ABSTRACT:
A void space or region is formed within a camera body to protectively enclose a circuit board which controls the operation of the camera. Openings are formed to allow electric circuits and parts located outside of the region to be electrically connected to the circuit board. The openings are sealed with connecting terminals or seal members to tightly close or seal the region. Water, dust and the like are thereby prevented from entering the camera body from outside, and corrosion of essential electrical parts thus is avoided.
