Abstract:
To miniaturize an apparatus in association with a charge mechanism.SOLUTION: A blade driving apparatus includes a base plate which has an opening through which light passes, a blade which travels so as to open and close the opening, a driving mechanism which operates the blade, and a charge mechanism which allows the driving mechanism to perform a charge operation. The charge mechanism includes a charge slider which is moved in a direction crossing an optical axis direction by the driving force of a driving source, to operate the driving mechanism. The charge slider includes an input part into which the driving force is inputted and an operation part which operates the driving mechanism. The driving mechanism includes an engagement part which is engaged with the operation part. A force for pressing the charge slider in the direction from the input part toward the operation part is inputted into the input part as the driving force and the operation part is arranged between the input part and the engagement part in the movement direction of the charge slider.SELECTED DRAWING: Figure 30
