ABSTRACT:
A fine position control device for finely adjusting the position of a fixed information carrier such as a transparency in a COM (computer output microfilmer) system. This position control device is capable of moving a fixed information carrier in the X, Y and Z directions in an orthogonal coordinate system and also of rotating the same in the .theta.-direction in the X-Y plane. The position control device has a Y-direction moving stage, an X-direction moving stage which moves in the Y-direction together with the Y-direction moving stage and is movable in X-direction independently of the Y-direction moving stage, a Z-direction moving stage which moves in the X-Y plane together with a member fixed to the X-direction moving stage and is movable in the Z-direction independently of the X-direction moving stage, and a .theta.-direction rotating stage which moves together with the Z-direction moving stage and is rotatable in the X-Y plane independently of the Z-direction moving stage. The .theta.-direction rotating stage is adapted to hold the fixed information carrier. The four stages are respectively connected via feed screws with four control knobs arranged in line.
