Abstract

PURPOSE: To substantially multiply the band dividing number of a range finder by providing interchanging means for interchanging the relative positions between the optical means of photosensitive means and a light receiving elment.
CONSTITUTION: In response to change-over signals, an electromagnetic coil 8b is energized to release a bell crank lever 9 from its attracted condition so that an ofjective lens 5 is shifted to the postion shown in imaginary lines. Then, the relative positions of the center of the lens 5 corresponding to the respective optical responding elements P4, ---, P8 of second sensing means 6 is varied to intercharge the finding range to a short zone shown at Z1', Z2' and Z3'. For the first finding range D1 obtained when the lens 5 of second sensing means 4 is placed at a position A shown in solid line, the lens 5 is interchanged to a positon B shown in imaginary lines thereby to make the range finding at a second finding range D2 possible.
