A both-face automatic original feeding apparatus wherein a plurality of originals having images on their first and second surfaces are successively supplied from an original stacking portion to a predetermined position for reading an original, and each original is reversely rotated through a switch-back path after the first surface of the original passes through the predetermined position, thereby supplying the original to the predetermined position again to direct the second surface of the original to the predetermined position. In such a feeding apparatus, there is provided an introduction path for directing the original supplied from the original stacking portion to the predetermined position; a first discharge path for directing the original to the switch-back path after the original passes through the predetermined position; a surface reverse path for directing the original from the switch-back path to the predetermined position after reversing a first surface and a rear surface of the original; and a controller for controlling the apparatus in such a manner that a preceding original is switched back to convey it in the surface reverse path while a succeeding original is being passed through the predetermined position, and, when a trailing end of the succeeding original leaves the predetermined position, a tip end of the preceding original reaches the predetermined position.

Both-face automatic original feeding apparatus

An original document feeding apparatus introduces an original document to a reading position to read image information of the original document, provided is a first delivery passage for delivering the original document from the reading position, a second deliverying passage branching off from the first delivery passage, and conveyance route switching unit selectively movable between a first position for introducing the original document to the first delivery passage and a second position for introducing the original document to the second delivery passage, each without projecting in the first delivery passage.

Sheet feeding apparatus and image forming apparatus

An automatic original feeding device has a mounting unit for mounting originals, a first sheet conveying path for conveying an original mounted on the mounting unit to a predetermined position, and a second sheet conveying path for guiding the original output from the predetermined position to a discharging unit. The device can be opened to expose the first and second sheet conveying paths. The device also includes display units, each provided in the vicinity of the corresponding one of the first and second sheet conveying paths, for displaying information about originals remaining in the first and second sheet conveying paths.

Automatic original feeding device with jam recovery displays

In order to supply a sheet to an image forming device, there is provided a manual insertion guide for supporting a manually inserted sheet and a cassette for supporting a sheet to be automatically supplied, and a guide portion for guiding the sheet fed from the cassette is integrally formed with the manual insertion guide. The manual insertion guide has side regulating members for regulating the side edges of the manually inserted sheet.

Sheet supply apparatus having manual insertion guide

An image fixing apparatus includes a heater; a film movable together with a recording material in contact with the heater; a pressing member for establishing press-contact between the heater and the film and between the film and the recording medium; and a shutting device for shutting power supply to the heater upon release of the pressure contact.

Image fixing apparatus with energy cut-off

An image heating device includes a heater; an endless belt movable together with a recording material carrying an image; wherein the image carried upon the recording material is heated through the endless belt by heat from the heater; a lateral shift controller for controlling the endless belt to shift laterally in the alternating directions within a predetermined range; and a lateral shifting range controller for controlling the range by the lateral shift controller.

Image heating device employing endless belt

An image forming apparatus includes image forming device for forming an unfixed image on a recording material; a fixing device for fixing the unfixed image on the recording material, the fixing device including a heater which is stationary in use, a film in sliding contact with the heater and a pressing member cooperative with the film to form a nip for receiving the recording material, and an opening portion for opening the apparatus for permitting jam clearance operation of the recording material in the fixing device. The pressing member and the film are separated from each other in association with opening of the opening portion.

Image forming apparatus having opening mechanism for jam clearance

An image fixing apparatus includes a heater; a film in contact with the heater, wherein heat from the heater is applied through the film to a toner image on an image supporting member; and wherein the film is in contact with an entire heat generating area of a heater.

Image fixing apparatus for heat fixing a toner image through a film

An image heating apparatus includes a heater; a film movable in contact with a recording material carrying an image, wherein the image on the recording material is heated by heat from the heater through the film; a driving rotatable member for driving the film; wherein the driving rotatable member has a heat insulative surface layer.

Image heating apparatus using film driven by rotatable member

An electrophotographic copying apparatus is provided with a first body and a second body, the first body having a photosensitive member, a light source for exposing an original, an original supporting table movable relative to the light source with the original supported thereon, and a first optical system for projecting a first image information light reflected from the original onto the photosensitive member. The second body has a second optical system for projecting a second image information light onto the photosensitive member in the first body. Two copying modes are provided: a first mode for copying by the first image information light, and a second mode for copying by the second image information light. In the second mode, a controller positions a shutter member for blank exposure in the optical path in its retracted position prior to the copying in the second mode. Thus, solving the optical problems on the copying apparatus side and on the apparatus side for operating the recording medium and the higher functionalization of an optical system and/or the movement range of the movable original supporting table is changed during the original copying and during the copying of the recording medium to thereby enable the efficient use of the space.

Electrophotographic copying apparatus for copying an original placed on

An image fixing apparatus includes a heater; an endless film through which a toner image on a recording material is heated by heat produced by the heater; and a controller for controlling a position of the endless film in a direction perpendicular to a rotating directon of the endless film.
