DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (First embodiment) Hereinafter, a first embodiment of the present invention will be described with reference to Figs. 1 to 4. As shown in Figs. 1 to 3, a support device 30 according to the first embodiment is a support device 30 for supporting a projection device (electronic device) 10 in a vertical position, and includes a front support member (first support member) 40 and a rear support member (second support member) 50. With the support device 30, the installation angle (projection angle) of the projection device 10 can be adjusted while the projection device 10 is supported. The projection device 10 includes a housing 20 having a substantially rectangular box shape and six faces (upper face 20a, lower face 20b, left side face 20c, right side face 20d, front face (light exit face) 20e, and rear face 20f). The projection device 10 has a projection port 11 from which projection light is emitted on the front face 20e side.

[0010] In the following description, the left and right of the projection device 10 refer to the left and right directions relative to the direction of emission of the projection light from the projection port 11, and the front and rear refer to the front and rear directions relative to the direction of travel of the projection light of the projection device 10, when the projection device 10 is laid flat. The upper surface 20a side is the upper side of the projection device 10, and the lower surface 20b side is the lower side of the projection device 10. The thickness direction of the projection device 10 refers to the up and down direction of the projection device 10. In the projection device 10, a projection port opening 22a through which the projection port 11 is exposed, a front intake port 22b, and an exhaust port 22c are provided on the front surface 20e side of the housing 20. A plurality of reinforcing ribs 22c1 extending like a beam and reinforcing the exhaust port 22c are provided on the opening surface of the exhaust port 22c (see FIG. 2 and FIG. 10).

[0011] The state where the projection device 10 is placed flat refers to an installation state where the bottom surface 20b faces the installation surface IS (see FIG. 4) and projects a horizontally elongated projection image, and the state where the projection device 10 is placed vertically refers to an installation state where the right side surface 20d faces the installation surface IS and projects a vertically elongated projection image. The state where the projection device 10 is placed horizontally refers to an installation state where the rear surface 20f faces the installation surface IS and projects a horizontally elongated projection image onto a ceiling or the like. The left and right directions with respect to the emission direction of the projection light in each installation state may be referred to as the left and right sides for the sake of explanation.

[0012] The upper surface 20a of the housing 20 is provided with an operation panel 24 for performing settings of the projection device 10, and an adjustment opening 20a1 exposing a part of an adjustment ring 26 for adjusting a lens barrel (not shown) provided inside the housing 20. The front part of the lower surface 20b of the housing 20 is provided with a tilt mechanism 28 (see FIGS. 2 and 3) for adjusting the installation angle of the housing 20 with the projection device 10 laid flat. The left side surface 20c of the housing 20 is provided with a left air intake (not shown) and a connector connection port (not shown) for image input / output, and the right side surface 20d of the housing 20 is provided with a power cord connection port (not shown) for supplying power to the projection device 10. An AC cord 10C is connected to the power cord connection port.

[0013] Next, the support device 30 will be described in detail. When the support device 30 is used to support the projection device 10 in a vertical position, the front support member 40 is a member that supports the right side surface 20d of the projection device 10 at different positions depending on the installation angle, and the rear support member 50 is a member that supports the projection device 10 together with the front support member 40 by holding the right side surface 20d of the projection device 10 at a predetermined height. In the following, in the support device 30 in a state where the projection device 10 is supported in a vertical position, the thickness direction of the projection device 10 (the vertical direction of the projection device 10) is the left-right direction of the support device 30 (the upper surface side of the projection device 10 is the left side), the arrangement direction of the front support member 40 and the rear support member 50 is the front-rear direction of the support device 30 (the front support member 40 side is the front side), and the left-right direction of the projection device 10 is the up-down direction of the support device 30 (the left side surface 20c side of the projection device 10 is the upper side).

[0014] As shown in FIG. 2, the front support member 40 is substantially concave when viewed from the front side, and is provided with a front bottom member (first bottom member) 42 that is placed on the installation surface IS, and a pair of front plates (plurality of first side plates) 44 that rise up from both the left and right ends of the front bottom member 42 in plate-like shapes and are arranged opposite to each other, which are integrally configured. The front bottom member 42 has an upper surface 42a that is a flat surface parallel to the installation surface IS. Each front plate 44 has the same size and shape, rises up from the front bottom member 42 so as to be perpendicular to the installation surface IS, and has its upper end parallel to the upper surface 42a of the front bottom member 42. The pair of front plates 44 are slightly larger than the dimension in the thickness direction of the projection device 10, and face each other in parallel with a gap therebetween.

[0015] A connecting member 46 is provided between the pair of front side plates 44 to connect the two front side plates 44. Furthermore, bearings (not shown) are provided on the inner surfaces of the pair of front side plates 44 so as to face each other. The connecting member 46 is a cylindrical shaft-like member, and both ends are supported by the bearings and are rotatable around the shaft. The connecting member 46 is provided at a position separated from the upper surface 42a of the front bottom member 42 and at a portion near the front end of the front support member 40. Furthermore, a rubber-like member 46R is provided on the outer circumferential surface of the connecting member 46 (see FIG. 1).

[0016] As shown in FIG. 3, the rear support member 50 is substantially concave when viewed from the rear side, and is provided with a rear bottom member 52 placed on the installation surface IS and a pair of rear plates (multiple second side plates) 54 that rise from both left and right ends of the rear bottom member 52 in a plate-like shape and are arranged opposite to each other, which are integrally configured. The rear bottom member 52 has an upper surface 52a that is a flat surface parallel to the installation surface IS, and a lower surface (end surface) 52b that is a convex arc shape toward the installation surface IS. Therefore, when placed on the installation surface IS, the rear bottom member 52 can be tilted freely along the convex arc shape of the lower surface 52b. The rear plates 54 have the same dimensions and shape, rise from the rear bottom member 52 so as to be perpendicular to the installation surface IS, and their upper surfaces are parallel to the upper surface 52a of the rear bottom member 52. The pair of front plates 44 face each other in parallel at a distance substantially equal to the dimension in the thickness direction of the projection device 10.

[0017] A clamp mechanism (not shown) for adjusting the distance between the pair of rear plates 54 is provided inside the rear bottom member 52. The rear support member 50 can hold the projection device 10 by clamping it in its thickness direction with this clamp mechanism.

[0018] Next, an example of a support mode of the projection device 10 using the support device 30 according to the present embodiment will be described. As shown in FIG. 1, when the projection device 10 is supported in a vertical position using the support device 30, the projection device 10 is placed in a vertical position with the upper surface 20a facing the left side, the front portion of the right side surface 20d of the projection device 10 is supported by the front support member 40, and the rear portion of the projection device 10 near the right side surface 20d is supported by the rear support member 50. In the support device 30, the support position of the projection device 10 in the front support member 40 is changed while the support position of the projection device 10 in the rear support member 50 is fixed, thereby changing the installation angle of the projection device 10 supported in a vertical position. Note that the housing 20 of the projection device 10 may be provided with a switch that switches the projection screen projected from the projection port 11 to a vertical screen when supported by the rear support member 50.

[0019] First, a case where the projection device 10 is supported vertically without an installation angle, i.e., with an installation angle of 0 degrees, will be described. In this case, the projection device 10 is placed vertically so that the projection port opening 22a opening to the front side is located on the upper side, and the front support member 40 places the front part of the right side surface 20d of the projection device 10 on the upper surface 42a of the front bottom surface member 42. This supports the front part of the projection device 10. Meanwhile, the rear support member 50 places the rear part of the projection device 10 close to the right side surface 20d between a pair of rear plates 54, and clamps the projection device 10 in its thickness direction by a clamp mechanism. At this time, the projection device 10 is clamped at a position where the right side surface 20d of the projection device 10 supported by the front support member 40 and the rear support member 50 is parallel to the installation surface IS. This fixes the rear part of the projection device 10, holds the right side surface 20d of the projection device 10 at a predetermined height, and supports the projection device 10.

[0020] By supporting the projection device 10 in this manner, as shown in FIG. 4(a), the installation angle of the projection device 10 is set to 0 degrees, and the housing 20 of the projection device 10 is set to a state horizontal to the installation surface IS (hereinafter referred to as the "horizontal state"). In the horizontal state, the emission direction of the projection light from the projection port 11 is parallel to the installation surface IS, and the connecting member 46 faces the front surface 20e of the projection device 10. As shown in FIG. 2, in the horizontal state, the front portions of the upper surface 20a and the lower surface 20b of the projection device 10 on the right side surface 20d side are in close proximity to or in contact with the pair of front side plates 44. Therefore, the front side plates 44 prevent the front portions of the right side surface 20d side of the projection device 10 from falling in the left-right direction due to vibration or the like.

[0021] Furthermore, in the horizontal state, one of the reinforcing ribs 22c1 provided on the exhaust port 22c of the projection device 10 overlaps with the connecting member 46 when viewed from the front side of the front support member 40. In other words, the connecting member 46 is provided at a position corresponding to one of the reinforcing ribs 22c1 when the installation angle of the projection device 10 is 0 degrees. Therefore, the flow of exhaust air from the exhaust port 22c is prevented from being blocked by the connecting member 46. Also, as shown in FIG. 3, in the horizontal state, a gap CL is provided between the upper surface 52a of the rear bottom member 52 and the rear portion of the right side surface 20d of the projection device 10, so that the AC cord 10C connected to the projection device 10 can be routed through this gap CL. This prevents the AC cord 10C from interfering with the rear support member 50, and the rear portion of the projection device 10 can be reliably fixed by the rear support member 50.

[0022] Next, a description will be given of a case where the projection device 10 is supported vertically with an installation angle set for the projection device 10, that is, with the projection device 10 tilted with respect to the installation surface IS. In this case, as shown in FIG. 4(b), in the front support member 40, the front portion of the right side surface 20d of the projection device 10 is placed on the connecting member 46. With the rear support member 50, the projection device 10 is tilted rearward along the lower surface of the rear bottom member 52, which is in a convex arc shape, with the projection device 10 fixed. As a result, an installation angle is set for the projection device 10, and the emission direction of the projection light from the projection port 11 is tilted upward with respect to the installation surface IS (hereinafter, the state shown in FIG. 4(b) is referred to as the "first tilt state").

[0023] When the installation angle of the projection device 10 is increased from the first tilt state, that is, when the projection device 10 is further tilted with respect to the installation surface IS, the front support member 40 is moved backward to approach or abut against the rear support member 50 as shown in FIG. 4(c). This makes the projection device 10 in a state where it is further tilted than the first tilt state (hereinafter, the state shown in FIG. 4(c) is referred to as the "second tilt state"). When the front support member 40 is moved backward, the connecting member 46 on which the projection device 10 is placed rotates around its axis, so that the front support member 40 can be moved smoothly while supporting the projection device 10. Furthermore, since the rubber-like member 46R is provided on the outer circumferential surface of the connecting member 46, a large frictional force acts between the housing 20 of the projection device 10 and the connecting member 46, so that the projection device 10 supported on the connecting member 46 is unlikely to be displaced.

[0024] In the first tilt state and the second tilt state, a part of the upper portion of each front side plate 44 faces the projection device 10 in a state close to or in contact with the projection device 10. Therefore, even if the projection device 10 tilts left or right when the front support member 40 is moved rearward, the portion of each front side plate 44 close to or in contact with the projection device 10 prevents or suppresses the projection device 10 from tilting.

[0025] As described above, in the support device 30 of the present embodiment, the housing 20 of the projection device 10 is placed vertically, and the rear portion of the projection device 10 is fixed by the rear support member 50, while the front portion of the projection device 10 is supported by the front support member 40, and the front support member 40 is moved, thereby allowing the projection device 10 to be tilted to a desired installation angle. In other words, by changing the distance between the front support member 40 and the rear support member 50, the installation angle of the projection device 10 can be changed according to the distance. Note that, when changing the installation angle of the projection device 10 from the first tilt state to the second tilt state, the installation angle of the projection device 10 can be further increased by moving the rear support member 50 forward together with the projection device 10 in a state in which the front portion of the projection device 10 is placed on the connecting member 46, without moving the front support member 40 backward.

[0026] Here, the support device 30 according to the present embodiment can support the projection device 10 not only in a vertical position but also in a horizontal position. In this case, as shown in FIG. 5, for example, the projection device 10 is placed in a horizontal position with the front surface 20e facing upward (the projection port opening 22a is open on the upward side), the right side of the rear surface 20f of the projection device 10 is supported by the front support member 40, and the left side of the projection device 10 near the rear surface 20f is supported by the rear support member 50. Specifically, the front support member 40 places the right side of the rear surface 20f of the projection device 10 on the upper surface 42a of the front bottom member 42, and the rear support member 50 places the left side of the projection device 10 near the rear surface 20f between a pair of rear plates 54, and clamps the projection device 10 by a clamp mechanism. In this way, the support device 30 can support the projection device 10 in a horizontal position.

[0027] Next, a first modified example of this embodiment will be described. As shown in Fig. 6, a support device 130A according to the first modified example is configured to further include a stopper member 47 as part of the support device 30 according to Figs. 1 to 5. The stopper member 47 is a substantially plate-shaped member, and is attached to the rear side of the front support member 40 in a state in which it is placed on the installation surface IS.

[0028] In the support device 130A according to the first modification, when the front support member 40 is brought closer to the rear support member 50 by a predetermined distance or more, the rear end of the stopper member 47 interferes with the rear support member 50, and the front support member 40 is restricted from coming any closer to the rear support member 50. This makes it possible to prevent the projection device 10 from falling backward together with the support device 130 due to the distance between the front support member 40 and the rear support member 50 becoming too narrow and the projection device 10 being excessively tilted backward. The dimension of the stopper member 47 in the front-rear direction can be adjusted according to the desired minimum distance between the front support member 40 and the rear support member 50, in other words, the maximum installation angle of the projection device 10.

[0029] Next, a second modified example of this embodiment will be described. As shown in Fig. 7, in the support device 130B according to the second modified example, the height of the upper surface 152a of the rear bottom surface member 152 from the installation surface IS when the rear support member 150B is not tilted is set to be substantially equal to the height of the upper surface 42a of the front bottom surface member 42 from the installation surface IS. Therefore, by placing the rear portion of the right side surface 20d of the projection device 10 on the upper surface 152a of the rear bottom surface member 152 with the front portion of the right side surface 20d of the projection device 10 placed on the upper surface 42a of the front bottom surface member 42, the projection device 10 can be supported in a horizontal state.

[0030] In the rear bottom member 152 of this modified example, a groove-shaped storage space SP for inserting the AC cord 10C and the plug portion of the AC cord 10C is provided at approximately the center in the left-right direction of the upper surface 152a of the rear bottom member 152 toward the rear surface of the rear bottom member 152. Therefore, the rear portion of the right side surface 20d of the projection device 10 can be placed on the upper surface 152a of the rear bottom member 152 without the AC cord 10C interfering with the upper surface 152a of the rear bottom member 152.

[0031] As described above, the support device 30 according to this embodiment includes a front support member 40 having a pair of front side plates 44 arranged opposite to each other and a connecting member 46 connecting the pair of front side plates 44 at a position spaced apart from the installation surface IS, and the connecting member 46 supports the right side surface 20d of the projection device 10 according to the installation angle of the projection device 10 relative to the installation surface IS in a state in which the pair of front side plates 44 face each other in the thickness direction of the projection device 10. Therefore, by moving the front support member 40 in the front-rear direction in a state in which the right side surface 20d of the projection device 10 is supported by the connecting member 46, the inclination angle of the projection device 10 relative to the installation surface IS can be set to any angle. In this way, the support device 30 can support the projection device 10 in a vertical position at a desired installation angle.

[0032] Moreover, in the support device 30, the connecting member 46 is provided in an axial shape. This allows the right side surface 20d of the projection device 10 to be placed on the connecting member 46 and supported easily. Furthermore, in the support device 30, the connecting member 46 is provided rotatably around the axis. This allows the front support member 40 to move smoothly in the front-rear direction while the right side surface 20d of the projection device 10 is supported on the connecting member 46. Furthermore, in the support device 30, the connecting member 46 is provided with a rubber-like member 46R on its outer circumferential surface. This increases the frictional force acting between the right side surface 20d of the projection device 10 supported on the connecting member 46 and the connecting member 46, making it difficult for the projection device 10 supported on the connecting member 46 to be displaced.

[0033] Moreover, in the support device 30, the front support member 40 is placed on the installation surface IS and has a front bottom member 42 from which a pair of front plates 44 stand, and the front bottom member 42 has an upper surface 42a on which the right side surface 20d of the projection device 10 can be placed. Therefore, by placing the projection device 10 on the upper surface 42a of the front bottom member 42, the projection device 10 can be supported in a stable manner.

[0034] In addition, in the support device 30, the upper surface 42a of the front bottom member 42 is a surface that is horizontal to the installation surface IS. Therefore, by placing the projection device 10 on the upper surface 42a of the front bottom member 42, the projection device 10 can be supported so as to be horizontal to the installation surface IS.

[0035] The support device 30 is for supporting the projection device 10 having a front surface 20e on which the projection port 11 and the exhaust port 22c are provided, and the connecting member 46 is provided at a position facing the front surface 20e of the projection device 10 when the projection device 10 is placed on the upper surface 42a of the front bottom member 42. As a result, if the front support member 40 is displaced rearward with the projection device 10 placed on the upper surface 42a of the front bottom member 42, the connecting member 46 interferes with the front surface of the projection device 10, and therefore the front support member 40 can be prevented from being displaced excessively.

[0036] The support device 30 is for supporting the projection device 10 in which the reinforcing rib 22c1 is provided at the exhaust port 22c along the front surface 20e of the projection device 10, and the connecting member 46 is provided at a position corresponding to the reinforcing rib 22c1 when the projection device 10 is placed on the upper surface 42a of the front bottom member 42. This prevents the exhaust from the exhaust port 22c from being blocked by the connecting member 46 in the vicinity of the reinforcing rib 22c1 at a position corresponding to the connecting member 46 in the exhaust port 22c, so that the support device 30 can be used to support the projection device 10 in a vertical position without deteriorating the exhaust function of the projection device 10.

[0037] The support device 30 also includes a rear support member 50 that supports the projection device 10 together with the front support member 40 by holding the right side surface 20d of the projection device 10 at a predetermined height, and the distance between the front support member 40 and the rear support member 50 is changeable, and the installation angle changes depending on the distance. Therefore, even when the support device 30 is placed upright, the projection device 10 can be supported in a stable manner by supporting the projection device 10 with both the front support member 40 and the rear support member 50. Furthermore, by changing the distance between the front support member 40 and the rear support member 50, the installation angle of the projection device 10 can be changed depending on the distance.

[0038] Moreover, in the support device 30, the rear support member 50 has a pair of rear plates 54 arranged opposite to each other, and supports the projection device 10 by sandwiching the projection device 10 between the pair of rear plates 54 in the thickness direction according to the installation angle with respect to the installation surface IS. Therefore, by sandwiching the rear portion of the projection device 10 using the pair of rear plates 54 of the rear support member 50, the rear portion of the projection device 10 can be fixed while being supported by the rear support member 50. In this way, a specific configuration for reliably supporting the rear portion of the projection device 10 can be provided.

[0039] Moreover, in the support device 30, the rear support member 50 has a rear bottom member 52 from which a pair of rear plates 54 stand. This makes it possible to place the rear bottom member 52 on the installation surface IS while supporting the projection device 10 by sandwiching it between the pair of rear plates 54.

[0040] In addition, in the support device 30, the rear support member 50 is placed on the installation surface IS, and the end face is formed into a convex arc shape toward the installation surface IS. Therefore, by tilting the rear support member 50 along the end face formed into a convex arc shape, the projection device 10 supported and fixed by the rear support member 50 can be easily tilted.

[0041] Second embodiment Next, a second embodiment of the present invention will be described with reference to Figs. 8 to 11. In the description of the second embodiment, the description of the same configuration as the first embodiment will be omitted or simplified. As shown in Fig. 8, the support device 230 according to the second embodiment includes a front support member 240 that supports the front part of the projection device 10 in a vertically placed state, and a rear support member 250 that supports the rear part of the projection device 10, similar to the support device 30 of the first embodiment. The front support member 240 includes a front bottom member 242, a pair of front plates 244, and a connecting member 246. In the front support member 240, the height dimension of the front bottom member 242 is higher than the height dimension of the front bottom member 42 of the first embodiment. The other configurations of the front support member 240 are the same as the front support member 40 of the first embodiment.

[0042] The connecting member 246 has the same configuration as the connecting member 46 of the first embodiment. That is, the connecting member 246 is a cylindrical shaft-like member provided in a shape that connects both front side plates 244, and is journaled on both front side plates 244 so as to be rotatable about its axis. A rubber-like member 246R is provided on the outer circumferential surface of the connecting member 246.

[0043] As shown in FIG. 8 and FIG. 9, the rear support member 250 includes an installation member 251 installed on an installation surface IS, a rear bottom member (second bottom member) 252, and a pair of rear plates (second side plates) 254 that rise from both left and right ends of the rear bottom member 252 in a plate-like shape and are arranged opposite each other. The rear bottom member 252 and the pair of rear plates 254 are integrally configured and provided. The installation member 251 is in the shape of a rectangular column (thick plate), and its upper surface 251a is a flat surface parallel to the installation surface. A rotating part support part 251a1 that rotatably supports the rear bottom member 252 is provided in the approximate center of the upper surface 251a of the installation member 251. The rotating part support part 251a1 is made of a pair of plate-like members that rise slightly upward with both plate surfaces facing the left and right directions, and the upper end part is formed into a convex arc shape.

[0044] The rear bottom member 252 has an upper surface 252a that is a flat surface parallel to the installation surface IS, and a rotating part 252b that extends from the center of the lower surface to the installation member 251 side with both plate surfaces facing in the left-right direction is provided. The rotating part 252b has a convex arc-shaped lower end and is rotatably sandwiched between a pair of plate members of the rotating part support part 251a1. The rotating part 252b is rotatable around an axis along the left-right direction and can be fixed at any rotation position. A clamp mechanism (not shown) for adjusting the distance between the pair of rear plates 254 is provided inside the rear bottom member 252. In the rear support member 250, the projector 10 can be sandwiched and held in its thickness direction by this clamp mechanism while the rotating part 252b is fixed at any rotation position.

[0045] As shown in FIG. 8 and FIG. 9, a connecting member 260 is provided between the front support member 240 and the installation member 251 of the rear support member 250 to connect them in an expandable and contractible manner. The connecting member 260 is composed of two cylindrical shaft-like members spaced apart in the left-right direction, with their front ends connected to the front support member 240 and their rear ends connected to the installation member 251. The rear part of the connecting member 260 is a large diameter part 262, and the front part is a small diameter part 264 having a smaller diameter than the large diameter part 262. The connecting member 260 is contracted by fitting the small diameter part 264 inside the large diameter part 262, and further fitting the large diameter part 262 with the small diameter part 264 inside the installation member 251. By contracting the connecting member 260, the distance between the front support member 240 and the rear support member 250 can be narrowed.

[0046] Next, an example of a support mode of the projection device 10 using the support device 230 according to this embodiment will be described. When the projection device 10 is supported vertically without providing an installation angle to the projection device 10, the front support member 240 places the front portion of the right side surface 20d of the projection device 10 on the upper surface 242a of the front bottom surface member 242, and the rear support member 250 places the rear portion of the right side surface 20d of the projection device 10 between a pair of rear side plates 254, and the clamp mechanism holds the projection device 10 in its thickness direction. At this time, the projection device 10 is held at a position where the right side surface 20d of the projection device 10 supported by the front support member 240 and the rear support member 250 is parallel to the installation surface IS. Alternatively, the height of the upper surface 252a of the rear bottom member 252 from the mounting surface IS can be set equal to the height of the upper surface 242a of the front bottom member 242 from the mounting surface IS, and the rear portion of the right side 20d of the projection device 10 can be placed on the upper surface 252a of the rear bottom member 252, and then the projection device 10 can be clamped by a clamp mechanism.

[0047] As shown in Fig. 10(a) and Fig. 11(a), when the projection device 10 is supported in a vertical position with the projection device 10 tilted with respect to the installation surface IS, in the front support member 40, the front portion of the right side surface 20d of the projection device 10 is placed on the connecting member 46. With respect to the rear support member 50, with the projection device 10 fixed, the rotating portion 252b is rotated to tilt the rear bottom member 252 rearward, and then fixed. This provides an installation angle to the projection device 10, and the emission direction of the projection light from the projection port 11 is tilted upward with respect to the installation surface IS (hereinafter, the state shown in Fig. 10(a) and Fig. 11(a) is referred to as the "third tilt state").

[0048] The installation angle of the projection device 10 can be further increased by contracting the connection member 260 from the third tilt state and moving the front support member 240 closer to the installation member 251 of the rear support member 250. As in the first embodiment, when the front support member 240 is moved rearward, the coupling member 246 on which the projection device 10 is placed rotates about its axis, so that the front support member 240 can be moved smoothly while supporting the projection device 10. At this time, the rubber-like member 246R provided on the outer circumferential surface of the coupling member 246 prevents the projection device 10 moving on the coupling member 246 from slipping.

[0049] When the projection device 10 is tilted at the maximum angle with respect to the installation surface IS, as shown in Fig. 10(b) and Fig. 11(b), the connection member 260 is contracted to store the large diameter portion 262 inside the installation member 251, and the front support member 240 is abutted against the installation member 251 (hereinafter, the state shown in Fig. 10(b) and Fig. 11(b) is referred to as the "fourth tilt state"). In the fourth tilt state, the tilt angle θ1 of the projection device 10 with respect to the installation surface IS is set to 30 degrees or more. In other words, the connecting member 246 is provided at a height such that when the front support member 240 and the rear support member 250 are abutted against each other, the angle that the right side surface 20d of the projection device 10 supported by the connecting member 246 makes with respect to the installation surface IS is 30 degrees or more.

[0050] Furthermore, the support device 230 of this embodiment may be configured such that a control unit is provided inside the front support member 240 or the rear support member 250, and the connection member 260 can be electrically extended and contracted from a distance. In other words, the support device 230 may be configured such that the distance between the front support member 240 and the rear support member 250 can be electrically adjusted while the projection device 10 is supported.

[0051] As described above, in the support device 230 according to the second embodiment, the rear support member 250 has an installation member 251 that is installed on the installation surface IS and rotatably supports the rear bottom member 252, and further includes a connection member 260 that expands and contracts and supports the front support member 240 and the installation member 251. Therefore, the installation member 251 can hold the rear bottom member 252 at a desired rotation angle, and the projection device 10 supported by the front support member 240 and the rear support member 250 can be easily held in a state tilted at a desired installation angle.

[0052] Furthermore, by providing the connection member 260, when the front support member 240 is moved toward the installation member 241 (toward the rear support member 250) in order to tilt the projection device 10 to a desired installation angle, the connection member 260 prevents the front support member 240 from shaking, and the front support member 240 supporting the projection device 10 can be moved stably. Therefore, the projection device 10 supported by the front support member 240 and the rear support member 250 can be easily tilted to a desired installation angle.

[0053] Furthermore, in the support device 230 according to the second embodiment, the connecting member 246 is provided at a height such that the angle that the right side surface 20d of the projection device 10 supported by the connecting member 246 makes with the installation surface IS is 30 degrees or more when the front support member 240 and the rear support member 250 are brought into contact with each other. This allows the front support member 240 and the rear support member 250 to stably support the projection device while tilting it at an installation angle of 30 degrees or more.

[0054] The above-described embodiments are presented as examples, and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims. For example, in each of the above embodiments, a configuration in which the upper surface of the front support member is a surface parallel to the installation surface is illustrated, but a lowered step may be provided in the front part of the upper surface of the front support member so that the projection member supported by the front support member can be tilted forward. Also, for example, in each of the above embodiments, a configuration in which the front support member has a pair of front side plates and the rear support member has a pair of rear side plates is illustrated, but it is sufficient that at least two front side plates and two rear side plates are provided, and a configuration in which three or more front side plates and three or more rear side plates are provided may be provided.
