Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera device, and more particularly to a camera device that simultaneously takes a plurality of identification photographs and the like.

(Prior Art) In the case of taking a certification photograph such as a resume or a passport, in recent years, a camera device capable of taking a plurality of photographs at the same time by one photographing has been used. By using this camera device, it is possible to take an image in a short time and at low cost even when a plurality of identification photographs are required.

The structure of the main body of the camera device is roughly as follows. That is, a plurality of taking lenses are arranged side by side in the front part of the camera body (for example, two taking lenses are horizontally arranged horizontally or four taking lenses are arranged in a vertical and horizontal grid pattern). A plurality of images of the same subject are formed in parallel on the image receiving surface of an internal film or the like by the respective photographing lenses.

By the way, the size of a photograph required as a certification photograph varies depending on its application (for example, the size of a resume photograph is required to be smaller than the size of a passport photograph). Under such conditions, it is necessary to change the size of the image of the subject shown in the photograph in accordance with the size of the photograph.

Japanese Patent Application No. 60-74055 discloses a camera device that can meet such needs and can perform shooting without waste according to the required size and number of photographs.
That is, this camera device is a camera body having a structure in which a conversion lens capable of changing the image magnification without changing the distance between the subject position and the image plane position simultaneously projects a plurality of photographs on one image receiving surface. It is designed to be detachably attached to the taking lens, and by appropriately attaching this conversion lens to the taking lens, it is possible to obtain different size images of the same subject on one image receiving surface. is there.

The camera device is very excellent in that a plurality of subject images of different sizes can be formed on the same film without changing the shooting distance, but all the subject images projected on the film are Since the poses are the same, for example, if you want to take a photo not only from the front but also from the side or the best angle of view, you should take a new film for each pose. There is a need. If this is done, a plurality of pictures will be produced for each pose, and if the number of pictures for one pose is not large, extra pictures will be taken. This increases the shooting cost and is wasteful.

(Object of the Invention) The present invention has been made in view of such circumstances, and a plurality of images of the same subject having different sizes and arbitrary poses can be obtained by a simple configuration without changing the shooting distance. An object of the present invention is to provide a camera device that can be formed on one film.

(Structure of the Invention) In order to achieve the above object, a camera device according to the present invention is an exposure device for selectively exposing at least one of a plurality of sections on an image receiving surface on which a plurality of images arranged in parallel in two rows are formed. In addition to providing the device, as a specific configuration thereof, a curtain member having a through hole formed at a predetermined position is provided in front of the upper portion and the lower portion of the image receiving surface, respectively. In this configuration, the through holes can be wound so that the positional relationship of the through holes changes.

That is, a plurality of taking lenses are arranged in parallel, and a camera body for forming a plurality of images arranged in parallel in two upper and lower stages on one image receiving surface; and a camera body detachably attached to at least one of the taking lenses. A camera device comprising a conversion lens for changing an image magnification without changing a distance between image plane positions, and an exposure device for selectively exposing at least one of a plurality of image forming sections on the image receiving surface. The exposure device is provided in front of the upper portion and the lower portion of the image receiving surface, and a pair of upper and lower curtain members each having a through hole formed at a predetermined position, and end portions of these curtain members are fixed to each other. And a pair of upper and lower take-up drums capable of taking up each of the curtain members regardless of whether it is rotated in the forward or reverse direction, and the take-up drums. rotation The winding operation member that winds each of the curtain members around each winding drum is provided, and the engagement between the winding operation member and each winding drum is a winding operation of the winding operation member. It is characterized in that the positional relationship of the through holes between the both curtain members is changed depending on the direction.

The exposure apparatus may be a light-shielding mechanism provided separately from the shutter, or the exposure apparatus itself may be a mechanism having a shutter function. Further, “in front of the image receiving surface” where the exposure device is provided means
The position on the subject side with respect to the image receiving surface means the position before or after the taking lens, and when the shutter is provided separately, the position before or after the shutter.

In the above, "image receiving surface" means an image forming surface on which a negative film, a photosensitive material such as a film unit of an instant camera or an image pickup element such as a CCD element in an electronic camera is arranged, and "a change in image magnification" Is the change in the size of the subject image formed on the image surface (that is, on the image receiving surface),
It means making an image smaller or larger by a conversion lens. When the conversion lenses are attached to the plurality of photographing lenses, the degree of "change in image magnification" due to the respective conversion lenses may be different.

(Examples) Examples of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a schematic view showing a camera apparatus according to the first embodiment, which has a structure in which a conversion lens 2 is detachably attached to a camera body 1.

At the front part of the camera body 1, four photographing lenses 3 are arranged in a grid pattern of up, down, left and right.
One film 4 is set inside the camera body 1 located at the rear of the film. Further, an opening 5 for inserting and removing the film 4 is provided on the upper portion of the camera body 1.

The conversion lens 2 is attached to the taking lens 3 of the camera body 1.
When shooting is performed with the lens not attached, the subject 6 shot by each shooting lens is formed as an image 8 of a size indicated by a broken line on each of the four screens 7 on the surface of the film 4. . Each image 8 is formed with the same size.

A shutter 9 and an exposure device 10 are shown by a chain double-dashed line in the figure, and the exposure device 10 is provided with a mechanism for exposing at least one of the four screens 7. Therefore, the four images 8 shown in the figure are obtained when the exposure device 10 is set in a state where all four screens 7 are exposed and the shutter 9 is operated.

Next, with the exposure device 10 kept in a state of exposing all four screens 7 as described above, the conversion lens 2
When one of the taking lenses 3 is attached to take a picture, the size of the image 11 formed on the screen 7 corresponding to the taking lens 3 to which the conversion lens 2 is attached is different from that on the surface of the film 4. It is smaller than the images 8 formed on the three screens 7. The image shown by the one-dot chain line in the figure is the image
Indicates 11.

At this time, the image 11 is smaller than the image 8 because the image magnification is reduced by attaching the conversion lens 2 to the taking lens 3. If this point is explained further in detail, as shown in FIGS. 2a and 2b, the conversion lens 2 is placed in front of the taking lens 3 (that is, the subject 6 side).
This is because the focal length of the lens becomes smaller and the position of the principal point of the lens moves toward the film 4 side. That is, in the case of only the taking lens 3, the lens principal point position is the point A (first
2a), while the conversion lens 2
When you attach the point B (2b
The main point position moves to (Fig.), Which causes the image magnification (L ₁ / L ₂ )
Is small (L ₁ ′ / L ₂ ′).

FIG. 3 shows an example of a specific configuration of the conversion lens 2 and the taking lens 3. Conversion lens 2 is 3
The taking lens 3 is made up of three lenses 3a, 3b and 3c.

Although FIG. 1 shows the conversion lens 2 attached to only one of the four taking lenses 3, it is possible to attach the conversion lens 2 to two or more taking lenses 3 if necessary. Of course. Further, if desired, the conversion lenses 2 having different focal lengths may be attached to the respective photographing lenses 3 and
It is also possible that the images of the four screens 7 on the surface of the film 4 all have different sizes.

In addition, although the present embodiment shows a camera device that forms a small image by attaching the conversion lens 2, it is also possible to form a large image by attaching the conversion lens 2 conversely. This is achieved by attaching to the taking lens 3 a conversion lens 2 which has a large focal length when combined with the taking lens 3.

On the contrary to the present embodiment, it is also possible to perform initial adjustment with the state in which the conversion lens 2 is attached as a standard, and form a large or small image with the conversion lens 2 removed.

The conversion lens 2 is attached to the taking lens 3 by, for example, screwing. However, as long as the optical axes of the conversion lens 2 and the taking lens 3 can be aligned with each other, another attachment structure such as a bayonet type can be used. Needless to say.

Further, in the present embodiment, the film 4 is used on the subject image receiving surface, but other photosensitive materials or image pickup elements can be used as long as the subject can be imaged.

FIG. 4 is a detailed view of the shutter 9 and the exposure device 10 shown by the chain double-dashed line in FIG.

The shutter 9 is provided with four shutter mechanism parts 12 on each optical axis connecting each photographing lens 3 in FIG. 1 and each screen 7 on the film 4, and four shutter mechanism parts 12 are operated by one push button operation. All the mechanical parts 12 can be opened and closed.

The exposure device 10 is provided between the shutter 9 and the body light-shielding frame 13 attached to the front surface of the camera body 1 (see FIG. 1).
Similar to the shutter 9, four rectangular windows 14 and 15 are formed on the optical axis 13 along the optical axis connecting the taking lenses 3 and the screens 7, respectively.

The exposure apparatus 10 is formed in upper and lower two stages, and a film-shaped curtain shutter 18 having both ends fastened to the rewinding drum 16 and the winding drum 17 is built in each stage. The lower end of the switching dial 19 meshes with the upper end of the winding drum 17, and the curtain shutter 18 can be wound up by rotating the switching dial 19 in either the left or right direction.

FIG. 5 shows a curtain shutter winding structure of the exposure apparatus 10.

The winding drum 17 is composed of an upper drum 17a and a lower drum 17b.When the switching dial 19 is rotated to the right, the lower drum 17b rotates simultaneously with the start of rotation of the switching dial 19, while the upper drum 17a is slightly delayed. When the changeover dial 19 starts to rotate and is rotated counterclockwise, the upper drum 17a is rotated at the same time as the start of rotation of the changeover dial 19, while the lower stage drum 17b starts to rotate with a slight delay. There is.

The curtain shutter 18 and the rewind drum 16 are also the winding drum 17
Similarly, it is divided into an upper curtain shutter 18a, a lower curtain shutter 18b, an upper drum 16a, and a lower drum 16b. Rewinding springs 20a are provided on the upper drum 16a and the lower drum 16b, respectively.
And 20b are provided so that a force for rewinding the upper curtain shutter 18a and the lower curtain shutter 18b to the respective drums 16a, 16b is always applied to the respective curtain shutters 18a, 18b. As shown in the figure, a state in which both the curtain shutters 18a and 18b are fully rewound on the respective rewinding drums 16a and 16b, that is, a state in which the switching dial 19 is not rotated will be hereinafter referred to as a normal state.

Each curtain shutter 18a, 18b has a horizontally long rectangular opening 21a and 21b.
In the normal state, the openings 21a and 21b are shaped and positioned so that the four windows 14 shown in FIG. 4 are not blocked by the curtain shutters 18a and 18b.

As shown in FIG. 6, in addition to the openings 21a, 21b, the curtain shutters 18a, 18b have openings 22a, 2 of about half the size thereof.
One 2b is formed for each. These openings 22a, 22b
The mutual positions are shifted to the left and right by one section separated by a broken line in the figure. The size of this one section is the switching dial 19
The size is equal to the amount of movement of the curtain shutter 18 wound by the winding drum 17 when one frame is fed by turning (see FIG. 5). Therefore, the switching dial
The portion of the curtain shutter 18 appearing in each window 14 (see FIG. 4) of the exposure apparatus 10 is switched for each frame feed of 19. The numbers above the curtain shutter 18 in the figure are 1 in order from the end of the curtain shutter 18 on the winding drum 17 side.
Numbers are given to each section. Above openings 21a and 2
1b is located across the sections of numbers (1) and (2), and openings 22a and 22b are located at numbers (6) and (5), respectively.

FIG. 7 is a view on arrow VII of FIG. 5, showing the switching dial 19 in the normal state.

In the figure, the index 23 points to the display 24 on the changeover dial 19, but every time the changeover dial 19 is rotated 30 °, it is advanced one by one, and the other displays 25, 26, 27, 28 and 29, 30 are displayed. Is also pointed out.

As described above, the windows 14 (see FIG. 4) of the exposure apparatus 10 are not shielded by the curtain shutter 18 in the normal state shown in FIGS.
When the push button operation (see FIG. 4) is performed, four images are formed on each screen 7 (see FIG. 1) of the film 4. That is,
You can get 4 photos of the same pose.

Next, description will be made regarding the case of taking pictures of two different poses.

In this case, first, the display 29 of the switching dial 19 in FIG. That is, the four-frame switching dial 19 is rotated counterclockwise. FIG. 8 shows the state in which the first frame is rotated counterclockwise for the first time. As is apparent from the figure, the upper curtain shutter 18a has moved one frame to the right from the normal state, while the lower curtain shutter 18b remains stationary in the regular state. This is because, as outlined in the explanation of FIG. 5, when the winding drum 17 is rotated counterclockwise, the lower drum 17b is delayed by one frame with respect to the upper drum 17a. Therefore, the switching dial 19
From the second frame of the rotation, the upper and lower drums 17a and 17b rotate together, and along with this, the upper and lower curtain shutters 18a and 18b also move to the right.

FIG. 9 shows the state of the curtain shutter 18 when the four-frame switching dial 19 is rotated counterclockwise from the normal state in this way. The symbols I a, I b, II a, and II b in the figure are given corresponding to the positions of the four windows 14 of the exposure apparatus 10 in FIG. The openings located at IIa and IIb are the openings 22a and 2 located at the numbers (6) and (5) in FIG.
2b, the opening 22a is rolled up by four frames IIa
In addition, the opening 22b is wound up by three frames by the slow movement of the lower drum and moved to IIb. If shooting is performed in the state shown in FIG. 9, film 4 corresponding to II a and II b
Images are formed on the upper and lower two screens 7 (see FIG. 1).

Then, this time, the display 30 of the switching dial 19 is set to the index 23. That is, the switching dial 19 is further rotated one frame to the left to move the openings 22a and 22b to the positions of Ia and Ib, respectively. If shooting is performed in this state, images are formed on the upper and lower two screens 7 (see FIG. 1) on the right side of the film 4 corresponding to I a and I b.

In this way, the screen 7 of the film 4 shown in FIG. 1 is exposed twice, and the image is taken in two steps. If the subject changes its pose during that time, a different pose will be taken for each image. Can be obtained.

Next, the case of taking pictures of different poses one by one will be described.

In this case, the switching dial 19 is rotated to the right, contrary to the case of taking the two images. The first frame is the upper drum 17a
Due to the slow-moving structure with respect to the right rotation, only the lower curtain shutter 18b moves and the upper curtain shutter 18a remains stationary, as shown in FIG.

FIG. 11 shows a state in which the switching dial 19 is further rotated by one frame and the display 25 is aligned with the index 23. At this time, the opening 21a that was located across I a and II a
However, since it is moved so as to be located only at I a, if an image is taken in this state, an image is formed on the upper right screen 7 (see FIG. 1) of the film 4 corresponding to I a.

After that, by further rotating the selector dial 19 one frame to the right and taking pictures at the positions where the displays 26, 27 and 28 are aligned with the index 23, when the display 26 is displayed, the opening 22b is IIb, and when the display 27 is displayed. Since the opening 22b is located at Ib and the opening 22a is located at IIa in the case of the display 28, the lower left, right,
An image is formed on each of the upper left screens 7 (see FIG. 1).

In this way, by exposing each of the screens 7 of the film 4 shown in FIG. 1 one by one and photographing four times, it is possible to obtain photographs with different poses for all four sheets.

As shown in FIG. 7, in order to be able to confirm which screen 7 of the film 4 shown in FIG. 1 is exposed during the above four shots, two shots, and one shot. Each of the displays 24, 25, 26, 27, 28, 29, 30 of the switching dial 19 is provided with an identification symbol.

FIG. 12 shows the upper curtain shutter 18a at each display position.
2 illustrates the positional relationship between the lower curtain shutter 18b and the positions I a, I b, II a, and II b corresponding to the windows of the window 14 of the exposure apparatus 10. In the figure, the serial numbers given to the curtain shutters 18a and 18b correspond to the serial numbers in FIG.

If the conversion lens 2 is attached to the photographic lens 3 as shown in FIG. 1 during the four-shot, two-shot, and one-shot shooting described above, the shooting can be performed for each pose. You can project pictures of different sizes.

(Effects of the Invention) As described in detail above, the camera device according to the present invention selectively exposes at least one of a plurality of sections on the image receiving surface where a plurality of images are formed in parallel in two rows. An exposure device is provided, and as a specific configuration thereof, a curtain member (curtain shutter) having a through hole (window) formed at a predetermined position is provided in front of the upper and lower portions of the image receiving surface, and both curtain members are provided. Is configured so that the positional relationship of the through holes between the both curtain members can be changed, so that the selective exposure can be performed by changing the winding positions of these curtain members. Not only this, the positional relationship of the through holes between the curtain members can be changed to perform the selective exposure by switching the direction in which the curtain members are wound up, so that each curtain member is formed. The number of through holes is small Can perform various selective exposures, and can achieve this with a simple structure.

Therefore, according to the present invention, a plurality of images of the same subject can be formed on one image receiving surface in different sizes and in arbitrary poses without changing the shooting distance with a simple configuration.
