Abstract

PURPOSE: To obtain the optical system device which permits viewing in multiple directions through simple operation by forming the end portion of the lens-barrel as a swing barrel.
CONSTITUTION: The end portion of a lens-barrel 3 is constituted as a swing barrel 2 built in with a fish-eye lens 1 and first relay lens 4 and is made turnable with a rivet 13 as a fulcrum. A reflecting mirror 15 and second relay lens 5 are provided oscillatably and movably in the lens-barrel 3 and are interlocked to the swing barrel 2. Then, when a handle lever 24 is turned to the right or left, the swing barrel 2 is rotated to the right or left by means of a sprocket gear 24, chain 23, sprocket gear 20, pulley 21 and fixing pin 26. At the same time the reflecting mirror 15 is oscillated by means of an arm 7, push rod 8, connecting rod 9 and lead arm 6 and the second relay lens 5 is moved in the optical axis direction by means of a wire 22 and moving lens frame knob 16, whereby the viewing in the multiple directions is readily made possible.
