Abstract

PURPOSE:To make the moving speed of a recording pen constant and make the change in the recording range of echo sounding possible by transferring the waveform of the received wave stored in a memory to a holding and read-out device then reading it out at the speed corresponding to the range and recording depth. CONSTITUTION:The waveform of ultrasonic reception waves from a receiving amplifier 6 is stored in a waveform storage device 17. This storage is transferred from a storage device 7 to a detector 8 in subsequent echo-sounding scanning periods because a storage device 17 and a holding and read-out device 18 are synchronously controlled by a timing pulse generator 1 controlling the generation of transmission pulses. Further in the subsequent echo sounding scanning period, the contents of the device 18 are read out at the speed corresponding to the range synchronously with the start of the forward movement of a recording pen, whereby depth is recorded. Hence, it is possible to change the range of echo sounding while maintaining the speed of the recording pen constant, and the constitution of the sounder is made simple.
