Description

Technical Field

[0001] This utility model relates to an operating device and a shooting device equipped with the operating device. Background Technology

[0002] Previously, operating devices equipped with alternating mechanisms were known. For example, the operating device described in Patent Document 1 is configured to lock the dial in a non-rotating state. Specifically, when the user presses the locking button provided on the dial once, the dial is locked and cannot be rotated; when the locking button is pressed again, the dial returns to a rotatable state. That is, under the action of the alternating mechanism, the dial is transferred from the locked state to the unlocked state or vice versa through a common operation.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2015-125307 Utility Model Content

[0006] The problem to be solved by utility models

[0007] However, in the operating device described in Patent Document 1, when the user presses the locking button, the locking pin emerges from the dial and engages with the locking hole of the housing supporting the dial for rotation. Thus, the dial is locked and cannot rotate. When the user presses the locking button again, the locking pin emerges from the locking hole and returns to the dial. Thus, the dial is unlocked and can rotate. Therefore, in the operating device described in Patent Document 1, the locking button and the locking pin are connected in a manner that allows for detachment along the direction of the dial's rotation center line. That is, the locking button must be temporarily separated from the locking pin. The result of ensuring the travel required for this separation is a larger thickness of the dial (the dimension in the direction extending along the rotation center line).

[0008] Therefore, the objective of this invention is to reduce the thickness of the dial in an operating device equipped with a dial having an alternation mechanism.

[0009] Solution for solving the problem

[0010] To address the aforementioned issues, according to one aspect of this utility model, an operating device is provided, wherein...

[0011] The operating device has:

[0012] Dial; and

[0013] The dial locking component has a recess.

[0015] A locking lever member, movable along the extension direction of the rotation center line of the dial, and having a button portion that can be pressed by the user and a protrusion that, when the button portion is pressed, engages with the recess of the dial locking member to lock the dial in a non-rotatable state; and

[0016] An alternating mechanism that, when the button is pressed by the user in the locked state, moves the locking lever member, thereby setting the dial to an unlocked state where the engagement between the protrusion and the recess is released and it can be rotated.

[0058] Hereinafter, embodiments will be described in detail with appropriate reference to the accompanying drawings. However, sometimes necessary detailed descriptions are omitted. For example, detailed descriptions of well-known matters and repetitive descriptions of substantially the same structures are sometimes omitted. This is to avoid making the following description unnecessarily lengthy and to facilitate understanding by those skilled in the art.

[0059] It should be noted that the inventors have provided the accompanying drawings and the following description in order to enable those skilled in the art to fully understand the present invention, but these are not intended to limit the subject matter of the technical solution described herein.

[0060] The imaging device of the present invention will now be described with reference to the accompanying drawings.

[0061] Figure 1 This is a perspective view of an imaging device according to one embodiment of the present invention. It should be noted that the X-Y-Z orthogonal coordinate system shown in the figure is used to facilitate understanding of the embodiments of the present invention and is not intended to limit the embodiments of the present invention. The X-axis direction is the front-back direction of the imaging device, the Y-axis direction is the left-right direction, and the Z-axis direction is the height direction. Furthermore, in this specification, the side where the subject is located is referred to as the "front side," and the side where the imaging device is located is referred to as the "rear side."

[0062] like Figure 1 As shown, the imaging device 10 of this embodiment includes a housing 12 and a lens holder 14 provided on the front surface 12a of the housing 12 and capable of detachably mounting a lens barrel (not shown). Furthermore, the imaging device 10 includes multiple operating devices such as buttons for user operation. For example, by operating the shutter button 16 provided on the upper surface 12b of the housing 12, the operating devices 18 and 20, the touch display provided on the rear surface 12c of the housing 12, and the buttons, the imaging device 10 performs various functions corresponding to the user's operation.

[0063] Next, further features of the operation devices 18 and 20 in the imaging apparatus 10 of this embodiment will be described. It should be noted that the operation devices 18 and 20 have substantially the same structure, so only the operation device 20 will be described.

[0064] Figure 2 This is a perspective view of the operating device according to one embodiment of the present invention. Additionally, Figure 3 It is an exploded perspective view of the operating device. Furthermore, Figure 4 This is a perspective view of the dial in the operating device from below. Furthermore, Figure 5 This is a cross-sectional view of the dial in its unlocked state.

[0065] like Figure 2 as well as Figure 3 As shown, the operating device 20 includes: a dial 22 that is rotated by a user; a dial locking member 24 that selectively restricts the rotation of the dial 22; a bracket member 26 that fixes the dial locking member 24; and a circuit board 30 that has a contact rotor 28 equipped with a contact brush (not shown) for detecting the rotation angle position of the dial 22 and an electrode portion for which the copper foil portion on the printed wiring has been gold-plated.

[0066] The dial 22 is rotatably supported on the bracket 26 about a rotation center line CL that extends along the height direction (Z-axis direction) of the shooting device 10. Furthermore, the dial 22... Figure 5 It consists of multiple components as shown, details of which will be described later. Details regarding dial 22 will also be described later.

[0067] In this embodiment, the dial locking member 24 is an annular member with multiple locking walls 24a protruding along the extension direction (Z-axis direction) of the rotation center line CL of the dial 22 on its outer periphery. The multiple locking walls 24a are arranged at intervals along the rotation direction R1 of the dial 22. It should be noted that the dial locking member 24 is fixed to the bracket member 26 by means of fixing screws 32.

[0068] The bracket member 26 includes a cylindrical portion 26a through a through hole (not shown) formed in the housing 12 and a fixing portion 26b fixed to the inner surface of the housing 12, which is opposite to the upper surface 12b of the housing 12. Additionally, a [missing information - likely a device or component] is provided inside the cylindrical portion 26a. Figure 4 The shaft portion 40b of the dial 22 shown is supported by a rotatable cylindrical dial support portion 26d. The dial locking member 24 is fixed to the boss portion 26e inside the cylindrical portion 26a of the bracket member 26 by a fixing screw 32.

[0069] The contact rotor 28 is a rotary switch and has a screw portion 28a that connects to the dial 22. Specifically, the screw portion 28a is formed on... Figure 4 The dial 22 shown engages with the threaded hole of its shaft portion 40b. The contact rotor 28 is mounted on the circuit board 30 in a manner that allows it to rotate relative to the circuit board 30 around a rotation center line CL. Furthermore, a contact brush is provided on the surface of the contact rotor 28 facing the circuit board 30, and multiple electrode portions are provided on the circuit board 30, selectively electrically connected according to the contact brush. As the contact rotor 28 rotates, the contact brush, around the rotation center line CL, electrically connects two of the multiple electrode portions. The electrode portions electrically connected by the contact brush differ depending on the rotation angle position of the contact rotor 28. The rotation angle position of the contact rotor 28 can be detected based on the current flowing through the two electrode portions electrically connected by the contact brush. The circuit board 30 outputs a signal corresponding to the rotation angle position of the contact rotor 28 to a controller in the imaging device 10, including a processor such as a CPU. Based on the signal from the circuit board 30, the controller obtains the rotational angle position of the dial 22, which is connected to the contact rotor 28 via its screw portion 28a, and executes an action corresponding to the rotational angle position of the dial 22. That is, different actions of the imaging device 10 are assigned to the dial 22 at each of the predetermined multiple rotational angle positions.

[0070] It should be noted that, in this embodiment, the dial 22 is positioned at multiple predetermined rotational angles by being forced by multiple ball plugs 34. Each ball plug 34 includes a ball 34a that contacts the dial 22 and a spring 34b that applies force to the ball 34a toward the dial 22. The ball 34a and spring 34b are housed in a recess 26c formed in the cylindrical portion 26a of the carrier member 26. Figure 4 As shown, a plurality of recesses 40c are arranged on the inner side of the dial 22 along the rotation direction R1 of the dial 22, each recess containing a portion of the ball 34a of the ball plug 34. By selectively inserting the ball 34a of the ball plug 34 into these plurality of recesses 40c, the dial 22 is positioned at any of a plurality of predetermined rotation angle positions.

[0071] As described above, the dial 22 can be positioned at multiple predetermined rotational angles via the ball plug 34. Furthermore, the dial 22 is configured to be fixed (locked) in any of the multiple predetermined rotational angle positions. That is, the dial 22 is configured to be unable to rotate when positioned.

[0072] Specifically, the dial 22 is configured to switch between an unlocked state (rotatable state) and a locked state (non-rotatable state) according to the user's operation. The structure of the dial 22 will then be described.

[0073] Figure 6A as well as Figure 6B These are exploded 3D views of the top and bottom of the dial.

[0074] like Figure 5 , Figure 6A as well as Figure 6B As shown, the dial 22 includes a dial base 40, a dial cover 42 for user rotation operation, and a locking lever member 44 for fixing the dial 22 relative to the dial locking member 24.

[0075] The dial base 40 includes: a disc-shaped main body 40a; a shaft 40b that extends from the center of the main body 40a along the extension direction of the rotation center line CL (Z-axis direction) and is connected to the screw portion 28a of the contact rotor 28; and a plurality of recesses 40c that engage with the ball 34a of the ball plug 34.

[0076] The dial cover 42 includes a top plate 42a and a cylindrical sidewall portion 42b protruding from the outer periphery of the top plate 42a along the rotation center line CL. A through hole 42c is formed in the center of the top plate 42a, which will be described in detail later. In addition, in this embodiment, the outer peripheral surface of the sidewall portion 42b is knurled. The user holds the outer peripheral surface of the sidewall portion 42b of the dial cover 42, causing the dial 22 to rotate around the rotation center line CL.

[0077] Dial cover 42, etc. Figure 6A as well as Figure 6B As shown, it is mounted to the dial base 40 by a plurality of fixing screws 46. That is, the dial base 40 and the dial cover 42 are fixed so that they cannot be displaced or rotated relative to each other.

[0078] Locking rod component 44 Figure 5 As shown, it includes: a main body 44a, which is stored in the space between the dial base 40 and the dial cover 42; a button 44b, which protrudes from the main body 44a and passes through the through hole 42c of the dial cover 42; and a plurality of protrusions 44c, which engage with the dial locking member 24 to lock the dial 22 so that it cannot be rotated.

[0079] In the dial 22, the locking lever member 44 is provided in a manner that allows it to move along the extension direction (Z-axis direction) of the rotation center line CL. Specifically, the main body 44a of the locking lever member 44 is provided in a manner that allows it to move between the dial base 40 and the dial cover 42 along the extension direction of the rotation center line CL.

[0080] In this embodiment, such as Figure 5 as well as Figure 6B As shown, a plurality of guide pins 42e protruding in the extension direction (Z-axis direction) of the rotation center line CL are provided on the back surface 42d of the top plate 42a of the dial cover 42. A plurality of guide holes 44d guided by the plurality of guide pins 42e are formed in the main body portion 44a of the locking lever member 44. The locking lever member 44 is provided on the dial 22 in such a way that it can move in the extension direction of the rotation center line CL while being restricted from rotation about the rotation center line CL. It should be noted that, in this embodiment, the locking lever member 44 is as follows Figure 6A as well as Figure 6B As shown, it engages with the notch 40f formed on the outer periphery of the dial base 40 in a manner that allows it to move along the extension direction of the rotation center line CL, and is restricted from rotation by the notch 40f.

[0081] The button portion 44b of the locking lever member 44 is exposed to the outside through the through hole 42c of the dial cover 42. Furthermore, the button portion 44b is pressed by the user. When the button portion 44b is pressed by the user, the entire locking lever member 44 is pressed down.

[0082] The plurality of protrusions 44c of the locking lever member 44 selectively restrict the rotation of the dial 22 relative to the dial locking member 24.

[0083] Figure 7A This is a perspective view of the operating device in an unlocked state, showing the dial rotating relative to the dial locking member. Additionally, Figure 7B This is a perspective view of the operating device showing the locked state where the dial cannot rotate relative to the dial locking member. It should be noted that... Figure 7A as well as Figure 7B The dial cover 42 is shown using a double-dotted line so that the interior of the dial 22 can be seen.

[0084] like Figure 7A as well as Figure 7B As shown, the plurality of protrusions 44c of the locking lever member 44 selectively engage with the plurality of recesses 24b of the dial locking member 24. In this embodiment, the plurality of recesses 24b of the dial locking member 24 are gaps between two adjacent locking wall portions 24a in the rotation direction R1 of the dial 22.

[0085] like Figure 7A As shown, in the unlocked state, the plurality of protrusions 44c of the locking lever member 44 do not engage with the plurality of recesses 24b of the dial locking member 24. Therefore, the dial 22 is capable of rotating relative to the dial locking member 24 about the rotation center line CL.

[0086] On the other hand, such as Figure 7B As shown, in the locked state, the plurality of protrusions 44c of the locking lever member 44 enter the plurality of recesses 24b. That is, the movement of the rotation direction R1 of each of the plurality of protrusions 44c is restricted by the plurality of locking walls 24a. Therefore, the dial 22 cannot rotate relative to the dial locking member 24 about the rotation center line CL.

[0087] The dial 22 is configured to alternately switch whenever the user presses the button portion 44b of the locking lever member 44. Figure 7A The unlock status shown is the same as Figure 7B The locked state is shown.

[0088] First, when users... Figure 7A When the button portion 44b of the locking lever member 44 in the unlocked state of the dial 22 is pressed, the locking lever member 44 moves downward as a whole, and as shown... Figure 7B As shown, the plurality of protrusions 44c of the locking lever member 44 engage with the plurality of recesses 24b of the dial locking member 24. As a result, the dial 22 transitions from the unlocked state to the locked state.

[0089] Additionally, when users... Figure 7B When the button portion 44b of the locking lever member 44 in the locked state of the dial 22 is pressed, the locking lever member 44 moves upward as a whole, and as shown... Figure 7A As shown, the multiple protrusions 44c of the locking lever member 44 separate from the multiple recesses 24b of the dial locking member 24. As a result, the dial 22 transitions from the locked state to the unlocked state.

[0090] The pressing operation of the button portion 44b of the locking lever member 44, which becomes the trigger condition, is the same, but the direction of movement of the locking lever member 44 when transitioning from the unlocked state to the locked state (i.e., the downward direction) is different from the direction of movement of the locking lever member 44 when transitioning from the locked state to the unlocked state (i.e., the upward direction). In order to realize this action of the locking lever member 44, the dial 22 includes an alternation mechanism.

[0091] It should be noted that a "transition mechanism" refers to a mechanism that causes the state of the device to transition from a first state to a second state, or vice versa, through the same operation by the user, such as pressing a button. That is, when the device is in the first state during user operation, the device transitions from the first state to the second state. Conversely, when the device is in the second state during user operation, the device transitions from the second state to the first state. In this embodiment, when the dial 22 is in the unlocked state when the user presses the button 44b, the dial 22 transitions from the unlocked state to the locked state. Furthermore, when the dial 22 is in the locked state when the user presses the button 44b, the dial 22 transitions from the locked state to the unlocked state.

[0092] In this embodiment, such as Figure 5 , Figure 6A as well as Figure 6B As shown, the dial 22 includes a coil spring (first force-applying member) 48 that applies force to the locking lever member 44. Specifically, the coil spring 48 applies force to the locking lever member 44 in a direction (first direction) where it engages with the plurality of protrusions 44c of the locking lever member 44 and the plurality of recesses 24b of the dial locking member 24, i.e., in the direction where the locking lever member 44 approaches the dial base 40. In this embodiment, as... Figure 5 As shown, the coil spring 48 is disposed between the top plate 42a of the dial cover 42 and the locking lever member 44. Moreover, the coil spring 48 is inserted into and supported by the guide pin 42e of the dial cover 42.

[0093] Therefore, in this embodiment, the alternation mechanism of the dial 22 is configured to continuously apply force to the locking lever member 44 in the direction opposite to the force application direction of the coil spring 48 (the second direction) when in the unlocked state, with a force greater than that of the coil spring 48. Furthermore, the alternation mechanism is configured to release the force applied to the locking lever member 44 when in the locked state.

[0094] In this embodiment, the alternation mechanism of the dial 22 is as follows: Figure 5 , Figure 6A as well as Figure 6B As shown, it includes a rotating body 50 disposed between the locking lever member 44 and the dial base 40, a helical spring (second force-applying member) 52 that applies force to the rotating body 50, and a rotating body support member 54 that supports the rotating body 50.

[0095] Figure 8 This is a three-dimensional diagram of the rotating bodies included in the alternating mechanism. Additionally, Figure 9 This is a lower perspective view showing the locking rod member of the engaging part that engages with the rotating body.

[0096] like Figure 5 as well as Figure 8As shown, in this embodiment, the rotating body 50 is a cylindrical component. The rotating body 50 has a crown gear-shaped first cam follower 50a on its end face opposite to the locking lever component 44. Figure 5 as well as Figure 9 As shown, a crown gear-shaped cam portion 44e is formed on the locking lever member 44 opposite to the first cam follower 50a of the rotating body 50, capable of meshing with the first cam follower 50a of the rotating body 50. In this embodiment, the button portion 44b of the locking lever member 44 is a bottomed cylindrical shape, and the cam portion 44e is formed on its inner bottom surface. Therefore, at least a portion of the rotating body 50 is housed within the button portion 44b. As a result, compared to the case where at least a portion of the rotating body 50 is not housed within the button portion 44b (for example, compared to the case where the button portion 44b is solid), the dimension in the extension direction (Z-axis direction) of the rotation center line CL of the dial 22 is smaller. It should be noted that... Figure 5 The first cam follower 50a of the rotating body 50 is shown in a state where the cam portion 44e of the locking rod member 44 is not engaged.

[0097] Furthermore, the rotating body 50 has a plurality of convex second cam followers 50b that protrude outwards in a direction intersecting the extension direction (Z-axis direction) of the rotation center line CL. Details regarding the second cam followers 50b will be described later.

[0098] The alternating mechanism's helical spring 52 applies force to the rotating body 50 toward the locking lever member 44. For example... Figure 5 As shown, at least a portion of the helical spring 52 is housed within the cylindrical rotating body 50. As a result, compared to cases where at least a portion of the helical spring 52 is not housed within the rotating body 50 (e.g., compared to cases where the rotating body 50 is solid), the dimension of the dial 22 in the extension direction (Z-axis direction) of its rotation center line CL is smaller. Furthermore, the helical spring 52 as... Figure 5 The dial base 40 is supported by a support pin 40d that is inserted into the main body 40a of the dial base 40 and extends along the extension direction (Z-axis direction) of the rotation center line CL.

[0099] Helical spring 52, etc. Figure 5 As shown, a force greater than the force of the coil spring 48 that applies force to the locking lever member 44 towards the rotating body 50 is applied to the rotating body 50. As a result, the locking lever member 44 contacts the back surface 42d of the top plate 42a of the dial cover 42. Consequently, the button portion 44b of the locking lever member 44... Figure 5 as well as Figure 7AAs shown, it protrudes to its maximum extent from the through hole 42c of the dial cover 42. It should be noted that the force of each of the coil springs 48 and 52 is set to the force that moves the locking lever member 44 when the user presses the button portion 44b of the locking lever member 44 with their fingertip.

[0100] The rotating body support member 54 of the alternating mechanism supports the rotating body 50 so that it can move along the extension direction (Z-axis direction) of the rotation center line CL and rotate around the rotation center line CL.

[0101] Figures 10A to 10D These are the top perspective view, bottom perspective view, top view, and bottom view of the rotating body support component included in the alternating mechanism. It should be noted that... Figure 10C as well as Figure 10D The solid of revolution 50 is indicated by a double-dotted line. Additionally, Figures 11A to 11C These are the top perspective view, bottom perspective view, and bottom view of the rotating body support component, showing its state of supporting the rotating body. It should be noted that... Figures 11A to 11C and Figure 5 as well as Figure 7A Correspondingly shown are the rotating body 50 and the rotating body support member 54 when the dial 22 is in the unlocked state.

[0102] like Figures 10A to 10D As shown, the rotating body support member 54 is equipped with a mechanism to support the rotating body. Figure 8 The outer peripheral surface 50c of the rotating body 50 shown is supported by a cylindrical portion 54a that allows the rotating body 50 to move along the extension direction (Z-axis direction) of the rotation center line CL. Multiple guide grooves 54b are formed in the cylindrical portion 54a, which extend along the extension direction of the rotation center line CL and guide multiple second cam followers 50b of the rotating body 50.

[0103] like Figure 11A as well as Figure 11B As shown, while the second cam follower 50b is within the guide groove 54b, the rotating body 50 cannot rotate within the cylindrical portion 54a of the rotating body support member 54. When the rotating body 50 moves along the extension direction (Z-axis direction) of the rotation center line CL and the second cam follower 50b exits the guide groove 54b, as... Figure 11C As shown, the rotating body 50 becomes capable of rotating about the rotation center line CL along the rotation direction R2. Details about the rotation direction R2 will be described later.

[0104] It should be noted that, in this embodiment, Figure 6B Multiple ribs 44f protruding along the extension direction (Z-axis direction) of the locking lever member 44 shown enter relative to a portion of the guide groove 54b. Thus, the rotation of the locking lever member 44 around the rotation center line CL is restricted.

[0105] In addition, the rotating body support member 54, as Figure 10B , Figure 10D , Figure 11B as well as Figure 11C As shown, a cam surface 54c is provided to drive multiple second cam followers 50b of the rotating body 50 emerging from the guide groove 54b. The cam surface 54c is formed on the end face of the cylindrical portion 54a (the end face on the side farther from the locking lever member 44). The cam surface 54c includes an inclined surface that extends along the rotation direction R2 of the rotating body 50 between the guide grooves 54b. After the second cam followers 50b emerging from the guide groove 54b move to a position opposite the cam surface 54c, they are pressed against the cam surface 54c by the force of the coil spring 52, as will be described in detail later. The pressed second cam followers 50b slide along the rotation direction R2 on the cam surface 54c due to the inclination of the cam surface 54c. As a result, the rotating body 50 rotates as a whole around the rotation centerline CL. It should be noted that, in this embodiment, a stepped limiting part 54d is provided at approximately the center of the inclined surface of the cam surface 54c to restrict the movement of the second cam follower 50b.

[0106] Next, the operation of the components of the dial 22 during transitions from the locked state to the unlocked state and from the unlocked state to the locked state will be explained. The operation of the second cam follower 50b of the rotating body 50 will be explained.

[0107] Figure 12 This diagram schematically illustrates the operation of the second cam follower of the rotating body as the state of the dial changes in the sequence of unlocked, locked, and unlocked states. Specifically, it shows the operation of the second cam follower 50b of the rotating body 50 when viewed from the rotation center line CL at the cylindrical portion 54a of the rotating body support member 54.

[0108] First, when dial 22 is in the unlocked state, such as Figure 5 As shown, the main body 44a of the locking lever member 44 contacts the back surface 42d of the top plate 42a of the dial cover 42, and the locking lever member 44 is separated from the dial base 40 to the maximum extent. As a result, the button portion 44b of the locking lever member 44 protrudes from the through hole 42c of the dial cover 42 by the maximum amount. In addition, the rotating body 50 is also separated from the dial base 40 to the maximum extent. At this time, as Figure 12 As shown, the second cam follower 50b of the rotating body 50 is located at position P0 within the guide groove 54b of the rotating body support member 54. When the second cam follower 50b is at position P0, the rotating body 50 cannot rotate around the rotation center line CL. That is, as... Figure 11AAs shown, the cylindrical portion 54a of the rotating body support 54 has a height (the dimension in the extension direction (Z-axis direction) of the rotation center line CL) such that the rotating body 50 cannot detach from the cylindrical portion 54a when it is maximally separated from the dial base 40. Furthermore, as... Figure 7A As shown, the protrusion 44c of the dial cover 42 does not enter the recess 24b of the dial locking member 24. Furthermore, the cam portion 44e of the locking lever member 44 does not engage with the first cam follower 50a of the rotating body 50.

[0109] When the user presses Figure 5 When the button portion 44b of the locking lever member 44 in the dial 22 is in the unlocked state, the locking lever member 44 presses down the rotating body 50. Thus, as shown... Figure 12 As shown, the second cam follower 50b of the rotating body 50 moves toward the dial base 40 within the guide groove 54b of the rotating body support member 54. It should be noted that... Figure 12 In the diagram, solid and dashed arrows indicate the movement path of the second cam follower 50b. Solid arrows indicate the movement path when pressure (from the user's finger) is applied to the button 44b, and dashed arrows indicate the movement path when no pressure is applied to the button 44b.

[0110] When the user continuously presses the button portion 44b of the locking lever component 44, such as Figure 12 As shown, the second cam follower 50b of the rotating body 50 reaches position P1 outside the guide groove 54b of the rotating body support member 54. Thus, the rotating body 50 is able to rotate around the rotation center line CL.

[0111] When the second cam follower 50b of the rotating body 50 reaches position P1, as Figure 5 As shown, the cam portion 44e of the unlocked locking lever member 44 engages with the first cam follower 50a of the rotating body 50. Specifically, due to engagement, the rotating body 50 begins to rotate in the rotation direction R2. At this time, the button portion 44b of the locking lever member 44 is continuously pressed by the user, so that while both the locking lever member 44 and the rotating body 50 move toward the dial base 40, the rotating body 50 rotates in the rotation direction R2. As a result, as Figure 12 As shown, the second cam follower 50b of the rotating body 50 moves to position P2 between the cam surface 54c of the rotating body support member 54 and the dial base 40 (however, it does not contact the cam surface 54c). It should be noted that the tooth shapes of the cam portion 44e of the locking lever member 44 and the first cam follower 50a of the rotating body 50 are designed so that the rotating body 50 rotates along the rotation direction R2 during engagement.

[0112] Figure 13AThis is a cross-sectional view of the dial with the locking lever member pressed down to its maximum extent from the unlocked state. Additionally, Figure 13B Is with Figure 13A The bottom view of the corresponding rotating body and the rotating body support component.

[0113] like Figure 13A As shown, when the locking lever member 44 is pressed to its maximum extent under the pressure F from the user, i.e. Figure 12 When the second cam follower 50b of the rotating body 50 is in position P2, as shown, the cam portion 44e of the locking lever member 44 is engaged with the first cam follower 50a of the rotating body 50. Furthermore, at this time, the locking lever member 44 contacts the dial base 40, thereby further restricting the user's pressing of the locking lever member 44 (it should be noted that in...). Figure 13A In the cross-section shown, there is no contact between the locking lever member 44 and the dial base 40. Furthermore, the cylindrical portion 54a of the rotating body support member 54 enters the recess 44g formed in the locking lever member 44. That is, the locking lever member 44 and the rotating body support member 54 partially overlap when they are closest. As a result, the thickness of the dial 22 (the dimension in the extension direction (Z-axis direction) of the rotation center line CL) can be reduced without reducing the stroke of the locking lever member 44. Moreover, the coil spring 52 is compressed to the maximum extent. And, as... Figure 13B As shown, when viewed along the extension direction of the rotation center line CL (Z-axis direction), the plurality of second cam followers 50b of the rotating body 50 are each opposite to the cam surface 54c of the rotating body support member 54.

[0114] In such Figure 13A As shown, after the locking lever member 44 is pressed to its maximum extent under the action of the user's pressing force F, when the pressing force F is released (for example, when the user's finger is separated from the button part 44b), the rotating body 50 and the locking lever member 44 move in the direction of separation from the dial base 40 under the action of the force of the coil spring 52. Thus, as Figure 12 As shown, the second cam follower 50b of the rotating body 50 contacts the cam surface 54c of the rotating body support member 54 (position P3).

[0115] like Figure 12As shown, the second cam follower 50b (position P3), which is in contact with the cam surface 54c of the rotating body support member 54, slides on the inclined cam surface 54c due to the force exerted on it by the helical spring 52. As a result, the rotating body 50 rotates around the rotation center line CL, and the engagement between the cam portion 44e of the locking lever member 44 and the first cam follower 50a of the rotating body 50 is released. Furthermore, when the second cam follower 50b contacts the limiting portion 54d on the cam surface 54c, the sliding on the cam surface 54c of the second cam follower 50b stops, that is, the rotation of the rotating body 50 stops (position P4). When the second cam follower 50b is in position P4, the dial 22 is in a locked state.

[0116] Figure 14A This is a cross-sectional view of the dial in its locked state. Additionally, Figure 14B Is with Figure 14A The bottom view of the corresponding rotating body and the rotating body support component.

[0117] In such Figure 12 When the second cam follower 50b of the rotating body 50 contacts the limiting part 54d on the cam surface 54c as shown (position P4), as Figure 14A As shown, the cam portion 44e of the locking lever member 44 is not engaged with the first cam follower 50a of the rotating body 50. Furthermore, the button portion 44b of the locking lever member 44 is lower than the position of the button portion 44b in the unlocked state (the position indicated by the double-dotted line). Additionally, the protrusion 44c of the locking lever member 44 is lower than the position of the protrusion 44c in the unlocked state (the position indicated by the double-dotted line). This is because... Figure 14B As shown, the second cam follower 50b of the rotating body 50 is engaged with the cam surface 54c and the limiting part 54d of the rotating body support member 54, so the rotating body 50 can neither be lifted by the coil spring 50 nor rotate. As a result, the rotating body 50 cannot push the locking lever member 44 until the main body 44a of the locking lever member 44 contacts the back surface 42d of the top plate 42a of the dial cover 42. That is, the force exerted by the coil spring 52 on the locking lever member 44 via the rotating body 50 is released. At this time, as Figure 7B As shown, the front end of the protrusion 44c of the locking lever member 44 is located within the recess 24b of the dial locking member 24. Therefore, the dial 22 is locked in a position where it cannot rotate.

[0118] It should be noted that, as Figure 14AAs shown, the main body 44a of the locking lever member 44 does not contact the back surface 42d of the top plate 42a of the dial cover 42. However, under the force of the coil spring 48, the locking lever member 44 maintains contact with the rotating body 50. Furthermore, even if the shooting device 10 is inverted, the coil spring 48 will not substantially compress or deform due to the weight of the locking lever member 44. That is, the total load of the multiple coil springs 48 is greater than the weight of the locking lever member 44. As a result, the locking lever member 44 cannot move freely in the locked state.

[0119] In addition, such as Figure 5 As shown, in the unlocked state, the main body 44a of the locking lever member 44 is pressed against the back surface 42d of the top plate 42a of the dial cover 42 by the rotating body 50, which is subjected to force by the coil spring 52. As a result, the locking lever member 44 cannot move freely in the unlocked state.

[0120] Thus, the locking lever member 44 cannot move freely in either the locked or unlocked state. Therefore, even if the posture of the shooting device 10 changes in various ways, the locking lever member 44 will not move due to its own weight. Therefore, accidental unlocking and clicking sounds caused by the locking lever member 44 moving freely with various changes in the posture of the shooting device 10 are suppressed.

[0121] In addition, such as Figure 14A As shown, the amount of protrusion of the button portion 44b of the locking lever member 44 from the through hole 42c of the dial cover 42 is different in the locked state and the unlocked state. Therefore, the user can know whether the dial 22 is locked or unlocked by the amount of protrusion of the button portion 44b.

[0122] exist Figure 14A In the locked state of the dial 22, when the user presses the button portion 44b of the locking lever member 44, as shown... Figure 12 As shown, the second cam follower 50b of the rotating body 50 moves from position P4. When the second cam follower 50b separates from the limiting part 54d (position P5), the rotating body 50 can rotate in the rotation direction R2 with the rotation center line CL as the center.

[0123] When the second cam follower 50b of the rotating body 50 reaches position P5, as Figure 14A As shown, the cam portion 44e of the unlocked locking lever member 44 engages with the first cam follower 50a of the rotating body 50. Specifically, due to engagement, the rotating body 50 begins to rotate in the rotation direction R2. At this time, the button portion 44b of the locking lever member 44 is continuously pressed by the user, so that while both the locking lever member 44 and the rotating body 50 move toward the dial base 40, the rotating body 50 rotates in the rotation direction R2. As a result, as Figure 12As shown, the second cam follower 50b of the rotating body 50 moves to position P6 between the cam surface 54c of the rotating body support member 54 and the dial base 40 (however, it does not contact the cam surface 54c).

[0124] Figure 15A This is a cross-sectional view of the dial with the locking lever member pressed down to its maximum extent from the locked position. Additionally, Figure 15B Is with Figure 15A The bottom view of the corresponding rotating body and the rotating body support component.

[0125] like Figure 15A As shown, when the locking lever member 44 is pressed to its maximum extent under the pressure F from the user, i.e. Figure 12 When the second cam follower 50b of the rotating body 50 is in position P6, as shown, the cam portion 44e of the locking lever member 44 is engaged with the first cam follower 50a of the rotating body 50. Furthermore, at this time, the locking lever member 44, by contacting the dial base 40, restricts further pressing of the locking lever member 44 by the user (it should be noted that in...). Figure 15A In the cross-section shown, there is no contact between the locking lever member 44 and the dial base 40. Furthermore, the coil spring 52 is compressed to its maximum extent. And, as... Figure 15B As shown, when viewed along the extension direction of the rotation center line CL (Z-axis direction), the plurality of second cam followers 50b of the rotating body 50 pass over the limiting part 54d along the rotation direction R2 and are opposite to the cam surface 54c of the rotating body support member 54.

[0126] When Figure 15A As shown, after the locking lever member 44 is pressed to its maximum extent under the action of the user's pressing force F, when the pressing force F is released, the rotating body 50 and the locking lever member 44 move in the direction of separation from the dial base 40 under the action of the coil spring 52. Thus, as Figure 12 As shown, the second cam follower 50b of the rotating body 50 contacts the cam surface 54c of the rotating body support member 54 (position P7).

[0127] like Figure 12 As shown, the second cam follower 50b, which contacts the cam surface 54c of the rotating body support member 54 (position P7), slides on the inclined cam surface 54c due to the force exerted by the helical spring 52 towards the cam surface 54c. As a result, the rotating body 50 rotates around the rotation center line CL, and the engagement between the cam portion 44e of the locking rod member 44 and the first cam follower 50a of the rotating body 50 is disengaged. Finally, the second cam follower 50b separates from the cam surface 54c and enters the guide groove 54b (position P8) (see reference). Figure 11A The result is, as Figure 5 , Figure 7A As shown, dial 22 is in the unlocked state.

[0128] That is, when the user performs two press operations on the button part 44b of the locking lever member 44, the second cam follower part 50b of the rotating body 50 moves from one guide groove 54b of the rotating body support member 54 to the guide groove 54b adjacent to that one guide groove 54b.

[0129] Next, the assembly of dial 22 will be explained.

[0130] Figure 16 This diagram illustrates the assembly of the first sub-component in the dial. Additionally, Figure 17 This is a 3D view of the first sub-component. Furthermore, Figure 18 This diagram illustrates the assembly of the second sub-component in the dial. Furthermore, Figure 19 This is a diagram used to illustrate the assembly of the first sub-component and the second sub-component.

[0131] First, such as Figure 16 as well as Figure 17 As shown, in order to manufacture the first sub-assembly 60 in the dial 22, a rotating body 50, a coil spring 52, and a rotating body support member 54 are assembled relative to the dial base 40. Specifically, the rotating body support member 54 is first installed relative to the dial base 40 by a snap-fit ​​engagement. Therefore, the dial base 40 is provided with a snap-fit ​​claw 40e that engages the rotating body support member 54 with the dial base 40 in a manner that prevents it from detaching from the dial base 40. When the rotating body support member 54 is installed and fixed to the dial base 40, the support pin 40d of the dial base 40 is received within the cylindrical portion 54a of the rotating body support member 54.

[0132] Next, the helical spring 52 is installed inside the cylindrical portion 54a of the rotating body support member 54. Then, the rotating body 50 is installed to cover the front end of the helical spring 52. At this time, the rotating body 50 is inserted into the helical spring 52 and supported by the support pin 40d of the dial base 40. Furthermore, the cam follower 50b of the rotating body 50 is inserted into the guide groove 54b of the rotating body support member 54, and the cam follower 50b is rotated until it is locked in the limiting portion 54d, thereby temporarily assembling it inside the cylindrical portion 54a.

[0133] Furthermore, the rotating body 50 is pushed towards the dial base 40 against the force of the helical spring 52. At this time, the second cam follower 50b of the rotating body 50 moves within the guide groove 54b of the cylindrical portion 54a of the rotating body support member 54. When the second cam follower 50b disengages from the guide groove 54b, the rotating body 50 rotates and the second cam follower 50b engages with the cam surface 54c of the rotating body support member 54. Subsequently, the rotating body 50 is subjected to force by the helical spring 52, so the second cam follower 50b of the rotating body 50 slides on the cam surface 54c and finally engages with the limiting portion 54d. As a result, Figure 17 The first sub-component 60 shown is now complete.

[0134] like Figure 18 as well as Figure 19 As shown, to manufacture the second sub-assembly 62 in the dial 22, a coil spring 48 and a locking lever member 44 are assembled relative to the dial cover 42. First, the dial cover 42 is installed with the guide pin 42e facing upwards. Next, the coil spring 48 is installed on the back surface 42d of the dial cover 42, inserted through the guide pin 42e. Furthermore, the locking lever member 44 is installed on the dial cover 42 with the guide pin 42e, through which the coil spring 48 is inserted, entering the guide hole 44d. At this time, the locking lever member 44 is supported from below by the coil spring 48. As a result, the second sub-assembly 62 is completed.

[0135] like Figure 19 As shown, the first sub-assembly 60 is assembled relative to the second sub-assembly 62. That is, the first sub-assembly 60 with the shaft portion 40b of the dial base 40 facing upwards is mounted on the second sub-assembly 62 with the guide pin 42e of the dial cover 42 facing upwards. Furthermore, the first sub-assembly 60 is fixed relative to the second sub-assembly 62 by means of the fixing screw 46. As a result, the dial 22 is completed.

[0136] According to this embodiment described above, the thickness of the dial 22 can be reduced in the operating device 20 equipped with the dial 22 having an alternation mechanism. Specifically, the button portion 44b, which allows the user to press to switch the state of the dial from the unlocked state to the locked state or vice versa, and the protrusion 44c, which selectively fixes the dial 22 to the dial locking member 24, are different parts of the locking lever member 44, which is a single component. Therefore, the button portion 44b does not separate from the protrusion 44c. As a result, the travel required for the button portion 44b to separate is not needed, and the thickness of the dial 22 (the dimension in the extension direction (Z-axis direction) of the rotation center line CL) is smaller.

[0137] The above description illustrates the embodiments of this utility model, but the embodiments of this utility model are not limited thereto.

[0138] For example, in the embodiment described above, the alternation mechanism of the dial 22 is composed of a rotating body 50, a coil spring 52, and a rotating body support member 54. However, the alternation mechanism is not limited to this. The alternation mechanism is not limited in its construction as long as it can move the locking lever member 44 in the direction that releases the engagement between the protrusion 44c of the locking lever member 44 and the recess 24b of the dial locking member 24 after the button portion 44b of the locking lever member 44 is pressed by the user in the locked state.

[0139] That is, the operating device of the present invention, in a broad sense, has a dial and a dial locking member with a recess. The dial includes: a locking lever member that is movable along the extension direction of the rotation center line of the dial and has a button portion that can be pressed by the user and a protrusion that engages with the recess of the dial locking member when the button portion is pressed, thereby setting the dial to a locked state where it cannot be rotated; and an alternation mechanism that, when the button portion is pressed by the user in the locked state, moves the locking lever member, thereby setting the dial to an unlocked state where the engagement between the protrusion and the recess is released and it can be rotated.

[0140] As described above, the embodiments described herein have been presented as examples of the technology in this utility model. For this purpose, accompanying drawings and detailed descriptions are provided. Therefore, the constituent elements described in the drawings and detailed descriptions include not only those necessary to solve the problem, but also those not necessary to solve the problem, which are used to illustrate the technology described above. Therefore, one should not directly assume that these non-essential constituent elements are necessary simply because they are described in the drawings and detailed descriptions.

[0141] Furthermore, the above-described embodiments are used to illustrate the technology in this utility model, and therefore various changes, substitutions, additions, omissions, etc., can be made within the scope of the technical solution or its equivalents.
