<p>PROBLEM TO BE SOLVED: To provide a small optical printer head having simple structure and exhibiting excellent productivity. SOLUTION: A first circuit board 1 were an array chip 3 of a large number of light emitting elements 4 and a plurality of circuit conductors 2 are fixed to the upper surface of a supporting plate 9 is mounted on a second circuit board 5 where a driver IC 7 for controlling emission of the light emitting elements 4 and a plurality of circuit conductors 6 are fixed to the side surface of the supporting plate 9. One end of the circuit conductor 6 is led out to the upper end face of the second circuit board 5 are bonded to the circuit conductor 2 of the first circuit board 1 through a thin metal wire 8 thus constituting an optical printer head.</p> |
