摘要： An image recording device, wherein deviation of an image-recording start position, which results from a difference in the amount of expansion and contraction based on temperature changes between a printing plate precursor, a rotating support, a mechanism for moving a recording head, and the like, is corrected so that an image can be recorded at a proper position. Temperature 1 near the rotating support is obtained by a first temperature sensor, and temperature 2 near the mechanism is obtained by a second temperature sensor. Then, an amount for correcting an image-recording start position is obtained from a correction table based on the temperatures 1 and 2 and on a size of the printing plate precursor, and the number of drive pulses for correction corresponding to the obtained amount of correction is outputted to a drive motor of the mechanism.

摘要： A laser exposure device at which alignment marks of a plate material on an exposure stage, which is moving in a direction opposite to a scanning direction, are read by a CCD camera mounted at a support gate, after which an imaging region, whose position is judged using the alignment marks, is exposed by a laser beam from a laser scanner. Here, a distance along the scanning direction from the CCD camera to the laser scanner is not less than a pitch of the alignment marks that are provided to respectively correspond to a trailing end and a leading end of the imaging region. According to this laser exposure device, even in a case in which a plurality of the imaging region is provided at a recording medium, an increase in a duration for forming images on the recording medium in accordance with an increase in imaging regions is prevented.

摘要： For dividing an image and recording divided images on a photosensitive film with a plurality of laser beams, an auxiliary scanning speed is reduced in the vicinity of junctions between adjacent ones of the divided images to adjust the intervals between main scanning lines, and each of the main scanning lines is divided into divided main scanning lines in a main scanning direction, and the divided main scanning lines are formed separately in an auxiliary scanning direction. With such a correcting process, a high-quality image free of striped artifacts and inclination differences of main scanning lines can be recorded on the photosensitive film.

摘要： The drum has a balancer disposed at both ends of a drum body around which a printing plate is wound, and with a rotating shaft rotatably supported by a supporting plate via an elastic support member of a shaft receiving member. When the rotating drum is rotated in a state in which the rotating drum is out of balance, the elastic support member is elastically deformed so that the rotating shaft rotates integrally with the rotating drum. Balance of the drum is restored by eccentric revolution of the balancers, whereby the rotating drum is rotated around a center of the rotating shaft. A recording head is mounted at a bracket that moves integrally with the rotating drum. Thus, the recording head continually opposes a fixed position at the rotating drum, and an appropriate image can be formed on a printing plate.
