摘要： An integral document processing apparatus comprising an electrophotographic copying system and a facsimile transmission system. A document fed from a common document storing unit is guided selectively to a first document read unit included in the electrophotographic copying system or to a second document read unit included in the facsimile transmission system by a document feed passage changeover mechanism which is operated selectively by an operator. A document delivered to the first document read unit is copied by the electrophotographic copying system. A document delivered to the second document read unit is converted into a corresponding electric image signal, and then the electric image signal is applied to a communications line.

摘要： An electrophotocopying machine of the electrostatic latent image transfer type employing as a device for projection of images of original documents onto a photosensitive drum an optical fiber device which has a short focal length and permits efficient exposure of a narrow area of the photosensitive drum whereby the drum diameter can be small and machine height may be reduced. The electrophotocopying machine also occupies less area and makes efficient use of electrical power because use is made of a portion of a charging unit area to transmit image light to the photosensitive drum and use is also made of light from the document illumination device to erase the charge on the drum.

摘要： The copying machine employed with the projection device of the present disclosure is designed for copying a thin document which is moved directly over a transparent support, and a thick document which is moved over the transparent support through a suitable transparent plate. The projection device includes a light source for projecting light rays emitted from the light source onto the document to be copied through a first optical path formed between the light source and the document. The light rays reflected from the document are transmitted, through a second optical path formed between the document and photoreceptor, towards the photoreceptor surface. The projection device further includes a transparent correcton plate pivotally provided to move between a first position where the correction plate intrudes into the first optical path and a second position where the correction plate intrudes into the second optical path so as to correct the optical length, and to correct the intensity and distribution of the light to be projected onto the photoreceptor.

摘要： A belt-type photocopy machine in which the belt assembly is disconnectable from the belt drive and withdrawable to an external location for replacement of the belt. The belt is seamed, but the removable assembly contains belt-position-defining elements with which the seam in the belt is aligned during replacement, and the machine's copy sequence controls cooperate with the position-defining elements through synchronizing means upon reinsertion of the belt assembly so that coordination of the sequence controls and the belt position is achieved regardless of the relative positions of the belt and the sequence controls subsequent to reinsertion.

摘要： An electrophotographic apparatus having an endless electrophotosensitive belt transportable past a plurality of work stations and including paper supply and transport means and a unitary control circuit which actuates work stations and other apparatus elements in a required succession and at frequencies which vary in accordance with copy magnification required. The control circuit itself is actuated in response to signals supplied by one of several rotatory switching means which are rotated synchronously with the electrophotosensitive belt, thereby ensuring matching of belt and apparatus element action.The apparatus may further comprise detection switches which are disposed at various points along the path of travel of copy paper through the apparatus, and are actuable by passage of a sheet of copy paper, and the successive actuation of which is a necessary condition for continued actuation of the control circuit and sequential operation of work stations. Upon the occurrence of a paper jam and consequent failure of a sheet of copy paper to reach and actuate a detection switch, apparatus operation is stopped and a lamp or similar warning means indicative of the location of the paper jam is activated.
