Abstract
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.
