[0046] Hereinafter, an example of an embodiment of the binoculars 10 according to the present invention will be described with reference to the accompanying drawings.

[0047] As an example, such as Figures 1 to 6 As shown, one embodiment of the present invention relates to a binoculars 10, for example, an optically anti-vibration binoculars with anti-vibration function. Here, as an example of binoculars 10, an optically anti-vibration binoculars is given, but this is only one example, and binoculars 10 can be binoculars with any function.

[0048] As an example, the binoculars 10 have left-right, up-down, and front-back directions. These directions are orthogonal to each other. The X-direction represents the left-right direction, the Y-direction represents the front-back direction, and the Z-direction represents the up-down direction. L The side indicates the left side of binoculars 10, X R The side indicates the right side of binoculars 10. Y F The side indicates the front side of the binoculars 10, Y R The side indicates the rear side of the binoculars 10. Z UThe side indicates the upper side of the binoculars 10, Z. L The side refers to the lower side of the binoculars 10. The binoculars 10 have a pair of optical axes OA. The front-back direction of the binoculars 10 is the direction along each optical axis OA of the binoculars 10.

[0049] The binoculars 10 include a main body 12, an objective lens optics 14, and an eyepiece optics 16. The objective lens optics 14 is located at the front end of the main body 12, and the eyepiece optics 16 is located at the rear end of the main body 12. The main body 12 is the portion located between the objective lens optics 14 and the eyepiece optics 16 in the binoculars 10, constituting the main body of the binoculars 10.

[0050] The objective lens optics unit 14 is an optical device having an objective lens unit 18A and an objective lens unit 18B. The objective lens units 18A and 18B are arranged in the X direction. The objective lens unit 18A is located on the left side of the objective lens optics unit 14, and the objective lens unit 18B is located on the right side of the objective lens optics unit 14. Hereinafter, without distinguishing between the objective lens units 18A and 18B, the objective lens units 18A and 18B will be referred to as objective lens units 18. Each objective lens unit 18 has an objective lens 20.

[0051] The eyepiece optics 16 is an optical device having eyepiece lens sections 24A and 24B. Eyepiece lens sections 24A and 24B are arranged in the X direction. Eyepiece lens section 24A is located on the left side of the eyepiece optics 16, and eyepiece lens section 24B is located on the right side of the eyepiece optics 16. Hereinafter, without distinguishing between eyepiece lens sections 24A and 24B, eyepiece lens sections 24A and 24B will be referred to as eyepiece lens sections 24. Each eyepiece lens section 24 has an eyepiece lens 26, a lens barrel 28, and a protective member 30. The eyepiece lens 26 is disposed inside the lens barrel 28 and supported by the lens barrel 28. Each lens barrel 28 is connected to the main body 12. Each protective member 30 is, for example, a rubber ring, fixed to the rear end of the lens barrel 28. The eyepiece optics 16 is connected to the main body 12 via each lens barrel 28 and is supported by the main body 12.

[0052] A front cover 32 is provided on the objective lens optics section 14. The front cover 32 has a size and shape that covers the objective lens sections 18A and 18B from the front side of the objective lens optics section 14. A hinge 34 is provided at the lower end of the front cover 32. The front cover 32 is rotatably supported on the objective lens optics section 14 by the hinge 34, and can be displaced between a first position covering the objective lens optics section 14 and a second position exposing the objective lens optics section 14. In addition, a diopter adjustment ring 36 for adjusting the diopter of the binoculars 10 is provided on the lens barrel 28 of the eyepiece lens section 24B. Furthermore, a focus adjustment dial 38 for adjusting the focus is provided on the main body section 12.

[0053] The main body 12 has a first lens barrel portion 40, a second lens barrel portion 42, and a connecting portion 44. The first lens barrel portion 40 is located on the left side of the main body 12, and the second lens barrel portion 42 is located on the right side of the main body 12. The connecting portion 44 is located between the first lens barrel portion 40 and the second lens barrel portion 42, and connects the first lens barrel portion 40 and the second lens barrel portion 42.

[0054] The main body 12 has a frame 46. The frame 46 has a bottom surface 46A, a top surface 46B, a side surface 46C, and a side surface 46D. The bottom surface 46A is the lower surface of the main body 12, and the top surface 46B is the upper surface of the main body 12. The side surface 46C is the left side surface of the main body 12, and the side surface 46D is the right side surface of the main body 12.

[0055] As an example, such as Figure 7 As shown, the main body 12 includes a pair of optical systems 48 including a vibration damping mechanism and a drive power supply 50 for driving the vibration damping mechanism. One of the pair of optical systems 48 is disposed inside the first lens barrel 40, and the other of the pair of optical systems 48 is disposed inside the second lens barrel 42. As an example, the drive power supply 50 is housed in the second lens barrel 42. As an example, the drive power supply 50 has a plurality of batteries 52. As an example, the number of the plurality of batteries 52 is two. The plurality of batteries 52 are arranged in a vertical direction in the main body 12. The drive power supply 50 is disposed on the side 46D opposite to the pair of optical systems 48. Furthermore, the drive power supply 50 is disposed opposite to the recess 54 described later (see reference). Figures 8 to 10 The side 46D of the battery is provided with a battery cover 53 that covers multiple batteries 52.

[0056] As an example, such as Figures 8 to 10 As shown, a recess 54 is formed on the bottom surface 46A. The recess 54 is shaped to be recessed towards the top surface 46B. When viewed from below the main body 12, the recess 54 is quadrilateral. The recess 54 has: a first side surface 54A, formed in the bottom surface 46A as a first lens barrel portion 40; a second side surface 54B, formed in the bottom surface 46A as a second lens barrel portion 42; and a connecting surface 54C, formed in the bottom surface 46A as a connecting portion 44. The first side surface 54A and the second side surface 54B are curved surfaces, and the connecting surface 54C is a plane.

[0057] A first surface shape portion 56 with a three-dimensional shape is formed on the surface of the recess 54. On the other hand, a second surface shape portion 58 with a three-dimensional shape is formed on the surface of the top surface 46B (for example, see reference). Figure 6 The first surface shape portion 56 has a three-dimensional shape different from the second surface shape portion 58. This will be explained in detail below.

[0058] As an example, such as Figure 11As shown, the first surface shape portion 56 has a pattern shape with a repeating unique pattern (hereinafter referred to as the "first pattern"). The first pattern has a first shape portion 56A, a second shape portion 56B, and a third shape portion 56C. The first shape portion 56A extends in a first direction D1 that intersects the optical axis OA of the binoculars 10 (hereinafter referred to as the "optical axis direction D0"). As an example, the first direction D1 is a direction orthogonal to the optical axis direction D0. The second shape portion 56B extends in a second direction D2 that is inclined relative to the optical axis direction D0 and the first direction D1. The third shape portion 56C extends in a third direction D3 that is inclined relative to the optical axis direction D0, the first direction D1, and the second direction D2. The inclination angle of the second direction D2 relative to the first direction D1 is the same as the inclination angle of the third direction D3 relative to the first direction D1. The inclination angle is an acute angle. The cross-sectional shapes of the first shape part 56A, the second shape part 56B, and the third shape part 56C can be rectangular, semi-circular, or triangular.

[0059] The first surface shape portion 56 has a pattern shape in which the first pattern is repeatedly arranged in the first direction D1, the second direction D2, and the third direction D3. Furthermore, the first surface shape portion 56 can be understood as having a pattern shape in which the first pattern is repeatedly arranged in the first direction D1 and the second direction D2, or it can be understood as having a pattern shape in which the first pattern is repeatedly arranged in the first direction D1 and the third direction D3, or it can be understood as having a pattern shape in which the first pattern is repeatedly arranged in the second direction D2 and the third direction D3.

[0060] The first shape portion 56A, the second shape portion 56B, and the third shape portion 56C are separated from each other. Therefore, gaps are provided between each of the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C. The first shape portion 56A extends linearly along the first direction D1, the second shape portion 56B extends linearly along the second direction D2, and the third shape portion 56C extends linearly along the third direction D3. The first shape portion 56A, the second shape portion 56B, and the third shape portion 56C extend linearly along the first direction D1, the second direction D2, and the third direction D3 respectively, thereby forming a triangular shape. The triangular shape is, for example, an equilateral triangle. By having the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C, the first surface shape portion 56 has a shape that generates a gripping force when a gripping force is applied in the optical axis direction D0 and when a gripping force is applied in a direction intersecting the optical axis direction D0.

[0061] As an example, such as Figure 6As shown, the second surface shape portion 58 has a pattern of multiple protrusions 58A extending in the optical axis direction D0 arranged in a fourth direction D4 intersecting the optical axis direction D0. For example, the fourth direction D4 is orthogonal to the optical axis direction D0. Each protrusion 58A extends linearly along the optical axis direction D0. The cross-sectional shape of each protrusion 58A can be rectangular, semi-circular, or triangular. The second surface shape portion 58 has a shape that generates a gripping force when a gripping force is applied in the direction intersecting the optical axis direction D0 by having multiple protrusions 58A. Thus, the first surface shape portion 56 has a three-dimensional shape different from the second surface shape portion 58. The first surface shape portion 56 will be described in further detail below.

[0062] As an example, such as Figures 8 to 10 As shown, the first surface shape portion 56, in addition to the surface of the recess 54, also includes regions 46A1 and 46A2 on the bottom surface 46A that are adjacent to the recess 54 on both sides. For example, regions 46A1 and 46A2 include regions adjacent to the recess 54 on both sides in the left-right direction of the main body portion 12. Furthermore, region 46A1 includes the top 40A region on the bottom surface 46A side of the first lens barrel portion 40, and region 46A2 includes the top 42A region on the bottom surface 46A side of the second lens barrel portion 42. For example, region 46A1 includes the top 40A extending to the side surface 46C, and region 46A2 includes the top 42A extending to the side surface 46D. In addition, region 46A1 is a region that is closer to the recess 54 than the side 46C of the main body 12, and region 46A2 is a region that is closer to the recess 54 than the side 46D of the main body 12. Therefore, the first surface shape portion 56 is not formed on the side 46C and the side 46D.

[0063] A wall surface 60 is formed at the first end 54D in the optical axis direction of the recess 54 (reference). Figure 8 and Figure 10 The first end portion 54D is the objective lens side end portion of the recess 54 (i.e., the front end portion of the recess 54). A wall surface 60 is erected on the surface of the recess 54 and extends in both the left-right and up-down directions of the main body 12. The wall surface 60 is located between the central portion of the main body 12 in the optical axis direction D0 and the objective lens side end portion of the main body 12. The second end portion 54E in the optical axis direction of the recess 54 does not have a wall surface and opens towards the optical axis direction D0. The second end portion 54E is the end portion of the recess 54 on the side opposite to the objective lens side (i.e., the rear end portion of the recess 54).

[0064] As explained above, the binoculars 10 of this embodiment include a main body 12 having a bottom surface 46A and a top surface 46B. A recess 54 is formed on the bottom surface 46A that is recessed toward the top surface 46B. A first surface shape portion 56, which is three-dimensionally formed in the recess 54, is different from a second surface shape portion 58, which is three-dimensionally formed on the top surface 46B. Therefore, for example, compared to the case where the recess 54 has the same surface shape portion as the second surface shape portion 58, a stronger grip force can be generated, thus improving the grip performance of the main body 12.

[0065] Specifically, the first surface shape portion 56 has a pattern shape in which a first pattern is repeated. The first pattern has: a first shape portion 56A extending in a first direction D1 intersecting the optical axis direction D0; and a second shape portion 56B extending in a second direction D2 inclined relative to the optical axis direction D0 and the first direction D1. Therefore, when a gripping force is applied in the optical axis direction D0, the user's finger (e.g., thumb) engages in the first shape portion 56A, thereby generating a gripping force in the optical axis direction D0. Furthermore, when a gripping force is applied in a direction intersecting the optical axis direction D0, the user's finger engages in the second shape portion 56B, thereby generating a gripping force in the direction intersecting the optical axis direction D0.

[0066] Furthermore, the first surface shape portion 56 has a pattern shape in which the first pattern is repeated in the first direction D1 and the second direction D2. As a result, a gripping force can be generated throughout the area in which the first surface shape portion 56 is formed in the optical axis direction D0 and in the direction intersecting the optical axis direction D0.

[0067] Furthermore, the first shape portion 56A and the second shape portion 56B are separated from each other. Therefore, compared with the case where the first shape portion 56A and the second shape portion 56B are connected, the addition of edge portions in the first shape portion 56A and the second shape portion 56B can generate a stronger grip.

[0068] Furthermore, the first pattern has a third shape portion 56C extending in a third direction D3 that is inclined relative to the optical axis direction D0 and the first direction D1. Therefore, when a gripping force is applied in the direction intersecting the optical axis direction D0, the user's fingers will also be engaged in the third shape portion 56C, thereby generating a stronger gripping force in the direction intersecting the optical axis direction D0.

[0069] Furthermore, the first surface shape portion 56 has a pattern shape in which the first pattern is repeated in the first direction D1, the second direction D2, and the third direction D3. Therefore, compared to the case where only the first pattern is repeated in the first direction D1 and the second direction D2, a stronger gripping force can be generated throughout the area where the first surface shape portion 56 is formed, in the optical axis direction D0 and in the direction intersecting the optical axis direction D0.

[0070] Furthermore, the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C are separated from each other. Therefore, compared to the case where the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C are connected, the addition of edge portions in the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C results in a stronger grip.

[0071] Furthermore, the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C form a triangular shape. As a result, compared to the case where the first surface shape portion 56 has a pattern shape in which the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C are arranged irregularly, the design of the bottom surface 46A of the first surface shape portion 56 can be improved.

[0072] Furthermore, the second surface shape portion 58 has a pattern of multiple protrusions 58A extending in the optical axis direction D0 arranged in a fourth direction D4 intersecting the optical axis direction D0. Thus, compared to the case where the second surface shape portion 58 is not formed on the top surface 46B, when a gripping force is applied in the direction intersecting the optical axis direction D0, the user's fingers (e.g., index finger, middle finger, ring finger, and little finger) are engaged on the protrusions 58A, thereby generating a gripping force in the direction intersecting the optical axis direction D0.

[0073] Furthermore, the first surface shape portion 56 is also formed in regions 46A1 and 46A2 adjacent to the recess 54 in the bottom surface 46A. As a result, compared to the case where the range of the first surface shape portion 56 is contained within the recess 54, the range of the first surface shape portion 56 is expanded, thus enabling the generation of gripping force over a wider range.

[0074] Furthermore, regions 46A1 and 46A2 include regions adjacent to the recess 54 in the left-right direction of the main body 12. This expands the range capable of generating gripping force to the left-right direction of the main body 12.

[0075] Furthermore, the main body 12 includes a first lens barrel portion 40 and a second lens barrel portion 42 arranged in the left-right direction. Region 46A1 includes the region of the top 40A on the bottom surface 46A side of the first lens barrel portion 40, and region 46A2 includes the region of the top 42A on the bottom surface 46A side of the second lens barrel portion 42. As a result, in at least one of the top 40A on the bottom surface 46A side of the first lens barrel portion 40 and the top 42A on the bottom surface 46A side of the second lens barrel portion 42, the palmar surface of the user's finger (e.g., thumb) is engaged with the first surface shape portion 56, thus generating a stronger grip compared to the case where the first surface shape portion 56 is not formed in regions 46A1 and 46A2.

[0076] Furthermore, region 46A1 is the region further towards the recess 54 than the side surface 46C of the main body 12, and region 46A2 is the region further towards the recess 54 than the side surface 46D of the main body 12. Therefore, the first surface shape portion 56 is not formed on the side surfaces 46C and 46D of the main body 12, thus improving the design flexibility of the side surfaces 46C and 46D of the main body 12 compared to the case where the first surface shape portion 56 is formed on the side surfaces 46C and 46D.

[0077] Furthermore, a wall surface 60 is formed at the first end 54D in the optical axis direction D0 of the recess 54. As a result, compared with the case where the wall surface 60 is not formed at the first end 54D, it is possible to prevent the user from touching the object with their finger beyond the first end 54D.

[0078] Furthermore, the first end portion 54D is the objective lens side end portion within the recess 54. As a result, compared to the case where the wall surface 60 is not formed at the first end portion 54D, it is possible to suppress the user's finger from touching the objective lens optics 14.

[0079] Furthermore, the wall surface 60 is located between the central portion of the main body 12 in the optical axis direction D0 and the end portion of the main body 12 on the objective lens side (i.e., the front end portion of the main body 12). Thus, for example, compared to the case where the wall surface 60 is located between the central portion of the main body 12 in the optical axis direction D0 and the end portion of the main body 12 on the side opposite to the objective lens side (i.e., the rear end portion of the main body 12), the range of the recess 54 can be expanded, and consequently the range of the first surface shape portion 56 can be expanded, thereby increasing the degree of freedom of the user's finger position.

[0080] Furthermore, the second end portion 54E in the recess 54, in the direction of the optical axis D0, opens towards the direction of the optical axis D0. Thus, for example, compared to the case where a wall surface 60 is formed at the second end portion 54E, it is possible to prevent the user's finger from getting stuck on the second end portion 54E, thereby improving the practicality of the binoculars 10.

[0081] Furthermore, the main body 12 includes: a first lens barrel portion 40 and a second lens barrel portion 42, arranged in the left-right direction of the main body 12; and a connecting portion 44 connecting the first lens barrel portion 40 and the second lens barrel portion 42. The recess 54 has: a first side surface 54A formed in the bottom surface 46A of the first lens barrel portion 40; a second side surface 54B formed in the bottom surface 46A of the second lens barrel portion 42; and a connecting surface 54C formed in the bottom surface 46A of the connecting portion 44. Thus, for example, compared to the case where the recess 54 is only formed in the area of ​​the connecting surface 54C, the area of ​​the recess 54 can be expanded, thereby expanding the area of ​​the first surface shape portion 56, and thus generating a gripping force over a wider range.

[0082] Furthermore, the first side surface 54A and the second side surface 54B are curved surfaces. Therefore, compared to the case where the first side surface 54A and the second side surface 54B are formed by vertical surfaces perpendicular to the connecting surface 54C, the user's fingers contact the first side surface 54A and the second side surface 54B with equal pressure, thus improving both tactile feel and grip strength. Furthermore, the connecting surface 54C is a flat surface. Therefore, for example, compared to the case where the connecting surface 54C is a concave surface recessed towards the top surface 46B, it is possible to prevent the internal space of the main body 12 from narrowing.

[0083] Furthermore, the main body 12 includes an optical system 48, including a vibration damping mechanism, and a drive power supply 50 for driving the vibration damping mechanism. The drive power supply 50 is disposed on the side 46D of the main body 12 opposite to the optical system 48. This prevents interference between the drive power supply 50 and the optical system 48.

[0084] Furthermore, the drive power supply 50 is disposed on the side 46D opposite to the recess 54. As a result, interference between the drive power supply 50 and the recess 54 can be avoided while expanding the range of the recess 54, thereby expanding the range of the first surface shape portion 56, thus enabling the generation of gripping force over a wider range.

[0085] Furthermore, the first surface shape portion 56 has a shape that generates a gripping force when a gripping force is applied in the optical axis direction D0, and the second surface shape portion 58 has a shape that generates a gripping force when a gripping force is applied in a direction intersecting the optical axis direction D0. Thus, for example, compared to the case where both the first surface shape portion 56 and the second surface shape portion 58 have a shape that generates a gripping force when a gripping force is applied in a direction intersecting the optical axis direction D0, a gripping force can also be generated when a gripping force is applied in the optical axis direction D0, thereby improving the convenience of the binoculars 10.

[0086] In addition, in the above embodiment, the first pattern of the first surface shape portion 56 has a first shape portion 56A, a second shape portion 56B and a third shape portion 56C, but it may also have only the first shape portion 56A and the second shape portion 56B, or only the first shape portion 56A and the third shape portion 56C.

[0087] Furthermore, in the above embodiment, the first shape portion 56A, the second shape portion 56B, and the third shape portion 56C are separate from each other, but they can also be connected to each other.

[0088] Furthermore, in the above embodiment, the first surface shape portion 56 is also formed in regions 46A1 and 46A2 adjacent to the recess 54 in the bottom surface 46A. Region 46A1 includes the top 40A region on the bottom surface 46A side of the first lens barrel portion 40, and region 46A2 includes the top 42A region on the bottom surface 46A side of the second lens barrel portion 42. However, the first surface shape portion 56 may also be formed only in either region 46A1 or region 46A2.

[0089] The above variations can be appropriately combined.
