Description

Technical Field

[0001] The present disclosure relates to a projector device, a projector device with a bracket, and a supporting device. Background Art

[0002] Conventionally, a support stand for supporting a projector is known (for example, see Patent Document 1).

[0003] The support platform described in Patent Document 1 includes a fixed portion and a rotating portion. The fixed portion is located on the side of the rotating portion opposite the projector and rotatably supports the rotating portion. The rotating portion includes 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 portion of the rotating portion also rotates in accordance with the movement of the rotating portion.

[0004] Thus, the user can arbitrarily set the projection direction of the image light from the projector by combining the up-and-down movement of the projector and the left-and-right movement of the rotating unit.

[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 2016-27369

[0006] In recent years, the use of projectors has become diverse, and a structure capable of adjusting the height of a projector by connecting a support such as a tripod is desired. In response to this, a structure capable of mounting a support on a fixing portion is considered to be provided in the support stand described in Patent Document 1.

[0007] However, for example, when attaching the fixing portion to a tripod's mounting screws, the entire support platform must be rotated relative to the tripod, which presents a problem of difficulty in securing the support platform to the tripod. In particular, the fixing portion rotatably supports the rotating portion of the projector, which carries a relatively heavy weight. Therefore, to prevent the support platform from tipping over, the fixing portion must be relatively heavy. Consequently, it is difficult to secure the support platform, including the fixing portion, to the tripod on a mounting surface while rotating the projector integrally.

[0008] Therefore, a structure that can easily implement the mounting of the bracket is desired. Summary of the Invention

DETAILED DESCRIPTION

[0030] First embodiment

[0031] Hereinafter, a first embodiment of the present disclosure will be described with reference to the drawings.

[0032] Structure of projector device with stand

[0033] Figure 1 It is a side view showing the projector device SP1 with a stand according to the present embodiment.

[0034] like Figure 1 As shown in FIG. 1 , the projector device SP1 with a stand according to the present embodiment is configured by combining a stand SD and a projector device 1A.

[0035] The structure of the bracket

[0036] The stand SD is detachably mounted on the projector device 1A to support the projector device 1A. In this embodiment, the stand SD is a tripod that is detachably mounted on a support device 3A (described later) of the projector device 1A and includes three legs SD1, a head SD2, and a threaded portion SD3.

[0037] Each of the three leg portions SD1 is configured to be extendable and retractable.

[0038] The pan-tilt head SD2 is the portion of the stand SD that contacts and supports the supported object. The screw portion SD3 is exposed from the pan-tilt head SD2 and inserted into the supported object. In this embodiment, the pan-tilt head SD2 contacts the first surface 71 of the support member 7 (described later), and the screw portion SD3 is fixed to the stand mounting portion 64 of the base 6A (described later). This allows the stand SD to be attached to the projector device 1A.

[0039] Structure of the projector device

[0040] Figure 2 is a perspective view showing a projector device 1A, Figure 3 Is shown from Figure 2 A perspective view of the projector device 1A viewed from the opposite side.

[0041] like Figures 1 to 3 As shown, the projector device 1A includes a projector 2A that projects image light PL and a support device 3A that supports the projector 2A. The projector 2A and the support device 3A are combined and configured.

[0042] Projector structure

[0043] The projector 2A includes an exterior casing 20 that houses an image projection device (not shown).

[0044] The exterior casing 20 has a front surface 21 , a rear 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.

[0045] The front surface 21 and the back surface 22 are outer surfaces of the exterior housing 20 that face opposite sides. Image light PL projected from an image projection device (not shown) is projected outside the projector 2A through a projection port 211 provided in the front surface 21. The projection port 211 projects the image light PL in the +Z direction, which will be described later.

[0046] The top surface 23 and the bottom surface 24 are outer surfaces facing opposite sides of the outer casing 20. The top surface 23 intersects the front surface 21, the back surface 22, the left side surface 25, and the right side surface 26. The bottom surface 24 intersects the front surface 21, the back surface 22, the left side surface 25, and the right side surface 26.

[0047] The left side surface 25 and the right side surface 26 are outer surfaces facing opposite sides of the outer casing 20. The left side surface 25 is provided with an engaging portion 251 that engages with an arm 8L (described later) of the support device 3A, and the right side surface 26 is provided with an engaging portion 261 that engages with an arm 8R (described later) of the support device 3A.

[0048] Structure of the support device

[0049] The support device 3A not only rotatably supports the projector 2A but also allows the aforementioned stand SD to be attached and detached. The support device 3A includes a support device body 4A and a connecting member 8 . The support device body 4A includes a table 5A, a base 6A, and a support member 7 .

[0050] Hereinafter, three mutually perpendicular directions are referred to as the +X, +Y, and +Z directions. In this embodiment, the +Y direction is the direction perpendicularly separated from the installation surface when the projector device 1A is installed on the installation surface. That is, the XZ plane defined by the +X and +Z directions, which are perpendicular to the +Y direction, is a plane parallel to the installation surface. In other words, the direction from the worktable 5A toward the base 6A along the first rotation axis Rx1, described later, is referred to as the +Y direction.

[0051] Although not shown in the figure, the direction opposite to the +X direction is referred to as the -X direction, the direction opposite to the +Y direction is referred to as the -Y direction, and the direction opposite to the +Z direction is referred to as the -Z direction. Furthermore, the axis along the +X direction is referred to as the X axis, the axis along the +Y direction is referred to as the Y axis, and the axis along the +Z direction is referred to as the Z axis.

[0052] Workbench structure

[0053] Figure 4 It is a cross-sectional view showing the support device 3A. Figure 5 1 is an exploded perspective view showing the support device 3A viewed from the +Y direction. Figure 6 It is an exploded perspective view showing the support device 3A viewed from the -Y direction.

[0054] The work table 5A is the portion that contacts the installation surface when the projector device 1A is installed on the installation surface. The work table 5A is formed into a circular plate shape and is configured so that when the work table 5A is combined with the base 6A and the support member 7, it can rotate relative to the base 6A about the first rotation axis Rx1 along the Y axis.

[0055] like Figure 4 As shown, the table 5A has a first surface 51 facing the installation surface when the projector device 1A is installed on the installation surface, and a second surface 52 opposite to the first surface 51. The first surface 51 faces the -Y direction, and the second surface 52 faces the +Y direction.

[0056] like Figures 4 to 6 As shown, the workbench 5A further includes a through portion 53 , a protruding portion 54 , a setting portion 55 and a recessed portion 56 .

[0057] The through portion 53 is a through-hole formed in a circular shape at the center of the worktable 5A when viewed from the +Y or -Y directions, and extends through the worktable 5A along the Y axis. Specifically, the through portion 53 includes the first rotation axis Rx1 and extends through the worktable 5A along the Y axis. Within the through portion 53, not only is the bracket mounting portion 64 of the base 6A positioned from the +Y direction, but the support member 7 is also positioned from the -Y direction.

[0058] The extension 54 is a portion extending from the inner edge of the through-hole 53 toward the inside of the through-hole 53. In other words, the extension 54 is a portion extending from the inner edge of the through-hole 53 toward the center of the through-hole 53. Specifically, the extension 54 protrudes from the +Y direction portion of the inner edge of the through-hole 53 toward the center of the through-hole 53. Therefore, the through-hole 53 is a stepped hole with a larger diameter at the end edge in the -Y direction and a smaller diameter at the end edge in the +Y direction.

[0059] The installation portion 55 is provided on the first surface 51 and contacts the installation surface. That is, the -Y direction surface 551 of the installation portion 55 is an opposing surface of the installation portion 55 and is located closer to the first surface 51 in the -Y direction.

[0060] like Figure 3 as well as Figure 6 As shown, the mounting portion 55 comprises a plurality of rubber feet arranged at equal intervals on the first surface 51 in a circumferential direction centered on the first rotation axis Rx1, contacting the mounting surface. While the number of mounting portions 55 is four in this embodiment, the number of mounting portions 55 can be varied as appropriate, as long as there is at least one. Alternatively, the mounting portion 55 may be formed in a ring shape extending circumferentially around the first rotation axis Rx1.

[0061] like Figure 4 as well as Figure 5As shown, the recess 56 is a recess that is recessed from the second surface 52 in the -Y direction and is formed into an annular shape centered on the first rotation axis Rx1. When the workbench 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 workbench 5A centered on the first rotation axis Rx1. In addition, it is preferable to apply a lubricant such as grease to the sliding surface between the recess 56 and the guide portion 68. Alternatively, a slit may be provided on the surface of the guide portion 68 that is opposite to the recess 56, and the recess 56 may have a protruding piece that is inserted into the slit of the guide portion 68.

[0062] The structure of the base

[0063] like Figures 4 to 6 As shown, the base 6A is positioned relative to the worktable 5A in the +Y direction, covering the worktable 5A in the +Y direction. The base 6A is connected to the worktable 5A so as to be rotatable relative to the worktable 5A about a first rotation axis Rx1. The base 6A has a first surface 61 facing the -Y direction and a second surface 62 facing the +Y direction and opposite the first surface 61.

[0064] The first surface 61 and the second surface 62 are inclined in a direction away from the work table 5A as they approach the +Z direction and in a direction toward the work table 5A as they approach the -Z direction. However, this is not limiting, 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 work table 5A.

[0065] Furthermore, the base 6A includes an annular portion 63 , a bracket mounting portion 64 , a first protruding portion 65 , a component receiving surface 66 , a second protruding portion 67 , and a guide portion 68 .

[0066] like Figure 4 and Figure 6 As shown, the annular portion 63 is an annular portion that protrudes from the first surface 61 toward the table 5A 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.

[0067] The bracket mounting portion 64, the first protruding portion 65 and the component receiving surface 66 are provided on the inner side of the annular portion 63. Figure 4 As shown, when the table 5A and the base 6A are assembled, the bracket mounting portion 64 , the first protrusion 65 , and the component receiving surface 66 are located within the through portion 53 when viewed from the −Y direction.

[0068] The bracket mounting portion 64 is a cylindrical portion that is capable of mounting the bracket SD and protrudes from the first surface 61 in the -Y direction. That is, the bracket mounting portion 64 is arranged on the surface on the setting surface side in the base 6A. The bracket mounting portion 64 is located on the first rotation axis Rx1, and the center of the surface 641 of the bracket mounting portion 64 that faces the -Y direction intersects with the first rotation axis Rx1. The surface 641 is the surface on the setting surface side, and a bracket fixing portion 642 is provided in the center of the surface 641. The bracket SD is fixed to the bracket fixing portion 642. In this embodiment, as described above, the bracket SD is a tripod, and the bracket fixing portion 642 is fixed. Figure 1 The threaded hole of the threaded portion SD3 of the bracket SD is shown.

[0069] The first protrusion 65 protrudes from the first surface 61 in the −Y direction.

[0070] The component receiving surface 66 is provided in a region of the -Y direction surface of the first protrusion 65 that is located inside the through-portion 53 when viewed from the -Y direction. The component receiving surface 66 receives the second surface 72 in the +Y direction of the support member 7 inserted from the -Y direction into the through-portion 53. A component securing portion 661 for securing the support member 7 is provided on the component receiving surface 66.

[0071] The fixing piece Fx for fixing the support member 7 is fixed to the component fixing portion 661, thereby fixing the support member 7 to the component fixing portion 661 while the support member 7 is in contact with the component receiving surface 66. In this embodiment, the fixing piece Fx is a screw, and the component fixing portion 661 is a threaded hole into which the distal end of the fixing piece Fx inserted through the support member 7 is inserted.

[0072] like Figure 4 as well as Figure 6 As shown, the second protrusion 67 protrudes annularly from the first surface 61 along the circumferential direction centered on the first rotation axis Rx1 at a position outside the through-portion 53 when viewed in the -Y direction. Specifically, the second protrusion 67 protrudes from the first surface 61 in the -Y direction in correspondence with the recess 56 provided in the table 5A along the circumferential direction centered on the first rotation axis Rx1.

[0073] A plurality of guide portions 68 are provided on the end surface 671 in the -Y direction of the second protruding portion 67. That is, the plurality of guide portions 68 are provided on the end surface 671 at positions spaced evenly apart in the circumferential direction around the first rotation axis Rx1. Figure 4 As shown, when the table 5A and base 6A are combined, the plurality of guides 68 are inserted from the +Y direction into the recess 56. The recess 56 and the guides 68 guide the relative rotation of the table 5A or base 6A about the first rotation axis Rx1.

[0074] Structure of supporting components

[0075] The support member 7 is formed into a circular plate shape and is inserted into the inner side of the through-portion 53 of the worktable 5A from the -Y direction. The support member 7 is opposite the extension portion 54 and is fixed to the base 6A in contact with the component receiving surface 66, enabling relative rotation of the worktable 5A relative to the base 6A. Specifically, the support member 7 is fixed to the component fixing portion 661 of the base 6A. In addition to supporting the worktable 5A together with the base 6A, the support member 7 also forms a support receiving surface for receiving the pan / tilt stage SD2 of the support SD attached to the support mounting portion 64 described above.

[0076] like Figures 4 to 6 As shown, the support member 7 has a first surface 71 facing the −Y direction and a second surface 72 facing the +Y direction and opposite to the first surface 71 , as well as a through hole 73 , a flange portion 74 , and a plurality of insertion holes 75 .

[0077] The through-hole 73 is provided in a circular shape at the center of the support member 7 when viewed from the -Y direction or the +Y direction, extending through the support member 7 from the first surface 71 toward the second surface 72. That is, the through-hole 73 extends through the support member 7 along the Y-axis. The cylindrical bracket mounting portion 64 is inserted into the through-hole 73 from the +Y direction. That is, when the worktable 5A, the base 6A, and the support member 7 are assembled, the support member 7 is exposed in the -Y direction, which serves as the mounting surface, through the through-hole 73. At this time, the first rotation axis Rx1 along the Y-axis is located within the through-hole 73.

[0078] The flange portion 74 is a portion of the support member 7 that protrudes outward from a portion of the peripheral surface 76 centered on the first rotation axis Rx1 in the -Y direction. Specifically, the flange portion 74 is a portion that protrudes radially outward from the portion of the peripheral surface 76 in the -Y direction centered on the first rotation axis Rx1 and is formed into a circular shape when viewed from the -Y direction.

[0079] When the support member 7 is disposed inside the through portion 53, the +Y-direction surface of the flange portion 74 faces the -Y-direction surface of the extension portion 54. Furthermore, when the support member 7 is disposed inside the through portion 53, the flange portion 74 and the extension portion 54 can be in contact with or separated from each other along the Y-axis.

[0080] Multiple through-holes 75 are provided around the through-hole 73. Specifically, the through-holes 75 are arranged at equal intervals outside the through-hole 73 along the circumference centered on the first rotation axis Rx1. In this embodiment, three through-holes 75 are provided, each penetrating the support member 7 along the Y-axis. The fixing member Fx is inserted into each of the through-holes 75 from the -Y direction. The fixing member Fx inserted into each through-hole 75 in the +Y direction is fixed to the member fixing portion 661, thereby fixing the support member 7 to the base 6A.

[0081] Thus, when the support member 7 is fixed to the member fixing portion 661 of the base 6A so as to sandwich the extension portion 54 of the worktable 5A between the support member 7 and the base 6A, the first surface 71 of the support member 7 functions as the second receiving surface for receiving the bracket SD. In other words, the first surface 71 of the support member 7 corresponds to the bracket receiving surface.

[0082] At this time, the first surface 71 is located closer to the +Y direction than the -Y direction surface 551 of the installation portion 55 of the work table 5A, and closer to the -Y direction than the first surface 51 of the work table 5A, along the Y axis along which the first rotation axis Rx1 extends. In other words, the first surface 71, which corresponds to the second receiving surface, is located between the first surface 51 on the installation surface side of the work table 5A and the surface 551 on the installation surface side of the installation portion 55, along the direction along the first rotation axis Rx1.

[0083] Furthermore, in the direction along the first rotation axis Rx1, the surface 641 of the bracket mounting portion 64 disposed within the through-hole 73 of the support member 7, which is exposed toward the installation surface, is located closer to the base 6A than the surface 551 of the installation portion 55, which faces the installation surface. Specifically, in the direction along the first rotation axis Rx1, the surface 641 of the bracket mounting portion 64, which faces the -Y direction, is located closer to the +Y direction than the surface 551 of the installation portion 55, which faces the -Y direction. Furthermore, the surface 641 corresponds to the exposed surface of the bracket mounting portion 64.

[0084] Installation of the bracket to the supporting device

[0085] When the bracket SD is mounted on the support device 3A, as described above, Figure 1 The stage SD2 of the stand SD shown is in 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 mounting portion 64 exposed in the -Y direction.

[0086] Structure of connecting parts

[0087] The connecting member 8 is erected from the base 6A of the support device body 4A and is connected to the projector 2A. Specifically, the connecting member 8 forms a connection portion of the base 6A that connects to the projector 2A. The connecting member 8 includes a pair of arms 8L and 8R provided at the ends of the base 6A in the +Z direction.

[0088] The arm 8L is provided on the +Z direction portion of the side surface 6L of the base 6A facing the -X direction, and is connected to the left side surface 25 of the projector 2A. The arm 8R is provided on the +Z direction portion of the side surface 6R of the base 6A facing the +X direction, and is connected to the right side surface 26 of the projector 2A. The left side surface 25 corresponds to the first surface, and the right side surface 26 corresponds to the second surface.

[0089] like Figure 5 As shown, the arm 8L has a hinge 8L1 connected to the left side 25, as shown in FIG. Figure 6 As shown, the arm 8R has a hinge 8R1 connected to the right side surface 26. The pair of arms 8L and 8R allow the projector 2A to rotate about a second rotation axis Rx2 perpendicular to an axis parallel to the first rotation axis Rx1 via the hinges 8L1 and 8R1.

[0090] Effects of the First Embodiment

[0091] The projector device SP1 with a stand according to the present embodiment described above has the following effects.

[0092] The projector device SP1 with a stand includes a projector device 1A and a stand SD. The stand SD is attached to a stand attachment portion 64 included in a support device 3A of the projector device 1A.

[0093] The projector device 1A includes a projector 2A and a support device 3A. The support device 3A includes a table 5A, a base 6A, and a connecting member 8 .

[0094] The table 5A has a through portion 53 .

[0095] 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 a mounting surface on which the table 5A can be mounted.

[0096] The connecting member 8 corresponds to a connecting portion and is provided upright from the base 6A.

[0097] The projector 2A is connected to the connection member 8 .

[0098] The base 6A has a bracket mounting portion 64 that is disposed on the first surface 61 of the base 6A and can mount a bracket. The bracket mounting portion 64 is located in the through portion 53 when the table 5A and the base 6A are combined.

[0099] With this configuration, when the projector device 1A is mounted on a tripod serving as a stand SD, the base 6A can be rotated relative to the threaded portion SD3 serving as a tripod screw without rotating the table 5A. Therefore, the stand SD and the projector device 1A can be easily fixed.

[0100] Furthermore, since the base 6A is rotatable relative to the table 5A, a slight gap exists between the base 6A and the table 5A. In contrast, since the bracket SD is attached to the bracket mounting portion 64 of the base 6A, which is provided with the connecting member 8 for connecting to the projector 2A, the projector 2A can be prevented from shaking in the projector device 1A with the bracket SD attached, compared to when the bracket SD is attached to the table 5A. Consequently, shaking of the image projected by the projector 2A can be suppressed.

[0101] The projector device 1A includes an extension portion 54 , a member receiving surface 66 , and a support member 7 .

[0102] The extension portion 54 is provided on the table 5A and extends toward the inside of the through portion 53. The component receiving surface 66 corresponds to the first receiving surface. The component receiving surface 66 is provided on the base 6A and is disposed inside the through portion 53.

[0103] The support member 7 faces the extension 54 and is fixed to the base 6A in contact with the member receiving surface 66. The support member 7 can rotate the table 5A relative to the base 6A. The support member 7 exposes the bracket mounting portion 64 in the -Y direction, which is the installation surface side.

[0104] With this structure, the worktable 5A can be clamped between the base 6A and the support member 7 fixed to the base 6A. This allows the worktable 5A to be mounted to the base 6A so that it can rotate relative to the base 6A. Furthermore, since the support member 7 exposes the bracket mounting portion 64, the bracket SD can be easily mounted to the bracket mounting portion 64.

[0105] In the projector device 1A, the first surface 71 on the installation surface side of the support member 7 serves as the receiving surface for the pan / tilt head SD2 of the stand SD. In other words, the first surface 71 serves as the second receiving surface. The first surface 71 is located closer to the installation surface side of the work table 5A than the first surface 51 on the installation surface side. Specifically, the first surface 71 is located closer to the first surface 51 in the -Y direction.

[0106] With this configuration, the first surface 71 of the support member 7 serves as a receiving surface for the stand SD, thereby increasing the contact area between the projector device 1A and the stand SD.

[0107] Furthermore, the holder SD does not interfere with the table 5A when the holder SD is mounted on the first surface 71. Therefore, it is possible to prevent the holder SD from contacting the table 5A and damaging the table 5A when the holder SD is mounted.

[0108] In the projector device 1A, the table 5A includes a mounting portion 55 capable of contacting a mounting surface. A surface 641 of the bracket mounting portion 64, exposed toward the mounting surface, serves as the exposed surface and is located closer to the base 6A than a surface 551 of the mounting portion 55 in the +Y direction along the first rotation axis Rx1. Specifically, surface 641 is located further in the +Y direction than surface 551. Furthermore, surface 551 is the opposing surface of the mounting portion 55, facing the mounting surface.

[0109] With this configuration, when the projector device 1A is installed on the installation surface via the installation portion 55, the bracket mounting portion 64 can be prevented from contacting the installation surface before the installation portion 55. Therefore, the projector device 1A can be stably installed on the installation surface.

[0110] In projector device 1A, work table 5A includes a setting portion 55 capable of contacting a setting surface. In the +Y direction along first rotation axis Rx1, first surface 71, serving as a second receiving surface, is located between first surface 51 on the setting surface side of work table 5A and surface 551 on the setting surface side of setting portion 55.

[0111] With this configuration, as described above, when the projector device 1A is installed on the installation surface using the installation portion 55, the bracket mounting portion 64 is prevented from contacting the installation surface before the installation portion 55. Therefore, the projector device 1A can be stably installed on the installation surface. Furthermore, the first surface 71 is located closer to the installation surface than the first surface 51 of the table 5A, i.e., in the -Y direction. Therefore, the pan / tilt table SD2 of the bracket SD can be easily brought into contact with the first surface 71. Therefore, the bracket SD can be easily installed on the projector device 1A.

[0112] In the projector device 1A, the stand mounting portion 64 is located on the first rotation axis Rx1.

[0113] Here, in the projector device 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 overall weight balance of the projector device 1A. Since the bracket mounting portion 64 is provided on this first rotation axis Rx1, the weight balance of the projector device 1A can be easily maintained even after the bracket SD is mounted.

[0114] In the projector device 1A, the projector 2A has a left side 25 and a right side 26 located on opposite sides of each other. One of the left side 25 and the right side 26 corresponds to the first surface, and the other corresponds to the second surface. The connecting member 8, which serves as a connecting portion, includes a pair of arms 8L and 8R. The pair of arms 8L and 8R are connected to the left side 25 and the right side 26 via hinges 8L1 and 8R1, respectively. These hinges 8L1 and 8R1 enable the projector 2A 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.

[0115] With this configuration, the projector 2A can be rotated about the second rotation axis Rx2. Thus, the projector 2A can be rotated about the first rotation axis Rx1 and about the second rotation axis Rx2, respectively. This expands the directions in which image light can be projected by the projector 2A, thereby improving the convenience of the projector device 1A.

[0116] The support device 3A includes a table 5A, a base 6A, a connecting member 8 , and a bracket mounting portion 64 .

[0117] The table 5A has a through portion 53 .

[0118] 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 a mounting surface on which the table 5A can be mounted.

[0119] The connecting member 8 constitutes a connecting portion. The connecting member 8 is erected from the base 6A and is configured to be connectable to the projector 2A.

[0120] The holder mounting portion 64 is disposed on the first surface 61 on the installation surface side of the base 6A. The holder mounting portion 64 is located within the through portion 53, and the holder SD can be mounted on the holder mounting portion 64.

[0121] According to such a configuration, the stand SD and the projector device 1A can be easily fixed.

[0122] Second embodiment

[0123] Next, a second embodiment of the present disclosure will be described.

[0124] The projector device with a stand according to this embodiment has the same structure as the projector device with a stand according to the first embodiment, but differs in that the mount SD is mounted on a projector and the support device is provided with a through portion through which the mount is inserted. In the following description, identical or substantially identical parts to those already described are denoted by the same reference numerals, and their description is omitted.

[0125] Projector device with stand and schematic structure of projector device

[0126] Figure 7 It is a side view showing the projector device SP2 with a stand according to the present embodiment. Figure 8 : is a perspective view of the projector device 1B constituting the projector device SP2 with a stand as viewed from the +Y direction. Figure 9 This is a perspective view of the projector device 1B as viewed from the −Y direction.

[0127] like Figure 7 As shown, the projector device SP2 with a stand according to this embodiment has the same structure and function as the projector device SP1 with a stand according to the first embodiment, except that it includes the projector device 1B instead of the projector device 1A. That is, the projector device SP2 with a stand includes the projector device 1B and the stand SD.

[0128] like Figures 7 to 9 As shown, 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.

[0129] Projector structure

[0130] Projector 2B has Figure 9 The projector 2B has the same structure and function as the projector 2A, except that the bottom surface 24B is shown instead of the bottom surface 24. Specifically, the projector 2B includes an exterior casing 20 having a front surface 21, a rear surface 22, a top surface 23, a bottom surface 24B, a left side 25, and a right side 26.

[0131] The bottom surface 24B is a surface facing the base 6B constituting the support device 3B.

[0132] The projector 2B further includes a stand mounting portion 24B1 .

[0133] A bracket mounting portion 24B1 is provided on the bottom surface 24B, and the bracket SD is mounted on the bracket mounting portion 24B1. In this embodiment, the bracket mounting portion 24B1 includes a receiving surface 24B2 for receiving the pan / tilt head SD2 of the bracket SD, and a bracket fixing portion 24B3 provided on the receiving surface 24B2 to fix the threaded portion SD3 of the bracket SD. The pan / tilt head SD2 contacts the receiving surface 24B2, and the threaded portion SD3 is fixed to the bracket fixing portion 24B3, thereby attaching the bracket SD to the bottom surface 24B and, in turn, to the projector 2B. In other words, in this embodiment, the bottom surface 24B serves as the first receiving surface for receiving the bracket SD.

[0134] Furthermore, the holder attachment portion 24B1 is provided on the first rotation axis Rx1 , and more specifically, the holder fixing portion 24B3 is provided on the first rotation axis Rx1 .

[0135] Structure of the support device

[0136] Figure 10 1B is a bottom view showing the projector device 1B viewed from the −Y direction.

[0137] The support device 3B supports the projector 2B so as to be rotatable about the second rotation axis Rx2, similarly to the support device 3A according to the first embodiment. The support device 3B includes a support device body 4B having Figures 7 to 10 The table 5B and the base 6B shown in FIG. 3B are provided with the connecting member 8 provided on the base 6B. In other words, the supporting device 3B according to the present embodiment does not include the supporting member 7.

[0138] Workbench structure

[0139] The work table 5B, like the work table 5A of the first embodiment, is the portion that contacts the installation surface when the projector device 1B is installed on the installation surface. The work table 5B is formed into an annular shape when viewed from the -Y direction, and is configured so that when the work table 5B is assembled with the base 6B, it can rotate relative to the base 6B about the first rotation axis Rx1.

[0140] The workbench 5B has the same structure and function as the workbench 5A except that it has a through portion 5B1 provided on the first rotation axis Rx1 instead of the through portion 53 and the protruding portion 54. Figure 9 and Figure 10 In addition to the first surface 51 , the installation portion 55 , and the through portion 5B1 , the device further includes a second surface 52 and a recessed portion 56 , which are not shown.

[0141] The through-portion 5B1 is formed into a circular shape centered on the first rotation axis Rx1 and extends through the worktable 5B along the first rotation axis Rx1. A portion of the holder SD is inserted through the through-portion 5B1 along the Y axis. Specifically, the holder SD attached to the holder mounting portion 24B1 can be inserted through the through-portion 5B1 in the ±Y directions along the first rotation axis Rx1. The diameter of the through-portion 5B1 is larger than the diameter of the through-portion 53 included in the worktable 5A according to the first embodiment.

[0142] The structure of the base

[0143] The base 6B, like the base 6A according to the first embodiment, is arranged in the +Y direction relative to the table 5B and covers the table 5B in the +Y direction. The base 6B is rotatable relative to the table 5B about the first rotation axis Rx1.

[0144] The base 6B has the same structure and function as the base 6A, except that it includes a through-portion 6B1 provided on the first rotation axis Rx1 in place of the bracket mounting portion 64, the first protrusion 65, and the component receiving surface 66. Specifically, the base 6B includes a first surface 61, a second surface 62, a second protrusion 67, a guide portion 68, and the through-portion 6B1.

[0145] The through portion 6B1 is formed into a circular shape centered on the first rotation axis Rx1 and extends through the base 6B along the first rotation axis Rx1. A portion of the holder SD is inserted through the through portion 6B1 along the Y axis. Specifically, the holder SD attached to the holder mounting portion 24B1 can be inserted through the through portion 6B1 in the ±Y directions along the first rotation axis Rx1.

[0146] When base 6B and table 5B are assembled, through-portion 6B1 connects to through-portion 5B1, forming insertion portion TP through which stent SD is inserted along the Y-axis. Specifically, support device 3B includes insertion portion TP through which stent SD is inserted along the Y-axis. Except for connecting member 8, support device 3B is annularly centered on first rotation axis Rx1.

[0147] Mounting the bracket to the projector unit

[0148] When attaching the holder SD to the projector device 1B, the holder SD is inserted from the -Y direction into the insertion portion TP. Then, with the pan / tilt head SD2 of the holder SD in contact with the receiving surface 24B2, a portion of the bottom surface 24B of the projector 2B, the threaded portion SD3 is secured to the holder fixing portion 24B3 of the holder mounting portion 24B1. This secures the holder SD to the projector 2B, and consequently, to the projector device 1B.

[0149] Effects of the Second Embodiment

[0150] The projector device SP2 with a stand according to the present embodiment described above has the following effects.

[0151] The projector device 1B includes a projector 2B and a support device 3B. The support device 3B includes a table 5B, a base 6B, and a connecting member 8 .

[0152] The workbench 5B can be installed on the installation surface.

[0153] 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.

[0154] The connecting member 8 corresponds to a connecting portion and is provided upright from the base 6B.

[0155] 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 the connecting member 8 .

[0156] The table 5B has a through-portion 5B1 extending through the table 5B along the first rotation axis Rx1. A holder SD attached to the holder mounting portion 24B1 can be inserted through the through-portion 5B1 in the ±Y directions along the first rotation axis Rx1. The base 6B has a through-portion 6B1 extending through the base 6B along the first rotation axis Rx1. A holder SD attached to the holder mounting portion 24B1 can be inserted through the through-portion 6B1 in the ±Y directions along the first rotation axis Rx1.

[0157] With this configuration, the stand SD can be attached to the stand mounting portion 24B1 of the projector 2B via the through-portions of the table 5B and the base 6B. Therefore, the stand SD can be easily brought into contact with the stand mounting portion 24B1 of the projector 2B, making it easy to attach the stand SD to the projector device 1B.

[0158] Furthermore, since the stand SD is attached to the stand mounting portion 24B1 provided on the projector 2B, shaking of the projector 2B in the projector device 1B to which the stand SD is attached can be suppressed compared to a case where the stand SD is attached to the table 5B. Consequently, shaking of the image projected by the projector 2B can be suppressed.

[0159] In the projector device 1B, the through-ports 5B1 and 6B1 are located on the first rotation axis Rx1. Specifically, in the support device body 4B having the table 5B and the base 6B, the insertion portion TP, which is formed by the through-ports 5B1 and 6B1 and extends through the support device body 4B along the first rotation axis Rx1, is located on the first rotation axis Rx1.

[0160] Here, the first rotation axis Rx1 is generally set in consideration of the overall weight balance of the projector device. Since the through-portions 5B1 and 6B1 are provided on this first rotation axis Rx1, the bracket SD attached to the projector 2B can be positioned on the first rotation axis Rx1. Therefore, even after the bracket SD is attached, the weight balance of the projector device 1B can be easily maintained.

[0161] The support device 3B includes a table 5B, a base 6B, and a connecting member 8 .

[0162] 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 a mounting surface on which the table 5B can be mounted.

[0163] The connecting member 8 corresponds to the connecting portion and is provided upright from the base 6B, and is configured to be connectable to the projector 2B having a stand mounting portion 24B1 to which the stand SD can be mounted.

[0164] The table 5B has a through-portion 5B1 extending through the table 5B along the first rotation axis Rx1. A holder SD attached to the holder mounting portion 24B1 can be inserted through the through-portion 5B1 in the ±Y directions along the first rotation axis Rx1. The base 6B has a through-portion 6B1 extending through the base 6B along the first rotation axis Rx1. A holder SD attached to the holder mounting portion 24B1 can be inserted through the through-portion 6B1 in the ±Y directions along the first rotation axis Rx1.

[0165] According to such a configuration, it is possible to achieve the same effects as those of the projector device 1B described above.

[0166] Third embodiment

[0167] Next, a third embodiment of the present disclosure will be described.

[0168] The projector device with a stand according to this embodiment has the same structure as the projector devices SP1 and SP2 with a stand according to the first and second embodiments. However, the projector device with a stand according to this embodiment differs from the projector devices SP1 and SP2 with a stand according to the first and second embodiments in that the support device is rotated relative to the projector to expose the stand mounting portion provided on the projector, thereby enabling the stand to be mounted on the projector device. In the following description, identical or substantially identical parts to those already described are denoted by the same reference numerals, and their description is omitted.

[0169] Projector device with stand and schematic structure of projector device

[0170] Figure 11 It is a perspective view showing a projector device 1C of a projector device SP3 with a stand according to the present embodiment.

[0171] The projector device SP3 with a stand according to this embodiment includes Figure 11 The projector device 1C shown and Figure 11 The stand SD not shown in the figure functions in the same manner as the projector devices SP1 and SP2 with a stand according to the first and second embodiments.

[0172] The stand SD is detachably mounted on the projector device 1C. In this embodiment, the stand SD is mounted on a projector 2C that constitutes the projector device 1C. The projector device 1C includes the 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.

[0173] Projector structure

[0174] The projector 2C, like the projectors 2A and 2B according to the first and second embodiments, projects image light from a projection port 211 provided on the front surface 21. The projector 2C is connected to the connection member 8 of the support device 3C.

[0175] The projector 2C has the same structure and function as the projectors 2A and 2B according to the first and second embodiments, except that it includes a bottom surface 24C in place of the bottom surface 24. Specifically, the projector 2C is connected to the connecting member 8 of the support device 3C at its left side 25 and right side 26 so as to be relatively rotatable about the second rotation axis Rx2.

[0176] Like the projector 2B, the projector 2C includes a stand mounting portion 24B1 having 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 on the stand mounting portion 24B1.

[0177] Note that the position of the bracket mounting portion 24B1 on the bottom surface 24C will be described in detail later.

[0178] Structure of the support device

[0179] The support device 3C includes a support device main body 4C having a table 5C and a base 6C, and a connecting member 8 provided on the base 6C.

[0180] The support device body 4C has the same structure as the support device body 4A according to the first embodiment or the support device body 4B according to the second embodiment. Alternatively, the support device body 4C has the same structure as the support device body 4B without the insertion portion TP.

[0181] The work table 5C and base 6C that constitute the support device main body 4C have any of the following structures: the same structure as the work table 5A and base 6A according to the first embodiment; the same structure as the work table 5B and base 6B according to the second embodiment; or the same structure as the work table 5B and base 6B without the through-holes 5B1 and 6B1. Furthermore, when the work table 5C has the same structure as the work table 5A and the base 6C has the same structure as the base 6A, the support device main body 4C includes a support member 7.

[0182] The supporting device body 4C can be rotated around the second rotation axis Rx2 by using the connecting member 8. Figure 11 As shown, the support device body 4C can be positioned in the -Z direction, on the opposite side of the projector 2C from the image light projection side. Specifically, the work table 5C and base 6C enable the support device body 4C to be positioned in the -Z direction relative to the projector 2C. In this case, the bracket mounting portion 24B1 provided on the bottom surface 24C is exposed in the -Y direction.

[0183] Thereby, the support device main body 4C can be retracted so that the support device main body 4C does not hinder the attachment of the stand SD to the stand attachment portion 24B1.

[0184] Position of the bracket mounting portion on the bottom surface of the projector

[0185] In the projector 2C, the bracket mounting portion 24B1 is located on the bottom surface 24C at a position closer to the -Z direction than the intersection with the first rotation axis Rx1. Specifically, the bracket mounting portion 24B1 is located closer to the -Z direction than the intersection with the first rotation axis Rx1 and the bottom surface 24C when the support device body 4C is arranged with the bottom surface 24C facing the -Y direction and the first surface 51 of the table 5C on the side opposite to the projector 2C facing the -Y direction.

[0186] Therefore, the bracket fixing portion 24B3 is located closer to the -Z direction than the first rotation axis Rx1. Specifically, when viewed from a position facing the bottom surface 24C, the center of the bracket mounting portion 24B1 is located in the -Z direction relative to the intersection of the bottom surface 24C and the first rotation axis Rx1. The -Z direction is the direction in which the table 5C and base 6C supporting the device body 4C are positioned relative to the projector 2C when the bracket mounting portion 24B1 is exposed in the -Y direction.

[0187] Here, when the base 6C is rotated relative to the table 5C about the first rotation axis Rx1 to change the projection direction of image light from the projector 2C before the support device body 4C is retracted in the -Z direction, the center of gravity of the projector device 1C is preferably 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 device 1C is located closer in the -Z direction than the center of gravity of the projector device 1C before the support device body 4C was retracted in the -Z direction.

[0188] Therefore, the position of the bracket mounting portion 24B1 of the mounting bracket SD is located in the -Z direction relative to the position of the first rotation axis Rx1 in the state before the support device main body 4C is retracted in the -Z direction. This makes it easy to align the position of the bracket mounting portion 24B1 with the center of gravity of the projector device 1C in the state after the support device main body 4C is retracted in the -Z direction. Consequently, the projector device 1C can be stably supported by the bracket SD.

[0189] Effects of the Third Embodiment

[0190] The projector device SP3 with a stand according to the present embodiment described above has the following effects.

[0191] The projector device 1C includes a projector 2C, a table 5C, a base 6C, and a connecting member 8 .

[0192] The projector 2C includes a stand mounting portion 24B1 to which the stand SD can be mounted. The projector 2C is connected to the connecting member 8 .

[0193] 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 perpendicular to a mounting surface on which the table 5C can be mounted.

[0194] The connecting member 8 corresponds to a connecting portion and is provided upright from the base 6C. The connecting member 8 includes hinges 8L1 and 8R1 that allow the projector 2C to rotate about a second rotation axis Rx2 that is perpendicular to an axis parallel to the first rotation axis Rx1.

[0195] The work table 5C and the base 6C can rotate about the second rotation axis Rx2 to a position where the bracket mounting portion 24B1 is exposed toward the installation surface. In other words, the work table 5C and the base 6C can be rotated relative to the projector 2C about the second rotation axis Rx2 to a position in the -Z direction, which is different from the projection direction of the image light, so that the bracket mounting portion 24B1 is exposed toward the installation surface.

[0196] With this configuration, by rotating the table 5C and base 6C about the second rotation axis Rx2 using the hinges 8L1 and 8R1 of the connecting member 8, the stand mounting portion 24B1 of the projector 2C can be exposed in the -Y direction. Therefore, the stand SD can be mounted on the stand mounting portion 24B1 without interfering with the table 5C and base 6C. This makes it easy to mount the stand SD to the projector apparatus 1C.

[0197] Furthermore, since the stand SD is attached to the stand attachment portion 24B1 provided on the projector 2C, shaking of the projector 2C in the projector device 1C to which the stand SD is attached can be suppressed compared to a case where the stand SD is attached to the table 5C. Consequently, shaking of the image projected by the projector 2C can be suppressed.

[0198] In the projector device 1C, the center of the stand mounting portion 24B1 is located closer to the first rotation axis Rx1 in the -Z direction. The -Z direction is the -Z direction in which the table 5C and the base 6C are located relative to the projector 2C when the stand mounting portion 24B1 is exposed toward the installation surface.

[0199] As described above, the first rotation axis Rx1 is generally set in consideration of the overall weight balance of the projector device. On the other hand, when the table 5C and base 6C are rotated about the second rotation axis Rx2 to expose the bracket mounting portion 24B1, the center of gravity of the projector device 1C moves in the -Z direction, where the table 5C and base 6C are located relative to the projector 2C.

[0200] On the other hand, by positioning the center of the stand attachment portion 24B1 in the −Z direction with respect to the first rotation axis Rx1 , the weight balance of the projector device 1C to which the stand SD is attached can be easily maintained.

[0201] The support device 3C includes a table 5C, a base 6C, and a connecting member 8 .

[0202] 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 perpendicular to a mounting surface on which the table 5C can be mounted.

[0203] The connecting member 8, which serves as a connecting portion, stands upright from the base 6C and is configured to connect to the projector 2C, which has a stand mounting portion 24B1 to which a stand SD can be mounted. The connecting member 8 includes hinges 8L1 and 8R1, which enable the projector 2C to rotate about a second rotation axis Rx2 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.

[0204] The table 5C and the base 6C are rotatable about the second rotation axis Rx2 to a position where the holder attachment portion 24B1 can be exposed toward the installation surface.

[0205] According to such a configuration, it is possible to achieve the same effects as those of the projector device 1C described above.

[0206] Fourth embodiment

[0207] Next, a fourth embodiment of the present disclosure will be described.

[0208] The projector device with a stand according to this embodiment has the same structure as the projector device with a stand SP1 according to the first embodiment, but differs in that the connecting member includes a position adjustment mechanism capable of adjusting the position of the projector along the Y-axis. In the following description, parts that are identical or substantially identical to parts already described are denoted by the same reference numerals, and their description is omitted.

[0209] Projector device with stand and schematic structure of projector device

[0210] Figure 12 1 is a schematic diagram showing a projector device 1D of a projector device SP4 with a stand according to the present embodiment.

[0211] like Figure 12 As shown, the projector device SP4 with a stand according to this embodiment includes 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 projector device SP1 with a stand according to the first embodiment.

[0212] The projector device 1D includes the projector 2A according to the first embodiment and a support device 3D that supports the projector 2A.

[0213] Structure of the support device

[0214] The support device 3D has the same structure and function as the projector device with a stand SP1 according to the first embodiment, except that it includes a connecting member 8D in place of the connecting member 8. Specifically, the support device 3D includes a support device body 4A having a table 5A, a base 6A, and a support member 7; and a connecting member 8D provided on the base 6A.

[0215] The connecting member 8D includes a pair of arms 8D1 connected to the left side surface 25 and the right side surface 26, respectively. One arm 8D1 of the pair of arms 8D1 is provided upright from the side surface 6R of the base 6A and is connected to the right side surface 26. Although not shown in the figure, the other arm 8D1 of the pair of arms 8D1 is provided 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 enables 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 enables the projector 2A to rotate about the second rotation axis Rx2.

[0216] Each arm 8D1 includes a position adjustment mechanism 8D2 capable of adjusting the position of the projector 2A in the ±Y directions along the first rotation axis Rx1.

[0217] The position adjustment mechanism 8D2 includes a first link 8D3 erected from the base 6A, a second link 8D4 connected to the projector 2A, and a joint 8D5.

[0218] The joint 8D5 connects the first link 8D3 and the second link 8D4 so that the first link 8D3 and the second link 8D4 can rotate relative to one of the other.

[0219] Such a position adjustment mechanism 8D2 can adjust the position of the projector 2A relative to the support device body 4A in the ±Y directions along the first rotation axis Rx1.

[0220] In this embodiment, the support device 3D includes the support device body 4A having the table 5A, the base 6A, and the support member 7. However, the support device 3D may include the support device body 4B having the table 5B and the base 6B.

[0221] Furthermore, the position adjustment mechanism 8D2 included in each arm 8D1 of the connecting member 8D includes two connecting rods 8D3 and 8D4 and a joint 8D5. However, the number of connecting rods included in the position adjustment mechanism 8D2 may be three or more, and the number of joints 8D5 may be appropriately changed. Furthermore, the position adjustment mechanism 8D2 may include multiple rods and be capable of adjusting its overall length.

[0222] 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.

[0223] Effects of the Fourth Embodiment

[0224] The projector device SP4 with a stand described above can achieve the following effects in addition to the same effects as those of the projector devices SP1 , SP2 , and SP3 with a stand according to the first to third embodiments.

[0225] 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.

[0226] According to such a configuration, the projection position of the image light PL of the projector 2A can be adjusted, thereby improving the convenience of the projector device 1D.

[0227] Variations of the Embodiments

[0228] The present disclosure is not limited to the above-described embodiments, and modifications and improvements within the scope that can achieve the object of the present disclosure are included in the present disclosure.

[0229] In the first to third embodiments described above, a pair of arms 8L and 8R constituting the connecting member 8 connecting the projectors 2A, 2B, and 2C are erected from the bases 6A, 6B, and 6C, forming a connecting portion. In the fourth embodiment described above, a pair of arms 8D1 constituting the connecting member 8D connecting the projector 2A is erected from either base 6A or 6B, forming a connecting portion. However, this is not limiting, and a pair of arms that support the projector so that it can rotate about the second rotation axis Rx2 may be formed integrally with the base. Furthermore, the connecting member is not limited to a structure having a pair of arms, and may also have a structure having one arm or three or more arms.

[0230] In the above-described embodiments, the support devices 3A, 3B, 3C, and 3D support the projectors 2A, 2B, and 2C using the connecting members 8 and 8D so that they can rotate about the second rotation axis Rx2, which 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.

[0231] In the first embodiment, the extension portion 54 extends inwardly of the through portion 53 along the circumferential direction centered on the first rotation axis Rx1. However, the present invention is not limited thereto, and a plurality of extension portions 54 may be provided at equal intervals along the circumferential direction centered on the first rotation axis Rx1.

[0232] 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 extension portion 54 of the table 5A may not be clamped by the base 6A and the support member 7 .

[0233] In the first embodiment described above, the first surface 71, which serves as the second receiving surface, of the support member 7 is located closer in the +Y direction than the surface 551 of the installation portion 55 of the work table 5A and closer in the -Y direction than the first surface 51 of the work table 5A. However, the present invention is not limited thereto, and the first surface 71 may coincide with an extension of the surface 551 of the installation portion 55 or with an extension of the first surface 51 of the work table 5A.

[0234] In the first embodiment described above, the surface 641 of the bracket mounting portion 64 facing the -Y direction is located closer in the +Y direction than the first surface 71 of the support member 7, which serves as the second receiving surface. However, the present invention is not limited to this, and the surface 641 may be located closer in the -Y direction than the first surface 71. In this case, the surface 641 can be used as the second receiving surface.

[0235] In the first and second embodiments described above, the bracket mounting portions 64 and 24B1 are located on the first rotation axis Rx1. Specifically, the bracket fixing portions 642 and 24B3 are located on the first rotation axis Rx1. However, this is not limiting. The bracket mounting portions 64 and 24B1 do not necessarily need to be located on the first rotation axis Rx1, and the bracket fixing portions 642 and 24B3 do not necessarily need to be located on the first rotation axis Rx1.

[0236] In the second embodiment described above, the through-portion 5B1 of the table 5B and the through-portion 6B1 of the base 6B are located on the first rotation axis Rx1. However, this is not limiting; the through-portions 5B1 and 6B1 do not necessarily need to be located on the first rotation axis Rx1. In other words, the insertion portion TP of the support device body 4B does not necessarily need to be located on the first rotation axis Rx1.

[0237] In the third embodiment described above, with the bracket mounting portion 24B1 provided on the bottom surface 24C of the projector 2C exposed in the -Y direction, the support device main body 4C, including the table 5C and the base 6C, is positioned relative to the projector 2C in the -Z direction, which is opposite to the +Z direction, which is the direction in which image light is projected. However, this is not limiting. As long as the support device main body 4C can be positioned in a position that does not block image light, the position of the support device main body 4C relative to the projector 2C can be modified as appropriate. For example, the support device main body 4C may be positioned relative to the projector 2C in the +Y direction or the +Z direction.

[0238] In the third embodiment described above, the bracket mounting portion 24B1 is positioned on the bottom surface 24C in the -Z direction relative to the intersection with the first rotation axis Rx1. However, this is not limiting; the bracket mounting portion 24B1 may be positioned on the bottom surface 24C so that the bracket fixing portion 24B3 is positioned on the first rotation axis Rx1. Furthermore, the orientation of the bracket mounting portion 24B1 relative to the intersection with the first rotation axis Rx1 on the bottom surface 24C can be changed depending on the position of the support device main body 4C having the table 5C and the base 6C relative to the projector 2C.

[0239] In the above embodiments, the outer casing 20 of the projectors 2A, 2B, and 2C is formed into a substantially rectangular parallelepiped shape. However, this is not limiting. For example, the projectors 2A, 2B, and 2C may also have outer casings whose left and right sides 25 and 26 connected to the connecting members 8 and 8D are formed into convex curved surfaces.

[0240] In the above embodiments, the stand SD is a tripod having a head SD2 and a screw portion SD3. However, the present invention is not limited thereto and any stand SD that supports the projector devices 1A, 1B, 1C, and 1D is sufficient. The structure of the stand SD is not limited to the above.

[0241] Summary of the Disclosure

[0242] The following is a summary of the present disclosure.

[0243] Note 1

[0244] A projector device, characterized by comprising:

[0245] a workbench having a through portion;

[0246] a base connected to the workbench so as to be rotatable relative to the workbench about a first rotation axis, wherein the first rotation axis is perpendicular to a mounting surface on which the workbench can be mounted;

[0247] a connecting portion erected from the base;

[0248] a projector connected to the connecting portion; and

[0249] The bracket mounting portion is arranged on the surface of the base on the installation surface side and is located in the through portion, and can mount a bracket.

[0250] With this structure, the bracket is attached to a bracket mounting portion provided on the base. Therefore, when mounting the projector device on a tripod serving as a bracket, it is sufficient to simply rotate the base relative to the tripod screws, without having to rotate the workbench. This makes it easy to secure the bracket to the projector device.

[0251] Furthermore, the base can rotate relative to the table, resulting in a slight gap between the base and the table. Furthermore, since the bracket is attached to the bracket mounting portion of the base, which is provided with a connection portion to the projector, it is possible to suppress projector shake in a projector device mounted with the bracket, compared to a case where the bracket is attached to the table. Consequently, it is possible to suppress shake in the image projected by the projector.

[0252] Note 2

[0253] The projector device according to Supplementary Note 1 is characterized in that:

[0254] The projector device comprises:

[0255] an extension portion, which is provided on the workbench and extends toward the inner side of the through portion;

[0256] a first receiving surface provided on the base and disposed inside the through portion; and

[0257] A supporting member is opposed to the protruding portion and is fixed to the base in a state of contact with the first receiving surface, and is capable of rotating the workbench relative to the base.

[0258] The support member exposes the bracket mounting portion.

[0259] With this structure, the workbench can be clamped between the base and the support member fixed to the base. Thus, the workbench can be mounted to the base in a manner that allows for relative rotation. Furthermore, the support member exposes the bracket mounting portion, making it easy to mount the bracket relative to the bracket mounting portion.

[0260] Note 3

[0261] The projector device according to Supplementary Note 2 is characterized in that

[0262] The surface of the support member on the installation surface side constitutes a second receiving surface for receiving the bracket.

[0263] The second receiving surface is located closer to the installation surface than the surface of the table on the installation surface side.

[0264] According to this structure, the support member forms the second receiving surface, thereby increasing the contact area between the projector device and the stand, thereby preventing the projector device from tilting relative to the stand.

[0265] In addition, when the bracket is installed on the second receiving surface, the bracket does not interfere with the workbench. Therefore, it is possible to suppress the situation where the bracket contacts the workbench and damages the workbench when the bracket is installed.

[0266] Note 4

[0267] The projector device according to any one of Supplementary Notes 1 to 3, characterized in that:

[0268] The workbench has a setting portion capable of contacting the setting surface,

[0269] In the direction along the first rotation axis, the exposed surface of the bracket mounting portion, which is exposed toward the installation surface, is located closer to the base than the opposing surface of the installation portion, which is opposed to the installation surface.

[0270] According to this configuration, when the projector device is installed on the installation surface via the installation portion, the bracket mounting portion can be prevented from contacting the installation surface before the installation portion.

[0271] Note 5

[0272] The projector device according to Supplementary Note 3 is characterized in that:

[0273] The workbench has a setting portion capable of contacting the setting surface,

[0274] The second receiving surface is located between a surface of the table on the installation surface side and a surface of the installation portion on the installation surface side in a direction along the first rotation axis.

[0275] According to this configuration, when the projector device is installed on the installation surface via the installation portion, the bracket mounting portion can be prevented from contacting the installation surface before the installation portion.

[0276] In addition, the second receiving surface is located closer to the setting surface side than the setting surface side of the workbench. Therefore, it is easy to make the bracket contact with the second receiving surface. Therefore, it is easy to implement the installation of the bracket.

[0277] Note 6

[0278] The projector device according to any one of Supplementary Notes 1 to 5, characterized in that:

[0279] The bracket mounting portion is located on the first rotation axis.

[0280] Here, in the projector device, the first rotation axis of the table and the base that can rotate relative to each other is generally set in consideration of the overall weight balance of the projector device. Since the bracket mounting portion is provided on this first rotation axis, the weight balance of the projector device can be easily maintained even after the bracket is mounted.

[0281] Note 7

[0282] A projector device, characterized by comprising:

[0283] Workbench;

[0284] a base connected to the workbench so as to be rotatable relative to the workbench about a first rotation axis, wherein the first rotation axis is perpendicular to a mounting surface on which the workbench can be mounted;

[0285] a connecting portion erected from the base; and

[0286] The projector has a bracket mounting portion on a surface facing the base, to which a bracket can be mounted, and is connected to the connecting portion.

[0287] The table and the base have a through portion that penetrates the table and the base along the first rotation axis. The bracket mounted on the bracket mounting portion can be inserted through the through portion in a direction along the first rotation axis.

[0288] According to such a structure, the bracket can be mounted on the bracket mounting portion of the projector via the through-hole of the workbench and the base. Therefore, the bracket can be easily brought into contact with the bracket mounting portion of the projector constituting the projector device, and thus the bracket can be easily mounted on the projector device.

[0289] Furthermore, since the bracket is attached to the bracket mounting portion provided on the projector, shaking of the projector in the projector device to which the bracket is attached can be suppressed compared to a case where the bracket is attached to a workbench. Therefore, shaking of the image projected by the projector can be suppressed.

[0290] Note 8

[0291] The projector device according to Supplementary Note 7 is characterized in that:

[0292] The through portion is located on the first rotation axis.

[0293] As described above, the first rotation axis is generally set in consideration of the overall weight balance of the projector device. Since the through portion is provided on this first rotation axis, the bracket mounted on the projector can be positioned on the first rotation axis. Therefore, even after the bracket is mounted, the weight balance of the projector device can be easily maintained.

[0294] Note 9

[0295] A projector device, characterized by comprising:

[0296] Workbench;

[0297] a base connected to the workbench so as to be rotatable relative to the workbench about a first rotation axis, wherein the first rotation axis is perpendicular to a mounting surface on which the workbench can be mounted;

[0298] a connecting portion erected from the base; and

[0299] The projector has a bracket mounting portion capable of mounting a bracket and connected to the connecting portion.

[0300] The connecting portion includes 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.

[0301] The table and the base are rotatable about the second rotation axis to a position where the bracket mounting portion is exposed toward the installation surface.

[0302] With this structure, the workbench and base are rotated about the second rotation axis using the hinge of the connecting portion, exposing the bracket mounting portion of the projector. This allows the bracket to be mounted to the bracket mounting portion without interfering with the workbench or base. This makes it easy to attach the bracket to the projector device.

[0303] Furthermore, since the bracket is attached to the bracket mounting portion provided on the projector, shaking of the projector in the projector device to which the bracket is attached can be suppressed compared to a case where the bracket is attached to a workbench. Therefore, shaking of the image projected by the projector can be suppressed.

[0304] Note 10

[0305] The projector device according to Supplementary Note 9 is characterized in that

[0306] The center of the stand mounting portion is located closer to the first rotation axis than the first rotation axis, in the directions in which the table and the base are located relative to the projector when the stand mounting portion is exposed toward the installation surface.

[0307] As described above, the first rotation axis is generally set in consideration of the overall weight balance of the projector device. On the other hand, when the table and base are rotated about the second rotation axis to expose the bracket mounting portion, the center of gravity of the projector device moves in the direction in which the table and base are located relative to the projector.

[0308] On the other hand, by positioning the center of the stand mounting portion in the above-mentioned direction with respect to the first rotation axis, the weight balance of the projector device to which the stand is mounted can be easily maintained.

[0309] Note 11

[0310] The projector device according to any one of Supplementary Notes 1 to 10, characterized in that:

[0311] The projector has a first surface and a second surface located on opposite sides of each other,

[0312] The connecting portion includes a pair of arms connected to the first surface and the second surface via hinges that allow the projector to rotate around a second rotation axis that is perpendicular to an axis parallel to the first rotation axis.

[0313] With this structure, the projector can be rotated about a second rotation axis that is perpendicular to an axis parallel to the first rotation axis. Thus, the projector can be rotated about the first rotation axis and about the second rotation axis separately, thereby expanding the directions in which image light can be projected by the projector and improving the convenience of the projector device.

[0315] The projector device according to any one of Supplementary Notes 1 to 11, characterized in that:

[0316] The connecting portion includes a position adjustment mechanism that adjusts the position of the projector in a direction along the first rotation axis.
