Abstract: The optical scanning device scans an object with plural laser beams, and includes a light source, which emits plural parallel laser beams in a predetermined direction and which has a stem portion having a first notch; and a support having an opening, with which the light source is engaged so as to be rotatable on an axis parallel to the plural light beams, and a second notch located on a part of the opening so as to overlap with the first notch when the light source is engaged with the opening. By inserting a slotted screwdriver, etc., into the space formed by the two notches and rotating the screwdriver, the angle of the light source can be adjusted and thereby the pitches of the laser beams can be adjusted.

Abstract: A first laminated body is formed by printing an electroluminescent layer that emits radiant light through the first substrate, as well as a first resistive film, upon a flexible and optically transparent first substrate including a principal surface that functions as an operable surface. A second laminated body is formed by printing a second resistive film upon a second substrate. A second resistive film is printed upon a second substrate. The laminated body and the second substrate are then unified such that the first resistive film and the second resistive film face each other and are spaced apart by a predetermined distance.

Abstract: A plastic lens comprising the first acrylic hard coated layer formed on the outside surface of a plastic lens base and, on the inside surface, an antifogging coated layer while interposing of the second acrylic hard coated layer is obtained by coating both sides of a plastic lens base with an acrylic hard coating agent, masking the outside surface with a peelable masking agent (e.g., a coating composition containing poly(vinyl chloride) or a vinyl chloride-vinyl acetate copolymer), coating at least the inside surface with an antifogging agent, and removing the masking layer. As the hard coating agent or antifogging agent, use can be made of an ultraviolet-curable resin composition, and as the masking agent, a coating composition containing a poly-(vinyl chloride) or vinyl chloride-vinyl acetate copolymer may be employed.
