There is provided a dustproof structure of an optical box in which intrusion of dust into the optical box can be prevented. Laser beams deflected by a polygon mirror of an optical box are transmitted through an optical system and exit from an opening outside the optical box, and reach a photographic printing paper. In this case, when dust and the like adhere to the polygon mirror or the optical box, the function of such an optical element deteriorates. Therefore, a dustproofing effect is required by the optical box. Accordingly, by supplying air into the optical box using a fan to thereby pressurize an interior of the optical box, the intrusion of dust from outside of the optical box into the optical box can be prevented, thereby making it possible to prevent dust or the like from adhering to the polygon mirror or the optical system.

In a photosensitive material exposure apparatus in which a plurality of rows of photosensitive materials can be subjected to scan-exposure, in a case in which there is only one row of a photosensitive material, scanning is not wasted and exposure time is reduced. Images are exposed by a single scan exposure system in which the column direction of a photographic printing paper (P) is a main scanning direction and a direction orthogonal to the column direction is a sub-scanning direction. In case of single row exposure, scan-exposure is effected only on a necessary row. Accordingly, exposure time can be reduced.

A method of forming a wiring board comprises: a step of forming a receptive layer having a porous structure on a substrate; a step of forming wiring portions in a desired conductive pattern on a surface of the receptive layer by ejecting a colloidal metal solution for drawing by an ink-jet system based on image date of the conductive pattern; and a step of performing a migration-proof treatment on at least part of the receptive layer exposed between mutually adjacent wiring portions.

A die for extrusion-forming a honeycomb structure which includes: a die base provided with ceramic puddle introducing holes and slits in communication with the ceramic puddle introducing holes; and a substrate layer, which roughly defines the final width of the slits, and a surface layer, which precisely defines the final width of the slits, formed on the die base in this order so that the final width of the slits becomes 15 to 200 μm, wherein the surface layer is made up of tungsten carbide particles which are 5 μm or less in average particle diameter and contain W3C as a main ingredient. According to this invention, there is provided a die for extrusion-forming a honeycomb structure which can restrain fluctuation in extrusion-forming speed among its parts and resistance to pushing force, both caused at the time of extrusion-forming, to be very small and is superior in productivity and durability.

A lenticular print that allows stereoscopic viewing is formed by forming lenticular lenses, each having a convex sectional shape, on an image-recorded member, which has groups of parallax images arranged and written thereon. Each group of parallax images includes strips of parallax images. The lenticular lenses are formed at positions corresponding to the individual groups of parallax images. The lenticular print is formed through a partition wall forming step of forming partition walls between the groups of parallax images on the image-recorded member, the partition walls extending in a longitudinal direction of the parallax images and having a predetermined height; and a lens forming step of forming the lenticular lenses between the partition walls by depositing a transparent material between the partition walls so that the deposited transparent material bulges upward from the partition walls due to surface tension thereof to have a substantially circular sectional shape.
