<P>PROBLEM TO BE SOLVED: To provide a laser exposure apparatus which can inexpensively decrease misregistration of dots in scanning exposure even when temperature changes in an optical system. <P>SOLUTION: A photographic print apparatus 1 includes an optical system 33, an optical system temperature sensor 50, and a quartz oscillator 69. The optical system 33 is laid on the optical path for scanning exposure by a laser beam LB according to the frequency of a reference clock. The optical system temperature sensor 50 detects a temperature in the optical system 33. The quartz oscillator 69 generates a reference clock of a frequency modulated according to the temperature detected by the optical system temperature sensor 50. <P>COPYRIGHT: (C)2007,JPO&INPIT |
