Abstract

PURPOSE:To prevent miscounting and perform correct counting, by installing plural means which detect the existence of bodies and performing counting through processing the signals from the detecting means. CONSTITUTION:For example, detecting means of boarding passes is stated below. Two pairs of lamps 1a and 1b plus phototransistors 2a and 2b are prepared, and each phototransistor 2a and 2b is connected to each flip-flop 8a and 8b through each amplifier 4a and 4b plus inversion gate 7a and 7b, respectively. An AND gate 9 is installed on the midway to the flip-flop 8b. In this construction, when a boarding pass 3 is inserted, the phototransistor 2a detects it and the flip-flop 8a is set. When the boarding pass 3 is inserted further, an one-shot 10 is operated by the rise of the flip-flop 8b. If the boarding pass 3 is taken off, flip-flops 8a and 8b are reset by a gate 11 which takes the AND of the output of the amplifiers 4a and 4b.
