Abstract

PURPOSE:To raise the transmitting level of wave and eliminate discontinuity between images made by wave transmitting beam by rotating plural number of wave transmitting waves in one direction and projecting sound wave to the searching area. CONSTITUTION:By connecting the points 11-13 of a cross-bar switch CS, the output from an oscillator O is conveyed to vibration elements V3 and V4 through a delay point d1 and the output of d2 is conveyed to V2 and V5, the output of d3 to V1 and V6. And, by forming a plane wave SW1, SW1' which make a right angle to the center axis of V3 and V4, wave transmitting beams SB and SB', of which the center of V3 and V4 makes the directional axis, are obtained. Then, points 11- 13 are disconnected and 21-23 connected so that output of d1 is conveyed to V2 and V5, output of d2 to V3 and V4, V1 and V6, forming plane waves SW2 and SW2', thus obtaining wave transmitting beam with its directional axis at the center of V2 and V5. And by disconnecting 21-23 and connecting 31-33, 2 wave transmitting beams which have their directional axis at the center of V1 and V6 are obtained, forming wave trasmitting beams rotating in the opposite direction.
