  Moreover, what supports the back surface (lower surface) side of the terminal 21 of the attitude | position which the lower end side was supported by the back side receiving part 22b and inclined back diagonally downward is the front side receiving part shown in the 1st, 2nd embodiment mentioned above. Instead of 22a, it becomes a portion (mounting surface 22c) located between the operation panel 16 and the display panel 17 on the inclined surface of the front panel 11a.

  When the terminal 21 is placed flat on the mounting surface 22c with the back side thereof being along the mounting surface 22c, the terminal 21 is stably supported in a tilted forward tilted posture.

  In other words, this example includes the rear side receiving portion 22b as in the first and second embodiments. On the other hand, in the first and second embodiments, the lower side (back side) of the terminal 21 supported by the lower side (rear side) is supported by the rear side receiving part 22b. Although the receiving portion 22b is provided, in this example, a placement surface 22c is provided as the lower surface side supporting portion, and the same effect is obtained.

  All parts of the embodiment shown in FIG. 6 other than those described above are the same as those in the first and second embodiments, and the common reference numerals indicate the same parts and members.

  Furthermore, according to such a configuration, if the entire rear surface of the terminal 21 is placed in contact with the lower receiving portion 22c and the left and right sides are surrounded by the operation panel 16 and the display panel 17, the support is more stably supported. At the same time, the display surface of the terminal 21 is substantially the same plane in the same direction as the display surface of the display panel 17 on the work machine side, so that it is easy to read both screen information.

  Further, the inclined upper surface of the front panel 11a is also used as the mounting surface 22c, and there is no need to install or form a special member other than the rear side receiving portion 22b, which is advantageous in terms of cost.
