DETAILED DESCRIPTION OF THE INVENTION

[0027] An example of an embodiment of the present invention will be described below with reference to the drawings. Note that in this embodiment, the terms "upward," "downward," "leftward," "rightward," "forward," and "rearward" are used, but these directions are relative directions set for the imaging device 1 and the right dial lever 5 of the imaging device 1 shown in the drawings for the sake of convenience.

[0028] <Imaging device according to an embodiment> Fig. 1 is a front view showing a simplified example of an imaging device 1 according to this embodiment. As shown in Fig. 1, an example of an imaging device is a single-lens reflex camera or a digital camera. The imaging device 1 includes a housing 2, an imaging lens 3, a left dial lever 4, and a right dial lever 5.

[0029] The imaging lens 3 is provided at the front (front side) of the housing 2. The imaging lens 3 is detachable from the housing 2. A plurality of types of imaging lenses 3 can be attached to the housing 2 in an interchangeable manner.

[0030] The left dial lever 4 is a dial lever provided on the upper left side of the housing 2. The right dial lever 5 is a dial lever provided on the upper right side of the housing 2. The left dial lever 4 and the right dial lever 5 are used, for example, as dial levers for switching and setting the shooting mode of the imaging device 1. The left dial lever 4 and the right dial lever 5 may also be used as dial levers for setting the shutter speed, ISO sensitivity (ISO: International Organization for Standardization), aperture, etc. of the imaging device 1. The left dial lever 4 and the right dial lever 5 are examples of the "dial device" in the present invention.

[0031] The right dial lever 5 has a first rotary member 20, a second rotary member 40, and a third rotary member 60. The first rotary member 20, the second rotary member 40, and the third rotary member 60 are generally cylindrical rotary members. The first rotary member 20, the second rotary member 40, and the third rotary member 60 are arranged in a vertical line. The first rotary member 20, the second rotary member 40, and the third rotary member 60 are arranged with a portion exposed on the front side of the housing 2. The first rotary member 20 is arranged with a portion of its upper side protruding above the top surface of the housing 2. The second rotary member 40 and the third rotary member 60 are arranged closer to the bottom side of the housing 2 than the top surface of the housing 2. The "top surface" refers to the upper surface of the image capture device 1 when the image capture device 1 is in landscape orientation. The "bottom surface" refers to the lower surface of the image capture device 1 when the image capture device 1 is in landscape orientation. In other words, the second rotary member 40 and the third rotary member 60 of the right dial lever 5 are provided in a state where they do not protrude above the top surface.

[0032] Furthermore, when the imaging device 1 is viewed from the front, a step 6 is provided on the top surface of the housing 2. The step 6 is provided so that the position of the top surface of the area where the left dial lever 4 and imaging lens 3 are provided is higher than the position of the top surface of the area where the right dial lever 5 is provided. By providing the step 6, the position of the upper end of the first rotating member 20, which partially protrudes above the top surface of the housing 2, is configured to be equal to or slightly lower than the position of the top surface of the area where the left dial lever 4 and imaging lens 3 are provided. This enables the imaging device 1 to be made more compact.

[0033] <Dial device of embodiment> Fig. 2 is a front view showing an example of the right dial lever 5 in this embodiment. As shown in Fig. 2, a release button 10 is provided at the upper end of the right dial lever 5. The release button 10 is provided at the upper end of the right dial lever 5. The release button 10, the first rotating member 20, the second rotating member 40, and the third rotating member 60 are arranged along a first axis X1 extending in the vertical direction. The first axis X1 is an axis extending in the vertical direction when the imaging device 1 is in a landscape orientation.

[0034] Of the first rotating member 20, the second rotating member 40, and the third rotating member 60, the first rotating member 20 is the rotating member located at the top. The second rotating member 40 is the rotating member located below (in the middle) the first rotating member 20. The third rotating member 60 is the rotating member located below (at the bottom) the second rotating member 40. The right dial lever 5 is a three-stage dial lever having three rotating members (the first rotating member 20, the second rotating member 40, and the third rotating member 60).

[0035] The first rotating member 20 is a rotating member that includes a protruding on / off lever 21 provided on the outer periphery. The first rotating member 20 can rotate about a first axis X1, for example, by operating the on / off lever 21. For example, by setting the on / off lever 21 to ON, the imaging device 1 is powered on, and by setting the on / off lever 21 to OFF, the imaging device 1 is powered off. The on / off lever 21 is located above the top surface of the housing 2. Note that the on / off lever 21 has a limited rotation range.

[0036] The second rotating member 40 is a rotating member that includes a command dial 41 and an inner dial 42. The command dial 41 can be used to perform exposure compensation, shutter speed setting, quick menu setting value changes, program shift adjustment, aperture value setting, image settings during playback, etc. The inner dial is located inside the command dial 41 and rotates together with the command dial 41. The command dial 41 can rotate infinitely.

[0037] The third rotating member 60 is a rotating member including a protruding digital teleconverter lever 61 provided on the outer periphery. The third rotating member 60 can be rotated around a first axis X1, for example, by operating the digital teleconverter lever 61. The digital teleconverter lever 61 can, for example, switch between capturing enlarged images of different focal lengths using digital super-resolution processing. Note that the digital teleconverter lever 61 has a limited rotation range.

[0038] Fig. 3 is a top view of the right dial lever 5. Fig. 4 is a perspective view of the right dial lever 5 from the upper left. As shown in Figs. 3 and 4, the right dial lever 5 is provided on the front side in the upper right region of the housing 2.

[0039] An opening 7 is provided on the front surface of the housing 2. The "front surface" refers to the surface facing forward (toward the subject) during imaging. The opening 7 is a portion that opens toward the outside (side) of the housing 2. The opening 7 is formed in, for example, a rectangular shape from the top surface to the bottom surface on the front surface of the housing 2.

[0040] Furthermore, a grip portion 2a to be held by the user is provided on the front surface of the housing 2. The "grip portion 2a" is a portion that bulges forward so that the user can easily hold it with their hand when capturing an image. The opening 7 is provided to include at least a portion of the grip portion 2a that bulges forward.

[0041] The first rotating member 20, the second rotating member 40, and the third rotating member 60 are arranged in the opening 7. "Arranged in the opening 7" means that they are arranged so as to be exposed to the outside of the housing 2 through the opening 7. When viewed from the direction of the first axis X1, the first rotating member 20, the second rotating member 40, and the third rotating member 60 are arranged so that at least a portion of their outer peripheries are exposed from the opening 7. The portion of the outer peripheries of the first rotating member 20, the second rotating member 40, and the third rotating member 60 exposed from the opening 7 has a shape that follows the outer edge of a protruding portion (e.g., a curved portion) on the front side of the grip portion 2a.

[0042] The first rotating member 20, the second rotating member 40, and the third rotating member 60 are disposed inside the housing 2 except for the exposed portions. However, when viewed vertically, the three stacked rotating members are disposed with the topmost first rotating member 20 protruding upward from the top surface of the housing 2, as described above, and the middle second rotating member 40 and the bottom third rotating member 60 disposed below the top surface of the housing 2. The second rotating member 40 of the right dial lever 5 is shielded when viewed from the direction of the first axis X1. "Shielded" means that it is shielded by the top surface of the housing 2 or other members of the imaging device 1, such as the first rotating member 20, and is therefore completely or almost invisible.

[0043] When viewed in the direction of the first axis X1, the portion of the outer periphery of the second rotating member 40 that is exposed through the opening 7 is less than half of the outer periphery of the second rotating member 40. Furthermore, when viewed in the direction of the first axis X1, the portion of the outer periphery of the third rotating member 60 that is exposed through the opening 7 is less than half of the outer periphery of the third rotating member 60. "Half of the outer periphery" means that the length of the exposed portion of the outer periphery of the rotating member is half the length of the entire circumference of the outer periphery. When viewed in the direction of the first axis X1, the portion of the outer periphery of the second rotating member 40 that is exposed through the opening 7 may be less than one-quarter of the outer periphery of the second rotating member 40. Furthermore, when viewed in the direction of the first axis X1, the portion of the outer periphery of the third rotating member 60 that is exposed through the opening 7 may be less than one-quarter of the outer periphery of the third rotating member 60.

[0044] When viewed from the direction of the first axis X1, the first rotating member 20, the second rotating member 40, and the third rotating member 60 have a portion exposed from the opening 7 that is concentric and has an arc shape with the same diameter. The term "concentric and has an arc shape" includes a substantially arc shape with a substantially identical center and a substantially identical diameter. For example, the outer peripheral surface of the second rotating member 40 has small irregularities, and this shape is also included.

[0045] Fig. 5 is a perspective view showing the opening 7 with the first rotary member 20, the second rotary member 40, and the third rotary member 60 removed. As shown in Fig. 5, wall members 2b1 and 2b2 shaped to surround the first rotary member 20, the second rotary member 40, and the third rotary member 60 are provided inside the housing 2. The wall members 2b1 and 2b2 are formed in an arc shape that surrounds the rotary members with the left end 71a and the right end 71b of the opening 7 as the start point and the end point, respectively.

[0046] Figure 6 is a cross-sectional view taken along the first axis X1 of the right dial lever 5. As shown in Figure 6, the right dial lever 5 has a release button 10 attached to the upper side of the first rotating member 20. The right dial lever 5 also has a base member 2c that maintains the position of the right dial lever 5, a first holder member 22 fastened to the base member 2c, and a second holder member 43 and a third holder member 62 fastened to the first holder member 22.

[0047] The first holder member 22 is fastened to the base member 2c along the first axis X1 by fastening members such as screws 23. The second holder member 43 and the third holder member 62 are fastened to the first holder member 22 along the first axis X1 by fastening members such as screws 63. The second holder member 43 and the third holder member 62 are fixed to the base member 2c via the first holder member 22. The base member 2c is fixed to the housing 2. Alternatively, the base member 2c may be a part of the housing 2.

[0048] The second rotating member 40 is held by the first holder member 22 and the second holder member 43. The third rotating member 60 is held by the second holder member 43 and the third holder member 62. The second rotating member 40 is rotatable around the first holder member 22. The third rotating member 60 is rotatable around the second holder member 43.

[0049] The command dial 41 of the second rotating member 40 is made of a metal material. The inner member 42 of the second rotating member 40 is made of a resin material. The inner member 42 is attached to the inside of the command dial 41 by press-fitting or adhesive bonding. The inner member 42 rotates around the first holder member 22 together with the command dial 41. The inner member 42 is provided with a stopper portion 44 that engages with the command dial 41 and ensures a gap between the second rotating member 40 (command dial 41) and the third rotating member 60. Note that the third rotating member 60, like the command dial 41, is also made of a metal material. By providing the stopper portion 44 on the inner member 42 in this manner, it is possible to prevent friction between the command dial 41 of the second rotating member 40 and the third rotating member 60. This improves the drip-proof performance of the housing 2.

[0050] The second rotating member 40 is also provided with a click mechanism that imparts a clicking sensation to the rotation of the second rotating member 40. The click mechanism includes an elastic member 45, such as a spring, and a spherical body 46, such as a ball. The elastic member 45 and the spherical body 46 are arranged in a vertical direction along the first axis X1 in a hole 47 formed in the inner member 42. The hole 47 in which the elastic member 45 and the spherical body 46 are arranged is formed at opposing positions across the first axis X1 in the circumferential direction of the inner member 42. The first holder member 22 is provided in contact with the upper side of the inner member 42, and the first holder member 22 is provided with a plurality of recesses 48 at predetermined intervals in the circumferential direction. The recesses 48 are arranged to be engageable with the spherical body 46.

[0051] The click mechanism is configured so that the sphere 46 arranged in the hole 47 of the inner 42 comes into contact with the first holder member 22 due to the biasing force of the elastic member 45. When the second rotating member 40 rotates, the positions of the hole 47 in which the elastic member 45 and the sphere 46 are arranged move sequentially in the rotation direction, and as the hole 47 moves, the recess 48 that engages with the sphere 46 biased by the elastic member 45 changes sequentially. The click feeling is a response given to the user at a specific rotation angle (e.g., a periodic rotation angle) in response to the rotation operation of the second rotating member 40. For example, the click feeling is an operational feeling in which the force required for rotation repeatedly becomes stronger and weaker depending on the amount of rotation of the second rotating member 40.

[0052] FIG. 7 is a perspective view showing the inner 42 of the second rotating member 40. As shown in FIG. 7, the inner 42 has a generally cylindrical shape. The inner 42 is provided with a stopper portion 44 and a protrusion 49. The stopper portion 44 is a visor-shaped portion provided around the entire circumference of the lower part of the inner 42, and as described above, is the portion that engages with the command dial 41. The protrusion 49 is a protrusion-shaped portion provided on the outer periphery of the inner 42 and fits into a hole formed on the inside of the command dial 41. By fitting the protrusion 49 into the hole of the command dial 41, the inner 42 rotates around the first holder member 22 together with the command dial 41. In addition, a first gear portion 50 is provided at the lower end of the inner 42. The first gear portion 50 is a gear-shaped portion provided at the lower end of the inner 42.

[0053] FIG. 8 is a perspective cross-sectional view showing the first gear portion 50 of the inner member 42. As shown in FIG. 8, the first gear portion 50 of the inner member 42 is disposed rearward of the third rotating member 60. A gear member 51, which is a separate member from the inner member 42, is disposed adjacent to the first gear portion 50 (in this example, adjacent to the right rear of the first gear portion 50). The gear member 51 has a second gear portion 52 that engages with the first gear portion 50 of the inner member 42. The size of the gear member 51 is smaller than the size of the gear member of the inner member 42 that has the first gear portion 50. The gear member 51 rotates around a second axis X2. The second axis X2 of the gear member 51 is an axis parallel to the first axis X1 of the inner member 42. A wall member 2b1 is formed along the first gear portion 50 and the second gear portion 52, as described in FIG. 5, and is formed with the left end 71a and the right end 71b of the opening 7 as its starting point and its ending point.

[0054] FIG. 9 is a side view showing the first gear portion 50 and the second gear portion 52. As shown in FIG. 9, the gear member 51 is disposed adjacent to the inner member 42 with the second gear portion 52 engaged with the first gear portion 50 of the inner member 42. The gear member 51 has a shaft portion 53 disposed along the second axis X2. The shaft portion 53 is provided with an encoder 54 that detects rotation of the shaft portion 53. The encoder 54 detects rotation of the inner member 42 (second rotating member 40) by detecting rotation of the shaft portion 53 of the gear member 51. The encoder 54 is an example of a "first detector" in the present invention.

[0055] 10 is a view of the gear member 51 and the third rotating member 60 as viewed from below. As shown in FIG. 10, when viewed in the direction of the first axis X1, the third rotating member 60 has an outer circumferential surface 64 that follows a circle C whose center is the first axis X1. The circle C is an imaginary circle whose center is the first axis X1. The outer circumferential surface 64 is a portion of the outer periphery of the third rotating member 60 that is exposed through the opening 7 of the housing 2. When viewed in the direction of the first axis X1, the shaft portion 53 of the gear member 51 that is arranged along the second axis X2 is provided so that a portion of it overlaps with the circle C.

[0056] In the above embodiment, the right dial lever 5 is described as the dial device, but the present invention is not limited to this. The configuration of the dial device described above may also be applied to the left dial lever 4.

[0057] As described above, the right dial lever of this embodiment includes the first rotary member 20, the second rotary member 40, and the third rotary member 60, which are arranged along the first axis X1. At least the second rotary member 40 and the third rotary member 60 are arranged in the opening 7, which is provided so as to open toward the outside of the housing 2 of the image capture device 1. The second rotary member 40 and the third rotary member 60 arranged in the opening 7 are positioned below the top surface of the housing 2 and are arranged so that a portion of their outer peripheries are exposed to the outside of the housing 2 through the opening 7. If a dial lever with a three-stage structure having three rotary members were to be configured, the size in the direction of the first axis X1 (vertical direction), which is the rotation axis, would be large (long). In contrast, by arranging at least the second rotary member 40 and the third rotary member 60 inside the housing 2 as in this configuration, it is possible to prevent the size of the housing 2 in the vertical direction, where the right dial lever 5 is provided, from increasing. This prevents the image capture device 1 from becoming large even when a right dial lever 5 with a three-stage structure is installed.

[0058] Furthermore, the second rotating member 40 and the third rotating member 60 are positioned so that a portion of their outer peripheries is exposed to the outside of the housing 2 through the opening 7, so that even when they are positioned inside the housing 2, the user can easily operate the second rotating member 40 and the third rotating member 60 through the opening 7.

[0059] Furthermore, in the three-stage rotating member, the second rotating member 40 (command dial) is located below the first rotating member 20 (on / off lever). Comparing the second rotating member 40 (command dial) and the third rotating member 60 (teleconverter lever), the command dial is used more frequently than the teleconverter lever. Therefore, locating the command dial next to (directly below) the on / off lever makes it easier for the user to operate when operating the on / off lever with the index finger and then lowering the index finger to operate the command dial, or when operating the command dial with the middle finger.

[0060] The right dial lever 5 is disposed in an opening 7 in which the second rotary member 40 and the third rotary member 60 are provided on the front surface of the housing 2. The grip portion 2a of the imaging device 1, which is held by the user, is provided on the front surface of the housing 2, and the opening 7 is provided to include at least a portion of the grip portion 2a. With this configuration, the opening 7 is formed in the grip portion 2a, which protrudes from the front side of the housing 2, and therefore the outer peripheries of the second rotary member 40 and the third rotary member 60 exposed from the opening 7 are shaped to conform to the protruding shape of the grip portion 2a. Therefore, even if the second rotary member 40 and the third rotary member 60 are disposed inside the housing 2, the user can easily operate the second rotary member 40 and the third rotary member 60 exposed from the opening 7 while holding the grip portion 2a.

[0061] Furthermore, since an opening 7 is formed in the grip portion 2a that is raised toward the front, even if the portion of the second rotating member 40 and the third rotating member 60 exposed from the opening 7 is, for example, less than half, or even less than one-fourth, of the outer periphery of the second rotating member 40 and the third rotating member 60, it is possible to easily operate the second rotating member 40 and the third rotating member 60 from the opening 7.

[0062] The right dial lever 5 also includes a first holder member 22 fastened to the base member 2c along the first axis X1, and a second holder member 43 and a third holder member 62 fastened to the first holder member 22 along the first axis X1, with the second rotating member 40 being held by the first holder member 22 and the second holder member 43, and the third rotating member 60 being held by the second holder member 43 and the third holder member 62. With this configuration, the second rotating member 40 and the third rotating member 60 are positioned along the same first axis X1, thereby improving the concentricity accuracy of the rotating members.

[0063] The right dial lever 5 also has a click mechanism including an elastic member 45 and a sphere 46 that imparts a clicking sensation to the rotation operation of the second rotating member 40, and the elastic member 45 and the sphere 46 are arranged along the first axis X1 in a hole 47 provided in the inner 42 of the second rotating member 40. By arranging the elastic member 45 and the sphere 46 in the hole 47 of the inner 42 in this way, it is possible to prevent the size (height) of the second rotating member 40 in the direction of the first axis X1 from increasing, and the right dial lever 5 can be made more compact.

[0064] The right dial lever 5 has a first gear portion 50 below the inner circumferential member 42 of the second rotating member 40, a gear member 51 including the second gear portion 52 and a shaft portion 53 arranged along the second axis X2 as a member that engages with the first gear portion 50 of the inner circumferential member 42, and an encoder 54 as a device that detects the rotation of the shaft portion 53. When viewed in the direction of the first axis X1, the third rotating member 60 has an outer peripheral surface 64 that follows a circle C centered on the first axis X1, and the shaft portion 53 of the gear member 51 that engages with the first gear portion 50 of the inner circumferential member 42 is arranged so as to have an overlapping portion with the circle C. With this configuration, the small gear member 51 that engages with the first gear portion 50 of the inner circumferential member 42 is provided adjacent (to the side) of the first gear portion 50, and the amount of rotation of the gear member 51 can be detected by detecting the amount of rotation of the second rotating member 40 (command dial). Therefore, since there is no need to provide an encoder on the command dial that directly detects the rotation of the second rotating member 40 (command dial), it is possible to prevent the size of the right dial lever 5 in the first axis X1 direction (vertical direction) from becoming large (long).

[0065] In addition, the right dial lever 5 is provided with wall members 2b1 and 2b2 shaped to surround the first rotating member 20, the second rotating member 40, the third rotating member 60, the first gear portion 50, and the second gear portion 52. This configuration makes it possible to prevent dust, water droplets, etc. that have entered through the opening 7 from entering further into the housing 2 behind the right dial lever 5.
