【Example】

 -First Embodiment- A first embodiment of the present invention will be described with reference to Figs. 1 to 3, reference numeral 1 denotes a panoramic photographing adapter having a rectangular surface area larger than the opening area of the camera aperture opening 11. This panorama shooting adapter 1 is formed by punching out a non-light-transmissive flexible plastic sheet material such as polyethylene terephthalate having a thickness of about 0.1 to 0.15 mm to form a panoramic shooting screen. It has a panoramic opening 2, an abutting piece 3 that abuts a surface 12 on which the aperture opening 11 is formed, and a locking piece 4 that engages with a short side edge portion 11a of the aperture opening 11, and these are also formed at the same time during punching To be done.

The thickness of the sheet material (0.1 to 0.15 mm) is almost equal to or different from the step between the aperture forming surface 12 and the film guiding inner rail 13 shown in FIGS. It is smaller.

The shape of the panoramic photography adapter 1 will be described in more detail. The adapter 1 has a rectangular shape with a short side length A and a long side length B, and the short side length A. 2 is longer than the short side length F of the aperture opening 11 shown in FIG. 2 and slightly shorter than the interval between the film guiding inner rails 13, and the long side length B is the aperture opening 11. Is formed to have a size sufficiently larger than the long side length G of. The panorama opening 2 has a rectangular shape having a short side length C and a long side length D that are long in the long side direction of the adapter 1, and the length C of the short side is the short side length of the aperture opening 11. The length D is shorter than F, and the long side length D is slightly longer than the long side length G of the aperture opening 11.

The contact pieces 3 are formed symmetrically at the four corners of the adapter 1, and when the adapter 1 is punched from the sheet material, the contact piece 3 extends in the direction parallel to the long side from the short side edge. It is formed by the cut line 5 formed. The locking pieces 4 are formed symmetrically at both ends in the long side direction of the adapter 1, and a pair of cut lines 5 in the short side direction and from the end of each cut line 5 toward the panorama opening 2. It is composed of perforations 6 formed in parallel with the short side. The interval E between the left and right perforations 6 in the long side direction of the adapter 1 is slightly shorter than the long side length D of the panoramic opening 2.

When panoramic photography is performed using the adapter configured as described above, the left and right locking pieces 4 are folded along the perforations 6 in the same direction (aperture opening direction) by 90 degrees or more as shown in FIG. Bending, and while holding this bent state, each locking piece 4 is inserted into the aperture opening 11 along the short side edge portion 11a. When the bending force on the locking piece 3 is released while the locking piece 4 is inserted into the aperture opening 11, the elastic return force of the locking piece 4 causes each locking piece 4 to correspond to the aperture opening 11. The contact pieces 3 at the four corners are pressed against the aperture forming surface 12. As a result, the adapter 1 is attached to the aperture opening 11. Then, the adapter 1 limits the shooting screen frame of the aperture opening 11 to a panorama size which is long in the lateral direction (the film feeding direction) which is contracted from above and below.
