り、経済的でなかった。Conventionally, in order to enable standard screen shooting and special screen shooting as described above, a mechanism for changing the shape of the shooting screen between the standard screen and special screen has been built into one camera, and the camera can change the shape of the shooting screen as needed. A camera is known in which the photographing screen is changed and the viewfinder field of view is also changed (for example, see U.S. Pat. No. 3,678,834). However, such conventional cameras have a complicated structure. It is inevitable that the cost will increase, and for users who do not intend to take pictures of special screens, the system will have an unnecessary mechanism, which is not economical.

0.2 yen). Therefore, the light shielding member 81 needs to have a thickness that does not allow the film F to come into contact with it. A suitable material for the light shielding member 81, which is installed in such a small space and requires durability, is a thin metal plate (thickness 0.1 mm to 0.15 mm). However, plate-shaped members are prone to surface distortion (flatness) and burrs of metal pieces due to press die cutting, and since they are thin plates, it is necessary to remove burrs after die cutting, and these distortions occur. If the surface were to fly out, the metal pieces could potentially damage the film F.

ことを防止している。The procedure for attaching and detaching is as follows: without pressing the button 26 of the jig 21, insert the pin 22 into the long hole 3fc of the light shielding part 31a, and into the engaging part 3.
It is made to penetrate through the hole 31d of 1b. From this state, when #26 is pushed against the spring 25, the pin 22 moves toward the center, and the engaging portion 31b is moved against the spring 34 to the position 1 shown by the two-dot chain line in FIG. As a result, the left and right tips of the re-engaging portion 31b are located within the dimensional range of the left and right edges of the aperture of the standard screen frame 2, so that attachment and detachment are possible. Note that, as described above, the light shielding portion 31 is located at the small diameter portion of the pin 22.
By holding a, the entire light shielding member 31 is held. Also, when installing it on the camera body CB,!
When A26 is released, the engaging portion 31b enters the position shown by the solid line in FIG. 18, thereby setting the light shielding member 31. Furthermore, in order to prevent the light shielding member 31 from accidentally falling off from the jig 21, a sheet-shaped magnet 27 is provided in FIGS. 18 and 31. By constructing this magnet 27 and the guide member 32 of the light shielding member 31 described above with a magnetically attracted material, the I:J light shielding member 31 can fall off from the jig 21 by loosening the push of the button 26 of the jig 21. This is prevented.

く、操作が容易となる。Set the light shielding member 31 on the jig 21 and attach the camera body CB.
When aligned with the standard screen frame 2 of
Although it may be psychologically unsettling for the user, by applying the color scheme as described above, it is possible to visually recognize that the light shielding member 31 overlaps the standard screen frame 2. Further, the periphery of the standard screen frame 2 is generally solid black, and it can be seen at a glance that the light shielding member 31 for special screen photography is set. Furthermore, when the light shielding member 31 falls off from the jig 21 by mistake, in order to fit the pins of the jig 21 into the long holes 31c of the light shielding member 31 again, it is necessary to visually check the jig 21.
It suffices to align it within the boundary between white and black of the light shielding part 31a, which facilitates the operation.

なお、上記各実施例の遮光部材は、通常、以下に説明す

This focus plate is normally used together with the light shielding member 1 or 31 that changes the screen frame size described above. Figure 20 shows the focus plate 41 attached to the finder optical system of the camera, and Figure 21 shows the focus plate 41 attached to the finder optical system of the camera.
The appearance is shown when is dedicated to panorama.

In addition, during normal shooting, a light receiving element 55 for performing blur metering in the finder is arranged to receive light that has passed through the mirror 53, focusing plate 41, and pentaprism 54, while during flash shooting, a light receiving element 55 for performing blur metering is placed on the film surface. A light receiving element 56 for performing real-time photometry is arranged so as to receive the reflected light from the film F surface when the mirror 53 is raised.

・露出結果が大きく異なることが防止される。The profile of the focusing plate 41 shown in FIG. 21 is the same as that of the conventional one, and there are light shielding parts 42 and 43 outside the upper and lower frames for displaying the special screen shooting range, that is, the special screen viewing area 44 within the viewfinder field of view. The top surface (42) of the side facing the photometric system installed inside the camera body B is printed in standard chart gray (or a color intermediate between white and black), and the bottom surface (43) of the opposite side is printed printed in black. By making the light shielding part 42 facing the photometry system gray in this way, it absorbs less light than if it were black, so it can be seen in the finder when the focus plate 41 for special screens is attached. The change in the photometric value compared to that when a standard reticle is attached is reduced. In other words, it is possible to prevent the photometry and exposure results from differing greatly between special screen shooting and standard screen shooting.

の場合に比べて吸収されることなく反射されるために、
測光値が小さくなる程度を抑えることができる。Note that photometry within the finder measures the light that is blocked by the focusing plate 41, so when the focusing plate 41 having the light blocking parts 42 and 43 for special screens as described above is attached,
It goes without saying that it is inevitable that the amount of light will be lower than when a standard screen focusing plate without a light shielding part is installed, but the reflected light that reaches the pentaprism 54 will be affected by the light shielding part 42. Because it is gray, it is reflected rather than absorbed compared to black, so
It is possible to suppress the degree to which the photometric value decreases.

また、第２１図において、焦点板４１の表面側が焦点面
となっており、もし画面域と同じ高さの面で印刷すると
、印刷の厚みでピント面がずれる。In addition, in FIG. 21, the front side of the focusing plate 41 is the focal plane, and if printing is performed on a plane at the same height as the screen area, the focal plane will shift due to the thickness of the printing.

薄板を貼ってもよい。Therefore, the portion of the focusing plate 41 on which the printing ink is applied is lowered by the printing thickness (approximately 20 μm to 30 μm) below the screen area, and printing is performed there. In addition, since both matte surfaces of the focus plate 41 have a fine R uneven surface such as a Fresnel lens, if you print on these surfaces as they are, the boundary line between the special screen viewing area 44 and the printed area will not be clear. By lowering it as above, that problem disappears. Note that instead of printing, paint may be applied or a thin plate may be pasted.

説明する。FIG. 22 shows a storage case 62 that houses and stores the light shielding member 31, the jig 21, the focus plate 41, and the holder 61 for setting the focus plate 41 in the camera body. Reference numeral 62 consists of a saucer 63 that can be opened and closed, and a case body, and the case body has 664 with various profiles for inserting each member. The jig 21 and the light shielding member 31 are inserted into the hole in an overlapping manner, and at that time,
The light shielding member 31 is placed inside the hole so that the same condition as when the light shielding member 31 and the jig 21 are attached to the camera body is obtained.
A groove 65 into which the engaging portion of is inserted, a convex portion 66 having the same shape as the convex portion 8 of the camera body, etc. are formed. By storing various components in the storage case 62, it is possible to prevent rattling, distortion, scratches, etc. due to rattling during storage. Even when taking it out from the case 62, the pin 22 of the jig 21 and the holes 31c and 31d of the light shielding member 31 fit together, making the operation easy. In particular, the light shielding member 31 is thin,
It is easily distorted, so it needs to be stored securely.
By using the storage case 62, this request can be met.Next, a method for displaying whether the camera is set to a special screen shooting state will be described.

ムであることを伝える必要がある。When the light shielding members 1 and 31 are installed for special screen photography, or when the focus plate 41 is installed inside the finder to visually confirm the shooting area of the special screen, the attached focus plate may not be the same as described above. As shown in Figure 30, if the standard (old-fashioned) size screen area E 35 rm and the special screen area can be displayed simultaneously in the viewfinder, one film loaded in the camera can be photographed. During this process, the user may forget whether the camera is in a special screen shooting state or a standard screen shooting state. Furthermore, when sending film for processing and printing after shooting, it is necessary to inform the user that the film was shot using a special screen at a laboratory or processing/printing agency.

図は同フィルムをカメラにセットする様子を示す。Means for dealing with this are shown in FIGS. 23 and 24. FIG. 23 shows the state in which the sticker 71 indicating the special screen shooting state is pasted on the film container 72.
The figure shows how the film is loaded into the camera.

シール７１はカメラにフィルムを装填する前、すなわち
撮影前にフィルム容器７２に貼り付ける。The sticker 71 is attached to the film container 72 before loading film into the camera, that is, before taking pictures.

ような表示（この例では横縞模様）が形成されている。In addition, the seal 71 has a notch (or transparent part) 71a formed in its center, and when the sticker 71 is pasted on a predetermined part of the film container 72, it passes through the notch 71a and attaches to the film container 72. A part of the displayed film information is visible, and a display (horizontal striped pattern in this example) is formed around the notch 71a to indicate the special screen shooting state.

When the camera back cover 73 is closed, the display on the sticker 71 and the film information displayed on the film container 72 itself can be viewed through a display window 74 provided on the back cover 73. In this way, the user can easily know whether the camera is in the standard screen shooting mode or the special screen shooting mode during shooting, and can also order the film after shooting for its own development and printing.
