Provided is a notebook-sized ultrasonic diagnosis device configured so that a display housing provided with a display panel can move independently of a body housing provided with an operation panel and so that both the display housing and the body housing operate integrally with each other. This ultrasonic diagnosis device comprises two housings which can be connected to and separated from each other, the two housing being a display housing (10) which is provided with a display panel and an operation housing (20) which is provided with an operation panel. The housings respectively have handle sections (41, 42). The handle sections of the housings function as connection sections for connecting the two housings. When the two housings are stacked and connected, the handle sections join together to form a single handle. The handle section (41) provided to the display housing (10) is mounted so as to be capable of rotating relative to the display housing (10), and the handle section (41) functions as a support base when the display housing (10) is separated from the operation housing (20) and installed as a single unit or functions as a handle held by the operator.Linvention porte sur un dispositif de diagnostic par ultrasons de la taille dune tablette, lequel dispositif est configuré de telle sorte quun boîtier daffichage comportant un panneau daffichage peut se déplacer indépendamment dun boîtier de corps comportant un tableau dactionnement, et de telle sorte quà la fois le boîtier daffichage et le boîtier de corps fonctionnent intégralement lun avec lautre.
