Description

[Technical Field]

[0001] The disclosure of this specification relates to an electric operating device, and more particularly to an electric operating device that electrically operates a lens device that inserts and retracts an optical system onto an optical axis, and a lens device that includes an electric operating device. [Background technology]

[0002] Conventional extender devices have been proposed with a structure in which a photographer operates an operating unit to insert or remove a lens group relative to the optical axis and change the focal length. Patent Document 1 discloses a structure in which a photographer operates a manual operating unit to rotate a lens support member that holds the lens group, and the lens support member abuts against a stopper provided at the end position, thereby holding the lens group on the optical axis. Patent Document 2 proposes a configuration in which an extender operating device is connected to a lens device, and a manual operating unit of the extender device is operated with the extender operating device to switch between inserting and retracting a variable magnification lens. Patent Document 3 discloses an extender operating device in which a remote operating member is attached to the extender unit, allowing the forward and backward movement of a variable magnification lens to be switched between manual and electric. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-352395 [Patent Document 2] Japanese Patent Application Publication No. 4-216518 [Patent Document 3] Japanese Patent Application Laid-Open No. 2006-292968 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the prior art disclosed in the aforementioned Patent Document 1, the focal length is changed by manually operating the manual operation unit of the extender device, but no structure for power operation is proposed. In contrast, Patent Documents 2 and 3 also propose structures for power operation. However, in Patent Document 2, when the extender operation device is connected to the extender device, the manual operation unit is covered by the extender operation device, so the manual switch lever cannot be operated with the extender operation device attached. Furthermore, in Patent Document 3, the manual operation member is exposed even in the power operation state, but in the power operation state, the remote operation member is connected to the motor, making manual operation impossible. Therefore, to perform manual operation, the remote operation member must be detached from the lens device and switched to the manual operation state.

[0005] Therefore, the electric operation device according to the embodiment provides an advantageous technique in that it allows both electric operation and manual operation of a lens device, for example. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention provides an electric operating device that electrically operates the operating unit of a lens device having an operating unit and a lens support member that supports a lens group and moves between an insertion position where the lens group is inserted onto the optical axis of the lens device and a retracted position where the lens group is retracted from the optical axis by rotating the operating unit, wherein at least a portion of the operating unit is exposed from the exterior of the electric operating device when the electric operating device is attached to the lens device, and the operating unit can be manually operated. [Effects of the Invention]

[0007] It is possible to provide a technology that is advantageous in that it allows both powered operation and manual operation of the lens device. [Brief explanation of the drawings]

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals, and redundant explanations will be omitted.

[0010] First Embodiment 1 is a diagram showing an example of the configuration of a lens device 1 according to a first embodiment. The lens device 1 includes a lens group (not shown) and an extender device 100.

[0011] 2 is a diagram showing an example of the configuration of the extender device 100 according to the first embodiment. The extender device 100 has an extender housing 101 (housing), a lens group 102, and a lens support member 103. The extender housing 101 supports the lens support member 103. The lens support member 103 supports the lens group 102 and rotates around an axis A to insert or remove the lens group 102 with respect to the optical axis O.

[0012] The biasing spring 104 (fixed spring) engages with the extender housing 101 and the lens support member 103, and the force of the biasing spring 104 biases the lens support member 103 to either an inserted state or a retracted state with respect to the optical axis O. In other words, the biasing spring 104 biases the support member 103 to be positioned at the inserted position or the retracted position.

[0013] The internal gear 105 is fixed integrally with the lens support member 103, and the center of the internal gear 105 is configured to be approximately coaxial with the axis A. The operation gear 106 meshes with the internal gear 105, and rotates integrally with the operation lever 107 (operation unit) around the axis B. That is, the internal gear 105 and the operation lever 107 rotate around the axis B.

[0014] As shown by the dashed line in FIG. 2, when the tip 107a of the operating lever 107 is in an upper position (first position), the lens group 102 is retracted from the optical axis O of the lens device 1. When the tip 107a of the operating lever 107 is in a lower position (second position) as shown by the solid line in FIG. 2, the lens group 102 is inserted into the optical axis O (insertion state). That is, by rotating the operating lever 107 around the axis B, the insertion and removal of the lens group 102 are switched. The position of the lens support member 103 in the retracted state is called the retracted position, and the position of the lens support member 103 in the inserted state is called the insertion position. The lens support member 103 moves between the insertion position and the retracted position by operating the operating lever 107.

[0015] FIG. 3 is a cross-sectional view of the operating lever 107. This figure is a cross-sectional view of the operating lever 107 taken along dashed line XX' in FIG. 2. The operating lever 107 is disposed outside the extender housing 101, and its end face in the optical axis O direction has at least two regions: a region 107b having a predetermined thickness, and a region 107c that is thinner than the region 107b. In other words, the thickness of the region 107b on the tip end 107a side of the operating lever 107 is thicker than the region 107c on the axis B side. Therefore, the surface of the region 107b on the side opposite the extender housing 101 is located farther from the surface of the extender housing 101 than the surface of the region 107c on the side opposite the extender housing 101.

[0016] 4 is a diagram showing a state in which an electric operating device 110 according to the first embodiment is attached to the lens device 1. The electric operating device 110 electrically operates the operating lever 107 of the lens device 1 to switch between an inserted state and a retracted state of the lens group 102. The electric operating device 110 can also be said to be an electric switching device that electrically switches between the inserted state and the retracted state. In this embodiment, an electric operating device 110 that is detachable from the lens device 1 will be described, but the electric operating device may also be formed integrally with the lens device 1.

[0017] With the electric operating device 110 attached, the tip 107a, which is the end of the operating lever 107 farther from the axis B, which is the center of rotation of the operating lever 107, is exposed to the outside of the exterior 110a of the electric operating device 110. Therefore, the user can manually operate the operating lever 107 even with the electric operating device 110 attached.

[0018] FIG. 5 is a diagram showing an example of the configuration of an electric operating device 110 according to the first embodiment. The electric operating device 110 has a motor 111. The motor 111 is a drive source that transmits driving force to gears, which will be described later. A worm 112 is fixed to the output shaft of the motor 111. The electric operating device 110 further has a worm wheel 113 that meshes with the worm 112, and a first gear 114 that rotates integrally with the worm wheel 113. A second gear 115, a third gear 116, and a fourth gear 117 mesh with the first gear 114 in this order. A switching pin 116a is integrally provided with the third gear 116, and a switching pin 117a is integrally provided with the fourth gear 117.

[0019] 6 is a side view of the switching pins 116a and 117a. This figure shows the switching pins 116a and 117a as viewed from the direction of dashed line YY' shown in FIG. 5 with the electric operating device 110 attached to the lens device 1. As shown in FIG. 6, the switching pins 116a and 117a are configured to have a length that overlaps with the region 107b of the operating lever 107 in the optical axis direction but does not overlap with the region 107c in the optical axis direction. In other words, the switching pins 116a and 117a have a length that allows them to abut with the region 107b of the operating lever 107 but not with the region 107c of the operating lever 107.

[0020] The switching (driving) state by the electric operating device 110 according to this embodiment will be described with reference to FIG. 7. FIG. 7 is a diagram illustrating electric operation by the electric operating device 110 according to the first embodiment. FIG. 7(A) shows a state in which the lens group 102 is retracted from the optical axis O. When a switching command is input to the electric operating device 110, the motor 111 operates, the third gear 116 rotates counterclockwise in the figure, and the fourth gear 117 meshing with the third gear 116 rotates clockwise. Continuing rotation results in the state shown in FIG. 7(B). The switching pin 116a of the third gear 116 abuts against the side surface of the region 107b of the operating lever 107. That is, the third gear 116 and the fourth gear 117 rotate while the switching pin 116a abuts against the operating lever 107, thereby driving (moving) the operating lever 107.

[0021] When the rotation continues and the switching pin 116a continues to press the operating lever 107 as shown in Figure 7(C), the operating lever 107 moves due to the force of the biasing spring 104 to the state shown in Figure 7(D), and the lens group 102 is inserted into the optical axis O. In other words, the lens support member 103 reaches the insertion position.

[0022] Thereafter, the motor 111 continues to drive and is stopped by a signal from a rotation detection means (not shown) when the state shown in Fig. 7(E) is reached (first stop state). At this time, the switching pin 116a is stopped within the range through which the area 107c of the operating lever 107 passes, in other words, at a position where the switching pin 116a does not come into contact with the operating lever 107. Therefore, even if the operating lever 107 is manually operated, the switching pin 116a and the operating lever 107 will not come into contact with each other. In other words, the operating lever 107 does not come into contact with the structure of the electric operating device 110, and therefore the operating lever 107 can be manually operated.

[0023] When a switching command is input again to the electric operating device 110, the motor 111 starts operating. At this time, the motor 111 rotates in the same direction as before. That is, the third gear 116 and the fourth gear 117 rotate in the same direction when moving the lens support member 103 from the insertion position to the retracted position and when moving it from the retracted position to the insertion position. When the state shown in FIG. 7(F) is reached, the switching pin 117a of the fourth gear 117 abuts against the side surface of the region 107b of the operating lever 107. That is, the third gear 116 and the fourth gear 117 rotate while the switching pin 117a abuts against the operating lever 107, thereby driving (moving) the operating lever 107.

[0024] When the rotation continues and the switching pin 117a continues to press the operating lever 107 as shown in Figure 7(G), the operating lever 107 moves due to the force of the biasing spring 104 to the state shown in Figure 7(H), and the lens group 102 retracts from the optical axis O. In other words, the lens support member 103 reaches the retracted position.

[0025] After that, the motor 111 continues to drive and returns to the state shown in FIG. 7(A). When the state shown in FIG. 7(A) is reached, the motor is stopped by a signal from a rotation detection means (not shown) (second stopped state). At this time, the switching pin 117a is stopped within the range through which the area 107c of the operating lever 107 passes, in other words, at a position where the switching pin 117a does not come into contact with the operating lever 107. Therefore, even in this case, even if the operating lever 107 is manually operated, the switching pin 117a and the operating lever 107 will not come into contact with each other, i.e., the operating lever 107 will not come into contact with the structure of the electric operating device 110. This makes it possible to manually operate the operating lever 107.

[0026] As described above, in the lens device 1 of this embodiment, even after the electric operating device 110 is attached, the tip 107a of the operating lever 107 is exposed from the exterior of the electric operating device 110, so the user can manually operate the operating lever.

[0027] Driving in a stopped state according to the first embodiment will be described with reference to FIG. 8. FIG. 8 is a diagram illustrating driving in a stopped state according to the first embodiment. FIG. 8(A) is a diagram illustrating a case where the operating lever 107 is manually operated downward from the state in FIG. 7(A) where the motor 111 is stopped (second stopped state). When the operating lever 107 is manually operated downward in the drawing from the state in FIG. 7(A) where the motor 111 is stopped (second stopped state), the state shown in FIG. 8(A) is reached. Along the way, region 107c of the operating lever 107 passes through the switching pin 117a, but region 107c is thinner than region 107b and does not come into contact with the switching pin 117a, so the operating lever 107 does not come into contact with the switching pin 117a.

[0028] Fig. 8(B) is a diagram illustrating a case where operation lever 107 is manually operated upward from the state in Fig. 7(E) where motor 111 is stopped (first stop state). When operation lever 107 is manually operated upward in the figure from the state in Fig. 7(E) where motor 111 is stopped (first stop state), the state becomes as shown in Fig. 8(B). In this case as well, region 107c of operation lever 107 passes over switching pin 116a midway, but region 107c is thinner than region 107b and does not come into contact with switching pin 116a, so operation lever 107 does not come into contact with switching pin 116a.

[0029] Furthermore, in this embodiment, the electric operating device 110 drives the motor 111 in the same direction regardless of the operating direction of the operating lever 107. Therefore, even if manual operation is performed after electric operation, it is possible to perform a switching operation (electric operation by the electric operating device 110) without changing the operating direction of the motor 111.

[0030] Furthermore, in this embodiment, the third gear 116, which is equipped with a switching pin 116a that abuts against the operating lever 107 when the lens group 102 is driven in a direction to lift it (a direction against gravity) (here, when moving it from the retracted position to the inserted position), has fewer meshing stages from the motor 111 than the fourth gear 117. That is, in this embodiment, the driving force of the motor 111 is transmitted to the third gear 116, and then from the third gear 116 to the fourth gear 117. By arranging the gear that requires more force in a position that provides a more efficient reduction mechanism, it is possible to reduce the power consumption of the motor 111.

[0031] In the above-described embodiment, the lens support member 103 is configured to rotate about an axis A in a direction along the optical axis O, thereby inserting and removing the lens group 102 relative to the optical axis O. However, the present invention is not limited to this configuration, and any configuration may be used as long as the lens group 102 can be inserted and removed relative to the optical axis O using the rotational power of the operation lever 107. For example, the lens group 102 may be inserted and removed relative to the optical axis O by rotating around an axis in another direction, or by converting the rotational power of the operation lever 107 to slide the lens group 102. In addition, if the lens support member 103 is configured to rotate about an axis in a direction along the optical axis O, the configuration can be simplified and the overall size of the device can be reduced.

[0032] In this embodiment, the operating lever 107 has a stepped shape with different thicknesses between the region 107b and the region 107c, but the shape is not limited to a stepped shape as long as it has a region that contacts the switching pin 116a and the switching pin 117a and a region that does not contact them. For example, the operating lever 107 may have a sloped shape in which the thickness decreases from the tip end 107a side toward the axis B side.

[0033] Second Embodiment 9 is a diagram showing an example of the configuration of a lens device 2 according to the second embodiment. The lens device 1 includes a lens group (not shown) and an extender device 200.

[0034] 10 is a diagram showing an example of the configuration of an extender device 200 according to the second embodiment. The extender device 200 has an extender housing 201, a lens group 202, and a lens support member 203. The extender housing 201 supports the lens support member 203. The lens support member 203 supports the lens group 202 and rotates around an axis C to insert or remove the lens group 202 with respect to the optical axis O.

[0035] The biasing spring 204 engages with the extender housing 201 and the lens support member 203, and the force of the biasing spring 204 biases the lens support member 203 to either an inserted state or a retracted state relative to the optical axis O. In other words, the biasing spring 204 biases the support member 203 to be positioned at either the inserted position or the retracted position. The operating lever 205 rotates integrally with the lens support member 203 around the axis C. In this figure, the retracted state is indicated by a dashed line, and the inserted state is indicated by a solid line.

[0036] 11 is a diagram showing a state in which an electric operating device 210 according to the second embodiment is attached to the lens device 2. When the electric operating device 210 is attached, the operating lever end surface 205a is exposed to the outside of the exterior casing 210a of the electric operating device 210, even when the electric operating device 210 is attached. Therefore, the user can operate the operating lever 205 even when the electric operating device 210 is attached.

[0037] 12 is a diagram showing an example of the configuration of an electric operating device 210 according to the second embodiment. The electric operating device 210 has a motor 211. A worm 212 is fixed to the output shaft of the motor 211. The electric operating device 210 further has a worm wheel 213 that meshes with the worm 212, and a first gear 214 that rotates integrally with the worm wheel 213. A second gear 215 and a third gear 216 mesh with the first gear 214 in this order. A switching pin 215a is integrally provided with the second gear 215, and a switching pin 216a is integrally provided with the third gear 216.

[0038] The switching (driving) state by the electric operating device 210 according to this embodiment will be described with reference to Fig. 13. Fig. 13 is a diagram for explaining electric operation by the electric operating device 210 according to the second embodiment. This diagram simply shows the relationship between the operating lever 205 and the electric operating device 210 as viewed from the optical axis O side shown in Fig. 12.

[0039] FIG. 13(A) shows a state in which the lens group 202 is retracted from the optical axis O. When a switching command is input to the electric operating device 210 and the motor 211 operates, the second gear 215 rotates counterclockwise and the third gear 216 meshing with the second gear 215 rotates clockwise. Continuing rotation results in the state shown in FIG. 13(B). The switching pin 215a of the second gear 215 abuts against the side surface of the operating lever 205. That is, the second gear 215 and the third gear 216 rotate while the switching pin 215a abuts against the operating lever 205, and the operating lever 205 is driven (moved).

[0040] When rotation is further continued and switching pin 215a continues to press operating lever 205 as shown in Fig. 13(C), operating lever 205 moves due to the force of biasing spring 204, and lens group 202 is inserted onto optical axis O, resulting in the state shown in Fig. 13(D). That is, when lens support member 203 reaches the insertion position, lens group 202 is inserted onto the optical axis.

[0041] Thereafter, the motor 211 continues to drive, and when it reaches the state shown in Figure 13(E), it is stopped by a signal from a rotation detection means (not shown) (first stop state). At this time, the switching pin 215a is outside the range through which the operating lever 205 passes, in other words, the switching pin 215a is stopped at a position where it does not come into contact with the operating lever 205. Therefore, even if the operating lever 205 is manually operated, the switching pin 215a and the operating lever 205 will not come into contact with each other, and the operating lever 205 can be manually operated.

[0042] When a switching command is input again to the electric operating device 210, the motor 211 starts operating. At this time, the motor 211 is rotating in the same direction as before. That is, the second gear 215 and the third gear 216 rotate in the same direction when moving the lens support member 203 from the insertion position to the retracted position and when moving it from the retracted position to the insertion position. When the state shown in FIG. 13(F) is reached, the switching pin 216a of the third gear 216 abuts against the side surface of the operating lever 205. That is, the second gear 215 and the third gear 216 rotate while the switching pin 216a abuts against the operating lever 205, thereby driving (moving) the operating lever 205.

[0043] When rotation is further continued and the switching pin 216a continues to press the operating lever 205 as shown in Figure 13(G), the operating lever 205 moves due to the force of the biasing spring 204, and assumes the state shown in Figure 13(H), with the lens group 202 retracting from the optical axis O. In other words, the lens support member 203 reaches the retracted position.

[0044] After that, the motor 211 continues to drive and returns to the state shown in Fig. 13(A). When the state shown in Fig. 13(A) is reached, the motor is stopped by a signal from a rotation detection means (not shown) (second stopped state). At this time, the switching pin 216a is outside the range through which the operating lever 205 passes; in other words, the switching pin 216a is stopped at a position where it does not come into contact with the operating lever 205. Therefore, even in this case, even if the operating lever 205 is manually operated, the switching pin 216a and the operating lever 205 will not come into contact with each other, and the operating lever 205 can be manually operated. As described above, in the lens device of this embodiment, the end face of the operating lever is exposed from the exterior of the electric operating device even after the electric operating device is attached, making it possible to manually operate the operating lever.

[0045] Driving in a stopped state according to the second embodiment will be described with reference to FIG. 14. FIG. 14 is a diagram illustrating driving in a stopped state according to the second embodiment. FIG. 14(A) is a diagram illustrating a case where the operating lever 205 is manually operated downward from the state in which the motor 211 is stopped (second stopped state) in FIG. 13(A). When the operating lever 205 is manually operated downward in the drawing from the state in which the motor 211 is stopped (second stopped state) in FIG. 7(A), the state shown in FIG. 8(A) is achieved. During the switching, that is, while the operating lever 205 is being manually operated, the operating lever 205 does not come into contact with the switching pin 216a.

[0046] Figure 14(B) is a diagram illustrating a case where operation lever 205 is manually operated upward from the state in which motor 211 is stopped (first stop state) in Figure 13(E). When operation lever 205 is manually operated upward in the figure from the state in which motor 211 is stopped (first stop state) in Figure 13(E), the state becomes as shown in Figure 14(B). In this case as well, operation lever 205 and switching pin 215a do not come into contact with each other.

[0047] Furthermore, since the electric operating device 210 drives the motor 211 in the same direction regardless of the operating direction of the operating lever 205, even if manual operation is performed after electric operation, switching operation can be performed without changing the operating direction of the motor 211.

[0048] Furthermore, in this embodiment, the second gear 215, which is equipped with a switching pin 215a that abuts against the operation lever 205 when the lens group 202 is driven in a direction to lift (a direction against gravity) (here, when moving from the retracted position to the inserted position), is configured to have fewer meshing stages from the motor 211 than the third gear 216. That is, in this embodiment, the driving force of the motor 211 is transmitted to the second gear 215, and then from the second gear 215 to the third gear 216. By arranging the gear that requires more force in a position that provides a more efficient reduction mechanism, it is possible to reduce the power consumption of the motor 211.

[0049] Fig. 15 is a diagram showing another example of the configuration of the electric operating device 210 according to the second embodiment. In this embodiment, as an example, a configuration has been described in which the rotation axes of the second gear 215 and the third gear 216 are arranged approximately parallel to each other. However, as shown in Fig. 15, the rotation axis of the second gear 215 and the rotation axis of the third gear 216 may be arranged so that one is oblique to the other in accordance with the operating range of the operating lever 205. The gear shape is not limited to spur gears, and may be bevel gears.

[0050] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes are possible within the scope of the gist of the present invention.
