摘要： A printing apparatus comprising: an elongate platen; a guide member extending parallel to the platen; a carriage slidably movable on the guide member; a printing head mounted on the carriage; an image reading device including an image-reading portion for reading images on a recording medium on the platen, the image-reading portion being movable between a reading position adjacent to the recording medium, and a retracted position spaced from the reading position in a direction away from the recording medium; and a device for engagement of the image reading device with the carriage, to permit the image reading device to move together with the carriage. The image reading device may be supported pivotally by the guide member in the form of a rod. The carriage may have a stopper abutable on the image reading device to determine the reading position of the image-reading portion. The apparatus may further comprise a member for checking optical sensitivity of the image reading device. This checking member has a reflector which is selectively placed in an operative position opposite to the image-reading portion, and an inoperative position misaligned with the image-reading position.

摘要： An image reader for reading images on a surface of a medium, having a feeding device for feeding the medium, carriage movable in a direction perpendicular to the direction of feed of the medium, a driving device for moving the carriage, and a reading head mounted on the carriage for reading the images on the medium surface. The image reader comprises an area setter for setting a reading area on the medium surface within which the images are read by the reading head. The reading area is set while the reading head is moved relative to the medium by the feeding and driving devices. The image reader further comprises a controller for controlling the feeding and driving devices and the reading head, to cause the reading head to read the images within the set reading area while the reading area is scanned by the reading head.

摘要： A partition wall for separating a developing chamber from a toner agitating chamber in an electrostatic developing device includes a high wall portion confronting a toner discharge opening of a toner cartridge, and low wall portions formed on either side of the high wall portion. Toner is discharged from the toner discharge opening of the toner cartridge into the agitating chamber. Toner is then sent over the partition wall and into the developing chamber by rotation of an agitator in the agitating chamber. Toner in the central portion of the agitating chamber goes over the high wall portion, and toner in the side portions of the agitating chamber goes over the low wall portions. Accordingly, a uniform amount of toner is supplied to all points along the length of a developing sleeve in the developing chamber, and hence to all points along the length of a photosensitive drum confronting the developing sleeve.

摘要： An optical guide device in an optical reading system incorporated in a facsimile device, copying machine, image scanner and the like includes an array of LEDs and a light guide plate. When the light guide plate is cut along the longitudinal axis to give a cross-section in which the thickness appears, the cross-section is in a tapered shape and the thickness of the light guide plate at the side confronting the light array increases toward the opposite side facing the document. The light emerging from the light guide plate is high and uniform in light intensity level, so that a CCD unit picks up the light reflected from the document with high accuracy.

摘要： A facsimile apparatus includes a light emitting unit disposed downstream in the direction of feed of a document with respect to a normal plane perpendicular to the document surface on a reading line. Outgoing beams for reading travel rearward in a substantially horizontal direction. Incoming beams from the light emitting unit are reflected on the reading line on the document surface and are supplied as the outgoing beams for reading to a light sensing unit. Consequently, it is possible to reduce the height of the front portion of the facsimile apparatus so as to increase a degree of freedom in designing while enhancing reliability in reading the document.

摘要： A pair of discharge rollers is provided at a position most downstream in a conveying direction of a sheet conveying path defined by guide surfaces. The discharge rollers discharge a sheet from the sheet conveying path. A discharge chute portion, including upper and lower discharge guides, guides the discharged sheet toward a discharge tray. An elastic support piece is provided in the discharge chute portion and elastically urges a trailing edge of the discharged sheet toward the upper discharge guide. The pair of discharge rollers is arranged such that a direction in which the drive roller contacts the follower roller is inclined toward upstream in the conveying direction with respect to a direction of a normal line of a lower one of the guide surfaces that is located in the sheet conveying path at a position the most downstream in the conveying direction.
