Image taking apparatus having a shutter block

摘要

An image taking apparatus is provided with; an optical lens; an image sensor where a subject image formed by the optical lens is taken; and a shutter block situated between the optical lens and the image sensor, and has a shutter blade that is movable between a first position in which the taking luminous flux is intercepted within a plane orthogonal to the optical axis and a second position in which the taking luminous flux is transmitted. The shutter block is held so as to be insertable and detachable within the plane orthogonal to the optical axis.
