Abstract: In a laser printer apparatus, a top cover is arranged to cover a base member, a fixing unit, and a laser scanning unit. At a raised portion formed for reinforcement at an end portion of the base member on the side of fixing unit, a plurality of openings are formed along one direction, with the area of the openings made gradually larger as the distance from a fan increases. On the top cover, a wall portion is formed integrally, protruding to the side of the base member, and by the wall portion and the raised portion, an air passage is formed. Thus, a laser printer is provided in which the fixing unit and the laser scanning unit can be cooled, without necessitating any additional member.

Abstract: A laser beam printer apparatus includes a frame body including side plates formed to support a toner cartridge from a lateral direction and a horizontal plate, a motor secured on the inside of the side plate and having at least a portion arranged above the horizontal plate, and a motor cover arranged below the motor. The horizontal plate has an opening under the motor. The motor cover has locking nails formed to be locked to an edge of the opening.

Abstract: A motor feeding a sheet of paper is arranged inside a frame, and below the motor, a motor cover having a detecting portion for detecting presence/absence of a cartridge is attached on a base member. A signal caught by the detecting portion is transmitted through a wire to a substrate portion arranged outside the frame. The base member has a first cut-and-raised portion formed for engaging with the motor cover, and a second cut-and-raised portion formed at a prescribed position. The wire is connected, through a gap formed by the first cut-and-raised portion between the motor cover and the base member and through the second cut-and-raised portion, to the substrate portion. Thus, a laser printer apparatus can be provided in which the wire connecting the detecting portion detecting presence/absence of a cartridge to the substrate portion can be routed to avoid any influence of heat, at a low cost.

Abstract: An electromagnetic valve mounting portion is formed by upwardly cutting a bottom surface of a frame and bending the upwardly cut portion like a L-shape in such a manner as to have a top surface part extending in substantially parallel with the bottom surface thereof. The electromagnetic valve mounting portion includes a top stationary part, whose top surface part has a U-shaped cutout part, and a pair of bottom supporting parts formed by upwardly bending both side portions of a bottom opening part, which is formed in the upwardly cut portion.
