Abstract: Provided is an electric equipment capable of simply executing functions without examining an instruction manual whenever the same function is used, in the case of reading an instruction manual from a PDF, a web page and the like. A multi-function peripheral has a plurality of functions and includes a display unit displaying information relating to each function, wherein when the information relating to one function is displayed on the display unit, the multi-function peripheral generates and displays an icon in association with the one function, and receive an instruction to execute the one function through the icon.

Abstract: An image pickup apparatus includes lens barrels 12 and 13 that house an image pickup optical system L1 to L5, an image pickup element 8 that performs a photoelectric conversion of an object image, an image pickup element holding member 10 that is movable in an optical axis direction with respect to the lens barrels, guide bars 15 and 16 that guide a movement of the image pickup element holding member, and adjustment mechanisms 9a and 9b that perform an inclination adjustment of the image pickup element. Ends at an object side of the guide bars are held by the lens barrels, and ends at an image side of the guide bars are held by a cover member 14 that includes an opening 14c to operate the adjustment mechanism from an outside at the opposite side and that is connected with the lens barrels.

Abstract: A CPU includes a bus interface, a control unit, an instruction cache, a data cache, a secondary cache, an instruction decoder, an arithmetic unit, and registers. When operations can be performed only with the cache, the CPU inhibits access to external memory and stops power supply to the external memory. With this arrangement, by performing operations in the CPU without using the external memory, it is possible to realize a speedy processing and to stop power supply to the external memory, thus allowing for reduction in power consumption.

Abstract: An optical scanning apparatus comprising a plurality of light sources, a polygon mirror for deflecting beams emitted from the light sources in a main scanning direction, lenses for imaging the deflected beams on receiving surfaces and diverting mirrors for directing the beams which passed through the lenses to the receiving surfaces. In one side of the polygon mirror, three diverting mirrors are provided in an upper optical path, and two diverting mirrors are provided in a lower optical path. In the other side of the polygon mirror, one diverting mirror is provided in a lower optical path, and two diverting mirrors are provided in an upper optical path. Thereby, bows on the receiving surfaces have the same curving direction, and color displacement can be inhibited.

Abstract: An automatic groove-tracing welding system is capable of carrying out a welding operation, particularly, a welding operation involving weaving, without requiring monitoring even if conditions of a groove is different from design conditions of the groove. An image processor 3 receives an image signal representing an image of a weld zone 52 including the tip of a welding wire from a camera head 2 provided with a CCD camera, processes the image of the weld zone 52 to determine the position of a groove, calculates the positional relation of the groove with a welding torch 1, and sends a position correction for correcting the position of the welding torch 1 so that the welding path of the tip of the welding torch 1 may coincide with a predetermined middle part in the groove to a robot controller 43 for controlling a welding robot.

Abstract: In a scanning optical system in which a plurality of light beams emitted from a plurality of light sources are, after being formed into beams converging in a predetermined manner, deflected by a single deflector and are then shone, through scanning lens systems provided one for each light beam, onto a scanned surface so that the scanned surface is scanned by the light beams for image formation, at least one of the scanning lens systems satisfies the condition 0<-{(L-HH')+k}/k.ltoreq.0.2, where L represents the distance from the point of deflection of the light beam to the scanned surface, HH' represents the distance from the front-side principal point to the rear-side principal point of the scanning lens system, and k (k<0) represents the constant of proportionality defined by the formula y'=k.theta., where y' represents the image height on the scanned surface in the main scanning direction, and .theta.

Abstract: A light beam scanning optical apparatus which writes two lines at one scan on a photosensitive member with light beams emitted from laser diodes. The light beams are combined at a beam splitter. The beam splitter is supported on a surface including a semitransparent layer by total three balls provided on a base block.

Abstract: A copying zoom lens system is provided with from the original side a first lens unit of negative refractive power including at least one negative lens element, a second lens unit of positive refractive power including at least four lens elements, and a third lens unit of negative refractive power including at least one negative lens element. The second lens unit is asymmetric with respect to the center of the lens units of the lens system. During zooming, the projection magnification is varied with the conjugate distance being maintained constant by varying the distance between the first and second lens units and the distance between the second and third lens units and by moving the entire lens system. The axial distances among the lens units are defined by predetermined conditions.
