BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film unit with a lens (film-integrated camera) which has been loaded with an unexposed roll-shaped photographic film in advance and has an exposure function for photographing, and more particularly to an outer box thereof. .

[0002]

BACKGROUND OF THE INVENTION Film units with a lens have become widespread as a convenient device for photographing when a camera is not carried. This is a device in which an unexposed film containing a patrone is previously loaded in a dark box-shaped main body provided with a photographing lens and a shutter, and is widely marketed at a film store or the like.

[0003] The film unit with the lens, after taking a picture, requests development to a film unit and a print development laboratory in a state where the film is built in. At the developing station, the photographed film is taken out from the film unit and subjected to a developing process. Then, the film unit main body is discarded or partially recycled for use in a developing laboratory.

Conventionally, in order to provide this film unit with a lens at low cost, a photographic lens and a simple shutter are mounted on a plastic molded unit main body, and a film and a cartridge are built in. The unit body is housed in an outer box made of cardboard or the like.

[0005]

When a photographed film is taken out of the above-mentioned film unit with a lens in a developing laboratory, the outer box must first be broken to expose the unit body.

In order to process a large number of film units quickly, it is necessary to make the time-consuming operation of removing the unit body from the outer box more efficient.

On the other hand, the unit body from which the film is taken out is discarded or partially reused together with the outer box.

[0008]

According to the present invention, there is provided a lens-equipped film unit having a back cover for taking out a photographed film from a unit body, without removing the unit body from an outer box. An object of the present invention is to provide a lens-equipped film unit which can be opened to easily take out a film from a unit body.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a film unit with a lens according to the present invention.

FIG. 1 is a front perspective view showing the appearance of the film unit with a lens. The unit main body 10 is largely covered by an outer box (carton) 30.

FIG. 2 is a front perspective view showing a state where the unit main body 10 is pulled out of the outer box 30.

FIG. 3 is a rear perspective view of the film unit with the lens, and FIG. 4 is a rear perspective view showing a state where the unit main body 10 is pulled out of the outer box 30.

The unit main body 10 is composed of a front cover, a main body, a back cover, and the like, and each is molded from plastic or the like, and is further assembled by attaching a lens and a shutter. Further, after the unexposed film and the film take-up and storage patrone are loaded at predetermined positions, the back cover is closed to complete the lens-fitted film unit. The back cover is connected to a part of the unit main body 10 so that the unit cannot be reloaded with the film after the taken-out film is taken out, so that the back cover is broken when the film is taken out.

On the front side of the unit body 10, a photographic lens 12, a finder window 13,
A strobe light emitter 14, a shutter release button 15, a film counter window 16, and a strobe charging pilot lamp 17 on the top side, and a film winding knob 1 on the back side
8, a finder eyepiece 19 and a back cover 20 are provided.

The outer box 30 is formed by folding and bonding thick paper or the like to form a book case. The unit main body 10 can be inserted through one large opening 31. In addition, through holes are formed at appropriate positions in the outer box. The lens mount 11, the finder window 13, the strobe light emitter 14, the film counter window 16, the strobe charging pilot lamp 17, the finder eyepiece 19, and the like are exposed from these through holes.

At the upper and lower ridges, which are part of the outer box 30 and near the opening / closing boundary between the unit body 10 and the back cover 20, easy break opening means 32A and 32B such as perforations are provided. is there. The perforations 32A and 32B are formed from the opening 31 to about half the depth of the outer box 30. This is to remove the patrone 21 containing the photographed film from the patrone storage room of the unit main body 10, insert the tip of a driver etc. into the gap between the back cover 20 and the unit main body 10, and half open it as a rod, Further, a perforation length necessary for taking out the patrone 21 after the back cover 20 is bent at a bent portion at a predetermined position and broken into two parts is set. When the entire back cover 20 is taken out from the unit body 10, the perforations 32A and 32B are formed over the entire length of the back cover 20.

FIG. 5 shows the developed shape of the outer box 30.

The hole diameters and pitches of the perforations 32A and 32B are appropriately determined by the strength of the thick paper of the outer box 30, the setting of the opening force, and the like. The resistance of the perforations 32A and 32B is set to a range that does not allow the user to easily open it due to abrasion or the like during use and that the user does not open the back cover by opening force.

The operation of the thus-configured film unit with lens will be described below.

(1) When developing a photographed film, the entire film is first wound into the cartridge 21.

(2) The perforations 32A and 32B of the outer box 30 covering the unit body 10 are cut open. Alternatively, use the tip of a tool such as a screwdriver to
Are disengaged, and the perforations 32A, 32B are simultaneously separated by the force for opening the back cover 20. FIG. 6 is a perspective view showing a state in which the back of the outer box 30 is cut out from the perforations 32A and 32B and the back cover 20 is exposed.

(3) FIG. 7 shows the outer box 30 with perforations 32A and 32B.
FIG. 4 is a perspective view showing a state where the back cover 20 has been cut away from the back cover 20 and a part of the back cover 20 has been removed therefrom. The back cover 20 is raised by using the tip of a tool such as a screwdriver at the engaging portion 22 between the unit body 10 and the back cover 20, and the back cover 20 is further separated to expose the cartridge housing chamber 23.

(4) In this state, the patrone 21 can be taken out of the patrone accommodating chamber 23. The photographed film stored in the cartridge 21 thus taken out is sent to the next developing process.

FIG. 8 is a perspective view showing another embodiment of the outer box according to the present invention. In this embodiment, the perforations 33A and 33B provided on the upper and lower ridges are continuously struck with a predetermined distance L from the edge of the opening 31. This prevents the user from inadvertently cutting the perforations of the outer box 30 during use.

In the above-described embodiment, the perforation is described as the easy-break opening means. However, the present invention is not limited to this, and a means such as a herringbone cut portion or a tear tape may be used.

[0031]

As described above, according to the film unit with the lens according to the present invention, by cutting along the opening means such as the perforation near the opening / closing boundary of the back cover of the outer box covering the unit body. Since the back cover is easily exposed, opening the back cover and taking out the patrone is easy,
Workability during development of the film unit is improved.

In addition, in the case where the used outer box is quickly removed from the unit body and discarded, and the unit body is taken out and reused, the efficiency of the sorting operation is increased.

Further, since the cutouts such as perforations are formed in the outer box, the outer box production process is easy and the cost does not increase.
