The present invention provides an ultrasonography containing a main body housing having transfer wheels. An operation device having switches, a movable arm to connect the main body housing to the operation device which has an inclined plane inclining rearward from a front face to an upper face; and the movable arm supports the operation device through an elevating function mechanical section to move the operation device.
1. An ultrasonograph comprising a main body housing, an operation device having operation switches, and a movable arm to connect the main body housing to the operation device,
wherein the main body housing has an arc shaped inclined face, wherein arc shaped is part of the circumference of a circle, inclining vertically and rearward from a front face portion to an upper face portion;
wherein the main body housing has an arm transfer groove inclining vertically and reward along the arc shaped inclined face, and the movable arm has an elevating function mechanical section so that the operation device is movable along the arc shaped inclined face by movement of the movable arm inclining upward toward the back, to slide and fix the operation device at a selectable position along the arc shaped inclined face; and
wherein the movable arm being fixed at one end so as to be rotatable around a rotation axis formed at a predetermined position in the arm transfer groove, so that the operation device is movable in a same direction as the arc shaped inclined face by rotation of the movable arm.
2. The ultrasonograph according to claim 1 , wherein the movable arm has the one end fixed and has another end which is free.
3. The ultrasonograph according to claim 2 , wherein the arm transfer groove, in which the one end of the movable arm is fixed so as to be rotatable around the rotation axis, is formed on one side in a front face of the main body housing.
4. The ultrasonograph according to any one of claims 2 , further comprising a posture maintenance mechanism for maintaining posture of the operation device when the movable arm is moved.
5. The ultrasonograph according to claim 4 ,
wherein the posture maintenance mechanism comprises a link mechanism for maintaining posture of the operation device when the movable arm is moved;
wherein the link mechanism comprises a first base section connected to the one fixed end of the movable arm and fixing the elevating function mechanical section to the main body housing, a second base section connected to the other free end of the movable arm and to which an attachment mechanical section is fixed, and a spring member for connecting a predetermined position of the first base section and the movable arm.
6. The ultrasonograph according to claim 4 , further comprising a cover for covering the arm transfer groove.
7. The ultrasonograph according to claim 1 , further comprising a cover for covering the arm transfer groove.
8. The ultrasonograph according to claim 1 , wherein the distance between the operation device and the arc shaped inclined face is kept constant.
9. An ultrasonograph comprising a main body housing, an operation device having operation switches, and a movable arm to connect the main body housing to the operation device,
wherein the main body housing has a circle-shaped inclined face, wherein arc shaped is part of the circumference of a circle, inclining vertically, rearward from a front face portion to an upper face portion,
wherein the movable arm has an elevating function mechanical section to move and fix the operation device along the circle-shaped inclined face, and a posture maintenance mechanism for maintaining posture of the operation device at a time of movement of the movable arm, and
wherein the operation device is movable along the circular shaped inclined face by movement of the movable arm, to assume a first posture when the operation device is located at an upper position of the circular shaped inclined face of the main body housing, and a second posture when the operation device is located at a lower position of the circular shaped inclined face of the main body housing, while inclining upward toward the back.
10. The ultrasonograph according to claim 9 ,
wherein the operation device is movable between the second posture and the first, while posture of the operation device is in the maintained state by the posture maintenance mechanism.
11. An ultrasonograph comprising a main body housing, an operation device having operation switches, and a movable arm to connect the main body housing to the operation device,
wherein the movable arm has an elevating function mechanical section to move the operation device along the main body housing and be fixed in selectable positions, while inclining the operation device upward toward the back, and a posture maintenance mechanism for maintaining posture of the operation device at a time of movement of the movable arm, and
wherein the movable arm is drawn into the main body housing and the operation device rises by a rotating operation of the movable arm.
