DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera with a built-in flash device, and more particularly to a camera in which a flash light emitting portion can be moved between a storage position and a light emitting position, and a light emission irradiation angle can be switched.

[0002]

2. Description of the Related Art Conventionally, various cameras with a built-in flash device have been proposed or commercialized. In particular, in recent years, as cameras have become smaller and the zoom ratio of a photographic lens has increased, The distance between the photographic lens optical axis and the flash optical axis becomes smaller, and the distance between the subject (person) and the camera, that is, the so-called photographic optical axis, tends to increase. As a result, the so-called red-eye phenomenon, in which flash light is incident on the pupil of the subject (person) and reflected on the retina, is likely to occur,
Suppressing this red-eye phenomenon must be considered important in commercializing cameras.

As a means for suppressing the red-eye effect, a camera having a means for contracting a pupil of a subject (person) by causing a flash device to emit preliminary light immediately before photographing or by emitting a light source (lamp) other than the flash device. Have been proposed. As another means, a so-called pop-up flash device for moving the flash light emitting unit away from the photographing lens optical axis when using the flash device is also well known, and this device has a flash device housed in the camera except during shooting. Since it is easy to carry and has a great effect of reducing the red-eye effect, various proposals have been made since ancient times.

On the other hand, many cameras have been commercialized that make it possible to efficiently use the light energy of a flash tube by changing the irradiation angle of flash light emission according to the focal length of a photographing lens.

[0005]

By the way, usually, the flash irradiation angle only needs to cover the range of the angle of view of the photographing lens.
In the case of a camera whose flash irradiation angle is not switchable, the irradiation angle is set so as to cover the angle of view at the widest focal length among the changeable focal lengths of the photographing lens. Even if it is changed to the tele side, the flash irradiation angle remains the irradiation angle covering the wide-angle of view. In general, the flash guide number is always constant irrespective of the focal length of the photographing lens, and is generally determined by the photographable distance on the tele side where the F number of the photographing lens is large. For this reason, since light is emitted at an irradiation angle that covers the shooting angle of view on the wide side even on the telephoto side, the light energy emitted outside the shooting angle of view is wasted without being used at all.

As described above, in the case of a camera in which the focal length can be changed and the flash irradiation angle is not variable, the flash device needs to satisfy the wide-angle irradiation angle and the telephoto shooting range. The zoom ratio of the shooting lens increases,
If the F-number of the taking lens increases, the flash guide number must be increased accordingly. However, to increase the guide number requires a correspondingly large amount of electric energy, so that components such as a charging capacitor and a flash tube are increased in size, resulting in an increase in the size of the camera. In addition, when the size of the charging capacitor is increased, the charging time is prolonged. When performing continuous shooting, there is a problem that the waiting time for charging is long and the quick shooting performance is lacking.

In order to solve such a problem, as described above, the flash irradiation angle is changed according to the focal length of the photographing lens, so that light energy is efficiently used without wasting even in photographing on the telephoto side. Various products have been proposed which prevent the size of the battery from increasing and do not increase the waiting time for charging. A flash device that combines such a pop-up type flash device and a flash device capable of switching the irradiation angle has also been proposed. Normally, in the case of a fixed flash device that does not pop up, the irradiation angle is switched between the camera body and the flash light emitting unit via a lever, gear, belt, etc. Fold these interlocking members with the main body side during the storage operation of the device,
Alternatively, it is necessary to cancel the interlock, and there has been a problem that the mechanism is complicated and the size is increased.

[0008] Japanese Patent Application Laid-Open No. 3-38627 discloses that
In a camera having a flash light emitting portion movable between a protruding position and a storage position, a member for regulating a position of a flash tube and a lever for transmitting position information are folded when the flash device is stored, and a means for interrupting information transmission with the main body side. Has been proposed. However, in this conventional example, a member for regulating the position of the flash tube and a lever for transmitting position information are provided, and a spring is applied between these two members, so that the number of parts is large and the mechanism is complicated. Further, in this conventional example, the flash device is always spring-biased in the pop-up direction, is held by the lock mechanism at the storage position, the pop-up operation is performed by releasing the lock mechanism, and the storage operation is performed by the flash light emitting unit. In this case, the flash light emitting portion remains protruding even when the shooting is terminated and the camera power is turned off, so that the operability must be pushed by hand, and the operability is not good. .

The present invention eliminates the drawbacks of the prior art described above, and provides a camera in which the flash light emitting portion is movable between a storage position and a projecting position (light emitting position) and the emission angle of light can be switched. An object of the present invention is to provide a camera with a built-in flash device that can automatically move to a position on the camera side and switch the light emission angle without increasing the size by a simplified mechanism with a small number of components.

Reference numeral 18 denotes a connecting rod, one end of which is fitted into the shaft 14c of the holder 14 and the other end of which is formed with a long hole 18a. The long hole 18a prevents the end of the crank portion 17c of the drive spring 17 from coming off. It is connected in the state that it was.

In this embodiment having the above structure, when the flash light emitting unit 8 shown in FIG. 3 is stored, the one end 17a of the drive spring 17 is moved away from the pin 16c of the drive lever 16, and the other end 17b is driven. Since the flash light emitting unit 8 is at the position pressed by the lever 16, the one end 17a of the flash light emitting unit unit 8 is stably spring-biased in the storing direction by abutting the pin 9c of the flash light emitting unit case 9. Become. At this time, a load is applied to the drive lever 16 in the counterclockwise direction by the other end 17b of the drive spring 17, and a load is applied to the drive cam 5 via the slide plate 7 and the lever 6 so as to rotate in the counterclockwise direction. Since the row 4 includes a gear connection by the worm gear 4a and the worm 4b, the rotation is prevented and the motor 3 does not rotate.

Therefore, in this embodiment, FIGS.
In the state shown in (1), the power is off, and the taking lens barrel is also in the retracted state. When the power switch of the camera is turned on from this state, the motor 3 is energized, the rotation is transmitted to the drive ring 2 via the reduction gear train 4, and the drive ring 2 starts rotating counterclockwise. Then, as described above, the photographing lens barrel starts to extend in conjunction with the rotation direction of the drive ring 2 due to the well-known cam groove and cam follower configuration, and in conjunction with that, the drive cam 5 also rotates counterclockwise. Start.

When the driving cam 5 rotates counterclockwise, the cam follower shaft 6b of the L-shaped lever 6, which has fallen into the concave portion 5a of the cam surface, is lifted along the cam surface. It rotates clockwise, and the slide plate 7 is pushed down by the shaft 6c at the other end. Further, since the pin 16b of the drive lever 16 is engaged with the notch 7c of the slide plate 7, the drive lever 16 rotates counterclockwise in conjunction with the downward movement of the slide plate 7.

At this time, both ends 17 of the drive spring 17
a and 17b are the pins 16 of the drive lever 16 as described above.
Since this is the state where c is sandwiched, it rotates integrally with the drive lever 16. The rotation of the drive spring 17 releases the flash light emitting unit 8 in the storage direction, and furthermore, the pin 9a of the flash light emitting unit case 9 moves the drive spring 1
7 starts to rotate clockwise by being pushed by one end 17b. Further, when the motor 3 is kept energized, the flash light emitting unit 8 comes into contact with a stopper of the camera body 1 (not shown) and is pressed by one end 17b to the light emitting position. In this case, since the other end 17a is pushed by the pin 16c until the one end 17b is separated from the pin 16c of the drive lever 16, the flash light emitting unit 8 is stably pressed to the light emitting position by the one end 17b. Also,
At this time, the drive lever 16 is connected to one end 1 of the drive spring 17.
7a, the slide plate 7 is pulled upward, and the L-shaped lever 6 is urged counterclockwise, but the cam follower shaft 6b of the L-shaped lever 6 is driven by the drive cam 5 , The rotational force is not transmitted to the drive cam 5, and the position of each of these components is stably regulated. Next, when the position detecting means of the photographing lens barrel detects the wide position, the energization of the motor 3 is terminated, and the photographing is enabled at the wide position in FIG.

FIG. 5 shows the state of the flash tube 10 at this time.
The end 18 of the long hole 18a of the connecting rod 18 as shown in FIG.
a 'and the crank part 1 of one end 17a of the drive spring 17
Since the gap is provided between the flash tube 7c and the flash tube 10, the flash tube 10 is kept urged to the irradiation surface side by the spring 15 together with the holder 14, and the irradiation angle is wide.

Next, the zoom operation will be described. In this state, when the user operates a zoom button (not shown) provided on the camera body 1 in the telephoto direction, the motor 3 is energized again, interlocked with the extension of the lens barrel, and the drive cam 5 is turned counterclockwise as described above. Rotate in the direction. The cam surface 5b of the drive cam 5 against which the cam follower shaft 6b of the L-shaped lever 6 is in contact
Is an arc centered on the rotation axis of the drive cam 5,
The lever 6 does not rotate, and the flash unit 8
The zoom operation is performed while maintaining the same state until that time.

When the zoom operation is continued and the focal length of the photographing lens barrel is near the middle, the L-shaped lever 6 rotates clockwise until the cam follower shaft 6b rides on the cam surface 5c of the driving cam 5. The drive lever 16 also rotates through the slide plate 7 in conjunction with the drive lever 16. This drive lever 1
The one end 17a of the drive spring 17 is further rotated by the rotation of 6, but the flash light emitting unit case 9 does not rotate any more because it is in contact with the stopper, and the other end 17b of the drive spring 17 is connected to the stopper pin 9a. It remains in contact.

Then, one end 17a of the drive spring 17
Of the connecting rod 18
And the connecting rod 18 is to be moved in the forward direction of the camera. The other end of the connecting rod 18 is held by the shaft 14c of the holder 14, and the spring force of the drive spring 17 is set to be sufficiently larger than the urging force of the spring 15, so that the holder 14
The flash tube 10 rotates clockwise around the 4a against the urging force of the spring 15, and the flash tube 10 comes into contact with the reflection surface of the reflection shade 11 to function as a stopper, thereby stably regulating the position. When the flash tube 10 is brought into close contact with the reflection surface of the reflection shade 11, the irradiation light is condensed, and the irradiation angle is set according to the angle of view of the focal length of the photographing lens.

At this time, as shown in FIG. 8, the position of the rotating shaft 14a of the holder 14 is perpendicular to the flash axis, and the midpoint between the flash tube position A on the wide side and the flash tube position B on the tele side is set. (The axis passing through the vertex of an isosceles triangle whose base is the line segment connecting AB and parallel to the flash tube 10 is the rotation axis 14)
a), the position of the flash tube 10 has a circular arc of movement, but no deviation from the flash optical axis occurs at each position.

When the zoom operation is continued, the taking lens barrel moves toward the telephoto end. However, since the cam surface 5c of the drive cam 5 is formed by an arc centered on the rotation axis, the L-shaped lever is formed. The components beyond 6 keep their positional relationship.

The operation in the wide direction may be the reverse of the operation in the tele direction, and when the motor 3 is energized in the counterclockwise direction, the drive ring 2 And the taking lens barrel moves in the wide direction. In conjunction therewith, the drive cam 5 rotates counterclockwise, and the taking lens barrel drops one step to the cam surface 5b of the L-shaped lever 6 near the middle, so that the slide plate 7 drives the drive spring 17 via the drive lever 16. Thereby, the upward movement becomes possible, and the one end 17a can also be rotated clockwise. When the one end 17a of the drive spring 17 rotates clockwise, the holder 14 that has been pulled by the connecting rod 18 is released from the clockwise rotation bias, and is rotated counterclockwise by the spring 15, so that the holder 14 is rotated. Convex part 1
4b comes into contact with the stopper surface 9a of the flash light emitting unit case 9, that is, the wide-side position.

When the camera power is turned off, the motor 3 is further energized, and the taking lens barrel is retracted. After passing through the wide end, the cam follower shaft 6b of the L-shaped lever 6 is pressed against the cam surface 5b of the drive cam 5, so that it falls into the concave portion 5a according to the clockwise rotation, and the slide plate 7 moves upward. Then, the drive lever 16 is released from the clockwise rotational bias by the other end 17b of the drive spring 17.

Further, the driving cam 5 rotates, and the concave portion 5
When the L-shaped lever 6 rotates counterclockwise due to a,
The flash light emitting unit 8 rotates in the storage direction in conjunction with the slide plate 7 and the drive lever 16, and the rotation is restricted at a position where it contacts a stopper (not shown) of the camera body 1.

Further, the drive cam 5 rotates, and the L-shaped lever 6, the slide plate 7 and the drive lever 16 move in conjunction therewith and move away from the pin 16c of the drive lever 16 at one end 17a of the drive spring 17. Although the operation is continued up to the position, the flash light emitting unit 8 is brought into contact with the stopper to restrict the rotation operation.
By the spring force of (1), it can be stably pressed in the storage direction. Next, the position detecting means of the taking lens barrel detects the retracted position, the power supply to the motor 3 is cut off, and the power-off operation of the camera ends.

As described above, the basic operation of the flash device in the camera according to the present embodiment is as follows. The flash light emitting unit 8 always projects in the photographing enabled state and is in the light emitting state. This also provides a camera with good operability that does not impair the quick shooting performance. In addition, since the flash light emitting unit 8 always projects, the projecting state,
Alternatively, even if some external force is applied to the flash light emitting unit 8 during the protruding operation and is pressed in the storage direction, the other end 17b of the drive spring 17 is rotated by the pin 9c of the flash light emitting case 9 as shown in FIG. , Only when the spring is charged, the drive lever 16, the slide plate 7 and L
No movement is transmitted to the shaped lever 6 and their associated components are not destroyed.

Conversely, even if some external force is applied to the flash light emitting unit 8 during the storing operation so as to prevent the operation, the one end 17a of the drive spring 17 is rotated by the pin 9c of the flash light emitting unit case 9. However, the operation is not transmitted to the drive lever 16, the slide plate 7, and the L-shaped lever 6 only by charging the spring, and the related components are not destroyed.

In any case, even if such an abnormal operation is applied, the shaft 14c of the holder 14 is located substantially coaxially with the shafts 1a and 1b, which are the rotation axes of the flash light emitting unit 8. The connecting rod 18 is such that one end 17a of the driving spring 17 moves along the elongated hole 18a and is only rotated about the shaft 14c.
No excessive load is applied to 4 and it is not destroyed.
