    摘要: In a multiple QAM system in which a pair of quadrature-phase carrier signals is modulated by a first and a second input digital signal, each representative of N or less levels, into a quadrature-phase amplitude modulated signal having M signal points on a phase plane where M is equal to N.sup.2, a code converting unit (41) converts the digital signals according to a predetermined rule into a first and a second modulating signal for use in modulating the carrier signals with the M signal points arranged approximately at a circle of a diameter which is shorter than a diagonal of a square of a side corresponding to the N levels. In a counterpart demodulating system, a pair of demodulated signals is derived from the amplitude modulated signal and converted into reproductions of the respective digital signals according to an inverse of the predetermined rule.

    摘要: An original to be copied is placed in a given position. An exposure optics including a movable part is employed to focus an optical image of slitwise segment of the original on a photosensitive member. The photosensitive member moves in a given direction and at a given speed throughout the exposure. The location where the image of slitwise segment of the original is focused moves through the space of the arrangement at a given speed and in a direction opposite from the direction of movement of the photosensitive member throughout the exposure. Consequently, the location corresponding to the initiation of the exposure is situated downstream as viewed in the direction of movement of the surface of the photosensitive member while the location corresponding to the end of the exposure is situated upstream as viewed in the same direction. Upon termination of the exposure, the photosensitive member continues its movement which is the same as during the exposure while the movable part of the exposure optics returns to its start position.

    摘要: A cylindrical electrode (26) is disposed in a tubular housing (22) and applied with an electric potential opposite in polarity to a charge on usable toner particles removed from a photoconductive drum (13). A fur brush (21) bifunctions to remove the toner and foreign matter from the drum (13) and create an air flow which carries the toner and foreign matter through a passageway (41) defined between the housing (22) and cylinder (26). The foreign matter is carried into a foreign matter chamber (29) by centrifugal force while the toner adheres to the cylinder (26) which is rotated in the same direction as the air flow. The toner is carried past a blade (34) which extends closely adjacent to the cylinder (26) into a toner recovery chamber (31) from which it is scrapingly removed from the cylinder (26) and recycled.

    摘要: A scanning head moves relative to a document platen and a photoconductive member for scanning a document supported on the platen and imaging the photoconductive member. The scanning head has a slit which constitutes an exposure aperture and has a width which is predetermined for optimum image formation. The speed of movement of the scanning head is varied to adjust the image intensity to the desired value depending on the characteristics of the document. The scanning head is connected to a belt which is trained around pulleys in such a manner that driving the belt in one direction produces reciprocation of the scanning head, the scanning head being driven in one direction for one scanning operation and in the opposite direction for a subsequent scanning operation.

    摘要: In a flexible wiring board for use in, for example, a liquid discharge head, wires disposed on a substrate in parallel are covered with a film material. The flexible wiring board is bendable towards one of a front surface side and a back surface side of the substrate and includes a bending line. The bending line is formed by bending the flexible wiring board along a bending direction crossing a longitudinal direction of the wires. The bending line contains the wires. Both ends of the flexible wiring board in the bending direction are located on the bending line. A distance between one of the wires located closest to one end of the flexible wiring board and the one end is larger on the bending line than in another part of the flexible wiring board. Accordingly, even if the flexible wiring board is bent at a small bend radius, peeling does not easily occur between a base film and a cover film.
