A layboy includes an upper belt section with a plurality of transversely spaced upper belts that extend in a longitudinal direction such that bottom portions of the upper belts lie in a first plane that defines an upper boundary of a transport path through the layboy and a lower belt section having a plurality of transversely spaced lower belts that extend in the longitudinal direction such that top portions of the lower belts lie in a second plane that defines an upper boundary of the transport path. The bottom portion of one of the top belts and/or the top portion of one of the bottom belts extends away from the transport path to define a gap in the transport path at which scrap moving through the layboy can fall out of the transport path.

An optical connector cleaning tool includes a cleaning tool main body, a feed-side bobbin, a cleaning head (cleaning portion), a winding-side bobbin, a moving body that moves at the time of cleaning, a feed mechanism that sends an unused cleaning medium in synchronism with the moving body, and a winding mechanism that drives the winding-side bobbin. The feed mechanism moves a turn-back portion at one point where the cleaning medium is turned back in a direction to separate from the winding-side bobbin. The winding mechanism includes a driving piece that engages with a rotation body of the winding-side bobbin. The driving piece slips with respect to the rotation body when a load to press engaging projections of the rotation body has reached a predetermined load.

A cleaning device cleans a conveyance face of a conveyance member conveying a sheet. The cleaning device includes a delivery roller, a pressure roller, a fixed roller and a winding roller. The delivery roller supports a web roll that a belt shaped web is wound into a roll. The pressure roller brings the web delivered from the web roll into pressure-contact with the conveyance face. The fixed roller keeps an extending angle of the web passed from between the conveyance member and the pressure roller constant. The winding roller winds the used web passed the fixed roller into a roll.

A used paper supply device includes a first paper feed unit and a second paper feed unit for feeding used paper and cleaning unit for cleaning a surface of a roller of the paper feed units, in which when the used paper is fed from the first paper feed unit, the surface of the roller of the second paper feed unit is cleaned.

A belt feeding device includes an endless belt, stretching rollers including a tension roller, a bearing member supporting the tension roller, a beating support member supporting the bearing member, an urging member urging the tension roller, a supporting member supporting the bearing supporting member, and a locking member. The locking member is movable between a first position where an engagement between the locking member and one of the bearing support member and the bearing member is released and the bearing member is permitted to move so as to apply the tension to the belt, and a second position where the locking member locks the bearing member by engaging with the bearing support member and the bearing member and the bearing member is restricted to move. The bearing member, the bearing support member, the urging member, and the locking member constitute a unit to be integrally dismountable from the supporting in the second position.

A sheet processing apparatus includes a conveyance unit configured to convey a sheet in a sheet conveyance direction, a punching unit configured to punch a hole to the sheet being conveyed by the conveyance unit, a moving unit configured to move the punching unit in an intersecting direction intersecting the sheet conveyance direction, a detection unit arranged upstream of the punching unit in the sheet conveyance direction and configured to change an output value based on a position of an edge portion, in the intersecting direction, of the sheet being conveyed, a cleaning portion configured to clean the detection unit, and an interlocking portion configured to move the cleaning portion so as to clean the detection unit by interlocking with a movement of the punching unit in the intersecting direction.

A transport device includes a transport belt having a support surface configured to support a medium, a cleaning roller including an absorbent member configured to absorb cleaning liquid, and configured to clean the support surface as the absorbent member comes into contact with the support surface, a supply unit configured to supply the cleaning liquid to the cleaning roller, and a squeeze member to squeeze the absorbent member as the cleaning roller rotates in a state in which the squeeze member is in contact with the absorbent member. The supply unit is configured to be switched between a supply state in which the cleaning liquid is supplied to the cleaning roller and a non-supply state in which the cleaning liquid is not supplied to the cleaning roller, and the squeeze member squeezes the absorbent member while the supply unit is in the non-supply state.

A sticky-layer-cleaner for removing residues adhered to a sticky flat layer includes a receptacle for a cleaning-liquid and a cleaning-roll in contact with the sticky flat layer, wherein the cleaning-roll includes an elongated carpet fabric which is helically folded around the cleaning-roll and a pile of which includes yarn tufts in loop and/or cut configuration, and the cleaning-roll further includes a helical channel along the length of the folded carpet fabric for draining the cleaning-liquid from the cleaning-roll and/or for wetting the cleaning-roll with the cleaning-liquid.

An image forming apparatus includes a drawer unit, a sheet inverting unit, a sheet guide plate, and a projection. The drawer unit is drawable from an apparatus body. The sheet inverting unit is disposed in the apparatus body, and pulls a sheet into a lower portion of the drawer unit to invert the sheet. The sheet guide plate is disposed on the sheet inverting unit to face the drawer unit, and includes a recess extending in a pull-out direction of the drawer unit that crosses a direction in which the sheet is transported. The projection protrudes toward the recess from a portion of a lower surface of the drawer unit facing the sheet guide plate near a pull-out start point in the pull-out direction and on a rear of a transport area of the sheet.

A belt feeding device includes an endless belt, stretching rollers including a tension roller, a bearing member supporting the tension roller, a beating support member supporting the bearing member, an urging member urging the tension roller, a supporting member supporting the bearing supporting member, and a locking member.

The locking member is movable between a first position where an engagement between the locking member and one of the bearing support member and the bearing member is released and the bearing member is permitted to move so as to apply the tension to the belt, and a second position where the locking member locks the bearing member by engaging with the bearing support member and the bearing member and the bearing member is restricted to move. The bearing member, the bearing support member, the urging member, and the locking member constitute a unit to be integrally dismountable from the supporting in the second position.
