DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is applicable to various electronic devices having an eyepiece member in a viewfinder. In the embodiment, an example of an image pickup device having an eyecup in a viewfinder eyepiece is shown as an electronic device.

[0010] [First Example] With reference to Figs. 1 and 2, an interchangeable lens digital camera (hereinafter, simply referred to as camera) 10 will be described as an imaging device of this embodiment. Fig. 1 shows a main body 100 with no interchangeable lens unit attached. The subject side is defined as the front side, and the positional relationship of each part will be described. Fig. 1(A) is a perspective view of the camera 10 as viewed from the front side, and Fig. 1(B) is a perspective view of the camera 10 as viewed from the rear side. The optical axis direction of the camera 10 is defined as the Z direction, and two directions perpendicular to the Z direction are defined as the X direction and the Y direction, respectively. The left-right direction is defined as the X direction, and the up-down direction is defined as the Y direction. Fig. 2 is a block diagram showing the functional configuration of the camera 10.

[0011] Grip section 120 is a gripping section for the user to hold camera 10. Grip section 120 is provided at one end of main body section 100, and is formed with a curved shape so that the user can hold it by covering it with the palm of their hand and hook their fingers on it. By forming the surface of grip section 120 from an elastic material such as synthetic rubber, good gripping properties can be obtained.

[0012] Camera 10 is configured so that lens unit 50 (see FIG. 2) can be attached and detached to and from mount opening 60 on the front side by pressing lens attachment / detachment button 61. Lens unit 50 constitutes an imaging optical system, and includes focus lens 51a and zoom lens 51b, which are made up of a group of multiple lenses. Lens unit 50 includes diaphragm 52 that adjusts the aperture size. Lens drive mechanism 53 drives focus lens 51a and zoom lens 51b to perform focusing and zoom drive. Aperture drive mechanism 54 drives diaphragm 52 and controls the aperture value. Lens CPU (Central Processing Unit) 55 performs various signal processing and controls each part within lens unit 50.

[0013] The main body 100 and the lens unit 50 are electrically connected and can communicate with each other via a camera side communication I / F (interface) unit 62 and a lens side communication I / F unit 56. In addition, power is supplied from the main body 100 to the lens unit 50.

[0014] The camera CPU 40 is a central part that controls the imaging system, and controls the operation of each element of the camera 10. Hereinafter, the camera CPU 40 will be simply referred to as CPU 40. The lens detection switch 63 of the main body 100 outputs a detection signal to the CPU 40 for determining whether the main body 100 and the lens unit 50 are capable of communicating with each other via the camera side communication I / F unit 62 and the lens side communication I / F unit 56. The lens detection switch 63 also outputs a signal to the CPU 40 for identifying the type of the lens unit 50 attached to the main body 100.

[0015] A power source 65 supplies power to each element of the camera 10. The power source 65 is formed of a battery pack or the like that is detachable from the main body 100. A power supply circuit 66 converts the voltage of the power source 65 into a voltage required for the operation of each element of the camera 10 and supplies it to the circuit section.

[0016] The shutter 80 is a focal plane shutter that is driven by a shutter drive circuit 81 and controls the incidence of imaging light beams by exposing and blocking the image sensor 71. The shutter drive circuit 81 opens and closes a shutter curtain (not shown) to enable the image sensor 71 to transition to and maintain an exposed state (open state) or a blocked state (closed state).

[0017] The imaging element 71 performs photoelectric conversion by taking in a photographing light beam from the lens unit 50. For example, the imaging element 71 uses a CMOS (complementary metal-oxide semiconductor) image sensor or a CCD (charge-coupled device) image sensor, and has an electronic shutter function.

[0018] The optical low pass filter 75 arranged on the front side of the image sensor 71 is a rectangular optical element made of a material such as quartz. The piezoelectric element 76 is adhesively held on the surface of the optical low pass filter 75, and a piezoelectric element drive circuit 77 energizes the piezoelectric element 76. The piezoelectric element drive circuit 77 is electrically connected to the piezoelectric element 76 via a flexible piezoelectric element substrate (not shown). By controlling the energization of the piezoelectric element 76, the optical low pass filter 75 is vibrated in the Z direction in a plurality of vibration modes of different orders, making it possible to remove dust adhering to the surface of the optical low pass filter 75.

[0019] The shake detection sensor 78 is, for example, an angular velocity sensor, which periodically detects the angular velocity of the shake of the camera 10 and converts it into an electrical signal. The output of the shake detection sensor 78 is obtained by the CPU 40 as a detection signal of the amount of shake of the camera 10.

[0020] The imaging unit 70 includes an imaging element 71, an optical low-pass filter 75, a piezoelectric element 76, and an imaging unit drive mechanism 72. The imaging unit drive mechanism 72 is a mechanism that drives the imaging element 71 within a predetermined plane, and is provided with, for example, a drive coil, a permanent magnet, and a position detection sensor (none of which are shown) for driving the imaging element 71 on a plane perpendicular to the optical axis of the camera 10.

[0021] The imaging unit drive circuit 73 is electrically connected to the imaging unit drive mechanism 72 via a flexible substrate for the imaging unit drive mechanism (not shown), and controls the current supply to the imaging unit drive mechanism 72. The CPU 40 acquires a detection signal from the shake detection sensor 78, and controls the drive of the imaging unit 70 in a direction that cancels the shake of the camera 10 according to the detection result. This makes it possible to correct image blur caused by the shake of the camera 10.

[0022] The external memory 67 is, for example, a semiconductor memory card that is detachable from the main body 100, and stores data such as captured images. The operation members 110 are members that allow the user to issue operational instructions to the camera 10. The CPU 40 accepts instruction signals from the various operation members 110 and performs various controls. For example, FIG. 1(A) shows a shutter button 111 that issues instructions for a photographing operation, and FIG. 1(B) shows a selection button 114 that selects various settings and a setting button 115 that determines various settings.

[0023] Camera 10 includes first display 200 and second display 210. As shown in Fig. 1(B), first display 200 is provided on the rear surface of camera 10. First display 200 is configured with an LCD (liquid crystal display device) or the like, and a viewfinder 85 is provided on the upper side (+Y side) thereof so that the user can observe the subject.

[0024] The finder 85 is an electronic viewfinder having an eyepiece optical system 86 provided in the upper left corner of the back surface of the camera 10. The second display 210 constitutes a display unit of the electronic viewfinder. The finder 85 displays a through image captured by the imaging element 71 and displays settings of the camera 10.

[0025] The diopter adjustment dial 87 (see FIG. 1(B)) is a diopter adjustment member that can be operated by the user, and is provided on the exterior of the main body 100. The diopter adjustment dial 87 is connected to the eyepiece optical system 86. By rotating the diopter adjustment dial 87, the eyepiece optical system 86 advances and retreats in the Z direction. The user can adjust the diopter to suit their own eyes.

[0026] An eyecup unit 300 is attached to the viewfinder 85. There are two embodiments in which the eyecup unit 300 is configured to be detachable from the main body 100 of the camera 10, and another embodiment in which the eyecup unit 300 is configured to be fixed to the main body 100.

[0027] The viewfinder 85 protrudes from the main body 100 toward the rear side (-Z side). When the user views the main body 100 of the camera 10 from the rear side, the viewfinder 85 is located above the first display 200 when the user holds the grip part 120 with the right hand and holds the camera 10.

[0028] Next, the eyecup unit 300 in this embodiment will be described in detail with reference to Figures 3 and 4. Figure 3(A) is an exploded perspective view of the camera 10 and the eyecup unit 300 as viewed from the rear side. Figure 3(B) is an exploded perspective view of the eyecup unit 300 as viewed from the front side.

[0029] The eyecup unit 300 is composed of an eyecup 310, a base member 320, and a cover member 330. The eyecup 310 is a member that comes into contact with the face (around the eyes) when the user looks through the viewfinder 85, and is made of a soft material such as silicone or rubber. The base member 320 is a member that holds the eyecup 310, and is attached or fixed to the viewfinder 85. The cover member 330 is a member that has an eyepiece window. The base member 320 and the cover member 330 are made of a hard material such as PC (polycarbonate) resin or ABS (Acrylonitrile Butadiene Styrene) resin.

[0030] The hollow eyepiece region 310a of the eyecup 310 is an area that comes into contact with the photographer's face when the photographer looks through the viewfinder 85. The eyecup 310 has a first holding region 310b and a second holding region 310c. The first holding region 310b is an area that extends on the outer periphery side of the eyepiece region 310a with respect to the viewfinder 85, and has a plurality of holes formed therein. Hereinafter, these holes will be referred to as a first hole group 310d. The second holding region 310c is an area that extends on the inner periphery side of the eyepiece region 310a with respect to the viewfinder 85, and has a plurality of holes formed therein. Hereinafter, these holes will be referred to as a second hole group 310e.

[0031] The base member 320 is formed with a first projection group 320a, a second projection group 320b, and an engaged portion 320c. The first projection group 320a is made up of a plurality of projections that protrude to the front side (+Z side) and engage with the first hole group 310d. The second projection group 320b is made up of a plurality of projections that protrude to the rear side (-Z side) and engage with the second hole group 310e. An engaging portion 330b of the cover member 330, which will be described later, engages with the engaged portion 320c.

[0032] An eyepiece window 330a through which the photographer looks through the viewfinder 85 is formed in a portion of the cover member 330 exposed to the outside. An engagement portion 330b is formed in the cover member 330 at a position corresponding to the engagement portion 320c of the base member 320. The engagement portion 330b of the cover member 330 engages with the base member 320 and the engagement portion 320c, whereby the eyecup 310 is supported in a state in which it is sandwiched between the cover member 330 and the base member 320.

[0033] Figures 4(A) to 4(C) are views of eyecup unit 300 viewed from different directions. Figure 4(A) is a view of eyecup unit 300 viewed from the front side, Figure 4(B) is a side view, and Figure 4(C) is a view of eyecup unit 300 viewed from the rear side. Figures 4(D) and 4(E) show a state in which eyecup unit 300 of Figure 4(A) is attached to camera 10. Figure 4(D) is a cross-sectional view taken along line AA shown in Figure 4(A), and Figure 4(E) is a cross-sectional view taken along line BB shown in Figure 4(A).

[0034] As shown in FIG. 4(D), the protrusions constituting the first protrusion group 320a of the base member 320 are fitted into the holes constituting the first hole group 310d of the eyecup 310. The first protrusion group 320a is further fitted into the groove portion 130 provided in the camera 10. The first hole group 310d (and the first protrusion group 320a) are located in the XZ plane close to the eyepiece area 310a indicated by the dotted line. That is, the first hole group 310d of the eyecup 310 is provided in a position included in a range including the eyepiece area 310a on the projection plane perpendicular to the optical axis of the finder 85. The second protrusion group 320b provided on the base member 320 is loosely fitted into the second hole group 310e of the eyecup 310.

[0035] 4(E), engaging portion 330b of cover member 330 engages with engaged portion 320c of base member 320, whereby cover member 330 is supported by base member 320. When eyecup unit 300 is attached to main body 100, engaging portion 330b faces a side surface of restriction portion 131 of main body 100.

[0036] When engaged portion 320c of base member 320 and engaging portion 330b of cover member 330 are engaged with each other, eyecup 310 is clamped at first holding area 310b and second holding area 310c, respectively, and its movement is restricted.

[0037] As shown in Fig. 4(A), the first hole group 310d and the first protrusion group 320a are not provided at the corners (parts f and g shown by dotted lines) on the upper side (+Y side) of the eyecup unit 300. In addition, at least one protrusion (320a-2 in Fig. 4(A)) of the first protrusion group 320a is disposed substantially coaxially with the diopter adjustment dial 87. This makes it possible to reduce the concentration of stress on one hole of the first hole group 310d in response to an external impact on the eyecup 310, and provides the effect of preventing or suppressing the eyecup 310 from coming off.

[0038] In this embodiment, first projection group 320a of base member 320 protruding toward viewfinder 85 (main body side) functions as an anchor to prevent or suppress deformation of the hollow eyepiece area of ​​eyecup 310 toward the outer periphery. Second projection group 320b of base member 320 protruding toward cover member 330 functions as an anchor to prevent or suppress deformation of the hollow eyepiece area of ​​eyecup 310 toward the inner periphery.

[0039] According to this embodiment, it is possible to realize a configuration in which eyecup 310, which is a component of the eyepiece member, is unlikely to come off while enabling space saving. In addition, first holding area 310b and second holding area 310c of eyecup 310 are not visible from the outside of camera 10, which contributes to improving the appearance.

[0040] [Modification of the first embodiment] In the first embodiment, second projection group 320b is formed on base member 320, but in the first modified example, a projection group corresponding to second projection group 320b is formed on cover member 330. That is, the projection group of cover member 330 and second hole group 310e of eyecup 310 fit together.

[0041] Furthermore, in the first embodiment, second hole group 310e is formed in eyecup 310, but in the second modified example, the second hole group is formed in cover member 330. In this case, base member 320 or eyecup 310 is formed with a group of protrusions that fit into the second hole group.

[0042] In the third modification, a plurality of protrusion groups corresponding to the first protrusion group 320a and the second protrusion group 320b are formed on the eyecup 310. A plurality of hole groups corresponding to the first hole group 310d and the second hole group 310e are formed on the base member 320.

[0043] [Second Example] A second embodiment of the present invention will be described with reference to Fig. 5. In this embodiment, a configuration that enables both a good tactile feel and improved reliability to be achieved for eyecup unit 300 is shown. Note that a description of the same matters as in the first embodiment will be omitted, and the difference will be described in detail with respect to the shape of hollow eyepiece area 310a in eyecup unit 300.

[0044] Fig. 5(A) is a diagram of eyecup unit 300 as viewed from the rear side. Fig. 5(B) is a cross-sectional view taken along line CC in Fig. 5(A). Fig. 5(B) shows only one side of eyecup unit 300. In the illustrated X direction, the +X side is the side approaching the optical axis of finder 85, and the -X side is the side away from the optical axis of finder 85. In the Z direction, the +Z side is the subject side, and the -Z side is the photographer side or rear side.

[0045] Eyepiece area 310a is an area including the part that the photographer touches when looking through viewfinder 85, and has a shape that curves toward the -Z side on the way from the +X side to the -X side. This shape ensures light blocking properties, and the adoption of a hollow structure ensures a good tactile feel.

[0046] A plurality of thickness change points are provided on the inner surface side (the side not visible from the outside) of the eyepiece area 310a. A thickness change point is a point where the thickness (thickness) of a portion of the eyecup 310 extending from the +X side to the -X side changes. When viewed from the Y direction, as shown by the dotted circular frame in Fig. 5(B), a first thickness change point 401 is provided from the +X side to the -Z side, and a second thickness change point 402 is provided from the -Z side to the -X side. Furthermore, a third thickness change point 403 is provided between the first thickness change point 401 and the second thickness change point 402.

[0047] The eyecup 310 has, in order from the +X side, a first thick portion 411, a second thick portion 412, a third thick portion 413, and a fourth thick portion 414. The thick portion that changes from the first thick portion 411 on the +X side at a first thickness change point 401 is the second thick portion 412. The thick portion that changes from the second thick portion 412 at a third thickness change point 403 is the third thick portion 413. The thick portion that changes from the third thick portion 413 at a second thickness change point 402 is the fourth thick portion 414. That is, in this embodiment, by providing three thickness change points 401, 402, and 403 when viewed from the Y direction, it is possible to divide the eyecup 310 into four types of thick portions.

[0048] These four types of thick portions will be described in detail. The thickness (denoted as d2) of the second thick portion 412 is set to be equal to or smaller than the thickness (denoted as d1) of the first thick portion 411. The thickness (denoted as d3) of the third thick portion 413 is set to be smaller than the thickness (denoted as d4) of the fourth thick portion 414. That is, in this embodiment, the following inequality condition is satisfied. Condition 1: d1 ≧ d2. Condition 2: d3 < d4. In this manner, a bent portion is formed based on the first thickness change point 401 and the second thickness change point 402 .

[0049] In this embodiment, the first thickness change point 401 and the second thickness change point 402 are set to be at approximately the same height (distance in the Z direction) from the base member 320 so that the shooting posture is parallel to the subject. By doing so, even if the user looks through the viewfinder 85 with a predetermined or greater force being applied to it when placing the eyepiece close to the viewfinder, the hollow eyepiece region 310a will bend and deform with the first thickness change point 401 and the second thickness change point 402 as fulcrums.

[0050] Furthermore, the base member 320 is provided with a protruding portion 420 so as to be closely surrounded by the hollow eyepiece region 310a. The protruding portion 420 is a portion that protrudes from the base member 320 to the -Z side. The first thickness change point 401 and the second thickness change point 402 are both provided at a position further back (-Z side) than the rear end portion of the protruding portion 420 (the convex portion that protrudes most toward the rear side).

[0051] With the above configuration, the user can maintain a comfortable shooting state when putting the eyepiece close to the lens without feeling any discomfort caused by contact with the protruding portion 420. The protruding portion 420 serves to prevent lateral deviation from occurring when a force is applied to the eyepiece area 310a from the +X side to the -X side. If there is no possibility of lateral deviation, there is no need to provide the protruding portion 420.

[0052] Next, a description will be given of the third thickness change point 403. The second thick portion 412 and the third thick portion 413 are separated by the third thickness change point 403. In this embodiment, the following inequality condition is satisfied. Condition 3: d2 > d3.

[0053] Further, second thick portion 412 is provided to extend to the -X side beyond the Z-direction projection of the rear end (the convex portion that protrudes most toward the rear side) of protrusion 420 provided on base member 320. Furthermore, the tip of protrusion 420 on the -X side has no corners and is rounded. For example, assume that the user drops camera 10 from the rear side. Even if second thick portion 412 comes into contact with protrusion 420 and is crushed, damage to eyecup 310 can be prevented or suppressed, and therefore eyecup 310 with higher reliability can be realized.

[0054] The hollow eyepiece region 310a is configured to have a shape that is inclined from the +X side to the -X side, that is, from the inside to the outside. Even if the first thickness change point 401 and the second thickness change point 402 are provided, the hollow eyepiece region 310a will be inclined toward the -X side (outside) when the eye is placed. The user can take pictures comfortably without having their field of vision obstructed.

[0055] Although the present invention has been described in detail based on the preferred embodiments, the present invention is not limited to the above-mentioned embodiments, and various forms that do not deviate from the gist of the present invention are also included in the technical scope of the present invention. The above-mentioned embodiments can also be combined appropriately.

[0056] For example, in this embodiment, the first thickness change point 401, the second thickness change point 402, and the third thickness change point 403 are provided on the inner surface side of the eyepiece area 310a, that is, on the side not exposed to the outside. However, the present invention is not limited to this, and the effects are the same as those of this embodiment even in an embodiment in which the thickness change points are provided on the outside side of the eyepiece area 310a. The present invention can also be applied to an optical finder.

[0057] According to the above embodiment, it is possible to provide an imaging device equipped with a viewfinder that is capable of fixing the eyecup without using adhesives or the like, is effective in saving space, and is more reliable as the eyecup is less likely to come off.
