Abstract

PURPOSE:To judge whether or not a film is fed successfully with simple constitution by providing a switch means which turns on and off corresponding to the motion of a carrier. CONSTITUTION:The switch means SW4 is operated by a carrier 22 where a planetary gear 21 is supported pivotally. While no film is wound around a spool 14, the rotation of the motor 1 is transmitted to a sprocket 25 through the driving transmission system of the sprocket 25, but when a film is taken up around the spool 14, the sprocket 25 is driven through the film. In this case, the rotating speed is more speedy than the rotating speed when the sprocket is driven through the planetary gear 21, so the planetary gear 21 is flipped away to disable the transmission through the planetary gear 21. It is therefore confirmed whether or not the film is securely wound around the spool 14 by the turn-on/turn-off operation of the switch means SW4. Consequently, it is judged whether or not the film is fed successfully with the simple constitution.

Description

[Detailed description of the invention] [Industrial application field]

In the present invention, at the time of initial loading, the film automatically fed into the spool is wound on the spool (=1
The present invention relates to a film feed detection device for a camera for checking whether or not the camera is running, and more particularly to a film feed detection device that can be applied to a camera equipped with a mechanism for automatically switching from sprocket drive to spool drive.

[Prior art] Cameras in which the film is wound electrically have been widely used in the past, and most of them are autofocus cameras, so-called ΔF-cameras, which have recently become more popular. is equipped with a film winding mechanism driven by a motor. One of the features of this type of camera is the automatic film feeding mechanism! List what you are learning. This automatic film feeding mechanism is a zero mechanism that feeds the film to the spool and automatically winds it onto the spool when loading film into the camera, that is, during the initial roll. In the latter mechanism, conventional feed detection devices include the following: 4', i.e., the filler, the presser roller and the spool. When film 1 is inserted between the film holding roller and the spool, the switch is turned off and it is determined that the initial funneling is successful.In this device, the motor The outer cylinder of the spool can be used as it is as a spool, so this method cannot be used when installing a new spool with the motor fixed. If it gets between the film and the film, it will be determined that it has wrapped around the spool, which may lead to incorrect judgments.Other conventional technologies include those that detect film advance using a member that rotates due to friction with the film; In the second half of the rotation, the sprocket is completely driven, and the rotation of the sprocket outputs a pulse signal.
There is a process for determining whether film feeding is successful or not based on the signal. These devices are complex and relatively costly. [Problem to be solved by the invention] Therefore, the problem to be solved by the present invention (J, initials [7] -1; Simple L1 to determine the success or failure of the time filler/feeding
So that it can be detected with a configuration! It's in l-rogoto. Originally, some cameras were equipped with an automatic film winding mechanism.
Some devices are equipped with a mechanism that automatically switches from the sprocket drive that drives the sprocket to the spool drive that drives the spool to wind the film at the eighth stage of feeding the film to the spool. The present invention was made by taking advantage of this mechanism, and its purpose is to use a simple structure to ensure that the film is wound onto the spool properly or not. This invention attempts to provide a film feed detection device that can confirm the above-mentioned object. was constructed as follows: 14゛, one motor drives the spool and the sprocket, and the sprocket described in - is a planetary gear mechanism. The rotational speed of the sprocket 1 when driven by the planetary gear is slower than the rotational speed of the sprocket 1 when driving the spool for winding the film. The rotation of the motor is transmitted to the planetary gear, and furthermore, a switch means is provided which is operated by a gear rear that pivots and rotates the planetary gear. (Function) -1 - According to the configuration described above, the sprocket drive by the planetary gear described in 1. is performed only under certain conditions. That is,
-1- when the film is not fully wound on the spool
The rotation of the motor is transmitted to the sprocket via the sprocket's drive transmission system, but when Film 1 is wound onto the spool, the rotation of the motor is driven via the sprocket (J Film. Since the speed is faster than the rotational speed when driven through the planetary gear, the planetary gear is thrown off and transmission through the planetary gear is no longer possible.This means that a new spool of film is required. When feeding the film, the sprocket is driven by the drive transmission system, that is, the sprocket is driven to feed the film, and the fed film is wound around the spool (
=1 After that, the spool drive, that is, the spool drive,
Then I rolled the film and went on to become a child. Therefore, it is possible to judge whether or not film feeding has been successful by means of a switch that is turned on and off in response to the movement of the gear rear. (Effect) In this way, the film is wound onto the spool, and the film is judged to have been successfully fed only when the spool is able to wind the film securely, making it incorrect to judge success or failure. There's nothing to do. Furthermore, since the conventional planetary gear mechanism is provided with a switch means (), it can be realized with a simple configuration of n11. [Embodiments] Hereinafter, embodiments of the present invention will be explained in detail based on the drawings. Figure 1 Δ is a perspective view of the entire winding/rewinding mechanism;

When a load above a certain iJ is applied to 73, the spring 4 and the friction gear 3 will slip against each other, and rotation will not be transmitted to the friction gear 3. When the reduction gear 2 rotates clockwise, the other side surface 2d of the vertical wall 2b of the reduction gear 2 pushes the other arm/Ib of the spring 4, causing the friction gear 3 to rotate clockwise. When a load of more than a certain value is applied to the gear 3, the spring 4, the gear 3, and the LJ! It will slip so much that rotation will not be transmitted to friction gear 3. In this embodiment, such a spring is used, but a compression spring may be used so that it slips when a load of a certain value or more is applied.

A suction piece +05 to be suctioned to 104 has been reserved. This magnetic magnet 104 is a combination magnet with a permanent magnet, and normally attracts an attraction piece 105. On the other hand, when a current is applied to the magnet 104, the force to attract the attracting piece 105 i'1 disappears. This magnet 104 is fixed to a vertically bent portion 120a of a plywood 120 fixed to a body (not shown). A torsion coil splinter +12 is suspended between the winding release lever 101 and the lever 103, and the bent part 101b of the winding release lever +01 and the side surface 103a of the lever +03
and are in contact with each other. Furthermore, one arm is placed on the bent portion 101c of the winding release lever 101, and the other arm is placed on the base plate 120b so that the winding release lever +01 is rotated clockwise by the coil spring I11 (-1 It should be noted that the attraction force of the magnet l-104 or the torsion coil spring 11
Since it is set to be larger than the example force in 1,
The unwinding release levers +01 and -103 cannot be rotated in the 11J direction. However, when the magnet 104 is energized, the attraction force disappears, and the winding stop release lever 101 and the levers 102, 103 are integrally rotated clockwise around the axis 27 by the torsion coil spring 111, and the winding stop is released. Lever 101
By abutting the bent portion 101a against the side surface 30d of the winding stopper lever 30, the winding stopper lever 30 can be rotated clockwise against the counterclockwise bias. The operation will be explained using the configuration as shown below. First, a normal film winding/lowering operation will be explained. In response to a release signal, a release magnet (not shown) is energized, the aperture is narrowed down, and the mirror is raised. At this time, the lever 60 moves to the right in FIG. 1A. Then, the convex portion 60a of the lever 60 is connected to the jersey winding stopper lever 4.
Press the tip 411) of I and release the jersey winding lever 41.
Rotate counterclockwise. Then, the convex portion 41a of the jersey stopper lever/II and the concave portion 40g of the one-turn cam 40 are disengaged, and the one-turn cam 40 becomes rotatable (the state shown in FIG. 8). At this time, the second switch SW2 is turned on. Thereafter, when the imager soter (not shown) runs and completes the exposure, the motor I is energized and the gear Ib of the motor 1 rotates clockwise. The reduction gear 2 rotates counterclockwise, and as shown in FIG.
4, and the spring 4 also rotates counterclockwise. The load at this time is this spring 4th friction.
Since the load is sufficiently lower than that of the sliding gear 3, the friction gear 3 also rotates counterclockwise. The first reduction gear 5 then rotates clockwise. On the other hand, since the convex portion 30a of the winding stopper lever 30 is wedged into the four parts 291) of the winding stopper gear 29, and the tip end 33b of the lever 33 is engaged with the locking plate 13, the second reduction gear 10 cannot be rotated. In other words, the three planetary gears 6 cannot rotate. Therefore, the three planetary gears 6 revolve, the gear rear plate 8, gear 7, and shaft 9 integrally rotate clockwise, and the one-rotation cam/IO rotates counterclockwise. Then, as shown in FIG. 9, the notched gear 40b of the one-rotation cam 40 meshes with the spur gear 51a of the throttle gear 51, and the throttle is geared and released, and the cam 40c moves the gear lever. 44 in the clockwise direction, and the bent portion 44b of the lever 44 is rotated so that the tip portion 601 of the lever 60 is rotated.
) to the left in Fig. 1A (right in Fig. 9) to charge the mirror and shutter, and then press the lever 60.
return to its original position. At this time, the charge winding stopper lever 41 tries to rotate clockwise due to the return of the lever 60, but as shown in FIG. Because of the different positions, the one-turn cam 40 can continue to rotate. At this time, the second switch SW2 is still in the on state. When the notch gear 40b comes off from the spur gear 51a of the aperture gear gear 5I, and the gear 41 returns to its original position and the aperture, mirror, and shutter openings are completed, the gear winding will begin at one end 40e of the concave portion 40g of the one-rotation cam 40. The stop lever 41 rotates clockwise, and the protrusion 41
a fits into the recess 40g of the one-rotation cam 40, and the second switch SW2 is turned off. Then, as shown in the timing diagram of FIG. 1I, when the second switch SW2 is turned off, a pulsed current is applied to the mucket 104, and the adsorption force between the adhesion piece +05 and the mucket 104 is increased. will disappear. Then, as shown in FIG. 6, the torsion coil spring 111 mounted on the winding release lever 101 causes the winding release lever 101 and the levers 102, 10 to be released.
3 integrally rotates clockwise, and the winding release lever 10
The side surface 30 (l) of the winding stopper lever 30 is
Press to rotate the winding stopper lever 30 clockwise to disengage the protrusion 30a from the recess 291) of the winding stopper gear 29. At this time, the first switch SW+ is turned on. Then, at the bent portion 30b of the winding stop lever 30, the lever 33
The lever 33 is rotated counterclockwise by pushing the tip 33a of the lever 33, and the engagement between the other end 33b of the lever 33 and the locking plate 13 is also released. Therefore, the second reduction gear 10 becomes rotatable. However, at this time, the one-rotation cam 40
Until 0d comes into contact with the convex portion /IIa of the charge winding stop lever 41, there is almost no load, so the planetary gear 6 continues to revolve. While the load is light, the convex portion 30a of the wind stop lever 30 and the recess 29b of the wind stop gear 29 are prevented from disengaging. At this time, the convex portion 3 of the winding lever 30
It is possible to rotate the winding stopper lever 30 with a small force in a state where almost no force due to the reaction of the planetary gear mechanism is applied between 0a and the recess 291) of the stopper gear 29. When the protrusion 41a of the jersey winding lever 41 comes into contact with the end 40d of the recess 40g of the one-rotation cam/10 (
One rotation of the cam 40 means that it has rotated once).
This time, the three planetary gears 6 begin to rotate counterclockwise, causing the second reduction gear 10 to rotate counterclockwise. And spring! 1 to rotate the spool drive gear 12 counterclockwise to rotate the spool I4 counterclockwise,
Wind the film. Furthermore, since the gear 10b of the second reduction gear lO and the large gear 20a of the reduction gear 20 are engaged, the reduction gear 20 rotates clockwise. The carrier plate 22 rotates clockwise due to the frictional force between it and the reduction gear 20, and the planetary gear 21 attempts to engage with the large gear 23a of the reduction gear 23. On the other hand, the film wound up by the spool 14 causes the sprocket 25 to rotate counterclockwise. The sprocket gear 24 and the coat plate 26 also rotate counterclockwise at the same time. The small gear 23b of the reduction gear 23 meshing with the sprocket gear 24 rotates clockwise. Here, the film is on spool 14.
When the planetary gear 21 is wrapped around the reduction gear 23
The reduction ratio is set so that the speed at which the film rotates the reduction gear 23 via the sprocket 25 is faster than the speed at which the reduction gear 23 is rotated by the film being engaged with the sprocket. Even if it tries to engage with the large gear 23a, it is immediately thrown off, and the rotation of the motor is not transmitted to the sprocket 25. In addition, in the case of initial loading, which will be detailed later,
When the film is not wound on the spool 14 (-1), the planetary gear 21 meshes with the large gear 23a of the reduction gear 23, rotates the sprocket 25 counterclockwise via the small circular gear 23b1 and the sprocket gear 24, and winds the film. By the way, as the sprocket 25 rotates counterclockwise, the two winding gears rotate clockwise. As shown in FIG. 6, when the winding gear 29 rotates a predetermined amount, the winding stops. The convex portion 29c of the gear 29 contacts and pushes the tip 102a of the lever 102, and the lever 102, the winding release lever 101, and the lever I03 are integrally moved to the axis P.
, rotate the suction piece 105 counterclockwise 7 times, and attach it to the tip of the lever 103 again.
4. Let it be absorbed. Even after the adsorption piece +05 is adsorbed to the magnet 104, the convex portion 29c keeps the lever 1
03 and the unwinding lever 101 are moved. The amount of movement is such that both levers 103, 101 continue to rotate counterclockwise while charging the torsion coil spring 112. Therefore, the attraction piece 105 can be reliably attracted to the magnet +04. roll! The L gear 29 continues to rotate, and the convex portion 29c
passes the tip 102a of the lever 102, the lever 103 and the winding release lever 101 are rotated clockwise by the twisted coil splinter +12, and the winding tension release lever 10 (bent portion 101ba) is rotated clockwise.
The side surface 103a of the lever 103 contacts and returns to its original state. Furthermore, the wind stopper gear 29 rotates, and after one rotation, the wind stop lever 3 is inserted into the recess 291) of the wind stop gear 29.
The convex portion 30a of 0 is fitted, and the rotation of the stopper gear 29 is stopped. In this way, one frame of film is fed. At this time, the first switch SW+ is turned off, and at this timing, the motor 1 is braked to complete the winding. By the counterclockwise rotation of the winding stop lever 30, the lever 33, which has been pushed clockwise, rotates clockwise, and its tip 33b is engaged with the locking plate 13. This lever 33 is provided for the following reason. When the stopper lever 29 is stopped, the brake is immediately applied to the motor I. At this time, the sprocket 25 is immediately stopped, but the spool 14 is applied by the motor I by the gear pack lason. The rotation continues due to the inertia of each gear. Then, the film tries to be unwound one more turn by the spool 14, but since the sprocket 25 is already stopped, an excessive force is applied to the film between the spool 14 and the sprocket 25. In order to avoid this, the spool 14 is stopped by the lever 33 via the locking plate 13. The winding operation is performed while the gear 1b of the motor 1 is rotating clockwise, 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. Since the rewinding gear 72 rotates counterclockwise, the friction between the gear rear plate 74 and the rewinding gear 72 causes the shaft center I.
Rotate counterclockwise 5 times. Therefore, the planetary gear 73
does not mesh with the gear 75a at the left end of the rewinding gear train 75, so that rotation is not transmitted to the rewinding fork gear 76. Also, while the spool 14 rotates counterclockwise to wind and unwind the film, the cylindrical portion of the spool 14 has two parts +4. The roller release lever 84 is attempted to be rotated clockwise by the coil splinter 85 wound around b, but the roller release lever 8a is regulated so that it cannot be rotated counterclockwise from the position shown in Figure 10. has been
The arm 85a of the coil spring 85 is the coil spring 8
5 continues to slide between the coil spring 85 and the cylindrical portion 1/Ib of the spool I4 with a light torque. Incidentally, while the film is being advanced by one frame, the third switch SW3 is repeatedly turned on and off, as shown in the timing chart of FIG. In this embodiment, the third switch SW
3 is set to turn on eight times. This is necessary to feed the film to the spool during initial loading, which will be explained next, and can also be used to know when film rewinding is complete. Next, during initial loading of the film (blank feed)
The operation will be explained. As shown in the timing chart in Figure 12, when the film is loaded and the camera back is closed, a switch (not shown) is turned on, and gear 1b of motor I is turned in the opposite direction (counterclockwise) to the winding direction. The motor 1 is energized so as to rotate 111 in the direction). This energization time is very short (about 30zs), and is only enough to move the backlash of the gear. By this operation, the load applied to the concave portion 29b of the wind stop gear 29 and the convex portion 30a of the wind stop lever 30 can be relieved when winding is completed. After that, during running when applying the brake to motor 1,
Magnet 104 is energized. Then, as described in iiQ, the side surface 30 (1) of the wind stop lever 30 is pushed by the bent portion 101a of the wind stop release lever +01, and the wind stop lever 30 rotates clockwise, and the wind stop lever 30 rotates clockwise. 29b and the convex portion 30a of the winding stop lever 30 are disengaged, and the first switch SW+ is turned on.The lever 33 rotates counterclockwise, and the end portion 33b and the locking plate 13 are rotated counterclockwise.
It also disengages. After braking the motor 1 for a certain period of time, the gear 1b of the motor 1 is then rotated clockwise. Then, the film has not yet been wound onto the spool I4 (=1), so the planetary gear 21 is connected to the large gear 23 of the reduction gear 23.
By engaging with a, the sprocket 25 is moved counterclockwise and the film is fed to the spool 14 side. As the stopper gear 29 rotates clockwise, one end of the suction piece 105 is sucked by the magnet 104.
The magnet 104 is energized again at the surface where the convex part 30a of the wind stop lever 30 fits into the concave part 29b of the wind stop gear 29, and the wind stop release lever 101 is rotated clockwise, so that the convex part 30a of the wind stop lever 30 is Concave portion 29 of winding gear 29
1] to avoid falling into it. In addition, magnet 104
The timing at which the power is applied is when the third switch SW3 is turned on for the eighth time. Convex portion 30a of winding stop lever 30
does not fit into the recess 29b of the stopper gear 29, the first switch SW1 continues to be in the on state, the motor 1 remains energized, and the spool I4
, the sprocket 25 rotates counterclockwise to start winding the film for the second frame. Then, like the acid top, when the third switch SW3 is turned on for the eighth time, the magnet 104 is energized again. Then move on to winding the third frame. Similarly, at the timing when the third switch SW3 is turned on for the eighth time, the magnet 104 is energized to start winding the fourth frame. Initially, the film was spool 14.
Since the film has not been wound down completely, the planetary gear 21 is engaged with the large gear 23a of the reduction gear 23. However, as the film is fed 2 to 3 frames, the film eventually winds up onto the spool 14, and as described above, the planetary gear 21 is engaged with the large gear 23a of the reduction gear 23. rotation becomes faster, and even if the planetary gear 21 attempts to engage with the large gear 23a of the reduction gear 23, it will be thrown away. Therefore, the fourth switch SW4 changes from on to off as the film is wound around the spool 14, and by detecting this change, it can be determined whether the initial loading was successful. If this happens, the film has not been wound onto the spool 14, so it can be determined that the film has failed, and the photographer can be warned of this fact. Then, at the above timing, the magnet [04] is not energized, the winding stop gear 29 rotates once, the protrusion 30a of the winding stop lever 30 fits into the recess 29I of the winding stop gear 29, and the first swing SWI is turned off. In this state, the brake is applied to the motor 1, and the initial load is completed. During this initial funnel, the film is wound around spool I/I. 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. 18 and 19 are examples of other differential mechanisms. In the modification shown in FIG. 18, the intermediate bevel gear 1
35 is located within the spur gear 132 and is pivotally supported by a pin 135a perpendicular to the shaft 132a thereof, and further meshes with the input helical gear 136 and the driven gear +37. Further, the spur gear 132 meshes with the pinion gear 131. Then, the driving force of the motor (not shown) is the human power axis + 3
8, it is transmitted to the two-wheel drive gear 136. When the driving force of the motor I is transmitted to the human helical gear 136, if the load acting on the output shaft 133 of the pinion gear +31 is heavier than the load on the shaft 139 of the driven force gear 137, the intermediate bevel gear 135 Rotating, driven force the gear 137
rotates. On the other hand, if the load on the output shaft 133 is lighter tJ than the load on the shaft 139, the intermediate bevel gear +35
139, and the spur gear +32 rotates. In other words, when the spur gear 132 is kept stationary (as shown by the arrow in the figure, the rotation of the input shaft +38 causes the shaft 139 to rotate in the opposite direction and at the same speed as the human power shaft 138. When the input shaft 138 rotates in the same direction at a constant speed, the shaft 139 can be rotated slowly and rapidly in both the left and right directions, and can also be made stationary. (Planetary gear mechanism; see Figure 2) and the differential mechanism explained here have component numbers 3b, 136.4, and 135.5.
, 132.8 and 137 correspond to each other, respectively. 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 series modification.This operating mechanism is used in automobiles as a differential noal gear. , is a well-known mechanism.To briefly explain this mechanism, the helical gear 14+ provided on the input shaft 138 is connected to the helical gear 1 held in the casing 149.
It meshes with 42. Furthermore, two pairs of helical gears 136, 137.1/14° 144 are provided within the casing 149. That is, as shown in the figure, two pairs of helical gears 136, 137. Each shaft-supported bevel gear 137, 136 has a casing +49
Two bevel gears 144, 144 provided on a shaft 144a which is rotatably held in the shaft 144 are in mesh with each other. Input shaft 13
When the helical gear 1/II of No. 8 rotates, the casing 149
As the helical gear 142 held in rotates, the output shaft 13
3.139 usually rotate at the same speed. However, the load acting on one output shaft 139 is
If the load is heavier than 3, the other output shaft 133 can rotate faster by one output shaft + 39 up. As is well known, when a car moves while turning,
The other output shaft 133 rotates more than the one output shaft 139 to prevent the other wheel from slipping. A detailed explanation of film rewinding will be omitted here, but in this example, as a matter of course,
Film rewinding is possible. Explaining the outline of film rewinding 4- When the filler is stretched at the last frame, the two rewinding gears stop and the first switch SWI is held in the on state. This state is measured by a built-in timer, and if the first switch SWI is not turned off even after the scheduled winding time has elapsed, the built-in control means determines that the film has finished. Then, the motor I is rotated in the direction of rewinding the film, and the rotation is transmitted to the rewinding gear 72, so that the film is not rewound into the roller. In addition, during film rewinding, the rewind stop lever 3
The convex portion 30a of 0 does not fit into the concave portion 291) of the stopper gear 29, and is controlled by a control means to be described later. Finally, let us explain a specific example of the control means used in the film winding device of this embodiment. FIG. 1) Each switch SWI, SW2.

Switch SW6 is a switch that is turned on when film film 13 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. 13, these switches SW4

Once an interrupt is started, no interrupts will be accepted until the interrupt is enabled again. BΔ(J is a power supply battery that supplies power to this circuit.

When a high level signal is output from the terminal OP, the transistor Q1 becomes conductive, current flows through the magnet Mg, and the Macnet Mg is activated. Conversely, the micro combi coater μC outputs a low level signal from the output terminal OP +. Transistor Q1 becomes non-conductive, current does not flow through magnet Mg, and magneto-Sot-Mg becomes inactive. Two ■〕N1) l-run sister Q 2 , Q

Therefore, current flows from the power supply line V to the Run Sister QJ, the motor M, and the NPN transistor Q, causing the motor M to rotate in reverse.

When a signal of the same level is output from P4.0P5, the motor M is short-circuited and the brake is applied to the motor M. Next, the operation of this microcomputer μC will be explained. First, during normal winding and We will explain the operation during auto return.When the photographer presses the release button (not shown),
Switch SW4 is turned on, and as mentioned above, the interrupt terminal IN'l"l of the micro combi coater μC falls, and the micro combi coater μC
operates according to the flowchart shown in FIG. First, as is well known, the Micro Combi Coater μC
While narrowing down the aperture, a mirror (not shown) is raised. Then, the shutter front curtain is moved to expose the film. When a predetermined time (shutter seconds) has elapsed after the first shutter curtain was run, the microcomputer μC causes the second shutter curtain to run. The above operation (
After step #I), that is, after a predetermined period of time after running the trailing curtain, the microcombicotor μC performs step #11 in order to charge the mirror, aperture, and shutter.
Proceed to. Note that a detailed explanation of step #1 is omitted because it is not directly related to the present invention. During the operation of step #I, switch SW2 is turned on. In step #11, the micro combi coater μC connects each output terminal OP2. A high-level signal is output from OP3, and a low-level signal is output from each output terminal OP, , OP5 to cause the ζ motor M to rotate forward. Micro Combi Coater μC has an aperture, a mirror,
The process waits until the turning of the gloss is completed and the switch SW2 is turned off (step #12). Microphone (l combination J-7zCIJ, input terminal IP2
The state of the switch SW2 is determined based on the signal input to the switch SW2. When a high-level signal is input to the input terminal JP2, the microphone [1 computer μC determines that the switch SW2 is turned off (switch SW4 is also turned off), and determines whether there is multiple exposure (step # 13), and it is determined whether or not film is loaded (step #14). If a low level signal is input to the input terminal TP5, the microcomputer μC determines that the switch SW5 is off and multiple exposure is being performed, proceeds to step #26, and applies a brake to the motor M. In addition, input terminal IP,
If a high level signal is input to , it is determined that the micro combi coater μC- and switch SW6 are off and no film is loaded, and the process proceeds to step #26, where the motor M is braked. Therefore, this microphone [l computer μCiJ,. If there is no film in the film, the winding will not be overdone.If the back cover is open, the switch S will be turned off.
Since W6 is turned off, no winding is performed in this case either. If there is no multiple exposure and film 11 is loaded, step #21 (winding routine) for winding the film is performed. ). First, proceed to Micro Combi Coater μC.
outputs high-level pulses at a predetermined interval from the output terminal OP to activate magnet 1-Mg (step #21).At the same time, the microcombi coater μC resets the built-in timer and then starts. Go ahead (Step #22). When the magnet 1-Mg is activated in Step #21,
As mentioned earlier, when the switch sw1 is turned on, the driving force of the motor M is transmitted to the film winding side.
Let the film wind. After starting the timer in step #22, wait until the micro-impeller has finished winding the micro-impeller or until the timer has counted a predetermined time (step #2g, 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 SW is turned off as described above, and a high level signal is input to the input terminal IF of the microcomputer μC. Microphone [l=1 When the microcoater μC detects this, it proceeds to step #26 and connects each output terminal OP.
t, outputs a high level signal from OPs and applies a brake to motor M. Thereafter, the microcomputer μC enables interrupts (step #27) and then waits until the next interrupt is issued. Normal winding is 11N
(See Figure 11)
This is the operation of C. On the other hand, when the timer measures the predetermined time, the micro combi coater μC(], each output terminal OP4゜OP5
outputs a high-level signal from the motor to apply a brake to the motor M (J).After waiting until the rotation of the motor M has completely stopped, proceed to the rewind routine (Fig. 15).It goes without saying that However, when the timer measures a predetermined time, it means that the film has reached the final frame. FIG. 15 is a flowchart showing the rewind routine. When proceeding to the rewind routine, the microcomputer μC
outputs a low level signal from each output terminal OP, OP3 to reverse the motor M (step #4I). Then, as described above, rewinding of the film is started. As mentioned earlier, when the film is stretched, the suction piece +05
If the tape is attracted to the magnet 104, rewinding becomes impossible during rewinding, and the switch SWI is turned off. Therefore, during rewinding, the microcombi controller μC determines whether or not a high-level signal is being input to the input terminal IP (step #42). If so, each output terminal 01)3.
A high-level signal is output from OF2 to brake the motor M (step #49), and a high-level pulse is output from the output terminal OP to operate the Macnet Mg (step #50). As mentioned above, it becomes possible to continue rewinding, and the microcomputer μC returns to step #41 and resumes rewinding. When the micro-J computer μC determines that rewinding is completed in step 43, it outputs a high-level signal from each output terminal OP and OP3, and brakes the motor M (step #44). 4- When the unused film is wound into the cartridge, it will be in the same state as when no film is loaded, so press the switch SW.
7 is turned off. All the while, a high level signal H7 is input to the input terminal IP7. When the microcomputer μC detects this, it determines that rewinding has been completed. In step #44, the brake is applied to the motor M and the motor M is completely stopped. Then, the micro combi coater μC outputs a high level signal from each output terminal OPt and OP5 to rotate the motor M in the forward direction ( Step #45). Thereafter, the micro combi coater μC waits until the switch SWI is turned off (step #46). When the switch SWI is turned off and a high-level signal is input to the input terminal IP +, the micro combi coater μC outputs a low-level signal from each output terminal OP4 and OP5.
After applying the brake to motor M (step #47) and allowing interrupts (step #48), the process waits until the next interrupt is applied. The following is an explanation of the operation of the microcombi, μC, which operates during auto-return. Note that the detection of the completion of rewinding in step #43 is based on the number of times the switch SW3 is turned on during rewinding, 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 rewinding 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 at an intermediate frame, the IJ 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'l'3 of the micro combi coater μC falls, as described above, and the micro combi coater μC operates according to the flowchart shown in FIG. First, Micro Combi Coater μ
C is each output terminal 01)3. Output a low level signal from OP, output a high level signal from each output terminal 01), OP5, and reverse the motor M (step #31).
). After that, the backlash of the gear moves (approximately 3
0 msec), the microcombicotor μC outputs a high level signal from the output terminal OP, and the
- Activate Mg (step #32). Then, the program proceeds to the rewind routine (FIG. 15) described above and performs rewind. The following is the operation of the microcomputer μC when the photographer causes the film to rewind midway through. Finally, the operation of the microcombi .mu.C during initial rope inking will be explained. When the film is loaded and the back cover is closed, the switch SW6 is turned on, the interrupt terminal NT2 falls, and the microcomputer μC operates according to the flowchart shown in FIG. 17, as described above. First, the microconvenience store controller μC outputs a low level signal from each output terminal OP2, 0I)3, and outputs a high level signal from each output terminal OP, OP5 to reverse the motor M. (Step #61). When a time period (approximately 30 milliseconds) long enough for the gear to move, the microcomputer μC outputs a high-level signal from each output terminal OP, 0Pff to brake the motor M (step #62). . Subsequently, the microcomputer μC outputs a high-level pulse from the output terminal OP to activate the magnet Mg (step #63). At this time, switch SWI is turned on. After that, the microcomputer μC opens each output terminal OP.
4. Output a low level signal from OP5 to rotate the motor M in the forward direction. Then, as described above, the sprocket 25 rotates and the switch SW3 is turned on and off repeatedly. The microcomputer μC counts the number of times the switch SW3 is turned on, and when the switch SW3 is turned on eight times, the microcomputer μC determines that one frame of film has been fed (step #65). Thereafter, the microcombi coater μC determines whether four frames of film have been fed (step #66). If 4 frames of film have not yet been fed (if the film is pulled), the Micro Combi Coater μC outputs a high-level pulse from the output terminal OP, activates the MacNet Mg, and prevents the film from being stopped. (Step #67).Then, the micro combi coater μC performs step #65.
Return to 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 IP, the microcomputer/IG determines that the switch SWI is turned off, and outputs a high level signal from each output terminal OP, 01). A signal is output to apply a brake to motor M (step #69). Thereafter, the micro combi coater μC enables interrupts (step #70) and waits until the next interrupt is disabled. The above is the initial loading (
This is the operation of the microcombicoater μC (see Figure 12).The microcomputer that is the control means may also be used to control the exposure of the camera as described in Section 2. Alternatively, you can use a micro combination coater dedicated to film winding and rewinding.In this case, it will turn on when the shutter trailing curtain has finished moving, and the film will become glossy.
A switch is provided that turns off when the micro combi coater is charged, and when this switch is turned on, the micro combi coater
Start the operation from step #II in the figure. 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.

"W5 is on," I corrected myself. (15) Page 44, line 10, ``First, correct the word ``space'' to ``width''. (16) Page 47, line 5 to line 6 “Step #4
First, the statement "The microcomputer μC completes rewinding at step #43" has been corrected to "Rewinding completes at step #43." (17) On page 47, line 11, "switch 5W7J" should be corrected as "switch 5W6J." (18) On page 47, line 12, "input terminal IP7" should be corrected as [input terminal IP o First, I corrected it to J. (19) Page 48, line 11, ``Switch SW3 is on during rewinding'' has been changed to ``While rewinding,
Switch SW3 is corrected. (20) On page 49, line 10, correct the phrase ``high-level signal'' to ``high-level pulse''. (2■) Page 49, line 18, ``When the back cover is closed,'' was corrected to ``When the back cover is closed,'' first. (22) Page 50, line 17, line 18 reads, "Switch SW3 repeats on and off." [Switch SW3 repeats on and off.] ] First, I corrected it. (23) Page 51, lines 14 to 15 [The switch SWI is turned off and the input terminal IP is turned off. First, correct the text "input terminal IP, to". (24) From the 20th line of page 51 to the 1st line of page 52, it says, "Then, the micro combi coater μC enables interrupts at step #70)." It is determined whether the initialization has been performed normally (step #70). As mentioned earlier, the initial rope ink is performed normally and the film is wound onto the spool 14.
4 is turned off. Therefore, when a high level signal is input to the input terminal IP, the micro combi coater μC determines that the switch SW4 is off and the initialization has been performed normally, and proceeds to step #72. move on. Conversely, when a low level signal is input to the input terminal IP, the micro combi coater μC switches the switch S.
It is determined that W4 is on and the initial loading was not performed normally = 5-, and the process proceeds to step #71, where the photographer is warned that the initial loading was not performed normally, and then the process proceeds to step #72. Proceed to. In step #72,
"Micro Combi Coater μCIJ, enable interrupts, step #72)". 2 In the drawings, Figures 13 and 17 will be corrected as shown in the attached sheet. ”−
