Abstract
A shutter unit includes a base plate with an aperture, a blade member, a first drive member, a second drive member, and a charge member configured to move the second drive member from a movement completion position to a movement start position against a biasing force on the second drive member, wherein while an image obtained from an image sensor is being displayed in an imaging apparatus during continuous imaging and the first drive member is engaged in order to maintain the retreat state of the blade member, the second drive member is moved to the movement start position by the charge member, and wherein before a display of the image ends, the first drive member moves toward the first direction so that the blade member moves from the retreat state to the closed state.
