An image forming system includes: an image forming apparatus configured to form an image on a recording medium; a post-processing apparatus configured to perform post-processing on the recording medium on which an image is formed by the image forming apparatus; a relay apparatus having a function of changing a transport speed of the recording medium on which an image is formed by the image forming apparatus to a transport speed of the post-processing apparatus and transporting the recording medium to a subsequent stage; and a charge eliminating apparatus configured to perform charge elimination on the recording medium that is charged, by reducing a charge amount of the charged recording medium, and the charge eliminating apparatus is provided at a stage that is after the relay apparatus and before the post-processing apparatus.

The conveyance guide unit is provided with a guide member, a supporting frame, and an external cover. The guide member guides a sheet, which is discharged from a sheet discharge port of the image forming apparatus or from a sheet discharge port of a relay conveyance device installed in the image forming apparatus, to the sheet carrying-in port of a post-processing device. The supporting frame supports the guide member. The external cover is fixed to the supporting frame; the external cover covers an upper part of the guide member and side parts of the guide member in a traverse direction of a sheet conveyance path, which is perpendicular to a sheet conveyance direction. The external cover has an upper surface serving as an extension part of a discharge tray part of the post-processing device, the extension part being extended downstream, in a sheet discharge direction.

There is provided an image recording apparatus having a housing having a front wall and a rear wall, and a right wall and a left wall defining an internal space of the housing, a sheet roll holder configured to hold a sheet roll, a supporting member configured to support the sheet roll, the supporting member extending in an axial direction of the sheet roll and being supported by the sheet roll holder, a sheet conveyer arranged in an internal space of the housing, the sheet conveyer being configured to convey a sheet unwound from the sheet roll, and a recording device configured to record an image on the sheet unwound from the sheet roll and conveyed by the sheet conveyer. The sheet roll holder is configured to be slidable with respect to the housing so as to be detachable from and attachable to the housing.

A recording apparatus includes a recording unit, a discharge unit that discharges a medium on which recording is performed by the recording unit, and a medium receiving unit that receives a medium discharged by the discharge unit, and a medium can be fed to an optional device attached to an apparatus main body from the discharge unit. The discharge unit includes a discharge roller that discharges a medium, a forming unit that forms a medium to be discharged, and a detection unit that detects a stacking height of a medium stacked on the medium receiving unit and is located at a position where the detection unit interferes with the optional device when the optional device is attached, the detection unit and the forming unit are integrally configured, and the detection unit and the forming unit are configured to be integrally attached to and removed from the apparatus main body.

An image forming apparatus includes a housing, a toner image forming portion, a foil transfer unit, a sheet tray, and a discharge portion. The toner image forming portion is provided in the housing and configured to form a toner image on a sheet. The foil transfer unit is configured to superpose a foil with a surface of the sheet. The sheet tray is installable in the housing in an inserting direction and configured to accommodate a sheet to be supplied to the toner image forming portion. The first discharge portion is configured to discharge the sheet from the foil transfer unit to the outside of the housing in a discharging direction opposite to the inserting direction. The second discharge portion is configured to discharge the sheet from the toner image forming portion to the outside of the housing without passing through the foil transfer unit in the discharge direction.

A sheet processing apparatus sandwiches a sheet media in a two-ply sheet in which two sheets are overlaid and bonded together at a portion of the two-ply sheet. The sheet processing apparatus includes a fixing device, a tray, and a roller. The fixing device applies heat and pressure to the two-ply sheet. The tray is disposed downstream from the fixing device in a conveyance direction of the two-ply sheet, to stack the two-ply sheet. The roller conveys the two-ply sheet vertically downward toward the tray after the two-ply sheet passes through the fixing device.

A printer extension kit that modifies a printer to receive and output longer pieces of paper. The printer extension kit includes an input extension part, an output extension part, and an output extension clip. The paper tray of a printer is extended by the input extension part allowing the printer to hold longer pieces of paper. The input extension part is attached to the paper tray of a printer. The output extension part allows a printer to output longer pieces of paper. In more detail, the output extension part prevents longer pieces of paper from falling of the catch tray of a printer. The output extension part is attached into the catch tray of a printer. The output extension clip provides another means for a printer to output longer pieces of paper. In more detail, the output extension clip is attached along the output paper catch of a printer.

An image forming apparatus includes a printing device, a rotator, an upstream support stand. The printing device prints an image on a plate-shaped printing medium. The rotator rotates while nipping the plate-shaped printing medium and conveys the plate-shaped printing medium to the printing device. The upstream support stand supports the plate-shaped printing medium at a position upstream from the rotator in a conveyance direction of the plate-shaped printing medium and includes a mount. The mount is detachably attached to the rotator.

An image forming apparatus includes: a first opening/closing member that can move between a first opening position in which the first opening/closing member opens an inside of a body of the image forming apparatus, and a first closing position in which the first opening/closing member closes the inside of the body of the image forming apparatus; a second opening/closing member that can move around a rotation shaft and between a second closing position in which the second opening/closing member closes an opening formed in the first opening/closing member, and a second opening position in which the second opening/closing member opens the opening, the second opening/closing member being removably attached to the body of the image forming apparatus; and a supported portion that is provided in the first opening/closing member so as to be supported on a support portion of the second opening/closing member, as defined herein.

An object processing machine for processing a plurality of objects, the machine comprising: a plurality of processing modules, each processing module having a modular structure co-operable with the modular structure of another processing module to form a modular assembly constituting the object processing machine; each processing module being operable to perform a corresponding processing operation on an object and being provided with at least one transfer unit located at a respective port of the processing module; each transfer unit being arranged to transfer an object to or from the corresponding processing module and/or to or from a transfer unit of another processing module of the modular assembly; the transfer units being arranged to co-operate with one another and/or with another processing unit such that objects can be guided from an input of the machine to an output of the machine via a plurality of different transport pathways through the machine, wherein the transport pathway taken by a said object being processed corresponds to the pre-determined processing operations to be performed on the said object. A method of processing a plurality of objects using such a machine is also described.
