Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a croppable camera capable of shooting standard, panoramic, half and various other sizes and / or shapes.

[0002]

2. Description of the Related Art In a conventional camera, when taking pictures of various sizes such as standard, panoramic, half, and the like, an adapter is attached and a light shielding plate is provided inside the camera.

[0003]

However, in these conventional techniques, when the adapter is attached, the size cannot be switched in the middle of the same film.
When a light-shielding plate is attached inside the camera to switch the size, the size can be switched in the middle of the same film, but there are various problems such as the mechanism becoming complicated and the shape of the aperture being specified.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve these problems of the prior art, in which a camera housing is provided with a trimming sheet guide having a film aperture for photographing at least a standard size, and various types. Trimming sheet having a sheet aperture for shooting the size and / or shape of the sheet and moving along the trimming sheet guide, a sheet position setting unit for selecting the type of the sheet aperture, and a viewfinder window are available. Provide a camera.

Further, the present invention provides a trimming sheet guide, in which a camera housing has at least a standard size film aperture and a sheet position detection window, and a sheet aperture and a sheet which capture images of various sizes and / or shapes. A trimming sheet that has a finder window and a sheet position detection mark and moves along the trimming sheet guide, a sheet moving motor that winds the trimming sheet, a sheet rewinding spring that rewinds the trimming sheet, and the sheet position. Provided is a camera capable of trimming photography, which includes a photo interrupter for detecting a detection mark, a sheet position setting unit for selecting the type of the sheet aperture, and a finder window.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 are a schematic diagram and an operation explanatory diagram of the configuration of an embodiment of the present invention, in which the same parts are designated by the same reference numerals, 1 is a camera housing, 2 is a film aperture 2a for photographing in a standard size, and FIG. Seat position detection window 2b
And a trimming sheet guide 3 having a sheet aperture 3a for photographing various sizes and / or shapes.
And sheet finder window 3b and sheet position detection mark 3c
And a trimming sheet 4 that moves along the trimming sheet guide 2, a sheet moving motor for winding the trimming sheet 3, and a trimming sheet 3
Is a sheet rewind spring, 6 is a photo interrupter that detects the sheet position detection mark 3c, 7 is a sheet position setting unit that selects the type of the sheet aperture 3a, 8 is a finder window, 9 is a film cartridge, and 10 is a film. is there.

Next, the operation in such a configuration will be described. FIG. 1 is a schematic diagram of the configuration of an embodiment of the present invention,
2 is a schematic diagram of the configuration of the sheet position setting unit 7, FIG. 3 is a schematic diagram of the configuration of various apertures of the trimming sheet 3, and FIG.
3 is a flow chart for explaining the operation of the trimming sheet that moves along the trimming sheet guide 2.

In FIG. 4, first, when the type of the panorama size of the seat aperture 3a is selected by the seat position setting unit 7 (step 1), it is confirmed whether or not the seat setting is changed (step 11), and the CPU or the like operates. ,
When the sheet moving motor 4 winds up and moves the trimming sheet 3 (step 2), and the photo interrupter 6 detects the panorama size sheet position detection mark through the sheet position detection window 2b, the sheet moving motor 4 stops and the panorama size is detected. The sheet aperture of 2 is positioned at the center of the film aperture 2a. If it is desired to select another seat aperture, the routine from step 11 is repeated. When the seat aperture is determined and it is confirmed that the size is not half size (step 3), a release button (not shown) is pressed (step 4) and a picture is taken (step 5). When the photographing is completed, the sheet moving motor 4 reversely rotates, the sheet rewinding spring 5 rewinds the trimming sheet 3 (step 7), and when the photo interrupter 6 detects the standard size sheet position detection mark, the sheet moving motor 4 stops. Then, for example, a standard size initial state is set.
It should be noted that, after the shooting is completed, the mode is not returned to the initial state, stays in the same position until another type of sheet aperture is selected, and when another type of sheet aperture is selected, the mode is repeated from step 1 again. You can also do it (step 7).

Next, the operation of half-size shooting will be described. When the half size of the sheet aperture 3a is selected by the sheet position setting unit 7 (step 1), the sheet moving motor 4 winds the trimming sheet 3 (step 2) by the action of the CPU or the like, and the photo interrupter is passed through the sheet position detection window 2b. When 6 detects the half size sheet position detection mark, the sheet moving motor 4 stops and positions the half size sheet aperture on the upper half of the film aperture 2a. Here, a release button (not shown) is pressed (step 41) to take a picture with the upper half of the film aperture 2a (step 5).
1) Then, it is checked whether the number of frames to be photographed is the second frame when the photographing is completed (step 52), and if it is the first frame, the sheet is moved to the lower half of the film aperture 2a (step 21), and the step is performed. 41, the sheet rewind spring 5 moves the trimming sheet 3 when it is the second frame.
Is rewound (step 71), for example, an initial state of a standard size is set.

If another sheet aperture is selected during half-size shooting (step 32), and one half-size image has already been shot (step 3).
3) After winding the film (step 62),
The trimming sheet 3 is moved (step 2). When the first half-size image is taken, the trimming sheet 3 is moved without winding (step 33) (step 2).

[0011]

As described above, according to the structure and method of the present invention, various sizes and / or sizes can be obtained with a simple structure.
Alternatively, it is possible to provide a camera capable of trimming photographing for photographing a shape.
