PROBLEM TO BE SOLVED: To provide a space-saving and low-cost contact preventing mechanism for an intraocular pressure measuring device.SOLUTION: The intraocular pressure measuring device includes: a spraying portion for spraying a gas to the cornea of an eye to be examined and a pressure detecting portion for detecting the pressure of the gas sprayed by the spraying means. The device measures an intraocular pressure on the basis of an amount of deformation of the cornea caused by the sprayed gas by the spraying portion and a pressure detected by the detecting means. The intraocular pressure measuring device further has an elastic member having elasticity and filled with the gas in the inside, and determines whether an outside article contacts the elastic member or not on the basis of a change in pressure inside the elastic member detected by the pressure detecting means.COPYRIGHT: (C)2013,JPO&INPIT【課題】眼圧計測装置において、省スペース、且つ、低コストの接触防止機構を提供する。【解決手段】眼圧計測装置は、被検眼の角膜に対して気体を吹き付ける吹き付け部と、吹き付け手段によって吹き付けた気体の圧力を検出する圧力検出部とを有し、吹き付け部による気体の吹き付けによって生じた角膜の変形量と、圧力検出部により検出された圧力とに基づいて、眼圧を計測する。眼圧計測装置は、更に、内部を気体で充填された弾性を有する弾性部材を有し、圧力検出部により検出された弾性部材の内部の圧力変化に基づいて外部物体の前記弾性部材への接触の有無を判定する。【選択図】 図2
