To provide an ultrasonic video display device that reduces deviation in the drive timing of individual vibrators of an array probe.SOLUTION: An array type ultrasonic transmitter receiver according to the present invention transmits/receives an ultrasonic wave by an array type probe having a plurality of vibrators 21 to generate an ultrasonic beam. The array type ultrasonic transmitter receiver is constituted to include a control unit 11 that adjusts the output timing of a pulse signal generation unit 12 that outputs a pulse signal to drive the plurality of vibrators by a drive command signal, eliminates pulse signal output variation due to the difference in characteristics of the individual hardware pieces of the pulse signal generation unit, and equalizes the output timing of the pulse signals to drive the vibrators.SELECTED DRAWING: Figure 1 【課題】アレイプローブの個々の振動子の駆動タイミングのずれを低減する超音波映像表示装置を提供する。【解決手段】本発明のアレイ型超音波送受信装置は、超音波ビームを生成する複数の振動子２１を有するアレイ型プローブにより超音波を送受信するアレイ型超音波送受信装置であって、駆動指令信号により複数の振動子を駆動するパルス信号を出力するパルス信号生成部１２の出力タイミングを調整して、パルス信号生成部の個々のハードウェアの特性の違いによるパルス信号の出力バラツキを解消し、振動子を駆動するパルス信号の出力タイミングを均一化する制御部１１を備えるようにした。【選択図】図１
