Abstract: An optical scanning device includes a polygon scanner that deflects and scans light beams, a body on which the polygon scanner directly mounted, and a heat dissipating unit that dissipates heat of the deflection scanning unit. The heat dissipating unit is located at a position on an outer surface of the body corresponding to the deflection scanning unit. The body is provided with a pair of wall portions on the outer surface. The wall portions face each other with the heat dissipating unit between them, and extend in a direction in which air blown by an air blowing unit flows to form an air-flow path.

Abstract: An optical scanning device configured to irradiate an object with light generating from a light source via at least one mirror with a first end portion and second end portion which are attached to a housing and to scan the object with the irradiating light is provided, wherein the first end portion of the at least one mirror is movably supported by the housing and the second end portion of the at least one mirror is bonded to the housing.

Abstract: A curved surface forming apparatus includes a first member to be curved; a second member which is placed with a distance from the first member and holds the first member; and a pressurizing mechanism which pressurizes the first member and the second member to curve at least a part of the first member toward at least the second member.

Abstract: An ink supply pipe 70 is inserted into a sponge 44 to reach a central or lower portion thereof where ink density higher. Thereby, the ink can be fed stably to a nozzle 42 and to reduce influence of the air introduced through an ink supply tube 60 and an ink supply pipe 70. Lateral holes 72 for ink discharge are provided on a side wall of the ink supply pipe 70. Thereby, a sufficient amount of the ink can be supplied from the lateral holes 72 of the supply holes 70, even when the sponge 44 is crushed upon insertion of the ink supply pipe 70 to narrow the tip orifice of the ink supply pipe 70.
