摘要： The use of a blade driving device including a first plate wherein a first opening portion is formed; a blade formed so as to enable opening/closing of the first opening portion; a driving mechanism driving the blade; and a cover, wherein a second opening portion is formed so as to essentially overlap the first opening portion, and formed so as to cover the base plate and the driving mechanism portion. Because the base plate and driving mechanism portion are covered by the cover, when compared to the conventional structure, this enables the transmission, without variability, of heat in relation to the driving mechanism portion and the base plate.

摘要： A focal plane shutter has a base plate with an opening; a leading and trailing blade opening and closing the opening; a leading blade driver; a trailing blade driver; a charging portion; a braking member; and a brake driver. The leading blade driver drives the leading blade through a first biasing force of a first biasing member and drives the leading blade through a second biasing force of a second biasing member. The trailing blade driver drives the trailing blade by a third biasing force of a third biasing member. The charging portion applies the second biasing force to the second biasing member and applies the third biasing force to the third biasing member. The braking member brakes the leading blade through friction and the brake driver moves the braking member to brake the leading blade, independently of the leading blade driver, the trailing blade driver, and the charging portion.
