An image reading apparatus has an automatic original transporting device, a scanning device for effecting exposure scanning of the original while moving relative to the original over a platen glass, and a control circuit for controlling the scanning device to cause it to effect exposure scanning while moving it in a direction opposite to the direction in which the original is being transported. An image forming apparatus which includes the above image reading apparatus is also provided.

Image forming apparatus with increased throughput from simultaneous scanning and original feed

An image forming apparatus includes a photosensitive member, a transfer mechanism, a fixing mechanism, a sheet ejection mechanism, and a driving source. The transfer mechanism including a transfer roller that transfers a toner image carried on a photosensitive member onto a recording sheet. The fixing mechanism fixes the toner image onto the recording sheet with heat and pressure. The fixing mechanism includes a fixing roller and a pressure plate, and applies heat and pressure to the toner image on the recording sheet when the recording sheet is caused to pass through a fixing nip portion. The sheet ejection mechanism ejects the recording sheet and includes sheet ejection rollers. The driving source drives the photosensitive member, the transfer roller, the fixing roller, and the sheet ejection rollers to transfer the recording sheet at a linear speed in a substantially constant manner from the photosensitive member through to the sheet ejection mechanism.

Method and apparatus for image forming capable of effectively performing a fixing process

A device for winding a continuous strip of roll-fed material, reeled off a mother roll, sequentially onto several winding tubes. The winding tubes are mounted on rolling spindles provided on a rotatable carrier mount that permits timed angular rotation of the winding tubes through various stations in which the winding tubes are processed and wound with material. The rolling spindles are preferably mounted at essentially identical angular distances. Two drive units drive the rolling spindles individually or in groups, so that neighboring rolling spindles are operated by different drives. Accordingly, the rotational speeds of winding tubes sequentially entering a winding station may be independently controlled. The winding device thus can achieve greater winding speeds than other prior art winding devices. A glue application device that applies glue helically around the winding tubes is also provided. Additionally, a cutting device is provided for perforating the strip of material to provide a cleaner cut than in prior an devices.

An original-transporting rotor configured to transport an original to an image-reading section and, after correcting skew of the original, to an original-transporting section capable of opening and closing relative to the image-reading section is provided. The original-transporting rotor is supported so as to define a variable angle with a light source provided in the image-reading section. When the original-transporting section is closed, an original-transporting mechanism is positioned by position regulating members.

Image-reading apparatus

An electrophotographic apparatus incorporating a sorter device formed by a double pair of driving rollers for ejecting sheets from the apparatus and delivering them into a collecting bin, the two roller pairs acting on the side edges of the sheets at selectively controllable velocities to selectively produce an angular deflection of the outgoing sheets in either of two directions and their delivery into the collecting bin in different positions rotated from each other, the bin having an opening dihedral with side walls which define the maximum amounts of imparted deflection for the two positions.

Electrophotographic apparatus incorporating offset stacking

PURPOSE:To open and close automatically an original cover and to eliminate trouble in opening and closing the original cover manually, and to prevent miscopying from is caused and an original from being left forgetfully by providing a main device body with a driving means which opens and closes the original cover CONSTITUTION:When a copy is taken, the original cover 3 is closed by a motor 9 without fail Consequently, such miscopying that part of the contents of the original S is not copied on a form owing to the shifting of the original during the copying operation when the copying operation is performed with the original cover 3 unclosed and an image formed on the form becomes unsharp due to light from an exposing mechanism which is transmitted through the original S is prevented When copies as many as the preset number of forms are taken and the copying operation is finished, the motor 9 is driven under the command of a motor control circuit to rotate the original cover 3, thereby opening an original platen 2 Consequently, the original is removed from the original platen 2 Thus, the original cover 3 is opened securely by the motor 9 after the copying operation, so the original S is prevented from being left on the original platen 2
