摘要：A color image reproduction apparatus includes a light source, a filter, a sensormeans, an ink ribbon, a printer including a printer head and a printer drive, a feeder and acontroller. The light source illuminates spots on the color original and light reflectedtherefrom is filtered by one of three aligned segments of the filter which are connectedend-to- end in an alignment direction which three segments respectively filter differentfirst, second and third portions of the visual spectrum. The sensor is disposed behind thefilter and senses the light filtered by one of the three different filter segments when theone of the segments is disposed in front of sensor. The sensor outputs an intensity signalindicating the intensity of the sensed light. The ink ribbon is fixed in relation to the filterand has three different color ink layers which are attached to each other end-to-end inthe same alignment direction as are the light filter segments. Each ink layer is spaced apredetermined distance from a corresponding one of the three different filter segments.The printer head is disposed behind the ink ribbon and is spaced from the sensor adistance equal to the distance between corresponding ink layers and filter segments so

as to be operable to apply ink from the ink layers to a print surface. The feeder

successively feeds the three different filter segments across the front side of the sensor,and simultaneously successively feeds the three different ink layers across the front sideof the printer head.
