Description

  The present invention relates to a display object capable of exhibiting a predetermined display function while ensuring sufficient translucency.

  Utilizing the difference between the incident direction of the external light and the observation direction from the observer, the line of sight from another angular direction different from the certain angular direction is blocked while transmitting the incident light from the certain angular direction. There are known lighting and blocking devices that can be used. Examples of such daylighting and blocking devices include blinds and blindfold louvers. The daylighting and shielding apparatus usually includes a plurality of plate-like bodies arranged in a uniaxial direction, and each plate-like body is inclined with respect to the uniaxial direction.

  By the way, if there is a display that can exhibit a predetermined display function while ensuring sufficient translucency, for example, it can be used as an advertising signboard installed on a panel surface facing the outside of a window glass of a building. Is extremely useful. However, such display objects are not known.

  The present inventor can exhibit a predetermined display function while ensuring sufficient translucency by printing a predetermined display object on the plurality of plate-like bodies of the daylighting and shielding apparatus described above. I thought it was possible. Specifically, for example, the display target element is printed in a visible region that can be observed from a certain angle direction in each plate-like body, so that the observer can ensure the sufficient translucency. When observing the apparatus from the angular direction, it is possible to observe a good display object by a combination of display object elements.

  However, in order to ensure sufficient translucency for external light such as sunlight whose incident direction changes according to the time zone and season, the inclination of each plate-like body according to the incident direction of external light Although it is necessary to change the angle appropriately, the size of the visible region that can be observed from the certain angle direction on the display surface also changes by changing the inclination angle of each plate-like body. And the size of the printed display target element do not correspond. As a result, when the observer observes the apparatus from the certain angle direction, adjacent display target elements are separated from each other, and an extra blank area is inserted in the display target, or adjacent display target elements are overlapped with each other. There is a problem that a part of the display object is lost. That is, in this apparatus, there is a problem that when the incident direction of the external light changes, it is impossible to achieve both sufficient transparency and observation of a good display target by the observer.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual ones. In addition, as used in this specification, the shape and geometric conditions and the degree thereof are specified, for example, terms such as “parallel”, “orthogonal”, “identical”, length and angle values, etc. are strictly Without being bound by meaning, it should be interpreted including the extent to which similar functions can be expected.

  In this specification, terms such as “sheet”, “film”, “panel” and the like are not distinguished from each other only based on the difference in designation. Therefore, for example, a “sheet” is a concept including a member that can also be called a film or a panel. In this specification, “sheet surface (film surface, panel surface)” is the same as the planar direction of the target sheet-like member when the target sheet-like member is viewed as a whole and globally. It refers to the surface to be used. Further, in this specification, the “normal direction” used for a sheet-like (film-like, panel-like) member refers to a normal direction to the sheet surface of the member.

  FIG. 1 is a perspective view showing a display object 10 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line AA of the display object 10 of FIG.

  The display object 10 of the present embodiment can be used for various purposes, for example, for large panels of several meters to several tens of meters used for outdoor signs, road information bulletin boards, outer wall surfaces of buildings, Examples of the medium-sized panel use of several tens of centimeters to several meters used for posters, signs, building inner walls, and the like can be given.

  As shown in FIGS. 1 and 2, the display object 10 includes a plurality (five in the illustrated example) of plate-like bodies 12a to 12e arranged in the first axial direction d1. In the illustrated example, the display object 10 is disposed on the panel surface 11s facing the outside of the window glass 11 of the building. The first axial direction d1 is parallel to the panel surface 11s and is orthogonal to the normal direction nd of the panel surface 11s. In the illustrated example, the first axis direction d1 is parallel to the vertical direction, and the normal direction nd of the panel surface 11s is parallel to the horizontal direction.

  Each of the plate-like bodies 12a to 12e is made of, for example, wood or resin. When the direction in which each plate-like body 12a to 12e extends on the main cutting plane (paper surface in FIG. 2) parallel to both the first axial direction d1 and the normal direction nd of the panel surface 11s is referred to as a second axial direction d2. The length of each plate-like body 12a to 12e in the second axial direction d2 is, for example, 1 cm or more, and more specifically, for example, about 30 cm to 50 cm. Moreover, the arrangement pitch of the plate-like bodies 12a to 12e in the first axial direction d1, that is, the center interval between the adjacent plate-like bodies 12a to 12e is, for example, 10 cm or more, and more specifically, for example, about 30 cm to 50 cm. is there. In the illustrated example, the plate-like bodies 12a to 12e are configured identically.

  Each plate-like body 12a-12e has the 1st surface 21 and the 2nd surface 22 as a pair of main surface which mutually opposes. Among these, the first surface 21 is provided with a display surface 24 for performing display. More specifically, the display surface 24 includes a display 23 that performs a desired display according to a supplied voltage. The display 23 is electrically connected to a power source (not shown). Examples of display objects displayed on the display surface 24 include graphics (patterns) such as graphics, patterns, designs, colors, pictures, photographs, and characters, and information such as letters, marks, and numbers.

  As shown in FIGS. 1 and 2, the display surface 24 is inclined with respect to the first axial direction d <b> 1, and in the illustrated example, is inclined with respect to the panel surface 11 s of the window glass 11.

  More specifically, as shown in FIG. 2, the display surface 24 has one end portion located on one side in the first axial direction d1 (in the illustrated example, the upper side in FIG. 2 and the upper side in the vertical direction). The window in the normal direction nd of the panel surface 11s rather than the other end located on the other side in the first axial direction d1 (the lower side in FIG. 2 and the lower side in the vertical direction in the illustrated example) It inclines with respect to the panel surface 11s so that it may space apart from the glass 11. FIG. As can be understood from FIG. 2, according to the plate-like bodies 12 a to 12 e having such a display surface 24, an angle inclined to the other side (downward) with respect to the normal direction nd of the panel surface 11 s. Light tends to be emitted from the display surface 24 in a direction (hereinafter referred to as a second angle direction D21). Therefore, the display function from the display surface 24 can be effectively exhibited when observed from the second angle direction D21 inclined to the other side with respect to the normal direction nd. On the other hand, light incident on the display object 10 from another angular direction (hereinafter referred to as an angular direction D11 in the first angular range AR1) inclined to one side (upper side) with respect to the normal direction nd of the panel surface 11s is It is difficult to block by the plate-like bodies 12a to 12e, and it is easy to guide to the panel surface 11s through the space between the adjacent plate-like bodies 12a to 12e.

  From the viewpoint of enhancing such a tendency, the display surface 24 is in the first axial direction d1 on the main cutting plane (paper surface in FIG. 2) parallel to both the first axial direction d1 and the normal direction nd of the panel surface 11s. It is preferable to approach the panel surface 11s in the normal direction nd of the panel surface 11s stepwise or continuously from one side (upper side) to the other side (lower side). In the illustrated example, on the main cutting plane (paper surface in FIG. 2) parallel to both the first axis direction d1 and the normal direction nd of the panel surface 11s, the display surface 24 is one side in the first axis direction d1 ( From the upper side to the other side (lower side), the panel surface 11s approaches the panel surface 11s in the normal direction nd of the panel surface 11s with a constant inclination. According to the plate-like bodies 12a to 12e having such a display surface 24, the display surface 24 is directed toward the second angle direction D21 inclined to the other side (lower side) with respect to the normal direction nd of the panel surface 11s. It becomes easy to emit light from. Therefore, the display function from the display surface 24 can be effectively exhibited when observed from the second angle direction D21 inclined to the other side with respect to the normal direction nd. On the other hand, light incident on the display object 10 from the angle direction D11 within the first angle range AR1 inclined to one side (upper side) with respect to the normal direction nd of the panel surface 11s is blocked by the plate-like bodies 12a to 12e. It is difficult, and it becomes easy to guide to the panel surface 11s through the space between the adjacent plate-like bodies 12a to 12e.

In the present embodiment, the display surface 24 is inclined with respect to the first axial direction d1, but the present invention is not limited to this, and the display surface 24 is perpendicular to the first axial direction d1. Also good.
As shown in FIG. 1, each plate-like body 12a-12e is extended linearly in the direction which cross | intersects with respect to the 1st axial direction d1 which is the arrangement direction. In particular, in the illustrated example, each of the plate-like bodies 12a to 12e extends linearly in a third axial direction d3 orthogonal to both the first axial direction d1 and the normal direction nd of the panel surface 11s. Thereby, the display function from the display surface 24 can be exhibited continuously over the third axial direction d3.

  Further, as shown in FIG. 2, the plurality of plate-like bodies 12 a to 12 e are positions where the adjacent plate-like bodies 12 a to 12 e partially overlap each other when the display object 10 is observed from the second angle direction D <b> 21. In relation, they are arranged in the first axial direction d1. In the present specification, “partially overlap” means that at least a part overlaps, the whole overlaps, and the end edges overlap (that is, the end edges touch each other). Means a concept that also includes With such an arrangement, when the observer observes the display object 10 from the second angle direction D21, the display function from the display surface 24 can be continuously exhibited over the first axis direction d1.

  As shown in FIG. 1 and FIG. 2, each plate-like body 12a to 12e has a rotation axis 13 that is parallel to the display surface 24 and orthogonal to the first axial direction d1, and each plate-like body 12a to 12e. A rotational drive mechanism 14 is provided for rotationally driving the 12e around each rotational shaft 13. In the illustrated example, the rotation shaft 13 is parallel to the third axial direction d3 and is orthogonal to the normal direction nd of the panel surface 11s.

  More specifically, the rotating shaft 13 protrudes in parallel with the third axial direction d3 from both ends in the third axial direction d3 of each plate-like body 12a to 12e, and can be rotated via a bearing by a support frame (not shown). It is supported by. The rotation drive mechanism 14 is, for example, a motor, and is connected to the rotation shaft 13 of each plate-like body 12a to 12e via power transmission means (not shown) such as a gear or a belt. In addition, the motor of the rotational drive mechanism 14 may be provided separately for each plate-like body 12a to 12e, or a single motor may be provided in common to each plate-like body 12a to 12e. .

  The rotational driving force of the rotational driving mechanism 14 is transmitted to the rotational shafts 13 of the respective plate-like bodies 12a to 12e via a power transmission means (not shown), so that each of the plate-like bodies 12a to 12e rotates around the respective rotational shafts 13. Are driven to rotate. By rotating the respective plate-like bodies 12a to 12e around the respective rotation shafts 13 by the rotation drive mechanism 14, the inclination directions of the respective plate-like bodies 12a to 12e with respect to the panel surface 11s are matched with the incident direction of the external light. Can be adjusted. As a result, the incident angle range of the light guided to the panel surface 11s of the window glass 11 can be adjusted with a high degree of freedom and can be widened. On the other hand, sufficient translucency can be ensured.

  By the way, as can be understood from FIG. 2, when the plate-like bodies 12 a to 12 e are driven to rotate around the respective rotation shafts 13 by the rotation drive mechanism 14, the second axes of the adjacent plate-like bodies 12 a to 12 e. The amount of overlap in the direction d2 changes, and as a result, the size of the visible region 70 that can be observed from the second angle direction D21 in the display surfaces 24 of the respective plate-like bodies 12a to 12e changes.

  In the present embodiment, as shown in FIG. 3, an objective sensor 27 extending in the second axial direction d2 is provided at one end in the third axial direction d3 of the display 23 constituting the display surface 24. The objective sensor 27 is, for example, a reflective infrared sensor, which emits infrared rays from a plurality of positions in the second axial direction d2 in parallel with the normal direction of the first surface 21 and is adjacent to the second surface 22 of the plate-like body. By receiving the reflected infrared rays, it is possible to detect the overlapping amount in the second axis direction d2 of the adjacent plate-like bodies 12a to 12e.

  Moreover, the display 23 of each plate-shaped body 12a-12e reads the detection result of the objective sensor 27, when each plate-shaped body 12a-12e is rotationally driven by the rotational drive mechanism 14, Based on the said detection result, The display on the display surface 24 is changed. More specifically, the displays 23 of the respective plate-like bodies 12a to 12e are arranged in the second angular direction based on the detection result by the objective sensor 27 when the respective plate-like bodies 12a to 12e are rotationally driven by the rotation driving mechanism 14. The size of the visible region 70 that can be observed is defined from D 21, and the display target elements corresponding to the size are displayed in the visible region 70.

  As an example, the display on the display surface 24 when the display surfaces 24 of the respective plate-like bodies 12a to 12e form the first angle θ1 or the second angle θ2 with respect to the second angle direction D21 will be described.

  FIG. 4A shows a visible region 701 that can be observed from the second angle direction D21 when the display surfaces 24 of the respective plate-like bodies 12a to 12e form the first angle θ1 with respect to the second angle direction D21. ing. 4B shows a visible region 702 that can be observed from the second angle direction D21 when the display surfaces 24 of the respective plate-like bodies 12a to 12e form the second angle θ2 with respect to the second angle direction D21. Is shown.

  As shown to Fig.4 (a), when the display surface 24 of each plate-shaped body 12a-12e makes 1st angle (theta) 1 with respect to 2nd angle direction D21, the display 23 of each plate-shaped body 12a-12e is as follows. Based on the detection result by the objective sensor 27, the size of the visible region 701 that can be observed from the second angle direction D21 is defined, and the display target elements 301a to 301e corresponding to the size are displayed in the visible region 701. Yes. And as shown to Fig.5 (a), the two-dimensional display target 301 comes to be formed by the combination of the display target element 301a-301e which the visible region 701 of each plate-shaped body 12a-12e displays. ing.

  Further, as shown in FIG. 4B, when the display surfaces 24 of the plate-like bodies 12a to 12e form the second angle θ2 with respect to the second angle direction D21, the displays 23 of the plate-like bodies 12a to 12e. Defines the size of the visible region 701 that can be observed from the second angle direction D <b> 21 based on the detection result by the objective sensor 27, and displays the display target elements 302 a to 302 e corresponding thereto in the visible region 702. It has become. And as shown in FIG.5 (b), the two-dimensional display target 302 comes to be formed by the combination of the display target element 302a-302e which the visible region 702 of each plate-shaped body 12a-12e displays. ing.

  Thus, when each plate-like body 12a-12e is rotationally driven around each rotation axis 13 by the rotation drive mechanism 14, the display 23 of each plate-like body 12a-12e is observed from the second angle direction D21. By defining the sizes of possible visible regions 701 and 702 and displaying the corresponding display target elements 301a to 301e and 302a to 302e in the visible regions 701 and 702, the viewer can display from the second angle direction D21. When observing the object 10, it is possible to observe the good display objects 301 and 302 by combining the display object elements 301a to 301e and 302a to 302e, and the display object elements adjacent to each other are separated from each other in the display object. Prevents problems such as blank areas being inserted or adjacent display target elements partially overlapping and missing part of the display target

  In this Embodiment, as shown in FIG. 2, the reflective surface 25 is provided in the 2nd surface 22 of each plate-shaped body 12a-12e. As an example, the reflecting surface 25 is formed of a thin film made of a material having a high reflectance. The reflecting surface 25 reflects light incident on the second surface 22 from an angle direction inclined further to the one side (upper side) than the angle direction D11 in the first angle range AR1, and guides the light to the panel surface 11s. Therefore, by providing the reflecting surface 25 on the second surface 22, the first angle range AR1 corresponding to the incident angle range of the light guided to the panel surface 11s can be widened.

  Next, the operation of the display object 10 as described above will be described.

  The display object 10 according to the present embodiment is arranged such that a first axial direction d1 that is an arrangement direction of the plurality of plate-like bodies 12a to 12e is parallel to the vertical direction. More specifically, the plate-like bodies 12a to 12e are inclined to one side (upper side) in the first axial direction d1 with respect to the normal direction nd of the panel surface 11s, that is, the plate-like bodies 12a to 12e. One end portion located on one side in the first axial direction d1 is located on the upper side in the vertical direction, and the other end portion located on the other side in the first axial direction d1 of each plate-like body 12a to 12e is in the vertical direction. The display object 10 is arranged so as to be located on the lower side of the screen.

  The display surfaces 24 of the respective plate-like bodies 12a to 12e are inclined to one side (upper side) in the first axial direction d1 with respect to the normal direction nd of the panel surface 11s, and thus with respect to the normal direction nd. Light tends to be emitted from the display surface 24 toward the second angular direction D21 inclined to the other side (lower side) in the first axial direction d1. Therefore, the display function from the display surface 24 can be effectively exhibited when observed from the second angle direction D21 inclined to the other side with respect to the normal direction nd.

  On the other hand, the display surfaces 24 of the respective plate-like bodies 12a to 12e are inclined to one side (upper side) in the first axial direction d1 with respect to the normal direction nd of the panel surface 11s. The light incident on the display object 10 from the angular direction D11 within the first angular range AR1 inclined to one side (upper side) in the first axial direction d1 is taken into the space between the adjacent plate-like bodies 12a to 12e. Is possible. The light taken into the space between the adjacent plate bodies 12a to 12e travels through the space between the adjacent plate bodies 12a to 12e and is guided to the panel surface 11s.

  By the way, as mentioned in the column of the problem to be solved by the invention, in order to ensure sufficient translucency for external light such as sunlight whose incident direction changes according to the time zone and season. It is necessary to change the inclination angle of each plate-like body 12a to 12e according to the incident direction of external light. By changing the inclination angle of each plate-like body 12a to 12e, the second of the display surfaces 24 is changed. The size of the visible region 70 that can be observed from the angular direction D21 also changes. Therefore, when the display target element is printed on the display surface 24, the size of the visible region 70 on the display surface 24 and the size of the printed display target element are changed by changing the inclination angle of each plate 12a to 12e. No longer responds. As a result, when the observer observes the display device from the second angle direction D21, the adjacent display target elements are separated from each other and an extra blank area is inserted in the display target, or the adjacent display target elements overlap each other. There is a problem that a part of the display object is lost.

  On the other hand, in the present embodiment, when the plate-like bodies 12a to 12e are rotationally driven around the rotation shaft 13 by the rotation drive mechanism 14, the displays 23 of the plate-like bodies 12a to 12e are detected by the objective sensor 27. Based on the result, the size of the visible region 70 that can be observed from the second angle direction D <b> 21 in the display surface 24 is defined, and the display target element corresponding to the size is displayed in the visible region 70.

  Specifically, for example, when the display surfaces 24 of the plate-like bodies 12a to 12e form the first angle θ1 with respect to the second angle direction D21, the displays 23 of the plate-like bodies 12a to 12e are connected to the objective sensor 27. The size of the visible region 701 that can be observed from the second angle direction D <b> 21 is defined based on the detection result of, and the display target elements 301 a to 301 e corresponding thereto are displayed in the visible region 701. Thereby, when the observer observes the display object 10 from the second angle direction D21, the two-dimensional display object 301 is favorably observed by the combination of the display object elements 301a to 301e. For example, when the display surfaces 24 of the plate-like bodies 12a to 12e form the second angle θ2 with respect to the second angle direction D21, the displays 23 of the plate-like bodies 12a to 12e are detected by the objective sensor 27. Based on the above, the size of the visible region 702 that can be observed from the second angle direction D21 is defined, and the display target elements 302a to 302e corresponding to the size are displayed in the visible region 702. Thereby, when the observer observes the display object 10 from the second angle direction D21, the two-dimensional display object 302 is favorably observed by the combination of the display object elements 302a to 302e.

  That is, in the present embodiment, when each plate-like body 12a to 12e is rotationally driven around the rotation shaft 13 by the rotation drive mechanism 14, the second angle direction of the display surface 24 of each plate-like body 12a to 12e. Although the size of the visible region 70 that can be observed changes from D21, the display 23 appropriately changes the size of the display target element so as to correspond to the size of the visible region 70 based on the detection result by the objective sensor 27. By doing so, adjacent display target elements are separated from each other and an extra blank area is inserted in the display target, or adjacent display target elements are partially overlapped and a part of the display target is not lost, It is possible to satisfactorily observe the display target by combining the display target elements. Therefore, according to the present embodiment, even when the incident direction of external light changes, ensuring both sufficient translucency and allowing an observer to observe a good display target are compatible. can do.

  As described above, according to the present embodiment, the plurality of plate-like bodies 12a to 12e are arranged in the first axial direction d1, and the plate-like bodies 12a to 12e are driven to rotate around the respective rotation shafts 13. A rotating drive mechanism 14 is provided. For this reason, even if the incident direction of external light changes, each plate-like body 12a-12e is rotated around each rotating shaft 13 by the rotational drive mechanism 14, and each plate is changed according to the incident direction of external light. Sufficient translucency can be ensured by changing the inclination angles of the bodies 12a to 12e.

  Moreover, according to this Embodiment, the display surface 24 of each plate-shaped body 12a-12e consists of the display 23 which performs a desired display according to the supplied voltage, and each plate-shaped body 12a by the rotational drive mechanism 14 is comprised. ˜12e are rotationally driven around the respective rotation axes 13, the display 23 defines the size of the visible region 70 that can be observed from a certain angular direction (second angular direction D21) of the display surface 24. A display target element corresponding to the display target element is displayed in the visible region 70, and a display target is formed by a combination of the display target elements. For this reason, when each plate-shaped body 12a-12e is rotated by the rotational drive mechanism 14, the magnitude | size of the visible region 70 which can be observed from the 2nd angle direction D21 among the display surfaces 24 of each plate-shaped body 12a-12e. However, when the observer observes the display object 10 from the second angle direction D21 by appropriately changing the size of the display target element so that the display 23 corresponds to the size of the visible region 70, Adjacent display target elements are separated from each other, and an extra blank area is inserted in the display target, or adjacent display target elements are partially overlapped and a part of the display target is not lost. The display object by combination can be observed favorably.

  That is, according to the present embodiment, the display object 10 that allows an observer to observe a good display object while ensuring sufficient translucency even when the incident direction of light changes. Can be provided.

  In particular, in the display object 10 according to the present embodiment, the first angle range AR1, which is the incident angle range of light transmitted through the display object 10, is set in a direction inclined upward in the vertical direction, and the display surface 24 is observed. The possible second angle direction D21 is set in a direction inclined downward in the vertical direction. In this case, it is effective when the display object 10 is installed at a position higher than the line of sight in an application as a billboard-installed advertising signboard assumed as a typical use. Since the observer observes the display object 10 while looking up at the upper side in the vertical direction, the observer can observe the display target displayed on the display surface 24 from the second angle direction D21 inclined downward in the vertical direction. On the other hand, although the incident direction of sunlight changes depending on the time zone and season, it is incident on the display object 10 while proceeding in a direction inclined downward in the vertical direction or in a substantially horizontal direction. For this reason, even if an incident direction changes according to a time zone or a season, sunlight is between the plate-shaped bodies 12a-12e adjacent from the angle direction D11 in 1st angle range AR1 inclined to the upper side in a perpendicular direction. It can go to the panel surface 11s of the window glass 11 through this space.

  Moreover, according to this Embodiment, since the reflective surface 25 is provided in the 2nd surface 22 of each plate-shaped body 12a-12e, it inclines further further than the angle direction D11 in 1st angle range AR1. The incident light from the angle direction toward the second surface 22 can be reflected and guided to the panel surface 11 s of the window glass 11. Thereby, the first angle range AR1 corresponding to the incident angle range of the light guided to the panel surface 11s can be widened.

By the way, Table 1 below shows the south-middle altitude (°) for each season in major cities in some countries of the world. It is preferable that the south and middle altitudes of the equinox in the major cities of the country where the use is assumed be included in the first angle range AR1. This is because there is a high possibility that it can be used effectively in that country. For example, when the country assumed to be used is Japan, the altitude from 54 ° to 56 ° may be included in the first angle range AR1. Furthermore, it is preferable that an altitude of 49 ° to 61 ° is included in the first angle range AR1, since there is a high possibility that it can be used effectively in many countries in the world. Further, it is more preferable that the first angular range AR1 includes a range from the southern middle altitude of the summer solstice to the southern middle altitude of the winter solstice in the main cities of the country where use is assumed. This is because there is a high possibility that it can be used effectively throughout the year in that country. For example, when the country assumed to be used is Japan, the altitude from 31 ° to 79 ° may be included in the first angle range AR1. Furthermore, it is preferable that an altitude of 25 ° to 84 ° is included in the first angle range AR1, since it is highly likely that the altitude can be effectively used in many countries in the world. In order to make it easy for the desired altitude to be included in the first angle range AR1, it is preferable that the angle range of the first angle range AR1 is continuous by about 45 ° or more. However, it is also possible to make the desired altitude included in the first angle range AR1 by arranging the display object 10 at an angle. On the other hand, the upper limit of the angle range of the first angle range AR1 may be set as appropriate depending on the balance with the second angle direction D21. Can be exhibited more.

  In the present embodiment, the display 23 defines the size of the visible region 70 that can be observed from the second angle direction D21 based on the detection result by the objective sensor 27. However, the present invention is not limited to this. Not. For example, the servo motor of the rotation drive mechanism 14 can detect the tilt angle of the display surface 24 with respect to the first axis direction d1, and the display 23 reads the detection result of the servo motor of the rotation drive mechanism 14 and detects the detection result. Based on the result, the size of the visible region 70 that can be observed from the second angular direction D21 may be defined.

  Moreover, in this Embodiment, although the display object 10 was arrange | positioned on the panel surface 11s of the window glass 11 of a building, it is not limited to this. For example, the display object 10 may be arrange | positioned on the panel surface of the solar cell panel of wall surface installation.
