Abstract: An image-forming apparatus includes a first unit configured to form an image on a recording medium, a second unit configured to open/close relative to the first unit, and an instructing unit configured to perform an instruction for causing the image-forming apparatus to execute a predetermined operation, wherein the image-forming apparatus is disabled from executing the predetermined operation regardless of whether instruction is performed by the instructing unit when the second unit is in an opened state, and wherein the first unit forms an image on a recording medium regardless of whether the second unit is in an opened state.

Abstract: An image reading device includes a memory unit for storing positional information of a sensor for moving by a drive unit to read an image of a document and a control unit for controlling the drive unit to move the sensor based on the positional information stored in the memory unit. The control unit drives the drive unit by an amount of driving sufficient for an image reading unit to move in a predetermined direction to abut the stop members, controls the drive unit to move the sensor so as to detect the position mark, and updates the positional information of the memory unit to a predetermined initial value based on the detection of the position mark by the sensor. The image reading device can store data of a reference position promptly even if a photo-interrupter is not provided when the data of the reference position is not stored in a memory unit.

Abstract: An image reading apparatus, wherein it comprises a conveying unit for conveying an original, a reading unit for optically reading the information recorded in the conveyed original at a predetermined reading location, an original pressing unit for pressing the original to the reading unit, and a color reference member used as a color reference a the time when the information is read by the reading unit, and wherein the color reference member is arranged between the reading unit and the original pressing unit and the pressing location of the original to the reading means by the original pressing unit is disposed at a location within the original conveying region and other than the reading location.

Abstract: The present invention relates to an image reading recording apparatus comprising an image reading section for reading an image on an original document, an image recording section for recording an image on a recording medium and a control section for controlling the entire apparatus. The control section is disposed below the image reading section and above the image recording section and disposed on a rear side of an apparatus body.

Abstract: An image feeding apparatus for feeding sheets by separating sheets one by one by a separating device has a pickup arm and a stopper. The uppermost document of stacking documents to be copied contacts and downwardly press down the pickup arm, and then the pickup arm and the uppermost document downwardly press down the stopper so as to make a passage of the uppermost document. After the uppermost document passes through, the stopper ascents by gravity in response to elevation of the pickup arm. The stopper can be reliably operated by a simple and low-cost construction.

Abstract: A sheet feeding apparatus having a stocking plate on which a plurality of sheets are stackable, a separating device for separating the sheets stacked on the stocking plate one by one by a pair of pressure contact members, a feeding device for feeding the sheets, and a pressure releasing device for releasing the pressure contact of the pair of pressure contact members has a returning device for acting on the pressure releasing device to thereby return the pair of pressure contact members to their pressure contact state after a single-sheet feeding is terminated when the sheets are fed with the pair of pressure contact members pressure-released by the pressure releasing device.

Abstract: The present invention provides a sheet separating and conveying apparatus for separating stacked sheets and for conveying a separated sheet, comprises a sheet convey means for conveying the sheet, a friction means disposed in a confronting relation to the sheet convey means, a biasing means for urging the sheet convey means and the friction means against each other, a preliminary convey means adapted to be urged against the sheet convey means at an upstream side of a contact position between the sheet convey means and the friction means in a sheet conveying direction, and a friction releasing means for separating the sheet convey means and the friction means from each other, and wherein, when the sheet convey means and the friction means are separated from each other by the friction releasing means, the preliminary convey means is maintained in a condition that the preliminary convey means is urged against the sheet convey means.

Abstract: An image forming apparatus has an image reading portion provided in an upper portion of an apparatus body on the side of its front surface, an optical signal generating portion provided in rear of the image reading portion, an image forming portion disposed downwardly of the optical signal generating portion, a fixing portion provided in the vicinity of a lower portion of the apparatus body on its front surface side, a sheet discharge portion, disposed between the image forming portion, the optical signal generating portion and the image reading portion, to which to discharge the record sheet onto which a toner image is fixed by the fixing portion, and an opening/closing cover rotated integrally with the image reading portion and the sheet discharge portion. When the opening/closing cover is opened, the image forming portion is exposed and a part of a sheet carry path extending from the fixing portion to the sheet discharge portion is made open.

Abstract: The present invention provides a sheet supplying apparatus with a sheet stacking plate on which a plurality of sheets can be stacked, a sheet supply unit for successively supplying the sheets rested on the sheet stacking plate one by one, and a sheet regulating device for regulating a tip end of the sheet stack rested on the sheet stacking plate. The sheet supply unit has a rotary member and the rotary member has a cooperation portion for switching regulation and release of the tip end of the sheet stack by the sheet regulating device. Further, when the rotary member is rotated in a sheet conveying direction, the sheet regulating device is shifted by the cooperation portion to a position where the regulation of the tip end of the sheet stack is released.
