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： 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 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.

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： A retinal disease analyzer processes data obtained by processing a color retinal image and measured visual field data provided by a perimeter to detect the condition of the optic disc and defects in the nerve fiber bundles for the clinical analysis of the condition of the optic disc and the defects in the nerve fiber bundles, and combines detected information on a fundus coordinate system taking into consideration the arrangement of the nerve fiber bundles for the comprehensive analysis of the condition and the degree of progress of glaucoma. The detected information is analyzed on the basis of the distribution pattern of the nerve fiber bundles or the corresponding fundus coordinate system to integrate all the data for analysis. The condition and the degree of progress of glaucoma can be determined on the basis of the integrated data.

摘要： An eye characteristic measuring apparatus can effectively and properly measure and display wavefront aberration of an eye regardless of the eye state. A first illumination optical system (200A) illuminates a small area on a retina of the eye by a first light flux from a first light source unit (100). A first reception light optical system (300A) leads a part of light flux reflected from the retina (61) to a first light reception unit (510) via a first conversion member (400) for converting the reflected light flux into at least 17 beams. A measurement data judgment unit, for example, judges whether the measurement data is appropriate for calculating the wavefront aberration according to a first signal from the first light reception unit (510). For example, when the measurement data judgment unit judges that the measurement data is not appropriate, a first correction unit causes to display a check correction screen which will be detailed later and corrects the data into appropriate measurement data. Furthermore, according to the measurement data judged to be appropriate or the measurement data which has been corrected by the first correction unit (603), a calculation unit calculates the wavefront aberration of the eye (60) as optical characteristic. Moreover, a measurement result judgement unit for example, judges whether the wavefront aberration calculated by the calculation unit is appropriate. Moreover, for example, when the measurement result judgment unit judges that the measurement result is not appropriate, a second correction unit (607) causes to display the check correction screen and correct the data into appropriate measurement data.
