Description

Technical Field

[0001] The utility model relates to a projector device, a projection system and a fixing device for the projector. Background Art

[0002] Conventionally, there is known a drop prevention device for preventing a projector from falling off a table (see, for example, Patent Document 1).

[0003] The anti-dropping member described in Patent Document 1 is fixed to the top plate of the table by two countersunk screws. The anti-dropping member has a hooking portion, and the projector is arranged on the top plate in a state where the lower front surface of the housing contacts the hooking portion. As a result, the lower front surface of the projector is hooked on the hooking portion, thereby preventing the projector from moving forward and falling off the table.

[0004] Patent Document 1: Japanese Patent Application Publication No. 2018-151562

[0005] However, the anti-dropping member described in Patent Document 1 does not restrict the movement of the projector in the rearward and leftward directions. Therefore, there is a problem that the projector moves on the table due to some impact. In addition, when the projector moves backward, the size of the projected image changes and the projected image is blurred. When the projector moves left and right, the projection direction and projection position of the projector's image are offset.

[0006] Therefore, a structure capable of fixing the projector on the installation surface is desired. Utility Model Content

[0038] The outer casing 3 is a casing constituting the exterior of the projector 2. The outer casing 3 includes an upper casing 3A constituting a portion in the +Y direction and a lower casing 3B constituting a portion in the -Y direction, and the upper casing 3A and the lower casing 3B are combined to form a substantially rectangular parallelepiped shape. The outer casing 3 has a front surface 31, a back surface 32, a left side surface 33, a right side surface 34, a top surface 35, and a bottom surface 36.

[0039] The front surface 31, the back surface 32, the left side surface 33 and the right side surface 34 are respectively formed by a part of the upper shell 3A and a part of the lower shell 3B. The top surface 35 is formed by the upper shell 3A, and the bottom surface 36 is formed by the lower shell 3B. In addition, the lower shell 3B has a protrusion 3B1 protruding in the -Y direction.

The back surface 32 is the outer surface of the projector 2 observed from the +X direction, and is the outer surface facing the +X direction.

[0041] The left side surface 33 and the right side surface 34 are surfaces on opposite sides of each other on the Z axis. The left side surface 33 is the outer surface of the projector 2 observed from the -Z direction, and is the outer surface facing the -Z direction. The right side surface 34 is the surface of the projector 2 observed from the +Z direction, and is the outer surface facing the +Z direction.

[0042] In addition, at the protruding portion 3B1, the surface facing the -X direction constitutes a part of the front surface 31, and the surface facing the +X direction constitutes a part of the back surface 32. At the protruding portion 3B1, the surface facing the -Z direction constitutes a part of the left side surface 33, the surface facing the +Z direction constitutes a part of the right side surface 34, and the surface facing the -Y direction constitutes the bottom surface 36.

[0043] The top surface 35 and the bottom surface 36 are surfaces located on opposite sides to each other on the Y axis.

[0044] The top surface 35 is the outer surface of the projector 2 viewed from the +Y direction, and is the outer surface facing the +Y direction. The top surface 35 has a recessed portion 351 recessed toward the bottom surface 36 and a projection port 352 provided at the bottom of the recessed portion 351. The projection port 352 is an opening through which image light projected from the projection optical device 43 described later passes.

[0045] Figure 4 It is a bottom view showing the projector 2 .

[0046] The bottom surface 36 is a surface of the projector 2 viewed from the -Y direction and faces the -Y direction. The bottom surface 36 faces the installation surface SF where the projector 2 is installed. The bottom surface 36 has a fixed leg 361 , a movable leg 362 , an introduction port 363 , and a screw hole 364 .

[0047] The fixing leg portions 361 are provided at both end portions on the front surface 31 side of the bottom surface 36 , and are in contact with the installation surface SF. Two fixing leg portions 361 are provided on the bottom surface 36 .

[0048] The movable leg portion 362 is provided at the center of the end portion on the back surface 32 side of the bottom surface 36. The movable leg portion 362 is provided so as to be able to protrude and retract in a direction perpendicular to the bottom surface 36.

[0049] The bottom surface 36 is inclined relative to the installation surface SF by protruding the movable leg portion 362 from the bottom surface 36. Thus, the projection position of the image light projected from the top surface 35 on the projection surface SC is adjusted.

[0050] The introduction port 363 introduces gas outside the outer casing 3 into the inner part of the outer casing 3 .

[0051] A plurality of screw holes 364 are provided on the bottom surface 36. Screws, which are not shown as accessories, are inserted into the plurality of screw holes 364. The accessories, which are not shown, fix the projector 2 to a desired installation surface such as a ceiling or a wall and the bottom surface 36. The plurality of screw holes 364 include four screw holes 365, four screw holes 366, and one screw hole 367.

[0052] The four screw holes 365 are screw holes corresponding to the first fitting and are screw holes conforming to the VESA (Video Electronics Standards Association) standard, for example, and are provided substantially in the center of the bottom surface 36 .

[0053] The four threaded holes 366 are threaded holes corresponding to the second fittings and are provided outside the four threaded holes 365. Two threaded holes 366A provided on the back surface 32 side of the four threaded holes 366 are respectively provided through Figure 3 The screw SR shown is used to fix the bracket 7 of the fixing device 5 described later. That is, the two threaded holes 366A are threaded holes for fixing the second accessory, and are also threaded holes for fixing the bracket 7. In addition, the threaded holes 366A for fixing the bracket 7 may not also be used as the threaded holes for fixing the second accessory, but may be provided separately from the threaded holes for fixing the second accessory. In this case, the threaded holes for fixing the second accessory are not limited to being provided on the bottom surface 36, but may also be provided on the top surface 35, etc.

[0054] A threaded hole 367 is a threaded hole for fixing a wire fitting for preventing the projector from falling.

[0055] [Internal structure of the projector]

[0056] Figure 5 2 is a diagram showing the internal structure of the projector 2 .

[0057] The projector 2 also includes an image projection unit 4 housed in the outer casing 3. Although not shown in the figure, the projector 2 includes a control device for controlling the operation of the projector 2, a cooling device for cooling a cooling object of the projector 2, and a power supply device for supplying power to electronic components of the projector 2. The control device, the cooling device, and the power supply device are housed in the outer casing 3.

[0058] [Structure of Image Transmitting Unit]

[0059] The image projection unit 4 generates an image corresponding to an image signal input from the control device, and projects the generated image. The image projection unit 4 includes a light source device 41 , an image forming device 42 , and a projection optical device 43 .

[0060] The image projection unit 4 is formed in a substantially L-shape extending from the rear surface 32 and the left surface 33 in the outer casing 3 toward the right surface 34 and then bending toward the front surface 31 at the center of the outer casing 3 .

[0061] [Structure of light source device]

[0062] The light source device 41 is arranged in the -Z direction relative to the projection optical device 43, and emits white light toward the image forming device 42. As the light source device 41, in addition to a light source device having a light emitting element and a wavelength conversion element for converting the wavelength of light emitted from the light emitting element, a light source device having a discharge light source lamp such as an ultra-high pressure mercury lamp can be exemplified.

[0063] [Structure of Image Forming Apparatus]

[0064] The image forming device 42 forms image light from the white light incident from the light source device 41. Specifically, the image forming device 42 includes a light modulating device 421 and a color combining element 422.

[0065] The light modulator 421 modulates the incident light. Three light modulators 421 are provided. The three light modulators 421 include a red light modulator 421R that modulates red light, a green light modulator 421G that modulates green light, and a blue light modulator 421B that modulates blue light. As the light modulator 421, a structure having a transmissive liquid crystal panel and a pair of polarizers sandwiching the transmissive liquid crystal panel, a structure having a reflective liquid crystal panel, or a structure having a light modulator element other than liquid crystal such as a DMD (Digital Micromirror Device) can be adopted.

[0066] The color combining element 422 combines the color lights modulated by the light modulators 421R, 421G, and 421B to form image light. In this embodiment, the color combining element 422 is formed of a cross dichroic prism, but may be formed of a plurality of dichroic mirrors, for example.

[0067] [Structure of projection optical device]

[0068] The projection optical device 43 projects the image light formed by the image forming device 42 onto the projection surface SC. The projection optical device 43 includes a lens case 431 extending in the +X direction and then in the +Z direction, an optical path changing element (not shown), and a magnifying reflection member.

[0069] The lens case 431 accommodates a plurality of lenses therein and has an incident portion 432 , a curved portion 433 , and an emitting portion 434 .

[0070] The incident portion 432 is a portion through which image light incident from the image forming device 42 in the +Z direction passes.

[0071] The curved portion 433 is a portion connecting the incident portion 432 and the emitting portion 434. Although not shown in the figure, an optical path changing element is provided inside the curved portion 433 to bend the traveling direction of the image light passing through the incident portion in the +X direction to the +Z direction.

[0072] The emitting portion 434 extends from the curved portion 433 in the -X direction. Although not shown in the figure, an amplifying reflection component is provided inside the emitting portion 434. The amplifying reflection component is an aspherical mirror that changes the traveling direction of the image light traveling in the -X direction in the emitting portion 434 to the opposite direction. The amplifying reflection component reflects and amplifies the image light reflected by the optical path changing element and passing through the emitting portion. The image light reflected by the amplifying reflection component is projected from the projection port 352 in the +X direction and the +Y direction.

[0073] [Structure of the fixing device]

[0074] Figure 6 1 is a perspective view showing the fixing device 5 viewed from the -X direction and the +Y direction, Figure 7 It is a perspective view showing the fixing device 5 viewed from the +X direction and the −Y direction.

[0075] The fixing device 5 is disposed opposite to one of the front side 31, the back side 32, the left side 33 and the right side 34 of the outer casing 3. Figure 3 As shown, the fixing device 5 is a projector fixing device that is disposed opposite to the back surface 32 and fixes the projector 2 to the installation surface SF. Figure 6 as well as Figure 7 As shown, the fixing device 5 includes a fixing member 6 and a bracket 7 , and the fixing member 6 and the bracket 7 can be connected to each other.

[0076] In the following description, the surface facing the fixing device 5 among the front surface 31 , the back surface 32 , the left side surface 33 , and the right side surface 34 is referred to as an opposing outer surface.

[0077] [Structure of the fixing member]

[0078] Figure 8 It is a perspective view showing the fixing member 6 viewed from the −X direction and the +Y direction.

[0079] The fixing member 6 is fixed to the setting surface SF. Figure 6 to Figure 8 As shown, the fixing member 6 includes a fixing member body 61 and a connecting portion 62 .

[0080] When viewed from the +Y direction, the fixture body 61 is formed in a substantially rectangular shape that is long in the Z axis, and a surface 61A in the -Y direction contacts the installation surface SF. The dimension of the fixture body 61 in the +Y direction increases toward the +Z direction.

[0081] The fixing body 61 has a recessed portion 611 , a hole portion 612 , a first limiting surface 613 , and a second limiting surface 614 .

[0082] The recessed portion 611 is recessed from the surface of the fixture body 61 in the +Y direction toward the −Y direction.

[0083] The hole 612 is provided at the approximate center of the bottom of the recess 611. A screw (not shown) for fixing the fixture 6 to the installation surface SF is inserted into the hole 612. By fixing the screw to the installation surface SF, the fixture 6 is fixed to the installation surface SF. Figure 7 As shown, the fixture 6 may be fixed to the installation surface SF by providing adhesive tape AT on the -Y direction surface 61A of the fixture body 61. Alternatively, the fixture 6 may be fixed to the installation surface SF by an adhesive instead of the adhesive tape AT.

[0084] like Figure 6 to Figure 8 As shown in FIG. 6 , the first restriction surface 613 is a surface of the fixing body 61 in the −X direction. The first restriction surface 613 faces a first opposing surface 722 of the bracket 7 described later.

[0085] The second limiting surface 614 corresponds to the limiting surface and is a surface in the +Z direction of the fixing body 61. The second limiting surface 614 faces a second opposing surface 731 of the bracket 7 described later. When the fixing body 6 and the bracket 7 are connected, an extension of the second limiting surface 614 intersects with the back surface 32.

[0086] The connection portion 62 corresponds to a first connection portion, and is connected to a connection portion 74 of the bracket 7 to be described later.

[0087] The connection portion 62 is a convex portion that protrudes from the second restriction surface 614 in the +Z direction.

[0088] When viewed from the +Y direction, the coupling portion 62 includes a columnar portion 621 formed in a substantially cylindrical shape, and a connecting portion 623 connecting the columnar portion 621 and the fixture body 61 .

[0089] The columnar portion 621 has a plurality of protrusions 622 provided on the outer peripheral surface of the columnar portion 621 .

[0090] A plurality of protrusions 622 are provided on the outer peripheral surface of the columnar portion 621 at approximately equal intervals along the circumferential direction, and extend along the Y axis. The protrusion size of the protrusion 622 from the outer peripheral surface of the columnar portion 621 increases from the end 622A of the protrusion 622 in the -Y direction toward the end 622B of the protrusion 622 in the +Y direction, and increases from the end 622B toward the end 622A. That is, the protrusion size of the protrusion 622 from the outer peripheral surface of the columnar portion 621 is the largest at the center of the protrusion 622 on the Y axis.

[0091] Therefore, the connection portion 62 has a portion where the outer diameter of the connection portion 62 decreases as it approaches the end portion 62A in the insertion direction into the connection portion 74, that is, the -Y direction. Specifically, between the end portion 62A, which is one end of the connection portion 62, and the end portion 62B, which is the other end of the connection portion 62, the outer diameter of the connection portion 62 increases from the end portion 62A toward the end portion 62B, and increases from the end portion 62B toward the end portion 62A. In addition, one of the end portions 62A and 62B corresponds to the first end portion, and the other end portion corresponds to the second end portion.

[0092] [Stand structure]

[0093] Fig. 9 1 is a plan view showing the bracket 7 viewed from the +Y direction.

[0094] The bracket 7 is installed on the projector 2. Figure 6 , Figure 7 as well as Fig. 9 As shown, the bracket 7 includes a fixing portion 71 , an extending portion 72 , a restricting portion 73 , and a connecting portion 74 .

[0095] The fixing portion 71 protrudes from the limiting portion 73 in a substantially semicircular shape in the -X direction. The fixing portion 71 is a portion disposed between the bottom surface 36 of the projector 2 and the installation surface SF and fixed to the bottom surface 36. That is, the dimension of the fixing portion 71 along the Y axis is smaller than the dimension along the Y axis between the bottom surface 36 and the fixing leg portion 361. The fixing portion 71 has a recessed portion 711 and a hole portion 712.

[0096] The recess 711 is provided at the end of the fixing portion 71 in the -X direction and is recessed in the -Y direction from the +Y direction surface of the fixing portion 71. The recess 711 is a recess for avoiding the protrusion provided on the bottom surface 36 around the screw hole 366A.

[0097] The hole 712 is a hole through which a screw SR is inserted to fix the bracket 7 to the bottom surface 36. The screw SR inserted into the hole 712 in the +Y direction is fixed to the threaded hole 366A, thereby fixing the bracket 7 to the bottom surface 36. Alternatively, the bracket 7 may be fixed to the bottom surface 36 by an adhesive tape or an adhesive.

[0098] The extension portion 72 protrudes in the −Z direction from the restriction portion 73. When the bracket 7 is fixed to the bottom surface 36 and the fixture 6 and the bracket 7 are connected, the extension portion 72 is arranged between the rear surface 32 and the fixture 6 which are opposing outer surfaces.

[0099] When the bracket 7 is fixed to the bottom surface 36 , the surface of the extending portion 72 in the −X direction is a contact surface 721 that contacts the back surface 32 . The contact surface 721 is continuous with the surface of the restricting portion 73 in the −X direction.

[0100] like Fig.11 As shown, the contact surface 721 includes a first contact surface 721A and a second contact surface 721B that clamp the fixing portion 71 on the Z axis. When the screw SR that fixes the bracket 7 to the bottom surface 36 rotates, at least one of the first contact surface 721A and the second contact surface 721B contacts the back surface 32, thereby limiting the rotation of the bracket 7 centered on the screw SR. In the present embodiment, the portion of the back surface 32 that contacts the contact surface 721 is a portion formed by the protrusion 3B1 of the lower shell 3B. However, this is not limited to this, and the contact surface 721 may also contact other portions of the back surface 32 formed by the lower shell 3B, or may contact a portion formed by the upper shell 3A.

[0101] The surface of the extending portion 72 in the +X direction is a first opposing surface 722 that is opposed to the first restricting surface 613 of the stator 6 .

[0102] The restriction portion 73 is connected to the fixing member 6 to restrict the movement of the projector 2. The restriction portion 73 has a second facing surface 731.

[0103] The second facing surface 731 is a surface in the -Z direction of the restricting portion 73. When the bracket 7 is fixed to the bottom surface 36, an extension of the second facing surface 731 intersects the back surface 32. When the fixture 6 and the bracket 7 are connected, the second facing surface 731 faces the second restricting surface 614.

[0104] The connecting portion 74 corresponds to the second connecting portion and is a recessed portion recessed in the +Z direction from the intersection of the first facing surface 722 and the second facing surface 731. The connecting portion 74 penetrates the restricting portion 73 along the Y axis. Specifically, the connecting portion 74 opens in the +Y direction, the -Y direction, and the -Z direction.

[0105] The connection part 74 has an inner shape along the outer shape of the connection part 62. Specifically, the connection part 74 has a substantially cylindrical hole portion corresponding to the shape of the columnar part 621 and a substantially square cylindrical hole portion corresponding to the shape of the connecting part 623. The connection part 62 can be inserted into such a connection part 74 along the Y axis.

[0106] [Fix the projector with a fixing device]

[0107] When the projector 2 is fixed to the installation surface SF by the fixing device 5 , first, the fixing tool 6 is fixed to the installation surface SF.

[0108] When the fixture 6 is fixed to the installation surface SF, the projector 2 with the bracket 7 mounted thereon is arranged at an arbitrary position on the installation surface SF. For example, the projector 2 of the projector device 11 and the projector 2 of the projector device 12 are arranged at a position on the installation surface SF where at least a portion of each image projected from each projector 2 onto the projection surface SC overlaps with each other, or where each image is adjacent to each other.

[0109] Next, the fixture 6 is arranged at the position where the connection part 74 of the bracket 7 is connected to the connection part 62 of the fixture 6. Specifically, the fixture 6 is arranged on the bracket 7 by inserting the connection part 62 as a convex part into the connection part 74 as a concave part in the -Y direction.

[0110] Thereafter, the fixing tool 6 is fixed to the installation surface SF using the adhesive tape AT, an adhesive, or a screw. Thus, the fixing tool 6 is fixed to the installation surface SF, and further, the projector 2 is fixed to the installation surface SF.

[0111] Here, the connection portion 74 of the bracket 7 is movable along the Y axis relative to the connection portion 62 of the fixture 6. Therefore, by moving the projector 2 disposed on the installation surface SF in the +Y direction, the connection between the fixture 6 and the bracket 7 can be released, and the projector 2 can be moved from the installation surface SF.

[0112] [Restrictions on the movement of the projector by the fixture]

[0113] Fig.10 This is a diagram for explaining a portion of the fixing device 5 that restricts the operation of the projector 2 .

[0114] use Fig.10 A description will be given of a case where, when an external force acts on the projector 2 fixed to the installation surface SF, the operation of the projector 2 is restricted by the fixing device 5 .

[0115] When the external force F1 in the +X direction acts on the projector 2, the portion of the inner surface of the connecting portion 74 of the bracket 7 facing the +X direction contacts the portion of the connecting portion 62 of the fixing member 6 facing the -X direction. In addition, the first facing surface 722 of the bracket 7 contacts the first limiting surface 613 of the fixing member 6. Thus, the movement of the projector 2 in the +X direction is restricted.

[0116] When an external force F2 in the -X direction acts on the projector 2, the inner surface of the connecting portion 74 facing the -X direction contacts the portion of the connecting portion 62 facing the +X direction. This restricts movement of the projector 2 in the -X direction.

[0117] When an external force F3 in the +Z direction acts on the projector 2 , a portion of the inner surface of the connection portion 74 facing the +Z direction contacts a portion of the connection portion 62 facing the −Z direction. This restricts movement of the projector 2 in the +Z direction.

[0118] When the external force F4 in the -Z direction acts on the projector 2, the portion of the inner surface of the connecting portion 74 facing the -Z direction contacts the portion of the connecting portion 62 facing the +Z direction. In addition, the second opposing surface 731 of the bracket 7 contacts the second limiting surface 614 of the fixing member 6. Thus, the movement of the projector 2 in the -Z direction is limited.

[0119] In this way, even when an external force in a direction perpendicular to the Y axis is applied to the projector 2 fixed to the installation surface SF by the fixing device 5 , it is possible to suppress the projector 2 from moving along the installation surface SF.

[0120] On the other hand, by moving the projector 2 to which the stand 7 is attached from the installation surface SF in the +Y direction, the connection between the fixture 6 and the stand 7 can be released, and thus the projector 2 can be moved from the installation surface SF.

[0121] [Effects of the First Embodiment]

[0122] The projection system PS of the present embodiment described above has the following effects.

[0123] The projection system PS includes a plurality of projector devices 1 , and a continuous image is formed by the projector devices 1 .

[0124] The projector device 1 includes a projector 2 , a fixing member 6 , and a bracket 7 .

[0125] The projector 2 has a front surface 31, a back surface 32, a left side surface 33, a right side surface 34, a top surface 35, and a bottom surface 36. The front surface 31 and the back surface 32 are arranged on opposite sides to each other on the X axis, the left side surface 33 and the right side surface 34 are arranged on opposite sides to each other on the Z axis, and the top surface 35 and the bottom surface 36 are arranged on opposite sides to each other on the Y axis. The front surface 31, the back surface 32, the left side surface 33, and the right side surface 34 correspond to the first surface, the second surface, the third surface, and the fourth surface. The X axis corresponds to the first axis, the Z axis corresponds to the second axis perpendicular to the first axis, and the Y axis corresponds to the third axis perpendicular to the first axis and the second axis, respectively.

[0126] The fixing member 6 is fixed to the installation surface SF intersecting the Y-axis. The fixing member 6 has a connecting portion 62 as a first connecting portion.

[0127] The bracket 7 is fixed to the projector 2 so as to face the opposing outer surface, which is one of the front surface 31, the rear surface 32, the left side surface 33, and the right side surface 34. The bracket 7 has a connecting portion 74 connected to the connecting portion 62, and the connecting portion 74 corresponds to a second connecting portion.

[0128] The fixing member 6 and the bracket 7 are connected to each other to restrict the movement of the projector 2 along the X-axis and the movement of the projector 2 along the Z-axis.

[0129] In other words, the fixing device 5 is a projector fixing device that fixes the projector 2 to the installation surface SF intersecting the Y axis. The fixing device 5 includes a fixing member 6 and a bracket 7. In addition, the projector 2 has a front surface 31 and a back surface 32 on opposite sides of each other on the X axis, a left side surface 33 and a right side surface 34 on opposite sides of each other on the Z axis, and a top surface 35 and a bottom surface 36 on opposite sides of each other on the Y axis.

[0130] The fixing member 6 is fixed to the installation surface SF, and has a connecting portion 62. The connecting portion 62 corresponds to a first connecting portion.

[0131] The bracket 7 is fixed to the projector 2 so as to face the opposing outer surface, which is one of the front surface 31, the rear surface 32, the left side surface 33, and the right side surface 34. The bracket 7 has a connecting portion 74 connected to the connecting portion 62, and the connecting portion 74 corresponds to a second connecting portion.

[0132] The fixing member 6 and the bracket 7 are connected to each other to restrict the movement of the projector 2 along the X-axis and the movement of the projector 2 along the Z-axis.

[0133] According to such a structure, even when an external force in the direction of the X-axis and an external force in the direction of the Z-axis act on the projector 2, the movement of the projector 2 can be restricted by connecting the fixing member 6 and the bracket 7 to each other. Therefore, it is possible to suppress the projector 2 from deviating from the preset fixed position, and suppress the change in the projection position of the image of the projector 2. In addition, it is possible to easily perform the alignment of the projector 2 of each projector device 1 with respect to the installation surface SF, and further, it is possible to easily align the position of the image projected from each projector 2.

[0134] In addition, in the present embodiment, the fixing member 6 and the bracket 7 are disposed opposite to the back surface 32. That is, the fixing member 6 is disposed between the projector 2 and the projection surface SC. The fixing portion 71 of the bracket 7 is disposed between the installation surface SF and the bottom surface 36, and the structure of the bracket 7 other than the fixing portion 71 is disposed between the projector 2 and the projection surface SC. Therefore, it is possible to prevent the fixing member 6 and the bracket 7 from entering the user's field of vision.

[0135] The bracket 7 can be attached to and detached from the fixing member 6 along the Y-axis.

[0136] According to such a configuration, by moving the projector 2 along the Y axis, the bracket 7 fixed to the projector 2 can be attached to and detached from the fixture 6 fixed to the installation surface SF. Therefore, by moving the projector 2 in a direction away from the fixture 6 along the Y axis, the fixing of the projector 2 by the fixture 6 can be released. In addition, by moving the projector 2 in a direction approaching the fixture 6 along the Y axis, the projector 2 can be fixed to the installation surface SF by the fixture 6. Therefore, the convenience of the projector 2 can be improved.

[0137] The bracket 7 includes a fixing portion 71 fixed to the projector 2 and a contact surface 721 that contacts the rear surface 32 as an opposing outer surface.

[0138] According to such a configuration, the force in the direction from the projector 2 toward the contact surface 721 can be received by the contact surface 721 having a relatively large area. Therefore, it is possible to suppress the force from being locally applied to the bracket 7 or the fixture 6.

[0139] The bottom surface 36 of the projector 2 faces the installation surface SF. The fixing portion 71 is fixed to the bottom surface 36 by screws SR.

[0140] With such a configuration, the bracket 7 can be firmly fixed to the projector 2 .

[0141] Furthermore, when the bracket 7 is screwed to the projector 2 , even if the rotational force of the screw SR acts on the bracket 7 , the rotation of the bracket 7 can be restricted by the contact surface 721 contacting the back surface 32 intersecting the bottom surface 36 .

[0142] When the bracket 7 is viewed from the +X direction where the contact surface 721 contacts the back surface 32 , the contact surface 721 includes a first contact surface 721A and a second contact surface 721B sandwiching the fixing portion 71 .

[0143] When the screw SR that fixes the bracket 7 to the projector 2 is installed along the Y axis or when the screw SR is loosened, a rotational force centered on the screw SR acts on the bracket 7 as the screw SR rotates.

[0144] In contrast, the first contact surface 721A and the second contact surface 721B that contact the back surface 32 are arranged to sandwich the fixing portion 71, thereby restricting the bracket 7 from rotating with the screw SR. Therefore, the screw SR can be prevented from being accidentally loosened, and the bracket can be prevented from falling off the projector.

[0145] The projector 2 has a screw hole 366A on the bottom surface 36 for fixing with a screw SR.

[0146] The screw hole 366A is a screw hole into which a screw as an accessory for fixing the projector 2 in a state where the bottom surface 36 faces upward is inserted.

[0147] According to such a configuration, the bracket 7 can be fixed to the projector 2 using the screw holes 366A provided in advance in the projector 2. Therefore, it is not necessary to provide the projector 2 with screw holes for fixing the bracket.

[0148] Of the connection portion 62 and the connection portion 74 , the connection portion 74 included in the bracket 7 is a recessed portion.

[0149] Of the connecting portion 62 and the connecting portion 74 , the connecting portion 62 included in the fixing device 6 is a convex portion that can be inserted into the connecting portion 74 .

[0150] According to such a configuration, the connection portion 62 and the connection portion 74 can be easily connected, and the connection portions 62 and 74 can be configured relatively simply.

[0151] The connection portion 62 as a convex portion has a portion where the outer diameter of the connection portion 62 decreases as it approaches an end portion 62A in the −Y direction which is the insertion direction into the connection portion 74 .

[0152] The connection portion 74 as a recessed portion has an inner shape that follows the outer shape of the connection portion 62 .

[0153] According to such a configuration, the concave shape of the connection part 74 and the convex shape of the connection part 62 make it easy to insert the connection part 62 into the connection part 74. In addition, the connection between the connection parts 62 and 74 can be made difficult to be separated, so that the projector 2 can be prevented from being displaced on the installation surface SF.

[0154] The connection part 62 as a convex part has end parts 62A and 62B located at opposite sides to each other in the insertion direction into the connection part 74 as a concave part. One of the end parts 62A and 62B corresponds to the first end part, and the other end part corresponds to the second end part.

[0155] Between the end portion 62A and the end portion 62B, the outer diameter of the connection portion 62 increases from the end portion 62A toward the end portion 62B, and increases from the end portion 62B toward the end portion 62A.

[0156] Here, when installing the fixture 6 on the installation surface SF, first, the projector 2 is installed at a predetermined position with respect to the installation surface SF, and the fixture 6 is connected to the bracket 7 provided on the installed projector 2 .

[0157] On the other hand, when the projector 2 is installed on the installation surface SF, the bracket 7 is connected to the fixture 6 fixed to the installation surface SF.

[0158] Thus, when the fixture 6 is fixed to the installation surface SF and when the bracket 7 is connected to the fixture 6 fixed to the installation surface SF, the insertion direction of the convex connection part 62 with respect to the concave connection part 74 is opposite to each other.

[0159] In contrast, the outer diameter of the connecting portion 62 increases from the end portion 62A toward the end portion 62B, and increases from the end portion 62B toward the end portion 62A. Therefore, when the fixing member 6 is set on the setting surface SF, in addition to being able to easily connect the fixing member 6 to the bracket 7, the bracket 7 can also be easily connected to the fixing member 6 fixed to the setting surface SF.

[0160] The fixing member 6 has a second limiting surface 614, an extension of which intersects with the back surface 32 as an opposing outer surface, and the connecting portion 62 is provided on the second limiting surface 614. The second limiting surface 614 is equivalent to the limiting surface of the present invention.

[0161] The bracket 7 has a second facing surface 731, and when the connecting portion 74 is connected to the connecting portion 62, the second facing surface 731 faces the second restricting surface 614. The second facing surface 731 corresponds to the facing surface of the present invention.

[0162] According to such a structure, the second limiting surface 614 and the second opposing surface 731 are opposed to each other in a direction intersecting the Y axis and along the back surface 32. That is, the second opposing surface 731 is opposed to the second limiting surface 614 in the +Z direction. Therefore, when an external force in the -Z direction acts on the projector 2, the second limiting surface 614 and the second opposing surface 731 are in contact with each other, so that the deviation of the projector 2 in the -Z direction can be suppressed.

[0163] The fixing member 6 and the bracket 7 extend respectively along the back surface 32 as the opposing outer surface.

[0164] According to such a configuration, the bracket 7 fixed to the projector 2 can be arranged at a position close to the rear surface 32 , and further, the fixture 6 connected to the bracket 7 can be arranged at a position close to the rear surface 32 .

[0165] Furthermore, the bracket 7 and the fixture 6 extend along the back surface 32 , thereby increasing the installation area of ​​the fixture 6 relative to the installation surface SF. Therefore, the deviation of the fixture 6 due to external forces in the ±X directions intersecting the back surface 32 can be suppressed, thereby suppressing the deviation of the projector 2 .

[0166] The bracket 7 has an extension portion 72 . The extension portion 72 is located between the fixing member 6 and the back surface 32 of the projector 2 and is opposite to the fixing member 6 .

[0167] According to such a configuration, when an external force in the +X direction from the projector 2 toward the fixing member 6 acts on the projector 2 , the fixing member 6 abuts against the extending portion 72 of the bracket 7 , thereby suppressing the deviation of the projector.

[0168] The projector device 1 has a plurality of fastening devices 5 .

[0169] The bracket 7 of each fixing device 5 is disposed opposite to the rear surface 32 which is one of the opposing outer surfaces. The fixing member 6 of each fixing device 5 is disposed corresponding to the plurality of brackets 7, respectively.

[0170] According to such a structure, by providing a plurality of sets of fixing members 6 and brackets 7, it is possible to further suppress the displacement of the projector 2 along the X-axis and the displacement of the projector 2 along the Z-axis. In addition, by providing a plurality of sets of fixing members 6 and brackets 7, it is possible to suppress the rotation of the projector 2 even when a rotational force centered on a rotation axis along the Y-axis acts on the projector 2.

[0171] [Second embodiment]

[0172] Next, a second embodiment of the present invention will be described.

[0173] The projection system of this embodiment has the same structure as the projection system PS of the first embodiment, but the structure of the fixing device is different. In detail, in the fixing device 5 of the first embodiment, the fixing member 6 fixed to the setting surface SF has a connecting portion 62 as a convex portion, and the bracket 7 fixed to the projector 2 has a connecting portion 74 as a concave portion. In contrast, in the fixing device of this embodiment, the fixing member has a connecting portion as a concave portion, and the bracket has a connecting portion as a convex portion. In addition, in the following description, the same reference numerals are marked for the parts that are the same or substantially the same as the parts that have been described, and the description is omitted.

[0174] Fig.11 This is a diagram showing a fixing device 5A included in the projector device 1 of the projection system according to the present embodiment as viewed from the +Y direction.

[0175] The projection system of this embodiment has a second embodiment in addition to replacing the fixing device 5 of the first embodiment. Fig.11 The projector device 1 of this embodiment has the same structure and function as the projection system PS of the first embodiment except for the fixing device 5A shown. Fig.11 The fixing device 5A is shown.

[0176] The fixing device 5A includes a fixing tool 8 fixed to the installation surface SF and a bracket 9 fixed to the projector 2 .

[0177] [Structure of the fixing member]

[0178] The fixing tool 8 has the same structure and function as the fixing tool 6 of the first embodiment, except that the fixing tool 8 has a connecting portion 82 instead of the connecting portion 62. That is, the fixing tool 8 includes a fixing tool body 61 and a connecting portion 82.

[0179] As described above, the surface of the stator body 61 in the −X direction is the first restriction surface 613 , and the surface of the stator body 61 in the +Z direction is the second restriction surface 614 .

[0180] The connecting portion 82 is equivalent to the first connecting portion. Specifically, the connecting portion 82 is a recessed portion of the fixing body 61 that is recessed from the second limiting surface 614 facing the +Z direction toward the -Z direction. The connecting portion 82 is the same recessed portion as the connecting portion 74 of the first embodiment, and penetrates the fixing body 61 along the Y axis. Specifically, the connecting portion 82 is open in the +Y direction, the -Y direction, and the +Z direction.

[0181] The connection portion 82 has an internal shape that conforms to the external shape of a connection portion 94 described later of the bracket 9. The connection portion 94 can be inserted into the connection portion 82 along the Y axis.

[0182] [Stand structure]

[0183] The bracket 9 has the same structure and function as the bracket 7 of the first embodiment except that the bracket 94 is provided instead of the connecting portion 74. That is, the bracket 9 includes the fixing portion 71, the extending portion 72, the restricting portion 73, and the connecting portion 94.

[0184] The surface of the extension portion 72 in the -X direction is a contact surface 721 that contacts the back surface 32 as the opposing outer surface. The surface of the extension portion 72 in the +X direction is a first opposing surface 722 that is opposed to the first limiting surface 613 of the fixing member 8. The surface of the limiting portion 73 in the -Z direction is a second opposing surface 731 that is opposed to the second limiting surface 614 of the fixing member 8.

[0185] The connecting portion 94 is equivalent to the second connecting portion. The connecting portion 94 is a convex portion protruding from the second opposing surface 731 in the +Z direction, and is the same convex portion as the connecting portion 62 of the first embodiment. That is, when viewed from the +Y direction, the connecting portion 94 includes: a columnar portion 621 formed in a substantially cylindrical shape; and a connecting portion 623 that connects the columnar portion 621 and the second opposing surface 731. In addition, the columnar portion 621 is provided with the above-mentioned plurality of ridges 622.

[0186] [Effects of the Second Embodiment]

[0187] The projection system of the present embodiment described above achieves the same effects as those of the projection system PS of the first embodiment.

[0188] [Variations of Embodiments]

[0189] The present invention is not limited to the above-described embodiments, and modifications and improvements within the scope that can achieve the object of the present invention are included in the present invention.

[0190] In the above embodiments, the projector device 1 includes two fixing devices 5, 5A, each of which is disposed opposite to the back surface 32 of the projector 2. However, the present invention is not limited thereto, and the number of fixing devices 5, 5A included in the projector device 1 may be one or three or more.

[0191] In the above-mentioned embodiments, the fixing devices 5 and 5A are disposed opposite to the back surface 32 of the projector 2. That is, the opposing outer surface opposing the fixing devices 5 and 5A is the back surface 32. However, the opposing outer surface opposing the fixing devices 5 and 5A is not limited to the back surface 32, and may be one of the front surface 31, the left side surface 33, and the right side surface 34. For example, in the case where the projector device 1 includes two fixing devices 5, the two fixing devices 5 may be disposed opposite to one of the front surface 31, the left side surface 33, and the right side surface 34, respectively.

[0192] Fig.12 It is a plan view of the projector device 1 showing a variation of the arrangement of the fixing device 5 .

[0193] And, for example, Fig.12 As shown in the figure, when the projector device 1 has two fixing devices 5, one fixing device 5 may be arranged opposite to the back surface 32, and the other fixing device 5 may be arranged opposite to the right side surface 34. That is, one of the two fixing devices 5 may be arranged on one of two mutually intersecting surfaces among the front surface 31, the back surface 32, the left side surface 33, and the right side surface 34, and the other fixing device 5 may be arranged on the other of the two surfaces.

[0194] In addition, for example, in the case where the projector device 1 has two fixing devices 5, one of the two fixing devices 5 may be arranged on one of two surfaces that are on opposite sides of each other among the front surface 31, the back surface 32, the left side surface 33 and the right side surface 34, and the other fixing device 5 may be arranged on the other of the two surfaces.

[0195] The same applies to the case where the fixing device 5A is used instead of the fixing device 5 .

[0196] That is, the brackets 7 and 9 may be provided on at least two surfaces of the front surface 31 , the back surface 32 , the left side surface 33 , and the right side surface 34 , respectively, and the fixing members 6 and 8 may be provided corresponding to the brackets 7 and 9 .

[0197] According to such a structure, similar to the case of providing a plurality of sets of fixing parts 6 and brackets 7, in addition to being able to further suppress the displacement of the projector 2 along the X-axis and the displacement of the projector along the Z-axis, it is also possible to suppress the rotation of the projector 2 around the rotation axis along the Y-axis.

[0198] Furthermore, the brackets 7 and 9 may be provided on one of the front surface 31 and the back surface 32 and one of the left surface 33 and the right surface 34 , respectively, and the fixing members 6 and 8 may be provided corresponding to the brackets 7 and 9 .

[0199] According to such a structure, by arranging a plurality of brackets 7, 9 and a plurality of fixing parts 6, 8 opposite to each other on the front side 31, the back side 32, the left side 33 and the right side 34, the displacement of the projector along the X-axis and the displacement of the projector along the Z-axis can be further suppressed. In addition, the rotation of the projector 2 around the rotation axis along the Y-axis can be suppressed.

[0200] In the first embodiment, the bracket 7 can be mounted and removed along the Y axis relative to the fixing member 6. In the second embodiment, the bracket 9 can be mounted and removed along the Y axis relative to the fixing member 8. However, this is not limited to this, and the direction of mounting and removing the bracket 7, 9 relative to the fixing members 6, 8 may also be a direction intersecting the Y axis.

[0201] In addition, for example, when a locking mechanism such as the following is provided, the direction of loading and unloading the bracket relative to the fixing part may also be a direction perpendicular to the Y-axis: when the projector device 1 is used, the locking mechanism restricts the movement of the projector 2 in the direction perpendicular to the Y-axis; when the projector device 1 is not used, the locking mechanism allows the projector 2 to move in the direction perpendicular to the Y-axis.

[0202] In the above-mentioned embodiments, the brackets 7 and 9 have the contact surface 721 that contacts the back surface 32 when the brackets 7 and 9 are mounted on the projector 2. That is, the brackets 7 and 9 have the contact surface 721 that contacts the opposing outer surfaces of the front surface 31, the back surface 32, the left side surface 33, and the right side surface 34 of the projector 2. However, the present invention is not limited to this, and in the case where the brackets 7 and 9 at the fixing portion 71 are firmly fixed to the projector 2, etc., there may be no contact surface 721.

[0203] In addition, protrusions such as pins and ribs may be provided on the outer shell 3 and one of the brackets 7 and 9, and recesses or holes for inserting the protrusions may be provided on one of the outer shell 3 and the brackets 7 and 9 so that the brackets 7 and 9 do not rotate relative to the outer shell 3 around the screw SR.

[0204] Furthermore, the contact surface 721 includes a first contact surface 721A and a second contact surface 721B that sandwich the fixing portion 71. However, the present invention is not limited thereto, and the contact surface 721 may be one of the first contact surface 721A and the second contact surface 721B. That is, as long as the rotation of the bracket 7 about the hole 712 can be restricted, the position of the contact surface 721 that contacts the outer surface of the projector 2 is not limited.

[0205] In the above-mentioned embodiments, the screw hole 366A for fixing the screw SR for mounting the bracket 7, 9 on the bottom surface 36 is a screw hole for fixing the accessory, and is also a screw hole for fixing the bracket 7. However, the present invention is not limited thereto, and the screw hole 366A may be a screw hole provided separately from the screw hole for fixing the accessory and provided for fixing the bracket 7. In addition, the screw hole for fixing the bracket 7, 9 may be one of the other screw holes 364, for example, one of the screw holes 365.

[0206] In addition, screw holes for mounting screws SR for fixing the brackets 7 and 9 may be provided on a surface other than the bottom surface 36 .

[0207] In the first embodiment, the connection part 62 as the first connection part is a convex part, and the connection part 74 as the second connection part is a concave part into which the convex part can be inserted. In the second embodiment, the connection part 82 as the first connection part is a concave part, and the connection part 94 as the second connection part is a convex part that can be inserted into the concave part. However, this is not limited to this, and as long as the first connection part and the second connection part are in a shape that can be connected to each other and can be separated from each other, the structure of each of the first connection part and the second connection part can be appropriately changed.

[0208] In the above-mentioned embodiments, the outer diameter of the connecting portion 62, 94 as a convex portion increases from one end portion on the Y axis toward the other end portion, and increases from the other end portion toward one end portion. In other words, the outer diameter of the connecting portion 62, 94 decreases toward one end portion on the Y axis, and decreases toward the other end portion. However, the present invention is not limited thereto, and the outer diameter of the connecting portion 62, 94 as a convex portion may be constant.

[0209] Furthermore, as long as the movement of the connecting portions 62 , 94 in the direction perpendicular to the Y axis can be restricted, the inner shape of the connecting portions 74 , 82 as recessed portions does not necessarily need to conform to the outer shape of the connecting portions 62 , 94 .

[0210] In the above-mentioned embodiments, the extension surface of the second limiting surface 614 provided with the connecting portion 62 or the connecting portion 94 intersects with the opposing outer surface, and the brackets 7 and 9 have the second opposing surface 731 opposing the second limiting surface 614. Here, even when an external force in the direction of the second limiting surface 614 acts on the projector 2, the second opposing surface 731 does not need to contact the second limiting surface 614.

[0211] In the above-mentioned embodiments, the brackets 7 and 9 are arranged between the fixing members 6 and 8 and the projector 2, and have the extension portion 72 facing the fixing members 6 and 8. However, the present invention is not limited thereto, and the extension portion 72 may not be provided. In this case, when an external force from the projector 2 in the direction toward the fixing members 6 and 8 acts on the projector 2, the movement of the projector 2 may be restricted by the contact between the opposing outer surfaces of the projector 2 and the fixing members 6 and 8.

[0212] In the above-mentioned embodiments, the brackets 7 and 9 are attached to the outer casing 3 of the projector 2 by screws SR. However, the present invention is not limited thereto, and the outer casing 3 may have the same structure as the brackets 7 and 9.

[0216] [Summary of the utility model]

[0217] Below, the summary of the present utility model is attached.

[0218] [Note 1]

[0219] A projector device, characterized in that the projector device comprises: a projector, which has a first surface and a second surface on opposite sides of each other on a first axis, a third surface and a fourth surface on opposite sides of each other on a second axis perpendicular to the first axis, and a fifth surface and a sixth surface on opposite sides of each other on a third axis perpendicular to the first axis and the second axis respectively; a fixing member, which is fixed to a setting surface intersecting the third axis and has a first connecting portion; and a bracket, which is fixed to the projector facing one of the first surface, the second surface, the third surface and the fourth surface, and has a second connecting portion connected to the first connecting portion, the fixing member and the bracket are connected to each other to limit the movement of the projector along the first axis and the movement of the projector along the second axis.

[0220] According to such a structure, even when a force along the first axis and a force along the second axis act on the projector, the movement of the projector can be restricted by connecting the fixing member and the bracket to each other. Therefore, the projector can be prevented from deviating from a preset fixed position, and the projection position of the image of the projector can be prevented from changing.

[0221] [Note 2]

[0222] The projector device according to Supplementary Note 1 is characterized in that the bracket can be loaded and unloaded relative to the fixing member along the third axis.

[0223] According to such a structure, by moving the projector along the third axis, the bracket fixed to the projector can be attached and detached relative to the fixing part fixed to the installation surface. Therefore, by moving the projector in a direction away from the fixing part along the third axis, the fixing of the projector by the fixing part can be released. In addition, by moving the projector in a direction approaching the fixing part along the third axis, the projector can be fixed to the installation surface by the fixing part. Therefore, the convenience of the projector can be improved.

[0224] [Note 3]

[0225] The projector device according to Supplementary Note 1 or 2 is characterized in that the bracket has: a fixing portion fixed to the projector; and a contact surface that contacts the one surface.

[0226] According to such a configuration, the force in the direction from the projector toward the contact surface can be received by the contact surface having a relatively large area, so that it is possible to suppress the force from being locally applied to the bracket or the fixture.

[0227] [Note 4]

[0228] The projector device according to Supplementary Note 3 is characterized in that the sixth surface is opposite to the installation surface, and the fixing portion is fixed to the sixth surface by a screw.

[0229] According to such a structure, the bracket can be firmly fixed to the projector.

[0230] Furthermore, when the bracket is screwed to the projector, even if the rotational force of the screw acts on the bracket, the rotation of the bracket can be restricted by the contact surface coming into contact with the one surface intersecting the sixth surface.

[0231] [Note 5]

[0232] The projector device according to Supplementary Note 4 is characterized in that when the bracket is viewed from a direction in which the contact surface contacts the one surface, the contact surface includes a first contact surface and a second contact surface sandwiching the fixing portion.

[0233] When a screw that fixes the bracket to the projector is installed along the third axis or when the screw is loosened, a rotational force centered on the screw acts on the bracket as the screw rotates.

[0234] On the other hand, by arranging the first contact surface and the second contact surface that contact the one surface to sandwich the fixing portion, the bracket can be restricted from rotating with the rotation of the screw, thereby preventing the screw from accidentally loosening and preventing the bracket from falling off the projector.

[0235] [Note 6]

[0236] The projector device according to Appendix 4 or 5 is characterized in that the projector has a threaded hole on the sixth surface for fixing the screw, and the threaded hole is a threaded hole for inserting a screw as an accessory for fixing the projector in a state where the sixth surface faces upward.

[0237] According to such a configuration, the bracket can be fixed to the projector using the screw holes previously provided in the projector. Therefore, it is not necessary to provide the projector with screw holes for fixing the bracket.

[0238] [Note 7]

[0239] The projector device according to any one of Supplementary Notes 1 to 6 is characterized in that one of the first connecting portion and the second connecting portion is a recessed portion, and the other of the first connecting portion and the second connecting portion is a convex portion that can be inserted into the recessed portion.

[0240] According to such a configuration, the first connection portion and the second connection portion can be easily connected to each other, and the first connection portion and the second connection portion can be configured relatively simply.

[0241] [Note 8]

[0242] The projector device according to Note 7 is characterized in that the other connecting part has a portion where the outer diameter of the other connecting part becomes smaller as it approaches the end of the insertion direction into the one connecting part, and the one connecting part has an internal shape along the external shape of the other connecting part.

[0243] According to such a structure, the concave shape of one connecting part and the convex shape of another connecting part can easily insert the other connecting part into one connecting part. In addition, the connection between the first connecting part and the second connecting part can be made difficult to be separated, so the deviation of the projector on the installation surface can be suppressed.

[0244] [Note 9]

[0245] The projector device according to Note 8 is characterized in that the other connecting part has a first end and a second end located on opposite sides of each other in an insertion direction into the one connecting part, and between the first end and the second end, the outer diameter of the other connecting part increases from the first end toward the second end, and increases from the second end toward the first end.

[0246] Here, when installing the fixing tool on the installation surface, first, the projector is installed at a predetermined position with respect to the installation surface, and the fixing tool is connected to a bracket provided on the installed projector.

[0247] On the other hand, the projector is placed on the installation surface by connecting the bracket to a fixture fixed to the installation surface.

[0248] Thus, when the fixing tool is fixed to the installation surface and when the bracket is connected to the fixing tool fixed to the installation surface, the insertion direction of the other connecting portion with respect to the one connecting portion as the recessed portion is opposite to each other.

[0249] In contrast, the outer diameter of the other connecting portion increases from the first end toward the second end, and increases from the second end toward the first end. Therefore, when a fixing member is set on the setting surface, in addition to being able to easily connect the fixing member to the bracket, the bracket can also be easily connected to the fixing member fixed on the setting surface.

[0250] [Note 10]

[0251] The projector device according to Note 8 or Note 9 is characterized in that the fixing part has a limiting surface, an extension surface of which intersects with the one surface, the first connecting part is arranged on the limiting surface, and the bracket has an opposing surface, which is opposite to the limiting surface when the second connecting part is connected to the first connecting part.

[0252] According to such a structure, the limiting surface and the opposing surface are opposed to each other in a direction intersecting the third axis and along the above-mentioned one surface. Therefore, when an external force in the direction of the opposing surface toward the limiting surface acts on the projector, the limiting surface and the opposing surface contact each other, which can suppress the deviation of the projector.

[0253] [Note 11]

[0254] The projector device according to any one of Notes 7 to 10 is characterized in that the fixing member and the bracket extend along the one surface respectively.

[0255] According to such a configuration, the bracket fixed to the projector can be arranged at a position close to the one surface of the projector, and further, the fixing tool connected to the bracket can be arranged at a position close to the one surface.

[0256] Furthermore, the bracket and the fixing member extend along the one surface, thereby increasing the installation area of ​​the fixing member relative to the installation surface, thereby suppressing the displacement of the fixing member with respect to the force in the direction intersecting the one surface, and further suppressing the displacement of the projector.

[0257] [Note 12]

[0258] The projector device according to Supplementary Note 11 is characterized in that the bracket has an extension portion, and the extension portion is located between the fixing member and the projector and is opposite to the fixing member.

[0259] According to such a configuration, when an external force in a direction from the projector toward the fixing member acts on the projector, the fixing member abuts against the extending portion of the bracket, thereby suppressing deviation of the projector.

[0260] [Note 13]

[0261] The projector device according to any one of Notes 1 to 12 is characterized in that a plurality of the brackets are arranged opposite to the one surface, and a plurality of the fixing members are respectively arranged corresponding to the plurality of the brackets.

[0262] According to such a structure, by providing a plurality of sets of fixing parts and brackets, it is possible to further suppress the deviation of the projector along the first axis and the deviation of the projector along the second axis. In addition, by providing a plurality of sets of fixing parts and brackets, it is possible to suppress the rotation of the projector even when a rotational force centered on the rotation axis along the third axis acts on the projector.

[0263] [Note 14]

[0264] The projector device according to any one of Notes 1 to 12 is characterized in that the bracket is respectively arranged on at least two of the first surface, the second surface, the third surface and the fourth surface, and the fixing member is arranged corresponding to the bracket.

[0265] According to such a configuration, similarly to the projector of Supplementary Note 13, in addition to being able to further suppress the deviation of the projector along the first axis and the deviation of the projector along the second axis, it is also possible to suppress the rotation of the projector.

[0266] [Note 15]

[0267] The projector device according to Appendix 14 is characterized in that the bracket is respectively arranged on one of the first surface and the second surface, and one of the third surface and the fourth surface, and the fixing member is arranged corresponding to the bracket.

[0268] According to such a structure, one of the first and second surfaces and one of the third and fourth surfaces are intersecting surfaces. Therefore, by configuring multiple brackets and multiple fixings opposite to the mutually intersecting surfaces, the offset of the projector along the first axis and the offset of the projector along the second axis can be further suppressed. In addition, the rotation of the projector around the rotation axis along the third axis can be suppressed.
