摘要： A multi-functional peripheral allows a user to select a productivity priority mode or an image quality priority mode. In the productivity priority mode, a scanner performs a reading operation without moving first and second carriages in a sub-scanning direction, a foreign object image removing processing is executed in accordance with image data obtained by the reading operation, and image forming is performed in accordance with the image data applied with image processing. In the image quality priority mode, the first and second carriages are moved from a reading position P to a reading position P′ at which the foreign object does not adhere to a reading slot, the scanner performs the reading operation, and an image forming is performed in accordance with image data applied with image processing not including the foreign object image removing processing.

摘要： An image processing apparatus has a display to display color images and a storage to store color image data. A first preview controller causes the display to display a color preview image based on stored color image data. A character-area extractor extracts a character area from the stored color image data and a color-designation acceptor accepts a designated color newly set in the extracted character area. A second preview controller changes a color of the extracted character area extracted in the preview image to the accepted designated color, and causes a display of the changed preview image. A decision-instruction acceptor accepts an instruction to set the designated color. A color-change processor responds to the accepted instruction by the decision-instruction acceptor to change information representing a color of the stored color image data to allow the color of the extracted character area to be changed to the accepted designated color.

摘要： The present invention provides an image reading device, an image printing system and image forming device in which variation in light intensity caused by the continuous lighting time of an exposure lamp serving as a light source for reading an original is prevented, a read image is prevented from deteriorating and wasteful power consumption is prevented. The exposure lamp is turned off after a predetermined time has passed from a time when the original finishes passing through a reading position or the original is conveyed to a standby position. Alternatively, the exposure lamp is turned off without setting the predetermined time in a group-copy mode.

摘要： A direct current motor is comprised of an armature, magnets arranged to face each other through the armature, a commutator and brushes. The armature has a core and a plurality of coils wound on the core. Each magnet has a main part and an extension extending form the main part. The main part has an angular interval which corresponds to an interval of winding each coil, so that the extension is positioned outside the coil in the circumferential direction. During the commutation period of the coil, that is, during shorting of the coil by the brush, the amount of magnetic flux passing through the coil is changed by the extension of the magnet. Thus, an induction voltage is generated in the coil to counteract to a reactance voltage of the coil.

摘要： A sheet-through document reader for reading an image formed on a surface of a document original being transported through a reading position. The document reader includes: a reading mechanism for performing main scanning to scan the surface of the document original in a direction perpendicular to a document transport direction at the reading position thereby to read an optical image of the document original, and converting the optical image into image signals; an abnormal value detection circuit for determining whether or not any abnormal value is present in image signals obtained by performing the main scanning by means of the reading mechanism, for example, before the document is read; and a reading position shifting mechanism for shifting the reading position in the document transport direction when the abnormal value detection circuit detects an abnormal value.

摘要： An automatic document feeding apparatus of the present invention is arranged such that a transportation unit 24 (enclosing a pre-feeding roller 25, a pair of paper feeding rollers 26, a pair of resist rollers 27, a reading section 28, a pair of discharging rollers 29, etc.) is attached to a framework member 65 (a stay 66, a front-end plate 7, a rear-end plate 68, etc.) not fixedly, but in such a manner that at least the rearward end of the transportation unit 24 is capable of displacements in a vertical direction with respect to the framework member 65. Consequently, when the framework member 65 causes deflection, such deflection caused on the framework member 65 will not adversely affect an attachment state of the transportation unit 24.

摘要： An automatic document conveyer comprising a moving frame turnably mounted on a machine housing via a hinge mechanism and a conveyer belt mechanism mounted on the moving frame. The conveyer belt mechanism includes a support frame, a drive roller and a driven roller arranged in the support frame, and a conveyer belt wrapped round the drive roller and the driven roller. The support frame of the conveyer belt mechanism is so supported as to be moved by a predetermined amount toward the side opposite to the hinge mechanism while the end of the conveyer belt on the side of the hinge mechanism reaches to the closed position after having come in contact with the transparent plate at the time when the moving frame is turned toward the closed position.

摘要： A document feeder which has a document transportation path curved with a curvature radius such that a document original is reversed and fed therethrough to a document setting surface. The document feeder further includes a pair of rollers respectively disposed inside and outside of the curvature of the document transportation path in an opposed relation and adapted to hold the document original therebetween for guiding the document original to the document setting surface. The rollers abut against each other in a position upstream of the vertex of the curvature of the document transportation path with respect to a document transportation direction.
