PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus excellent in operability and mobility by compactly settling an operation board on the upper surface of a housing during an operation in a standing posture and movement and arranging the operation board at the front during the operation in a sitting posture.SOLUTION: The ultrasonic diagnostic apparatus comprises a body housing 100 equipped with a movable wheel 101, an operation device 200 equipped with an operation switch group 400, and a movable arm 300 to connect the body housing 100 and the operation device 200. The body housing 100 includes an inclined surface 103 backwardly inclined from the front surface to the upper surface. The movable arm 300 movably supports the operation device 200 through an elevating/lowing function mechanism part 301 for moving it from a first posture Q1 at the upper position of the inclined surface 103 to be settled within the projection area of the body housing 100 so as to take a second posture Q2 at the lower position of the inclined surface 103 to be at least partially projected from the body housing 100 with the upper position of the inclined surface 103 as a moving path in the state of maintaining the posture of the operation device 200.COPYRIGHT: (C)2009,JPO&INPIT【課題】 立ち姿勢での操作や移動時には操作盤が筺体の上面にコンパクトに収まり、座り姿勢での操作では操作盤を前方に配置して、操作性や移動性に優れた超音波診断装置を提供する。【解決手段】 移動車輪101を備えた本体筺体100と、操作スイッチ群400を備えた操作装置200と、本体筺体100と操作装置200とを連結する可動アーム300とを含んで構成し、本体筺体100は、前面から上面にかけて後方に傾斜する傾斜面103を備え、可動アーム300は、操作装置200の姿勢を維持した状態で、傾斜面103の上方位置で、かつ、本体筺体100の投影面積内に収まる第1姿勢Q1から、傾斜面103の上方位置を移動路として、傾斜面103の下方位置で、かつ、本体筺体100から少なくとも一部を張り出す第2姿勢Q2を取り得るように移動させる昇降機能機構部301を介して操作装置200を移動可能に支持する。【選択図】 図1
