Measuring device

A measuring device comprising:

• a pair of rangefinding sensors arranged at a predetermined distance from each other
• a photoelectric converter disposed between said pair of rangefinding sensors;
• a composite optical part including a pair of rangefinding lens portions for guiding light rays to said pair of rangefinding sensors, and a predetermined optical functional member for guiding light rays to said photoelectric converter, said pair of rangefinding lens portions and said predetermined optical functional member being integrated together;
• and
• a holding member that holds said rangefinding sensors, said photoelectric converter, and said composite optical part;
• wherein said rangefinding lens portions and said optical functional member of said composite optical part are coupled so as to restrain light rays entering one of said rangefinding lens portions and said optical functional member and exiting from the other one of said rangefinding lens portions and said optical functional member from entering one of said rangefinding sensors and said photoelectric converter corresponding to the other one of said rangefinding lens portions or said optical functional member;
• and
• wherein said rangefinding lens portions and said optical functional members are coupled in a fashion being offset in an optical axis direction of the measuring device.
