<p>An optical print head includes light-emitting array chips (2), driver ICs (4), lens array (10), and circuit board (1) on which the light-emitting array chip (29 and driver IC are mounted. The light-emitting array chips (2) are aligned in line on the circuit board in the direction in which the rod lens extends. Each light-emitting array chip (2) has light emitting elements (43) therein aligned in line. The driver IC (4) electrically is connected to the corresponding light-emitting array chip (2), and electrically drives the light-emitting array chip (2) to emit light. The lens array (10) gathers the light emitted from said light-emitting elements (43) and emanates the gathered light. The lens array (10) has a focal point and is positioned relative to the light-emitting array chip (2) so that the focal point of the lens array (10) is on the light-emitting elements (43). The circuit board has a surface on which the light-emitting array chip (2) and the driver IC (4) are mounted. The circuit board (1, 75) supports the light-emitting array chip (2) so that the light-emitting elements (43) emit the light in a direction parallel to the surface of the circuit board (1, 75). <IMAGE></p> |
