Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly, to an improvement of a camera having a pop-up type flash light emitting unit.

[0002]

2. Description of the Related Art A compact camera having a built-in strobe device has been widely used so that night photography or backlight photography can be easily performed. It is known that when portrait photography is performed using such a camera with a built-in strobe, a so-called red-eye phenomenon occurs. This red-eye phenomenon is a phenomenon caused by emitting red light when the retina of the eye reflects strobe light, and the optical axis of subject light incident on the taking lens,
Appears remarkably when the optical axis of the strobe light is too close. For this reason, it is preferable that the strobe light emitting unit is arranged at a position as far as possible from the optical axis of the taking lens.

In order to reduce the red-eye effect, there is known a camera provided with a pop-up strobe device.
This camera has a storage position stored in the camera body,
The strobe light-emitting part can be moved freely between the exposure position exposed from the camera body and the optical axis of the strobe light is separated from the optical axis of the subject light only during flash shooting, thereby preventing the occurrence of the red-eye phenomenon. is there. In the conventional camera, as a drive source of the mechanism that pops up the strobe light emitting unit,
The rotation of the gear branched from the middle of the gear train that drives the lens barrel is used. Also, Japanese Patent Application Laid-Open No. 7-1992
As described in Japanese Patent Publication No. 95, there has been invented a camera that pops up a strobe light-emitting portion by using the movement of a finder lens that operates in conjunction with the retracting and extending operations of a lens barrel.

[0004] The above-mentioned conventional camera incorporates springs for urging the strobe light emitting portion to the storage position and the exposure position, respectively. These springs are provided with a spring when the strobe light-emitting part in the exposure position is forcibly moved to the storage position by hand or the strobe light-emitting part in the storage position is forcibly moved to the exposure position. Return to the original position by the power.

A camera provided with a pop-up type strobe device is provided with a detection switch for detecting that the strobe light-emitting portion is in an exposed position, and the strobe light is detected only when this detection switch detects the strobe light-emitting portion. Some of them allow light emission.

[0006]

A camera provided with a pop-up strobe light emitting unit requires an operation member for moving the strobe light emitting unit between an exposure position and a storage position. However, it is very troublesome to move the flash unit every time a picture is taken, so that the power of the camera is turned off while the flash unit is exposed, and the flash unit protruding from the camera body may be turned off. It could be damaged. In addition, the movement of the strobe light emitting unit using the driving of the gear increases the number of parts and complicates the mechanism, causing problems such as deterioration in suitability for assembly and failure.

Further, in the camera described in Japanese Patent Application Laid-Open No. 7-199295, it is necessary to balance the urging forces of two types of springs for urging the strobe light-emitting portion between the exposure position and the storage position, so that a high component accuracy is obtained. Is required, making assembly very difficult. Also, since the operation of the lens barrel is transmitted to the strobe light emitting unit via the finder lens,
There is a problem that the occurrence rate of failures and malfunctions increases due to the increase of related parts, and the adequacy of assembly also deteriorates.

Further, in a camera which permits strobe light only when the strobe light emitting unit is at the exposure position, if the detection switch has a conduction failure, the strobe light is not emitted and the light quantity becomes insufficient, so that a basic camera as a built-in strobe camera is used. There was a problem that the photographing function could not be performed.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a camera having a low-cost, high-reliability, pop-up strobe light emitting section.

[0010]

In order to solve the above problems, a camera according to the present invention moves a strobe light emitting unit between a storage position and an exposure position in conjunction with the retracting and extending operations of a lens barrel. In addition to providing an interlocking mechanism to move between the two, attach the interlocking mechanism to the main body base, attach the strobe light emitting unit to the front cover, and connect the strobe light emitting unit and the interlocking mechanism when attaching the front cover to the main body base This improves the suitability for assembly.

Further, an exposing spring for urging the strobe light emitting portion toward the exposing position is provided in the interlocking mechanism, and the strobe light emitting portion is moved to the storage position against the urging of the exposing spring when the lens barrel is retracted. The strobe light-emitting portion is moved to the exposure position by the urging force of the exposure spring when the lens barrel is extended. Further, a stowage spring is provided in the strobe light emitting portion for returning the strobe light emitting portion to the stowed position when the strobe light emitting portion in the stowed position is forcibly pulled and moved to the exposed position by hand. .

Further, a detection switch for detecting that the strobe light emitting portion is near the storage position is provided, and the strobe light emission is inhibited by this detection switch. Further, the strobe light emission is prohibited when the detection switch is conducting.

2 is attached.

The base member 28 is provided in the film winding chamber 2.
The base plate 34 is screwed to an upper surface of the base plate 0, and a holding plate 35 that stands upright on one edge of the base plate 34 and holds the interlocking member 29 is provided. On the holding plate 35, rails 36a and 36b slidingly contacting the interlocking member 29, and holding projections 37a and 37a protruding from the rails 36a and 36b are provided.
37b are integrally formed. Rails 36a, 3
6b reduces the sliding contact area between the base member 28 and the interlocking member 29 so that the interlocking member 29 can slide smoothly. The holding projections 37a, 37b are formed in a key shape, and slits 38a, 38 formed in the interlocking member 29 are formed.

The slits 38a and 38b are shaped so that the holding projections 37a and 37b can be inserted when the interlocking member 29 is attached to the base plate 28.

The spring-hanging projections 40, 4 on which the coil spring 30 is hooked are provided between the edge of the holding plate 35 on the front side of the camera body 3 and the edge of the interlocking member 29 on the back side of the camera body 3.
1 are formed respectively. Thereby, the interlocking member 2
9 is urged toward the front side of the camera body 3. In order to reduce the size of the interlocking mechanism 27, the interlocking member 29 is formed with a recess 42 in which the coil spring 30 is housed.

At the lower part of the interlocking member 29, an engaging pin 45 inserted into a slit 44 formed in the fixed cylinder 18 of the main body base 4 is integrally formed. This engagement pin 45
In the fixed cylinder 18, it comes into contact with the back surface of the engagement piece 46 formed on the outer peripheral portion of the straight guide plate 22. Straight guide plate 2
When the lens barrel 9 is collapsed in the camera body 3, the engagement pin 45 presses the engagement pin 45 toward the rear side of the camera body 3. Thereby, the interlocking member 29 is slid to the rear side of the camera body 3 against the bias of the coil spring 30, as shown in FIG. When the lens barrel 9 is extended from the camera body 3, the pressing of the engaging pin 45 by the engaging piece 46 of the rectilinear guide plate 22 is released. Thereby, the interlocking member 29 is slid toward the front side of the camera body 3 by the bias of the coil spring 30, as shown in FIG.

The slit 44 has a minimum size necessary for the movement of the engaging pin 45, and the seat 29a of the interlocking member 29 covers the slit 44 over the entire moving range of the interlocking member 29. Since it functions as a member, external light, strobe light, and the like pass through the slit 44 through the fixed cylinder 18.
It does not penetrate into the photo film and adversely affect it.

On the circuit board 32 on which the strobe circuit is formed, a strobe light emission inhibition switch 48 as a detection switch is provided.
Are mounted so as to protrude downward. The strobe light emission prohibition switch 48 is formed of a pair of elastic metal contact pieces 48a and 48b.
This is an open (NO) type switch, which is turned on (conducted) when the metal contact pieces 48a and 48b are in contact with each other to open the strobe circuit, and the strobe light emitting section 1
4 strobe flash is prohibited.

On the surface of the interlocking member 29 on the side facing the holding plate 35, a switching projection 49 for switching on / off the strobe light emission inhibition switch 48 is integrally formed. The switching projection 49 is inserted into a slit 50 formed in the holding plate 35 and protrudes above the base plate 34.
The switching projection 49 presses one of the metal contact pieces 48a when the interlocking member 29 is slid to the rear side of the camera body 3 and contacts the other metal contact piece 48b to turn on the strobe light emission inhibition switch 48. . One metal piece 48a
In order to secure the pressing by the switching projection 49, a pressed piece 52 wider than the metal contact piece 48a is attached to the switch.

As described above, when the strobe light emission section 14 is in the storage position, the strobe light emission inhibition switch 48 is turned on to inhibit the strobe light emission. Even if it disappears, there is no problem that the flash is not emitted at the time of photographing that requires the flash.

The strobe light emitting section 14 is rotatably mounted on a light emitting section chamber 16 formed integrally with the front cover 5 via a rotating shaft 54. An opening 55 for connecting the interlocking mechanism 27 attached to the main body base 4 to the strobe light emitting unit 14 is formed on the bottom surface in the light emitting unit chamber 16. A box-shaped shielding portion 56 that covers the strobe lens 15 when the strobe light emitting portion 14 is turned to the storage position is provided on the bottom surface on the front side of the camera body 3 in the light emitting portion chamber 16.
Are formed. The shielding unit 56 is activated by the failure of the strobe light emission prohibition switch 48 or the like.
Even if the strobe light is emitted while the camera is in the storage position, the strobe light is prevented from entering the camera body 3.

As shown in an exploded view in FIG. 8, the strobe light emitting section 14 includes a light emitting section main body 60 in which a discharge tube 58 and a reflector 59 are incorporated, and an exterior cover 61 to which the light emitting section main body 60 is attached. A rotating shaft 5 that is inserted into bearing holes 62 and 63 formed in the light emitting unit chamber 16 and the outer cover 61 and rotatably supports the outer cover 61.
4, an interlocking lever 65 rotatably attached to the rotating shaft 54, and a torsion spring 66 serving as a storage spring.

The light emitting section main body 60 is integrally formed of plastic having a light shielding property, and a reflector 59 and a discharge tube 58 are incorporated through an opening 68 provided on the front side. Closed with.
The light emitting unit main body 60 is screwed inside the outer case 61. The conventional light emitting unit main body 60 includes a holding member that holds the reflector 59 and the discharge tube 58, and a light-shielding cover that covers above and below the holding member. Since the main body 60 is formed integrally, it is possible to reduce the number of parts, reduce cost, and improve the suitability for assembly.

The interlocking lever 65 is connected to a connecting pin 7 which engages with a forked connecting portion 70 formed on the upper portion of the interlocking member 29.
1 and a spring hook 7 on which one end of the torsion spring 66 is hooked
2 and a contact piece 73 formed on the inner wall surface of the outer case 61
And a contact projection 74 that is in contact with is formed integrally. As shown in FIG. 6, the other end of the torsion spring 66 is
1, and the interlocking lever 65 is urged clockwise in the figure by a torsion spring 66. The interlocking lever 65 urged by the torsion spring 66 is in a state where the contact protrusion 74 is always in contact with the contact piece 73 of the outer case 61.

Since the connecting pin 71 is engaged with the connecting portion 70 of the interlocking member 29, the interlocking member 29 is pressed by the rectilinear guide plate 22 as shown in FIG. When it is slid to the side, the outer case 61 is rotated via the torsion spring 66 to move the strobe light emitting unit 14 to the storage position. As shown in FIG. 7, when the interlocking member 29 is slid to the front side of the camera body 3, the interlocking lever 65 presses the contact piece 73 by the contact protrusion 74, and To the exposure position.

As described above, the connection between the interlocking mechanism 27 and the strobe light emitting section 14 is easily performed by the forked connecting section 70 and the connecting pin 71 engaging with the connecting section 70. To the main body base 4 and the strobe light emitting section 14
Can be easily connected to the front cover 5 when the front cover 5 is attached to the main body base 4.

As shown in FIG. 9, when the strobe light-emitting portion 14 in the storage position is forcibly rotated to the exposure position by an external force, the contact protrusion 74 and the contact piece 73 do not abut. Therefore, the rotation of the outer case 61 is not transmitted to the interlocking lever 65, and there is no possibility that an unnecessary force is applied to the interlocking mechanism 27 to cause damage. Further, when the interlocking member 29 does not operate, the strobe light emission prohibition switch 48 is not turned off, so that unnecessary strobe light is not emitted. The torsion spring 66 acts between the outer case 61 and the interlocking lever 65, and forcibly returns the strobe light emitting unit 14 rotated to the exposure position to the storage position.
4 can be prevented beforehand.

As shown in FIG. 10, when the strobe light emitting portion 14 at the exposed position is forcibly rotated to the storage position by an external force, the contact piece 73 of the outer case 61 is moved to the position of the interlocking lever 65. In order to press the contact protrusion 74, the interlocking lever 65 slides the interlocking member 29 toward the rear side of the camera body 3 via the connecting pin 71. As described above, since the rotation of the strobe light emitting section 14 is absorbed by the sliding of the interlocking lever 65, there is no possibility that unnecessary parts are applied and the respective sections are damaged. Further, since the strobe light emission inhibition switch 48 is turned on by the stroke of the switching projection 49 by sliding the continuous image lever 65, no strobe light is emitted in the light emitting section chamber 16. Furthermore, since the coil spring 30 is extended by the sliding of the interlocking member 29, when the forcible rotation of the strobe light emitting unit 14 to the storage position is released, the strobe light emitting unit 14 is returned to the exposure position by the bias of the coil spring 30. it can.

If the strobe light emitting unit 14 is forcibly turned to the storage position while the strobe light emission prohibiting switch 48 has a conduction failure, the strobe light emitting unit 14 emits light in the light emitting unit chamber 16. However, since the light emitting unit room 16 has a large space in front of the strobe lens 15, there is no possibility of heat generation or smoking.

Next, the operation of the above embodiment will be described. In the assembly line of the camera 2, as shown in FIG. 1, a lens barrel 9 having a straight guide plate 22 mounted therein is incorporated into a fixed barrel 18 of the main body base 4. The interlocking mechanism 27 assembled on the line is attached. A strobe light emitting unit 14 assembled on another manufacturing line is rotatably attached to the light emitting unit chamber 16 of the front cover 5 using a rotating shaft 54.

When the front cover 5 to which the strobe light emitting section 14 is attached is attached to the front of the main body base 4, FIGS.
As shown in the figure, the connecting pin 71 of the interlocking lever 65 of the strobe light emitting portion 14 and the connecting portion 70 of the interlocking member 29 of the interlocking mechanism 27 engage through the opening 55 of the light emitting portion chamber 16 formed in the front cover 5. . Thus, the strobe light emitting unit 1
Since the connection between the camera 4 and the interlocking mechanism 27 can be easily performed, the suitability for assembling the camera 2 is improved.

The completed camera 2 is shipped after performing a function test and the like. A user who has purchased the camera 2 performs a shooting operation by loading a film cartridge into the camera 2. FIG.
When the camera 2 is not in use, the lens barrel 9 is collapsed inside the camera body 3 and the strobe light emitting unit 14 connects the strobe lens 15 to the camera body 3 as shown in FIG.
It is pivoted to the storage position to hide in. Power switch 10
When the power of the camera 2 is turned on by operating, the well-known lens barrel driving mechanism operates, and the lens barrel 9 is extended from the front surface of the camera body 3 as shown in FIG.

When the lens barrel 9 is extended from the camera body 3, as shown in FIG. 7, the rectilinear guide plate 22 attached behind the lens barrel 9 moves along with the lens barrel 9 along the photographing optical axis. It moves toward the front side of the camera body 3. When the rectilinear guide plate 22 moves toward the front side of the camera body 3, the pressing of the rectilinear guide plate 22 on the engaging pin 45 by the engaging piece 46 is released. The interlocking member 29 integrally formed with the engagement pin 45 slides toward the front side of the camera body 3 by the bias of the coil spring 30.

When the interlocking member 29 slides toward the front side of the camera body 3, the interlocking lever 65 in which the interlocking pin 71 is engaged with the connecting portion 70 of the interlocking member 29 is moved from the position shown in FIG. Rotate to the position shown. At this time, the interlocking lever 65 presses the contact piece 73 of the exterior cover 61 with the contact protrusion 74, rotates the strobe light emitting unit 14 clockwise in FIG. 6, and rotates to the exposure position shown in FIG. Move.

Thus, the strobe lens 15 of the strobe light emitting section 14 is parallel to the front surface of the camera body 3. When the interlocking member 29 moves toward the front side of the camera body 3, the switching projection 4 formed integrally with the interlocking member 29 is moved.
9, the holding of the strobe light emission prohibiting switch 48 in the ON state is released, and the strobe light emission prohibition switch 48 is turned off. The strobe circuit formed on the circuit board 32 is closed when the strobe light emission inhibition switch 48 is turned off, so that strobe photography can be performed.

The strobe light emitting section 14 is rotated to the exposed position by the urging of the coil spring 30 triggered by the movement of the engaging piece 46 caused by the extension of the lens barrel 9. Therefore, as shown in FIG. 10, even if the power of the camera 2 is turned on in a state where the strobe light emitting unit 14 is pressed to the storage position, the movement of the engagement piece 46 is not transmitted to the interlocking mechanism 27. As a result, there is no possibility that the stroboscopic light emitting unit 14 is damaged by the load caused by the extension operation of the lens barrel 9.

The user operates various operation switches provided on the back of the camera body 3 to switch the photographing mode, zoom magnification, photographing size, and the like. The composition is checked by looking through the viewfinder window on the eyepiece side. When the shutter button 13 is pressed halfway, the distance to the subject is measured by the distance measuring sensor, and the photographing lens 8 is moved to the focus position. At the same time, the brightness of the subject is measured by the photometric sensor. When the subject brightness is low, the flash circuit of the circuit board 32 automatically performs flash charging. When the shutter button 13 is depressed deeply, a shutter release is performed by a shutter mechanism incorporated in the lens barrel 9 to photograph one frame of the photographic film, and at the same time, a strobe light is emitted from the strobe light emitting unit 14 toward the subject. Light is emitted. The photographed photo film is wound into the film winding chamber 20 by the film winding mechanism.

As shown in FIG. 10, when the strobe light emitting portion 14 at the exposure position is forcibly rotated to the storage position, the contact piece 73 of the outer cover 61 is moved to the contact protrusion 7 of the interlocking lever 65.
Press 4. The interlocking lever 64 slides the interlocking member 29 toward the back of the camera. Therefore, when the rotation of the strobe light emitting unit 14 to the storage position is released, the strobe light emitting unit 14 is again turned to the exposed position by the urging of the coil spring 30. As described above, the drive source for rotating the strobe light emitting unit 14 to the exposure position in conjunction with the extension operation of the lens barrel 9 and the strobe light emitting unit 14 forcibly turned to the storage position return to the original exposure position. Since a common coil spring is used for the drive source to be driven, the number of parts can be reduced and the camera 2 can be configured at low cost. Further, the operation reliability can be improved as well as the suitability for assembly. When the strobe light emitting unit 14 is forcibly turned to the storage position, the switching protrusion 49 of the interlocking member 29 is not used.
Presses the strobe light emission prohibition switch 48 to turn it on, so that no strobe light emission is performed.

The strobe light emission inhibition switch 48 is
Since the strobe light emission unit 14 detects that the strobe light emission unit 14 is in the vicinity of the storage position and prohibits the strobe light emission, even if the strobe light emission prohibition switch 48 causes conduction failure and the prohibition of light emission in the storage position cannot be performed, the exposure position is not changed. Flash emission can be performed reliably, and photographing errors due to insufficient light quantity do not occur.

As shown in FIG. 3, when the power switch 10 of the camera 2 in use is turned off, the lens barrel 9 is collapsed into the camera body 3 by a well-known lens barrel driving mechanism. When the lens barrel 9 is retracted, the engaging piece 46 of the rectilinear guide plate 22 presses the interlocking pin 45 of the interlocking member 29 to prevent the interlocking member 29 from being biased by the coil spring 30 as shown in FIG. And slide it to the rear side of the camera body 3.

When the interlocking member 29 is slid toward the rear side of the camera body 3, the interlocking lever 65 in which the connecting pin 71 is engaged with the connecting portion 70 rotates counterclockwise in FIG. At this time, the interlocking lever 85 is
Then, the exterior cover 61 of the strobe light emitting unit 14 is pressed via the, and the strobe light emitting unit 14 is turned to the storage position shown in FIG.

Since the interlocking member 29 slid to the rear side of the camera body 3 presses the strobe light emission prohibition switch 48 by the switching protrusion 49 to be turned on, the strobe light emitting portion 14 emits light in the storage position. Never. Also, even if the strobe light emitting switch 48 fails and the strobe light emitting unit 14 emits strobe light in the storage position, the light emitting unit chamber 16 formed integrally with the front cover 5 can be used.
Since a shielding section 56 for shielding the strobe lens 15 of the strobe light emitting section 14 is provided therein, the strobe light does not enter the camera body 3 and does not adversely affect the photographic film. Is the strobe lens 15
Because there is a large space in front of the, there is no danger of heat generation or smoking.

As shown in FIG. 9, when the strobe light emitting unit 14 at the storage position is forcibly rotated to the exposure position,
Since the contact protrusion 74 does not contact the contact piece 73, the rotation of the outer case 61 is absorbed by the torsion spring 66 and is not transmitted to the interlock lever 65, and unnecessary force is applied to the interlock mechanism 27. It will not be damaged by the addition. Further, the interlocking member 2
9 does not work, the strobe flash prohibition switch 4
Since 8 is not turned off, unnecessary strobe light is not emitted. The torsion spring 66 acts between the outer case 61 and the interlocking lever 65, and forcibly returns the strobe light emitting unit 14 rotated to the exposure position to the storage position. It can be prevented beforehand. As described above, the torsion spring 66 for returning the strobe light emitting unit 14 that has been forcibly rotated from the storage position to the exposure position to the original position is replaced with the strobe light emitting unit 1 instead of the interlocking mechanism 27.
4, the torsion spring 66 and the coil spring 30
There is no need to balance the bias between

In the above-described embodiment, the movement between the storage position of the strobe light emitting unit and the exposure position is rotation, but other movement methods such as slide movement may be used. Further, the interlocking mechanism operates in conjunction with the straight guide member, but may interlock with the lens barrel.

[0051]

As described above, the camera according to the present invention is provided with the interlocking mechanism for moving the strobe light emitting unit between the storage position and the exposure position in conjunction with the collapsing and extending operation of the lens barrel. Therefore, it is possible to reliably move the strobe light emitting portion between the exposure position and the storage position in accordance with turning on / off of the power supply of the camera. Further, since the interlocking mechanism can be simplified, the suitability for assembly is improved, and the cost can be reduced. Further, operation reliability can be improved. In addition, an interlocking mechanism is attached to the base of the main unit, a strobe light emitting unit is attached to the front cover, and the strobe emitting unit and the interlocking mechanism are connected when the front cover is attached to the main unit base, so that the suitability of the camera assembly The cost can be reduced.

Further, when the strobe light emitting unit is moved from the storage position to the exposure position, the movement of the lens barrel is used as a trigger to perform the operation by the urging force of the exposure spring. Even if the lens barrel is extended or the strobe light emitting unit in the stowed position is forcibly moved to the exposed position by an external force in a state where the strobe light emitting unit or the interlocking mechanism is held down, the strobe light emitting unit or the interlocking mechanism is not damaged. In addition, the exposure spring can also be used as a spring that returns the strobe light emitting unit to the original exposed position when the strobe light emitting unit at the exposed position is forcibly moved to the storage position, so that the number of parts is reduced and the camera is reduced. Cost can be reduced.

Further, when the strobe light emitting portion at the storage position is moved to the exposure position without using the extension operation of the lens barrel, a storage spring for urging the strobe light emitting portion toward the storage position is provided. Since the strobe light emitting section is provided, there is no need to balance the biasing force between the storage spring and the exposure spring incorporated in the interlocking mechanism, and the precision required for the components can be reduced. Cost can be reduced.

Further, the detection switch detects that the strobe light emitting section is near the storage position and inhibits the strobe light emission, so that unnecessary strobe light emission at the storage position can be prevented. Prohibition of flash firing
Because it was done when the detection switch is conducting,
Even if the detection switch causes conduction failure and cannot prohibit light emission at the storage position, strobe light emission at the exposure position can be reliably performed, and photographing errors due to insufficient light quantity do not occur.
