摘要： A reading device including a reader, a position reference member, and circuitry. The position reference member has a reference pattern along a first direction of the position reference member. The circuitry is configured to detect the reference pattern of the position reference member; determine coordinates of at least two pixels in the second direction, based on the detected reference pattern; calculate a first correction value based on the coordinates determined for the at least two pixels of the reader in the second direction; detect an outer shape and a position of an image pattern on the conveyed object based on data read by the reader; obtain a difference between an image of the conveyed object, of which a shape has been corrected, and an image of the conveyed object, of which a shape has not been correction; and set a second correction value based on the obtained difference.

摘要： A conveyance apparatus includes a plurality of conveyors and an image reader. The plurality of conveyors conveys a recording material. The image reader reads a pattern image on the recording material being conveyed. The conveyance apparatus further includes circuitry to control the image reader. The circuitry controls the image reader to read the pattern image on the recording material in a period including a timing at which a trailing edge of the recording material being conveyed by at least two of the plurality of conveyors exits an upstream conveyor among the at least two of the plurality of conveyors in a direction of conveyance of the recording material.

摘要： An image reading device includes a background member, an illumination unit opposed to the background member, and a reader. The illumination unit emits light to a recording medium having an image thereon. The reader receives a reflection from the recording medium to read the image. The background member has a facing surface that faces the recording medium. The facing surface includes a reference portion on a center portion in a width direction of the background member. The reference portion has a higher reflectance than an end portion of the facing surface in the width direction.

摘要： An image reading device includes a plurality of image reading units arranged at different positions in a width direction perpendicular to a conveyance direction of a recording medium to read an image on the recording medium at image reading positions and a conveyance roller pair that conveys the recording medium to the plurality of image reading units. The conveyance roller pair includes a drive roller and a driven roller that contacts the drive roller and rotates following the drive roller. The plurality of image reading units includes an upstream and a downstream image reading units downstream from the upstream image reading unit in the conveyance direction. A reading interval between the image reading positions and a diameter of the drive roller satisfy the relation: X2=n1×π×D1a, where X2 represents the reading interval, n1 represents an integer, and D1a represents the diameter of the drive roller.

摘要： A conveyance device includes a conveyance roller pair to convey a recording medium to an image reading position of an image reading unit. The conveyance roller pair includes a drive roller and a driven roller. The driven roller contacts the drive roller and rotates following the drive roller. The drive roller has a diameter satisfying a relation in which a detection mark on the recording medium is on a position away from a leading end of the recording medium by an integral multiple of a circumference of the drive roller in a conveyance direction of the recording medium.

摘要： A conveyance control device includes a fixing device including a first rotary body, a cooling device including a second rotary body, and control circuitry. The circuitry records a first drive amount for the second body when the first and second bodies are driven at a speed, a second drive amount for the second body when the second body is driven without the first body being driven, a third drive amount for the second body when the second body is driven to rotate faster than a rotating speed and the first body is driven, and a fourth drive amount for the second body when the second body is driven to rotate slower than the rotating speed and the first body is driven. The circuitry performs correction based on the drive amounts in such a manner that a drive amount of the second body becomes equivalent to the second drive amount.
