[0009] The lens device according to the present embodiment will be described in detail below with reference to the accompanying drawings. Note that the drawings may be drawn at a scale different from the actual scale in order to facilitate understanding of the present embodiment.

[0010] This embodiment relates to a lens device that electrically moves a macro lens group in a direction parallel to the optical axis, and an imaging device that includes the lens device and performs macro photography. 2. Description of the Related Art Conventionally, a lens device is known in which a macro lens group is moved in a direction parallel to an optical axis in order to perform macro photography in an imaging device mounted thereon.

[0011] In such imaging devices, a configuration in which macro photography is performed by manually operating a macro ring provided on a lens device is widely used, while a configuration in which macro photography is performed by moving a macro lens group by electrically operating it has also been proposed. For example, a lens device has been proposed that has a configuration in which a detachable drive unit is connected to a gear unit provided on the outer periphery of a manually operable macro ring, and the macro ring is electrically operated by remotely operating the drive unit.

[0012] Furthermore, for example, a lens device has been proposed that has a configuration in which a ring provided with a gear is attached to a macro ring, and the gear is operated by a remotely controllable driving unit, thereby electrically operating the macro ring. However, in such lens devices that have been proposed in the past, a configuration is adopted in which a gear provided on a macro ring for manual operation is engaged with a gear in a drive unit to perform electrical operation. Therefore, it is difficult for the user to operate the macro ring while holding the lens device directly.

[0013] In addition, the lens device body does not have an operating unit for performing macro photography, and a remote control unit must be connected to perform macro photography, which may limit the shooting modes. Therefore, an object of this embodiment is to provide a lens device that improves the operability of powered macro photography.

[0014] FIG. 1 is a schematic cross-sectional view of an imaging device 1 equipped with a lens device 100 according to this embodiment. As shown in FIG. 1, a lens device 100 according to this embodiment comprises a lens unit 101 and a drive unit 102, and is attached to a camera 200 in an imaging device 1 via a lens mount (not shown). The camera 200 has an imaging surface 201 on which light is collected (guided) by the lens device 100 according to this embodiment, and is provided with an imaging element that captures an image formed by the lens device 100 according to this embodiment.

[0015] The lens unit 101 includes, in order from the object side to the image side, a focus lens group 110, a zoom lens group 120, an extender lens group 130, and a relay lens group 140 (macro lens group). The focus lens group 110 and the zoom lens group 120 move along a direction parallel to the optical axis O for focusing and zooming, respectively.

[0016] The extender lens group 130 moves along a direction perpendicular to the optical axis O so as to be inserted into or removed from the optical path in order to adjust the focal length, for example. The relay lens group 140 moves in a direction parallel to the optical axis O in order to adjust the flange focal length of the camera 200 and to perform macro photography.

[0017] Here, macro photography means photography of an object at a distance closer than the minimum object distance (MOD) of the lens apparatus 100 according to this embodiment when the relay lens group 140 is fixed at the reference position. The reference position of the relay lens group 140 is the position of the relay lens group 140 at which the flange focal length is adjusted in non-macro photography, which is not macro photography, for example. In other words, the reference position of the relay lens group 140 is a position where the relay lens group 140 is positioned so that the focus on the imaging surface 201 does not shift more than the allowable amount even if the zoom lens group 120 is moved in a direction parallel to the optical axis O, for example, in non-macro photography.

[0018] The driving unit 102 includes a focus driving unit 111 , a focus detection unit 112 , a zoom driving unit 121 , a zoom detection unit 122 , a macro driving unit 141 , a macro detection unit 142 , a macro operation unit 150 , and a control unit 160 . The focus driving unit 111 is configured to move the focus lens group 110 , and the focus detection unit 112 is configured to detect the position of the focus lens group 110 .

[0019] Furthermore, the zoom driving unit 121 is configured to move the zoom lens group 120 , and the zoom detection unit 122 is configured to detect the position of the zoom lens group 120 . Furthermore, the macro driving unit 141 is configured to move the relay lens group 140 , and the macro detecting unit 142 is configured to detect the position of the relay lens group 140 .

[0020] As will be described in detail later, the macro operation unit 150 has an input unit for inputting command values ​​for moving the relay lens group 140 to the control unit 160, and a setting unit for setting the command values, and is formed integrally with the lens unit 101. Specifically, the macro operation unit 150 has a box-like shape that is coupled to the housing of the lens unit 101, in other words, that is provided on the housing. The control unit 160 is configured to control the above-mentioned driving units and detecting units by connecting to them.

[0021] FIG. 2 shows a schematic front view of the macro operation unit 150 provided in the lens device 100 according to this embodiment. As shown in FIG. 2, the macro operation section 150 is provided with a macro switch 151 and a volume knob 152a (setting section) as a macro position command section.

[0022] The macro switch 151 has a configuration for switching the relay lens group 140 between an OFF state and an ON state. In the lens device 100 according to this embodiment, when the macro switch 151 is switched to the upper side, the relay lens group 140 is turned on, whereas when the macro switch 151 is switched to the lower side, the relay lens group 140 is turned off. The OFF and ON states of the relay lens group 140 will be described later.

[0023] The volume knob 152a is configured so that, by rotating it, it is possible to change (set) the setting position (movement position, placement position) of the relay lens group 140 in the ON state, in other words, the command value (setting value) indicating the amount of movement from the reference position to the setting position. Furthermore, the volume knob 152a is formed with a mark 152b for indicating the rotation position of the volume knob 152a.

[0024] Furthermore, the display surface 153 of the macro operation unit 150 is provided with an ON display and an OFF display that indicate the position of the macro switch 151, and an arc-shaped display that indicates the operation direction (rotation direction) of the volume knob 152a. The volume knob 152a is provided with a click (not shown) at the phase of the volume knob 152a when the mark 152b is positioned near the OFF display on the display surface 153 (hereinafter, sometimes referred to as the OFF phase). In other words, the click is set so as to be closer to an OFF display than to an ON display on the display surface 153. The click can be formed by a predetermined mechanism (click mechanism) intended to give the user a clicking sensation.

[0025] That is, in the lens device 100 according to this embodiment, the mark 152b is positioned near the OFF display on the display surface 153 when the command value from the volume knob 152a reaches the minimum value. Then, by rotating the volume knob 152a from the OFF display to the ON display on the display surface 153, the command value by the volume knob 152a increases.

[0026] FIG. 3(a) shows a schematic front view of the macro operation unit 150 when the macro switch 151 is switched so that the relay lens group 140 is in the OFF state and the volume knob 152a is in the OFF phase. FIG. 3(b) shows a schematic enlarged cross-sectional view of the vicinity of the relay lens group 140 of the imaging device 1 when the macro operation unit 150 is in the state shown in FIG. 3(a).

[0027] As shown in FIG. 3(a), when a command is issued by the macro switch 151, the relay lens group 140 is turned off. Specifically, as shown in FIG. 3(b), the relay lens group 140 is placed at a reference position where the flange focal length has been adjusted in advance. Here, the distance A is defined as the distance between the lens surface of the relay lens group 140 closest to the image side in the direction parallel to the optical axis O when the relay lens group 140 is in the OFF state and the imaging surface 201 of the imaging element.

[0028] FIG. 4(a) shows a schematic front view of the macro operation unit 150 when the macro switch 151 is switched so that the relay lens group 140 is in the ON state and the volume knob 152a is in the OFF phase. FIG. 4(b) shows a schematic enlarged cross-sectional view of the vicinity of relay lens group 140 of image capture device 1 when macro operation unit 150 is in the state shown in FIG. 4(a).

[0029] As shown in FIG. 4(a), when a command is issued by the macro switch 151, the relay lens group 140 is turned on. On the other hand, the volume knob 152a is in the OFF phase, that is, the command value from the volume knob 152a is at the minimum value. In this case, as shown in FIG. 4(b), the relay lens group 140 is positioned at a reference position where the flange back has been adjusted in advance, i.e., so that the distance between the lens surface of the relay lens group 140 closest to the image side in the direction parallel to the optical axis O and the imaging surface 201 of the imaging element is A. That is, when the command value from the volume knob 152a is the minimum value, the amount of movement of the relay lens group 140 from the reference position is set to zero.

[0030] FIG. 5(a) shows a schematic front view of the macro operation unit 150 when the macro switch 151 is switched so that the relay lens group 140 is in the ON state and the volume knob 152a is in the ON region. FIG. 5(b) shows a schematic enlarged cross-sectional view of the vicinity of relay lens group 140 of image capture device 1 when macro operation unit 150 is in the state shown in FIG. 5(a).

[0031] In this case, the relay lens group 140 is placed at a position shifted in the direction of the arrow X in a direction parallel to the optical axis O from a reference position where the flange focal length has been adjusted in advance. Here, the distance between the lens surface of the relay lens group 140 closest to the image side and the imaging surface 201 of the imaging element when the relay lens group 140 is disposed at the shifted position is defined as B.

[0032] That is, the size of the interval B can be changed according to the rotation position of the volume knob 152a. Then, in the imaging device 1, macro photography is performed with the relay lens group 140 positioned at the shifted position.

[0033] FIG. 6(a) shows a schematic front view of the macro operation unit 150 when the macro switch 151 is switched so that the relay lens group 140 is in the OFF state, and the volume knob 152a is in the ON region. FIG. 6(b) shows a schematic enlarged cross-sectional view of the vicinity of relay lens group 140 of image capture device 1 when macro operation unit 150 is in the state shown in FIG. 6(a).

[0034] In this case, in the lens device 100 according to this embodiment, the command from the macro switch 151 takes priority over the command from the volume knob 152a. That is, since priority is given to the relay lens group 140 being in the OFF state, the relay lens group 140 is placed at a reference position where the flange focal distance has been adjusted in advance.

[0035] In other words, when the macro switch 151 is switched in the macro operation unit 150 to change from the state shown in FIG. 5(a) to the state shown in FIG. 6(a), the relay lens group 140 moves in the direction of arrow Y in a direction parallel to the optical axis O, as shown in FIG. 6(b). Then, when the distance between the lens surface of the relay lens group 140 closest to the image side and the imaging surface 201 of the imaging element changes from B to A, the lens stops.

[0036] Conversely, when the macro switch 151 is switched in the macro operation unit 150 to change from the state shown in FIG. 6(a) to the state shown in FIG. 5(a), the relay lens group 140 moves in the direction of the arrow X in a direction parallel to the optical axis O, as shown in FIG. 5(b). Then, when the distance between the lens surface of the relay lens group 140 closest to the image side and the imaging surface 201 of the imaging element changes from A to B, the lens stops.

[0037] As described above, in the macro operation unit 150, by turning on the macro switch 151, a command to move the relay lens group 140 to a predetermined position set by the volume knob 152a is input to the control unit 160. On the other hand, by turning off the macro switch 151, a command to move the relay lens group 140 to the reference position is input to the control unit 160. In addition, a command value corresponding to the amount of movement of the relay lens group 140 is set to zero within a predetermined range including one end of the rotation range of the volume knob 152a, and a click is provided at a predetermined position within the predetermined range.

[0038] FIG. 7 shows a schematic side view of the housing 105 provided in the lens device 100 according to this embodiment. In the lens device 100 according to this embodiment, the focus lens group 110, the zoom lens group 120, the extender lens group 130, and the relay lens group 140 are housed in a housing 105.

[0039] As shown in FIG. 7, on the housing 105, a focus operation unit 113, a zoom operation unit 123, and an aperture operation unit 170 are provided in this order from the object side to the image side. For example, the focus lens group 110 and the zoom lens group 120 can be moved in a direction parallel to the optical axis O by manually operating the focus operation unit 113 and the zoom operation unit 123, respectively. Furthermore, for example, by manually operating the aperture operation unit 170, the aperture diameter of the aperture diaphragm (not shown) can be changed.

[0040] In addition, the part of the housing 105 in which the extender lens group 130 is housed, i.e., the extender housing 131, is arranged between the aperture operation unit 170 and the lens mount 180, and the macro operation unit 150 is arranged integrally with the extender housing 131. Specifically, in the lens device 100 according to this embodiment, the macro operation unit 150 is disposed below the extender housing 131 as shown in FIG.

[0041] As described above, by providing the macro operation unit 150 in the lens device 100 of this embodiment itself, it is possible to electrically operate the relay lens group 140 in the lens device 100 of this embodiment without providing a separate operating means externally, etc. The macro operation unit 150 is provided with a macro switch 151 and a volume knob 152a, and commands from the macro switch 151 take priority over commands from the volume knob 152a. This allows the relay lens group 140 to be repeatedly moved to the position indicated by the volume knob 152a.

[0042] FIG. 8 is a schematic diagram showing an example of use of the imaging device 1 equipped with the lens device 100 according to this embodiment. As described above, in the lens device 100 according to this embodiment, a click is provided in the phase of the volume knob 152a when the mark 152b is positioned near the OFF display on the display surface 153. Therefore, even if the user of the imaging device 1 cannot see the macro operation unit 150 as shown in Figure 8, the click allows the user to recognize that the command value from the volume knob 152a is at its minimum value.

[0043] Furthermore, in the lens device 100 according to this embodiment, the macro operation unit 150 is disposed below the extender housing 131 as described above. This prevents the macro operation unit 150 from obstructing the user's field of view, making it possible to provide the macro operation unit 150 in the lens device 100 of this embodiment while suppressing a decrease in the operability of the lens device 100 of this embodiment.

[0044] In addition, in the lens device 100 according to this embodiment, the movement trajectory caused by the operation of the macro switch 151 and at least a portion of the movement trajectory of the mark 152b caused by the operation of the volume knob 152a are in the same direction and are approximately parallel to each other. In other words, the movement trajectory when moving the macro switch 151 from the OFF position to the ON position and the movement trajectory when starting to rotate the volume knob 152a from the click position are in the same direction and are approximately parallel to each other.

[0045] The macro switch 151 and the volume knob 152a are arranged on opposite sides of a cross section perpendicular to the display surface 153, the cross section including the center of the ON display and the center of the OFF display on the display surface 153, respectively. In addition, when volume knob 152a is started to be rotated from the click toward the ON display on display surface 153 in a cross section perpendicular to display surface 153, including the center of the OFF display on display surface 153 and the click, the command value by volume knob 152a starts to increase.

[0046] This allows the macro switch 151 and the volume knob 152a to have the same display, making it possible to reduce the size of the macro operation unit 150. That is, in the lens device 100 according to this embodiment, it is possible to arrange such a miniaturized macro operation unit 150 in a limited space.

[0047] FIG. 9 is a schematic cross-sectional view of a portion of the lens device 100 according to this embodiment. As shown in FIG. 9, in the lens device 100 according to this embodiment, the end of the macro operation unit 150 that is farthest from the optical axis O in the direction H perpendicular to the optical axis O in the horizontal plane is the top surface of the volume knob 152a. The distance between the top surface and a cross section that includes the optical axis O and is perpendicular to the direction H is defined as C.

[0048] Furthermore, the distance between the maximum value of the end farthest from the optical axis O in the direction H of each operation unit other than the macro operation unit 150 (in the lens device 100 of this embodiment, this end of the operation lever 132 of the extender lens group 130) and the cross section is defined as D. At this time, the distance C is smaller than the distance D in the lens device 100 according to this embodiment.

[0049] In other words, the macro operation unit 150 is provided closer to the optical axis O than the end of the operation lever 132 that moves the extender lens group 130 in the H direction, the end being the farthest from the optical axis O. This makes it possible to prevent erroneous operations caused by unnecessary contact with the macro operation unit 150.

[0050] Furthermore, the lens device 100 according to this embodiment may be provided with an external connector 103 to which a cable 191 of a remote control means 190 can be connected, as shown in FIG. This allows the user to use the lens device 100 of this embodiment by remotely controlling the relay lens group 140 using a remote control means 190 via a cable 191 connected to the external connector 103, as shown in Figure 11. That is, as shown in FIG. 11, even if the user does not directly hold the imaging device 1, by holding and operating the remote control means 190, the user can operate the macro operation unit 150 provided in the lens device 100 according to this embodiment.

[0051] Furthermore, in the lens device 100 according to this embodiment, both the macro switch 151 and the volume knob 152a of the macro operation unit 150 are provided integrally with the extender housing 131, but this is not limiting. In other words, even if one is provided integrally with the extender housing 131 and the other is provided at a location separated from the extender housing 131, the above effect can be achieved by giving priority to commands from the macro switch 151 over commands from the volume knob 152a.

[0052] Furthermore, in the lens device 100 according to this embodiment, the macro operation unit 150 is provided with a macro switch 151 and a volume knob 152a, and commands from the macro switch 151 take priority over commands from the volume knob 152a. However, the present invention is not limited to this, and the lens device 100 according to this embodiment may be configured such that the macro switch 151 is not provided in the macro operation unit 150, and only the volume knob 152a is provided.

[0053] That is, the volume knob 152a alone may form a switch for inputting a command to the control unit 160 to move the macro operation unit 150, in other words, the relay lens group 140, to a predetermined position. In this case, for example, when the volume knob 152a is in the click position, the relay lens group 140 is in the OFF state, while by rotating the volume knob 152a from the click position, the relay lens group 140 can be transitioned to the ON state.

[0054] Furthermore, in the lens device 100 according to this embodiment, a relay lens group 140 is provided as a lens group that moves for macro photography, but other lens groups that move for macro photography may also be provided in addition to the relay lens group 140. That is, the macro lens group that is provided in the lens device 100 according to this embodiment and that moves for macro photography is not limited to the relay lens group 140.
