摘要： An image forming apparatus such as an electrophotographic copying machine includes an optical system for housing a scanning exposure optical system. The optical system housing is composed of surrounding walls having ends joined in pairs in interdigitating relationship, one of the ends in each of the pairs having an end surface held in abutment against an inner surface of the surrounding wall having the other end. An image forming mechanism is housed in an image forming mechanism housing having a pair of confronting side walls spaced from each other. One of the side walls is taller than the other side wall, and has support fingers projecting laterally from an inner surface thereof. The optical system housing is supported on the support fingers and the other side wall.

摘要： An image forming apparatus such as an electrophotographic copying machine includes an optical system for housing a scanning exposure optical system. The optical system housing has air inlet and outlet holes for introducing air into and discharging air from the optical system housing. The air outlet holes have an opening area greater than an opening area of the air inlet holes. Electrostatic filters are mounted on the optical system housing in covering relation to the air inlet and outlet holes. Thus, the optical system housing is substantially closed. The optical system housing is composed of surrounding walls having ends joined in pairs in interdigitating relationship, one of the ends in each of the pairs having an end surface held in abutment against an inner surface of the surrounding wall having the other end. An image forming mechanism is housed in an image forming mechanism housing having a pair of confronting side walls spaced from each other. One of the side walls is taller than the other side wall, and has support fingers projecting laterally from an inner surface. The optical system housing is supported on the support fingers and the other side wall.

摘要： A pickup roller is movable in a vertical direction and pulls out papers to the paper feed rollers, is provided. The pickup roller moves down towards the papers stacked on the paper tray. A front edge alignment member that aligns the front edge of the papers and a stopper that controls rotation of the front edge alignment member engages the front edge alignment member. A stopper release member pivots the stopper to release it from the front edge alignment member in synchronization to the up and down movement of the pickup roller.
