Automatic range finding device |
摘要 |
An automatic range finding device has a light-emitting unit for emitting a slit of light as a beam toward a subject and a light-receiving unit for receiving light reflected from the subject, thereby to detect the subject distance based on the incident position of the reflected light received by the light-receiving unit. The light-emitting unit emits the slit of light slantwise relative to the image plane.
