Abstract: A sheet width aligning device includes an elevator tray, a pair of guides, and a pinion. The pinion is rotatably supported by inserting a shaft portion into a shaft hole formed in the pinion. The shaft portion projects from the elevator tray. The sheet width aligning device is configured to move the pair of guides so as to increase or decrease the distance between the guides in operative association with the pair of racks meshed with the pinion. The sheet width aligning device includes a pressing mechanism. The pressing mechanism is provided on the back face side of the elevator tray and includes an abutment member that abuts against the pinion. The pressing mechanism separates the abutment member away from the pinion at the lower position, while abutting the abutment member against the pinion to press the pinion at the upper position.

Abstract: 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.
