Abstract

PURPOSE: To readily and easily perform focusing by rotating the camera lens-barrel through operation of its operating cord.
CONSTITUTION: An operating force transmission mechanism 8 and a lens-barrel operating member 11 of sector form are disposed on the device body 1 of box type in which a pair of right and left rollers 3, an operating cord take-up pulley 5, gear 4 and synchronous rotator 6 are housed, whereby these are driven and connected. Also a camera mounting member 2 is disposed thereon. If with this arrangement the camera is fixed onto the device body 1 by way of the camera mounting member 2, the lens-barrel A' makes contact with the friction contact member 11' of the lens- barrel operating member 11. When an operating cord 7 is pulled out by setting the finger to the finger set member 20, the gear 4 rotates, causing the lens-barrel operating member 11 to rotate about a fulcrum 12 by way of the gears 8aW8d, cam member 9 and cam follower member 10. The lens-barrel A' is thereby rotated and desired focusing accomplished.
