摘要： An original size sensing method for an apparatus which includes a photoelectric converter for reading an image of an original placed on a platen, and a light source for irradiating the original with light, determines the presence/absence of incidence of ambient light on the basis of an output from the photoelectric converter while the light source is kept off. When ambient light is found to be incident, the method determines the size of an original placed on the platen on the basis of that output from the photoelectric converter, which falls outside the range in which the ambient light is incident, while the light source is kept on.

摘要： Disclosed is an image reading apparatus for moving a document reading unit to a point below a document feeder that feeds documents, and emitting light from a light source of the document reading unit toward a feed roller of the document feeder, whereby light reflected from a document that travels between the feed roller and the light source is sensed by the document feeding unit to thereby read an image on the document. The apparatus includes a photoelectronic converter for outputting an electric signal that conforms to amount of incident light, and a reading position setting unit for moving the document reading unit, irradiating the feed roller with light from the light source at each position to which the document reading unit is moved, causing the photoelectronic converter to output an electric signal that conforms to amount of light reflected from the feed roller at each position, detecting a range in a sub-scan direction over which this electric signal exceeds a predetermined threshold value, and setting a position at the center of this range as a reading position.

摘要： It is an object to identify a failed portion in a circuit for image processing and notify a service center of the failed portion, thereby enabling the failed circuit to be promptly replaced. Circuit portions of image processing units are constructed on separate substrates. As processing routes of an image signal which is inputted from an A/D converting unit, a route in which the image signal passes through a given circuit portion and a route in which the image signal doesn't pass therethrough are set. Data of a predetermined pattern is processed by those processing routes. The presence or absence of a failure of each circuit portion is discriminated from the processing results. The discrimination result is transmitted to an external apparatus installed in a service center.

摘要： The objective of this invention is to provide an apparatus which can form a high-quality image by reliably adjusting the superposing positions of frame images when a single image is formed by superposing a plurality of frame images, and especially, the objective of this invention is to reliably adjust the superposing positions of frame images and form a high-quality image by controlling a rotary polygon and image carrier to operate in association with each other. To achieve such objectives, the apparatus of this invention generates a first signal indicating that the light beam coming from the rotary polygon has scanned a predetermined position, also generates a second signal independently of that detection, and moves the image carrier by selectively using the first and second signals as needed. In this apparatus, by rotating a driving means N times on the basis of a reference signal obtained by frequency-dividing the first signal, the image carrier completes one rotation. During this interval, M first signals are generated. When X signals indicating the rotation timings upon one rotation of the driving means are generated, the frequency division ratio is given by n=N×X/M.

摘要： An image forming apparatus in which two delay time generators input data for two delay times, and a reference signal, and outputs two pulse signals having predetermined pulse-widths. A pulse generator generates a pulse signal based on the phase difference between the two output pulse signals. The pulse-width and pulse position of the generated pulse signal is arbitrarily controlled by the two output pulse signals.
