PURPOSE:To simplify the positional adjustment of a solid-state image pickup element, by setting the angle between the photoreceptor surface of the solid-state image pickup element and its optical axis under an adjustment-free condition. CONSTITUTION:A stepped section 13 and annular fitting edge section 14 are provided in the vicinity of the end section of an optical bodytube 11 to fit a flange 12 under a rotation-free condition. The flange 12 is fitted to the fitting section 13 of the optical bodytube 11 so that one end face 15 of the flange 12 is fitted to the fitting edge section 14 by means of a screw 16 under a rotation-free condition. When the flange 12 is fitted to the bodytube 11, the outer frame 23 of the supporting member 21 of a solid-state image pickup element 4 fitted to the other end the flange by means of a screw 20, around which a spring 19 is wound, is also fitted to the bodytube 11 under a rotation-free condition around the optical axis. By adjusting the screwing length of the screw 20, the angle between the optical axis and the outer frame 23 of the supporting member 21 can be adjusted optionally. |
