When the mobile device 110 and the data collector 120 are to be used in this state, when the cover 173 is opened by rotating the cover 173 about the horizontal axis 173c, the position fixing ball 174 elastically installed by the spring 174a. May be separated from the first position fixing groove 175a and inserted into the second position fixing groove 175b or the third position fixing groove 175c, thereby opening the cover 173 as shown in the imaginary line. It can be adjusted, and can maintain the open state of the cover 173.

As described above, the mobile device 110 and the data collector 120 can be used while the cover 173 is open, and sunlight is blocked by the cover 173, so that the mobile device 110 and the data can be interrupted by light interference. The screen of the collector 120 can be prevented from being seen, and even when it rains or snow during use, the mobile device 110 and the data collector 120 can be prevented from directly hitting the rain or snow. Or failure can be prevented.

In addition, the present invention, it is very convenient to hold the mobile device 110 and the data collector 120 integrated with one hand by the handle 177 provided at the bottom of the angle adjustment bracket 176 to operate with the other hand. In addition, by using the fixing forceps 178 provided below the handle 177 as shown in Figure 8 it is possible to fix the integrated case 170 to the surrounding structure (S), the user is It can be used freely, and thus can also serve as a memo while using the mobile device 110 and the data collector 120.

In addition, when the adjustment screw 176a for fixing the mounting bracket 171 and the angle adjustment bracket 176 is released, the mounting bracket 171 may be rotated with respect to the angle adjustment bracket 176, thereby mounting the mount 171 In the use of the mobile device 110 and the data collector 120, the mobile device 110 and the data collector 120 can be adjusted at an angle convenient for the user to operate while watching the screen as shown in the virtual line of FIG. Convenience can be maximized further.
