Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a camera for taking a photograph on an instant 1, which can obtain a color print 1- or a black and white print on the spot where the photograph is taken. The present invention relates to an instant camera in which parts of the camera, such as photographing optical system parts, are stored and transported.

[Conventional technology]

With instant photos, you can get color or black and white prints on the spot, so you can check the print status on the spot, respond to urgent reports and news reports, or determine the appropriate exposure using exposure tests. The purpose of use is different from that of regular photos.

Therefore, this instant photographic film has 35
This film is a film that is close to the print size of a normal type, which is larger than an nwn format negative film, and an appropriate number of films are stored in a pack, and this film pack is loaded into a camera for instant photography, that is, an instant camera. . When the film is released, the top layer of film in the film pack is exposed, and a developing roller driven by an electric motor spreads and develops the film as it is sent out of the film pack to the outside of the camera, resulting in a print. will be obtained. Due to the circumstances described above, instant cameras generally have large film packs and use long focal length lenses, resulting in a bulky shape that is inconvenient for carrying.

Therefore, in order to make the camera compact and bulky when carrying it around, there is a camera that has a part of the camera body that can be folded.

[Problem that the invention seeks to solve]

In the conventional instant 1 camera described above, in which a part of the body can be folded, the folding operation is performed manually. It is conceivable to use a motor to do this, but in the conventional case, in addition to the motor for transporting the film, a motor for performing the two-part folding operation had to be built in, which would increase the weight and In order to provide a space for housing the motor, the camera becomes larger.

Therefore, the present invention provides an instant 1 camera in which a part of the main body, such as a photographic optical system, can be appropriately stored in the main body, and this storage operation and film feeding are performed by one motor. is intended to provide.

[Means for solving problems]

In order to achieve the above object, an instant camera according to the present invention has a mechanism that feeds the film out of the camera body after the release, and a part of the camera is placed at a shooting position used for shooting during shooting, and a part of the camera is placed at a shooting position used for shooting when shooting In an instance 1 to camera that sometimes has a storage mechanism in the camera body, a power transmission path for the film feeding operation system and a power transmission path for a part of the camera storage operation system are set up, and these power transmission paths are set up. The present invention is characterized in that by switching the transmission path and using it, one motor can perform both the film feeding operation and the retracting operation of a part of the camera.

[For production]

When the camera is used for photographing, a knob or the like is operated to switch the power transmission path to the photographing operation system, and a switch or the like is operated to move the motor. This places a part of the camera at the photographing position.

When the motor rotates in response to the release, the power transmission path is switched to the film 11 delivery system, and the photographed film is delivered to the outside of the camera.

When the camera is not used for photographing, a part of the camera is stored in the camera body by operating a knob or the like to switch the power transmission path from the sending operation system to the retracting operation system and rotate the motor.

The operation of positioning and retracting a part of the camera to the photographing position can be performed in conjunction with the movement of the motor using a main switch provided on the camera.

The operation of the instant camera 1 according to the present invention configured as described above will be explained below.

The state shown by the solid line in FIG. 2, FIGS. 3, 5, 7, and 9 show the state in which the photographic lens unit 19 is stored in the main body case 4, and in this state, this instant 1-camera is Since it cannot be used for photography, it is kept compact so that it can be conveniently carried around.

In this state, as shown in FIG. 9, the tip of the actuating lever 81 is located forward of the lens frame 18, and the lower surface of the tip engages with the upper surface of the protrusion +8a of the lens frame 18. For example, if the photographer uses the photographic lens unit 19
Even if I try to pull it up in the negative direction, I can't pull it up. Further, since the actuation lever 81 is at the forefront, the locking protrusion 82d of the control member 82 is pushed by the locking projections 8 and e of the operation lever 81, so that the control member 82 is also at the front.

At this time, the stopper protrusion 82e of the control member 82 is located within the rotation range of the stopper pin 9 implanted in the swing arm 34 of the planetary gear train 32, and the swing arm 34 is moved from the position shown in FIG. Rotation is rotation in the counterclockwise direction.

Further, the sector-shaped first gear 45 and the sector-shaped second gear 46 are in the position when the slider 10 is positioned at the rearmost position, and the encoder 85b outputs the position of the sector-shaped gears 45 and 46.

Further, the mirror 17 is tilted to a nearly horizontal position as shown by the broken line in FIG.

In order to change the camera from the stored state at the storage position P described above to the standby state, which is the photographing position P2, where the camera is used for photographing, operate the operation lever part 83b of the switching operation lever 83 as shown in FIG. The switching operation lever 83 is rotated from the position shown in FIG. 10. Therefore, the input lever 83c of the switching operation lever 83, which is engaged with the locking pin 81f of the operating lever 81, turns counterclockwise in FIG. 9 to move the operating lever 81 to the position shown in FIG. make them retreat. As a result of this retreat, the engagement between the tip of the actuating lever 81 and the protrusion 8a of the lens frame 18 is released, allowing the photographing lens unit 1-19 to move upward.

Further, when the actuating lever 81 is moved backward, the actuating lever 81
The control member 8 that was restrained by the locking protrusion 81e of
2 becomes free, and the control member 82 also retreats due to the restoring force of the return spring 82c. Therefore, the stopper protrusion 82e of the control member 82 retreats from the rotation range of the stopper pin 9 implanted in the swing arm 34, so that the swing arm 34
Figure 0” - Rotation in the counterclockwise direction is allowed.

Simultaneously with the retraction of the operating lever 81, the switching operation lever 8
The switching lever 83d of No. 3 is the switch piece 84 of the switch 84.
a to turn on the switch 84.

'' The output of the encoder 85b indicates that the operating lever 81 is at the rearmost position, and the electric motor 3 rotates in the forward direction based on this information and the change of the switch 84 from OFF to ON. This forward rotation of the electric motor 3 causes the pinion gear 21 to rotate counterclockwise in FIG. 9. When the rotation of pinion gear 21 is transmitted to sun gear 33 via gears 22 to 31, sun gear 33 rotates clockwise in FIG. 9. Since an appropriate frictional force acts between the sun gear 33 and the swinging arm 34, the swinging arm 34 also rotates in the same direction, and the planetary gear 35 pivotally supported by it meshes with the first gear 41. I will do it. Therefore, the rotation of the electric motor 3 is transmitted from the planetary gear 35 to the fan-shaped first gear 45 via the first gear 41, the second gear 42, the third gear 43, and the immediate gear 44. The sector-shaped first gear 45 rotates clockwise in FIG. 9.

As shown in FIGS. 17 and 18, a sector-shaped second gear 46 is attached to the sector-shaped first gear 45, and a recess 45d of the sector-shaped first gear 45 and an engagement pin 46d of the sector-shaped second gear 46 are engaged with each other. Since they are combined in the same state, the fan-shaped first gear 4
5'' rotation causes the fan-shaped second gear 46 to also rotate clockwise in FIG. 9.

The fan-shaped second gear 46 has a rack 1 of the slider 10. Oa
Since these are in mesh, the slider 10 will move forward from the position shown in FIG. 9 to the position shown in FIG. 10.

Since the lower end of the quick-acting link 11 is connected to the guide pin [Oc] implanted in the slider 10, the lower end of the link 11, which moves as the slider 10 moves forward, moves forward as well. . On the other hand, since the lower end of the driven link 12 is rotatably supported by the side plate 4a, the distance between the lower end of the driving link 11 and the lower end of the driven link 12 is changed by the forward movement of the quick-acting link 11 described in 1. It will be shorter.

Therefore, the upper ends of the instant link 11 and the driven link I2 are pushed upward. At this time, the pin 1.2a at the upper end of the driven link 12 slides in the elongated hole 1.3a formed in the top plate 3, and connects the shaft between one end of the driven link 12 and the top plate 13. The distance from one end of the supported and immovable drive link 11 to each link]
The distance between the lower ends of 1.12 becomes shorter.

Since the top plate 13 is attached to the upper end of the link 11.12, the top plate 13 is also pushed upward, and the lens frame 18 provided at the front end of the top plate 13 is pushed upward.
will rise. Since the photographing lens units 1 to j9 are provided in the lens frame portion 18, the photographing lens units 1 to 19 are raised by 1 and are located at the photographing position P2 where they can be used for photographing.

Furthermore, since the mirror cover 16 is supported at the rear end of the top plate 13, the mirror cover 16 also rises as the top plate 3 rises. At this time, since the operation plate 15 is pivotally supported at one end of the driven link 12, the operation plate 15 is also supported.
Since the pin 16b of the cover guy 1 implanted in the mirror cover 16 is loosely inserted into the elongated hole 15a of this operation plate 15, the mirror cover 16 is raised only when the operation plate 15 is raised. This will be guided by. Therefore, after being raised, it is in an appropriately inclined state as shown in FIG.

A mirror guide pin] 7b installed horizontally on the mirror 17 is loosely inserted into the elongated hole 15b of the operation plate 15, so that as the operation plate 15 rises, the mirror 17 moves around its rotation axis 17a. It rotates counterclockwise in FIG. 9 about , and is positioned at an appropriately inclined position as shown in FIG. 10. In this case, the rotation angle of the mirror 17 is guided by the rise of the operation plate 15. Then, in this state, mirror 1
If there is a photographing lens 7, the film 71 can be exposed through reflection by the mirror 17 through 9a;
That is, the camera enters a standby state in which it can be used for photographing.

Further, when the slider 10 slides to the frontmost position to put the camera in the standby state, the lock member 61 is engaged with the lock recess formed in the lock portion]Od of the slider 10, as shown in FIG. Stop arm 61. The locking pin 61e implanted in b is engaged with the locking pin 61e. This is because when the slider 10 moves forward, the locking pin 6]e scrapes the lower surface of the lock portion 10d due to the restoring force of the return spring 61f, and when the locking pin 6]e is located at the lock portion 4]Oe, the locking member 61
This is because the locking pin 61e is rotated counterclockwise in FIG. 9 about the shaft 6]d, and the locking pin 61e falls into the locking recess 10e.

Furthermore, when the locking member 61 rotates, the release arm 61a also rotates counterclockwise in FIG. Lever G2 becomes free. The rear end of a locking lever 63 is engaged with the other end of this communication lever 62, and since the communication lever 62 becomes free, the restraint of this locking lever 63 is released. Moreover, since the restoring force of the tension spring 63c is applied to this locking lever 63, the locking lever 63 receives this restoring force and moves in the direction of arrow P in FIG. It will rotate to. This rotation causes the notch 63b formed at the front end of the locking lever 63 to engage with the guide pin llb of the drive link 11.

That is, the locking pin 61e of the locking member 61 engages with the locking recess 10e of the slider 10, thereby preventing the slider 10 from sliding, and the guide pin llb of the drive link 11 engages with the notch 63b of the locking lever 63. The movement of the drive link 11 is facilitated by the engagement.

Therefore, even if you try to push down the top plate 13 in the standby state, you will not be able to push it down.

Also, the barrier, which was closed in the retracted state, will open. When in the retracted state, the photographing lens unit 1~
19 is stored in the main body case 4, in FIG. It is located in the department. In other words, in the retracted state, there is no connection to the photographing lens unit 1 19 or the barrier 9.
1 is located at the lower position in FIG. 15, and in this position, the barrier plate 9]a is in a closed position covering the front of the photographing lens 1.9a as shown by the two-dot chain line. Then, as described above, when the lens 19 -I- rises to the photographing lens unit 1, the operating rod 9] and b of the barrier 91 are moved to the guide 1 (the groove 9).
] d and ascends in the same way. This kite groove 9
1. Since d is formed to be inclined as shown in FIG. 15, the tips of the operating rods 1 to 91b will retreat as the rods 1 to 91b move upward. For this reason, the operating rod 91b
The actuating arm 9]e connected to the earthwork rotates counterclockwise about the axis 9], f from the position shown by the dotted chain line in Fig. 5 to the position shown by the solid line. Since the shafts 9 ] and f are provided with drive gears 9 ] and f', the actuating arm 9 ] and e connected to the operating iron old C via these quick-acting gears 91g are shown in FIG. The earthwork will rotate clockwise from the position shown by the dotted chain line to the position shown by the solid line. These actuating arms 9]e are connected to the barrier brake 1 91
Since a is provided, the barrier brake l"9], a
will be opened as shown by the solid line in FIG.

As described above, the photographic lens unit 19 is raised by 1" and the barrier 91 is opened, as shown in FIG. 10, in a standby state.
Since the electric motor 3 outputs a signal indicating that it is in the standby position, the electric motor 3 is stopped even if the main switch 84 is turned on.

When the standby state is established as described above, the four lock parts of the lock part 10d of the slider 10 are locked as shown in FIG.
Attach the locking pin 61. of the locking member 61 to Oe. Since e is engaged, the slider 10 does not move backward from then on, and therefore, the rotation of the fan-shaped second gear 46 is stopped. When the fan-shaped second gear 46 stops in this way, the encoder 85
The electric motor 3 stops due to the output of the encoder 85b, but due to the stopping accuracy of the encoder 85b, the electric motor 3 rotates slightly even after the sector-shaped second gear 46 stops, and this rotation is transmitted to the sector-shaped first gear 45. There may be cases where this occurs. However, in this case, since the sector-shaped first gear 45 rotates slightly with respect to the sector-shaped second gear 46, the rotation of the sector-shaped first gear 45 is not transmitted to the -:n- sector-shaped second gear 46. . That is, the fan-shaped first gear 45 and the fan-shaped second gear 46 are shown in FIG.
As shown in FIG. 8, the rotation of the sector-shaped first gear 45 is transmitted to the sector-shaped second gear
The signal is transmitted to gear 46. When the fan-shaped first gear 45 rotates when the fan-shaped second gear 4G stops rotating, the locking lever 461) moves against the restoring force of the return spring 46e to the shaft 46c.
The recessed portion 45d is disengaged from the engagement pin 46d and the guide hole 4 is rotated slightly in the counterclockwise direction as shown in FIG.
The engagement pin/16d is located within 5c. Thereafter, by the rotation of the sector-shaped first gear 45, the engaging pin 46d
Only the fan-shaped first gear 45 rotates while the guy 1 to the hole 45c are displaced.

Note that - the above-mentioned operation occurs while the photographic lens units 1 to 19 are rising from the retracted state to the standby state. 2nd gear 4
Even if the rotation of the electric motor 3 is not stopped, the rotation of the fan-shaped first gear 45 by the electric motor 3 is allowed, so that no failure occurs in the storage operation system or the like.

The state shown in FIG. 10 is a standby state that can be used for photographing, and when a release button (not shown) is operated in this state, the shutter opens and the light is reflected by the mirror 17 and exposed onto the film 71.

When the release ends, the electric motor 3 receives the end signal.
rotates in the opposite direction. The reverse rotation of the electric motor 3 causes the pinion gear 21 to rotate in the clockwise direction in FIG.

When the rotation of this pinion gear 21 is transmitted to the sun gear 33 via the gears 22 to 31, the sun gear 33
It will rotate counterclockwise in the diagram. Furthermore, since the gear 28 is rotated counterclockwise in FIG. 10 during transmission to the sun gear 33, the upper roller 6a of the delivery roller 6 is rotated in the same direction.

When the sun gear 33 rotates in the counterclockwise direction in FIG.
Since the second stopper protrusion 82e is retracted and an appropriate frictional force acts between the sun gear 33 and the swinging arm 34, the swinging arm 34 moves as shown by the dashed line in the same figure. The planetary gear 35 rotates counterclockwise to the sending gear 5.
]. Therefore, the delivery gear 51 rotates counterclockwise in FIG. 10. When the delivery gear 5 rotates, the operating pin 51a installed therein pivots in the same direction, so when it rotates to an appropriate position, it comes into contact with the engagement tongue 550 of the claw 55, and the subsequent operation of the operating pin 51a By turning, the glow 55 is pushed to the right in FIG. 10 and moves forward.

At the rear end of the operation plate section 55b of the tallow 55, a pull-out claw section 55d facing the rear end section of the film 71 is provided.
As the claw 55 moves forward, the pull-out claw 55d engages with the rear end of the film 71, and the film 71 is pulled forward from the film pack 70. The upper roller 6a of the feed roller 6 rotates in the counterclockwise direction in FIG. When the leading end of the film 71 reaches the delivery roller 6, the film 71 is fed forward by the rotation of the delivery roller 6. At this time.

Since the lower roller 6b is pressed against the upper roller 6a by the leaf spring 7, the bot 72 at the front of the film 71 is crushed. This pot 72 contains a developer, so when it is crushed, the developer flows out onto the surface of the film 71, and when it passes through the delivery roller 6, it is spread over the surface of the film 71. 71 is developed. Further, the excess developer adheres to the two-part roller 6a and is absorbed into the liquid reservoir 73 at the rear end of the film 7I. Then, the developed film 71 is sent out to the front of the main body case 4, and the undeveloped film 71 is placed at the top of the film pack 70 to wait for the next shooting. Become.

On the other hand, when the delivery gear 51 starts rotating, the delivery gear 5
The cam recess 52a of the cam drum 52 rotates in synchronization with the
The engaging end 53a of the control lever 53 that is engaged with the first
It rides on the outer peripheral surface of the cam drum 52 from the position shown in FIG. Therefore, the control lever 53 rotates about the shaft 53b in the counterclockwise direction in FIG. 10 against the restoring force of the return spring 53d. contacts the switch piece 54a and turns on the switch 54.

After the switch 54 is turned on, the delivery gear 51 further rotates, and the operating pin 5]a of the delivery gear 51 is moved to the claw 5.
When the claw 55 is rotated to a position higher than the engagement tongue 55e, the actuating pin 5],a comes off the engagement tongue 55e, and the claw 55 becomes free. At this time, the film 71 has already been fed into the delivery roller 6 as described above, and
be drawn into. When the tallow 55 becomes free, the claw 55 retreats to the original position shown in FIG. 10 due to the restoring force of the return spring 55f and waits to feed out the next film 71.

When the delivery gear 51 rotates and the cam recess 52a of the cam 1-ram 52 engages the engagement end 53a of the control lever 53, the control lever 53 is moved as shown in FIG. 10 by the restoring force of the return spring 53d. It rotates in the direction of rotation, reaches the position shown in the figure, and turns off the switch 54. That is, when the delivery gear 51 rotates, the switch 54 is turned on and then turned off. The electric motor 3 is stopped by this changed information from ON to OFF, and thereafter the rotation of the delivery gear 51 is stopped and the camera waits for the next photographing.

Next, the photographing lens unit 1-19 in standby mode
The operation of storing the image into the main body case 4 will be explained.

In order to store the photographic lens unit 19, the switching operation lever 83 is rotated from the position shown in FIG. 10 to the position shown in FIG. 9. As a result, the input lever 83c releases the locking pins 8] and f of the operating lever 81, and the operating lever 81 moves forward to the position shown in FIG. 9 by the restoring force of the return spring 8]c. Therefore, the control member 82 whose locking protrusion 82d is engaged with the locking projection 81e of the operating lever 81 is moved forward to the position shown in FIG. 9 against the restoring force of the return spring 82c. As the control member 82 moves forward, the slots 1 to 82e of the control member 82 engage with the stopper pin 9 of the swinging arm 34 as shown in FIG. '' Rotate the planetary gear 35 from the position shown by the dotted chain line to the position shown in FIG.
It meshes with the gear 41.

Moreover, since the operating lever portion 83d is separated from the switch piece 84a by operating the switching operating lever 83, the switch 84 is switched from on to off. At this time, the encoder 85b is sending out a signal indicating that the camera is in the standby state, so this signal and the change in the switch 84 cause the electric motor 3 to rotate in the reverse direction. This reverse rotation of the electric motor 3 causes the pinion gear 21 to move to the first position.
Rotates once in the counterclockwise direction on Figure 0. When the rotation of pinion gear 21 is transmitted to sun gear 33 via gears 22 to 31, sun gear 33 rotates counterclockwise in FIG. 10. At this time, since the swing arm 34 is restrained by the stopper protrusion 82e of the control member 82, even though the sun gear 33 rotates counterclockwise in the direction M1, the planetary gear 35 and the first gear 41 are in mesh with each other. is not canceled. Therefore, the rotation of the electric motor 3 is transmitted from the planetary gear A735 to the sector-shaped first gear 45 via the drive gear 44,
The sector-shaped first gear 45 rotates in the counterclockwise direction (FIG. 10). At this time, the locking pin 6 ]e of the locking member 6J is engaged with the lock part ]Oe of the slider ]0, and the fan-shaped second
Since the gears 46 are in mesh, the sector-shaped second gear 46 is stopped regardless of the rotation of the sector-shaped first gear 45.

At this time, as described above, the recess 45d of the sector-shaped first gear 45 is disengaged from the engagement pin 46d of the sector-shaped second gear 46, and only the sector-shaped first gear 45 rotates.

Then, when the sector-shaped first gear 45 rotates to the appropriate position,
The release protrusion 45e of the fan-shaped first gear 45 is connected to the lock member 6.
1 input arm 61c, the lock member 61
is rotated clockwise about the shaft 61d from the position shown in FIG. 10 to the position shown in FIG. Due to this rotation, the engagement between the locking pin 6]e and the lock recess] and Oe is released, so that the sector-shaped second gear 46 is interlocked with the sector-shaped first gear 45, counterclockwise in FIG. 10. It will rotate in the circular direction.

Further, when the locking member 61 rotates counterclockwise in FIG. 10, its release arm 61a lifts one end of the communication lever 62 upward in FIG. A lock lever 63 is engaged with the other end of the communication lever 62, as shown in FIG. Then, it rotates about the upper shaft 63a in FIG. 1 in the opposite direction of arrow P.

This rotation of the locking lever 63 causes the notch 63b to disengage from the guide pins 11, b of the drive link 11, and the drive link 11 is released from its restraint.

When the sector-shaped second gear 46 rotates in the counterclockwise direction shown in FIG. You will move back to the left from your position.

Since the lower end of the drive link 11 has been connected to the slider IO, the lower end of the drive link 11 also moves backward. Therefore, the lower end of the driving link 11 moves away from the lower end of the driven link 12, and the top plate 1
3 is lowered, the lens frame portion 18 is also lowered, and the photographing lens units 1 to 19 are also lowered.

During the descent of the lens frame 18, the lens frame 18 comes into contact with the tip of the operating lever 81, which has been advanced to the position shown in FIG. 9 for the retracting operation. Since the top surface of the tip of the actuating lever 81 is formed into an inclined surface 81d, the actuating lever 81 is lowered by lowering the protrusion 18a of the lens frame 18.
The return spring 81. It is pushed backward against the restoring force of c. At this time, the locking protrusion 81e of the operating lever 81 slightly releases the restraint of the time control member 82, but the planetary gear 35
Since the first gear 41 and the first gear 41 are in a securely engaged state, the frictional force between the stopper pin 9 of the swing arm 34 and the stopper protrusion 82e of the control member 82 does not easily release their engagement. Then, when the protrusion 18a passes,
The operating lever 81 is positioned again in the position shown in FIG. 9 by the restoring force of the return spring 8], c.

As the top plate 13 descends, the operation panel 15 also descends, and the mirror cover 16 also descends. As the mirror cover 16 is lowered, the mirror 17 below the mirror cover 16 rotates clockwise in FIG. 10 about the shaft 17a. At this time, the mirror cover 16 is
It descends while being guided by the operating plate 15 connected to the shaft 16a in a clockwise direction (see FIG. 10) about the shaft 16a, and reaches the position shown in FIG. 9 at the lowest end.

FIG. 9 shows the retracted state, and when the slider 10 is retracted to this state, the encoder 85b outputs a signal to that effect, and the electric motor 3 is stopped by this signal. In the retracted state, the protrusion 18a of the lens frame 18 is located below the tip of the actuating lever 81, so even if an attempt is made to pull up the top plate 13 or the like from the outside, it will not be possible.

In addition, the open barrier 91 is removed from the photographing lens unit 1.
It will close as the number 9 descends. That is, when the photographic lens unit 1 to 19 is in standby state,
As shown by the two solid lines in FIG. 15, the operating rod 91b is located approximately at one end of the guide groove 91d, and the barrier plates 9]a and 91a are open. When the photographic lens unit 19 is lowered from this position, the tip of the operating rod 91b is guided by the guide grooves 9] and d, and as it descends, the shaft 91
Turn around f in the clockwise direction in FIG. 15. For this reason, the barrier plate 1-0la is pivoted from the position shown by the solid line in the figure to the position shown by the two-dot chain line and closed. In the closed state, the edges of the barrier plates 91a, 91a are brought into close contact with each other by the restoring force of the return spring 91h, and these are reliably closed.

〔Effect of the invention〕

As explained above, according to the instant camera according to the present invention, since the motor can perform the film feeding operation and the storing operation of a part of the camera, a part of the camera can be moved when not used for shooting. An instant camera that can be stored and is convenient to carry can be provided. Further, since the sending operation and the retracting operation can be performed by one motor by switching the power transmission path, there is no need to increase the weight unnecessarily. Furthermore, since the necessary motor has already been provided for film feeding, simply adding a power transmission element for the retracting operation can minimize the increase in the number of parts, making it highly convenient and inexpensive. We can provide instant cameras.
