摘要： This invention provides a three-dimensional measurement system that improves the efficiency of and enables the automation of non-contact three-dimensional measurement over a wide range using a coded target. A measuring object 1 is photographed in stereo such that the resulting images include four coded marks CT each having a position detection pattern P1 and a code pattern P3. A series of images are photographed in stereo such that adjacent images share two coded marks CT. The position detection pattern P1 and the code pattern P3 are extracted from a pair of photographed images. A point corresponding to a reference point is searched for using the identification codes of the coded marks CT. A stereo matching area is determined. All the processes including photographing, extraction, orientation and three-dimensional measurement can be fully automated.

摘要： An image photographing device for three-dimensional measurement sequentially photographs a measuring object in an overlapping manner by a single camera. The image photographing device for three-dimensional measurement photographs the measuring object with marks having self-other identifiable identification codes, extracts the marks from a photographed image, identifies the identification codes of the marks, defines an area of the measuring object in the photographed image into photographed areas surrounded by the marks, counts a number of photographing times of each of the photographed areas which are involved in different photographed images, groups the photographed areas in response to the number of photographing times, inputs positions of the marks in a coordinate space of a photographing range image of the measuring object, connects the positions of the marks input in the photographing range image such that mark symbols of the marks surrounding the photographed areas correspond to each other to match the photographed areas into the photographing range image, and indicates the photographed areas matched into the photographing range image.

摘要： An image forming apparatus is provided in which, during a continuous sheet passing, in the case where a between-sheets time is short, none of a cleaning mode and a drive OFF mode is performed; in the case where the between-sheets time is of a medium length of time, the cleaning mode is performed but the drive OFF mode is not performed; and in the case where the between-sheets time is long, both the cleaning mode and the drive OFF mode are performed. As a result, degradation of an image bearer due to the cleaning bias is alleviated, decreased productivity due to the cleaning mode is alleviated, a problem is alleviated in which a back surface of a recording medium gets dirty due to toner adhered to a transfer rotation body, and another problem is alleviated in which the service life of a driven member is shortened.

摘要： A sheet feeding device includes a support, a rotation driver, a guide, a support shaft, a biasing member, a leading end sensor, a roller, an outer diameter sensor, and circuitry. The circuitry causes the rotation driver to rotate a spool in a winding direction to determine a timing at which a signal change rate exceeds a change rate threshold as a passing time at which a leading end of a continuous sheet passes through the leading end sensor, causes the rotation driver to rotate the spool by a rotation angle in the winding direction, from the passing time, to position the leading end of the continuous sheet at a feeding start position, and rotates the spool in a feeding direction to feed the continuous sheet from the feeding start position along a guide portion. Further, the circuitry changes the change rate threshold based on an outer diameter of a roll.

摘要： A control device for an image forming apparatus that transitions to a restricted mode which is a print mode to alternately transition between a printable state to perform a print operation, in which a predetermined print amount is printable, and a sleep state to stop a subsequent print operation for a predetermined sleep time after the print operation is performed, includes a print-operation determiner and a print controller. The print-operation determiner determines, when a print-operation execution request to the image forming apparatus is received in the sleep state, whether the image forming apparatus is to perform the subsequent print operation based on a print amount of the print-operation execution request. The print controller controls the subsequent print operation of the image forming apparatus according to a determination result of the print-operation determiner as to whether the image forming apparatus is to perform the subsequent print operation.
