Abstract

PURPOSE:To scan the entire surface of a negative by color separation by a simple structure wherein a rotary disk having fitted filters, slit masks of various sizes, line sensor photodetectors, etc., corresponding to them are incorporated. CONSTITUTION:Light from a light source for lighting consisting of a lamp 8 and optical fibers 7 passes through one of filters 11 fitted to a rotary disk 10 rotated by a motor 9 to light up the screen 2 of a negative 1, and further passes through a scanning slit mask 3 to form a slit-shaped negative image 6 on an array of line sensor photodetectors 5 through a lens 4. The outputs of the line sensor photodetectors 5 are sampled every time the light passed through each filter 11 reaches the slit mask 3, and led out successively by a multiplexer, thus scanning the neagtive 1 at right angles to its advancing direction.
