发明名称 FOCUSING DEVICE FOR IMAGE RECORDING SYSTEM
摘要 PROBLEM TO BE SOLVED: To provide an image exposure system capable of easily, accurately, inexpensively and automatically fetching a focused image by using a fixed lens system because a distance from a lens to an exposure surface is fixed in an inexpensive camera manufactured by using a fixed lens system. SOLUTION: This image recording system is provided with plural light beam sources. By moving a camera to a position where the respective light beams projected to an object are superposed or crossed, a situation that the object exists at a position at an exact distance from the image recording system is confirmed. Thereafter, the focused image is projected to an image recording medium.
