PROBLEM TO BE SOLVED: To simplify the operation of changing from an open state to a storage state in a transportable ultrasound diagnostic apparatus wherein a body and an operation panel are both pivotable.SOLUTION: When turning an open operation panel 14 to an upright storage state, the surface panel member 90 of the operation panel is brought into contact with the case member 92 of the body 12. The body 12 is pushed by the operation panel 14 and the body 12 is also pivoted to an upright state. By the operation of pivoting the operation panel, the body is also pivoted and they are turned to the upright storage state.COPYRIGHT: (C)2009,JPO&INPIT【課題】本体と操作パネル双方が回動可能な可搬型超音波診断装置において、展開状態から格納状態とする操作を簡略にする。【解決手段】展開している操作パネル14を直立した格納状態とする際に、操作パネルの表パネル部材90が、本体12のケース部材92に接触するようにする。操作パネル14により本体12を押し、本体12も直立状態へと回動させる。操作パネルを回動させる動作により、本体も回動し、これらが直立した格納状態となる。【選択図】図7
