Description

The present invention relates to a light emitting device such as a strobe unit mounted in an imaging device such as a digital camera, and an imaging device including the light emitting device.

As a small-sized digital camera or the like having a relatively large diameter lens barrel, in order to prevent so-called vignetting in which the strobe light is blocked by the tip of the lens barrel and does not reach the subject, a pop-up type strobe shown in FIG. Those equipped with a unit are known.

The pop-up type strobe unit shown in FIG. 8 has a movable member 3 having a light emitting portion 3a, a light emitting portion projecting the movable member 3 from the storage position (FIG. 8A) in the camera body 1 and the upper surface of the camera body 1. And a movement mechanism for moving it to and from the position (FIG. 8C). The moving mechanism has an arm member 4 that connects the movable member 3 and the camera body 1, and the base end of the arm member 4 is rotatably supported by the camera body 1 via a rotation shaft 4a. A movable member 3 is rotatably supported at the tip of 4 via a rotation shaft 4b. The arm member 4 is biased toward the front side (subject side: left side in the drawing) of the camera body 1 by a spring or the like, and the movable member 3 is biased toward the back side of the camera body 1 by a spring or the like. ..

However, in the strobe unit shown in FIG. 8, when the display unit 2 rotatably supported on the rear side of the camera body 1 is arranged so as to project above the camera body 1 with the display surface 2a facing the subject side when taking a selfie or the like. The movable member 3 may interfere with the display surface 2a during the pop-up operation.

That is, when the movable member 3 moves from the storage position to the light emitting position, the arm member 4 is rotated toward the subject side of the camera body 1 by the biasing force of the spring or the like, but the movable member 3 is biased by the spring or the like. Thus, the arm member 4 is rotated toward the back side of the camera body 1. Therefore, when the movable member 3 rotates toward the back side of the camera body 1 at a position where the tip of the arm member 4 approaches the display surface 2a, the movable member 3 is displayed in the H portion as shown in FIG. 8B. It may interfere with the surface 2a.

On the other hand, using a four-bar linkage, a follower provided on one of the plurality of pivots connecting the link members of the four-bar linkage is provided along a cam hole formed in the camera body. There has been proposed a technique for moving the movable member from the storage position to the light emitting position by moving the movable member.

In this proposal, since the movable member is supported by using the four-bar linkage, it is possible to move the movable member from the storage position to the light emitting position while keeping the movable member substantially horizontal. Therefore, it is possible to prevent the movable member from interfering with the display surface of the display unit when the movable member moves from the storage position to the light emitting position.

Further, in this proposal, the movable member is detachably locked to the lock plate at the storage position. The lock plate engages with the restriction portion of the movable member in a state of being elastically deformed, and holds the movable member in the storage position while biasing the movable member toward the front side of the camera body. Then, when the movable member moves to the light emitting position by the biasing force of the spring or the like, the lock plate returns to the natural state by the control portion of the movable member getting over. This makes it possible to prevent the movable member from rattling at the storage position and to prevent the movable member from swinging to the back side of the camera body when the movable member moves from the storage position to the light emitting position (Patent Reference 1).

JP, 2015-132720, A

However, in Patent Document 1 described above, since the movable member is supported and moved by the four-bar link mechanism, the number of parts such as the link member and the rotating shaft increases, and the strobe unit and thus the camera are increased in cost and size. Connect Further, since the follower provided on the rotation shaft of the link mechanism is moved along the cam hole formed in the camera body, the degree of freedom of rotation of the link member and the movable member interlocking with the link member is limited. For this reason, the amount of movement of the camera in the height direction and the optical axis direction toward the subject side when the movable member is popped up to the light emitting position cannot be increased.

Further, the elastic force of the lock plate must be set within a range that does not hinder the pop-up operation of the movable member and prevents rattling of the movable member at the storage position. Therefore, it is difficult to set the elastic force required for the lock plate, and the allowable tolerance of the elastic force is narrow, which makes the manufacturing difficult.

Further, since the lock plate must continue to generate an urging force that always urges the movable member in the storage position toward the front side of the camera body, it is not made of a thermoplastic resin or the like that is easily thermally deformed over time, but made of stainless steel or the like. It is necessary to use metal. For this reason, it is necessary to newly provide the lock plate as a dedicated part, and there is a problem that the cost of the strobe unit and the camera is increased and the size of the camera is increased due to an increase in the component cost and the assembly cost due to the addition of the number of parts.

Therefore, while maintaining the present invention, cost reduction and downsizing, when the light emitting device moves from the storage position to the light emitting position without interfering with the member on the back side of the image capturing device, the height direction and the light of the image capturing device can be reduced. An object of the present invention is to provide a technique for increasing the amount of movement of the light emitting device toward the subject side in the axial direction.

In order to achieve the above object, a light emitting device of the present invention includes a light emitting unit, and a movable member that moves between a housing position housed in a device body of an imaging device and a light emitting position protruding from the device body. A base member fixed to the inside of the apparatus main body, the base end being rotatably supported by the base member, and the movable member having a storage recess for storing the movable member at the storage position, A movable member is rotatably supported, and an arm member that moves the movable member between the storage position and the light emitting position by rotating with respect to the base member, and the movable member is the arm member. A first urging means for urging the device body in the direction of rotation toward the rear side, and an arm member in the direction of rotation of the device body in the direction toward the front side with respect to the base member. And a second urging means for moving the movable member and the base member to move the movable member from the storage position to the light emitting position by the urging force of the first urging means. A restricting unit that temporarily restricts the rotation of the movable member toward the back side of the device body is provided, and the movable member temporarily rotates toward the back side of the device body by the restricting unit. while being restricted, the front side of the apparatus body than when in the storage position is characterized that you tilt the bottom side of the apparatus body.

According to the present invention, while maintaining cost reduction and miniaturization, when the light emitting device moves from the stored position to the light emitting position without interfering with a member on the back side of the image capturing device, It is possible to increase the amount of movement of the light emitting device toward the subject side in the optical axis direction.

Further, a cam portion 24b is formed on one inner wall surface of the storage recess 24e in the axial direction of the rotating shaft 23 as shown in FIG. 2B, and the movable member 12 is shown in FIG. As shown, the cam follower 20a is provided at a position corresponding to the cam portion 24b. The cam follower 20a engages with the cam portion 24b when the movable member 12 moves from the stored position to the light emitting position.

A lock lever 33 is integrally provided on the strobe lever 106, and the lock lever 33 locks a locking claw 19b provided on the movable member 12 at a storage position of the movable member 12. Further, a strobe board 31 is provided on the lower portion of the back side of the strobe unit 10, and a connector 31a to which a flexible board 28 passing through the opening 24a of the base member 24 is electrically connected is mounted on the strobe board 31. Has been done.

As shown in FIG. 3A, the base member 24 and the arm member 11 are provided with an abutting portion 24d and an abutting portion 22d that abut each other. When the abutting portions 24d and 22d come into contact with each other, the arm member 11 is restricted from rotating further in the counterclockwise direction at the light emitting position shown in FIG. 3(a).

As shown in FIG. 3B, the movable member 12 and the arm member 11 are provided with an abutting portion 19c and an abutting portion 22a that abut each other. When the abutting portions 19c and 22a come into contact with each other, the movable member 12 is restricted from further rotating in the clockwise direction at the light emitting position shown in FIG.

As shown in FIGS. 3C and 3D, at the storage position of the movable member 12, the cam follower 20 a is stored inside the camera body 102. As shown in FIG. 3D, the cam follower 20 a provided on the movable member 12 and the cam portion 24 b provided on the inner wall portion of the storage recess 24 e of the base member 24 are the axial end portions of the rotating shaft 21 of the light emitting portion 15. It is located in a position that avoids the side area. As a result, the strobe unit 10 and thus the camera body 102 can be reduced in size in the width direction.

In the present embodiment, the light emitting unit 15 uses a xenon tube. A plurality of terminals 14a are provided on the back surface side of the light emitting unit 15, and each terminal 14a is connected to both electrodes of the xenon tube and the trigger coil (not shown) that form the light emitting unit 15 and soldered to the flexible substrate 28. It is fixed by attachment. As a result, electric power is supplied from the camera body 102 to the light emitting unit 15 through the flexible substrate 28. The flexible substrate 28 passing between the arm portion 22 of the arm member 11 and the protection portion 29 is led out into the inside of the movable member 12 from between the opening portion 19 a provided in the movable member 12 and the rotating shaft 21. .. In this embodiment, a xenon tube is used as the light emitting unit 15, but an LED or the like may be used instead of the xenon tube.

Next, the operation of the flash unit 10 will be described with reference to FIGS. 4 and 5. FIG. 4A is a side cross-sectional view of the strobe unit 10 when the movable member 12 is at the storage position as viewed from the front left side of the camera body 102. FIG. 4B is a side view of the strobe unit 10 when the movable member 12 is at the storage position, as viewed from the front right side of the camera body 102.

In the state shown in FIGS. 4A and 4B, the locking claw 19b of the movable member 12 is locked by the lock lever 33 integrated with the strobe lever 106. The lock lever 33 is biased by a coil spring 34 provided between the lock lever 33 and the base member 24 in a direction in which the movable member 12 is pulled into the storage position, and thus the movable member 12 is held in the storage position. R. At this time, the upper surface of the movable member 12 is a horizontal plane parallel to the optical axis of the camera body 102. Further, as shown in FIG. 4A, the gap between the cam follower 20a and the cam surface 24c of the cam portion 24b is narrowed, so that the rattling in the optical axis direction of the camera body 102 when the movable member 12 is stored. It suppresses contact.

When the strobe lever 106 is operated in a direction to release the lock between the lock lever 33 and the locking claw 19b against the biasing force of the coil spring 34, the biasing force of the spring 25 causes the arm member 11 to rotate about the rotation shaft 23. Then, the rotation starts in the clockwise direction of FIG. At the same time, the biasing force of the spring 26 causes the movable member 12 to start rotating in the counterclockwise direction in FIG.

FIG. 4C is a side sectional view of the strobe unit 10 immediately after the lock lever 33 and the locking claw 19b are released from the front left side of the camera body 102. FIG. 4D is a side view of the strobe unit 10 immediately after the lock lever 33 and the locking claw 19b are released from the front right side of the camera body 102.

In the state shown in FIGS. 4C and 4D, in the movable member 12, the cam follower 20a is brought into contact with the cam surface 24c of the cam portion 24b, so that the movable member 12 is centered around the rotation shaft 21 as shown in FIG. The counterclockwise rotation of the is temporarily restricted. Then, the movable member 12 performs a pop-up operation toward the light emitting position along the cam surface 24c in a state where the cam follower 20a is in contact with the cam surface 24c of the cam portion 24b.

When the movable member 12 moves to the light emitting position, the rotation of the movable member 12 is temporarily restricted by the engagement of the cam follower 20a and the cam portion 24b, so that the movable member 12 is moved from the storage position in FIG. 4A. The subject side (right side in FIG. 4C) is inclined to the bottom side (lower side) of the camera body 102. The forward tilt angle of the movable member 12 is set to an angle at which the movable member 12 does not interfere with the front-side upper end portion 108 of the camera body 102 with the pop-up operation.

Therefore, the movable member 12 that rotates in the counterclockwise direction in FIG. 4C around the rotation shaft 21 by the urging force of the spring 26 is temporarily stopped by the cam follower 20a and the cam portion 24b. It rotates in the clockwise direction of 4(c).

FIG. 5A is a side sectional view of the strobe unit 10 immediately before the cam follower 20 a of the movable member 12 is disengaged from the cam portion 24 b of the base member 24 as viewed from the front left side of the camera body 102.

In the state shown in FIG. 5A, the cam follower 20a is in contact with the cam portion 24b, and similarly to FIG. 4C, the movable member 12 is tilted forward with the subject side tilted to the lower side of the camera body 102. I keep my posture. At this time, the display unit 110 is arranged so as to project upward from the upper surface of the camera body 102 with the display surface 110a facing the subject side by being rotated about 180° in the opening direction (upward).

Here, the reason why the movable member 12 is tilted forward until just before the cam follower 20a is separated from the cam portion 24b is to widen the gap between the rear side of the movable member 12 and the display unit 110. Further, the rotation angle of the movable member 12 from the position where the cam follower 20a is disengaged from the cam portion 24b until the abutting portion 19c of the movable member 12 abuts against the abutting portion 22a of the arm member 11 (hereinafter referred to as rotation residual amount). This is to maximize the angle).

If the rotation residual angle of the movable member 12 is large, the time required for the abutting portion 19c to abut the abutting portion 22a becomes longer, and the rotation of the arm member 11 relative to the base member 24 toward the subject advances. It will be. As a result, the movable member 12 rotates to the back side of the camera body 102 at a position away from the display unit 110 toward the subject side, and thus the movable member 12 can be prevented from interfering with the display unit 110. ..

The cam follower 20a is engaged with the cam surface 24c of the cam portion 24b at the storage position of the movable member 12, and the cam surface 24c is provided in a region up to the front side upper end portion 108 of the base member 24. These arrangements enable the rotation of the movable member 12 by the cam followers 20a and the cam portions 24b to be as high as possible in the height direction of the camera body 102 while the movable member 12 moves from the storage position to the light emitting position. This is because.

Further, the cam followers are respectively provided on the side wall portion of the movable member 12 and the inner wall portion of the storage recessed portion 24e of the base member 24 within the height dimension of the light emitting unit 15 at the storage position of the movable member 12 substantially equal to the height dimension of the camera body 102. 20a and a cam portion 24b are arranged. Accordingly, the dimension of the strobe unit 10 in the height direction of the camera body 102 can be shortened, and the camera body 102 can be downsized.

If the cam follower 20a and the cam portion 24b are arranged on the rear surface of the movable member 12, the rear surface of the movable member 12 is inclined downward toward the rear surface side of the camera body 102. Must be deep inside. Therefore, the flash unit 10 becomes large in the height direction of the camera body 102.

FIG. 5B is a side sectional view of the strobe unit 10 in which the movable member 12 has moved to the light emitting position, as viewed from the front left side of the camera body 102.

In the state shown in FIG. 5B, in the arm member 11, the abutting portion 22d abuts the abutting portion 24d of the base member 24 in a state of being biased by the spring 25, and the arm member 11 further than that in FIG. Rotation in the clockwise direction is restricted. On the other hand, the movable member 12 is rotated until the cam follower 20a is separated from the cam portion 24b immediately after being shown in FIG. 5A and the abutting portion 19c is abutted against the abutting portion 22a of the arm member 11 by the urging force of the spring 26. It rotates about the drive shaft 21 in the counterclockwise direction in FIG. As a result, the movement of the movable member 12 to the light emitting position is completed, and the state shown in FIG.

FIG. 5C shows the strobe unit 10 when the movable member 12 in the light emitting position is forcibly rotated to the rear side of the camera body 102 about the rotation shaft 23 with respect to the base member 24. FIG. 10 is a side sectional view as seen from the front left side of 102.

In the state shown in FIG. 5C, the movable member 12 is arranged at a position for causing the light emitting unit 15 to bounce and emit light obliquely upward on the subject side. The arm member 11 can freely rotate about the rotation shaft 23 within a predetermined angle between the storage position and the light emitting position. Further, the movable member 12 can freely rotate within a predetermined angle about the rotation shaft 21 with respect to the arm member 11 after the rotation restriction by the cam follower 20a and the cam portion 24b is released. is there.

When the movable member 12 is supported by a plurality of rotary shafts using a plurality of link mechanisms, the movable member 12 is difficult to operate only on a movement path determined with respect to the camera body 102, and the degree of freedom of the movement path. Is severely limited. In the present embodiment, the moving path of the movable member 12 is restricted by the cam follower 20a, the cam portion 24b, and the rotation shaft 21 until the rotation restriction by the cam follower 20a and the cam portion 24b is released from the storage position. Only.

Therefore, the movable member 12 is supported only by the rotation shaft 21 from the release of the rotation restriction by the cam follower 20a and the cam portion 24b to the light emitting position. Therefore, in a state where the rotation restriction of the movable member 12 is released, the photographer moves the arm member 11 and the movable member 12 within a predetermined rotation angle range about the rotation shaft 23 and the rotation shaft 21, respectively. The movable member 12 can be freely rotated to move to the bounce light emitting position described above.

When the upper surface portion of the movable member 12 is pushed in against the urging force of the spring 26 and the spring 25 from the state of FIG. 5B or 5C, the movable member 12 and the arm member 11 are moved to the state of FIG. It is stored in the storage position shown in. When the movable member 12 moves to the vicinity of the storage position shown in FIG. 4A, the locking lever 33 is locked by the locking claw 19b of the movable member 12, and the movable member 12 is retracted to the position shown in FIG. 4A.

As described above, in the present embodiment, the rotation residual angle of the movable member 12 is increased by the temporary rotation restriction by the cam follower 20a and the cam portion 24b, and the movable member 12 is separated from the display unit 110 toward the subject side. It is rotated to the back side of the camera body 102 at the open position. For this reason, when the movable member 12 moves from the storage position to the light emitting position, it is possible to avoid interference with the display unit 110 at the self-shooting position on the back side of the camera body 102.

Further, in the present embodiment, it is not necessary for the movable member 12 to have a plurality of rotation support portions using a plurality of link members. For this reason, not only the number of parts, the parts cost, and the assembly cost can be reduced, but also the flash unit 10 and thus the camera can be downsized.

In addition, in the present embodiment, since the plurality of rotation supporting portions using the plurality of link members are not used to support the movable member 12, it is not necessary to link the movable member 12 other than the arm member 11. Therefore, the degree of freedom in setting the light emitting position of the light emitting unit 15 is increased, and the light emitting unit 15 can be moved higher and further toward the subject side.

Further, in the present embodiment, the cam follower 20a can be integrally formed with a component of the movable member 12, and the cam portion 24b can be integrally formed with, for example, the base member 24 fixed to the camera body 102. it can. Therefore, it is possible to suppress an increase in the number of parts for providing the cam follower 20a and the cam portion 24b, the parts cost, and the assembly cost.

In addition, in the present embodiment, the cam follower 20a and the cam portion 24b need only have strength enough to repeatedly support the urging force of the spring 26 and can flexibly respond to changes in the urging force of the spring 26. , The freedom of design increases.

(Second embodiment)
Next, with reference to FIGS. 6 and 7, a digital camera equipped with a strobe unit, which is a second embodiment of the light emitting device of the present invention, will be described. It should be noted that parts that overlap or correspond to those of the above-described first embodiment will be described by assigning the same reference numerals to the respective drawings.

6A is a perspective view of the movable member 12 of the strobe unit 10 seen from the back side, FIG. 6B is an enlarged view of a main part of FIG. 6A, and FIG. 6C is a movable unit of the strobe unit 10. It is a perspective view explaining operation|movement when the member 12 is stored in a storage position.

In this embodiment, a cam follower 20b shown in FIG. 6 is used instead of the cam follower 20a of the first embodiment. The cam follower 20b is provided integrally with the movable member 12 at the same position as the cam follower 20a, but is different from the cam follower 20a in that the cam follower 20b is formed in a flexible cantilever shape. When it is pushed in the (direction), it can bend in the A direction. A chamfer 20c is formed at the tip of the cam follower 20b.

The movable member 12 rotates about the rotation shaft 21 with respect to the arm member 11. Therefore, when the upper surface of the movable member 12 is pushed in and the movable member 12 is housed in the housing recess 24e in a state in which the rotation restriction of the movable member 12 by the cam follower 20b and the cam portion 24b is released, the cam follower 20b has various configurations. It comes into contact with the upper surface of the cam portion 24b at various angles.

In FIG. 6C, the tip end of the cam follower 20b is in contact with the upper surface portion of the cam portion 24b of the base member 24. Since the chamfered portion 20c is provided at the tip of the cam follower 20b, even if the movable member 12 is further pushed, the chamfered portion 20c is pushed by the cam portion 24b and the cam follower 20b bends in the direction A of FIG. 6C. .. As a result, the movable member 12 can be pushed into the storage position and stored in the storage recess 24e without the cam follower 20b being caught by the cam portion 24b.

FIG. 7A is an enlarged view of the cam follower 20b and the cam portion 24b viewed from the arrow B direction in FIG. 6C. As shown in FIG. 7A, a chamfered portion 24f is formed at the inner corner of the upper end of the cam portion 24b. When the movable member 12 is pushed toward the storage position, the chamfered portion 20c of the cam follower 20b and the chamfered portion 24f of the cam portion 24b come into contact with each other. Then, the cam portion 24b having higher rigidity than the cam follower 20b is not deformed, and the tip end of the cam follower 20b having the cantilever structure bends in the direction A and retracts from the cam portion 24b.

FIG. 7B is a side view of the flash unit 10 when the movable member 12 is at the storage position, and FIG. 7C is a sectional view taken along the line CC of FIG. 7B. When the movable member 12 is completely pushed to the storage position, the cam follower 20b retracted in the A direction is not pushed by the cam portion 24b, and thus elastically returns to the original position as shown in FIG. 7C. , Is arranged to face the cam surface 24c.

That is, when the locking between the locking claw 19b and the lock lever 33 is released by operating the strobe lever 106 while the movable member 12 is in the storage position shown in FIG. 7B, the cam follower 20b retracts in the A direction. Without doing so, the cam portion 24b and the cam portion 24b function in the same manner as in FIGS.

At the storage position of the movable member 12 shown in FIG. 7B, no external force in the A direction is applied to the cam followers 20b of the movable member 12. Therefore, the movable member 12 can be integrally provided with the cam follower 20b that can be retracted in the direction A even when a material such as a thermoplastic resin that is easily thermally deformed by being left at a temperature is provided. Can be suppressed. Other configurations and operational effects are similar to those of the first embodiment.

The configuration of the present invention is not limited to those illustrated in the above embodiments, and materials, shapes, dimensions, forms, numbers, locations, etc. may be appropriately changed without departing from the gist of the present invention. It is possible.
