(How to use the head-up display device 10)
Next, a method for using the head-up display device 10 having the above-described configuration will be described.
As shown in FIGS. 1, 9, and 10, the combiner 30 and the shielding plate 110 are accommodated in the main body 20 when the lid 40 is closed.

When the combiner 30 is used, the first lid 120 may be pushed down toward the main body 20.
When the first lid 120 is pushed up, the lock state of the lock mechanism 70 is released.
That is, the trace pin 160 located in the heart cam-shaped lock part 123b of the cam groove 123 is pulled out of the lock part 123b and proceeds to the sliding part 123a that extends long along the rotation direction of the first arm part 121. Proceed along the sliding part 123a.

Therefore, the first lid 120 can be rotated, and the combiner 30 connected to the first lid 120 by the first link 140 can be rotated.
For this reason, the combiner 30 protrudes upward from the opening 21 of the main body 20 as shown in FIGS. 1, 3, 5, 7, and 8 by the spring force of the driving spring 60, and opens upright. Rotate toward the use position.

At this time, the first lid 120 is opened via the first link 140, and the second lid 130 is further opened via the second link 150.
At the same time, when the first lid 120 rotates in the opening direction, as shown in FIGS. 13 and 18, the gear portion 125 formed on the first arm portion 121 on the side without the first link 140 and the side surface of the main body 20. Due to the meshing of the rotary damper 91 fixed to the gear, the rotary damper 91 rotates and a braking force is applied. The braking force is also transmitted to the combiner 30 via the first link 140, and the combiner 30 opens quietly and slowly.

When the second lid 130 is opened, as shown in FIGS. 1, 7 and 8, the shielding plate 110 is also opened by the shielding plate spring 112, and between the opened second lid 130 and the main body 20. Shield the gap.

(Interference prevention operation of the first and second lids 120 and 130)
During the unlocking operation, the first lid 120 is pushed down toward the main body 20, but at this time, the second lid 130 connected via the second link 150 is prevented from rotating.

That is, when the first lid 120 is pushed down, the second link 150 moves. At this time, the movable shaft 152 of the second link 150 is not shown, but the connection hole 133 of the second arm portion 131 of the second lid 130 is not shown. By moving from the small-diameter portion 133a to the large-diameter portion 133b (clearance), transmission of rotational force between the second link 150 and the second lid 130 is blocked.
For this reason, when the first lid 120 is pushed down, interference with the free end of the first lid 120 can be prevented by adopting a structure in which the free end of the second lid 130 does not move.
(Storing method of combiner 30)
Next, when storing the combiner 30 at the use position, the first lid 120 may be closed by hand.

When the first lid 120 is closed, the combiner 30 rotates in the closing direction via the first link 140. At the same time, the second lid 130 rotates in the closing direction via the second link 150.
At this time, the shield plate 110 is pushed in the closing direction by being pushed by the second lid 130.
When the closed position of the first lid 120 is closed to a slight extent, the trace pin 160 advances from the sliding portion 123a of the cam groove 123 to the heart cam-shaped lock portion 123b as shown in FIGS.

At this time, the first lid 120 is pushed back slightly through the first link 140 by the spring force of the driving spring 60, and the trace pin 160 is locked to the heart cam-shaped lock portion 123b as shown in FIG. Then, the lock mechanism 70 is locked.
For this reason, the combiner 30 is accommodated in the accommodating part 22 of the main body 20, and the opening part 21 is obstruct | occluded by the 1st, 2nd lid 120,130 as shown in FIG.2, FIG8 and FIG.9.
(How to adjust the opening angle of the combiner 30)
When the opening angle of the combiner 30 is adjusted in the use position opened upright, the operation portion 182 of the drum 180 protruding from the upper surface of the flange portion 23 may be rotated as shown in FIG.

When the operating portion 182 is rotated, the eccentric cam portion 183 is integrally rotated, and the follower portion 124 that protrudes from the cam portion 183 and the first arm portion 121 of the first lid 120 into a substantially U-shaped curved surface shape. The contact position of is changed.
That is, when the follower portion 124 comes into contact with the circumferential surface of the cam portion 183 separated from the drum shaft 181, the first lid 120 rotates in the closing direction, and the combiner 30 moves in the closing direction via the first link 140. It rotates and the opening angle of the combiner 30 decreases.

In contrast, when the follower portion 124 comes into contact with the circumferential surface of the cam portion 183 approaching from the drum shaft 181, the first lid 120 rotates in the opening direction, and the combiner 30 is opened via the first link 140. And the opening angle of the combiner 30 increases.
The adjustment range of the opening angle of the combiner 30 is set to plus / minus 5 degrees, but is not limited thereto.
(Protection method against excessive opening of combiner 30)
When the combiner 30 is forcibly opened in the upright open use position, the link pin 142 of the first link 140 that is engaged with the engaging portion 192 of the stopper 190 is shown in FIG. Then, it moves in a direction to escape from the engaging portion 192 and disengages from the open surface.

For this reason, the connection state between the first link 140 and the first lid 120 is released, and transmission of the overload applied to the combiner 30 to the link mechanism 50 is interrupted.
On the other hand, when the overload applied to the combiner 30 is released, the combiner 30 tries to return to the initial position by the spring force of the drive spring 60. At this time, the stopper 190 is also rotated in the direction approaching the link pin 142 by the stopper spring 200.

  For this reason, the link pin 142 moves toward the engaging portion 192 while slidingly contacting the side surface of the stopper 190, and the stopper 190 is resisted against the spring force of the stopper spring 200 when the tapered shape 193 is disengaged. By pushing back a little, as shown in FIG. 21, it engages with the engaging portion 192 again. For this reason, the connection state between the first link 140 and the first lid 120 is restored.
