PROBLEM TO BE SOLVED: To provide an ultrasonograph having high operability of locking of wheels and raising/lowering of an operation section.SOLUTION: This ultrasonograph 1 includes: a wheel locking mechanism 50 which includes a wheel locking pedal 51 and is changed over between a state of locking the wheels 41 and a state of unlocking the wheels 41 according to a treading operation of the wheel locking pedal 51 and an operation-section raising/lowering mechanism 60 which includes an operation-section raising/lowering pedal 61 and is changed over between a state of allowing the raising/lowering of the operation section 20 and a state of locking the raising/lowering of the operation section 20 according to the treading operation of the operation-section raising/lowering pedal 61. The wheel locking pedal 51 includes treading parts 51a and 51b which are disposed in both sides of a treading part 61a of the operation-section raising/lowering pedal 61, and a connecting part 51c which connects both-side treading parts 51a and 51b in such a manner as straddling over the operation-section raising/lowering pedal 61.COPYRIGHT: (C)2011,JPO&INPIT【課題】車輪のロックおよび操作部の昇降について操作性の高い超音波診断装置を提供する。【解決手段】超音波診断装置1は、車輪ロック用ペダル51を含み、車輪ロック用ペダル51の踏み込み操作に応じて、車輪41をロックする状態と、車輪41のロックを解除する状態とに切り替わる車輪ロック機構50と、操作部昇降用ペダル61を含み、操作部昇降用ペダル61の踏み込み操作に応じて、操作部20の昇降を許容する状態と、操作部20の昇降をロックする状態とに切り替わる操作部昇降機構60と、を有する。車輪ロック用ペダル51は、操作部昇降用ペダル61の踏み込み部61aの両側に配置された踏み込み部51a,51bと、操作部昇降用ペダル61を跨ぐように両側の踏み込み部51a,51b同士を連結する連結部51cと、を含む。【選択図】図1
