PURPOSE:To always maintain a measure accuracy to be high at all times without being affected by eccentricity or the like of a carrier drum. CONSTITUTION:A carrier drum 54 is driven before the scanning by an optical beam and an origin of the carrier drum 54 is found out by a Z phase signal from a rotary encoder 62. Since scanning processing by the optical beam is started by using the origin as a reference position, an image is recorded on the same condition at all times onto each cut film and when the films are overlapped, deviation of each recorded image, that is, a measure error is effectively prevented. |
