[0040] An example of an embodiment of the camera related to the technology of the present utility model will be described with reference to the accompanying drawings.

[0041] In the following description, for ease of explanation, the front-rear direction (also referred to as the depth direction), width direction, and height direction of the camera 10 are represented by three arrows X, Y, and Z. First, the height direction is represented by the arrow Y, the direction of the arrow Y at the part pointed by the 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 the arrow X orthogonal to the arrow Y, the direction pointed by the 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-rear direction, the direction orthogonal to the arrow Y and the arrow X is represented by the arrow Z, the direction pointed by the 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, the direction along the optical axis K (reference Figure 3 ) toward the subject is the front direction. And hereinafter, the meanings of the notations on the use side such as the upper side, lower side, left side, right side, front side, and rear side are the same as those of the notation of the use direction.

[0042] As an example, as Figure 1 shown, the camera 10 is an imaging device that captures a subject. In the camera 10, for example, the subject is captured by the user pressing the shutter button. In the camera 10, a still image or a moving image including the subject image 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 an adult's palm), and the user can easily operate it. The camera 10 is an example of the "camera" related to the technology of the present utility model.

[0043] The camera 10 includes a housing 12. Inside the housing 12, in addition to the imaging element 30 (refer to Figure 8 ), there are also accommodated electronic components and the like for realizing the imaging function of the camera 10. The entire housing 12 has a rounded-corner pattern, and the detailed content will be described later. That is, the outer peripheral surface of the housing 12 is mainly composed of curved surfaces, and the appearance is in a substantially oval shape. An opening 16 is provided in the housing 12. The opening 16 allows subject light to enter the photographic lens 20. In Figure 1 the example shown, the opening 16 exposes the lens unit 18 to the outside. The lens unit 18 is configured to include the photographic lens 20 and a holding frame 18A that holds the photographic lens 20. Here, exposing the lens unit 18 includes a direct exposure method and also includes a method of being covered by a covering member or the like within a range that does not affect the imaging of the subject.

[0044] Moreover, when the side of the housing 12 where 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, an electronic sound simulating the sound of pressing the shutter) are output from a sound source (not shown) provided inside the housing 12. In Figure 1 the example shown, the sound is output via three through holes 24A. And in the flash unit 26, light is emitted from a light source (not shown) provided inside the housing 12 to the subject. In Figure 1 the example shown, the light source is covered by a covering member 26A of 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 the light from a light source 14A provided inside the indicator 14 is emitted to the outside. The indicator 14 can notify information of the camera 10 by emitting light. For example, the indicator 14 can emit light according to the operation state of the camera 10. The indicator 14 is an example of the "light emitting part" related to the technology of the present utility model.

[0046] For example, when the camera 10 has a communication function with the outside, during the communication between the camera 10 and the outside, the indicator 14 emits light at a preset light emission interval and light emission color. In Figure 1 the example shown, an example of wireless communication between the smartphone 100 and the camera 10 is shown. 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 obtained by the camera 10 is sent to the smartphone 100, and the user can confirm the captured image IM with the smartphone 100.

[0048] In addition, here, as an example of the communication between the camera 10 and the outside, a form in which data of the captured image IM is transmitted to the smartphone 100 has been described, but this is only one example, and it may also be a mode in which data of the captured image IM is transmitted to an external printing device. And, for example, it may also be a mode in which software (for example, a control program of the camera 10) is downloaded in the camera 10.

[0049] And here, as information of the camera 10 notified by the indicator 14, the state of communication between the camera 10 and the outside has been given as an example, but this is only one example. For example, the indicator 14 may also notify the occurrence of a failure in the camera 10, a software update in the camera 10, etc. as the operation 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] And, through holes may also be formed at positions corresponding to the light source on the outer shell of the indicator 14. As a result, the light emitted from the light source is easily emitted to the outside through the through holes. As a result, it is easy to visually recognize the light emission of the indicator 14 from the outside.

[0052] And, 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 in the left - right direction ( Figure 1 the X direction shown). The power of the camera 10 can be turned on by pressing the power switch 15 several times (for example, 3 times). And the power of the camera 10 can be turned off by long - pressing the power switch 15 for several seconds (for example, 3 seconds).

[0053] And, a lower surface 12C is formed at the lower part of the housing 12. At least a part of the region including the center of the lower surface 12C is composed of a flat surface. As a result, the camera 10 can be placed on a tabletop or the like. Here, the flat surface includes a complete flat surface and a surface having a flatness sufficient to place the housing 12.

[0054] And, as an example, as Figure 2 shown, in the case where the side of the housing 12 opposite to the front surface 12A is used as the back surface 12B (that is, in the case where the side opposite to the front surface 12A in the optical axis direction of the photographic lens 20 is used as the back surface 12B), a shutter button 28 is provided on the back surface 12B. The shutter button 28 is configured to be pressable toward the front surface 12A side. As described above, by the user pressing the shutter button 28, the camera 10 captures a subject.

[0055] In general digital cameras, in many cases, a display unit (e.g., a liquid crystal display, etc.) for confirming the subject image is provided on the back surface. On the other hand, in the present embodiment, a display unit for confirming the subject image is not provided on the back surface 12B of the camera 10. Additionally, 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 of course be provided on the back surface 12B.

[0056] Moreover, a receiving unit 29 is provided on the back surface 12B of the housing 12. The receiving unit 29 is a terminal for receiving an electrical connection with an external device. The receiving unit 29 is, for example, a USB (Universal Serial Bus) terminal. Through the receiving unit 29, the battery of the camera 10 is charged, 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 general digital cameras. 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 the "camera system" related to the technology of the present utility model.

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

[0059] The accessory 50 includes a frame portion 52, a mounting portion 54, and a pair of cord mounting portions 56A, 56B. The frame portion 52 is a frame-shaped part that functions as a frame defining a viewing field when the accessory 50 functions as a viewfinder. The mounting portion 54 is a part for mounting the accessory 50 on the housing 12 of the camera 10. In Figure 2 the example shown, an example where the frame portion 52 is a circular ring-shaped frame is shown.

[0060] The pair of cord mounting portions 56A, 56B are parts for mounting the cord S on the accessory 50. In Figure 2 the example shown, the other end of the cord S is mounted on the cord mounting portion 56A provided on the side surface of the accessory 50.

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

[0062] As an example, as Figure 3 shown, the frame portion 52 has a first protrusion 52A and a second protrusion 52B on the upper surface side. When the fitting 50 functions as a mounting table 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 an example of the "multiple support protrusions" related to the technology of the present utility model.

[0063] Furthermore, the frame portion 52 has a first leg portion 52C and a second leg portion 52D on the lower surface side. When the fitting 50 functions as a mounting table, the first leg portion 52C and the second leg portion 52D abut against the installation surface of the fitting 50.

[0064] The mounting portion 54 has a through hole 54A, a first mounting guide portion 54B, and a second mounting guide portion 54C. The through hole 54A penetrates through the inside of the frame of the frame portion 52 and the mounting portion 54. That is, when observing the fitting 50 from the side of the mounting portion 54, the inside of the frame portion 52 can be visually recognized. The mounting portion 54 is an example of the "mounting portion" related to the technology of the present utility model, the frame portion 52 is an example of the "frame" related to the technology of the present utility model, and the through hole 54A is an example of the "through hole" related to the technology of the present utility model.

[0065] The first mounting guide portion 54B and the second mounting guide portion 54C are wall-shaped portions protruding from the end of the mounting portion 54. When the fitting 50 is mounted on the indicator 14, the first mounting guide portion 54B and the second mounting guide portion 54C guide the mounting. Moreover, the first mounting guide portion 54B and the second mounting guide portion 54C hold the indicator 14 from the side in the state where the fitting 50 is mounted on the indicator 14.

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

[0067] As an example, as Figure 4 shown, the fitting 50 is mounted on the camera 10. The fitting 50 is mounted on the indicator 14 of the camera 10 via the mounting portion 54. Specifically, the fitting 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 of the indicator 14. Thus, the fitting 50 is mounted on the indicator 14.

[0068] If the indicator 14 emits light in this state, the light emitted upward from the light emitted by the indicator 14 passes through the through-hole 54A of the mounting portion 54. Then, a part of the light passing through the through-hole 54A irradiates the inner side of the frame portion 52 of the accessory 50. For example, the inner region U of the frame portion 52 is irradiated with the light emitted from the indicator 14. In this way, the accessory 50 can irradiate the inner side of the frame portion 52 with the light emitted from the indicator 14.

[0069] As an example, as Figure 5 shown, the light emitted from the indicator 14 irradiates the inner side of the frame portion 52 of the accessory 50, and thus the light is reflected inside the frame portion 52. A part of the reflected light travels in the direction toward the user's eye E. As a result, the user can visually recognize the light emitted from the indicator 14.

[0070] Next, an example of the usage method of the camera 10 according to the present embodiment will be described.

[0071] As an example, as Figure 6 shown, the user holds the camera 10 by sandwiching the housing 12 from the front and back with fingers. Specifically, the index finger F1 and the middle finger F2 abut from the front 12A side of the housing 12 toward the back 12B side, and further the thumb F3 abuts from the back 12B side toward the front 12A side. On the front 12A of the housing 12, the opening 16 is sandwiched by the index finger F1 and the middle finger F2. In particular, the middle finger F2 abuts against the front 12A so as to support the opening 16 from below. On the other hand, on the back 12B, the user makes the thumb F3 abut against the shutter button 28.

[0072] And, as another way of holding the camera 10, the middle finger F2 may abut against the right side of the opening 16, and further the index finger F1 may abut against the left side of the opening 16. And, the user may also hold the camera 10 by sandwiching the housing 12 from above and below with fingers. Moreover, the camera 10 can of course also be held or operated by the user's both hands.

[0073] The accessory 50 has a function as a viewfinder in a state of being mounted on the camera 10. For example, when the user observes the viewfinder, the frame portion 52 of the accessory 50 serves as a reference for confirming the shooting range. Here, since no optical element such as a lens is provided in the frame portion 52 of the accessory 50, the frame portion 52 functions as a simple viewfinder (so-called sports viewfinder).

[0074] The fact that the frame portion 52 functions as a simple viewfinder means that, as Figure 6 shown, when used as a viewfinder, the user visually recognizes the subject through the frame that serves as a reference for confirming the shooting range, and has a function of confirming the shooting range by obtaining the direction of the camera 10 toward the subject and the range of the periphery of the subject that is introduced.

[0075] Further, the accessory 50 can function not only as a simple viewfinder but also as a viewfinder having an optical system such as a real-image viewfinder or a virtual-image viewfinder. In this case, various optical elements are provided in the frame portion 52 of the accessory 50.

[0076] Further, when the accessory 50 functions as a viewfinder, in a state where the user observes the viewfinder, the indicator 14 is disposed at a position where it can be visually recognized by the user. The position where the user can visually recognize the indicator 14 is set to a position where the distance L between the user's eye E and the accessory 50 as the viewfinder is appropriate. When observing the viewfinder at this position, the field of view ER inside the frame portion 52 corresponds to the imaging range IR of the camera 10. That is, the field of view ER coincides with the imaging range IR. In addition, coincidence includes a case of complete coincidence and also includes an error within an allowable range in the technical field to which the technology of the present invention belongs. Thus, when the user uses the viewfinder, the exposed portion of the indicator 14 is visually recognized by the user, and thereby the indicator 14 becomes a reference indicating the correspondence between the field of view of the subject observed from the viewfinder and the imaging range.

[0077] Then, after observing the viewfinder to confirm the imaging range, the user presses the shutter button 28 (refer to the arrow in Figure 6 ). Thereby, shooting based on the camera 10 is performed.

[0078] Further, as an example, as shown in Figure 7 and Figure 8 , the accessory 50 also functions as a mounting table on which the camera 10 can be mounted. In a state where the accessory 50 is provided on the installation 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 surface 12A side of the camera 10, and the frame portion 52 of the accessory 50 is located on the back surface 12B side of the camera 10. Moreover, the size of the circular frame of the frame portion 52 can hold the periphery of the lower surface 12C of the housing 12 of the camera 10. Further, 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 become support points for supporting the camera. Thereby, it is possible to prevent the camera 10 from detaching from the mounting table and being supported in an unstable state.

[0079] Moreover, in a state where the camera 10 is placed on the accessory 50 that functions as a mounting table, the optical axis K is upward with respect to the horizontal direction. That is, by placing the camera 10 on the mounting table, an elevation angle is given. Here, the height of the frame portion 52 from the setting surface G varies along the circumferential direction of the frame portion 52. Specifically, the height of the frame portion 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 portion 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 inclined in a direction away from the setting surface G toward the subject side of the optical axis K. Thus, the accessory 50 that functions as a mounting table can place the camera 10 in a posture in which the optical axis K of the camera 10 is inclined with respect to the horizontal direction.

[0080] As an example, as Figure 9 shown, the accessory 50 that functions as a mounting table has a shape capable of adjusting the inclination angle of the optical axis K with respect to the horizontal direction. That is, by the user rotating the camera 10 in a direction in which the elevation angle with respect to the accessory 50 is changed, the inclination angle is adjusted. Specifically, when the accessory 50 is viewed from the side, a continuous inclined surface extends 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 height of 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 with respect to the horizontal direction.

[0081] In Figure 9 the example shown, an example is shown in which the user tilts the camera 10 upward. That is, the camera 10 moves in a direction in which the optical axis K1 of the camera 10 is adjusted to the optical axis K2. And, the inclination angle θ1 with respect to the line HZ along the horizontal direction before adjustment is changed to the inclination angle θ2 after adjustment. Thus, the optical axis K of the camera 10 can be adjusted with respect 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. The accessory 50 functions as a viewfinder for confirming the shooting range of the camera 10 in a state of being mounted on the camera 10. Then, the light emitted from the indicator 14 can irradiate the inside of the frame of the viewfinder. Thus, compared with an accessory having the function of 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 emission based on the indicator 14.

[0083] Moreover, for example, compared with a structure in which the camera and the viewfinder are always integrated, since the accessory 50 mounted on the camera 10 functions as a viewfinder, miniaturization of the camera 10 can be achieved.

[0084] In a conventionally known accessory viewfinder, a light-emitting portion is provided outside the frame of the viewfinder. Therefore, there is a drawback that even in a bright environment such as a hot summer day, it is difficult to visually recognize the light emission even if the light emission amount is increased, and it is also difficult to confirm the light emission in a usage mode where the eyes are close to the eyepiece portion or in the case of glasses users. Therefore, due to the above configuration, the light emission irradiates inside the frame of the accessory viewfinder, so it is easy for the user to visually recognize the light emission from the light-emitting portion.

[0085] Moreover, in the camera system 1 according to the present embodiment, a through-hole 54A is formed in the mounting portion 54 of the accessory 50 for the camera 10. Then, the light from the indicator 14 passes through the through-hole 54A, enabling the light from the indicator 14 to irradiate the inside of the frame portion 52. Thus, compared with the case where a light guide member is provided on the accessory 50, it is easier for the user to visually recognize the light emission from the indicator 14 through a simplified structure.

[0086] Moreover, 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 shooting 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 of the viewfinder can be realized with a simple structure compared with the case where the viewfinder has optical elements such as a lens.

[0087] Moreover, if an optical element is provided in the frame portion 52, the light from the indicator 14 is deflected or diffracted by the optical element, so it may be difficult for the user to visually recognize the light emission from the indicator 14. In this structure, since the accessory 50 functions as a simple viewfinder without a lens, it is easy for the user to visually recognize the light from the indicator 14.

[0088] Moreover, 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 portion for carrying the camera 10 or as a mounting table on which the camera 10 can be placed. Thus, even when the accessory 50 is not mounted, the other functions of the accessory 50 can be utilized, so the usability of the accessory 50 is improved compared with an accessory 50 having only a single function.

[0089] Moreover, 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 placed. Thus, compared with the case where the camera 10 is directly placed on the placement surface G without passing through a mounting table, the camera 10 can be stably placed. This structure is effective, for example, when the camera 10 is used as a fixed-point camera.

[0090] Also, in the camera system 1 according to the present embodiment, 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 inclined with respect to the horizontal direction. Thus, by inclining the optical axis K of the camera 10 with respect to the horizontal direction, the imaging range of the camera 10 can be changed, and furthermore, the posture in which the camera 10 is inclined can be stably maintained. For example, by mounting the camera 10 in a state where the optical axis K of the camera 10 is inclined in a direction away from the setting surface G, a subject (e.g., a person) required by the user can be included in the imaging range more.

[0091] Also, in the camera system 1 according to the present embodiment, the accessory 50 that functions as a mounting table has a shape capable of adjusting the inclination angle θ of the optical axis K with respect to the horizontal direction. Thus, since the inclination angle of the camera 10 can be adjusted, shooting can be performed at the inclination angle required by the user.

[0092] Also, in the camera system 1 according to the present embodiment, in the accessory 50 that functions as a mounting table, the inclination angle can be adjusted by the height of the frame portion 52 from the setting surface G being different in the circumferential direction of the frame portion 52. Thus, since the inclination angle of the camera 10 can be adjusted, shooting can be performed at the inclination angle required by the user.

[0093] Also, 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 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 mounting table. The first protrusion 52A and the second protrusion 52B are arranged on the frame portion 52. Thus, since the first protrusion 52A and the second protrusion 52B abut against the lower portion of the camera 10 to support it, the camera 10 mounted on the accessory 50 that functions as a mounting table is stably supported.

[0094] Also, 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 notifies that the camera 10 is in communication by emitting light. When the camera 10 communicates with an external device, it is sometimes not suitable for shooting. By visually recognizing the inside of the frame portion 52 of the accessory 50 that functions as a viewfinder, the user can grasp whether the camera 10 is in a state suitable for shooting.

[0095] Further, in the camera system 1 according to the present embodiment, in a state where the user observes the viewfinder attached to the camera 10, the indicator 14 is disposed at a position where the light emitted from the indicator 14 can be visually recognized by the user. When using the viewfinder, since the indicator 14 can be visually recognized by the user, shooting within the shooting range desired by the user can be achieved. That is, when using the viewfinder, the indicator 14 serves as a reference indicating the correspondence between the field of view observed from the viewfinder and the shooting range, so that shooting within the shooting range desired by the user can be achieved.

[0096] (First Modified Example)

[0097] In the above embodiment, an example in which the light from the indicator 14 is irradiated onto the inner side of the frame portion 52 through the through hole 54A has been described, but the technology of the present utility model is not limited thereto. In this first modified example, a part of the fitting 50 is formed of a light-transmissive material.

[0098] As an example, as Figure 10 shown, a light-transmissive portion 58 is formed in the mounting portion 54 of the fitting 50. The light-transmissive portion 58 transmits the light emitted from the indicator 14. The light-transmissive portion 58 is formed of a material that is transparent to visible light, that is, a light-transmissive material. The light-transmissive material is, for example, acrylic resin or the like.

[0099] In Figure 10 the example shown, the light-transmissive portion 58 is formed between the mounting portion 54 and the frame portion 52. The light emitted from the indicator 14 is transmitted through the light-transmissive portion 58, and a part of it irradiates the inner side of the frame portion 52 of the fitting 50. For example, the inner region U of the frame portion 52 is irradiated with the light emitted from the indicator 14. In this way, the fitting 50 can irradiate the inner side of the frame portion 52 with the light emitted from the indicator 14.

[0100] As described above, in this first modified example, a part of the fitting 50 is formed of a light-transmissive material, and the light from the indicator 14 can irradiate the inner side of the frame portion 52. Thereby, 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 based on the indicator 14.

[0101] Further, in this first modified example, not only the inner side of the frame portion 52, but also the light is scattered in the light-transmissive portion 58, so that a part of the fitting 50 itself also emits light, and thus the user can easily visually recognize the light emission of the indicator 14.

[0102] In addition, in this first modified example, an example in which a part of the fitting 50 is formed of a light-transmissive material has been described, but the technology of the present utility model is not limited thereto. For example, the entire fitting 50 may be formed of a light-transmissive material.

[0103] (Second Modified Example)

[0104] In the above-described embodiment, an example of the form in which the light from the indicator 14 is irradiated onto the inner side of the frame portion 52 through the through hole 54A has been described, but the technology of the present utility model is not limited thereto. In this second modification, a light guide member 60 is provided in the fitting 50.

[0105] As an example, as Figure 11 shown, the fitting 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 inner side of the frame portion 52 by allowing the light from the indicator 14 to propagate inside. In Figure 11 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 reflecting surface 62 and further reflected by the second reflecting surface 64. Then, the light reflected by the second reflecting surface 64 is emitted toward the inner side of the frame portion 52.

[0106] A part of the light emitted from the indicator 14 irradiates the inner side of the frame portion 52 of the fitting 50 via the light guide member 60. For example, the inner region U of the frame portion 52 is irradiated with the light emitted from the indicator 14. In this way, the fitting 50 can irradiate the inner side of the frame portion 52 with the light emitted from the indicator 14.

[0107] As described above, in this second modification, a light guide member 60 is provided in the fitting 50. The light from the indicator 14 can irradiate the inner side of the frame portion 52 via the light guide member 60. As a result, the inside of the viewfinder frame can be illuminated with the light from the indicator 14, so that the user can easily visually recognize the light emission based on the indicator 14.

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

[0109] In addition, in this second modification, an example of using the prism 61 as the light guide member 60 has been described, but the technology of the present utility model is not limited thereto. As an example, as Figure 12 shown, a fiber 66 is used as the light guide member 60. One end portion of the fiber 66 is disposed at a position facing the light source 14A of the indicator 14, and the other end portion of the fiber 66 is disposed inside the frame portion 52. The light from the indicator 14 travels inside the fiber 66 and is emitted toward the inner side of the frame portion 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 mistakenly operated by the user, the camera 10 may be powered off without the user's intention, such as during use or communication with the outside. Therefore, a switch cover is sometimes required to prevent mistaken operation of the power switch 15.

[0113] A conventional switch cover consists of a rectangular box-shaped housing and a cover that opens and closes an opening defined by the housing, viewed from above. This switch cover is mounted on the camera so that the switch is housed within the box-shaped housing. The opening is large enough to accommodate a user's finger. When the switch cover is mounted on the camera, the opening is closed by the cover when the switch is not being operated. However, when the user operates the switch, the cover opens, allowing the user to insert their finger into the opening and press the switch. This prevents user error when the cover is closed. However, this structure requires a cover opening and closing mechanism (e.g., a hinge mechanism) to be incorporated into the switch cover. This can sometimes limit the design freedom of the switch cover, such as its shape and size. In particular, when the camera 10, as in this embodiment, has a small housing and a distinctive design, shape and size restrictions can make it difficult to adapt the switch cover design to the camera 10 itself.

[0114] Another previously known technology related to switch covers is a cover made of a soft resin that covers the entire switch. In this case, when a user presses the switch, if an external force greater than a specified value is applied by the user's finger, the switch cover elastically deforms, allowing the switch to be pressed directly through the cover. Therefore, under weak forces such as light contact, the switch cover will not deform or will deform only slightly, thereby preventing user errors. However, this switch cover that covers the entire switch has the following problem. Specifically, some switches in a camera illuminate depending on the operating status. When a switch cover that covers the entire switch is added to a switch cover with an illuminating function, the color of the switch cover needs to be made of a light-transmitting material to ensure visual recognition of the light, resulting in color restrictions. As with the above-mentioned prior art, the color restrictions limit 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 the function of a switch cover. As an example, Figure 13As shown, the accessory 50 is set in a state of being installed on the indicator 14. Consider the following situation: in this state, the user's finger F accidentally approaches the power switch 15 from above the indicator 14.

[0116] In this case, as an example, as Figure 14 shown, the power switch 15 is provided in a state of protruding from one surface of the camera 10 (here, the upper surface 14B of the indicator 14). And, the accessory 50 includes a restricting portion 59. In a state where the accessory 50 is installed on the camera 10, the restricting portion 59 restricts contact with the power switch 15. The restricting portion 59 is an example of the "restricting portion" involved in the technology of the present utility model.

[0117] The restricting portion 59 is disposed at at least a part of the periphery of the power switch 15. In Figure 14 the example shown, the restricting portion 59 is set as a peripheral wall 59A surrounding the periphery of the power switch 15. The peripheral wall 59A is an example of the "peripheral wall" involved in the technology of the present utility model. In a state where the accessory 50 is installed on 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. Thus, if the finger F attempts to approach the power switch 15, first the finger F contacts the upper part of the restricting portion 59 and contact with the power switch 15 is inhibited. As a result, accidental contact of the finger F or the like with the power switch 15 can be inhibited.

[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 inhibit contact with the power switch 15 even when pressed with the finger F. That is, even when the restricting portion 59 is pressed with the finger F, the opening area 59B is separated from the power switch 15 by a specified distance or more.

[0119] As an example, as Figure 15 shown, when looking down at the power switch 15 from the top portion 59A1 in the height direction of the restricting portion 59, an opening area 59B is formed in the restricting portion 59. And, the opening area 59B is formed to overlap at least a part of the power switch 15. The opening area 59B transmits the light emitted by the power switch 15. The top portion 59A1 is an example of the "top portion" involved in the technology of the present utility model, and the opening area 59B is an example of the "opening area" involved in the technology of the present utility model.

[0120] As described above, the peripheral wall 59A surrounds the power switch 15. And, in Figure 15 the example shown, the opening area 59B is one opening 59B1 defined by the peripheral wall 59A. The opening 59B1 is an example of the "opening" involved in the technology of the present utility model.

[0121] Further, the size of the opening area 59B is set to be able to prevent the finger F from entering 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 the direction orthogonal to the long side direction of the finger when observing the finger from the back of the hand side), and particularly refers to the average width of the root of the index finger nail (the portion of the nail closest to the first joint side). Moreover, the size that can prevent the finger F from entering refers to a size equal to or less than this average value.

[0122] Here, the opening 59B1 is set to be elliptical in a top view. The distance t in the minor axis direction of the opening 59B1 is set to be a distance that can prevent the finger F from contacting the power switch 15 and can ensure the light amount of the light from the indicator 14. For example, the distance t is 10 mm or less.

[0123] In addition, here, an example configuration where the opening 59B1 is elliptical has been described, but the technology of the present invention is not limited thereto. The opening 59B1 may also be oblong. Moreover, the opening 59B1 may also be rectangular. In this case, the distance t is the distance in the short side direction of the rectangle.

[0124] Moreover, the opening 59B1 is open to the outside. In other words, the inside of the opening 59B1 is not filled with resin, nor is a cover installed on the opening 59B1.

[0125] Further, in a state where the fitting 50 is attached to the indicator 14, a member including an opposing portion that opposes the opening area 59B is provided on an extension line L1 of a straight line extending along the height direction of the restricting portion 59 from the power switch 15 toward the opening 59B1.

[0126] In Figure 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 a circular ring shape. The upper arc portion 52E of the circular ring-shaped frame portion 52 is provided at a position opposing the opening 59B1. The frame portion 52 is in a circular ring shape with the direction along the straight line as the radial direction. The frame portion 52 is an example of the "member" related to the technology of the present invention, and the upper arc portion 52E is an example of the "opposing portion" related to the technology of the present invention.

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

[0128] According to the accessory 50 according to this embodiment, a power switch 15 is provided on the camera 10, and the accessory 50 is mounted on the camera 10. Further, a restricting portion 59 is provided on the accessory 50. The restricting portion 59 has a height h1 that is higher than the protruding amount h2 of the power switch 15. Moreover, an opening 59B1 that overlaps a part of the power switch 15 in a plan view is provided in the restricting portion 59. The size of the opening 59B1 is set to allow the light of the power switch 15 to transmit therethrough and to prevent a user's finger from entering.

[0129] Thus, in a state where the accessory 50 is mounted on the indicator 14, even if a user's finger F accidentally approaches the power switch 15, the finger F will first contact the restricting portion 59, so that contact with the power switch 15 can be suppressed. That is, it is not necessary to provide a cover on the opening 59B1, and the degree of freedom in the design (e.g., shape and size) of the accessory 50 can be increased. For example, a design of the accessory 50 that matches the camera 10 can be achieved. Further, since the 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 can be achieved. For example, a material other than a transparent material can be adopted.

[0130] Moreover, even when the restricting portion 59 is pressed by the finger F, the position of the top portion 59A1 is separated from the power switch 15 by a predetermined distance or more. Thereby, accidental contact of the finger F or the like with the power switch 15 can be suppressed. For example, sometimes even in the case of an unintentional operation, the power switch 15 may be pressed through a cover by a pressing force. In this structure, even when pressed by the finger F, the distance between the power switch 15 and the top portion 59A1 of the restricting portion 59 can be sufficiently ensured by the restricting portion 59, so that accidental contact of the finger F can be further suppressed.

[0131] According to the accessory 50 according to this embodiment, the restricting portion 59 is a peripheral wall 59A. The opening 59B1 is defined by the peripheral wall 59A. Thereby, the force received from the finger F approaching the power switch 15 can be dispersed and supported by the peripheral wall 59A, and the approach from a plurality of directions such as front, rear, left, and right can also be suppressed. As a result, the approach of the finger F to the power switch 15 can be suppressed.

[0132] According to 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 contacts the power switch 15, since it is generally difficult for a human finger to pass through a 10-mm gap to contact the power switch 15, accidental contact of the finger F with the power switch 15 can be suppressed.

[0133] Moreover, according to the fitting 50 according to the present embodiment, in a state where the fitting 50 is installed, a frame portion 52 is provided above the restricting portion 59. The arc portion 52E on the upper side of the frame portion 52 is disposed at a position opposed to the opening region 59B. Thereby, a posture of the finger F such as inserting the nail of the finger F into the opening region 59B can be restricted, and the finger F can be prevented from accidentally contacting the power switch 15.

[0134] Moreover, according to the fitting 50 according to the present embodiment, the frame portion 52 is an annular member including the upper arc portion 52E and having the extension line L1 as the radial direction. Thereby, compared with the case where a member for restricting the posture of the finger F or the like is additionally provided at a position opposed to the opening region 59B, simplification of the structure of the fitting 50 can be achieved.

[0135] In addition, in the above-described embodiment, an example of a form in which the opening 59B1 is formed as the opening region 59B has been described, but the technology of the present invention is not limited thereto. In this modification, a plurality of openings 59B 2 are formed as the opening region 59B. The plurality of openings 59B 2 are an example of the "plurality of openings" according to the technology of the present invention.

[0136] As an example, as Figure 16 shown, a ceiling portion 59A 2 is formed on the top portion 59A 1 of the restricting portion 59. The ceiling portion 59A 2 covers the power switch 15. A plurality of openings 59B 2 are formed in the ceiling portion 59A 2 as the opening region 59B. In Figure 16 the example shown, four openings 59B 2 are formed. The ceiling portion 59A 2 is an example of the "ceiling portion" according to the technology of the present invention.

[0137] The plurality of openings 59B 2 transmit light from the power switch 15. Moreover, the size of each of the plurality of openings 59B 2 is set to be able to prevent the finger F from entering. In Figure 16 the example shown, each of the plurality of openings 59B 2 is circular and has a diameter of 10 mm or less.

[0138] As described above, in this modification, the ceiling portion 59A 2 is formed in the restricting portion 59, and a plurality of openings 59B 2 are formed in the ceiling portion 59A 2. Thereby, in a state where the fitting 50 is installed on the indicator 14, even if the user's finger F accidentally approaches the power switch 15, since it is covered by the ceiling portion 59A 2, contact between the user's finger F and the power switch 15 can be further suppressed. Moreover, since a plurality of openings 59B 2 are formed, the amount of light from the power switch 15 can be ensured.

[0139] In addition, in the above-described embodiments, a form example in which a power switch 15 is provided on the indicator 14 has been described, but the technology of the present invention is not limited thereto. Other switches and / or operation dials or the like may be provided on the indicator 14 instead of or together with the power switch 15.

[0140] Moreover, in the above-described embodiments, an example of the restricting portion 59 is the peripheral wall 59A, but the technology of the present invention is not limited thereto. The restricting portion 59 only needs to be able to inhibit contact between the finger F and the power switch 15, and may be a cylindrical body or a frustum-shaped body formed around the power switch 15. Also, the restricting portion 59 may be an aggregate of a plurality of columns arranged around the power switch 15.

[0141] Furthermore, in the above-described embodiments, a form example in which an oval opening 59B1 is formed in the restricting portion 59 has been 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] Also, the object to which the fitting 50 serving as a switch cover is attached is not limited to the camera 10. For example, it may be a small electronic device or a toy.

[0143] In addition, in the above-described embodiments, a form example in which the fitting 50 and the camera 10 are connected by a cord S has been described, but the technology of the present invention is not limited thereto. For example, they may be connected by a component other than the cord S (e.g., a chain). Also, the fitting 50 and the camera 10 do not need to be connected, and the fitting 50 may be prepared according to the scene of the fitting 50 as needed.

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

[0145] In addition, in the above-described embodiments, a form example in which the frame portion 52 is a circular ring-shaped frame has been described, 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-described embodiments, a form example in which the housing 12 has a shape with substantially oval rounded corners has been described, but the technology of the present invention is not limited thereto. The housing 12 may be spherical, spindle-shaped, or quadrilateral.

[0147] Moreover, in each of the above-described embodiments, a form example in which the indicator 14 is provided on the upper portion of the housing 12 of the camera 10 has been described, but the technology of the present invention is not limited thereto. The arrangement of the indicator 14 is not particularly limited. For example, it may be provided on the right side surface or the left side surface of the housing 12.

[0148] Moreover, in each of the above-described embodiments, a case where the shutter button 28 is a physical button has been described, but the technology of the present invention is not limited thereto. For example, the shutter button 28 may also be in a form displayed on a touch screen display.

[0149] Moreover, in each of the above-described embodiments, a form example in which 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 has been described, but the technology of the present invention is not limited thereto. As long as the accessory 50 can be attached to and detached from the indicator 14 via the attachment portion 54.

[0150] For example, it may also be the following method: The attachment portion 54 is attached by fitting a protrusion provided on the attachment 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 the engagement feeling at the time of fitting.

[0151] Moreover, it may be the following method: When the accessory 50 is attached to the indicator 14, after attaching it to the indicator 14 from above, an operation of rotating the accessory 50 in a direction orthogonal to the attachment direction (i.e., a twisting operation) is performed, so that the accessory 50 is fixed to the indicator 14. And it may also be the following method: For example, a clamping mechanism is provided in the attachment portion 54, and the accessory 50 is attached by gripping the indicator 14 with the claws of the clamping mechanism.

[0152] The description content and the illustrated content shown above are detailed descriptions of parts related to the technology of the present invention, and are only an example of the technology of the present invention.
