In Japanese Patent No. 6190, a band-shaped substrate is bent into a substantially polygonal shape in order to accommodate it along a wall surface in a cylindrical or polygonal cylindrical housing, and electric parts are mounted on a flat surface portion between the bent portions. There is disclosed a flexible printed circuit board configured so as to be housed in the housing so as to be substantially parallel to the axial direction of the housing.

リント基板を提案している。Further, in the Japanese Patent Application No. 5-54355, the applicant of the present application discloses, as a flexible printed circuit board to be housed in a lens barrel, an annular portion having an opening at the center through which a photographing light beam passes, and the circle. A protrusion for mounting an electrical component that protrudes outward or inward from the ring-shaped portion, and bends the protrusion so that it is substantially parallel to the optical axis of the lens barrel and stores it in the lens barrel. We propose a flexible printed circuit board with such a structure.

らない問題点がある。In the flexible printed circuit board having the above-mentioned structure, many parts are mounted close to each other on the same plane in order to mount a large part on the board or to suppress the influence of noise. When it is desired to make it possible, it is necessary to make the plane part for mounting the electric component as large as possible. However, in the configuration in which the conventional substrate is simply bent into a polygonal tubular shape, the outer diameter when the substrate is housed becomes large by enlarging the flat portion, and the diameter of the lens barrel to be housed must be large. There are problems that must be addressed.

題点が生じる。In particular, in the flexible printed circuit board, stress is applied near the bent portion at the end of the flat surface, so that it is necessary to provide a bending margin, and it is not possible to mount components up to the end. In the case of mounting or high-density mounting, a flat surface portion having a larger area is required, which causes a problem that the outer diameter at the time of housing the substrate becomes large and the lens barrel to be housed becomes large in diameter. .

An object of the present invention is to provide a flexible printed circuit board that can be suppressed.

きる。In the structure of the second embodiment, the annular substrate is bent at about 90 ° at the bent portion between the flat portion and the connecting portion to form a polygonal tubular shape, and the bent portion Since the bending angle is small, there is no possibility that the board or the wiring pattern is cut at the bent portion. Further, since the flat portion on which the components are mounted is arranged directly on the outer peripheral surface of the pedestal in the housed state, the thickness is smaller by the amount of the connecting portion as compared with the configuration of the first embodiment, and the flexible printed circuit board when housed And the diameter of the lens barrel can be made smaller.
Also, since the flexible printed circuit board has a ring-shaped configuration, the wiring between the flat parts on which the components are mounted can be shortened, the wiring design can be facilitated, and the effects of noise, etc. can be reduced. Can be reduced.
