ABSTRACT:
A light detector is disclosed which comprises a light-receiving section adapted to receive a measuring light beam at a front face thereof and to photoelectrically convert the light beam thus received and a display section adapted to display a measurement result on the basis of an output from the light-receiving section. The display section is constituted by a pair of display segments each having at least one displaying face on a respective one of side faces which are formed on opposed sides of the light-receiving section sandwiching it therebetween and are inclined with respect to the front face in such a direction that back faces thereof approach to each other.
