Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous shooting camera capable of selectively performing one-shot shooting and continuous shooting.

[0002]

2. Description of the Related Art Conventionally, a continuous shooting camera has been proposed in Japanese Patent Laid-Open No. 4-269729. This continuous shooting camera rotates two shutter disks simultaneously with a stepping motor,
Eight frames of images are continuously exposed in a horizontal row in two screens by sequentially crossing eight shutter openings in which two slits are provided in each of the shutter disks and arranged horizontally. Each frame has a size of approximately 13 x 8.3 mm, and both edges of one screen are slightly cut when printing, so 13 x 3
It has a panoramic size of 6 mm. From the exposed photographic film, a panoramic print photograph of 89 × 254 mm is produced by printing each screen during printing. Then, by observing the obtained two print photographs side by side, it is possible to obtain a photographic image in which the movement of the subject has stopped at each moment, so that various motions can be easily analyzed.

By the way, in the continuous shooting camera described in the above publication, the exposure time for the slit to cross the shutter opening is set to 1 in order to stop the motion of the subject playing sports and take a picture.
/ 250sec or more is set. Then, the microcomputer controls the stepping motor to intermittently rotate the shutter disk so that the exposure interval is different from the exposure time, and the continuous shooting time of Talltal from the shutter release to the completion of the final exposure. Is long. In addition, to match the movement of various sports,
Medium speed (2 seconds), high speed (1
Second) and ultra-high speed (3 seconds).

[0004]

[Problems to be Solved by the Invention] However, the movement of playing sports by individual people is different. Then, for example, the swing time from the take-back to the finish of golf was analyzed with a professional golfer, an amateur male, and an amateur female. As shown in FIGS. 33 to 35,
Swing time of 1.2 seconds to 1.7 for professional golfers
The variation is within the range up to the second, whereas it is 0.9 to 2.6 seconds for amateur men and 1.3 to 2.6 seconds for amateur women. Turned out to be. Therefore, when shooting a person who takes a swing motion for 2 seconds or more, even if the person shoots at the medium speed, which is the longest continuous shooting time, the series of motions from the beginning to the end of exercise cannot be captured within the continuous shooting time. Therefore, it takes a continuous shot to shoot from the top to the finish by omitting the takeback or omitting the finish, which makes the photographer dissatisfied.

Further, when the photographer selects one of the three types of continuous shooting time, the exposure interval is uniquely determined. For this reason, even if you take a picture of how long it is appropriate to capture the movement of the subject and when the shutter release timing is performed, important points in the movement of each sport, such as golf An image at the moment of impact during a swing may not be obtained in some cases, and such a continuous photograph lacks power.

Further, in analyzing the movement of the sport, it is preferable that the state of the starting point, for example, the state of holding the club in golf is recorded at the beginning of the continuous photograph for the analysis. However, the photographer cannot grasp the timing at which the subject shifts to takeback after holding the club, so the shutter release timing is inevitably delayed, and the photographer cannot hold the club. . Therefore, if you release the shutter while holding the club, continuous shooting may be completed by the time you move to takeback, or the subject may temporarily stop swinging. It will be a failure shooting.

On the contrary, not only the movement of the sport but also the result thereof, for example, the whereabouts of the ball by the continuous golf swing, that is, whether it is the OB or the fairway, and whether it is a fault in the tennis service, , In baseball, there is a case of recording a home run. However, if such recording is performed, naturally, it is inevitable to perform shooting that wastes the film only by continuous shooting.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and its object is to take a continuous photograph from the early stage to the final stage of motion even for a slow-moving subject. An object of the present invention is to provide a continuous shooting camera capable of performing continuous shooting at a timing desired by a photographer.

[0009]

In the continuous shooting camera of the present invention, the external selection means for selectively selecting the one-shot shooting mode and the continuous shooting mode and the axis line passing through substantially the center of each frame are provided. A plurality of shutter apertures and a plurality of photographing lenses respectively arranged, a shutter disk that sequentially passes through a slit provided across the plurality of shutter apertures, and a plurality of the slits when photographing in the continuous photographing mode. The shutter disc is continuously rotated so as to sequentially traverse the shutter aperture of, and at the time of photographing in the one-shot photographing mode, the shutter disc is rotated by a predetermined angle so that the slit traverses one shutter aperture. And a rotation means for stopping it later.

[0010]

When the external selection means is selected and operated in the continuous shooting mode, the rotating means continuously rotates the shutter disk so that the slit sequentially crosses the plurality of shutter openings.
Time-sequential images are sequentially exposed on a plurality of frames on the screen. Further, during shooting in the one-shot shooting mode, the rotating means rotates / stops the shutter disk by a predetermined angle, and the slit crosses one shutter opening during one frame to one frame.
The image is exposed. Therefore, in shooting in the one-shot shooting mode, shooting can be performed at the timing desired by the photographer, and since film winding is not involved, continuous shutter release can be performed quickly. Further, by alternately performing shooting in the one-shot shooting mode and the continuous shooting mode, a series of movements of subjects playing various sports can be contained within the screen.

By the way, in the photographing method in which the photographing is alternately performed in the one-shot photographing mode and the continuous photographing mode, it is necessary to enable the release operation quickly and accurately. Therefore, in the inventions according to claims 2 and 3,
Two release buttons were provided, one for shooting in the one-shot shooting mode and the other for shooting in the continuous shooting mode. In this case, it is desirable to place the two release buttons side by side so that they can be easily pressed alternately. Also, instead of this, shooting in the one-shot shooting mode by half-pressing one release button,
When the continuous shooting mode can be performed by full-press operation, mode switching and shooting in that mode can be performed quickly, and a shutter chance is not missed.

Further, in the case of performing continuous shooting after performing one-shot shooting, if continuous shooting is performed without determining the number of frames in continuous shooting, continuous shooting may occur during the movement of the subject due to the release timing. There is a risk that shooting will end and shooting will end in failure. Therefore, in the invention according to claim 4, there is provided a one-shot photographing counter for counting the number of times the image is exposed on a frame obtained by dividing one screen into a plurality of frames, and a display means for externally displaying the count value of the one-shot photographing counter. It is equipped.

According to the fifth aspect of the present invention, the continuous shooting camera further comprises an external selection means for selectively selecting one-shot shooting mode, continuous shooting mode, and continuous shooting and one-shot shooting mode. According to this, by selecting the continuous shooting mode and the one-shot shooting mode, it is possible to shoot only one frame of the result of the continuous motion on the last frame after the continuous motion is photographed.

Further, in such a continuous shooting camera, by providing the shutter movement display means for displaying the movement of the shutter disk, it is possible to prevent the shutter shake occurring during continuous photographing. As the film winding means, in order to quickly prepare for the next shooting, the film winding is performed when the rotation of the shutter disk that exposes the image on the last frame is stopped by the rotation means. Is desirable. As a means for rotating the shutter disc,
It is desirable to use a stepping motor that can easily control the rotation angle.

Such a shutter unit 22 is shown in FIG.
As shown in, the dark box 8 formed in the inner view of the continuous shooting camera 11
It is attached to the front of 0. In the dark box 80, 16 exposure frames 81 are formed for each optical axis of the taking lenses 13a to 13p, which are divided into two upper and lower rows and eight left and right rows by a partition wall. Configure the screen. The exposure frame 81 is
For example, it has a size of about 10 mm long × 8.3 mm wide,
The circumference is cut a little when printing, so one screen is vertically 2
The size is 0 x 36 mm in width.

As shown in FIG. 10, a cartridge loading chamber 84 and a film winding chamber 85 are arranged on the left and right of the dark box 80. The photo film 86 is wound up by rotating a spool 87 provided in the film winding chamber 85, and pulled out from a cartridge 88 loaded in a cartridge loading chamber 84. A motor 87a for winding the film is built in the spool 87, and the spool 87 is rotated through an internal gear when the film is wound up, and when the film is rewound, the spool 89 is loaded into the cartridge loading chamber 84 through the gear 89 and the film feeding mechanism 90. The rewinding fork 91 provided inside is rotated in the opposite direction.

The film perforation 86a includes:
The sprocket 92 is engaged and rotated by feeding the film. A through-hole slit plate 93 having a large number of through-hole slits radially provided is coaxially fixed to the sprocket 92. The through hole slit plate 93 is photoelectrically detected by the PI sensor 94. The PI sensor 94 sends a pulse every time the through-hole slit passes.

The circuit configuration of the continuous shooting camera 11 is shown in FIG. The shutter unit 22 and the feeding of the photo film are C
It is controlled by the PU 100, and these sequences are written in the program ROM 101. For the photo film feeding sequence, turn on the power switch 17.
After that, when the opening / closing signal 102 of the back cover 21 is obtained, the drive signal of the motor 87a is sent to the motor driver 103. After that, when the PI sensor 94 obtains the number of through-hole slits corresponding to two screens, a stop signal for stopping the driving of the motor 87a is sent to the motor driver 103.
The CPU 100 has a built-in driver for driving the liquid crystal display unit 18, and controls the liquid crystal display unit 18 via the driver so as to display the number of shots every time the film is wound. The liquid crystal display unit 18 has a built-in display unit for displaying the number of shots and the number of shots of one-shot shooting.

The motor drivers 104 and 105 are CPUs.
Receiving the control signal and the clock pulse from 100, the drive pulse is supplied to the stepping motors 49 and 50, respectively. As is well known, since the stepping motors 49 and 50 rotate in proportion to the number of drive pulses supplied, the rotation angle can be determined by the number of drive pulses, and the drive pulse can be changed to a frequency to generate a pulse. The speed of rotation can be controlled by changing the interval.

The number of drive pulses supplied from the motor drivers 104 and 105 to the stepping motors 49 and 50 is counted by a counter incorporated in the motor drivers 104 and 105. Then, the CPU 100 monitors the count of the counter and sends a control signal to the motor drivers 104 and 105 each time the count value reaches a predetermined value. The motor drivers 104 and 105 change the frequency and the number of poles of the drive pulse supplied to the stepping motors 49 and 50 according to the control signal, and control the speed and the rotation direction of the stepping motors 49 and 50. The continuous shooting time setting circuit 106 sends a mode signal corresponding to the setting of the continuous shooting time changing slide switch 19 to the CPU 100. The count value is updated and written in the one-shot shooting counter 99 each time the CPU 100 performs one-shot shooting. CPU10
0 is used to read the count value of the counter 99 as necessary, determine the exposure interval when performing continuous shooting after performing one-shot shooting, and display the updated count value. The display unit 18 is controlled.

The PI sensors 69 and 70 are the shutter disc 3
When detecting 2 rotations of 2 to 37, the CPU 100 outputs a detection signal.
Send to The CPU 100 monitors the detection signals from the PI sensors 69 and 70, and controls the driving of the stepping motors 49 and 50 to stop when the detection signals are obtained.
At this time, the counters of the motor drivers 104 and 105 are reset, and then the film winding process is performed. The film winding is performed at the same time when the driving of the stepping motor 50 for photographing the last frame 75h is stopped.

The photographing sequence is as shown in FIG.
Different in continuous shooting mode and one-shot shooting mode.
When the continuous shooting mode is selected first, 2 screens 1
The stepping motors 49 and 50 are alternately driven every one rotation of the shutter disks 32 to 39 in order to expose time-series images on six frames. That is, first, only the stepping motor 49 is driven, and the driving of the stepping motor 49 is stopped when the count of the counter reaches one rotation of the shutter disks 32, 33, 36, 37. During this period, the switching shield plate 57 acts to sequentially expose only the four frames 74a to 74d.

Next, the stepping motor 50 is driven almost at the same time as the stepping motor 49 is stopped, and the count of the counter is 1 of the shutter disks 34, 35, 38, 39.
The driving of the stepping motor 50 is stopped when the rotation amount is reached. During this period, the action of the switching shield plate 58 causes 4
The tops 75a to 75d are sequentially exposed. Further, substantially simultaneously with the stop of the stepping motor 50 described above, only the stepping motor 49 is driven, and when the detection signal is obtained from the PI sensor 69, the driving of the stepping motor 49 is stopped. During this period, the four shields 74e to 74h are exposed by the action of the switching shield plate 57. Finally, the stepping motor 50 is driven substantially at the same time as the stepping motor 49 is stopped, and the driving of the stepping motor 50 is stopped when a detection signal is obtained from the PI sensor 70. During this period, the exposure of the four frames 75e to 75h is sequentially performed by the action of the switching shield plate 58.

The driving of the stepping motors 49 and 50 is
The pulse interval is controlled stepwise so as to rotate each exposure time at a high speed only at the moment of exposure so that each exposure time becomes 1/250 seconds, for example. That is, each slit 32a-39
Since the rotational positions of the shutter discs 32 to 39 when a crosses the aperture openings 31a to 31p are known, immediately before each exposure, the motor drivers 104 and 105 drive pulses whose frequencies gradually increase. That is, as shown in FIG. 13, a drive pulse whose pulse interval is gradually shortened to T1, T2, and T3 is sent to the stepping motors 49 and 50 to accelerate the rotation of the stepping motors 49 and 50, and immediately after the exposure, the pulse is pulsed. A drive pulse whose intervals gradually increase to T3, T2, T1 is sent to the stepping motors 49, 50,
The rotations of the stepping motors 49 and 50 are decelerated. Then, each exposure interval is made longer than the exposure time by giving a drive pulse having a relatively long pulse interval.

As shown in Table 1, the exposure interval varies depending on the continuous shooting time, and differs for each frame for each continuous shooting time. Then, for example, when the continuous shooting time is set to a low speed, as shown in FIG.
~ 39 rotates to expose time-series images in 16 frames.

[0045]

[Table 1]

When shooting all 16 frames in the one-shot shooting mode, the stepping motor 4 is released for each release.
9 is driven by a predetermined angle to perform exposure from the first frame to the fourth frame. Next, the exposure from the fifth frame to the eighth frame is performed by driving the stepping motor 50 by a predetermined angle for each release. Further, the exposure from the 9th frame to the 12th frame is performed by driving the stepping motor 49 by a predetermined angle, and the exposure from the 13th frame to the 16th frame is performed by driving the stepping motor 50 by a predetermined angle. . Even in this mode, the pulse interval is set stepwise so that each exposure time is, for example, 1/250 seconds. Further, in order to stop the stepping motors 49 and 50 at a predetermined angle, the shutter disks 32 to 37 stop at a position where the angle between the next aperture opening and the slit becomes constant in order to make the time lag for each release constant. To be controlled.

When the continuous shooting mode is selected after shooting in the one-shot shooting mode, the count value of the one-shot shooting counter 99 is read to determine the exposure interval for the remaining number of frames. This exposure interval is determined to be the same as the exposure interval defined for each frame shown in Table 1 above. For example, when the continuous shooting time is set to a low speed, it becomes as shown in Table 2.

When the continuous shooting mode is selected after shooting in the one-shot shooting mode, the exposure interval may be set to be equal to the remaining number of frames. In this case, the exposure interval is determined by the following formula.

[0050]

[Equation 1]

In this case, for example, when the continuous shooting time is selected to be low, the exposure interval for each frame is as shown in Table 3.

[0052]

[Table 3]

Next, the operation of the continuous shooting camera having the above structure will be described. The initial state of the shutter unit 22 is, as shown in FIG. 15, the shutter disks 32, 36, 3
The slits 32a, 36a, 34a, 38a of 4, 38 are located at the left horizontal position across the shafts 44, 40, 46, 42, and the slits 33a, 37a, 35a of the shutter discs 33, 37, 35, 39. , 39a are axes 41, 4
It is in a state of being positioned at the horizontal position on the right side with 5, 43, 47 interposed therebetween. The aperture openings 31a to 31p are shielded by the shutter discs 32 to 39. Also,
The slit gears 65 and 66 of the shutter mechanism 23 and the slit gears 67 and 68 of the shutter mechanism 24 are in a state in which the slits 65a, 66a, 67a and 68a overlap at a position above a vertical line passing through the rotation axis. .

In the initial state of the switching shield plate 57, as shown in FIG. 8, the openings 57a to 57d are the aperture openings 31a to 31.
d is exposed and the openings 51e to 51h are the diaphragm openings 31i to 3h.
1l is shielded. Further, in the initial state of the switching shield plate 58, the openings 58a to 58d shield the diaphragm openings 31e to 31h, and the openings 58e to 58d form the diaphragm openings 31m to 31p.
Is exposed.

With the continuous shooting time changing slide switch 19 set to a low speed, the continuous shooting release button 16 is operated at the same time when the subject takes back, as shown in FIG. As a result, the stepping motor 49 starts driving, and as shown in FIG. 17, the motor gear 51 rotates counterclockwise, and the shutter discs 32, 3 via the two-step gear 55.
3 simultaneously rotates in the clockwise direction, and the shutter disks 34 and 35 simultaneously rotate in the counterclockwise direction. The rotation at this time controls the driving of the stepping motor 49 so that the exposure interval is different from the exposure time. Since the openings 57a to 57d of the switching shield plate 57 expose the aperture openings 31a to 31d, the slit 32a of the shutter disk 32 crosses the aperture opening 31a 200 ms after the release, and the first frame 74a is exposed. Exposure is performed.

At this time, the opening 51e of the switching shield plate 57
Since ~ 51h shields the diaphragm openings 31i-31l, exposure is not performed by these diaphragm openings 31i-31l. Further, as shown in FIG. 18, since the crank gear 59 rotates counterclockwise, the switching shield plate 58
Moves to the left and slightly exposes the aperture openings 31e to 31h at the openings 58a to 58d, but since the stepping motor 50 on the shutter mechanism 24 side is not driven, the shutter disks 34, 35, 38, 39. Due to its own shielding, the aperture openings 31e to 31h and the aperture openings 31m to 31p are not exposed. Further, at this time, the gear with slit 66 is in a state of being rotated to a position of a half angle with respect to the angle of rotation of the shutter discs 32, 33, 36, 37. Further, the gear 65 with the slit is 1.5 with respect to the rotation angle of the shutter disks 32, 33, 36 and 37.
It has been rotated to the double angle position.

100 ms after the first exposure, the slit 32a crosses the diaphragm opening 31b and the frame 74b.
The second exposure, and 100 ms after this, the slit 33a of the shutter disk 33 traverses the aperture opening 31c and the third exposure on the top 74c.
After ms, the slit 33a crosses the aperture opening 31d to perform the fourth exposure on the frame 74d.

After that, the shutter disc 3 counts by the counter.
When one rotation of 2, 33, 36 and 37 is reached,
As shown in 9, the driving of the stepping motor 49 is stopped. At this time, the gear with slit 66 is in a state of a half rotation from the initial position, and the gear with slit 65 is in a state of rotating 1.5 times from the initial position. Further, as shown in FIG. 20, since the crank gear 59 has rotated 1.5 times from the initial position, the switching shield plate 5
8 of the apertures 58a to 58d completely expose the aperture openings 31e to 31h, and the apertures 58e to 58h of the aperture openings 31e to 31h.
1p is completely shielded.

After the stepping motor 49 is stopped, the stepping motor 50 is driven substantially at the same time. As a result, as shown in FIG. 21, the motor gear 52
Rotates counterclockwise, the shutter disks 34, 35 rotate clockwise through the two-stage gear 56, and the shutter disks 38, 35
39 rotates counterclockwise at the same time. The drive of the stepping motor 50 is controlled so that the rotation at this time also has an exposure interval different from the exposure time. And
The openings 58a to 58d of the switching shield plate 58 are the aperture openings 31.
e-31h is exposed, so 10th from the 4th exposure
After 0 ms, the slit 34a of the shutter disk 34 crosses the aperture opening 31e, and the frame 75a is exposed for the fifth time.

100 ms after the fifth exposure, the slit 34a crosses the aperture opening 31f and crosses the frame 74b.
The sixth exposure, and 100 ms after this, the slit 33a of the shutter disk 33 crosses the aperture opening 31c and the seventh exposure is performed on the top 74c.
After ms, the slit 33a crosses the aperture opening 31d and exposes the top 74d for the eighth time.

After that, the count of the counter is counted by the shutter disk 3.
When one rotation of 4, 35, 38 and 39 is reached,
As shown in 2, the driving of the stepping motor 50 is stopped. At this time, the gear with slit 66 is in a state of a half rotation from the initial position, and the gear with slit 65 is in a state of rotating 1.5 times from the initial position. Further, as shown in FIG. 23, since the crank gear 60 rotates 1.5 times from the initial position, the switching shield plate 5
7 apertures 57e to 57h completely expose the aperture openings 31i to 31l, and apertures 57a to 57d are aperture openings 31a to 3l.
1d is completely shielded.

The driving of the stepping motor 49 is started at substantially the same time as the stepping motor 50 is stopped. As a result, 100 ms after the eighth exposure, the slit 36a of the shutter disk 36 crosses the diaphragm opening 31i, and the openings 57e to 57h of the switching shield 57 are diaphragm openings 31i to 31l.
Therefore, the frame 74e is exposed for the ninth time.

100 ms after the ninth exposure, the slit 36a crosses the diaphragm opening 31j and the frame 74f.
10th exposure, and 100 ms later, the slit 37a of the shutter disk 37 traverses the aperture opening 31k and the eleventh exposure to the frame 74g.
After 0 ms, the slit 37a crosses the aperture opening 31l to perform the twelfth exposure on the frame 74h. After that, when the shutter disks 32, 33, 36, 37 reach two rotations, the slit gear 65 rotates three times and the slit gear 6
Since 6 rotates once, the slits 65a, 66 of each other are
a just overlaps at the initial position, and a detection signal is obtained from the PI sensor 69. As a result, the driving of the stepping motor 49 is stopped.

At this time, since the crank gear 59 has rotated three times from the initial position, the opening 58e of the switching shield plate 58 is formed.
.About.58h completely expose the diaphragm openings 31m to 31p, and the openings 58a to 58d completely shield the diaphragm openings 31e to 31h.

The stepping motor 50 is driven substantially at the same time as the stepping motor 49 is stopped, and the switching shield plate 58 is driven.
Since the apertures 58e to 58h of the shutter expose the diaphragm openings 31m to 31p, the slit 38a of the shutter disk 38 crosses the diaphragm opening 31m 100 ms after the twelfth exposure, and the frame 75e is exposed the thirteenth time.

After the thirteenth exposure is performed, 1
After 00 ms, the slit 38a crosses the aperture opening 31n, and the frame 75f is exposed for the 14th time.
After s, the slit 39a of the shutter disk 39 is closed by the aperture opening 3
The frame 74g is traversed 1o and the frame 74g is exposed for the 15th time, and 300 ms later, the slit 39a opens the aperture 31p.
The 16th exposure is performed on the frame 74h. afterwards,
When the shutter disks 34, 35, 38, 39 reach two rotations, the slit gear 68 makes three rotations and the slit gear 67 makes one rotation.
7a and 68a overlap exactly at the initial position, and the PI sensor 70
The detection signal is obtained from As a result, the driving of the stepping motor 50 is stopped, and the crank gear 60 is rotated three times from the initial position, so that the openings 57a to 57d of the switching shield plate 57 completely expose the aperture openings 31a to 31d. Thus, the shutter unit 22 returns to the initial state shown in FIG.

When the detection signals are obtained from the PI sensors 69 and 70, the CPU 100 drives the film feeding motor 87a to wind up the photographic film 86,
The number of passing slits obtained from the PI sensor 94 is counted, and when the count value for two screens is reached, the driving of the motor 87a is stopped. As a result, two new screens are set in each exposure frame 81.

Next, the one-shot shooting mode will be described. Shooting in the one-shot shooting mode is selected by operating the one-shot release button 15.
In this mode, the frames are exposed in the same order as in the continuous shooting mode, and the images at the time of release are exposed for each frame. Therefore, the stepping motors 49 and 50 are driven at predetermined angles to expose the images for each release one frame at a time, which is suitable for photographing the posture of the golf swing at the beginning, for example.

For example, when shooting 16 frames in the one-shot shooting mode, first, the stepping motor 49 is driven by a predetermined angle in the first release. As a result, the slit 32a crosses the aperture opening 31a and the frame 74a of the screen 74 is exposed. The stop control of the stepping motor 49 at this time is, as shown in FIG.
The shutter disc 32 is controlled to stop at a position before the aperture opening 31b by the angle θ so that the angle θ is the same as the angle θ from the initial state to the exposure opening 31a. In this way, the time lag becomes constant by fixing the stop position after each exposure.

Thereafter, the stepping motor 49 is used for the fourth release, the stepping motor 50 is used for the fifth to eighth releases, the stepping motor 49 is used for the ninth to twelfth releases, and 13 to 16 are released.
In the release up to the first release, the stepping motor 50 is driven by a predetermined angle to display images for each release in each frame 74b-7.
4h and 75a-75h are exposed respectively.

Next, a case where continuous shooting is performed after one-shot shooting will be described. In FIG. 16, after the first two frames are shot in the one-shot shooting, the remaining 1
The case where continuous shooting is performed on four frames is shown. When one-shot shooting is performed, the number of shootings is counted by the one-shot shooting counter 99. This count is used when determining the exposure interval for the remaining frames, and therefore the exposure interval for each frame with respect to the number of remaining frames is determined to be the same as the exposure interval for each frame in the continuous shooting mode. . For example, when the continuous shooting time is selected to be low speed, as shown in FIG. 25, each exposure is performed by rotating the shutter disk.

The count value of the one-shot photographing counter 99 is displayed on the liquid crystal display unit 18 every time it is updated. This display is a circle display on the liquid crystal display unit 18,
The number of times of one-shot shooting is displayed according to the number of illuminated fan-shaped areas obtained by dividing a circle into 16. As an alternative to this, 16 rectangular frames may be displayed on the liquid crystal display unit 18, and the number of times of one-shot photography may be displayed by the number of these frames turned on.

When a load is applied to the motor 87a when the film for two screens is wound, the motor 87a is detected to detect the load, and the photographic film 86 is completely rewound to remove the exposed photographic film 86. Store in Patrone 88. When the film rewinding is completed, the case back 21 is opened and the cartridge 88 is taken out and submitted to the photo lab. At the photo lab, the conventional processing is performed, and the developed photo film 86 is printed for each screen, and 89 × 158.
A printed photograph with a high-definition ratio of mm is produced. Then, by arranging the obtained two print photographs side by side, it is possible to observe 16 still images in which the movement of the subject has stopped at each moment.

In the embodiment described above, the two release buttons 15 and 16 are provided as means for shooting in the one-shot shooting mode and the continuous shooting mode.
However, the present invention is not limited to this, and for example, one release button may be provided to allow half-press operation for shooting in the one-shot shooting mode and full-press operation for shooting in the continuous shooting mode. In this case, since the half-push position is located at the passage point of the full-push operation, it is necessary to monitor the time when the half-push operation is performed and perform control to determine whether the half-push operation is performed.
According to this, continuous shooting can be performed quickly by simply pushing in the finger after performing the one-shot shooting, so that a shutter chance is not missed.

Further, one release button and an external changeover switch may be provided so that photographing in the one-shot photographing mode and the continuous photographing mode can be performed by the switching operation of the external changeover switch. Further, one release button and one shift button are provided, and shooting in the one-shot shooting mode is performed with the release button, and shooting in the continuous shooting mode is performed by operating the release button while pressing the shift button. You may do it. In this case, it is preferable that the holding device is arranged so that the index finger of the right hand and the shift button may be applied to the finger of the left hand when holding.

In the continuous shooting camera of the above-described embodiment, when the continuous shooting mode is first selected, time-sequential images are automatically exposed on all of the 16 frames on 2 screens. After continuous shooting for frames, one-shot shooting is not possible for the remaining frames. However, by providing an external setting member for setting the number of frames for continuous shooting in advance, it is possible to perform continuous shooting for a plurality of frames out of 16 frames of two screens and then perform one-shot shooting for the remaining frames. Become.

First, continuous shooting is performed for 15 frames,
A mode for performing one-shot shooting may be provided for the remaining one frame. The continuous shooting camera 120 shown in FIG. 26 has, as external selection means, one shutter button 121,
One-shot shooting mode selection button (hereinafter referred to as “F selection button”) 122, continuous shooting mode selection button (hereinafter referred to as “C selection button”) 123, and continuous shooting + one-shot shooting mode selection button. (Hereafter, "F / C
It is called a "select button". ) 124 are provided on the upper surface, respectively. These buttons 122 to 124 are selected by operating them before the start of shooting.

When the F selection button 122 is pressed before shooting, the one-shot shooting mode is selected, and the image for each subsequent release operation of the shutter button 121 is exposed frame by frame, and shooting for 16 frames is completed. After that, the film is wound up. The film winding is performed at the same time when the driving of the stepping motor 50 for photographing the last frame 75h is stopped.

When the C selection button 123 is pressed, the continuous shooting mode is selected, and the shutter button 12 after that is selected.
In synchronism with the release operation of 1, the time-series image is sequentially exposed on 16 frames obtained by dividing the two screens, and the film is wound up after the exposure of 16 frames is completed.

When the F / C selection button 123 is pressed, the continuous shooting + one-shot shooting mode is selected, and 15 of the 16 frames obtained by dividing the two screens are linked with the subsequent shutter button 121 release operation. After time-sequential images are sequentially exposed on the frames, the frames are temporarily stopped. afterwards,
Releasing the shutter button 121 releases the remaining 1
Make one-shot shooting for a frame. Then, after the last one-shot shooting is performed, film winding is performed.

As shown in FIG. 28, the liquid crystal display section 125 provided on the upper surface of the continuous shooting camera 120 has a film count display section 126 for displaying the film count by the segment electrode structure and a film presence mark display section 12 as shown in FIG.
7. Mode selection display unit 128 and shooting state display unit 1
29 and the like are provided.

In the mode selection display section 128, a display showing the currently selected shooting mode, for example, a character segment of "F shooting", "C shooting", and "F / C shooting" is displayed. It In the shooting state display section 129,
16 rectangular rectangles 130 in total, 2 rows up and down, 8 rows left and right
Is displayed, and the display of the 16 rectangular segments 130 is changed according to each shooting mode to indicate the shooting state.

When the one-shot shooting mode is selected, as shown in FIG. 29, all of the rectangular segments 130 are turned off, and one rectangular segment 130 is provided according to the count of the one-shot shooting counter 99 for each release operation. It lights up. The lights are lit in order from the upper left to the right, and from the lower left to the right from the ninth frame of shooting. Then, after the film winding is completed after the exposure of the 16th frame is completed, all the rectangular segments 130 are turned off.

When the continuous shooting mode is selected, as shown in FIG. 30, the rectangular segments 130 are lit one by one at the same interval as the exposure interval corresponding to the continuous shooting time selected by the continuous shooting time changing slide switch 19. I will do it. Then, after the film winding is completed, the entire rectangular segment 13
0 goes out.

When the continuous shooting + one-shot shooting mode is selected, as shown in FIG.
The individual pieces are turned off, and the last one rectangular segment 130a is in a blinking state. Then, as described above, the rectangular segments 130 are lit one by one at the same interval as the exposure interval corresponding to the continuous shooting time selected by the continuous shooting time changing slide switch 19 by the first shutter release.

When the continuous shooting is completed, the 15 rectangular segments 130 are lit, and the remaining 1 rectangular segment 130a remains blinking. This blinking makes the photographer recognize that one shot has been taken once. After that, by performing the second shutter release, the remaining one rectangular segment 130a is turned on. Then, after the film winding is completed, all the rectangular segments 130 are turned off.

The slide switch 19 for changing the continuous shooting time of the continuous shooting camera 120 is provided on the back side as shown in FIG. A shutter operation display lamp 132 is provided next to the eyepiece finder unit 131. The shutter operation indicator lamp 132 is used for the shutter disk 3

This is performed under the control of the CPU 100 described with reference to FIG. The shutter disc 3 can be visually recognized in the field of view while looking through the eyepiece finder 131.
It is possible to prevent the shutter shake that occurs when the camera 120 is moved during the rotation of 2 to 39. 26 to 32, the same reference numerals are given to the same functional members as those in the embodiment described in FIGS. 1 to 25, and detailed description thereof is omitted.

In the above embodiment, the one-shot shooting mode is selected after the continuous shooting mode to expose all the frames obtained by dividing one screen into a plurality of frames. However, the present invention is not limited to this. An image may be exposed on all frames by alternately selecting the photographing mode and the one-shot photographing mode. For example, in sequential shooting mode, three frames are sequentially exposed, and then in one shot mode, one frame is exposed. Then, in continuous shooting mode, the remaining frames are sequentially exposed to one image. The image is exposed on all the frames that make up. In this case, when the continuous shooting mode is selected, an external setting means for presetting the number of images to be exposed on a frame obtained by dividing one screen into a plurality of frames, and an image at the frame obtained by dividing one screen into a plurality of images are displayed. It is necessary to include a photographing counter that counts the number of times of exposure and a display unit that externally displays the count value of the photographing counter. The display means is not always necessary.

In each of the above embodiments, eight shutter discs are alternately rotated by two stepping motors, and two screens are formed across each of the 16 shutter openings by the slits provided in the shutter disc. A continuous shooting camera of the type that exposes 16 frames of images has a one-shot shooting mode. However, the present invention is not limited to this, and a continuous shooting camera that can have a one-shot shooting mode is, for example, a special one. As proposed in Kaihei 4-269729, two shutter discs are rotated by a stepping motor, and eight shutter openings horizontally aligned by a slit provided in each of the shutter discs are sequentially arranged. Type that exposes 8 frames of images on 2 screens
As proposed in Japanese Unexamined Patent Publication No. 2-1051232, one shutter disk is rotated by a stepping motor, and one slit provided in the shutter disk allows vertical and horizontal movement.
A type in which four frames of images are exposed on one screen across each of the four shutter openings arranged in rows may be used.

[0090]

As described above, according to the present invention, in the one-shot photographing mode, the photographing can be performed at the timing desired by the photographer, and since the film is not wound, the continuous shutter is used. The quick release allows you to reliably capture the most important points in a series of movements in various sports. Also, by alternately shooting in the one-shot shooting mode and the continuous shooting mode, continuous shooting can be performed at the exposure interval intended by the photographer, no matter how slow the movement of the subject playing various sports is. A series of movements can be reliably contained within the screen. For example, if you take a one-shot shot of the posture in which you first hold the club among the golf swing movements, and then perform continuous shooting from the time you take back, you will hold the club at the time of the one-shot shot on the screen. The posture image is recorded as a series of images including the takeback, top, downswing, impact, and finish at the time of continuous shooting, so that the sports motion can be accurately analyzed.

According to the second and third aspects of the present invention, the mode switching between the one-shot photography and the continuous photography and the photography in that mode can be performed quickly, so that a photo opportunity is not missed. According to the invention described in claim 4, since the one-shot shooting counter and the display means for externally displaying the count value of the one-shot shooting counter are provided, when the continuous shooting is performed after the one-shot shooting, Since the number of frames at the time of continuous shooting can be determined and shooting can be performed, the release timing at the time of continuous shooting can be grasped, and failure shooting can be prevented, and the waste of the photo film can be prevented.

According to the fifth aspect of the present invention, since the continuous shooting mode and the one-shot shooting mode are provided, by shooting the result after shooting the continuous operation, for example, the analysis of the form can be performed quickly from the result status. You can recoil.
Moreover, since this result is recorded in the last frame in one screen where continuous shooting is performed, analysis can be performed smoothly and the people who have been photographed are also entertaining, and as a result, the degree of use of the continuous shooting camera is increased. Will increase.

According to the sixth aspect of the invention, since the stepping motor and the control means having a circuit configuration are used, for example, the rotation of the shutter disk and the control of the rotation angle thereof are performed by a mechanical mechanism. The number of parts can be reduced and miniaturization can be achieved compared to the above. According to the invention described in claim 7, by providing the shutter movement display means for displaying the movement of the shutter disk, it is possible to prevent the shutter shake which is likely to occur during continuous photographing, and the film winding means is the last means by the rotating means. Since the film is wound up when the rotation of the shutter disk that exposes the image on the frame is stopped, there is an advantage that the next shooting preparation can be performed quickly.
