  Although a digital camera having a plurality of imaging optical systems instead of a single imaging optical system is assumed, it is possible to cover a wide imaging range without changing lenses by changing the focal length of each. However, there is a problem that the internal configuration becomes complicated as compared with a single imaging optical system. For example, assuming a digital camera including a first imaging optical system and a second imaging optical system, a motor that drives a zoom lens of the first imaging optical system, a motor that drives a focus lens, and a zoom lens of the second imaging optical system A total of four drive motors, i.e., a motor for driving the lens and a motor for driving the focus lens, are required, resulting in an increase in size and cost of the digital camera. As disclosed in the above prior art, the zoom lens and focus lens of the first imaging optical system are driven by a single drive motor, and the zoom lens and focus lens of the second imaging optical system are separated from each other by a single drive motor. However, it is desirable that the first imaging optical system and the second imaging optical system are driven in conjunction with each other, and the zoom lens of the first imaging optical system and the zoom lens of the second imaging optical system are desirable. Is preferably driven by a single drive motor, or the focus lens of the first imaging optical system and the focus lens of the second imaging optical system can be driven by a single drive motor.

  Furthermore, even when the zoom lenses of the first imaging optical system and the second imaging optical system move in conjunction with each other, some users may want to change the interlocking method.

  It is an object of the present invention to share a zoom lens drive motor of each imaging optical system in an imaging apparatus having a plurality of optical systems, simplify the configuration for arbitrarily changing the zoom lens interlocking method, and improve usability. It is to improve.

  The present invention is an imaging apparatus having a plurality of optical systems including a first imaging optical system and a second imaging optical system having a different angle of view from the first imaging optical system, wherein the first imaging optical system A first lens for zooming, the second imaging optical system has a second lens for zooming, and the first lens and the second lens are driven together by a common zooming drive motor, When the first lens moves from the wide-angle side to the narrow-angle side between the zooming drive motor and the first lens and the second lens, the second lens moves from the wide-angle side to the narrow-angle side. A switching mechanism that selectively switches between a first movement mode and a second movement mode in which the second lens moves from the narrow-angle side to the wide-angle side when the first lens moves from the wide-angle side to the narrow-angle side; It is characterized by that.

  In one embodiment of the present invention, the switching mechanism is selected as a sun gear coupled to the zooming drive motor, first and second planetary gears meshed with the sun gear, and the first planetary gear. An idle gear that meshes with the second planetary gear, and a drive gear that meshes with the idle gear and that engages with the idle gear, and the sun gear rotates to drive the first lens, and the drive gear The second lens is driven by the rotation of the first gear, and when the first planetary gear meshes with the idle gear, the drive gear rotates together with the sun gear via the idle gear, and the second planetary gear is driven. When meshing with a gear, it rotates with the sun gear without going through the idle gear.

  According to the present invention, it is possible to reduce the number of drive motors and to arbitrarily switch the interlocking method of the zoom lens for the first imaging optical system and the second imaging optical system.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The digital camera according to the present embodiment has two imaging optical systems, a first imaging optical system (wide-side optical system) having a relatively wide angle of view and a second imaging optical system (tele-side optical system) having a relatively narrow angle of view. The system is provided.

  FIG. 1 shows the internal configuration of the digital camera of this embodiment. The first imaging optical system has a zoom lens with a focal length range of 39 mm to 117 mm in terms of 35 mm film. The user operates the zoom button to set the zoom position. When the desired zoom position is reached, the shutter button is operated to take a picture. The flash is appropriately controlled according to the brightness of the subject, and the captured image is displayed on the LCD. The zoom lens is a so-called bending optical system, and the subject light incident from the first lens group 100 is bent at a right angle by the prism 101, and the first image sensor 110 via the zoom lens groups 102 and 104 and the focus lens group 108. An image of the subject is formed on the screen. The zoom lens groups 102 and 104 and the focus lens group 108 are each guided by a rod 112 and configured to be movable in the optical axis direction. The combined focal length of the entire lens is changed by moving these lens groups. The first imaging optical system includes two zoom lens groups 102 and 104, and the zoom lens group 102 is disposed on the front side (subject side) of the shutter / diaphragm assembly 600, and the zoom lens group 104 is located behind the shutter / diaphragm assembly 600. On the side (image sensor side). The zoom lens group 104 is driven by a drive motor 500 different from the zoom lens group 102.

  The second imaging optical system has a zoom lens having a focal length range of 130 mm to 390 mm in terms of 35 mm film. This zoom lens is also a bending optical system, and subject light incident from the first lens group 200 is bent at a right angle by the prism 201, and an object image is applied to the second image sensor 210 via the zoom lens group 202 and the focus lens group 206. Is imaged.

  The zoom lens 202 and the focus lens 206 are each guided by a rod 212 and configured to be movable in the optical axis direction. The combined focal length of the entire lens is changed by moving these lens groups.

  In the present embodiment, zooming drive motors 300 and 500 and a focusing drive motor 400 are provided as drive motors for these lens groups. The drive motors shared by the first image pickup optical system and the second image pickup optical system are the drive motors 300 and 400. Hereinafter, a drive mechanism by these drive motors 300 and 400 will be described.

  A gear is connected to the focusing motor 400, and the other two gears mesh with this gear. One gear meshes with an outer peripheral gear 106a formed on the outer periphery of the hollow cylindrical lens guide ring 106, and rotates the lens guide ring 106. A screw is formed on the inner periphery of the lens guide ring 106, and the focus lens group 108 is held in mesh with the screw. When the lens guide ring 106 rotates, the focus lens group 108 meshing with the inner peripheral screw is guided by the rod 112 and moves in the optical axis direction. The other gear is connected to the feed screw 230, and a nut is screwed to the feed screw 230, and the focus lens group 206 is connected to this nut. When the feed screw 230 rotates, the focus lens group 206 is guided by the rod 212 and moves in the optical axis direction. Therefore, the focus lens group 108 of the first imaging system and the focus lens group 206 of the second imaging optical system both move in the optical axis direction by the rotation of the single focusing motor 400. The focusing drive motor 400 rotates in the forward and reverse directions in response to a command from a control circuit of a digital camera (not shown) so as to perform an autofocus operation so that the in-focus subject distances of both imaging optical systems are the same. Set to That is, when the first imaging optical system is in focus at infinity, the second imaging optical system is also focused at infinity, and the first imaging optical system is focused at a subject distance of 2 m. The second imaging optical system is also set so as to focus on a subject distance of 2 m.

  The second imaging optical system is a tele-side optical system having a relatively narrow angle of view, and the amount of movement of the focus lens group 206 is relatively large. For this reason, in this embodiment, the focus lens group 206 is directly driven by the feed screw 230. On the other hand, the first imaging optical system is a wide-side optical system with a relatively wide angle of view, and the amount of movement of the focus lens group 108 is relatively small and the resolution needs to be increased. For this reason, the focus lens group 108 achieves a desired reduction ratio by a combination of a gear and the outer peripheral gear 106a of the lens guide ring 106, not a feed screw. That is, the resolution of the focus lens group 108 is improved by a combination of a gear having a small number of teeth and an outer peripheral gear 106a of the lens guide ring 106 having a large number of teeth. Since the focus lens group 108 meshes with the inner peripheral screw of the lens guide ring 106, the resolution can also be adjusted by adjusting the pitch of the inner peripheral screw. The resolution of the focus lens group 108 can be roughly adjusted by the reduction ratio of the gear and the outer peripheral gear 106a, and the resolution of the focus lens group 108 can be finely adjusted by the inner peripheral screw pitch of the lens guide ring 106.

  On the other hand, a switching mechanism 350 is connected to the zooming drive motor 300. The switching mechanism 350 is a zooming drive motor that includes a feed screw 120 into which a nut of the zoom lens group 102 of the first imaging optical system is screwed and a feed screw 220 into which a nut of the zoom lens group 202 of the second imaging optical system is screwed. The rotation direction of the feed screw 120 and the feed screw 220 is selectively switched while being connected to the drive 300. By switching the rotation direction of the feed screw 120 and the feed screw 220, the movement direction along the optical axis of the zoom lens group 102 and the movement direction along the optical axis of the zoom lens group 202 are switched. In other words, when the rotation directions of the feed screw 120 and the feed screw 220 are the same, both the zoom lens group 102 and the zoom lens group 202 move in the same direction along the optical axis, and the rotation direction of the feed screw 120 and the feed screw 220. Are reversely rotated, the zoom lens group 102 and the zoom lens group 202 move in opposite directions along the optical axis. Specifically, when the feed screw 120 and the feed screw 220 rotate in the same direction, when the zoom lens group 102 moves from the wide-angle end (wide end) to the narrow-angle end (tele end), the zoom lens group 202 is the same. When the zoom lens group 102 moves from the tele end to the wide end, the zoom lens group 202 similarly moves from the tele end to the wide end. When the feed screw 120 and the feed screw 220 rotate in opposite directions, when the zoom lens group 102 moves from the wide end toward the tele end, the zoom lens group 202 moves from the tele end toward the wide end, and the zoom lens group When the lens 102 moves from the tele end toward the wide end, the zoom lens group 202 moves from the wide end toward the tele end. The switching mechanism 350 is manually switched by the user.

  FIG. 2 shows the configuration of the switching mechanism 350. It is the block diagram which looked at the internal structure in FIG. 1 from the prisms 101 and 201 side. The switching mechanism 350 includes a switching lever 352, a sun gear G1, planetary gears G2 and G3, an idle gear G4, and a feed screw 120 driving gear G5. The sun gear G1 and the two planetary gears G2 and G3 mesh with each other, and these gears G1 to G3 are all fixed to the switching lever 352. The sun gear G1 is directly connected to the zooming drive motor 300, and the feed screw 220 is driven by the sun gear G1. That is, the sun gear G1 drives the planetary gears G2 and G3 and functions as a feed screw 220 driving gear. The idle gear G4 and the feed screw 120 driving gear G5 are engaged with each other, the idle gear G4 is disposed in the vicinity of the planetary gear G2 so as to be able to mesh with the planetary gear G2, and the feed screw 120 driving gear G5 can be engaged with the planetary gear G3. It arrange | positions in the planetary gear G3 vicinity. The switching lever 352 is pivotally supported in the direction of the arrow 354 in the figure, and when the switching lever 352 is at an intermediate position (neutral position) between the A position and the B position, the planetary gear G2 is an idle gear as shown in the figure. The planetary gear G3 does not mesh with the feed screw 120 driving gear G5 without meshing with G4. In this case, since the feed screw 220 is driven by the sun gear G1 and the feed screw 120 is not driven, only the zoom lens group 202 moves in the optical axis direction.

  3 and 4 show a configuration when the switching lever 352 is switched to the A position. As shown in FIG. 4, the planetary gear G2 meshes with the idle gear G4, and the idle gear G4 also rotates through the planetary gear G2 by the rotation of the sun gear G1. Since the idle gear G4 meshes with the feed screw 120 driving gear G5, the feed screw 120 driving gear G5 also rotates. The rotation direction of the sun gear G1 and the rotation direction of the feed screw 120 driving gear G5 are opposite to each other. Accordingly, the rotation direction of the feed screw 220 driven by the sun gear G1 and the feed screw 120 driven by the feed screw 120 driving gear G5 rotate in opposite directions, and the zoom lens group 102 is moved from the wide end to the tele end. When moving toward, the zoom lens group 202 moves from the tele end toward the wide end. FIG. 3 shows a case where the zoom lens group 102 is located at the tele end and the zoom lens group 202 is located at the wide end.

  5 and 6 show a configuration when the switching lever 352 is switched to the B position. As shown in FIG. 6, the planetary gear G3 meshes with the feed screw 120 driving gear G5, and the rotation of the sun gear G1 also rotates the feed screw 120 driving gear G5 via the planetary gear G3. The rotation direction of the sun gear G1 and the rotation direction of the feed screw 120 driving gear G5 are the same. Therefore, the rotation direction of the feed screw 220 driven by the sun gear G1 and the feed screw 120 driven by the feed screw 120 driving gear G5 rotate in the same direction, and the zoom lens group 102 is changed from the wide end to the tele end. In the case of moving toward the zoom lens group 202, the zoom lens group 202 also moves from the wide end toward the tele end. FIG. 5 shows a case where the zoom lens group 102 is located at the tele end and the zoom lens group 202 is also located at the tele end.

  In this way, by switching the switching lever 352 of the switching mechanism 350 to either the A position or the B position, the interlocking method of the zoom lens group 102 of the first imaging optical system and the zoom lens group 202 of the second imaging optical system is changed. It can be switched easily. The user can switch to one of the interlocking methods according to the subject and the shooting situation, and perform zooming and shooting. For example, when switching from the first imaging optical system to the second imaging optical system, the zoom lens group 202 is preferably positioned at the wide end when the zoom lens group 102 reaches the tele end. In this case, the switching lever 352 is used. Is set to the A position, and the moving directions of the zoom lens group 102 and the zoom lens group 202 are preferably opposite to each other. On the other hand, when the first imaging optical system and the second imaging optical system are both in the operating state and the two optical systems are simultaneously photographed, the zooming direction is preferably the same. In this case, the switching lever 352 is set to B. It is preferable that the moving direction of the zoom lens group 102 and the zoom lens group 202 is set to the same direction by setting the position.

  Hereinafter, the user operation in the present embodiment will be described in more detail. When the power of the digital camera is turned on, the digital camera is set to the initial state by the control circuit. In this initial state, the first imaging optical system is in an operating state, the zoom position of the first imaging optical system is set to the wide end (39 mm), and the zoom position of the second imaging optical system is set to the tele end (390 mm). Is done.

  When the user sets the switching lever 352 of the switching mechanism 350 to the A position and operates the tele side of the zoom button from the initial state, the zooming drive motor 300 rotates to increase the focal length of the first imaging optical system. While moving (zoom up), it is moved in a direction to reduce the focal length of the second imaging optical system (zoom down).

  Since the first imaging optical system is operating in the initial setting, the image displayed on the LCD is an image obtained by the first imaging optical system, which changes from the wide end (39 mm) to a zoomed-up image. Go. If the tele side of the zoom button is continuously operated, the tele end (117 mm) of the first imaging optical system is reached, but if the operation is continued further, an image obtained by applying electronic zoom to the image of the first imaging optical system is displayed. . Then, when the setting reaches the wide end (130 mm) of the second imaging optical system, the imaging optical system is automatically switched, and the second imaging optical system enters an operating state and the image is displayed on the LCD. At this time, since the first imaging optical system and the second imaging optical system are zoomed so that the directions in which the focal lengths change are opposite to each other as described above, the first imaging optical system reaches the tele end when the first imaging optical system reaches the tele end. The two imaging optical systems have reached the wide end, and can be switched smoothly without moving the zoom lens group 202 of the second imaging optical system again at the time of switching. If the zoom button is further operated to the tele side, the zooming drive motor 300 will reversely move and move in the direction to increase the focal length of the second imaging optical system (zoom up).

  When the zoom button is operated to the wide side, the operation is the reverse of the above zoom-up operation. That is, the zooming drive motor 300 rotates and moves in a direction to increase the focal length of the first imaging optical system (zoom up), and moves in a direction to decrease the focal length of the second imaging optical system (zoom down). ). If you continue to operate the wide side of the zoom button, you will reach the wide end of the second imaging optical system. However, if you continue to operate the zoom button, the imaging optical system will automatically switch, and the first imaging optical system will be in the operating state. An image is displayed on the LCD. Since the first imaging optical system and the second imaging optical system perform zooming so that the directions in which the focal lengths change are opposite to each other, the first imaging optical system is at the tele end when the second imaging optical system reaches the wide end. Thus, the switching can be performed smoothly without moving the zoom lens group 102 of the first imaging optical system again at the time of switching.

  The user can switch the switching lever 352 of the switching mechanism 350 from the A position to the neutral position and further to the B position when the first imaging optical system reaches the tele end and the second imaging optical system reaches the wide end. . When the switching lever 352 is set to the neutral position, only the zoom lens group 202 of the second imaging optical system moves. When the first imaging optical system reaches the tele end, the second imaging optical system is positioned at the wide end, but when the switching lever 352 is set to the neutral position, the first imaging optical system maintains the tele end position, Only the second imaging optical system moves from the wide end toward the tele end and reaches the tele end. Thereby, both the first imaging optical system and the second imaging optical system reach the tele end. In this state, when the switching lever 352 is set to the B position and the zoom button is operated to the wide side, the zooming drive motor 300 rotates, the first imaging optical system moves from the tele end to the wide end, 2 The imaging optical system also moves from the tele end toward the wide end. If the user operates the zoom button to the tele side without operating the switching lever 352 (that is, with the B position set) after both the first imaging optical system and the second imaging optical system reach the wide end, the first Both the imaging optical system and the second imaging optical system move from the wide end to the tele end, and eventually reach the tele end. When the user sets the switching lever 352 from the B position to the neutral position when both the first imaging optical system and the second imaging optical system have reached the wide end, only the second imaging optical system is directed from the wide end to the tele end. Move and reach the tele end. As a result, the first imaging optical system is positioned at the wide end and the second imaging optical system is positioned at the tele end. Thereafter, when the user sets the switching lever 352 to the A position and operates the zoom button to the tele side, One imaging optical system moves from the wide end toward the tele end, and the second imaging optical system moves from the tele end toward the wide end.

  7 and 8 are rear views of the digital camera. An LCD is provided on the back of the digital camera, and a screen obtained by the imaging optical system in operation is displayed. The zoom button 10 has operation buttons on the wide side (W) and tele side (T), and operates the tele side when zooming up, and operates the wide side when zooming down. The zoom button 10 also serves as an operation changeover switch for switching the imaging optical system in operation. That is, both the wide-side operation button and the tele-side operation button of the zoom button 10 are configured to be clickable, and an operation switching is instructed to the control circuit by double-clicking. Switching the operation to the first imaging optical system corresponds to double-clicking the wide-side operation button, and switching to the second imaging optical system corresponds to double-clicking the tele-side operation button. When the user double-clicks the tele-side operation button of the zoom button 10 while the first image pickup optical system is operating, the operation optical system is switched from the first image pickup optical system to the second image pickup optical system, and obtained by the second image pickup optical system. An image is displayed on the LCD. Further, when the user double-clicks the wide side operation button of the zoom button 10 while the second imaging optical system is operating, the operating optical system is switched from the second imaging optical system to the first imaging optical system. The displayed image is displayed on the LCD.

  The movement mode changeover switch 12 is linked to the changeover lever 352 and changes over the changeover lever 352 to the A position, the neutral position, and the B position. The movement mode changeover switch 12 is constituted by a slide switch, for example, and is set to the A position, the neutral position, and the B position by sliding in the direction of the arrow in the figure.

  In the present embodiment, the movement method can be switched together with the switching between the first imaging optical system and the second imaging optical system as described above. Therefore, it is preferable that the current movement mode is clearly indicated to the user. FIG. 7 shows a screen display example when the switching lever 352 is set to the B position and both the first imaging optical system and the second imaging optical system move in the same direction along the optical axis. A display 100A shows zooming of the first imaging optical system, and a display 200A shows zooming of the second imaging optical system. The lower end is the wide end, and the upper end is the tele end. The position of the zoom lens group 102 of the first imaging optical system and the position of the zoom lens group 202 of the second imaging optical system are shown, and the optical system in the operating state is shown thick. In the figure, both the first imaging optical system and the second imaging optical system are located at the wide end, and the second imaging optical system is in an operating state. FIG. 8 shows a screen display example when the switching lever 352 is set to the A position and the first imaging optical system and the second imaging optical system move in opposite directions along the optical axis. The first imaging optical system is located at the wide end, the second imaging optical system is located at the tele end, and the first imaging optical system is in an operating state. By making such a display, which of the first imaging optical system and the second imaging optical system is in operation, and which movement mode the first imaging optical system and the second imaging optical system are in, Furthermore, the zoom positions of the first imaging optical system and the second imaging optical system can be easily identified.

  7 and 8, when the first image pickup optical system and the second image pickup optical system are not operated selectively but the first image pickup optical system and the second image pickup optical system are operated together, the LCD has the first image pickup optical system. An image obtained by the imaging optical system and an image obtained by the second imaging optical system are displayed in a superimposed manner or in parallel. In this case, both the displays 100A and 200A display that the zoom position is in bold line and that both are operating.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this, A various change is possible.

  For example, in this embodiment, the feed screw 220 is connected to the sun gear G1, and the feed screw 120 is connected to the gear G5. However, the feed screw 120 is connected to the sun gear G1 to move the zoom lens group 102, The zoom lens group 202 may be moved by connecting a feed screw 220 to the gear G5. In this case, when the switching lever 352 is set to the neutral position, the zoom lens group 202 maintains the current position, while the zoom lens group 102 is driven alone by the zooming motor 300.
