Abstract: The light source body of an optical scanner includes a main frame and a disc portion. The main frame is formed into a cylindrical columnar shape so as to irradiate the light beams from a front end thereof. The disc portion protrudes radially outward from a rear end side of the main frame. A side plate of the housing have a through-hole. The side plate includes a support member installed on the outer surface. The support member has an arc surface formed to extend along a edge portion of the through-hole. A pressing member is configured to press the disc portion of the light source body against the arc surface of the support member in such a state that the front end of the main frame is inserted into the through-hole and that an end surface of the disc portion makes contact with the side plate of the housing.

Abstract: An exposure device includes a polygon motor, an fθ lens, and a heat-insulating room. The polygon motor is driven into rotation while producing heat, which makes it likely that the temperature of a portion of the fθ lens near a housing right wall becomes lower than that of a portion of the fθ lens near a housing left wall. The exposure device further includes a recess located above the fθ lens and extended in a right-and-left direction. The heat-insulating room is formed by disposing a plate above the portion of the fθ lens near the housing right wall to cover the recess. Thus, the plate restricts upward heat release from the portion of the fθ lens near the housing right wall.

Abstract translation: 曝光装置包括多边形电机，透镜和绝热室。 多边形电动机在产生热的同时被驱动旋转，这使得靠近壳体右壁的部分透镜透镜的温度可能比靠近壳体左壁的部分透镜透镜的温度低。 曝光装置还包括位于顶部透镜上方并沿左右方向延伸的凹部。 绝热室通过在靠近壳体右壁的顶部透镜的部分上方布置以覆盖凹部而形成。 因此，板限制了从壳体右壁附近的fta透镜的部分向上的热释放。

Abstract: A head unit includes a mount (first mount). An inkjet head includes a nozzle for ejecting ink. The mount includes a Z-direction biasing member and a Z-direction positioning member. The Z-direction positioning member positions the inkjet head in an ink ejecting direction (Z (+) direction, lower direction) of the nozzle by holding a sphere to be rotatable, and bringing the sphere into contact with the inkjet head. The Z-direction biasing member biases the inkjet head against the Z-direction positioning member.

Abstract: A head unit includes a recording head, a pipe member, and an ink supply section. The recording head ejects an ink. The pipe member supplies the ink to the recording head. The ink supply section supplies the ink to the pipe member. The ink supply section includes a flow channel in which the ink flows to one end of the pipe member. A ceiling surface constituting a part of the flow channel inclines such that a height of the ceiling surface from a bottom surface constituting a part of the flow channel increases toward the one end of the pipe member.

Abstract: An ink discharge device includes a recording head and a damper. The recording head has a nozzle which discharges an ink. The damper reduces pressure variation of an ink in the recording head. The damper includes a damper body, a film and a restricting member. The damper body has a damper chamber. The film is deformed according to the pressure variation of an ink in the damper chamber and makes a volume of the damper chamber change. The restricting member faces to the film and restricts deforming of the film in a direction in which the volume of the damper chamber is increased.
