る同期監視装置。An ultrasonic sounder that measures water depth is equipped with at least a clock oscillator whose minimum unit is the minimum unit for measuring water depth or its accuracy, and the clock pulses of the clock oscillator are divided into various frequencies to drive a synchronous motor, etc. None, a detection circuit for detecting the speed is provided in part of the drive mechanism of the synchronous motor or part of the drive belt, and the detection signal causes the clock pulses from the clock oscillator to be counted, and the count number is equal to the predetermined count number. A simple arithmetic circuit is used to calculate whether or not the speed is within the range, and if the speed is within the synchronous speed, a ``synchronization OKJ'' signal is issued, and if the speed is not within the synchronous speed, a ``out of sync'' signal is generated. death,
In order to display this signal on a part of the recording paper or on an independent display device, a signal detection circuit 10, a gate signal circuit 11, a clock counter 12, an arithmetic circuit 13, a signal generation circuit 1
