    摘要： A multi-beam optical scanning apparatus includes a semiconductor laser array slanted relative to a sub-scanning direction and emitting a plurality of optical beams; a coupling lens converting a shape of each optical beam emitted from the semiconductor laser array; and an aperture with an opening having a size of Am×As, arranged after the coupling lens in a direction in which the optical beam progresses, where Am is a dimension of the opening in a main scanning direction and As is a dimension of the opening in the sub-scanning direction. When a length in the main scanning direction of a contour line defined by 1/e2 strength of a maximum strength of an optical beam at the position of the aperture is Lm, and a length in the sub-scanning direction of the contour line defined by 1/e2 strength of the maximum strength of the optical beam at the position of the aperture is Ls, the following conditional expressions are satisfied: Am

    摘要： An optical scanning apparatus including a pulse modulation mechanism, a laser light source, a light deflecting mechanism, and a scan-imaging device. The pulse modulation mechanism performs a pulse modulation to input image data to output pulse-modulated image data. The laser light source generates a laser light beam according to the pulse-modulated image data. The laser light beam has a wavelength variation smaller than 2.0 nm per one pulse of the laser light beam. The light deflecting mechanism converts the laser light beam into a scanning laser light beam. The scan-imaging device condenses the scanning laser light beam into a scanning light spot on a surface to be scanned.

    摘要： A printing apparatus includes a print head section having a nozzle for discharging ink; a paper feed section for feeding paper in a paper feed direction; a movement section for reciprocally moving the print head along a track formed in a direction perpendicular to the paper feed direction; a maintenance section for performing a maintenance operation on the nozzle; a case for accommodating the above-mentioned sections; a cover attached to the case in an openable and closable manner; a detection section for detecting open and closed states of the cover and outputting detection signals representative of the open and closed states of the cover; and a control section for controlling drive of the movement section and the maintenance section according to the detection signals output by the detection section. The maintenance section includes two maintenance stations mounted on both ends of the track, and the control section gives an instruction such that the print head moving to one of the maintenance stations is stopped at a stop position established on the track, in response to the detection signal representative of the open state of the cover.
