Abstract
In an optical printer head or image reading apparatus, light emitting diodes, photo detectors and other picture elements are formed, by a specified number of pieces individually, as picture element arrays, and these arrays are linearly arranged. The distance of the picture elements at the adjacent outermost positions of the arrays, that is, the distance between the arrays, and the position of the heightwise direction of the arrays must be composed to be identical. Accordingly, the positioning marks are formed in the arrays in the same manufacturing process of the picture elements, and the distance between the arrays is adjusted at high precision. The arrays are affixed to the wiring substrate with an adhesive, and at this time by adjusting the layer thickness of the adhesive, the positions in the heightwise direction of the array surface are identically controlled. This job is done by adjusting the relative positions of the arrays to be mounted and the wiring substrate, while monitoring the wiring substrate on which the arrays are mounted, by a television camera or the like from the array side surface.
