Apparatus for detecting obstacle

Abstract

Abstract PURPOSE:To make it possible to obtain an obstacle detecting apparatus large in the free degree of a plan, by providing a clock pulse generating circuit, a saw tooth generating circuit, a distance comparing circuit, a detector circuit and a latch circuit. CONSTITUTION:A saw tooth wave 20a is generated in synchronous relation to a clock pulse 2a outputted from a clock pulse generating circuit 2 by a saw tooth generating circuit 20 and voltage corresponding to the predetermined distance to an obstacle 6 and the voltage of the saw tooth wave are compared by distance comparing circuits 21-23 while the outputs of the distance comparing circuits 21-23 are latched by a latch circuit on the basis of a detector circuit 9 and a signal corresponding to the distance to the obstacle 6 is outputted. By this method, the free degree of a plan can be made large.
