Abstract:
A bookbinding device includes a punch unit to punch a line of ring holes, an aligning unit disposed downstream from the punch unit in the sheet transport direction, including a pair of first aligning members to align a first sheet, each including a sheet loading surface and a side wall perpendicular to the sheet loading surface, and a pair of rotatable second aligning members, each including a lower surface facing the sheet loading surface of the first aligning member and a contact surface perpendicular to the lower surface to align a second sheet smaller than the first sheet, a swing shaft extending perpendicular to the sheet transport direction, rotatably supporting the second aligning members, a driving source to rotate the second aligning members away from and toward the sheet loading surfaces of the first aligning members, and a ring-binding unit.
Abstract:
A bookbinding system includes an image forming apparatus, a plurality of post-processing apparatuses, a controller, and an operation-and-display unit. The image forming apparatus forms images on recording media and outputs the recording media. The plurality of post-processing apparatuses is connected to the image forming apparatus and includes at least a folding apparatus and a ring-binding apparatus. The folding apparatus folds the recording media according to a plurality of folding types including at least Z-shape folding and double folding. The ring-binding apparatus binds the recording media with a ring. The controller is communicatively connected to the image forming apparatus and the plurality of post-processing apparatuses and prevents simultaneous selection of ring binding and a folding type incompatible with ring binding. The operation-and-display unit displays an indication that ring binding and the folding type incompatible with ring binding are not simultaneously selectable.
Abstract:
An image forming apparatus may include an image forming mechanism configured to form an image and transfer the image on a sheet member, and/or a sheet processing unit. The sheet processing unit may include a sheet aligning unit, an ejection sheet tray configured to stack the sheet member, a sheet stopper configured to align the sheet member at a trailing edge thereof, a return mechanism configured to return the sheet member stacked on the ejection sheet tray to the sheet stopper, and/or a discharging mechanism configured to discharge the sheet member, aligned by the return mechanism, from the sheet stopper to the ejection sheet tray. The sheet aligning unit may include a stacking mechanism configured to stack the sheet member transferred into the sheet aligning unit and/or a sheet aligning mechanism configured to align the sheet member.
Abstract:
A sheet processing apparatus for an image forming apparatus is configured so as to be capable of preventing the misalignment of the end edge of sheets to be scooped and transported from an intermediate tray, and reliably preventing the so-called displacement of end edges in the post-processing steps of sheets as a recording medium with an image formed thereon, and thereby preventing the inferior appearance during binding. A sheet folding apparatus enables a user to easily adjust the misalignment of the fold line of sheets that occurs during actual use, in the middle folding processing steps of sheets as a recording medium with an image formed thereon.
Abstract:
An image forming system includes: an image forming mechanism configured to form an image on a sheet of a transfer material; a post-processor configured to perform post-processing on a plurality of sheets of transfer materials, respectively, there being on at least one of which a respective image has been formed by the image forming mechanism; a transporter to transport the sheets through the post-processor along one or more transport paths; and a controller operable to do the following including, determine a first stopping condition of whether the number of sheets exceeds a reference number, and detect a second stopping condition of whether a cumulative thickness of the sheets loaded in the post-processor exceeds a reference thickness, and stop further image formation by the image forming mechanism when at least one of the first and second stopping conditions is satisfied.
Abstract:
An optical fiber apparatus and manufacturing method thereof includes: forming a bare optical fiber by melting and deforming an optical fiber preform; cooling the bare optical fiber after the bare optical fiber forming step by passing it through a flow channel of a cooling unit through which cooling gas flows; and forming a protective coating layer by supplying a molten resin to a periphery of the bare optical fiber after the cooling step thereby forming an optical fiber. The cooling gas flowing toward a vertically lower end of the flow channel is blocked by the molten resin used to form the protective coating layer, and carbon dioxide gas is supplied toward the flow channel from a position which is vertically below the supply position of the cooling gas and vertically above the blocking position of the molten resin.
Abstract:
The present invention provides a sheet processing apparatus, such as a finisher or sorter, for implementing predetermined processing such as alignment and stapling on an inserted sheet material (i.e. any sheet-form recording medium such as recording paper, transfer paper, or an OHP sheet), and an image forming apparatus comprising the sheet processing apparatus. The sheet processing apparatus comprises a rear end fence horizontal portion that contacts the end portion of the sheet member on the upstream side of a sheet member conveyance direction during alignment of the sheet member, a rear end fence vertical portion for supporting the other parts of the sheet member, and a staple unit for stapling the sheet member. The stapling direction in which a staple is punched by a stapler of the staple unit is set to be parallel to the rear end fence horizontal portion that contacts the rear end portion of the sheet member.
Abstract:
A paper perforating apparatus which can securely prevent a paper end portion from being caught in a punch hole, without having an assist member, such as mylar, in a paper finisher which comprises a perforating device capable of moving in a direction perpendicular to the paper conveyance direction, the paper perforating apparatus, comprising: a paper conveyance device for conveying a paper; a perforating device for perforating the paper; a paper end portion detecting device for detecting an end portion parallel to the conveyance direction of the paper; and a device for moving the perforating device in a direction perpendicular to the conveyance direction, wherein the paper perforating apparatus offsets a standby position of the perforating device, which is in the direction perpendicular to the paper conveyance direction, from a position in which holes are punched out on the paper by a predetermined distance, and the perforating device starts operation of perforation preparation from the standby position after being passed by a front end of the paper.
