  FIG. 9 is a flowchart illustrating an example of the operation of the attachment member during maintenance of the display device.

  Here, the operation of the mounting member during maintenance of the display device 6 will be described.

  The mounting member 1 is fixed to the upper surface of the front panel of the vehicle, for example, by the base bracket 2. The display device 6 is used by being attached to the joint bracket 5 of the attachment member 1. Normally, the display device 6 is used in a state where the back surface of the display device 6 and the arm bracket 4 are closed. At this time, a predetermined screw inserted into a predetermined screw hole provided in the arm bracket 4 is replaced with a hole or notch (notch JA11, notch JB12, notch JC13) of the joint bracket 5 corresponding to the predetermined screw. ) To fasten the joint bracket 5 to the arm bracket 4. The predetermined screws are the screw JR14, the screw JA15, the screw JB16, and the screw JC17. That is, the predetermined screw is tightened via a hole corresponding to the screw JR14, a notch JA11 corresponding to the screw JA15, a notch JB12 corresponding to the screw JB16, and a notch JC13 corresponding to the screw JC17, respectively. 5 is fixed to the arm bracket 4. The predetermined screw and the corresponding notch (notch JA11, notch JB12, notch JC13) are screw JR14, screw JA15, screw JB16 and screw JC17, notch JA11, notch JB12, and notch. Not limited to JC13, it may be installed as appropriate. At this time, the pin A8 of the joint bracket 5 is inserted into the pin hole AA18 provided in the arm bracket 4, and the pin B9 of the joint bracket 5 is inserted into the pin hole AC20 provided in the arm bracket 4.

  Then, in step S1 of FIG. 9, when maintaining the display device 6, predetermined screws (screw JR14, screw JA15, screw JB16, and screw JC17) are loosened by the operation of the maintenance person.

  In step S2 of FIG. 9, the joint bracket 5 (display device 6) is slightly lifted (to the extent that the pin is pulled out) by the operation of the maintenance person, and the pin A8 is removed from the pin hole AA18. Then, the joint bracket 5 is rotated by 90 ° in the A direction around the central axis (the central axis of the screw JR14) provided on the arm bracket 4.

  At this time, the loosened screw JA15, screw JB16, and screw JC17 pass through the U-shaped notch JA11, the notch JB12, and the notch JC13, respectively, at the positions corresponding to these screws of the joint bracket 5. To do. For this reason, the joint bracket 5 can be rotated only by loosening without removing the screw.

  In step S <b> 3 of FIG. 9, the joint bracket 5 is temporarily fixed to the arm bracket 4 by the operation of the maintenance person. That is, the pin A8 of the joint bracket 5 is moved onto the pin hole AB19, the joint bracket 5 is lowered onto the arm bracket 4, and the pin A8 is inserted into the pin hole AB19. Thereby, what was in the state where the back of display 6 and arm bracket 4 were closed will be in the opened state. Even in the opened state, since the joint bracket 5 is temporarily fixed to the arm bracket 4 with a pin (pin A8), maintenance work can be performed without the joint bracket 5 falling off.

  Here, since the space between the back surface of the display device 6 and the arm bracket 4 is opened, the maintenance person can easily insert and remove the cable usually on the back surface. Further, maintenance work on the back surface can be performed without removing the display device 6 from the mounting member 1. Moreover, the quality of the maintained content can be confirmed by operating the display device 6 while temporarily fixing the joint bracket 5 to the arm bracket 4.

  In step S4 of FIG. 9, after performing the maintenance work, the joint bracket 5 (display device 6) is slightly lifted (to the extent that the pin comes off) by the operation of the maintenance person, and the pin A8 is removed from the pin hole AB19. Then, the joint bracket 5 is rotated 90 ° about the central axis of the arm bracket 4 in the B direction opposite to the A direction. At this time, the loosened screws JA15, JB16, and JC17 are fitted into the open portions of the notch JA11, the notch JB12, and the notch JC13 of the joint bracket 5.

  In step S <b> 5 of FIG. 9, the joint bracket 5 is temporarily fixed to the arm bracket 4 by the operation of the maintenance person. That is, the pin A8 of the joint bracket 5 is moved onto the pin hole AA18, the joint bracket 5 is lowered onto the arm bracket 4, and the pin A8 is inserted into the pin hole AA18. Thereby, what was in the state opened between the back surface of the display apparatus 6 and the arm bracket 4 will be in the closed state.

  In step S6 of FIG. 9, after the joint bracket 5 is temporarily fixed to the arm bracket 4 by the operation of the maintenance person, predetermined joints (screw JR14, screw JA15, screw JB16, and screw JC17) are tightened. Is permanently fixed to the arm bracket 4.

  As described above, the joint bracket 5 can be permanently fixed in a state where the joint bracket 5 is temporarily fixed to the arm bracket 4. For this reason, it is not necessary for the maintenance person to hold or support the display device 6 by hand or the like when performing the main fixing such as screw tightening, so that the maintenance work is facilitated and spread to the normal use state. Becomes easier.

  As described above, according to the third embodiment of the present invention, in addition to the effects acquired in the first embodiment, the following effects can be obtained. That is, when a notch is provided in the joint bracket so that the space between the back surface of the display device and the arm bracket 4 is opened, the screw for attaching the joint bracket to the arm bracket 4 passes through the opening of the notch. I tried to do it. For this reason, the joint bracket can be rotated simply by loosening without removing the screw, so that the maintenance work is facilitated and the maintainability is improved.

  Further, the joint bracket is temporarily fixed to the arm bracket with a pin (pin A8) provided on the joint bracket in a state where the back surface of the display device and the arm bracket are open. For this reason, even in the opened state, the joint bracket is temporarily fixed to the arm bracket by the pin (pin A8), so that the maintenance work can be performed without dropping the joint bracket.

  Furthermore, since the space between the back surface of the display device and the arm bracket is temporarily fixed, the maintenance person can easily insert and remove the cable normally on the back surface. Further, maintenance work on the back surface can be performed without removing the display device from the mounting member. Moreover, the quality of the maintained content can be confirmed by operating the display device while temporarily fixing the joint bracket to the arm bracket. This facilitates maintenance work and improves maintainability.

  In addition, the joint bracket can be temporarily fixed to the arm bracket after the joint between the rear surface of the display device and the arm bracket is closed. For this reason, since the maintenance person does not have to hold or support the display device by hand or the like when performing the main fixing such as screw tightening, the maintenance work is facilitated and the maintainability is improved.

  Furthermore, since the rotation of the joint bracket with respect to the arm bracket is locked by a Kensington lock, it is possible to prevent the display device and the mounting member from being stolen without using a special tool.
