A recording material processing apparatus includes a processing tray, a detecting unit, a stapling unit, an instructing unit, a control unit, a switching unit, and a notifying unit. The detecting unit detects recording material placed in the processing tray. The stapling unit executes a stapling process for the recording material placed in the processing tray. The instructing unit outputs a stapling process execution instruction. Upon receipt of the execution instruction in a state in which the detecting unit has detected a recording material inserted in the processing tray from an outside of a main body of a main body apparatus, the control unit cause the stapling process to be executed. The switching unit switches a position of the stapling unit among a plurality of positions. The notifying unit provides notification of a placement position of the recording material in the processing tray corresponding to each of the plurality of positions.

A medium conveying apparatus includes a first roller, a second roller located to face the first roller, to hold and convey a medium with the first roller, a drive shaft to rotate the second roller, a motor to rotate the drive shaft, and a joint to connect the second roller and the drive shaft. The joint is configured to keep connecting the second roller and the drive shaft when the second roller moves in a vertical direction. The drive shaft is located at an intermediate position between a first position where the second roller is in contact with the first roller and a second position where the second roller separates most from the first roller in the vertical direction. A distance between the second position and the intermediate position is greater than a radius on cross section of the second roller in the vertical direction.

A medium transporting device includes a driving roller that transports a medium and that is driven to rotate, a driven roller that nips the medium between the driving roller and the driven roller and rotates in accordance with the rotation of the driving roller, a rotary shaft of the driven roller, a first pressing member that presses the rotary shaft in a direction in which the driven roller comes into contact with the driving roller, a second pressing member that presses the rotary shaft in a direction in which the driven roller comes into contact with the driving roller, and a spacer member that is integrally provided with a first spacer interposed between the rotary shaft and the first pressing member and a second spacer interposed between the rotary shaft and the second pressing member.

An image forming apparatus is provided. The image forming apparatus includes a paper-feed unit, a developing unit to form an image in a printing medium, an insertion unit including first and second rollers configured to insert the printing medium conveyed from the paper-feed unit into the developing unit, and a guide unit rotatably disposed about a rotation shaft of the first roller and configured to guide the printing medium moving from the paper-feed unit to the insertion unit and selectively press the first roller to the second roller.

The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.

A recording material processing apparatus includes a processing tray, a detecting unit, a stapling unit, an instructing unit, a control unit, a switching unit, and a notifying unit. The detecting unit detects recording material placed in the processing tray. The stapling unit executes a stapling process for the recording material placed in the processing tray. The instructing unit outputs a stapling process execution instruction. Upon receipt of the execution instruction in a state in which the detecting unit has detected a recording material inserted in the processing tray from an outside of a main body of a main body apparatus, the control unit cause the stapling process to be executed. The switching unit switches a position of the stapling unit among a plurality of positions. The notifying unit provides notification of a placement position of the recording material in the processing tray corresponding to each of the plurality of positions.

A sheet feeding device includes a sheet feeding portion, a side end regulating portion, a feeding portion, first and second feeding roller pairs, an abutment member, an obliquely feeding roller pair, and first and second contact-and-separation mechanisms. Feeding of a long sheet is stopped after the sheet is fed to an upstream side of the second feeding roller pair by the feeding portion, and then is resumed in a state in which the first feeding roller pair is changed from a separated state to a feedable state and in a state in which the obliquely feeding roller pair is put in a separated state, and then the sheet is fed to the second feeding roller pair. A short sheet fed by the first feeding roller pair is obliquely fed by the obliquely feeding roller pair and then is fed to the second feeding roller pair.

A printing device includes a sheet placement plate, an ejection roller module and an ejection control module. The ejection roller module is located near the sheet placement plate to eject at least one paper sheet. The ejection control module is connected with the ejection roller module. The ejection roller module is selectively in a released state or an ejection state under control of the ejection control module. When the ejection roller module is in the released state, the at least one paper sheet is transferred to the sheet placement plate through the ejection roller module. The ejection roller module is in the ejection state, the at least one paper sheet is outputted by the ejection roller module.

A cutting head-including printer includes at least one driving roller, a pair of side pinch rollers, a center pinch roller provided between the pair of side pinch rollers, and a roller moving mechanism that causes the center pinch roller to approach, or to be separated from, the at least one driving roller. The cutting head-including printer sets whether to perform cutting after printing or to perform the printing after the cutting. During the cutting performed after the printing, the cutting head-including printer separates the center pinch roller from the at least one driving roller. During the cutting performed before the printing, the cutting head-including printer locates the center pinch roller at a position where the center pinch roller holds a recording medium together with the at least one driving roller.

There is provided a printing apparatus including: a recorder; first and second conveying rollers; a first member which includes the first conveying roller and in which the first conveying roller is supported shakably; and a second member which includes the second conveying roller. The first member includes: a roller support having: an extending part which extends in an extending direction of a rotation shaft of the first conveying roller, and first and second supports which rotatably supports first and second ends of the rotation shaft of the first conveying roller, respectively; and at least one pressing part configured to press a central area of the extending part in a pressing direction extending from the first conveying roller to the second extending roller, in a state that the first and second conveying rollers are brought into contact with each other.
