<p>PURPOSE:To enable a roof mirror lens array to be always used at its optimum characteristic position by a method wherein an angle made by a reflecting surface of an optical path separation mirror with a surface containing an optical axis of a lens array is made variable. CONSTITUTION:A lens array 4, a diaphragm 3, and a roof mirror array 2 are engaged with a standard pin and a standard hole, and a unified unit component is fixed to inside a frame 6 of the roof mirror lens array. An optical path separation mirror 5 is so constructed as to be rotated by taking a line of intersecting said optical path separation mirror 5 with a surface containing an optical axis of the lens array 4 as a central line. Images of objects points O1, O2, of different image heights can be imaged at an image point I1 by rotation of the optical path separation mirror 5. Further, a line of intersecting a magnification image sensor 18 in which an illuminating light source 19 and a plurality of lines of photoelectric converting elements are arranged with a surface containing the optical path separation mirror 15 and an optical axis of the optical path separation mirror 15 and the lens array 14, is so constructed as to be rotated as a central (rotary) axis.</p> |
