The outer case 3 has holes for exposing the release button 4, the winding knob 5, the objective side viewfinder window 6, the eyepiece side viewfinder window 7 (see FIG. 3), the taking lens 8, the film counter 9, and the stroboscopic light emitting section 10. And a notch 11 for facilitating pressing of a strobe switch (not shown).

As shown in FIG. 3, the outer case 3 is used to take out the exposed film directly from the unit main body 2.
A part 12 of the back surface is stripped off. A perforation 13 and a notch 15 leaving a tab 14 are provided to facilitate this peeling. When the outer case 3 is removed from the unit body 2 when taking out the film, the perforations 13 and the notches 15 may not be provided. Further, the outer case 3 can be omitted because it is not involved in photographing, and printed paper may be attached to a part of the unit body 2 instead of the outer case 3.

In FIG. 1, the unit main body 2 is composed of a main body portion 20, a front cover 21 mounted before this, and a rear cover 22 mounted after the main body portion 20 after the film is loaded. The main body portion 20, the front cover 21, and the rear cover 22 are integrally formed of plastic.
The main body portion 20 is provided with a photographing lens 8, a shutter mechanism, a film winding mechanism, a film counter 9, a strobe light emitting portion 10, and other necessary mechanisms for photographing.

The main body 20 is provided with a film winding chamber 24 for accommodating a cartridge 23, a film supply chamber 26 for accommodating an unexposed film roll 25, and an exposure frame 27 formed therebetween. ing. In addition, a winding shaft whose lower end is exposed to the outside is provided in the film supply chamber 26,
By rotating the lower end from the outside, the unexposed film may be pulled out from the cartridge and wound around the outer circumference of the winding shaft.

An unexposed film 29 is stored in the cartridge 23 with its rear end fixed to the spool 28. When the cartridge 23 is loaded into the main body 20, the unexposed film 29 is pulled out from the cartridge 23 and rolled into a film roll 25 with the tip 30 inside. The exposure frame 27 is curved to correct the distortion of the taking lens 8, and an exposure opening 27a for guiding the light passing through the taking lens 8 to the film 29 is formed.

The main body 20 is open at its rear surface and the bottom surfaces of the film winding chamber 24 and the film supply chamber 26. In order to shield the back side and the bottom side from light, the rear cover 22 has a back surface portion 22a and a bottom surface portion 22b, and is generally L-shaped. In the rear cover 22, the two engaging claws 32 formed on the back surface portion are inserted into the engaging holes 33 of the main body portion 20, and the engaging hole 35 formed on the bottom surface portion 22b is formed on the bottom portion 20a of the main body portion 20. It engages with the provided engagement claw 34.

The rear cover 22 is provided in the film winding chamber 2
A V-shaped groove 36 is formed in a portion facing 4 and a portion 37 surrounded by the V-shaped groove 36 forms a peelable lid portion 37. A handle 37a is integrally formed on one side of the lid portion 37. When the handle 37a is pinched with a finger and pulled up strongly, the groove 36 is cut and the lid portion 37 is removed, so that a rectangular shape as shown in FIG. The shaped film outlet 38 opens.

Further, the rear cover 22 is formed with an opening 40 through which the winding knob 5 is projected.
0 is provided with a reverse rotation preventing claw 41 that restricts the rotation of the winding knob 5 only in the winding direction. The reference numeral 42 is
Reference numeral 43 denotes a strobe battery, which is a storage unit that stores a strobe device.

As shown in FIG. 6, the film outlet 38
The width D1 of the film is set narrower than the width D2 of the cartridge 23 and wider than the width D3 of the film 29. Therefore,
The film 29 can be pulled out through the film outlet 38, but the cartridge 23 cannot be pulled out. Further, the tip portion 30 of the film 29 is formed with protrusions 30a on both sides thereof, so that the film tip portion 3
The width D4 of 0 is wider than the width D5 of the exit 23a of the cartridge 23.
Does not get caught in the cartridge 23.

The spool 28 is rotatably provided in the cartridge 23, and as shown in FIG. 7, two notches 45 and two ridges 46 are formed in the notch. The upper surface of the ridge 46 is located on the circumference of the spool 28 for winding the film 29 around the spool 28. On the other hand, the height of the claw 45 is equal to or lower than that of the ridge 46. At the end of the film 29, a projecting portion 47 that is inserted between the film 29 and the pair of protrusions 46 is formed, and two holes 48 provided in this projecting portion 47 engage with the claw 45.

When the exposed film 29 is wound into the cartridge 23, the spool 28 is rotated in the direction A in which the claw 45 engages with the hole 48, so that the film 29 is wound around the spool 27 without loosening. On the other hand, when the film 29 is pulled out from the exit 23a of the cartridge 23, the spool 28 is pulled by the film 29 and
Is rotated in the direction. When the spool 28 rotates in the B direction, the claw 45 is in the direction to come off the hole 48, so that the film end portion can be pulled out from the spool 28 without using a cutting means such as a cutter.

Next, the operation of the above embodiment will be described. When photographing, the unit body 2 is kept in the outer case 3. When the release button 4 is pressed, the shutter operates and the photographing light transmitted through the photographing lens 8 is exposed through the exposure opening 2
It is incident on the film 29 located behind 7a. When the winding knob 5 is turned after photographing, the spool 28 of the cartridge 23 is rotated in the A direction via the fork 50, so that the exposed portion of the film 29 is wound into the cartridge 2 and the unexposed portion is exposed. It is set behind the opening 27a. At the time of winding the film 29, the sprocket 49 is rotated by the perforations 29a to charge the shutter and rotate the film counter 9 by one scale. At the same time, the winding stop mechanism is activated to prevent the winding knob 5 from rotating.

When the film is wound by turning the winding knob 5 after photographing the last frame, the film tip portion 30 comes off from the sprocket 49 in the middle thereof. After this,
Since the sprocket 49 is not rotated, winding is not stopped, and the shutter is not charged, so the shutter does not operate even if the release button 4 is pressed. When the winding knob 5 is further rotated a little, the protrusions 30a on both sides of the film tip portion 30 are caught in the outlet 23a of the cartridge 23, so that the winding knob 5 cannot be rotated to wind the film.

The lens-fitted film unit 1 on which all the frames have been photographed is submitted to the photo lab for photographic printing. At the developing station, first, the reverse rotation preventing claw 41 is cut or curved by an appropriate tool to make the winding knob 5 reversible. Next, the tab 14 is pinched with fingers and pulled up, and the part 12 of the outer case 3 is peeled off along the perforations 13. If you pull your finger strongly on the handle 37a,
The groove 36 is damaged, the lid portion 37 is peeled off from the rear cover 22, and a film outlet 38 is formed as shown in FIG. In this state, since the outlet 23a of the cartridge 23 faces sideways, the outlet 23a is directed to the film outlet 38 side as shown in FIG. It should be noted that it is convenient to extend the lid portion 37 to the portion of the unwinding claw 41 so that the unwinding claw 41 can be peeled off from the rear cover 22 together with the lid portion 37.

The leading end portion 30 of the film protruding from the cartridge 23 is pulled out a little more by hand or the like, and then set in the film developing machine shown in FIG. 18, for example. After this setting, the leading end portion 30 of the film is joined to the leader sheet, and then the leader sheet is sent to the developing processing section. At this time, the exposed film 29 is pulled out from the cartridge 23 while reversing the spool 28 and the winding knob 5. Then, the hole 48 formed in the projecting portion 47 of the exposed film 29 is easily disengaged from the claw 45, so that the entire exposed film 29 is pulled out from the cartridge 23 and sent to the developing processing section. The exposed film 29 is developed by this film developing machine and then printed by a photographic printer.

When the exposed film 29 is pulled out,
The film unit with lens 1 has a film winding chamber 2
The empty cartridge 23 remains in the area 4. The lens-fitted film unit 1 is returned to the manufacturer for the purpose of environmental protection and reuse of resources. At the manufacturer, the outer cover 3 is removed from the main body 20 and then the strobe battery 43 is removed. Next, using a tool such as a screwdriver, the holes 35 of the rear cover 22 and the engaging claws 3 of the main body portion 20.
4 and the rear cover 22 is removed from the main body 20. Next, the photographing mechanism attached to the main body unit 20, for example, the shutter, the winding mechanism, the photographing lens 8 and the like is inspected, and when it is determined that there is no abnormality in the photographing mechanism, the main body unit 20 is reused. It

After the main body 20 is returned to the original position, the film counter 9 is returned to the initial position, and then all the parts are supplied to the automatic assembly line together with the new main body. In this automatic assembly line, a new film is loaded in the main body 20, and a new rear cover is loaded after loading the film. Finally, it is packaged in a new outer case and reproduced in a new lens-fitted film unit. The rear cover 22 is melted and used as a molding material for the rear cover and the like, and the strobe battery 43 is discarded.

FIG. 8 shows another embodiment of the unit body. In the unit main body 2, a lid 58 is openably and closably attached to a film outlet 57 of a rear cover 56. A step 59 is provided around the film outlet 57 to enhance the light blocking effect, and a hole 60 is formed on the winding knob 5 side. On the other hand, the lid 58 has
A protrusion 61 inserted into the hole 60, a claw 62 that engages with a recess (not shown) provided inside the rear cover 56, and a handle 58.
a are formed. When the exposed film is pulled out at the developing place, a part of the outer case is stripped off as described above, and then the exposed handle 58a is strongly pulled up.
Since the two claws 51 are disengaged from the holes, the light shielding lid 58 can be removed from the rear cover 56.

In order to prevent the leading edge of the film from being caught in the cartridge 23, the projection 30 is integrally formed with the film 29.
Besides providing a, a rod-shaped clip may be fixed to the tip of the film, or a plastic sheet wider than the film 29 may be bonded to the tip 30 of the film.
Of course, the roll-in prevention member may be omitted so that the film tip portion is completely wound into the cartridge, and in this case, the film tip portion is removed from the cartridge by using a tongue ejector widely known in this industry. Withdraw.

In the above embodiment, the width of the leading end of the film is widened so that the film is not caught in the cartridge. Instead, a film locking member is arranged on the film passage so that the leading end of the film is engaged. You may stop. 9 to 12 show this embodiment, and the same members as those in FIG. 1 are designated by the same reference numerals. A film locking member 65 is arranged beside the sprocket 49. In addition, Patrone 2
In order to reduce the length of the portion not caught in the film 3, the film locking member 65 may be brought closer to the film winding chamber 24 side.

As shown in FIG. 10, the film locking member 65 is engaged with the perforations 29a of the film 29 in a size larger than the perforations 29a so as not to engage with the perforations 29a. The portion 65a and the engaging portion 65a are constantly attached to the film 2
And a spring portion 65b that urges it toward the 9 side. Further, the body portion 20 and the rear cover 22 are formed with recesses 66 and 67, respectively, in which the film locking member 65 is displaced. On the other hand, the openings 30b larger than the perforations 29a are formed on both sides of the film tip portion 30.
Is formed, and the engaging portion 65 is formed in one of the openings 30b.
a enters.

In order to pull out the exposed film directly from the lens-fitted film unit, the film locking member 6
5, a lid portion 71 that can be peeled off by a thin groove 70 is formed. When the grip 71a is held and pulled up strongly, the groove 70 is broken and the lid 71
Is removed to form a rectangular film outlet 72 as shown in FIG. In addition, as shown in FIG.
The outer case corresponding to the lid 71 is provided with perforations for easy peeling.

When the winding knob 5 is turned after photographing, the exposed film 29 is wound into the cartridge 23 as described above. During winding of the film, as shown in FIG. 10, the teeth of the sprocket 49 are perforated 29.
Since it engages with a, the sprocket 49 rotates following the film 29, and the shutter is charged. However, the film locking member 65 is
Since it is larger than 9a, it does not engage it.

After the last frame is photographed, the winding knob 5 is turned to wind the film, and the opening 30b is opened midway.
11 reaches the film locking member 21, the engaging portion 21a enters the opening 24, as shown in FIG. As a result, the movement of the film is blocked, the winding knob 5 cannot be rotated, and the film winding ends when the film tip 30 is slightly out of the exit 23a of the cartridge 23. In this state, the lens-fitted film unit is submitted to the photo lab.

At the developing station, after peeling off a part of the outer case, the exposed grip 71a is strongly pulled up to peel off the lid 71 from the rear case 22. When the lid portion 71 is stripped off, the film front end portion 30 is exposed, so the film is pulled out a little by hand. In this state, it is set in a developing machine and the exposed film 29 is pulled out to perform a developing process. The lens-fitted film unit from which the exposed film 29 has been pulled out is sent to the manufacturer for reuse as described above, with the cartridge 23 stored therein.

By extending the lid portion 71 to the rear surface of the film winding chamber 24, the direction of the outlet 23a can be changed by removing the lid portion 71 and then rotating the cartridge 23. In this case, as shown in FIG. 5, the exposed film 29 can be pulled out in a direction substantially perpendicular to the rear cover and can be set in the film developing machine shown in FIG.

In the above embodiment, a special opening is provided at the tip of the film to lock this portion. However, the notch 30c of the film tip 30 is detected and displaced, and the perforation 29a is locked. You may. FIG. 13 shows this embodiment, and a film locking member 75 having a film detection arm 76 and a claw arm 77 is rotatably provided so as to surround the exposure opening 27a. The film locking member 75 is urged by a spring 78 so that the tip of the film detecting arm 76 contacts the film 29. The film detection arm 76 has a wide width so as not to engage with the perforations 29a, the pawl arm 77 has a narrow width, and a pawl 77a for engaging the perforations 29a is formed at the tip thereof. Further, since the claw arm 77 has a smaller inclination angle than the film detection arm 76, the arm 76 is not attached to the film 29.
The claw arm 77 is in contact with the film 29.
Away from

Normally, since the tip of the film detecting arm 76 is pushed by the film 29, the claw 77a is separated from the film 29. When the film winding end is approached, the film detecting arm 76 enters the notch 30c, and the pawl arm 77 rotates with it.
As a result, the pawl 77a engages with the perforations 29a to prevent film winding. In this embodiment, since the film 29 does not need to be specially processed, a conventional 135 type patrone can be used.

As is clear from the above description, the film locking device shown in FIGS. 9 to 13 can also be used in a conventional lens-fitted film unit in which a cartridge is taken out. Further, in this embodiment, since the film is securely locked immediately before the film winding chamber, it can be used not only for a normal camera but also for a lens-fitted film unit as shown in FIG. 15 which does not use a cartridge. You can

FIG. 14 shows an embodiment using a cartridge capable of sending out the front end of the exposed film by rotating the spool. This Patrone 117
As described in JP-A-2-124564, the exposed film 1 is formed on the outer circumference of a spool (not shown).
Roll up 18 hard. The roll of the film 118 wound on this spool is sandwiched by a pair of flanges on both sides, or the outer periphery of the film roll is pressed by ring-shaped projections.

At the time of taking out the exposed film, a part of the outer cover is peeled off, and then the lid 119 is slid to expose the film drawing port. Next, Patrone 11
7 in the direction of the arrow to turn the outlet 117a toward 9
Change 0 degrees. When the winding knob 5 is rotated in the arrow direction after removing the reverse rotation preventing pawl 41, the spool in the cartridge 117 rotates. With this spool, the film roll rotates together without loosening, and the separation claw (not shown)
The tip of the film 118 separated by
Is sent out from the outlet 117a. After feeding the leading edge of the film, the film is set in the film developing machine and subjected to the film developing process as described above. The lens-fitted film unit from which the film 118 has been taken out is sent to the manufacturer for reuse.

The lid of each of the embodiments shown in FIGS. 1 to 14 is removable or removable, but the lid is integrally formed with the rear cover 22 through the thinned one end, and this one end is formed. It may be swingable around the center. Further, instead of these lids, a sheet having a light-shielding property, for example, light-shielding paper may be used to shield the film outlet from light, and the film may be peeled off or pierced. Further, a film outlet is provided on the side surface of the unit body, and the cartridge is rotated by about 180 degrees so that the exit of the cartridge faces the film outlet, and then the exposed film is passed through the outlet and the film outlet. You can pull it out from.

In the conventional film unit with a lens,
The exposed film is wound into this using a cartridge, which allows the exposed film to be taken out from the lens-fitted film unit in a bright room, and the existing film processing system is used as it is. This is because. However, when the exposed film is directly pulled out from the lens-fitted film unit, it is preferable to omit the cartridge. This will reduce the manufacturing cost, and the user will not be able to take out the exposed film, which will greatly improve the collection rate and allow the lens-fitted film unit to be collected while shooting is complete. It is convenient to use.

FIGS. 15 to 17 show a lens-fitted film unit 79 in which a winding shaft is used instead of the cartridge, and the exposed film is wound around the winding shaft. In the main body 80, on both sides of the exposure frame 81, a film supply chamber 82 for accommodating the unexposed film 85 wound in a hollow roll shape, and a film winding chamber 83 for winding the exposed film 85. Are formed.

Next, the operation of the embodiment shown in FIGS. 15 to 17 will be briefly described. Winding knob 94 after shooting
When is turned, the exposed film 85 is wound around the outer periphery of the shaft portion 96a of the winding shaft 96. At the time of this winding, both side edges of the film 85 are regulated so as not to enter the circular boss 96d of the flange 96c and have a winding diameter larger than a circle connecting the four circular bosses 96d.

After photographing all the frames, the lens-fitted film unit 79 is submitted to the developing station as described above.
At this developing station, the winding knob 94 is rotated to check whether all of the exposed film 85 has been wound around the winding shaft 96, and then the film is taken out.
This can be confirmed from the magnitude of the rotation torque of the winding knob 94, the sound when the film front end separates from the separation claw 106 and hits the rib 98, or the like.

Next, a part of the outer case 115 is peeled off along the perforations so that the portion behind the holding plate 105 is exposed. After folding the reverse rotation preventing claw 111, wind the winding knob 9
When 4 is reversed, the exposed film 85 wound around the shaft portion 96a is rotated together with the winding shaft 96 without being unraveled by the circular boss 96d provided on the flange 96c.

Here, since the notch 110a is formed in the rear end portion 110 of the film, the film is not restricted by the circular boss 96d but protrudes from the flange 96c in a slightly curled state. The protruding film rear end portion 110 moves while being guided by the guide ribs 98. The film rear end portion 110 is hooked by the separation claw 106 and moves toward the film outlet 99. The film rear end portion 110
17 is discharged to the outside of the lens-fitted film unit 79 through the film draw-out port 99 as shown in FIG. 17 while scraping the pile yarns of the teremps 103 and 104.
After this cueing, similarly to the above-described embodiment, the lens-fitted film unit 79 is set in the film developing machine, and all the exposed film 85 is drawn out and supplied to the developing processing section.

After taking out the exposed film 85, the lens-fitted film unit 79 is collected by the manufacturer. As described above, after removing the outer cover 115, the strobe battery 43 is taken out. Next, if a jig or the like such as a driver is inserted from below the engaging hole 90 formed in the rear cover 86 and the pliers are opened, the rear cover 86 is broken along the groove 91, so that it can be easily removed. it can. Since only the portion on which the latch claw 89 is formed remains on the main body 80, this is finally removed. This main body 80
With the front cover 84 still attached, it can be reused as described above, and the rear cover 86 can be replaced with the telemeters 103, 104.
It is taken and then dissolved.

The film outlet 99 may be provided on the side surface of the main body 80. Further, the lower end of the winding shaft 96 may be exposed from the unit main body 80, and the winding shaft 96 may be directly rotated via the exposed lower end. Also, there is one
Instead of using 03, 104, film outlet 9
9 may have a labyrinth structure, or may be provided with an openable / closable lid as described above. In addition, the winding shaft 96
In order to prevent the film roll wound around the film roll from being loosened, an elastic plate that comes into contact with the outer circumference of the film roll is provided, or the guide rib 98 is arranged so as to come into contact with the outer circumference of the film roll. The film roll may be sandwiched between 96c.

Each of the lens-fitted film units described above can be processed by the film developing machine shown in FIG. In FIG. 18, the lens-fitted film unit 79 shown in FIGS. 15 to 17 is set in the film developing machine. The film developing machine includes a film supply unit 12
0, a film reservoir 121, and a development processing unit 122. The film supply unit 120 is a unit loading unit 12 in which a lens-fitted film unit 79 is set.
3, a leader sheet setting portion 125 for setting the leader sheet 124, and a light shielding cover 1 for shielding these
And 26. This light shielding cover 126 is
It is attached to the main body 128 so as to be openable and closable via a hinge 127.

In the unit loading section 123, as shown in FIG.
And a unit holder 136 capable of holding both of the cartridges 135 photographed by the camera. The lens-fitted film unit 79 and the cartridge 135 are first laid out on the film, then joined to the leader sheet 124 via the splice tape 129, and set in the unit holder 136 in this state. The leader tape 124 is sent toward the film reservoir 121 by the perforations 124a formed at the center thereof being engaged with the teeth of the sprocket 130. Further, instead of the sprocket 130, an endless belt having a plurality of claws formed in a line may be used.

In the same way as in the conventional case, the film head of the cartridge 135 is inserted into the cartridge 135 through the outlet 135a and the tip of the film 137 is hooked and pulled out. On the other hand, as described above, the lens-fitted film unit 79 is provided with the reverse rotation preventing pawl 11
The film rear end portion 110 is fed out by folding 1 and then reversing the winding knob 94.

As shown in detail in FIGS. 19 to 22, the unit loading section 123 includes two unit holders 136.
Is provided, and each unit holder 136 is rotatably held by a bracket 138. Each unit holder 136 includes a rectangular plate 139,
A holding piece 140 is bent and formed on both side edges, and the holding piece 140 holds the lens-fitted film unit 79 in a sandwiched state. This pair of holding pieces 14
Since the interval of 0 is slightly narrower than the width of the lens-fitted film unit 79, the lens-fitted film unit 79 is sandwiched between the holding pieces 140.

In this way, since the lens-fitted film unit 79 is sandwiched from both sides, in addition to the basic type, various types such as a built-in flash type, a close-up type, a panoramic type, etc. can be used as in the above-mentioned "Shooting Run" series. Even if there are types, by unifying the vertical length of the film unit with lens for each model, all models can be retained. In this case, it is preferable to form a positioning piece for each model on the plate 139 so that the film extraction port 99 is always held at a constant position for each model. Further, instead of providing the positioning piece, a concave portion or the like for positioning may be provided on the side of the lens-fitted film unit 79 where the holding piece 140 is located.

Below the holding piece 140, a mounting piece 141 for rotatably mounting the unit holder 136 on the bracket 138 is formed by bending. In addition, a cartridge 135 is provided at the center of the unit holder 136.
The patrone locking portion 142 for locking the
It is provided integrally with 39. The cartridge lock portion 142 is composed of a slit 143 for giving a spring property and a curved surface 144 corresponding to the outer peripheral surface of the cartridge 135. When the lens-fitted film unit 79 is loaded, the cartridge lock portion 142 is pushed by this and retracts. The film unit with lens 7
When the 9 is removed, the cartridge lock portion 142 may be positively returned to the original position by using a spring material or the like, instead of being returned by its own elasticity.

The bracket 138 has a mounting screw 147.
It is fixed to the main body 128 of the film developing machine via. A mounting piece 148 is formed on the bracket 138 so as to project therefrom, and two unit holders 136 are rotatably mounted on the bracket 138 via mounting pins 149. A stopper 150 and a coil spring 151 are attached between the unit holder 136 and the bracket 138, and these two unit holders 13
6 is positioned on the bracket 138 in a substantially vertical state.

Sensor mounting plates 154 are formed on both sides of the bracket 138 so as to be parallel to the holding pieces 140. The sensor mounting plate 154 has a film edge detection sensor 155 for detecting the film edge and an initial position detection sensor 156 for detecting that each unit holder 136 has returned to the initial position.
And are arranged. These sensors 155, 156
In the present embodiment, a micro switch is used, and the switch piece 15 obtained by cutting and raising a part of the holding piece 140 is used.
It is turned on and off by 7. A photo sensor or the like may be used instead of the micro switch.

The leader sheet setting section 125 is provided with a sheet setting plate 160 on which the leader sheet 124 is placed. The sprocket 130 and a film feed roller 161 that rotates at the same speed as the sprocket 130 are attached to the sheet setting plate 160. The pinch roller 162 is pressed against the film feed roller 161, and the film is nipped between them. The pinch roller 162 is used for the light shield cover 12
6 attached. As is well known, the cartridge 135 has its film rear end fixed to the spool, so it is necessary to separate this film rear end. Therefore, a cutter 163 is provided at the film entrance 164 corresponding to each unit holder 136. In addition,
In the lens-fitted film unit 79, the film end portion is pulled out from the winding shaft 96, so that the film cutting by the cutter 163 is not necessary.

A film reservoir 121 is provided between the leader sheet setting section 125 and the development processing section 122 to store the film in a loop shape and interrupt the film feeding to the development processing section 122 even during cutting. I try not to be done. This film loop is faster than the film feeding speed into each processing tank of the development processing unit 122.
The film drawing speed of the film supply unit 120 is increased, and the film is formed by the speed difference between them. Further, instead of the storage due to the speed difference, a certain amount of the film may be extracted and stored before the film is supplied to the development processing unit 122, and then the film may be supplied to the development processing unit 122. Further, the film may be collectively pulled out from the cartridge 135 or the lens-fitted film unit 79 to store the entire length of one film.

Next, the case where the lens-equipped film unit 79 and the cartridge 135 are simultaneously developed in the film developing machine will be described. As described above, the film end portion of the film unit with lens 79 and the cartridge 135 are indexed. Next, the leader sheet 124 is joined to the end of each of the cueed films with a splice tape 129.

After opening the light-shielding cover 126 as shown by the chain double-dashed line, the perforations 124a of the leader sheet 124 mesh with the teeth of the sprocket 130.
The leader sheet 124 is placed on the sheet set plate 160. Next, as shown in FIG. 20, the lens-fitted film unit 79 is inserted between the pair of holding pieces 140, and the cartridge 135 is locked to the cartridge locking portion 142.

When the start button is operated after closing the light shielding cover 126, the sprocket 130 and the film feed roller 161 rotate to feed the leader sheet 124 toward the film reservoir 121. As a result, the film discharge port 99 of the lens-fitted film unit 79,
The exposed films 85 and 137 are drawn out from the exit 135a of the cartridge 135, respectively. These films 85 and 137 are stored in a loop in a fixed amount in the film reservoir 121, and then fed to the developing processing unit 122 with the leader sheet 124 as the leading end.

While the film is being drawn out, in the lens-fitted film unit 79, the leading end of the film comes out of the take-up shaft 96, so that all of the exposed film 85 is supplied into the film developing machine. On the other hand, Patrone 135
Then, since the rear end of the film is fixed to the spool,
After all of the film 137 wound on the spool has been pulled out, the cartridge 135 is pulled. As a result, as shown by the chain double-dashed line in FIG. 18, the unit holder 136 uses the pin 149 as a fulcrum and the coil spring 1
It turns against 51. This rotation causes the Patrone 1
The film end detection sensor 155 on the 35 side is turned on, and the rotation of the sprocket 130 and the film feed roller 161 is stopped. During this time, the cutter 163 on the side where the cartridge 135 is locked operates to cut the film 137. After this cutting, the sprocket 130 and the film feed roller 161 rotate again.

In the case of a lens-fitted photo film unit incorporating the same one as the cartridge 135, since the unit holder 136 is rotated at the end of drawing the film, the photo film end detection sensor 155 is turned on. In this case, the cutter 163 operates and separates the film.

The cut empty cartridge 135 drops downward, and the unit holder 136 that holds the cartridge 135 returns to its original position by the bias of the coil spring 151. This return is the original position detection sensor 156.
When it is detected by, the operator is instructed by the buzzer or display to complete the film drawing.

When the drawing of the exposed film is completed,
The operator opens the light-shielding cover 126, takes out the empty lens-fitted film unit 79 and the cartridge 135, and sets a new lens-fitted film unit and cartridge. Of course, two lens-fitted film units or two cartridges may be set in the unit loading section 123. When the light-shielding cover 126 is opened, the sprocket 130 and the film feed roller 161 stop.

The exposed films 85 and 137 sent to the development processing section 122 are sequentially passed through the respective processing tanks for development processing. The film 85 that has passed through each processing tank,
After being dried by a dryer, 137 is accumulated by a well-known film accumulating device in a state where the film is hung for each reader.

The above-described film developing machine can perform not only the film unit with lens without the cartridge but also the film unit with lens using the cartridge 23 shown in FIG. Further, the film end portion is detected by rotating the unit holder, but instead of this, it may be detected by displacement due to horizontal movement. If both the cartridge and the lens-equipped flume unit are of a type in which the film edge is completely removed, the film edge detection sensor and the cutter can be omitted. Further, the unit holder of the above-mentioned embodiment can also be used for a film splicer in which a large number of films are joined to each other to make them long and wound into a roll.

[0076]

As described above in detail, according to the lens-fitted photo film unit of the present invention, the exposed film can be directly pulled out, so that it is not necessary to take out the cartridge from the lens-fitted photo film unit. The take-out work can be greatly simplified.

Further, since the empty cartridge remains in the unit main body, the manufacturer can surely collect both the unit main body and the cartridge.
This can be expected to have a great effect on reuse of parts and environmental protection.

Further, since the end portion of the film is locked in front of the film winding chamber, when the cartridge is used, the work of indexing the film with a tongue ejector is not necessary. If you do not use a patrone,
Since the position of the film end is determined, there is an advantage that the film end is easily pinched in the dark room.

Furthermore, since the exposed film is wound around the winding shaft, the cartridge is not required, and the film winding chamber becomes small, so that the lens-fitted film unit can be miniaturized. Further, since the end portion of the exposed film can be pulled out only by performing the reverse operation of the winding knob, it is easy to find the head of the film. Furthermore, when the reuse of the lens-fitted film unit is taken into consideration, the user cannot take out the film and develop it, so that the recovery rate of the unit at the developing station is improved. In addition, since it is collected by the manufacturer in a state where the inside of the unit body is light tightly shielded, strobe batteries etc.
All parts can be reliably collected, and there is no possibility that dust or the like will enter the unit body during the collection.

Further, since the holder body for holding the lens-fitted film unit is integrally provided with the cartridge holding portion for locking the cartridge photographed by the camera, the holder body is not limited to the lens-fitted film unit. In addition, the patrone can be set selectively.
Therefore, it is not necessary to sort the lens-fitted photo film unit and the cartridge, so that the developing work can be performed while these components are mixed. Furthermore, since the holder main body is provided so as to be displaceable in the film feeding direction, the film end can be easily detected by detecting this displacement. Moreover, when the film can no longer be pulled out, the cutter cuts the film, so it can be automatically used for conventional film cartridges with the film end fixed to the spool, and for the lens-equipped film unit loaded with this film cartridge. Can be developed.
