PROBLEM TO BE SOLVED: To provide test equipment capable of easily and accurately performing inspection on the basis of an acoustic wave reflected on an eardrum.SOLUTION: The test equipment is the equipment for inspection based on an acoustic wave reflected on an eardrum, and comprises: a housing with an opening； a sound output part provided in the housing, and which outputs an acoustic wave through the opening； a sound detection part provided in the housing, and which detects the reflected acoustic wave output from the sound output part and reflected at a reflection position through the opening； and an imaging part provided in the housing, and which images the reflection position through the opening. In a direction along a center axis of the opening, the sound detection part is closer to the opening relative to the sound output part, and the imaging part is provided on a side separated from the opening with respect to the sound output part.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】鼓膜で反射した音響波に基づく検査を簡易かつ高精度に行うことを可能にする検査装置を提供する。【解決手段】本発明の検査装置は、鼓膜で反射した音響波に基づく検査のための検査装置であって、開口を有する筐体と、前記筐体内に設けられた、前記開口を介して音響波を発する音出力部と、前記筐体内に設けられた、前記音出力部から発せられて反射位置で反射した反射音響波を前記開口を介して検出する音検出部と、前記筐体内に設けられた、前記開口を介して前記反射位置を撮像する撮像部と、を有し、前記開口の中心軸に沿った方向において、前記音検出部は、前記音出力部に対して前記開口に近い側に設けられており、前記撮像部は、前記音出力部に対して前記開口から遠い側に設けられている。【選択図】図２
