ABSTRACT:
A camera has a camera body being made of an electro-conductive material and a plurality of windows for light-projection or a light intake thereon. At least one of covering members for the windows includes an exposed part being exposed toward an outside of the camera and a hidden part being located in an inside of the camera. A first electrode is attached to the exposed part and a second electrode is attached to the hidden part. When a finger obstructs the window, a detecting means detects a finger obstruction by comparing the electrostatic capacity at the first electrode with that at the second electrode relatively. Then, warning is generated for indicating the finger obstruction by a warning generating means.
