Description

  The present invention relates to a display system. Specifically, the present invention relates to a display system in a head-up display (HUD) device, for example.

  Conventionally, one type of head-up display includes a combiner that is different from the windshield and a display. This is because a display device (combiner) composed of a half mirror or the like is arranged on the upper surface of the instrument panel (dashboard), and this combiner located on the driver side of the windshield has a liquid crystal display or the like. A virtual image is displayed by a combiner by projecting light from a display.

  The combiner should be housed when not in use. As such a head-up display, a so-called pop-up type is disclosed in which the combiner is tilted when housed and the combiner is raised so that an image is displayed on the combiner when used (see Patent Document 1).

  In this combiner system, when the shutter is closed, the combiner is housed in the case in a collapsed state. When the shutter is opened, the combiner rises from the opening and protrudes. When the combiner pops up, an opening having a large area is formed. Therefore, a shutter (cover) that opens and closes the opening is provided on the upper surface of the combiner system for storing the combiner, for aesthetic reasons and dust countermeasures.

Japanese Patent Laid-Open No. 11-91403

  The pop-up combiner stands up to a position where the combiner that is housed in the combiner system when it is housed can easily see the display. In the method in which the combiner is turned up from the storage position to the use position, an opening having an area larger than the area of the combiner is required, and a shutter (cover) that covers the opening is required. However, the driving mechanism for driving the shutter having a larger area than the combiner becomes large, which causes an increase in size and cost of the apparatus.

  To reduce the size of the opening, the combiner can be moved vertically, but the downward protruding distance increases and there is no room in the dashboard where the air conditioner or other duct runs. It is desirable to place it horizontally.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a combiner system that can be erected vertically during use and can be erected vertically during use, and that the shutter that shields the opening during storage is small and the entire apparatus is low in cost.

  In order to solve the above-described problems and achieve the object, the display system of the present invention according to claim 1 is configured such that a display device for displaying an image has a use position and a storage position different from each other, and an opening portion thereof. First and second shutters having a width larger than the width of the display device, and when the display device is in the use position, at least a part of the display device is the first and second shutters. It is located above the shutter, and at least one of the first and second shutters is closed.

It is a mimetic diagram showing a head up display carrying a combiner system (display system) concerning an example of the present invention. It is a schematic diagram for demonstrating the combiner and pop-up mechanism in the combiner system which concerns on the Example of this invention. It is a front view of the guide member in the combiner system concerning the example of the present invention. In the combiner system which concerns on the Example of this invention, it is the schematic which shows the locus | trajectory of a combiner when a combiner moves from an accommodation position to a use position. It is the schematic perspective view which extracted and extracted only the shutter mechanism (opening-closing shutter) and its peripheral member from the combiner system which concerns on the Example of this invention. In the combiner system which concerns on the Example of this invention, it is a schematic explanatory drawing which shows the motion of the shutter mechanism at the time of a process at the time of a combiner moving between an accommodation position and a use position for every process. In the combiner system which concerns on the Example of this invention, it is a top view which shows the example of the open / close state of a shutter mechanism.

  Hereinafter, a display system (combiner system) according to an embodiment of the present invention will be described. A display system according to an embodiment of the present invention is configured such that a display device that displays an image has a use position and a storage position different from each other. Since it moves to the position which cannot be seen from a user at the time of accommodation, it is preferable on beauty. In addition, a display system according to an embodiment of the present invention includes first and second shutters in which an opening width between a use position and a storage position is larger than a width of the display device, and the display device Is in the use position, at least a part of the display device is located above the first and second shutters, and at least one of the first or second shutters is closed. Therefore, when the display device is used, an unnecessary opening is narrowed, which is preferable in terms of aesthetics and dust countermeasures.

  In the first and second shutters, the opening of the first shutter and the opening of the second shutter are continuous openings. Can be narrowed.

  In addition, when the display device is in the use position, the second shutter is in an open state, and a part of the display device is located in the opening of the second shutter, so that the opening is controlled. Can be done flexibly.

  In addition, when the display device is in the use position, the display device is erected in a substantially vertical state, so that it is easy for the user to use.

  When the display device is in the use position, the first shutter is in the closed state, so that unnecessary openings can be blocked in the use state.

  In addition, when the display device is in the use position, the opening and closing directions of the first and second shutters and the standing direction of the display device are substantially perpendicular to each other, so that it is possible to secure an opening necessary for moving the display device. This can be achieved with less shutter movement.

  When the display device is in the storage position, the first and second shutters are in the closed state, which is preferable in terms of aesthetics and dust countermeasures.

  In addition, when the display device is in the storage position, the display device is located below the first shutter and the second shutter in the previous period, so that the display device does not obstruct the field of view when the display system is not used. .

  In addition, when the display device is in the storage position, the display device is stored in a substantially horizontal direction, so that the display device can be mounted in a narrow space in the downward direction.

  Further, when the display device moves from the housed position to the use position, the first shutter is opened before the second shutter, so that a space necessary for moving the display device is secured. There is no waste.

  In addition, when the display device moves from the use position to the accommodation position, the second shutter is closed before the first shutter, so that it is useless to secure a space necessary for moving the display device. Does not occur.

  In addition, since at least one of the first shutter and the second shutter is opened and closed by rotating about a predetermined axis, it is easy to drive the shutter.

  In addition, the display device is a combiner that reflects light projected on the viewing side surface to the user side, thereby projecting an image drawn by the light onto the user's field of view. You can see a virtual image.

  Further, the display device is a combiner that reflects the light projected on the surface on the viewing side toward the driver's seat, thereby projecting the image drawn by the light onto the field of view of the user seated on the driver's seat. When the display system according to the invention is mounted on a moving body such as an automobile, the driver can simultaneously see a virtual image by the combiner and an external scenery.

  A display system (combiner system) according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram showing a head-up display equipped with a combiner system according to an embodiment of the present invention. FIG. 1 shows a state in which the combiner is exposed from the dashboard and is erected in a substantially vertical state and is in a state (use position) used by a user sitting in the driver's seat of the vehicle.

  The head-up display 1 shown in FIG. 1 allows a user sitting in a driver's seat of a vehicle to visually recognize various information such as navigation information superimposed on an outside scene in front of the windshield FG. , A combiner system 20 and an operation unit (not shown). The combiner system 20 includes a combiner 210, a shutter mechanism 230, and a pop-up mechanism 220 that does not appear on the drawing in FIG.

  The display device 10 projects light that draws an image representing various types of information such as navigation information toward the viewing side surface of the combiner 210 of the combiner system 20.

  The combiner 210 is a well-known half mirror in which a light semi-transmissive film such as tin or silver is vapor-deposited on a concave surface of a curved transparent resin plate, and the concave surface becomes a reflection surface (viewing side surface) 210a. In the use position shown in FIG. 1, the combiner 210 is held in a state of standing with respect to the horizontal plane, and the concave surface is held in a state of facing the display device 10 and the user side.

  The combiner 210 reflects the light projected from the display 10 toward the user by the reflecting surface 210a, thereby projecting an image representing various information such as navigation information drawn by the light onto the user's field of view. . Since the combiner 210 is a half mirror as described above, the projected image is visually recognized by the occupant through the combiner 210 as a virtual image superimposed on the outside scene in front of the windshield FG. Further, since the combiner 210 is curved, the user can visually recognize the image as it floats forward by about 2 to 3 m.

  FIG. 2 is a schematic diagram for explaining the combiner 210 and the pop-up mechanism 220 in the combiner system 20.

  As shown in FIG. 2, the combiner 210 has a shape in which a generally rectangular plate is curved in the vertical direction and the horizontal direction. The lower end of the combiner 210 in use is attached to and held by the combiner holding member 221. A cylindrical projecting drive pin 222a protrudes from the left and right side surfaces in the vicinity of the lower end of the combiner holding member 221 in the up and down direction when in use. It protrudes from. These pins provided in pairs on the left and right sides of the combiner holding member 221 have the same height direction position.

  A pair of guide members 224 and 224 ′ are disposed on the left and right sides of the combiner holding member 221. The pair of guide members 224, 224 'are provided with groove-like drive rails 223a and posture rails 223b on the opposing surfaces. The drive pin 222a and the posture pin 222b are fitted to the drive rail 223a and the posture rail 223b, respectively, and moved in the drive rail 223a and the posture rail 223b, so that the combiner 210 held by the combiner holding member 221 changes the posture. Move while changing.

  FIG. 3 is a front view of the surface on which the rail of the right guide member 224 is provided toward the reflecting surface 210a of the combiner 210. FIG. The drive pin 222a is driven to move in the drive rail 223a by a drive means (not shown). Since the distance between the drive pin 222a and the posture pin 222b is fixed, when the drive pin 222a moves in the drive rail 223a, the posture pin is positioned at a position in the posture rail 223b in which the distance between the pins is kept constant accordingly. 222b moves. Then, the position and posture of the combiner 210 change according to the positional relationship between them. Then, the combiner 210 moves between the use position and the storage position. The progress of this movement will be described with reference to FIG.

  First, in the housed state in which the combiner 210 is housed in the housed position, the drive pin 222a is located at the point A that is the end of the drive rail 223a on the driver seat side, and the posture pin 222b is similarly the driver seat of the posture rail 223b. It is located at the point a which is the end on the side. In this position, the combiner 210 is placed in a substantially horizontal direction and stored in the combiner storage portion below the use position and in the storage position on the driver's seat side. The combiner accommodating portion is located in the dashboard at a place where the entire periphery including the upper portion of the combiner 210 is substantially covered and protected.

  When the driving pin 222a is moved in the driving rail 223a in the direction of the windshield by the driving means (not shown), the combiner 210 is retracted from the driver's seat side to the windshield, while the reflecting surface 210a facing upward is driven. Gradually lean toward the seat. For example, when the drive pin 222a is positioned at the point B, the posture pin 222b is positioned at the point b, and the reflecting surface 210a of the combiner 210 is slightly inclined toward the driver's seat.

  When the driving pin 222a is further moved to the position of the point C, the posture pin 222b is positioned at the point c, the reflecting surface 210a of the combiner 210 is inclined further toward the driver's seat side, and the movement from here is performed by the combiner 210. It will be accompanied by a rise. When the drive pin 222a reaches the position of the point D, the posture pin 222b is positioned at the point d, and the reflective surface 210a of the combiner 210 is substantially directed toward the driver's seat, and the movement from here is the reflective surface of the combiner 210. The combiner 210 is raised while the angle 210a is maintained.

  When the drive pin 222a reaches the point E1, the posture pin 222b is located at the point e, the reflecting surface 210a of the combiner 210 is exposed on the dashboard, and is in a substantially vertical state facing the driver seat side.

  The shape of the drive rail 223a between the point E1 and the point E2 is a circular arc with the point e as an axis, and when the drive pin 222a moves between the point E1 and the point E2, The attitude pin 222b continues to be positioned at the point e, and the drive pin 222a rotates about this point, and the angle of the reflection surface 210a of the combiner 210 changes in the vertical direction. Since the position of the eyes (front-rear direction and height direction) differs depending on the body shape, driving posture, driving position, etc., the user appropriately selects the position of the drive pin 222a between the point E1 and the point E2, The angle of the reflective surface 210a of the combiner 210 can be adjusted to an optimum position for itself.

  As described above, the process of moving the combiner 210 from the storage position to the use position has been described with reference to FIG. 3, but the movement from the use position to the storage position is just in the reverse direction, and the description is omitted.

  The driving means for moving the driving pin 222a in the driving rail 223a is not particularly limited, and various conventionally known methods and various driving means developed for carrying out the present invention can be appropriately employed. For example, a wire may be connected to the lower end of the combiner 210 or in the vicinity thereof, and the drive pin 222a may be driven by winding from the driver's seat side or the windshield FG side, or an external gear may be provided on the drive pin 222a. The drive pin 222a may be directly driven by causing a gear (a combination of a linear gear, an external gear, and an internal gear) to be engaged with the gear rim along the drive rail 223a.

  As for the angle of the reflecting surface 210a of the combiner 210, all of the adjustment ranges in which the position of the driving pin 222a is appropriately selected between the points E1 and E2 are all referred to as “substantially vertical state” and “substantially driving”. It shall be included in the category of “state facing the seat side”.

  FIG. 4 is a schematic view of the combiner system 20 according to the present embodiment as viewed from the right side toward the reflecting surface 210a of the combiner 210 showing the locus of the combiner 210 when the combiner 210 moves from the storage position to the use position. is there. As shown in FIG. 4, the moving tip of the combiner 210 (upper end in use) once rises while moving in the space on the windshield FG side, and is in a substantially vertical state at the use position close to the driver's seat side. Therefore, when the combiner 210 moves from the storage position to the use position, it is necessary that the area indicated by A1 in FIG. 4 is open. A larger size is required.

  However, in use, the angle indicated by A2 in FIG. 4 is required to be open in consideration of the angle adjustment of the reflecting surface 210a of the combiner 210, whereas the area indicated by A3 on the windshield FG side is required. Is preferably not open. Although it also has the meaning of suppressing the intrusion of dust from the outside as much as possible, the position is an area directly exposed to sunlight entering from the windshield FG, and various parts of the combiner system 20 and other various parts located in the dashboard For example, it is desirable that the region indicated by A3 is not opened in order to protect the light from the ultraviolet rays of sunlight. Therefore, in this embodiment, the shutter mechanism (opening / closing shutter) 230 is configured by two shutters, a first shutter that opens and closes the area indicated by A2 in FIG. 4 and a second shutter that opens and closes the area indicated by A3.

  That is, when the combiner 210 is in the use position, the shutter mechanism 230 is composed of two shutters, a first shutter located on the windshield FG side from the combiner 210 and a second shutter located below the combiner 210, and By configuring both shutters to be appropriately opened and closed independently, an appropriate open / close state can be realized while being simple and compact. That is, according to the configuration of the present embodiment, when the combiner 210 is in the use position (when used), areas other than the necessary area are shielded, and when moving between the use position and the storage position (when moving), Necessary areas are opened, and all openings are shielded when in the storage position (when stored or stored).

  The shutter mechanism 230 will be described in detail with reference to FIGS. FIG. 5 is a schematic perspective view illustrating only the shutter mechanism 230 and its peripheral members extracted from the combiner system 20 of the present embodiment. FIG. 5 shows the shutter mechanism in the closed state with the combiner 210 in the storage position. As shown in FIG. 5, an upper surface 233 of the dashboard is provided with an opening 234 for the combiner 210 to appear and disappear, and the shutter mechanism 230 for opening and closing the opening 234 is the first shutter 231. And the second shutter 232.

  The first shutter 231 is positioned closer to the windshield FG than the combiner 210 when the combiner 210 is in the use position in the closed state (the state shown in FIG. 1). The first shutter 231 is connected to the other end of the first arm 235, one end of which is rotatably fixed to the vehicle side at an axis 235a parallel to the center of the reflection surface (viewing side surface) 210a. By rotating one arm 235 about the shaft 235a in the direction of arrow B, a region on the windshield FG side of the opening 234 (hereinafter referred to as “region D”) can be opened and closed by the first shutter 231. It is configured.

  On the other hand, the second shutter 232 is positioned below the combiner 210 when the combiner 210 is in the use position (the state shown in FIG. 1). Below the second shutter 232, one end is connected to the other end of the second arm 236 that is rotatably fixed to the vehicle side by a shaft 236a. The second arm 236 has an arrow C about the shaft 236a. By rotating in the direction, a region on the driver's seat side of the opening 234 (hereinafter referred to as “region E”) can be opened and closed by the second shutter 232.

  The first arm 235 and the second arm 236 that open and close the first shutter 231 and the second shutter 232 may be driven by a conventionally known method. For example, an external gear is attached to the shaft 235a or the shaft 236a. Then, it may be driven by rotating it with a power unit. Next, the process of opening and closing the shutter mechanism 230 will be described. First, the process when the combiner 210 moves from the storage position to the use position will be described.

  FIG. 6 is a schematic explanatory diagram illustrating the movement of the shutter mechanism 230 when the combiner 210 moves from the storage position to the use position in order of each process in the combiner system 20 of the present embodiment. FIG. 7 is a top view showing an example of an open / close state of the shutter mechanism 230 in the combiner system 20 of the present embodiment.

  FIG. 6A shows the shutter mechanism in the closed state in which the combiner 210 is housed in the housing position, as in FIG. 5. In this state, the drive pin 222a of the combiner 210 is located at a point A that is the end of the drive rail 223a on the driver's seat side, and the posture pin 222b is similarly the end of the posture rail 223b on the driver's seat side. Located at point a. In this position, the combiner 210 is placed in a substantially horizontal direction and stored in the combiner storage portion below the use position and in the storage position on the driver's seat side. As shown in FIG. 7A, the first shutter 231 and the second shutter 232 are both closed, and the entire area of the opening 234 is shielded.

  When the combiner 210 moves from the storage position to the use position, first, the first shutter 231 is opened as shown in FIG. The first shutter 231 is opened when the first arm 235 rotates downward, and the region D of the opening 234 opens. Thereby, the movement path | route of the first half of the combiner 210 is ensured.

  Then, the combiner 210 further moves, and the moving tip (upper end in use) of the combiner 210 begins to be exposed upward from the region D as shown in FIG. In general, this state is a state in which the drive pin 222a and the posture pin 222b are located at the point B and b, respectively, shown in FIG.

  Next, as shown in FIG. 6 (4), the second shutter 232 is opened. The second shutter 232 is opened when the second arm 235 rotates toward the driver's seat, and the region E of the opening 234 opens. Thereby, all the movement paths of the combiner 210 are ensured.

  The combiner 210 further moves, and any part of the combiner 210 moves from the position of the first shutter 231 in the closed state to the driver seat side or above and moves to a position where it does not contact the first shutter in the closed state. ), The first shutter 231 is closed. In the present embodiment, the state shown in FIG. 6 (5) has reached the use position where the combiner 210 has already been erected in a substantially vertical state. This state is a state in which the drive pin 222a and the posture pin 222b shown in FIG. 4 are located at the point E1 and the point e, respectively.

  In addition, even if the combiner 210 has not reached the use position, the first shutter 231 is after any part of the combiner 210 has moved from the closed first shutter 231 position to the driver's seat side or above, that is, If the combiner is in a position where it does not contact the closed first shutter, it can be closed at any time.

  The movement of the combiner 210 from the state of FIG. 6 (1) to the state of FIG. 6 (5) is automatically performed by one operation signal. At this time, the first shutter 231 and the second shutter 232 are driven in conjunction with the movement of the combiner 210.

  By moving the combiner 210 further from the state shown in FIG. 6 (5), the angle of the reflecting surface 210a of the combiner 210 can be tilted to the state shown in FIG. 6 (6). This state is a state where the drive pin 222a and the posture pin 222b are located at the point E2 and the point e, respectively, and the position of the combiner 210 in this state is also included in the category of the use position.

  The user can appropriately adjust the angle of the reflecting surface 210a of the combiner 210 to the optimum position from the state shown in FIG. 6 (5) to the state shown in FIG. 6 (6). The drive of the combiner 210 is performed by the user continuously pressing the fine adjustment button after a series of movements of the combiner 210 from the state of FIG. 6 (1) to the state of FIG. The user adjusts to an optimal position by appropriate adjusting means such as by appropriately rotating the fine adjustment knob. Information on the optimum position once determined by the user is separately stored in the storage means, and the angle of the reflecting surface 210a of the combiner 210 is adjusted to the optimum position according to the position information read from the storage means at the time of use. You can also.

  FIG. 7B is a top view of the periphery of the combiner 210 in the state shown in FIG. 6B. FIG. 7C is a diagram for explaining the states of the first shutter 231 and the second shutter 232. FIG. 8 is a top view in which the combiner 210 is removed from FIG. When the combiner 210 is in the use position, the first shutter 231 is closed, and the second shutter is used to ensure only the region E in which the combiner 210 moves when the angle of the reflecting surface 210a of the combiner 210 is finely adjusted. Only 232 is released. Therefore, the opening in the dashboard upper surface 233 is as small as possible. The part opened by the movement of the two shutters in conjunction can be narrowed as long as it does not contact the combiner.

  As described above, the combiner 210 moves from the storage position to the use position. In the above example, the second shutter 232 starts to move toward the open state in which the moving tip of the combiner 210 (the upper end in use) begins to be exposed upward from the region D (the state shown in FIG. 6 (3)). However, it may be done before the first shutter 231 starts moving toward the open state. If the combiner 210 is released before entering the region E, there is no limit to the timing at which the second shutter 232 starts to move toward the open state.

  The process when the combiner 210 moves from the use position to the accommodation position basically follows the reverse of the above description. First, the combiner 210 in which the angle of the reflecting surface 210a is adjusted between the state shown in FIG. 6 (5) and the state shown in FIG. 6 (6) returns to the state shown in FIG. 6 (5). (Moved to the driver's seat side), the first shutter 231 is opened. The mechanism for opening the first shutter 231 is the same as the case described above that describes the progress of the movement from the storage position to the use position. Hereinafter, the opening / closing mechanism of the first shutter 231 and the opening / closing mechanism of the second shutter 232 are the same as in the case described above that describes the progress of the movement from the storage position to the use position. Then, the combiner 210 further moves to the state shown in FIG. 6 (4). The movement of the shutter can be arbitrarily determined on the condition that the movement of the combiner is not hindered.

  Next, in this embodiment, as shown in FIG. 6 (3), the second shutter 232 is closed. In the present invention, the second shutter 232 is closed when the combiner 210 moves below the position of the second shutter 232 in which any part is closed or on the windshield side, that is, when the combiner is in the second state. It may be performed after moving to a position where the shutter 232 is not touched. Therefore, the second shutter 232 may be closed before or after the first shutter 232 is closed, which will be described later, or after the combiner 210 reaches the storage position. is there.

  In the present embodiment, when the combiner 210 further moves and the combiner 210 reaches the accommodation position, the first shutter 231 is closed. In the present invention, the first shutter 231 is closed when the combiner 210 is moved downward from the position of the first shutter 231 in which any part is closed, that is, the combiner contacts the first shutter 231. What is necessary is just to be done after moving to the position which does not. For this reason, the timing is arbitrary because it may be performed not only after the combiner 210 reaches the accommodation position as in the present embodiment but also before that.

  According to the combiner system of the present embodiment described above, the combiner accommodating portion is configured to accommodate the combiner 210 in the substantially horizontal direction at the accommodation position below the use position and on the driver's seat side. Since the combiner accommodating portion is located in the vicinity of the upper side of the dashboard where there is no protrusion downward and a relatively large space is left, the space efficiency is excellent. Further, the combiner system of the present embodiment gradually changes the direction of the reflecting surface (viewing side surface) 210a between the driver's seat side and the upper side, while using the substantially vertical state between the use position and the horizontal accommodation position. Therefore, the opening serving as a movement path for the exposure of the combiner 210 can be made smaller than the conventional configuration in which it is raised from the accommodation position to the use position by rotation. The shutter mechanism covering it can be reduced in size or simplified, and the cost can be reduced.

  Further, according to the combiner system of the present embodiment, when the combiner 210 is in the use position, the shutter mechanism (opening / closing shutter) 230 is closed to the windshield FG side from the combiner 210 and the closed first shutter 231 Since the two shutters of the closed second shutter 232 are formed below the combiner 210, it is easy to optimize the opening / closing timing of the shutter, and the entire opening 234 can be shielded when the combiner 210 is accommodated. In addition, if the two shutters of the first shutter 231 and the second shutter 232 are simultaneously and precisely controlled, the opening area during use can be made as small as possible, and ultraviolet light can enter due to external dust or sunlight. Can be strictly suppressed.

  In this embodiment, both the first shutter 231 and the second shutter 232 are centered on a predetermined axis (235a, 236a) parallel to the center of the reflecting surface (viewing side surface) 210a of the combiner 210, that is, the combiner. However, in the present invention, each shutter is not limited to the configuration of the present embodiment, and for example, a slide plate type shutter or winding A conventionally known shutter such as a take-type shutter can be employed. Any configuration may be used as long as it does not hinder the movement of the combiner between the use position and the storage position and has a function of shielding the opening when the shutter is closed.

  However, if the shutter is opened and closed by rotating about a predetermined axis as in the present embodiment, the cost can be reduced with a simple structure, and the distance between the use position and the storage position can be reduced. It is preferable because it is relatively easy to design the arrangement so as not to hinder the movement of the combiner and the degree of freedom in design is high. Further, the driving at the time of opening and closing the shutter is smooth and agile, and the shutter having the configuration of this embodiment is preferable also in this respect.

  In particular, an axis parallel to the center of the reflective surface (viewing side surface) 210a of the combiner 210, which is located closer to the driver's seat than the first shutter 231, that is, an axis perpendicular to the surface where the moving direction of the combiner changes is centered. The first shutter 231 of the present embodiment that is opened and closed by rotating downward is agile driving with a simple configuration, and it is easy to secure a moving path of the combiner between the use position and the storage position. preferable.

  While the present invention has been described with reference to the preferred embodiments and modifications, the combiner system of the present invention is not limited to the configurations of the above embodiments and modifications.

  For example, in the above-described embodiments and modifications, as a mechanism for controlling the movement and posture of the combiner, a pair of guide members 224 and 224 ′ and a pair of drive rails 223a provided on the pair of guide members 224 and 224 ′ are used. The combination of the pair of drive pins 222a and the posture pins 222b that move by being fitted to the posture rail 223b is illustrated, but the present invention is not limited to this configuration, and the combiner changes the orientation of the surface on the viewing side. Any other configuration may be adopted as long as it is configured to move between the use position and the storage position while gradually changing between the driver's seat side and the upper side. For example, the moving member attached to the lower end of the combiner can be slidably driven to the driver's seat side and the windshield side, and the combiner is directly rotated by using the shaft at the lower end of the combiner as the rotation axis. By combining a pivoting means that can change the posture of the instrument from the horizontal direction to the vertical direction and linking them together, the configuration of the intended combiner movement can be realized and can be employed in the present invention.

  Further, those skilled in the art can appropriately modify the combiner system of the present invention in accordance with conventionally known knowledge. Of course, such modifications are included in the scope of the present invention as long as they have the configuration of the combiner system of the present invention.

  In the above, a combiner system used in an automobile has been described. However, the present invention can be applied to any display system in which a display device for displaying an image is configured so that its use position and accommodation position are different. Specifically, for example, in a display system or a game machine system in which a display device is installed at a position that is easy for the user to see when used, and when it is not used, the display device is accommodated at a position that cannot be seen by the user. Can also be used.
