<P>PROBLEM TO BE SOLVED: To provide a mounting adjustment method for a lens barrel, whereby inclination can be accurately adjusted when mounting the lens barrel in a housing. <P>SOLUTION: In three areas on a plane orthogonal to the direction of the optical axis of a photographic lens system, around the rear side of the mounting opening 4d of a housing to which the rear side of the lens barrel is fixed, a cam 10 having a cam face for adjusting the inclination of the lens barrel 3 is provided so as to be rotatable around a rotation shaft along the direction of the optical axis. Provided on the rear side of the lens barrel 3 are cam contact members 11 mounted so as to contact each cam face, and a compression coil spring 14 for energizing each cam contact member 11 in a direction in which it is pressed against the cam face. Each cam 10 is rotated around the rotation shaft and the cam contact member 11 pressed against the cam face is moved forward and backward along the direction of the optical axis, thereby adjusting the inclination required to mount the lens barrel 3 into the housing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
