Each of four outer side surfaces of each of a plurality of square pipes include a groove portion formed along a longitudinal direction of each of the plurality of square pipes and a pair of ridge line portions forming edge portions on both sides of the groove portion. An additional member includes a contact plane which is a plane in contact with a portion of the plurality of square pipes. The additional member is fixed to a plurality of first target pipes which are some of the plurality of square pipes with the contact plane in contact with at least one of the pair of ridge line portions, or the additional member is fixed to a second target pipe which is one of the plurality of square pipes with the contact plane in contact with the pair of ridge line portions.

Structure and image forming apparatus

A structure includes a plurality of joined square pipes. Four corner portions of each of the plurality of square pipes include three first corner portions and one second corner portion. The three first corner portions are formed by bending a single metal plate. The one second corner portion includes two edge portions of the metal plate and a welded portion where the two edge portions are joined.

An optical scanning device has a rotary multiple-face mirror, a lens, a housing, and a cover member. The housing has a housing space in which the rotary multiple-face mirror and the lens are housed. The cover member covers the housing space in the housing. The housing has a light emission opening through which a light beam is emitted, and outside the light emission opening in the housing, a light transmitting member which transmits the light beam is provided to close the light emission opening. The cover member has a body part which covers the housing space and a fastening part which fastens the light transmitting member by pressing it toward the light emission opening.

Optical scanning device and image forming apparatus therewith

An optical scanning device includes a housing and a cover. An engaging hole is formed in the housing and an engaging piece is formed in the cover. The engaging piece has a first portion following a side wall portion of the housing and a second portion folded so as to face the first portion at an interval. When the engaging piece has been inserted into the engaging hole, the first portion is elastically deformed toward the side wall portion of the housing, and the second portion is elastically deformed toward the first portion and abuts a lower portion of an inner edge of the engaging hole, so that the engaging piece and the engaging hole are engaged with each other and the cover is pressed with respect to the housing by the restoring force of the engaging piece.

A sheet feeder includes a casing, a sheet stacking portion, a sheet conveyance path, a feed roller, a separation pad, a holder, a mounting portion and a guiding member. The sheets are placed on the sheet stacking portion and fed in a predetermined direction in the sheet conveyance path. A nip portion, through which the sheet passes, is formed between the feed roller and the separation pad. The holder fixedly supports the separation pad and is mountable into and removable from the mounting portion of the casing. The guiding member guides the holder. The posture of the holder is changeable between a first posture in which a predetermined clearance is formable between the guiding member and the holder when the holder is mounted into the mounting portion and a second posture in which the holder is pressed against the guiding member when the sheet passes through the nip portion.

Sheet feeder and image forming apparatus provided with same

An optical scanner includes a housing and a cover member attached to the housing. A tubular pin attachment portion is installed in a side portion of the housing. A tapping screw pin is inserted into the pin attachment portion when the housing is fastened and fixed to a fastening target with the tapping screw pin. A pin head accommodating portion formed into a tubular shape to extend in a coaxial relationship with the pin attachment portion is installed in a side portion of the cover member. The pin head accommodating portion is configured to accommodate a head portion of the tapping screw pin inserted into the pin attachment portion.
