The display panel 21 further includes a light source device 212 that causes the light guide plate to emit light.

[0052] The display panel 21 is a rectangular plate-shaped panel unit when viewed in the thickness direction (front-to-back direction). The panel body 210 is a rectangular panel with four sides. The panel body 210 is a resin molded product, for example, made of acrylic resin. The panel body 210 is translucent. A pattern 213 is formed on the front surface of the panel body 210 by painting.

[0053] The pattern 213 is a pattern formed with translucent green and white paint, and in this embodiment, it is a pictogram resembling a person. More specifically, the pattern 213 is a symbol indicating an emergency exit, with the color of the symbol being green and the background color of the symbol being white. Note that the pattern 213 is not limited to the pattern shown in Figure 1, but may also be, for example, an arrow-shaped symbol indicating the direction of evacuation, or the words "Emergency Exit" indicating an emergency exit.

[0054] The light guide plate is a molded resin product, for example, made of acrylic resin. The light guide plate is rectangular in shape and has a thickness along the front-to-back direction. The upper surface of the light guide plate is the incident surface to which light emitted from the light source device 212 enters, and the front surface of the light guide plate is the exit surface to which light that has entered the interior of the light guide plate exits.

[0055] The rear surface of the light guide plate is provided with a reflective and diffusing function that reflects and diffuses light so that light is emitted substantially uniformly from the entire front surface of the light guide plate. The reflective and diffusing function may be provided by forming an uneven diffusion pattern on the rear surface itself, or by laminating another member having a reflective and diffusing function (for example, a panel case 211) onto the rear surface of the light guide plate.

[0056] The light source device 212 comprises a light source such as a light-emitting diode, a rod-shaped light guide member, and a cover 2120 that houses the light source and the light guide member.

[0057] The light guide member is a rectangular bar that is elongated in the left-right direction. At least one of the left or right end faces of the light guide member constitutes the incident surface into which light from the light source enters, and the bottom surface of the light guide member constitutes the exit surface from which light is emitted. The light guide member is a resin molded product made of the same material as the light guide plate, for example, it is made of acrylic resin.

[0058] The cover 2120 is a rectangular box shape that is elongated in the left-right direction. The cover 2120 is made of a material such as resin that does not transmit light. The cover 2120 is a box shape with openings on the rear and bottom surfaces. Inside the cover 2120, the light guide member and the light source are housed so that the light source faces the left and right end faces of the light guide member.

[0059] Light incident from the light source onto the left and right incident surfaces of the light guide member is emitted downward from the entire left-right direction of the lower surface of the light guide member. As a result, light is incident on the entire left-right direction of the upper surface of the light guide plate, illuminating the entire front surface of the light guide plate and the panel body 210.

[0060] The panel case 211 is a case that supports the panel body 210 and the light guide plate. The panel case 211 is made of a material such as resin that does not transmit light. The panel case 211 is a flat rectangular box shape with the top and front surfaces open. The panel case 211 covers the panel body 210 and the light guide plate from both sides, the bottom, and the rear, and covers the lower edge and left and right edges of the front of the panel body 210 from the front.

[0061] After the unit consisting of the panel case 211, the panel body 210, and the light guide plate is attached to the mounting portions 234 of the left and right partition walls 232 and 233 of the support member 23 of the housing 20, the light source device 212 is attached to the panel case 211 and the upper wall 231 of the support member 23. As shown in Figure 3, the portion of the front of the housing 20 between the left and right partition walls 232 and 233 of the support member 23 is covered by the display panel 21.

[0062] The light source device 212 is attached to the support member 23, thereby electrically connecting the light source to the power supply unit 16 inside the housing 20. As a result, power for driving is supplied from the power supply unit 16 to the light source, causing the light source to emit light.

[0063] 2-6. Cover The cover 22 shown in Figures 1 and 2 is rectangular in shape when viewed from the front. Mounting fixtures 220 are provided at the left and right ends of the cover 22. The mounting fixtures 220 are detachably attached to the cover mounting portions 2030 on the left and right side walls 203 of the housing 20. The cover 22 is made of a material such as resin that does not transmit light.

[0064] The cover 22 is configured to cover the entire portion of the front of the housing 20 that is not covered by the display panel 21. The cover 22 has an opening 221 on its front so as to cover the panel case 211 and light source device 212 of the display panel 21 from the front. Only the image 213 of the display panel 21 is exposed through the opening 221 on the front of the cover 22.

[0065] 2-7.

The control module 31 is fixed to the upper surface of the fixing portion 322.

[0072] The support frame 320 has notched bearings 324 that receive the rotating shafts 303 and 304. The bearings 324 are provided on the left and right side frame sections 3201 and 3202, respectively. The shapes of the left and right bearings 324 and the rotating shafts 303 and 304 are set so that the rotating shafts 303 and 304 can rotate relative to the bearings 324, but the rotating shafts 303 and 304 cannot come out of the bearings 324.

[0073] The left and right bearings 324 are identical in shape. Figure 12 shows the right bearing 324. Each of the left and right bearings 324 is composed of a notch that is cut out downwards from the upper ends of the left and right side frame portions 3201 and 3202.

[0074] Each of the left and right bearings 324 includes an opening 3240 and a rear portion 3241 that is continuous with the opening 3240 and wider than the opening 3240. The rear portion 3241 is longer in the front-to-back direction than the opening 3240. In this embodiment, the opening 3240 is rectangular when viewed from the side and has a constant length in the front-to-back direction over the vertical direction. The rear portion 3241 is approximately circular when viewed from the side, and more specifically, it is a shape enclosed by a circular arc with a central angle greater than 180 degrees and an imaginary straight line connecting the ends of this arc.

[0075] A restricting portion 321 protrudes to the right from the portion of the right-side frame portion 3201 that is in front of the bearing 324. In this embodiment, the restricting portion 321 is a rectangular flat plate with thickness in the vertical direction. The restricting portion 321 is the part that restricts the rotation of the imaging unit 30. The restricting portion 321 has a first restricting surface 3211 that is struck when the angle adjustment portion 305 moves by a certain angle or more to one side in the rotational direction around the rotation axes 303, 304, and a second restricting surface 3212 that is struck when the angle adjustment portion 305 moves by a certain angle or more to the other side in the rotational direction. The rear surface of the restricting portion 321 forms the first restricting surface 3211, and the upper surface of the restricting portion 321 forms the second restricting surface 3212.

[0076] On the right side frame portion 3201, an extension portion 3203 is provided that extends upward from the upper part of the regulating portion 321. The extension portion 3203 is trapezoidal in shape when viewed from the side.

[0077] Multiple recesses 3204 are provided on the outer (i.e., right) side of the extension 3203. The multiple recesses 3204 are arranged on a virtual circle centered on the approximately circular inner portion 3241 of the bearing 324.

[0078] In this embodiment, each of the multiple recesses 3204 is an elliptical recess when viewed from the side. The multiple recesses 3204 are composed of four recesses 3204 of the same size and shape. In each of the four recesses 3204, the inner circumferential surface between the opening end (i.e., the right end) and the bottom surface is inclined with respect to the bottom surface such that the opening area is maximized at the opening end (i.e., the right end) of the recess 3204 and minimized at the bottom surface of the recess 3204. Therefore, a triangular protrusion 3205 is formed between the bottom surfaces of two recesses 3204 that are aligned in the circumferential direction. The two recesses 3204 that are aligned in the circumferential direction may be spaced apart in the circumferential direction, in which case the protrusion 3205 has a planar top surface.

[0079] The bottom surfaces of the four recesses 3204 are arranged at 5-degree intervals around the roughly circular inner portion 3241 of the bearing 324.

[0080] Of the right-side frame portion 3201, the second fixing portion 323 protrudes to the right from the front portion of the regulating portion 321. In this embodiment, the second fixing portion 323 is a rectangular flat plate with thickness in the vertical direction. The second fixing portion 323 is at the same vertical position as the fixing portion 322. A rectangular plate-shaped imaging device-side fixing portion 3230 extending downward is provided on the front edge of the second fixing portion 323.

[0081] A fixing portion 322 protrudes to the left from the upper end of the left side frame portion 3202. The fixing portion 322 is a rectangular flat plate with thickness in the vertical direction. A rectangular plate-shaped imaging device side fixing portion 3220 is provided at the front edge of the right end of the fixing portion 322, extending downward. The imaging device side fixing portion 3220 is in the same position in the front-to-back and vertical directions as the imaging device side fixing portion 3230 of the second fixing portion 323.

[0082] A through-hole 3221 is provided at the rear of the right end of the fixed portion 322, which accommodates the left rotation shaft 304 and protruding portion 306 of the imaging unit case 301. The through-hole 3221 penetrates the fixed portion 322 in the thickness direction (i.e., the vertical direction).

[0083] A fixing hole 3222 is provided at the rear of the left end of the fixing portion 322, into which one end in the longitudinal direction of a spring member 33, which is made of a coil spring, is fixed.

[0084] The imaging device side fixing portion 3220 of the fixing portion 322 and the imaging device side fixing portion 3220 of the second fixing portion 323 are positioned in front of a pair of left and right housing side fixing portions 209 provided on the lower wall portion 202 of the housing 20, and are fixed to the housing side fixing portions 209 with fasteners 12 such as screws.

[0085] The imaging unit 30 further has a projection 306 provided at the tip of the left rotating shaft 304. The projection 306 is rectangular and flat. The projection 306 is provided with a fixing hole 307 to which the other end in the longitudinal direction of the spring member 33 is fixed.

[0086] The left and right rotation axes 303 and 304 have the same cross-sectional shape perpendicular to the axial direction. Figure 12 shows the cross-sectional shape of the right rotation axis 303. Each of the left and right rotation axes 303 and 304 has a non-circular cross-sectional shape that minimizes the length in one direction. The length of the rotation axes 303 and 304 in the aforementioned one direction is less than or equal to the opening width (length in the front-to-back direction) of the opening 3240 of the bearing 324, and the length of the rotation axes 303 and 304 in directions other than the aforementioned one direction is greater than the opening width.

[0087] The cross-sectional shapes of the left and right rotation axes 303 and 304 are such that the length in the first direction (specifically the front-to-back direction in the diagram) is longer than the length in the second direction (specifically the up-and-down direction in the diagram), which is perpendicular to the first direction.

[0088] The lengths of the left and right rotation axes 303 and 304 in the first direction are the maximum outer dimensions of the left and right rotation axes 303 and 304, respectively, and the lengths of the left and right rotation axes 303 and 304 in the second direction are the minimum outer dimensions of the left and right rotation axes 303 and 304, respectively.

[0089] The lengths of the left and right rotation axes 303 and 304 in the first direction are less than or equal to the diameter of the inner portion 3241 of the bearing 324, and greater than the front-to-back width of the opening 3240 of the bearing 324. The lengths of the left and right rotation axes 303 and 304 in the second direction are less than or equal to the front-to-back width of the opening 3240 of the bearing 324.

[0090] Therefore, each of the left and right rotation axes 303 and 304 can pass through the openings 3240 of the left and right bearings 324 when the second direction is the front-to-back direction. In any orientation other than when the second direction is the front-to-back direction, each of the left and right rotation axes 303 and 304 cannot escape from the rear portion 3241 to the opening 3240 and is rotatably supported by the rear portion 3241.

[0091] As shown in Figures 9 and 12, the angle adjustment section 305 is plate-shaped with thickness in the left-right direction. The angle adjustment section 305 is fixed to the right-side rotation shaft 303 with a fastener 308 such as a screw. The angle adjustment section 305 has a base 3050 integrated with the right-side rotation shaft 303, an intermediate section 3051 continuous with the front side of the base 3050, and a tip section 3052 continuous with the front side of the intermediate section 3051.

[0092] The base 3050, the middle section 3051, and the tip section 3052 are progressively shorter in length in the vertical direction, in that order. The base 3050 has a semi-elliptical shape when viewed from the side, the middle section 3051 has a rectangular shape when viewed from the side, and the tip section 3052 has a triangular shape when viewed from the side. The rear end of the base 3050 is provided with a circular bulge 3059 that protrudes to the right when viewed from the side. A fixing device 308 is inserted through the center of the circle of the bulge 3059, and the angle adjustment part 305 is fixed to the right-side rotation shaft 303.

[0093] The base 3050, the intermediate section 3051, and the tip section 3052 have continuous upper surfaces that are flush with each other. The lower surfaces of the base 3050, intermediate section 3051, and tip section 3052 are progressively higher in this order. A stepped surface 3055 is formed between the lower surface 3053 of the base 3050 and the lower surface 3054 of the intermediate section 3051. A stepped surface 3057 is formed between the lower surface 3054 of the intermediate section 3051 and the lower surface 3056 of the tip section 3052. The lower surface 3053 of the base 3050 and the lower surface 3054 of the intermediate section 3051 are parallel to each other. The lower surface 3056 of the tip section 3052 is inclined such that the distance between it and the upper surface of the tip section 3052 becomes shorter towards the tip.

[0094] A cylindrical protrusion 3058 protrudes from the inner surface (left side) of the tip portion (i.e., the front end portion) of the tip portion 3052. The protrusion 3058 is sized to fit into one of the multiple recesses 3204.

[0095] As shown in Figure 9, the imaging unit case 301 has an upper case 302a and a lower case 302b. The imaging unit case 301 is provided with a finger rest 3026 on which a finger can be placed. As shown in Figures 9 and 11, the lower case 302b has a front lower wall portion 3020 whose front surface faces diagonally downward and forward, and a rear lower wall portion 3021 that extends diagonally upward and backward from the lower end of the front lower wall portion 3020, with its rear surface facing diagonally downward and backward. The lower case 302b further has a front upper wall portion 3022 that extends upward from the upper end of the front lower wall portion 3020, and a rear upper wall portion 3023 that extends upward from the upper end of the rear lower wall portion 3021. The lower case 302b further has left and right side walls 3024 that close off the space enclosed by the front lower wall 3020, the front upper wall 3022, the rear lower wall 3021, and the rear upper wall 3023 from the sides.

[0096] The front lower wall portion 3020, the rear lower wall portion 3021, the front upper wall portion 3022, and the rear upper wall portion 3023 are each rectangular flat plates. The left and right side wall portions 3024 are each flat plates.

[0097] An insertion hole 3025 through which the lens 300 passes is provided in the front lower wall portion 3020. A rib-shaped finger rest portion 3026 protruding diagonally downward and forward is provided at the lower end of the front lower wall portion 3020. The finger rest portion 3026 is provided at the lower end of the front lower wall portion 3020 so as to extend along its entire length in the left-right direction. Rotation shafts 303 and 304 protrude outward in the left-right direction from the rear upper part of the left and right side walls 3024.

[0098] The upper case 302a is combined with the lower case 302b so as to close the top opening of the lower case 302b. The imaging unit body is fixed to the underside of the upper case 302a. The imaging unit body is housed between the upper case 302a and the lower case 302b.

[0099] The imaging unit case 301 is positioned inside the support frame 320, and its left and right rotation axes 303 and 304 are supported by the left and right bearings 324 of the support frame 320. The angle adjustment unit 305 is positioned outside the support frame 320 (specifically on the right side) and is located opposite the right side frame portion 3201 of the support frame 320. The protrusion 3058 of the angle adjustment unit 305 is inserted into one of the multiple recesses 3027 of the right side frame portion 3201.

[0100] As shown in Figure 10, a spring member 33 is connected to the fixing hole 307 of the protruding portion 306 at the tip of the left rotating shaft 303 of the imaging unit case 301 and to the fixing hole 3222 of the fixing portion 322 of the support member 23. As a result, a leftward biasing force is applied to the imaging unit case 301 by the spring member 33, and the convex portion 3058 of the angle adjustment portion 305 elastically presses against the bottom surface of one of the multiple recesses 3204.

[0101] The imaging unit case 301 is angle-adjustable within the range where the protrusion 3058 of the angle adjustment section 305 fits within the range from the lowest recess 3027 to the highest recess 3027 of the four recesses 3027. The angle of the imaging unit case 301 can be adjusted by hooking a finger onto the rib-shaped finger rest 3026.

[0102] In this embodiment, when the imaging unit case 301 is rotated so that the protrusion 3058 is positioned above the uppermost recess 3027, the stepped surface 3055 of the angle adjustment unit 305 contacts the rear surface of the restricting unit 321 (i.e., the first restricting surface 3211), thereby restricting rotation. Also, when the imaging unit case 301 is rotated so that the protrusion 3058 is positioned below the lowermost recess 3027, the lower surface 3054 of the intermediate part 3051 of the angle adjustment unit 305 contacts the upper surface of the restricting unit 321 (i.e., the second restricting surface 3212), thereby restricting rotation. Therefore, in this embodiment, the imaging unit case 301 can be angle-adjusted by the amount of the four recesses 3204, i.e., within a range of 15 degrees (5 degrees x 3).

[0103] When the imaging unit case 301 is rotated, the imaging unit case 301 moves to the right against the biasing force of the spring member 33 when the protrusion 3058 of the angle adjustment unit 305 passes over the protrusion 3205 located between two adjacent recesses 3204 in the circumferential direction. After the protrusion 3058 has passed over the protrusion 3205, the imaging unit case 301 moves to the left due to the biasing force of the spring member 33. When the protrusion 3058 of the angle adjustment unit 305 passes over the protrusion 3205, the resistance felt by the finger hooked on the rib-shaped finger rest 3026 increases, making it intuitively clear that the protrusion 3058 has moved between the two recesses 3204 aligned in the circumferential direction.

[0104] In the imaging device 3 of this embodiment, the imaging unit case 301 can be angle-adjusted within a range of 15 degrees in the vertical direction, thereby expanding the effective vertical field of view of the imaging device 3.

[0105] As shown in Figures 8 and 9, the control module 31 includes a control circuit 310 for controlling the imaging unit 30 and a module case 311 for housing the control circuit 310. A card slot 312 into which an SD card 15 can be inserted is mounted on a part of the control circuit 310. In this embodiment, the card slot 312 opens to the right.

[0106] In this embodiment, the module case 311 is a rectangular cylindrical shape with openings at both the top and bottom. The module case 311 is formed by combining two parts of the same shape, one at the front and one at the back.

[0107] An opening 313 is provided in the right side wall of the module case 311, in the portion to the right of the card slot 312. The module case 311 is attached to the imaging device support member 24 such that a portion of the card insertion guide portion 25 fits into the opening 313. An opening 314 is provided in the left side wall of the module case 311, at the same vertical position as the opening 313.

[0108] The control circuit 310 is connected to the communication line connection section 13 via a wire 14 (see Figure 3). As shown in Figure 4, the wire 14 passes through the upper opening of the module case 311 and is connected to the connector 315 mounted on the control circuit 310. Here, the space above the module case 311 is empty space, making it easy to route the wire 14. Also, if the wire 14 is a commercially available communication wire, the length of the communication wire can be easily accommodated in the space above the module case 311. The control circuit 310 and the control circuit 10 that controls the emergency light body 2 are separate components.

[0109] The lower end of the module case 311 is fixed to the upper surface of the fixing portion 322 of the support portion 32. This integrates the control module 31 and the imaging unit 30.

[0110] As shown in Figure 5, the imaging device 3 is attached to the housing 20 together with the imaging device support member 24, with the module case 311 attached to the imaging device support member 24 on the outside of the housing 20.

[0111] As shown in Figure 4, the imaging device 3 is attached to the housing 20 together with the imaging device support member 24 such that the portion of the imaging unit 30 below the support frame 320 protrudes downward from the insertion portion 208 of the lower wall portion 202 of the housing 20. At this time, the imaging device 3 and the imaging device support member 24 are attached to the housing 20 by hooking the imaging device support member 24 onto the multiple mounting portions 234 of the support member 23.

[0112] At this time, the imaging device 3 has its imaging device side fixing parts 3220 and 3230 of the fixing part 322 and second fixing part 323 positioned in front of a pair of left and right housing side fixing parts 209 provided on the lower wall part 202 of the housing 20, and is fixed to the housing side fixing parts 209 with fasteners 12 such as screws. This allows the lower wall part 202 having the insertion part 208 to be reinforced by the support part 32 of the imaging device 3.

[0113] After the imaging device 3 is mounted to the housing 20, the display panel 21 and cover 22 are attached to the housing 20.

[0114] With the imaging device 3 mounted on the housing 20, the lens 300 is positioned below the lower wall portion 202. The lens 300 is angled diagonally downward and forward. The lens 300 is tilted at an angle of, for example, 37.5 to 52.5 degrees with respect to the horizontal, including the angle adjustment range provided by the angle adjustment portion 305.

[0115] 3. Effects Next, we will explain the operation and effects of the guide light 1 with imaging device described above.

[0116] In the guide light with imaging device 1, as shown in Figures 1 and 2, at least a part of the imaging device 3 is provided inside the housing 20 of the guide light body 2, making it easier to miniaturize the guide light with imaging device 1.

[0117] Furthermore, in the guide light with imaging device 1, the part of the imaging device 3 that is exposed to the outside of the housing 20 (i.e., the imaging unit case 301 of the imaging unit 30) is provided to be angle-adjustable, so the imaging angle can be adjusted by operating this part from the outside of the housing 20. Therefore, the guide light with imaging device 1 is easy to miniaturize and the imaging angle can be easily adjusted.

[0118] In the guide light with imaging device 1, the imaging unit case 301 can be rotated by placing a finger on the ribbed finger rest 3026, making rotation operation easy.

[0119] In the guided exit sign 1 with an imaging device, the protrusion 3058 of the angle adjustment section 305 and the multiple recesses 3204 of the support frame 320 (see Figure 9) are located inside the housing 20 and are not exposed to the outside of the housing 20. Therefore, in the guided exit sign 1 with an imaging device, the structure for adjusting the angle of the imaging section 30 is not exposed, and the appearance of the guided exit sign 1 with an imaging device is not easily compromised.

[0120] In the guided exit sign 1 with an imaging device, as shown in Figure 12, the two restricting surfaces 3211 and 3212 of the restricting section 321 prevent the angle adjustment section 305 from rotating beyond a certain angle (specifically, rotation outside the range in which the protrusions 3058 are engaged with the multiple recesses 2304). Therefore, in the guided exit sign 1 with an imaging device, the exposure of the structure for angle adjustment of the imaging section 30 is minimized, while preventing the imaging section 30 from rotating beyond a certain angle.

[0121] In the guided light with imaging device 1, the spring member 33 (see Figure 10) allows force to be applied to the imaging unit 30 in the direction that the angle adjustment unit 305 approaches the support frame 320, so that the protrusion 3058 can be elastically pressed against one of the multiple recesses 3024. Therefore, in the guided light with imaging device 1, it is easy to maintain the state in which the protrusion 3058 of the angle adjustment unit 305 is locked into any one of the multiple recesses 3024, and the imaging angle is easily stabilized. In addition, in the guided light with imaging device 1, when the imaging unit case 301 is rotated and the protrusion 3058 of the angle adjustment unit 305 moves over the protrusion 3205 (see Figure 12) between two adjacent recesses 3204, the resistance felt by the finger rotating the imaging unit case 301 increases. Therefore, it is easy for the user to understand that the angle of the imaging unit case 301 has been adjusted by the amount of one recess 3204 (i.e., 5 degrees in this embodiment).

[0122] In the guide light with imaging device 1, as shown in Figure 4, the imaging device side fixing parts 3220 and 3230 of the support part 32 are fixed to the lower wall part 202 of the housing 20, and since the support part 32 is less likely to shift position, the imaging unit 30 can be easily rotated.

[0123] In the guide light with imaging device 1, the part of the imaging device 3 that is exposed to the outside of the housing 20 (i.e., the imaging unit case 301 of the imaging unit 30) can be rotated, so the angle of the imaging device 3 can be adjusted without removing the cover 22 and the display panel 21 from the housing 20.

[0124] 4. Variations The following describes some variations of the guide light with imaging device 1 described above. The variations shown below can be combined as appropriate.

[0125] The imaging device 3 is provided inside the housing 20 such that a portion of it is exposed to the outside of the housing 20, and this portion is provided so as to be angle-adjustable; it is not limited to the structure shown in Figure 9, etc.

[0126] The locking structure (multiple recesses 3204 and protrusions 3058) provided on the opposing surfaces of the support frame 320 and the angle adjustment section 305 is not limited to the structure shown in Figure 12, etc. For example, the support frame 320 may be provided with multiple protrusions 3058 and the angle adjustment section 305 may be provided with one recess 3204. Alternatively, the support frame 320 may be provided with one protrusion 3058 and the angle adjustment section 305 may be provided with multiple recesses 3204. Furthermore, the support frame 320 may be provided with one recess 3204 and the angle adjustment section 305 may be provided with multiple protrusions 3058.

[0127] The locking structure (multiple recesses 3204 and protrusions 3058) does not have to be located inside the housing 20, but may be located outside the housing 20.

[0128] The support portion 32 does not necessarily have a restricting portion 321 that restricts the rotation of the angle adjustment portion 305 beyond a certain angle.

[0129] The imaging device 3 does not necessarily have a spring member 33 that applies force to the imaging unit 30 in the direction that the angle adjustment unit 305 approaches the support frame 320. For example, the angle adjustment unit 305 may be provided in an elastically deformable manner such that the convex portion 3058 elastically presses against the concave portion 3204.

[0130] The angle of view of the lens 300 in the first direction (vertical direction in this embodiment) may be greater than or equal to the angle of view of the lens 300 in the second direction (horizontal direction in this embodiment).

[0131] The finger rest portion 3026 is not limited to a rib extending in the left-right direction, but may also be a groove extending in the left-right direction, or may be composed of multiple protrusions or multiple recesses or a combination thereof. The finger rest portion 3026 is not limited to the lower end of the front surface of the front lower wall portion 3020 of the imaging unit case 301, but may also be provided on the rear surface of the rear lower wall portion 3021 or on the left-right outer surfaces of the left and right side wall portions 3024. The imaging unit case 301 is not required to be provided with a finger rest portion 3026 on which a finger can be placed.

[0132] The rotating axes 303 and 304 only need to have a non-circular cross-sectional shape that minimizes their length in one direction, and are not limited to the shapes shown in Figure 11.

[0133] The rotating shafts 303 and 304 are not limited to being non-circular; they may also have a circular cross-sectional shape, in which case the bearing 324 may have a round hole.

[0134] (summary) As described above in the embodiment and its modified form, the guide light with imaging device (1) of the first embodiment has the following configuration.

[0135] In other words, the first embodiment of the guide light with imaging device (1) comprises a guide light body (2) having a housing (20), and an imaging device (3) provided inside the housing (20) such that a portion of it is exposed to the outside of the housing (20). The portion is provided so as to be angle-adjustable.

[0136] In the first embodiment of the guide light with imaging device (1) having the above configuration, at least a part of the imaging device (3) is provided inside the housing (20) of the guide light body (2), so the guide light with imaging device (1) can be made smaller. Furthermore, in this guide light with imaging device (1), the part of the imaging device (3) that is exposed to the outside of the housing (20) is provided to be angle-adjustable, so the imaging angle can be adjusted by operating this part from the outside of the housing (20). Therefore, this guide light with imaging device (1) is easy to miniaturize and the imaging angle can be easily adjusted.

[0137] Furthermore, as described above in the embodiment and its modified form, the second embodiment of the guide light with imaging device (1) additionally includes the following configuration in addition to the configuration of the first embodiment.

[0138] In other words, in the second embodiment of the guide light with imaging device (1), the imaging device (3) includes an imaging unit (30) which includes a lens (300) and constitutes a part thereof, and a control module (31) which is arranged inside the housing (20) and controls the imaging unit (30). The imaging device (3) further includes a support unit (32) which supports the imaging unit (30) in an angle-adjustable manner.

[0139] In the second embodiment of the guide light with imaging device (1) having the above configuration, the imaging unit (30) of the imaging device (3), including the lens (300), is exposed to the outside of the housing (20) and its angle can be adjusted, making it easy to adjust the imaging angle. In addition, in the second embodiment of the guide light with imaging device (1), the control module (31) that controls the imaging unit (30) is located inside the housing (20), making it easier to miniaturize the guide light with imaging device (1).

[0140] Furthermore, as described above in one embodiment and its modified form, the guide light with imaging device (1) of the third embodiment additionally includes the following configuration in addition to the configuration of the second embodiment.

[0141] In other words, in the third embodiment of the guide light with imaging device (1), the imaging unit (30) includes an imaging unit body including a lens (300) and an imaging unit case (301) that houses the imaging unit body such that the lens (300) is exposed. The imaging unit (30) further includes a rotating shaft (303) protruding from the imaging unit case (301) and an angle adjustment unit (305) provided at the tip of the rotating shaft (303).
