Abstract

PURPOSE:To photograph the consecutive photographing images which are arranged in a line and to reproduce a consecutively photographed scene in which temporal continuity is easily recognized by rotating two or more shutter plates on both sides which interpose exposing apertures arrayed in a line along the feeding direction of a film. CONSTITUTION:When a slit 15a moves clockwise from an origin position P0 shown in figure and passes a 1st exposing position P1 by the rotation of the shutter plate 10, the exposing aperture 6a is opened and closed. When the shutter plate 10 continues to rotate and the slit 15b passes a 2nd exposing position P2, the exposing aperture 6b is opened and closed. Every time the slits 15b and 15a successively pass 3rd and 4th exposing positions P3 and P4, the exposing apertures 6c and 6d are successively opened and closed. When the shutter plate 10 starts to rotate clockwise, the shutter plate 11 rotates counterclockwise by meshing with gears 10a and 11a. After the slit 15a passes the 4th exposing position P4, the slit 16a of the shutter plate 11 rotates from an origin position Q0 to a 5th exposing position Q5, and when it passes the position Q5, the exposing aperture 6e is opened and closed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a continuous shooting shutter device that sequentially performs exposure at short time intervals by one release operation.

[Prior art] If a moving subject is photographed sequentially with a time lag, it is possible to obtain a photographic image in which the movement stops at each photographing moment. It can be observed as an image, which is very convenient.

This kind of continuous shooting function is achieved with motor-driven cameras by taking a picture each time the film is wound one frame at a time at high speed, but this is limited to about four frames per second, and there is a delay between winding the film and taking pictures. The drawback is that a mechanism for synchronizing is required, making the structure complex and increasing costs. Furthermore, since several frames are taken in one continuous shooting, the amount of film consumed increases, and there is also the problem that it becomes impossible to take many quick shots with one piece of film.

Against this background, as seen in Japanese Patent Publication No. 41-13352 and Japanese Patent Application Laid-Open No. 2-105132, a quick-shooting camera has been proposed that sequentially takes pictures through multiple exposure apertures with a single release operation. ing. In the camera described in the former publication, shutter blades are provided in each of a plurality of exposure apertures, and these shutter blades are mechanically scanned to sequentially take pictures. In addition, the camera described in the latter publication has four exposure apertures through which the respective snapshot screens are arranged in a ``tag'' shape, and all it takes is one rotation of a single rotary shutter plate. Now, a four-frame continuous shot screen that is time-shifted is taken.

[Problem to be solved by the invention]

However, with shutter blades provided for each of multiple exposure apertures, although it is possible to take many snapshots in one snapshot, it requires a shutter blade for each exposure aperture, so parts The number of points increases and cost amplifier cannot be avoided. In addition, in the case where a single shirt plate is rotated and multiple snapshots are taken at positions equidistant from the center of rotation, it is difficult to increase the number of snapshots taken in one shot. Not only “Ten”
The disadvantage is that the chronological order of the snapshots is difficult to discern because the printed photographs are arranged in a letter-shaped arrangement.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and its purpose is to take pictures by arranging a plurality of quick-shot screens in a line along the film feeding direction.
Moreover, it is an object of the present invention to provide a shutter device for continuous shooting which has a simple structure and a small number of parts.

[Means for Solving the Problems] The shutter device of the present invention has a plurality of exposure apertures arranged in a straight line along the film feeding direction, and each rotation center is arranged alternately on the opposite side with respect to the arrangement of the exposure apertures. It is composed of two or more disc-shaped shirt flap plates set so as to have the same shape, and an opening formed in each of these shirt flap plates.

Furthermore, a plurality of openings are formed in at least one of the shutter plates at positions different in distance from the rotation center thereof, and each opening performs exposure across a predetermined exposure opening. In order to efficiently drive a plurality of shirt starter plates, gears are formed on the shirt starter plates so that they mesh with each other, and one of the gears is driven by a motor to rotate the shirt starter plates all at once. At the moment of exposure, the motor is driven at high speed via the motor control means to obtain a high shutter speed without narrowing the interval between each exposure operation during continuous shooting.

[Effect]

When the shirt shirt plates rotate, each of the openings formed in each shirt shirt plate is exposed to light across a predetermined position of the plurality of exposure openings. By providing a plurality of apertures at different distances from the rotation center of the shirt plate, the exposure apertures that are opened and closed by these openings can be placed at different distances from the rotation center of the shirt plate. By arranging the images in a straight line, it is possible to take continuous shots over time by arranging them in a line.

When rotating the shutter plate to perform multiple exposures, if the rotation speed of the shutter plate is increased, continuous shooting will end in a short period of time, making it impossible to photograph the entire movement from the beginning to the end. On the other hand, if the rotation speed of the shutter plate is slowed down (this will lengthen the shutter speed during each exposure, which is not only unsuitable for instantaneous photography but also may lead to overexposure.

Therefore, the shutter plate is driven by a motor, and the motor control means increases the rotational speed of the motor only at the moment of exposure.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiments.

[Example] In FIGS. 1 to 3 showing a continuous shooting camera using the present invention, there are eight photographic lenses 3 on the front surface of a camera body 2.
The lenses a to 3h are arranged and attached horizontally, and the optical axes of each lens are parallel to each other.

The photographic lenses 3a to 3d are integrally molded on one lens plate 4 made of transparent resin such as acrylic, and the photographic lenses 3e to 3h are integrally molded on the other lens plate 5.

A shutter substrate 7 is fixed inside the camera body 2 and has eight exposure apertures 6a to 6h formed therein corresponding to the photographing lenses 3a to 3h. The inner diameters of these exposure amounts D6a to D6h are all equal. On the shutter substrate 7, there are
Shafts 8.9 are installed at equidistant positions, and each rotatably supports a disk-shaped shutter plate 10.11. Therefore, from the axis 8, the exposure aperture 6a and the exposure aperture 6d are at the same distance, and the exposure aperture 6b and the exposure aperture 6C are at the same distance, and from the axis 9, the exposure apertures 6e and 6h are at the same distance, and the exposure aperture 6
f and 6g are equidistant.

Gear 1 is installed around the entire periphery of the shank plate 10.11.
0a and Ila are formed and mesh with each other. A stepping motor 12 is fixed to the front side of the shutter board 7, and a drive gear 13 fixed to the shaft of the stepping motor 11 meshes with a gear lOa of the shutter plate lO. Furthermore, the shutter board 7 has a reflective photosensor 14.
is attached to photoelectrically detect the reflective piece 17 fixed to the shutter plate 10 through the open lower a of the shutter board 7.

As shown in FIG. 4, two slots 7) 15a, 15b, 16a, 1
6b is formed. The slits 15a and 15b are on the same straight line from the center of the shirt shirt plate 10, and similarly the slits 16a and 16b are on the same straight line from the center of the shirt shirt plate 11.

Note that the slits 15, 15b or 16a,
16b does not necessarily have to be on the same straight line from the center of each shutter plate 1011, and can be positively shifted in consideration of the timing of photographing.

The slit lengths (lengths in the radial direction of the shutter plate) of these slits 15a, 15b, 16a, and 16b are equal to or longer than the inner diameters of the exposure openings 6a to 6h. Furthermore, the slit widths of the outer slits 15a and 16a (width in the circumferential direction of the shirt plate) and the slit widths of the inner slits 15b and 16b vary depending on the distance from the shafts 8 and 9, respectively. For example, if the slit width of the outer slits 15a and 16a is 1 mm, then the inner slit 15b.

The slit width of 16b is approximately 0.7 mm.

As the shirt flap plate 10 rotates, the slit 15a moves clockwise from the illustrated origin position P0, and the slit 15a moves clockwise from the illustrated origin position P0.
The exposure aperture 6a is opened and closed when passing through the exposure position P1. When the shirt cover plate 10 continues to rotate and the pickpocket 7) 15b passes through the second exposure position P2, the exposure opening 6b is opened and closed. Then, each time the pickpocket 7l-15b 15a passes through the third exposure position P3, the fourth exposure position P, and so on,
The exposure apertures 6c and 6d are sequentially opened and closed.

When the shirt flap plate 10 starts rotating clockwise, the gear 1
The mesh of 0a and lla causes the shirt flap plate 11 to rotate counterclockwise. Then, the slit 15a is located at the fourth exposure position P.
4, the pickpocket 7) 16a of the shirt shirt plate 11 rotates from the origin position Q0 to the fifth exposure position Q, and at the time of passing, the exposure opening 6e is opened and closed. The rotation of the shirt flap plate 10 is continued until the pickpockets 7) 15a and 15b reach the origin position P0 again, so the shirt flap plate 1 is rotated in conjunction with this.
1 continues to rotate counterclockwise, and each reaches the sixth exposure position Q.
&1 Slit 1 at 7th exposure position Qy, 8th exposure position Q,
Exposure openings 6f, 6g, and 6h are sequentially opened and closed by 6a and 16b. The time from when the first exposure aperture 6a is opened and closed to when the last exposure aperture 6h is opened and closed can be selected from either 1 second or 2 seconds by switching the rotational speed of the stepping motor 12. It is now possible to do so.

As shown in FIG. 3, between the cartridge loading chamber 18 and the winding chamber 19 provided in the camera body 2, there are eight cartridges separated by partition walls along the feeding direction of the film 20. Exposure frames 21a to 21h are formed. Exposure frame 21
The horizontal lengths from a to the exposure frame 12d and from the exposure frame 21e to the exposure frame 21h are each the same horizontal length as one frame of a 35 mm full-size screen.

The vertical length of each of the exposure frames 21a to 21h is approximately half that of a 35 mm full-size screen, and each exposure frame 21a to 21h is provided at a position where the longitudinal center portion of the film is exposed. Therefore, when shooting through such exposure frames 21a to 21h, as shown in FIG. Screens 24a to 24d, 24e to 24h
becomes exposed.

In addition, the horizontally long screen that connects each 4-frame continuous shooting screen 24a to 24d or 24e to 24h has a width of 6 mm on the top and bottom sides of the screen for one full-size frame.
The screen size for panoramic prints obtained when photographing is done by shielding the width (for example, 13°7±0.4mm x 3
6mm). As shown in FIG. 3, a space is opened between the continuous shooting screen 24d and the continuous shooting screen 24e by the central partition wall 25. Furthermore, the shape of the exposure frame is determined so that the horizontal size of the four continuous shooting screens 24a, 24d, 24e, and 24h is longer than the other quick shooting screens 24b, 24c, 24f, and 24g.

The film 20 is placed on a spool 2 provided in a winding chamber 19.
8 is wound up by rotating counterclockwise and pulled out from the cartridge 29 loaded in the cartridge chamber 18. The spool 28 has a motor 30 for winding the film.
is built in, and its driving force is transmitted to a film feeding mechanism 32 via a gear 31. The film feeding mechanism 32 receives driving force from the gear 31, and when winding the film, the gear 3
3 to drive the spool 28, and when rewinding the film, a rewinding fork 35 is driven via a gear 34.

Sprocket 3 is installed on the film perforation 20a.
6 is engaged and rotated as the film 20 is fed. The feeding amount of the film 20 is detected by a sprocket 36 and an encoder 39.

The encoder 39 is integrally fixed to the sprocket 36 and includes a signal plate 37 having radially formed through-hole slits, and a photo sensor 38 that photoelectrically detects rotation of the signal plate 37. The photosensor 38 counts the number of through-hole slits passed through the film when winding the film, and the moment the amount of film 20 fed reaches two 35 mm full-size frames, the motor 3 is activated.
Generates a stop signal of 0.

FIG. 5 is a block diagram showing the circuit configuration of the above-mentioned snapshot camera, and its photographing sequence is controlled by the MPU 40. The MPU 40 receives a release signal input from the release signal generation circuit 41 when the shutter button 41 is pressed and starts a photographing sequence. The continuous shooting interval setting circuit 43 performs continuous shooting at 8 frames/second or 4 frames/second depending on the set position of the frame number setting knob 44.
Set whether to perform continuous shooting for seconds.

The R/L mode switching circuit 45 switches the direction of rotation of the shirt shirt plate 10.11 during continuous shooting between forward rotation and reverse rotation, depending on the set position of the R/L setting knob 46. That is,
When the person being photographed performs right-handed movements,
By setting the R/L setting knob 46 to the index R, the R/L mode switching circuit 45 inputs a right-handed mode signal to the MPU 40, and when the R/L setting knob 46 is set to the index R, the R/L mode switching circuit 45 inputs a right-handed mode signal to the MPU 40. A left-handed mode signal is input. Further, the program ROM 4B stores a sequence program for continuous shooting, and includes the above-mentioned quick shooting interval setting circuit 43. A quick-shot photographing sequence is executed in response to a signal from the R/L mode switching circuit 45.

The driver IC 50 receives control signals and clock pulses from the MPU 40 and supplies drive pulses to the stepping motor 12. As is well known, stepping motor 1
2 rotates in proportion to the number of drive pulses supplied, so the rotation angle can be determined by the number of drive pulses, and the speed of rotation can be controlled by the frequency of the drive pulses.

The number of drive pulses supplied from the driver IC 50 to the stepping motor 12 is counted by a counter 51.

Then, the MPU 40 monitors the count value of the counter 51,
Each time the count value reaches a predetermined value, the driver IC50
send a control signal to.

Then, the driver IC 50 changes the frequency and polarity of the drive pulses supplied to the stepping motor 12 according to the control signal, and controls the speed and direction of one rotation of the stepping motor 12. Note that when one quick-shot sequence is completed and the shirt cover 10 returns to its original position, a reset signal is input to the counter 51, and its count value is cleared to "0".

Further, when the photo sensor 14 detects the reflective piece 17 fixed to the shirt shirt plate 10, it sends a detection signal to the MPU 40.

Then, the MPU 40 controls the photosensor 1 as described later.
Control is performed to accurately return the shirt shirt plate 10 to its original position by monitoring the detection signal from 4. Note that the reference numeral 53 indicates a driver that drives the motor 30 for film feeding.

The operation of the continuous shooting camera with the above configuration will be explained.

When photographing a right-handed person's golf swing from the top position to the follow-through position continuously at 8 frames per second,
Set the R/L setting knob 46 to the index "R" and the frame number setting knob 44 to the index "8". As a result, the shirt top plate 10 is rotated clockwise in FIG.
The driving of the stepping motor 12 is controlled so that images are taken continuously at a rate of frames per second.

When the subject starts a backswing and reaches the top position, the shutter button 41 is pressed. As a result, the stepping motor 12 starts driving, and the shutter plate 10 is rotated clockwise in FIG. 1 or 4 via the drive gear 13, and the shirt flap plate 11 is rotated counterclockwise. Then, the shutter plate 10 moves from the origin position P0 shown in FIG. 4 to the first to fourth exposure positions P+, Pz,
By rotating P3P4, the slit 15a
, 15b sequentially open and close the exposure apertures 6a, 6b, 6c, 6d, and the film 20 has continuous shooting screens 24a, 24b, 24c.
, 24d are exposed. Immediately after the snapshot screen 24d is exposed, the shutter plate 11 reaches the fifth exposure position Q from the origin position Q0, and subsequently moves to the sixth to eighth exposure positions Q,,Q,...
As it passes through Q, the slits 16a, 16b
The exposure openings 6e, 6f, 6g, and 6h are sequentially opened and closed.

FIG. 6 is a timing chart showing the above-described continuous shooting performed at 8 frames/second. When the shutter button 41 is pressed at the time of "T=0", the driver IC 50 supplies drive pulses whose frequency gradually increases to the stepping motor 12, thereby driving the stepping motor 12 while accelerating. By driving the stepping motor 12, the shutter plate lO is rotated while increasing the speed, and the slit 15 is rotated by 30 degrees from the origin position P0.
a reaches the exposure aperture 6a, and first the snapshot screen 24a is photographed. Hereafter, T,,T3,T,.

... Continuous shooting screen 24b at each time point of T8.

Photographing at 24c, 24d, ...24h is performed.

As is clear from the timing chart in FIG. 6, the shutter plate 10.
is rotated at high speed, and immediately after the shooting is completed, after deceleration,
rotated at low speed. As a result, for example, 4ms e c
The time interval between each quick shot can be extended to about 100 to 500 m5ec while each continuous shot screen is photographed with an exposure time of about 100 to 500 m5ec. Such rotation control of the shutter plate 10.11 is performed when the rotational position of the shutter plate 10 is at the counter 51.
The MPU 40 changes the frequency of the drive pulse supplied to the stepping motor 12 every time the count value of the counter 51 reaches a predetermined value.

In addition, each shirt plate 10 is proportional to the distance from the rotation center.
．． The inner slits 15b and 16b of 11 are the outer slits 15b and 16b.
(g) Since the circumferential speed is slower than that of slits 15a and 16a, for example, the time required for slit 15a to pass through exposure aperture 6a (in seconds) Δt1 and the time required for slit 15b to pass through exposure aperture 6b are Comparing the required time Δt2, Δ1. <Δt2. Therefore, if the inner diameters of the exposure apertures 6a and 6b and the slit widths of the slits 15a and 15b are made the same, the exposure amount of the quick-shot screen 24b will be larger than that of the quick-shot screen 24a. Particularly in continuous shooting, where the frames obtained by continuous shooting are often viewed side by side, variations in exposure become noticeable.

To deal with this, in this embodiment, the inner slit I is larger than the slit width of the outer slits 15a and 16a.
The slit widths of 5b and 16b are made narrower according to the distance from the axis 89, so that the exposure amount of each snapshot screen 24a to 24h is constant. Of course, the inner slit 1
Exposure openings 6b, 6c, 6f, 6 through which 5b, 16b pass
It is also possible to keep the exposure amount constant by making the inner diameter of g smaller than the inner diameters of other exposure apertures.

When the shutter plate 10.11 rotates 360 degrees and returns to the original position, the photosensor 14 photoelectrically detects the reflective piece 17, but the MPU 40 also sends several drive pulses to the stepping motor 12 via the driver IC 50. supply,
Thereafter, the stepping motor 12 is reversed, and when the photo sensor 14 detects the reflective piece 17 again, the stepping motor 12 is stopped. In this way, the reflective piece 17
By detecting this twice with the photosensor 14 and stopping the stepping motor 12, after one quick shot,
The shirt shirt plate 10 can be accurately stopped at the original position.

In this way, 8 frames of continuous shooting images 24a to 24 are printed on the film 20.
When the photographing of h is performed, the film feeding mechanism 32 is operated in response to the photographing completion signal, the motor 30 is driven, and feeding of the film 20 is started.

Then, by the encoder 39, the 35mm full size 2
When the feeding of a frame is detected, the motor 30 is stopped and the camera enters a standby state for the next photographing.

FIG. 7 conceptually shows the film 20 photographed as described above. As already explained, the four-frame quick-shot screens 24a to 24d have the same size as the panoramic print screen.

Therefore, by performing the conventional panoramic print processing, 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 printed in the size of two service prints.
Prints from a to 24d are also large enough. Note that during panoramic printing processing, a negative mask with the aperture size indicated by the two-dot chain line 55 in the figure is used, and the quick-shot screen 24a,
Vignetting occurs at the end of 24d. However, film 20
Since the horizontal size of the snapshot screens 24a, 24d is set to be large in advance in the above example, each frame of the print photograph 57 is of the same size as shown in FIG.

Currently, the panoramic print service is performed in units of one frame on a 35mm full-size screen, so as shown in Figure 8, continuous print photos 57.58 of 4 frames can be obtained from the continuous shooting screens 24a to 24h. . therefore,
If you connect the two print photos 57° and 58, it will become a continuous photo taken in one quick shot, and each frame will be lined up horizontally over time, which is very advantageous in terms of reproducibility of the quick shot scene. .

In addition, in the above-mentioned quick-shooting camera, the stepping motor 1
It is also possible to perform quick shooting by reversing 2. For example, when continuously photographing the golf swing of a left-handed player, the R/L setting knob 46 is set to the index "L" and the shutter button 41 is pressed. If a left-handed mode signal is input from the R/L mode switching circuit 45 at the time the release signal is input, the MPU 40 sends a control signal for reverse drive to the driver IC 50, and the driver IC 50 causes the stepping motor 12 to reverse polarity. The drive pulse is supplied.

When the stepping motor 12 is reversed, the shutter plate 1
0 is rotated counterclockwise, and the shutter plate 11 is rotated clockwise, and the continuous shooting screens 24h, 24g, 24f, . . . 24
Photographing is performed in the order of a. Then, for each continuous shooting, two printed photos 60.61 as shown in Figure 9 are printed.
is obtained. In this way, by arranging each frame sequentially from the right side over time, it is possible to reproduce an easy-to-read continuous shooting scene in accordance with the direction of movement of a left-handed player.

Furthermore, if it is desired to take continuous pictures of an exercise that continues for about 2 seconds, the frame number setting knob 44 is set to index "4" and the pictures are taken. As a result, driver IC50
A control signal of 4 frames per second is input from the MPU 40,
The driver IC 50 has a shutter speed Δt1. Δtz (
6), the shutter plate at the time of exposure, 10
．． To maintain the rotational speed of 11 constant, and to further reduce the rotational speed between exposures. As a result,
As shown by the broken line in FIG. 6, at the time of T1, the snapshot screen 2
After photographing 4a, the snapshot screen 24b appears at T3.
, and the 8 frames from continuous shooting screen 24a to 24h are 2
The photo will be taken in seconds.

Note that since the shooting interval can be changed simply by adjusting the rotational speed of the stepping motor 12, taking into consideration that the movement speed becomes slow at the beginning and end of the movement, for example, after shooting the quick shot screen 24a, the continuous shooting screen is It is also possible to make adjustments such as increasing the time interval between shooting the continuous shooting screen 24b and the time interval between shooting the continuous shooting screen 24h after shooting the continuous shooting screen 24g.

Above, we have explained an example of using two shutter plates to take 8 frames of a 35mm full-size screen in one snapshot, each with one slit for exposure. It is also possible to take 8 frames of snapshots using the 8 sheets of shirt plate that was formed, or to further increase the number of frames on the 35mm full-size screen by making the length of film used for one quick shot equal to 3 frames of a 35mm full-size screen. It is. Also,
Instead of increasing the number of shutter plates, the number of slits formed in one shirt plate may be increased to increase the number of frames on the snapshot screen. Furthermore, although it is advantageous in terms of simplifying the structure to interlock multiple shirt starter plates and rotate them simultaneously using one stepping motor, it is also possible to rotate each shirt starter plate at an appropriate timing using an individual stepping motor. You may let them.

[Effects of the Invention] As described above, according to the shutter device of the present invention, by rotating two or more shutter plates on both sides of the exposure apertures arranged in a straight line along the film feeding direction, Since exposure is performed by moving the apertures formed in each of the shutter plates sequentially across the exposure apertures, it is possible to take snapshots of images lined up in a row with a very simple structure, and it is possible to capture temporal continuity. It is possible to reproduce quick-shot scenes that make it easy to recognize gender.

In addition, by forming gears on each of the shirtta plates and meshing them, and adopting a configuration in which one shirtta plate is driven by a motor and the others are driven, the structure can be simplified, and the shirtta plate It is easy to adjust the rotational speed for each rotational phase, and the time interval between each exposure during continuous shooting and the shutter speed during each exposure can be easily set.
