  • Patent number: 8014082
    Abstract: One end of an FPC (21) for supplying power to the driving section of a light amount control section provided in a shutter unit (20) is disposed between a second lens holder (17) and the shutter unit (20) secured to this second lens holder (17) and is held between the second lens holder (17) and the shutter unit (20). Thus, the FPC (21) is prevented from being spaced apart from the shutter unit (20), and a member for securing the FPC (21) to the shutter unit (20) is eliminated, reducing the number of part items. Further, the second lens holder (17) and the shutter unit (20) blocks unwanted light toward the FPC (21), so that a ghost image is prevented from appearing on an image due to unwanted light reflected on the FPC (21).
