[0040] An example of an embodiment of a camera according to the technology of the present invention will be described with reference to the drawings.

[0041] In the following description, for the sake of convenience, three arrows, X, Y, and Z, are used to represent the front-to-back direction (also called the depth direction), width direction, and height direction of the camera 10. First, the height direction is represented by arrow Y, and the direction of arrow Y of the portion indicated by arrow Y is set as the upper direction of the camera 10, and the opposite direction is set as the lower direction. The width direction is represented by arrow X that is orthogonal to arrow Y, and the direction indicated by arrow X is set as the right direction of the camera 10, and the opposite direction is set as the left direction. Regarding the front-to-back direction, the direction orthogonal to arrow Y and arrow X is represented by arrow Z, and the direction indicated by arrow Z is set as the front direction of the camera 10, and the opposite direction is set as the rear direction. That is, in the camera 10, along the optical axis K (reference Figure 3 ) The direction toward the subject is the front direction. In addition, the meaning of the representation of the use side such as the upper side, the lower side, the left side, the right side, the front side and the rear side is the same as the representation of the use direction.

[0042] As an example, Figure 1 As shown, the camera 10 is a camera device for photographing a subject. In the camera 10, for example, the subject is photographed by the user pressing a shutter button. In the camera 10, a still image or a moving image including an image of the subject can be obtained. The size of the camera 10 is smaller than that of a general digital camera or instant camera (for example, the size that can be accommodated in the palm of an adult), and the user can operate it easily. The camera 10 is an example of a "camera" involved in the technology of the present invention.

[0043] The camera 10 includes a housing 12. The housing 12 contains an image pickup element 30 (see FIG. Figure 8 ) and electronic components for realizing the camera function of the camera 10. The housing 12 is a rounded pattern as a whole, and the details will be described later. That is, the outer peripheral surface of the housing 12 is mainly composed of a curved surface, and the appearance is roughly oval. The housing 12 is provided with an opening 16. The opening 16 allows the subject light to be incident on the photographic lens 20. Figure 1 In the example shown, the opening 16 exposes the lens unit 18 to the outside. The lens unit 18 is configured to include a photographic lens 20 and a holding frame 18A that holds the photographic lens 20. Here, exposing the lens unit 18 includes a method of directly exposing it and a method of covering it with a covering member or the like within a range that does not affect the photographing of the subject.

[0044] Furthermore, when the side of the housing 12 provided with the opening 16 is regarded as the front side 12A of the housing 12, a speaker section 24 and a flash section 26 are provided on the front side 12A. The speaker section 24 outputs various operation sounds (for example, electronic sounds simulating the sound of pressing a shutter) from a sound source (not shown) provided inside the housing 12. Figure 1 In the example shown, sound is output through the three through holes 24A. In addition, in the flash unit 26, light is emitted toward the subject from a light source (not shown) provided inside the housing 12. Figure 1 In the example shown, the light source is covered by a cover member 26A provided on the housing 12 .

[0045] An indicator 14 is provided on the upper part of the housing 12. The housing of the indicator 14 is formed of a translucent material, and light from a light source 14A provided inside the indicator 14 is emitted to the outside. The indicator 14 can notify the camera 10 of information by emitting light. For example, the indicator 14 can emit light according to the operating state of the camera 10. The indicator 14 is an example of a "light emitting unit" involved in the technology of the present invention.

[0046] For example, when the camera 10 has a communication function with the outside, the indicator 14 emits light at a preset light-emitting interval and light-emitting color while the camera 10 is communicating with the outside. Figure 1 The illustrated example shows an example in which the smartphone 100 performs wireless communication with the camera 10. In this case, the indicator 14 performs a light-emitting operation indicating that the camera 10 is communicating with the outside.

[0047] As a result of the wireless communication, data representing the captured image IM acquired by the camera 10 is transmitted to the smartphone 100 , and the user can check the captured image IM using the smartphone 100 .

[0048] In addition, here, as an example of communication between the camera 10 and the outside, the data representing the captured image IM is sent to the smartphone 100, but this is only an example, and the data representing the captured image IM may be sent to an external printing device. In addition, for example, software (for example, a control program for the camera 10) may be downloaded to the camera 10.

[0049] Here, the information of the camera 10 notified by the indicator 14 is the state of communication between the camera 10 and the outside, but this is only an example. For example, the indicator 14 may also notify that the camera 10 is malfunctioning or that software is being updated in the camera 10 as the operating state of the camera 10.

[0050] And, in Figure 1 In the example shown, the indicator 14 is a portion protruding upward from the housing 12. When the housing 12 is viewed from the front, the indicator 14 has a trapezoidal shape.

[0051] Furthermore, a through hole may be formed at a position corresponding to the light source in the housing of the indicator 14. Thus, the light emitted from the light source is easily emitted to the outside through the through hole. As a result, the light emission of the indicator 14 is easily visually recognized from the outside.

[0052] Furthermore, a power switch 15 is provided on the upper surface 14B of the indicator 14. The power switch 15 is provided on the upper surface 14B of the indicator 14 along the left-right direction ( Figure 1 The power switch 15 can be set in the X direction as shown. The power of the camera 10 can be turned on by pressing the power switch 15 several times (for example, three times). And the power of the camera 10 can be turned off by pressing the power switch 15 for several seconds (for example, three seconds).

[0053] Furthermore, a lower surface 12C is formed at the lower portion of the housing 12. At least a portion of the area including the center of the lower surface 12C is formed by a plane. Thus, the camera 10 can be placed on a desk or the like. Here, the plane includes a completely flat surface and a surface having a flatness that allows the housing 12 to be placed.

[0054] And, as an example, Figure 2 As shown in FIG. 1 , when the side opposite to the front face 12A in the housing 12 is the back face 12B (i.e., the side opposite to the front face 12A in the optical axis direction of the photographic lens 20 is the back face 12B), a shutter button 28 is provided on the back face 12B. The shutter button 28 is provided so as to be pressable toward the front face 12A side. As described above, when the user presses the shutter button 28, the camera 10 captures the subject.

[0055] In addition, in general digital cameras, a display unit (e.g., a liquid crystal display, etc.) for confirming the subject image is often mounted on the back. On the other hand, in the present embodiment, a display unit for confirming the subject image is not provided on the back 12B of the camera 10. In addition, in the camera 10, a display unit for purposes other than confirming the subject image (e.g., a display unit indicating the remaining battery level) may be provided on the back 12B.

[0056] Furthermore, a receiving unit 29 is provided on the back side 12B of the housing 12. The receiving unit 29 is a terminal for receiving an electrical connection with an external device, and is, for example, a USB (Universal Serial Bus) terminal. The battery of the camera 10 is charged via the receiving unit 29, or wired communication between the camera 10 and an external device is performed.

[0057] Here, as described above, the camera 10 is a smaller camera than a general digital camera. Therefore, in order to further improve the convenience of the camera 10, as an example, Figure 2 As shown, the camera system 1 according to the present embodiment includes a camera 10 and an accessory 50. The camera system 1 is an example of a “camera system” according to the technique of the present invention.

[0058] The accessory 50 is a part that is attached to the camera 10 and can be mounted on the camera 10. Figure 2 In the example shown, the accessory 50 is connected via the camera 10 and the cord S. Specifically, one end of the cord S is attached to the back surface 12B of the camera 10, and the other end is attached to the accessory 50. The accessory 50 is an example of an "accessory" involved in the technology of the present invention.

[0059] The accessory 50 includes a frame portion 52, a mounting portion 54, and a pair of cord mounting portions 56A and 56B. The frame portion 52 is a frame-shaped portion that functions as a frame that defines a field of view when the accessory 50 functions as a viewfinder. The mounting portion 54 is a portion for mounting the accessory 50 on the housing 12 of the camera 10. Figure 2 In the illustrated example, the frame portion 52 is an example in which the frame portion 52 is an annular frame.

[0060] The pair of rope mounting portions 56A and 56B are used to mount the rope S on the accessory 50. Figure 2 In the illustrated example, the other end of the cord S is attached to a cord attachment portion 56A provided on a side surface of the attachment 50 .

[0061] The accessory 50 functions as a grip for carrying the camera 10. That is, the camera 10 can be easily carried by hooking a finger inside the frame of the frame 52 of the accessory 50 or by hooking the frame of the frame 52 on a hook.

[0062] As an example, Figure 3 As shown, the frame portion 52 includes a first protrusion 52A and a second protrusion 52B on the upper surface side. When the accessory 50 functions as a mounting platform for the camera 10, the first protrusion 52A and the second protrusion 52B abut against the lower surface 12C of the camera 10, and the details will be described later. The first protrusion 52A and the second protrusion 52B are examples of the "plurality of supporting protrusions" involved in the technology of the present invention.

[0063] Furthermore, the frame portion 52 includes a first leg portion 52C and a second leg portion 52D on the lower surface side. When the attachment 50 functions as a mounting table, the first leg portion 52C and the second leg portion 52D come into contact with the installation surface of the attachment 50 .

[0064] The mounting portion 54 includes a through hole 54A, a first mounting guide portion 54B, and a second mounting guide portion 54C. The through hole 54A penetrates the frame of the frame portion 52 and the mounting portion 54. That is, when the accessory 50 is viewed from the mounting portion 54 side, the inside of the frame portion 52 can be visually recognized. The mounting portion 54 is an example of a "mounting portion" involved in the technology of the present invention, the frame portion 52 is an example of a "frame" involved in the technology of the present invention, and the through hole 54A is an example of a "through hole" involved in the technology of the present invention.

[0065] The first mounting guide 54B and the second mounting guide 54C are wall-shaped portions protruding from the ends of the mounting portion 54. When the accessory 50 is mounted on the indicator 14, the first mounting guide 54B and the second mounting guide 54C guide the mounting. In addition, the first mounting guide 54B and the second mounting guide 54C hold the indicator 14 from the side when the accessory 50 is mounted on the indicator 14.

[0066] exist Figure 3 In the example shown, a pair of the first mounting guide 54B and the second mounting guide 54C is provided at the end of the mounting portion 54. The first mounting guide 54B and the second mounting guide 54C are formed into a circular arc wall shape. The shape of the inner wall surface of the first mounting guide 54B and the second mounting guide 54C corresponds to the side shape of the indicator 14.

[0067] As an example, Figure 4 As shown, the accessory 50 is mounted on the camera 10. The accessory 50 is mounted on the indicator 14 of the camera 10 via the mounting portion 54. Specifically, the accessory 50 is mounted on the indicator 14 from above the indicator 14. In this case, the first mounting guide portion 54B and the second mounting guide portion 54C of the mounting portion 54 hold the side surface of the indicator 14. Thus, the accessory 50 is mounted on the indicator 14.

[0068] If the indicator 14 emits light in this state, the light emitted from the indicator 14, which is emitted upward, passes through the through hole 54A of the mounting portion 54. Then, part of the light passing through the through hole 54A illuminates the inside of the frame 52 of the accessory 50. For example, the inner area U of the frame 52 is illuminated by the light emitted from the indicator 14. In this way, the accessory 50 can illuminate the light emitted from the indicator 14 to the inside of the frame 52.

[0069] As an example, Figure 5 As shown, the light emitted from the indicator 14 is irradiated to the inside of the frame 52 of the accessory 50, whereby the light is reflected inside the frame 52. A part of the reflected light travels in a direction toward the user's eyes E. Thus, the user can visually recognize the light emitted from the indicator 14.

[0070] Next, an example of how the camera 10 according to the present embodiment is used will be described.

[0071] As an example, Figure 6 As shown, the user holds the camera 10 by pinching the housing 12 from the front and back with fingers. Specifically, the user brings the index finger F1 and the middle finger F2 into contact from the front 12A side of the housing 12 toward the back 12B side, and further brings the thumb F3 into contact from the back 12B side toward the front 12A side. On the front 12A of the housing 12, the opening 16 is pinched by the index finger F1 and the middle finger F2. In particular, the middle finger F2 is brought into contact with the front 12A in a manner that supports the opening 16 from below. On the other hand, on the back 12B, the user brings the thumb F3 into contact with the shutter button 28.

[0072] In addition, as another way of holding the camera 10, the middle finger F2 may be brought into contact with the right side of the opening 16, and the index finger F1 may be brought into contact with the left side of the opening 16. Furthermore, the user may hold the camera 10 by pinching the housing 12 from above and below with fingers. Of course, the camera 10 may be held or operated by the user's two hands.

[0073] The accessory 50 has a function as a viewfinder when attached to the camera 10. For example, when the user looks through the viewfinder, the frame 52 of the accessory 50 becomes a reference for confirming the shooting range. Here, the frame 52 of the accessory 50 is not provided with an optical element such as a lens, so the frame 52 functions as a simple viewfinder (so-called sports viewfinder).

[0074] The frame 52 functions as a simple viewfinder, such as Figure 6 As shown, when used as a viewfinder, the user visually recognizes the subject through the frame that serves as a reference for confirming the photographic range, and has a function of confirming the photographic range by obtaining the direction of the camera 10 toward the subject and the reflection range of the subject's periphery.

[0075] Furthermore, the accessory 50 can function not only as a simple finder but also as a finder having an optical system such as a real image type or virtual image type finder. In this case, the frame portion 52 of the accessory 50 is provided with various optical elements.

[0076] Furthermore, when the accessory 50 functions as a viewfinder, the indicator 14 is arranged at a position that can be visually recognized by the user while the user is observing the viewfinder. The position at which the user can visually recognize the indicator 14 is set so that the distance L between the user's eye E and the accessory 50 serving as the viewfinder becomes an appropriate position. The field of view ER within the frame 52 when observing the viewfinder at this position corresponds to the imaging range IR of the camera 10. That is, the field of view ER is consistent with the imaging range IR. In addition, consistency includes a situation of complete consistency, and includes an error of a degree allowed in the technical field to which the technology of the present invention belongs. In this way, when the user uses the viewfinder, the exposed part of the indicator 14 is visually recognized by the user, and the indicator 14 becomes a reference indicating that the field of view of the subject observed from the viewfinder corresponds to the imaging range.

[0077] Then, after checking the imaging range by looking at the viewfinder, the user presses the shutter button 28 (see FIG. Figure 6 Thus, photographing is performed by the camera 10.

[0078] And, as an example, Figure 7 and Figure 8 As shown, the accessory 50 also functions as a mounting table on which the camera 10 can be mounted. When the accessory 50 is set on the mounting surface G, the camera 10 is mounted on the upper side of the frame portion 52 of the accessory 50. For example, the mounting portion 54 side of the accessory 50 is located on the front side 12A of the camera 10, and the frame portion 52 of the accessory 50 is located on the back side 12B of the camera 10. In addition, the size of the annular frame of the frame portion 52 is capable of holding the periphery of the lower surface 12C of the housing 12 of the camera 10. In addition, the first protrusion 52A and the second protrusion 52B provided on the frame portion 52 can abut against the lower portion of the camera 10. In other words, the first protrusion 52A and the second protrusion 52B serve as support points for supporting the camera. Thus, it is possible to prevent the camera 10 from being detached from the mounting table and being supported in an unstable state.

[0079] Furthermore, when the camera 10 is placed on the accessory 50 that functions as a mounting table, the optical axis K is directed upward relative to the horizontal direction. That is, the camera 10 is placed on the mounting table to give an elevation angle. Here, the height of the frame 52 from the setting surface G varies along the circumferential direction of the frame 52. Specifically, the height of the frame 52 is higher on the mounting portion 54 side. That is, when the accessory 50 is viewed from the side, the height of the mounting portion 54 is higher than the height of the frame 52. Therefore, when the camera 10 is placed on the accessory 50 that functions as a mounting table, the optical axis K of the camera 10 is tilted in a direction away from the setting surface G on the subject side of the optical axis K. In this way, the accessory 50 that functions as a mounting table can mount the camera 10 in a posture in which the optical axis K of the camera 10 is tilted relative to the horizontal direction.

[0080] As an example, Fig. 9 As shown, the accessory 50 that functions as a mounting table has a shape that can adjust the tilt angle of the optical axis K relative to the horizontal direction. That is, the tilt angle is adjusted by the user rotating the camera 10 in a direction in which the elevation angle relative to the accessory 50 is changed. Specifically, when the accessory 50 is viewed from the side, a continuous inclined surface is formed from the mounting portion 54 to the frame portion 52. And, as described above, the height of the mounting portion 54 is higher than the frame portion 52. Therefore, by changing the inclination of the camera 10 along the inclined surface, the optical axis K of the camera 10 can be adjusted relative to the horizontal direction.

[0081] exist Fig. 9 In the example shown, the user tilts the camera 10 upward. That is, the camera 10 moves in the direction in which the optical axis K1 of the camera 10 is adjusted to the optical axis K2. In addition, the tilt angle θ1 relative to the line HZ along the horizontal direction before adjustment is changed to the tilt angle θ2 after adjustment. In this way, the optical axis K of the camera 10 can be adjusted relative to the horizontal direction.

[0082] As described above, the camera system 1 according to the present embodiment includes: a camera 10 having an indicator 14; and an accessory 50 that can be mounted on the camera 10. When the accessory 50 is mounted on the camera 10, it functions as a viewfinder for confirming the photographing range of the camera 10. Then, the light emitted from the indicator 14 can be irradiated to the inside of the frame of the viewfinder. Thus, compared with an accessory having a function as a conventionally known viewfinder, the inside of the frame of the viewfinder can be illuminated by the light from the indicator 14, so that the user can easily visually recognize the light emitted by the indicator 14.

[0083] Furthermore, for example, compared with a configuration in which the camera and the viewfinder are always integrated, since the accessory 50 attached to the camera 10 functions as a viewfinder, the camera 10 can be made more compact.

[0084] In the conventionally known auxiliary viewfinder, a light emitting unit is provided outside the frame of the viewfinder. Therefore, there is a disadvantage that even in a hot summer day when the surroundings are bright, it is difficult to visually recognize even if the light emission is increased, and it is also difficult to confirm the light emission in a usage mode where the eyes are close to the eyepiece unit or in a case where a user of glasses is used. Therefore, due to the above configuration, the light emission is irradiated into the frame of the auxiliary viewfinder, so that the user can easily visually recognize the light emission by the light emitting unit.

[0085] Furthermore, in the camera system 1 according to the present embodiment, a through hole 54A is formed in the attachment 50 for the mounting portion 54 of the camera 10. Then, the light from the indicator 14 passes through the through hole 54A, so that the light from the indicator 14 can be irradiated to the inside of the frame 52. Thus, compared with the case where a light guide member is provided on the attachment 50, the user can easily visually recognize the light emitted by the indicator 14 with a simplified structure.

[0086] Furthermore, in the camera system 1 according to the present embodiment, the frame portion 52 in the accessory 50 serves as a reference for confirming the photographic range, and the accessory 50 functions as a simple viewfinder without a lens. Thus, since the viewfinder defines the field of view in a frame shape, the function as a viewfinder can be realized with a simple structure compared to a case where the viewfinder has an optical element such as a lens.

[0087] Furthermore, if an optical element is provided in the frame 52, the light from the indicator 14 is deflected or diffracted by the optical element, so that it is sometimes difficult for the user to visually recognize the light emitted by the indicator 14. In this configuration, since the accessory 50 functions as a simple viewfinder without a lens, the user can easily visually recognize the light from the indicator 14.

[0088] Furthermore, in the camera system 1 according to the present embodiment, in addition to the function as a viewfinder, the accessory 50 also functions as a grip for carrying the camera 10 or as a mounting table on which the camera 10 can be mounted. Thus, even when the accessory 50 is not mounted, other functions of the accessory 50 can be utilized, and thus the usability of the accessory 50 is improved compared to an accessory 50 having only a single function.

[0089] Furthermore, in the camera system 1 according to the present embodiment, the accessory 50 also functions as a mounting table on which the camera 10 can be mounted. Thus, the camera 10 can be stably mounted compared to a case where the camera 10 is directly mounted on the mounting surface G without the mounting table. This configuration is effective when the camera 10 is used as a fixed-point camera, for example.

[0090] Furthermore, in the camera system 1 according to the present embodiment, the accessory 50 functioning as a mounting platform can mount the camera 10 in a posture in which the optical axis K of the camera 10 is tilted relative to the horizontal direction. Thus, by tilting the optical axis K of the camera 10 relative to the horizontal direction, the imaging range of the camera 10 can be changed, and further, the tilted posture of the camera 10 can be stably maintained. For example, by mounting the camera 10 in a state in which the optical axis K of the camera 10 is tilted in a direction away from the installation surface G, the subject (for example, a person) requested by the user can be included more in the imaging range.

[0091] Furthermore, in the camera system 1 according to the present embodiment, the attachment 50 functioning as a mounting table has a shape capable of adjusting the tilt angle θ of the optical axis K relative to the horizontal direction. Thus, since the tilt angle of the camera 10 can be adjusted, it is possible to shoot at a tilt angle requested by the user.

[0092] Furthermore, in the camera system 1 according to the present embodiment, in the accessory 50 functioning as a mounting table, the tilt angle can be adjusted by making the height of the frame 52 from the installation surface G different in the circumferential direction of the frame 52. Thus, since the tilt angle of the camera 10 can be adjusted, it is possible to shoot at a tilt angle requested by the user.

[0093] Furthermore, in the camera system 1 according to the present embodiment, in the accessory 50, the frame portion 52 serves as a reference for confirming the photographing range, and the accessory 50, when used as a mounting platform, has a first protrusion 52A and a second protrusion 52B for supporting the camera 10. Furthermore, the first protrusion 52A and the second protrusion 52B are arranged on the frame portion 52. Thus, the first protrusion 52A and the second protrusion 52B abut against the lower portion of the camera 10 to support it, and thus the camera 10 mounted on the accessory 50 functioning as a mounting platform is stably supported.

[0094] Furthermore, in the camera system 1 according to the present embodiment, the camera 10 has a communication function, and when the camera 10 communicates with an external device, the indicator 14 emits light to notify the camera 10 that the communication is in progress. When the camera 10 is communicating with an external device, it may not be suitable for shooting. The user can recognize whether the camera 10 is in a state suitable for shooting by visually recognizing the inside of the frame 52 of the accessory 50 that functions as a viewfinder.

[0095] Furthermore, in the camera system 1 according to the present embodiment, when the user is viewing the viewfinder mounted on the camera 10, the indicator 14 is arranged at a position where the user can visually recognize the light emitted by the indicator 14. When the viewfinder is used, since the indicator 14 can be visually recognized by the user, it is possible to achieve shooting within the imaging range desired by the user. That is, when the viewfinder is used, the indicator 14 becomes a reference indicating that the field of view observed from the viewfinder corresponds to the imaging range, and it is possible to achieve shooting within the imaging range desired by the user.

[0096] (First Modification)

[0097] In the above embodiment, the light from the indicator 14 is irradiated to the inside of the frame 52 through the through hole 54A, but the technology of the present invention is not limited thereto. In the first modification, a part of the attachment 50 is formed of a light-transmitting material.

[0098] As an example, Fig.10 As shown, a light-transmitting portion 58 is formed in the mounting portion 54 of the attachment 50. The light-transmitting portion 58 transmits the light emitted from the indicator 14. The light-transmitting portion 58 is formed of a material transparent to visible light, that is, a light-transmitting material. For example, the light-transmitting material is acrylic resin.

[0099] exist Fig.10 In the example shown, the light-transmitting portion 58 is formed between the mounting portion 54 and the frame portion 52. The light emitted from the indicator 14 passes through the light-transmitting portion 58, and a portion of the light irradiates the inner side of the frame portion 52 of the accessory 50. For example, the inner area U of the frame portion 52 is irradiated by the light emitted from the indicator 14. In this way, the accessory 50 can irradiate the light emitted from the indicator 14 to the inner side of the frame portion 52.

[0100] As described above, in the first modification, a part of the accessory 50 is formed of a light-transmitting material, and the light from the indicator 14 can be irradiated to the inside of the frame 52. Thus, the inside of the viewfinder frame can be illuminated by the light from the indicator 14, so that the user can easily visually recognize the light emitted by the indicator 14.

[0101] Furthermore, in the first modification, light is scattered not only inside the frame 52 but also in the light-transmitting portion 58 , so that part of the accessory 50 itself also emits light, and thus the user can easily visually recognize the light emission of the indicator 14 .

[0102] In the first modification, a part of the attachment 50 is formed of a light-transmitting material, but the technology of the present invention is not limited thereto. For example, the entire attachment 50 may be formed of a light-transmitting material.

[0103] (Second Modification)

[0104] In the above embodiment, the light from the indicator 14 is irradiated to the inside of the frame 52 through the through hole 54A, but the technology of the present invention is not limited thereto. In the second modification, the attachment 50 is provided with a light guide member 60 .

[0105] As an example, Fig.11 As shown in FIG. 5 , the accessory 50 includes a light guide member 60 between the mounting portion 54 and the frame portion 52. The light guide member 60 is a member that guides the light from the indicator 14 to the inside of the frame portion 52 by allowing the light from the indicator 14 to propagate inside. Fig.11 In the example shown, a prism 61 is shown as the light guide member 60. The prism 61 is made of resin, and the light from the indicator 14 travels along the optical path R formed inside the prism 61. Specifically, the light emitted from the light source 14A of the indicator 14 is reflected by the first reflection surface 62, and further reflected by the second reflection surface 64. Then, the light reflected by the second reflection surface 64 is emitted toward the inside of the frame 52.

[0106] The light emitted from the indicator 14 passes through the light guide member 60, and a part of it illuminates the inside of the frame 52 of the accessory 50. For example, the inner area U of the frame 52 is illuminated by the light emitted from the indicator 14. In this way, the accessory 50 can illuminate the light emitted from the indicator 14 to the inside of the frame 52.

[0107] As described above, in the second modification, the light guide member 60 is provided in the accessory 50. The light from the indicator 14 can be irradiated to the inside of the frame 52 via the light guide member 60. Thus, the inside of the frame of the viewfinder can be illuminated by the light from the indicator 14, so that the user can easily visually recognize the light emission by the indicator 14.

[0108] Furthermore, in the second modification, since the light from the indicator 14 is irradiated to the inside of the frame 52 by the light guide member 60 , a large amount of light can be guided to the frame 52 , and the user can easily visually recognize the light emission.

[0109] In addition, in the second modification, the prism 61 is used as the light guide member 60, but the technology of the present invention is not limited to this. Fig.12 As shown, a fiber 66 is used as the light guide member 60. One end of the fiber 66 is provided at a position opposite to the light source 14A of the indicator 14, and the other end of the fiber 66 is provided inside the frame 52. The light from the indicator 14 propagates inside the fiber 66 and is emitted toward the inside of the frame 52.

[0110] (Other embodiments)

[0111] As described above, the power switch 15 is provided on the indicator 14 of the camera 10. Specifically, the power switch 15 is provided on the upper surface 14B of the indicator 14. The power switch 15 can emit light according to the operation state. The power switch 15 is an example of the "operating unit" involved in the technology of the present invention.

[0112] If the power switch 15 is operated by mistake by the user, the power of the camera 10 may be turned off without the user's intention, such as during use of the camera 10 or communication with the outside. Therefore, it is sometimes required to provide a switch cover to suppress mistaken operation of the power switch 15.

[0113] As a conventionally known technology related to a switch cover, there is a switch cover which, in a plan view, is composed of a quadrilateral box-shaped frame and a cover for opening and closing an opening defined by the frame. The switch cover is mounted on the camera in such a manner that the switch is housed inside the box-shaped frame. The opening is of a size that allows the user's finger to be inserted. When the switch cover is mounted on the camera, the opening is closed by the cover when the switch is not operated. Furthermore, when the user operates the switch, the cover is opened, and the user inserts a finger into the opening to press the switch. Thus, in a state where the cover of the opening is closed, the user's erroneous operation can be suppressed. However, in the case of this structure, it is necessary to provide an opening and closing mechanism (e.g., a hinge mechanism) for the cover on the switch cover. If the opening and closing mechanism for the cover is provided, the freedom of design such as the shape and size of the switch cover is sometimes limited. In particular, when the housing of the camera 10 involved in the present embodiment is small and the main body of the camera 10 has a characteristic design, it is sometimes difficult to make the design of the switch cover suitable for the design of the camera 10 if there are restrictions on the shape and size.

[0114] Furthermore, as a previously known technology related to other switch covers, there is a cover made of soft resin that covers the entire switch. In this case, when the user presses the switch, if an external force greater than a specified value is applied from the user's finger, the switch cover is elastically deformed, so that the switch is directly pressed through the cover. Therefore, under weak forces such as light contact, the switch cover will not deform or the deformation is small, so it is possible to suppress erroneous operations caused by the user. However, this switch cover that covers the entire switch has the following problems. That is, there is a switch in the camera that emits light according to the operating state. When a switch cover that covers the entire switch on a switch cover with a light-emitting function is used, in order to ensure the visual recognition of the light, the color of the switch cover needs to be formed of a light-transmitting material, resulting in color restrictions. Similar to the above-mentioned conventional technology, the color restriction becomes a restriction on the design freedom of the switch cover.

[0115] Therefore, in this embodiment, the accessory 50 is used as a switch cover. In other words, the accessory 50 also has a function as a switch cover. Fig.13As shown in FIG. 1 , the accessory 50 is set to a state where it is attached to the indicator 14 . In this state, a case where a user's finger F mistakenly approaches the power switch 15 from above the indicator 14 is considered.

[0116] In this case, as an example, Fig.14 As shown, the power switch 15 is provided in a state of protruding from one side of the camera 10 (here, the upper surface 14B of the indicator 14). In addition, the accessory 50 has a limiting portion 59. When the accessory 50 is mounted on the camera 10, the limiting portion 59 limits contact with the power switch 15. The limiting portion 59 is an example of a "limiting portion" involved in the technology of the present invention.

[0117] The limiting portion 59 is disposed at least partially around the power switch 15. Fig.14 In the example shown, the limiting portion 59 is provided as a peripheral wall 59A surrounding the power switch 15. The peripheral wall 59A is an example of a "peripheral wall" involved in the technology of the present invention. When the accessory 50 is mounted on the indicator 14, the height h1 of the limiting portion 59 from the upper surface 14B of the indicator 14 is longer than the protruding height h2 of the power switch 15. That is, the limiting portion 59 has a height higher than the protruding amount of the power switch 15. Thus, if the finger F attempts to approach the power switch 15, the finger F first contacts the upper portion of the limiting portion 59 and is prevented from contacting the power switch 15. As a result, it is possible to prevent the finger F or the like from accidentally contacting the power switch 15.

[0118] The restricting portion 59 has sufficient rigidity against the pressing force of the user, and the height h1 of the restricting portion 59 is maintained at a height that can suppress contact with the power switch 15 even when pressed by the finger F. That is, even when the restricting portion 59 is pressed by the finger F, the opening area 59B is separated from the power switch 15 by a predetermined distance or more.

[0119] As an example, Fig.15 As shown in FIG. 1 , when the power switch 15 is viewed from the top 59A1 of the head in the height direction of the limiting portion 59, an opening area 59B is formed in the limiting portion 59. The opening area 59B is formed to overlap at least a portion of the power switch 15. The opening area 59B transmits light emitted from the power switch 15. The top 59A1 is an example of the “top” of the head involved in the technology of the present invention, and the opening area 59B is an example of the “opening area” involved in the technology of the present invention.

[0120] As described above, the peripheral wall 59A surrounds the power switch 15. Fig.15 In the example shown, the opening region 59B is a single opening 59B1 partitioned by the peripheral wall 59A. The opening 59B1 is an example of the “opening” involved in the technique of the present invention.

[0121] Furthermore, the size of the opening area 59B is set to be able to suppress the finger F from entering the power switch 15. Here, the size of the user's finger F refers to the average value of the width of the index finger of an adult (here, it refers to the distance in the direction perpendicular to the long side direction of the finger when the finger is viewed from the back of the hand), and in particular, the average value of the width of the base of the nail of the index finger (the part of the nail closest to the first joint side). And the size that can suppress the entry of the finger F refers to a size below the average value.

[0122] Here, the opening 59B1 is formed into an elliptical shape in a plan view. The distance t in the short-diameter direction of the opening 59B1 is set to a distance that can suppress the finger F from contacting the power switch 15 and ensure the amount of light from the indicator 14. For example, the distance t is 10 mm or less.

[0123] In addition, here, the opening 59B1 is described as an elliptical form, but the technology of the present invention is not limited to this. The opening 59B1 may also be an oval. In addition, the opening 59B1 may also be a rectangle. In this case, the distance t is the distance in the short side direction of the rectangle.

[0124] Furthermore, the opening 59B1 is open to the outside. In other words, the inside of the opening 59B1 is not filled with resin, and a cover is not attached to the opening 59B1.

[0125] Furthermore, when the attachment 50 is attached to the indicator 14 , a member including a portion facing the opening region 59B is provided on an extension line L1 of a straight line extending from the power switch 15 toward the opening 59B1 in the height direction of the restricting portion 59 .

[0126] exist Fig.14 In the example shown, a frame portion 52 is provided above the restricting portion 59. As described above, as an example, the frame portion 52 is in an annular shape. The upper arc portion 52E of the annular frame portion 52 is provided at a position opposite to the opening 59B1. The frame portion 52 is in an annular shape with the direction along the straight line as the radial direction. The frame portion 52 is an example of a "component" involved in the technology of the present invention, and the upper arc portion 52E is an example of an "opposing portion" involved in the technology of the present invention.

[0127] The presence of the arc portion 52E makes it difficult for a finger F or the like to approach the restricting portion 59 from above. For example, consider a case where a finger F approaches the opening 59B1 from the front end of the finger F. In this case, the finger F interferes with the upper arc portion 52E of the circular ring of the frame portion 52 above the restricting portion 59 (see FIG. 5B ). Fig.14 ). Therefore, in the posture where the nail of the finger F is inserted into the opening 59B1, the finger F can be restricted from approaching the opening 59B1, and the finger F can be prevented from accidentally touching the power switch 15.

[0128] According to the accessory 50 involved in this embodiment, the power switch 15 is provided on the camera 10, and the accessory 50 is mounted on the camera 10. In addition, the accessory 50 is provided with a restricting portion 59. The restricting portion 59 has a height h1 higher than the protrusion amount h2 of the power switch 15. In addition, the restricting portion 59 is provided with an opening 59B1 that overlaps with a part of the power switch 15 when viewed from above. The size of the opening 59B1 is set to allow the light of the power switch 15 to pass through and to prevent the user's finger from entering.

[0129] Thus, when the accessory 50 is mounted on the indicator 14, even if the user's finger F attempts to approach the power switch 15 by mistake, it will first contact the limiting portion 59, thereby preventing contact with the power switch 15. That is, there is no need to provide a cover at the opening 59B1, thereby increasing the freedom of design (e.g., shape and size) of the accessory 50. For example, it is possible to design the accessory 50 to match the camera 10. Furthermore, since the light from the power switch 15 is irradiated to the outside through the opening 59B1, it is possible to achieve the freedom of material selection of the limiting portion 59. For example, a material other than a transparent material can be used.

[0130] Furthermore, even when the limiting portion 59 is pressed by a finger F, the position of the top portion 59A1 is separated from the power switch 15 by a predetermined distance or more. Thus, it is possible to suppress the finger F or the like from accidentally touching the power switch 15. For example, sometimes the power switch 15 is pressed through the cover by the pressing force even in the case of unintentional operation. In this structure, even when pressed by a finger F, the limiting portion 59 can ensure a sufficient distance between the power switch 15 and the top portion 59A1 of the limiting portion 59, so that it is possible to further suppress the finger F from accidentally touching.

[0131] Furthermore, according to the accessory 50 involved in this embodiment, the limiting portion 59 is a peripheral wall 59A. The peripheral wall 59A defines the opening 59B1. Thus, the peripheral wall 59A can disperse and support the force received from the finger F approaching the power switch 15, and it is also possible to suppress the approach from multiple directions such as front, back, left, and right. As a result, it is possible to suppress the finger F from approaching the power switch 15.

[0132] Furthermore, according to the accessory 50 of the present embodiment, the opening 59B1 is elliptical, and the distance t in the minor diameter direction is less than 10 mm. When the finger F contacts the power switch 15, it is difficult for a human finger to contact the power switch 15 through a gap of 10 mm, so the finger F can be prevented from accidentally contacting the power switch 15.

[0133] Furthermore, according to the accessory 50 of the present embodiment, in the state where the accessory 50 is mounted, the frame portion 52 is provided above the restriction portion 59. The arc portion 52E on the upper side of the frame portion 52 is provided at a position facing the opening area 59B. Thus, the posture of the finger F such as inserting the nail of the finger F into the opening area 59B can be restricted, and the finger F can be prevented from accidentally touching the power switch 15.

[0134] Furthermore, according to the accessory 50 of this embodiment, the frame portion 52 is an annular member including the upper arc portion 52E and the extension line L1 is set in the radial direction. Therefore, the structure of the accessory 50 can be simplified compared with the case where a member for restricting the posture of the finger F is provided at a position opposite to the opening area 59B.

[0135] In addition, in the above-mentioned embodiment, the example of the form in which the opening 59B1 is formed as the opening area 59B is described, but the technology of the present invention is not limited to this. In this modification, as the opening area 59B, a plurality of openings 59B2 are formed. The plurality of openings 59B2 is an example of the "plurality of openings" involved in the technology of the present invention.

[0136] As an example, Fig.16 As shown in FIG. 1 , a ceiling portion 59A2 is formed at the top portion 59A1 of the restricting portion 59. The ceiling portion 59A2 covers the power switch 15. A plurality of openings 59B2 are formed in the ceiling portion 59A2 as the opening region 59B. Fig.16 In the example shown, four openings 59B2 are formed. The ceiling portion 59A2 is an example of a "ceiling portion" according to the technique of the present invention.

[0137] The plurality of openings 59B2 allow light from the power switch 15 to pass therethrough. The size of each of the plurality of openings 59B2 is set to be able to suppress entry of a finger F. Fig.16 In the example shown, each of the plurality of openings 59B2 is circular and has a diameter of 10 mm or less.

[0138] As described above, in this modified example, the ceiling portion 59A2 is formed on the restricting portion 59, and a plurality of openings 59B2 are formed on the ceiling portion 59A2. Thus, when the accessory 50 is mounted on the indicator 14, even if the user's finger F attempts to approach the power switch 15 by mistake, it is covered by the ceiling portion 59A2, so that the user's finger F can be further suppressed from contacting the power switch 15. In addition, since a plurality of openings 59B2 are formed, the amount of light from the power switch 15 can be ensured.

[0139] In addition, in the above embodiment, the indicator 14 is provided with the power switch 15, but the technology of the present invention is not limited thereto. Other switches and / or operating dials may be provided on the indicator 14 instead of the power switch 15 or together with the power switch 15.

[0140] Furthermore, in the above embodiment, the peripheral wall 59A is exemplified as the limiting portion 59, but the technology of the present invention is not limited thereto. The limiting portion 59 may be a cylindrical body or a truncated cone body formed around the power switch 15 as long as it can prevent the finger F from contacting the power switch 15. Furthermore, the limiting portion 59 may be a collection of a plurality of columns disposed around the power switch 15.

[0141] In the above embodiment, an example in which the elliptical opening 59B1 is formed in the restricting portion 59 is described, but the technology of the present invention is not limited thereto. The opening 59B1 may be a circular opening with a diameter of 10 mm or less, or may be a slit-shaped opening.

[0142] Furthermore, the object to which the accessory 50 as the switch cover is attached is not limited to the camera 10, and may be, for example, a small electronic device or a toy.

[0143] Furthermore, in the above-mentioned embodiments, the accessory 50 and the camera 10 are connected by a rope S, but the technology of the present invention is not limited thereto. For example, the accessory 50 and the camera 10 may be connected by a member other than the rope S (for example, a chain). Furthermore, the accessory 50 and the camera 10 do not need to be connected, and the accessory 50 may be prepared according to the scene in which the accessory 50 is needed.

[0144] Furthermore, the accessory 50 may be sold as a set with the camera 10 , or the user may obtain the accessory 50 sold separately from the camera 10 .

[0145] Furthermore, in the above-mentioned embodiments, the frame portion 52 is described as an example of a circular ring-shaped frame, but the technology of the present invention is not limited thereto. For example, the frame portion 52 may be rectangular.

[0146] Furthermore, in the above-mentioned embodiments, the case 12 is described as having a substantially oval shape with rounded corners, but the technology of the present invention is not limited thereto. The case 12 may be spherical, spindle-shaped, or quadrilateral.

[0147] In the above embodiments, the indicator 14 is provided on the upper portion of the housing 12 of the camera 10, but the technology of the present invention is not limited thereto. The configuration of the indicator 14 is not particularly limited, and for example, it can be provided on the right side or left side of the housing 12.

[0148] Furthermore, in the above-mentioned embodiments, the shutter button 28 is described as a physical button, but the technology of the present invention is not limited thereto. For example, the shutter button 28 may be displayed on a touch panel display.

[0149] Furthermore, in the above-mentioned embodiments, the first mounting guide 54B and the second mounting guide 54C of the mounting portion 54 hold the side surface of the indicator 14 when the accessory 50 is mounted on the indicator 14, but the technology of the present invention is not limited thereto. As long as the accessory 50 can be freely attached and detached to the indicator 14 via the mounting portion 54, it will not be necessary.

[0150] For example, the mounting portion 54 may be mounted by fitting a protrusion provided on the mounting portion 54 into a recess provided on the indicator 14. In this case, the user can confirm that the accessory 50 is mounted on the indicator 14 by the sense of engagement during the fitting.

[0151] Furthermore, when the accessory 50 is mounted on the indicator 14, the indicator 14 is mounted from above and then the accessory 50 is rotated in a direction perpendicular to the mounting direction (i.e., twisted) to fix the accessory 50 to the indicator 14. Furthermore, for example, a clamping mechanism is provided on the mounting portion 54, and the accessory 50 is mounted by gripping the indicator 14 with claws of the clamping mechanism.
