Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a strobe device,
More specifically, the present invention relates to a pop-up mechanism for moving a strobe device provided on a camera body between a non-irradiation position (storage position) and an irradiation-possible position (projection position).

[0002]

2. Description of the Related Art Conventionally, a small camera or the like using a roll film having a width of 35 mm generally has a built-in strobe device for irradiating an auxiliary light for taking a picture in a camera body. It is widespread.

In such a camera or the like, 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 so-called pop-up mechanism that moves the strobe device between a non-irradiation position (storage position) for storing the strobe device inside the camera body and an irradiation-possible position (projection position) for protruding outside the camera body in conjunction with an on / off operation. There are various proposals and practical applications.

For example, a pop-up mechanism of a strobe device disclosed in Japanese Patent Application Laid-Open No. 6-242497 moves a strobe device to a protruding position and a storage position with respect to a camera body in synchronization with operations of starting and stopping photographing. It is intended to be. According to the means disclosed in this publication, a strobe housing provided with one end rotatably supported by the camera body is biased in a projecting direction by a single biasing spring. ing.

The applicant of the present application has previously filed Japanese Patent Application No. 9-2856.
No. 20, the pop-up mechanism of the strobe device configured to suppress the amount of movement of the drive member itself for moving the strobe device and to secure a large amount of protrusion of the strobe device despite the smaller driving force. Means are disclosed.

In this pop-up mechanism, a strobe housing whose one end is rotatably supported with respect to the camera body is connected to a single drive lever via a drive lever whose one end is rotatably fixed. The urging force of the urging spring urges the camera body in the direction of being housed inside the camera body, and interlocks with the operation when the lens barrel holding the photographing optical system moves to the retracted position and the photographing preparation position. The drive lever is configured to rotate in a predetermined direction.

As a result, the drive lever pivots in a predetermined direction as the lens barrel and the like move between the retracted position and the photographing preparation position due to the power-on operation or the power-off operation. A drive lever projects the strobe housing toward the outside of the camera body against the urging force of the urging spring to move the strobe housing to an irradiation-possible position.

[0008]

However, according to the means disclosed in the above-mentioned Japanese Patent Application Laid-Open No. Hei 6-242497 and the means proposed by the present applicant in Japanese Patent Application No. 9-285620, a strobe device is disclosed. Is configured to be moved by a single urging spring, so that a large amount of urging spring is required, and considering the amount of force of this urging spring, each component such as You need to set the intensity. Therefore, there is a problem that the size of each component constituting the mechanism for popping up the strobe device also increases the size of the camera itself in which the pop-up mechanism is disposed inside the main body.

When the strobe device is moved in the projecting direction by a single urging spring, the strobe device can be moved from the storage position of the strobe device to the outside of the camera body to some extent from the storage position of the strobe device. Comparing the required amount of force and the amount of force required from this state until the strobe device completes the movement to the protruding position, the former requires a large amount of force, whereas the latter requires a large amount of force. The operation is completed without requiring a large amount of force. Therefore, the setting of the force amount of the biasing spring must be large in consideration of the former, but since the force amount cannot be efficiently distributed during the pop-up operation, it is necessary to perform a useless operation. There is a problem that it becomes.

Further, according to the means proposed in Japanese Patent Application No. 9-285620, each member such as a drive lever constituting the pop-up mechanism needs to be provided in a space on the lower side of the strobe housing due to its structure. Therefore, it can be said that this means lacks the degree of freedom in the arrangement of members. As a result, when the same means is used, the size of the entire flash device including the pop-up mechanism in the vertical (height) direction becomes large, so that the camera itself containing the same also tends to become large. There is a problem that there is.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object the pop-up for moving a strobe device between a non-irradiation position (storage position) and an irradiation-possible position (projection position). In the mechanism, there is provided a strobe device having a pop-up mechanism in which the space occupied by the entire strobe device including the pop-up mechanism inside the camera body is reduced, and the strobe device can be popped up by a smaller driving force. is there.

8, the first lifting lever 13 attempts to rotate with respect to the second lifting lever 14, but the stopper 13c of the first lifting lever 13 contacts the support arm 14b of the second lifting lever 14. In contact, its rotation is prevented. Therefore, the third spring 13 integrates the first jumping lever 13 and the second jumping lever 14.

The driving plate 21 is integrally provided with a claw 21a serving as a driving member. This claw portion 21a
When the driving plate 21 rotates in the same direction (the direction of the arrow X7 in FIG. 3) in conjunction with the extension operation of the lens barrel or the like, the claw portion 14a, which is the driven portion of the second flip-up lever 14, It is configured to engage with.

As a result, the driving plate 21 applies a driving force when the lens barrel or the like of the photographing optical system 5 is extended through the claw 21a of the driving plate 21 and the claw 14a of the second lifting lever 14. The signal is transmitted to one jump lever 13. As a result, the first lifting lever 13 moves the cam pin 13b and the cam portion 12
The strobe housing 3 is rotated toward the projecting position via the first drive lever 12 by the action of a.

The amount of force (urging force) of the third spring 18 that integrates the first jumping lever 13 and the second jumping lever 14 is determined by the urging force of the first spring 19 and the second spring 20.
Is set so as to be an urging force having a strength greater than the resultant force (urging force in the storage direction).

The operation of the electronic flash device of this embodiment having the above-described configuration will be described below with reference to FIGS.
4 and 5 are enlarged views of a main part of a camera having the present strobe device. FIG. 4 shows a state where the present strobe device is in a storage position (corresponding to the state of FIG. 1). )
FIG. 5 shows a state (corresponding to the state shown in FIG. 2) in which the flash device is in the protruding position. 4 and 5, only the strobe device and its pop-up mechanism are shown, and other components disposed inside the camera body are omitted to avoid complication of the drawings.

When the camera of this embodiment is not used, the lens barrier 2 is closed as shown in FIG. 1, and the strobe housing 3 of the strobe device in this state is shown in FIGS. As shown in the figure, the camera is housed in the housing position in the camera body.

That is, in this state, the support lever 11 is urged by the urging force of the first spring 19 wound around the first shaft member 17 in the direction in which the strobe housing 3 is in the storage position. . The flash housing 3 is urged toward the support lever 11 by the urging force of the second spring 20 wound around the second shaft member 16. The contact portion 3g on the lower surface side of the strobe housing 3 is in contact with the abutted surface 8a of the fixing member 8 inside the camera body, whereby the strobe housing 3 is stably held at a predetermined storage position. Is positioned.

At this time, the cam pin 13b of the first lifting lever 13 is located at the cam portion 12a of the first drive lever 12, and the first drive lever 12 is further attached to the bottom of the strobe housing 3. The rotation is restricted by the driven part 3f. Therefore, the storage state of the flash housing 3 is maintained.

When the user of the camera puts the camera into a shooting preparation state for taking a picture or the like with the strobe housing 3 in the storage position as described above, 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.

When the driving plate 21 rotates in the direction of the arrow X7 in FIG.
Is engaged with the claw portion 14a of the second jumping lever 14, and the second jumping lever 14 is turned around the third shaft member 15 in FIG.
Is turned counterclockwise. Here, since the third spring 18 is interposed in the second lifting lever 14, the first lifting lever 13 also rotates in the same direction. When the first jumping lever 13 rotates counterclockwise about the third shaft member 15, the cam pin 13b of the lever 13 moves to the cam portion 12a.
The first drive lever 12 is pushed upward while sliding along. Therefore, the lever 12 rotates clockwise in FIG. 4 around the first shaft member 17.

Thus, the strobe housing 3 moves in the direction protruding outside the camera body. In this state, the flash housing 3 is urged in the direction of the support lever 11 by the urging force of the second spring 20, and the support lever 11 is urged by the urging force of the first spring 19. The housing 3 is urged in the storage direction.

Therefore, as described above, the third spring 18
When the flash housing 3 is pushed upward through the first lifting lever 13 and the first drive lever 12 by the interposition of the urging force, the flash housing 3 is connected to the support lever 11 at the second shaft member 16. Therefore, the lever 11 is pushed upward together with the lever 11.

At this time, the support lever 11 and the flash housing 3
Between the support lever 11 and the fixing member 8 of the camera body, while urging the strobe housing 3 toward the lever 11 side. Between them, the urging force of the first spring 19 acts, thereby urging the support lever 11 in the counterclockwise direction (the storage direction of the flash housing 3).

However, the aforementioned biasing force of the third spring 18 is:
The strobe housing 3 is configured such that the biasing force of the first spring 19 and the biasing force of the second spring 20 are greater than the resultant force (the biasing force in the storage direction).
Rotates counterclockwise (projecting direction) about the second shaft member 16 against the biasing force of the second spring 20, and the support lever 11 resists the biasing force of the first spring 19. To rotate clockwise around the first shaft member 17.

When the locking member 3e is locked to the locked portion 7, the strobe housing 3 is positioned at a predetermined projecting position as shown in FIG. In this state, the relationship between the urging forces of the first spring 19 and the second spring 20 and the urging force of the third spring 18 is as described above, so that the strobe housing 3 projects in the state shown in FIG. Will be held in position.

In this state, when an external force or the like is applied to the strobe housing 3 from, for example, the direction of arrow X10 in FIG.
8 in the direction of the storage position against the urging force. That is, the external force applied to the strobe housing 3 from the direction of the arrow X <b> 10 is transmitted to the first lifting lever 13 via the first driving lever 12. This first lifting lever 13 is
Although it rotates clockwise about the shaft member 15, the external force is absorbed by the third spring 18 and is configured not to be transmitted to the second up lever 14.

That is, even when an external force is applied to the strobe housing 3, the second lifting lever 14 can continue to maintain the state shown in FIG. Therefore, the external force applied to the strobe housing 3 does not affect the engagement state between the claw portion 14a of the second lifting lever 14 and the claw portion 21a of the drive plate 21 or these constituent members.

Next, in order to move the strobe housing 3 from the protruding position shown in FIG. 5 to a storage state (the state shown in FIG. 4) in which the strobe housing 3 is stored inside the camera body, First, the lens barrier 2 is slid in the direction of arrow X1 in FIG. As a result, the power switch is turned off. 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. With this collapsing operation, the drive plate 21 rotates in the direction of arrow X8 in FIG. Thereby, the first lifting lever 13
Rotates clockwise about the third shaft member 15 by the urging force of the first spring 19. This first lifting lever 1
With the rotation of 3, the second lifting lever 14 also starts to rotate in the same direction.

At this time, the strobe housing 3 starts to move downward for the following reason. When the strobe housing 3 moves downward, the cam portion 12a of the first drive lever 12 pushes the cam pin 13b downward. Strobe case 3
Is rotated clockwise about the second shaft member 16 by the urging force of the second spring 20, and the support lever 11
Rotates counterclockwise around the first shaft member 17 by the urging force of the first spring 19. As a result, the strobe housing 3 starts moving in the storage direction, and the contact portion 3g comes into contact with the contact surface 8a of the fixing member 8, whereby positioning at the predetermined storage position is performed.

As described above, according to the above-described embodiment, the two biasing springs (the first spring 19 and the second spring 20) for biasing the strobe housing 3 in the direction of being housed inside the camera body. Are provided near both ends of a support lever 11 for rotatably instructing the flash housing 3, and a first drive lever 12 and a second drive lever (second drive lever) for projecting the flash housing 3 out of the camera body. By providing a jumping lever 14 and a first jumping lever 13), the driving force when the shooting optical system 5 is extended is transmitted to the first driving lever 12 through the second driving lever. The strobe housing 3 is configured to protrude outside the camera body.

Therefore, compared to the conventional pop-up mechanism in which the strobe device is protruded toward the outside of the camera body by a single urging means, the load applied to each component is dispersed, and the driving efficiency is improved. Power transmission can be realized.

The second receiving the driving force of the photographing optical system 5
Since the degree of freedom in the arrangement of the drive lever is increased, the vertical (height) dimension of the strobe device including the pop-up mechanism can be reduced. Therefore, the present invention contributes to downsizing of the strobe device and the downsizing of the camera itself using the same.

By reducing the size of each component of the pop-up mechanism of the strobe device and transmitting the driving force more efficiently, the space occupied by the pop-up mechanism inside the camera body can be reduced. In addition, the strobe device can be moved with a smaller driving force. Therefore, a strobe device that contributes to downsizing of the camera itself can be provided.

Incidentally, in the above-described embodiment,
Support lever 11 for rotatably supporting strobe housing 3
And the first drive lever 12 for moving the strobe housing 3 to a predetermined projecting position is configured to be coaxially supported by the first shaft member 17. However, the present invention is not limited to such a configuration. A configuration as shown in FIG. 6 may be used.

FIG. 6 shows a modification of the above embodiment.
FIG. 2 is an enlarged view of a main part showing only a strobe device provided in the camera and constituent members near a pop-up mechanism thereof. Note that the basic configuration of this modification is substantially the same as that of the above-described embodiment, and the first drive lever 1
The only difference is the position where the shaft 2 is supported.

That is, in this modified example, as shown in FIG. 6, the support lever 11 is pivotally supported by a first shaft member 17 on a fixed portion (not shown) of the camera body, similarly to the above-described embodiment. The first drive lever 12 is supported by a fourth shaft member 17B with respect to a fixed portion (not shown) of the camera body.
