Abstract

PURPOSE:To ensure a detection in the directions of both right and left sides with the size of one wave transmitter and receiver, by arraying oscillator elements of a wave transmitter and receiver through dispersing said elements to two series so as to secure the directivity in both right and left directions. CONSTITUTION:An oscillator element 22 with a sound wave reflector member 21 bonded on the surface opposite to the sound wave radiation surface and an oscillator element 24 with a sound wave reflector member 23 bonded on the surface opposite to the sound wave radiation surface are arrayed alternately in a one body and in such way that the directions of the radiation surfaces are opposite to each other. Thus the radiating direction 13 of the group of the element 22 is opposite to the radiating direction 14 of the group of the element 24.
