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).
摘要翻译：一种能够防止过滤器保持器（8）和发光管（2）之间的捕获的光学打印头（1），以防止灰尘的产生并且在不将过滤器暴露于周围环境的情况下更换发光管（2）。过滤器保持器（8）与光源（2）和自发透镜阵列（14）分开设置，以防止由于过滤器保持器（8）与灯的接触而产生来自过滤器保持器（8）的灰尘源（2）和自透镜阵列（14）。基座（9）被布置成仅接收过滤器保持器（8）暴露于环境大气中，导致灰尘不被粘附到过滤器上。一对光通道（12,13）形成在光路上并且用透光盖（15）封闭，以密封地关闭基部（9），从而防止灰尘在更换期间灰尘进入基座（9）光源（2）。

摘要翻译：一种光学打印机头（1），其能够防止过滤器支架（8）与发光管（2）之间的卡住，从而防止产生灰尘并且实现发光管（2）的更换而不将过滤器暴露于环境大气。过滤器支架（8）与光源（2）和自聚焦透镜阵列（14）分开设置，以防止由于过滤器支架（8）与灯的接触而从过滤器支架（8）产生灰尘源（2）和自聚焦透镜阵列（14）。基座（9）布置成仅接收过滤器保持器（8）暴露于环境大气，从而防止灰尘粘附到过滤器。在光路上形成一对光通道（12,13）并用透光盖（15）封闭以密封地封闭基座（9），由此防止灰尘在更换期间侵入基座（9）光源（2）。
