PURPOSE: A camera having a zoom lens barrel driving system is provided to control zoom operation and focal point with a single driving source and to provide a compact and inexpensive product by having a structure for realizing a multi-stage focus control. CONSTITUTION: A camera having a zoom lens barrel driving system includes a single zoom driving source, a helicoide ring(29) rotating by the zoom driving source, a focus lever assembly interlocking with the rotation of the helicoid ring, a relay lever(107) receiving driving power of the zoom driving source from the focus lever assembly and rotating, and a front lens group varying a position of an optical axis direction by the rotation of the relay lever and performing focusing. The focus lever assembly has a focus lever having surfaces having different diameters in a rotational center. The focus lever is disposed at an output shaft of the focus lever assembly for changing a rotating angle of the relay lever. |
