Summary:PURPOSE:To facilitate the replacement of original image by driving and indicating the indication pattern of a transmission type liquid crystal display equipment by a control signal from outside. CONSTITUTION:Laser light 2 generated from a laser oscillator 1 is magnified by a concave lens 3, made parallel by a collimate lens 4, and projected on a transmission type liquid crystal display equipment 10. The laser light transmitted through the equipment 10 is converged and projected on the surface of a sample 7 through a projection lens 6. The lens 6 is so arranged that the image of the equipment 10 is subjected to contraction projection on the surface of a sample 7, and a reduced image of the equipment 10 is printed on the sample surface. A signal control unit 11 makes a storage device store an image signal obtained from a pickup tube 12, reads out the signal from the storage at the time of display mode, makes the equipment 10 indicate it, and controls the oscillator 1.
