[0022] An example of an embodiment of a camera according to the technology of the present disclosure will be described with reference to the accompanying drawings.

[0023] In the following description, for convenience of explanation, the front-rear direction (also called the depth direction), width direction, and height direction of the camera 10 are indicated by three arrows, X, Y, and Z. First, the height direction is indicated by arrow Y, and the direction indicated by arrow Y is the upward direction of the camera 10, and the opposite direction is the downward direction. The width direction is indicated by arrow X perpendicular to arrow Y, and the direction indicated by arrow X is the rightward direction of the camera 10, and the opposite direction is the leftward direction. The front-rear direction is indicated by arrow Z perpendicular to arrow Y and arrow X, and the direction indicated by arrow Z is the forward direction of the camera 10, and the opposite direction is the backward direction. That is, the direction toward the subject along the optical axis K (see FIG. 3) in the camera 10 is the forward direction. In the following description, expressions using sides such as upper side, lower side, left side, right side, front side, and rear side have the same meaning as expressions using directions.

[0024] As an example, as shown in FIG. 1, camera 10 is an imaging device that captures an image of a subject. With camera 10, for example, a user presses a shutter button to capture an image of the subject. With camera 10, still images or videos including an image of the subject can be obtained. Camera 10 is small in size (for example, small enough to fit in the palm of an adult's hand) compared to general digital cameras or instant cameras, and can be easily handled by a user. Camera 10 is an example of a "camera" according to the technology of the present disclosure.

[0025] The camera 10 includes a housing 12. The housing 12 houses an image sensor 30 (see FIG. 8) and electronic components for realizing the image capturing function of the camera 10. The housing 12 has a rounded design as a whole, as will be described later in detail. That is, the outer periphery of the housing 12 is mainly curved, and the housing 12 has a substantially egg-shaped appearance. The housing 12 is provided with an opening 16. The opening 16 allows subject light to enter the photographing lens 20. In the example shown in FIG. 1, the opening 16 exposes the lens unit 18 to the outside. The lens unit 18 includes the photographing lens 20 and a holding frame 18A that holds the photographing lens 20. Here, exposing the lens unit 18 includes a state in which the lens unit 18 is directly exposed, and also includes a state in which the lens unit 18 is covered by a cover member or the like to an extent that does not affect the image capturing of the subject.

[0026] In addition, when the side of the housing 12 on which the opening 16 is provided is defined as the front surface 12A of the housing 12, a speaker unit 24 and a flash unit 26 are provided on the front surface 12A. In the speaker unit 24, various operation sounds (for example, electronic sounds simulating the sound of a shutter being released) are output from a sound source (not shown) provided inside the housing 12. In the example shown in FIG. 1, sound is output through three through holes 24A. In addition, in the flash unit 26, light is emitted from a light source (not shown) provided inside the housing 12 to a subject. In the example shown in FIG. 1, the light source is covered by a cover member 26A provided on the housing 12.

[0027] An indicator 14 is provided on the upper part of the housing 12. The exterior of the indicator 14 is formed from a translucent material, and emits light from a light source 14A provided inside the indicator 14 to the outside. The indicator 14 is capable of reporting information about the camera 10 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" according to the technology of the present disclosure.

[0028] For example, if the camera 10 has a function for communicating with the outside, the indicator 14 emits light at a preset emission interval and in a preset emission color while the camera 10 is communicating with the outside. In the example shown in Fig. 1, the smartphone 100 and the camera 10 are communicating wirelessly. In this case, the indicator 14 emits light to indicate that the camera 10 is communicating with the outside.

[0029] As a result of the wireless communication, data indicating the captured image IM obtained by the camera 10 is transmitted to the smartphone 100, and the user can check the captured image IM on the smartphone 100.

[0030] Note that, here, as an example of communication between the camera 10 and the outside, an example in which data representing the captured image IM is transmitted to the smartphone 100 has been given, but this is merely one example, and a form in which data representing the captured image IM is transmitted to an external printing device may also be used. Also, for example, a form in which software (e.g., a control program for the camera 10) is downloaded to the camera 10 may also be used.

[0031] In addition, although the state in which the camera 10 is communicating with the outside has been given as an example here as information on the camera 10 that is notified by the indicator 14, this is merely one example. For example, the indicator 14 may notify, as an operating state of the camera 10, that the camera 10 is broken, that a software update is being performed on the camera 10, and the like.

[0032] 1, the indicator 14 is a portion that protrudes upward from the housing 12. The indicator 14 has a trapezoidal shape when the housing 12 is viewed from the front.

[0033] In addition, a through hole may be formed in the exterior of the indicator 14 at a position corresponding to the light source. This allows the light emitted from the light source to be easily emitted to the outside through the through hole. As a result, the light emitted by the indicator 14 can be easily visually recognized from the outside.

[0034] Furthermore, a power switch 15 is provided on the top surface 14B of the indicator 14. The power switch 15 is provided on the top surface 14B of the indicator 14 along the left-right direction (the X direction shown in FIG. 1). The power switch 15 can be pressed several times (e.g., three times) to turn on the power of the camera 10. The power switch 15 can be pressed and held for several seconds (e.g., three seconds) to turn off the power of the camera 10.

[0035] Further, a bottom surface 12C is formed on the lower part of the housing 12. At least a part of the area including the center of the bottom surface 12C is configured as a flat surface. This allows the camera 10 to be placed on a desk or the like. Here, a flat surface includes a completely flat surface, and includes a surface having a flatness sufficient to allow the housing 12 to be placed thereon.

[0036] 2, when the side of the housing 12 opposite the front face 12A is the rear face 12B (i.e., when the side facing the front face 12A in the optical axis direction of the photographing lens 20 is the rear face 12B), a shutter button 28 is provided on the rear face 12B. The shutter button 28 can be pressed toward the front face 12A. As described above, when the user presses the shutter button 28, an image of the subject is captured by the camera 10.

[0037] Also, in general digital cameras, a display unit (e.g., a liquid crystal display or the like) for checking the subject image is often mounted on the back surface. On the other hand, in this embodiment, a display unit for checking the subject image is not provided on back surface 12B of camera 10. Of course, in camera 10, a display unit for a purpose other than checking the subject image (e.g., a display unit showing the remaining battery level) may be provided on back surface 12B.

[0038] Furthermore, a reception unit 29 is provided on the rear surface 12B of the housing 12. The reception unit 29 is a terminal that receives an electrical connection with an external device, and is, for example, a Universal Serial Bus (USB) terminal. Through the reception unit 29, the battery of the camera 10 is charged, and wired communication between the camera 10 and the external device is performed.

[0039] As described above, the camera 10 is a small camera compared to general digital cameras and the like. Therefore, in order to further improve the convenience of the camera 10, as an example shown in Fig. 2, the camera system 1 according to this embodiment includes the camera 10 and an accessory 50. The camera system 1 is an example of a "camera system" according to the technology of the present disclosure.

[0040] The accessory 50 is a part that is attached to the camera 10 and can be attached to the camera 10. In the example shown in Fig. 2, the accessory 50 is connected to the camera 10 via a string S. Specifically, one end of the string 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 "attachment" according to the technology of the present disclosure.

[0041] The accessory 50 includes a frame portion 52, an attachment portion 54, and a pair of string attachment portions 56A and 56B. The frame portion 52 is a frame-shaped portion, and functions as a frame that defines the field of view when the accessory 50 functions as a viewfinder. The attachment portion 54 is a portion for attaching the accessory 50 to the housing 12 of the camera 10. In the example shown in Fig. 2, the frame portion 52 is an annular frame.

[0042] The pair of string attachment parts 56A and 56B are parts for attaching a string S to the accessory 50. In the example shown in FIG. 2, the other end of the string S is attached to the string attachment part 56A provided on the side surface of the accessory 50.

[0043] Accessory 50 functions as a grip for carrying camera 10. That is, camera 10 can be easily carried by placing fingers inside frame 52 of accessory 50 or by hanging the frame of frame 52 on a hook.

[0044] 3, the frame portion 52 has a first protrusion 52A and a second protrusion 52B on the upper surface side. Although details will be described later, when the accessory 50 functions as a stand for the camera 10, the first protrusion 52A and the second protrusion 52B come into contact with the lower surface 12C of the camera 10. The first protrusion 52A and the second protrusion 52B are an example of the "multiple support protrusions" according to the technology of the present disclosure.

[0045] Further, the frame 52 has a first leg 52C and a second leg 52D on the lower surface side. The first leg 52C and the second leg 52D abut on the installation surface of the accessory 50 when the accessory 50 functions as a stand.

[0046] 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 inside 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 is visible. The mounting portion 54 is an example of a "mounting portion" according to the technology of the present disclosure, the frame portion 52 is an example of a "frame" according to the technology of the present disclosure, and the through hole 54A is an example of a "through hole" according to the technology of the present disclosure.

[0047] The first attachment guide portion 54B and the second attachment guide portion 54C are portions on a wall protruding from an end portion of the attachment portion 54. The first attachment guide portion 54B and the second attachment guide portion 54C guide the attachment when the accessory 50 is attached to the indicator 14. Furthermore, the first attachment guide portion 54B and the second attachment guide portion 54C hold the indicator 14 from the side when the accessory 50 is attached to the indicator 14.

[0048] 3, the first mounting guide portion 54B and the second mounting guide portion 54C are provided as a pair at the end of the mounting portion 54. The first mounting guide portion 54B and the second mounting guide portion 54C are formed as arc-shaped walls. The shapes of the inner wall surfaces of the first mounting guide portion 54B and the second mounting guide portion 54C correspond to the side shape of the indicator 14.

[0049] As an example, as shown in Fig. 4, the accessory 50 is attached to the camera 10. The accessory 50 is attached to the indicator 14 of the camera 10 via the attachment portion 54. Specifically, the accessory 50 is attached to the indicator 14 from above the indicator 14. In this case, the first attachment guide portion 54B and the second attachment guide portion 54C of the attachment portion 54 hold the side surfaces of the indicator 14. In this way, the accessory 50 is attached to the indicator 14.

[0050] When the indicator 14 emits light in this state, the light emitted from the indicator 14 toward the upper side passes through the through hole 54A of the attachment portion 54. Then, a part of the light that passes through the through hole 54A illuminates the inside of the frame portion 52 of the accessory 50. For example, an area U on the inside of the frame portion 52 is illuminated by the light emitted from the indicator 14. In this way, the accessory 50 is capable of irradiating the light emitted from the indicator 14 toward the inside of the frame portion 52.

[0051] 5, as an example, light emitted from indicator 14 is irradiated onto the inside of frame 52 of accessory 50, and the light is reflected on the inside of frame 52. A part of the reflected light travels in a direction toward user's eye E. This allows the user to visually recognize the light emitted from indicator 14.

[0052] Next, an example of how the camera 10 according to this embodiment is used will be described. As an example, as shown in FIG. 6, the user holds the camera 10 by pinching the housing 12 with his / her fingers from the front and back. Specifically, the index finger F1 and middle finger F2 are placed on the housing 12 from the front 12A side toward the rear 12B side, and the thumb F3 is placed on the rear 12B side toward the front 12A side. On the front 12A of the housing 12, the index finger F1 and middle finger F2 pinch the opening 16. In particular, the middle finger F2 is placed on the front 12A so as to support the opening 16 from below. On the other hand, on the rear 12B side, the user places the thumb F3 on the shutter button 28.

[0053] As another way of holding the camera 10, the user may place the middle finger F2 on the right side of the opening 16 and the index finger F1 on the left side of the opening 16. The user may also hold the camera 10 by pinching the housing 12 with his / her fingers from above and below. Furthermore, the camera 10 may of course be held or operated with both hands of the user.

[0054] The accessory 50 functions as a viewfinder when attached to the camera 10. For example, the frame 52 of the accessory 50 serves as a guide for checking the shooting range when the user looks into the viewfinder. Here, since the frame 52 of the accessory 50 is not provided with an optical element such as a lens, the frame 52 functions as a simple viewfinder (so-called sports viewfinder).

[0055] The frame portion 52 functions as a simple viewfinder, as shown in FIG. 6, means that when used as a viewfinder, the frame serves as a guide for the user to check the shooting range, thereby enabling the user to check the orientation of the camera 10 relative to the subject and the width in which the surroundings of the subject are captured, thereby enabling the user to check the shooting range.

[0056] Furthermore, the accessory 50 may function not only as a simple viewfinder, but also as a viewfinder having an optical system such as a real image or virtual image viewfinder. In this case, various optical elements are provided on the frame 52 of the accessory 50.

[0057] In addition, when the accessory 50 functions as a finder, the indicator 14 is arranged at a position where the user can see it when the user looks through the finder. The position where the user can see the indicator 14 is set to a position where the distance L between the user's eye E and the accessory 50 as a finder is appropriate. The field of view ER in the frame portion 52 when looking through the finder at this position corresponds to the imaging range IR of the camera 10. That is, the field of view ER and the imaging range IR match. Note that the match includes a complete match, and includes an error to an extent that is acceptable in the technical field to which the technology of the present disclosure belongs. In this way, when the user uses the finder, the exposed part of the indicator 14 is visually recognized by the user, and the indicator 14 becomes an indicator indicating that the field of view of the subject looking through the finder corresponds to the imaging range.

[0058] Then, after looking through the viewfinder to check the imaging range, the user presses the shutter button 28 (see the arrow in FIG. 6), causing the camera 10 to capture an image.

[0059] As an example, as shown in FIG. 7 and FIG. 8, the accessory 50 also functions as a stand on which the camera 10 can be placed. With the accessory 50 installed on the installation surface G, the camera 10 is placed 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 surface 12A side of the camera 10, and the frame portion 52 of the accessory 50 is located on the rear surface 12B side of the camera 10. The annular frame of the frame portion 52 is large enough to hold the periphery of the lower surface 12C of the housing 12 of the camera 10. Furthermore, the first protrusion 52A and the second protrusion 52B provided on the frame portion 52 are capable of abutting against the lower portion of the camera 10. In other words, the first protrusion 52A and the second protrusion 52B become support points that support the camera. This prevents the camera 10 from coming off the stand or being supported in an unstable state.

[0060] In addition, when the camera 10 is placed on the accessory 50 functioning as a stand, the optical axis K of the camera 10 faces upward relative to the horizontal direction. That is, the camera 10 is given an elevation angle by being placed on the stand. Here, the height of the frame 52 from the installation surface G varies along the circumferential direction of the frame 52. Specifically, the height of the frame 52 is higher on the mounting section 54 side. That is, when the accessory 50 is viewed from the side, the height of the mounting section 54 is higher than the height of the frame 52. For this reason, when the camera 10 is placed on the accessory 50 functioning as a stand, the optical axis K of the camera 10 is inclined in a direction in which the subject side of the optical axis K is away from the installation surface G. In this way, the accessory 50 functioning as a stand can mount the camera 10 in a position in which the optical axis K of the camera 10 is inclined relative to the horizontal direction.

[0061] As an example, as shown in FIG. 9, the accessory 50 functioning as a stand has a shape that allows the tilt angle to be adjusted with respect to the horizontal direction of the optical axis K. That is, the tilt angle is adjusted by the user rotating the camera 10 in a direction that changes the elevation angle with respect to the accessory 50. Specifically, when the accessory 50 is viewed from the side, a continuous inclined surface is formed from the mounting part 54 to the frame part 52. Also, as described above, the height of the mounting part 54 is higher than the frame part 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 with respect to the horizontal direction.

[0062] 9 shows an example in which the user tilts the camera 10 upward. That is, the camera 10 is moved in a direction in which the optical axis K1 of the camera 10 is adjusted to the optical axis K2. Then, the inclination angle θ1 with respect to the line HZ along the horizontal direction before the adjustment is changed to the inclination angle θ2 after the adjustment. In this way, the optical axis K of the camera 10 is adjustable with respect to the horizontal direction.

[0063] As described above, the camera system 1 according to this embodiment includes the camera 10 having the indicator 14, and the accessory 50 that can be attached to the camera 10. When the accessory 50 is attached to the camera 10, it functions as a finder for checking the shooting range of the camera 10. The light emitted from the indicator 14 can be irradiated onto the inside of the frame of the finder. As a result, compared to a conventional accessory that functions as a finder, the light from the indicator 14 can be illuminated inside the frame of the finder, making it easier for the user to visually recognize the light emitted by the indicator 14.

[0064] Furthermore, for example, compared to a configuration in which the camera and the viewfinder are always integrated, the accessory 50 attached to the camera 10 functions as a viewfinder, so that the camera 10 can be made smaller.

[0065] In the conventional accessory viewfinder, the light-emitting unit was located outside the viewfinder frame. Therefore, even if the light emission was increased, it was difficult to see in bright surroundings such as under the blazing sun, and it was also difficult to see the light emission when the eye was close to the eyepiece or when wearing glasses. Therefore, with the above configuration, the light emission is irradiated within the frame of the accessory viewfinder, making it easier for the user to see the light emitted by the light-emitting unit.

[0066] Furthermore, in the camera system 1 according to this embodiment, the accessory 50 has a through hole 54A formed in an attachment portion 54 for the camera 10. Then, 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 portion 52. This makes it easier for the user to visually recognize the light emitted by the indicator 14 with a simple configuration, compared to a case in which a light guiding member is provided in the accessory 50.

[0067] In addition, in the camera system 1 according to this embodiment, the frame portion 52 of the accessory 50 serves as a guide for checking the shooting range, and the accessory 50 functions as a simple finder without a lens. As a result, since the finder defines the field of view with its frame shape, the finder function is realized with a simple configuration compared to a finder equipped with an optical element such as a lens.

[0068] Furthermore, if an optical element is provided in the frame 52, the light from the indicator 14 may be deflected or diffracted by the optical element, making it difficult for the user to visually recognize the emission of the indicator 14. In this configuration, the accessory 50 functions as a simple finder without a lens, making it easier for the user to visually recognize the light from the indicator 14.

[0069] Furthermore, in the camera system 1 according to this embodiment, the accessory 50, in addition to functioning as a viewfinder, also functions as a grip for carrying the camera 10, or as a stand on which the accessory 50 can be placed. As a result, even when the accessory 50 is not attached, other functions of the accessory 50 can be used, improving the usability of the accessory 50 compared to an accessory 50 having only a single function.

[0070] Furthermore, in the camera system 1 according to this embodiment, the accessory 50 also functions as a stand on which the camera 10 can be placed. This allows the camera 10 to be installed more stably than when the camera 10 is installed directly on the installation surface G without using a stand. This configuration is effective, for example, when the camera 10 is used as a fixed camera.

[0071] Furthermore, in the camera system 1 according to this embodiment, the accessory 50, which functions as a stand, is capable of mounting the camera 10 in a position in which the optical axis K of the camera 10 is tilted with respect to the horizontal direction. This allows the imaging range of the camera 10 to be changed by tilting the optical axis K of the camera 10 with respect to the horizontal direction, and further allows the tilted attitude of the camera 10 to be stably maintained. For example, by mounting the camera 10 with the optical axis K of the camera 10 tilted in a direction away from the installation surface G, it is possible to include many subjects (e.g., people) desired by the user in the imaging range.

[0072] In addition, in the camera system 1 according to this embodiment, the accessory 50 functioning as a stand has a shape that allows adjustment of the inclination angle θ with respect to the horizontal direction of the optical axis K. This allows the inclination angle of the camera 10 to be adjusted, making it possible to capture images at an inclination angle desired by the user.

[0073] In addition, in the camera system 1 according to the present embodiment, the height of the frame 52 from the installation surface G of the accessory 50 functioning as a stand varies in the circumferential direction of the frame 52, making it possible to adjust the inclination angle. This makes it possible to adjust the inclination angle of the camera 10, making it possible to capture an image at an inclination angle desired by the user.

[0074] Furthermore, in the camera system 1 according to this embodiment, the frame portion 52 of the accessory 50 serves as a guide for checking the shooting range, and the accessory 50 has a first protrusion 52A and a second protrusion 52B that support the camera 10 when used as a stand. The first protrusion 52A and the second protrusion 52B are disposed on the frame portion 52. As a result, the first protrusion 52A and the second protrusion 52B abut against and support the lower portion of the camera 10, so that the camera 10 placed on the accessory 50 functioning as a stand is stably supported.

[0075] Furthermore, in the camera system 1 according to this embodiment, the camera 10 has a communication function, and when the camera 10 is communicating with an external device, the indicator 14 emits light to notify that the camera 10 is communicating. When the camera 10 is communicating with an external device, it may not be suitable for capturing images. The user can determine whether the camera 10 is in a suitable state for capturing images by visually checking the inside of the frame 52 of the accessory 50, which functions as a viewfinder.

[0076] Furthermore, in the camera system 1 according to this embodiment, the indicator 14 is disposed at a position where the light emitted by the indicator 14 is visible to the user when the user looks through a finder attached to the camera 10. When the finder is used, the indicator 14 is visible to the user, so that imaging is achieved in the imaging range desired by the user. In other words, when the finder is used, the indicator 14 serves as an indicator showing that the field of view seen through the finder corresponds to the imaging range, so that imaging is achieved in the imaging range desired by the user.

[0077] (First Modification) In the above embodiment, an example in which the light from the indicator 14 is irradiated to the inside of the frame portion 52 through the through hole 54A has been described, but the technology of the present disclosure is not limited to this. In this first modified example, a part of the accessory 50 is formed of a light-transmitting material.

[0078] 10, a light transmitting portion 58 is formed in the mounting portion 54 of the accessory 50. The light transmitting portion 58 transmits light emitted from the indicator 14. The light transmitting portion 58 is formed of a light transmitting material that is transparent to visible light. The light transmitting material is, for example, an acrylic resin.

[0079] 10, 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 part of the light illuminates the inside of the frame portion 52 of the accessory 50. For example, an area U on the inside of the frame portion 52 is illuminated by the light emitted from the indicator 14. In this way, the accessory 50 is capable of irradiating the light emitted from the indicator 14 onto the inside of the frame portion 52.

[0080] As described above, in this first modified example, a part of the accessory 50 is formed from a light-transmitting material, and light from the indicator 14 can be irradiated onto the inside of the frame portion 52. This allows the inside of the frame of the viewfinder to be illuminated with light from the indicator 14, making it easier for the user to visually recognize the light emitted by the indicator 14.

[0081] In addition, in the first modified example, light is scattered not only inside the frame portion 52 but also in the light transmitting portion 58, so that the accessory 50 itself partially emits light, making it easier for the user to visually recognize the emitted light of the indicator 14.

[0082] In the first modified example, a part of the accessory 50 is made of a light-transmitting material, but the technology of the present disclosure is not limited to this. For example, the entire accessory 50 may be made of a light-transmitting material.

[0083] (Second Modification) In the above embodiment, an example in which the light from the indicator 14 is irradiated to the inside of the frame portion 52 through the through hole 54A has been described, but the technology of the present disclosure is not limited to this. In the present second modified example, the accessory 50 is provided with a light guide member 60.

[0084] As an example, as shown in FIG. 11, 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 propagating the light from the indicator 14 inside. In the example shown in FIG. 11, 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 an optical path R formed inside the prism 61. Specifically, the light emitted from the light source 14A of the indicator 14 is reflected by a first reflecting surface 62 and further reflected by a second reflecting surface 64. Then, the light reflected by the second reflecting surface 64 is emitted toward the inside of the frame portion 52.

[0085] A part of the light emitted from the indicator 14 illuminates the inside of the frame portion 52 of the accessory 50 via the light-guiding member 60. For example, an area U inside the frame portion 52 is illuminated by the light emitted from the indicator 14. In this manner, the accessory 50 is capable of irradiating the light emitted from the indicator 14 onto the inside of the frame portion 52.

[0086] As described above, in the second modified example, the light guide member 60 is provided on the accessory 50. Light from the indicator 14 can be irradiated to the inside of the frame portion 52 via the light guide member 60. This allows the inside of the frame of the viewfinder to be illuminated with light from the indicator 14, making it easier for the user to visually recognize the light emitted by the indicator 14.

[0087] In addition, in the second modified example, light from the indicator 14 is irradiated to the inside of the frame portion 52 by the light guiding member 60, so that a large amount of light can be guided to the frame portion 52, making it easier for the user to visually recognize the emitted light.

[0088] In the second modified example, the prism 61 is used as the light-guiding member 60, but the technology of the present disclosure is not limited to this. As an example, as shown in FIG. 12, a fiber 66 is used as the light-guiding member 60. One end of the fiber 66 is provided at a position facing the light source 14A of the indicator 14, and the other end of the fiber 66 is provided inside the frame 52. Light from the indicator 14 propagates inside the fiber 66, and is emitted toward the inside of the frame 52.

[0089] (Other embodiments) As described above, the indicator 14 of the camera 10 is provided with the power switch 15. Specifically, the power switch 15 is provided on the upper surface 14B of the indicator 14. The power switch 15 is capable of emitting light depending on the operation state. The power switch 15 is an example of an "operation unit" according to the technology of the present disclosure.

[0090] If the power switch 15 is operated by the user erroneously, it may cause the power of the camera 10 to be turned off in a situation unintended by the user, such as while the camera 10 is being used or while communicating with the outside. Therefore, it may be necessary to provide a switch cover that prevents the power switch 15 from being operated erroneously.

[0091] A known prior art for a switch cover is a switch cover that is made up of a box-shaped frame body that is rectangular in plan view and a lid that opens and closes an opening defined by the frame body. This switch cover is attached to a camera in a manner that accommodates a switch inside the box-shaped frame body. The opening has a size that allows a user's finger to be inserted. When the switch cover is attached to the camera and the switch is not operated, the opening is closed by the lid. When the user operates the switch, the lid is opened and the user's finger is inserted through the opening to press the switch. This suppresses erroneous operation by the user when the lid of the opening is closed. However, in this configuration, it is necessary to provide a mechanism for opening and closing the lid (e.g., a hinge mechanism) in the switch cover, and providing the mechanism for opening and closing the lid may restrict the degree of freedom of design, such as the shape and size of the switch cover. In particular, in a case where the housing of the camera 10 according to this embodiment is small and the body of the camera 10 has a distinctive design, the shape and size restrictions may make it difficult to match the design of the switch cover to the design of the camera 10.

[0092] Another known prior art for switch covers is a cover made of soft resin that covers the entire switch. In this case, when a user presses down a switch, if a certain external force is applied from the user's finger, the switch cover elastically deforms and the switch is pressed down through the cover. For this reason, the switch cover does not deform or only deforms a small amount with a weak force such as a light touch, so that erroneous operation by the user is suppressed. However, such a switch cover that covers the entire switch has the following problem. That is, some camera switches emit light depending on the operation state. When a switch cover that covers the entire switch is used for a switch that has a light-emitting function, the color of the switch cover needs to be made of a material that is light-transmitting in order to ensure the visibility of the light, which results in color restrictions. As with the above-mentioned prior art, color restrictions restrict the freedom of design of the switch cover.

[0093] 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. As an example, as shown in Fig. 13, the accessory 50 is attached to the indicator 14. Consider a case in which the user in this state accidentally brings his / her finger F close to the power switch 15 from above the indicator 14.

[0094] 14 as an example, power switch 15 is provided in a state of protruding from one surface of camera 10 (here, upper surface 14B of indicator 14). Accessory 50 is provided with a restricting portion 59. Restricting portion 59 restricts contact with power switch 15 when accessory 50 is attached to camera 10. Restricting portion 59 is an example of a "restricting portion" according to the technology of the present disclosure.

[0095] The restricting portion 59 is disposed at least partially around the power switch 15. In the example shown in FIG. 14, the restricting portion 59 is a peripheral wall 59A surrounding the periphery of the power switch 15. The peripheral wall 59A is an example of a "peripheral wall" according to the technology of the present disclosure. When the accessory 50 is attached to the indicator 14, the height h1 of the restricting 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 restricting portion 59 has a height higher than the protruding amount of the power switch 15. As a result, when the finger F approaches the power switch 15, the finger F first comes into contact with the upper portion of the restricting portion 59, and is prevented from coming into contact with the power switch 15. As a result, the finger F or the like is prevented from erroneously coming into contact with the power switch 15.

[0096] The restricting portion 59 has sufficient rigidity against the pressing force by the user, and the height h1 of the restricting portion 59 maintains a height capable of preventing contact with the power switch 15 even when the restricting portion 59 is pressed by the finger F. In other words, even when the restricting portion 59 is pressed by the finger F, the opening region 59B is spaced apart from the power switch 15 by a certain distance or more.

[0097] 15, when the power switch 15 is viewed from a top portion 59A1 in the height direction of the restricting portion 59 in a plan view, an opening region 59B is formed in the restricting portion 59. The opening region 59B is formed so as to overlap at least a portion of the power switch 15. The opening region 59B transmits light emitted by the power switch 15. The top portion 59A1 is an example of a "top portion" according to the technology of the present disclosure, and the opening region 59B is an example of an "opening region" according to the technology of the present disclosure.

[0098] As described above, the peripheral wall 59A surrounds the power switch 15. In the example shown in Fig. 15, the opening region 59B is one opening 59B1 defined by the peripheral wall 59A. The opening 59B1 is an example of an "opening" according to the technology of the present disclosure.

[0099] The opening area 59B is sized to prevent the entry of the finger F toward the power switch 15. Here, the size of the user's finger F refers to the average width of an adult's index finger (here, the distance in a direction perpendicular to the longitudinal direction of the finger when viewed from the back of the hand), and in particular, refers to the average width of the base of the index finger nail (the part of the nail closest to the first joint). The size that prevents the entry of the finger F refers to a size equal to or smaller than this average.

[0100] Here, the opening 59B1 is elliptical in plan view. The distance t in the minor axis direction of the opening 59B1 is a distance that can prevent the finger F from touching the power switch 15 and ensures the amount of light from the indicator 14. For example, the distance t is 10 mm or less.

[0101] In addition, although the opening 59B1 is described here as an elliptical shape, the technology of the present disclosure is not limited thereto. The opening 59B1 may be an oval shape. The opening 59B1 may also be a rectangle. In this case, the distance t is the distance in the direction of the short side of the rectangle.

[0102] In addition, the opening 59B1 is open to the outside. In other words, the inside of the opening 59B1 is not filled with resin, and a lid is not attached to the opening 59B1.

[0103] In addition, when the accessory 50 is attached to the indicator 14, a member including an opposing portion facing the opening region 59B is provided on an extension line L1 of a straight line extending along the height direction of the regulating portion 59 from the power switch 15 toward the opening 59B1.

[0104] In the example shown in FIG. 14, frame portion 52 is provided above restriction portion 59. As described above, as an example, frame portion 52 has an annular shape. An upper arc portion 52E of annular frame portion 52 is provided at a position facing opening 59B1. Frame portion 52 has an annular shape with a radial direction being a direction along a straight line. Frame portion 52 is an example of a "member" according to the technology of the present disclosure, and upper arc portion 52E is an example of a "facing portion" according to the technology of the present disclosure.

[0105] The presence of the arc portion 52E makes it difficult for the finger F or the like to approach the restricting portion 59 from above. For example, consider a case where the finger F approaches the opening 59B1 from the tip side of the finger F. In this case, the finger F interferes with the upper arc portion 52E of the ring of the frame portion 52 above the restricting portion 59 (see FIG. 14). For this reason, the finger F is restricted from approaching the opening 59B1 in a position in which the nail of the finger F is inserted into the opening 59B1, and the finger F is prevented from accidentally touching the power switch 15.

[0106] According to the accessory 50 of this embodiment, the power switch 15 is provided on the camera 10, and the accessory 50 is attached to the camera 10. The accessory 50 is provided with a restricting portion 59. The restricting portion 59 has a height h1 that is greater than the protrusion amount h2 of the power switch 15. Furthermore, the restricting portion 59 is provided with an opening 59B1 that overlaps with a part of the power switch 15 in a plan view. The opening 59B1 is sized to transmit light from the power switch 15 and to prevent the user's finger from entering the opening.

[0107] As a result, even if the user's finger F accidentally approaches the power switch 15 while the accessory 50 is attached to the indicator 14, the finger F will first come into contact with the restricting portion 59, and thus the finger F is prevented from coming into contact with the power switch 15. That is, there is no need to provide a lid on the opening 59B1, and the degree of freedom in the design (e.g., shape and size) of the accessory 50 is improved. For example, the accessory 50 can be designed to match the camera 10. In addition, since light from the power switch 15 is irradiated to the outside through the opening 59B1, the degree of freedom in the selection of the material of the restricting portion 59 is realized. For example, a material other than a transparent material can be adopted.

[0108] Furthermore, even when the restricting portion 59 is pressed by a finger F, the position of the top portion 59A1 is spaced a certain distance or more from the power switch 15. This prevents the finger F or the like from accidentally contacting the power switch 15. For example, depending on the pressing force, the power switch 15 may be pressed through the cover even in the case of an unintended operation. In this configuration, even when pressed by a finger F, the restricting portion 59 ensures a sufficient distance between the power switch 15 and the top portion 59A1 of the restricting portion 59, so that the finger F is further prevented from accidentally contacting the power switch 15.

[0109] According to the accessory 50 of this embodiment, the restricting portion 59 is the peripheral wall 59A. The opening 59B1 is defined by the peripheral wall 59A. This allows the peripheral wall 59A to distribute and support the force of the finger F approaching the power switch 15, and also prevents the finger F from approaching from multiple directions, such as front, back, left, and right. As a result, the finger F is prevented from approaching the power switch 15.

[0110] Furthermore, in the accessory 50 according to this embodiment, the opening 59B1 is elliptical, and the distance t in the minor axis direction is 10 mm or less. When the finger F touches the power switch 15, it is generally difficult for a human finger to pass through a gap of 10 mm and touch the power switch 15. Therefore, the finger F is prevented from accidentally touching the power switch 15.

[0111] Furthermore, according to the accessory 50 of this embodiment, when the accessory 50 is attached, a frame portion 52 is provided above the restricting portion 59. An upper arc portion 52E of the frame portion 52 is provided at a position facing the opening region 59B. This restricts the position of the finger F such that the nail of the finger F is inserted into the opening region 59B, and prevents the finger F from accidentally touching the power switch 15.

[0112] Moreover, according to the accessory 50 according to this embodiment, the frame 52 is an annular member that includes the upper arc portion 52E and has the extension line L1 as a radial direction. This simplifies the configuration of the accessory 50 compared to a case where a separate member for regulating the position of the finger F or the like is provided at a position opposite the opening region 59B.

[0113] In the above embodiment, an example in which the opening 59B1 is formed as the opening region 59B has been described, but the technology of the present disclosure is not limited to this. In this modification, a plurality of openings 59B2 are formed as the opening region 59B. The plurality of openings 59B2 is an example of the "plurality of openings" according to the technology of the present disclosure.

[0114] As an example, as shown in Fig. 16, the restricting portion 59 has a ceiling portion 59A2 formed on a top portion 59A1. The ceiling portion 59A2 covers the power switch 15. The ceiling portion 59A2 has a plurality of openings 59B2 formed as an opening region 59B. In the example shown in Fig. 16, four openings 59B2 are formed. The ceiling portion 59A2 is an example of a "ceiling portion" according to the technology of the present disclosure.

[0115] The plurality of openings 59B2 transmit light from the power switch 15. Moreover, each of the plurality of openings 59B2 has a size capable of preventing the entry of a finger F. In the example shown in Fig. 16, each of the plurality of openings 59B2 is circular and has a diameter of 10 mm or less.

[0116] As described above, in this modification, the restricting portion 59 has a ceiling portion 59A2, and furthermore, a plurality of openings 59B2 are formed in the ceiling portion 59A2. As a result, even if the user's finger F tries to approach the power switch 15 by mistake while the accessory 50 is attached to the indicator 14, the user's finger F is covered by the ceiling portion 59A2, so that the user's finger F is further prevented from touching the power switch 15. Furthermore, since the plurality of openings 59B2 are formed, the amount of light from the power switch 15 is ensured.

[0117] In the above embodiment, an example in which the power switch 15 is provided on the indicator 14 has been described, but the technology of the present disclosure is not limited to this. Instead of the power switch 15, or together with the power switch 15, the indicator 14 may be provided with other switches and / or operation dials, etc.

[0118] In the above embodiment, the peripheral wall 59A is given as an example of the restricting portion 59, but the technology of the present disclosure is not limited thereto. The restricting 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 touching the power switch 15. The restricting portion 59 may also be an assembly of multiple pillars arranged around the power switch 15.

[0119] In the above embodiment, the restricting portion 59 has an elliptical opening 59B1 formed therein, but the technology of the present disclosure is not limited to this. The opening 59B1 may be a circular opening having a diameter of 10 mm or less, or may be a slit-shaped opening.

[0120] Furthermore, the object to which the accessory 50 serving as a switch cover is attached is not limited to the camera 10, but may be, for example, a small electronic device or a toy.

[0121] In addition, in each of the above embodiments, an example in which the accessory 50 is connected to the camera 10 by the string S has been described, but the technology of the present disclosure is not limited to this. For example, the accessory 50 may be connected to the camera 10 by means other than the string S (for example, a chain). Also, the accessory 50 does not need to be connected to the camera 10, and the accessory 50 may be prepared depending on a scene in which the accessory 50 is needed.

[0122] In addition, the accessory 50 may be sold as a set with the camera 10, or the user may obtain the accessory 50 that is sold separately from the camera 10.

[0123] In addition, in each of the above-described embodiments, the frame portion 52 is an annular frame, but the technology of the present disclosure is not limited to this. For example, the frame portion 52 may be rectangular.

[0124] In addition, in each of the above embodiments, the housing 12 has been described as having a generally egg-shaped rounded shape, but the technology of the present disclosure is not limited to this. The housing 12 may be spherical, spindle-shaped, or rectangular.

[0125] In addition, in each of the above embodiments, the camera 10 has been described with the indicator 14 provided on the upper part of the housing 12, but the technology of the present disclosure is not limited to this. The location of the indicator 14 is not particularly limited, and it may be provided on the right side or left side of the housing 12, for example.

[0126] In addition, in each of the above embodiments, the shutter button 28 is a physical button, but the technology of the present disclosure is not limited to this. For example, the shutter button 28 may be displayed on a touch panel display.

[0127] In addition, in each of the above embodiments, when the accessory 50 is attached to the indicator 14, the first attachment guide portion 54B and the second attachment guide portion 54C of the attachment portion 54 hold the side surface of the indicator 14, but the technology of the present disclosure is not limited to this. It is sufficient that the accessory 50 is detachable from the indicator 14 via the attachment portion 54.

[0128] For example, the mounting portion 54 may be attached 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 attached to the indicator 14 by a clicking sensation at the time of fitting.

[0129] Furthermore, when the accessory 50 is attached to the indicator 14, the accessory 50 may be fixed to the indicator 14 by attaching the accessory 50 to the indicator 14 from above and then rotating the accessory 50 in a direction perpendicular to the attachment direction (i.e., twisting the accessory 50). Also, for example, a clip mechanism may be provided on the attachment portion 54, and the accessory 50 may be attached by gripping the indicator 14 with a claw of the clip mechanism.
