Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for rewinding and storing a film after development processing in a film cartridge.

[0002]

2. Description of the Related Art When photographing with a camera is finished, the photographic film is rewound into a cartridge so that the cartridge can be taken out of the camera. In the lab, unwind the film stored inside from this cartridge,
A leader is attached to the tip (tongue) and the developing treatment is performed by sequentially guiding it into a plurality of liquid tanks filled with a predetermined developing treatment liquid. The cartridge from which the film was unwound was discarded. Then, after development and printing for printing are completed, the film is cut into pieces of 6 or 4 frames, inserted into respective dedicated film sheets and housed, and returned to the orderer together with the above prints.

[0003]

Discarding the film cartridge and using a dedicated film sheet causes an increase in cost, and the work of storing the cut film in the dedicated film sheet is complicated, and work efficiency is never achieved. Not expensive.

In consideration of these points, it has been proposed to return the developed film to the original cartridge and then return it to the orderer in accordance with the recent miniaturization of the film shape (Japanese Patent Application Laid-Open No. Hei. No. 122925), the cartridge mounting device, the film feeding device, and the cartridge winding device are separately configured, and do not have the integrity. Further, in the case of this type of device, considering that the leader cannot be provided at the leading end of the film, and the alignment between the slit-shaped window (opening) of the cartridge where the film is taken in and out and the leading end of the film to be rewound, The structure of the winding and inserting portion is extremely complicated. Further, since both the film and the cartridge are located in the winding section, there is a problem in how to set both of them in the winding section when considering the device as an integral unit. On the other hand, since it is preferable that the film is rewound into the original cartridge, it is also required to check the corresponding relationship.

The present invention has been made in view of the above circumstances, and it is easy to operate without any special treatment on the film or the cartridge, and the correspondence between the film and the cartridge does not interfere with the mechanism of the winding section. It is an object of the present invention to provide a film winding device having an integrity that enables checking of relationships.

The disengagement restricting claw C8 is provided so as to face the opening C40. On the outer surface side of the side plate C5, color processing or the like is performed so that the circumferential direction 3/4 with respect to the rotation center can be distinguished from the remaining area. In addition, engagement holes C9 and C9 ′ having a required diameter are formed in the center of the surfaces of the side plates C5 and C6,
A radial key groove C10 is formed in a part of the engagement hole C9 in the circumferential direction. C20 is an ID notation part which is attached at a proper place on the lower side of the peripheral surface of the cartridge C and represents the unique information (hereinafter referred to as the cartridge ID information) in the form of a bar code or the like. When the ID information is a bar code, the image sensor 4 acts as a bar code reader.

On the surface of the main body C2 facing the side plate C5, four holes C11 to C14 are formed at right angles with respect to the axis of the spool C1. In FIG. 2A, the spool position is set to "4". As for the relationship between the spool position and the film F, for example, when the spool position is “1”, it means that it is not used, when it is “2”, it means that it is in use, when it is “3”, it means that it has been photographed, and when it is “4”. When it means developed or empty. In this embodiment, the spool position of the cartridge C, which has been photographed and whose film has been pulled out for the developing process, is set to “4”. The window C3 is a slit-shaped opening through which the film F goes in and out, and a lid C15 is provided at this portion.
Is provided. The lid C15 has a long plate shape corresponding to the slit-shaped opening, and has a rotation axis (not shown) on the lower end side thereof, and the window C3 can be opened and closed by rotating the rotation axis forward and backward. In the closed state, the inside is completely shielded from light. A window shaft C16 is pivotally supported on both side plates of the main body C2, and the window C3 is opened and closed by rotating the window shaft C16 from the outside.

FIG. 3 is a plan view showing the shape of the film wound by this apparatus. The film F has a standardized predetermined width and length, and the frames F1, F2 ...
Are arranged by a predetermined number of frames, and perforations FP1 and FP2 are provided corresponding to these frames F1 and F1.

At the beginning of the film F, a first notch F10 elongated in the length direction is formed at the center in the width direction and a pair of second notches F11 having a substantially circular shape on both sides thereof. Further, magnetic or optical recording portions are formed on both sides in the width direction of the film F, and photographing information and the like (indicated by FC in the figure) are recorded in the recording portion in the form of codes. I am trying to get it. In the recording portion between the leading end of the film F and the first frame, the unique information of the film F (hereinafter,
This is called film ID information. In this embodiment, the bar code BC is optically written. A notch F12 is formed in the rear end portion of the film F on one side in the width direction.

A rack gear 63 parallel to the longitudinal direction is attached to the second slide shaft 62, and a pinion gear 642 meshing with the rack gear 63 causes a rotation shaft 641 of a motor 64 for loading and withdrawing the cartridge C.
To a torque limiter 65. The torque limiter 65 prevents the torque driving force of the motor 64 from being absorbed by the torque limiter 65 and transmitted to the pinion gear 642 when a load exceeding the allowable level is generated between the motor 64 and the slide mechanism 6, so that the torque limiter 65 is not excessive. We are trying to protect the members from damage due to load. Further, a contact piece 621 protruding downward is formed at the tip of the second slide shaft 62 (lower side in FIG. 4), and the contact piece 621 abuts a stopper 102a formed at an appropriate position of the main body 1. The contact position restricts the outward pull-out position, and the stopper 102b inside the main body is brought into contact with the stopper 102b during the inward movement to set the cartridge loading position, and the pinion gear 642 causes the rack gear 63 to move. I try not to go out of range.

The motor 64 is composed of a DC motor or the like and uses the contact sensors SE1 and SE2 (see FIG. 13) such as limit switches or the like when the contact piece 621 contacts the stoppers 102a and 102b described above. And then detect
A detection signal is output at this detection timing to stop the motor 64. Therefore, the drive force of the motor 64 during the period from the contact detection to the motor stop is effectively absorbed by the torque limiter 65. By adopting such a configuration, it is not necessary to configure a complicated control circuit for positioning control, and the circuit configuration can be simplified.

The second slide shaft 62 is provided with a bottom plate 66 which slidably supports the cartridge receiving stand 5 and on which stopper pins 661 are erected.

Of the film F by the hooking claw portion 86 (see FIG. 9) described later, with its leading end portion being sandwiched between the roller 294 and the guide piece portion 272, that is, with the leading end of the film being directed slightly downward. It is easy and secure to hook the notch F10.

9A and 9B are views showing the mechanism of the film driving unit for mounting the leading end of the film in the cartridge. FIG. 9A is a side view and FIG. 9B is a perspective view showing the structure of the hooking unit. Figure 10
6A and 6B are explanatory views for explaining a mounting operation of the leading end of the film into the cartridge. FIG. 7A shows a state where the hook portion is at the home position, and FIG. 8B shows a state where the hook portion is at the film hooking position. There is.

In FIG. 9, in the film drive unit 8, a motor 80 that rotates in the forward and reverse directions is disposed on the main body 1 side with the drive shaft 801 oriented horizontally, and the drive shaft 801 is connected to the sun gear 811. An arm 82 is rotatably attached to the drive shaft 801, and a planetary gear 812 that meshes with a sun gear 811 is rotatably attached to the tip end side of the arm 82.
The stoppers 831 and 832 regulate the rotation range of the arm 82 that rotates around the drive shaft 801 by the forward and reverse rotations of the motor 80. The stoppers 831 and 832 are provided at positions where the planet gear 812 meshes with the gear 813 and a gear 88 described later at both restricting positions. A gear 814 is further meshed with the gear 813.
An eccentric cam 815 is co-rotatably attached to the shaft of. A switch SW3 is disposed so as to face the peripheral surface of the eccentric cam 815, and the switch SW3 comes into contact with the detection piece to turn on when the protruding portion 815a of the eccentric cam 815 faces. Further, one end of a crank shaft 84 is rotatably attached to an appropriate position on the side surface of the gear 814 at the eccentric position.

The hook portion 85 is a support shaft 106 that is horizontally rotatably supported between both side frames (not shown) of the main body 1, as shown in FIG.
Support portion 851 having a required length in the depth direction of the paper
And the support shaft 1 from the back side in the length direction of the claw support portion 851.
It has a long plate-shaped swing arm portion 852 that extends in a direction orthogonal to 06 and rotates together with the support shaft 106 and the claw support portion 851. A long hole 853 is formed substantially in the center of the claw support portion 851. The support shaft 106 of the main body 1 is penetrated through the long hole 853, and the claw support portion 851 is slidable only in the direction of the long hole 853 with respect to the swing arm portion 852. It is connected. In addition, as shown in a side view, the claw support portion 851 has an extension portion 85 having a predetermined length.
4, and an abutting portion 855 that is provided so as to project toward the swing arm portion 852. The elongated hole 853 is formed to be elongated in the contact portion 855 direction, and a biasing member 856 such as a compression spring is disposed inside the elongated hole 853 to support the claw support portion 851. It is biased toward the contact portion 855 side with respect to 106. The other end of the crank shaft 84 is rotatably attached to a proper place on the side surface of the swing arm 852. A contact member 107, which is also attached to the main body 1, is arranged below the support shaft 106.

A hooking claw portion 86 is fixed to the extending portion 854. As shown in FIG. 9B, the hooking claw portion 86 has an arc-shaped base plate portion 861, a pair of guide pieces 862 on both sides of the tip thereof, and an arc-shaped outer portion at the center of the tip, A claw 863 that is inclined and protrudes in the tip direction is formed. In addition, in the hooking claw portion 86, the radius of the arc of the substrate portion 861 matches the size of the support shaft 106 and the extending portion 854, and the gap between the guide pieces 862 and the claw 863 is the cutout F11 of the film F. Are dimensioned to be located. Further, the radius of the hooking claw portion 86 and the long dimension of the long hole 853 are set so as to be a locus passing through both the window C3 and the opening C40 of the cartridge as shown in FIG.

Next, the mounting operation of the film F to the cartridge C by the film driving section 8 will be described with reference to FIGS. 9 and 10. In FIG. 10A, the hooking claw portion 8
6 is located at the position where the switch SW3 is on, that is, at the home position. In this state, the film F
Is fed to a position where its tip is clamped between the roller 294 and the guide piece 272, and is slightly lowered and stopped. After that, when the motor 80 starts rotating in the counterclockwise direction, the arm 82 rotates in the same direction and the planet gear 812 is rotated.
And the gear 813 mesh with each other, and the rotational force in the clockwise direction is transmitted to the gear 814. For this reason, the hook portion 85 has the support shaft 1
The rotation starts clockwise around 06. The hooking claw portion 86 moves toward the front end side of the film F along an arc locus as shown by a two-dot chain line. Then, when the contact portion 855 rotates to a position where it contacts the contact member 107, as shown in FIG.
As shown in (b), the hook portion 85 is lifted upward against the downward biasing force of the biasing member 856. The hooking claw portion 86 is temporarily lifted (in the radial direction) so as to draw a circular arc locus of a small diameter for the contact period between the contact portion 855 and the contact member 107. At the time of this lifting, the claw 863 enters the notch F10 of the film F from below at a large inclination (entry) angle. At this time, the leading end of the film F has a guide piece 27.
2 is directed slightly downward along the upper surface shape, and the claw 863 is moved so as to be lifted upward as described above. Therefore, the angle of penetration of the claw 863 into the notch F10 becomes larger, and Enables reliable hooking.

Then, as the rotation further progresses, the contact portion 855
When the contact state between the contact member 107 and the contact member 107 is released, it returns to the initial arc locus again. The claw 863 approaches the window C3 of the cartridge C while descending obliquely downward to return to the original arc locus, and enters the inside thereof. In this way, the penetration into the window C3 is made to jump more obliquely from the upper side compared to the original arc locus, so that even if the leading end of the film F bends slightly downward, it contacts the lower edge of the window C3. It becomes possible to lead it appropriately. Subsequently, the hooking claw portion 86 advances to a predetermined angle position along the original trajectory, and the claw 86
3, that is, the film F with the opening C40 of the cartridge C
Intrude into. By such an intrusion operation, the notch F11 of the film F is engaged with the locking claw C7, and the film F is mounted on the cartridge C. At this time, the number of teeth of each gear is set so that the base end of the crank shaft 84 is at an angular position farthest from the hooking claw portion 86. Therefore, when the motor 80 further rotates, the hooking claw portion 86 rotates. Is reversed, exits through the opening C40, and retracts toward the home position. The switch SW3 stops the driving of the motor 80 by detecting the protruding portion 815a of the eccentric cam 815, and sets the hooking claw portion 86 to the home position.

In FIG. 9, when the motor 80 rotates clockwise, the arm 82 rotates in the same direction and the planet gear 812 meshes with the gear 88.
The rotational force in the clockwise direction is transmitted to. Therefore, the roller 23 connected to the gear 88 by the shaft 213 rotates clockwise in FIG. 7 to feed the film F rearward. By adopting such a configuration, one motor 80 can perform both the feeding operation of the film F and the mounting operation to the cartridge C, and the structure can be simplified accordingly. In addition, when the film F is wound up, a drive system for feeding the film is provided on the roller 23.
Therefore, there is an advantage that it is not necessary to control the speed of the roller 23 so as to synchronize with the increase change in the winding speed corresponding to the increase change in the winding diameter.

FIG. 11 is a side view showing the mechanism of the winding drive unit for winding the film F on the cartridge C. In the winding drive unit 9, a motor 90 that rotates forward and backward toward the main body 1 has a drive shaft 90.
1 is disposed horizontally, and a sun gear 911 is connected to the drive shaft 901. The arm 92 is attached to the drive shaft 901.
Is rotatably attached, and the sun gear 9 is attached to the tip side thereof.
A planetary gear 912 meshing with 11 is rotatably attached. The stoppers 931 and 932 regulate the rotation range of the arm 92 that rotates around the drive shaft 901 by the forward and reverse rotations of the motor 90. This stopper 931
Numeral 932 is provided at a position where the planet gear 912 meshes with the gear 913 and the above-mentioned gear 713 at both regulation positions.

The gear 713 is connected to a rotary plate 914 of an encoder that can rotate together. This rotating plate 9
A light-shielding piece 914a for a half circumference is provided around 14, and the light-shielding piece 914a is detected by a rotation sensor 94 composed of a photosensor or the like arranged so as to be sandwiched between a light emitting element and a light receiving element facing each other. The rising and falling edges in the circumferential direction of the light blocking piece 914a are preset at the initial angular position of the rotating shaft 712 and the position where the opening C40 of the spool C1 faces the window C3.

A pin 913a is erected at a proper position on the side surface of the eccentric position of the gear 913. The swing arm 95 has a predetermined length, the base end side is rotatably supported by the horizontal shaft 108 on the main body 1 side, and the slit 95 is formed in the longitudinal direction on the tip end side.
1 is formed. The slit 951 is slidably fitted on the pin 913a. A fan-shaped gear 96 having a horizontal shaft 108 as a fulcrum is formed at the base end of the swing arm 95, and the gear 96 is used for the window opening / closing drive unit 7.
It is meshed with the second gear 722. Switch SW4, S
W5 is arranged corresponding to the swing range of the swing arm 95,
The swing arm 95 swung by the gear 913 detects a state of being swung by the maximum angle in both directions. The maximum angle with respect to both directions is set by the diameter of the fan-shaped gear 96 so as to correspond to the open and closed states of the window C3 of the cartridge C.

When the motor 90 is rotated in the clockwise direction, the arm 92 is rotated in the same direction to mesh the planet gear 912 and the gear 713, and the gear 713 is rotated in the clockwise direction to film the spool C1. Rotate in the winding direction. On the other hand, when the motor 90 is rotated in the counterclockwise direction, the arm 92 also rotates in the same direction to mesh the planet gears 912 and 913, and the fan gear 96 reciprocates to move the window C3 of the cartridge C. The opening and closing operations of the lid C15 are performed. By adopting such a configuration, one motor 90 can perform both the opening / closing operation of the window C3 of the cartridge C and the winding operation of the film F, and the structure can be simplified accordingly.

FIG. 12 is a view for explaining the operation of the contact member 97 set corresponding to the position of the planet gear 912.
7A shows the spool lock state when the window C3 of the cartridge C is opened and closed, and FIG.

The abutment body 97 is provided so as to be able to rotate together with the support shaft 106 for supporting the hooking portion 85 shown in FIG. 9, and has a columnar shape, and a half-circumferential portion thereof extends toward the front side and has a semicylindrical shape. Of the contact surface 971 is formed. The contact body 97 has a contact surface 97 when the hook portion 85 is at the home position.
1 is located on the upper side (see FIG. (A)), and when the hooking portion 85 is driven and the hooking claw portion 86 enters the cartridge C, the contact surface 971 moves downward with the rotation of the support shaft 106. It is located (see Figure (b)). Further, as shown in FIG. 12B, the regulation position of the planet gear 912 by the arm 92 is
The shaft 912a and the contact surface 971 of the contact body 97 are set in contact with each other. Therefore, when the film of FIG.
Since the hook 12a cannot rotate, the spool C1 does not rotate even if the hooking claw portion 86 enters the cartridge C and, for example, the tip of the film comes into contact with the locking piece and applies a rotational force to the spool C1, the spool 12 does not rotate. Held in position.

FIG. 13 is a block diagram of the film winding device. Reference numeral 120 denotes a control unit that totally controls the overall operation of the apparatus, and for example, a microcomputer is adopted. The power button 110 is provided at an appropriate position on the main body of the apparatus and supplies power to the apparatus to activate it. The set button 31 is used to instruct the image sensor 4 to read the ID information of the cartridge C. The forced loading instruction button 32 is a button for forcibly introducing the cartridge C to the loading position and instructing the winding of the film F when the read cartridge ID information does not match the film ID information. Is.

The perforation sensor 24 detects the winding amount of the film F by sequentially detecting the perforations FP1 and FP2 of the film F.
The film presence / absence sensor 26 detects the leading end of the film F being fed, feeds the film F by a predetermined amount and stops it, and accurately positions the leading end at the position of the lower inclined surface of the guide piece portion 272. Also, this film presence sensor 26
Is also used to determine an abnormal feeding when the leading edge of the film is not detected even after a predetermined time has elapsed. Display unit 30
Is formed of, for example, an LCD (liquid crystal display element) having a two-stage display column, and displays the read ID information of each of the cartridge C and the film F in two stages. Further, it is also possible to compare the difference between the two pieces of ID information and, if they do not match, display a message prompting an instruction for cartridge replacement or forced loading.

Next, the overall operation of this apparatus will be described. When the power button 110 is turned on, the apparatus is activated, the initial setting operation is performed, and the operable state is set. The initial setting state means initialization of the control unit 120, setting of the hooking unit 85 to the home position, setting of the gear 722 to the window closing position, and setting of the gear 713 to the angular position corresponding to the spool position “4”. Etc.

In this state, the lid 1a is closed and the film F
Is inserted or the cartridge C is mounted. Here, it is assumed that the film F is mounted first. When the leading end side of the developed film F is inserted from the insertion opening 20 by the operator to the position where the leading end of the film F exceeds the position of the perforation sensor 24 and is held by at least the roller 23 and the driven roller 28,
The insertion of the film F is detected by the perforation sensor 24, and the motor 8 is detected according to the detection result.
0 starts rotating in the clockwise direction to rotate the roller 23 via the gear 88. As a result, the film F is automatically taken into the main body.

When the leading edge of the film F is detected by the film presence / absence sensor 26, the drive of the motor 80 is stopped for a predetermined time or by supplying a predetermined number of drive pulses to the motor 80. At this stop position, as described above, the tip of the film F has the guide piece 272 and the roller 294.
It is a position that is held by. The film ID reading sensor 25 reads the ID information recorded in the recording unit of the film from the start of feeding the film F to the stop, and displays the result on the display unit 30, for example, in the first stage. Here, when the loading of the cartridge C is completed, the hooking portion 85 is subsequently driven to engage the notch F11 at the leading end of the film F with the opening C40 of the spool C1 of the cartridge C. On the other hand, when the loading of the cartridge C is not completed, the system stands by in this state. This is because it is not possible to confirm whether the window C3 of the cartridge C is open or closed and whether the spool C1 is set at a predetermined spool position.

Next, the loading of the cartridge C will be described. When the power button 110 is turned on, the slide mechanism 6 operates and the cartridge receiving stand 5 is pulled out to the external mounting position. Therefore, the operator mounts the cartridge C on the cartridge receiving stand 5 in a predetermined direction. When the cartridge C is installed in a predetermined direction, the ID
The notation C20 faces the image sensor 4 below.

When the set button 31 is operated in this state, the image sensor 4 operates and the ID of the cartridge C is changed.
The information is read and displayed on the second stage of the display unit 30, for example. Both ID information are once taken into the cartridge ID memory 121 and the film ID memory 122 in the control unit 120, and the comparing unit 123 compares the difference between the two. Both ID
When the information matches, the driving of the motor 64 is started and the cartridge C is started to move toward the loading position inside the main body. On the other hand, if the two pieces of ID information do not match, a message to that effect is displayed on the display unit 30 and the drive start of the motor 64 is prohibited. Here, when the operator replaces the cartridge C and operates the set button 31 again, the same operation as described above is performed. Alternatively, when the forced loading instruction button 32 is operated, the motor 64 is driven to start moving the currently loaded cartridge C toward the loading position inside the main body.

It is also possible to manually move the slide mechanism 6, in which case both IDs are
If the information does not match, an alarm is issued, or a restricting member that restricts the slide of the cartridge receiving tray 5 into the main body is set to the interference position, and when the set button 32 is operated in this state. It is also possible to retract this restriction member from the interference position.

Subsequently, the cartridge receiving stand 5 is moved to the motor 64.
And the slide mechanism 6 moves to the loading position, and when approaching the loading position, the loading detection pin 73 causes the switch S.
It is determined whether W2 is turned on. Switch SW2
If is left off, it is considered that the cartridge C is not mounted on the cartridge receiving stand 5, and the display unit 30 displays that fact. If the switch SW2 is turned on, it is determined that the cartridge C is properly mounted on the cartridge receiving stand 5, and the on / off state of the switch SW1 is determined.
In this state, the pivot pins 601 and 602 are engaged with the engagement hole C9 ′ and the window shaft C16.

Further, since the cartridge C is normally in a state in which the window is closed at the time of being mounted in the apparatus,
The rotating shaft 721 fits on the spool. Furthermore, spool C
Since 1 should also be set to the spool position "4", normally, the rotating shaft 712 fits in the engaging hole C9 of the spool C1, and the switch SW1 remains off. On the other hand, if the spool position is other than "4", the switch SW1 is turned on. When the switch SW1 is turned on, the control unit 120 rotates the motor 90 in the clockwise direction (FIG. 11), and detects when the switch SW1 is turned off when the rotation shaft 712 is rotated. The position of the spool is detected based on the rotation amount at this time. Since the rotation shaft 712 is rotated while the window C3 of the spool C1 is closed, that is, the rotation of the spool C1 is restricted, the rotation shaft 712 is rotated with the engagement hole C9 and the rotation shaft 712 pressed. Even if the spool C1 is rotated, the spool C1 does not run around, so that the spool position can be accurately detected.

If the spool position is "1", "2" or "3", an unused cartridge, a cartridge in use, or a cartridge before development (in these cases, a film is loaded inside) Therefore, the display unit 3 determines that the cartridge is inappropriate.
A message to that effect is displayed at 0. When the position of the spool is "4", a rotation operation for setting the leading end of the film F in a direction (see FIG. 10) in which it can be engaged with the key groove C10 of the spool C1 is instructed. The control unit 120 first rotates the motor 90 in the counterclockwise direction to turn on the switch S.
The spool C1 is rotated by rotating the switch W5 from the ON state (window closing position) to the switch SW5 turning on (window opening position).
After allowing the rotation of the motor, the motor 90 is rotated in the clockwise direction in the opposite direction to the spool until the rotation sensor 94 of the encoder changes the level from ON to OFF (or OFF to ON). C1 is set so that the film F can be engaged with the opening C40.

After that, the motor 80 is started to rotate in the counterclockwise direction to rotate the hook portion 85 along the arc locus. As a result, the notch F11 at the leading end of the film F is engaged with the locking claw C7 in the opening C40 of the spool C1, and in this state, only the hooking portion 85 returns to the home position. At this time, even if the hooking portion 85 and the film F come into contact with the spool, the abutment body 97 that is integrally rotatably fixed to the support shaft 106 does not come into contact with the spool so that the spool does not unnecessarily rotate and no angular deviation occurs. The surface 971 is the shaft 9 of the planet gear 912.
The rotation of the spool C1 is regulated by making contact with 12a.

Then, when the hook portion 85 returns to the home position, that is, when the leading end of the film is engaged with the opening C40 of the spool C1 of the cartridge C, the motor 90 is rotated in the clockwise direction to wind the film F. To start. It should be noted that, by keeping the gear 88 released from the planetary gear 812 during film winding, even if the winding speed increases (changes) due to an increase in diameter due to film winding, it is not affected. I have to.

The winding amount of the film F may be detected by the perforation sensor 24, or may be stopped a predetermined time after the trailing edge of the film is detected by the film presence / absence sensor 26. Further, since the spool position needs to be set to "4" in the winding completion state, the rotation sensor 94 of the encoder stops the driving of the motor 80 at the timing coincident with the home position. The film presence / absence sensor 26 detects, for example, the motor 8 after detecting the trailing edge of the film.
When the cutout F12 is engaged with the locking member in the immediate vicinity of the window C3 of the cartridge K with a weak impact force by switching the rotational speed of 0 to a low speed, and when the film F is unrolled from the cartridge K later, It is designed to deliver more reliably.

Further, in the present invention, the display unit 3 displays various states.
Although it is displayed at 0, it may be notified by voice or alarm instead of the display or together with the display.

Further, in this embodiment, the film insertion port 20
Is provided on the left side surface of the main body 1, and the cut ridge receiving base 5 is provided at the front right corner of the main body 1. The guide from the outside of the cartridge and the feeding of the film are properly performed with respect to the internal cartridge loading position. As long as it is performed, the film and the cartridge may be taken in from the required side surface portions, for example, the opposite side surfaces.

FIG. 14 is a side view of the automatic film developing apparatus to which the present invention is applied. The automatic film developing device is a film F that has been photographed and wound in a cartridge C.
A film pull-out section 11 for drawing the film F, a film processing section 12 for developing the film F having been photographed, a film winding apparatus section 13 for winding the developed film F into the cartridge C, and a film winding apparatus section 13 from the film drawing section 11. The cartridge transport unit 14 delivers the cartridge C to the cartridge. The film winding device according to the present invention is applied as the film winding device unit 13.

This automatic film developing apparatus is equipped with a transport motor 1.
4a is driven to move the cartridge transport unit 14 to the slide shaft 1
The predetermined cartridge C set in the rack 14c is held by being slid along 4b and set in the film pull-out portion 11. Each drive shaft 1 is attached to the spool C1 and the window C3 of the cartridge C set in the film drawing portion 11.
After inserting 1a and 11b and opening the window C3, the spool C1 is rotated in the opposite direction to feed the head of the film F from the inside. The film F sent out next has a roller pair 1
After being switched back to the film storage section 11e by 1c and 11d, the film storage section 11e is reversed to switch the front and back to guide the film F to the development processing section 12.

The development processing section 12 is composed of a developing solution tank, a bleaching solution tank, a fixing solution tank, and a stabilizing solution tank. The film F is developed through these tanks in order, and then the heater 1 is used.
It is dried at 1f. The dried film F is guided to the film winding device unit 13 via the loop forming unit 11g and the roller pair 11h. The loop forming unit 11g drives the film feed roller pair 11h at the same timing because the film winding device 13 does not wind the film at a constant speed but gradually increases the speed depending on the winding diameter as described above. Since it cannot be carried out, it has to be released during winding, and therefore, when feeding by the roller pair in the heater 11f, a loop with an extra length is formed in advance. Then, the leading end of the film F is inserted into the insertion opening 2 of the film winding device unit 13 by the roller pair 11h.
0 (see FIG. 1) and the roller 23 shown in FIG.
The sheet is fed to a position where it is held by the roller 28. on the other hand,
The cartridge C to which the film F has been fed is conveyed by the cartridge conveying section 14 to a position above the film winding device section 13 and is mounted on the cartridge receiving stand 5 here.

In the present embodiment, the film winding device section 13 is provided with the insertion opening 20 facing downward, but such a configuration can also be adopted. In this case, the structure of the cartridge receiving stand 5 is the cartridge C.
With the window C3 facing downwards,
It is configured to be attached to. Further, the film winding device can be applied in the posture shown in FIG. In this case, the film F fed from the roller pair 11h is oriented horizontally, and the cartridge transport unit 14 rotates the cartridge C clockwise by 90 ° from the holding angle posture, and then mounts it on the cartridge receiving stand 5 from above. You can do this.

After the cartridge C is mounted on the cartridge receiving stand 5, the ID information of the cartridge may be automatically read without operating the set button 31 and the coincidence with the ID information on the film side may be determined, or When applied to this automatic film developing apparatus, it is not necessary to perform the determination processing because they are in a coincidence relationship. Subsequent film winding is performed in the same manner as in the film winding device shown in FIG.

[0078]

According to the invention described in claim 1, a film feeding means for feeding the film inserted into the film insertion opening formed in the main body of the apparatus toward the winding section of the apparatus, and the main body of the apparatus. Since the cartridge cradle is provided on the other side surface of the cartridge and the cartridge cradle is removably mounted, and the moving means that moves the cartridge cradle toward the winding unit, Workability is good because the position where the cartridge is taken into the main body is different, and since the cartridge is mounted on the exposed portion and moved inside, it is easy to set, remove, or replace.
