Abstract

A shutter apparatus includes a blade member, a blade moving member, a locking member, a cam member, and a restriction member. The cam member moves the locking member from the locking position to the non-locking position so that the blade moving member moves from the closing position to the opening position. The restriction member moves from the non-restriction position to the restriction position after the blade moving member moves from the closing position to the opening position. The cam member moves the locking member in a direction opposite to a direction from the non-locking position to the locking position so that the locking member moves the restriction member from the restriction position to the non-restriction position.
