The driving force transmitted to the shaft 14 is transmitted to the right and left outer gear portions 20. The driving force transmitted to the gear unit 20 is transmitted to the main gear 30 via the driving gear 21. The main gear 30 starts to rotate in one direction (for example, clockwise in FIG. 11) by the driving force transmitted in this way.

  Below, the virtual reference point P which shows the rotation position of the main gear 30 is defined, and the relationship between the position of the reference point P and each operation | movement is also demonstrated. In the example shown in FIG. 11, the reference point P is located on the outer periphery of the main gear 30 and in the vicinity of the end of the first groove 33, and is located below the main gear 30 in the initial state. Below, each operation | movement of opening | release of the opening D1 by the cover part 2, the upward movement of the combiner 3, and tilting of the combiner 3 is demonstrated.

(Opening of the opening D1 by the lid part 2)
When the main gear 30 starts to rotate in one direction with the reference point P positioned below the main gear 30, the reference point P moves from the lower side to the front side of the main gear 30. Then, the boss 44 starts to move along the first groove 33 and moves from the vicinity of the rotation center 30 a of the main gear 30 toward the radially outer side of the main gear 30. The boss 44 starts to move from the vicinity of the rotation center 30 a along the first portion 33 a of the first groove 33.

  Due to the movement of the boss 44 along the first portion 33a, the shutter lever 41 swings downward about the protrusion 5c. When the shutter lever 41 swings downward about the protrusion 5c, the other end portion 42c of the shutter link 42 swings forward about the rotation shaft 45. At this time, the gear portion 42b of the shutter link 42 meshes with the gear portion 54 (see FIG. 5) of the outer cover 4, and the gear portion 42b moves along the gear portion 54 and the other end portion 42c swings forward. .

  When the other end portion 42 c of the shutter link 42 swings forward, the boss 43 b of the shutter rack 43 moves forward along the groove 51 of the outer cover 4, and the boss 43 c of the shutter rack 43 moves to the groove 52 of the outer cover 4. It moves forward along the (second portion 52b). As a result, the shutter rack 43 moves forward.

  As the shutter rack 43 moves forward, the boss 2 e inserted through the first straight portion 46 a of the through hole 46 moves rearward relative to the shutter rack 43. The boss 2e relatively moved rearward comes into contact with the second linear portion 46b. Thereafter, the boss 2e relatively moves obliquely downward along the second linear portion 46b.

  As described above, when the boss 2e moves relative to the shutter rack 43 obliquely downward, the boss 2e is pressed obliquely from above by the upper wall surface of the second linear portion 46b, so that the boss 2e becomes the second linear portion. It slides along 46 b and moves downward along the first portion 52 a of the groove 52. When the boss 2e moves downward along the first portion 52a, the lid 2 moves downward with respect to the opening D1. By the downward movement of the lid portion 2, the lid portion 2 is lowered below the thickness of the dashboard D. When the boss 2e reaches the lower end of the first portion 52a, the boss 2e reaches the third linear portion 46c.

  Thereafter, as shown in FIG. 12, the boss 43 b of the shutter rack 43 moves forward and obliquely downward along the groove 51, and the boss 43 c of the shutter rack 43 moves forward along the second portion 52 b of the groove 52. And it moves diagonally downward. When the shutter rack 43 moves forward and obliquely downward, the boss 2e that engages with the through hole 46 moves forward and obliquely downward along the second portion 52b of the groove 52, and the boss 2f of the lid portion 2 becomes the groove 53. Move forward along. The boss 2e located at the front end of the lid 2 moves forward and obliquely downward, and the boss 2f located at the rear end of the lid 2 moves forward, so that the lid 2 moves forward and obliquely downward. . And the cover part 2 opens under the dashboard D, and opens the opening D1.

  When the lid 2 opens the opening D1, the boss 67 of the display drive lever 61 moves along the first portion 34a on the second surface 32 of the main gear 30 as shown in FIG. Further, the boss 66b of the tilt lever 66 moves along the fourth portion 34d. As described above, both the first portion 34 a and the fourth portion 34 d extend concentrically with the outer periphery of the main gear 30. Therefore, the boss 67 and the boss 66 b only move along the outer periphery of the main gear 30 and do not move in the radial direction of the main gear 30. Therefore, when the lid 2 opens the opening D1, the display drive lever 61 and the tilt lever 66 do not swing even when the main gear 30 rotates, and the display drive member 60 is in an idling state.

  On the other hand, as shown in FIGS. 13 and 14, as the boss 44 moves along the first portion 33a on the first surface 31 of the main gear 30, the boss 2e, the boss 43b, and the boss 43c are lowered obliquely downward. The boss 2f moves forward. The boss 44 reaches the second portion 33 b of the first groove 33.

  The second portion 33 b of the first groove 33 extends concentrically with the outer periphery of the main gear 30. Therefore, when the boss 44 moves along the second portion 33b, the shutter lever 41 and the shutter link 42 do not swing even if the main gear 30 rotates. Accordingly, the lid driving member 40 is in an idling state. Further, the movement of the boss 44 along the second portion 33b suppresses the swinging of the shutter lever 41 and the shutter link 42. Therefore, it is possible to stably maintain the state in which the lid portion 2 opens the opening D1.

  As described above, the lid driving member 40 is in an idling state, and the opening of the opening D1 by the lid portion 2 is completed. The main gear 30 rotates by an angle of 70 ° or more and less than 200 ° from the start of opening of the opening D1 until the opening of the opening D1 is completed.

(Upward movement of combiner 3)
As described above, after opening the opening D1 in the lid portion 2, the combiner 3 starts to move upward. When the rotation in one direction of the main gear 30 is continued with the reference point P positioned on the front side of the main gear 30, the reference point P moves from the front side of the main gear 30 to the upper side. 14 and 15, the boss 67 of the display drive lever 61 moves from the first portion 34a to the second portion 34b. The second portion 34 b is a portion that extends outward in the radial direction of the main gear 30. For this reason, when the main gear 30 rotates, the boss 67 moves along the second portion 34b, whereby the display drive lever 61 starts to rotate upward about the protrusion 5d of the inner cover 5.

  That is, when the main gear 30 continues to rotate in one direction and the reference point P moves to the upper side of the main gear 30, the display drive lever 61 rotates to move the boss 67 upward about the protrusion 5d. When the display drive lever 61 rotates in this way, the display drive link 62 connected to the display drive lever 61 via the rotation shaft portion 68 rotates upward about the rotation shaft portion 68. At this time, the display drive link 62 is rotated along the gear portion 5g, with the gear portion 70 provided at one end portion 62a thereof meshing with the gear portion 5g (see FIG. 10) of the inner cover 5. Then, the other end 62b of the display drive link 62 moves upward.

  When the other end portion 62 b of the display drive link 62 moves upward, the boss 63 a that has entered the elongated hole portion 71 of the other end portion 62 b moves along the elongated hole portion 71. The boss 63 a that has entered the elongated hole portion 71 is fitted in the groove portion 5 h of the inner cover 5. Therefore, when the other end 62b moves upward, the boss 63a moves upward along the groove 5h. As a result, the tilt link 63 moves upward along the groove 5h.

  When the tilt link 63 moves upward, the carriage 64 that is rotatably connected to the tilt link 63 also moves up. Since the boss 64 b of the carriage 64 is fitted in the groove 5 h of the inner cover 5, the carriage 64 rises along the groove 5 h together with the tilt link 63. At this time, since the holding portion 63b including the tilting axis of the carriage 64 rises linearly along the groove portion 5h, the combiner 3 supported by the carriage 64 rises while maintaining the orientation of the display surface 3a.

  Here, “rising while maintaining the orientation of the display surface 3a” indicates that the combiner 3 rises without changing the orientation of the display surface 3a, that is, the direction in which the display surface 3a faces. Further, “the state in which the orientation of the display surface 3a is maintained” includes a state in which the orientation of the display surface 3a is slightly changed (for example, a state in which the angle of the display surface 3a facing in the oblique direction or the horizontal direction is finely adjusted). Can be.

  As shown in FIGS. 16 and 17, when the main gear 30 continues to rotate in one direction, the reference point P moves from the upper side to the rear side of the main gear 30 and the combiner 3 continues to rise. . When the boss 67 of the display drive lever 61 reaches the third portion 34c of the second groove 34 on the second surface 32 of the main gear 30, the combiner 3 reaches above the opening D1.

  As described above, the third portion 34 c of the second groove 34 extends concentrically with the outer periphery of the main gear 30. For this reason, even if the main gear 30 rotates and the boss 67 moves along the third portion 34c, the display drive lever 61 does not swing. Therefore, thereafter, the display drive lever 61 does not swing, and the rise of the combiner 3 is completed. The main gear 30 rotates by an angle of 70 ° or more and less than 200 ° from the start of the combiner 3 to the completion of the rise of the combiner 3.

(Tilt of combiner 3)
After the combiner 3 completes the rise as described above, the combiner 3 starts to tilt. As shown in FIGS. 17 and 18, when the main gear 30 continues to rotate in one direction after the boss 67 of the display drive lever 61 reaches the third portion 34 c of the second groove 34, the boss 66 b of the tilt lever 66. Reaches the fifth portion 34e from the fourth portion 34d of the second groove 34. When the main gear 30 continues to rotate, the boss 66b moves from the fifth portion 34e to the sixth portion 34f, and then moves along the sixth portion 34f.

  The fifth portion 34 e and the sixth portion 34 f of the second groove 34 are portions that extend outward in the radial direction of the main gear 30. Therefore, when the boss 66b moves along the fifth portion 34e and the sixth portion 34f, the other end portion 66c of the tilt lever 66 swings forward about the shaft hole 66k (see FIG. 8). Further, the boss 66 b is inserted through the through hole 69, but moves without being in contact with the display drive lever 61.

  As described above, when the other end portion 66 c of the tilt lever 66 swings forward, the other end portion 66 c comes into contact with the carriage 64. Then, the boss 64c of the carriage 64 enters the groove 66d of the tilt lever 66, and the boss 64c slides along the groove 66d. At this time, since the groove 66d extends in a direction inclined with respect to the direction in which the tilt lever 66 swings, the boss 64c slides in the groove 66d and the carriage 64 is pressed upward.

  Thus, when the carriage 64 is pressed upward, the combiner 3 supported by the carriage 64 tilts forward together with the carriage 64 about the boss 64b as a rotation axis. The amounts of tilt of the combiner 3 and the carriage 64 are adjusted as appropriate by the operation of the user of the display device 1. Specifically, the position of the boss 66b in the sixth portion 34f of the second groove 34 is adjusted by the user's operation, thereby adjusting the swing amount of the tilt lever 66 and the degree of penetration of the boss 64c into the groove 66d. Thus, the amount of tilt of the combiner 3 is adjusted. Thus, when the combiner 3 tilts forward by a predetermined amount, the main gear 30 stops rotating in one direction, and the tilt of the combiner 3 is completed.

  When the tilt of the combiner 3 is completed, the reference point P is located on the rear side of the main gear 30. Therefore, the main gear 30 does not make one rotation between the time of closing the opening D1 shown in FIG. 11 and the time of tilting of the combiner 3 shown in FIG. That is, while the main gear 30 makes one rotation, a series of operations from opening of the opening D1 by the lid portion 2 to tilting of the combiner 3 is performed. Specifically, the main gear 30 rotates by 240 ° or more and less than 360 ° between the opening of the opening D1 by the lid 2 and the tilting of the combiner 3.

  Next, the operation of accommodating the combiner 3 below the opening D1 and closing the opening D1 with the lid 2 will be described. In this operation, each component moves in the reverse direction and in the reverse order to the series of operations shown in FIGS. That is, the tilting of the combiner 3, the lowering of the combiner 3, and the closing of the opening D1 are performed in this order in series. First, the main gear 30 rotates in the other direction by the driving force of the driving unit 10. The other direction indicates, for example, a direction opposite to the above-described one direction (counterclockwise in FIG. 18).

(Tilt of combiner 3)
As shown in FIGS. 17 and 18, when the main gear 30 rotates in the other direction, the tilt lever 66 swings backward with respect to the carriage 64, and the combiner 3 and the carriage 64 tilt by the urging force of the spring member 65. Is restored. Further, the boss 64c of the carriage 64 comes out of the groove 66d. Then, the boss 66b of the tilt lever 66 moves from the sixth portion 34f to the fourth portion 34d via the fifth portion 34e. Thereby, the tilting state of the carriage 64 and the combiner 3 is restored.

(Combiner 3 descending)
As shown in FIGS. 14 to 16, when the main gear 30 continues to rotate in the other direction, the boss 67 of the display drive lever 61 moves from the third portion 34c to the second portion 34b. Then, the display drive lever 61 swings to move the boss 67 downward, and the display drive link 62 swings to move the other end 62b downward. Further, the boss 63a of the tilt link 63 and the boss 64b of the carriage 64 are lowered along the groove portion 5h of the inner cover 5, whereby the tilt link 63 and the carriage 64 are lowered. At this time, the combiner 3 descends while maintaining the orientation of the display surface 3a.

  Here, “lowering while maintaining the orientation of the display surface 3a” indicates that the combiner 3 is lowered without changing the orientation of the display surface 3a. In addition, “lowering while maintaining the orientation of the display surface 3a” may include a case where the orientation of the display surface 3a is finely adjusted and the combiner 3 is lowered. In the present embodiment, an example in which the combiner 3 moves up and down with the display surface 3a facing obliquely downward is shown, but the direction of the display surface 3a is not limited to the above example. For example, the combiner 3 may move up and down with the display surface 3a facing the horizontal direction.

  Further, when the rotation of the main gear 30 in the other direction is continued, the reference point P moves from the upper side to the front side of the main gear 30, and the boss 67 of the display drive lever 61 is moved to the first portion 34a on the second surface 32 of the main gear 30. To reach. At this time, the lowering of the combiner 3 ends.

(Blockage of opening D1)
When the lowering of the combiner 3 is completed and the rotation of the main gear 30 in the other direction is further continued, the boss 44 is formed on the first surface 31 of the first groove 33 as shown in FIGS. 13 and 14. 1 part 33a enters. And the cover part 2 and the shutter rack 43 move diagonally upward. At this time, the shutter lever 41 and the shutter link 42 swing upward, and as shown in FIGS. 11 and 12, the opening D1 is closed by the lid portion 2 that moves upward.

  Next, effects obtained from the display device 1 according to the present embodiment will be described.

  The display device 1 includes a lid driving member 40 that moves the lid 2 by driving the driving unit 10, a combiner 3 having a display surface 3 a that displays predetermined information, and an opening of the dashboard D by driving the driving unit 10. And a display driving member 60 that moves the combiner 3 up and down while maintaining the orientation of the display surface 3a with respect to D1, and tilts the combiner 3 above the opening D1.

  Thus, in the display device 1, the combiner 3 moves up and down while maintaining the orientation of the display surface 3a, and the combiner 3 tilts above the opening D1. That is, in the display device 1, the combiner 3 does not swing during vertical movement, and the combiner 3 is tilted in a state where the combiner 3 reaches the upper side of the opening D <b> 1. Therefore, since it is not necessary to secure a space for swinging the combiner 3 in the dashboard D, the display device 1 can be arranged in a more limited space. Therefore, the display device 1 can increase the degree of freedom of arrangement.

  Further, the display device 1 includes a main gear 30 that rotates by driving of the driving unit 10. By the rotation of the main gear 30 in one direction, the lid driving member 40 opens the opening D1 in the lid portion 2, and the display driving member 60 moves the combiner 3 upward and tilts the combiner 3. By rotation of the main gear 30 in the other direction, the display driving member 60 tilts the combiner 3 and moves the combiner 3 downward, and the lid driving member 40 closes the opening D1 in the lid portion 2.

  Thus, in the display device 1, the opening D <b> 1 is opened, the combiner 3 is moved upward, and the combiner 3 is tilted by rotating the main gear 30 in one direction, and the combiner 3 is rotated by rotating the main gear 30 in the other direction. Tilting (returning tilting), moving the combiner 3 downward, and closing the opening D1. Therefore, a series of operations such as opening / closing the opening D1, raising / lowering the combiner 3, and tilting the combiner 3 can be performed only by rotating the main gear 30. Therefore, since the number of parts of the display device 1 can be reduced, the dimensions of the display device 1 as a whole in the depth direction (front-rear direction) and the height direction (up-down direction) can be reduced. Therefore, the display device 1 can be reduced in size.

  In the display device 1, opening / closing of the opening D <b> 1, raising / lowering of the combiner 3, and tilting of the combiner 3 are performed by rotation of one main gear 30 provided on each of the left and right sides. The opening / closing of the opening D1, the raising / lowering of the combiner 3, and the tilting of the combiner 3 are executed in this order in series. Therefore, any one of the step of opening and closing the opening D1, the step of raising and lowering the combiner 3, and the step of tilting the combiner 3 can be prevented from interfering with other steps. Therefore, even if a disturbance or an external load acts on the display device 1, it is possible to make it difficult for the display device 1 as a whole to malfunction. That is, the tolerance of the display device 1 against disturbance or the like can be increased.

  Further, in the display device 1, while the main gear 30 makes one rotation in one direction, the lid driving member 40 opens the opening D 1 in the lid portion 2, and the display driving member 60 moves upward of the combiner 3 and the combiner 3. Tilt. Then, while the main gear 30 makes one rotation in the other direction, the display driving member 60 tilts the combiner 3 and moves the combiner 3 downward, and the lid driving member 40 closes the opening D1 in the lid 2. In this way, the above-described series of operations can be performed while the main gear 30 makes one rotation.

  In the display device 1, the main gear 30 has a plate-like shape and includes a first surface 31 and a second surface 32 that face each other, and the lid driving member 40 is engaged with the first surface 31. The display driving member 60 is engaged with the second surface 32. As described above, the lid driving member 40 is engaged with the first surface 31 of the main gear 30 and the display driving member 60 is engaged with the second surface 32, so that the lid from one main gear 30 provided on each of the left and right sides. Driving force is transmitted to both the driving member 40 and the display driving member 60. Therefore, both the lid driving member 40 and the display driving member 60 can be controlled by the single main gear 30. In addition, since both surfaces of the main gear 30 can be effectively used as parts for transmitting the driving force, the number of parts required for driving can be reduced, which contributes to downsizing of the display device 1.

  In the display device 1, the main gear 30 includes a first groove 33 provided on the first surface 31 and a second groove 34 provided on the second surface 32. The lid driving member 40 has a boss 44 that engages with the first groove 33, and the display driving member 60 has a boss 67 that engages with the second groove 34. The main gear 30 rotates and moves the boss 44 along the first groove 33 to move the lid portion 2 to the lid driving member 40, and rotates to move the boss 67 along the second groove 34. Thus, the combiner 3 is moved to the display driving member 60. As described above, the display device 1 includes the first groove 33 and the second groove 34 and the bosses 44 and 67, thereby moving the lid portion 2 to the lid driving member 40 and moving the combiner 3 to the display driving member 60. Can be made. Therefore, the mechanism for moving the lid 2 and the combiner 3 can be simplified.

  Further, the lid driving member 40 includes a shutter lever 41 having a boss 44, a shutter link 42 connected to the shutter lever 41, a shutter rack 43 having bosses 43b and 43c and connected to the lid portion 2, and a boss 43b. , 43c, and an outer cover 4 having grooves 51, 52 to be engaged. Then, as the main gear 30 rotates, the bosses 43b and 43c move along the grooves 51 and 52, so that the lid 2 opens and closes the opening D1. Thus, by moving the bosses 43b and 43c along the grooves 51 and 52 provided in the outer cover 4 to open and close the opening D1 in the lid portion 2, a mechanism for opening and closing the opening D1 can be simplified. . In addition, since the outer cover 4 also has a function of guiding the lid portion 2, the outer cover 4 that protects the display device 1 can be used effectively.

  The display driving member 60 includes a display driving lever 61 having a boss 67, a display driving link 62 connected to the display driving lever 61, a tilt link 63 having a boss 63a and connected to the display driving link 62, And an inner cover 5 having a groove portion 5h with which the boss 63a is engaged. Then, the boss 63a moves along the groove 5h by the rotation of the main gear 30, whereby the combiner 3 moves up and down. Therefore, the boss 63a moves along the groove 5h provided in the inner cover 5 and the combiner 3 moves up and down, whereby the mechanism for moving the combiner 3 up and down can be simplified. Further, the inner cover 5 that protects the display device 1 can be effectively used as a moving mechanism of the combiner 3. Furthermore, by moving the boss 63a along the linearly extending groove 5h, it is possible to easily realize a configuration in which the combiner 3 is moved up and down while maintaining the orientation of the display surface 3a.

  The display driving member 60 includes a carriage 64 that supports the combiner 3 and is swingably connected to the tilt link 63, and a tilt lever 66 that is swingably connected to the inner cover 5. Then, the combiner 3 tilts together with the carriage 64 when the carriage 64 comes into contact with the tilt lever 66 and is pressed by the tilt lever 66 in a state where the combiner 3 reaches above the opening D1. Therefore, the combiner 3 tilts when the carriage 64 is pressed by the tilt lever 66 in a state of reaching the upper side of the opening D1. Therefore, the mechanism for tilting the combiner 3 can be simplified.

  The carriage 64 has a boss 64c, and the tilt lever 66 has a groove 66d. The carriage 64 is pressed by the tilt lever 66 with the boss 64c engaged with the groove 66d. As described above, the carriage 64 is pressed while the boss 64c is engaged with the groove 66d, so that the tilting operation of the carriage 64 and the combiner 3 can be stabilized.

  The display driving member 60 is located between the carriage 64 and the tilt link 63 and includes a spring member 65 that urges the carriage 64 in a direction to return the tilt of the carriage 64 and the combiner 3. Since the spring member 65 urges the carriage 64 in a direction to return the tilt of the carriage 64 to the original position, the tilt (return of tilt) of the combiner 3 and the carriage 64 can be performed without rattling.

  Further, in the display device 1, the driving unit 10 generates a driving force by one motor 11. Thus, the display device 1 is driven by one motor 11. Therefore, compared with the case where a plurality of motors are provided, the number of parts can be reduced and the configuration can be simplified, which contributes to further downsizing of the display device 1.

  Moreover, the cover part 2 performs obstruction | occlusion of the opening D1 and opening | release of the opening D1 by moving diagonally. That is, the lid 2 moves without rotating and opens and closes the opening D1. Therefore, in the display device 1, a space for rotating the lid portion 2 can be eliminated. Further, the lid 2 does not protrude above the dashboard D. Therefore, it can avoid that the cover part 2 obstruct | occludes a driver | operator's view.

(Second Embodiment)
Next, a display device 81 according to the second embodiment will be described with reference to FIGS. 19 and 20. The display device 81 is different from the first embodiment in the configuration of the lid portion 82, the main gear 90, and the lid driving member 100. That is, 2nd Embodiment is corresponded to the modification of a cover part, a rotary body, and a cover drive member. In the following description, the description overlapping with the first embodiment is omitted.

  The main gear 90 has a first surface 91 similar to the first surface 31 described above, and the first surface 91 is provided with a first groove 93 with which the lid driving member 100 is engaged. The first groove 93 includes a first portion 93a that extends concentrically with the outer periphery of the main gear 90, a second portion 93b that is inclined radially outward of the main gear 90, and a third portion 93c that extends concentrically with the outer periphery of the main gear 90. Have The first portion 93a, the second portion 93b, and the third portion 93c are continuous with each other.

  The lid driving member 100 includes a small-diameter gear 101 that meshes with the main gear 90, a shutter lever 102 that engages with a first groove 93 of the main gear 90, and a shutter rack 103. The small diameter gear 101 is disposed above and behind the main gear 90. The lid portion 82 includes a gear portion 82a with which the small-diameter gear 101 is engaged, and the shutter rack 103 also includes a similar gear portion 103a.

  The shutter lever 102 includes a first portion 102a extending linearly at a position facing the first surface 91 of the main gear 90, a second portion 102b extending in a direction intersecting the first portion 102a from the first portion 102a, and a second portion 102b. A third portion 102c extending from the end of the portion 102b opposite to the first portion 102a toward the lid portion 82;

  The first portion 102 a includes a boss 105 that engages with the first groove 93, and the lid driving member 100 is engaged with the main gear 90 when the boss 105 enters the first groove 93. A rotating shaft 102d is provided at the end of the first portion 102a opposite to the boss 105. A boss 106 that engages with the lid 82 is provided at the end of the third portion 102c opposite to the second portion 102b. The lid portion 82 includes a boss accommodating portion 82 b that engages the boss 106 with the lid portion 82 by allowing the boss 106 to enter. The boss accommodating portion 82 b is provided at the rear end of the lid portion 82.

  Next, in the display device 81 of the second embodiment, an operation for opening and closing the opening D1 in the lid 82 will be described. When the drive unit 10 is driven in the initial state where the lid portion 82 covers the opening D1, the driving force of the drive unit 10 is transmitted to the main gear 90 via the drive gear 21 as in the first embodiment. With this driving force, the main gear 90 starts to rotate in one direction (for example, clockwise in FIG. 19).

(Opening of the opening D1 by the lid part 82)
When the main gear 90 starts to rotate in one direction, the boss 105 of the shutter lever 102 starts to move along the first portion 93a of the first groove 93. However, since the first portion 93a extends concentrically with the outer periphery of the main gear 90, the shutter lever 102 does not operate when the boss 105 moves along the first portion 93a.

  When the main gear 90 starts to rotate in one direction, the small-diameter gear 101 that meshes with the main gear 90 rotates in the other direction (for example, counterclockwise in FIG. 19). When the small-diameter gear 101 rotates in the other direction, the shutter rack 103 that meshes with the small-diameter gear 101 starts to move forward. As in the first embodiment, the lid 82 moves downward with respect to the opening D1, and then the lid 82 moves forward and obliquely downward. Thus, the opening D1 is opened by the lid 82 moving downward and forward.

  Further, the main gear 90 rotates in one direction to open the opening D1, and the boss 105 of the shutter lever 102 reaches the second portion 93b of the first groove 93 immediately before the opening operation is completed. As shown in FIG. 21, when the boss 105 moves along the second portion 93b, the third portion 102c of the shutter lever 102 swings upward about the rotation shaft 102d.

  Further, as the lid portion 82 moves forward, the boss accommodating portion 82b approaches the boss 106 from the rear, and the boss 106 is engaged with the boss accommodating portion 82b. Then, the lid portion 82 is lifted upward by the engagement of the boss 106 with the boss accommodating portion 82b and the upward swing of the third portion 102c. At this time, the engagement of the gear portion 82a with the small-diameter gear 101 is released. After the meshing of the gear portion 82a is released, the opening of the opening D1 by the lid portion 82 is completed. Thereafter, as in the first embodiment, the combiner 3 is lifted and the combiner 3 is tilted.

(Closing the opening D1 by the lid part 82)
In the operation of closing the opening D1 in the lid portion 82, each component operates in the reverse direction and the reverse order to the operation of opening the opening D1 in the lid portion 82. That is, when the main gear 90 rotates in the other direction in the state shown in FIG. 21, the boss 105 moves inward in the radial direction of the main gear 90 along the second portion 93b, and accordingly, the third portion 102c of the shutter lever 102 is moved. Swings downward. When the third portion 102c swings downward, the engagement of the boss 106 with the boss accommodating portion 82b is released, and the gear portion 82a meshes with the small diameter gear 101. Then, the lid 82 and the shutter rack 103 move rearward and obliquely upward, and the lid 82 closes the opening D1.

  As described above, in the display device 81 according to the second embodiment, the configurations of the lid portion 82, the main gear 90, and the lid driving member 100 are different from those of the first embodiment, and the combiner 3 is moved up and down while maintaining the orientation of the display surface 3 a. The moving point is common to the first embodiment. Therefore, the display device 81 can obtain the same effect as that of the first embodiment.
