<p>PROBLEM TO BE SOLVED: To provide an optical write device for a large breadth size which is constituted long as a whole by arranging a plurality of light-emitting element array units each including a relatively short printed board, in a longitudinal direction in which light-emitting element arrays are arranged, and can be constituted inexpensively with avoiding generation of a deflection in a focal direction resulting from thermal expansion of each light-emitting element array unit, streaks on images, etc., and provide an imaging apparatus using the same. SOLUTION: Adjacent light-emitting element array units are coupled directly or via a connecting member with each other, so that the whole is constituted integrally. The integral constitution is fixed to a supporting member 60 for supporting the constitution in its entirety only at one point by a stepped screw 80 not to generate any deviation in an arrangement direction A of light-emitting elements.</p> |
