In order to grasp an image capturing range, an image monitor is used for recognizing the range. A camera device of the present invention has a configuration that, depending on the shape and position of a shield unit that limits a range where a display lamp is visible, the range where the display lamp is visible is limited, and by making the range where the display lamp is visible and the angle of view of the camera coincident with each other, a subject can recognize to be within the image capturing angle of view during an image capturing process when the subject is in a range where the display lamp is visible and, also, can recognize to be out of the image capturing angle of view when the subject is located at a position where the display lamp is invisible.
