It is something to try. Embodiments of the present invention will be described below.

[Configuration of HMD]
A first embodiment of the present invention will be described. First, the configuration of the HMD including the camera unit fixing structure according to the present embodiment will be described with reference to FIG. As shown in FIG. 1, the HMD 1 according to the present embodiment uses the retina of the eye Y of the user of the HMD 1 (hereinafter simply referred to as “user”) as the projection target, and makes the scanned laser light incident from the pupil. By projecting onto the retina, the user can visually recognize the image. In other words, the HMD 1 is a retinal scanning type image display device that allows a user to recognize an afterimage of light scanned on the retina as an image by irradiating the user's retina while scanning weak light at high speed. .

  The HMD 1 includes a control unit 2, a projection unit 3 as a projection device, and a glasses-type frame 4. The control unit 2 emits laser light having an intensity corresponding to the image signal as image light. The control unit 2 includes a storage unit, and forms an image signal based on information stored in the storage unit. The control unit 2 emits laser light having an intensity corresponding to the formed image signal to the transmission cable 5 as image light.

  Specifically, the control unit 2 includes a control unit 2a that controls main operations of the HMD 1 and a light source unit 2b that generates laser light as image light. The control unit 2a controls the HMD 1 by executing a predetermined process in accordance with a control program stored in a storage unit built in the control unit 2. The control unit 2a includes various functional parts such as a CPU, flash memory, RAM, VRAM, and a plurality of input / output interfaces connected by a data communication bus, and transmits and receives various types of information via the bus. The control unit 2 a is a part that forms an image signal in the control unit 2. The control unit 2a supplies the formed image signal to the light source unit 2b.

  The light source unit 2b reads out image information in pixel units from the image signal supplied from the control unit 2a, and R (red), G (green), and B (blue) based on the read out pixel unit image information. Laser light whose intensity is modulated for each color is generated and emitted. Accordingly, the light source unit 2b has a configuration for generating laser light of each color, such as a light source of each color of R (red), G (green), and B (blue). Laser light emitted from the light source unit 2 b is emitted to the transmission cable 5 as image light from the control unit 2.

  The image light emitted from the control unit 2 is transmitted to the projection unit 3 through the transmission cable 5. The transmission cable 5 includes an optical fiber cable that transmits the image light emitted from the control unit 2 to the projection unit 3.

  The projection unit 3 scans the image light intensity-modulated for each of R (red), G (green), and B (blue) colors in the control unit 2 in a two-dimensional direction, and applies it to the user's eye Y. Make it incident. That is, the projection unit 3 scans the image light transmitted by the transmission cable 5 so that the user can recognize it as a display image.

  Specifically, the projection unit 3 scans the laser light in a predetermined direction for displaying an image, and an optical system for collimating the laser light generated by the control unit 2 and incident via the transmission cable 5. And a relay optical system that relays laser light between the respective units in the projection unit 3.

  The projection unit 3 includes a half mirror 6 for causing image light to enter the user's eye Y. The half mirror 6 is provided so as to be positioned in front of the user's eye Y. The projection unit 3 reflects the emitted image light L <b> 1 by the half mirror 6 and makes it incident on the user's eye Y. The half mirror 6 transmits the external light L2 and makes it incident on the user's eye Y. Therefore, the user can visually recognize the image by the image light L1 superimposed on the background recognized by the external light L2.

  As described above, the HMD 1 of the present embodiment is a see-through type that projects the image light L1 emitted from the projection unit 3 while scanning the user's eye Y while transmitting the external light L2. Note that the HMD according to the present invention need not be a see-through type.

  The frame 4 is a portion that supports the projection unit 3 and is attached to the user's head. The frame 4 supports the projection unit 3 so that image light can be scanned onto the user's eye Y by the projection unit 3 as described above while being mounted on the user's head. In the HMD 1 of the present embodiment, the projection unit 3 is attached to the left side of the user with the frame 4 mounted on the head with respect to the frame 4.

  The HMD 1 includes a camera unit 7. As shown in FIGS. 2 and 3, the camera unit 7 includes an imaging device 8 that images the outside such as a user's surroundings, and a casing 9 that houses the imaging device 8. The imaging device 8 is, for example, a CCD (Charge Coupled Device) camera, a CMOS (Complementary Metal Oxide Semiconductor) camera, or the like.

  The imaging device 8 is connected to the control unit 2a (see FIG. 1) of the control unit 2 via a cable. The image data acquired by the imaging device 8 is input to the control unit 2a through a cable. The control unit 2a generates an image signal based on the image data supplied from the imaging device 8. That is, the image signal supplied from the control unit 2 a to the light source unit 2 b includes an image signal generated based on the image data supplied from the imaging device 8. Therefore, the image picked up by the image pickup device 8 is projected onto the user's eyes by the projection unit 3 and recognized by the user.

  The casing 9 accommodates the imaging device 8 and constitutes the exterior of the camera unit 7. The casing 9 has an opening 9 a that allows the imaging surface of the imaging device 8 to face the outside of the casing 9. The opening 9 a is formed in the front surface 9 b of the casing 9.

  As described above, the HMD 1 according to the present embodiment includes the camera unit 7 and can capture the outside world such as the surroundings of the user. The camera unit 7 is used in a state where it is supported by the glasses-type frame 4 in the HMD 1. Hereinafter, a fixing structure of the camera unit 7 according to the present embodiment (hereinafter referred to as “camera fixing structure”) will be described.

  The camera fixing structure of this embodiment is for fixing the camera unit 7 to a spectacle-type frame 4 to be mounted on the user's head. In the description of the camera fixing structure, first, the configuration of the frame 4 to which the camera unit 7 is fixed will be described.

  As shown in FIGS. 1 to 3, the frame 4 is configured in a spectacle shape and supports the projection unit 3 as described above. The frame 4 includes a pair of temple portions 11 that sandwich the user's face from the left and right sides, a front portion 12, and a connecting portion 13 that connects one end side of the pair of temple portions 11 to the front portion 12.

  The temple part 11 bulges outward once from the front side which is connected to the front part 12 to the rear side which is the opposite side so as to follow the user's head. It has a curved shape as a whole (see FIG. 1).

  The front portion 12 has a generally bowed shape in a plan view so that the frame 4 is convex toward the front of the user when the frame 4 is attached to the user. That is, the front portion 12 has a shape that is gently curved so that the side to which the pair of temple portions 11 are connected is the left and right ends, and the central portion is convex on the front side opposite to the side where the temple portions 11 extend. (See FIGS. 1 and 2)

  The front portion 12 is formed in a plate shape and has a shape that is bowed along a plane perpendicular to the plate thickness direction. Further, the front portion 12 has a shape that gently curves in the thickness direction so that the central portion is slightly depressed downward (see FIG. 3).

  The connecting part 13 constitutes a part for connecting the temple part 11 and the front part 12. The connecting portion 13 is provided at both left and right end portions of the front portion 12. The connecting portion 13 is a portion formed so as to protrude from the front portion 12 along the direction in which the temple portion 11 extends from the front portion 12.

  The camera unit 7 is supported on the front portion 12 of the frame 4 with respect to the frame 4 of the HMD 1 having the above configuration. As shown in FIG. 2, the casing 9 of the camera unit 7 is supported by the frame 4 and has a shape along an arcuate shape along the front portion 12 in plan view. Similarly, in a plan view, the casing 9 has substantially the same size as the length of the front portion 12 in the left-right direction, and has a size that covers the entire front portion 12 while being supported by the frame 4.

  In the camera unit 7, the imaging device 8 is disposed so as to face front at a substantially central position on the left and right sides of the casing 9. Therefore, the opening 9a that allows the imaging surface of the imaging device 8 to face the outside of the casing 9 is the front side at a position above the user's eyebrows while the frame 4 supporting the camera unit 7 is attached to the user. Open to. Thereby, a user's visual field and the visual field which the imaging device 8 image | photographs substantially correspond. Then, the user images the outside world in front of the user with the camera unit 7.

  In the camera fixing structure, the camera unit 7 is detachably fixed to the frame 4 by a mounting portion 10 of the camera unit 7. As shown in FIGS. 2 and 3, in the camera fixing structure of the present embodiment, the mounting portion 10 fixes the camera unit 7 to the frame 4 at both left and right end portions of the front portion 12.

  Specifically, as shown in FIGS. 2 and 3, the attachment portion 10 fixes the camera unit 7 to the frame 4 at both left and right ends of the front portion 12 of the frame 4. For this reason, the attachment portion 10 is provided on the bottom surface 9 c side of the casing 9 that faces the upper surface 12 a of the front portion 12 in a state where the camera unit 7 is supported by the frame 4 at both left and right ends of the casing 9.

  In the camera fixing structure of this embodiment, the mounting portion 10 of the camera unit 7 is configured by fixing a fixing component 20 separate from the casing 9 to the camera unit 7.

  With reference to FIGS. 4 to 10, the fixing component 20 constituting the mounting portion 10 of the camera unit 7 will be described. As shown in FIGS. 4 to 10, the fixing component 20 includes a substantially rectangular plate-shaped base portion 21 and a pair of locking piece portions 22 that are locked in a state where the front portion 12 of the frame 4 is sandwiched.

  The base 21 is a part fixed to the camera unit 7. The fixed component 20 is fixed to the casing 9 of the camera unit 7 by a fastener such as a screw. For this reason, a hole 21 a for a fastener is formed in the base 21 of the fixed component 20. The hole 21 a is formed at a substantially central part of the base 21 so as to penetrate the plate-like base 21.

  The base 21 is sandwiched between the frame 4 and the camera unit 7 in a state where the camera unit 7 is supported by the frame 4. Specifically, the base portion 21 is sandwiched between the upper surface 12 a of the front portion 12 of the frame 4 and the bottom surface 9 c of the casing 9.

  For this reason, a hole 9e for a fastener for fixing the fixing component 20 to the casing 9 is formed in the bottom 9d forming the bottom surface 9c in the casing 9 (see FIG. 5). That is, the hole 9e receives the fastener in a state where it communicates with the hole 21a formed in the base 21. Thus, the fixing component 20 uses the hole 21a formed in the base 21, and is fixed to the casing 9 of the camera unit 7 by a fastener such as a screw.

  The locking piece portion 22 is a wall-shaped portion formed so as to protrude from the base portion 21 toward the lower side in a substantially vertical direction with respect to the base portion 21. The pair of locking pieces 22 sandwich the front portion 12 from the front-rear direction of the spectacle-shaped frame 4. For this reason, one locking piece 22 is provided at the front end of the base 21, and the other locking piece 22 is provided at the rear end of the base 21. That is, the pair of locking piece portions 22 are plate-like portions that are substantially parallel to each other and face in the front-rear direction.

  The pair of locking pieces 22 oppose each other with an interval at which the front portion 12 of the frame 4 can be fitted. A space between the inner side surface 22a facing each other and the lower side surface 21b of the base portion 21 in the pair of locking piece portions 22 is a space in which the front portion 12 of the frame 4 is held (see FIG. 5). Here, the lower side surface 21 b of the base portion 21 is a surface facing the upper surface 12 a of the front portion 12. Each locking piece 22 locks the front portion 12 located in a space between the inner side surface 22a and the lower side surface 21b of the base portion 21 (hereinafter referred to as “frame holding space”). A locking claw 23 is included.

  The locking claw 23 forms a locking surface 23 a that is a surface that is substantially perpendicular to the inner side surface 22 a of the locking piece portion 22 and faces upward. The locking claw 23 forms a stepped portion that protrudes toward the opposing locking piece portion 22 at the lower end portion of the locking piece portion 22 that is a wall-shaped portion.

  The locking claw 23 forms a gap (hereinafter referred to as “inter-claw gap”) narrower than the width of the frame 4 together with the locking claw 23 of the opposing locking piece portion 22. Here, the width of the frame 4 is the dimension of the front portion 12 in the front-rear direction. As shown in FIG. 5, the gap between the claws is a dimension between the pair of opposing locking claws 23 (see reference numeral D <b> 1) and is smaller than the dimension in the front-rear direction of the frame holding space. In other words, the dimension of the gap between the claws (see reference numeral D1) is narrower than the interval between the inner side surfaces 22a of the pair of opposing locking pieces 22.

  The front and rear dimensions of the front portion 12 held in the frame holding space are such that the front and rear ends of the front portion 12 are located on the inner side surface 22a with respect to the interval between the inner side surfaces 22a of the pair of opposing locking pieces 22. It is a dimension that is substantially in contact, or a dimension that leaves a slight gap between the front and rear ends of the front portion 12 and the inner side surface 22a. Similarly, the front-rear dimension of the front portion 12 is larger than the dimension of the gap between the claws (see reference sign D1).

  Thus, the camera unit 7 is fixed to the frame 4 in a state where the front portion 12 is sandwiched from the front-rear direction by the pair of locking pieces 22 having the locking claws 23. The pair of locking pieces 22 are fitted to the front portion 12 in the frame holding space between the locking pieces 22 through the inter-nail gap by elastic deformation due to the pressing action on the front portion 12. 12 is held in a state of being sandwiched.

  Specifically, as shown in FIG. 10, relative movement of the fixed component 20 and the frame 4 with respect to the front portion 12 located outside the frame holding space of the fixed component 20 and below the base portion 21. Thus, the fixed component 20 is pressed (see arrow A). As a result, as shown in FIG. 11, the fixing component 20 is elastically deformed so that the gap between the claws of the pair of locking pieces 22 is widened, thereby allowing the front portion 12 to enter the frame holding space. The

  More specifically, the dimension of the gap between the claws between the pair of locking pieces 22 is smaller than the dimension of the front portion 12 in the front-rear direction. For this reason, in a state where the fixed component 20 is not deformed, the front portion 12 cannot enter the frame holding space from the gap between the claws. Therefore, the fixing component 20 having the pair of locking piece portions 22 is elastically deformed by a pressing action on the front portion 12 to allow the front portion 12 to enter the frame holding space. Therefore, the elastic deformation that occurs in the fixed component 20 when the front portion 12 is fitted into the frame holding space is mainly about the portion of the locking piece portion 22.

  Then, from the state in which the fixed component 20 is elastically deformed by pressing the fixed component 20 against the front portion 12, the front portion 12 gets over the locking claw 23 and reaches above the locking claw 23 by further pressing, so that the front portion 12 is fitted into the frame holding space and is locked by the locking surface 23a of the locking claw 23 between the pair of locking pieces 22 (see FIG. 5).

  In order to promote elastic deformation of the fixed component 20 due to the pressing action of the fixed component 20 against the front portion 12, the corner portion on the tip (lower end) of the locking piece portion 22 and facing the other locking piece portion 22. A chamfered portion 22b is formed. The chamfered portions 22b of the pair of locking piece portions 22 are portions that form slopes that gradually narrow the size of the gap between the claws from the lower side to the upper side.

  Thus, the fixed component 20 has a structure that is elastically deformed and snapped when the front portion 12 of the frame 4 is fitted. The mounting portion 10 formed by fixing such a fixing component 20 to the casing 9 of the camera unit 7 is provided in the camera unit 7 and is at least a pair of engagements facing each other with an interval in which the frame 4 can be fitted. As a stop piece, it has a pair of latching piece part 22 formed in the fixed component 20. As shown in FIG. The locking piece portion 22 includes a locking claw 23 that forms a gap between the claws narrower than the width of the front portion 12 of the frame 4 together with the opposing locking piece portion 22.

  And the attachment part 10 fits the flame | frame 4 between the latching piece parts 22 which mutually oppose through the clearance gap between claws by the elastic deformation of the latching piece part 22 by the press action to the flame | frame 4. FIG. Thereby, the attaching part 10 fixes the camera unit 7 to the flame | frame 4 so that attachment or detachment is possible in the state which pinched | interposed the flame | frame 4 by the latching piece part 22 which mutually opposes. As described above, the camera unit 7 having the mounting portion 10 constituted by the fixed component 20 is fixed to the frame 4 by the mounting portion 10 by being pressed against the front portion 12 of the frame 4.

  The fixed component 20 constituting the mounting portion 10 is configured as a component that causes elastic deformation necessary for fitting to the frame 4 by being integrally formed of a resin material such as ABS resin or polyacetal. However, the material constituting the fixed component 20 is not limited as long as the elastic deformation necessary for fitting the fixed component 20 to the frame 4 can be obtained.

  Moreover, the fixed component 20 has the press piece part 24 for pressing the front part 12 from the upper surface 12a side. The pressing piece portion 24 is a substantially rectangular plate-shaped portion that protrudes from the side surfaces of a pair of opposed piece portions other than the side portion where the opposed pair of locking piece portions 22 of the substantially rectangular plate-shaped base portion 21 are formed. . That is, in the present embodiment, the pressing piece portion 24 is formed to protrude in a substantially rectangular plate shape on the left and right side surfaces of the base portion 21. Therefore, the fixed component 20 of the present embodiment has two pressing piece portions 24, and the two pressing piece portions 24 are formed in a wing shape with respect to the base portion 21.

  The pressing piece portion 24 is inclined so as to gradually fall from the base side, which is the side connected to the base portion 21, to the distal end side in the protruding direction. The pressing piece portion 24 presses the front portion 12 with the lower surface facing the upper surface 12a of the front portion 12 as a pressing surface 24a. That is, the pressing piece portion 24 presses the front portion 12 in a state where the pressing surface 24 a is in contact with the upper surface 12 a of the front portion 12.

  The pressing piece portion 24 presses the front portion 12 by its elasticity. The front portion 12 pressed by the pressing piece portion 24 is locked by the locking claw 23 of the locking piece portion 22. That is, the front portion 12 pressed by the pressing piece portion 24 is sandwiched between the pressing surface 24 a of the pressing piece portion 24 and the locking surface 23 a of the locking claw 23.

  Therefore, the dimension between the pressing surface 24a of the pressing piece portion 24 and the locking surface 23a of the locking claw 23 (see FIG. 5, reference numeral D2) is the thickness of the front portion 12 in the fixed component 20 in the natural state. Smaller than dimensions. As a result, the pressing piece 24 is pushed up by the front portion 12 being fitted into the frame holding space and elastically deformed, and the front portion 12 held in the frame holding space is connected to the locking claw 23. (See arrow P in FIG. 8).

  In this way, the mounting portion 10 constituted by the fixing component 20 having the pressing piece portion 24 locks the frame 4 with elasticity in a state where the frame 4 is fitted between a pair of locking piece portions 22 facing each other. A pair of pressing pieces 24 formed in the fixed component 20 is provided as a pressing piece that is pressed toward the side 23 and sandwiches the frame 4 with the locking claw 23. In the present embodiment, the mounting portion 10 constituted by the fixed component 20 includes two pressing piece portions 24, but the number of pressing piece portions 24 is not limited and may be one or three or more.

  Here, a modified example of the pressing piece portion 24 will be described. First, a first modification of the pressing piece 24 will be described with reference to FIG. As shown in FIG. 12, the pressing piece portion 24 according to this example has a protruding piece portion 24 b. The protruding piece portion 24 b is a portion that protrudes upward at the distal end portion of the pressing piece portion 24. The projecting piece 24b has a shape such that the tip of the plate-like pressing piece 24 is bent in a substantially right angle direction.

  As described above, the projecting piece portion 24b functions as a stopper that prevents the pressing piece portion 24 from elastically deforming more than necessary in the pressing piece portion 24 that presses the front portion 12. The projecting piece portion 24 b abuts against the bottom surface 9 c of the casing 9 of the camera unit 7, thereby restricting the pressing piece portion 24 from being elastically deformed in the direction of increasing the pressing force against the front portion 12. Here, regarding the elastic deformation of the pressing piece portion 24, the direction in which the pressing piece portion 24 increases the pressing force against the front portion 12 is the distance between the pressing surface 24 a of the pressing piece portion 24 and the locking surface 23 a of the locking claw 23. Is the opening direction.

  As described above, since the pressing piece portion 24 has the protruding piece portion 24b, excessive bending of the pressing piece portion 24 can be suppressed, and the elasticity of the pressing piece portion 24 is reduced by reaching the elastic limit. Can be prevented. That is, according to the projecting piece portion 24b, the elasticity of the pressing piece portion 24 can be maintained, and resistance to the function of the pressing piece portion 24 can be improved.

  Next, a second modification of the pressing piece 24 will be described with reference to FIG. As illustrated in FIG. 13, the pressing piece portion 24 according to this example includes a bending portion 24 c. The bending portion 24 c is a portion having a thinner plate thickness than other portions of the pressing piece portion 24.

  The bending portion 24c is bent at a midway portion in the protruding direction of the pressing piece portion 24 so as to form a portion protruding linearly along the width direction of the pressing piece portion 24 from the upper surface of the pressing piece portion 24. It has a shape like Therefore, in this example, the pressing piece part 24 has the bending part 24c, and the pressing piece part 24 has the external shape which becomes a substantially hat shape by the front view shown in FIG. Here, the width direction of the pressing piece 24 is a direction perpendicular to the protruding direction from the base 21 of the pressing piece 24 in the plan view of the pressing piece 24 shown in FIG. 6, for example, in FIG. The vertical direction.

  Thus, since the pressing piece portion 24 has the bending portion 24c, the pressing piece portion 24 can be easily bent. That is, the bending portion 24 c is a portion that partially reduces the rigidity in the pressing piece portion 24. According to the bending portion 24c, the pressing piece portion 24 is easily bent, so that the camera unit resists the pressing force by the pressing piece portion 24 necessary for fitting the front portion 12 into the frame holding space in the fixed component 20. The force which presses 7 can be made small. As a result, the burden of fixing work of the camera unit 7 performed by pressing the camera unit 7 against the frame 4 can be reduced.

  Further, the fixed component 20 includes a holding piece portion 25 for holding a cable connected to the imaging device 8 of the camera unit 7 with the casing 9. The holding piece portion 25 is a wall-shaped portion formed so as to protrude in the substantially vertical direction with respect to the base portion 21 from the base portion 21 toward the upper side. The holding piece 25 is provided at the rear end of the base 21. Therefore, the holding piece portion 25 is formed to be substantially L-shaped with the base portion 21 in a side view of the fixed component 20. The holding piece portion 25 has substantially the same width dimension as the locking piece portion 22.

  As shown in FIG. 5, the holding piece 25 forms a space for holding the cable 18 connected to the imaging device 8 (hereinafter referred to as “cable holding space”) with the casing 9 of the camera unit 7. . Specifically, the cable space is formed between a back surface 9 g formed by the rear wall portion 9 f of the casing 9 and a holding surface 25 a that is a front surface of the holding piece portion 25. The cable 18 is held by the casing 9 and the holding piece 25 by passing through the cable holding space.

  The holding piece 25 has a locking projection 25b at the upper end. The locking projection 25b is a portion that forms a protruding portion from the holding surface 25a in the holding piece 25, and partially increases the plate thickness of the plate-like holding piece 25. The locking projection 25 b is formed in a straight line along the side of the upper end of the holding piece 25.

  The gap between the holding piece 25 and the casing 9 becomes relatively narrow at the portion of the locking protrusion 25b protruding from the holding surface 25a. The dimension of the gap between the locking projection 25 b and the back surface 9 g of the casing 9 is set smaller than the diameter of the cable 18. Further, the dimension of the gap between the portion other than the locking projection 25 b of the holding piece 25 and the back surface 9 g is set to be larger than the diameter of the cable 18. A space 25c between the locking projection 25b and the back surface 9g of the casing 9 is used to put the cable 18 in and out of the cable holding space.

  Specifically, the cable 18 is pushed into the cable holding space from the space 25c side. When the cable 18 is pressed into a space 25c having a gap smaller than the diameter of the cable 18, the holding piece 25 is elastically deformed so that the size of the gap in the space 25c is widened (shown by a two-dot chain line in FIG. 5). (See holding piece 25). Here, the elastic deformation of the holding piece portion 25 is a bending to the rear side starting from a connecting portion of the holding piece portion 25 with the base portion 21. Such elastic deformation of the holding piece 25 allows the cable 18 to enter from the space 25c side into the cable holding space.

  In order to promote elastic deformation of the holding piece portion 25 due to the pressing of the cable 18 against the space 25c, a chamfer is formed at a corner (on the upper end) of the holding piece portion 25 on the side facing the back surface 9g of the casing 9. A portion 25d is formed (see FIG. 5). The chamfered portion 25d is a portion that forms a slope that gradually narrows the size of the gap of the space 25c from the upper side to the lower side.

  Thus, the attachment part 10 constituted by the fixing part 20 having the holding piece part 25 is for holding the cable 18 of the camera unit 7 between the casing 9 which is a casing member constituting the camera unit 7. As a cable holding piece that forms a space, a holding piece portion 25 formed in the fixed component 20 is provided. In addition, as a method of positioning the cable 18 in the cable holding space, as described above, the cable holding space is not provided via the space 25c between the locking projection 25b of the holding piece 25 and the back surface 9g of the casing 9. Alternatively, the cable 18 may be inserted directly into a portion where the gap between the holding piece 25 and the casing 9 is larger than the diameter of the cable 18. Therefore, the holding piece 25 may not have the locking protrusion 25b.

  A second embodiment of the present invention will be described with reference to FIGS. In addition, about the part which is common in 1st embodiment of this invention, description is abbreviate | omitted using the same code | symbol. In the present embodiment, the fixing component 30 constituting the mounting portion 10 is different mainly in the shape of the pressing piece portion 24 in comparison with the fixing component 20 of the first embodiment.

  As shown in FIGS. 14 to 17, the fixed component 30 of the present embodiment includes a pressing piece portion 34 that extends in the front-rear direction as a portion for pressing the front portion 12 from the upper surface 12 a side. In the fixed component 30, the locking piece portion 22 provided at the front end portion of the base portion 21 has an extending portion 22 c that protrudes in the left-right direction with respect to the width of the base portion 21. For this reason, in the fixed component 30 of this embodiment, the width of the front locking piece 22 is larger than that of the fixed component 20 of the first embodiment.

  The pressing piece portion 34 has an elongated rectangular parallelepiped shape that extends from the extending portion 22 c substantially parallel to the base portion 21. In other words, the pressing piece portion 34 is a protruding piece shape obtained by forming a notch portion 34b from the rear side toward the front side in an integral substantially rectangular plate-like portion including the base portion 21 and the pressing piece portion 34. Have Therefore, the pressing piece portion 34 is formed to have a substantially L shape together with the front locking piece portion 22 in a side view of the fixed component 30.

  The pressing piece portion 34 presses the front portion 12 with the lower surface facing the upper surface 12a of the front portion 12 as a pressing surface 34a. That is, the pressing piece portion 34 presses the front portion 12 in a state where the pressing surface 34 a is in contact with the upper surface 12 a of the front portion 12.

  The pressing piece portion 34 presses the front portion 12 by its elasticity. The front portion 12 pressed by the pressing piece portion 34 is locked by the locking claw 23 of the locking piece portion 22. That is, the front portion 12 pressed by the pressing piece portion 34 is sandwiched between the pressing surface 34 a of the pressing piece portion 34 and the locking surface 23 a of the locking claw 23.

  Therefore, the dimension between the pressing surface 34a of the pressing piece portion 34 and the locking surface 23a of the locking claw 23 (see FIG. 15, reference numeral D3) is the thickness of the front portion 12 in the fixed component 30 in the natural state. Smaller than dimensions. As a result, the pressing piece 34 is pushed up by the front portion 12 fitting into the frame holding space and elastically deformed, and the front portion 12 held in the frame holding space is connected to the locking claw 23. Press between.

  Thus, the mounting part 10 constituted by the fixing part 30 having the pressing piece part 34 is elastically attached to the side of the locking claw 23 with the frame 4 fitted between the pair of locking piece parts 22. As a pressing piece that presses and holds the frame 4 between the locking claws 23, a pair of pressing piece portions 34 formed in the fixed component 30 is provided.

  A third embodiment of the present invention will be described with reference to FIGS. In addition, about the part which is common in 1st embodiment of this invention, description is abbreviate | omitted using the same code | symbol. In the present embodiment, the fixing component 40 constituting the mounting portion 10 is used to turn on / off the switch of the camera unit 7 by fixing / removing the camera unit 7 with respect to the frame 4.

  As shown in FIGS. 18 and 19, the fixed component 40 of the present embodiment functions as a switch member that energizes the camera unit 7 in relation to the frame 4 when the camera unit 7 is fixed to 4. . That is, when the camera unit 7 is fixed to the frame 4, the fixed component 40 comes into contact with a predetermined place in the frame 4, and the camera unit 7 fixed to the frame 4 is energized.

  The fixed component 40 has an electrode wiring portion 41. The electrode wiring portion 41 is provided in a state of being embedded in the base portion 21 in the fixed component 40. The fixed component 40 includes a pair of electrode wiring portions 41 that are disposed substantially parallel to each other.

  On the other hand, in the frame 4, a wiring pattern 42 made of a conductor is provided on the front portion 12. The wiring pattern 42 is provided in the front portion 12 in a state of being fitted into a recess 12b formed on the upper surface 12a, and is exposed to the upper surface 12a of the front portion 12.

  The frame 4 provided with the wiring pattern 42 is made of a conductive material such as metal. Thereby, an energization path including the electrode wiring portion 41 and the wiring pattern 42 inside the fixed component 40 is secured.

  With such a configuration, as the camera unit 7 is fixed to the frame 4 from the state of the camera unit 7 alone (see FIG. 19), the base portion 21 of the fixing component 40 comes into contact with the upper surface 12a of the front portion 12, The electrode wiring part 41 contacts the wiring pattern 42 (see FIG. 18). Thereby, the energization state about the camera unit 7 is obtained, and the switch is turned on.

  As an energization path in the present embodiment, the other electrode wiring portion 41 included in the fixed component 40 passes from the one electrode wiring portion 41 included in the fixed component 40 through the front portion 12 of the frame 4 via the wiring pattern 42. To the outside of the fixed component 40 is configured (see arrow G in FIG. 18).

  Thus, the mounting portion 10 constituted by the fixed component 40 is a wiring provided on the frame 4 as an energization function unit that brings the camera unit 7 into an energized state when the camera unit 7 is mounted on the frame 4. An electrode wiring portion 41 corresponding to the pattern 42 is provided. Note that the electrode wiring portion 41 included in the fixed component 40 may be formed by, for example, the fixed component 40 being partially formed of a conductive resin material. In other words, the electrode wiring portion 41 included in the fixed component 40 may be any one that can form the current-carrying path of the camera unit 7 together with the conductive material that forms the wiring pattern 42 and the frame 4.

  According to the configuration of the present embodiment, the camera unit 7 can be firmly fixed to the frame 4 without looseness by the fixing component 40 having the locking piece portion 22, the pressing piece portion 24, and the like. By being fixed to, an energized state can be obtained reliably.

  If there is a backlash in the fixed portion of the camera unit 7 with respect to the frame 4, the state of contact between the electrode wiring portion 41 and the wiring pattern 42 becomes unstable, and a state in which the electrode wiring portion 41 and the wiring pattern 42 are not conductive occurs. In this regard, according to the configuration of the present embodiment, the camera unit 7 is fixed to the frame 4 without rattling by the mounting portion 10 configured by the fixing component 40, so that the camera unit 7 is fixed to the frame 4. A stable energized state can be obtained.

  Further, according to the configuration of the present embodiment, the camera unit 7 cannot be energized without the frame 4 made of a conductive material. For this reason, the configuration of the present embodiment is a measure for preventing the camera unit 7 from being used for purposes other than the usage in a state where the camera unit 7 is fixed to the frame 4.

  A fourth embodiment of the present invention will be described with reference to FIGS. In addition, about the part which is common in 1st embodiment of this invention, description is abbreviate | omitted using the same code | symbol. In the present embodiment, the fixing component 50 constituting the mounting portion 10 differs mainly in the function of the pressing piece 24 in comparison with the fixing component 20 of the first embodiment.

  As shown in FIGS. 20 and 21, the fixing component 50 of the present embodiment uses a pressing piece portion 54 that presses the front portion 12 from the upper surface 12 a side, so that the camera unit 7 is fixed to the frame 4. The unit 7 is energized. Further, the fixed component 50 causes the camera unit 7 to be in a non-energized state by the pressing piece portion 54 when the camera unit 7 is detached from the frame 4. That is, in the mounting portion 10 of the present embodiment, the pressing piece portion 54 of the fixed component 50 is used, and the camera unit 7 is switched on / off by fixing / removing the camera unit 7 with respect to the frame 4.

  Energization / non-energization of the camera unit 7 is switched by contact / non-contact of the conductor 62 with respect to the substrate 61 of the camera unit 7. Here, the board | substrate 61 is a flexible printed circuit board etc., for example. The conductor 62 is, for example, a transparent conductive film.

  The substrate 61 is provided in a fixed state in the casing 9 of the camera unit 7. The conductor 62 is provided so as to be movable relative to the substrate 61 so that a contact state and a non-contact state with respect to the substrate 61 are switched.

  In the present embodiment, the conductor 62 is disposed on the lower side of the substrate 61 and provided so as to be movable in the vertical direction, so that the conductor 62 can be moved toward and away from the substrate 61. The conductor 62 is located away from the substrate 61 in a natural state where it is not subjected to the action of an external force (see FIG. 21). That is, the camera unit 7 is in a non-energized state when the conductor 62 is not subjected to an external force.

  The pressing piece 54 pushes up the conductor 62 and contacts the substrate 61 when the camera unit 7 is fixed to the frame 4 by the mounting portion 10 constituted by the fixing component 50. As a result, the camera unit 7 is energized. The pressing piece portion 54 has a push-up portion 54 b as a portion for pushing up the conductor 62 when the camera unit 7 is fixed to the frame 4.

  Specifically, the pressing piece portion 54 has a mountain shape with the portion of the push-up portion 54b as a vertex when viewed from the front as shown in FIG. The pressing piece portion 54 presses the front portion 12 with the lower surface facing the upper surface 12a of the front portion 12 as a pressing surface 54a. That is, the pressing piece portion 54 presses the front portion 12 in a state where the pressing surface 54 a is in contact with the upper surface 12 a of the front portion 12. The pressing surface 54 a is formed at the distal end portion of the pressing piece portion 54.

  The pressing piece portion 54 presses the front portion 12 by its elasticity. The front portion 12 pressed by the pressing piece portion 54 is locked by the locking claw 23 of the locking piece portion 22. That is, the front portion 12 pressed by the pressing piece portion 54 is sandwiched between the pressing surface 54 a of the pressing piece portion 54 and the locking surface 23 a of the locking claw 23.

  Therefore, the dimension between the pressing surface 54a of the pressing piece portion 54 and the locking surface 23a of the locking claw 23 is smaller than the thickness of the front portion 12 in the fixed part 50 in the natural state. As a result, the pressing piece 54 is pushed up by the front portion 12 being fitted into the frame holding space and elastically deformed, and the front portion 12 held in the frame holding space is connected to the locking claw 23. Press between.

  Then, from the state of the camera unit 7 alone (see FIG. 21), the pressing piece portion 54 is elastically deformed as the camera unit 7 is fixed to the frame 4. The pressing piece portion 54 is elastically deformed so that the portion of the push-up portion 54b is displaced upward, and pushes up the conductor 62. Thereby, the conductor 62 contacts the board | substrate 61, the board | substrate 61 and the conductor 62 are electrically connected, and it will be in an energized state (refer FIG. 20). That is, when the conductor 62 contacts the substrate 61, a signal in the substrate 61 is transmitted, and the switch of the camera unit 7 is turned on.

  The push-up portion 54 b of the pressing piece portion 54 pushes up the conductor 62 via the elastic body 63. The conductor 62 is attached to the upper end portion of the elastic body 63. The elastic body 63 absorbs the force that further pushes up the conductor 62 in contact with the substrate 61.

  As described above, the mounting portion 10 constituted by the fixed component 50 having the pressing piece portion 54 is in a state where the camera unit 7 is attached to the frame 4, thereby providing an energization function unit that brings the camera unit 7 into an energized state. It has a push-up portion 54b. The pressing piece 54 may have any shape that can mechanically and automatically put the camera unit 7 into an energized state or a non-energized state by elastic deformation accompanying attachment / detachment of the camera unit 7 to / from the frame 4.

  According to the configuration of the present embodiment, switching between energization / non-energization of the camera unit 7 when the camera unit 7 is attached to and detached from the frame 4 is not affected by the material constituting the frame 4. In addition, since it is not necessary to provide a wiring pattern or the like with a conductor on the frame 4 as in the third embodiment, the structure is simple.

  In the embodiment described above, the mounting portion 10 constituted by the fixing component 20 or the like fixes the camera unit 7 to the frame 4 at the left and right ends of the front portion 12 of the frame 4 (see FIG. 3). The number, position, etc. of 10 are not limited.

  As an example of a preferable arrangement of the attachment portion 10, for example, a configuration in which the attachment portion 10 is provided at the left and right center portion of the front portion 12 of the frame 4 as illustrated in FIG. In other words, in this configuration, the attachment portion 10 fixes the camera unit 7 to the frame 4 at the left and right center portion of the front portion 12.

  Further, in the above-described embodiment, the attachment portion 10 for removably fixing the camera unit 7 to the frame 4 is configured by the fixing component 20 that is a component separate from the casing 9 of the camera unit 7. .
