<p>PROBLEM TO BE SOLVED: To provide a position adjusting mechanism for an imaging element that can precisely adjust a position and an inclination of an imaging unit to a lens unit even when a distance between a measurement chart and an assembly reference plane is set to be close, and can avoid a squint-eyed state after assembling.SOLUTION: In a position adjusting mechanism, a lens unit holding section has an assembly reference plane orthogonal to an optical axis of a lens unit. The position adjusting mechanism includes a second adjusting section (311-311, 312-312, 314-314, and 313-313) which can adjust an inclination of a chart plane of a measurement chart (1) to the assembly reference plane of the lens unit holding section, and adjust a position of the measurement chart (1) in a direction orthogonal to the optical axis of the lens unit.</p> |
