Abstract: A device for reading color images comprises an optical input unit, an optical resolution unit and a photoelectric conversion unit. The optical input unit has a constant valid reading width for inputting three colors of RGB at the same time. A first optical path radiates a RGB light inputted from the optical input unit. A second optical path radiates a RGB light inputted from the optical input unit in a path different from the first optical path. A third optical path radiates a RGB light inputted from the optical input unit in a path different from the first and the second optical path. The optical resolution unit receives three RGB lights that are incidented into the optical input unit through the first, the second and the third optical path to resolve one of the three RGB lights into a R light, resolve one of the remaining two RGB lights into a G light and resolve the other one into a B light.

Abstract: A serial electrophotographic apparatus has a carriage which is translated in a direction perpendicular to a direction in which recording paper is transported, a processing part effects electrophotographic printing, and a fixing unit effects fixing, wherein a fixing roller is heated by an induction coil according to an induction heating process, and a current supplied to the induction coil is cut off by a temperature fuse being blown when the temperature of the induction coil rises above a predetermined level. The induction coil has a configuration including multiple flat winding layers serially connected together and wherein ends of the induction coil are led out from the center of the windings so that temperature rise is restrained.

Abstract: A carriage is constructed such that a processing part and a fixing part are fitted to a sliding part, wherein a frame on which an exposer and a process motor are mounted is rotatably fitted to the sliding part, and a housing which accommodates the fixing part and the processing part not including the exposer is rotatably and detachably fitted to the frame.

Abstract: A conveying unit conveys a recording sheet. A carriage comprises a process unit for forming a latent image and developing it so as to produce a developed image on an image carrier having a rotation axis parallel to a direction along which the conveying unit conveys the recording sheet, and a fixing unit using a fixing member for fixing the developed image to the recording sheet after the developed image has been transferred to the recording sheet. A transfer unit transfers the developed image produced on the image carrier to the recording sheet. A moving unit moves the carriage on the transfer unit along a direction perpendicular to the direction along which the conveying unit conveys the recording sheet, the carriage thus repeating a go-and-return operation in which the carriage fixes a line of the developed image onto the recording sheet while moving and then returns to a predetermined position. A heating unit heats the fixing member to a predetermined temperature.

Abstract: A processing part mounted in a carriage for effecting printing when translated in a direction perpendicular to a direction in which recording paper is transported includes a developing unit, the developing unit including a toner chamber and a toner cartridge detachably coupled to the toner chamber.

Abstract: A serial printer has a transport mechanism for transporting a recording sheet in a sheet transport direction, a process part including an image bearing member with a rotary shaft which extends in a direction parallel to the sheet transport direction for forming a latent image on the image bearing member by charging the image bearing member and developing the latent image into a developed image, a fixing unit for fixing the developed image on the image bearing member onto the recording sheet, and a carriage movable in a carriage moving direction perpendicular to the sheet transport direction and supporting the process part and the fixing unit. The process part and the fixing unit are independently movable on the carriage.

Abstract: An image forming device includes a conveying unit for conveying a recording sheet in a first direction, a process unit for forming a latent image of static charge and developing said latent image into an image on an image-holding body, which rolls on said recording sheet in a second direction perpendicular to said first direction so as to transfer said image on to said recording sheet, an image-fixing unit for fixing said image on said recording sheet, a carriage carrying said process unit and said image-fixing unit, which carriage moves in said second direction, and a recording-sheet fixing unit for holding said recording sheet when said process unit and said image-fixing unit operate as said carriage moves.

Abstract: A serial printer has a plurality of printing assemblies each comprising, a transport mechanism for transporting a recording sheet in a sheet transport direction, a process part, including an image bearing member with a rotary shaft which extends in a direction parallel to the sheet transport direction, for forming a latent image on the image bearing member by charging the image bearing member and developing the latent image into a developed image, a fixing unit, including a first fixing member, for fixing the developed image on the image bearing member onto the recording sheet by the first fixing member, at least one printing carriage movable in a carriage moving direction perpendicular to the sheet transport direction and supporting the process part and the fixing unit, and a transfer unit for transferring the developed image formed on the image bearing member onto the recording sheet that is interposed between the transfer unit and the printing carriage.

Abstract: This invention relates to an electrophotographic device in which a latent image is formed on a recording drum by toner material. The invention prevents unused toner from being attached to the recording drum so that the quality of an image formed can be improved. In this invention, a carriage is conveyed in a perpendicular direction to a feeding direction of recording paper for printing thereon. A developing roller of a developing device mounted in a process portion is wider than an effective imaging area of the recording drum and is narrower than a charged area thereof. Also, sealing members can be provided at both end surfaces of the developing roller.

Abstract: The quality of an image can be improved by adjusting the print. When a carriage of an electrographic device is conveyed in a perpendicular direction to the feeding direction of the recording paper for exposure, development and photographic fixing, temperature and/or himidity is detected to determine an absolute humidity. The feeding amount of the paper is altered. A new feeding amount of the recording paper is determined in consideration of the altered feeding amount of the recording paper. Accordingly, the effect of shrinkage of the recording paper can be avoided, each image line can be arranged continuously and the quality of the image can be improved.
