HARD PACKING ASSEMBLY OF ZOOM CAMERA

摘要

PURPOSE: A hard packing assembly of a zoom camera is provided to prevent abnormal zoom operation due to overload of a cam at a changed curve point of a cam curve and to reduce error in zoom operation generated by processing error and assembling error. CONSTITUTION: A hard packing assembly of the zoom camera includes a zoom ring(15), a rear lens group frame(17) and a cam unit. The zoom ring has a front lens group(200) and moves back and forth along a light axis. The rear lens group frame has a rear lens group(300) located on the same light axis as the front lens group and is connected to the zoom ring. The cam unit compensates an optical position of the rear lens group to the front lens group during a zoom operation.
