の感度)。[Scope of Claim for Utility Model Registration] A traveling exposure type photosensitive material exposure apparatus in which one of the exposure light source and the photosensitive material is moved relative to the other one or more times to expose the photosensitive material. The applied exposure control device includes: an illuminance measuring unit that measures the illuminance of an exposure light source; and a number of traveling exposures so that the actual total exposure becomes the target total exposure based on the illuminance measured by the illuminance measuring unit. and a calculation unit that automatically determines the running speed by calculation, and a control unit that controls the drive mechanism of the exposure apparatus based on the number of travel exposures and the travel speed determined by the calculation unit, the calculation unit is the following formula based on three elements: illuminance of the exposure light source, running speed, and number of running exposures.
By calculation according to the following formula (2) that includes the exposure count defined in (1) as an exposure control variable, the value of the number of traveling exposures Kw is determined so that the desired traveling speed Sw is within the allowable range of the drive mechanism. 1. An exposure control device for a traveling exposure method, characterized in that the traveling speed and the number of traveling exposures are determined by changing the traveling speed. Equation (1) Exposure count = illuminance of exposure light source x (1/running speed) x number of driving exposures Equation (2) Sw = EEw・Kw x SK x (La/Lb) However, in equation (2), La is , the illuminance of the exposure light source under specific conditions that actually yield the appropriate total exposure amount, Lb is the illuminance of the exposure light source measured prior to the exposure operation, K is the number of exposures under the specific conditions, and Kw is the calculated The number of traveling exposures, S is the traveling speed under the specific conditions, Sw is the desired traveling speed, E is the reference exposure count determined based on the above formula (1) under the specific conditions, and Ew is the following formula ( Represents the exposure count for exposure work defined in 3). Equation (3) Ew/E=(sensitivity of photosensitive material actually used in exposure work)/(sensitivity of photosensitive material under the above specific conditions).
