Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an exposure device for a photographic recording material having sufficient light intensity for exposure and easily driven. SOLUTION: A digital image producing device is provided with an exposure means, an optical modulator, a control means and an objective lens inside. The exposure means is provided with many LEDs 12a,..., 20n as a light source and adjusting means 10, 11a,..., 11n adjusting light emitted from the LEDs. The LEDs are connected to each other by combining at least one serial circuit with at least one parallel circuit. The light intensity necessary to expose a photographic recording material is obtained by many LEDs, consequently, a short exposure time is realized. By connecting the LEDs in the above method, a voltage and a current for driving this device are prevented from reaching a large value requiring technical labor and time, and the device is easily driven. Further, the light intensity is locally controlled by the adjusting means and the quality of the exposure is improved.
