Document Type and Number:
Japanese Patent JP5637900
Kind Code:
B2
Abstract:
A second blade-driving mechanism includes second blade-driving first member and second blade-driving second member, only the second blade-driving second member is rotated against elastic force of a blade-driving spring while the second blade-driving first member engages and is locked by a locking member at start of cocking operation of the cocking member to keep a second blade covering an exposure aperture, and the second blade-driving first member is disengaged from locking member at final stage of cocking operation, so the second blade-driving first member can be rotated by elastic force of a second blade-cocking spring and the second blade is made to open the exposure aperture. Staring cocking operation of a focal plane shutter is possible irrespective of the length of time during which imaging information can be transferred from an image sensor to storage via an information-processing circuit.
