<p>PURPOSE:To detect the displacement of a camera main body in a non-contact state by making the incident position of a detecting light in a light receiving means deviate in the case that the camera main body is rapidly moved by the blurring, etc., caused by a photographer and detecting the displacement of the camera main body based on the incident position. CONSTITUTION:A displacement detecting sensor 10 is supported by plural supporting members 56 in the camera main body 54 so as to be freely rotated, and in the only case that the abnormal displacement occurs in the camera main body, the slide occurs between a spherical main body part 42 and a supporting ball 56a. In a photographing action, an LED 44 positioned on the upper part of the main body part 42 is driven to emit light, which is guided to the object side by a half mirror 50a, and the reflected light is guided to a light receiving sensor 48 passing through a prism 50. Then, in the case that the camera main body 54 is rapidly moved because of the blurring, etc., caused by the photographer, the deviation occurs between the main body part 42 and the supporting member 56, and the detecting light reflected on the object is made incident on the position which is deviated from the central part of the light receiving sensor 48. Thus, the displacement of the camera main body 54 is detected based on the deviation.</p> |
