APPARATUS FOR DETECTING POSITION OF IMAGE PICKUP ELEMENT

摘要

An image pickup element position detection device (10B) of the present invention detects a positional relationship between an image pickup element (2) and a lens (3) which are to be mounted on an optical system device and face each other. The image pickup element position detection device (10B) includes (i) an opposing mirror (5) which is disposed parallel to the image pickup element (2) so that the opposing mirror (5) and the image pickup element (2) are placed on opposite sides of the lens (3) and (ii) at least two side mirrors (11a and 11b) which face each other are disposed (i) perpendicularly to the opposing mirror (5) and (ii) on respective lateral sides of an area between the opposing mirror (5) and the lens (3).
