Even if 24 is escaped from the opening 116, the prism may be exposed to the opening, and the prism may be scratched or dusted through the opening, or the prism may be touched with a fingerprint or a scratch. This is prevented and is realized by the operation of attaching and detaching the negative carrier 24.

When the lens system 26 is retracted from the printing optical axis J and the lens system 26 is replaced with another lens system, since the other lens system is large, the negative carrier of the lens system is mounted. When the prism 108 cannot be provided on the side of the unit and the printing light is reflected by the mirror 108 for photometry, the mirror 108 does not interfere with the cover body 152 as shown in FIG.

The cover body 152 is the prism 1
However, the present invention is not limited to this, and a lens system in which a lens is provided on the incident side of the prism and the lens is covered by the cover body is also possible as the lens system. Further, as the lens system in which the side of the opening 116 is covered with the cover body 152, in addition to such a prism-equipped lens, there is no prism, or the lens body facing the opening 116 and the negative carrier 24 is removed when the cover body is removed. It includes various lens systems that would otherwise be exposed. Even if a lens without a prism or a lens provided on the entrance side of the prism is used, even if the negative carrier 24 is made to escape from the opening 116, as in the case of the prism, the lens is exposed through the opening and the lens is damaged through the opening. It prevents the lens from being dusty or from being touched by the hand with fingerprints or scratches.
