Abstract:
The image reading apparatus conveys a reading unit or a document to read the document. Conveyance is implemented by motor control based on a target position trajectory. The reading unit reads the document each time a line start signal is inputted. When a predetermined condition is satisfied, the reading operation is invalidated. A conveyance position at a timing to start the first reading operation invalidated is specified as an interrupted position. The object is arranged at a conveyance restart position moved back from the interrupted position. A target position trajectory is newly set. A conveyance time from the conveyance restart position to the interrupted position defined by the target position trajectory is an integral multiple of an output cycle of the line start signal. The motor control based on the target position trajectory is started at a timing coinciding with an output timing of the line start signal.

Abstract:
In an image reading apparatus, a retreat control device moves a conveyance target through a conveyance mechanism, when a stop operation is performed by a stop control device, in an opposite direction to an image reading direction to a position further from a restart reference position set by a position setting unit. A reading control device again moves the conveyance target, which has been moved by the retreat control device, at a constant speed in the image reading direction under a predetermined condition; inputs a line start signal to a reading unit when an offset time set by a time setting unit has elapsed from a time point when the conveyance target reaches the restart reference position; and periodically inputs a line start signal to thereby cause the reading unit to perform a reading operation from a point; where the reading unit is located when the offset time has elapsed.
Abstract:
In an image reading apparatus, a plurality of reading sensors extend in a main scanning direction and separated from each other in the main scanning direction so as to be located in a staggered arrangement in which a part of one of the reading sensors in the longitudinal direction faces a part of adjacent one of the reading sensors in a sub-scanning direction. A first connection member is provided to the part of one of the reading sensors facing the part of the adjacent one of the reading sensors. The first connection member protrudes toward the adjacent one of the reading sensors. A second connection member is provided to the part of the adjacent one of the reading sensors facing the part of the one of the reading sensors. The second connection member protrudes toward the one of the reading sensors. The first and second connection members are brought into contact with each other by being urged by a spring.
Abstract:
A line-imaging lens condenses a light beam from a light-source unit in one direction to form a line image. An optical deflecting unit deflects the light beam passing through the line-imaging lens. An imaging optical unit images the light beam deflected by the optical deflecting unit in a spot shape on a scanning surface to be scanned. An adjusting unit adjusts a position of irradiation of the light beam from the light-source unit on the optical deflecting unit.
Abstract:
Measuring a feed spindle length change in a printing exposer, having at least one exposure head on a carrier moved axially along the drum in a feed direction by a stepping motor and the spindle, carries out the measurement by determining the number of stepping motor cycles needed by the carrier to travel through a reference section parallel to the feed direction. During calibration, an optimum number of cycles per revolution of the exposure drum is set, and the number of cycles needed to travel through the reference section is determined. During an operating phase, the number of cycles needed to travel through the reference section is determined and a corrected number of cycles per revolution of the exposure drum is determined in accordance with the relationship Kk=K0×Mx/M0. The temperature of the components involved in the measurement is kept constant with a temperature control system.

Abstract:
An image reading apparatus includes: a light source; an image capturing device, opposed to the light source through a document table adapted to support a document and operable to receive light emitted from the light source; a detector, operable to detect a light-reception state of the image capturing device when an instruction for reading the document is given; and a corrector, operable to correct a relative position in a sub scanning direction between the light source and the image capturing device based on a detection result of the detector.
Abstract:
An image reading apparatus includes a platen for placing the original, a reading device for reading the original placed on the platen to obtain image data in a first reading mode or a second reading mode; a transport device for transporting the original to be capable of returning the original to the platen; and a detection device for determining whether the image data read by the reading device is a first kind of data or a second kind of data. A control device operates the transport device for ejecting the original and outputting the image data read in the first reading mode when the image data is the first kind, and operates the transport device to return the original to the platen and actuates the reading device to read in the second reading mode when the image data is the second kind.

Abstract:
A method for adjusting a scanning module includes the steps of: providing a first fixing force to mount an adjustment assembly, to which an image sensor is attached, onto a base of the scanning module and loosely fixing the adjustment assembly to the base with a first fixing force; adjusting a relative position between the adjustment assembly and the base of the scanning module, and testing a first adjustment result until the first adjustment result is accepted; securing the adjustment assembly to the base of the scanning module with a second fixing force; and removing the first fixing force. The first and second fixing forces come from different sources.
