ABSTRACT:
In order to prevent noise effects from occurring in a detection signal line or in a control signal line, which are small signal lines of a camera, and which are wired close and/or parallel to drive signal lines, which carry a large current, a low impedance line is provided between the drive signal line and the detection signal line and/or the control signal line. The low impedance line can be, for example, a ground line or a power source line. The drive signal line can be, for example, a line that supplies relatively high driving current to a shutter mechanism, to a vibration prevention system (which drives a vibration prevention lens in a direction substantially perpendicular to an optical axis of the lens system), and/or to an auto focus system (which drives a focus lens in a direction substantially parallel to the lens system optical axis). The detection signal lines and the control signal lines can carry detection or control signals for the vibration prevention system or the auto focus system, for example.
