Claim 4:
5. The inspection device according to claim 4,
wherein the controller is further configured to:
after outputting the instruction signal when the rate of decrease is equal to or higher than the first threshold, and an elapsed period since last update of the reference data is equal to or longer than a first particular period, re-determine the rate of decrease in response to receiving input of the completion signal;
when the re-determined rate of decrease is equal to or higher than the second threshold, output the instruction signal again, to repeat the output of the instruction signal until the re-determined rate of decrease becomes lower than the second threshold;
update the reference data, when the re-determined rate of decrease becomes lower than the second threshold while a number of times the instruction signal has been output is equal to or less than the first particular number of times;
update the reference data, when the re-determined rate of decrease is equal to or higher than the second threshold after the number of times the instruction signal has been output reaches the first particular number of times; and
not update the reference data, when the rate of decrease is equal to or higher than the first threshold, and the elapsed period since the last update of the reference data is shorter than the first particular period.
