Description

[Technical Field]

[0001] The present disclosure relates to a projector device, a stand-equipped projector device, and a support device. [Background technology]

[0002] 2. Description of the Related Art A support base for supporting a projector is known (see, for example, Patent Document 1). The support base described in Patent Document 1 includes a fixed portion and a rotating portion. The fixed portion is provided on the opposite side of the rotating portion from the projector and rotatably supports the rotating portion. The rotating portion has a pair of projector support portions that rotatably support the projector. When the rotating portion rotates relative to the fixed portion, the projector supported by the projector support portions of the rotating portion also rotates in accordance with the movement of the rotating portion. This allows the user to arbitrarily set the projection direction of the image light from the projector by combining the up and down movement of the projector with the left and right movement of the rotation part.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-27369 Summary of the Invention [Problem to be solved by the invention]

[0004] In recent years, the uses of projectors have become more diverse, and there is a demand for a configuration in which the height position of the projector can be adjusted by connecting a stand such as a tripod. In response to this, it is conceivable to provide the support base described in Patent Document 1 with a configuration in which a stand can be attached to the fixed portion. However, when attaching the fixing part to, for example, a tripod mounting screw, the entire support base needs to be rotated relative to the tripod, which poses a problem of difficulty in fixing the support base to the tripod. In particular, since the fixing part rotatably supports the rotating part that supports the relatively heavy projector, the fixing part is required to be heavy in order to prevent the support base from tipping over. This poses a problem of difficulty in fixing the support base to a tripod placed on an installation surface by rotating the support base including the fixing part and the projector together. For this reason, there has been a demand for a configuration that allows for easy attachment of the stand. [Means for solving the problem]

[0013] [First embodiment] Hereinafter, a first embodiment of the present disclosure will be described with reference to the drawings. [Configuration of projector with stand] FIG. 1 is a side view showing a stand-equipped projector device SP1 according to this embodiment. As shown in FIG. 1, a stand-equipped projector SP1 according to this embodiment is configured by combining a stand SD and a projector 1A.

[0014] [Stand configuration] The stand SD is detachably attached to the projector apparatus 1A to be supported, and supports the projector apparatus 1A. In this embodiment, the stand SD is a tripod that is detachable from a support device 3A (described later) of the projector apparatus 1A, and has three legs SD1, a platform SD2, and a screw portion SD3. Each of the three legs SD1 is configured to be extendable and retractable. The platform SD2 is the part that comes into contact with the support object of the stand SD and supports the support object. The screw portion SD3 is exposed on the platform SD2 and is inserted into a support object. In this embodiment, the platform SD2 comes into contact with a first surface 71 of a support member 7 (described later) and the screw portion SD3 is fixed to a stand mounting portion 64 of the base 6A (described later), thereby mounting the stand SD to the projector 1A.

[0015] [Projector equipment configuration] FIG. 2 is a perspective view showing the projector device 1A, and FIG. 3 is a perspective view showing the projector device 1A as seen from the opposite side to that of FIG. As shown in FIGS. 1 to 3, the projector device 1A includes a projector 2A that projects image light PL and a support device 3A that supports the projector 2A, and is configured by combining the projector 2A and the support device 3A.

[0016] [Projector configuration] The projector 2A includes an exterior housing 20 that houses an image projection device (not shown). The exterior housing 20 has a front surface 21, a back surface 22, a top surface 23, a bottom surface 24, a left side surface 25, and a right side surface 26, and is formed in a substantially rectangular parallelepiped shape. The front surface 21 and the back surface 22 are outer surfaces facing opposite directions in the exterior housing 20. Image light PL projected from an image projection device (not shown) is projected to the outside of the projector 2A via a projection port 211 provided on the front surface 21. The projection port 211 projects the image light PL in the +Z direction, which will be described later. The top surface 23 and the bottom surface 24 are outer surfaces facing opposite directions on the exterior housing 20. The top surface 23 intersects with the front surface 21, the back surface 22, the left side surface 25, and the right side surface 26. The bottom surface 24 intersects with the front surface 21, the back surface 22, the left side surface 25, and the right side surface 26. The left side surface 25 and the right side surface 26 are outer surfaces facing opposite directions on the exterior housing 20. The left side surface 25 is provided with an engagement portion 251 that engages with an arm 8L (described later) of the stand device 3A, and the right side surface 26 is provided with an engagement portion 261 that engages with an arm 8R (described later) of the stand device 3A.

[0017] [Support device configuration] The support device 3A rotatably supports the projector 2A and is configured to allow the above-mentioned stand SD to be attached and detached. The support device 3A includes a support device main body 4A having a table 5A, a base 6A, and a support member 7, and a connecting member 8. Hereinafter, the three mutually orthogonal directions are referred to as the +X direction, the +Y direction, and the +Z direction. In this embodiment, when the projector 1A is installed on an installation surface, the direction perpendicularly moving away from the installation surface is referred to as the +Y direction. In other words, the XZ plane defined by the +X direction and the +Z direction orthogonal to the +Y direction is a plane parallel to the installation surface. In other words, the direction from the table 5A toward the base 6A along a first rotation axis Rx1 (described later) is referred to as the +Y direction. Although not shown, the direction opposite the +X direction is the -X direction, the direction opposite the +Y direction is the -Y direction, and the direction opposite the +Z direction is the -Z direction. Furthermore, the axis along the +X direction is the X axis, the axis along the +Y direction is the Y axis, and the axis along the +Z direction is the Z axis.

[0018] Configure Table Fig. 4 is a cross-sectional view showing the support device 3A, Fig. 5 is an exploded perspective view showing the support device 3A as viewed from the +Y direction, and Fig. 6 is an exploded perspective view showing the support device 3A as viewed from the -Y direction. The table 5A is a portion that comes into contact with the installation surface when the projector 1A is installed on the installation surface. The table 5A is formed in a disk shape, and when the table 5A is combined with the base 6A and the support member 7, it is configured to be rotatable relative to the base 6A about a first rotation axis Rx1 along the Y axis. 4, the table 5A has a first surface 51 that faces the installation surface when the projector device 1A is installed on the installation surface, and a second surface 52 that is opposite to the first surface 51. The first surface 51 faces in the -Y direction, and the second surface 52 faces in the +Y direction.

[0019] As shown in FIGS. 4 to 6, the table 5A further includes a through-hole 53, a protruding portion 54, an installation portion 55, and a recess 56. The through portion 53 is a circular through-hole formed in the center of the table 5A when viewed from the +Y direction or the -Y direction, and passes through the table 5A along the Y axis. More specifically, the through portion 53 encompasses the first rotation axis Rx1 and passes through the table 5A along the Y axis. In the through portion 53, the stand mounting portion 64 of the base 6A is disposed from the +Y direction, and the support member 7 is disposed from the -Y direction.

[0020] The protruding portion 54 is a portion that protrudes from the inner edge of the through portion 53 toward the inside of the through portion 53. In other words, the protruding portion 54 is a portion that protrudes from the inner edge of the through portion 53 toward the center of the through portion 53. More specifically, the protruding portion 54 protrudes from the +Y direction portion of the inner edge of the through portion 53 toward the center of the through portion 53. Therefore, the through portion 53 is a stepped hole in which the diameter of the edge in the -Y direction is large and the diameter of the edge in the +Y direction is small.

[0021] The installation portion 55 is provided on the first surface 51 and is in contact with the installation surface. That is, the −Y direction surface 551 of the installation portion 55 is an opposing surface of the installation portion 55 that faces the installation surface, and is located in the −Y direction from the first surface 51. 3 and 6, the installation portions 55 are rubber feet arranged at equal intervals in the circumferential direction around the first rotation axis Rx1 on the first surface 51, and come into contact with the installation surface. In this embodiment, the number of installation portions 55 is four, but the number of installation portions 55 can be changed as appropriate as long as it is one or more. Furthermore, the installation portion 55 may be formed in a ring shape along the circumferential direction around the first rotation axis Rx1.

[0022] As shown in FIGS. 4 and 5 , the recess 56 is recessed from the second surface 52 in the −Y direction and is formed in a ring shape centered on the first rotation axis Rx1. When the table 5A and the base 6A are combined, a plurality of arc-shaped guide portions 68 are inserted into the recess 56 from the +Y direction. This guides the rotation of the base 6A relative to the table 5A about the first rotation axis Rx1. It is preferable to apply a lubricant such as grease to the sliding surfaces between the recess 56 and the guide portions 68. Alternatively, a slit may be formed on the surface of the guide portion 68 facing the recess 56, and the recess 56 may have a protruding piece that is inserted into the slit of the guide portion 68.

[0023] [Base configuration] 4 to 6, the base 6A is disposed in the +Y direction with respect to the table 5A and covers the table 5A in the +Y direction. The base 6A is connected to the table 5A so as to be rotatable relative to the table 5A about a first rotation axis Rx1. The base 6A has a first surface 61 facing in the -Y direction and a second surface 62 facing in the +Y direction and opposite to the first surface 61. The first surface 61 and the second surface 62 are inclined in a direction away from the table 5A in the +Z direction and in a direction approaching the table 5A in the -Z direction. However, the present invention is not limited to this, and the first surface 61 and the second surface 62 may be parallel to at least one of the first surface 51 and the second surface 52 of the table 5A.

[0024] Furthermore, the base 6A has an annular portion 63, a stand mounting portion 64, a first protruding portion 65, a member receiving surface 66, a second protruding portion 67, and a guide portion 68. 4 and 6, the annular portion 63 is an annular part that protrudes from the first surface 61 toward the table 5A side and surrounds the periphery of the through portion 53. The annular portion 63 is formed along the circumferential direction centered on the first rotation axis Rx1.

[0025] The stand mounting portion 64, the first protrusion 65, and the member receiving surface 66 are provided inside the annular portion 63. As shown in FIG. 4, when the table 5A and the base 6A are combined, the stand mounting portion 64, the first protrusion 65, and the member receiving surface 66 are located inside the through-hole portion 53 when viewed from the -Y direction. The stand SD can be attached to the stand attachment portion 64, which is a cylindrical portion protruding from the first surface 61 in the -Y direction. That is, the stand attachment portion 64 is disposed on the surface of the base 6A facing the installation surface. The stand attachment portion 64 is located on the first rotation axis Rx1, and the center of a surface 641 of the stand attachment portion 64 facing the -Y direction intersects with the first rotation axis Rx1. The surface 641 is the surface facing the installation surface, and a stand fixing portion 642 is provided in the center of the surface 641. The stand SD is fixed to the stand fixing portion 642. In this embodiment, as described above, the stand SD is a tripod, and the stand fixing portion 642 is a screw hole to which the screw portion SD3 of the stand SD shown in FIG. 1 is fixed.

[0026] The first protrusion 65 protrudes from the first surface 61 in the −Y direction. The member receiving surface 66 is provided in an area of ​​the -Y direction surface of the first protruding portion 65 that is located inside the through-hole 53 when viewed from the -Y direction. The member receiving surface 66 is a receiving surface that receives the second surface 72 in the +Y direction of the support member 7 that is inserted into the through-hole 53 from the -Y direction. The member receiving surface 66 is provided with a member fixing portion 661 to which the support member 7 is fixed. A fixture Fx that fixes the support member 7 is fixed to the member fixing portion 661, whereby the support member 7 is fixed to the member fixing portion 661 with the support member 7 in contact with the member receiving surface 66. In this embodiment, the fixture Fx is a screw, and the member fixing portion 661 is a screw hole into which the tip of the fixture Fx that has passed through the support member 7 is inserted.

[0027] 4 and 5, the second protrusion 67 protrudes annularly from the first surface 61 in the circumferential direction centered on the first rotation axis Rx1 at a position outside the through-hole 53 when viewed from the -Y direction. More specifically, the second protrusion 67 protrudes in the -Y direction from the first surface 61 in accordance with the recess 56 provided in the table 5A in the circumferential direction centered on the first rotation axis Rx1. A plurality of guide portions 68 are provided on an end surface 671 of the second protrusion 67 in the -Y direction. That is, the plurality of guide portions 68 are provided on the end surface 671 at equally spaced positions in the circumferential direction centered on the first rotation axis Rx1. As shown in FIG. 4, the plurality of guide portions 68 are inserted into the recess 56 from the +Y direction when the table 5A and the base 6A are combined. The recess 56 and the guide portions 68 guide the rotation of one of the table 5A and the base 6A relative to the other about the first rotation axis Rx1.

[0028] [Support member configuration] The support member 7 is formed in a disk shape and is inserted into the inside of the through-hole 53 of the table 5A from the -Y direction. The support member 7 faces the protruding portion 54 and is fixed to the base 6A in a state of contact with the member receiving surface 66, allowing the table 5A to rotate relatively with respect to the base 6A. Specifically, the support member 7 is fixed to a member fixing portion 661 of the base 6A. In addition to supporting the table 5A together with the base 6A, the support member 7 forms a stand receiving surface that receives the pan head SD2 of the stand SD attached to the stand attachment portion 64 described above. As shown in Figures 4 to 6, the support member 7 has a first surface 71 facing the -Y direction and a second surface 72 facing the +Y direction and opposite the first surface 71, as well as a through hole 73, a flange portion 74, and multiple insertion holes 75.

[0029] The through hole 73 is circularly formed in the center of the support member 7 when viewed from the -Y direction or the +Y direction, and penetrates the support member 7 in the direction from the first surface 71 to the second surface 72. That is, the through hole 73 penetrates the support member 7 along the Y axis. A cylindrical stand attachment portion 64 is inserted into the through hole 73 from the +Y direction. That is, when the table 5A, the base 6A, and the support member 7 are combined with each other, the support member 7 exposes the stand attachment portion 64 in the -Y direction, which is the installation surface side, through the through hole 73. At this time, the first rotation axis Rx1 along the Y axis is located inside the through hole 73.

[0030] The flange portion 74 is a portion that protrudes outward from a -Y direction portion of a circumferential surface 76 of the support member 7 that is centered on the first rotation axis Rx1. More specifically, the flange portion 74 is a portion that protrudes outward in the radial direction centered on the first rotation axis Rx1 from the -Y direction portion of the circumferential surface 76, and is formed in a circular shape when viewed from the -Y direction. The +Y direction surface of flange portion 74 faces the -Y direction surface of protruding portion 54 when support member 7 is disposed inside through portion 53. When support member 7 is disposed inside through portion 53, flange portion 74 and protruding portion 54 may be in contact with each other on the Y axis or may be spaced apart from each other.

[0031] The multiple insertion holes 75 are provided around the through hole 73. More specifically, the multiple insertion holes 75 are arranged at equal intervals around the outside of the through hole 73 in the circumferential direction centered on the first rotation axis Rx1. In this embodiment, three insertion holes 75 are provided, and each insertion hole 75 penetrates the support member 7 along the Y axis. A fastener Fx is inserted into each of the multiple insertion holes 75 from the -Y direction. The fastener Fx is inserted through each insertion hole 75 in the +Y direction and is fixed to the member fixing portion 661, thereby fixing the support member 7 to the base 6A.

[0032] In this way, when the support member 7 is fixed to the member fixing portion 661 of the base 6A so as to sandwich the protruding portion 54 of the table 5A between the support member 7 and the base 6A, the first surface 71 of the support member 7 functions as a second receiving surface that receives the stand SD. In other words, the first surface 71 corresponds to the stand receiving surface of the support member 7. At this time, the first surface 71 is located in the +Y direction of a surface 551 on the −Y direction of the installation portion 55 of the table 5A in the Y axis along which the first rotation axis Rx1 runs, and is located in the −Y direction of the first surface 51 of the table 5A. In other words, the first surface 61 corresponding to the second receiving surface is located between the first surface 51 on the installation surface side of the table 5A and the surface 551 on the installation surface side of the installation portion 55 in the direction along the first rotation axis Rx1. Furthermore, a surface 641 exposed toward the installation surface at the stand mounting portion 64 of the base 6A disposed within the through-hole 73 of the support member 7 is located closer to the base 6A in the direction along the first rotation axis Rx1 than a surface 551 of the installation portion 55 facing the installation surface. Specifically, the surface 641 in the -Y direction at the stand mounting portion 64 is located in the +Y direction in the direction along the first rotation axis Rx1 than the surface 551 of the installation portion 55 facing the -Y direction. The surface 641 corresponds to the exposed surface at the stand mounting portion 64.

[0033] [Attaching the stand to the support device] When attaching the stand SD to the support device 3A, as described above, the platform SD2 of the stand SD shown in Fig. 1 is brought into contact with the first surface 71 of the support member 7, and the screw portion SD3 is fixed to the stand fixing portion 642 of the stand attachment portion 64 exposed in the -Y direction. This allows the stand SD to be attached to the support device 3A, and ultimately to the projector device 1A.

[0034] [Configuration of connecting members] The connecting member 8 stands upright on the base 6A of the support device main body 4A and is connected to the projector 2A. That is, the connecting member 8 constitutes a connecting portion that is connected to the projector 2A on the base 6A. The connecting member 8 has a pair of arms 8L, 8R that are provided at the end of the base 6A in the +Z direction. Arm 8L is provided on a portion of side surface 6L of base 6A facing the -X direction in the +Z direction, and is connected to a left side surface 25 of projector 2A. Arm 8R is provided on a portion of side surface 6R of base 6A facing the +X direction in the +Z direction, and is connected to a right side surface 26 of projector 2A. The left side surface 25 corresponds to the first surface, and the right side surface 26 corresponds to the second surface. 5, the arm 8L has a hinge 8L1 connected to the left side surface 25, and the arm 8R has a hinge 8R1 connected to the right side surface 26, as shown in Fig. 6. The pair of arms 8L, 8R enable the projector 2A to rotate about a second rotation axis Rx2, which is perpendicular to an axis parallel to the first rotation axis Rx1, via the hinges 8L1, 8R1.

[0035] [Effects of the first embodiment] The stand-equipped projector SP1 according to this embodiment described above has the following advantages. The stand-equipped projector SP1 includes a projector 1A and a stand SD attached to a stand attachment portion 64 of a support device 3A of the projector 1A. The projector device 1A includes a projector 2A and a support device 3A, and the support device 3A includes a table 5A, a base 6A, and a connecting member 8. The table 5A has a through-hole 53. The base 6A is connected to the table 5A so as to be rotatable relative to the table about a first rotation axis Rx1 that is perpendicular to an installation surface on which the table 5A can be installed. The connecting member 8 corresponds to a connecting portion and stands upright on the base 6A. The projector 2A is connected to a connecting member 8. The base 6A has a stand mounting portion 64 that is arranged on a first surface 61 on the installation side of the base 6A and to which a stand can be attached. The stand mounting portion 64 is located inside the through-hole 53 when the table 5A and the base 6A are combined.

[0036] With this configuration, when attaching the projector 1A to the tripod serving as the stand SD, it is only necessary to rotate the base 6A relative to the threaded portion SD3 serving as the tripod screw, and there is no need to rotate the table 5A. Therefore, the stand SD and the projector 1A can be easily fixed together. Furthermore, since the base 6A is rotatable relative to the table 5A, there is a slight clearance between the base 6A and the table 5A. On the other hand, the stand SD is attached to the stand attachment portion 64 of the base 6A, which is provided with a connecting member 8 that connects to the projector 2A. Therefore, compared to when the stand SD is attached to the table 5A, it is possible to prevent the projector 2A from shaking in the projector device 1A to which the stand SD is attached. Therefore, it is possible to prevent the image projected by the projector 2A from shaking.

[0037] The projector device 1A includes a protruding portion 54, a member receiving surface 66, and a support member 7. The protruding portion 54 is provided on the table 5A and is a portion that protrudes inward from the through-hole 53. The member receiving surface 66 corresponds to a first receiving surface. The member receiving surface 66 is provided on the base 6A and is disposed inside the through-hole 53. The support member 7 faces the protruding portion 54 and is fixed to the base 6A in a state of contact with the member receiving surface 66. The support member 7 enables the table 5A to rotate relatively to the base 6A. The support member 7 exposes the stand mounting portion 64 in the -Y direction, which is the installation surface side. With this configuration, the table 5A can be sandwiched between the base 6A and the support member 7 fixed to the base 6A. This allows the table 5A to be attached so as to be rotatable relative to the base 6A. Furthermore, since the support member 7 exposes the stand attachment portion 64, the stand SD can be easily attached to the stand attachment portion 64.

[0038] In the projector device 1A, the first surface 71 of the support member 7 on the installation surface side forms a receiving surface that receives the platform SD2 of the stand SD. That is, the first surface 71 forms a second receiving surface. The first surface 71 is located closer to the installation surface than the first surface 51 on the installation surface side of the table 5A. That is, the first surface 71 is located in the -Y direction from the first surface 51. With this configuration, the first surface 71 of the support member 7 forms a receiving surface that receives the stand SD, so the contact area between the projector 1A and the stand SD can be increased, which makes it possible to prevent the projector 1A from tilting relative to the stand SD. Furthermore, the stand SD does not interfere with the table 5A when attached to the first surface 71. This prevents the stand SD from coming into contact with the table 5A when the stand SD is attached, thereby preventing damage to the table 5A.

[0039] In the projector 1A, the table 5A has an installation portion 55 that can come into contact with the installation surface. A surface 641 of the stand attachment portion 64 that is exposed toward the installation surface corresponds to the exposed surface, and is located closer to the base 6A than a surface 551 of the installation portion 55 in the +Y direction along the first rotation axis Rx1. In other words, the surface 641 is located in the +Y direction than the surface 551. The surface 551 is an opposing surface of the installation portion 55 that faces the installation surface. With this configuration, when the projector 1A is installed on an installation surface by the installation section 55, it is possible to prevent the stand attachment section 64 from coming into contact with the installation surface before the installation section 55. Therefore, the projector 1A can be stably installed on the installation surface.

[0040] In the projector 1A, the table 5A has an installation portion 55 that can come into contact with the installation surface. A first surface 71 serving as a second receiving surface is located between the first surface 51 on the installation surface side of the table 5A and a surface 551 on the installation surface side of the installation portion 55 in the +Y direction along the first rotation axis Rx1. With this configuration, when the projector 1A is installed on an installation surface by the installation section 55 as described above, it is possible to prevent the stand attachment section 64 from coming into contact with the installation surface before the installation section 55. Therefore, the projector 1A can be stably installed on the installation surface. Furthermore, the first surface 71 is located in the -Y direction, which is closer to the installation surface than the first surface 51 of the table 5A. This makes it easier to bring the platform SD2 of the stand SD into contact with the first surface 71. This makes it easy to attach the stand SD to the projector device 1A.

[0041] In the projector device 1A, the stand mounting portion 64 is located on the first rotation axis Rx1. In the projector 1A, the first rotation axis Rx1 of the table 5A and the base 6A, which are rotatable relative to each other, is generally set in consideration of the weight balance of the entire projector 1A. Since the stand mounting portion 64 is provided on this first rotation axis Rx1, it is possible to easily maintain the weight balance of the projector 1A even after the stand SD is mounted.

[0042] In the projector device 1A, the projector 2A has a left side surface 25 and a right side surface 26 located on opposite sides to each other. One of the left side surface 25 and the right side surface 26 corresponds to a first surface, and the other corresponds to a second surface. A connecting member 8 serving as a connecting portion includes a pair of arms 8L, 8R. The pair of arms 8L, 8R are connected to the left side surface 25 and the right side surface 26 via hinges 8L1, 8R1 that enable the projector 2A to rotate around a second rotation axis Rx2 that is perpendicular to an axis parallel to the first rotation axis Rx1. In this embodiment, the second rotation axis Rx2 is perpendicular to the first rotation axis Rx1. According to this configuration, the projector 2A can be rotated around the second rotation axis Rx2. This allows the projector 2A to rotate around both the first rotation axis Rx1 and the second rotation axis Rx2, which makes it possible to expand the directions in which the projector 2A can project image light, thereby improving the convenience of the projector device 1A.

[0043] The support device 3A includes a table 5A, a base 6A, a connecting member 8, and a stand mounting portion 64. The table 5A has a through-hole 53. The base 6A is connected to the table 5A so as to be rotatable relative to the table 5A about a first rotation axis Rx1 that is perpendicular to an installation surface on which the table 5A can be installed. The connecting member 8 constitutes a connecting portion. The connecting member 8 stands upright on the base 6A and is configured so that the projector 2A can be connected to it. The stand attachment portion 64 is disposed on the first surface 61 of the base 6A on the installation surface side. The stand attachment portion 64 is located inside the through-hole 53, and the stand SD can be attached to the stand attachment portion 64. With this configuration, the stand SD and the projector 1A can be easily fixed together.

[0044] [Second embodiment] Next, a second embodiment of the present disclosure will be described. The stand-equipped projector device according to this embodiment has the same configuration as the stand-equipped projector device according to the first embodiment, but differs in that the object to which the stand SD is attached is a projector, and that a through-hole through which the stand is inserted is provided in the support device. Note that in the following explanation, parts that are the same or approximately the same as parts already explained will be assigned the same reference numerals and explanations thereof will be omitted.

[0045] [Projector device with stand and schematic configuration of projector device] Fig. 7 is a side view showing a stand-attached projector SP2 according to this embodiment, Fig. 8 is a perspective view of a projector 1B constituting the stand-attached projector SP2 as seen from the +Y direction, and Fig. 9 is a perspective view of the projector 1B as seen from the -Y direction. 7, the stand-attached projector SP2 according to this embodiment has the same configuration and functions as the stand-attached projector SP1 according to the first embodiment, except that it has a projector 1B instead of the projector 1A. That is, the stand-attached projector SP2 has the projector 1B and a stand SD. As shown in FIGS. 7 to 9, the projector device 1B includes a projector 2B and a support device 3B that supports the projector 2B, and has the same functions as the projector device 1A according to the first embodiment.

[0046] [Projector configuration] 9 instead of the bottom surface 24. That is, the projector 2B has an exterior housing 20 having a front surface 21, a rear surface 22, a top surface 23, a bottom surface 24B, a left side surface 25, and a right side surface 26. The bottom surface 24B is a surface facing the base 6B that constitutes the support device 3B.

[0047] The projector 2B further includes a stand mounting portion 24B1. The stand mounting portion 24B1 is provided on the bottom surface 24B, and the stand SD is mounted to the stand mounting portion 24B1. In this embodiment, the stand mounting portion 24B1 has a receiving surface 24B2 that receives the pan head SD2 of the stand SD, and also has a stand fixing portion 24B3 that is provided on the receiving surface 24B2 and to which the screw portion SD3 of the stand SD is fixed. The pan head SD2 comes into contact with the receiving surface 24B2, and the screw portion SD3 is fixed to the stand fixing portion 24B3, whereby the stand SD is mounted to the bottom surface 24B and ultimately to the projector 2B. That is, in this embodiment, the bottom surface 24B corresponds to a first receiving surface that receives the stand SD. The stand mounting portion 24B1 is provided on the first rotation axis Rx1, and more specifically, the stand fixing portion 24B3 is provided on the first rotation axis Rx1.

[0048] [Support device configuration] FIG. 10 is a bottom view showing the projector device 1B as seen from the -Y direction. The support device 3B supports the projector 2B rotatably about the second rotation axis Rx2, similar to the support device 3A according to the first embodiment. The support device 3B includes a support device main body 4B having a table 5B and a base 6B shown in FIGS. 7 to 10, and a connecting member 8 provided on the base 6B. In other words, the support device 3B according to this embodiment does not include the support member 7.

[0049] Configure Table Like the table 5A according to the first embodiment, the table 5B is a part that comes into contact with the installation surface when the projector 1B is installed on the installation surface. The table 5B is formed in a ring shape when viewed from the -Y direction, and is configured to be rotatable relative to the base 6B about a first rotation axis Rx1 when combined with the base 6B. Table 5B has the same configuration and function as table 5A, except that it has a through-hole 5B1 provided on the first rotation axis Rx1 instead of the through-hole 53 and the protruding portion 54. That is, as shown in Figures 9 and 10, table 5B has a first surface 51, an installation portion 55, and the through-hole 5B1, as well as a second surface 52 and a recess 56 (not shown). The through-hole 5B1 is formed in a circular shape centered on the first rotation axis Rx1 and penetrates the table 5B along the first rotation axis Rx1. A part of the stand SD is inserted into the through-hole 5B1 along the Y axis. That is, the stand SD attached to the stand attachment part 24B1 can be inserted into the through-hole 5B1 in the ±Y directions along the first rotation axis Rx1. The diameter of the through-hole 5B1 is larger than the diameter of the through-hole 53 of the table 5A according to the first embodiment.

[0050] [Base configuration] Similar to the base 6A according to the first embodiment, the base 6B is disposed in the +Y direction with respect to the table 5B and covers the table 5B in the +Y direction. The base 6B is provided to be rotatable relative to the table 5B about a first rotation axis Rx1. The base 6B has the same configuration and function as the base 6A, except that it has a through-hole 6B1 provided on the first rotation axis Rx1 instead of the stand mounting portion 64, the first protrusion 65, and the member receiving surface 66. That is, the base 6B has a first surface 61, a second surface 62, a second protrusion 67, a guide portion 68, and the through-hole 6B1. The through-hole 6B1 is formed in a circular shape centered on the first rotation axis Rx1 and penetrates the base 6B along the first rotation axis Rx1. A part of the stand SD is inserted into the through-hole 6B1 along the Y axis. That is, the stand SD attached to the stand attachment part 24B1 can be inserted into the through-hole 6B1 in the ±Y directions along the first rotation axis Rx1. When the base 6B and the table 5B are combined, the through-hole 6B1 is connected to the through-hole 5B1 to form an insertion part TP through which the stand SD is inserted along the Y axis. That is, the support device 3B has the insertion part TP through which the stand SD is inserted along the Y axis, and the support device 3B is configured in a ring shape centered on the first rotation axis Rx1, excluding the connecting member 8.

[0051] [Attaching the stand to the projector] When attaching the stand SD to the projector device 1B, the stand SD is inserted into the insertion part TP from the -Y direction. After that, with the platform SD2 of the stand SD in contact with the receiving surface 24B2, which is part of the bottom surface 24B of the projector 2B, the screw part SD3 is fixed to the stand fixing part 24B3 of the stand attachment part 24B1. This allows the stand SD to be attached to the projector 2B, and ultimately to the projector device 1B.

[0052] [Effects of the second embodiment] The stand-equipped projector SP2 according to this embodiment described above has the following advantages. The projector device 1B includes a projector 2B and a support device 3B, and the support device 3B includes a table 5B, a base 6B, and a connecting member 8. The table 5B can be placed on an installation surface. The base 6B is connected to the table 5B so as to be rotatable relative to the table 5B about a first rotation axis Rx1 perpendicular to the installation surface. The connecting member 8 corresponds to a connecting portion and stands upright on the base 6B. The projector 2B has a stand mounting portion 24B1 on a bottom surface 24B facing the base 6B, to which the stand SD can be mounted, and is connected to a connecting member 8. The table 5B has a through-hole 5B1 that penetrates the table 5B along the first rotation axis Rx1 and through which the stand SD attached to the stand attachment part 24B1 can be inserted in the ±Y directions along the first rotation axis Rx1. The base 6B has a through-hole 6B1 that penetrates the base 6B along the first rotation axis Rx1 and through which the stand SD attached to the stand attachment part 24B1 can be inserted in the ±Y directions along the first rotation axis Rx1.

[0053] According to this configuration, the stand SD can be attached to the stand attachment portion 24B1 of the projector 2B through the through-holes in the table 5B and the base 6B. Therefore, the stand SD can be easily brought into contact with the stand attachment portion 24B1 of the projector 2B, and therefore the stand SD can be easily attached to the projector device 1B. Furthermore, since the stand SD is attached to the stand attachment portion 24B1 provided on the projector 2B, it is possible to prevent the projector 2B from shaking in the projector device 1B to which the stand SD is attached, compared to when the stand SD is attached to the table 5B. Therefore, it is possible to prevent the image projected by the projector 2B from shaking.

[0054] In the projector 1B, the through-holes 5B1 and 6B1 are located on the first rotation axis Rx1. That is, in the support device main body 4B having the table 5B and the base 6B, the insertion part TP, which is formed by the through-holes 5B1 and 6B1 and penetrates the support device main body 4B along the first rotation axis Rx1, is located on the first rotation axis Rx1. Here, the first rotation axis Rx1 is generally set in consideration of the weight balance of the entire projector apparatus. Since the through-holes 5B1 and 6B1 are provided on the first rotation axis Rx1, the stand SD attached to the projector 2B can be placed on the first rotation axis Rx1. Therefore, it is possible to easily maintain the weight balance of the projector apparatus 1B even after the stand SD is attached.

[0055] The support device 3B includes a table 5B, a base 6B, and a connecting member 8. The base 6B is connected to the table 5B so as to be rotatable relative to the table 5B about a first rotation axis Rx1 that is perpendicular to the installation surface on which the table 5B can be installed. The connecting member 8 corresponds to a connecting portion. The connecting member 8 is erected from the base 6B and is configured so that the projector 2B having a stand mounting portion 24B1 to which the stand SD can be mounted can be connected. The table 5B has a through-hole 5B1 that penetrates the table 5B along the first rotation axis Rx1 and through which the stand SD attached to the stand attachment part 24B1 can be inserted in the ±Y directions along the first rotation axis Rx1. The base 6B has a through-hole 6B1 that penetrates the base 6B along the first rotation axis Rx1 and through which the stand SD attached to the stand attachment part 24B1 can be inserted in the ±Y directions along the first rotation axis Rx1. According to this configuration, it is possible to achieve the same effects as the projector device 1B described above.

[0056] [Third embodiment] Next, a third embodiment of the present disclosure will be described. The stand-equipped projector device according to this embodiment has the same configuration as the stand-equipped projector devices SP1 and SP2 according to the first and second embodiments. However, the stand-equipped projector device according to this embodiment differs from the stand-equipped projector devices SP1 and SP2 according to the first and second embodiments in that the stand can be attached to the projector device by rotating the support device relative to the projector and exposing a stand attachment section provided on the projector. In the following explanation, parts that are the same or approximately the same as parts already explained will be assigned the same reference numerals and explanations thereof will be omitted.

[0057] [Projector device with stand and schematic configuration of projector device] FIG. 11 is a perspective view showing a projector device 1C of a stand-equipped projector device SP3 according to this embodiment. The stand-equipped projector device SP3 of this embodiment includes the projector device 1C shown in FIG. 11 and a stand SD not shown in FIG. 11, and functions in the same manner as the stand-equipped projector devices SP1 and SP2 of the first and second embodiments. The stand SD is detachably attached to the projector 1C. In this embodiment, the stand SD is attached to the projector 2C that constitutes the projector 1C. The projector device 1C includes a projector 2C and a support device 3C that supports the projector 2C, and has the same functions as the projector devices 1A and 1B according to the first and second embodiments.

[0058] [Projector configuration] Like the projectors 2A and 2B according to the first and second embodiments, the projector 2C projects image light from a projection opening 211 provided on the front surface 21. The projector 2C is connected to a connecting member 8 of the support device 3C. The projector 2C has the same configuration and functions as the projectors 2A and 2B according to the first and second embodiments, except that it has a bottom surface 24C instead of the bottom surface 24. That is, the projector 2C is connected to the connecting member 8 of the support device 3C on the left side surface 25 and the right side surface 26 so as to be relatively rotatable around the second rotation axis Rx2. Like the projector 2B, the projector 2C has a stand mounting portion 24B1 that has a receiving surface 24B2 and a stand fixing portion 24B3. The stand mounting portion 24B1 is provided on the bottom surface 24C, and the stand SD is mounted to the stand mounting portion 24B1. The position of the stand attachment portion 24B1 on the bottom surface 24C will be described in detail later.

[0059] [Support device configuration] The support device 3C includes a support device body 4C having a table 5C and a base 6C, and a connecting member 8 provided on the base 6C. The stand device main body 4C has the same configuration as the stand device main body 4A according to the first embodiment or the stand device main body 4B according to the second embodiment. Alternatively, the stand device main body 4C has the same configuration as the stand device main body 4B without the insertion part TP. The table 5C and base 6C constituting the stand device main body 4C have any one of the following configurations: the same configuration as the table 5A and base 6A according to the first embodiment; the same configuration as the table 5B and base 6B according to the second embodiment; and the same configuration as the table 5B and base 6B without the through-holes 5B1, 6B1. Note that when the table 5C has the same configuration as the table 5A and the base 6C has the same configuration as the base 6A, the stand device main body 4C includes a support member 7.

[0060] The support device main body 4C can rotate around the second rotation axis Rx2 by the connecting member 8. Therefore, as shown in Fig. 11, the support device main body 4C can be disposed in a position in the -Z direction, which is the opposite side to the image light projection side, with respect to the projector 2C. In other words, the table 5C and the base 6C can be disposed in a position in the -Z direction with respect to the projector 2C. In this case, the stand attachment portion 24B1 provided on the bottom surface 24C is exposed in the -Y direction. This allows the stand device main body 4C to be retracted so that the stand device main body 4C does not interfere with the attachment of the stand SD to the stand attachment portion 24B1.

[0061] [Stand attachment point location on the bottom of the projector] In the projector 2C, the stand mounting portion 24B1 is located in the -Z direction from the intersection with the first rotation axis Rx1 on the bottom surface 24C. More specifically, the stand mounting portion 24B1 is located in the -Z direction from the intersection with the first rotation axis Rx1 and the bottom surface 24C when the bottom surface 24C faces the -Y direction and the stand device main body 4C is arranged so that the first surface 51 on the table 5C opposite to the projector 2C faces the -Y direction. For this reason, the stand fixation portion 24B3 is provided in the -Z direction relative to the first rotation axis Rx1. That is, when viewed from a position facing the bottom surface 24C, the center of the stand mounting portion 24B1 is provided in the -Z direction relative to the intersection with the first rotation axis Rx1 on the bottom surface 24C. The -Z direction is the direction in which the table 5C and base 6C of the support device main body 4C are positioned relative to the projector 2C when the stand mounting portion 24B1 is exposed in the -Y direction.

[0062] Here, when the projection direction of image light by the projector 2C is changed by rotating the base 6C about the first rotation axis Rx1 relative to the table 5C before the support device body 4C is retracted in the -Z direction, it is preferable that the center of gravity of the projector 1C is located on the first rotation axis Rx1. On the other hand, when the support device body 4C is retracted in the -Z direction relative to the projector 2C, the center of gravity of the projector 1C is located further in the -Z direction than the center of gravity of the projector 1C before the support device body 4C was retracted in the -Z direction. Therefore, the position of the stand mounting part 24B1 to which the stand SD is attached is located in the -Z direction further than the position of the first rotation axis Rx1 before the support device main body 4C is retracted in the -Z direction. This makes it easier to align the position of the stand mounting part 24B1 with the center of gravity of the projector 1C in the state where the support device main body 4C is retracted in the -Z direction. Therefore, the projector 1C can be stably supported by the stand SD.

[0063] [Effects of the third embodiment] The stand-equipped projector SP3 according to this embodiment described above has the following advantages. The projector device 1C includes a projector 2C, a table 5C, a base 6C, and a connecting member 8. The projector 2C has a stand mounting portion 24B1 to which the stand SD can be mounted. The projector 2C is connected to a connecting member 8. The base 6C is connected to the table 5C so as to be rotatable relative to the table 5C about a first rotation axis Rx1 that is perpendicular to an installation surface on which the table 5C can be installed. The connecting member 8 corresponds to a connecting portion and stands upright on the base 6C. The connecting member 8 has hinges 8L1 and 8R1 that enable the projector 2C to rotate about a second rotation axis Rx2 that is perpendicular to an axis parallel to the first rotation axis Rx1. The table 5C and the base 6C are rotatable about the second rotation axis Rx2 to a position where the stand mounting portion 24B1 can be exposed toward the installation surface. That is, the table 5C and the base 6C are rotatable about the second rotation axis Rx2 to a position where the stand mounting portion 24B1 can be exposed toward the installation surface and in the -Z direction different from the projection direction of the image light with respect to the projector 2C.

[0064] According to this configuration, the stand mounting portion 24B1 of the projector 2C can be exposed in the -Y direction by rotating the table 5C and the base 6C around the second rotation axis Rx2 using the hinges 8L1 and 8R1 of the connecting member 8. Therefore, the stand SD can be mounted on the stand mounting portion 24B1 without interfering with the table 5C and the base 6C. Therefore, the stand SD can be easily mounted on the projector 1C. Furthermore, since the stand SD is attached to the stand attachment portion 24B1 provided on the projector 2C, it is possible to prevent the projector 2C from shaking in the projector device 1C to which the stand SD is attached, compared to when the stand SD is attached to the table 5B. Therefore, it is possible to prevent the image projected by the projector 2C from shaking.

[0065] In the projector device 1C, the center of the stand mounting portion 24B1 is located in the -Z direction, which is the position of the table 5C and the base 6C relative to the projector 2C when the stand mounting portion 24B1 is exposed toward the installation surface, rather than the first rotation axis Rx1. As described above, the first rotation axis Rx1 is generally set in consideration of the weight balance of the entire projector apparatus. On the other hand, when the table 5C and the base 6C are rotated about the second rotation axis Rx2 to expose the stand mounting portion 24B1, the center of gravity of the projector apparatus 1C moves in the -Z direction where the table 5C and the base 6C are located relative to the projector 2C. In contrast to this, by positioning the center of the stand mounting portion 24B1 in the −Z direction with respect to the first rotation axis Rx1, it is possible to easily maintain the weight balance of the projector 1C to which the stand SD is mounted.

[0066] The support device 3C includes a table 5C, a base 6C, and a connecting member 8. The base 6C is connected to the table 5C so as to be rotatable relative to the table 5C about a first rotation axis Rx1 that is perpendicular to an installation surface on which the table 5C can be installed. The connecting member 8 corresponds to a connecting portion, and is configured to be connectable to a projector 2C that is erected from the base 6C and has a stand mounting portion 24B1 to which a stand SD can be mounted. The connecting member 8 has hinges 8L1, 8R1 that enable the projector 2C to rotate about a second rotation axis Rx2 that is perpendicular to an axis parallel to the first rotation axis Rx1. In this embodiment, the second rotation axis Rx2 is perpendicular to the first rotation axis Rx1. The table 5C and the base 6C are rotatable about the second rotation axis Rx2 to a position where the stand attachment portion 24B1 can be exposed toward the installation surface. According to this configuration, it is possible to achieve the same effects as the projector device 1C described above.

[0067] [Fourth embodiment] Next, a fourth embodiment of the present disclosure will be described. The stand-equipped projector device according to this embodiment has a similar configuration to the stand-equipped projector device SP1 according to the first embodiment, but differs in that the connecting member has a position adjustment mechanism that can adjust the position of the projector along the Y axis. Note that in the following explanation, parts that are the same or approximately the same as parts already explained will be given the same reference numerals and explanations thereof will be omitted.

[0068] [Projector device with stand and schematic configuration of projector device] FIG. 12 is a schematic diagram showing a projector device 1D of a stand-equipped projector device SP4 according to this embodiment. As shown in FIG. 12, the stand-equipped projector device SP4 of this embodiment comprises a projector device 1D and a stand SD (not shown) that can be attached to the projector device 1D, and has the same functions as the stand-equipped projector device SP1 of the first embodiment. The projector device 1D includes a projector 2A according to the first embodiment and a support device 3D that supports the projector 2A.

[0069] [Support device configuration] The support device 3D has the same configuration and functions as the stand-equipped projector SP1 according to the first embodiment, except that it has a connecting member 8D instead of the connecting member 8. That is, the support device 3D has a support device main body 4A having a table 5A, a base 6A, and a support member 7, and a connecting member 8D provided on the base 6A.

[0070] The connecting member 8D has a pair of arms 8D1 connected to each of the left side surface 25 and the right side surface 26. Of the pair of arms 8D1, one arm 8D1 stands upright from the side surface 6R of the base 6A and is connected to the right side surface 26. Although not shown, the other arm 8D1 of the pair of arms 8D1 stands upright from the side surface 6L of the base 6A and is connected to the left side surface 25. One arm 8D1 has a hinge 8R1 that allows the projector 2A to rotate about a second rotation axis Rx2 that is perpendicular to an axis parallel to the first rotation axis Rx1, and the other arm 8D1 has a hinge 8L1 that allows the projector 2A to rotate about the second rotation axis Rx2.

[0071] Each arm 8D1 has a position adjustment mechanism 8D2 that can adjust the position of the projector 2A in the ±Y directions along the first rotation axis Rx1. The position adjustment mechanism 8D2 has a first link 8D3 standing upright from the base 6A, a second link 8D4 connected to the projector 2A, and a joint 8D5. The joint 8D5 connects the first link 8D3 and the second link 8D4 so that one of the links 8D3 and 8D4 can rotate relative to the other. By using such a position adjustment mechanism 8D2, it is possible to adjust the position of the projector 2A relative to the support device main body 4A in the ±Y directions along the first rotation axis Rx1.

[0072] In this embodiment, the support device 3D includes a support device main body 4A having a table 5A, a base 6A, and a support member 7. However, the support device 3D may also include a support device main body 4B having a table 5B and a base 6B. Furthermore, the position adjustment mechanism 8D2 of each arm 8D1 of the connecting member 8D has two links 8D3, 8D4 and a joint 8D5. However, the number of links of the position adjustment mechanism 8D2 may be three or more, and the number of joints 8D5 may also be changed as appropriate. Furthermore, the position adjustment mechanism 8D2 may have multiple rods and may be a position adjustment mechanism whose overall length is adjustable. Furthermore, the second rotation axis Rx2 is perpendicular to the first rotation axis Rx1. However, it does not have to be perpendicular to the second rotation axis Rx2. In other words, the second rotation axis Rx2 only needs to be perpendicular to an axis parallel to the first rotation axis Rx1.

[0073] [Effects of the fourth embodiment] The stand-attached projector device SP4 described above can achieve the same effects as the stand-attached projector devices SP1, SP2, and SP3 according to the first to third embodiments, and also has the following effects. In the projector device 1D, a connecting member 8D as a connecting portion includes a position adjustment mechanism 8D2 that adjusts the position of the projector in the ±Y directions along the first rotation axis Rx1. According to this configuration, it is possible to adjust the projection position of the image light PL by the projector 2A, thereby improving the convenience of the projector device 1D.

[0074] [Modification of the embodiment] The present disclosure is not limited to the above-described embodiments, and modifications and improvements within the scope of achieving the object of the present disclosure are included in the present disclosure. In the first to third embodiments, the pair of arms 8L and 8R that constitute the connecting member 8 to which the projectors 2A, 2B, and 2C are connected are erected from the bases 6A, 6B, and 6C to form a connecting portion. In the fourth embodiment, the pair of arms 8D1 that constitute the connecting member 8D to which the projector 2A is connected are erected from either the base 6A or 6B to form a connecting portion. However, this is not limiting, and the pair of arms that support the projector rotatably around the second rotation axis Rx2 may be formed integrally with the base. Furthermore, the connecting member is not limited to a configuration having a pair of arms, and may be a configuration having one arm or three or more arms.

[0075] In the above embodiments, the support devices 3A, 3B, 3C, and 3D support the projectors 2A, 2B, and 2C by the connecting members 8 and 8D so that they can rotate about the second rotation axis Rx2 that is perpendicular to the Y axis along the first rotation axis Rx1. However, the present invention is not limited to this, and the connecting portion of the support device formed by the connecting member may be connected to the projector in a state where rotation about the second rotation axis Rx2 is restricted.

[0076] In the first embodiment, the protruding portion 54 protrudes inward from the through-hole 53 along the circumferential direction centered on the first rotation axis Rx1. However, this is not limiting, and a plurality of protruding portions 54 may be provided, for example, at equal intervals along the circumferential direction centered on the first rotation axis Rx1. Furthermore, the base 6A only needs to be connected to the table 5A so as to be rotatable about the first rotation axis Rx1 relative to the table 5A, and the protruding portion 54 of the table 5A does not need to be sandwiched between the base 6A and the support member 7.

[0077] In the first embodiment, the first surface 71 serving as the second receiving surface of the support member 7 is located in the +Y direction from the surface 551 of the installation portion 55 of the table 5A and in the -Y direction from the first surface 51 of the table 5A. However, this is not limiting, and the first surface 71 may coincide with an extended surface of the surface 551 of the installation portion 55 or an extended surface of the first surface 51 of the table 5A.

[0078] In the first embodiment, the surface 641 of the stand attachment portion 64 facing the -Y direction is located in the +Y direction relative to the first surface 71 serving as the second receiving surface in the support member 7. However, this is not limiting, and the surface 641 may be located in the -Y direction relative to the first surface 71. In this case, the surface 641 can be used as the second receiving surface.

[0079] In the first and second embodiments described above, the stand attachment portion 64, 24B1 is located on the first rotation axis Rx1. More specifically, the stand fixing portion 642, 24B3 is located on the first rotation axis Rx1. However, this is not limiting, and the stand attachment portion 64, 24B1 does not have to be located on the first rotation axis Rx1, and the stand fixing portion 642, 24B3 does not have to be located on the first rotation axis Rx1.

[0080] In the second embodiment, the through-hole 5B1 of the table 5B and the through-hole 6B1 of the base 6B are positioned on the first rotation axis Rx1. However, this is not limiting, and the through-holes 5B1, 6B1 do not have to be positioned on the first rotation axis Rx1. In other words, the insertion part TP of the stand device main body 4B does not have to be positioned on the first rotation axis Rx1.

[0081] In the third embodiment described above, when the stand attachment portion 24B1 provided on the bottom surface 24C of the projector 2C is exposed in the -Y direction, the support device main body 4C having the table 5C and the base 6C is arranged relative to the projector 2C in the -Z direction, which is the opposite direction to the +Z direction in which the image light is projected. However, this is not limiting, and the position of the support device main body 4C relative to the projector 2C can be changed as appropriate as long as it is possible to arrange the support device main body 4C in a position that does not block the image light. For example, the support device main body 4C may be arranged in the +Y direction or the +Z direction relative to the projector 2C.

[0082] In the third embodiment described above, the stand mounting portion 24B1 on the bottom surface 24C is arranged in the -Z direction with respect to the intersection with the first rotation axis Rx1. However, this is not limiting, and the stand mounting portion 24B1 may be arranged on the bottom surface 24C so that the stand fixing portion 24B3 is located on the first rotation axis Rx1. Furthermore, the direction in which the stand mounting portion 24B1 is located with respect to the intersection with the first rotation axis Rx1 on the bottom surface 24C can be changed depending on the position of the stand device main body 4C having the table 5C and the base 6C with respect to the projector 2C.

[0083] In the above-described embodiments, the exterior housing 20 of the projectors 2A, 2B, and 2C is configured to have a substantially rectangular parallelepiped shape. However, the present invention is not limited to this, and the projectors 2A, 2B, and 2C may each have an exterior housing in which the left side surface 25 and the right side surface 26 connected to the connecting members 8 and 8D are formed into convex curved surfaces.

[0084] In the above-described embodiments, the stand SD is a tripod having a pan head SD2 and a screw portion SD3. However, the present invention is not limited to this, and the configuration of the stand SD is not limited to the above as long as the stand SD supports the projector devices 1A, 1B, 1C, and 1D.

[0085] Summary of this disclosure A summary of this disclosure is provided below. [Appendix 1] a table having a through-hole; a base connected to the table so as to be rotatable relative to the table around a first rotation axis perpendicular to an installation surface on which the table can be installed; a connecting portion erected from the base; a projector connected to the connection portion; a stand mounting portion that is disposed on the surface of the base facing the installation surface, is located within the through-hole, and is capable of mounting a stand; A projector device characterized by:

[0086] With this configuration, the stand is attached to the stand attachment portion provided on the base. Therefore, when attaching the projector device to a tripod as a stand, it is only necessary to rotate the base relative to the tripod screw, and there is no need to rotate the table. This makes it easy to fix the stand and the projector device together. Furthermore, because the base can rotate relative to the table, there is a slight clearance between the base and the table. In contrast, the stand is attached to a stand attachment portion of the base, which is provided with a connection portion for connecting to the projector. Therefore, compared to when the stand is attached to a table, the projector can be prevented from shaking in a projector device with the stand attached. Therefore, shaking of the image projected by the projector can be prevented.

[0087] [Appendix 2] 2. The projector device according to claim 1, a protruding portion provided on the table and protruding inward of the through-hole; a first receiving surface provided on the base and disposed inside the through-hole; a support member that faces the protruding portion, is fixed to the base in a state of contact with the first receiving surface, and allows the table to rotate relatively with respect to the base; The support member exposes the stand mounting portion. A projector device characterized by: With this configuration, the table can be clamped between the base and the support member fixed to the base. This allows the table to be attached so that it can rotate relatively to the base. Furthermore, since the support member exposes the stand attachment portion, it is easy to attach the stand to the stand attachment portion.

[0088] [Appendix 3] 3. The projector device according to claim 2, a surface of the support member on the installation surface side constitutes a second receiving surface that receives the stand; The second receiving surface is located closer to the installation surface than the surface of the table that faces the installation surface. A projector device characterized by: With this configuration, the support member forms the second receiving surface, which increases the contact area between the projector and the stand, thereby preventing the projector from tilting relative to the stand. Furthermore, when the stand is attached to the second receiving surface, the stand does not interfere with the table, which prevents the stand from coming into contact with the table when the stand is attached and damaging the table.

[0089] [Appendix 4] 4. The projector device according to claim 1, the table has an installation portion that can come into contact with the installation surface, an exposed surface of the stand attachment portion that is exposed to the installation surface side is located closer to the base than an opposing surface of the installation portion that faces the installation surface in a direction along the first rotation axis; A projector device characterized by: With this configuration, when the installation section is used to install the projector device on an installation surface, it is possible to prevent the stand attachment section from coming into contact with the installation surface before the installation section does, thereby enabling the projector device to be stably installed on the installation surface.

[0090] [Appendix 5] 4. The projector device according to claim 3, the table has an installation portion that can come into contact with the installation surface, the second receiving surface is located between the surface of the table facing the installation surface and the surface of the installation unit facing the installation surface in a direction along the first rotation axis; A projector device characterized by: With this configuration, when the installation section is used to install the projector device on an installation surface, it is possible to prevent the stand attachment section from coming into contact with the installation surface before the installation section does, thereby enabling the projector device to be stably installed on the installation surface. The second receiving surface is located closer to the installation surface than the surface of the table that faces the installation surface. This makes it easier for the stand to come into contact with the second receiving surface, making it easier to attach the stand.

[0091] [Appendix 6] 6. The projector device according to claim 1, The stand mounting portion is located on the first rotation axis. A projector device characterized by: In a projector device, the first rotation axis of the table and base, which are rotatable relative to each other, is generally set in consideration of the weight balance of the entire projector device. Since the stand attachment part is provided on this first rotation axis, it is possible to easily maintain the weight balance of the projector device even after the stand is attached.

[0092] [Appendix 7] A table and a base connected to the table so as to be rotatable relative to the table around a first rotation axis perpendicular to an installation surface on which the table can be installed; a connecting portion erected from the base; a projector having a stand mounting portion on a surface facing the base, the stand mounting portion being connectable to the connecting portion; the table and the base have a through-hole that penetrates the table and the base along the first rotation axis and through which the stand attached to the stand attachment portion can be inserted in a direction along the first rotation axis; A projector device characterized by:

[0093] With this configuration, the stand can be attached to the stand attachment portion of the projector via the through-holes in the table and base. Therefore, the stand can be easily brought into contact with the stand attachment portion of the projector that constitutes the projector device, making it easy to attach the stand to the projector device. Furthermore, since the stand is attached to a stand attachment portion provided on the projector, the projector can be prevented from shaking in a projector device with a stand attached, compared to when the stand is attached to a table, and therefore shaking of the image projected by the projector can be prevented.

[0094] [Appendix 8] 8. The projector device according to claim 7, The through-hole is located on the first rotation axis. A projector device characterized by: As described above, the first rotation axis is generally set taking into consideration the weight balance of the entire projector apparatus. Since a through-hole is provided on this first rotation axis, the stand attached to the projector can be positioned on the first rotation axis. Therefore, it is possible to easily maintain the weight balance of the projector apparatus even after the stand is attached.

[0095] [Appendix 9] A table and a base connected to the table so as to be rotatable relative to the table about a first rotation axis perpendicular to an installation surface on which the table can be installed; a connecting portion erected from the base; a projector having a stand mounting portion to which a stand can be mounted, the projector being connected to the connecting portion; the connecting portion has a hinge that allows the projector to rotate around a second rotation axis that is perpendicular to an axis parallel to the first rotation axis, the table and the base are rotatable around the second rotation axis to a position where the stand mounting portion can be exposed toward the installation surface. A projector device characterized by:

[0096] With this configuration, the stand mounting portion of the projector can be exposed by rotating the table and base around the second rotation axis using the hinge of the connecting portion. This allows the stand to be mounted on the stand mounting portion without interfering with the table and base. This makes it easy to mount the stand on the projector device. Furthermore, since the stand is attached to a stand attachment portion provided on the projector, the projector can be prevented from shaking in a projector device with a stand attached, compared to when the stand is attached to a table, and therefore shaking of the image projected by the projector can be prevented.

[0097] [Appendix 10] 10. The projector device according to claim 9, a center of the stand mounting portion is located in a direction in which the table and the base are positioned relative to the projector when the stand mounting portion is exposed toward the installation surface, relative to the first rotation axis; A projector device characterized by: As described above, the first rotation axis is generally set taking into consideration the weight balance of the entire projector apparatus. On the other hand, when the table and base are rotated around the second rotation axis to expose the stand mounting portion, the center of gravity of the projector apparatus moves in the direction of the table and base relative to the projector. In contrast to this, by positioning the center of the stand mounting portion in the above-mentioned direction relative to the first rotation axis, it is possible to easily maintain the weight balance of the projector device to which the stand is mounted.

[0098] [Appendix 11] 11. The projector device according to claim 1, the projector has a first surface and a second surface located opposite each other; the connecting portion includes a pair of arms connected to the first surface and the second surface via a hinge that enables the projector to rotate around a second rotation axis that is perpendicular to an axis parallel to the first rotation axis, A projector device characterized by:

[0099] With this configuration, the projector can be rotated around a second rotation axis that is perpendicular to the axis parallel to the first rotation axis. This allows the projector to rotate around both the first rotation axis and the second rotation axis, thereby expanding the directions in which the projector can project image light and improving the convenience of the projector device.

[0100] [Appendix 12] 12. The projector device according to claim 1, the coupling portion includes a position adjustment mechanism that adjusts the position of the projector in a direction along the first rotation axis, A projector device characterized by: With this configuration, it is possible to adjust the projection position of the image light from the projector, thereby improving the convenience of the projector device.
