PURPOSE:To reduce noise caused by accidental simultaneous counting by increasing the degree of freedom on the planning of an effective visual sight radius, by forming the circuit constitution of an address encoder from detector arrangement under a predetermined condition and an OR circuit. CONSTITUTION:In the input of a simultaneous count circuit of an arbitrary group A and the opposed group B coupled with said group A by said simultaneous count circuit, only N detectors adjacent to groups on the right side among detectors of A are related to only N detectors adjacent to groups on the left side among detectors of B. In the input of the simultaneous count circuit of A and the group C at the right end from A in the opposed group coupled with A by said simultaneous count circuit, only N detectors adjacent to groups on the left side among detector of A are connected to only N detectors adjacent to groups on the right side among detectors of C. OR outputs of N timing signals from these processing circuits are formed in an address encoder and supplied to the input of the simultaneous count circuit to operate N detectors of an arbitrary group. |
