PURPOSE:To make it possible to simplify an input circuit, by dividing the single output of a light receiving element, which is stored in a memory circuit, by the added output of two light receiving elements, and providing an operation circuit, which obtains the distance data of an object. CONSTITUTION:The first output of a distance-measuring-data generating means 1 is sent to a signal processing circuit 3 by a control means 2. The output of the signal processing circuit 3 is sent to a switching means 4, which is controlled by the control means 2 and held. The distance-measuring-data generating means 1, which is controlled by the control means 2, sends the second output to the signal processing circuit 3. The output of the signal processing circuit 3 is sent to a computing means 6 without passing through the memory means 5 by the switching means 4, which is switched by the control means 2. At the same time, the signal of the memory means 5 is sent to the computing means 6 by the control means 2. Thus the computation is performed. The computed result is judged by a distance judging means 7. The result is sent to the rear stage as the distance data. |
