    Patent number: 9532414
    Abstract: A trigger-signal-output part sets a burst time cycle to a time period N (integer of two or more) times as long as a constant first cycle, and outputs a trigger signal M (positive integer of N or less) times during an operation period so as to synchronize it with the first cycle, and does not output the trigger signal during a stop period except the operation period of the burst time cycle. Alternatively, a trigger-signal-output part sets a burst time cycle to a time period N times as long as an output cycle of a trigger signal in an operation period, and sets the operation period to a time period M times as long as the output cycle, and sets a stop period except the operation period of the burst time cycle to a time period generated by multiplying the output cycle by a difference between N and M.
