FOCUS ADJUSTING DEVICE FOR ZOOM CAMERA

摘要

The cam plate(45) into which the projections(24)(26) of operating levers(21)(22) are inserted and led, is installed in main body and cam holes(46)(47) are also made a bit far from the main body, and the cam holes(46)(47) possess some inclines(48)(49) to change standard and long range focuses. The projections(24)(26) of operating levers(21)(22) are attached to one part of cam holes(46)(47) by tension power of tension springs(33)(34), the projections(25)(26) are led along the sloping side(48)(49) of the cam holes(46)(47) by focus control of lens barrel(1) moving front and back by motor(3), and the operating levers(21)(22) rotate at a certain angle. Therefore, the rotating levers(43)(44) geared with operating levers(21)(22) are linked together to change the focus of optical axis.
