摘要： An optical printer head (1) capable of preventing catching between a filter holder (8) and a luminous tube (2) to prevent production of dust and attaining replacement of the luminous tube (2) without exposing filters to an ambient atmosphere. A filter holder (8) is arranged separately from the light source (2) and a selfoc lens array (14), to prevent production of dust from the filter holder (8) due to contact of the filter holder (8) with the light source (2) and the selfoc lens array (14). A base (9) is arranged so as to receive only the filter holder (8) from being exposed to an ambient atmosphere, resulting in dust being kept from adhering to the filters. A pair of light passages (12,13) are formed on a light path and closed with a light-permeable cover (15) to sealedly close the base (9), thereby preventing dust from intruding into the base (9) during replacement of the light source (2).

摘要： An optical printer head capable of minimizing production of a ghost by incidence of light reflected on a filter holding hole. Light emitted from a light source is reflected out of a maximum allowable incident angle to minimize generation of a ghost due to incidence of reflected light on a selfoc lens array while reducing a size of a filter holding hole for holding each of filters therein. Also, a peripheral surface of the filter holding hole may be rendered rough, to thereby provide a scattering surface, resulting in preventing repeated reflection of light emitted from the light source on the peripheral surface of the filter holding hole.
