Abstract

PURPOSE:To facilitate the detachment of a winding chamber after photographing has been ended, and also, to executing development by a general-purpose processor as it is, by providing a narrowed part for detachment between the winding chamber and an exposing chamber of a camera body. CONSTITUTION:As for a detaching part 12 of a dispasable camera, a constricted part 17 is formed by leaving a thin thickness part 16 in a film passage 15 from the body surface side between a winding chamber 13 and an exposing chamber 14, and also, a thin thickness part 18 is formed on the reverse side, as well. To the respective inner surfaces of the thin thickness parts 16, 18, a light shielding member 19 is stuck, and on the outer a detachment notch 20 is provided surface. After photographing all frames of a film has been ended, the winding chamber and the exposing chamber can be detached easily, and the winding chamber makes no great difference from a usual cartridge as to its external form and can be set to a general-purpose processor as it is, and also, even if the detachment is executed in a bright room, no exposure occurs due to the light shielding member.

理できない不便さが考えられる。-a) After this type of camera finishes taking pictures of all the frames of the film, the camera itself is destroyed and the film inside is taken out when developing the film, so the camera body is disposable after each use. Conventionally, such cameras have used film cartridges containing 1) type 0 or type 126 film, but it is not easy to break the camera and remove the cartridge. Also, currently 135
Although there is no type 135 cartridge, if a 135 type cartridge were to appear, 1) if it is similar in shape to a type 0 cartridge, it would still have the above drawbacks, and The type of film cartridge is regular 35 Tsuru film.
(Roll film J135 [JIS 7519) cannot be processed in a general-purpose processing machine that is compatible with cartridges (JISK 7528) containing J135 [JIS 7519], and can only be processed at a special processing laboratory equipped with a processing machine for such cartridges. There may be inconveniences in not being able to do so.

な大きさとしである。The front side 1) a and the back side 1) b can be joined together at each contact point including the side of the winding chamber 13, or by gluing the overlapping portions, as shown in FIG. Reference numeral 12 denotes a separation portion of the camera body 1). As shown in the second figure, the separation section 12 is formed between the winding chamber 13 and the exposure chamber 14 of the camera body 1), leaving a thin section 16 in the film passage 15 from the surface side 1) a of the camera body 1). In addition to forming the thin wall section 17, a thin wall section 18 is also provided on the wall surface of the back side 1)b of the camera body 1) which the thin wall section 16 faces. Part 16
．． The winding chamber 13 can be easily separated from the winding chamber 18 as shown in the third figure. In the embodiment, the winding chamber 13 is
1) The shape is the same as that of the film cartridge system, and the dimensions are such that it can be installed in a separated state in a current automatic processing machine.

The groove 20 is provided to make the cutting easier and to define the cutting position. Therefore, as shown in FIG. 4, if the groove 20 is provided closer to the exposure chamber 14 than the attachment part of the light shielding members 19a and 19b, the light shielding member 19a and
19b is ensured to remain, which is preferable. However, when pasting the light shielding members 19a and 19b, glue is applied only to the winding chamber 13 side, and the concave groove 20 is placed closer to the exposure chamber 14 than the glued area.
A similar result can be obtained even if .

ようにすることが望ましい。Although AS resin, methacrylic resin, and acrylic resin are superior in terms of price, strength, and brittleness when folded,
There is no need to limit it to this. Izot impact strength is one of the measures of ease of breakage. For example, in the case where the grooves 20 are provided in both of the thin parts 16 and 18 as described above, the thickness l at the thinnest part is set to 0.
Approximately 20 kg-cm/cm at 8 am
It can be said that the resin that breaks below is easy to break. The Izot impact strength value, which is the standard for breakability, differs for each resin, so if you want the thickness of the thinnest part to be Jt < Jt, use a resin with a smaller value, and if you want to make it thinner, use a resin with a larger value. It is desirable to use resin so that it can always be separated with a constant force.

第５図〜第７図は前記切り離し部１２を極めて切り離し
易く形成した場合の仮補強手段の代表例を示している。FIGS. 5 to 7 show typical examples of temporary reinforcing means when the cut-off portion 12 is formed to be extremely easy to cut off.

いる。ε Although the shape of the winding chamber shown here is different from that of the previous embodiment,
It goes without saying that the size has been devised so that it can be handled on a par with 35mm cartridges. The case shown in FIG. 5A is an example in which a temporary reinforcing member 21 made of a resin molded product is applied to the camera body 1) so as to be perpendicular to the narrowed portion 17, and in this case, an exposure window is provided on the front side of the camera body 1). A hole is made in the corresponding part so as not to block the hole 22. This temporary reinforcing member 21 may go around the camera body 1);
In the example shown in FIG. 1, the camera body 1) is constructed so that it can be hooked from the front surface to the side surface and hooked to the end portion of the back surface using hooks 21a and 21b.

1 is applied to the camera body 1), and in this case as well, the temporary reinforcing member 21 is rotated from the front surface of the camera body 1) to the upper and lower sides and hooked to the upper and lower ends of the back surface with hooks 21a and 21b. It consists of

も可能である。FIG. 7 shows ribs 23, 23 whose upper edges are bent outward along the edge of the narrowed part 17, and a temporary reinforcing member 21 with a groove 21' capable of holding the ribs 23° 23, which has elasticity. This is an example of using it to slide it in. In this example, in order to make the explanation easier to understand, the rib 23 is shown to protrude from the camera body by a considerable distance, but it is desirable to make the amount of protrusion small so that the folded portion can be directly applied to a general-purpose developing machine. Of course, it is also possible to form a groove on the main body side, form the temporary reinforcing member in a U-shape, and fit it into the groove.

If you directly connect one end of the camera (see explanation of the figure) to the winding shaft without any trouble to the winding operation, and removably connect it to the winding shaft from the outside of the camera body,
Camera body 1) is preferable in terms of making the camera itself more compact. 2

最低限の機構が組込まれていることは勿論である。Although not specifically explained in the above embodiment because it is not directly related to the invention, it goes without saying that the minimum mechanism necessary for photographing is incorporated in the camera body 11.

を係脱可能にしておけば、その不都合さも解消できる。In the above embodiment, when a predetermined number of frames have been photographed, for example, all the film is stored in the winding chamber and the winding chamber 13 is folded away from the separation part 12. It will be separated more easily than other parts. Of course, if the structure is such that the other end of the film wound in the storage chamber on the opposite side of the winding chamber 13 is glued to the shaft, the length of the film should be made as long as necessary in advance. Therefore, even if the winding chamber is separated, the shooting screen will not be damaged. In this case, the work of cutting the film with scissors is required, but this inconvenience can be overcome by making the relationship between the shaft inside the storage chamber and the end of the film detachable.

る。Even if this separation work is done in a bright room, there is no problem because a light-shielding material is attached to the separation part of the winding chamber 13, making it light-tight. Now you can take it to the photo lab.
