from being generated in a recording image by setting the fixed position of respective supporting members so that the relative position of respective reading elements can not be changed when the supporting member to support the respective reading element executes thermal deformation with the change of a temperature. CONSTITUTION:The fixed positions of adjusting boards 4 and 4a, namely, the three numbers of screws 3 and the other three numbers of screws 3a are symmetrically arranged to optical axes I and II of respective lens 8 and 8a respectively. Since the fixed positions of the adjusting boards 4 and 4a are set in this arrangement, the respective fixed positions symmetrically extend and contracts with the optical axes I and II of the lens 8 and 8a as a center when the respective adjusting boards execute thermal extension and contraction by the temperature change. Accordingly, the relative position of CCDs 6 and 6a is not dislocated by the thermal deformation of the adjusting boards 4 and 4a. Samely, even when substrates 5 and 5a of the CCDs 6 and 6a execute the thermal deformation, the relative position of the CCDs 6 and 6a is not changed since the substrates 5 and 5a symmetrically extend to the optical axes I and II.
