INTERFACE CIRCUIT, DETECTOR, AND GAME MACHINE

摘要

PROBLEM TO BE SOLVED: To cause the number of signals output when a pulse signal is input from a detection sensor to coincide with the number of game balls actually guided from a guide path to a game area.SOLUTION: An interface circuit 21 includes: a guide signal output circuit 22 for outputting a guide signal that indicates that a game ball is guided to a game area in response to the input of a pulse signal from a detection sensor 6 to the interface circuit 21 when an output prohibition signal is not input; an output prohibition circuit 23 for outputting the output prohibition signal to the guide signal output circuit until a prohibition time elapses after the time the guide signal is output; and an abnormality detection circuit 24 for outputting an abnormality signal that indicates that the detection sensor 6 is in an abnormal state when a time period during which the pulse signal is input from the detection sensor 6 exceeds an abnormality detection time.SELECTED DRAWING: Figure 6
