PROBLEM TO BE SOLVED: To inhibit a reference deformable body from being displaced from an ultrasonic transmitting/receiving surface of an ultrasonic probe in screening.SOLUTION: A lower fixture 24 for the reference deformable body includes a lower frame body 30 and a lower engagement member 34. The lower frame body 30 is formed in a frame-shape along the peripheral edge of the ultrasonic transmitting/receiving surface 50 of the ultrasonic probe 1, and has a grasping surface 28 formed to abut to the rear surface of a guard member 22 of the reference deformable body 16. The lower engagement member 34 hangs from the surface opposite from the grasping surface 28 and has a locking part 32 to be locked to the ultrasonic probe. An upper fixture 26 includes an upper frame body 40 and an upper engagement member 44. The upper frame body 40 is formed in a frame-shape along the peripheral edge of a rectangular parallelepiped member 20 of the reference deformable body, and has a grasping surface 38 formed to abut to the front surface of the guard member of the reference deformable body. The upper engagement member 44 hangs from an end of the upper frame body and has a locking part 42 to be locked to the lower frame body. Projections 36 and 46 are formed on the grasping surfaces of the lower frame body and upper frame body respectively.COPYRIGHT: (C)2011,JPO&INPIT【課題】スクリーニングを行なった際に、参照変形体が超音波探触子の超音波送受信面からずれるのを抑制する。【解決手段】本発明の参照変形体の下部固定具24は、超音波探触子1の超音波送受信面50の周縁に沿って枠状に形成されるとともに参照変形体16の鍔部材22の裏面に当接する挟持面28が形成された下部枠体30と、挟持面28の反対側の面から垂設され超音波探触子に係止可能な係止部32が形成された下部係合部材34とを有して構成される。上部固定具26は、参照変形体の直方体部材20の周縁に沿って枠状に形成されるとともに参照変形体の鍔部材の表面と当接する挟持面38が形成された上部枠体40と、上部枠体の端部から垂設され下部枠体に係止可能な係止部42が形成された上部係合部材44とを有して構成される。そして、下部枠体及び上部枠体の挟持面には突起36,46が形成される。【選択図】図2
