Abstract
A blade driving device including, a base plate including an opening through which light passes, a blade configured to runs on a surface of the base plate to open and close the opening, a drive mechanism including a drive spring and actuates the blade; and a charge mechanism configured to perform a charge operation on the drive mechanism against the drive spring. The charge mechanism includes a slide member configured to linearly reciprocate in a direction parallel to the base plate along a motor between the motor and the drive mechanism, the motor generating a driving force for the charge mechanism.

A blade driving device, comprising:
- a base plate including an opening through which light passes;
- a blade configured to run on a surface of the base plate to open and close the opening;
- a drive mechanism including a drive spring and that actuates the blade;
- and
- a charge mechanism configured to perform a charge operation on the drive mechanism against the drive spring,
- wherein the charge mechanism includes a slide member configured to linearly reciprocate in a direction parallel to the base plate along a motor between the motor and the drive mechanism, the motor generating a driving force for the charge mechanism, and
- wherein the drive mechanism, the slide member, and the motor are arranged in a lateral region of the opening from a side of the opening in this order.

- a drive mechanism including a drive spring and that actuates the blade;
- and
- a charge mechanism configured to perform a charge operation on the drive mechanism against the drive spring,
- wherein the charge mechanism includes a slide member configured to linearly reciprocate in a direction parallel to the base plate along a motor between the motor and the drive mechanism, the motor generating a driving force for the charge mechanism,
- wherein the slide member is supported by at least one guide shaft in such a manner that the slide member is capable of reciprocation, the guide shaft being arranged on a surface of the base plate along a side part of the drive mechanism in parallel with a direction of running of the blade, and
- wherein a part of the slide member on one end side of the guide shaft receives the driving force of the motor.
