PURPOSE:To interlock a zooming and to improve the accuracy of a right and left image ratio at the time of interlocking by disposing an adjusting mechanism in a stopper for regulating the wide angle end or the telescope of a zoom mechanism. CONSTITUTION:A zoom lens 1 moves from a telescopic side to a wide angle side with a range 5 in a cam cylinder 2 and the stopper 4 moves from an A point to a B point in a slide groove 3 accordingly thereto. The stopper 4 is constituted of an adjusting screw 4a and an adjusting plate 4b on which an oblong hole 4c is bored to move the adjusting plate 4b in the range of the oblong hole 4c by loosening the adjusting screw 4a. Herein, a position at which the stopper 4 butts against the B point of the wide angle side is adjusted to make the size of the images of the wide angle side of the right and left cameras equal. Thereby, a right and left interlocking zoom can be controlled with a high accuracy to attain a powerful stereoscopic photographing by using the interlocking zooming. An adjusting operation performed by a user is reduced according to an automatic tracking by the microcomputer control of the right and left zoom to improve an operability. |
