  Examples of the present invention will be described in detail below.

  FIG. 1 is a perspective view of a display device 10 according to an embodiment of the present invention. FIG. 1 shows a display device 10 during a display operation (hereinafter simply referred to as an operation). For example, the display device 10 is a head-up display. The casing 11 of the display device 10 includes a top plate TP. The top plate TP has two openings 12 and 12a formed separately. Furthermore, the display device 10 includes a combiner unit 13 that is a display member that can be moved up and down through the opening 12. In this specification, a direction in which an observer (not shown) views the front of the combiner unit 13 is referred to as a depth direction (x-axis direction). Moreover, the back side direction means the arrow direction of the x axis in the drawing. The horizontal direction orthogonal to the x-axis direction is referred to as the width direction (y-axis direction) of the housing 11. A direction orthogonal to both the depth direction and the width direction of the housing 11 is referred to as a height direction (z-axis direction) of the housing 11. Moreover, the use position of the user of the combiner unit 13 during the operation of the display device 10 as shown in FIG.

  The display device 10 is mounted in a dashboard such as a four-wheeled vehicle. In the present embodiment, the top plate TP has a substantially flat shape or a gentle curved surface shape that can constitute a part of the upper surface on the windshield side of the dashboard. Moreover, the housing | casing 11 contains side plate part SP provided with cover part SPa in the both sides of the width direction of the top plate TP. The side plate portions SP extend in the depth direction of the housing 11 and are provided to face each other in the width direction of the housing 11.

  When the display device 10 is mounted on a dashboard of a vehicle, the display device 10 is disposed on the front side of a windshield (not shown). During operation, a virtual image is formed on the back side of the combiner unit 13 by the irradiation light from the opening 12a. In the present embodiment, the combiner unit 13 is, for example, a plate-like combiner that bulges toward the back side and is slightly curved, and is formed of a translucent member such as a resin member that transmits light such as plastic.

  As shown in FIG. 1, the display device 10 includes a lid member 19 that closes the gap T between the combiner unit 13 and the top plate TP that forms the opening 12 at the unfolded position. In the present embodiment, for example, the lid member 19 is formed of a flat plate member having a light shielding property that closes the gap T. The lid member 19 closes the opening 12 on the back side of the combiner unit 13 and the gap T between the combiner units 13 when the display device 10 operates. For this reason, the lid member 19 can prevent a foreign substance or the like from falling into the gap T in the opening position of the combiner unit 13 (the operation state shown in FIG. 1). Further, the lid member 19 can prevent the sunlight from entering the display device 10 and can prevent deterioration of the members in the display device 10. The lid member 19 opens the opening 12 while the combiner unit 13 is being lifted and lowered. On the other hand, the lid member 19 is accommodated on the back side of the combiner unit 13 when the combiner unit 13 is accommodated in the housing 11.

  The display device 10 is connected to, for example, a detection device (not shown) that detects the position and speed of the vehicle on which it is mounted, the moving direction, the surrounding situation, and the like. For example, the display device 10 is connected to a navigation device (not shown) mounted on the vehicle. For example, during operation, the combiner unit 13 is instructed to provide driving support information based on information input from a detection device, a navigation device, or the like (for example, the speed of the vehicle, the distance from the preceding vehicle, and an instruction to turn left or right at the intersection). Information etc.) is displayed.

  FIG. 2 is a perspective view of the display device 10 before the operation of the display device 10 (hereinafter referred to as non-operation time). Note that the position of the combiner unit 13 when the display device 10 shown in FIG. 2 is not operating is shown in FIGS. 5 and 8, and the position is referred to as an accommodation position. The display device 10 includes a shutter 20 that closes the entire opening 12 when the combiner unit 13 is in the storage position. In the present embodiment, for example, the shutter 20 has a substantially flat plate-shaped portion having a light shielding property that closes the opening 12. The shutter 20 closes the opening 12 when the combiner unit 13 when not operating is accommodated in the housing 11. On the other hand, the shutter 20 is accommodated in the housing 11 during the raising and lowering of the combiner unit 13 and during operation (the state shown in FIG. 1), and opens the opening 12. The shutter 20 can prevent foreign matters from dropping into the display device 10 and intrusion of solar radiation when not in operation, and can prevent deterioration of members in the display device 10.

  Specifically, for example, the combiner unit 13 is accommodated in the housing 11 before the power is turned on (before the vehicle engine is started), and the shutter 20 closes the opening 12. Next, immediately after the power is turned on, the shutter 20 starts to open the opening 12. Next, when it is detected by a sensor or the like that the shutter 20 has completed opening the opening 12, the combiner unit 13 starts to move through the opening 12. After the combiner unit 13 has moved to the unfolded position, the display operation on the combiner unit 13 is started. When the power is turned off, the combiner unit 13 moves to the accommodation position in the housing 11 and the shutter 20 closes the opening 12.

  FIG. 3 is a perspective view, partly cut away, schematically showing the internal structure of the display device 10 during operation. In this embodiment, the shutter 20 is retracted to the near side of the combiner unit 13 during operation. The display device 10 includes a light source 14 and a reflecting member 15 accommodated in the housing 11.

  The light source 14 is located at a position different from the movement path of the shutter 20 (between the retracted position and the closed position) and the movement path of the combiner unit 13 (the lifting path between the storage position and the unfolded position) in the housing 11. In particular, it is provided at a position that does not hinder the movement of the shutter 20 and the raising / lowering of the combiner unit 13. For example, the light source 14 generates irradiation light PL that is incident on the combiner unit 13 based on information input from a detection device or a navigation device. The reflection member 15 reflects the irradiation light PL toward the combiner unit 13. The irradiation light PL passes through the opening 12 a from the front side of the combiner unit 13 and is incident on the irradiated surface of the combiner unit 13. The irradiation light PL incident on the combiner unit 13 forms a virtual image on the back side of the combiner unit 13. In the present embodiment, the opening 12a is provided in a region on the nearer side than the opening 12 in the top plate TP. Note that the opening 12a may be closed with a translucent member (not shown) such as a transparent film.

  As shown in FIG. 3, the irradiation light PL enters the combiner unit 13 through the opening 12a. That is, the opening 12a has a predetermined size and shape through which the irradiation light PL can pass, and forms an optical path of the irradiation light PL to the combiner unit 13. The retracted position of the shutter 20 is set so as not to disturb the optical path of the irradiation light PL.

  Next, the moving mechanism 30 of the combiner unit 13 accommodated in the housing 11 will be described with reference to FIGS. FIG. 4 is a perspective view of the display device 10 schematically showing the relationship between the side plate portion SP and the combiner unit 13. FIG. 5 is a perspective view illustrating the moving mechanism 30 of the combiner unit 13 and the display device 10 in which the combiner unit 13 is in the storage position. In addition, in FIG. 5, the cover part SPa and the top plate TP are shown with the dashed-two dotted line. FIG. 6 is a perspective view of the cover part SPa of the side plate part SP of the display device 10 as viewed from the inside of the housing 11. 7 and 8 are internal views of the display device 10 when the combiner unit 13 is unfolded and housed. 9 to 11 are schematic diagrams for explaining the movement of the combiner unit, the lid member 19 and the shutter 20 in the display device 10 from when the combiner unit 13 is accommodated to when it is deployed.

  First, the combiner unit 13 is demonstrated using FIG.4 and FIG.5.

  As shown in FIG. 4, the combiner unit 13 includes a combiner portion 13 a and a holding portion 13 b that holds the lower end portion thereof. The holding part 13b is a U-shaped member having a first combiner pin 21 at each of a pair of free end parts extending at a predetermined angle along both ends of the combiner part 13a. The holding portion 13b includes a pair of second combiner pins 22 that extend in parallel with the lower end portion of the combiner portion 13a and serve as a rotation shaft of the combiner portion 13a at the deployed position.

  In the present embodiment, each of the first and second combiner pins 21 and 22 is a cylindrical portion or component that is provided in the holding portion 13b and extends in the width direction (y-axis direction) of the housing 11. Further, the pair of first combiner pins 21 are provided so as to be aligned in the width direction of the casing 11, and the pair of second combiner pins 21 are provided so as to be aligned in the width direction of the casing 11. In the holding portion 13b, each combiner pin has a width of the housing 11 such that the central axis CA2 of the pair of second combiner pins 22 and the central axis CA1 of the pair of first combiner pins 21 are parallel to each other. Projecting outward in the direction (y-axis direction).

  When the pair of second combiner pins 22 reaches the deploying position of the combiner unit 13, when the first combiner pin 21 is moved, the combiner unit 13 is rotated about the second combiner pin 22 as a rotation axis. Move. Further, a flange portion 13c is provided on the back side (the lid member 19 side) of the holding portion 13b, and the edge of the lid member 19 that closes the gap T between the combiner unit 13 and the opening portion 12 at the unfolded position shown in FIG. A collar portion 13c is formed so as to cover the portion. As a result, it is possible to further prevent foreign matter and the like from falling into the gap T into the apparatus.

  Further, when the combiner unit 13 at the unfolded position is provided with the angle adjustment function of the combiner unit 13, the flange 13 c covers at least the front edge of the lid member 19 within the angle adjustment range of the combiner unit 13. Further, it may be formed so as to overlap with the lid member 19 in the height direction (z direction). As a result, it is possible to prevent a foreign substance or the like from falling into the display device 10 via the gap T, regardless of where the combiner unit 13 in the deployed position is located within the angle adjustment range.

  As shown in FIGS. 4 and 5, each of the pair of side plate portions SP of the housing 11 facing each other in parallel has a pair of first plates formed in the same shape and having a predetermined trajectory that is inclined and curved in the depth direction. One combiner rail SH1 is provided symmetrically with respect to a plane parallel to the pair of side plate portions SP and intermediate between the side plate portions SP (hereinafter simply referred to as “symmetric”). Further, each of the side plate portions SP has a pair of curved second combiner rails SH2 that are formed in the same shape and are inclined and curved in the same direction apart from the pair of first combiner rails SH1. Are provided symmetrically. The first combiner rail SH1 is formed as a hole so that the first combiner pin 21 of the combiner unit 13 is inserted and penetrated. The second combiner rail SH <b> 2 is formed as a groove in a pair of side plate portions SP facing each other of the housing 11 into which the second combiner pin 22 of the combiner unit 13 is inserted. Since the first and second combiner pins 21 and 22 are inserted into the first and second combiner rails SH1 and SH2, the movement range and movement locus thereof are the same as those of the first and second combiner rails SH1 and SH2. Limited by shape.

  In this embodiment, the first combiner pin 21 moves along the first combiner rail SH1 and the second combiner pin 22 moves along the second combiner rail SH2 at the same time. As the first and second combiner pins 21 and 22 move, the combiner unit 13 is moved between the pair of side plate portions SP by the first and second combiner pins 21 and 22. Move in a trajectory along SH1 and SH2. That is, the combiner unit 13 moves toward or away from the top plate TP of the housing 11 and slides up and down (up and down). In the present embodiment, the second combiner rail SH2 is provided in a substantially arc shape in the side plate portion SP. Accordingly, the combiner unit 13 partially moves in an arcuate path. That is, the combiner unit 13 translates while rotating.

  Next, the moving mechanism 30 of the combiner unit 13 is demonstrated using FIG.5 and FIG.6. The moving mechanism 30 is provided on at least one of the two side plate portions SP facing each other of the housing 11, and moves the combiner unit 13 using the driving force of the driving source 16. In the present embodiment, the moving mechanism 30 is provided on one of the two opposing side plate portions SP. The drive source 16 mounted in the housing 11 includes, for example, an electric motor that generates a driving force. The moving mechanism 30 has a first pinion gear 31 that is rotated by a gear train (not shown) that is rotated by the drive source 16. The driving force is transmitted to the moving mechanism 30 by the rotation of the first pinion gear 31. The moving mechanism 30 moves the combiner unit 13 by the transmitted driving force.

  The moving mechanism 30 includes first and second slide members 32 and 34 that move along the side plate portion SP. Further, the moving mechanism 30 includes a second pinion gear 33 that is a transmission member that transmits the driving force of the first slide member 32 to the second slide member 34.

  Specifically, in the side plate portion SP, grooves of the first and second slide rails SL1 and SL2 extending linearly in parallel with the depth direction (x-axis direction) of the housing 11 are the first and second combiners. The rails SH1 and SH2 are provided so as to intersect. The first and second slide members 32 and 34 have first and second slide pins 32A and 34A that are inserted into the first and second slide rails SL1 and SL2, respectively. A plurality of first and second slide pins 32A and 34A are provided on the first and second slide members 32 and 34, respectively, on a straight line.

  The first slide member 32 has a first rack gear portion 32G that meshes with the first pinion gear 31. The first slide member 32 slides along the first slide rail SL <b> 1 when a driving force is transmitted from the first pinion gear 31 rotated by the drive source 16 via the first rack gear portion 32 </ b> G.

  The second pinion gear 33 that is a transmission member is fixed to the end portion of the first slide member 32. The second pinion gear 33 slides with the first slide member 32.

  As shown in FIG. 6, the side plate portion SP has a third rack gear portion SG that meshes with the second pinion gear 33 in the cover portion SPa. The cover portion SPa is provided with a first slide rail SL1a into which the first slide pin 32A of the first slide member 32 is inserted. The first slide rail SL1a is formed in the same shape in parallel with the first slide rail SL1 on the side plate portion side.

  As shown in FIG. 5, the cover part SPa is fixed in parallel to the main body of the side plate part SP, and defines a space for accommodating the moving mechanism 30 between the cover part SPa and the side plate part SP. The second pinion gear 33 slides with the first slide member 32. Further, since the second pinion gear 33 is engaged with the third rack gear portion SG, the second pinion gear 33 is rotated by the slide of the first slide member 32. In this way, the second pinion gear 33 moves in translation while rotating.

  As shown in FIG. 5, the second slide member 34 has a second rack gear portion 34 </ b> G that meshes with the second pinion gear 33. Therefore, when the second pinion gear 33 rotates, the second slide member 34 slides along the second slide rail SL2. In the present embodiment, the first and second slide members 32 and 34 are slidable in the depth direction (x-axis direction) of the housing 11.

  The second pinion gear 33 doubles the amount of movement of the first slide member 32 and transmits it to the second slide member 34. That is, the second pinion gear 33 moves the second slide member 34 relative to the first slide member 32 and doubles (increases) the amount of movement of the second slide member 34. Specifically, as shown in FIG. 7, the first slide member 32 follows the rotation of the first pinion gear 31, for example, the position P <b> 1 before sliding movement (the rotation axis of the second pinion gear 33. As shown in FIG. 8, the slide movement is performed from the position) to the position Q1 (the position of the rotation axis of the second pinion gear 33). Here, the length from the position P1 where the first slide member 32 moves to the position Q1 is defined as a length L. At this time, as shown in FIG. 7, the second slide member 34 is moved from the position P2 before movement (the position of the end of the second slide member 34) to a length (X ( Slide) to a position Q2 (position of the end of the second slide member 34) separated by (times) × L). Here, the magnification X is a number larger than 1, and includes an integer such as 2 or 3 and a decimal number such as 1.1 or 1.5. In the present embodiment, since the second pinion gear 33 rotates between the first rack gear portion 32G and the third rack gear portion SG having the same tooth pitch, X = 2 and the second pinion gear 33 Moves the second slide member 34 by a movement amount obtained by doubling (2L) the movement amount of the first slide member 32. If the second pinion gear 33 is a two-stage gear, the amount of movement of the second slide member 34 that meshes in the direction with the larger number of teeth with respect to the first slide member 32 that meshes in the direction with the smaller number of teeth further increases. It can also be increased.

  In the present embodiment, the second pinion gear 33 moves the second slide member 34 by a movement amount obtained by doubling the movement amount of the first slide member 32. Further, both the first slide member 32 and the second slide member 34 simultaneously move relative to the side plate portion SP and move so as to approach or move away from each other.

  As shown in FIGS. 5, 7, and 8, the second slide member 34 has a guide hole 34 </ b> H into which the first combiner pin 21 of the combiner unit 13 is inserted at one end thereof. In the present embodiment, the guide hole 34H is an elongated hole extending linearly at right angles to the extending direction of the tooth row of the second rack gear portion 34G of the second slide member 34 (moving direction of the second slide member 34), That is, the second slide member 34 is formed as a long hole extending in the height direction (z-axis direction) of the housing 11. The first combiner pin 21 is inserted (hooked) into both the first combiner rail SH1 and the guide hole 34H. When the second slide member 34 slides, the first combiner pin 21 is pushed by the inner wall surface of the guide hole 34H of the second slide member 34 and moved along the first combiner rail SH1. That is, the combiner unit 13 moves according to the movement of the second slide member 34.

  Specifically, the combiner unit 13 shown in FIG. 7 moves so that the first slide member 32 and the second slide member 34 move away from each other from the substantially vertical position of the deployed position, and is shown in FIG. It reaches the accommodation position. Conversely, if the first slide member 32 and the second slide member 34 move so as to approach each other, the combiner unit 13 at the storage position shown in FIG. 8 moves from the storage position and reaches the deployed position.

  Next, the opening / closing operation of the lid member 19 and the shutter 20 accompanying the raising / lowering operation of the combiner unit 13 will be described with reference to FIGS. 5 and 7 to 11.

  The lid member 19 is a U-shaped member including a lid flat plate portion 19p which is a flat plate portion having light shielding properties and a pair of first arm portions 19s extending from both ends of the lid flat plate portion 19p. The first arm portion 19s has a rotation pin 19a at its free end. The lid member 19 has a driven pin 19b on its arm 19s (moving mechanism 30 side). The lid member 19 has a rotation pin 19a rotatably provided on the side plate portion SP so that the lid flat plate portion 19p is in a position to close the opening 12 at the deployment position of the combiner unit 13 and the gap T between the combiner units 13. ing. The lid member 19 is disposed so that the rotation axis (center axis CA) of the second combiner pin 22 of the combiner unit 13 and the center axis of the pair of rotation pins 19a are parallel to each other. In the side plate portion SP, a cover rail SH5 through which the driven pin 19b passes is formed in a circular arc shape convex toward the back side around the rotation pin 19a. That is, when the driven pin 19b is positioned at the lower end of the arc-shaped lid rail SH5, the lid member 19 is at the retracted position, and when the driven pin 19b is positioned at the upper end of the arc-shaped lid rail SH5, the lid member 19 is at the closed position. Thus, the lid member 19 and the lid rail SH5 are formed. The lower end of the arc-shaped lid rail SH5 is disposed at a position that does not intersect the trajectory of the first slide member 32 between the first and second combiner rails SH1 and SH2.

  The second slide member 34 has a cam portion 34 </ b> B that drives the driven pin 19 b of the lid member 19. The cam portion 34B is formed at the other end portion opposite to the one end portion of the guide hole 34H of the second slide member 34, and an inclined surface is provided on the upper end surface. The inclined surface at the upper end surface of the cam portion 34B protrudes from the lower end of the arc-shaped lid rail SH5 at the retracted position of the lid member 19 when the first and second slide members 32, 34 move so as to approach each other. The driven pin 19b is formed so as to be gradually pushed up to the closing position of the lid member 19 at the upper end of the lid rail SH5.

  The shutter 20 is a U-shaped member including a shutter flat plate portion 20p that is a flat plate portion having light shielding properties and a pair of second arm portions 20s extending from both ends of the shutter flat plate portion 20p. Further, the second arm portion 20s has a pair of sliding pins 20a at the free end portion and the root portion, respectively. The two pairs of sliding pins 20a of the free end portion and the root portion of the second arm portion 20s of the shutter 20 are arranged so that the respective central axes are parallel to each other. Each pair of sliding pins 20a faces each other. The shutter 20 has a linear guide hole 20H in the middle of the second arm portion 20s (on the moving mechanism 30 side).

  In each of the opposing side plate portions SP, linear or curved shutter rails SH3 and SH4 that respectively guide the pair of sliding pins 20a are formed symmetrically. The shutter rails SH3 and SH4 are configured such that when the light-shielding flat plate-shaped portion 20p of the shutter 20 is mounted on the side plate portion SP, the inserted slide pin 20a is slidable obliquely on the front side. It is arranged to be. That is, when the sliding pin 20a is positioned at each lower end of the shutter rails SH3 and SH4, the shutter 20 is in the retracted position, and when the sliding pin 20a is positioned at each upper end of the shutter rails SH3 and SH4, the shutter 20 is in the closed position. In addition, shutter rails SH3 and SH4 are formed. Notch portions SPc corresponding to the retracted positions of the shutters 20 are formed symmetrically at the upper ends of the side plate portions SP near the upper ends of the shutter rails SH3 and SH4. The shutter 20 is disposed at a position that does not intersect the optical path of the light source 14 at the retracted position.

  A driving lever 26 that moves the shutter 20 through the guide hole 20H of the shutter 20 is provided on the side plate SP on the moving mechanism 30 side. The drive lever 26 has a drive pin 26a inserted into the guide hole 20H at one end, a support pin 26b to the side plate portion SP of the drive lever 26, and a follower portion 26c at the other end.

  As shown in FIG. 7, the second slide member 34 is provided with a cam portion 34C having an inclined surface 34C1 and an upper end flat surface 34C2 for driving the follower portion 26c of the drive lever 26. The inclined surface 34C1 of the cam portion 34C extends at an angle with respect to the moving direction of the second slide member 34. In the present embodiment, as an example, the inclined surface 34C1 of the cam portion 34C extends in a direction (z direction) perpendicular to the moving direction of the second slide member 34. The upper end plane 34C2 of the cam portion 34C extends in a direction (x direction) parallel to the moving direction of the second slide member 34.

  Next, referring to FIG. 9, when the follower portion 26c and the inclined surface 34C1 of the cam portion 34C are engaged, the second slide member 34 moves to cause the drive lever 26 to pivot on the support pin 26b. Rotate as Further, when the follower portion 26c and the upper end flat surface 34C2 of the cam portion 34C are engaged, the drive lever 26 does not rotate even if the second slide member 34 moves. Thus, the cam portion 34C of the second slide member 34 moves the shutter 20 to the retracted position and holds it in the retracted position when the first and second slide members 32 and 34 move closer to each other. It is formed to make it.

  As shown in FIG. 9, when not in operation, the combiner unit 13 is tilted and stored in the storage position. The combiner unit 13 is covered by the shutter 20, and the entire opening 12 (FIG. 2) is closed by the shutter 20. When the power source is connected to the display device 10, the motor 16 as a driving source is turned on, the moving mechanism 30 is driven, the first pinion gear 31 is rotated, and the first slide member 32 is moved in the depth direction (drawing). To the left).

  Here, the second pinion gear 33 moves together with the first slide member 32, the second pinion gear 33 rotates on the third rack gear portion SG, and the driving force is transmitted to the second slide member 34. To do. Therefore, when the second slide member 34 starts to move in the depth direction (left direction in the drawing), the cam portion 34C of the second slide member 34 pushes the follower portion 26c of the drive lever 26, thereby supporting the drive lever 26 as a support pin. The drive pin 26a of the drive lever 26 is moved toward the front side in the depth direction (right direction in the drawing). Therefore, the drive pin 26a moves the shutter 20 to the near side in the depth direction (right direction in the drawing) through the guide hole 20H of the shutter 20.

  FIG. 10 is a perspective view of the display device 10 in a state in the middle of the transition between the accommodation position of the combiner unit 13 and the deployed position. As shown in FIG. 10, when the second slide member 34 moves, the follower portion 26 c of the drive lever 26 slides on the upper end plane of the cam portion 34 </ b> C of the second slide member 34. Thereby, the shutter 20 is held at the retracted position.

  Further, the cam portion 34 </ b> B of the second slide member 34 moves and hits the driven pin 19 b of the lid member 19. Thereafter, the cam portion 34B drives the driven pin 19b along the arc-shaped lid rail SH5 to rotate the lid member 19 around the rotation pin 19a. The cam portion 34B slides the driven pin 19b on the inclined surface at the upper end of the cam portion 34B and gradually pushes it up to the closing position of the lid member 19 at the upper end of the lid rail SH5. In this state, the opening 12 (FIG. 2) is partially opened.

  FIG. 11 is a perspective view of the display device 10 in a state where the combiner unit 13 is deployed. As shown in FIG. 11, the lid member 19 closes the opening 12 (FIG. 1) on the back side of the combiner unit 13 and the gap T between the combiner units 13 at the unfolded position.

  The drive lever 26 is urged counterclockwise (counterclockwise) on a rotation axis perpendicular to the paper surface of the support pin 26b in FIG. Therefore, when the second slide member 34 starts to move forward (rightward in the figure) from the state shown in FIG. 11, the shutter 20 is engaged while the follower portion 26c and the upper end flat surface 34C2 of the cam portion 34C are engaged. Is held in the retracted position. When the second slide member 34 further moves forward, the follower portion 26c engages or comes into contact with the inclined surface 34C1 of the cam portion 34C, and the drive lever 26 is urged counterclockwise (counterclockwise) in the figure. By the urging force applied, the support pin 26b is rotated counterclockwise. As a result, the shutter 20 moves to the closed position and is held at the closed position.

  As described above, in the present embodiment, the first and second slide members 32 and 34, and the transmission member 33 that doubles the amount of movement of the first slide member 32 and transmits it to the second slide member 34. , A relatively large amount of movement (stroke) to the second slide member 34 can be generated. Therefore, the lid member 19, the shutter 20, and the combiner unit 13 can be moved within a space-saving manner.

  In this embodiment, the case where the moving mechanism 30 that drives the lid member 19, the shutter 20, and the combiner unit 13 is configured by combining the rack mechanism and the pinion mechanism has been described. However, the moving mechanism 30 is not limited thereto. . Moreover, although the case where the moving mechanism 30 consists of the 1st and 2nd slide members 32 and 34 and the 2nd pinion gear 33 (transmission member) was demonstrated, the structure of the moving mechanism 30 is not limited to this. For example, an intermediate slide member is provided between the first and second slide members 32 and 34, and a pinion gear is provided between them, whereby the amount of movement can be doubled in three stages.

  Moreover, although the case where the cover member 19 was rotated was demonstrated, the movement form of the cover member 19 is not limited to this. In the present embodiment, the moving mechanism 30 doubles the amount of movement of the first and second slide members 32 and 34 and the first slide member 32 and transmits the transmission member 33 to the second slide member 34. The case of having a doubling mechanism has been described. However, the moving mechanism 30 is not limited to the case of having a doubling mechanism. The moving mechanism 30 has a slide member that moves along the side plate portion SP, and the combiner unit 13 and the lid member 19 may be configured to move according to the movement of the slide member. For example, the slide member corresponds to the second slide member 34. In this case, for example, the first pinion gear 31 only needs to mesh with the second rack gear portion 34G of the second slide member 34.
