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 fall prevention tool for preventing a projector from falling off a table (see, for example, Patent Document 1).

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

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

[0005] However, the drop prevention 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 for the image are offset.

[0006] Therefore, it is desirable to increase a structure that can limit the direction in which the projector moves on the installation surface. Utility Model Content

In this embodiment, the projector device 1 comprises two fixing members 5.

[0042] [Structure of the projector]

[0043] Figure 3 It is a diagram showing the internal structure of the projector 2.

[0044] The projector 2 projects an image corresponding to the image information onto the projection surface SC. Figure 2 and Figure 3 In addition to having an outer casing 3 as shown, Figure 3 As shown in the figure, the projector 2 has an image projection unit 4 housed in an outer casing 3. Although not shown in the figure, the projector 2 has 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.

[0045] In the following description, three directions perpendicular to each other are defined as +X direction, +Y direction, and +Z direction. Although not shown in the figure, the direction opposite to the +X direction is defined as -X direction, the direction opposite to the +Y direction is defined as -Y direction, and the direction opposite to the +Z direction is defined as -Z direction. In addition, although not shown in the figure, the axis along the +X direction is defined as X axis, the axis along the +Y direction is defined as Y axis, and the axis along the +Z direction is defined as Z axis. The X axis is equivalent to the first axis, the Z axis is equivalent to the second axis, and the Y axis is equivalent to the third axis.

[0046] [Structure of image projection unit]

[0047] First, the image projection unit 4 will be described.

[0048] The image projection unit 4 generates an image corresponding to the image signal input from the control device, and projects the generated image. Figure 3 As shown, the image projection unit 4 has a light source device 41 , an image forming device 42 and a projection optical device 43 .

[0049] The image projection unit 4 is formed in a substantially L-shape extending from a position in the +X direction and the −Z direction in the outer casing 3 in the +Z direction and then bending in the −X direction at the center of the outer casing 3 on the Z axis.

[0050] [Structure of light source device]

[0051] 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.

[0052] [Structure of Image Forming Apparatus]

[0053] The image forming device 42 forms image light based on 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.

[0054] 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.

[0055] 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.

[0056] [Structure of projection optical device]

[0057] 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 housing 431 extending in the +X direction and then in the +Z direction, an optical path changing element (not shown), and a magnifying reflecting member.

[0058] The lens housing 431 accommodates a plurality of lenses therein and has an incident portion 432 , a curved portion 433 , and an emitting portion 434 .

[0059] The incident portion 432 is a portion through which image light incident from the color synthesis element 422 in the +Z direction passes.

[0060] 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 +Z direction to the -X direction.

[0061] 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.

[0062] [Structure of the outer casing]

[0063] Figure 4 It is a perspective view showing the projector 2 as viewed from the back surface portion 32 side.

[0064] The outer casing 3 is a casing constituting the exterior of the projector 2. The outer casing 3 includes an upper casing 3U constituting a portion in the +Y direction and a lower casing 3L constituting a portion in the -Y direction, and the upper casing 3U and the lower casing 3L are combined to form a substantially rectangular parallelepiped shape. The outer casing 3 includes a front portion 31, a back portion 32, a left side face portion 33, a right side face portion 34, a top face portion 35, and a bottom face portion 36.

[0065] The front part 31, the back part 32, the left side part 33 and the right side part 34 are respectively formed by a part of the upper case 3U and a part of the lower case 3L. The top part 35 is formed by the upper case 3U, and the bottom part 36 is formed by the lower case 3L. In addition, the lower case 3L has a protrusion 3B1 protruding in the -Y direction.

[0066] The front portion 31 and the back portion 32 constitute surfaces on opposite sides of each other on the X axis. The front portion 31 is an outer surface portion of the projector 2 observed from the -X direction, and is an outer surface portion facing the -X direction. The back portion 32 is an outer surface portion of the projector 2 observed from the +X direction, and is an outer surface portion facing the +X direction.

[0067] The left side face 33 and the right side face 34 constitute surfaces on opposite sides of each other on the Z axis. The left side face 33 is an outer surface of the projector 2 viewed from the -Z direction, and is an outer surface facing the -Z direction. The right side face 34 is an outer surface of the projector 2 viewed from the +Z direction, and is an outer surface facing the +Z direction.

[0068] In the protruding portion 3B1, the surface facing the -X direction constitutes a part of the front portion 31, and the surface facing the +X direction constitutes a part of the back portion 32. In the protruding portion 3B1, the surface facing the -Z direction constitutes a part of the left side portion 33, the surface facing the +Z direction constitutes a part of the right side portion 34, and the surface facing the -Y direction constitutes the bottom portion 36.

[0069] The top surface portion 35 and the bottom surface portion 36 are outer surface surfaces located on opposite sides to each other on the Y axis.

[0070] The top surface portion 35 is an outer surface portion of the projector 2 viewed from the +Y direction, and is an outer surface portion facing the +Y direction. The top surface portion 35 has a recessed portion 351 recessed toward the bottom surface portion 36 and a projection port 352 provided at the bottom of the recessed portion 351. The projection port 352 is an opening portion through which image light projected from the projection optical device 43 described later passes.

[0071] Figure 5 It is a bottom view showing the projector 2 .

[0072] The bottom surface 36 is the outer surface of the projector 2 viewed from the -Y direction and is the outer surface facing the -Y direction. The bottom surface 36 faces the installation surface SF on which the projector 2 is installed. Figure 4 and Figure 5 As shown, the bottom surface portion 36 has a fixed leg portion 361 , a movable leg portion 362 , an introduction port 363 , and a screw hole 364 .

[0073] The fixing leg portions 361 are provided at both end portions of the bottom surface portion 36 on the front surface portion 31 side, and are in contact with the installation surface SF. Two fixing leg portions 361 are provided on the bottom surface portion 36 .

[0074] The movable leg portion 362 is provided at the center of the end portion on the back portion 32 side of the bottom portion 36. The movable leg portion 362 is provided so as to be able to protrude and retract in a direction perpendicular to the bottom portion 36. By making the movable leg portion 362 protrude from the bottom portion 36, the bottom portion 36 is inclined relative to the installation surface SF. Thus, the projection position of the image light projected from the top portion 35 on the projection surface SC is adjusted.

[0075] The introduction port 363 introduces the external air of the outer casing 3 into the interior of the outer casing 3 .

[0076] A plurality of screw holes 364 are provided in the bottom surface portion 36. Accessory screws (not shown) are inserted into the plurality of screw holes 364. The accessory (not shown) fixes the projector 2 to the ceiling or the side wall in a suspended state.

[0077] [Structure of the concave portion]

[0078] like Figure 4 and Figure 5As shown, the outer casing 3 has at least one recess 37 provided on the outer surface. In the present embodiment, the recess 37 is provided on the protruding portion 3B1. Specifically, the recess 37 is provided on the surface facing the -Z direction and the surface facing the +Z direction in the protruding portion 3B1. That is, the outer casing 3 has a recess 37 provided on the left side surface 33 and a recess 37 provided on the right side surface 34. A fixing member 5 is inserted into each recess 37, thereby fixing the projector 2 to the installation surface SF.

[0079] In addition, the recessed portion 37 may be provided in a portion of the outer surface portion of the exterior case 3 different from the protruding portion 3B1 .

[0080] Figure 6 It is a side view showing the recessed portion 37 of the left side surface portion 33 as viewed from the -Z direction.

[0081] The recess 37 is formed so as to be recessed from the left side surface 33 toward the inner side of the outer casing 3. Figure 6 As shown, when viewed from a position that is on the upper side in the +Y direction and directly facing the recess 37, the recess 37 has a first contact surface 371 provided on the left side, a second contact surface 372 provided on the right side, and a third contact surface 373 provided on the front side.

[0082] That is, in the recess 37 provided in the left side surface 33, the first contact surface 371 is a plane arranged in the +X direction and facing the -X direction. The first contact surface 371 is inclined relative to the YZ plane so as to be located in the +X direction as it faces the setting surface SF. When the fixing member 5 is inserted into the recess 37, the first contact surface 371 contacts the first opposing surface 521 of the fixing member 5 described later.

[0083] The second contact surface 372 is a plane arranged in the -X direction and facing the +X direction. That is, the second contact surface 372 is opposite to the first contact surface 371 on the X axis. The second contact surface 372 is inclined relative to the YZ plane so as to be located in the -X direction as it faces the setting surface SF. When the fixing member 5 is inserted into the recessed portion 37, the second contact surface 372 contacts the second opposing surface 522 of the fixing member 5 described later.

[0084] In this way, by inclining the first contact surface 371 and the second contact surface 372 with respect to the YZ plane, the interval between the first contact surface 371 and the second contact surface 372 on the X axis increases toward the setting surface SF. In other words, the first contact surface 371 and the second contact surface 372 are formed into a tapered shape in which the interval between them increases toward the setting surface SF.

[0085] The third contact surface 373 connects the first contact surface 371 and the second contact surface 372. That is, the third contact surface 373 constitutes the bottom of the recess 37 that is recessed in the +Z direction and is a flat surface facing the -Z direction. When the fixing member 5 is inserted into the recess 37, the third contact surface 373 contacts the third opposing surface 523 of the fixing member 5 described later. Figure 6 Although not shown in the figure, the third contact surface 373 of the left side surface portion 33 is inclined with respect to the XY plane so as to be located in the +Z direction as it approaches the installation surface SF.

[0086] In this way, the recessed portion 37 opens toward the −Y direction and also opens toward the outside of the outer case 3 when viewed from the −Y direction.

[0087] The recess 37 provided in the right side surface 34 has the same structure as the recess 37 provided in the left side surface 33. That is, the recess 37 of the right side surface 34 has a first contact surface 371, a second contact surface 372 and a third contact surface 373, which are open in the +Z direction and the -Y direction, respectively.

[0088] In the recessed portion 37 of the right side surface portion 34 , the first contact surface 371 is provided on the left side when viewed with the +Y direction facing upward, that is, in the −X direction, and is a flat surface facing the +X direction.

[0089] In the recessed portion 37 of the right side surface portion 34 , the second contact surface 372 is provided on the right side when viewed with the +Y direction facing upward, that is, in the +X direction, and is a flat surface facing the −X direction.

[0090] In the recessed portion 37 of the right side surface portion 34 , the third contact surface 373 constitutes the bottom of the recessed portion 37 recessed in the −Z direction, and is a flat surface facing the +Z direction.

[0091] When the fixing tool 5 is inserted into the recess 37 of the right side surface 34 , first, second, and third facing surfaces 521 , 522 , and 523 of the fixing tool 5 described below also contact the first, second, and third contact surfaces 371 , 372 , and 373 .

[0092] [Structure of the fixing member]

[0093] The fixing member 5 is inserted into the recessed portion 37 in a state fixed to the installation surface SF, thereby restricting the movement of the projector 2 along the installation surface SF. In this embodiment, since the recessed portion 37 is provided on the left side face portion 33 and the right side face portion 34, Figure 2 As shown, the fixing member 5 is provided on the left side surface 33 and the right side surface 34 which are opposite to each other on the Z axis.

[0094] Figure 7 This is a perspective view of the fixing tool 5 inserted into the recessed portion 37 of the left side surface portion 33 as viewed from the +Y direction and the −Z direction. Figure 8 is a top view of the fixing member 5 as viewed from the +Y direction, Fig. 9 This is a bottom view of the fixing member 5 as viewed from the -Y direction. Figure 7-Figure 8 In FIG. 1 , the +X direction, the +Y direction, and the +Z direction are shown corresponding to the fixing member 5 inserted into the recessed portion 37 of the left side surface portion 33 .

[0095] like Figure 7 to Figure 9 As shown, the fixing member 5 has a fixing portion 51, as shown in FIG. Figure 7 and Figure 8 As shown, a projection 52 is also provided.

[0096] The fixing portion 51 is formed in a substantially rectangular shape when viewed from the +Y direction and is fixed to the installation surface SF. Fig. 9 As shown, the surface of the fixing portion 51 in the -Y direction can be installed with an adhesive tape AT, and the fixing member 5 can be fixed to the installation surface SF by the adhesive tape AT. Fig. 9 In the example, two adhesive tapes AT arranged along the +Z direction and in the +X direction are provided in the +Z direction region of the -Y direction surface of the fixing portion 51. However, in addition to being able to appropriately change the arrangement and number of the adhesive tapes AT, an adhesive may be used instead of the adhesive tapes AT.

[0097] like Figure 7 to Figure 9 As shown, the fixing portion 51 has two fixing holes 511 arranged corresponding to two corners in the -Z direction.

[0098] Screws (not shown) for fixing the fixing tool 5 to the installation surface SF are inserted from the +Y direction into the two fixing holes 511. That is, the fixing tool 5 can be fixed to the installation surface SF by at least one of the adhesive tape AT, the adhesive, and the screws.

[0099] Fig.10 This is a side view of the fixing tool 5 with the protrusion 52 inserted into the recess 37 of the left side surface portion 33 as viewed from the −Z direction. Fig.11 1 is a diagram showing a cross section of the projector device 1 along the YZ plane in a state where the protrusion 52 is inserted into the recess 37 of the left side surface portion 33 .

[0100] like Figure 7 and Figure 8 As shown, the protrusion 52 is a portion protruding from the fixing portion 51 in the +Y direction and is inserted into the recess 37. The protrusion 52 has a first facing surface 521, a second facing surface 522, a third facing surface 523 and a side surface 524, and is formed in a quadrangular pyramid shape.

[0101] like Figure 7 and Figure 8 As shown, the first facing surface 521 is the surface of the protrusion 52 that faces the +X direction. When the protrusion 52 is inserted into the recess 37, as shown in FIG. Fig.10 As shown, the first opposing surface 521 faces and contacts the first contact surface 371 .

[0102] like Figure 7 and Figure 8 As shown in FIG. 1 , the second facing surface 522 is a surface of the protrusion 52 that faces the −X direction. When the protrusion 52 is inserted into the recess 37, as shown in FIG. Fig.10 As shown, the second opposing surface 522 faces and contacts the second contact surface 372 .

[0103] like Figure 7 and Figure 8 As shown, the third facing surface 523 is the surface of the protrusion 52 facing the +Z direction. When the protrusion 52 is inserted into the recess 37, as shown in FIG. Fig.11 As shown, the third opposing surface 523 faces and contacts the third contact surface 373 .

[0104] like Figure 7 and Figure 8 As shown, the side surface 524 is a surface of the protrusion 52 facing the −Z direction.

[0105] Such a protrusion 52 is formed in a tapered shape in which the area of ​​the cross section of the protrusion 52 along the XZ plane increases toward the installation surface SF.

[0106] In detail, Fig.10 As shown, the first opposing surface 521 is inclined relative to the YZ plane in a manner of being located in the +X direction toward the setting surface SF, and the second opposing surface 522 is inclined relative to the YZ plane in a manner of being located in the -X direction toward the setting surface SF. Therefore, the dimension between the first opposing surface 521 and the second opposing surface 522 increases toward the setting surface SF.

[0107] In addition, if Fig.11 As shown, the third opposing surface 523 is inclined relative to the XY plane in a manner that it is located in the +Z direction as it approaches the setting surface SF. On the other hand, the side surface 524 is substantially parallel to the XY plane. Therefore, the dimension between the third opposing surface 523 and the side surface 524 increases as it approaches the setting surface SF.

[0108] By forming the protrusion 52 in this manner, when the protrusion 52 is inserted into the recess 37 , the facing surfaces 521 , 522 , 523 come into surface contact with the contact surfaces 371 , 372 , 373 of the recess 37 .

[0109] As described above, the contact surfaces 371, 372, 373 and the facing surfaces 521, 522, 523 are respectively planes. However, the present invention is not limited thereto, and the contact surfaces 371, 372, 373 and the facing surfaces 521, 522, 523 may not be planes as long as the protrusion 52 can contact the contact surfaces 371, 372, 373 respectively.

[0110] [Fix the projector with the fixing parts]

[0111] When the projector 2 is fixed to the installation surface SF by the fixing member 5, the projector 2 is first 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 part of each image displayed on the projection surface SC by the image light projected from each projector 2 onto the projection surface SC overlaps with each other, or where each image is adjacent to each other.

[0112] Next, after the fixing tool 5 is arranged so that the protruding portion 52 is inserted into the recessed portion 37 of the projector 2 , the fixing tool 5 is fixed to the installation surface SF using the adhesive tape AT, an adhesive, or a screw.

[0113] Thereby, the fixing member 5 is fixed to the installation surface SF, and further, the projector 2 is fixed to the installation surface SF.

[0114] [Movement restrictions of the projector by the fixing parts and recesses]

[0115] Fig.12 This is a diagram for explaining the restriction of the movement of the projector 2 by the fixing member 5 .

[0116] like Fig.12 As shown, when the external force F1 in the +X direction acts on the projector 2, the movement of the projector 2 in the +X direction is restricted by the second facing surface 522 of the fixing member 5 in contact with the second contact surface 372 of the recessed portion 37 of the left side surface 33, and is restricted by the first facing surface 521 of the fixing member 5 in contact with the first contact surface 371 of the recessed portion 37 of the right side surface 34. Thus, the movement of the projector 2 in the +X direction is restricted.

[0117] When the external force F2 in the -X direction acts on the projector 2, the movement of the projector 2 in the -X direction is restricted by the first facing surface 521 of the fixing member 5 in contact with the first contact surface 371 of the recessed portion 37 of the left side surface 33, and is restricted by the second facing surface 522 of the fixing member 5 in contact with the second contact surface 372 of the recessed portion 37 of the right side surface 34. Thus, the movement of the projector 2 in the -X direction is restricted.

[0118] When the external force F3 in the +Z direction acts on the projector 2, the movement of the projector 2 in the +Z direction is restricted by the third facing surface 523 of the fixing member 5 in contact with the third contact surface 373 of the recessed portion 37 of the right side surface 34. Thus, the movement of the projector 2 in the +Z direction is restricted.

[0119] When the external force F4 in the -Z direction acts on the projector 2, the movement of the projector 2 in the -Z direction is restricted by the third facing surface 523 of the fixing member 5 contacting the third contact surface 373 of the recessed portion 37 of the left side surface 33. Thus, the movement of the projector 2 in the -Z direction is restricted.

[0120] The same applies when an external force in a direction perpendicular to the Y axis and inclined in the ±X direction and the ±Z direction acts on the projector 2 .

[0121] 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, the projector 2 can be prevented from moving along the installation surface SF by the fixing device 5 .

[0122] Furthermore, since the recessed portion 37 opens in the -Y direction, the projector 2 can move in the Y-axis direction away from the installation surface SF relative to the fixture 5 fixed to the installation surface SF. Therefore, by moving the projector 2 disposed on the installation surface SF in the +Y direction, the protruding portion 52 inserted into the recessed portion 37 can be separated from the recessed portion 37, and the projector 2 can be moved from the installation surface SF in the +Y direction.

[0123] [Effects of the First Embodiment]

[0124] The projection system PS of the present embodiment described above has the following effects.

[0125] The projection system PS includes a plurality of projector devices 1 , and images projected from the plurality of projector devices 1 form a single continuous image.

[0126] Projector device 1 includes a projector 2 and a fixing element 5 .

[0127] The projector 2 includes a front portion 31, a back portion 32, a left side portion 33, a right side portion 34, a top portion 35, and a bottom portion 36. The front portion 31 and the back portion 32 are arranged on opposite sides to each other on the X axis, the left side portion 33 and the right side portion 34 are arranged on opposite sides to each other on the Z axis, and the top portion 35 and the bottom portion 36 are arranged on opposite sides to each other on the Y axis. The front portion 31, the back portion 32, the left side portion 33, and the right side portion 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.

[0128] The fixing member 5 is fixed to the installation surface SF intersecting the Y axis. The fixing member 5 has a fixing portion 51 fixed to the installation surface SF and a protruding portion 52 protruding along the Y axis.

[0129] The recessed portion 37 is provided in at least one of the front portion 31, the rear portion 32, the left side surface 33, and the right side surface 34. In the projector 2, the recessed portion 37 is provided in the left side surface 33 and the right side surface 34, respectively.

[0130] Each recessed portion 37 has a first contact surface 371, a second contact surface 372, and a third contact surface 373. Specifically, in the recessed portion 37 provided on the left side face portion 33, the first contact surface 371 is opposed in the -X direction, the second contact surface 372 is opposed in the +X direction, and the third contact surface 373 is opposed in the +Z direction. In the recessed portion provided on the right side face portion 34, the first contact surface 371 is opposed in the +X direction, the second contact surface 372 is opposed in the -X direction, and the third contact surface 373 is opposed in the -Z direction. That is, the recessed portion 37 has three contact surfaces opposed in at least three directions of the first direction along the X axis, the direction opposite to the first direction, the second direction along the Z axis, and the direction opposite to the second direction.

[0131] The protrusion 52 is in contact with the first contact surface 371 , the second contact surface 372 , and the third contact surface 373 .

[0132] According to such a configuration, the protrusion 52 of one fixture 5 fixed to the installation surface SF contacts the outer casing 3 in at least three directions among the four directions of +X direction, -X direction, +Z direction and -Z direction. Thus, the movement of the projector 2 can be restricted when an external force in the direction in which each contact surface 371 to 373 contacts the protrusion 52 acts. Furthermore, since each contact surface 371 to 373 contacts the protrusion 52, the movement of the projector 2 can be restricted in the same manner even when an external force in a direction oblique to the direction in which each contact surface 371 to 373 contacts the protrusion 52 acts. Therefore, the movement of the projector 2 in at least three directions perpendicular to the Y axis can be restricted by one fixture 5, and thus the directions in which the movement of the projector 2 can be restricted can be increased. Furthermore, the projector 2 can be prevented from deviating from a preset fixed position, and the projection position of the image of the projector 2 can be prevented from changing. Furthermore, the position alignment of the projector 2 of each projector device 1 with respect to the installation surface SF can be easily performed, and further, the position alignment of the image projected from each projector 2 can be easily performed.

[0133] In the projector device 1, two outer surface portions on opposite sides of one axis of the X-axis and the Z-axis respectively have a first contact surface 371, a second contact surface 372, and a third contact surface 373. Specifically, the projector 2 has a recessed portion 37 provided on the left side surface 33 and a recessed portion 37 provided on the right side surface 34, and each recessed portion 37 has a first contact surface 371, a second contact surface 372, and a third contact surface 373.

[0134] The fixing member 5 is disposed corresponding to the left side surface portion 33 and the right side surface portion 34 , respectively.

[0135] According to such a configuration, even when external forces in the four directions described above act on the projector 2 , movement of the projector 2 on the installation surface SF can be restricted by at least two fixing members 5 .

[0136] Furthermore, since the movement of the projector 2 is restricted by at least two fixing members 5 , even when a rotational force centered on the rotation axis along the Y-axis acts on the projector 2 , the rotation of the projector 2 can be restricted.

[0137] In the projector device 1, the first contact surface 371, the second contact surface 372, and the third contact surface 373 are formed by the recessed portion 37 provided in at least one outer surface portion. That is, the recessed portion 37 provided in at least one outer surface portion has the contact surfaces 371 to 373, respectively.

[0138] According to such a configuration, it is possible to suppress the outer size of the projector 2 from increasing. Therefore, it is possible to suppress the installation area of ​​the projector device 1 from increasing in size.

[0139] In the projector device 1, the first contact surface 371 and the second contact surface 372 of the first contact surface 371, the second contact surface 372 and the third contact surface 373 face each other. The interval between the two contact surfaces 371 and 372 along the X axis increases toward the installation surface SF.

[0140] According to such a configuration, the exterior case 3 can be easily engaged with the fixing member 5 fixed to the installation surface SF. Therefore, the projector 2 can be easily fixed by the fixing member 5.

[0141] In the projector device 1 , the projector 2 can move from the fixing member 5 along the Y axis in the +Y direction away from the installation surface SF.

[0142] According to such a structure, the projector 2 can be attached to and detached from the installation surface SF without shifting the fixture 5 fixed to the installation surface SF. Therefore, by moving the projector 2 in the direction away from the installation surface SF along the Y axis, the fixing of the projector 2 by the fixture 5 can be released. In addition, by moving the projector 2 in the -Y direction approaching the installation surface SF along the Y axis, the projector 2 can be fixed to the installation surface SF by the fixture 5. Therefore, the convenience of the projector 2 can be improved.

[0143] [Variation of the first embodiment]

[0144] In the above-mentioned projector device 1, the recessed portion 37 having the first contact surface 371, the second contact surface 372, and the third contact surface 373 is provided on the left side face 33 and the right side face 34 of the front portion 31, the back portion 32, the left side face 33, and the right side face 34. However, the present invention is not limited thereto, and the recessed portion 37 may be provided on one of the outer surface face portions of the front portion 31 and the back portion 32 and one of the outer surface face portions of the left side face 33 and the right side face 34, respectively. For example Fig.13 As shown, the recessed portion 37 may be provided on the front surface portion 31 and the left side surface portion 33. In this case, the fixing member 5 is disposed corresponding to the two outer surface portions provided with the recessed portion 37, respectively.

[0145] According to such a structure, similar to the above-mentioned projector device 1, even when external forces in the above-mentioned four directions act on the projector 2, the movement of the projector 2 on the installation surface SF can be restricted. In addition, even when a rotational force centered on the rotation axis along the Y axis acts on the projector 2, the rotation of the projector 2 can be restricted by the two fixing members 5.

[0146] [Second embodiment]

[0147] Next, a second embodiment of the present invention will be described.

[0148] The projection system of this embodiment has the same structure as the projection system PS of the first embodiment, but the structures of the fixing member and the outer casing are different. Specifically, in the projection system PS of the first embodiment, the protrusion 52 is provided on the fixing member 5 fixed to the setting surface SF, and the recess 37 for inserting the protrusion 52 is provided on the outer casing 3 of the projector 2. In contrast, in the projection system of this embodiment, the recess is provided on the fixing member, and the protrusion inserted into the recess is provided on the outer casing. 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 thereof is omitted.

[0149] [Schematic structure of the projection system]

[0150] Fig.14 It is a plan view of the projector device 1A according to the present embodiment as viewed from the -Y direction.

[0151] The projection system of the present embodiment includes a plurality of projector devices 1A arranged on an installation surface SF, and has the same function as that of the projection system PS of the first embodiment.

[0152] like Fig.14 As shown, each of the plurality of projector devices 1A includes a projector 2A and a fixture 5A.

[0153] [Structure of the projector]

[0154] The projector 2A has the same structure and function as the projector 2 of the first embodiment, except that it includes an exterior casing 3A instead of the exterior casing 3 .

[0155] The outer casing 3A has the same structure and function as the outer casing 3 except that the convex portion 38 is provided instead of the concave portion 37. That is, the outer casing 3A has the convex portion 38 in addition to the front portion 31, the back portion 32, the left side portion 33, the right side portion 34, the top portion 35 and the bottom portion 36.

[0156] The convex portion 38 is provided on at least one outer surface of the front portion 31, the rear portion 32, the left side surface 33, and the right side surface 34. In the present embodiment, the projector 2A has the convex portion 38 provided on the left side surface 33 and the right side surface 34, respectively.

[0157] Fig.15 The figure shows the cross section along the XZ plane of the protrusion 38 and the fixing tool 5A into which the protrusion 38 is inserted.

[0158] The convex portion 38 provided on the left side surface 33 protrudes in the -Z direction in a substantially rectangular shape when viewed from the +Y direction. Fig.15 As shown, when viewed from a position that is on the upper side in the +Y direction and directly facing the protrusion 38, the protrusion 38 has a first contact surface 381 provided on the left side, a second contact surface 382 provided on the right side, and a third contact surface 383 provided on the front side.

[0159] In the convex portion 38 of the left side surface 33, the first contact surface 381 is a plane arranged in the +X direction and facing the +X direction in the convex portion 38. The first contact surface 381 is inclined relative to the YZ plane so as to be located in the +X direction toward the installation surface SF, similarly to the first contact surface 371 of the first embodiment.

[0160] In the convex portion 38 of the left side surface 33, the second contact surface 382 is a plane arranged in the -X direction and facing the -X direction in the convex portion 38. The second contact surface 382 is inclined relative to the YZ plane so as to be located in the -X direction toward the installation surface SF, similarly to the second contact surface 372 of the first embodiment.

[0161] In the convex portion 38 of the left side surface 33, the third contact surface 383 is a plane arranged in the -Z direction and facing the -Z direction in the convex portion 38. The third contact surface 383 is inclined relative to the XY plane so as to be located in the -Z direction toward the installation surface SF, similarly to the third contact surface 373 of the first embodiment.

[0162] Furthermore, the contact surfaces 381 and 382 do not need to be inclined with respect to the YZ plane, and the third contact surface 373 does not need to be inclined with respect to the XY plane.

[0163] The convex portion 38 of the right side surface portion 34 has the same structure as the convex portion 38 of the left side surface portion 33 .

[0164] [Structure of the fixing member]

[0165] The fixing member 5A is fixed to the installation surface SF, and the protrusion 38 is inserted to restrict the movement of the projector 2A along the installation surface SF. In this embodiment, the protrusion 38 is respectively provided on the left side surface 33 and the right side surface 34. Fig.14 As shown, the fixing members 5A are provided corresponding to the left side surface portion 33 and the right side surface portion 34 which are on opposite sides to each other on the Z axis.

[0166] The fixing tool 5A has the same structure and function as the fixing tool 5 of the first embodiment, except that the fixing tool 5A has a protruding portion 53 instead of the protruding portion 52. That is, the fixing tool 5A has a fixing portion 51 fixed to the installation surface SF and the protruding portion 53.

[0167] The protrusion 53 protrudes in the +Y direction from the fixing portion 51. The protrusion 53 is provided with a recess 54 that opens in the +Y direction and faces the convex portion 38. That is, the fixing member 5A has the recess 54 into which the convex portion 38 is inserted.

[0168] In the fixing member 5A disposed corresponding to the left side surface 33 , the recessed portion 54 has a first facing surface 541 facing the inner surface in the −X direction, a second facing surface 542 facing the inner surface in the +X direction, and a third facing surface 543 facing the inner surface in the +Z direction.

[0169] When the convex portion 38 of the left side surface 33 is inserted into the concave portion 54, the first opposing surface 541 is a plane that is in contact with the first contact surface 381, the second opposing surface 542 is a plane that is in contact with the second contact surface 382, ​​and the third opposing surface 543 is a plane that is in contact with the third contact surface 383.

[0170] Each of the facing surfaces 541 to 543 is inclined corresponding to the corresponding contact surface among the contact surfaces 381 to 383 of the convex portion 38 , but may not be inclined when the corresponding contact surface is not inclined.

[0171] In addition, the outer surface of the outer casing 3A provided with the convex portion 38 is not limited to the left side surface 33 and the right side surface 34. For example, the convex portion 38 may be provided on the front side 31 and the back side 32. For another example, the convex portion 38 may be provided on one of the outer surface of the front side 31 and the back side 32 and one of the left side surface 33 and the right side surface 34.

[0172] [Effects of the Second Embodiment]

[0173] The projection system of the present embodiment described above achieves the following effects in addition to the same effects as the projection system PS of the first embodiment.

[0174] In the projector device 1A, the first contact surface 381, the second contact surface 382, ​​and the third contact surface 383 are formed by the convex portion 38 provided on at least one outer surface of the front portion 31, the back portion 32, the left side surface 33, and the right side surface 34. In addition, as described above, the front portion 31, the back portion 32, the left side surface 33, and the right side surface 34 correspond to the first face portion, the second face portion, the third face portion, and the fourth face portion.

[0175] According to such a configuration, the volume of the projector 2A does not decrease. Therefore, the degree of freedom in layout of the internal structure of the projector 2A does not decrease, and movement of the projector 2A on the installation surface SF can be suppressed.

[0176] [Third embodiment]

[0177] Next, a third embodiment of the present invention will be described.

[0178] The projection system of this embodiment has the same structure as the projection system PS of the first embodiment. Here, in the projection system PS of the first embodiment, the movement of the projector 2 on the installation surface SF is restricted by inserting the fixing member 5 into the recessed portion 37 provided in the outer casing 3. In contrast, in the projection system of this embodiment, the movement of the projector on the installation surface SF is restricted by inserting the fixing member fixed to the installation surface SF into the hole portion provided in the outer casing. In addition, in the following description, the same reference numerals are given to the parts that are the same or substantially the same as the parts that have been described, and the description thereof is omitted.

[0179] [Schematic structure of the projection system]

[0180] Fig.16 It is a bottom view of the projector device 1B included in the projection system according to the present embodiment, as viewed from the -Y direction.

[0181] The projection system of the present embodiment includes a plurality of projector devices 1B arranged on a setting surface SF, and has the same function as that of the projection system PS of the first embodiment.

[0182] like Fig.16 As shown, each of the plurality of projector devices 1B includes a projector 2B and a fixture 5B.

[0183] [Structure of the projector]

[0184] The projector 2B has the same structure and function as the projector 2 of the first embodiment, except that it has an exterior casing 3B instead of the exterior casing 3 .

[0185] The outer casing 3B has the same structure and function as the outer casing 3 except that it has a protruding portion 391 and a hole portion 392 instead of the recessed portion 37. That is, the outer casing 3B has the protruding portion 391 and the hole portion 392 in addition to the front portion 31, the back portion 32, the left side surface portion 33, the right side surface portion 34, the top surface portion 35 and the bottom surface portion 36.

[0186] [Structure of the protruding portion and the hole portion]

[0187] The extension portion 391 protrudes from at least one outer surface of the front portion 31, the back portion 32, the left side surface 33, and the right side surface 34. In the present embodiment, the extension portion 391 protrudes from the back portion 32 in the +X direction.

[0188] The hole 392 is provided in the extension portion 391 in the bottom portion 36 and opens in the -Y direction. The inner surface of the hole 392 includes a first contact surface 393, a second contact surface 394, a third contact surface 395, and a fourth contact surface 396, and the hole 392 is formed in a substantially rectangular shape when viewed from the -Y direction.

[0189] Fig.17 1 and 2 are diagrams showing a cross section of the hole portion 392 and the fixing tool 5B along the XZ plane.

[0190] like Fig.17 As shown in FIG. 1 , the first contact surface 393 is a plane arranged in the −X direction and facing the +X direction. The first contact surface 393 is inclined with respect to the YZ plane so as to be located in the −X direction as it goes toward the installation surface SF.

[0191] The second contact surface 394 is a plane arranged in the +X direction and facing the -X direction. The second contact surface 394 is inclined with respect to the YZ plane so as to be located in the +X direction as it goes toward the installation surface SF.

[0192] In this way, the first contact surface 393 and the second contact surface 394 are opposite to each other on the X-axis. Since the first contact surface 393 and the second contact surface 394 are respectively inclined relative to the YZ plane, the interval between the first contact surface 393 and the second contact surface 394 on the X-axis increases as it goes toward the setting surface SF. In other words, the first contact surface 393 and the second contact surface 394 are formed into a tapered shape in which the interval between them increases toward the setting surface SF.

[0193] The third contact surface 395 is a plane arranged in the -Z direction and facing the +Z direction. The third contact surface 395 is inclined with respect to the XY plane so as to be located in the -Z direction as it goes toward the installation surface SF.

[0194] The fourth contact surface 396 is a plane arranged in the +Z direction and facing the -Z direction. The fourth contact surface 396 is inclined with respect to the XY plane so as to be located in the +Z direction as it goes toward the installation surface SF.

[0195] Thus, the third contact surface 395 and the fourth contact surface 396 are opposed to each other on the Z axis. Since the third contact surface 395 and the fourth contact surface 396 are respectively inclined relative to the XY plane, the interval between the third contact surface 395 and the fourth contact surface 396 on the Z axis increases toward the setting surface SF. In other words, the third contact surface 395 and the fourth contact surface 396 are formed into a tapered shape in which the interval between them increases toward the setting surface SF.

[0196] Furthermore, at least one of the first contact surface 393 , the second contact surface 394 , the third contact surface 395 , and the fourth contact surface 396 may not be a flat surface.

[0197] Furthermore, the shape of the hole 392 is not limited to a rectangle, but may be a triangle, or a polygon larger than a pentagon. In addition, the hole 392 may not be formed into a tapered shape whose cross section perpendicular to the Y axis becomes larger as it moves toward the installation surface. On the other hand, at least one of the contact surfaces 393 to 396 may not be inclined.

[0198] [Structure of the fixing member]

[0199] The fixing tool 5B has the same structure and function as the fixing tool 5 except that the fixing tool 5B has a protruding part 55 instead of the protruding part 52. That is, the fixing tool 5B has the fixing part 51 and the protruding part 55.

[0200] The protrusion 55 protrudes in the +Y direction from the fixing portion 51. The protrusion 55 is inserted into the hole 392 from the -Y direction to restrict movement of the projector 2B on the installation surface SF.

[0201] The protruding portion 55 has a first opposing surface 551 , a second opposing surface 552 , a third opposing surface 553 , and a fourth opposing surface 554 .

[0202] The first facing surface 551 is a plane facing the -X direction in the protrusion 55, and the second facing surface 552 is a plane facing the +X direction. When the protrusion 55 is inserted into the hole 392, the first facing surface 551 faces and contacts the first contact surface 393, and the second facing surface 552 faces and contacts the second contact surface 394.

[0203] The third facing surface 553 is a plane facing the -Z direction in the protrusion 55, and the fourth facing surface 554 is a plane facing the +Z direction. When the protrusion 55 is inserted into the hole 392, the third facing surface 553 faces and contacts the third contact surface 395, and the fourth facing surface 554 faces and contacts the fourth contact surface 396.

[0204] Thus, the protrusion 55 is formed into a tapered shape corresponding to the cross-sectional shape of the hole 392 perpendicular to the Y axis, with the cross-sectional shape perpendicular to the Y axis becoming larger toward the installation surface SF. Thus, each of the facing surfaces 551 to 554 makes surface contact with the corresponding contact surface among the contact surfaces 393 to 396.

[0205] [Restrictions on the movement of the projector by the fixings and holes]

[0206] like Fig.16 As shown, when the external force F1 in the +X direction acts on the projector 2B, the movement of the projector 2B in the +X direction is restricted by the first opposing surface 551 in contact with the first contact surface 393 .

[0207] When the external force F2 in the −X direction acts on the projector 2B, the movement of the projector 2B in the −X direction is restricted by the second opposing surface 552 that is in contact with the second contact surface 394 .

[0208] When the external force F3 in the +Z direction acts on the projector 2B, the movement of the projector 2B in the +Z direction is restricted by the third opposing surface 553 that is in contact with the third contact surface 395 .

[0209] When the external force F4 in the −Z direction acts on the projector 2B, the movement of the projector 2B in the −Z direction is restricted by the fourth opposing surface 554 that is in contact with the fourth contact surface 396 .

[0210] Even when an external force perpendicular to the Y axis and inclined relative to at least one of the +X direction, -X direction, +Z direction and -Z direction acts on projector 2B, the movement of projector 2B is restricted by the protrusion 55 of the fixing member 5B fixed to the setting surface SF.

[0211] Furthermore, the projector 2B can be moved from the installation surface SF by moving in the +Y direction away from the installation surface SF in the Y-axis direction relative to the fixture 5B fixed to the installation surface SF.

[0212] [Effects of the third embodiment]

[0213] The projection system of the present embodiment described above achieves the following effects in addition to the same effects as the projection system PS of the first embodiment.

[0214] In the projector device 1B, the outer casing 3 has a hole portion 392 including a first contact surface 393 facing in the -X direction, a second contact surface 394 facing in the +X direction, a third contact surface 395 facing in the -Z direction, and a fourth contact surface 396 facing in the +Z direction on the inner surface. One of the X axis and the Z axis is the first axis, and the other is the second axis. When the X axis is the first axis, one of the +X direction and the -X direction is the first direction along the first axis, and the other is the direction opposite to the first direction. When the Z axis is the second axis, one of the +Z direction and the -Z direction is the second direction along the second axis, and the other is the direction opposite to the second direction.

[0215] The fixing member 5B includes a fixing portion 51 fixed to the installation surface SF and a protruding portion 55 protruding along the Y axis from the fixing portion 51. The protruding portion 55 is inserted into the hole 392 and contacts the contact surfaces 393 to 396.

[0216] According to such a structure, similarly to the projector device 1 of the first embodiment, the protrusion 55 contacts the outer casing 3 in four directions, namely, the +X direction, the -X direction, the +Z direction, and the -Z direction. Thus, the movement of the projector 2B can be restricted when an external force in a direction in which each of the contact surfaces 393 to 396 contacts the protrusion 55 acts. Furthermore, even when an external force in a direction oblique to the direction in which each of the contact surfaces 393 to 396 contacts the protrusion 55 acts, the movement of the projector 2B can be restricted in the same manner. Therefore, the movement of the projector 2B on the installation surface SF can be restricted.

[0217] In the projector device 1B, the hole portion 392 has a first contact surface 393 , a second contact surface 394 , a third contact surface 395 , and a fourth contact surface 396 .

[0218] At least one of the first contact surface 393, the second contact surface 394, the third contact surface 395, and the fourth contact surface 396 is a flat surface. In the present embodiment, each of the contact surfaces 393 to 396 is a flat surface.

[0219] According to such a configuration, the protrusion 55 is in contact with each of the contact surfaces 393 to 396 of the hole 392, so that even when external forces in four directions in which the contact surfaces 393 to 396 and the protrusion 55 are opposed to each other act on the projector 2B, the movement of the projector 2B on the installation surface SF can be restricted. In addition, since the contact surfaces 393 to 396 as planes are in surface contact with the protrusion 55, even when a rotational force centered on the rotation axis along the Y-axis as the third axis acts on the projector 2B, the rotation of the projector 2B can be restricted.

[0220] [Variation of the third embodiment]

[0221] In the above-described projector device 1B, the hole 392 is provided in the bottom surface 36 along the Y axis in the extension portion 391 protruding from the back surface 32. However, the present invention is not limited thereto, and the position where the hole 392 is provided in the bottom surface 36 can be changed as appropriate.

[0222] In addition, the hole portion 392 is provided in the protruding portion 391 , but the present invention is not limited thereto, and the protruding portion 391 may not be provided.

[0223] In this case, the projector device 1B includes a projector 2B having an outer casing 3 and a fixing member 5B fixed to a setting surface SF intersecting the Y axis.

[0224] The outer casing 3 has a front portion 31, a back portion 32, a left side portion 33, a right side portion 34, a top portion 35, and a bottom portion 36, and also has a hole portion 392 including contact surfaces 393 to 396 on the inner surface. In addition, the front portion 31 and the back portion 32 are arranged on opposite sides to each other on the X axis, the left side portion 33 and the right side portion 34 are arranged on opposite sides to each other on the Z axis, and the top portion 35 and the bottom portion 36 are arranged on opposite sides to each other on the Y axis. The front portion 31, the back portion 32, the left side portion 33, the right side portion 34, the top portion 35, and the bottom portion 36 correspond to the first surface, the second surface, the third surface, the fourth surface, the fifth surface, and the sixth 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.

[0225] The fixing member 5B includes a fixing portion 51 fixed to the installation surface SF and a protruding portion 55 protruding along the Y axis from the fixing portion 51. The protruding portion 55 is inserted into the hole 392 and contacts the contact surfaces 393 to 396.

[0226] Furthermore, the hole portion 392 and the protrusion 55 restrict the projector 2B from rotating about an axis along the Y-axis.

[0227] According to such a structure, the movement of the projector 2B in the direction intersecting the Y axis and the movement of the projector 2B centered on the axis along the Y axis can be restricted by the hole 392 of the outer casing 3 and the protrusion 55 of the fixing member 5B fixed to the installation surface SF. Therefore, the movement of the projector 2B on the installation surface SF can be restricted.

[0228] In the above-mentioned projector device 1B, as long as the hole 392 and the protrusion 55 restrict the rotation of the projector 2B around the axis along the Y axis, the contact surface between the hole 392 and the protrusion 55 may not be a plane. For example, the hole 392 and the protrusion 55 only need to have a surface that resists the rotation of the projector 2B around the axis along the Y axis. As the shape of the hole 392, an elliptical shape, a circular shape having a plane in part, etc. can be exemplified.

[0229] [Fourth embodiment]

[0230] Next, a fourth embodiment of the present invention will be described.

[0231] The projection system of this embodiment has the same structure as the projection system PS of the third embodiment. Here, in the projection system of the third embodiment, the hole 392 is provided in the back surface 32 of the outer casing 3B. In contrast, in the projection system of this embodiment, the outer casing is composed of a casing body and a cover member, and the hole 392 is formed by the casing body and the cover member. In addition, in the following description, the same reference numerals are attached to the parts that are the same or substantially the same as the parts that have been described, and the description thereof is omitted.

[0232] [Schematic structure of the projection system]

[0233] Fig.18 It is a bottom view of the projector device 1C constituting the projection system of the present embodiment, as viewed from the -Y direction.

[0234] The projection system of this embodiment has multiple Fig.18 The projector device 1C shown has the same function as the projection system PS of the first embodiment.

[0235] The projector device 1C includes a projector 2C and a fixture 5B.

[0236] The projector 2C has the same structure and function as the projector 2 of the first embodiment, except that it includes an exterior casing 3C instead of the exterior casing 3 .

[0237] The exterior case 3C includes a case body 3C1 and a cover member CM that can be attached to the case body 3C1.

[0238] The housing body 3C1 has a front portion 31, a back portion 32, a left side portion 33, a right side portion 34, a top portion 35, and a bottom portion 36 similarly to the exterior housing 3 of the first embodiment, but the housing body 3C1 is not provided with the recessed portion 37 of the first embodiment. When the cover member CM is not mounted on the projector 2C, the housing body 3C1 is an exterior housing constituting the exterior of the projector 2C.

[0239] The cover member CM and the fixing member 5B together constitute a projector fixing device PF for fixing the projector 2C to the installation surface SF. The cover member CM is attached to at least one of the outer surface parts of the front part 31, the back part 32, the left side surface 33 and the right side surface 34 of the housing body 3C1. In the present embodiment, the cover member CM is attached to the back part 32 by a fixing member FM such as a bolt.

[0240] The cover member CM has a recessed portion CM1 that opens in the −Y direction and is recessed in a direction opposite to a direction toward an outer surface portion to which the cover member CM is attached.

[0241] By attaching such a cover member CM to the housing body 3C1, a hole portion 392 whose inner surface is formed by the back portion 32 and the inner surface of the recessed portion CM1 is provided in the outer housing 3C. At this time, a first contact surface 393 facing the +X direction in the inner surface of the hole portion 392 is formed by the back portion 32 of the outer housing 3, and other contact surfaces 394 to 396 are formed by the inner surface of the recessed portion CM1.

[0242] By inserting the protrusion 55 of the fixture 5B fixed to the installation surface SF into the hole 392 formed in this way, the movement of the projector 2C on the installation surface SF is restricted similarly to the projector 2B of the third embodiment.

[0243] [Effects of the Fourth Embodiment]

[0244] The projection system of the present embodiment described above achieves the following effects in addition to the same effects as the projection system PS of the third embodiment.

[0245] In the projector device 1C, an exterior casing 3C of a projector 2C includes a casing body 3C1 and a cover member CM.

[0246] The housing body 3C1 has a front portion 31, a back portion 32, a left side face portion 33, a right side face portion 34, a top face portion 35, and a bottom face portion 36. The front portion 31, the back portion 32, the left side face portion 33, the right side face portion 34, the top face portion 35, and the bottom face portion 36 correspond to a first face portion, a second face portion, a third face portion, a fourth face portion, a fifth face portion, and a sixth face portion.

[0247] The cover member CM is attached to at least one of the front portion 31, the back portion 32, the left side portion 33, and the right side portion 34. In the present embodiment, the cover member CM is attached to the back portion 32. The cover member CM forms a hole portion 392 into which the protrusion 55 of the fixing member 5B is inserted.

[0248] According to such a configuration, by providing the cover member CM on the housing body 3C1, the projector 2C can be configured such that movement on the installation surface SF is restricted by the fixing member 5B. Therefore, if the cover member CM can be attached, for example, the projector device 1C can be configured using an existing projector.

[0249] The projector fixing device PF fixes the projector 2C having the outer casing 3C to a setting plane SF intersecting the Y axis. The outer casing 3C has a front portion 31 , a rear portion 32 , a left side surface 33 , a right side surface 34 , a top surface 35 , and a bottom surface 36 .

[0250] The projector fixing device PF includes a fixing tool 5B and a cover member CM.

[0251] The fixing member 5B is fixed to the installation surface SF.

[0252] The cover member CM is attached to at least one outer surface of the front portion 31, the back portion 32, the left side surface 33, and the right side surface 34. The cover member CM defines a hole portion 392 into which the protrusion 55 as a part of the fixing member 5B is inserted.

[0253] The inner surface of the hole portion 392 includes a first contact surface 393 opposed in the -X direction along the X-axis, a second contact surface 394 opposed in the direction opposite to the -X direction, a third contact surface 395 opposed in the -Z direction along the Z-axis, and a fourth contact surface 396 opposed in the direction opposite to the -Z direction.

[0254] The fixing member 5B has a protrusion 55 that protrudes from the fixing portion 51 along the Y axis, is inserted into the hole 392 , and contacts the contact surfaces 393 to 396 .

[0255] According to such a structure, the protrusion 55 of the fixing member 5B fixed to the installation surface SF contacts the contact surfaces 393 to 396 of the hole 392 formed by the housing body 3C1 and the cover member CM in four directions, namely, the +X direction, the -X direction, the +Z direction, and the -Z direction. Thus, in addition to being able to restrict the movement of the projector 2C when an external force in the direction in which each contact surface 393 to 396 contacts the protrusion 55 acts, the movement of the projector 2C can also be restricted even when an external force in a direction oblique to the direction in which each contact surface 393 to 396 contacts the protrusion 55 acts. Therefore, the movement of the projector 2C on the installation surface SF can be restricted. Furthermore, by providing the cover member CM on the housing body 3C1 of the outer housing 3C, the projector 2C can be configured such that the movement on the installation surface SF can be restricted by the fixing member 5B. Therefore, if it is configured so that the cover member CM can be mounted, for example, the above-mentioned projector device 1C can be configured using an existing projector.

[0256] In the projector fixing device PF, at least one of the first contact surface 393, the second contact surface 394, the third contact surface 395, and the fourth contact surface 396 is a flat surface. In the present embodiment, each of the contact surfaces 393 to 396 is a flat surface.

[0257] According to such a configuration, the flat contact surfaces among the contact surfaces 393 to 396 come into surface contact with the protrusion 55 , so that even when a rotational force centered on the rotation axis along the Y-axis acts on the projector 2C, the rotation of the projector 2C can be restricted.

[0258] In the above-mentioned projector device 1C, as long as the hole 392 and the protrusion 55 restrict the rotation of the projector 2C around the axis along the Y axis, the contact surface between the hole 392 and the protrusion 55 may not be a flat surface. For example, the hole 392 and the protrusion 55 may have a surface that resists the rotation of the projector 2C around the axis along the Y axis. As the shape of the hole 392, an elliptical shape, a circular shape having a flat surface in part, etc. can be exemplified.

[0259] In the projector fixing device PF, the hole portion 392 is constituted by the cover member CM and the outer surface portions of the front portion 31 , the back portion 32 , the left surface portion 33 , and the right surface portion 34 to which the cover member CM is attached.

[0260] According to such a configuration, the size of the cover member CM in the mounting direction of the cover member CM to the exterior casing 3C can be reduced compared to a case where the cover member CM is provided with the hole 392. Therefore, it is possible to suppress an increase in the size of the projector 2C.

[0261] In addition, the hole portion 392 may be provided in the cover member CM.

[0262] In this case, the projector fixing device PF has a fixing member 5B and a cover member CM, and fixes the projector 2C having the outer casing 3C to the installation plane SF intersecting the Y axis. In addition, the outer casing 3C has a front portion 31, a back portion 32, a left side face portion 33, a right side face portion 34, a top face portion 35, and a bottom face portion 36. The front portion 31, the back portion 32, the left side face portion 33, the right side face portion 34, the top face portion 35, and the bottom face portion 36 correspond to the first face portion, the second face portion, the third face portion, the fourth face portion, the fifth face portion, and the sixth face portion.

[0263] The cover member CM is attached to at least one outer surface of the front portion 31, the back portion 32, the left side surface 33, and the right side surface 34. The cover member CM defines a hole portion 392 into which a part of the fixing member 5B is inserted. The hole portion 392 includes a contact surface.

[0264] The fixing member 5B is fixed to the installation surface SF. The fixing member 5B has a protrusion 55 that protrudes from the fixing portion 51 along the Y axis, is inserted into the hole 392, and contacts the contact surface.

[0265] The hole 392 and the protrusion 55 restrict the projector 2C from rotating about an axis along the Y axis. In addition, the contact surface between the hole 392 and the protrusion 55 may not be a flat surface.

[0266] According to such a structure, by installing the cover member CM on the outer casing 3C, the movement of the projector 2C in the direction intersecting the Y axis and the movement of the projector 2C centered on the axis along the Y axis can be restricted by the hole and the protruding portion of the fixing member. Therefore, the movement of the projector on the installation surface can be restricted, and the projector 2C whose movement on the installation surface SF is restricted by the fixing member 5B can be easily configured.

[0267] In this case, in the projector device 1C, the exterior casing 3C includes a casing body 3C1 and a cover member CM.

[0268] The housing body 3C1 has a front surface portion 31 , a back surface portion 32 , a left side surface portion 33 , a right side surface portion 34 , a top surface portion 35 , and a bottom surface portion 36 .

[0269] The cover member CM is attached and fixed to at least one outer surface portion of the front portion 31 , the back portion 32 , the left side surface portion 33 , and the right side surface portion 34 . The cover member CM defines the hole portion 392 .

[0270] According to such a configuration, by providing the cover member CM on the housing body 3C1, the projector 2C can be configured such that movement on the installation surface SF is restricted by the fixing member 5B. Therefore, if the cover member CM can be attached, for example, the projector device 1C can be configured using an existing projector.

[0274] In the first embodiment, the first contact surface 371 of the contact surfaces 371 to 373 of the recessed portion 37 is inclined so as to be located in a direction away from the second contact surface 372 as it approaches the setting surface SF, and the second contact surface 372 is inclined so as to be located in a direction away from the first contact surface 371 as it approaches the setting surface SF. Furthermore, the third contact surface 373 is inclined so as to be located inside the outer casing 3 as it approaches the setting surface SF. However, the present invention is not limited thereto, and at least one of the contact surfaces 371 to 373 may not be inclined, and the facing surface of the fixing member 5 that contacts the at least one contact surface may not be inclined.

[0275] In the above embodiments, the projectors 2, 2A, 2B, 2C are fixed to the installation surface SF by contacting the fixing members 5, 5A, 5B. At this time, at least one of the fixed leg 361 and the movable leg 362 provided on the bottom surface 36 may or may not contact the installation surface SF.

[0276] In the above-mentioned embodiments, the projectors 2, 2A, 2B, and 2C include three light modulators 421R, 421G, and 421B, but the present invention is not limited thereto, and the projector 2 may include two or less or four or more light modulators.

[0277] In the above embodiments, the projection optical device 43 has an amplifying reflection component that reflects the image light incident from the -X direction toward the +X direction and the +Y direction. However, the invention is not limited thereto, and the projection optical device 43 may also project the image light toward the -X direction without the amplifying reflection component.

That is, the projection optical device 43 is configured in an L shape. However, the projection optical device 43 is not limited thereto, and may also be configured in a linear shape.

Thus, the movement of the projector can be restricted when an external force in the direction in which each contact surface contacts the fixing portion acts. Furthermore, since each contact surface contacts the protrusion, the movement of the projector can be restricted in the same manner even when an external force in a direction oblique to the direction in which each contact surface contacts the fixing portion acts.

[0300] According to such a structure, similar to the above-mentioned projector device, even when external forces in the above-mentioned four directions act on the projector, the movement of the projector on the installation surface can be restricted.

Therefore, it is possible to suppress the increase in the installation area of ​​the projector device.

[0317] According to such a structure, similar to the projector device of Supplement 1, the protrusion of the fixing member fixed to the setting surface contacts the outer casing in at least three of the four directions of the first direction, the direction opposite to the first direction, the second direction, and the direction opposite to the second direction. Thus, the movement of the projector can be restricted when an external force in the direction in which each contact surface contacts the fixing portion acts. Furthermore, since each contact surface contacts the protrusion, the movement of the projector can be restricted in the same manner even when an external force in a direction oblique to the direction in which each contact surface contacts the fixing portion acts. Therefore, the movement of the projector on the setting surface can be restricted.

[0318] [Note 7]

[0319] The projector device according to Supplementary Note 6 is characterized in that:

[0320] The outer casing has:

[0321] a shell body having the first face portion, the second face portion, the third face portion, the fourth face portion, the fifth face portion, and the sixth face portion; and

[0322] a cover member fixed to an outer surface of the first face portion, the second face portion, the third face portion, and the fourth face portion,

[0323] The cover member configures the hole portion.

[0324] According to such a structure, by providing the cover member on the housing body, a projector can be constructed in which the movement on the installation surface can be restricted by the fixing member.

In addition, by making the contact surface that is a plane among the first contact surface, the second contact surface, the third contact surface and the fourth contact surface contact with the protrusion, even when a rotational force centered on the rotation axis along the third axis acts on the projector, the rotation of the projector can be restricted.

[0334] [Note 9]

Therefore, the movement of the projector on the installation surface can be restricted.

[0359] According to such a structure, the projector can be attached and detached relative to the installation surface without shifting the fixing member fixed to the installation surface. Therefore, by moving the projector in a direction away from the installation surface along the third axis, the fixing of the projector by the fixing member can be released. In addition, by moving the projector in a direction close to the installation surface along the third axis, the projector can be fixed to the installation surface by the fixing member. Therefore, the convenience of the projector can be improved.

[0374] The fixing member includes a protrusion, and the protrusion protrudes along the third axis, is inserted into the hole, and contacts the first contact surface, the second contact surface, the third contact surface, and the fourth contact surface.

[0375] According to such a structure, the protrusion of the fixing part fixed to the setting surface contacts the outer shell in four directions, namely, the first direction, the direction opposite to the first direction, the second direction, and the direction opposite to the second direction. Thus, the movement of the projector can be restricted when an external force in the direction in which each contact surface contacts the fixing part acts. Furthermore, since each contact surface contacts the protrusion, the movement of the projector can be restricted in the same manner even when an external force in a direction oblique to the direction in which each contact surface contacts the fixing part acts. Therefore, the movement of the projector on the setting surface can be restricted. Furthermore, by providing a cover component on the outer shell, a projector can be constructed whose movement on the setting surface can be restricted by the fixing part.
