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: An image forming method is performed by an image forming apparatus having a head mounting a plurality of writing units that form an image on a recording medium. The writing units are aligned in a sub-scanning direction perpendicular to a main-scanning direction. A part of the image is formed on the recording medium by the writing units, the part of the image forming a line extending in the main-scanning direction. The step of forming a part of the image is repeated while shifting the writing units in the sub-scanning direction by a predetermined amount of shift. The amount of shift of the wiring units is varied so that an amount of misalignment in a connecting portion between the parts of the image on the recording medium is reduced.

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 recording apparatus records an image on a printing plate wound around a rotating drum with a light beam emitted from an exposure head. In the image recording apparatus, an actual drum rotational speed Nx is recognized, and the image is recorded on the printing plate in an accelerating period in which the actual drum rotational speed Nx is equal to or higher than a predetermined rotational speed, a constant-rotational-speed period, and a decelerating period. An exposure beam position, an exposure beam output, and an auxiliary scanning speed of the exposure head are corrected dependent on the peripheral speed of the drum in the accelerating period and the decelerating period.

Abstract: An image scanner allows the reflection from the image on the face containing the image data to read of an original to strike on a one-dimensional image sensor and thus scans and reads the entire image on the original's face. The image scanner includes brightness sensing means for sensing ambient brightness and means for varying the reading speed of the one-dimensional image sensor in accordance with the brightness sensed by the brightness sensing means. In light surroundings, the scanner generates relatively fast clock signals, making the original's face scanning faster according to these clock signals, producing image data signals without saturating their output capacity. In dark surroundings, the scanner generates relatively slow clock signals, making the original's face scanning slower according to these signals, producing image data signals with a satisfactory S/N ratio.

Abstract: An electronic device includes a carriage on which an image sensor is mounted, a motor that drives the carriage, and servo-control-containing printed matter provided in one or more detection areas of the image sensor or one or more independently provided optical sensors. The servo control information is used for speed control and initial position detection of the carriage. A servo controller performs the servo control on the motor via a motor driver based on the read servo control information. The printed matter is provided on a rear or underside surface of a support structure in areas irradiated by a light source for the image sensor. Printed matter for speed control may be provided in one area and printed matter for initial position detection in another.

Abstract: An error detection apparatus and method for use with engravers, such as gravure engravers. An error value E corresponding to the difference between a set of predetermined setup parameters and actual measurement of a portion of an engraved area on the cylinder is determined. The error value E is then used to adjust the engraver to engrave an actual cut or etch in accordance with the set of predetermined setup parameters. Advantageously, an error detection and correction system is suitable for providing a closed-loop system for engraving a cylinder. The apparatus and method may be used during initial setup or during normal operation of the engraver. Other features include an autofocus routine to facilitate the auto-focus procedure. Also, image processing is further enhanced by gap filling, discontinuity removal, and light calibration methods which may be used alone, in combination with each other, or in combination with the automatic focus system and/or automatic shoe system.
