 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing an appearance of a 135 type film to which the present invention is applied, showing a state in which a predetermined amount of a film leader extension portion 2 is pulled out from a patrone 1. At the middle of the film leader extension portion 2, there is provided a leader portion cutting line 3 which is a weak line such as perforations. The leader portion cutting line 3 is used to connect the leading end portion of the film leader extension portion 2. By cutting off, the tongue-shaped film leader portion 4 having a narrow width is formed as in the conventional film.

Further, as shown in the figure, the film leader extension portion 2 extends to the front end side from the film leader portion 4, and the extension portion has a sheet portion cutout similar to the leader portion cutting line 3 described above. The line 5 is provided, and the perimeter of the oblong rectangular adapter sheet 6 is formed by the sheet cutout line 5. A window cutout line 7 similar to the leader cutout line 3 is also provided in the central portion of the adapter sheet 6, and the center part of the window cutout line 7 is cut out to obtain a horizontally elongated shape of the panoramic size. A window portion 8 that opens at is formed.

Therefore, a rectangular annular adapter sheet 6 is obtained by cutting out from the extending portion on the front end side of the film leader extension 2 with the sheet cutout line 5 and cutting out the central portion with the window cutout line 7. . Then, the central portion cut out by the window cutout line 7 of the adapter sheet 6 is formed as an information display sheet 9 on which usage information (PP in the figure) of the adapter sheet 6 is printed. The information display sheet 9 also displays information such as the number of recordable films and the sensitivity.

Further, the longitudinal ends 6a and 6b of the adapter sheet 6 are provided with adhesive portions 10a and 10b as adhesive means on the rear surfaces in the figure, respectively, and the rear surface of the information display sheet 9 is also provided. Also, an adhesive portion 10c is provided. These adhesive portions 10a to 10c are made of, for example, double-sided tape having a high adhesiveness to the film material and an appropriate adhesive force capable of being peeled from the surface of the camera body or the like. Further, the adhesive surfaces of the adhesive parts 10a to 10c are protected by a disposable release paper (not shown) that can be discarded.

The shape of the adapter sheet 6 is such that the upper and lower parts are shielded in order to expose the central portion of the original 135 format film format photography to a horizontally long panorama size. The vertical dimension of the portion 7 corresponds to the panoramic size, and the horizontal dimension is about several mm longer than the panoramic size. Further, the longitudinal end portions 6a and 6b of the adapter sheet 6 are provided with a folding streak portion 11 having a plurality of streaks at the upper and lower portions corresponding to the longitudinal end edges of the window portion 7, respectively. Has been.

A procedure for performing panoramic size photography using the thus-configured film in the compact camera 12 as shown in FIG. 2 will be described below. First, the film leader extension 2 on the front end side of the film leader 4 of the film is cut by the leader cutting line 3. Then, the present film has a form similar to a normal 135 type film having the film leader portion 4, as shown in the lower portion of FIG. Next, the adapter sheet 6 is cut out from the film leader extension portion 2 along the sheet cutout line 5, and the central information display sheet 9 is further cut out along the window cutout line 7, and as described above in the center portion. It is possible to obtain the adapter sheet 6 having the window portion 8 that opens in various panoramic sizes.

Since the adhesive portion 10c is provided on the back surface of the information display sheet 9 as described above, the cut information display sheet 9 is a film cartridge as shown by an imaginary line arrow in FIG. 1 can be attached at a predetermined position.

The length of the adapter sheet 6 in the longitudinal direction is slightly shorter than the distance between the pair of running guides in the camera using the 135 type film, and is formed to have substantially the same length. As shown in the upper part of FIG. 2, the adapter sheet 6 is exposed to the film by aligning the longitudinal direction with the film running direction so as to shield a predetermined range above and below the 135 type film photographing area in the compact camera 12. It can be placed in the film exposure opening 14 so that it can be placed between the upper and lower film running guides 13 provided with the opening 14 for the film interposed therebetween, and the up and down direction of the adapter sheet 6 can be set to the running guide 13. Easily positioned. In the film running direction, as described above, the window 8 is formed so as to open to some extent longer than the distance between both edges of the film exposure opening 14 in the film running direction. The adapter sheet 6 may be positioned so that both edges of the film exposure opening 14 in the film running direction face each other, and the adapter sheet can be easily set. Then, one end 6a of the adapter sheet 6 is attached to the flat surface 16 of the camera body on the side of the cartridge chamber 15 using the adhesive portion 10a.

When the space between the film chamber 18 that receives the spool 17 for winding the film and the film exposure opening 14 is narrow, as shown in FIG. It is possible to bend the end portion 6b of the film 6 so as to be along the side wall surface 18a of the film chamber 18 and to attach the adhesive portion 10b of the bent end portion 6b to the side wall surface 17a. In this manner, both ends in the longitudinal direction are attached to both ends of the film exposure opening 14 of the camera body, and the panoramic size photographing adapter sheet 6 is fixed at a predetermined position in the camera.

As described above, the cartridge 1 to which the information display sheet 9 is attached is housed in the cartridge chamber 15 as indicated by the imaginary line arrow in FIG. 3, and the compact camera 12 is loaded with the film. Then, the back cover 19 is closed to take a picture. However, in the case of a model in which the back cover 19 has a film confirmation window 20 as shown in the figure, the information display sheet is displayed from the film confirmation window 20. Various information (PP for displaying panoramic shots, number of sheets, etc.) printed on 9 can be visually confirmed.

When the information display sheet 9 is attached to the patrone 1, the information display sheet 9 is printed at the position of the print information 21 printed at a predetermined position of the patrone 1. The above effect can be obtained by sticking the printed information so that the printed parts match. On the other hand, in the case of a model in which the film confirmation window 20 is not provided, it can be confirmed by attaching the information display sheet 9 to the back surface of the camera body or the like.

In the case of the compact camera 12 of the present embodiment, the end portion 6b of the adapter sheet 6 on the film chamber 18 side is bent and mounted as described above. However, depending on the model, the side of the cartridge chamber 15 must be bent. Some do not, some must both, and some do not. The adapter sheet 6 is provided with folding streak portions 11 at both ends in the longitudinal direction, and can be suitably adapted to either case.
