In the conventional ultrasonic diagnostic apparatus, an operation panel that can be moved up and down by an elevating mechanism is provided so as to protrude greatly in front of the housing so that the housing does not hit the operator's knee when operating in a sitting position. Devised. However, in these conventional examples, only the operation panel is moved up and down while the monitor remains on the upper surface of the housing, and therefore the angle of the monitor must be changed according to the operation in the standing posture and the operation in the sitting posture. In addition, even if the angle of the monitor is changed, the line of sight of the operator looking at the monitor is different, and there is a problem of forcing the operator to operate in an unreasonable posture.

Further, in the conventional example, since the operation panel protrudes in front of the housing, the installation area is increased by this protrusion. In addition, there is a problem that the ultrasonic diagnostic apparatus having the protruding operation panel also increases the possibility that the operation panel will hit an obstacle during movement. For this reason, consideration must be given to protecting these operation panels.

In addition, since the casing of the conventional example is based on a box shape, a connector device or the like for connecting a probe is arranged vertically or horizontally on a vertical surface formed on the front face of the casing. For this reason,
Since these connector devices are arranged in a deep rear position below the operation panel projecting forward, there is a problem that these operations are difficult to perform.

Furthermore, since the frame of the conventional example is based on a box shape, when the casing is brought close to the subject sleeping on the bed, the vertically rising casing surface blocks the view of the subject. Become
There is a problem that makes the subject feel closed.

Further, the operation panel of the conventional ultrasonic diagnostic apparatus includes a trackball as a coordinate pointing device. Since this trackball does not require a wide operation surface unlike a mouse, it can be said to be an optimum coordinate pointing device for this kind of compactly arranged ultrasonic diagnostic apparatus. However, in the conventional example in which the operation panel can be swung left and right, the position of the trackball corresponds to the rotation of the operation panel because the trackball is disposed at a position away from the rotation center of the operation panel. There is a problem that it is difficult to operate because it moves greatly.

Therefore, an object of the present invention is that an operation device having a group of operation switches fits compactly on the upper surface of the main body housing during operation or movement in a standing posture, and the operation device is arranged forward for operation in a sitting posture. Therefore, an object of the present invention is to provide an ultrasonic diagnostic apparatus excellent in operability and mobility.

In order to achieve the above object, an ultrasonic diagnostic apparatus according to the present invention includes a main body housing, an operating device including an operation switch group, and a movable arm that connects the main body housing and the operating device. The operating device includes a first casing having an operation switch group, a second casing having an operation screen and a monitor screen for displaying a scanner image, and the second casing with respect to the first casing. The main body housing includes an inclined surface that inclines backward from the front surface to the upper surface, and the movable arm includes an elevating function mechanism unit that moves the operating device along the inclined surface. To.

Further, the movable arm moves the position above the inclined surface from the first position that is located above the inclined surface and within the projection area of the main body housing while maintaining the posture of the operating device. The operating device is movably supported as a path through a lifting function mechanism that moves at a position below the inclined surface and that can move in a second posture in which at least a part of the main body is projected from the main body housing.

According to the present invention, the first operation device having the operation switch group is positioned above the inclined surface.
In the posture, the operating device is at a high position above the main body housing, and in the second posture in which the operating device is positioned below the inclined surface, the operating device is placed at a lower position in front of the main body housing. Since it can be positioned overhanging from the main body chassis, the operation device fits compactly on the upper surface of the main body chassis when operating or moving in a standing position, and for operation in a sitting position, the operation device is placed forward and operated. And mobility can be improved.
