摘要： A shutter unit includes a base plate having an opening, a first blade member movable between a closed state and a retracted state, a first driving member biased by a first biasing member, a second driving member biased by a second biasing member, a first charging member configured to cause the first driving member to move in the second direction against a biasing force, a second charging member configured to cause the second driving member to move in the first direction against a biasing force, and a motor configured to supply a driving force to the first and second charging members. In a case where the first charging member causes the first driving member to move, the motor rotates in a direction opposite to a rotation direction in a case where the second charging member causes the second driving member to move.

摘要： A shutter apparatus includes a shutter base plate having an aperture, a blade group configured to open and close the aperture, a blade driving member configured to drive the blade group, a charge lever configured to rotate the blade driving member, a first roller which is attached to a first axis portion extending from the blade driving member and abuts against the charge lever, a cam member configured to rotate the charge lever, and a second roller which is attached to a second axis portion extending from the charge lever and is configured to trace a cam portion formed on the cam member. The cam member has a flange protruding from the cam portion to periphery of the cam member. And the cam member is arranged so that the second roller is overlapped with the flange in an extending direction of the second axis portion.
