Abstract

A focal plane shutter includes: a board including an opening; a leading blade and a trailing blade opening and closing the opening; a trailing blade actuator driving the trailing blade; a drive member driving the trailing blade by receiving driving force of the trailing blade actuator; and a buffering member abutting with the drive member in a state where the trailing blade recedes away from the opening, wherein the trailing blade actuator causes the drive member to move away from the buffering member from an abutting state therewith and to abut therewith again in a charging operation, and then starts an exposure operation.
