Summary of the Invention

[0005] One embodiment according to the technology of the present disclosure provides a lens barrel and an imaging device capable of suppressing operation sound when an operation member is in a restricted state.

Means for Solving the Problems

[0006] The lens barrel of the present invention includes a lens barrel main body that holds an optical system, an operation member provided on the lens barrel main body for adjusting the optical function of the optical system, a regulation position that regulates the operation of the operation member, and a release position that allows the operation of the operation member. A first member that is movably provided between the two and has a first inclined surface that is inclined with respect to the moving direction from the release position toward the regulation position, and a second member that is provided between the first member and the operation member and has a second inclined surface. When the first member is in the regulation position, the operation member is in a regulated state where its movement is restricted by receiving pressure from the first member via the second member. When the first member is in the release position, the pressure from the first member is released, resulting in a released state where the second member and the operation member are separated from each other.

[0007] The imaging device of the present invention preferably includes the lens barrel of the present invention described above and a camera body.

[0008] The first member preferably includes the first inclined surface and has a tapered cross-sectional shape in the thickness direction that intersects the moving direction. The second member preferably includes the second inclined surface and has a tapered cross-sectional shape in the thickness direction.

[0009] The first inclined surface and the second inclined surface preferably engage with each other. The second inclined surface is preferably disposed at a position facing the first member.

[0010] When the first member moves to the release position, it is preferable to set the operation member in the released state. When the first member is in the regulation position, the second member preferably sets the operation member in the regulated state.

[0011] When the first member is in the regulation position, it is preferable that the second member receives pressure from the first member, and the operation member is in a regulated state where its movement is restricted by receiving pressure from the first member via the second member. The second member preferably frictionally locks the operation member to set it in the regulated state, and is set in the released state when the pressure from the first member is released.

[0012] The first member has a first thick portion and a first thin portion whose dimension in the thickness direction intersecting the moving direction is smaller than that of the first thick portion. The second member has a second thick portion and a second thin portion whose dimension in the thickness direction is smaller than that of the second thick portion. When the first member moves to the restricting position, it is preferable that the first thick portion and the second thick portion come into contact with each other to press the second member toward the operating member side.

[0013] When the first member moves to the release position, the first thick portion and the second thin portion face each other, and the second thick portion and the first thin portion face each other to release the pressing force on the second member. It is preferable that the second member is separated from the operating member when the pressing force from the first member is released.

[0014] The operating member preferably faces a tangential surface that is tangent to the outer peripheral surface of the lens barrel or an attachment surface that is recessed from the outer peripheral surface. The operating member is preferably a rotating member that rotates within the tangential surface. The operating member is preferably a rotating member that rotates around a rotation axis orthogonal to the attachment surface.

[0015] The first member is preferably provided coaxially with the operating member and rotatably between the restricting position and the release position. One of the second member and the lens barrel preferably has a recess extending in a direction parallel to the rotation axis, and the other of the second member and the lens barrel preferably has a protrusion that fits slidably with the recess.

[0016] A plurality of first inclined surfaces are preferably provided on the first member, and the same number of second inclined surfaces as the first inclined surfaces are preferably provided on the second member.

[0017] The first inclined surfaces are preferably provided at equal angular intervals around the rotation axis, and the second inclined surfaces are preferably provided at equal angular intervals around the rotation axis. The first inclined surfaces and the second inclined surfaces are preferably arranged at intervals of 180° around the rotation axis.

[0018] The operating member faces a tangential surface that is tangent to the outer peripheral surface of the lens barrel or an attachment surface that is recessed from the outer peripheral surface, and the first member is preferably a sliding member that slides between the release position and the restricting position.

[0019] The operating member is preferably a push button that faces a tangent surface that is tangent to the outer peripheral surface of the lens barrel or an attachment surface that is recessed from the outer peripheral surface, and moves forward and backward along an attachment axis that intersects the tangent surface or the attachment surface.

[0020] The lens barrel is detachable from the camera body, and it is preferable that the operating member and the first member are provided around the lens barrel on the side opposite to the grip portion of the camera body. The operating member and the first member use the position vertically above in the circumferential direction of the lens barrel as a reference position, and when the camera body side in the optical axis direction of the optical system is defined as the back side and the subject side opposite to the camera body side is defined as the front side, it is preferably provided on the left side surface side around the lens barrel with the reference position as a reference point. Further preferably, the operating member and the first member are arranged within a range of 0° to 90° around the optical axis of the optical system with the reference position as a reference point.

[0021] It is provided with a processor that switches the function to be executed according to the operation by the operating member. When the lens barrel is attached to the camera body, the processor preferably performs control to operate the camera body according to the operation by the operating member instead of adjusting the optical function.

Mode for Carrying Out the Invention

[0023] [First Embodiment] As shown in FIG. 1, the digital camera 10 includes a camera body 11 and an interchangeable lens barrel 12. The camera body 11 corresponds to the camera main body in the claims. On the front surface of the camera body 11, a lens mount 13, a release switch 14, a power switch (not shown), and the like are provided. The lens mount 13 has a circular imaging aperture 13A. The lens barrel 12 is detachably attached to the lens mount 13. The digital camera 10 is an example of the imaging device according to the present invention.

[0024] The camera body 11 incorporates an imaging device 16. The imaging device 16 is, for example, a CMOS (Complementary Metal Oxide Semiconductor) image sensor, a CCD (Charge Coupled Device) image sensor, or an organic thin film imaging device. The lens mount 13 is provided with a body-side signal contact 17 (see FIG. 10) for electrically connecting to and communicating with the lens barrel 12 inside the imaging aperture 13A. Further, the camera body 11 has a grip portion 11A that bulges forward from the left side (right side for the user holding the camera body 11) in a front view.

[0025] As shown in FIG. 2, the lens barrel 12 includes a lens barrel main body 21, an imaging optical system 22, a focus ring 23, a dial operation member 24, a regulation operation member 25, and a mode switching operation member 26. The lens barrel main body 21 has a cylindrical shape and holds the imaging optical system 22 inside, and a lens mount 27 and a lens-side signal contact 28 (see FIG. 14) are provided at the rear end. The imaging optical system 22 forms an image of subject light on the imaging device 16 when the lens barrel 12 is attached to the camera body 11.

[0026] A focus ring 23 is rotatably provided around the optical axis O of the imaging optical system 22 on the outer periphery of the lens barrel main body 21. By manually rotating the focus ring 23 by the imaging person, the focus lens 22a described later is moved to enable focus adjustment of the imaging optical system 22.

[0027] The dial operation member 24 is provided around the lens barrel main body 21, specifically, on the outer peripheral surface of the lens barrel main body 21. The dial operation member 24 corresponds to the operation member and the rotating member in the claims. The dial operation member 24 is rotatably supported about a rotation axis CL1 that intersects the optical axis O of the imaging optical system 22. It is preferable that the rotation axis CL1 is orthogonal to the optical axis O. The dial operation member 24 adjusts the shutter speed as an optical function of the imaging optical system 22. Specific examples of adjusting the optical function including the shutter speed will be described later.

[0028] The mode switching operation member 26 is provided around the lens barrel main body 21, specifically, on the outer peripheral surface of the lens barrel main body 21. The mode switching operation member 26 is a mode switching switch for switching to any one of a plurality of modes selected by the user. The mode switching operation member 26 is a rotating member that is rotatably supported about a rotation axis different from the rotation axis CL1.

[0029] As shown in FIG. 3, the dial operation member 24 and the regulation operation member 25 are provided around the lens barrel 12 on the opposite side of the grip portion 11A of the camera body 11. More specifically, as shown in FIG. 4, with the position vertically above the lens barrel main body 21 as the reference position P0 and the side of the lens barrel main body 21 on the camera body 11 side in the optical axis direction OA as the back side and the subject side opposite to the camera body 11 side as the front side, it is preferably provided within the range E1 on the left side surface around the lens barrel main body 21 with the reference position P0 as the base point.

[0030] In this case, it is assumed that the user holds the camera body 11 with the right hand and holds the lens barrel 12 with the left hand. Thereby, the user can easily operate the dial operation member 24 and the regulation operation member 25 using only the finger (for example, the thumb) of the left hand. It is more preferable that the dial operation member 24 and the regulation operation member 25 are arranged within the range E2 of 0° to 90° around the optical axis O of the imaging optical system 22 with the reference position P0 as the base point.

[0031] The regulation operation member 25 constitutes a regulation mechanism 29 described later. The regulation operation member 25 corresponds to the first member in the claims. The regulation operation member 25 is rotatably provided between a release position (the position shown in FIG. 5(A)) and a regulation position (the position shown in FIG. 5(B)) about the rotation axis CL1 of the dial operation member 24. Note that the difference in position between the "regulation position" and the "release position" includes not only the case where the three-dimensional position of the first member is different, but also the case where only the rotational positions of the "regulation position" and the "release position" are different, such as the dial operation member 24 of the present embodiment. By rotating the regulation operation member 25, it is possible to switch between a regulation state in which the dial operation member 24 is regulated and a release state in which the regulation state is released. That is, when the regulation operation member 25 is in the regulation position, the regulation mechanism 29 is in a regulation state in which the dial operation member 24 is regulated, and when the regulation operation member 25 is in the release position, the regulation mechanism 29 releases the regulation state and becomes a release state in which the rotation of the dial operation member 24 is allowed. Note that "regulation" means that the dial operation member 24 receives pressure from the regulation operation member 25 via a cam member 33 described later.

[0032] As shown in FIG. 6, the dial operation member 24 includes an operation member main body 24A, a male screw 24B, and a light-shielding member 24C. The operation member main body 24A has a female screw hole 24D at the center. The dial operation member 24 is attached to the attachment piece 32 via a shaft member 31. The attachment piece 32 is fixed, for example, by screwing and constitutes a part of the lens barrel main body 21.

[0033] The regulation mechanism 29 includes a regulation operation member 25, a shaft member 31, an attachment piece 32, and a cam member 33. The attachment piece 32 is formed in an arc shape continuous with the outer peripheral surface 21A (see FIGS. 3 and 4) of the lens barrel main body 21. The attachment piece 32 has a concave portion 32A, an attachment surface 32B, a through hole 32C, a protrusion 32D, and a key protrusion 32E. The key protrusion 32E corresponds to the convex portion in the claims.

[0034] The recessed portion 32A is a portion recessed with respect to the outer peripheral surface 21A. The restricting operation member 25 is disposed inside the recessed portion 32A. The mounting surface 32B is formed inside the recessed portion 32A, is a flat surface recessed from the outer peripheral surface 21A, and is a surface orthogonal to the rotation axis CL1.

[0035] The through-hole 32C is a circular through-hole penetrating the mounting piece 32. The through-hole 32C communicates with the mounting surface 32B. The protruding strip portion 32D is formed in an arc shape along the periphery of the mounting surface 32B and protrudes radially outward with respect to the outer peripheral surface 21A.

[0036] A plurality of key protrusions 32E are provided on the inner peripheral surface of the protruding strip portion 32D. The key protrusions 32E extend in a direction parallel to the rotation axis CL1 and fit into key grooves 39 of a cam member 33 described later. In the example shown in FIG. 6, three key protrusions 32E are formed on the inner peripheral surface of the protruding strip portion 32D and are arranged at intervals of 120° around the rotation axis CL1. Further, the key protrusions 32E are located outside the restricting operation member 25 and do not prevent the movement of the restricting operation member 25.

[0037] The shaft member 31 is formed in a columnar shape and rotatably fits into the through-hole 32C of the mounting piece 32. The tip of the shaft member 31 has a female screw hole 31A. A male screw 24B is screwed into the female screw hole 24D of the operation member main body 24A. The male screw 24B is fastened and fixed to the female screw hole 31A of the shaft member 31. Thereby, the shaft member 31 is coupled to the dial operation member 24. That is, the shaft member 31 rotates integrally with the dial operation member 24. Further, for example, an adhesive is applied to the tip surface of the operation member main body 24A, and the light-shielding member 24C is attached. Thereby, the male screw 24B is covered by the light-shielding member 24C.

[0038] The base end portion 31B of the shaft member 31 is formed in a D-cut shape. The base end portion 31B is connected to a rotation amount detection sensor 34 located inside the lens barrel main body 21. The rotation amount detection sensor 34 is a well-known optical or contact type sensor or the like, and detects the rotation amount of the dial operation member 24 via the shaft member 31. The rotation amount detection sensor 34 is attached inside the lens barrel main body 21 via a substrate (not shown) or the like. Also, the movement of the shaft member 31 along the rotation axis CL1 is restricted.

[0039] The regulation operation member 25 is arranged inside the recess 32A and at a position facing the mounting surface 32B. The regulation operation member 25 has a first cam portion 36 and a finger hook portion 37. When the user operates the regulation operation member 25, the user hooks a finger on the finger hook portion 37 and rotates the regulation operation member 25. The first cam portion 36 is formed in a disc shape with an outer diameter smaller than that of the dial operation member 24. A through hole 36A is formed at the center of the first cam portion 36. The through hole 36A fits with the shaft member 31. Thereby, the regulation operation member 25 is rotatably supported around the rotation axis CL1. That is, the regulation operation member 25 is provided coaxially with the dial operation member 24. Hereinafter, the direction in which the regulation operation member 25 moves from the release position toward the regulation position is defined as the movement direction R1, and the direction in which the regulation operation member 25 moves from the regulation position toward the release position is defined as the movement direction R2.

[0040] The finger hook portion 37 moves inside the recess 32A when the regulation operation member 25 rotates. When the regulation operation member 25 is in the release position (the position shown in Fig. 5(A)) and the regulation position (the position shown in Fig. 5(B)), the finger hook portion 37 abuts against the end portion of the recess 32A. Thereby, the regulation operation member 25 is rotatable between the release position and the regulation position around the rotation axis CL1.

[0041] As shown in Fig. 7, the first cam portion 36 has two first inclined surfaces 36B. The first inclined surface 36B is an inclined surface inclined with respect to the moving direction R1. The first inclined surfaces 36B are provided at intervals of 180° around the rotation axis CL1. Note that the number and arrangement of the first inclined surfaces 36B are not limited to this, and a plurality of first inclined surfaces 36B may be provided on the first cam portion 36 and arranged at equal angular intervals around the rotation axis CL1.

[0042] As shown in Figs. 8 and 9, the first cam portion 36 includes the first inclined surface 36B, and the cross-sectional shape in the thickness direction is tapered. More specifically, the portion of the first cam portion 36 including the first inclined surface 36B is tapered such that the dimension in the thickness direction gradually decreases toward the moving direction R1. Here, the thickness direction refers to a direction orthogonal to the moving direction R1 and parallel to the rotation axis CL1. Since the first cam portion 36 is tapered in this way, it has a first thick portion 36C and a first thin portion 36D whose dimension in the thickness direction is smaller than that of the first thick portion 36C.

[0043] The cam member 33 corresponds to the second member in the claims. The cam member 33 is provided between the regulation operation member 25 and the dial operation member 24. The cam member 33 has a second cam portion 38 and a key groove 39. The key groove 39 corresponds to the recess in the claims. The second cam portion 38 is formed in a disc shape with an outer diameter smaller than that of the dial operation member 24. A through hole 38A is formed at the center of the second cam portion 38. The through hole 38A fits with the shaft member 31. The same number of key grooves 39 as the key projections 32E are formed on the outer peripheral surface of the second cam portion 38 and extend in a direction parallel to the rotation axis CL1. In the example shown in Fig. 6, three key grooves 39 are formed on the outer peripheral surface of the second cam portion 38 and arranged at intervals of 120° around the rotation axis CL1.

[0044] As shown in FIG. 7, the second cam portion 38 has two second inclined surfaces 38B. The second inclined surfaces 38B are disposed at positions facing the regulation operation member 25 and are inclined surfaces inclined with respect to the moving direction R1. The second inclined surfaces 38B are provided at intervals of 180° around the rotation axis CL1. Note that the number and arrangement of the second inclined surfaces 38B are not limited to this. For example, the same number of second inclined surfaces 38B as the first inclined surfaces 36B are provided, and it is preferable that they are arranged at equal angular intervals around the rotation axis CL1.

[0045] As shown in FIGS. 10 and 11, the second cam portion 38 includes the second inclined surface 38B, and the cross-sectional shape in the thickness direction is tapered. More specifically, in the second cam portion 38, the portion including the second inclined surface 38B has a tapered shape in which the dimension in the thickness direction gradually increases toward the moving direction R1. Since the cross-sectional shape of the second cam portion 38 in the thickness direction is tapered in this way, the second cam portion 38 has a second thick portion 38C and a second thin portion 38D having a smaller dimension in the thickness direction than the second thick portion.

[0046] The key projection 32E is slidably fitted into the key groove 39. Thereby, the cam member 33 is restricted from rotating around the rotation axis CL1 and is slidably attached along the rotation axis CL1.

[0047] With reference to FIGS. 12 and 13, the operations of the restriction operation member 25 and the cam member 33 will be described. When the user wants to restrict the rotation of the dial operation member 24, that is, when the user wants to fix the position of the dial operation member 24, in this embodiment, when the dial operation member 24 is operated to obtain a shutter speed desired by the user, the user operates the restriction operation member 25 in the moving direction R1 to change the dial operation member 24 from the released state to the restricted state. In FIG. 12, in order to make the operations of the restriction operation member 25 and the cam member 33 easier to understand, the illustration of the attachment piece 32 and the rotation amount detection sensor 34 is omitted. The operation member main body 24A, the restriction operation member 25, and the cam member 33 are formed of materials that generate frictional locking on their contact surfaces when pressed against each other. For example, it is preferable that the operation member main body 24A and the restriction operation member 25 are formed of polycarbonate resin, and the cam member 33 is formed of polyoxymethylene resin. However, the material is not limited to this, and any material that generates frictional locking, such as a metal material and a resin material, may be used.

[0048] As described above, by being coupled to the shaft member 31 by screwing and attached to the attachment piece 32, the dial operation member 24 has a constant interval L0 from the attachment surface 32B. The interval L0 is a dimension in the thickness direction, that is, in the direction parallel to the rotation axis CL1.

[0049] As shown in FIGS. 12(A) and 13(A), when the regulation operation member 25 is in the release position, the first thick portion 36C and the second thin portion 38D face each other, and the second thick portion 38C and the first thin portion 36D face each other. For this reason, the dimension L1 in the thickness direction (see FIG. 12(A)) obtained by adding the regulation operation member 25 and the cam member 33 is smaller than the interval L0. Thereby, the regulation operation member 25 is in a state where the pressing against the cam member 33 is released. The cam member 33 separates from the dial operation member 24 when the pressing from the regulation operation member 25 is released. That is, the cam member 33 has a gap D1 with the dial operation member 24 by an amount that the dimension L1 in the thickness direction obtained by adding the regulation operation member 25 and the cam member 33 is smaller than the interval L0. Therefore, the dial operation member 24 is not frictionally locked by the cam member 33 and is rotatable.

[0050] On the other hand, as shown in FIGS. 12(B) and 13(B), when the regulation operation member 25 moves to the regulation position, the first thick portion 36C and the second thick portion 38C come into contact with each other. In this case, the cam member 33 is pressed by the regulation operation member 25 and moves toward the dial operation member 24. That is, by being pressed from the regulation operation member 25 to the dial operation member 24, the first inclined surface 36B and the second inclined surface 38B are engaged.

[0051] When the first thick portion 36C and the second thick portion 38C come into contact with each other, the dimension L2 in the thickness direction (see FIG. 12(B)) obtained by adding the regulation operation member 25 and the cam member 33 becomes equal to or greater than the interval L0 compared to the case where the regulation operation member 25 is in the release position. Thereby, the gap between the cam member 33 and the dial operation member 24 disappears. For this reason, the dial operation member 24 receives the pressing from the regulation operation member 25 via the cam member 33. That is, the dial operation member 24 is frictionally locked by the cam member 33 and is in a regulated state where rotation is regulated.

[0052] Also, when the user wants to release the restriction on the dial operation member 24, the user operates the restriction operation member 25 in the moving direction R2 to change the dial operation member 24 from the restricted state to the released state. As shown in FIGS. 12(A) and 13(A), when the restriction operation member 25 moves to the release position, as described above, the cam member 33 is separated from the dial operation member 24 because the pressing force from the restriction operation member 25 is released. Therefore, the dial operation member 24 is not frictionally locked by the cam member 33 and becomes rotatable.

[0053] As shown in FIG. 14, the lens barrel 12 includes an imaging optical system 22, a focus ring 23, a dial operation member 24, a mode switching operation member 26, etc., and also includes a lens control unit 51, a motor driver 52, a shake detection sensor 53, motors 54 to 57, etc.

[0054] The lens control unit 51 is composed of a microcomputer including a CPU (Central Processing Unit), a ROM (Read Only Memory) storing programs and parameters used by this CPU, and a RAM (Random Access Memory) used as the work memory of the CPU (none of which are shown), and controls each part of the lens barrel 12. The lens control unit 51 is connected to the focus ring 23, the dial operation member 24, the mode switching operation member 26, the motor driver 52, and the shake detection sensor 53.

[0055] The lens control unit 51 controls the aperture unit 58, the focus lens 22a, the zoom lens 22b, and the shake correction lens 22c based on signals from operations of the focus ring 23, the dial operation member 24, the mode switching operation member 26, and a control signal from the camera body control unit 61 described later.

[0056] The imaging optical system 22 includes a plurality of lenses including a focus lens 22a and a zoom lens 22b, a diaphragm unit 58, etc. The focus lens 22a moves in the optical axis direction OA by driving of a motor 54 to adjust the imaging distance. The lens control unit 51 transmits a control signal for moving the focus lens 22a to the motor driver 52 according to the rotation direction and rotation amount of the focus ring 23 detected based on a signal from a rotation amount detection unit (not shown). The motor driver 52 drives the motor 54 based on the control signal.

[0057] The zoom lens 22b moves in the optical axis direction OA by driving of a motor 55 to constitute an electric zoom mechanism for changing the magnification of the imaging angle of view of the imaging optical system 22. In this zoom mechanism, for example, the movement amount and movement direction of the zoom lens 22b are determined according to an operation on the camera body 11 side. By moving the zoom lens 22b, the imaging angle of view of the imaging optical system 22 can be changed.

[0058] The diaphragm unit 58 moves a plurality of diaphragm blades 58a by driving of a motor 56 to change the amount of incident light to the imaging element 16. The shake detection sensor 53 detects the shake direction and shake amount of the lens barrel 12. The shake direction and shake amount detected by the shake detection sensor 53 are output to the lens control unit 51 as a shake detection signal. The lens control unit 51 controls the driving of the motor 57 based on the shake detection signal and corrects the shake by moving the shake correction lens 22c. The motor driver 52 controls the driving of the motors 54 to 57 based on the control of the lens control unit 51.

[0059] The camera body control unit 61 includes a CPU, a ROM storing programs and parameters used by this CPU, a RAM (none of which are shown) used as a work memory of the CPU, etc. The camera body control unit 61 controls the camera body 11 and each part of the lens barrel 12 connected to the camera body 11. A release signal is input to the camera body control unit 61 from the release switch 14. Also, a body side signal contact 17 is connected to the camera body control unit 61.

[0060] The lens-side signal contact 28 contacts the body-side signal contact 17 when the lens mount 27 of the lens barrel 12 is attached to the lens mount 13 of the camera body 11, and electrically connects the lens barrel 12 and the camera body 11.

[0061] The shutter unit 62 is a so-called focal plane shutter and is disposed between the lens mount 13 and the imaging element 16. The shutter unit 62 is provided so as to be able to block the optical path between the imaging optical system 22 and the imaging element 16, and changes between an open state and a closed state. The shutter unit 62 is in the open state during live view image and video shooting. The shutter unit 62 temporarily changes from the open state to the closed state during still image shooting. This shutter unit 62 is driven by a shutter motor 73. The motor driver 63 controls the driving of the shutter motor 73.

[0062] The imaging element 16 is driven and controlled by the camera body control unit 61. The imaging element 16 has a light receiving surface formed by a plurality of pixels (not shown) arranged in a two-dimensional matrix. Each pixel includes a photoelectric conversion element, and photoelectrically converts the subject image formed on the light receiving surface by the lens barrel 12 to generate an imaging signal.

[0063] Further, the imaging element 16 includes signal processing circuits (none of which are shown) such as a noise removal circuit, an auto gain controller, and an A / D conversion circuit. The noise removal circuit performs noise removal processing on the imaging signal. The auto gain controller amplifies the level of the imaging signal to an optimal value. The A / D conversion circuit converts the imaging signal into a digital signal and outputs it from the imaging element 16 to the bus line 65. The output signal of the imaging element 16 is image data (so-called RAW data) having one color signal for each pixel.

[0064] The image memory 64 stores the image data for one frame output to the bus line 65. The image data processing unit 66 reads out the image data for one frame from the image memory 64 and performs known image processing such as matrix operation, demosaicing, gamma correction, luminance / chrominance conversion, and resizing processing.

[0065] The LCD driver 67 sequentially inputs the image data for one frame that has been image-processed by the image data processing unit 66 to the image display unit 68. The image display unit 68 is provided, for example, on the back surface of the camera body 11 and sequentially displays live view images at a constant cycle. The card I / F (Interface) 69 is incorporated in a card slot (not shown) provided in the camera body 11 and is electrically connected to the memory card 71 inserted into the card slot. The card I / F 69 stores the image data that has been image-processed by the image data processing unit 66 in the memory card 71. Also, when reproducing and displaying the image data stored in the memory card 71, the card I / F 69 reads out the image data from the memory card 71.

[0066] The camera body control unit 61 performs control to move the focus lens 22a with respect to the lens control unit 51 according to the information on the rotation direction and rotation amount of the focus ring 23 or the information on the subject distance measured by the autofocus function.

[0067] The camera body control unit 61 operates the aperture unit 58 according to the exposure information calculated by the AE (Automatic Exposure) processing unit 72 described later and transmits a control signal for changing the aperture diameter to the lens control unit 51. The lens control unit 51 controls the motor driver 52 based on the control signal and changes the aperture diameter. The lens control unit 51 controls the motor driver 52 based on the control signal and controls the aperture diameter of the aperture unit 58 so as to obtain the aperture value calculated by the AE processing unit 72.

[0068] The camera body control unit 61 transmits a control signal for varying the shutter speed to the motor driver 63 according to the rotation direction and rotation amount of the dial operation member 24 detected based on the signal from the rotation amount detection sensor 34. The motor driver 63 controls the driving of the shutter motor 73 so that a shutter speed corresponding to the rotation direction and rotation amount of the dial operation member 24 is obtained.

[0069] The AE processing unit 72 calculates the integrated value of each color signal from the image data for one frame. The camera body control unit 61 calculates an appropriate exposure value based on the integrated value calculated for each image for one frame, and determines the aperture value so that it becomes the appropriate exposure value for the shutter speed corresponding to the rotation direction and rotation amount of the dial operation member 24. The camera body control unit 61 transmits a control signal to the lens control unit 51. The lens control unit 51 controls the motor driver 52 based on the control signal, and operates the aperture unit 58 to the aperture diameter at which the determined aperture value is obtained.

[0070] The operation of the digital camera 10 of this embodiment will be described. When the power switch (not shown) is operated by the user who is the imaging person and the power is turned on, a power supply voltage is supplied to each part of the digital camera 10. The user operates the mode switching operation member 26, for example, to switch between the moving image shooting mode and the still image shooting mode.

[0071] The user performs moving image shooting or still image shooting while adjusting the focal length, shutter speed, etc. As described above, when the user operates the dial operation member 24 to obtain a desired shutter speed, the user operates the restriction operation member 25 to put the dial operation member 24 in a restricted state. Thereby, the set value of the shutter speed will not be changed without the user's knowledge.

[0072] As described above, in the present embodiment, since the regulation operation member 25 and the cam member 33 are provided, the dial operation member 24 is brought into a regulated state simply by rotating the regulation operation member 25 from the release position to the regulation position. In this case, while the first inclined surface 36B and the second inclined surface 38B are in contact with each other, they gradually come into an engaged state, and since the dial operation member 24 is brought into a regulated state, the operation sound is small. Further, since the dial operation member 24 is frictionally locked by the cam member 33 and its rotation is restricted, there is no need to lock the operation member with a click mechanism or the like as in a conventional lens barrel. That is, in the lens barrel 12 of the present embodiment, the operation sound when changing the dial operation member 24 from the released state to the regulated state and from the regulated state to the released state is small.

[0073] The fact that the operation sound is small when operating the regulation operation member 25 in this way is particularly effective during video imaging. Also, since it does not have a configuration that uses a push-type button when setting to the regulated state like a conventional lens barrel, even if the regulation operation member 25 is operated during video shooting, the optical axis O of the imaging optical system 22 does not shake, and it is possible to prevent the screen from shaking during video imaging.

[0074] Also, in the lens barrel 12, the regulation mechanism 29 that brings the dial operation member 24 into a regulated state is operated by only a small number of parts, namely the regulation operation member 25 and the cam member 33. For this reason, it is possible to suppress the height at which the parts protrude from the outer peripheral surface 21A, and as a result, it is possible to contribute to the miniaturization of the lens barrel 12 and an improvement in the degree of freedom in design. In particular, compared to a configuration such as that of Patent Document 1 having a structure in which two holding members sandwich a flange portion provided on the operation ring, the dimensions in the thickness direction (the radial direction of the lens barrel) are suppressed.

[0075] Also, the regulation operation member 25 is rotatable about a rotation axis CL1 that intersects the optical axis O of the imaging optical system 22. Therefore, it is possible to prevent an erroneous operation in which the user mistakes the regulation operation member 25 for the focus ring 23 or the like that is rotatably provided around the optical axis O without having to visually confirm.

[0076] In the first embodiment described above, the dial operation member 24 faces the mounting surface 32B that is recessed from the outer peripheral surface 21A and is a rotating member that rotates around the rotation axis CL1 orthogonal to the mounting surface 32B. However, the present invention is not limited to this. As shown in FIG. 15, the dial operation member 24 may face the tangent surface 21B (the surface indicated by the two-dot chain line) that is tangent to the outer peripheral surface 21A of the lens barrel 12 and be a rotating member that rotates within the tangent surface 21B. In this case, it is preferable that the restriction operation member 25 and the cam member 33 are located closer to the inner side in the radial direction of the lens barrel 12 than in the first embodiment.

[0077] [Second Embodiment] In the first embodiment described above, an example of setting a restriction state for the dial operation member 24 rotatably provided around the rotation axis CL1 is shown. However, the present invention is not limited to this. As the operation member, a pressing button that moves forward and backward along the mounting shaft may be set to a restriction state. Note that except for the configuration of the pressing button 81 as the operation member, the restriction mechanism 83, and the switch 88, it is the same as the lens barrel 12 of the first embodiment. For the same components, the same reference numerals are given and the description is omitted.

[0078] The pressing button 81 is an operation member for adjusting the optical function of the imaging optical system 22, similar to the dial operation member 24 of the first embodiment. The pressing button 81 is attached to the attachment piece 82. The attachment piece 82 constitutes a part of the lens barrel main body 21, similar to the attachment piece 32 of the first embodiment.

[0079] The restriction mechanism 83 includes the attachment piece 82, the restriction operation member 25, and the cam member 33. The attachment piece 82 is formed in an arc shape continuous with the outer peripheral surface 21A of the lens barrel main body 21. The attachment piece 82 has a concave portion 82A, a mounting surface 82B, a through hole 82C, a protruding strip portion 82D, and a key protrusion (not shown). The concave portion 82A is a portion recessed with respect to the outer peripheral surface 21A. The restriction operation member 84 is disposed inside the concave portion 82A. The mounting surface 82B is formed inside the concave portion 82A and is a flat surface recessed from the outer peripheral surface 21A.

[0080] The rib portion 82D is formed in an arc shape along the periphery of the mounting surface 82B and protrudes radially outward with respect to the outer peripheral surface 21A. A plurality of key protrusions are provided on the inner peripheral surface of the rib portion 32D. The key protrusions extend in a direction parallel to the mounting shaft 86A described later and fit into the key groove 39 of the cam member 33.

[0081] The pressing button 81 includes a button body 86 and a spring member 87. The button body 86 has a mounting shaft 86A and a pressed portion 86B. The mounting shaft 86A is formed in a columnar shape and fits into the through hole 82C of the mounting piece 82. Thereby, the pressing button 81 moves forward and backward along the mounting shaft 86A that intersects the mounting surface 82B with respect to the lens barrel main body 21. The pressed portion 86B is formed in a disc shape having a larger outer diameter than the mounting shaft 86A and faces the mounting surface 82B.

[0082] The spring member 87 biases the pressing button 81 radially outward of the lens barrel main body 21. The spring member 87 is an outer-fitted coil spring disposed between the mounting shaft 86A and the mounting piece 82. Note that the spring member 87 is not limited thereto, and any member that biases the pressing button 81 may be used, for example, a leaf spring.

[0083] The restricting operation member 25 and the cam member 33 have the same shape as in the first embodiment. The restricting operation member 25 is disposed inside the recess 82A and at a position facing the mounting surface 82B. The restricting operation member 25 is rotatably supported around the mounting shaft 86A. The cam member 33 is provided between the restricting operation member 25 and the pressed portion 86B of the pressing button 81. The rotation of the cam member 33 around the mounting shaft 86A is restricted.

[0084] The base end portion of the mounting shaft 86A faces the switch 88. The switch 88 is, for example, a well-known tact switch that becomes on when pressed and off when the pressing is released. The switch 88 is mounted inside the lens barrel main body 21 via a substrate (not shown).

[0085] When the pressing button 81 is not being pressed, the pressing button 81 is biased radially outward by the spring member 87, so the mounting shaft 86A does not contact the switch 88 (the position shown by the solid line in Fig. 16(A)). Therefore, the switch 88 is in the off state. On the other hand, when the pressing button 81 is being pressed, against the biasing of the spring member 87, the pressing button 81 moves along the mounting shaft 86A, and the mounting shaft 86A contacts the switch 88 (the position shown by the two-dot chain line in Fig. 16(A)). Therefore, the switch 88 is pressed by the pressing button 81 and becomes on state.

[0086] Attached to the attachment piece 82 and biased by the spring member 87, the pressed portion 86B has a constant distance L0 maintained between it and the attachment surface 82B (when the pressing button 81 is not being pressed by the user). The distance L0 is a dimension in the thickness direction, that is, the direction parallel to the rotation axis CL1.

[0087] As shown in Fig. 16(A), when the regulating operation member 25 is in the release position, the first thick portion 36C and the second thin portion 38D face each other, and the second thick portion 38C and the first thin portion 36D face each other. For this reason, the thickness direction dimension L1 of the sum of the regulating operation member 25 and the cam member 33 is smaller than the distance L0. Thereby, the regulating operation member 25 is in a state where the pressing on the cam member 33 is released. The cam member 33 separates from the pressed portion 86B when the pressing from the regulating operation member 25 is released. That is, the cam member 33 has a gap D1 between it and the pressed portion 86B by an amount that the thickness direction dimension L1 of the sum of the regulating operation member 25 and the cam member 33 is smaller than the distance L0. Therefore, the pressing button 81 cannot be frictionally locked by the cam member 33 and can be pressed by the user.

[0088] On the one hand, as shown in FIG. 16(B), when the regulation operation member 25 moves to the regulation position, the first thick portion 36C and the second thick portion 38C come into contact with each other. In this case, the cam member 33 is pressed by the regulation operation member 25 and moves toward the pressing button 81. When the first thick portion 36C and the second thick portion 38C come into contact with each other, the thickness dimension L2 in the thickness direction of the sum of the regulation operation member 25 and the cam member 33 becomes equal to or greater than the interval L0, as compared with the case where the regulation operation member 25 is in the release position. As a result, the gap between the cam member 33 and the pressing button 81 disappears. Therefore, the pressing button 81 is pressed by the regulation operation member 25 via the cam member 33. That is, the pressing button 81 is frictionally locked by the cam member 33 and enters a regulated state where its forward and backward movement is restricted.

[0089] Similar to the first embodiment, by simply rotating the regulation operation member 25 from the release position to the regulation position, the pressing button 81 enters the regulated state, and the operation sound when changing the pressing button 81 from the release state to the regulated state and from the regulated state to the release state is small. That is, the same effect as that of the lens barrel 12 of the first embodiment can be obtained.

[0090] [Third Embodiment] In the first and second embodiments described above, an example is shown in which the regulation operation member 25 (the first member) is provided coaxially with the operation member and is rotatable between the regulation position and the release position. However, the present invention is not limited to this, and the first member may be configured to slide between the release position and the regulation position. Note that, except for the configuration of the pressing button, switch, and regulation mechanism as the operation member, the configuration is the same as that of the first and second embodiments, and the same components are denoted by the same reference numerals and the description thereof is omitted.

[0091] The regulation mechanism 91 includes a mounting piece 92, a regulation operation member 93, and a cam member 94. The regulation mechanism of this embodiment restricts the forward and backward movement of the pressing button 81 to the regulated state. The pressing button 81 has the same configuration as that of the second embodiment.

[0092] Similar to the second embodiment, when the pressing button 81 is not being pressed, the mounting shaft 86A does not contact the switch 88 (the position shown by the solid line in Fig. 17(A)). Therefore, the switch 88 is in the off state. On the other hand, when the pressing button 81 is being pressed, the mounting shaft 86A contacts the switch 88 (the position shown by the two-dot chain line in Fig. 17(A)). Therefore, the switch 88 is pressed by the pressing button 81 and becomes the on state.

[0093] The attachment piece 92 has a recess 92A, an attachment surface 92B, a through hole 92C, and a protrusion 92D. The recess 92A is a portion recessed with respect to the outer peripheral surface 21A. The regulation operation member 93 is disposed inside the recess 92A. The attachment surface 92B is formed inside the recess 92A and is a flat surface recessed from the outer peripheral surface 21A. The protrusion 92D is formed in an arc shape along the periphery of the attachment surface 92B and protrudes radially outward with respect to the outer peripheral surface 21A.

[0094] The regulation operation member 93 has a first cam portion 96 and a finger hook portion 97. When the user operates the regulation operation member 93, the user hooks a finger on the finger hook portion 97 and slides the regulation operation member 93. The first cam portion 96 is slidably supported in a direction intersecting the mounting shaft 86A. That is, in the present embodiment, the moving direction R1 in which the regulation operation member 93 moves from the release position to the regulation position and the moving direction R2 in which the regulation operation member 25 moves from the regulation position to the release position are directions intersecting the mounting shaft 86A. The first cam portion 96 is a rectangular plate shape extending in the moving direction R1.

[0095] The first cam portion 96 has a first inclined surface 96A. The first inclined surface 96A is an inclined surface inclined with respect to the moving direction R1. The first cam portion 36 includes the first inclined surface 96A and has a tapered cross-sectional shape in the thickness direction. More specifically, the portion of the first cam portion 36 including the first inclined surface 96A is tapered such that the dimension in the thickness direction gradually decreases toward the moving direction R1.

[0096] The cam member 94 corresponds to the second member in the claims. The cam member 94 is provided between the regulation operation member 93 and the pressed portion 86B of the pressing button 81. The cam member 94 has a second cam portion 98. The second cam portion 98 is formed in a disc shape or a rectangular plate shape with an outer diameter smaller than that of the pressed portion 86B.

[0097] The second cam portion 98 has a second inclined surface 98A. The second inclined surface 98A is disposed at a position facing the regulation operation member 93 and is an inclined surface inclined with respect to the moving direction R1. The second cam portion 38 includes the second inclined surface 98A and has a tapered cross-sectional shape in the thickness direction. More specifically, the portion of the second cam portion 98 including the second inclined surface 98A has a tapered shape in which the dimension in the thickness direction gradually increases toward the moving direction R1.

[0098] Attached to the attachment piece 92 and biased by the spring member 87, the pressed portion 86B has a constant interval L0 maintained between it and the attachment surface 92B (when the pressing button 81 is not being pressed by the user). The interval L0 is a dimension in the thickness direction, that is, the direction parallel to the rotation axis CL1.

[0099] As shown in FIG. 17(A), when the regulation operation member 93 is in the release position, the dimension L1 in the thickness direction (see FIG. 17(A)) obtained by adding the regulation operation member 93 and the cam member 94 is smaller than the interval L0. As a result, the regulation operation member 93 is in a state where the pressing on the cam member 94 is released. The cam member 94 is separated from the pressed portion 86B when the pressing from the regulation operation member 93 is released. That is, the cam member 94 has a gap D1 between it and the pressed portion 86B by an amount that the dimension L1 in the thickness direction obtained by adding the regulation operation member 93 and the cam member 94 is smaller than the interval L0. Therefore, the pressing button 81 can be pressed without being frictionally locked by the cam member 94.

[0100] On the one hand, as shown in FIG. 17(B), when the regulation operation member 93 moves to the regulation position, the cam member 33 moves toward the side of the pressing button 81 under the pressure from the regulation operation member 25. The dimension L2 (see FIG. 17(B)) in the thickness direction obtained by adding the regulation operation member 93 and the cam member 94 becomes equal to or greater than the interval L0 compared to the case where the regulation operation member 25 is in the release position. As a result, the gap between the cam member 94 and the pressing button 81 disappears. For this reason, the pressing button 81 receives the pressure from the regulation operation member 93 via the cam member 94. That is, the pressing button 81 is frictionally locked by the cam member 94 and enters a regulation state where its forward and backward movement is restricted.

[0101] Similar to the first and second embodiments described above, by simply sliding the regulation operation member 93 from the release position to the regulation position, the pressing button 81 enters the regulation state, and the operation sound when changing the pressing button 81 from the release state to the regulation state and from the regulation state to the release state is small. That is, the same effects as those of the lens barrel 12 of the first and second embodiments can be obtained.

[0102] In the third embodiment described above, an example is shown in which the forward and backward movement of the pressing button 81 as the operation member is restricted by the regulation operation member 93 and the cam member 94 to enter the regulation state. However, the present invention is not limited to this, and a configuration in which the regulation operation member 93 and the cam member 94 are combined with a rotating member such as the dial operation member 24 as the operation member to restrict the rotation of the rotating member to the regulation state may also be used.

[0103] In the second and third embodiments described above, the pressing button 81 faces the mounting surfaces 82B and 92B that are recessed from the outer peripheral surface 21A and moves forward and backward in a direction intersecting the mounting surfaces 82B and 92B. However, the present invention is not limited to this, and the pressing button may face the tangent surface 21B (see FIG. 15) that is tangent to the outer peripheral surface 21A of the lens barrel 12 and move forward and backward in a direction intersecting the tangent surface 21B.

[0104] In each of the above embodiments, as an optical function of the imaging optical system 22 that is adjusted by an operating member such as the dial operating member 24 or the push button 81, changing the shutter speed is exemplified. However, the present invention is not limited to this, and any adjustment related to the optical function of the imaging optical system 22 may be used. For example, it may be any one of the aperture of the imaging optical system 22, the amount of shake correction, and the angle-of-view zoom.

[0105] Also, in each of the above embodiments, an example of adjusting the optical function of the imaging optical system 22 by an operating member such as the dial operating member 24 or the push button 81 is shown. However, the present invention is not limited to this. For example, the lens control unit 51 or the camera body control unit 61 performs control to switch the function executed according to the operation by the operating member. When the lens barrel 12 is attached to the camera body 11, the lens control unit 51 or the camera body control unit 61 may perform control to operate the camera body 11 instead of adjusting the optical function of the imaging optical system 22 according to the operation by the dial operating member 24 or the push button 81. Further, in this case, when the restriction operating members 25 and 93 are operated to put the operating member in a restricted state, it is preferable to perform a release lock state, power on / off switching of the camera body 11, transition to a power sleep mode, and the like.

[0106] In each of the above embodiments, the first member and the second member are tapered to have a thick portion and a thin portion. However, the present invention is not limited to this. At least the first member has portions with different thicknesses in the moving direction, and the minimum value of the sum of the dimensions of the first member and the second member in the thickness direction is smaller than the interval L0, and the maximum value of the sum of the dimensions of the first member and the second member in the thickness direction is equal to or greater than the interval L0. With this configuration, the first member can be set in a restricted state and a released state in the same manner as in each of the above embodiments.

[0107] In each of the above embodiments, the hardware structure of a processing unit that executes various processes such as the lens control unit 51 and the camera body control unit 61 is various processors as shown below. The various processors include a CPU (Central Processing Unit), which is a general-purpose processor that executes software (program) and functions as various processing units, a GPU (Graphical Processing Unit), a PLD (Programmable Logic Device), which is a processor whose circuit configuration can be changed after manufacturing, such as an FPGA (Field Programmable Gate Array), and a dedicated electric circuit, which is a processor having a circuit configuration designed specifically for executing various processes.

[0108] One processing unit may be configured by one of these various processors, or may be configured by a combination of two or more processors of the same type or different types (for example, a plurality of FPGAs, a combination of a CPU and an FPGA, or a combination of a CPU and a GPU, etc.). Also, a plurality of processing units may be configured by one processor. Examples of configuring a plurality of processing units by one processor include, firstly, a form in which one processor is configured by a combination of one or more CPUs and software, as represented by a computer such as a client or a server, and this processor functions as a plurality of processing units. Secondly, there is a form in which a processor that realizes the functions of an entire system including a plurality of processing units with one IC (Integrated Circuit) chip, as represented by an SoC (System On Chip). Thus, the various processing units are configured by using one or more of the above various processors as a hardware structure.

[0109] Furthermore, the hardware structure of these various processors is more specifically an electric circuit (circuitry) in a form that combines circuit elements such as semiconductor elements.

[0110] Note that the present invention is applicable not only to digital cameras but also to imaging devices such as smartphones and video cameras.
