A sheet feeder includes: a multi-purpose tray; a guide roller provided at an end of the multi-purpose tray to come into contact a recording paper sheet protruding from the end of the multi-purpose tray; a spring member that supports the guide roller elastically and movably in upward and downward directions; and a pick-up roller that is disposed apart from the end of the multi-purpose tray movably in the upward and downward directions and, when moved downward, pulls out the recording paper sheet protruding across an upper side of a peripheral surface of the guide roller from the end of the multi-purpose tray while being pressed against a leading end portion of the recording paper sheet.

An image forming apparatus includes a housing, a feeding tray inserted into and pulled out from the housing, an image forming unit, and first and second guide members. The feeding tray includes a first accommodation part in which a roll body having a configuration where a sheet-shaped medium is rolled in a roll shape is accommodated and a second accommodation part in which stacked sheet-shaped media are accommodated. The first guide member guides a sheet-shaped medium to a conveying path. The second guide member guides a roll medium unrolled from the roll body to the conveying path. The second guide member is movable between a guide position for guiding the roll medium to the conveying path, and a retreat position further distant from the first guide member than the guide position and where the second guide member does not interfere with a sheet-shaped medium accommodated in the second accommodation part.

A sheet conveyance apparatus includes a stacking portion, a feeding portion, first and second detection units, a controller, and a setting unit. The feeding portion separates and feeds sheets stacked on the stacking portion. Of a sheet fed by the feeding portion, the first detection unit detects skewing, and the second detection unit detects flip-up. The controller stops feeding where skewing of the sheet is detected by the first detection unit and where flip-up of the sheet is detected by the second detection unit. The setting unit sets a different-width mixed document mode in which a plurality of sheets having different widths is stacked on the stacking portion. In a case where the different-width mixed document mode is set by the setting unit, the controller does not stop feeding based on skewing detected by the first detection unit but stops feeding based on flip-up detected by the second detection unit.

A conveying apparatus includes: a casing formed with a first sheet-conveyance passage and a second sheet-conveyance passage positioned inwardly as compared with the first sheet-conveyance passage; a cover member including a first resin member having a first guide surface for defining the first sheet-conveyance passage, a second resin member attached to the first resin member and located on an inner side of the casing than the first guide surface and defining the first sheet-conveyance passage, and a third resin member attached to the second resin member at a position opposite to the first resin member with respect to the second resin member and having a third guide surface for defining the second sheet-conveyance passage; and a metal frame attached to the second resin member at a position between the second resin member and the third resin member.

A sheet tray, including a tray body having a bottom plate, and a sheet guide, is provided. The sheet guide includes a guide plate to align sheets at a predetermined position, a lever, a swingable device having a boss and a guide groove, and a stopper pivotably connected with a hinge. The boss guided in the guide groove moves the lever between a first position, wherein the boss is in a first section in the guide groove and the stopper is lowered to an engaged position, with an engageable part being engaged with the bottom plate; and a second position, wherein the boss is in a second section in the guide groove and the stopper is uplifted to a separated position with the engageable part being separated from the bottom plate. When the lever moves from the first position to the second position, the lever tilts by ascending and pivoting.

A conveying apparatus includes: a casing formed with a first sheet-conveyance passage and a second sheet-conveyance passage positioned inwardly as compared with the first sheet-conveyance passage; a cover member including a first resin member having a first guide surface for defining the first sheet-conveyance passage, a second resin member attached to the first resin member and located on an inner side of the casing than the first guide surface and defining the first sheet-conveyance passage, and a third resin member attached to the second resin member at a position opposite to the first resin member with respect to the second resin member and having a third guide surface for defining the second sheet-conveyance passage; and a metal frame attached to the second resin member at a position between the second resin member and the third resin member.

A sheet feeding apparatus includes a supporting portion and a feeding unit. The supporting portion supports a sheet and is capable of being drawn out from and being attached to an apparatus body. The feeding unit is provided in the apparatus body and includes a feeding portion, a conveyance portion, a separation unit, and a guide member. The feeding portion feeds the sheet supported by the supporting portion. The conveyance portion conveys the sheet. The separation unit forms a separation nip with the conveyance portion and is detachable from the feeding unit. The guide member includes a guide surface and a lower surface. The guide surface guides the sheet to the separation nip. The lower surface is provided below the guide surface and includes an exposing portion exposing at least a part of the separation unit.

An image forming apparatus includes an apparatus main body, an output tray, and a holding member. The output tray is rotatable about a first rotation shaft between a closed position and an open position. The holding member is rotatable about a second rotation shaft. The output tray comes into contact with the holding member halfway through rotation of the output tray from the closed to the open position. When the output tray is rotated to the open position, the holding member rotates to a retracted position while being in contact with the output tray. When viewed in a direction crossing a recording-material discharge direction, the first rotation shaft is located downstream from the second rotation shaft in the discharge direction, and a center of gravity of the holding member is located downstream from the second rotation shaft in the discharge direction when the holding member is at the retracted position.

A printing cassette includes: a case including a first case portion, a second case portion, and a third case portion; a first tape, at least a portion of which is accommodated in the third case portion; and a gear, a portion of which is accommodated in the second case portion and the other portion of which is located outside of the case, the gear being rotatable about a rotation axis parallel to a first direction. The first case portion has an outlet through which the first tape is discharged. The first case portion, the second case portion, and the third case portion are disposed in an order of the first case portion, the second case portion, and the third case portion in the first direction.

A spring is located between a separation pad and a frame. The frame is configured to receive a downward reaction force that is a reaction force of an urging force of a spring. A rotation shaft and a contact piece are located at one side of the separation pad in a width direction. The frame has an upper edge in a first region defined between one end and another end of the rotation shaft in the width direction. A height of the upper edge in the first region is at a same height or below a rotation axis. The frame includes a standing wall in a second region in the width direction. The standing wall extends farther upward than the upper edge in the first region. The second region includes a region in which the separation pad is located. The second region is other than the first region.
