  In a conventional imaging apparatus, the light emitting unit is always in a protruding state when the lens barrel that is ready for imaging is extended, and is always in the retracted state when the lens barrel that is incapable of imaging is retracted.

  This is advantageous in that the opportunity of photographing is not missed by setting the light emitting unit in a protruding state at the same time as the power is turned on. However, since the light emitting unit protrudes as soon as the power is turned on, the subject is expected to emit the strobe light.

  In addition, if the movement between the usage state and the storage state of the light emitting unit is interlocked with the movement between the retracted position and the extended position of the lens barrel, the light emitting unit always protrudes in the imaging enabled state, and the holding of the imaging device There was a problem of disturbing.

  The object of the present invention is to move the light emitting unit between the use state and the storage state in conjunction with the lens barrel, and to store the light emission unit in the use state by manual operation without interlocking with the lens barrel. The state to be moved can be switched between the states.

  To achieve the above object, the present invention provides a light emitting unit movable between a use state and a storage state, a drive member driven by a drive source, and the light emission by moving in conjunction with the drive member. A moving member that engages with the unit to move the light emitting unit from the housed state to the use state; an engaged state in which the moving member and the light emitting unit engage; the moving member and the light emitting unit; A switching member that switches between a disengaged state in which the engagement of the light emitting unit is released, and an operating part that can be operated by a user is formed on the switching member, wherein the light emitting unit is in the retracted state. In this case, the user can operate.

  Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS.

  FIG. 1 is a diagram for explaining a digital camera as an image pickup apparatus embodying the present invention and for explaining six states of the digital camera of this embodiment. As shown in FIG. 1, the digital camera of this embodiment includes a power button 4 and a light emitting unit interlocking switching lever 3.

  The power button 4 switches the digital camera from the imaging disabled state to the imaging enabled state and switches the digital camera from the imaging enabled state to the imaging disabled state.

  When the digital camera is switched from the imaging disabled state to the imaging enabled state, the lens barrel unit L moves from the retracted state to the extended state. When the digital camera switches from the imageable state to the imageable state, the lens barrel unit L moves from the extended state to the retracted state.

  The light emitting unit interlocking switching lever 3 switches whether to perform the up / down operation of the light emitting unit 1 in conjunction with the operation of the lens barrel unit L.

  When the light emitting unit interlocking switching lever 3 is switched to interlocking on, the light emitting unit 1 moves from the retracted state to the used state in conjunction with the operation of moving the lens barrel unit L from the retracted state to the extended state. Then, in conjunction with the movement of the lens barrel unit L from the extended state to the retracted state, the light emitting unit 1 moves from the use state to the housed state.

  When the light emitting unit interlocking switching lever 3 is switched to interlocking off, the light emitting unit 1 does not interlock with the operation of the lens barrel unit L. That is, if the light emitting unit 1 is in the retracted state, the light emitting unit 1 remains in the retracted state even if the lens barrel unit L moves from the retracted state to the extended state or from the extended state to the retracted state. . Similarly, if the light emitting unit 1 is in use, the light emitting unit 1 remains in use even if the lens barrel unit L moves from the retracted state to the extended state or from the extended state to the retracted state. Become.

  The operation when the light emitting unit interlocking switching lever 3 is switched to interlocking on will be described with reference to FIGS.

  By moving the light emitting unit interlocking switching lever 3 in the direction of arrow G in FIG. 1A, the light emitting unit interlocking switching lever 3 is switched to interlocking on. On the other hand, the light emitting unit interlocking switching lever 3 is switched to interlocking off by moving the light emitting unit interlocking switching lever 3 in the direction of arrow H in FIG.

  FIG. 1A shows a power-off state or a hibernation state, which is an example of an imaging impossible state. In this state, the lens barrel unit L is in the retracted state, and the light emitting unit 1 is in the housed state.

  FIG. 1B shows an example of an imageable state, and shows a state where the power is turned on from the state shown in FIG. 1A by operating the power button 4. When the power button 4 is operated, the digital camera is switched from the imaging disabled state to the imaging enabled state, and the lens barrel unit L moves from the retracted state to the extended state. Since the light emitting unit interlocking switching lever 3 is interlocked on, the light emitting unit 1 moves from the retracted state to the used state in conjunction with the operation of the lens barrel unit L moving from the retracted state to the extended state. Therefore, in this state, the lens barrel unit L is in the extended state, and the light emitting unit 1 is in the use state.

  FIG.1 (c) has shown the state which moved the light emission unit 1 from the use state to the accommodation state by manual operation from the state shown in FIG.1 (b). In this state, the lens barrel unit L is in the extended state, and the light emitting unit 1 is in the retracted state. FIG. 1D shows a state where the light emitting unit 1 is moved from the housed state to the used state by manual operation from the state shown in FIG. In this state, the lens barrel unit L is retracted, and the light emitting unit 1 is in use.

  As shown in FIGS. 1C and 1D, the light emitting unit 1 is used by manual operation regardless of the state of the lens barrel unit L even when the light emitting unit interlocking switching lever 3 is switched to interlocking ON. And can be moved between storage states.

  The digital camera of the present embodiment can be brought into the state of FIG. 1C by manual operation from the state of FIG. When the power is turned off in the state of FIG. 1C, the light emitting unit 1 is in the housed state and is in the state of FIG. The digital camera of this embodiment can be changed from the state shown in FIG. 1A to the state shown in FIG. 1D by manual operation.

  The operation when the light emitting unit interlocking switching lever 3 is switched to interlocking off will be described with reference to FIGS.

  In FIG. 1 (e), the light emitting unit interlocking switching lever 3 is switched from the state shown in FIG. 1 (a) to the interlocking OFF by moving the light emitting unit interlocking switching lever 3 in the direction of arrow H in FIG. 1 (e). It is done. In the state illustrated in FIG. 1E, the lens barrel unit L is in the retracted state, and the light emitting unit 1 is in the retracted state. FIG. 1 (f) shows a state where the power is turned on from the state shown in FIG. 1 (e) by operating the power button 4. When the power button 4 is operated, the digital camera is switched from the imaging disabled state to the imaging enabled state, and the lens barrel unit L moves from the retracted state to the extended state. Since the light emitting unit interlocking switching lever 3 is in an interlocking off state, the light emitting unit 1 remains in the retracted state even when the lens barrel unit L moves from the retracted state to the extended state.

  In the digital camera of this embodiment, even if the light emitting unit interlocking switching lever 3 is switched to the interlocking off state, the light emitting unit 1 can be manually operated between the use state and the retracted state regardless of the state of the lens barrel unit L. You can move with. That is, even in the state illustrated in FIGS. 1E and 1F, the light emitting unit 1 can be moved between the use state and the storage state by manual operation.

  In the digital camera of this embodiment, the light emitting unit 1 can be moved between the use state and the housed state by a manual operation regardless of whether the light emitting unit interlocking switch lever 3 is switched to interlocking on or interlocking off. .

  FIG. 2 is an exploded perspective view of the lens barrel unit L of the digital camera.

  The lens barrel unit L includes a first group lens, a second group lens, and a third group lens (not shown). The first group lens is held by the first group lens holder 10, and the second group lens is held by the second group lens holder 11. The linear guide plate 12 is formed with a first group guide rod 13 that supports the first group lens holder 10 so as to be movable in the optical axis direction. The first group guide rod 13 is engaged with a groove (not shown) formed in the inner surface of the first group lens holder 10 and extending in the optical axis direction. Similarly, the linear guide plate 12 is integrally formed with a second group guide rod 15 that supports the second group lens holder 11 so as to be movable in the optical axis direction. The second group guide rod 15 engages with a second group linear advance hole 14 provided on the outer periphery of the second group lens holder 11, and supports the second group lens holder 11 so as to be movable in the optical axis direction.

  Accordingly, the first group lens holder 10 and the second group lens holder 11 are guided to move in the optical axis direction by the first group guide rod 13 and the second group guide rod 15 formed on the rectilinear guide plate 12. A plurality of protrusions 16 are formed on the outer edge portion of the flange portion of the rectilinear guide plate 12. The projections 16 are respectively engaged with a plurality of grooves 18 extending in the optical axis direction provided on the inner surface of the fixed cam ring 17 so that the linear guide plate 12 is supported so as to be movable in the optical axis direction.

  A cam follower 20 is formed on the outer peripheral surface of the movable cam ring 19 so as to divide the outer peripheral surface into three equal parts. The cam follower 20 is cam-engaged with three cams 21 of the same shape formed on the inner surface of the fixed cam ring 17. As a result, the cam follower 20 traces the cam 21 as the moving cam ring 19 rotates, and the moving cam ring 19 moves in the optical axis direction while rotating.

  Further, when the hook 23 of the rectilinear guide plate 12 is engaged with the engagement groove 22 provided at the rear end portion of the inner peripheral surface of the movable cam ring 19, the rectilinear guide plate 12 rotates with respect to the movable cam ring 19. Engage possible. Thereby, along with the movement of the movable cam ring 19 in the optical axis direction, the linear guide plate 12 also moves in the optical axis direction.

  A first group cam follower 24 is formed on the outer peripheral surface portion of the first group lens holder 10 so as to divide the outer peripheral surface into three equal parts. The first group cam follower 24 is cam-engaged with three first group cams 25 of the same shape provided on the inner peripheral surface of the movable cam ring 19. As a result, the first group cam follower 24 traces the first group cam 25 as the moving cam ring 19 rotates. Further, since the first group lens holder 10 is guided so as to move in the optical axis direction, the first group lens holder 10 is adjusted in accordance with the displacement amount of the first group cam 25 in the optical axis direction as the movable cam ring 19 rotates. Move.

  A second group cam follower 26 is formed on the outer peripheral surface of the second group lens holder 11 so as to divide the outer peripheral surface into three equal parts. The second group cam follower 26 is cam-engaged with three second group cams 27 of the same shape provided on the inner peripheral surface of the movable cam ring 19. As a result, the second group cam follower 26 traces the second group cam 27 as the moving cam ring 19 rotates. Further, since the second group lens holder 11 is guided to move in the optical axis direction, the second group lens holder 11 is adjusted in accordance with the displacement amount of the second group cam 27 in the optical axis direction as the movable cam ring 19 rotates. Move.

  A drive pin 28 is formed on the outer peripheral surface of the movable cam ring 19 so as to divide the outer peripheral surface into three equal parts. The drive pin 28 protrudes from the outer peripheral surface of the fixed cam ring 17 through a cam hole 29 penetrating from the inner peripheral surface of the fixed cam ring 17 to the outer peripheral surface. The cam 21 and the cam hole 29 have the same shape, and the drive pin 28 traces the cam hole 29 and keeps protruding from the cam ring 17 with respect to the rotational feeding movement of the movable cam ring 19 with respect to the fixed cam ring 17. .

  A drive ring 30 as a drive member is fitted to the outer peripheral surface of the fixed cam ring 17 and is rotatably supported. Grooves 31 extending in the optical axis direction are arranged on the inner peripheral surface of the drive ring 30 so as to be divided into three equal parts, and the drive pins 28 engage with the grooves 31, respectively. Thereby, the rotation of the drive ring 30 is transmitted to the movable cam ring 19 via the groove 31 and the drive pin 28.

  In this way, the first group lens holder 10, the second group lens holder 11, the rectilinear guide plate 12, the fixed cam ring 17, the movable cam ring 19, and the drive ring 30 are integrated and operate in cooperation with each other. The integrated parts are assembled into the lens barrel base 32. Further, the image sensor holder 33 holding the image sensor is fixed together with the lens barrel base 32 so as to sandwich the flange portion of the fixed cam ring 17.

  The drive source 44 of the lens barrel unit L is an electromagnetic motor that converts electric power into power. The power of the drive source 44 is transmitted to the drive ring gear 46 formed on the outer peripheral surface of the drive ring 30 via the gear train 45. Thereby, the drive ring 30 can be rotated by energizing the drive source 44.

  The lens barrel base 32 holds the drive source 44 and the gear train 45, and holds a slider 37 as a moving member so as to be movable in the optical axis direction. The slider 37 is guided by a slider shaft 38 held by the lens barrel base 32, and can move in the optical axis direction on the lens barrel base 32. The slider 37 is formed with a strobe follower 39 as a follower that can advance and retreat inside the slider 37, and the strobe follower 39 is urged by a compression spring 40 in a direction protruding from the slider 37.

  A first strobe cam 30 a, a second strobe cam 30 b, and a third strobe cam 30 c that can be engaged with the strobe follower 39 are formed on the outer peripheral surface of the drive ring 30. When the strobe follower 39 is engaged with the first strobe cam 30a, the drive ring 30 rotates, so that the slider 37 moves on the lens barrel base 32 in the optical axis direction.

  FIG. 3 is a diagram illustrating the lens barrel unit L. FIG. FIG. 3A is an external perspective view of the lens barrel unit L. FIG. In the state of FIG. 3A, the lens barrel unit L is in a retracted state. FIG. 3B is an external front view of the lens barrel unit L in the state of FIG. 3C is a cross-sectional view of the lens barrel unit L taken along the line AA in FIG.

  As shown in FIG. 3A, a U-shaped portion 37a is formed on the slider 37, and is formed on the light emitting unit interlocking switching lever 3 described later when the light emitting unit interlocking switching lever 3 is switched to interlocking on. The protrusion 3c is sandwiched. As shown in FIG. 3C, the slider 37 is formed with a hole portion that is substantially perpendicular to the outer peripheral surface of the drive ring 30 in a state where the slider 37 is supported by the slider shaft 38. A strobe follower 39 and a compression spring 40 are inserted. In the state of FIG. 3C, the strobe follower 39 is engaged with the first strobe cam 30a.

  FIG. 4A is an exploded perspective view of the light emitting unit 1 of the digital camera.

  The xenon tube 401 is electrically connected to the flexible wiring board 403 by a lead wire 402. The flexible wiring board 403 is electrically connected to a strobe board 404 that performs light emission control. The reflective shade 405 collects the light from the xenon tube 401. The xenon tube rubber 406 insulates the terminal portion of the xenon tube 401 and urges the xenon tube 401 toward the reflection shade 405. The prism panel 407 emits light from the xenon tube 401 and the reflective shade 405 to a desired range.

  The light emitting unit 1 is configured as follows. A xenon tube 401 having a xenon tube rubber 406 inserted between both ends is sandwiched between the prism panel 407 and the reflecting shade 405 and inserted into the strobe holder 408. The soft xenon tube rubber 406 is assembled while being pressed into the strobe holder 408, whereby the prism panel 407, the reflective shade 405, and the xenon tube 401 with the xenon tube rubber 406 inserted at both ends are fixed to the strobe holder 408. After the lead wire 402 is soldered to both poles of the xenon tube 401, the light emitting unit interlocking switching lever 3 is inserted into the notch 2a of the strobe cover 2. With the light emitting unit interlocking switch lever 3 inserted into the notch 2a of the strobe cover 2, the strobe cover 2 is put on the strobe holder 408 so as to cover it and fixed with screws. This is the light emitting unit 1.

  The strobe shaft 302 is inserted into the strobe base 301, the strobe cover 2 and the lever 3 of the light emitting unit 1. Accordingly, the light emitting unit 1 is supported by the strobe shaft 302 so as to be rotatable with respect to the strobe base 301. A shaft 410 that hooks one end of the toggle spring 409 is press-fitted into the strobe holder 408. The other end of the toggle spring 409 is hooked on a shaft 301 a provided in the strobe base 301. The toggle spring 409 functions as a biasing member that biases the light emitting unit 1 to the use state and the storage state with the strobe shaft 302 as a rotation center.

  The light emitting unit interlocking switching lever 3 is formed with a hole 3a, a protrusion 3b, a protrusion 3c, and an operation portion 3d. The hole 3 a of the light emitting unit interlocking switching lever 3 is fitted into the strobe shaft 302, and the protrusion 3 b of the light emitting unit interlocking switching lever 3 is engaged with the groove 408 b formed in the strobe holder 408. At this time, the operation unit 3 d of the light emitting unit interlocking switch lever 3 is exposed from the notch 2 a of the strobe cover 2. The user of the digital camera can operate the operation unit 3d exposed from the notch 2a. As a result, the light emitting unit interlocking switching lever 3 rotates together with the light emitting unit 1, and the user moves in the axial direction of the strobe shaft 302 within the range of the notch 2a of the strobe cover 2 to perform the switching operation. be able to.

  The flexible wiring board 403, the strobe board 404 and the strobe condenser 412 are attached to the attachment member 411. The strobe base 301 is also attached to the attachment member 411 with screws.

  A lever type detection switch 403a is mounted on the flexible wiring board 403, and detects whether the light emitting unit 1 is in use or in a storage position. The lever-type detection switch 403a is disposed so that the lever portion protrudes from the hole 411a provided in the attachment member 411. Therefore, when the light emitting unit 1 is in the retracted state, the protrusion 408a of the strobe holder 408 pushes the lever portion of the detection switch 403a. On the other hand, when the light emitting unit 1 is in use, the protrusion 408a does not contact the lever portion of the detection switch 403a. Only when the detection switch 403a detects that the light-emitting unit 1 is in use, the digital camera controls the light-emitting unit 1 to emit light.

  4B and 4C are diagrams for explaining the switching operation of the light emitting unit interlocking switching lever 3. FIG.

  FIG. 4B illustrates a state in which the light emitting unit interlocking switching lever 3 is moved in the direction of arrow G in the drawing. At this time, the light emitting unit interlocking switching lever 3 is switched to interlocking on. FIG. 4C illustrates a state in which the light emitting unit interlocking switching lever 3 is moved in the direction of arrow H in the drawing. At this time, the light emitting unit interlocking switching lever 3 is switched to interlocking off.

  FIG. 5 is a diagram illustrating the light emitting unit 1 of the digital camera. FIG. 5 illustrates a state where the light emitting unit interlocking switching lever 3 is in the interlocking on position. In FIG. 5, the lens barrel base 32, the attachment member 411, and the like are omitted. As described above, when the drive ring 30 rotates, the strobe follower 39 traces the first strobe cam 30a, and the slider 37 moves in the optical axis direction. The light emitting unit 1 is supported so as to be rotatable with respect to the strobe base 301.

  When the light emitting unit interlocking switching lever 3 is switched to interlocking on, the protrusion 3 c formed on the light emitting unit interlocking switching lever 3 is positioned at the U-shaped portion 37 a formed on the slider 37. On the other hand, when the light emitting unit interlocking switching lever 3 is switched to interlocking off, the protrusion 3 c formed on the light emitting unit interlocking switching lever 3 retracts from the U-shaped portion 37 a formed on the slider 37.

  Therefore, when the light emitting unit interlocking switching lever 3 is switched to interlocking ON, the slider 37 and the light emitting unit 1 are engaged. On the other hand, when the light emitting unit interlocking switching lever 3 is switched to interlocking on, the engagement between the slider 37 and the light emitting unit 1 is released. The light emitting unit interlocking switching lever 3 functions as a switching member that switches between the engaged state and the disengaged state.

  As the lens barrel unit L moves from the retracted state to the extended state and from the extended state to the retracted state, the slider 37 moves in the optical axis direction. At this time, when the light emitting unit interlocking switching lever 3 is switched to interlocking on and the protrusion 3c is positioned at the U-shaped portion 37a formed on the slider 37, the slider 37 moves in the optical axis direction, so The wall 37a1 or the wall 37a2 of the portion 37a pushes the protrusion 3c. Therefore, the light emitting unit 1 moves from the housed state to the used state in conjunction with the operation of moving the lens barrel unit L from the retracted state to the extended state. Then, in conjunction with the movement of the lens barrel unit L from the extended state to the retracted state, the light emitting unit 1 moves from the use state to the housed state.

  When the light emitting unit interlocking switching lever 3 is switched off and the protrusion 3c is retracted from the U-shaped portion 37a, even if the slider 37 moves in the optical axis direction, the U-shaped portion 37a formed on the slider 37 The wall 37a1 or the wall 37a2 does not push the protrusion 3c. Therefore, even if the lens barrel unit L moves from the retracted state to the extended state, or moves from the extended state to the retracted state, the light emitting unit 1 does not interlock with the movement of the lens barrel unit L. When the light emitting unit interlocking switching lever 3 is switched to interlocking off, the light emitting unit 1 moves between the housed state and the used state only by manual operation.

  The interlocking operation between the lens barrel unit L and the light emitting unit 1 will be described below.

  FIG. 6 is a diagram illustrating an operation in which the light emitting unit interlocking switching lever 3 is switched to interlocking on and the light emitting unit 1 moves between the use state and the storage state. Since the light emitting unit interlocking switching lever 3 is switched to interlocking on, the protrusion 3c formed on the light emitting unit interlocking switching lever 3 is located at the U-shaped portion 37a.

  FIG. 6A shows a storage state in which the light emitting unit 1 is stored. As shown in FIG. 6A, in this state, the protrusion 3c is not in contact with any wall of the U-shaped portion 37a, but the light emitting unit 1 is urged by the toggle spring 409 in the direction of being stored. Therefore, the light emitting unit 1 can hold the stored state.

  FIG. 6B shows a state in which the slider 37 has moved in the arrow Q direction from the state of FIG. In this state, the wall 37a2 of the U-shaped portion 37a comes into contact with the protrusion 3c, and moves the light emitting unit 1 to the use state against the urging force of the toggle spring 409.

  When the light emitting unit 1 is moved from the state of FIG. 6B to the point where the slider 37 reverses the direction of the urging force of the toggle spring 409, the urging direction of the toggle spring 409 is reversed, and the light emitting unit 1 is in use. It is energized in the direction of. FIG. 6C shows a state where the light emitting unit 1 is in use. At this time, the projection 3c is not in contact with any wall of the U-shaped portion 37a. However, since the light emitting unit 1 is biased in the direction of use by the toggle spring 409, the light emitting unit 1 is not in use. Can hold.

  Thus, by moving the slider 37 in the optical axis direction, the light emitting unit 1 moves from the housed state to the used state. When the light emitting unit 1 is moved from the use state to the housed state, the slider 37 may be moved in the left direction in the drawing from the state of FIG.

  When the light emitting unit interlocking switching lever 3 is switched to interlocking off, the protrusion 3c formed on the light emitting unit interlocking switching lever 3 is retracted from the U-shaped portion 37a, and therefore will be described with reference to FIGS. The interlocking relationship between the slider 37 and the protrusion 3c is not established.

  FIG. 7 is a view for explaining three cam shapes formed on the drive ring 30.

  FIG. 7A is a front view and a side view of the drive ring 30. FIG.7 (b) is BB sectional drawing of Fig.7 (a). FIG. 7C is an enlarged view of a portion where the drive ring 30 is expanded and the first strobe cam 30a, the second strobe cam 30b, and the third strobe cam 30c are formed.

  FIG. 8 is a diagram for explaining the operation of the light emitting unit 1.

  FIG. 8A shows the state of the light emitting unit 1 when the digital camera of this embodiment is in the state of FIG. FIG. 8B shows the state of the light emitting unit 1 when the digital camera of this embodiment is in the state of FIG. FIG. 8C shows the state of the light emitting unit 1 when the digital camera of this embodiment is in the state of FIG. FIG. 8D shows a state of the light emitting unit 1 when the digital camera of the present embodiment is in the state of FIG.

  As shown in FIGS. 7A to 7C, the drive ring 30 includes a first strobe cam 30a as a first cam, a second strobe cam 30b as a second cam, and a third cam. The third strobe cam 30c is formed. The first strobe cam 30a is a cam that brings the light emitting unit 1 from the housed state to the used state when the lens barrel unit L is extended from the retracted state. The first strobe cam 30a is a cam for bringing the light emitting unit 1 from the use state to the retracted state when the lens barrel unit L changes from the extended state to the retracted state. Therefore, when the light emitting unit 1 changes between the state shown in FIG. 8A and the state shown in FIG. 8B, the strobe follower 39 of the slider 37 traces the first strobe cam 30a.

  When the lens barrel unit L is in the extended state and the light emitting unit 1 is in the retracted state, the second strobe cam 30b moves the lens barrel unit L from the extended state to the retracted state while the light emitting unit 1 is in the retracted state. It is a cam to make. In addition, when the lens barrel unit L changes from the retracted state, the second strobe cam 30b presses the light emitting unit 1 and keeps the lens barrel unit L from the retracted state while being retracted. It is a cam. Therefore, when the light emitting unit 1 changes between the state shown in FIG. 8C and the state shown in FIG. 8A, the strobe follower 39 of the slider 37 traces the second strobe cam 30b.

  In the third strobe cam 30c, when the lens barrel unit L is retracted and the light emitting unit 1 is in use, the lens barrel unit L is extended from the retracted state while the light emitting unit 1 remains in use. It is a cam to make. In addition, when the lens barrel unit L changes from the extended state to the retracted state, the third strobe cam 30c presses the light emitting unit 1 and keeps the lens barrel unit L from the extended state to the retracted state. It is a cam. Therefore, when the light emitting unit 1 changes between the state shown in FIG. 8B and the state shown in FIG. 8D, the strobe follower 39 of the slider 37 traces the third strobe cam 30c.

  7C, when the lens barrel unit L shown in FIG. 8A is in the retracted state and the light emitting unit 1 is in the retracted state, the strobe follower 39 of the slider 37 is positioned at the position 30a1. When the lens barrel unit L shown in FIG. 8B is in the extended state as the extended state and the light emitting unit 1 is in the use state, the strobe follower 39 of the slider 37 is positioned at the position 30a2. When the lens barrel unit L is in the telephoto state as the extended state and the light emitting unit 1 is in use, the strobe follower 39 of the slider 37 is located at the position 30a3. The first strobe cam 30a moves the light emitting unit 1 between the housed state and the used state between the position 30a1 and the position 30a2, and the cam lift is almost zero between the position 30a2 and the position 30a3. Is set.

  As shown in FIG. 8B, when the strobe follower 39 of the slider 37 is positioned at the position 30a2, if the light emitting unit 1 is brought into the housed state by manual operation, the state shown in FIG. 8C is obtained. At this time, the strobe follower 39 releases the engagement with the first strobe cam 30a and engages with the second strobe cam 30b at the position 30b2. Similarly, when the light-emitting unit 1 is placed in the retracted state by manual operation when the strobe follower 39 is located at the position 30a3, the strobe follower 39 releases the engagement with the first strobe cam 30a. The strobe follower 39 engages with the second strobe cam 30b at the position 30b3.

  FIG. 9 is a diagram illustrating an operation when the light emitting unit 1 is manually operated. FIG. 9A shows a state in which the strobe follower 39 of the slider 37 is located at the position 30a2. When the light emitting unit 1 is housed by manual operation in this state, a force in the direction of the arrow F1 acts on the slider 37 as shown in FIG. 9B, and the strobe follower 39 resists the biasing force of the compression spring 40. And move in the direction of arrow P. That is, the strobe follower 39 is retracted inside the slider 37.

  As a result, the strobe follower 39 releases the engagement with the first strobe cam 30a, and the slider 37 moves in the direction of arrow F1. When the state shown in FIG. 9C is reached, the strobe follower 39 is inserted into the second strobe cam 30b by the urging force of the compression spring 40. At this time, when the strobe follower 39 is inserted into the second strobe cam 30b, the tip of the strobe follower 39 slides on the slope of the second strobe cam 30b, so that the force in the direction of arrow F1 is applied to the slider 37. Works. Then, as shown in FIG. 9D, the second strobe cam 30b is engaged. Thus, since the strobe follower 39 advances and retreats in the hole portion of the slider 37 that is substantially perpendicular to the outer peripheral surface of the drive ring 30, it is possible to engage and disengage the cam without stress.

  When the lens barrel unit L changes from the extended state to the retracted state when the strobe follower 39 engages with the second strobe cam 30b, the strobe follower 39 moves to the right end of the second strobe cam 30b shown in FIG. Trace until. Then, the strobe follower 39 releases the engagement with the second strobe cam 30b, proceeds in the direction of arrow B1 in FIG. 7C, engages with the first strobe cam 30a, and is positioned at the position 30a1. .

  When the strobe follower 39 is positioned at the position 30a1, the lens barrel unit L is changed from the retracted state to the wide state while the light emitting unit 1 is pushed in and stored. At this time, the strobe follower 39 releases the engagement with the first strobe cam 30a and proceeds in the direction of arrow B2 in FIG. The strobe follower 39 engages with the second strobe cam 30b and is positioned at the position 30b2.

  As shown in FIG. 8 (a), when the strobe follower 39 is located at the position 30a1, when the light emitting unit 1 is put into use by manual operation, the state shown in FIG. 8 (d) is obtained. At this time, the strobe follower 39 releases the engagement with the first strobe cam 30a and engages with the third strobe cam 30c at the position 30c1. If the lens barrel unit L is changed from the retracted state to the wide state when the strobe follower 39 is located at the position 30c1, the strobe follower 39 releases the engagement with the third strobe cam 30c and proceeds in the direction of the arrow C1. The strobe follower 39 engages with the first strobe cam 30a and is positioned at the position 30a2.

  When the strobe follower 39 is located at the position 30a2, the lens barrel unit L is changed from the wide state to the retracted state while the light emitting unit 1 is pressed and kept in use. At this time, the strobe follower 39 releases the engagement with the first strobe cam 30a and proceeds in the direction of arrow C2 in FIG. The strobe follower 39 engages with the third strobe cam 30c and is positioned at the position 30c1.

  In this embodiment, the first strobe cam 30a and the second strobe cam 30b are not connected to each other, and the first strobe cam 30a and the third strobe cam 30c are not connected to each other. For example, when the first strobe cam 30a and the second strobe cam 30b are connected, the strobe follower 39 is located at the position 30b2 when the strobe follower 39 is changed from the position 30a1 to the position 30a2. End up. That is, the first strobe cam 30a is not traced and the second strobe cam 30b is traced. For this reason, in this embodiment, the first strobe cam 30a and the second strobe cam 30b are separated from each other, and the first strobe cam 30a and the third strobe cam 30c are separated.

  FIG. 10 is a rear oblique view of the digital camera of this embodiment. The back surface of the digital camera of this embodiment is covered with a rear cover 1001, and a projection 1001 a is formed in a region adjacent to the light emitting unit 1 of the rear cover 1001. FIG. 10A illustrates a state in which the lens barrel unit L is in the retracted state, the light emitting unit 1 is in the retracted state, and the light emitting unit interlocking switching lever 3 is interlocked. In the state of FIG. 10A, the operation unit 3 d of the light emitting unit interlocking switch lever 3 is exposed from the notch 2 a of the strobe cover 2. Accordingly, the operation unit 3d of the light emitting unit interlocking switching lever 3 is in a state that can be operated by the user, and the user can switch from interlocking on to interlocking off by moving the operating unit 3d in the direction of arrow H.

  FIG. 10B shows a state in which the light emitting unit 1 has been moved from the state illustrated in FIG. When the light emitting unit 1 is moved to the use state, the projection 1001a of the rear cover 1001 covers the operation portion 3d of the light emitting unit interlocking switching lever 3 and the notch 2a of the strobe cover 2 as shown in FIG. Accordingly, the operation unit 3d of the light emitting unit interlocking switching lever 3 is in an inoperable state by the user, and the user cannot perform the switching operation of the light emitting unit interlocking switching lever 3.

  In the digital camera of this embodiment, the slider 37 moves in the direction of arrow Q shown in FIG. 6 in conjunction with the movement of the lens barrel unit L from the retracted state to the extended state. When the light emitting unit interlocking switching lever 3 is switched from interlocking off to interlocking on when the lens barrel unit L is in the extended state, the protrusion 3c formed on the light emitting unit interlocking switching lever 3 is a U-shaped portion 37a of the slider 37. I can't get inside. The slider 37 has a wall portion 37b. When the light emitting unit interlocking switching lever 3 is switched from interlocking off to interlocking on when the lens barrel unit L is in the extended state, the projection 3c formed on the light emitting unit interlocking switching lever 3 is a wall formed on the slider 37. It contacts the part 37b. As a result, when the lens barrel unit L is in the extended state, the light-emitting unit interlocking switching lever 3 cannot be switched from interlocking OFF to interlocking ON.

  Therefore, the switching operation of the light emitting unit interlocking switching lever 3 can be performed only when the lens barrel unit L is in the retracted state and the light emitting unit 1 is in the retracted state.

  According to this embodiment, the light emitting unit 1 is operated in conjunction with the lens barrel unit, the state in which the light emitting unit 1 is moved between the use state and the housed state, and the manual operation without being interlocked with the lens barrel unit. Can be switched between a use state and a storage state.
