摘要： PROBLEM TO BE SOLVED: To provide a compact structure and rapid method for calibrating a document scanner. SOLUTION: The structure has a substantially cylindrical calibration casing 50 having a center axis and an outer face, a brightness calibration area 54 surrounding part of the outer circumferential surface, a document width detection area 56 surrounding a 2nd part of the outer circumferential surface, and a back support 60 that surrounds a 3rd segment of the outer circumferential surface of the casing. A driver selectively positions the casing at various rotational positions so that various areas of the outer face of the cylinder face the optical elements of the scanner.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method useful for acquiring and carrying a sheet in a printer. SOLUTION: A feeder 120 includes a vacuum duct capable of joining a vacuum source so that negative pressure can exist in an opening of a plenum. A stack height sensing arm 118 can movably control a slide plate 104. The slide plate 104 includes two openings 110 for a falling box, and the falling box 108 is slidably arranged in its openings. A grid 114 can be formed in the respective openings 110. Since the opening in the plenum is fluid-communicated with the openings 110 of the slide plate 104, the negative pressure existing in the opening in the plenum can also be made to exist in a space of the falling box by the falling box 108.

摘要： PROBLEM TO BE SOLVED: To provide a medium stack sheet-fluffer device for preventing a plurality of cut sheets from being fed together due to mutual adhesion of material when feeding the cut sheets at high speed.
SOLUTION: A first fluffer aperture pattern includes two respective apertures 110, 120. In accordance with rotation of an aperture plate around an aperture plate shaft 106, the respective apertures are momentarily directed to a jet 60 of a fluffer to allow a plenum flow 200 to momentarily pass through the aperture (110 or 120) and to enter the jet 60 of the fluffer. As a result, a jet flow 300 of a momentary medium stack-fluffer is formed. Then, the jet 60 of the fluffer gives the jet flow 300 of the momentary medium stack-fluffer to one or more arbitrary medium stack side surfaces 5, 6, 7, 8 included in a medium stack 2, as well as an outer edge part of the medium stack, a surface, or the side surface 8.

摘要： PROBLEM TO BE SOLVED: To provide a compact structure and rapid method for calibrating a document scanner.
SOLUTION: The structure is provided with a substantially cylindrical calibration casing 50 having a central axis and an outer surface, with a brightness calibration section 54 of the outer surface encompassing a portion of the outer circumferential surface, a document width detection segment 56 encompassing a second portion of the outer circumferential surface, and a document holding element 60 encompassing a third segment of the outer circumferential surface of the casing. A drive unit selectively positions the casing at various rotational positions such that the different outer surface segments of the cylinder face the optical element of the scanner.
