A sheet stacking device includes: a sheet discharge unit; a sheet stacking unit; a pair of cursors; and a control unit. The cursors perform widthwise alignment processing in which the cursors contact lateral end surfaces of the sheet to perform widthwise alignment. The control unit, before a leading end of the sheet reaches a sheet stacking surface, executes sheet guiding processing in which the cursors are positioned at a sheet guiding position to contact a bottom surface of the sheet and guide the sheet toward the sheet discharge direction. The control unit, when the leading end of the sheet passes a predetermined position, positions the cursors at a retracted position that is further outward than the lateral end surfaces of the sheet are, and once a trailing end of the sheet passes through the sheet discharge unit and the sheet is placed on the tray, executes the widthwise alignment processing.

A fixing device includes a heating body, a pressuring body, a lateral plate supporting the heating or pressuring body, a first supporting body supporting the heating or pressuring body, a second supporting body including a roller, a tensile spring between the first and second supporting bodies, an eccentric cam, a rotating shaft, a protrusion, a driving part, and a pressing member. The cam is supported between the first and second supporting bodies swingable in the lateral plate and has a depression gradually inclined from an upstream side to a downstream side in a rotation direction. The protrusion is protruded from the rotating shaft and meets the depression. The pressing member presses the cam opposite the protrusion. The cam rotates and meets the roller to shift the second supporting body and to extend and contract the spring, and changes a nip pressure from a first pressure to a lower second pressure.

In an image forming apparatus, a reservation managing unit receives a reservation request from a mobile terminal device of a user, and registers reservation information. The reservation information indicates (a) a usage time zone specified by the received reservation request and (b) the mobile terminal device. The operation restriction unit changes an operation control mode from an operation permission mode to an operation prohibition mode if (a) the mobile terminal device detected by a terminal detecting unit is a mobile terminal device of a reserving user who reserved as the usage time zone a current or a next time zone and (b) there are no currently using users. The operation permission mode is a status where an operation of an unspecified user can be received, and the operation prohibition mode is a status where a user operation is prohibited until a release operation of the reserving user.

Image forming apparatus

An image processing apparatus includes a document table, an image reading portion, a cover portion, a presser sheet, and a sheet winding portion. The presser sheet is provided on the cover portion, and contacts the document on the document table when the cover portion is positioned at the closing position. The sheet winding portion allows a first portion of the presser sheet to extend along the document table while holding a second portion of the presser sheet in a wound state. The sheet winding portion can feed the second portion when an external force is applied to the first portion. In the cover portion, a retreat space is formed so that the first portion of the presser sheet and a portion of the second portion fed from the sheet winding portion can retreat into the retreat space.

Image processing apparatus

A sheet post-processing apparatus includes a processing tray, a shift member, a discharge tray, a discharge roller pair, and a pressing member. The shift member moves a sheet loaded on the processing tray in a sheet width direction. The discharge roller pair discharges a sheet on the processing tray onto the discharge tray. The pressing member presses down a sheet discharged onto the discharge tray. The pressing member has an arm portion which rotates in the sheet conveyance direction about a rotation fulcrum, and a roller which is attached to the arm portion to be rotatable in the sheet width direction, and the pressing member is selectively disposed in a first position where the roller presses down the upstream-side end part of a sheet discharged onto the discharge tray, or in a second position where the roller contacts a lower surface of a sheet on the processing tray.

A sheet feeder includes a tray configured to load a sheet to be fed thereon. The tray has a tray upper face and a pair of cursors. The tray upper face has a recessed portion, a guide plate and a feeding route. The recessed portion extends along the width direction on an upstream side from the pair of cursors in the feeding direction. The guide plate is configured to cover an upper side of the recessed portion. The feeding route is formed between the recessed portion and the guide plate and extending from an inlet port positioned on an upstream side to an outlet port positioned on a downstream side along the feeding direction. The sheet in a state of being passed through the feeding route is aligned with the pair of cursors on the tray upper face and then fed.

A jam detection section detects a sheet jam on a conveyance path based on results of detection by a sheet detection sensor. A printing stop section stops an image formation operation upon the sheet jam detection by the sheet jam detection section. Upon detection of completion of an operation of resolving the sheet jam by a user by a resolving operation detection section, a sheet breakage confirmation section judges, for the sheet taken out from the conveyance path by the user in the operation of resolving the sheet jam and then loaded on a document stand, whether or not there is any sheet lacking portion, based on image data generated by an image reading section. The stopping release section, upon judgment by the sheet breakage confirmation section that there is no sheet lacking portion, permits execution of image formation.

A sheet feeding device includes a lifting plate, a pickup roller, a lifting and lowering mechanism of the lifting plate and an end cursor. The end cursor has a cursor main body and a turning cursor plate. The turning cursor plate is coupled to the cursor main body turnably around a turning shaft extending in a width direction orthogonal to the conveying direction and slidably along a lifting and lowering direction of the lifting plate. The turning cursor plate is configured to be turned toward the downstream side in the conveying direction around the turning shaft by being pushed up with the lifting of the lifting plate while the turning shaft is moved upward so that the sheet is shifted toward the downstream side along an upper surface of the lifting plate with respect to the lifting plate.

The leg member is extendable/contractable in upward and downward directions. The fixed supporting member is extended from a lower end of the leg member in a horizontal direction. The movable supporting member is stored in the fixed supporting member at the lower end of the leg member and extended in another horizontal direction being different from the extending direction of the fixed supporting member.

The fixing device includes: a heating source adapted for performing fixing of a toner image onto a recording medium by heat; a fixing roller including a thin-wall cylinder rotatable about an axis thereof and carrying the heating source therein, the recording medium being placed on a peripheral surface of the cylinder; an annular heat-insulating member coaxially mounted on an outside surface of the fixing roller; and a C-shaped stopper attached to the peripheral surface of the fixing roller for preventing the annular heat-insulating member from moving out of the fixing roller, the C-shaped stopper including at least three engaging portions.

A sheet-handling device comprising an intermediate conveyer passage, an intermediate tray, introduction rollers, conveying rollers and a controller. The controller rotates the introduction rollers and the conveying rollers forward and reverse so as to convey two pieces of sheets successively introduced into the intermediate conveyer passage until their trailing ends separate away from the introduction rollers. The conveying rollers are halted in a state where the leading ends are nipped. After the leading ends of the two pieces of sheets have been nipped in an overlapped manner by the conveying rollers, the conveying rollers are rotated forward to convey the two pieces of overlapped sheets into the intermediate tray.
