摘要:
A photoelectric copier for reproducing an image of a document onto a recording sheet, comprising a document supporter, a conveyer for conveying the document onto the document supporter, a scanner for scanning the document on the document supporter and generating an image signal, and an image determiner for determining a density and a color of the image according to the image signal, wherein the scanner is positioned at a predetermined location in a conveyance path of the document before the document is conveyed onto the document supporter and a first scanning, wherein the image is scanned by the scanner while the scanner is stayed at the predetermined location and the document is conveyed onto the document supporter, is executed so that the density and the color are determined by the image determiner according to the image signal.

The invention provides an apparatus for transferring a toner image from a photoreceptor to a recording sheet. The apparatus includes a plurality of rollers and a belt stretched around the plurality of rollers. The belt is adapted to come in contact with the photoreceptor at a transfer area so that a recording sheet is conveyed on the belt and brought in contact with the image surface at the transfer area and that the toner image is transferred onto the recording sheet. The apparatus further includes a conductive member, disposed so as to come in contact with the belt on one of the plurality of rollers which is positioned upstream in conveying direction than the transfer area, for charging the recording sheet conveyed on the belt.

Provided is an image forming apparatus which enables quick removal of remaining sheets in the image forming apparatus via an orthogonal reverse section in case a jam occurs inside the image forming apparatus. The image forming apparatus includes a main conveyance section to convey a sheet in the image forming apparatus and to convey the sheet to an ejected sheet section; an orthogonal reverse section to receive the sheet from the main conveyance section and turn over the sheet without swapping a front edge for a rear edge of the sheet by conveying the sheet in a direction perpendicular to a sheet conveyance direction of the main conveyance section and a sheet ejection section to eject the sheet in the orthogonal reverse section outside the orthogonal reverse section along a direction to turn over the sheet by the orthogonal reverse section.

An input device, in use with a copier, for inputting image editing information corresponding to an image on a document. The device includes a platen glass having a transparent body; a scanner for scanning the image of the document through the transparent body of the platen glass; a printer for duplicating the image of the document, which is scanned by the scanner, onto a recording sheet; and an input touch panel for inputting the image editing information corresponding to the image. The input device includes a detector for detecting a pressing force toward the input touch panel and a location of operation of the input touch panel by the operator in which the input touch panel is equipped on the transparent body of the platen glass.

A sheet reversing apparatus including: a right angle reversing conveyance section which reverses front/back sides of a sheet while changing a conveyance direction of the sheet, being conveyed in a first conveyance direction, to a second conveyance direction perpendicular to the first conveyance direction; a sheet skew sensor which detects a sheet skew of the sheet being conveyed by the right angle reversing conveyance section; and a sheet skew correction mechanism which corrects the sheet skew of the sheet while the sheet is being conveyed by the right angle reversing conveyance section.
摘要:
An image-reading apparatus for reading an image formed on a document is provided which includes an automatic document feeder, a dynamic-document reading section, a static-document reading section, and a document-covering member. A light source mechanism irradiates an exposing light onto the document at either the dynamic-document reading section or the static-document reading section. A shutter member is provided which is movable between a shading position at which the shutter member blocks a portion of the emitted exposing light, and a non-shading position at which the shutter member does not block the exposing light. When the document is moved by the automatic document feeder at the dynamic-document reading section to read the image on the document, the shutter member is positioned at the non-shading position. When the document is stationarily placed on the static-document reading section to read the image, the shutter member is positioned at the shading position.

In order that the air surrounding a fixing member is prevented from entering a blowing section for blowing separation air, a wind speed setting section is provided with switchable control modes, namely, a first control mode (control mode for operating the blower fan at a wind speed for separation) and a second control mode (control mode for operating the blower fan at a low speed). This structure allows the blower fan to be controlled in conformity to any one of these first and second control modes.
