Printer head device and printer image processing system having the same

Abstract

A head for a printer and an image processing system is provided in which light emitted from light emitting elements formed on a substrate of the head does not leak from pinholes of a non-corresponding light emitting elements and does not interfere with light emitted by other light emitting elements, so that satisfactory printing can be carried out. An aperture has on opposite ends sandwiching portions and covers a substrate to sandwich a carriage. Concave portions are formed correspondence with light emitting elements. Pinholes are provided in a front wall and an insulating black coat is formed on the surfaces of the concave portions to prevent a short circuit. Light from the light emitting elements which does not pass through the pinholes is absorbed by the surfaces of the concave portions.
