Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film processing apparatus and method for locking the leading end of a photographic film on a spool.

[0002]

2. Description of the Related Art A 35 mm photographic film with a cartridge is a spool around which a photographic film of a specified length is wound,
It is composed of a patrone body which holds this rotatably. When manufacturing such a photo film with a cartridge, insert the tip of the photo film into the slit of the spool, and lock the film locking hole with the nail in the slit, I am trying to attach it to the spool. Therefore, in the photographic film manufacturing apparatus, a fixed length feed sprocket, a trimmer, a film guide, and an insert roller are arranged in order, and the continuous photo film is cut by the trimmer and at the same time the front end and the rear end are cut. The end of the photo film is processed and sent into the slit of the spool.

For example, in Japanese Unexamined Patent Publication No. 2-222946, a standard length feed sprocket is rotated to start a standard length feed of a photographic film, and after the leading edge of the film has passed through an insert roller, the air type film conveyance path is opened. In this state, when the leading end of the film approaches the spool, the insert roller is decelerated to the insert speed so that the locking hole of the film front end is securely locked to the locking claw of the spool.

[0004]

In order to shorten the cycle time in the apparatus described in this publication, the film transport speed is increased, and then the film transport path is opened after the leading edge of the film has passed through the insert roller. The traveling distance of the film becomes long during the traveling period up to and the subsequent period of deceleration to the insert speed. Therefore, it is necessary to increase the distance between the insert roller and the spool. As a result, the insert guide becomes long, and as a result, the film sags between the insert roller and the spool, which makes the insert operation unstable and may cause the film to bend.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a photographic film processing apparatus and method capable of reliably engaging the leading end of the film with the spool even when the film conveying speed is increased.

[0006]

In order to achieve the above object, the photographic film processing apparatus according to claim 1 is provided on the film entrance side of a trimmer, and a continuous photographic film having a length corresponding to a prescribed number of photographed images is provided. Is provided on the film exit side of the trimmer, the trailing end feeding means for feeding the trailing end of the photo film cut by the trimmer to the outside of the trimmer, and the trailing end of the trailing end feeding means on the downstream side of the film feeding. A first film guide means provided for feeding the photographic film to the spool; the insert feeding means is arranged near both ends of the film guide in the film feeding direction of the film guide for guiding both edges of the photographic film;
And a second insert roller. Therefore, even when the fixed-length feeding of the photo film is performed at high speed to shorten the cycle time, the photo film is fed by the two insert rollers, so that the tip of the photo film is reliably fed to the spool and the photo film is fed. The insert can be done reliably.

In the photographic film processing apparatus according to the second aspect of the present invention, a guide position for guiding both edges of the photographic film and a loop space for storing the photographic film in a loop are provided between the trailing edge feeding means and the insert feeding means. A film guide means that is displaced between the retracted position for opening and the retracted position is provided, and first and second sensors that detect the leading end of the photographic film are sequentially arranged in the insert feeding means.
An insert sensor for detecting the insert of the photo film is arranged on the spool, the photo film is cut by a trimmer, and then the fixed length feeding means, the trailing end feeding means and the insert feeding means are rotated to start feeding the photo film. After detecting the leading edge of the photographic film with one sensor, the film guide means is set from the guide position to the retracted position, and the second
After the sensor detects the leading edge of the photo film, the film feed speed of the insert feed means is reduced to the insert speed, and the feed of the insert feed means is stopped after the insert sensor detects the photo film insert. After feeding the continuous photographic film for a certain length, the feeding of the fixed length feeding means and the trailing edge feeding means is stopped,
After that, the trimmer is operated to cut the continuous photographic film, and then the trailing edge of the photographic film is fed by the trailing edge feeding means. According to this, in addition to the standard length feeding of the photo film can be performed quickly, the leading end of the photo film can be surely inserted into the spool.

In the photographic film processing apparatus according to the third aspect of the present invention, the trailing edge feeding means is composed of a feeding roller pair consisting of a driving roller and a pressing roller, and after the insert feeding means is decelerated, one of these rollers is moved to the other side. The roller is displaced about the shaft center of the roller to change the feeding direction to orient the deflection of the photographic film loop. This prevents contact between the films due to bending of the photographic film.

According to a fourth aspect of the present invention, there is provided a photographic film processing method, wherein the insert means comprises a film guide and first and second insert rollers which are sequentially provided at both ends of the film guide in the film feeding direction. The film guide length is set longer as the film feeding speed is increased by the fixed length feeding means, and the photographic film is cut by the trimmer, and then the fixed length feeding means, the trailing end feeding means, and the insert feeding means are rotated. Then, the feeding of the photographic film is started, and after the leading edge of the photographic film has passed the first insert roller of the insert means, the film guide means is set from the guide position to the retracted position, and the film guide means is moved to the retracted position. After being set, the first insert roller and the second insert roller are decelerated to insert. At the speed, after the insertion of the photo film on the spool is detected, the feeding of the insert feeding means is stopped, and the continuous photo film is fed by the length corresponding to the specified number of shots, and then the fixed length feeding means and the trailing edge feeding means The feeding is stopped, then the trimmer is operated to cut the continuous photographic film, and then the trailing edge of the photographic film is fed by the trailing edge feeding means. As a result, the photographic film can be fed at a constant speed at a high speed, and the cycle time can be shortened.

Further, in the photographic film processing method according to the fifth aspect, the length from the center of the trimmer to the center of the spool is set to be slightly shorter than the length corresponding to the minimum specified number of shots. . As a result, even if the cutting length size is changed, the basic sequence does not change and only the fixed length feed amount is changed. Therefore, control of the photo film processing apparatus that processes a plurality of cutting length sizes is performed. Will be easier.

And an insert guide 76. The standard length feed sprocket 70 is arranged on the film entrance side of the trimmer 16, and also serves as the dot printer 26 as described above. The film rear end feed roller pair 71 is arranged on the film exit side of the trimmer 16.

The fixed length feed sprocket 70 is rotated by a fixed length feed motor 80. The fixed length feed motor 80 is rotationally controlled by the sub control unit 39 via the driver 81. The sub control unit 39 determines the corresponding film feed amount based on the film size information from the control unit 14. The trailing end feed roller pair 71 is rotated by the trailing end feed motor 82. Further, the first and second insert roller pairs 72 and 73 are rotationally controlled by the insert motor 84 via the timing belt 83 so as to have the same feed speed. The rear end feed motor 82 and the insert motor 84 are also drivers 85, 86.
The rotation is controlled by the sub control unit 39 via the.

The first film guide 74 is arranged between the rear end portion feed roller pair 71 and the first insert roller pair 72. The film guide 74 is composed of an upper guide plate 88 and a lower movable guide plate 89. As shown in FIG. 5, the lower movable guide plate 89 is composed of two flaps 89a and 89b, and is swingably attached about a shaft 89c extending in the film feeding direction. These flaps 89a, 89b
Is displaced by the guide plate opening / closing mechanism 90 between the horizontal guide position shown in FIG. 5 and the retracted position shown in FIG. These two flaps 89a,
89b functions as an entrance door of the film loop chamber 29. As shown in FIG. 6, when the flaps 89a and 89b are in the retracted position, the film loop chamber 29 is opened, and the continuous photo film 10 is stored in a loop shape inside the film loop chamber 29.

The second film guide 75 includes the first and second film guides 75.
It is arranged between the insert roller pair 72, 73,
The film guide 75 is composed of an upper guide plate 92 and a lower movable guide plate 93. As shown in FIGS. 7 and 8, the lower movable guide plate 93 is a guide plate main body 93.

As shown in FIG. 1, the insert guide 76
Is arranged so as to guide the central portion in the width direction of the continuous photo film 10 on the front end side of the second film guide 75. As shown in FIG. 9, this insert guide 76
Is an upper guide block 95 and a lower guide block 96.
It is composed of Both of these guide blocks 95,
The guide surfaces 95a, 96a of the upper and lower guide blocks 96 have a concave shape, and the guide surface 95a of the upper guide block 95 has a concave shape. Is formed in a ridge. Also, the second guide block of the lower guide block 96
The guide surface on the side of the film guide 75 is an inclined surface 96b, and the inclined surface 96b smoothly guides the leading end portion 10b of the continuous photo film 10 sent from the second film guide 75 to a convex guide surface 96a. You will be guided to. When the tip portion 10b of the continuous photo film 10 passes between the guide surfaces 95a and 96a of the insert guide 76, the tip portion 10b is inserted into the slit of the spool in a gutter-shaped curved state. The second film guide 75, the insert guide 76, and the pair of insert rollers 72, 73 constitute an insert feeding means. In this embodiment, the insert guide 7
Although 6 is attached to the tip of the second film guide, it may be arranged separately. In this case, the lower guide block 96 is provided with a guide plate opening / closing mechanism 94 so that it can be displaced between the guide plate and the retracted position like the lower movable guide plate 93 of the second film guide 75. .

As shown in FIG. 1, a first sensor 97 and a second sensor 98 are arranged on the second film guide 75. These sensors 97, 98 are composed of infrared projectors 97a, 98a and infrared receivers 97b, 98b. The first sensor 97 and the second sensor 98 sub-control the output signal at a low level "L" when the continuous photo film 10 is present, and at a high level "H" when the continuous photo film 10 is not present. Send to section 39. In the sub control unit 39, the output signals of the sensors 97 and 98 are “H”.
From "L" to "L", it is determined that the leading edge of the continuous photo film 10 has passed the positions of the sensors 97 and 98.

The sub-control unit 39 uses the third station ST.
When the spool 31 is set on the sheet No. 3 and the completion of the setting is detected, the fixed length feed motor 80 and the rear end feed motor 8
2. The insert motor 84 is rotated with a draw ratio so that the film feeding speed becomes higher as it goes downstream. The draw ratio is, for example, 0.1% to 5%, so that the continuous photographic film 10 between the rollers does not sag. The film feeding is started during the index feeding from the second station ST2 to the third station ST3,
The cycle time may be shortened.

Next, the sub control unit 39 causes the first sensor 97
When it is detected that the leading edge of the continuous photo film 10 has passed based on the output signal obtained from the lower movable guide plate 8
9 is displaced from the guide position shown in FIG. 5 to the retracted position shown in FIG.

When the second sensor 98 detects the leading edge of the continuous photo film 10, the sub control unit 39 decelerates the insert motor 84 to feed the film 10 at the insert speed. As shown in FIG. 9, when the leading end portion 10b of the continuous photo film 10 passes through the insert guide 76, the guide faces 95a and 96a of the guide blocks 95 and 96 make the continuous photo film 10 into a gutter shape. As shown in (3), it is inserted into the slit 31c of the spool 31. As a result, the leading end portion 10b of the film is securely inserted into the slit 31c without being bent, and the locking hole 10
a is locked by the claw 31d.

When the film tip 10b projects from the slit of the spool 31, the insert detector 99 detects the film tip 10b. Insert detector 9
Reference numeral 9 includes a detection lever 99a and an infrared light emitter / receiver 99b. The infrared light emitter / receiver 99b outputs an insert completion signal by detecting the displacement of the detection lever 99a due to the completion of insertion. This insert detector 9
The film leading edge detection signal from 9 is sent to the sub control unit 39. The sub control unit 39 determines the completion of the insertion based on the film leading edge detection signal. As a result, the rotation of the insert motor 84 is stopped and the lower movable guide plate 93 of the second film guide 75 is set from the guide position to the retracted position. By setting to this retracted position,
The film loop chamber 29 below the second film guide 75
(See FIG. 2) is opened.

Even when the insert motor 84 stops rotating, the regular-length feed roller 70 and the trailing-end feed roller pair 71 continue to rotate so as to feed the continuous photo film 10 by the specified length. The continuous photo film 10 is stored in the form of a loop, and the loop is gradually enlarged. Then, when it is determined from the signal of the rotary encoder 100 that the fixed length feed roller 70 has fed the film of the specified length, the rotations of the fixed length feed motor 80 and the rear end portion feed motor 82 are stopped. After that, the trimmer 16 is operated to separate the continuous photo film 10 into the photo film pieces 27. After the trimmer 16 is operated, the film rear end feed motor 82 is rotated for a predetermined time, and the photographic film piece 2 is moved by the rear end feed roller pair 71.
The rear end portion 27a of the sheet 7 is discharged from the trimmer 16 into the film loop chamber 29.

As shown in FIG. 10, the rear end portion feed roller pair 71 is composed of a feed roller 105 rotated by a rear end portion feed motor 82 and a pressing roller 106. Then, the pressing roller 106 moves the swing arm 10
7 is rotatably mounted. Swing arm 107
Is mounted coaxially with the feed roller 105 so as to be rotatable within a range of 45 degrees. A solenoid 108 is linked to the swing arm 107. The solenoid 108 is controlled by the sub-control unit 39, and is turned on at the initial stage of formation of the free loop of the continuous photo film 10 after the insert motor 84 starts decelerating, and the swing arm 107 is rotated counterclockwise by 45 degrees. Let As a result, the loop formation is directed. Since the loop formation is directed in this manner, the loop is not formed upward and the photosensitive emulsion surface of the continuous photographic film 10 does not come into contact with the apparatus. Furthermore, after the loop is formed upward, fluctuations in the transport load when the loop forming direction changes from top to bottom are eliminated. The swinging angle of the swinging arm 107 is not limited to 45 degrees, and may be appropriately changed according to the shape of the film loop, the size of the loop chamber 29, and the like. FIG. 11 is a flowchart for explaining the processing procedure in this embodiment.

Next, the operation of the manufacturing system for the photographic film cartridge 28 will be described. First, the film size is input from the setting device 25. The control unit 14 operates the switching device 38 according to the film size based on the film size information, and selects one of the cartridge feeders 60. Further, the control unit 14 controls the information to be side-printed according to the film size and the continuous photo film 10.
Determine the length to cut.

When the control section 14 is instructed to start the system, the processing of the continuous photo film 10 is started. Continuous photo film 1 drawn from photo film roll 11
At 0, perforations are formed on both sides by a punching machine 13 at a constant pitch. Side belt printer 15
The dot printer 26 prints a frame number, a DX code, etc. according to the side belt and the film size on both sides of the continuous photo film 10.

As shown in FIG. 1, the standard length feed roller 7
0 is rotated by the motor 80, and the teeth formed on the outer periphery thereof mesh with the perforations to convey the continuous photographic film 10. When it is detected by the film feed amount that the leading edge of the continuous photographic film 10 has reached the trimmer 16, the film feeding is stopped and the leading edge of the continuous photographic film 10 is processed by the trimmer 16 and the locking hole 1
0a is formed.

As shown in FIG. 2, in response to a film winding start signal from the controller 14, the sub controller 39 operates the actuator 44 to open and close the shutter 45, and the stacker 33.
One spool 31 is taken out from and loaded into the spool holder 42 located at the first station ST1. After this loading, the sub control unit 39 operates the index device 41 to rotate the spool turret 32 in tact. As a result, the spool holder 42 with the spool 31 set therein is set in the second station ST2. Further, an empty spool holder 42 is set in the first station ST1, and the shutter 4 is set as described above.
One spool 31 is loaded by opening and closing 5. Second
In the station ST2, the sub control unit 39 rotates the motor 43 via the driver 43a and positions the slit 31c of the spool 31 so as to face the radial direction of the spool turret 32 by the spool rotation shaft.

When the spool holder 42 in which the spool has been set is positioned at the third station ST3, the sub control unit 39, as shown in FIG.
Rotate 84. As a result, the standard length feed roller 7
0, rear end feed roller pair 71, insert roller pair 7
2,73 rotate and spool the continuous photo film 10 3
Send to 1. Since the peripheral speed of each roller has a draw ratio, the peripheral speed is slightly increased toward the downstream side, and the continuous photo film 1 is provided between the rollers.
The slack at 0 is prevented.

When the first sensor 97 detects the passage of the leading edge of the film, the sub-control unit 39 opens the lower movable guide plate 89 of the film guide 74 and opens the loop chamber 29 below the film guide 74. Further, when the second sensor 98 detects the passage of the leading end of the film, the sub control unit 39 decelerates the insert motor 84 to cause the insert roller pair 7 to move.
Set the film feed speed by 2,73 to the insert speed. As a result, the free loop of the continuous photo film 10 is gradually formed in the film loop chamber 29.

As shown in FIG. 9, the film tip portion 12b
Is a curved guide surface 9 as it passes through the insert guide 76.
The cross-sectional shape of the film in the width direction is curved into an arc shape by 5a and 96a to form a trough shape, and in this state, the film is inserted into the slit 31c of the spool 31 as shown in FIG. As a result, even if there is insertion resistance when inserting the leading end portion 10b into the slit 31c, the bending rigidity becomes high due to the gutter-shaped cross-sectional shape, so that the continuous photo film 10 does not bend and the insertion into the slit 31c is ensured. To be done.

The slit 3 of the spool 31 is at the tip of the film.
When protruding from 1c, the insert detector 99 detects the film tip 10b. The sub-control unit 39 determines the completion of the insertion from the film leading edge detection signal, stops the rotation of the insert motor 84, and causes the lower movable guide plate 93 of the second film guide 75 to move from the guide position shown in FIG. 8 to the retracted position. As a result, the lower guide block 96 attached to the lower movable guide plate 93 is also set to the retracted position, and the film loop chamber 29 below them is opened.

The control unit 14 includes a rotary encoder 10
The number of pulses from 0 is counted, and when the conveyance amount corresponding to the film size is reached, the completion of the fixed length feeding is detected, and the fixed length feeding completion signal is sent to the sub control unit 39. Sub control unit 39
Stops the driving of the motors 80 and 82 on the basis of the constant-size feed completion signal. After this stop, the control unit 14 operates the trimmer 16 to separate the continuous photographic film 10 into the photographic film pieces 27 and process the leading end and the trailing end. After the operation of the trimmer 16, the sub-control unit 39 rotates the film rear end feeding motor 82 by a fixed amount, and discharges the film rear end 27a from the trimmer 16 into the film loop chamber 29.

After that, the sub control unit 39 operates the index device 41 to rotate the spool turret 32 in tact. After the tact rotation, the sub-control unit 39 turns off the swing solenoid 108, and the continuous photo film 1
Return the feed direction of 0 to horizontal. In addition, each film guide 7
The 4,75 movable guide plates 89, 93 are returned from the retracted position to the guide position.

At the fourth station ST4, the sub-control unit 39 controls the spool 3 to which the film leading end 10b is locked.
1 is rotated to wind the photo film piece 27 in the film loop chamber 29 onto the spool 31. Fifth station S
At T5, the sub control unit 39 causes the wound spool transfer device 3
Spool 31 around which the photo film piece 27 is wound according to 6
Is taken out and sent to the cartridge assembly machine 37.

In the cartridge assembly machine 37, after inserting the spool 31 around which the photographic film piece 27 is wound into the body portion 62, the two caps 64 are attached to the body portion 62 while the spool 31 is rotatably supported. Assemble the photo film cartridge 28 by fitting it on both ends. This photo film cartridge 28 has a rear end portion 27 of the photo film piece 27.
That is, a, that is, a film leader is projected from the cartridge with a constant length regardless of the film size. Less than,
Similarly, the control unit 14 and the sub-control unit 39 operate in synchronism with each other to process the photographic film, wind it on the spool 31, and assemble the cartridge.

When changing the film size, a new film size is input from the setting device 25. The changer 38 changes the cartridge feeder 60 by changing the film size. Also, the side print information is changed. Further, the length of the photo film cut by the trimmer 16 is changed according to the film size. On the other hand, even if the film size is changed, the distance from the trimmer 16 to the spool 31 is set shorter than the film length of the minimum cutting length size.
The basic sequence of the film insert in No. 4 is not changed, and the film feed amount by the constant length feed roller 70 is changed only according to the specified number of photographed photo films. Therefore, it is possible to simplify the control of the film winder that processes a plurality of cut length sizes.

The distance from the center of the trimmer 16 to the center of the spool 31 is, for example, a cutting length size of 740 to 180.
If it is in the range of 0 mm, it should be less than 740 mm. Preferably, it is necessary to set the second film guide 75 to be long according to the shortening of the cycle time. Therefore, the trimmer 1
The distance from 6 to the spool 31 may be set within the range of 500 to 700 mm. Further, the distance from the center of the first insert roller pair 72 to the center of the spool 31, the distance from the first sensor 97 to the second sensor 98, the second sensor 9
The distance from 8 to the center of the spool 31 is determined in consideration of the standard feed speed V1, the deceleration rate α, and the insert speed V2. For example, V1 = 150 [m / min], α =
0.1 [sec / (150 m / min)], V2 = 40 [m
/ Min], and the lower movable guide plate 89 of the first film guide 74 after the leading edge of the film has passed the first sensor 97.
When the time until the film starts to open and does not interfere with the film is 50 [msec], the film advances by 125 mm in the meantime, so the first sensor 97 to the second sensor 98
Distance of up to 125mm or more is required. Further, when the film is decelerated from the standard feed speed V1 to the insert speed V2 at the deceleration rate α, the film advances by 116 mm, so that the distance from the second sensor 98 to the center of the spool 31 is required to be 116 mm or more. In consideration of these, the distance between the first insert roller pair 72 and the second insert roller pair 73 (the length of the second film guide 75) is preferably about 250 mm in the case of the above speed and deceleration rate. Further, the distance from the center of the trim 16 to the center of the spool 31 is shorter than the film length of the minimum cut length size, and the length of the second film guide 75.
Considering the condition that the first film guide 74 should be made as long as possible in consideration of the stabilization of the film loop formation, it is preferable that the speed and the deceleration rate are about 700 mm.

In the above embodiment, the film tip 10b is only inserted into the spool 31 at the third station ST3. However, in addition to this, the film is wound after the insert. Good. In this case, it is not necessary to open the second film guide 75, so a fixed guide may be used. Further, the winding may be performed at two stations instead of at one station. In this case, the cycle time can be shortened by setting the winding amount at each station. Furthermore, spool turret 32
The number of spool holders is not limited to 6, and may be increased or decreased depending on the processing content. Also, the spool 31
However, the present invention is not limited to this, and may be performed at the same work station.

In the above embodiment, the film guide 7 is used.
4, 75 are composed of upper guide plates 88, 92 and lower movable guide plates 89, 93. In addition to this, as shown in FIG. 12, guide grooves 110 for guiding both edges of the continuous photo film 10 are provided. The movable guide 111 having the above may be swingably attached by the attachment shaft 112, the continuous photo film 10 may be guided at the solid line position, and the continuous photo film 10 may be retracted at the two-dot chain line position. The guide rollers 113 may be arranged in the guide groove 110 at an appropriate pitch.

In the above embodiment, the upper pressing roller 106 of the trailing end feed roller pair 71 is replaced by the lower drive roller 1.
Although the deflection of the photographic film loop was oriented by rolling contact with the peripheral surface of No. 05, conversely, the lower roller was rolling contact with the peripheral surface of the upper roller to determine the direction of deflection. It may be performed. Further, in the above embodiment, 35
Although the present invention is applied to a mm photo film, the present invention may also be applied to an advanced photo system type photo film.

According to the first aspect of the present invention, the insert feeding means is provided with film guides for guiding both edges of the photographic film, and first and second portions arranged near both ends of the film guide in the film feeding direction. Since it is composed of a pair of insert rollers, the film feed speed is increased in order to shorten the cycle time, and even if the insert guide becomes longer correspondingly, the film insert is
It can be reliably performed by using individual rollers. Moreover, the tip of the film conveyed at high speed can be surely decelerated and inserted into the spool.

According to the second aspect of the invention, the feeding of the photographic film is started by rotating the fixed length feeding means, the trailing edge feeding means and the insert feeding means, and after the leading edge of the photographic film is detected by the first sensor. The film guide is set from the guide position to the retracted position, the second sensor detects the leading edge of the photo film, and then the film feed speed of the insert feeding means is decelerated to the insert speed, and the insert detector detects the insert of the photo film. After that, the feed of the insert feeding means is stopped, the continuous photo film is fed by the length corresponding to the specified number of shots, and then the feeding of the fixed length feeding means and the trailing edge feeding means is stopped, and then the trimmer is operated. Since the continuous photo film is cut and the trailing edge of the photo film is fed by the trailing edge feeding means after this, depending on the specified number of shots. For different photo film lengths, always with the same procedure can be performed photographic film insert, it is not necessary to perform complicated control such as changing the processing sequence according to the length of the photo film.

According to the third aspect of the present invention, the film rear end portion feeding means is composed of a feed roller pair consisting of a driving roller and a pressing roller, and one of these rollers is decelerated after the insert feeding means is decelerated. Since the feeding direction is changed by displacing the axis of the other roller about the axis, the deflection of the photographic film loop is oriented, so that the loop can be surely formed in the film loop chamber.
Moreover, since the loop is not accidentally formed upward, the photosensitive emulsion surface of the photographic film does not come into contact with the apparatus or the like to be damaged.

Further, the film guide surface of the insert guide is formed in an arc shape in a cross section orthogonal to the film feeding direction, and the leading end portion of the photographic film is curved in a gutter shape and sent to the spool, thereby increasing the bending rigidity of the film. do it,
It is possible to eliminate the film bending and the like at the time of insertion, so that the insertion can be performed reliably.

According to the fourth aspect of the present invention, the insert means is composed of a film guide and first and second insert rollers which are sequentially provided at both ends of the film guide in the film feeding direction. Since the film guide length is set longer along with the increase in the film feeding speed by the length feeding means, the fixed length feeding of the photographic film can be further speeded up, and the cycle time can be shortened.

According to the fifth aspect of the invention, the length from the center of the trimmer to the center of the spool is set to be slightly shorter than the length corresponding to the minimum specified number of shots. Even if the size is changed, the basic sequence does not change, and it is possible to deal with it by simply changing the standard feed amount. Therefore, the control of the photographic film processing apparatus for processing a plurality of cut length sizes is simplified.
