制御することを特徴とするストツプウオツチ。 A reference signal generation circuit that outputs a reference signal, a stopwatch measurement circuit that counts the reference signal output from the reference signal generation circuit and measures elapsed time, and a first control for controlling the operation of the stopwatch measurement circuit. a display device for displaying measurement contents of the stopwatch measurement circuit; a timer circuit that operates based on the output of the first control circuit; and an alarm sound that outputs an alarm sound at regular intervals while the timer circuit is operating. In a stopwatch comprising a generation circuit and a second control circuit for controlling the output of the alarm sound generation circuit, when the stopwatch measurement circuit is in measurement operation, the stopwatch measurement circuit is in the middle of the output at the time of the output of the first control circuit. The measurement information is fixedly displayed on the display device during operation of the timer circuit operated by the output signal of the first control circuit, and the output of the alarm sound generation circuit is controlled by the second control circuit. A stopwatch characterized by control.
