Abstract

PURPOSE:To allow real panoramic short to be executed in a panoramic mode by changing right and left angle of views from other modes to vary the photographing range between the panoramic mode and the other modes. CONSTITUTION:Film guide rail parts 2a escape from the bent part 10a of an aperture regulating plate 10 when a movable body 2 is moved in a film traveling direction with respect to a stationary body 1 in the panoramic mode. Then, the aperture regulating plate 10 is rotated clockwise around a shaft 12 by the energizing force of a spring 11 until the regulating part 10b comes into contact with a rising bent part 8a of a shutter base plate 8. Only the vertical direction with respect to the effective exposing region of the film is regulated in this state. While the size in the vertical direction of the film is the same as compared with a trimming mode, the size in the lateral direction of the film increases and the angle of view changes largely. The real panoramic short is executed in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a trimming camera capable of performing panoramic photography.

2. Description of the Related Art Cameras that can take pictures by switching between a panoramic mode and a normal shooting mode have been known. In this type of camera, as shown in Fig. 1θ, in normal shooting mode, the entire effective exposure area is exposed in a rectangle surrounded by vertical and horizontal solid lines, while in panorama mode, the entire effective exposure area is exposed in a rectangular area surrounded by horizontal dotted lines and vertical solid lines. As shown in the image above, I am trying to take panoramic shots by blocking light only at the top and bottom. When printing a print of film taken with this camera, in the panoramic mode, the print is printed at a size approximately twice the normal print size.

The problem that the original is trying to solve However, with the above structure, the print size in the vertical direction is the same as the normal size, and the print size in the horizontal direction is twice as large, so the print is spread out wide. The angle of view is the same as normal, so the drawback is that it does not allow for true panoramic shooting.

Therefore, an object of the present invention is to solve the above problem, and to make it possible to change the left and right angle of view in panoramic mode more than in other modes so that the shooting range in panoramic mode and other modes can be made different. Our goal is to provide cameras that can.

Means for Solving the Problems In order to achieve the above object, in the present invention, in the effective exposure area of the film, the size in the vertical direction is approximately the same in both the first mode and the second mode, while the size in the horizontal direction is the same. In the 2nd mode, the length is the same as that of a regular film, and the first
The mote is configured to restrict the length to the same trimming rate as the vertical direction. That is, it is configured to have a first mode in which the effective exposure area of the film is multiplied by a constant trimming rate vertically and horizontally, and a second mode in which a constant trimming rate is multiplied only in the vertical direction.

In the above configuration, the camera body is arranged between a fixed body having a film spool chamber, a first position with respect to the fixed body, and a second position in the left-right direction of the film from the first position. a movable body that is movable and capable of accommodating the film cartridge; in the first mode, the movable body is located at the first position relative to the defining body, while in the second mode, the movable body In contrast, the movable body may be located at the second position.

Functions and Effects of the Invention According to the above configuration, in the effective exposure area of the film,
The vertical size is almost the same in both the first and second modes, while the horizontal size is the same as the length of a normal film in the second mode, and the same trimming rate as in the vertical direction is applied in the first mode. I decided to restrict the length. As a result, the angle of view changes greatly in the horizontal direction in the film effective exposure area between the second mode and the first mode, so there is a large difference in print size and angle of view between the second mode and the first mode, and the true You will be able to take panoramic shots.

In other words, according to the present invention, the left and right angles of view change, and the shooting ranges in the second mode, that is, panoramic mode, and the first mode, that is, modes other than panorama, are different, whereas in the past, the angle of view is the same, and the print size is different. Because only the angle was different, it was not possible to take true panoramic shots. In the present invention, since the same trimming rate is applied in the vertical direction, it is possible to effectively use the space in the vertical direction. In other words, if the trimming rate is applied in multiple stages, the space in the vertical direction cannot be used effectively.

In the first mode, it is preferable to print in normal size. In this way, when printing, the image will be printed with the same magnification in both modes, so
When printing panoramic and cropped images, the laboratory system does not become complicated. That is, there is no need to change the magnification of the lens for image retention depending on the mode.

Furthermore, by changing the horizontal size of the camera depending on the mode, the entire camera becomes more compact, and the mode can be determined based on the overall shape of the camera.

Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 9.

The camera according to this embodiment, as shown in Fig. 1.2,
A camera body is formed by a fixed body 1 having a spool chamber 1a in which a take-up spool 6 is arranged and a movable body 2 having a film cartridge storage chamber 2c.

The movable main body 2 is movable relative to the fixed main body 1 along a guide portion (not shown). Box-shaped exterior members 4 and 5 are attached to the fixed main body 1 and the movable main body 2, respectively, to form an external appearance.

A pressure bonding plate 3 for pressing a film (not shown) onto the camera body formed by the fixed body 1 and the movable body 2 toward the subject in the optical axis direction is attached to the fixed body 1.

Also, on the subject side in the optical axis direction of the above film, there is a gloss 9
A one-piece base plate 8 is attached to the fixed main body 1. A photographing lens 7 is held on the glossy base plate 8. In order to guide light to the photographing lens 7, a rectangular opening 4a is formed in one of the exterior members 4, as shown in FIG.

On the other hand, the aperture regulating plate 10 is supported by a shaft I2 attached to the stationary body 1, and is attached to the stationary body 1. The aperture regulating plate IO has its regulating portion tab urged by a spring 11 to rotate in a direction away from the film surface, that is, clockwise in FIG. 1.2.

Therefore, in the above camera, during normal shooting, that is, in trimming mode, the aperture regulating plate IO is bent @1.
10 a is the film guide rail portion 2 of the movable main body 2;
The rotation of the regulating portion 10 is regulated by the end face of a.
b is perpendicular to the shooting optical axis (see Figure 1)
. In this state, as shown by the horizontal dotted line and the vertical dashed-dotted line in FIG. 6, the length is regulated by multiplying the same trimming rate in the upper, lower, left and right sides of the effective exposure area of the film.

On the other hand, in the panoramic mode, as shown in FIGS. 1 to 2, when the movable main body 2 is moved relative to the fixed main body I in the film running direction, that is, in the right direction in FIG. Since the aperture regulating plate 10 escapes from the bent portion 10a of the aperture regulating plate IO, the aperture regulating plate 10 rotates clockwise around the shaft 12 due to the biasing force of the spring II, and the regulating portion 10b
a. In this state, as shown by the horizontal dotted line and vertical solid line in Figure 6, the effective exposure area of the film is restricted only in the vertical direction, and compared to the above trimming mode, the vertical size of the film is Although they are the same, the horizontal size of the film is larger, and the angle of view changes significantly, allowing true panoramic shooting.

When returning the aperture from the panoramic mode to the trimming mode, move the movable body 2 to the fixed body l in the first position.
Move it to the left in Figure 2.

Then, the film guide rule part 2a comes into contact with the bent part 10a of the aperture regulation plate IO, and if the aperture regulation plate 10 is rotated counterclockwise around the shaft 12 while resisting the urging force of the spring 11, The regulating portion 10b is again positioned in a direction perpendicular to the photographing optical axis (see FIG. 1).

On the other hand, as shown in FIG. 3, a rack 2b is formed on the film guide rail portion 2a, and the movable main body 2
As the gear 13 moves, the gear 13 rotates. When the gear 13 rotates, the rotation is transmitted to the drive lever 20 shown in FIGS. 4 and 5 through a gear train (not shown).

As shown in FIGS. 4 and 5, the protrusions 20a and 20b at both ends of the drive lever 2° fit into the holes 18a and 19a of the field of view regulating plate 18, 19, respectively, so that the drive lever 20
are connected to the viewing field regulating plates 18 and 19. Therefore, when the drive lever 20 is rotated by the rotation of the gear 13, the field of view regulating plates 18, 19 are moved in parallel, and the size of the finder field of view 14 is changed between the trimming mode and the panorama mode. That is, FIG. 4 shows the field of view of the finder in trimming mode,
FIG. 5 shows the field of view of the finder in panoramic mode. The above-mentioned field of view regulating plate I819 is a guide member 17.17
are guided by.

Further, by rotating the gear 13 in accordance with the mode switching, the rotor 22 coaxially connected to the gear I3 rotates as shown in FIG. 7, and the magnet 31 for the panorama mode or the trimming mode The magnet 32 faces the film 103, and information can be written on the film surface.

As shown in FIG. 8.9, the rotor 22 for writing panoramic information or trimming information on the film 103 is arranged at the tip of the swing lever 21. As shown in FIG. This swing lever 21 is pivotally supported by a pin 23, and is constantly urged in the Y direction by a spring 24. The curved protrusion 21a of the swing lever 21 is in contact with the traveling plate 25, and restricts rotation of the swing lever 21. This running plate 25 is the first
a surface 25c, a second surface 25a recessed downward in FIG. 8 from the first surface 25'c, and an inclined surface 25b connecting both surfaces.
The protrusion 21a abuts on one of these surfaces. Therefore, when the protrusion 21a is in contact with the second surface 25c, the rotor 22 at the tip of the swing lever 21
is in film 103! On the other hand, the above swing lever 2
When the first protrusion 21a contacts the first surface 25c, the swing lever 21 rotates counterclockwise by the biasing force of the spring 24, and the rotor 22 contacts the film 103.
Panoramic information or trimming information can now be written on the film 103. On the other hand, the traveling plate 25 is biased in the X direction by a spring 28, and the traveling plate 25 biased by the spring 28 is locked by a locking member 27 to restrict movement in the X direction. The lock member 2
7 is biased in the opposite direction to the X direction by a spring (not shown).

The camera described above operates as follows to write panoramic information or trimming information on the film 103.

When a shutter button (not shown) is pressed to take a picture, a series of shutters are opened and closed to perform an exposure operation.

At the same time, the locking member 27 is driven in the X direction, and the running plate 25 is unlocked. Then, the running plate 25 moves in the X direction due to the urging force of the spring 28. The swing lever 21 is biased in the Y direction by a spring 24.
In other words, the projection 2]a is always in contact with the first surface 25c of the traveling plate 25, which is locked by the locking member 27. In this state, the locking member 27 moves in the X direction and the running plate 25
moves in the X direction, the protrusion $21a of the swing lever 21
passes through the inclined surface 25b and moves from the first surface 25c to the second surface 25a recessed downward in FIG. The swing lever 2I rotates counterclockwise around the bin 23 by the amount that the contact position of the projection 21a of the swing lever 2I changes, and the rotor 22 at the tip of the swing lever 21 comes into contact with the film 103. . When the rotor 22 comes into contact with the film 103,
The film 103 is magnetized. At this time, the hoisting operation member (
As the film 103 is moved from the cartridge (not shown) toward the spool by the operation of the film +03, panorama information or trimming information is sequentially written onto the film +03 by the rotor 22.

Immediately before the end of winding the film, the running plate 25 is moved in the opposite direction to the X direction against the force of the spring 28 in conjunction with the running of the film, and enters a charged state. This running board 2
5, the protrusion 21a of the swing lever 21 moves to the first position.
The surface 25a comes into contact with the second surface 25c via the inclined surface 25b, and the swinging lever 21 rotates clockwise around the pin 23 while resisting the biasing force of the spring 24, thereby removing the rotor 22 from the film 103. Let go.

When the charging of the traveling plate 25 is completed, the locking member 27
moves in the opposite direction to the X direction and locks the running plate 25,
Waiting for the next shooting action by pressing the shutter button.

According to the above embodiment, in the effective exposure area of the film, the size in the vertical direction is almost the same in both trimming mode and panorama mode, while the horizontal direction is the same as the length of the normal film in panorama mode, and in the trimming mode. The length can be restricted to the same trimming rate as the vertical direction. As a result, the angle of view changes greatly in the horizontal direction in the film's effective exposure area between panorama mode and trimming mode, so there is a big difference in print size and angle of view between panorama mode and trimming mode, making it possible to shoot true panoramas. Be able to do it. In other words, according to this embodiment, the left and right angle of view changes, and the shooting range is different between panoramic shooting and cropping shooting, whereas in the past, the angle of view was the same, and only the print size was different, so true panoramic shooting was not possible. could not be done. In this embodiment, since the same trimming rate is applied in the vertical direction, it is possible to effectively use the space in the vertical direction. In other words, if the trimming rate is applied in multiple stages, the space in the vertical direction cannot be used effectively.

Further, in this embodiment, it is preferable that the prints of the film taken in the trimming mode be of normal size. In this way, when printing, the image will be printed at the same magnification in both modes, so
When printing a panorama photograph or a cropped photograph, the Raho system does not become complicated. That is, there is no need to change the magnification of the lens for image retention depending on the mode.

Alternatively, if you change the size of the camera in the horizontal direction by moving the movable body 2 with respect to the fixed body 1 using a mote, the entire camera will become more compact, and the mode can also be determined based on the shape of the entire camera. becomes.

Further, since it is a combination of the panoramic mode and the trimming mode and there is no normal mode (trimming magnification l), the vertical size of the camera is small, making the camera compact.
