Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a camera, and particularly to a bifocal camera with a flash photography device.

[Background of the invention]

In general, in cameras equipped with a flash device, if the distance between the light emitting part of the flash device and the window for the photographic lens is narrow, red-eye phenomenon occurs during flash photography (the light emitted from the flash device is regularly reflected on the retina of the human eye, which is the subject). However, it is known that the reflected light passes through the photographic lens and is exposed to the film, resulting in a phenomenon in which the human eyes in the resulting photograph turn eerily red. . This phenomenon is more likely to occur as the amount of light emitted by the tortoise flash device increases and as the focal length of the photographic lens increases (that is, as the photographic magnification increases).

Therefore, in the past, it has been avoided to equip compact cameras with a flash device with a narrow distance between the flash device light emitting part and the photographing lens window, such as compact cameras with a flash device.・In response to the demands of customers seeking improved performance, expanded applications, and money for standard cameras, we have developed a bifocal converter with a flash device that is equipped with a long focal length lens capable of telephoto shooting in addition to the conventional short focal length lens. Compact cameras are becoming increasingly popular, and as a result, the red-eye phenomenon in such compact cameras has become a problem.

Many proposals have been made regarding cameras with a flash device and switchable focus, but there are almost no proposals aimed at preventing this red-eye phenomenon, and only one proposed by a busy applicant is known. This proposal was made in 1974-5.
It is published as Publication No. 3429, and this publication includes:
A camera has been disclosed that has a structure in which a flash device light emitting section is moved in a direction away from a photographic lens window when a photographic lens with a large focal length is used.

This proposal is extremely effective in preventing the occurrence of red-eye, but when the focal length changes significantly (for example, from f = 35 mg to f = 70 m), it is difficult to There were five problems that made it difficult to realize in small cameras such as digital cameras. That is, in the above case, in order to realize the proposed feature 'a', the moving distance of the light emitting part must be set to a considerably large value;
When the light emitting part is moved, the inside of the camera cannot be seen. 5. The exterior part must be made larger, so the camera's controller/
'Putability is impaired, and since the amount of movement of the light emitting part is large, the guiding mechanism of the slide case supporting the light emitting part becomes complicated and unreliable, resulting in an increase in the size of the camera. There was a problem.

[Purpose of the invention]

An object of the present invention is to provide a novel multifocal camera equipped with a flash device, which is extremely L-shaped but does not cause red-eye phenomenon even during nighttime telephoto shooting.

[Summary of the invention]

The camera according to the present invention has an exterior part provided with at least two photographic windows, one in which a short focus lens system is disposed and the other in which a long focus lens system is disposed; The window in which the lens system with the shortest focal length is located is located closest to the light emitting part of the flash device, and the window in which the lens system with the longest focal length is located is located furthest from the light emitting part of the flash device. It is characterized by being placed at a certain position. In addition, the camera according to the present invention is provided with a rear (protective cover) that opens each of the windows in sequence according to the shooting situation, and is also provided with a lens for photographing a subject that moves while staying in the above-mentioned condition. It is characterized by the presence of That is, in the camera of the present invention having the above-mentioned structure, since the window of the long focus lens system is located far from the light emitting part of the flash device, there is no risk of causing a red eye phenomenon even during flash telephoto shooting. Since the lens for photographing the subject is configured to move from the short-focus window to the long-focus window, it is more compact than a known camera (see the above-mentioned publication) in which only the flash unit's light emitting part moves. Therefore, the amount of movement of the light emitting part is much smaller, and therefore the outer shape is smaller.

The focus can be adjusted at any time.

27 and 28 are slide levers connected to the protection plate 4 (barrier) via pins 4a and 4b, and these slide levers 27 and 28 have long grooves 27m and 2
It is supported by pins 29 and 30 of the structural member fitted in 8a, and biased to the left in FIG. 1(c) by springs 31 and 32. The slide levers 27 and 28 are provided with protective plates 4 as described above.
Arms 27b and 28 connected to projecting bins 4a and 4b of
In addition to b, there are arms 27c and 28c that engage with the protruding pin 2b of the slide cover 2, arms 27d and 28d that engage with the unillustrated bins provided on the mirror holding frame 21, and an engaging member 19d of the lens holding frame 19. Arms 27, which engage with the respective arms 27, are provided. The operation of these parts and the operation of the optical path system of the camera will be explained later.

FIG. 4 is a perspective view showing the lens holding frame 19 and its related structural parts, and FIG. 4 (,) shows the lens holding frame in the state shown in FIG. 1(c) and FIG. FIG. 4(b) shows the attitude of the lens holding frame in the state shown in FIG. 3(C) (that is, during long focus photography).

The lens holding frame 19 is in the shape of a scoop, and the shaft 19m, which is the center of rotation thereof, is rotatably and axially movably supported at the bearing portions of the structural members 33 and 34.
It is urged forward with an axial force in FIG. 4(,) by a spring 35 fitted in the. 44! l 19 a
The distal part of the cam follower 19b is counted as a spherical cam follower 19b, and the cam follower 19b is a cylindrical end cam 36.
is pressed against the cam surface 36c of the spring 35 by the force of the spring 35. The end cam 36 is connected to the shaft 1 by an integrated gear 36b.
5 so that it can rotate around an axis parallel to 9a. A hole 36m is provided in the center of the gear 36b, and the gear 36b is rotatably supported on the shaft of a structural member inserted into the hole 36a.
It is designed to be rotationally driven by an AF drive device (not shown) via gears 39 in K-mesh. A screw 40 protrudes from the front surface of the gear 36b and is attached so as to move in the front and back direction when rotated relative to a structural member (not shown).
, therefore, by rotating the screw 40, the end cam 3
6 can be moved in the axial direction in the figure together with the lens barrel 19, and as a result, the axial position of the lens holding frame 19 can be slightly changed at a certain rotational phase of the end cam 36. Such an operation means that the lens holding frame 19 is minutely adjusted along the axial direction of the lens, that is, the focus of the lens 18 can be adjusted by the screw 40. Note that the axis of the screw 40 is aligned with the axis of the shaft 19m, so even when the screw 40 is rotated, the pressure contact point between the cam surface 36c and the cam follower 19b is on the axis of the screw 40. There is no risk that the cam 36 will tilt.

The lens holding frame 19 includes a retainer 19d provided at the tip of the arm 19e and a protrusion 19e provided at the opposite end thereof, and is biased by a spring (not shown) in the eV direction in the figure about the shaft 19a. 1 (c) and 2 (
As shown in c), it engages with the arm 276 of the slide lever 27 during non-shooting and short-focus shooting, and the protrusion 19
Similarly, c is the stone zJ? of the structural member during non-photography and short-focus shooting. 37 as shown in FIG. 1(c) and FIG. 2(e) to position the lens holding frame 19 at a predetermined first position, and at the time of long focus photography,
), the lens holding frame 19 is positioned at a predetermined second position by contacting another stone 438 of the structural member like a water drop.

Next, the operation of each part in the camera of the present invention having the above structure will be explained.

When not photographing and when stored, the slide cover 2 is pushed toward the battery compartment LD side to a position that hides the release button 41, as shown in FIG. (barrier), while
The finder eyepiece hole 2a is closed by a rear decorative plate 9, as shown in FIG. 1(b). The main parts inside the camera are in the state shown in FIG. 1(b) and FIG. 1(C).

When performing short-focus photography, the slide cover 2 is pulled out to the right from the state shown in Fig. 1 (,), and when the slide cover 2 stops at the first position where the click stop is applied,
In the state shown in FIG. 2(a), the photographing lens aperture 2c appears and the flash is opened. The AF light emitting window 3c and AF light receiving window 3d, which are closer to the grotector 3a, are opened and the
), the finder eyepiece hole 2c is opened and the release button 41 is exposed, making short-focus photography possible.

There is almost no change in the internal mechanism of the camera during the transition from the state shown in Figure 1 to the state shown in Figure 2, but Figure M2 (c)
As shown in FIG. 2, the pin 2b integrated with the slide cover 2 has moved to the right side compared to the state shown in FIG. portion 8b is aligned with the photographing lens 18.

Release yl in this state? When the button 41 is pressed, the light projected from the AF light projection window 3c towards the subject is reflected by the subject and enters the AF light receiving window 3d, and passes through the AF light receiving lens 10 arranged behind the window 3d to the light receiving element. After being imaged on 12 and converted into an electrical signal by the light receiving element 12,
The distance to the subject is calculated by a processing unit installed in the camera. As a result, when the distance to the subject is calculated, a drive device (actuator) (not shown) moves the gear 36b via the gear 39 shown in FIGS. 4(a) and (b) based on a command from the calculation device. The end cam 36, which is rotated and is integral with the gear 36b, is also rotated. For this reason, the cam surface 36c
The cam follower 19b that is in contact with the cam surface changes in the axial direction of the shaft 19m, and the contact position with the cam surface changes, so that the photographing lens 18 is moved against the film F of the photographic lens arrangement 1c. The lens is positioned in the front-rear direction and automatic focusing is performed on the subject. In this case, the posture of the lens holding frame 19 will be as shown in FIG. 2(c) and FIG. 4(,).

Next, the shutter 23 is opened and the subject light is transmitted to the photographing lens 18.
The light passes through and reaches the aperture 1c, and an image is formed on the film F within the aperture 1c, and the film F is exposed, thereby completing short-focus photography. In this case, the optical path for viewing the subject from the finder eyepiece hole 2a is shown in Figure 2 (
As shown in b), the eyepiece 13. The frame consists of a reflective lens 14 and an objective lens 15 for short focus.

In the above case, even if flash photography is performed, there is little risk of red-eye occurring because the focal length of the photographic lens is short. On the other hand, when performing long-focus photography (that is, telephoto photography), when the slide cover 2'fr is pulled out from the position shown in Figure 2 (a) to the right side, the click stop will click at the position shown in Figure 3 (a). Stop when it starts. In this state, Figure 3 (
a) Show K, 5, Stro? The long focus lens aperture 8a located far from the protector 3a opens, and the AF floodlight window 3c also has a straw located far from the protector 3a.
The AF unit fixed to the main body is located in the AF light receiving window 3d, and each part inside the camera has a relative positional relationship as shown in FIG. 3(b) and FIG. 3(c).

The following describes the operation of each part when changing from the state shown in Fig. 2(b) and Fig. 2(e) to the state shown in Fig. 3(b) and Fig. 3(c). This will be explained with reference to FIGS. 4 to 4.

In the state shown in FIG. 2(c), the slide cover 2t
- When moved to the right, the pin 2b integrated with the slide cover 2 also moves to the right and engages the arms 27c and 28a of the slide levers 27 and 28, respectively, and then the slide levers 27 and 28t - the springs 31 and 32. Move it to the right against the tension. Therefore, the protective cover 4, which is connected to the slide levers 27 and 28 via the bins 4a and 4b, also moves to the right side together with the slide lever (that is, together with the slide cover 2), and the short focus lens opening 8b of the front decorative plate 8 moves to the right side. to shield. On the other hand, slide lever 2
As the arms 7 and 28 move to the right, the engagement between the arm 27a and the engagement element 19d of the lens holding frame 19 is disengaged, so the torque that urges the lens holding rod 19 counterclockwise around its axis 19& is lost. As a result, the lens holding frame 19 is rotated clockwise about the shaft 19m by the force of the spring (not shown). Then, when the slide lever 27 further moves to the right and the movement of the slide cover 2 is click-stopped, the protrusion 19c of the lens holding frame 19 is moved to the center/f38 of the structural member, as shown in FIG. 3(C).
It comes into contact with. As a result, the lens holding frame 19
As shown in FIG. 3(b), FIG. 4(b), and FIG. 3(c), is positioned on the axis that coincides with the optical axis of the comparator lens e25 for long focus photography.

Meanwhile, in the process of moving the slide levers 27 and 28 from the position shown in FIG. 2(c) to the position shown in FIG. 3(c), the arms 27d and 28d of the slide 9 levers 27 and 28 are By the rightward movement of the arms 27d and 28d, the mirror holding frame 21 is rotated clockwise about its axis 21a in FIG. 2(b), and as shown in FIG. 3(b). The state is converted to the state shown in FIG. 3(c). As a result, the subject light entering from the long focus lens opening 8a passes through the two-shaped optical path of the photographing lens 18, the shutter 26, the converter lens 25, the fixed reflection mirror 24, and the movable mirror 20, and reaches the γ percha 1cK. .

As mentioned above, in addition to the optical system related to the photographic lens, the optical system related to the finder also has the following J during long focal length shooting.
:) will be converted to

In other words, from the state shown in M2 diagram (b), the sliding force・9
-2 to the right, the switching lever 17, which is engaged with a cam (not shown) formed on the camera body l and is biased clockwise about the shaft 17a in FIG. 2(b), As the slide cover 2 moves to the right, it is gradually disengaged from the cam, so that it rotates in the 8-8 direction around the shaft 17a, and the slide cover 2 is rotated as shown in FIG.
When the switching lever 17 is moved to the position b), the switching lever 17 is moved to the third position.
It is rotated to the position shown in Figure (b).

On the other hand, the long focus objective lens 16, which is biased clockwise around the shaft 1 (5a') by a spring (not shown), is not rotated by the side wall surface of the slide cover 2 in the state shown in FIG. 2(b). However, as the slide cover 2 moves to the right from the position shown in Fig. 2(b), it gradually becomes uncoupled from the slide cover 2, so that the slide cover 2 moves to the position shown in Fig. 3(b). When the position shown in FIG.
- Move to til, rotated about 90 degrees clockwise from the center.

Therefore, the optical path of the finder during long focus photography is shown in Figure 3 (b).
), it is composed of a combination of an eyepiece lens, el 3 , a frame reflection lens 14, and a long focal length objective lens 16.

Note that, as described above, the photographing operation after the optical system of the photographing lens 18 and the optical system of the finder are set for long-focus photographing (that is, the automatic focus p! section operation after pressing the release button 41, etc.) ) are as described above, so their explanation will be omitted.

As described above, during long-focus photography, the subject light enters the photographing lens opening 8a located sufficiently away from the lens protector 3a, so the camera of the present invention prevents the red-eye phenomenon even during long-focus flash photography. There is little risk of this occurring, and high-quality images can be obtained.

Furthermore, since the photographing lens also moves in a direction away from the flash light emitting section during long focus photography, the rate of change in focal length can be increased without significantly moving the flash light emitting section. In the embodiment, the flash light emitting section is movable, but the flash light emitting section may be fixed.

〔Effect of the invention〕

As shown in the above embodiments, in the camera of the present invention, the shortest focus lens system is disposed within the photographing lens aperture at the position closest to the flash light emitting section, and the long focus aperture is disposed within the photographic lens aperture at the closest position to the flash light emitting section. Because it is located far away from the flash unit, you can take high-quality photos without the risk of red-eye even when using a long focal length lens. Since the lens is also configured to move in the opposite direction to the moving direction of the light emitting section, the relative distance between the photographing lens section and the light emitting section can be changed significantly, and as a result, the light emitting section can be moved. Even if the camera has a multi-focal switching type structure, it is possible to realize a compact camera without sacrificing the compactness and cost of the camera.
