Abstract

PURPOSE: To obtain a device which is simple in structure and also high in accuracy, by providing the means for generating an electric signal corresponding to the position on which an incident light impinges through the thin hole of the light shielding plate.
CONSTITUTION: A light which has passed through the front glass 5 is condensed by the condenser lens 6, and after that, it is divided by the first semipermeable mirror 7a, one of them impinges on the photoelectric cell 11, makes the luminous intensity indicate to indicator 14, and the other light is further divided by the second semipermeable mirror 7b. One divided light irradiates the photoelectric conversion element 10a in a thin belt shape through the slit 8a. The irradiation position of this thin belt shape in the upper and lower directions is varied in accordance with the incident angle, an output signal is output from the conversion element 10a in accordance with the varied position, it is input to the upper and lower optical axis meter 17a, and the angle of the optical axis in the upper and lower directions is displayed. The other divided light is input to the photoelectric conversion element 10b through the upper slit 8b, and the angle of the optical axis in the right and left directions is displayed in the same way.
