Patent ID: 8633993

Claim:
A flexible wiring board mounting structure of an image shake correcting apparatus, said image shake correcting apparatus including an image sensor serving as a part of a photographing optical system and capable of moving in directions orthogonal to an optical axis of said photographing optical system, a control circuit mounted to an element independent of said image sensor, and a flexible wiring board which connects said image sensor and said control circuit to each other, wherein said photographing optical system includes a plurality of lens groups, each of which is supported by a ring member, and wherein said flexible wiring board comprises: an inner side connecting portion connected to said image sensor; an outer side connecting portion connected to said control circuit; and a flexible portion provided in an allowance space, wherein said allowance space is defined between said inner side connecting portion, said outer side connecting portion, said image sensor and a cylindrical inner peripheral surface of an innermost ring member, out of said ring members that support said plurality of lens groups of said photographing optical system, the flexible portion comprising: a first jutting portion which that is flexible and is bent at an end of said inner side connecting portion to extend forward in said optical axis direction within said allowance space, a second jutting portion which that is flexible and is folded back to extend rearward in said optical axis direction at a position radially outward from a position of said first jutting portion, a rear end of said second jutting portion being bent in a direction away from said optical axis to be continuous with said outer side connecting portion, and a flexible connecting portion connecting said first jutting portion to said second jutting portion, thereby defining said flexible portion.
