Abstract

PURPOSE:To obtain almost the same function that a two-motor type camera has by one driving motor by operating a charging means and a film winding means automatically by a control means in specific order. CONSTITUTION:One driving motor 1 drives the film winding means and charging means individually through a differential mechanism, the means are equipped with 1st engaging means 29 and 30 and 2nd engaging means 40 and 41, and the operation of the charging means and the operation of the film winding means are interlocked by an engagement control means 104. The charging means and film winding means do not operate at the same time and while the charging means is in operation, the 1st engaging means 29 and 30 are put in engaging operation to inhibit the film winding means from winding a film. Consequently, nearly the same function that the two-motor type camera has is obtained.

Description

[Detailed description of the invention]

[Industrial application field]

The present invention relates to an electrically driven film winding device for a camera, and more particularly, to a camera in which a single motor charges an aperture, a mirror, a shutter, etc., and also winds and rewinds the film. The present invention relates to a film winding device.

[Conventional technology]

Conventionally, there was a type that used one motor to wind the film, and a type that set and charged the quick-return springs for the diaphragm and mirror and charged the gloss in parallel with this film winding (the so-called wine group). In addition, there are cameras that perform the release stroke using a motor and wind the film by reversing the same motor.These types of cameras all use a sprocket to advance the film and a spool to wind the film. A friction mechanism is interposed between the sprocket and the spool to absorb the difference in circumferential speed, and the friction mechanism is always activated during winding.The amount of film feed by the sprocket is A film stopper was installed to determine the film speed, and this film stopper was released during the release process or during the stop and return of the mirror.Therefore, it was necessary to perform the release process in order to wind the film. 1. You have to release the film even when it is OK to use the initial release [the action of sending fill J1 like a J-de], which wastes power and takes time. This is also wasteful, as it always moves on to the film winding process even when there is no film.In recent years, there has been an increase in the number of cameras that use the spool winding method, in which the film is wound directly on the spool.The advantages of this method are , since the above-mentioned friction mechanism is unnecessary, there is no waste as mentioned above, and the film winding time can be shortened.On the other hand, in this method,
Since the amount of rotation of the spool differs depending on the amount of film wound around the spool, there is a problem in that it is difficult to simultaneously perform gloss charging and film winding with one motor. Since this method charges through the film, there is no problem if charging is done using a sprocket that rotates as a driven camera, like in a lens-shutter camera, but - like a focal plane shutter in an eye reflex camera. This method cannot be used with shutters that have a large capacity. In addition, since the soter charge is not completed when the film is stretched, there is a possibility that light may leak during rewinding, or that the shutter may be damaged by the film during the initial reset after film rewinding is completed, which is not desirable. . On the other hand, if charging is completed before film winding, it is possible to move on to the release operation before film winding is completed, making it possible to increase the frame speed, and charging even when there are multiple exposures or when there is no film. The advantage is that all you have to do is Under these circumstances, it is desirable to perform charging and film winding separately and independently, and a two-motor system in which each motor has its own dedicated motor is adopted. However, this type of camera requires two motors and each deceleration system driven by each motor, so the space to accommodate these devices and the cost of each device increases the size of the camera body and increases the cost of the camera. This will increase costs.

[Problem to be solved by the invention]

The present invention achieves almost the same functions as those of a two-motor single-speed camera using a single drive motor, and also allows the drive motor to perform film rewinding and automatic transition to rewinding. The object of the present invention is to provide a film winding device that can accomplish this.

[Means for Solving the Problems and Actions/Effects] (Structure) In order to achieve the two-legged objective, the present invention was structured as follows. That is, the film winding device of the present invention includes one drive motor, a charging means that is driven by the drive motor and charges a predetermined mechanism, and a bipedal motor that winds the film. A film winding means is provided. Furthermore, a differential mechanism is provided which is driven by a bipedal motor and separately drives the film winding means and the charging means. Further, the film winding means and the charging means are provided with means for locking each operation. A first locking means for locking, and a second locking means provided in the above-mentioned chip 1--ch means and locking the operation of the charging means. a first detection means for detecting whether or not the film winding means is locked by the film winding means; a second detection means for detecting whether the second locking means locks the charging means; and locking control means for causing the first locking means to perform a locking operation when the charging means is in operation. , when the second detecting means detects that the second locking means has locked the charging means, the locking control means stops the operation of the second locking means. and then, when the first detection means detects that the first locking means locks the film winding means, the control means stops the driving of the two-legged motor. As a specific embodiment, the differential mechanism described above can be realized by a planetary gear mechanism described below. an input gear rotatably mounted to input the driving force of the motor; a planetary gear disposed around the input gear and driven by the input gear; and a planetary gear rotatably mounted to the shaft. and (6) - a gear that pivotally supports the floating gear and drives the charging means; a carrier rotatable integrally with the shaft and the gear; and a carrier rotatably mounted on the shaft. In addition, internal teeth that mesh with the planetary gear are arranged around the planetary gear,
and a gear for driving the film winding means. Furthermore, it is preferable that the bipedal first locking means and the second locking means are configured as follows, for example. Specifically, the first locking means for locking the operation of the film winding means regulates the rotation of the gear that drives the film winding means in the film winding direction, and , ''When the operation of the two-legged locking control means is stopped, the rotation restriction is released. The second locking means for locking the operation of the bipedal charging means is specifically driven by a gear that rotates integrally with the gear rear (that is, a gear that drives the charging means). A cam member is provided (-J, the cam member is configured to lock the rotation when it rotates once, and the lock of the cam member is released during the release stroke of the camera. (Function) According to the above configuration, one drive motor individually drives the film winding means and the charging means via the differential mechanism, and each means is provided with a locking means, that is, a first and second film winding means. A first locking means and a second locking means are provided, and
The operation of the charging means and the operation of slowly winding the film are interlocked by a locking control means. Therefore,
1. The operation of the winding means and the film winding means cannot occur simultaneously. That is, when the charging means is in operation, the first locking means performs the locking operation and the winding operation of the film winding means is prevented. Therefore, the charging means and the film winding means are automatically operated in a predetermined order under the control of the control means. In other words, in the film winding device of the present invention, first, the aperture, the mirror, and the
To drive a charging means without performing each charge such as a glosser, and then to drive a film winding means to wind the film. Further, the driving of the drive motor, the operation of each of the means, and the stopping of the drive motor are automatically controlled by the control means. Note that the film can be rewound by driving a predetermined rewinding means without going through the differential mechanism. The differential mechanism described above operates as follows. The drive of the bipedal drive motor is transmitted through the input gear to the planetary gear and the gear that drives the film winding means, thereby driving the film winding means. If the seven rollers restrict the film winding means drive gear from rotating along the film winding direction, the driving force input to the drive motor will be transferred to the input gear, the planetary gear, and the gear that drives the chaso means. and the shaft are rotated together around internal teeth disposed on a gear that drives the film winding means. In other words, the drive motor is rotating, but
The film winding means, specifically the spool, which is a component of the film winding means, is brought to a stopped state. On the other hand, if the rotation restriction of the gear that drives the film winding means is released, the driving force input to the input gear acts to cause the planetary gear to rotate in a direction opposite to the rotational direction of the input gear. The film winding means driving gear is rotated by the planetary gear in the same direction as the rotational direction of the planetary gear. That is, when the first locking means is released, the input gear and the film winding means driving gear rotate in opposite directions, and the spool also rotates. Therefore, the relationship between the rotation direction of the drive motor for winding the film and the rotation direction of the input gear is
By establishing a relationship in which the film can be wound up with the spool=11-, it becomes possible to continuously wind up the film after the charging means is activated. Incidentally, when rewinding the film onto the cartridge, the drive motor is rotated in the opposite direction to that used when winding the film. Then, a predetermined rewinding means is activated to rewind the film onto the cartridge. In this case, the film is in a stretched state during film winding, and the second
Since the locking means is not released, the carrier is held unrotatable by the second locking means. In other words, the planetary gears are only allowed to rotate on their own axis without rotating. If the planet gear rotates, the film winding means driving gear also rotates in the same direction as the planet gear rotates. In other words, if the planetary gear rotates, the gear rotates in the opposite direction to that in the case of winding. Further, in order to enable the sprocket to rotate in a driven manner, the locking by the first locking means is released. Therefore, rotation in the direction opposite to the winding direction is allowed, and the spool rotates in the film rewinding direction. In this way, it is possible to not rewind the film into the cartridge. Further, since the tension state of the film can be detected by a predetermined means, if rewinding is performed when this is detected, automatic transition to rewinding becomes possible. (Effect) Therefore, since charging is completed before film winding, it is also possible to proceed to the release operation before film winding is completed. For example, set multiple exposure mode,
When the camera is set in this mode, if the control means is controlled so as not to shift to the film winding process after the charging process is completed, multiple exposure photography becomes possible. Furthermore, it is possible to increase the frame speed, and there is also the advantage that it is only necessary to charge the film even when there is no film. Also 1
Two drive motors can wind and rewind the film. In other words, film winding and rewinding, which was conventionally done with two drive motors, can now be done with a single drive motor even in focal plane shutter cameras, and it also has the functionality that dual-motor cameras have. According to the film-containing device of the present invention, functions such as
Realized. Further, the present invention contributes to reducing the cost of the camera and making the camera body more compact.

A coil spring 85 is provided. The upper arm 85a of this spring 85 is sandwiched between the bent end portions 84b and 8/Ic of the roller release lever 84, which rotates about the same axis 26 as the roller holder 81.

The arm 4a of the splinter 4 is pushed away by the side surface 2c of the vertical wall 2b, and the splinter 46 rotates counterclockwise in the S1 direction. The load at this time is sufficiently smaller than the load that causes the spring 4 and the friction gear 3 to slip, so the friction gear 3 also rotates counterclockwise. The first reduction gear 5 then rotates clockwise. On the other hand, the convex portion 30a of the wind stop lever 30 or the wind stop gear 29

is a circle that cannot rotate, and the three planetary gears 6 cannot rotate. Therefore, the three planetary gears 6 revolve, the carrier plate 8, gear 7, and shaft 9 integrally rotate clockwise, and one rotation J)\40 rotates counterclockwise. Then, as shown in FIG.
Each time the diaphragm is engaged, the aperture is charged and released, while the cam/IOc rotates the charge lever 44 clockwise to charge L//<-44.
/I4 b By pushing the tip AI<601) of the lever 6o to the left, the mirror and shutter are turned, and the lever 60 is returned to its original position. On this day 4, the charge winding stop lever 41 (J) attempts to rotate clockwise when the lever 60 returns, but as shown in FIG. Since they are at different positions due to rotation, the one-rotation cam 40 can continue to rotate.At this time, the second switch SW2 is still in the on state.The notched gear Job is connected to the spur gear of the throttle charge gear 51. 51a, and the charge lever 41
When the diaphragm, mirror, shutter, etc. are returned to their original positions and the charging of the diaphragm, mirror, shutter, etc. is completed, the charge winding +L lever 41 rotates clockwise at one end 40e of the concave portion 40g of the one-rotation cam 40, and the convex portion 41a is rotated clockwise. Four parts 4 of one-rotation cam 40

-104 disappears. Then, as shown in FIG. 6, the winding release lever 101 and the levers 102, 103 are integrally rotated clockwise by the torsion coil spring I11 suspended on the winding release lever 101, and the winding is stopped. Press the side surface 30d of the winding stop lever 30 with the bent part 101a of the release lever 101, and release the winding stop lever 30.

WI is turned on. Then, push the tip 33a of the lever 33 with the bent portion 30b of the stopper lever 30, rotate the lever 33 counterclockwise, and press the other end 331 of the lever 33.
) and the locking plate 13 are also disengaged. Therefore, the second reduction gear 10 becomes rotatable. However, at this time, the one-rotation cam 40 is at the end 7 of the four parts 40g.
Until IOd comes into contact with the protrusion 41a of the charge stopper lever 4I, there is almost no load, so the planetary gear 6 continues to revolve. The engagement with the concave portion 29b of the wind stopper gear 29 is prevented from disengaging.At this time, a force due to the reaction of the planetary gear mechanism is generated between the convex portion 30a of the wind stop lever 30 and the concave portion 29b of the wind stop gear 29. It is possible to rotate the winding stopper lever 30 with a small force when the charge winding stopper lever 41 is hardly engaged. When they touch each other (one rotation of the cam 40 has made one rotation), the three planetary gears 6 begin to rotate counterclockwise, and the second
The reduction gear 10 is rotated counterclockwise.
Rotate the spool drive gear 12 counterclockwise via the splitter 11, rotate the spool 14 counterclockwise, and wind the film. Further, since the gear 10b of the second reduction gear IO and the large gear 20a of the reduction gear 20 are meshed with each other, the 20th reduction gear rotates clockwise. The carrier plate 22 rotates clockwise due to the frictional force between the reduction gears 207, and the planetary gear 21 is rotated by the large gear 23a of the reduction gear 23.
Trying to engage. The film being unwound by spool I4 rotates sprocket 25 counterclockwise. The sprocket gear 24 and the code plate 26 also rotate counterclockwise at the same time. The small gear 23b of the reduction gear 23 that meshes with the sprocket gear 2/I rotates clockwise. Here, when the film is wound around the spool I4, the speed at which the planetary gear 21 meshes with the reduction gear 23 and rotates the reduction gear 23 is higher than the speed at which the film is wound around the sprocket 23.
Since the reduction ratio is set so that the speed at which the reduction gear 23 is rotated through the reduction gear 23 is faster, even if the planetary gear 21 tries to engage with the large gear 23a of the reduction gear 23, it is immediately blown away. The rotation of the motor is sprocket 2.
It doesn't get through to 5. In addition, when the film is not wound around the spool I4 as at the time of initial loading, the planetary gear 21
meshes with the large gear 23a of the reduction gear 23, and the small gear 23
b, sprocket 25 via sprocket gear 2/l
Rotate counterclockwise to feed the film to the spool I4 side. By the way, as the sprocket 25 rotates counterclockwise, the stopper gear 29 rotates clockwise. As shown in FIG. 6, when the winding gear 29 rotates a predetermined amount, the two protrusions 29c of the winding gear come into contact with and push the tip 102a of the lever 102, causing the lever 102 and the winding release lever +01 and The lever 103 is integrated with the shaft center 2.
75 in the counterclockwise direction, and attach the adsorption piece 105 attached to the tip of the lever 103 to the magnet 104 again.
Let it absorb into the sea urchin. Even after the attraction piece 105 is attracted to the magnet 104, the lever +0 by the convex portion 29c
3 and the amount of movement of the unwinding release lever 101 is the same as that of both levers 10.
3. The IOI is a spoon that continues to rotate counterclockwise while charging the torsion coil spring 112. Therefore, it is possible to reliably attract the attraction piece 105 to the magnet 104. When the winding gear 29 continues to rotate further and the convex portion 29c passes the tip 102a of the lever +02, the lever 103 and the winding release lever 101 are rotated clockwise by the charged torsion coil spring 112 and are turned again. , the bent portion 101b of the winding release lever 101 and the side surface 10 of the lever 103
3a comes into contact and returns to its original state. Furthermore, the wind stopper gear 29 rotates, and when the wind stop gear 29 rotates once, the wind stop lever 30 rotates counterclockwise and the recess 2 of the wind stop gear 29 rotates.
The convex portion 30a of the wind stop lever 30 fits into the wind stop lever 9b, and the rotation of the two wind stop gears is stopped. In this way,
One frame of film will be fed. At this time, the first
The switch SWI is turned off, and at this timing, the motor I is braked and the winding operation is completed by pressing +J. By the counterclockwise rotation of the winding stopper lever 30, the lever 33 biased clockwise is rotated clockwise, and the tip 33b is engaged with the locking plate 13. This lever 33 is provided for the following reason. That is, when the winding lever 29 is stopped, the motor 1 is immediately braked (:1), but at this time the sprocket 25 is immediately stopped, but the spool I4 is stopped by the motor 1 by the gear baracralan:1 etc. The rotation continues due to the inertia of each gear.Then, the film tries to wind up further on the spool 14, but since the sprocket 25 is already stopped, the spool I/I and the sprocket 25 In order to prevent excessive force from acting on the film between 1 and 1, the lever 33 is moved up to stop the spool I4 via the locking plate 13.The film 13 is fed one frame. In the meantime, as shown in the timing diagram of FIG.
3 repeats on and off. In this embodiment, the third switch SW 3 ij is set to be turned on eight times. While the gear Ib of the motor 1 is rotating clockwise, the winding operation is performed, and during this time the second small gear 5c of the first reduction gear 5 and the rewinding gear 70°71.72 are also rotating. The rewinding gear 72 (j rotates counterclockwise, so
The gear rear plate 7 is aligned with the shaft center 2 due to IT friction with the rewind gear 72.
Rotates 5 times. Therefore, the planetary gear 73 does not mesh with the gear 75a at the left end of the rewinding gear train 75, and does not transmit rotation to the rewinding fork gear 76. Further, while the spool 14 is rotating counterclockwise to wind and unwind the film, the roller release lever 84 is rotated clockwise by the coil spring 85 wound around the cylindrical portion +4b at the top of the spool 14. ;I try to sleep, but the roller release lever 8
41j It is restricted so that it cannot rotate counterclockwise from the position shown in FIG. 10, and the arm 85 of the coil spring 85
a receives a force in the direction of winding and unwinding the coil spring 85.
Then, with a light torque, the coil spring 85 and spool 14
It continues to slide between the cylindrical part +4b and the cylindrical part +4b. Next, during initial loading of the film (blank feed)
The operation will be explained. As shown in the timing chart in Fig. 12, when the film is loaded and the camera back is closed, a switch (not shown) is turned on, and gear 1b of motor 1 is turned in the direction opposite to the winding direction (counterclockwise). Motor I is energized to rotate. This energization time is very short (about 30xs), and is enough to move the gear by the amount of pack lash. By this operation, when winding is completed, the recess 29b of the wind stopper gear 29 and the wind stop lever 30
The load on the convex portion 30a can be relaxed. Thereafter, the brake is applied to the motor 1, and at the same time, the magnet 104 is energized. Then, as described above, the side surface 30 (1) of the wind stop lever 30 is pushed by the bent portion 101a of the wind stop release lever 101, and the wind stop lever 30 rotates clockwise, and the wind stop lever 30 rotates clockwise. and the convex portion 30 of the winding stopper lever 30
a is disengaged, and the first switch position SWI is turned on. Moreover, the lever 33 rotates counterclockwise, and the tip part 3
3b and the locking plate I3 are also disengaged. After braking the motor 1 for a certain period of time, the gear +1 of the motor 1 is then rotated clockwise. Then, since the film has not yet been wound onto the spool 14, the planetary gear 21 engages with the large gear 23a of the reduction gear 23, thereby moving the sprocket 25 counterclockwise and moving the film onto the spool I.
Send it to the 4th side. By rotating the two stop gears clockwise,
One end of the suction piece 105 comes to be attracted to the magnet 104, but just before the convex part 30a of the wind stop lever 30 fits into the recess 291) of the wind stop gear 29, the magnet 104 is energized again, and the wind stop is stopped. The release lever 101 is rotated in the direction of the hour hand to prevent the convex portion 30a of the wind stop lever 30 from fitting into the four parts 291) of the wind stop gear 29. The timing at which the magnet 104 is energized is when the third switch SW3 is turned on for the eighth time. Since the convex portion 30a of the wind stop lever 30 does not fit into the recess 291) of the wind stop gear 29, the first switch SWI continues to be in the on state, and the motor 1 remains energized, so that the spool is further removed. 14. The sprocket 25 rotates counterclockwise to start winding the film for the second frame. Then, as in the previous frame, when the third switch SW 3 is turned on for the eighth time, the magnet 104 is energized again. Then move on to the third frame. Similarly, the third
At the timing when the Suinoji SW3 is turned on for the 8th time, the magnet 104 is energized and winding of 4 frames '1'' is started. At this time, at the above timing, McNet 1
04 is not energized, the two winding stop gears rotate once, and the protrusion 30a of the winding stop lever 30 fits into the recess 29b of the winding stop gear 29, and the first switch SWI is turned off, causing the motor 1 to brake. The initial winding is completed. During this initial loading, the film is wound around the J spool 14. Next, we will explain the operation when the film is stretched at the final frame. The film is stretched during film winding. At this time, the winding load increases, causing the Gisoksprinter 4 and Frissoyounger 3 to slip.At this time, the spool 14
, the sprocket 25 stops, the winding stop gear 29 also stops, and the protrusion 30a of the winding stop lever 30 does not fit into the recess 29b of the winding stop gear 29, and the first switch SWI
remains on. While the first switch SW1 is on, a timer counts, and if the first switch SW1 is not turned off even after the scheduled winding time has elapsed, it is determined that the film has finished. Then, immediately apply the brake to motor 1, and this time gear 1b of motor 1
The motor 1 is energized so that it rotates counterclockwise. The timing chart is not shown in FIG. When the gear lb of the motor 1 rotates counterclockwise, the rewind gear 72 rotates in the direction of the hour hand, so the carrier plate 74 rotates clockwise due to the frictional force with the rewind gear 72, and the rewind switching planetary gear rotates. 73 and the gear 75a at the left end of the rewind gear train 75 (FIG. 1) are engaged, and the rewind fork gear 76 rotates clockwise to rewind the film into the cartridge. On the other hand, the single-rotation cam 40 attempts to rotate clockwise, but the convex portion 41a of the charge winding stopper lever 41 abuts against the end 40e of the fourth portion 40g of the single-rotation cam 40 and cannot rotate, and the planetary gear 6 rotates. . The second reduction gear IO then rotates clockwise. At this time, the lever 33 does not lock the locking plate 13 when the second reduction gear 10 rotates clockwise, so the reduction gear 20 rotates counterclockwise and the gear rear plate 2
2 rotates in the opposite direction F + i1 around the axis P1, and the reduction gear 2I and the large gear 23a of the reduction gear 23 do not mesh with each other. Also, due to the clockwise rotation of the second reduction gear 10, The spool 14 rotates clockwise via the kick spring 11 and the spool drive gear 12. Then, the arm 85a of the coil spring 85 that is wound around the cylindrical portion +4b of the spool 14 releases the roller release lever 8.
4 clockwise. Then, the torsion coil spring 8 is rotated by the bent portion 84a of the roller release lever 84.
3's arm 83a is charged. The coil spring 85 has a transmission torque sufficient to charge the torsion coil spring 83 in the tightening direction. When the spool 14 rotates by a predetermined amount, the other arm 85b of the coil spring 85 comes into contact with a stopper provided on the body (not shown). Then, the coil spring 85 becomes unwinded, so the roller release lever 84 cannot be moved clockwise two more times, and the torsion coil spring 83 remains charged. Therefore, since the roller holder 81 is no longer subjected to the biasing horn, the wound film is loosened from the spool I4 by its own strength, and the load of unwinding is reduced. In addition, if the film is held down by the roller 82, the speed difference between the spool 14 and the film will cause the film to rub and cause scratches on the film, so in order to prevent this, the urging force of the roller boulder 81 is I'm trying to eliminate this. Rewind fork gear 76
As the film is wound into the cartridge, the sprocket 25 is rotated clockwise by the film. As a result, the reduction gear 23 rotates counterclockwise, but the planetary gear 21 is rotated by the large gear 23 of the reduction gear 23.
a and (J) do not mesh, so there is no load. Also, the winding gear 29 also rotates counterclockwise.
2a, the lever +02 rotates clockwise around the axis 28 against the torsion coil spring +10. In addition, the unwinding release lever 101 and the lever +03
remains as it is (the position shown in FIG. 6). When the convex portion 29c of the winding gear 29 passes the tip 102a, the lever 102 is rotated counterclockwise again by the torsion coil spring +10, and the tip 102b comes into contact with the bent portion 101a of the winding release lever 101. Return to the original. This operation is repeated during rewinding. In addition, when the film is tension-sawed, if the suction piece +05 is adsorbed to the Makneso l-104, as the winding stopper gear 29 rotates, the convex part 30a of the winding stopper lever 30 will eventually fit into the concave part 29b of the winding stopper gear 29. is stuck and the first switch SWI is turned off. In this state, the sprocket 25 cannot rotate and therefore cannot be rewound. Therefore, as soon as the first switch SWI is turned off, apply the brake to motor I, and at the same time turn off magnet 1.
04 disengages the protrusion 30a of the winding stopper lever 30 and the recess 29b of the winding stopper gear 29 again, and then the motor I is turned on to resume rewinding. Once this operation is performed, it will not be performed again, and it will not occur even when the film is stretched, even before the suction piece +05 is suctioned by the Macneso l-104. The rotation of the sprocket 25 causes the third switch SW3 to repeatedly turn on and off. When the film is rewound by a month's worth of frames, the third switch SW3 is turned on eight times, so the amount of rewinding is determined by counting the number of times the third switch SW3 is turned on during rewinding. Calculate the number of rolled up parts by 1-
At this point, it is determined that the return is over. And motor I
After applying the brake, the gear lb of the motor 1 is energized to rotate clockwise to cause the adhesion piece 105 to be adsorbed to the magnet l-104, and the protrusion 30 of the wind stop lever 30
a is inserted into the fourth part 291) of the stopper gear 29, and the first
When the switch SWI is turned off and winding is completed, the brake is applied to the motor 1, and the rewinding operation is completed. While the gear 1b of the motor 1 is rotating clockwise, the spool I4
rotates counterclockwise, at this time the roller release lever 84 rotates counterclockwise and returns to its original state, and the torsion coil spring 83 is attached to the roller boulder 81 again.
Since the arm 83a of the roller 82 comes into contact with the spool I
Pushed to 4-11-1. If the photographer wants to rewind the film at an intermediate frame before the film reaches the end, the photographer presses a switch, and as shown in the timing chart of FIG. Rotates in the anti-"'f n-I direction. The gear pack run unit moves (approximately 3011 seconds)
) When the winding is completed, the load is loosened by rotating the winding stopper lever 30 by energizing the magnet 104.
The engagement between the convex portion 30a and the concave portion 29b of the stopper gear 29 is released. The gear 1b of the motor 1 continues to rotate counterclockwise i-1, and the film is rewound as described above. After this, the process is exactly the same as when the film is stretched and rewound. Next, the operation during multiple exposure will be explained. If it detects that it is in multiple exposure mode, it will start winding in the same way as normal winding.
A release operation is performed, and after exposure, the motor 1 is energized to perform aperture, mirror, and soyatter charging. When the convex portion 4.1a of the charge stopper lever 41 is fitted into the four parts 40g of the one-rotation cam 40 after charging is completed, the second switch SW
2 turns off. 3. At this point, normally the magnet 107I on the upper right side is energized and the film winding process begins, but during multiple exposure, the magnet 107I is not energized and the 2nd
When SW2 is turned off, the brake is applied to motor I and the process ends with IJ. Furthermore, even when it is detected that no film is loaded, in order to avoid wasteful battery consumption, it is possible to not perform the film winding process as in the case of multiple exposure. Incidentally, in this embodiment, a planetary gear mechanism is used as the differential mechanism, but it is also possible to use other differential mechanisms. The mechanisms shown in FIGS. 20 and 21 are examples of other differential mechanisms. In the modification shown in FIG. 20, the intermediate bevel gear 1
35 is located within the spur gear +32 and is pivotally supported by a pin 135a perpendicular to the shaft 132a thereof, and further meshes with the input helical gear +36 and the driven gear +37. Further, the spur gear 132 meshes with the pinion gear 131. The driving force of a motor (not shown) is then transferred to the human power shaft 13.
8 to the manual gearwheel 136. If the driving force of the motor 1 is transmitted to the input gear 136,
If the load acting on the output shaft +33 of the pinion gear +31 is equal to the load on the driven gear +37 by 206 times (J), the intermediate gear 135 rotates, and the driven gear 137 rotates. On the other hand, if the load on the output shaft 133 is lighter than the load on the shaft 139, the intermediate bevel gear 135
Kasuke138. +39 and the spur gear 132 rotates. In other words, if the spur gear 132 is kept stationary,
As indicated by the arrow in the figure, rotation of the input shaft 138 causes the support 139 to rotate in the opposite direction and at the same speed as the input shaft 138. (
However, when the spur gear 132 is rotated, the human power shaft 138
rotates in the same direction at a constant speed, the axis +39
It can be rotated slowly or rapidly to either the left or right, and can be held still. In addition, when the constituent members of the differential mechanism described above (see Figure 2 of Planetary Gear Mechanism 1) and the differential mechanism explained here correspond, the member numbers are 3b and +36, d and 135.5 and 132. .8 and 137 correspond to each other. In another modification of the differential mechanism shown in FIG.
This is an example in which two helical gears 141 and 142 are used instead of the spur gear and pinion gear in the double modification. This operating mechanism is a well-known mechanism used in automobiles as a differential gear. To briefly explain the mechanism, a bevel gear +41 mounted on a human-powered shaft 138 meshes with a bevel gear 1/12 held in a casing 149. Furthermore, the casing 1
Two pairs of bevel gears 136, 137, and 144° 144 are provided within 49. That is, as shown in the figure, the respective helical gears 137 and 136 supported by the respective output shafts 133 and 139, which are arranged to face each other, are connected to the casing 149.
It meshes with two bevel gears +4/1 and 144 provided on a shaft 144a which is rotatably held. Input shaft 1
When the 38 helical gears 141 rotate, the casing! 49
As the helical gear +42 held in rotates, the output shaft 13
3,139 normally rotate at the same speed. However, the load acting on one output shaft +39 is applied to the other output shaft 13.
3, the other output shaft 13: can be rotated faster than one output shaft 139. This is because, as is well known, when a car moves out of a turn, The other output shaft 133 is rotated more than the one output shaft 139 to prevent the other wheel from slipping.Finally, a specific example of the control means in the film winding device of this embodiment will be explained. The figure is a circuit diagram using a microcombiner μC as a control means of the present invention. The switches SWI, SW2, and SW3 in this figure correspond to the switches SWI, SW2, and SW3 described above. One end of each switch SWl, SW2, SW3 is pulled up to the electric line V through a pull-up resistor, respectively.

The switch SW6 is a switch that is turned on when film is loaded and the back cover of the camera is closed, and turned off when no film is loaded or the back cover is open. The switch SW7 is a switch that is turned on when rewinding at an intermediate frame. As is clear from FIG. 15, these switches SW4

When any of SW7 is turned on, each interrupt terminal IN'l"1.INT2.INi"3 of the corresponding microcombiner and μC falls, and in synchronization with the falling edge, the microcombiner ;1-Event μC starts an interrupt operation to be described later. still,
This Micro Combi Coater μC is an i-1 that, once an interrupt is started, will not accept any interrupts until the interrupt is re-enabled.
It is designed not to be attached. BΔ is a power supply battery that supplies mino J to this circuit. Mg is a magnet, and in FIG. Connected.Also, Magneso 1-M
A back electromotive force prevention diode D1 is connected in parallel to g. The emitter of transistor Q1 is grounded, and the base is connected to the connection point of two resistors R, , R2. The other end of resistor R8 is the output terminal OP of the microcomputer μC. The other end of the resistor R2 is grounded. Therefore, when the microcombi device μC outputs a high-level signal from the output terminal OP1, the transistor Q1 becomes conductive, current flows through the magnet Mg, and the magnet Mg is activated. Conversely, when the microphone computer μC outputs a low-level signal from the output terminal ○P1, the transistor Q becomes non-conductive, no current flows through the magnet Mg, and the magnet Mg becomes inactive. 2 PNP) Run Sister Q 2.

When the same level signal is output from OP5, motor M
is short-circuited, and motor M is energized. Next, the operation of this microcomputer μC will be explained. First, the operations during normal winding and auto return will be explained. When the photographer presses the release button (not shown),
The switch SW4 is turned on, the interrupt terminal IN'll of the microcombicoater μG falls as described above, and the microcombicoater μC operates according to the flowchart shown in FIG. First, as is well known, the microcomputer μC narrows down the aperture and raises a mirror (not shown). Then, the shutter front curtain is moved to expose the film. When a predetermined time (shutter seconds) has elapsed after the glossy front curtain is run, the microcomputer μC causes the glossy rear curtain to run. After the above operation (step #1), that is, after a predetermined period of time after running the trailing curtain, the micro combi coater ItC operates the mirror, aperture, and gloss.
Proceed to step #11 without charging. Note that a detailed explanation of step #l is omitted since it is not directly related to the present invention. During the operation of step #1, the switch SW 2 i;I is turned on. In step #11, the microcomputer 71C is
Each output terminal OP2. A high level signal is output from OP3, and each output terminal OP4. A low level signal is output from OP5 to rotate the motor M in the forward direction. And Micro Combi 3. The controller μC performs KIF3 until the aperture, mirror, and shiner are completely charged and the switch SW2 is turned off (step #12). The microcomputer μC determines the state of the switch SW2 based on the signal input to the input terminal rP2. When a high-level signal is input to the input terminal IP2, the microcombicoater μC determines that switch SW2 is turned off (switch SW4 is also turned off), and determines whether it is multiple exposure (step #I3) and whether or not a film is loaded (step #I4). When a low level signal is input to the input terminal P5, the micro combi coater μC turns off the switch SW5 and
It is determined that multiple exposure has occurred, and the process proceeds to step #26, where the motor M is braked. Further, if a high level signal is input to the input terminal IP6, the microcomputer μC determines that the switch SW6 is off and no film is inserted, and proceeds to step #26, where the motor M
Put on the brakes. Therefore, this micro combi coater μC does not allow winding unless there is a film in it. Note that switch SW6 is turned off when the back cover is open, so in this case as well, winding is not possible (one line is not lost).If there is no multiple exposure and the film is loaded,
The process advances to step #21 (winding routine) to wind the film. First, the microcomputer μC outputs high-level pulses at predetermined time intervals from the output terminal OP to activate the magnet ME (step #21).
. At the same time, the micro combi coater μC resets the built-in timer and then starts it (step #
22). When the magnet Mg is activated in step #2I, as described above, the switch SWI is turned on and the driving force of the motor M is transmitted to the film winding side, thereby winding the film. After starting the timer in step #22, the micro combi coater μC waits until winding for one frame is completed or until the timer measures a predetermined time (steps #23 and 24). Note that this predetermined time is slightly longer than the time required for winding one frame of film (for example, 3 seconds).
It is set to . When one frame of film is wound, the switch SWI is turned off as described above, and a high level signal is input to the input terminal IP of the micro combi coater μC. When the micro combi coater μC detects this, it advances to step #26 and outputs each output terminal OF4.
Outputs a high-level signal from Or"5 and applies a brake to the motor M. Then, the microcontroller and motor IIC
After enabling interrupts (step #27), waits until the next interrupt is activated (J).The above is the normal winding operation (
This is the operation of the microcomputer μC in FIG. 11). On the other hand, when the timer measures a predetermined time, the microcombicoater μC outputs a high-level signal from each output terminal OP4°O20 to brake the motor M.
After waiting until the rotation of the motor M completely stops, the program proceeds to the rewind routine (FIG. 17). It goes without saying that the fact that the timer has counted the predetermined time period means that the film has reached its last frame. FIG. 17 is a flowchart showing the rewind routine. When proceeding to the rewind routine, the microcomputer μC
is each output terminal OP2. A low level signal is output from OF3 to rotate motor M in reverse (step #41). Then, as described above, rewinding of the film is started. As mentioned earlier, when the film is stretched, the suction piece 105
If the front is attracted to the magnet 104, rewinding becomes impossible during rewinding, and the switch SWI is turned off. Therefore, during rewinding, the microconvenience store 1-ta μC
In step #42), it is determined whether a high level signal is input to the input terminal IP, and if a high level signal is input to the input terminal IP, each output terminal OP, .
A high-level signal is output from OP3 to brake the motor M (step #49), and a high-level pulse is output from the output terminal OP to activate the magnet Mg (
Step #50). This makes it possible to continue rewinding, as described above, and the microcomputer μC again steps #
Go to 41 and resume rewinding. When the micro combi coater μC determines that rewinding is completed in step #43, the micro combi coater μC outputs each output terminal OF2. O
Output a high level signal from P3 and apply the brake to motor M (step #44). When all the films are wound into the cartridge, the state is the same as when no film is loaded, so the switch SW7 is turned off. A high level signal is input to the input terminals 11'), . When the micro combi coater μC detects this, it determines that rewinding has been completed. When the brake is applied to the motor M in step #44 and the motor M has completely stopped, the microcomputer μG outputs a high-bell signal from each output terminal OP4.01) to rotate the motor M in the forward direction (step #44). #45). Thereafter, the micro combi coater μC waits until the switch SWI is turned off (step #46). switch SW
When I is turned off and a high-level signal is input to the input terminal IP, the microcombi controller μC outputs a low-level signal from each output terminal op4 and OF2, and the motor M
After applying the brakes (step #47) and allowing interrupts (step #48), the CPU waits until the next interrupt is issued. The above is the auto return (see Figure 13)
This is an explanation of the operation of the microgo 1 computer μC. Note that the detection of the completion of rewinding in step #43 is based on the number of times the rewinding switch SW3 is turned on, as described above.
In other words, the number of times the input terminal IP3 falls is counted, and the number of times the input terminal IP3 falls (even when winding the switch SW
It may be determined that the return is completed when the number of times 3 is turned on is counted. Next, when the film does not reach the end and the photographer wants to rewind it at an intermediate frame, the Micro Combi Coater μ
The operation of C will be explained. In this case, the photographer should press the switch SW.
7 is turned on, the interrupt terminal IN'T'3 of the microcomputer μC falls, as described above, and the microcomputer μC operates according to the flowchart shown in FIG. First, the microcomputer μ
C is each output terminal OP2. A low level signal is output from OP3, and each output terminal OP4. Output a high level signal from OP5 and reverse the motor M (step #3
1). Thereafter, when the gear is moved by the amount of pack lasso (approximately 30 milliseconds), the micro combi coater μC outputs a high level signal from the output terminal OP+ to activate the magnet Mg (step #32). Then, the process proceeds to the rewind routine (FIG. 17) described above, and rewind is performed. The above is the operation of the microcomputer μC when the photographer causes the film to rewind midway through. Finally, the operation of the micro combi coater μC during initial loading will be explained. When the film is inserted and the back side is stapled, switch SW6 is turned on and the interrupt terminal I N 'J' is turned on as mentioned above.
2 falls and the micro combi coater μC
It operates according to the flowchart shown in the figure. First, the microcomputer μC connects each output terminal OP2. O
A low level signal is output from P3, and each output terminal OF,
, ○ A high level signal is output from P5 to reverse the motor M. (Step #61). After a period of time (approximately 30 msec) long enough for the gear bank lash to move, the microcomputer μC outputs the output terminals OP 2 and OP.
3 outputs a high-level signal to brake the motor M (step #62).Next, the microcombicoater μC outputs a high-level pulse from the output terminal OP and brakes the motor M. Activate (Step #6
3). At this time, switch SW+ is turned on. After that, the microcomputer μC opens each output terminal OP.
4. Outputs a low level signal from OP5 and connects motor M.
Rotate forward. Then, as described above, the sprocket 25 rotates and the switch SW3 is turned on and off repeatedly. The micro combi coater μC counts the number of times the switch SW3 is turned on, and when the switch SW3 is turned on eight times, the micro combi coater μC determines that one frame of film has been fed (step #65). Thereafter, the micro combi coater μC determines whether four frames of film have been fed (step #66). Then, if 4 frames of film have not been fed yet (J), the Micro Combi Coater μC outputs a high level pulse from the output terminal OP, activates the magnet Mg, and prevents the film from being stopped. (Step #67
). Then, the micro combi coater μC steps #
Return to step 65 and continue processing. On the other hand, when four frames of film have been fed, the microcombi coater μC waits until the switch SWI is turned off (step #68). When the switch SWI is turned off and a high level signal is input to the input terminal TP, the microcombicoater μC determines that the signal to the switch S~ is turned off, and the output terminals OP4, . Output a high level signal from OP5 = 63- to brake motor M (step #69)
). Thereafter, the micro combi coater μC enables interrupts (step #70) and waits until the next interrupt is issued. The above is the operation of the micro combi coater μC during initial loading (see FIG. 12). The micro combi coater serving as the control means may also be used to control the exposure of the camera as described above, or a microcomputer dedicated to film winding and rewinding may be employed. In this case, a switch is provided that is turned on when the trailing shutter curtain has completed its travel and turned off when the shutter is charged, so that when this switch is turned on, the micro combi coater starts operating from step #II in Figure 16. Make it. It goes without saying that it is also possible to configure the control means only by the hardware configuration of an electric circuit without using a microcomputer.
