Abstract
Two microfiches carrying information recorded in different colors which can be detected independently of each other by means of color separation optical system are superposed in the direction of the optical axis of a projection optical system. The two kinds of information recorded in different colors on the two microfiches are separately displayed on a single or two display devices through color separation optical system such as color filters or a dichroic filter. When the two kinds of information are displayed on a single display device, the information is changed over by changing over the color separation system. When the two kinds of information are displayed on two display devices, they are displayed simultaneously.
