FOCAL PLANE SHUTTER AND CAMERA
Document Type and Number:
Japanese Patent JP2015143744
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve simplification of a structure, aggregation of a component and the like in focal plane shutters.SOLUTION: A focal plane shutter comprises: a base plate 10 that includes an aperture 10a; blade members 20 and 30 that open/close the aperture; main drive members 41 and 51 that are urged in a direction allowing the blade members to perform a shutter action; a setting member 60 that allows the main drive members to be set at a set position prior to the shutter action against urging force; slave drive members 42 and 52 that are urged so as to follow the main drive members coupled to the blade members and set at the set position, and move by being pushed with the main drive members upon performing the shutter action; and a regulation mechanism 70 that regulates a movement of the slave drive member 52 in order to keep the blade members in a closed state. The regulation mechanism 70 includes a regulation member 71 that is engaged with the slave drive member 52 to be urged so as to regulate the movement of the slave drive member, and moves so that an engagement of the main drive member 51 causes the regulation of the movement of the slave drive member to be released before the setting member completes a setting action. Accordingly, simplification of a structure, aggregation of components and the like can be attained.
