Abstract
PURPOSE:To exercise stable and easy control over the focus and magnification ratio independently of other controls, by sliding the block containing an optical lens to project a picture, a CCD element to receive the projection and other along a guide axle which is parallel to the optical axis. CONSTITUTION:The printed circuit boards 4a and 4b to which the lenses 2a and 2b plus the CCD elements 3a and 3b are adhered are bound to the lens supporting blocks 1a and 1b via various kinds of control mechanisms. The rail (guide axle) 6 is bound to the base 5 in parallel to the light axis. The block 1a is pressed to the rail 6 by the pressure plate 7a1 and 7a2 provided to the base 5 and then put on the base 5. At the same time, the block 1a is supported by the coil spring 8a and the control screw 10a which fits the stand 9a bound to the base 5. The position of the block 1a is controlled in the direction of the optical axis by the screw 10a. Thus the control over focus and magnification ratio can be exercised independently of other controls. The block 1b is also controlled in the same way as the block 1a.
