Abstract

PURPOSE: To count events occuring not regularly by providing a pulse generating means which generates pulses according to the count values of an auxiliary counter means.
CONSTITUTION: The outputs of a detection system 1 is used at the counting as well, but are counted by a counter 6 when the clock signal is 1 and by a counter 7 when 0 through a gate 5. A pulse generating circuit 8 generates the square wave pulses whose pusle width is the dead time α by the count value of the counter 6 with the time when the clock signal becomes 0 from 1 as the start point. It generates the square wave pulses by the count value of the counter 7 at the time when the clock signal becomes 1 from 0. As a result, the count value in a memory device 3 performs correction of count missing as given by the current count value based on the count value of 1 second immediate before.
