  The display panel 2 is composed of a liquid crystal display panel, for example, and displays, for example, various measurement values through the fluoroscopic unit 12.

  The holder 3 is made of, for example, milky white synthetic resin and holds the display panel 2.

  In the region corresponding to the boss portion 13 of the holder 3, an attachment portion 31 is formed so as to overlap the boss portion 13, and a first screw insertion portion 32 corresponding to the screw 8 is formed in the attachment portion 31.

  The holder 3 continues to the spacer member 6 through the flexible hinge 33.

  The first circuit board 4 serves to electrically function the display panel 2 and is disposed on the back surface of the holder 3.

  A second screw insertion portion 41 corresponding to the first screw insertion portion 32 is formed on the circuit board 4.

  The second circuit board 5 also has the same function as the first circuit board 4, but is divided from the first circuit board 4 in order to reduce the dimension in the planar direction, and the first circuit board 5 is interposed via the spacer member 6. 4 and laminated.

  A third screw insertion portion 51 corresponding to the second screw insertion portion 41 is formed on the circuit board 5.

  The spacer member 6 is made of the same synthetic resin as the holder 3 and is continuous with the holder 3 through the flexible hinge 33.

  The spacer member 6 is formed with a fourth screw insertion portion 61 corresponding to the second and third screw insertion holes 41 and 51.

  The cover 7 is made of the same synthetic resin as the holder 3 and the spacer member 6, closes the opening of the housing 1, and displays the display panel 2, the holder 3, and the first and second circuit boards 4 between the housing 1. , 5 and a space for accommodating the spacer member 6 is formed.

  A fifth screw insertion portion 71 corresponding to the fourth screw insertion portion 61 is formed in the cover 7.

  Further, the cover 7 is connected to the spacer member 6 through the flexible hinge portion 72, whereby the cover 7, the spacer member 6, and the holder 3 become a single part continuous through the flexible hinge portions 33 and 72. It is.

  The display device configured as described above includes the screwing portion 14 of the housing 1, the first screw insertion portion 32 of the holder 3, the second screw insertion portion 41 of the first circuit board 4, and the fourth of the spacer member 6. The first screw insertion portion 32 to the fifth screw are aligned with each other, the screw insertion portion 61 of the second circuit board 5, the third screw insertion portion 51 of the second circuit board 5, and the fifth screw insertion portion 71 of the cover 7. The housing 8, the holder 3 that holds the display panel 2, and the first and second circuit boards 4 through the common screw 8 are rotated and inserted into and fixed to the screw-fastening portion 14. , 5, the spacer member 6, and the cover 7 are assembled and fixed. In addition, the fixing location by such a screw 8, the screwing part 14, and the 1st screw insertion part 32-the 5th screw insertion part 71 is set at two places on a diagonal line.

  As described above, in the present embodiment, the housing 1 having the see-through portion 12, the display panel 2 disposed so as to be visible through the see-through portion 12, the holder 3 holding the display panel 2, the circuit boards 4 and 5, Cover 7 that closes housing 1, and housing 1, holder 3, and cover 7 with display panel 2, holder 3, and circuit boards 4, 5 housed in a space formed by cover 7 and housing 1. In the display device including the screws 8 to be fixed, the circuit boards 4 and 5 are fixed to the housing 1, the holder 3, and the cover 7 through the screws 8, whereby the housing 1, the holder 3, the cover 7, and the circuit board 4. , 5 can be fixed with a common screw 8, so that fixing points can be consolidated, thereby improving assembly workability and securing space.
