Reference numeral 3 is a printing device for printing frame numbers and film types, 104 is a pressing roller for pressing the film against the guide roller 101, and 105 is a cutter.

First, the formation of the unexposed film roll F will be described.

A long unexposed film F0 having perforations formed along both side edges is wound around a frame 100, and the long unexposed film F0 is fed from here through some guide rollers 101 to form a film roll forming machine. At 102, the long unexposed film F0 is wound up. Further, in the long unexposed film F0, a frame number or the like is printed near the side edge of the film by the printing device 103 during winding. The wound long unexposed film F0 is cut by the cutter 105 with its slightly trailing end pressed against the guide roller 101 by the roller 104. At this time, an engagement hole Fb that engages with a protrusion provided on the spool 107 described later is also formed.

Next, the film roll forming machine 102 will be described with reference to FIGS. 2 is a perspective view of the film roll forming machine 102, and FIG. 3 is a sectional view taken along line AA of FIG.

The film roll forming machine 102 has a collet chuck 102a which can be divided into three parts in the longitudinal direction, and a casing 102b which supports the collet chuck 102a. One piece 102a1 of the collet chuck 102a which is divided into three parts has flexibility. A leaf spring 102c having a groove is fixed. The tip of the leaf spring 102c is bent along the surface of the collet chuck piece 102a.

The collet chuck 102a is the casing 1
When the rod advances and retreats in the axial direction inside 02b, the rod interrupts collet chuck 102a and the three-piece pieces are separated from each other.
2a1, 102a2 and 102a3 are integrated.

Therefore, in order to wind the film, as shown in FIG.
As shown in FIG. 3, the front end of the long unexposed film F0 is shown in FIG.

Is cut by The long unexposed film F0 wound up and cut is referred to as an unexposed film roll F.
Unexposed film roll F to collet chuck 102a
To remove the unexposed film roll F, if the diameter of the collet chuck 102a is reduced while the periphery of the unexposed film roll F is held by the holding means so that the unexposed film roll F does not become loose, It can be removed more easily than F.

If the collet chuck 102a is removed after the unexposed film roll F has been loaded into the film roll chamber described below and before the attachment of the light shielding member,
It is also possible to give the film roll chamber the function of a holding means.

Next, a method of attaching the unexposed film roll F to the spool 107 will be described with reference to FIG. FIG. 4 is a perspective view when the unexposed film roll F is attached to the spool 107.

A spool 107 is attached to the free end of the unexposed film roll F which has been wound up and cut from the long unexposed film F0 by the cutter 105. This attachment is performed by the long groove 107a of the spool 107.
A protrusion (not shown) is formed inside the
The free end Fa of the unexposed film roll F is inserted from a and the hole Fb formed in the free end Fa of the unexposed film roll F is engaged with the protrusion inside the long groove 107a. This method can be performed without using other parts and is the most preferable method. Alternatively, a tape may be used to attach the free end Fa of the unexposed film roll F to the spool 107 by attaching it. It is possible.

The spool 107 to which the free end of the unexposed film roll F is attached is the cartridge body 108.
Is inserted into. This step will be described with reference to FIG.

FIG. 5 is a perspective view of the cartridge before assembly.

Reference numeral 108 denotes a cartridge body, which is formed in a cylindrical shape and has an opening portion 108b whose one end is closed by a first lid 108a and the other end is opened. A slit 108d is provided in the slit 108c serving as a film entrance / exit so that unnecessary light does not enter. At the time of manufacturing the film unit with a lens, such a cartridge body 108 is prepared.

The spool 107 to which the free end portion Fa of the unexposed film roll F is attached is inserted into the cartridge body portion 108 through the opening portion 108b, and at the same time, the unexposed film roll F is also inserted through the slit 108c.

Thereafter, the second lid 109 is attached to shield the opening 108b and the cartridge body 108 is kept in a light-tight state, whereby the cartridge C is completed.

Next, the process of loading the cartridge C into the lens-fitted film unit body will be described with reference to FIG.

As for the completed cartridge C and unexposed film roll F, the cartridge C is in the cartridge chamber 110b of the lens-fitted film unit body 110, and the unexposed film roll F is the lens-fitted film unit body 11
No. 0 film roll chamber 110a, and a back cover 111, which is a light-shielding member, is attached to the inside of the film unit main body 110 with lens, that is, between the film roll chamber 110a, the cartridge chamber 110b, and between the film roll chamber 110a and the cartridge chamber 110b To make the film passage of the light tight state.

The light-shielding member mentioned here is a member fixed to the lens-equipped film unit body 110 at the end of the process in order to shield the lens-equipped film unit body 110 from light, and is integrated with the back cover. When the openable and closable door-shaped member is finally fixed, the door-shaped member serves as a light shielding member.

The manufacturing of the film unit with a lens is completed as described above.

In the method of manufacturing a film unit with a lens as described above, the other end of the long unexposed film F0 is wound around the collet chuck 102a and formed into a roll to complete the cartridge C as described above. I went before. This method is advantageous in terms of space efficiency and the like when considering automatic manufacturing by a machine.

As another method, the other end of the long unexposed film F0 may be wound around the collet chuck 102a and formed into a roll shape after the cartridge C is completed. . That is, one end of the unexposed film roll F is engaged with the spool 107, the spool 107 is inserted into the cartridge body 108, and the opening 108b is shielded by the second lid 109 to complete the cartridge C. After that, the other end of the unexposed film roll F may be wound around the collet chuck 102a and formed into a roll shape. In addition, one end of the unexposed film roll F is engaged with the spool 107, and the other end of the unexposed film roll F is collet chucked immediately after being inserted into the cartridge body 108 and before the second lid 109 is mounted. It can also be wound around 102a to form a roll.

As another method, instead of winding the unexposed film roll F on the collet chuck 102a, a take-up spool is prepared for each unexposed film roll and the film is wound on the take-up spool. It is also possible to load the unexposed film roll together with the take-up spool into the unexposed film roll chamber.

Further, instead of winding the film in an exposed state, a light-shielding member having a shape like the cartridge C may be prepared and wound in the light-shielding member. In this way, the film can be loaded into the lens-fitted film unit body 110 even in a bright room.

Furthermore, in the above-described embodiment, when the spool 107 is inserted into the cartridge body 108, the spool 107 is inserted from below in FIG. 1, but the second lid 109 is previously attached to the cartridge body 108. Then, the first lid 108
The reverse method may be adopted in which the a is removed and the first lid 108a is attached after the insertion from the upper side in FIG.

Further, after preparing the cartridge body 108 with both ends open, the spool 107 having one end of the film attached is inserted into the cartridge body 108, and then both ends of the cartridge body 108 are covered with the first lid. 108
Alternatively, the cartridge C may be completed by being shielded by the second lid 109.

Further, in the embodiment described above, the opening 108b of the cartridge body 108, which is closed at one end and opened at the other end, is shielded by the second lid 109, but this second lid is used. For example, 109 can be integrally formed with the back cover 111. In this case, the cartridge body 108 whose one end is open is placed in the cartridge chamber 110b, and the unexposed roll film F is stored in the film roll chamber 110.
After being put in a, the back cover is attached to the lens-equipped film unit main body 110, so that the cartridge is completed and at the same time the unit main body is shielded from light.

As described above, when the second lid 109 is provided integrally with the back lid 111, the second lid is connected to the back lid via the thin portion, and the film unit with lens is used for photographing. When taking out the finished film, the second lid is separated from the back lid so that the second lid can be taken out integrally with the cartridge. By doing so, it is possible to prevent the reuse of the back cover once used.

Next, an embodiment in which a leader portion which is a film connecting member is connected to the spool in the cartridge, the leader portion is taken out from the completed cartridge, and the leading end of the unexposed film roll is connected to the leader portion. Will be described below.

7 and 8 are views for connecting the leader portion in the cartridge and the leading end of the unexposed film roll.

In FIG. 7, the leading end of the film F1 pulled out from the unexposed film roll F is attached to the cartridge C.
It is connected to the leader portion L protruding from the adhesive tape 121.

Further, in FIG. 8, the locking portion F is attached to the leading end of the film F1 pulled out from the unexposed film roll F.
2 is provided, and the engaging portion F2 is inserted into the engaging hole La provided in the leader portion L and connected.

Next, FIG. 9 to FIG. 11 show three forms for connecting the leader portion L and the spool 107.

In FIG. 9, the leader portion L and the spool 1
07 are connected by the adhesive tape 122.

In FIG. 10, the engaging portion Lb at the tip of the leader portion L formed like the free end portion Fa described in FIG.
Is inserted into the long groove 107a provided on the spool 107 and locked.

In FIG. 11, FIG. 11A is a perspective view,
FIG. 11B is a sectional view, and the spool 207 and the leader portion 207a are integrally molded.

The film F drawn from the unexposed film roll F and the leader section shown in FIGS.
1 may be connected by an adhesive tape 121 as shown in FIG. 7 or, though not shown, as shown in FIG.
You may provide and connect.

As described above, by using the cartridge having the leader portion, the process of assembling the cartridge is a process different from the process of loading the unexposed film roll on the film unit body with lens, so that the process is simplified, Moreover, the cartridge assembling process can be performed in a bright room.

Further, as shown in FIG. 12, if a light shielding sheet member 300 of a predetermined length made of light shielding paper or the like is connected to the tip of the unexposed film roll F and the unexposed film roll is wound. It is also possible to load the unexposed film roll F into the film unit body with a lens in a bright room. The predetermined length means a sufficient length such that the end of the light-shielding sheet 300 can be connected to the spool of the cartridge without exposing the unexposed film roll F. Further, in this case, as shown in FIG. 12, the unexposed film is wound around a spool integrally formed with collars 311 and 312 on both sides so as to form a film roll. Prevents film exposure due to light from the end faces in the direction.

Further, the light-shielding sheet member 300 may be a non-exposed film roll F coated with light-shielding paint on the tip thereof.

[0058]

According to the present invention described in claims 1 to 22, the film winding is not performed twice as in the conventional case, and
Since it only needs to wind the film, the cost can be reduced by drastically reducing the number of winding steps, and the occurrence of scratches on the film surface is halved, so a reliable film unit with a lens can be realized. .
