DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous shooting camera which performs a plurality of shots at short time intervals by one release operation.

[0002]

2. Description of the Related Art If a moving subject is sequentially photographed with a time lag, a photographic image in which the movement stops at each photographing moment can be obtained. Therefore, for example, in sports or the like, the form at each moment can be observed as a still image, which is very convenient.

In order to obtain such a continuous shooting function, as in a single-lens reflex camera, it is only necessary to wind up the film one frame at a time by a motor and drive the shutter in synchronization with this. However, since the film is wound up at a high speed, the sound is noisy, and there is a problem in a scene requiring quietness such as a golf swing. If the number of frames to be used for one continuous shooting is increased, the consumption of the film increases, and it is not possible to perform many continuous shootings with one film. Further, since a print photograph is usually divided into frames, there is a problem that even a continuous shooting scene becomes a separate print photograph and takes time to organize.

[0004] Under these circumstances, Japanese Patent Publication No. 41-1335
No. 2, JP-A-2-105132, etc.
There has been proposed a continuous shooting camera that divides a millimeter-size screen into upper, lower, left, and right portions and sequentially captures the divided frames.

[0005]

However, in the case of using the continuous shooting camera described in each of the above-mentioned publications, if a normal service print is performed, each frame becomes a print photograph in which the frames are arranged vertically, horizontally, and continuously. Not only is the character difficult to understand, but the actual size of each frame is too small to obtain a print photo that is sufficient for observation. Then, in order to make each divided frame into a print photo of the size of a service print, request a magnified print and cut the finished print photo for each frame, or do not request a special trimming print. In any case, it was not possible to easily obtain a print photograph of a continuous shooting scene that was sufficient for observation.

In the continuous shooting cameras described in the above publications,
Since an independent photographic lens is used for each frame, it must be precisely adjusted and attached, and there is a possibility that a photograph with a different focus for each frame may be obtained.

[0007] Further, when three to four frames are to be printed on a 35 mm full size screen, if the full size screen is simply divided into equal parts and photographed, the following problem occurs. In a normal printer, the entire area of a 35 mm full-size screen is not printed on color paper, but the periphery of the screen is cut. Therefore, for example, when a 35 mm full-size screen is divided into four frames and photographed, the outer edges of the frames at both ends are cut, and the frame at the intermediate portion and the frames at both ends are the main subject. The position is shifted, which is not preferable as a continuous photograph.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is possible to easily obtain a continuous photograph of a sufficient size without requesting a special print.
Continuous shooting of many scenes can be performed on a book film, and the position of the main subject of each frame does not shift during printing, and the mounting adjustment of each lens can be easily performed. It is an object of the present invention to provide a continuous shooting camera as described above.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention recently provides a panoramic print that enlarges and prints a horizontally long screen area at the center while partially ignoring the upper and lower sides of a 35 mm full size screen. Paying attention to the widespread use of the service, the landscape screen for panoramic printing is divided into a plurality of sections only in the horizontal direction, and the divided frames are sequentially photographed from the end.

[0010] Further, the present invention also provides a method in which a screen for panoramic printing is made continuous for two frames, and a horizontally long screen for two frames is divided into a plurality of pieces only in the horizontal direction, and shooting is performed sequentially. It is an effective means to achieve the purpose.

A lens for photographing a plurality of frames is integrally formed on one lens plate to form a photographing lens. At least one photographing lens is used to adjust the mounting of each lens. Is omitted, and this can be easily attached.

In addition, the center of the photographing lens corresponding to each of the divided frames is brought closer to the center of the 35 mm full size screen, and the exposure frames at both ends are wider than the other exposure frames, so that normal printing can be performed. In the case of printing exposure using the same, the position of the main subject in each frame can always be kept constant.

[0013]

In the panoramic print service in which the upper side and the lower side of the 35 mm full-size screen are partially ignored, printing is performed at twice the enlargement ratio of a normal service print, so each divided frame is used for observation. It becomes a print photo of a sufficient size. Moreover, since each of these frames is obtained as being continuous in the horizontal direction as time elapses, the reproducibility of the continuous shooting scene is excellent. Further, since the taking lens is integrally formed, it is possible to easily attach each of the lenses and easily align the focal positions of each of the lenses. Also,
Since the center of each photographing lens is located inside, when using a general print that cuts and prints the periphery of a 35 mm full size screen, the position of each main subject of the obtained continuous shot frames is always constant within the frame. Can be done.

[0014]

1 to 3 show a continuous photographing camera using the present invention, eight photographing lenses 3a to 3h are mounted on a front surface of a camera body 2 in a horizontally arranged manner, and light of each lens is provided. The axes are parallel. Shooting lenses 3a-3
d is formed integrally with one lens plate 4 formed of a transparent resin such as acrylic, and the photographing lenses 3e to 3h
Is integrally formed with the other lens plate 5. These are adjusted so that the focal positions of the respective lenses become substantially equal by forming a mold.

A camera lens 3 is provided inside the camera body 2.
A shutter substrate 7 having eight exposure openings 6a to 6h corresponding to a to 3h is fixed. The inner diameters of the exposure openings 6a to 6h are all equal. Shafts 8 and 9 are implanted in the shutter substrate 7 and rotatably support disk-shaped shutter plates 10 and 11, respectively. Gears 10a, 11 are provided on the outer circumference of the shutter plates 10, 11 over the entire circumference.
a are formed and mesh with each other. A stepping motor 12 is fixed to the front side of the shutter substrate 7, and a driving gear 13 fixed to the shaft of the stepping motor 11
It is in mesh with the gear 10a of the shutter plate 10.

As shown in FIG. 4, the shutter plate 1
0 and 11 each have two slits 15a and 15
b, 16a and 16b are formed. Slit 15
a and 15b are on the same line segment passing through the center of the shutter plate 10. Similarly, the slits 16a and 16b
On the same line passing through the center of. The slit 15
The slits a and 15b or the slits 16a and 16b do not necessarily have to be on the same line passing through the centers of the shutter plates 10 and 11, and can be positively shifted in consideration of the photographing timing.

These slits 15a, 15b, 16
The slit length of a and 16b (the length in the radial direction of the shutter plate) is equal to or larger than the inner diameter of the exposure openings 6a to 6h.
Further, the slit width (width in the circumferential direction of the shutter plate) of each outer slit 15a, 16a and the inner slit 15
The slit widths of b and 16b are changed according to the distance from the axes 8 and 9, respectively.
Assuming that the slit width of the slits a and 16a is 1 mm, the slit width of the inner slits 15b and 16b is about 0.7 mm.

The rotation of the shutter plate 10 causes the slit 15a to move clockwise from the illustrated origin position P _0, and when passing through the first exposure position P ₁ , exposes the aperture 6.
a is opened and closed. Shutter plate 10 continues to rotate, the slit 15b is exposed opening 6b is opened and closed when it passes through the second exposure position P _2. And the slits 15b, 15a
Each time passes through the third exposure position P ₃ and the fourth exposure position P ₄ , the exposure openings 6 c and 6 d are sequentially opened and closed.

When the shutter plate 10 starts to rotate clockwise, the gears 10a and 11a mesh with each other to cause the shutter plate 11 to rotate.
Rotates counterclockwise. After the slit 15a passes the fourth exposure position P _4, the slits 16a of the shutter plate 11 rotates from the home position Q ₀ to the fifth exposure position Q _5, the exposure opening 6e during passage is opened and closed. Since the rotation of the shutter plate 10 is continued until the slits 15a and 15b reach the origin position P ₀ again, the shutter plate 11 continues to rotate counterclockwise in conjunction with the rotation, and the sixth exposure position Q ₆ , Seventh exposure position Q ₇ , eighth exposure position Q ₈
Exposure openings 6f, 6g by slits 16a, 16b
6h are sequentially opened and closed. Note that the stepping motor 1
By the drive control 2, the time from opening and closing of the first exposure opening 6a to opening and closing of the last exposure opening 6h is about 1 second.

As shown in FIG. 3, between the patrone loading chamber 18 and the winding chamber 19 provided in the camera body 2, each is divided by a partition wall 8 along the film feeding direction. Exposure frames 21a to 21h are formed.
From the exposure frame 21a to the exposure frame 21d,
e to the exposure frame 21h in the horizontal direction are 3
It has the same horizontal length as one frame of a 5 mm full size screen. In about half of the vertical 35 Mirifuru size frames the length of each exposure frame 21a to 21h, the film 20
Is provided at a position where a central portion in the vertical direction is exposed. Therefore, when photographing is performed through the exposure frames 21a to 21h, as shown in FIG. 1, the screens 22a and 22b for one full size frame of the 35 mm wide film 20 are displayed.
In each of four continuous shooting screens 24a to 24d, 24
e to 24h are exposed.

It is to be noted that the continuous shooting screen 24a of each four frames
To 24d or 24e to 24h are connected to each other in a panoramic print screen size obtained when the upper side and the lower side of the screen for one full size frame are shielded with a width of 6 mm, respectively. For example, 13.7 ±
0.4 mm x 36 mm). Then, as shown in FIG. 3, the continuous shooting screen 24d is formed by the central partition wall 25.
A space is provided between and the continuous shooting screen 24e. Furthermore, the horizontal size of the four continuous shooting screens 24a, 24d, 24e, and 24h is the same as the other continuous shooting screens 24b, 24c, 24f, and 2
The shape of the exposure frame is determined so as to be longer than 4 g.

The film 20 is wound up by a counterclockwise rotation of a spool 28 provided in the take-up chamber 19, and is loaded into the patrone chamber 18.
Drawn from. A film winding motor 30 is built in the spool 28, and its driving force is transmitted to a film feeding mechanism 32 via a gear 31. The film feeding mechanism 32 receives the driving force from the gear 31, drives the spool 28 via the gear 33 when the film is wound, and the rewind fork 3 via the gear 34 when the film is unwound.
5 is driven.

A sprocket 36 is engaged with the film perforation 20a, and is rotated by feeding the film 20. The sprocket 36 is integrally connected with a signal plate 37 having a radially formed through-hole slit.
The rotation amount of the sprocket 36 is detected by monitoring the rotation of the sprocket 36 with the photo sensor 38. When the film is wound, the drive of the motor 30 is stopped when it is detected by the signal plate 37 and the photosensor 38 that the feed amount of the film 20 has reached 35 mm full size two frames.

The operation of the continuous shooting camera having the above configuration will be described. When the shutter button 40 is pressed once after the film 20 is loaded, the stepping motor 12 starts driving, and the shutter plate 10 rotates clockwise in FIGS. At the same time,
The engagement of the gears 10a, 11a causes the shutter plate 11 to rotate counterclockwise.

When the shutter plate 10 is at the origin position P shown in FIG.
_By rotating from ₀ to the first to fourth exposure positions P ₁ , P ₂ , P ₃ , P ₄ , the slits 15 a, 15 b open and close the exposure openings 6 a, 6 b, 6 c, 6 d sequentially, and the film 20. , The continuous shooting screens 24a, 24b, 24c, 24d are exposed. Immediately after continuous shooting screen 24d is exposed, the shutter plate 11 reaches the home position Q ₀ to the fifth exposure position Q _5, continue to pass the sixth to eighth exposure position Q _6, Q _7, Q ₈ Therefore, the exposure openings 6e, 6f, 6g, 6h are sequentially opened and closed by the slits 16a, 16b.

The slits 15b, 16b inside the shutter plates 10, 11 are connected to the slits 15a, 16
Although the peripheral speed is slower than a, the slits 15b, 16b
, The exposure amount of each of the continuous shooting screens 24a to 24h is kept constant. If the shutter plates 10 and 11 are rotated once at a constant speed, and the shutter opening time for photographing each frame of the continuous shooting screen may become long, the driving pulse supplied to the stepping motor 12 may be increased. May be varied, and the shutter plates 10 and 11 may be rotated at a high speed at the moment of exposure.

When the shutter plates 10 and 11 make one rotation and each slit returns to the original position again, the driving of the stepping motor 12 stops, and one continuous shooting is completed. In order to always stop the shutter plates 10 and 11 at the origin position, for example, a reflection piece for detecting the origin is fixed to the shutter plate 10 and detected by a reflection type photo sensor to control the stop of the stepping motor 12. Should be performed. At this time, once the shutter plate 10 is slightly passed through the origin position, and then the shutter plate 10 is reversed and returned to the origin position, the shutter plate 10 can be accurately returned to the origin position.

When the continuous shooting screens 24a to 24h of eight frames are shot on the film 20, the film feeding mechanism 32 is operated upon receiving the shooting completion signal, the motor 30 is driven, and the feeding of the film 20 is started. Be started. Then, when the signal plate 37 and the photo sensor 38 detect the feeding of two frames of 35 mm full size, the motor 30 is stopped and the apparatus enters a standby state for the next photographing.

FIG. 5 conceptually shows the film 20 photographed as described above. As described above, the continuous shooting screens 24a to 24d of four frames have the same size as the screen size for panoramic printing. Therefore, by performing the panoramic print processing up to this point, the continuous shooting screens 24a to 24d are printed in the size of two service prints, and the individual continuous shooting screens 24a to 24d are also sufficiently large.

At present, the panorama print service is provided for each frame of a 35 mm full-size screen, and as shown in FIG. 46 is obtained. Therefore, if two print photographs 45 and 46 are connected, a continuous photograph is obtained by one continuous photographing, and each frame is arranged side by side with the passage of time. Is advantageous.

At the time of the panoramic print processing, a negative mask having an opening size indicated by a two-dot chain line 40 in FIG. 5 is used, and vignetting occurs at the ends of the continuous shooting screens 24a and 24d at both ends. If this is to be actively prevented, see FIG.
The lens plates 58 and 59 in which the positions of the photographing lenses 60a to 60h are changed as shown in FIG. In FIG. 7, the same components as those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted. When the 35 mm full size screen is divided into four, the photographing lenses 60a, 60
The positions of d, 60e and 60h are closer to the center than the ones in the above embodiment, and the distance between the lenses is L1. Also,
The exposure frame is formed wider at both ends than at the middle. As a result, each frame 61a to 61a on the negative film
The width of 1h is b, a, a, b, b, a, a, b (a <b)
However, even when printing is performed by a normal printer, each frame is printed in the same size, and the frames 61a and 61 at both ends are printed.
The main subject positions 1d, 61e, and 61h are almost at the center, similarly to the frames 61b, 61c, 61f, and 61g of the other intermediate portions, so that a preferable continuous photograph is obtained. FIG. 8 shows the relationship between the image photographed in this way and the obtained print. In FIG. 8, reference numerals 62a to 62h denote respective exposure frames, and reference numeral 63 denotes a screen range exposed to the negative film 64 through the exposure frames 62a to 62h, and the screen range 63 and the entire exposure frames 62a to 62h are shown. What is size
Almost match. Reference numeral 65 denotes a printing range, and reference numerals 66a to 66h denote exposure openings.

In the above-described continuous shooting camera, continuous shooting can be performed by reversing the stepping motor 12. When the stepping motor 12 is rotated in the reverse direction to perform continuous shooting, shooting is performed in the order of the continuous shooting screens 24h, 24g, 24f,... 24a. Therefore, for example, in the case of continuously photographing a golf swing of a left-handed player, if the mode switch 50 (see FIG. 2) is switched to the left-handed mode and the stepping motor 12 is reversed to perform continuous shooting, one shot is performed. Two printed photos 4 as shown in FIG. 9 for shooting
7, 48 are obtained. In this way, by arranging the frames in order from the right with the passage of time, it is possible to reproduce a continuous shooting scene that is easy to see in accordance with the direction of the movement of the left-handed player.

In the above, an example has been described in which two continuous frames of 35 mm full size are used in one continuous shooting, and a continuous shooting screen of eight frames is photographed therein, but the length of the film used in one continuous shooting is described. The frame length can be set to one or three frames of a 35 mm full size screen, or the number of frames of a continuous shooting screen can be set to three or five frames for one 35 mm full size screen. Also, as for the shutter mechanism for sequentially exposing the continuous shooting screen, not only the two shutter plates 10 and 11 are used in a rotary manner as described above, but also various types can be used. It is possible.

Further, although there is a possibility that each frame becomes small and observation becomes somewhat difficult, it is necessary to check continuity.
As shown in FIG. 10 when viewing the gafilm from the base surface side ,
The four frames 70a to 70d and 70e to 70h can be photographed vertically. Also in this case, the frames 70a, 70d, 70d at both ends are so arranged that the position of each main subject does not change significantly even when printing is performed by a normal printer.
e, the exposure opening 84 of 70h is slightly eccentric from the center, the exposure opening 84 of the upper four frames 70a to 70d is slightly lowered from the center, and the exposure opening 84 of the lower four frames 70e to 70h is slightly raised from the center. . Thereby, the main subject position of each frame at the time of printing can be imprinted on a fixed position of each frame. Reference numeral 72 in FIG. 10 indicates an opening range of the negative mask, and a hatched portion is a printing range. Reference numeral 73 denotes a range of one frame of the film recorded on the negative film, which substantially matches the size of the entire exposure frame of the continuous shooting camera. In this case, the shutter plates 80 and 81 of the continuous shooting camera and the lens plate 8
FIG. 11 shows the positional relationship among the exposure frames 85a to 85h, the exposure openings 84, and the exposure frames 85a to 85h. The shutter plates 80 and 81 are
It is rotated by a stepping motor 88 via a drive gear 86 and an intermediate gear 87.

Further, as shown in FIG.
Exposure frame 85 which partitions the ~70h a~ 85 d of the partition plate 91
Is separated from the film 92 and the gap L2 is provided so that the exposure of the end portions of the adjacent frames can be overlapped, and a black frame (unexposed) can be prevented between the frames during printing. That is, when the area between the frames 70a to 70h is printed by double exposure, this portion becomes whitish, and a preferable continuous photograph can be obtained.

In the above embodiment, two lens plates integrally formed with four lenses are used. However, four lens plates integrally formed with two lenses or eight lenses are integrally formed. It goes without saying that the same effect can be obtained even if one molded lens plate is used.

[0037]

As described above, according to the continuous shooting camera of the present invention, the screen for panoramic printing is divided into a plurality only in the horizontal direction, and these divided frames are temporally shifted sequentially from the end. Since the continuous shooting screen is photographed, the panoramic print service can be applied as it is without making a special print request, so that a print photograph having a size sufficient for appreciation can be obtained. In addition, since the frames obtained by continuous shooting are arranged from the end in order of elapse of time, a continuous shooting scene in which continuity is easily recognized can be reproduced.

Further, by integrally molding a plurality of photographing lenses, the focal positions of these lenses can be easily adjusted, and the mounting and adjustment thereof can be simplified. Also, by decentering the photographing lenses at both ends of the plurality of photographing lenses toward the center side, even when printing exposure using a normal print, the main subject position of each frame becomes almost a fixed position on the screen, which is preferable. You can get continuous shots.
