Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image printing condition determining device, and more specifically, it is used in a large-scale developing station by connecting it to a notcher puncher and also when re-ordering an image. The present invention relates to a printing condition determination device (hereinafter referred to as a scanner).

[0002]

2. Description of the Related Art In a large-scale photofinishing laboratory, in order to efficiently carry out photoprinting, a large number of photofilms are connected to each other to make them long and wound up in a roll form. Then, the film is handled in a roll form, the film is developed by a film processor, and then a film check is performed by a notcher puncher. After that, the film is exposed by an auto printer based on the result of the film check.

The above-mentioned film inspection requires skill because the negative image is observed and the exposure correction amount is determined empirically. For this reason, recently, with a notcher puncher or auto notcher, etc., a notch consisting of a semicircular cutout is automatically added to the print target frame, and the scanner automatically detects the frame with this notch. Sometimes the film test is performed.

[0004]

In this case, after connecting the scanner to the existing notcher puncher and automatically making a notch with the notcher puncher, the notcher puncher does not take it up on the reel and the scanner side as it is. It is also possible to automatically determine the exposure correction amount here, but in this case, there is a problem that this scanner cannot be easily used for reorder printing. It is also possible to connect or disconnect the scanner to or from the notcher puncher in consideration of reorder printing, but in this case, the operation to connect or disconnect is required, and the scanner can be easily connected. There is a problem that you cannot use.

Further, when the scanner is simply connected to the existing notcher puncher, it is necessary to match the processing capacity of the notcher puncher with the processing capacity of the scanner, and there is a problem that the connectable models are limited. is there. On the other hand, it is possible to provide a looper that absorbs the processing speed difference between the notcher puncher and the scanner, but simply providing the looper would increase the size of the scanner. Further, there is a problem that the loading of the film takes time due to the looper.

The present invention is for solving the above-mentioned problems, and can be easily connected to an existing notcher puncher, and even if the processing capacity is different, it can be connected. It is an object of the present invention to provide an image print condition determining device that can be easily performed.

[0007]

In order to achieve the above object, the invention described in claim 1 provides a first film feeding means provided on the upstream side of the film feeding of the photometric means, and a film feeding downstream of the photometric means. Second film feeding means provided on the side, dancer rollers provided on the first film feeding means, and displacing means for displacing the dancer roller between a film drawing position and a loop forming position after drawing the film. A first film detecting means provided at an insertion opening of the photo film for detecting a film leading edge, a second film detecting means for detecting a film leading edge of the second film feeding means, and a dancer roller at initial setting Is set to the film drawing position, and when the first film detecting means detects the leading edge of the film, the first and second film feeding means are rotated, The first and second film feeding means are rotated by a fixed amount based on the film leading edge detection signal of the second film detecting means and then stopped to feed the leading edge of the film to the film winding means, after which the first film feeding means is in a free state. In addition to the above, the control means is provided to displace the dancer roller toward the loop forming position.

According to the second aspect of the invention, the light source of the photometric means is turned on when the first film detecting means detects the leading edge of the film.

According to the third aspect of the present invention, the notch detecting means is constituted by a light receiving sensor, and when the film detecting means detects the leading edge of the film, the light is received in a state where the film does not block the optical axis of the sensor. The sensitivity level of the light receiving sensor is adjusted based on the sensor signal.

[0010]

[Operation] Connect the scanner to the notcher puncher. At the time of initial setting with the power turned on, the dancer roller is set to the film drawing position. When printing at the same time, insert the photo film from the notcher puncher into the film slot of the scanner. As a result, the first film detecting means detects the leading end of the film, and thereby rotates the first and second film feeding means provided on the upstream and downstream sides of the photometric means for feeding the film. When the film has passed the photometric means and the leading edge of the film has been detected by the second film detecting means, the first and second film feeding means are fixedly rotated based on this film leading edge detection signal, and then stop. As a result, the leading end of the film is sent to the film winding means. After the leading end of the film has been set on the film winding means, the first film feeding means becomes free and the second film feeding means feeds the film. Also, the dancer roller is set to the loop forming position.

When the notch detecting means detects a notch, the print target frame is set at the photometric position based on the detection signal, and the respective points of the print target frame are subjected to three-color separated photometry by the photometric means. Then, based on the photometric value, LAT
The exposure correction data is calculated in the form of a difference with respect to D, and this is written together with the frame position data in a recording medium, for example, an LSI card.

Further, when the first film detection sensor detects the leading edge of the film, the light source is turned on, whereby the illumination light of the light source is stable and stable by the time the frame to be printed is set at the print position. It can be measured under the illumination light. Further, since the light source is not turned on until the leading end of the film is inserted into the film insertion opening, no unnecessary power is consumed.

When the leading edge of the film is detected by the first film detecting sensor, the sensitivity level of the light receiving sensor is adjusted based on the signal from the light receiving sensor of the notch detecting means without the film blocking the sensor optical axis. Done. As described above, since the sensitivity level is adjusted every time the leading end of the film is inserted, the notch detection accuracy does not vary.

Further, the dancer roller operates to absorb the difference in film feed speed between the notcher puncher and the scanner. Further, the operations of the notcher puncher and the scanner are controlled according to the loop amount by the dancer roller, and the processing speed difference between them is absorbed.

In 58, the first and second feed roller pairs 56, 57
Sends the film 20 during auto loading. Also, the third
The feed roller pair 58 is used for frame feeding for feeding the photometric target frame to the photometric stage 70 after auto loading. Therefore, as shown in FIG. 5, the third feed roller pair 58 is always linked to the film feed motor 72 via the timing belt 71. Further, the drive rollers 56a and 57a of the first and second feed roller pairs 56 and 57 are
It is connected to the clutch mechanism 76 via the timing belt 73 and gears 74 and 75. Since the clutch mechanism 76 transmits the drive of the timing belt 71 to the timing belt 73 only during auto loading, the first and second feed roller pairs 56 and 57 are rotated only during auto loading.

The clutch mechanism 76 includes a planetary gear train 80 and
It is composed of a clutch arm 81 and a clutch lever 82. The planetary gear train 80 includes a drive gear 80a, a planetary gear 80b, and a sun gear 80c. The drive gear 80a is fixed coaxially with the drive roller 58a of the frame feed roller pair 58. Sun gear 80c

The clutch lever 82 is biased counterclockwise in the figure by a coil spring 84, and the clutch arm 81 is biased counterclockwise in the figure by a coil spring 85. Coil spring 84 for clutch lever 82
Has a stronger urging force than the coil spring 85 for the clutch arm 81, so that the planet gear 80b is normally separated from the drive gear 80a. Further, during auto loading, the dancer roller 64 is set to the auto loading position, which causes the clutch lever 82 to rotate clockwise as shown in FIG. Therefore, the clutch arm 81 rotates counterclockwise in the figure by the bias of the coil spring 85, and the planet gear 80b meshes with the drive gear 80a. As a result, the feed roller pairs 56 and 57 rotate during auto loading, and the leading end of the film 20 is auto loaded.

Further, the driven rollers 56b and 57b of the feed roller pair 56 and 57 are attached to the drive rollers 56a and 57a via the arms 56c and 57c so as to be in contact with or separated from the drive rollers 56a and 57a. The arms 56c and 57c and the dancer arms 61 and 65 are rotationally controlled by an automatic load setting mechanism 86.

The auto load set mechanism 86 rotates the arms 56c and 57c and the dancer arms 61 and 65 by the auto load set motor 88 to show the feed roller pairs 56 and 57 and the dancer rollers 60 and 64 in FIG. Displacement is possible between the autoload position and the dancer loop forming position shown in FIG. The auto load set motor 88 is controlled by the controller 24 via the driver 88a.

In the autoload position, the drive roller 56
Since the driven rollers 56b and 57b come into contact with the a and 57a, the film 20 is nipped and conveyed by the feed roller pairs 56, 57 and 58. After the autoloading is completed, the automatic load setting mechanism 86 stops pushing the arms 56c, 57c, 61, 65.
As a result, the arms 56c, 57c, 61, 65 are urged toward the dancer loop forming position by the springs 56d, 57d, 62, 66. On the dancer loop forming position side, the nip of the auto-loading feed roller pair 56, 57 is released, so that the film 20 is conveyed only by the film feed roller pair 58. Further, the dancer arms 61 and 65 are urged toward the dancer loop forming position side by the coil springs 62 and 66. Therefore, when a speed difference occurs in the film feed on the upstream side and the downstream side of each dancer roller 60, 64, dancer loops 63, 67 are formed as shown in FIG.

As shown in FIGS. 5 to 7, the automatic load setting mechanism 86 includes a timing belt 89 rotated by an automatic load setting motor 88 and a rotating disk 9.

When the timing belt 89 is rotated, the pushing pins 90a and 91a are located at the autoload setting positions shown in FIGS. It is arranged to be displaced between the loop forming position shown in FIG. At the autoload position, the push pins 90a and 91a are used to move the arms 61 and 6 respectively.
5 is set to the autoload position. Further, at the loop forming position, the push pins 90a and 91a are retracted positions in which the respective arms are not pushed.

As shown in FIGS. 6 and 7, the cam lever 9
2 is fixed coaxially with the disc 90 on the side of the first dancer arm 61, and this cam lever 92 engages with the engagement pin 93a of the slide plate 93 to move the slide plate 93 in parallel. On the slide plate 93, first and second push pins 93b and 93c are provided so as to project at positions where they are engaged with the roller arms 94 and 95 of the first and second feed roller pairs 56 and 57. The slide plate 93 is a coil spring 93d.
Is biased toward the autoload position. Then, at the time of automatic loading, the cam lever 92 does not engage with the slide plate 93, so that the positions are as shown in FIG. The film 20 is nipped by the pair of feed rollers 56 and 57 and is automatically loaded.

After the autoloading, the autoload motor 88 rotates in the forward direction to rotate the disks 90 and 91 and the cam lever 92 clockwise to set them to the loop forming position as shown in FIGS. At the loop forming position, the push pins 90a and 91a are displaced to the retracted position and the dancer arm 6
Allows a displacement of 1,65. As a result, when a difference occurs in the film feed speeds on the upstream side and the downstream side of the dancer rollers 60, 64, loops 63, 67 are formed by the displacement of the dancer arms 61, 65.

When the cam lever 92 is displaced to the loop forming position, as shown in FIG. 7, the cam lever 92 pushes the engaging pin 93a to displace the slide plate 93 upward. As a result, L is pushed through the push pins 93b and 93c.
The mold arms 94 and 95 rotate to separate the driven rollers 56b and 57b of the auto load feed roller pair 56 and 57 from the drive rollers 56a and 56a. As a result, the feed roller pair 5
The film is not fed by 6, 57, and the film is fed frame by frame only by the film feed roller pair 58. Since the film nip is released in this way, the feed resistance during frame feeding is reduced.

As shown in FIG. 4, the third feed roller pair 58

It can be automatically switched. The frame size information can be automatically detected by a frame size sensor, in addition to the frame size designation information from the notcher puncher. Further, it is also possible to use the frame size information recorded on the magnetic recording layer of the film.

The light illuminated by the light source unit 13 and transmitted through the frame to be measured is reflected by the half mirror 105 and sent to the scanner body 108 composed of an image area sensor via the zoom lens 107. The scanner body 108 performs three-color separated photometry on each point of the photometry target frame. The correction data calculation unit 109 calculates correction data in the form of a difference from LATD based on the photometric value. In the correction data calculation process, the print target frames are classified into various scenes by statistical processing based on the three-color separation photometric value of each point, and the exposure correction data is determined according to the classified scenes. The LSI card reader / writer 110 writes the correction data in the LSI card 35 in association with the frame position data.

The light transmitted through the half mirror 105 is reflected by the mirror 111. As a result, the photometry target frame can be observed through the negative viewing window 19. By this observation, the stop position of the photometry target frame can be confirmed and adjusted by the upper cover 1
It becomes possible without opening 6. Further, the external light from the negative viewing window 19 is reflected by the mirror 111 and then reflected upward by the half mirror 105 or transmitted through the half mirror 105 toward the light source side.
Since the light does not enter at 08, it is not affected by this at the time of photometry.

As shown in FIG. 1, the film transport path 12 has a film sensor 12 for detecting the leading edge of the film.
0, 121, a splice sensor 122 for detecting the splice portion of the film 20, and a notch sensor 123 for detecting the notch of the film 20 are provided in this order, and these detection signals are sent to the controller 24.

In the reorder printing process, the film piece 1 for reorder printing is printed by the well-known film splicer 150.
51 is joined and lengthened, and this is wound around the take-up reel 48 to form a film roll. At the same time as the joining, the designation of the frame position of the reordered print frame and the number of prints are input by the operator, and this is written in the LSI card 35. Then, the reordered film 47 and the LSI card 35, which are wound into a roll, are set in the scanner 10 of the present invention.

As shown in FIG. 3, the sub reel mounting portion 40
When is pulled out from the case main body 11, the reel mounting flange 45a is lifted to the level of the film transport path 12, and this state is maintained. After setting the reel 48 in which the reordered film 47 is wound around the reel mounting shaft 45, and inserting the leading end of the film 47 into the film insertion opening 17, the autoloading is started as in the simultaneous printing process, and the film is loaded. Exits from the film exit 18. When the tip of the film 20 is manually wound around the film take-up reel 23, the autoloading is completed. After that, the position data of the reordered frame recorded in the LSI card 35 is read, and the reordered frame is measured on the photometric stage based on the position data, the notch detection count number of the notch sensor, and the splice portion detection signal of the splice sensor. To position. After that, the reordered frame is measured, and the exposure correction data is calculated based on the photometry, and this correction data is written in the LSI card 35 together with the frame position data.

FIG. 12 is a flow chart showing the procedure of automatic loading in the controller 24. Also,
FIG. 13 is a flowchart showing photometry processing after autoloading and operation control of the notcher puncher 41 and the scanner 10 depending on the loop amount.

Next, referring to FIGS. 12 and 13,
The operation of this embodiment will be described. In use, the developed film roll 131 is set on the notcher puncher 41 and loaded, and then the leading end of the film 20 is inserted into the film insertion opening 17 of the scanner 10. In the notcher puncher 41, the film 20
A notch is formed at the position of the frame to be printed at one of the side edges, and exposure correction data is input as necessary. The film 20 that has passed through the notcher puncher 41
When the tip of the scanner is inserted into the film insertion opening 17 of the scanner 10, the scanner 10 starts autoloading as shown in FIG. 12, and also performs various initial settings.

That is, as shown in FIG. 1, the leading end of the film 20 is inserted into the guide roller pair 50, and the leading end thereof is the first.
When detected by the film sensor 120, the light source unit 13
(See FIGS. 1 and 8) is turned on. Therefore, when the frame to be measured is positioned on the photometric stage 70, the light source unit 13 emits stable light, and the stable illumination light allows the scanner body 108 to perform photometry.
Further, when the first film sensor 120 is turned on, the light amount of the notch sensor 123 in the absence of film is detected,
Based on this, the sensitivity level of the notch sensor 123 is automatically adjusted.

In the initial setting state of the scanner 10, FIG.
As shown in FIG. 5, the auto load setting mechanism 86 is operated, and the dancer rollers 60 and 64 are set to the auto load position by the push pins 90a and 91a of the push disks 90 and 91. In this autoloading position, the first and second dancer rollers 60, 64 have entered the film transport path 12 to pull out the film 20 and form a loop. Further, as shown in FIGS. 1 and 6, the cam lever 92 also rotates together with the pushing disc 90, and the engagement pin 9
The guide roller pair 56, 57 is in a state of nipping the film by the bias of the coil springs 56d, 57d because it is in a position where it does not come into contact with 3a.

When the first film sensor 120 is turned on, the film transporting motor 77 is rotated, so that the leading end of the film 20 is first nipped by the first feed roller pair 56. The leading end of the film 20 is guided by the guide plate 59 and other guide plates, and is fed by the pair of feed rollers 56 and 57 to pass the photometric stage 70, and then the film exit 18
Reach

When the second film sensor 121 detects the leading edge of the film, the film winding motor 21 rotates. Then, the leading end of the film 20 exiting from the film outlet 18 is manually wound around the winding reel 23 of the film winding section 15. As shown in FIG. 12, when the film winding is completed, the load of the motor 21 of the film winding section 15 is increased. Therefore, the controller 24 detects this and stops the rotation of the film winding section 15, and the automatic load Detect completion. After this is completed, the auto load set motor 88 rotates to rotate the disks 90, 91 clockwise in the drawing. By the rotation of the disks 90 and 91, the push pins 90a and 91a are retracted to positions where they do not hit the dancer arms 61 and 65, respectively. As a result, the dancer arms 61 and 65 are rotatable, and the dancer loop can be formed.

When the notch sensor 123 detects the notch of the film 20, the frame to be printed is set on the photometric stage 70 based on this detection signal. Further, the rotation of the mask turret 104 is controlled based on the frame size information from the notcher puncher 41, and the photometric stage 70
A mask opening that matches the frame size of the frame to be printed is set. Thereafter, as shown in FIG. 8, the scanner main body 108 photometrically separates each point of the frame, and the correction data calculation unit 109 calculates the exposure correction data based on the photometric value. This exposure correction data is obtained based on LATD, and this is stored in the LSI card 35 together with the frame position data by the LSI card reader / writer 110.

If there is a difference between the processing speed of the notcher puncher 41 and the processing speed of the scanner 10,
As shown in FIG. 4, the speed difference is absorbed by the formation of the loop 63 by the first dancer roller 60. Further, as shown in FIG. 9, when the loop amount of the dancer roller 60 becomes a predetermined amount or less and the first loop sensor S1 is turned on, the film feeding for photometry is stopped. When the loop amount of the dancer roller 60 exceeds the predetermined amount and the second loop sensor S2 is turned on, a busy signal is sent to the notcher puncher 41 and the film feeding on the notcher puncher 41 side is stopped.

The film winding section 15 operates when the loop amount of the second dancer roller exceeds a predetermined amount, and winds the film so that the loop amount is reduced. Then, when the loop amount becomes equal to or less than the predetermined amount, this winding is finished.

In the case of reorder printing, the sub reel mounting portion 40 is pulled out from the case body 11 as shown in FIG. By this drawing, the reel mounting flange 45a is lifted to the level of the film transport path 12, and this state is maintained. After setting the reel 48 in which the reordered film 47 is wound around the reel mounting shaft 45, and inserting the leading end of the film 47 into the film insertion opening 17, the autoloading is started as in the simultaneous printing process, and the film is loaded. The tip of the film exits from the film exit. When the leading end of the film is manually wound around the film take-up reel 23, the auto loading is completed. After that, the reordered frame recorded in the LSI card 35 is positioned on the photometric stage, only this reordered frame is photometered, and the exposure correction data of this is written in the LSI card 35.

After the photometry is finished, the films 20 and 47 are removed from the film winding section 15, and as shown in FIG. 11, they are set together with the LSI card 35 in the auto printer 160 which is the next step. Instead of directly setting the films 20 and 47 removed from the film winding section 15 in the auto printer 160, as shown in FIG. 3, the sub reel attaching section 40 is pulled out from the case main body 11 and an empty reel is attached to the sub reel attaching section 40. Set, and rewind the photometered film to this empty reel, and then rewind the film to the auto printer 1
You may make it set to 60.

In the above embodiment, the film feed at the time of automatic loading was performed by the film feed roller pair.
This may be done by a pair of conveyor belts. Further, in the above embodiment, the clutch mechanism is composed of the planetary gear train, and the clutch mechanism is mechanically turned on and off by the displacement of the second dancer roller to simplify the electrical control. May be electrically performed by an electromagnetic clutch or the like. Further, after the film is automatically loaded by the auto load setting mechanism 86, the film nip of the film feed roller pair 56, 57 is released,
Although the frame feed load of the film is reduced, this may be achieved by simply setting the feed roller pair in a free state.

[0065]

As described above, according to the present invention,
At the time of initialization, the dancer roller is set to the film pull-out position, and when the first film detecting means detects the leading edge of the film, the first and second film feeding means are rotated, so that the first and second film are rotated. The leading end of the film can be automatically loaded by the feeding means. Further, when the second film detecting means detects the leading edge of the film, the film feeding of the first film feeding means is stopped to make it free, and the dancer roller can be displaced to the loop forming position side. After autoloading, the dancer roller can absorb the difference in processing speed and film feed speed between the notcher puncher and the scanner. Therefore, photometry with the scanner can be smoothly performed.

Since the light source of the photometric means is turned on when the first film detecting means detects the leading edge of the film, the illumination light of the light source is stabilized by the time the frame to be printed is set at the print position. Can be measured under stable illumination light. Further, since the light source is not turned on until the leading end of the film is inserted into the film insertion opening, no unnecessary power is consumed.

Further, the notch detecting means is constituted by a light receiving sensor, and when the film detecting means detects the leading edge of the film, the sensitivity of the light receiving sensor is detected based on the signal of the light receiving sensor in a state where the film does not block the sensor optical axis. Since the level is adjusted, the sensitivity level is adjusted every time the tip of the film is inserted, so that the notch detection accuracy does not vary.
