  In the conventional portable ultrasonic diagnostic apparatus, the operation unit disposition surface formed on the upper surface of the main body casing is a flat flat surface, the first operation group mainly including a trackball is disposed in front of the operation unit disposition surface, and the rear thereof. A second operation group mainly including a keyboard capable of inputting characters to be arranged is arranged. That is, the operation switches are gathered in a compact manner on one operation unit arrangement surface. However, since a trackball does not require a wide operation surface like a mouse, it can be said that it is an optimal coordinate pointing device for a portable ultrasonic diagnostic apparatus, but there is a problem that the upper end of the trackball protrudes greatly from the operation unit arrangement. . In a portable ultrasonic diagnostic apparatus, a rotary knob is often used as an adjustment switch. For this reason, in the portable ultrasonic diagnostic apparatus, since the trackball and the rotary knob that greatly protrude from the operation unit arrangement surface protrude greatly from the operation unit arrangement surface, the downsizing is greatly hindered. Moreover, these trackballs and rotary knobs are arranged on the front side of the operation unit arrangement surface from the viewpoint of frequency of use. For this reason, these trackballs and rotary knobs obstruct the operation of the keyboard arranged behind them, and therefore, an unreasonable operation posture such as floating the hand to the operating operator and inputting it was forced.

  Further, in the portable ultrasonic diagnostic apparatus, it is necessary to attach a probe to the main body housing. However, since this connector is large, it is one of the obstacles to making the main body housing thinner.

  Accordingly, an object of the present invention is to provide a compact portable ultrasonic diagnostic apparatus excellent in operability.

  To achieve the above object, according to the present invention, in the portable ultrasonic diagnostic apparatus including a main body housing having an operation unit arrangement surface on an upper surface, the operation unit arrangement surface includes a first operation having a trackball.

That is, by forming the rear part of the extension part 106 on both sides formed on the rear side of the front arrangement surface 102 and the stepped part 104 with a large arc centered on the trackball 231, A wide flat surface portion 124 is formed on both sides of the rear, and the wide flat surface portion 124 can be used as a third palm rest 124 a for improving the operability of the second operation group 260.

  In addition, the inclined surface 105 and the both inclined surfaces 50a are formed by a large arcuate inclined surface 50b as the rear of the front arrangement surface 102 is formed by a large arc 123. If switches are arranged on the arcuate inclined surface 50b, the switches are arranged in an arcuate shape centered on the trackball 231 and on the inclined surface (the arcuately inclined surface 50b) rising rearward. Visibility and operability can be improved.

  8A is a longitudinal sectional view including a trackball, and FIG. 8B is a transverse sectional view including a main substrate. In FIG. 8, in this embodiment, even if both side step portions 104a are provided on both sides of the front arrangement surface 102, a two-stage structure with the rear arrangement surface 103 is ensured. An effect can be obtained. In addition, the second probe connector portion 50 a can be arranged in one extension portion 106 along with the probe connector portion 50. In addition, since the front portion placement surface 102 is surrounded by the inclined surface 50 and both side step portions 104a, operability can be improved by arranging switches on the inclined surface.

  Further, as shown by a broken line in FIG. 8B, the entire front arrangement surface 102 may be formed of a concave curved surface 124 (including an inclined surface) with the arrangement portion of the trackball 231 as the lowermost portion. good. That is, the front arrangement surface 101 is formed by a curved surface or an inclined surface that gradually rises from the center position of the trackball 231 toward the outside. As a result, the higher the amount of upward protrusion and the higher the frequency of use of the trackball 231, the more distant the other switches are arranged at higher positions, thus improving visibility and operability. be able to.
