Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pop-up mechanism of a strobe device, and more particularly to a pop-up mechanism of a strobe device for popping up a strobe device from a non-irradiation position to an irradiation-possible position.

[0002]

2. Description of the Related Art Conventionally, various proposals have been made for a small camera or the like using a roll film having a width of 35 mm in which a strobe device for irradiating an auxiliary light for photographing is built in a camera body. And has been put to practical use.

In such a camera, when the camera is in a non-shooting state, for example, when the camera is carried or stored, the front surface of the photographing lens is shielded and protected. A device having a so-called pop-up mechanism in which a strobe device including a strobe light emitting unit and the like is moved to a protruding position protruding from the camera body and a storage position stored in the camera body in conjunction with an off operation or the like, For example, JP-A-6-242
497 and JP-A-8-286242 have been proposed.

[0004] Japanese Patent Application Laid-Open No. 6-242497 discloses that
There is disclosed a pop-up mechanism of a strobe device in which a strobe device is moved to a protruding position and a storage position with respect to a camera body in synchronization with operations of starting and stopping photographing. The pop-up mechanism includes an urging spring for urging a strobe device, one end of which is rotatably supported by the camera body and disposed in a protruding direction, and a strobe device against the urging force of the urging spring. It is constituted by an urging spring or the like for urging the storage position.

[0005] In addition, the moving device of the flash light emitting unit disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 8-286242 is linked to the opening operation of the lens barrier to move the lens barrel in the collapsed state to the initial position where photographing is possible. Then, the projection provided on the outer peripheral surface of the lens barrel acts on the rotating cam on the camera body side to rotate it, and the flash device is rotated by a spring member that rotates in conjunction with the cam. It is designed to be moved to the protruding position. According to this, the rotation angle (rotational movement amount) when the strobe device is protruded can be suppressed, a larger pop-up amount can be secured, and the camera can be further reduced in size.

In the above-mentioned JP-A-6-242497 and JP-A-8-286242, the pop-up mechanism of the strobe device is realized by using a spring member such as an urging spring. In some cases, the strobe device is made to pop up using the rotational force of a rotating lever that rotates in conjunction with the reciprocating operation of a taking lens barrel that moves from a retracted position to a photographing position.

[0007]

However, in a camera using the conventional means disclosed in the above-mentioned Japanese Patent Application Laid-Open Nos. 6-242497 and 8-286242, the light emission amount of the strobe device, that is, the guide number In order to increase the size, it is conceivable to design an irradiation opening such as a light emission window of a strobe device to secure a large area. However, simply increasing the area of the irradiation opening does not provide a sufficient amount of projection of the strobe device from the camera body, and the irradiation opening cannot be protruded from the camera body as necessary. As a result, part of the irradiation light emitted from the irradiation opening of the strobe device may be vignetted by the camera body. In this case, the irradiation light is wasted and good light distribution characteristics are also obtained. There is a problem that it cannot be obtained satisfactorily.

Therefore, in such a case, if the strobe device is designed so as to protrude more from the camera body and the moving amount of the strobe device from the camera body is increased, irradiation from the strobe device can be performed. Problems such as vignetting of light by the camera body and deterioration of light distribution characteristics can be solved.

However, considering a case where the amount of projection of the strobe device from the camera body is set to be large, for example, the above-mentioned JP-A-6-242497 and JP-A-8-286242.
In the means for popping up by a spring member as disclosed in Japanese Unexamined Patent Publication (Kokai) No. H05-209, there is a problem that the operation becomes unstable.

In the above-described means for popping up the flash device using the rotational force of the rotary lever, it is necessary to set a large rotation range (angle) of the rotary lever for moving the flash device and an amount of driving force thereof. Therefore,
There is a problem that the size of the camera itself incorporating the pop-up mechanism is increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to move a strobe device in a strobe device pop-up mechanism for popping up a strobe device from a non-irradiation position to an irradiation position. An object of the present invention is to provide a pop-up mechanism of a strobe device capable of popping up a strobe device at a position largely protruding from a camera body, while suppressing a moving amount of a driving member itself to be driven and with a smaller driving force. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. FIGS. 1, 2, and 3 are front views showing a camera having a pop-up mechanism of a flash device according to an embodiment of the present invention. FIG. 1 shows a state in which the flash device is in a storage position, and FIG. FIG. 3 shows a state in which the strobe device is at the first projecting position with the first operation, and FIG. 3 shows a state in which the strobe device is at the second projecting position with the second operation.

In the camera according to the present embodiment, as shown in FIGS. 1 to 3, a lens barrier 2 is slidably disposed at the center on the front side of a front cover 1 forming a part of the camera body. The lens barrier 2 is disposed on the front side of the camera by sliding along the direction of arrow X1 shown in FIG. 1 when the camera is not used (when not photographing), such as when carrying the camera or when storing the camera. The components such as the photographing optical system 5 and the finder window 6 are covered and protected. This non-photographing state is as shown in FIG.

On the other hand, when taking a photograph or the like with the camera, that is, when using the camera, the lens barrier 2 is slid along the direction of the arrow X2 shown in FIGS. A power switch (not shown) of the camera linked to the moving operation is turned on (ON), and a photographing optical system 5 and a finder window 6 disposed on the front side of the camera are opened to perform a photographing operation. It is possible to make it possible. The state in which this photographing operation is possible is as shown in FIG.

The photographing optical system 5 is constituted by a lens barrel or the like for holding a photographing lens. When the camera is not used (see FIG. 1), a power switch interlocked with the sliding operation of the lens barrier 2 In response to an OFF signal (not shown), a photographing prohibition operation is performed and the camera is collapsed and housed in the camera. On the other hand, when the camera is used (see FIG. 3), photographing is performed in response to an ON signal of the power switch. The permission operation is performed, and the operation is extended to the photographable position.

At one end on the top side of the camera,
A strobe housing 3, which is a main component of the strobe device, is disposed so as to be freely retractable. The strobe housing 3 is disposed on the right shoulder portion of the camera main body when viewed from the front, with the base portion rotatably supported by the camera main body, and is largely counterclockwise with respect to the camera main body when irradiation is possible. It takes a pop-up attitude that protrudes in a diagonal direction when the right shoulder rotates. The strobe housing 3 includes the lens barrier 2
A flash which can be irradiated with a flash (illumination light) by protruding from the camera body in accordance with an extension / retraction operation of the photographing optical system 5 performed in accordance with an on / off operation of a power switch interlocked with a sliding operation of the camera. It moves to a protruding position (see FIG. 3), which is an irradiation-possible position, and to a storage position (see FIG. 1), which is a non-irradiation position that is housed in the camera body and does not emit flash light. The operation when the strobe housing 3 moves between the storage position and the protruding position in the present embodiment is performed through a two-stage operation. That is, when the camera is not used, the strobe housing 3 of the present embodiment is in a storage position where it is stored in the camera body as shown in FIG. 1, and when the camera is used, the strobe housing 3 is moved from the storage position of FIG. After the operation (movement in the direction of arrow X3 shown in FIG. 2) is started and after passing through the first projecting position (see FIG. 2), the second operation (movement in the direction of arrow X4 shown in FIG. 3) is performed. As a result, an irradiation-possible position (second projecting position; see FIG. 3) protrudes greatly from the camera body.

The strobe housing 3 is formed of, for example, a xenon (Xe) discharge tube, a reflector, a light emitting window member, and the like, and the strobe device itself has a general structure conventionally used. Things. Further, on the upper surface side of the camera body, various operation members such as a release button 4 for instructing a photographing operation are arranged.

Next, the detailed configuration of the pop-up mechanism in the flash device of the present embodiment will be described below. FIG. 4 is an enlarged exploded perspective view showing a main part of only a main part of a strobe housing and a pop-up mechanism constituting a part of a strobe device provided in the camera of the present embodiment.

As shown in FIG. 4, a support member 7 which is a lever for rotatably supporting the flash housing 3 is disposed on the bottom side of the flash housing 3. This support member 7
Has one end 7a rotatably supported by a fixed portion (not shown) on the camera body side, for example, an inner wall surface of the front cover 1, and a support shaft 7b at the other end. 8 are provided. The support shaft 8 is rotatably supported by a flash support portion 3d on the lower surface side of the flash housing 3, thereby rotatably supporting the flash housing 3. Therefore, the strobe housing 3 is movably supported by the camera body via the support member 7.

An urging spring 10 for constantly urging the supporting member 7 toward the bottom surface of the flash housing 3 is provided on the supporting shaft 8.
Is wound, whereby the support member 7 is always in contact with the bottom surface of the flash housing 3 in the normal state.

The stroboscopic housing 3 is provided with an arm 9 integrally formed so as to protrude downward from the bottom surface side. A first driven portion 17 and a second driven portion 18 are formed at the tip of the arm portion 9, and the first and second driven portions 17 and 18 are connected to a first driven portion 17, which will be described later. The strobe housing 3 is driven by a driving lever 11 which is a rotating member having a driving unit (a first cam unit 15) and a second driving unit (a second cam unit 16) and constitutes a driving unit. The strobe housing 3 can be moved to a protruding position where it protrudes from the main body, that is, a flashable position, and a storage position where the strobe housing 3 is stored in the camera body, that is, a non-irradiation position.

On the other hand, on the camera body side, a first cam portion 15 as a first driving portion and a second cam portion 1 as a second driving portion are provided.
A drive lever 11 having a drive lever 6 is disposed at a position facing the arm 9 of the strobe housing 3. The drive lever 11 is, for example, within a predetermined range with respect to a fixing portion (not shown) of the main body portion forming a part of the camera body or a fixing portion (not shown) of the inner wall surface of the front cover 1. And is rotatably supported by the support shaft 12. The support shaft 12 has a cam groove 13a which rotates in conjunction with the extending / retracting operation of the photographing optical system 5, and a rotation shaft 13 constituting a driving means is integrally provided along the support shaft 12. Have been.
When the rotation shaft 13 rotates in one direction (the direction of the arrow X5 shown in FIG. 4) by the cam groove 13a, the drive lever 11 also rotates in the same direction in conjunction with the rotation.

On the other hand, a projection 5a is provided on the outer peripheral surface of the lens barrel of the photographing optical system 5, as shown in FIGS. Alternatively, the projection 5a comes into contact with the cam groove 13a of the rotating shaft 13 in accordance with the movement of the lens barrel in the optical axis direction when the collapsing operation is performed, and the projection 5a moves along the projection. As a result, the rotation shaft 13 rotates, and the driving lever 11 also rotates in the same direction in conjunction with the rotation.

The driving lever 11 is connected to the rotating shaft 1
3, the drive lever 11 is biasing means wound around the support shaft 12 and is driven by the biasing force of a biasing spring 14 which constitutes a part of the drive means. 4 (i.e., the direction of the arrow X5 shown in FIG. 4), i.e., in the direction of rotation of the rotation shaft 13 that rotates with the extending operation of the imaging optical system 5. The rotation shaft 13 is configured to receive the rotation shaft 13 via the rotation shaft 13. Thus, the drive lever 11 and the rotating shaft 13 are integrally rotated in one direction (the direction of the arrow X5 shown in FIG. 4).

When the lens barrel of the photographing optical system 5 is extended to be ready for photographing, the rotating shaft 13
The rotation in the other direction (the direction opposite to the X5 direction) is restricted by the engagement of the projection 5a with the cam groove 13a. Therefore, in this state, the rotation shaft 13 and the drive lever 11 rotate integrally in one direction (X5 direction) as described above, while rotating in the other direction (direction opposite to the X5 direction). ), The rotation shaft 13 is restricted in rotation and is in an immobile state, and the drive lever 11 is fixed with respect to the rotation shaft 13 against the urging force of the urging spring 14. It is configured to be able to rotate within the range.

As described above, only the drive lever 11 can be rotated in the other direction because the external force is applied to the strobe housing 3 at the projecting position. This is because the external force can be absorbed by the urging force of the urging spring 14.

As described above, the drive lever 11 has:
A first cam portion 15 which is a first driving portion which contacts and drives a contact surface of a first driven portion 17 provided at a tip portion of the arm portion 9; A second cam portion 16 as a second driving portion that contacts the inclined surface of the second driven portion 18 provided in the portion and drives the second inclined portion is integrally arranged.

The operation of the pop-up mechanism of the strobe device according to the above-described embodiment will be described below with reference to FIGS. 5 shows a state in which the strobe device is in the storage position (corresponding to the state in FIG. 1), FIG. 6 shows a state in which the strobe device is in the first projecting position (corresponding to the state in FIG. 2), and FIG. 4 shows a state (corresponding to the state of FIG. 3) in which the strobe device is at the second projecting position.

As described above, the pop-up mechanism of the strobe device of the present embodiment moves from the storage position in the camera body to the first projecting position by the first operation and then to the second projecting position by the second operation. The strobe device is made to pop up from the camera body by a series of operations.

That is, when the camera according to the present embodiment is not used, the lens barrier 2 is closed as shown in FIG. 1, and at this time, the strobe housing 3 of the strobe device is as shown in FIG. As shown in FIG. 5, the camera is stored in a storage position in the camera body. In this state,
The strobe housing 3 is urged toward the support member 7 by the urging force of the urging spring 10 wound around the support shaft 8.
The lower surface of one end 3b near the support portion supported by the support shaft 8 of the flash housing 3 and the lower surface of the free end 3a of the flash housing 3 are fixed to the fixing portions 20, 2 of the camera body, respectively.
1 and the strobe housing 3
Is positioned at the storage position.

When the strobe housing 3 is in the storage position as described above and the user of the camera sets the camera in a shooting preparation state for taking a photograph or the like, the lens barrier 2 is first shown in FIG. Slide in the direction of arrow X2. Then, in conjunction with this, a power switch (not shown) is turned on, and then the lens barrel of the photographing optical system 5 is extended toward the front of the camera. By this extending operation, the projection 5a of the lens barrel moves in a direction along the optical axis, that is, toward the front of the camera. At this time, since the protrusion 5a moves along the cam groove of the rotation shaft 13, the rotation shaft 13 is thereby rotated clockwise about the support shaft 12 (arrow X6 shown in FIG. 5). Direction). And
The first operation is started by rotating the drive lever 11 in the same direction in conjunction with the rotation of the rotation shaft 13.

That is, the first cam portion 1 of the drive lever 11
5 is a first driven portion 1 of the arm 9 of the strobe housing 3
7, and the first rotation shaft 13 and the drive lever 11 rotate in the X6 direction.
The cam section 15 drives the first driven section 17. Thus, the strobe housing 3 starts moving in the direction of arrow X3 shown in FIGS. At this time, the strobe housing 3 rotates together with the support member 7 formed integrally therewith. In other words, the support member 7 rotates clockwise about the one end 7a thereof, and at the same time, the strobe housing 3 rotates clockwise about the contact point of the free end 3a with the fixing portion 20 as the rotation center. To rotate. Then, the support portion 7b of the support member 7
Of the camera body (front cover 2), the flash housing 3 is positioned at the first protruding position, and a series of first operations is completed. I do.

When the drive lever 11 is further rotated in the same direction (clockwise, X6 direction), the operation shifts to the second operation. In the second operation, the second operation of the drive lever 11 is performed.
The cam portion 16 abuts on the second driven portion 18 and drives the same to move the strobe housing 3 around the support shaft 8 thereof in the direction of an arrow X7 shown in FIG. ). That is, the strobe housing 3 moves in the X4 direction shown in FIGS. In this state, the strobe housing 3 rotates in the X7 direction around the support shaft 8 near the contact point while the support section 7b and the fixing section 22 are in contact with each other. Then, the rear end face of one end 3b of the strobe housing 3 comes into contact with the fixing portion 23 on the inner wall surface on the upper surface side of the camera body (front cover 2). At the same time, the stopper 3 on the lower surface side of the substantially central portion of the strobe housing 3
c comes into contact with the fixing portion 24 on the inner wall surface on the upper surface side of the camera body (front cover 2). As a result, the strobe housing 3 becomes the second
, And the second operation is completed.

The strobe housing 3 in this state is urged by the urging force of the urging spring 10 (see FIG. 4) in the direction of the arrow X8 shown in FIG. On the other hand, the drive lever 11 is urged in the direction of arrow X9 (clockwise) in FIG. 7 by the urging force of the urging spring 14 (see FIG. 4). Here, since the urging force of the urging spring 14 is set to be stronger than the urging force of the urging spring 10, the strobe housing 3 is moved to the second projecting position. Is held.

When an external force is applied to the flash housing 3 in the direction of arrow X10 shown in FIG. 7 in this state, the flash housing 3 resists the urging force of the urging spring 10. The drive lever 11 rotates in the direction opposite to X9 (counterclockwise) against the urging force of the urging spring 14 to absorb the external force. In this state, the rotating shaft 13 is in the immobile state as described above, but since only the drive lever 11 can rotate in the counterclockwise direction, the external force is It does not affect the constituent members such as the lens 13 and the lens barrel connected thereto.

Next, when the strobe housing 3 is housed in the camera body, first, the lens barrier 2 is moved to X1 in FIG.
The power switch is turned off by sliding in the direction. Then, in conjunction with the turning-off operation of the power switch, the lens barrel of the photographing optical system 5 starts collapsing, and stores the lens barrel in the camera. At the time of the collapsing operation at this time, the projection 5a of the lens barrel moves in a direction along the optical axis, that is, in the camera. The protrusion 5a moves along the cam groove of the rotation shaft 13 so that the rotation
3 rotates counterclockwise (the direction opposite to the arrow X6 direction in FIG. 7) about the support shaft 12. And the rotating shaft 1
In conjunction with the rotation of the third lever 3, the drive lever 11 also starts to rotate in the same direction.

Further, the rotating shaft 13 and the driving lever 11
Is rotated counterclockwise, the flash housing 3 is moved in the direction opposite to the X4 direction in FIG. At this time, the second cam portion 16 of the drive lever 11 is connected to the arm 9 of the strobe housing 3.
Move along the contact surface of the second driven portion 18. Then, after the free end portion 3a of the flash housing 3 comes into contact with the fixed portion 20 on the camera body side in FIG. 6, the first cam portion 15 of the drive lever 11 is moved to the first driven portion 17 The first cam portion 15 moves along the contact surface.

When the retracting operation of the lens barrel is completed and the photographing optical system 5 stops the retracting operation,
Is completely stored in the camera body and is positioned at a predetermined storage position (the state of FIG. 1). At this time, the lens barrier 2 is in a fully closed state as shown in FIG. Thus, the storage operation of the strobe device is completed.

As described above, according to the above-described embodiment, the power is turned on in conjunction with the opening operation of the lens barrier 2, and in conjunction with a series of operations when the photographing optical system 5 is extended, the strobe device is operated. In a pop-up mechanism for popping up a strobe housing 3, which is a main component, from a non-irradiation position stored in the camera body to an irradiation-possible position protruding from the camera body, a first and second covers of the strobe housing 3 are provided. First and second cam units 1 for driving the driving units 17 and 18
By forming the flash units 5 and 16, the flash unit 3 is configured to perform the step-by-step projection operation by the first projection operation and the second projection operation. Can be moved, and the amount of movement of the strobe housing 3 at each stage can be reduced, but the amount of movement of the strobe device itself can be made larger. Therefore, reducing the amount of movement in each stage can contribute to downsizing of a camera to which the movement is applied.

Further, since a large amount of movement of the strobe device itself can be secured and the photographing optical system 5 on the camera body side and the irradiation position of the strobe device can be arranged separately, so-called so-called photographing, which occurs during photographing, can be performed. Prevent red-eye effect, etc.
It is easy to obtain better photography results.
