DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for photographing a plurality of screens by a single release operation.

[0002]

2. Description of the Related Art When a moving subject is sequentially photographed with a time lag, it is possible to continuously obtain a photographic image in which the movement stops at each photographing moment. When such a technique is used in, for example, sports, it is very convenient because a constantly changing form can be observed as a still image. In view of this background, various continuous shooting cameras have been proposed. Typical examples include a camera that feeds a film at a high speed for each shooting and repeatedly shoots with a single lens, and a plurality of shooting lenses and an exposure aperture. Some cameras have a photographic lens that sequentially shoots a film with each photographic lens.

A continuous shooting camera disclosed in, for example, JP-A-2-105132 has been proposed as the latter having a plurality of photographing lenses and an exposure aperture. This continuous shooting camera
Each of the continuous shooting screens is arranged in a “field” shape through four exposure apertures, and a single release operation rotates a single rotary type shutter plate once to shoot a continuous shooting screen. It is like that. In addition, a continuous shooting camera “continuous shooting cardia” capable of shooting a continuous shooting screen of eight frames shifted in time by slits provided in two rotary shutter plates sequentially traversing eight exposure openings arranged in parallel. "Bune" (trade name) is manufactured and sold by the present applicant.

In this continuous photographing camera, two lenses, each of which is formed integrally with four lenses on a single lens plate formed of a transparent resin such as acrylic, are arranged in a straight line in the film feeding direction. The eight fixed apertures are provided so that their optical axes coincide with the front surfaces of the exposure apertures. Since the focal lengths of all eight lenses are the same, for example, if you want to check a golf swing form or baseball batting form, if you first frame the entire body of the subject, the form changes from the start to the end of the exercise. Can be photographed as a still image having the same angle of view every moment.

[0005]

However, the above-mentioned continuous shooting camera is suitable for shooting of sports or the like for observing a fine form, but is used for continuous shooting in a snapshot or the like in ordinary life. There is a drawback that the change of each frame of the screen is poor. SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-described problems of the related art, and has as its object to provide a camera capable of photographing a plurality of moving screens that change with each frame with a single release. .

When the shutter button 7 is operated, each time the traveling plate 32 moves a predetermined distance, the one end portion 33 falls down the step portion 31 sequentially, so that the shutter plate 32 moves stepwise. 32a
Exposure is performed across each of the exposure openings 11a to 11c. As shown in FIG.
5c is 35 (length in the film feeding direction).
It is the same as the horizontal length of one millimeter-sized screen. However, the vertical length is such that the upper side and the lower side of the 35 mm full size screen are each shielded with a width of 6 mm, and the image is taken. Therefore, such an exposure frame 15
When photographing is performed through a to 15c, as shown in FIG. 4, three continuous shooting screens 19a to 19c are exposed in a range of a screen 19d for one full size frame of the film 19 having a width of 35 mm. Continuous shooting screens 19a to 19 for each three frames
The horizontally long screen connected to c has a known screen size for panoramic printing (for example, 13.7 ± 0.4 mm × 36 mm).

After the completion of the exposure, the moved travel plate 27 and shutter plate 32 return to move in conjunction with the operation of the winding knob 9. A gear 40 that connects the rack gear 27d of the traveling plate 27 and the governor mechanism 30 is provided so as to mesh with a one-turn gear 39 that makes one rotation in conjunction with the operation of the hoist knob 9. The teeth of the one-rotation gear 39 are partially cut out, and the gear 40 is disengaged from the gear 40 in a photographing preparation state, and is engaged with the gear 40 by the operation of the winding knob 9 being started. The traveling plate 27 is returned and moved to the position in the photographing preparation state.

The return movement of the shutter plate 37 is performed by a half-rotating disk 41 which makes a half turn in conjunction with the operation of the winding knob 9. The semi-rotating disk 41 is disposed so that its rotating surface is parallel to the film feeding direction, and two pins 41a and 41b are provided on a straight line passing through the center of rotation so as to protrude forward. I have. The half-turn disc 41 is in a state where the two pins 41a and 41b are stopped at the positions shown in FIG. I will do it. A protruding piece 42 provided at the right end of the shutter plate 32 is located within the rotation range of these pins 41a and 41b.
The shutter plate 32 has the pins 41a, 4a from the position where the projecting piece 42 is in the exposure completed state to the position in the shooting preparation state.

After the traveling plate 27 has moved for a predetermined time, the one end 33 is moved from the first step 31a to the second step 35b.
And the slit 32a crosses the exposure opening 11a to perform the first exposure. In the first exposure, the photographic light flux of the subject reaches the continuous shooting screen 19a of the film 19 via the photographic lens 10a and the prism 23, so that the subject image by wide-angle shooting has been exposed. One end 3
When the traveling plate 27 continues to move for a certain time after the falling of the slit 3 to the second step 31b, the one end 33 falls from the second step 31b to the third step 31c, and the slit 32
The second exposure is performed when b crosses the exposure opening 11b. In the second exposure, the subject image is exposed on the continuous shooting screen 19b via the shooting lens 10b for standard shooting.

Then, the one end 33 is moved to the third step 31c.
Then, when the traveling plate 27 continues to move for a certain period of time, the one end 33 drops from the third step 31c and the engagement between the one end 33 and the step 31 is released. While the one end 33 is falling from the third step 31c, the slit 32c crosses the exposure opening 11c to perform the third exposure. In the third exposure, a photographic lens 10 for telephoto photography is used.
Through c, the subject image is exposed on the continuous shooting screen 19c.
After the completion of the third exposure, the movement between the traveling plate 27 and the shutter plate 43 stops. In this state, the shutter plate 43 is in contact with the inner wall of the main body base 13, and the traveling plate 27 is in contact with a predetermined stopper.

To prepare for the next photographing operation, the winding knob 9 is operated. When the winding knob 9 is operated, the film is advanced one frame in conjunction with this operation, and
The rotation gear 39 rotates. The rotation of the one-rotation gear 39 causes it to mesh with the gear 40, so that the traveling plate 27 is
Moves back against the bias of. Further, the half-turn disk 41 rotates in the direction of arrow A shown in FIG. 1 in conjunction with the operation of the winding knob 9. The rotation of the half-rotating disk 41 causes the pin 41 a to abut on the projecting piece 42 of the shutter plate 32, and then the projecting piece 4
Push 2 upward.

During the return movement of the shutter plate 32, the slits 32a to 32c provided in the shutter plate 32 cross the exposure openings 11a to 11c.
1 rotates the pin 41a to the lower contact portion 4 of the shielding plate 43.
6 is pressed along the arc portion 45 to move the shielding plate 43 leftward in FIG. 1 so that the exposure openings 11a to 11c are shielded by the shielding plate 43. Therefore, the exposure frames 15a to 15c
No exposure is performed on the film 19 located at the position.

When the operation of the winding knob 9 is continued, the pin 41 a provided on the half-turn disc 41 is
Is rotated to a position where it comes into contact with the optical disk, the shielding plate 43 is returned and moved so that the exposure openings 43a to 43b are positioned on the optical axes 22a to 22c. When the operation of the winding knob 9 is completed, the mesh between the one-rotation gear 39 and the gear 40 is released, and the movement of the traveling plate 27 stops while passing through one end 26b of the shutter interlocking lever 26. As a result, the shutter interlocking lever 26 turns right around the shaft 26a, and one end 26b of the lever 26 is prevented from moving in the biasing direction of the traveling plate 27 by the spring 28. The half-turn disk 41 stops when the pin 41a has rotated to the position of the pin 41b before rotation. Thus, the hoisting knob 9
