At this time, the connection protrusions 26a and 26b of the panel base 22 are drawn rearward by the drive groove 44c of the advance / retreat member 44, and the display panel 20 is guided to the display panel guide portion 25 provided in the housing 11, The housing 11 is housed in the housing 11 and is in the housing posture (ii).

  As shown in FIG. 10, when the display panel 20 reaches the storage posture (ii), the rear forcing portion 86a on the left sliding link 76a is moved backward by the rear pressing portion 31a formed on the left rear portion of the panel base 22. The rear forcing part 86b on the right sliding link 76b is pushed rearward by the rear pressing part 31b formed on the right rear part of the panel base 22. Therefore, both the left sliding link 76a and the right sliding link 76b are moved rearward, and the rotation biasing link 71a is opposed to the biasing force of the spring member 73a by the connecting groove 77a of the sliding link 76a. The rotating biasing link 71b is forcibly rotated counterclockwise against the biasing force of the spring member 73b by the connecting groove 77b of the sliding link 76b.

  As a result, the lid support member 61 is pushed forward by the elastic link 75a and the elastic link 75b. The sliding projection 62 a of the lid support member 61 is moved to the front end of the rising guide portion 66 b of the upper guide elongated hole 66 of the lid member guide portion 65 shown in FIG. 2, and the sliding projection 63 a is moved to the lower guide elongated hole 67. When the lid member 60 is moved to the front end of the ascending guide portion 67b, the lid member 60 is lifted above the ceiling portion 12 of the housing 11. Then, the moving area 18 of the display panel 20 whose front and rear width dimension is W0 is shielded by the lid member 60, and the lid member 60 is lifted from below into the opening 101 of the main body panel 100 as shown in FIG. Thus, the opening 101 is closed. By closing the opening 101 with the lid member 60, it is possible to prevent foreign matter from falling into the housing 11.

  As shown in FIG. 2, the connection protrusions 27 a and 28 a provided on the panel base 22 are inserted into connection long holes 36 b and 36 d formed in the support base 36 of the connection moving part 35, and connected and moved with the panel base 22. The part 35 is connected. Therefore, when the display panel 20 moves back in the housing 11 to the storage posture (ii), the connection moving unit 35 moves back in the housing 11 following this. Since the wiring member 48 connected to the circuit board 37 mounted on the connection moving part 35 can be bent and deformed from the inside of the rear opening part 17b of the housing 11 to the rear side, bending stress acting on the wiring member 48 is applied. It can be mitigated.

  Moreover, when the connection moving part 35 moves to the last part, the connector provided in the circuit board 37 will oppose the inside of the rear part open part 17b. In the operation for attaching the display device 10 to the inside of the main body panel 100, the plugs 53 and 54 of the wiring member 48 are moved to the circuit board by moving the display panel 20 to the storage position (ii) as shown in FIG. 37 can be directly connected to the connector.

  When an operation for projecting the display panel 20 is performed by an operation unit (not shown), the motor 42 of the advance / retreat drive mechanism starts, the screw shaft 41 rotates, and the advance / retreat member 44 starts to move forward. Since the connecting projections 26 a and 26 b of the panel base 22 are pushed forward by the drive groove 44 c of the advance / retreat member 44, the display panel 20 is guided to the display panel guide portion 25 formed on the side plates 14 and 15 of the housing 11. And move forward toward the protruding posture (i).

  As shown in FIG. 6, immediately after the display panel 20 starts to advance from the storage position (ii), the rear pressing portions 31a and 31b of the panel base 22 are rear forcing portions 86a provided on the sliding links 76a and 76b. , 86b. At that moment, the rotation urging links 71a and 71b are rotated clockwise by the urging force of the spring members 73a and 73b, and the lid support member 61 and the lid member 60 are pulled backward via the elastic links 75a and 75b. It is burned. The lid support member 61 is guided by the lid member guide portions 65 provided on the side plates 14 and 15 of the housing 11 and moves rearward, and the lid member 60 is moved to the moving area 18 of the display panel 20 and the opening of the main body panel 100. It moves quickly to the open position (v) that is out of the part 101.

  Immediately after the display panel 20 starts to move forward from the storage posture (ii), the lid member 60 is quickly moved by the urging force of the spring members 73a and 73b to move to the open position (v), and the moving region 18 and the opening are opened. Part 101 is quickly opened. Therefore, inconvenience that the display panel 20 hits the lid member 60 while the display panel 20 moves to the protruding posture (i) through the inclined posture (iii) shown in FIG. 6 and the inclined posture (iv) shown in FIG. Does not occur.

  Thereafter, the advance / retreat member 44 is advanced by the rotation of the screw shaft 41, and the display panel 20 protrudes upward from the opening 101 of the main body panel 100 to be in the protruding posture (i). At substantially the same time, as shown in FIG. 9, the forced protrusions 85a and 85b are pushed forward by the pressing portions 44d and 44e of the advance / retreat member 44, and the forced link 81a and the forced link 81b are rotated to slide the link. 76a and 76b are moved backward. Therefore, the rotation urging links 71a and 71b are rotated counterclockwise against the elastic force of the spring members 73a and 73b, the elastic links 75a and 75b are advanced, and the lid support member 61 is moved forward. . Then, as shown in FIGS. 3 and 4, the front end portion of the lid support member 61 or the lid member 60 hits the rear end portion of the display panel 20 in the protruding posture (i).

  The lid support member 61 or the lid member 60 cannot move further forward than this, and on the other hand, the rotational force in the counterclockwise direction is applied to the rotation biasing links 71a and 71b by the rotational force of the forced link 81a and the forced link 81b. Therefore, the elastic links 75 a and 75 b are bent by elastic deformation, and the front end portion of the lid support member 61 or the lid member 60 is pressed against the base end portion of the display panel 20. Therefore, it is difficult to form a gap between the display panel 20 and the lid member 60, and the rear opening area of the opening 101 of the main body panel 100 that is not occupied by the display panel 20 is reliably closed by the lid member 60. It comes to be.

  On the other hand, as shown in FIG. 3, when the display panel 20 is in the projecting posture (i), the protrusion 32 formed on the front surface of the panel base 22 is below the front edge 101 a of the opening 101 of the main body panel 100. The narrow gap between the front edge portion 101a and the display panel 20 is also covered from below.

  The elastic links 75a and 75b may have a structure in which only a part can be elastically deformed and the other part has rigidity. Alternatively, each of the elastic links 75a and 75b may be composed of two members, and these two members may be connected via a spring to be elastically contracted and deformed so as to shorten the length.

  In the embodiment, the connection moving unit 35 on which the circuit board 37 is mounted is connected to the display panel 20 and moves inside the housing 11 following the movement of the display panel 20. 35 may be connected to the advancing / retracting member 44, and the connecting / moving part 35 may move back and forth following the advancing / retracting member 44.
