DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of an image recording apparatus for cutting a roll-shaped long photosensitive material into a predetermined length and printing an image of a photographic film on the cut photosensitive material.

[0002]

2. Description of the Related Art In recent years, a printing apparatus using digital exposure, that is, an image recorded on a photographic film (hereinafter, referred to as a film) such as a negative film or a reversal film is photoelectrically read, and the read image is digitally read. After the signal, a variety of image processing is performed to produce image data for recording, and a recording material modulated according to the image data scans and exposes a photosensitive material such as photographic paper to record an image (latent image). 2. Description of the Related Art Digital photo printers that perform development processing and output prints (photographs) have been put to practical use.

In a digital photo printer, an exposure condition is determined by photoelectrically reading a film and performing gradation correction and the like by image (signal) processing. Therefore, it is possible to freely perform editing of a print image such as synthesis of a plurality of images by image processing and image division, and various image processing such as color / density adjustment and contour enhancement. Can be output. Further, the image data of the print image can be supplied to a computer or the like, and can be stored in a recording medium such as a floppy disk. Furthermore, compared to conventional direct exposure printing,
It is possible to output a print with better image quality, which is excellent in resolution, color / density reproducibility, and the like.

Such a digital photo printer basically includes an input device having a scanner (image reading device) and an image processing device, and an output device having a printing device and a developing device.

By the way, in a printing apparatus, for each photograph (one finished print), various kinds of information relating to printing, for example, a frame number, a film number, a photographing date of a photographic film, and printing of a film image on a photosensitive material. A so-called back print is performed in which various information (hereinafter, referred to as back print information) such as a date such as a date, a code of a development laboratory (lab) and other data is recorded on the back side (non-exposed side) of the print. It is common. In addition, a recently announced new standard for photography, the Advanced PhotoSyste
In m), the backprint is standardized to two lines or more with 40 characters or more per line, and according to the magnetic information recorded on the film, in addition to information such as the shooting date, "travel", "graduation ceremony" Titles such as "birthday" are set so that they can be recorded as back prints.

However, when the back-printed photosensitive material is subsequently nipped and conveyed by the conveying rollers, there is a problem that the back print may rub against the conveying rollers and the back surface of the photosensitive material may be stained. For this reason, in a conventional image recording apparatus, as shown in FIG. 5, for example, as shown in FIG. 5, a transport roller 132 in contact with the back surface of the photosensitive material is configured as a split roller in the transport unit 130 after back printing is performed. The gap 132 between the split rollers
A is configured so that the back print recorded in the conveyance direction passes through the photosensitive material, so that the photosensitive material is conveyed without directly contacting the back print and the conveyance roller, thereby preventing the back print from being stained.

[0007]

By the way, in a cut sheet type image recording apparatus, the photosensitive material is sorted in a horizontal direction to form a plurality of rows, so that the processing capacity of a developing machine is improved. If it is, it is possible to perform less than twice the processing of a single row, and if it is three rows, it is possible to perform processing of less than three times
It is conceivable that the processing time difference between the development processing and the exposure is offset to greatly improve the print production capacity.

As one of means for distributing the photosensitive material as described above, a configuration in which the photosensitive material is rotated 90 degrees to the right and left by a rotary moving means such as a turret and moved to perform an efficient distributing process can be considered. However, when such a configuration is adopted, the direction of the character string of the back print recorded in the transport direction is changed by 90 degrees, and the back print cannot be sufficiently released only by the gap between the divided rollers. There's a problem. That is, when the photosensitive material is rotated by 90 degrees and sorted, the character string of the back print is arranged in a direction parallel to the transport roller.
For this reason, in order to avoid contact between the split roller and the back print, it is necessary to configure the gap between the split rollers so as to secure the length of the character string of the back print. There is a problem that the width of the divided rollers to be sandwiched is significantly limited, and the function as a transport roller pair cannot be sufficiently secured.

The present invention has been made in view of the above circumstances, and supplies a sheet-shaped photosensitive material obtained by cutting a long roll-shaped photosensitive material stored in a magazine into a predetermined length.
Provided is an image recording apparatus for printing an image of a photographic film on the photosensitive material, which is capable of obtaining a print in which a back print is clearly recorded, while significantly improving the production capacity of the print. As an issue.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an image recording apparatus according to the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

FIG. 1 shows a basic configuration of an image recording apparatus to which the present invention is applied. Image recording apparatus 10 shown in FIG.
(Hereinafter, referred to as a recording apparatus 10) is cut into a predetermined length corresponding to a print for producing a long photosensitive material, cut into a cut sheet, and then back-printed (back-printed) and digitally exposed. The apparatus supplies the photosensitive material Z to a developing machine (processor), and includes a photosensitive material supply unit 12, a back printing unit 14, a recording unit 52, and a sorting unit 18. Although not shown in order to clarify the basic configuration of the apparatus, the recording apparatus 10 includes a conveyance unit such as a conveyance roller, a conveyance guide for the photosensitive material Z, a sensor for detecting the photosensitive material, and the like. Various members arranged in a known image recording apparatus are arranged as necessary. Here, the interval between the conveying rollers provided as the conveying means is set smaller than the minimum length of the sheet-shaped photosensitive material Z after cutting so as not to hinder the conveyance of the photosensitive material Z.

The photosensitive material supply section 12 has magazines 20 and 2 in which a long photosensitive material Z wound in a roll shape with the emulsion surface (photosensitive surface) outside is housed in a light-shielding housing.
The loading unit 54 is loaded with the drawer roller pair 24, the loading unit 56 is loaded with the drawer roller pair 26, and the loading unit 54 is loaded with the cutter 28a. The cutter 28b corresponding to the part 56
Are disposed adjacent to the downstream side of the pull-out roller pairs 24 and 26, respectively.

The recording apparatus 10 in the illustrated example is an apparatus capable of loading two magazines 20 and 22. Both apparatuses generally have a size (width), a surface type (silk or mat), and a specification (thickness, base type, etc.). ), Etc., are stored. In the recording device 10 of the present invention, the number of magazines that can be loaded is not limited to two in the illustrated example, and may be one, or three or more magazines may be loaded. Is also good.

In such a photosensitive material supply section 12, a corresponding roll of photosensitive material Z of a magazine is drawn out by a pair of draw-out rollers 24 and 26 and transported downstream. This conveyance stops when the photosensitive material Z conveyed downstream of the cutters 28a and 28b has a length corresponding to the size of the image to be recorded.
8a and 28b are operated to turn the photosensitive material Z into a cut sheet having a predetermined length.

In the recording apparatus 10 shown in FIG. 1, cutters 28a and 28b are provided for each of the two magazines 20 and 22, and the photosensitive material Z drawn from these magazines is separated by separate cutters 28a and 28b, respectively. Although the cutting is performed, the present invention is not limited to this, and the cutting may be performed by one common cutter.
The sheet-shaped photosensitive material Z drawn out from the photosensitive material supply unit 12 and cut as described above is conveyed to the back printing unit 14.

The back printing section 14 includes a photographing date, a print printing date,
Various information such as a frame number, a film ID number (code), an ID number of a camera used for photographing, and an ID number of a photo printer, a so-called back print (back print). Such a back printing unit 14 is, for example, a dot impact type printer 58 as a contact type printing device.
The back print is recorded on the photosensitive material Z which is guided and conveyed by the guide 60, but the recording method (printer) of the back print is not limited to this, and a known method such as an ink jet printer, a thermal transfer printer, or the like is used. Various back print recording methods used in photo printers are available. Further, it is preferable that the back printing unit 14 is configured to be capable of printing two or more lines in accordance with a new standard new photo system (Advanced Photo System).

The back printing section 14 can be arranged before or after exposure as long as it is on the upstream side of the sorting section 18 in the transport direction. This is because, if it is arranged downstream of the distribution unit 18 in the transport direction, it is necessary to provide at least two back printers according to the distribution line. Further, it is preferable to dispose the back printing unit 14 on the upstream side in the transport direction of the recording unit 52. In this case, the back printing unit 14 is formed by the photosensitive material supply unit 12, the cutters 28a and 28b, the recording unit 52, and the transport path interposed therebetween. The used empty space can be used effectively, the transport path on the downstream side of the recording unit 52 can be simplified, and the space can be saved. The photosensitive material Z cut to a predetermined length and back-printed in this manner is then transported to the recording unit 52 (sub-scan transport unit 62).

The recording section 52 includes an exposure optical unit (hereinafter, referred to as an exposure optical unit).
Exposure unit 16) and sub-scanning conveyance means 62. In the illustrated example, the image recording by the exposure unit 16 is modulated in accordance with digital image data while scanning and transporting the sheet-like photosensitive material Z.
By using a light beam deflected in a main scanning direction (perpendicular to the plane of FIG. 1) perpendicular to the scanning and transporting direction as a recording light L, a photosensitive material Z is exposed at a recording (exposure) position X by so-called digital scanning exposure. Done.

The exposure unit 16 is an optical unit for performing such digital exposure.
A light source that emits light beams corresponding to red (R) exposure, green (G) exposure, and blue (B) exposure, and an AOM that modulates the light beam emitted from the light source according to digital image data Modulation means such as an acousto-optic modulator), an optical deflector such as a polygon mirror which deflects the modulated light beam in a main scanning direction orthogonal to the scanning and conveying direction, and a light beam deflected in the main scanning direction at a recording position X. This is a known light beam scanning device that includes an fθ (scanning) lens or the like that forms an image at a predetermined position on a (scanning line) with a predetermined beam system.

The exposure unit 16 is not limited to such a light beam scanning device, but is a digital exposure means using various light emitting arrays or spatial modulation element arrays extending in a direction orthogonal to the scanning and conveying direction. Are available. Specifically, a PDP (plasma display) array, an ELD (electroluminescent display) array, an LED (light emitting diode) array, an LCD (liquid crystal display) array, a DMD (digital micromirror device) array, a digital using a laser array, or the like. Exposure means is exemplified.

The sub-scanning conveyance means 62 has a pair of conveyance rollers 64 and 66 disposed so as to sandwich the recording position X (scanning line), and an exposure conveyance guide 68. While holding the sheet-shaped photosensitive material Z at the recording position X, the photosensitive material Z is transported by the transport roller pairs 64 and 66 in the sub-scanning direction orthogonal to the main scanning direction. Here, as described above, since the light beam is deflected in the main scanning direction, the photosensitive material Z is two-dimensionally scanned and exposed by the light beam to form a latent image.

There is no particular limitation on the scanning / conveying means used in the recording apparatus 10 of the present invention, and various conveying means used for known digital scanning exposure are exemplified. Specifically, in addition to the scanning and conveying means using a pair of conveying rollers disposed so as to sandwich the recording position X (scanning line), an exposure drum for conveying the photosensitive material Z while holding it at the recording position X; Scanning and conveying means using two nip rollers abutting on the exposure drum across the recording position X, scanning and conveying means including an endless belt and two nip rollers, and scanning and conveying means including only an endless belt are preferably exemplified. . The photosensitive material Z thus exposed is distributed to the sorting unit 1
8.

The sorting section 18 is a sheet-shaped photosensitive material Z
In the direction orthogonal to the transport direction, and is provided substantially horizontally in the transport path downstream of the recording unit 52 and upstream of the developing device 72. At present, in general silver halide photographic light-sensitive materials used for photographic printing, development processing and exposure require more time for development processing. Therefore, if exposure is performed continuously, development processing cannot be completed in time. The sorting unit 18 is arranged to solve this inconvenience. The sorting unit 18 sorts the photosensitive material Z in the horizontal direction and divides the photosensitive material Z into a plurality of rows in a direction orthogonal to the transport direction, so that the processing in the photosensitive material processing device 72 is performed. It is possible to improve the performance, for example, it is possible to perform the processing of less than twice the single row in the case of two rows and less than three times in the case of three rows, and to offset the processing time difference between the development processing and the exposure.

Also, even when the photosensitive material Z passes from the front to the transport rollers provided in multiple stages in the developing machine 72, the relatively rough photosensitive material Z caused by cutting by the cutters 28a and 28b is used. Since the cut surface does not collide with the roller surface, it is possible to prevent the cut surface from deteriorating and prevent so-called seepage of the photosensitive material Z from infiltration of the developer or the like from the leading end of the photosensitive material Z. further,
Since the sheet-shaped photosensitive material Z cut vertically in the conveying direction is rotated 90 degrees and conveyed horizontally in the conveying direction, the conveying speed is reduced on the downstream side of the sorting unit 18 to reduce the photosensitive speed. If the interval for each material Z is reduced, the processing capacity of the developing machine 72 can be further improved.

FIG. 2 shows a conceptual diagram of the distribution processing by the distribution unit 18. The distribution unit 18 in the illustrated example includes a turret 80, a driving source 90, and a moving unit (not illustrated). The turret 80 is a rotary plate on which the photosensitive material Z conveyed from the recording unit 52 is placed, and is configured to be rotatable by 90 degrees in both the left and right directions. (Corresponding to the transport direction of the machine) and is supplied to the downstream transport path 100 after being sorted into two rows in a direction orthogonal to the transport direction. For this reason, a rotating shaft 92 is provided at the center of the turret 80, and a drive source 90 is provided via the rotating shaft 92, so that the turret 80 is configured to be rotatable in the horizontal direction. Note that the shape of the turret 80 is not limited to the disk shape in the illustrated example, and is not particularly limited as long as it has a surface on which the photosensitive material Z can be placed, and members having various shapes can be used. The drive source 90 is not particularly limited, and various conventionally known motors and the like can be used.
The drive source 90 may be directly connected to the rotating shaft 92, or may be connected to a gear or a pulley via a transmission means such as a belt.

In the sorting process in the sorting section 18, the photosensitive material Z conveyed is transferred to the turret 80.
Each time the turret 80 is ejected and placed on the upper side, the turret 80 is rotated by 90 degrees in either direction to the left or right, and two rows of a row A positioned as the right side of the downstream transport path and a row B positioned as the left side of the downstream transport path. In this case, it may be performed by disposing the photosensitive material Z at a position corresponding to a desired column. For example, the rotation direction of the turret 80 is alternately reversed each time the conveyed photosensitive material Z is placed, so that the photosensitive materials Z are sequentially arranged in row A,
It is sufficient to adopt a configuration in which the data is alternately divided into two rows, such as row B, row A, and so on.

Here, when the rear end of the sheet-like photosensitive material Z is discharged from the pair of transport rollers 84 immediately before the sorting section 18, the photosensitive material Z is placed on an appropriate position on the turret 80. Is preferred. For this, for example,
When the rear end of the photosensitive material Z is discharged from the pair of conveying rollers 84, a rod-shaped or plate-shaped contact member is driven to come into contact with the rear end of the photosensitive material Z, and the turret 8
It may be configured to move to an appropriate position on zero. When the photosensitive material Z is discharged to the turret 80,
The suction cup adsorbs the photosensitive material Z from above and moves the photosensitive material Z to an appropriate position, or a transport roller is provided above the turret 80, and rotates by contacting the photosensitive material Z discharged onto the turret 80 from above. The photosensitive material Z may be moved to an appropriate position by driving. Further, a configuration in which a transport roller is provided on the surface of the turret 80, or a transport roller is provided above the surface of the turret 80 and above the turret 80 to form a pair of transport rollers, and the position of the photosensitive material Z may be adjusted.

Also, after the photosensitive material Z is distributed, similarly to the above, the driving of the contact member, the suction by the suction cup, the driving of the transport roller above the turret 80, the turret 80
By moving the leading end of the photosensitive material Z to the downstream conveying roller pair 104 and nipping it by moving means such as driving the conveying roller on the front surface or driving the conveying roller pair, the conveying to the downstream side can be efficiently performed. It can be carried out. The moving means for moving the photosensitive material Z placed on the turret 80 in this way is not limited to the above example, and various conventionally known methods can be used.

Further, in the image recording apparatus 10, the photosensitive material Z of all sizes is not necessarily arranged in two rows, and the photosensitive material Z of a large size that cannot be processed in a plurality of rows is used.
The developer may be carried into the developing machine 72 in a single row without distribution, and in this case, the turret 80 is not rotated (rotation angle is 0 degree) or the rotation angle is set to 180 degrees so that the distribution unit 18 is moved. What is necessary is just to make it the structure which passes. Further, when the distribution is performed, the configuration may be such that the distribution is performed according to the size of the photosensitive material Z, instead of allocating all the sizes in the same number sequence.

In the sorting unit 18, 2
The row of photosensitive materials Z is supplied to the developing machine 72 by the transport roller pair 104. In the developing machine 72,
For example, in the case of developing a silver halide photographic light-sensitive material, a latent image is developed by performing a predetermined developing process according to the light-sensitive material Z such as a color developing tank, a bleach-fixing tank, and a washing tank, and then dried. The prints are finished prints, are again stacked in a single line in the order of print creation (exposure order), and are discharged to a sorter or the like.

Here, in such an image recording apparatus, as the photosensitive material on which the back print has been performed is nipped and transported by the transport roller, the back print may rub against the transport roller and the back surface of the photosensitive material may be stained. There was a problem. For this reason, conventionally, in the conveying means after the back printing is performed, the conveying roller in contact with the back surface of the photosensitive material is a divided roller, and the back print is released from a gap between the divided rollers, The back print was prevented from being stained.

However, as described above, when the sorting is performed by rotating the photosensitive material 90 degrees left and right, the direction of the back print character string recorded in the transport direction is changed by 90 degrees. There is a problem in that the back print cannot be sufficiently released only by the gap between the divided rollers because the paper is arranged in parallel with the transport roller.

Therefore, in the image recording apparatus of the present invention, in the conveying means having a conveying roller pair including a driving roller and a driven roller and a control unit, the driving roller on the downstream side of the distribution unit is provided on the outer peripheral surface thereof. When one or more concave portions are formed in the direction of the rotation axis, the back print printed on the back surface of the photosensitive material is rotated by 90 degrees when the photosensitive material is distributed by 90 degrees. The above problem is solved by controlling the driving of the driving roller so as to pass through.

More specifically, as shown in FIG. 3 and FIG. 4, the downstream transport means 100 has a guide 102, a transport roller pair 104, and a control unit 116. FIG. 4 also shows an example of the photosensitive material Z sorted by the sorting unit 18.

The guide 102 guides the sheet-shaped photosensitive material Z to the next pair of transport rollers 104.
As in the illustrated example, the guide 102 may be formed in a flat plate shape, and a pair of transport rollers 104, 104 may be provided at both ends thereof. Alternatively, a notch may be provided in the guide 102, and the notch may be configured as a split roller. A configuration in which a pair of transport rollers described above may be provided. Although the guide 102 in the illustrated example is provided on the upper side and the lower side of the transport path, the present invention is not limited to this, and may not have any one of the upper side and the lower side. , Transport roller pair 104, 10
When the interval between the four is small, there may be a portion where the guide 102 is not provided.

The transport roller pair 104 is for carrying out the nipping and transporting of the photosensitive material Z, and has a drive roller 106 and a driven roller 114. Although not shown in FIGS. 3 and 4, a plurality of transport roller pairs 104 are provided in the downstream transport unit 100. Therefore,
Although only one transport roller pair 104 will be described, the other transport roller pair 104 may be similarly configured.

The drive roller 106 is a roller which is driven by contacting the back surface of the photosensitive material Z. As shown in FIGS. 3 and 4, two roller pieces 108, 108 and a rotating shaft 11 are provided.
0, and a drive source 112, and two roller pieces 108,
108 constitutes a first printing escape portion 120. That is, the two roller pieces 108, 108
₁ is arranged so as to be larger than the width x of the back print portion (hereinafter, referred to as the back print width x) (w ₁ > x).

The photosensitive material Z in the illustrated example is a photosensitive material Z.
The backprint of two lines, one line at a time, is recorded at left and right symmetrical positions with respect to the center position in the width direction of FIG. To the lower end of the lower row is the back print width x. Accordingly, when the photosensitive material Z is conveyed without being rotated (rotation angle is 0 degree) or is rotated by 180 degrees, the back print does not come into contact with the driving roller 106, and a clear back print is held. , Can be conveyed. In order to transport the photosensitive material A with high precision, a configuration in which a narrow roller piece is provided between the lines of the back print in which two lines are recorded may be adopted.

Note that the number of divisions of the transport roller 104, the division position, the interval between the roller pieces 108, 108 and the like are determined by the photosensitive material Z.
The number may be determined as appropriate according to the number of sorting columns, the number of printing lines for back printing, the printing position, the printing size, and the like, and is not particularly limited.

The outer peripheral surface of each roller piece 108, 108
Has a recess in the direction of the rotation axis.
Constitute the second print escape portion 122. Specifically,
Back print text on the outer peripheral surface of the
Width w larger than character size y _Two(W_Two> Y)
The groove-shaped recess formed as described above has one or more in the direction of the rotation axis.
Are formed. As a result, the photosensitive material Z is 90 degrees
When rotated and transported, parallel to transport roller 104
The back print lined up in
Without losing crisp back prints
Can be transported.

Incidentally, as shown in FIG.
If more than one line is recorded, the first line
If it passes through the print escape portion 122, the second and subsequent lines inevitably pass through the second print escape portion 122. Accordingly, one or a plurality of groove-shaped concave portions are formed on the outer peripheral surface of the roller piece 108 so as to separate the outer periphery having a length equal to the distance between two rows in the back print, and these are formed in the second print escape portion 122. And it is sufficient. As described above, the position, the number, the size, and the like of the second print escape portions (recesses) 122 in each of the roller pieces 108, 108 can be appropriately determined according to the print size, the number of print lines of the back print, the print position, and the like. Well, there is no particular limitation.

As described above, since the drive roller 106 has the first print runaway section 120 and the second print runaway section 122, when the drive roller 106 is rotated by 0 degrees or 180 degrees,
The back print is released from the first print escape section 120, and 9
In the case of rotation by 0 degrees, the back print can escape from the second print escape portion 122. Therefore, 0 degree, 90
No matter which angle of rotation is 180 degrees or 180 degrees, the back print can be conveyed without contacting the drive roller, and the back print can always be obtained clearly. . In the case where the distribution section 18 is configured to always rotate the photosensitive material Z by 90 degrees, the first print escape section 120 may be omitted.

The drive roller 106 according to the present invention may be basically configured as shown in the above-described example, but the present invention is not limited to this, and it is sufficient if the drive roller 106 has at least an outer peripheral surface having an uneven shape. For example, the outer peripheral surface may be formed in an embossed shape, a groove parallel to the rotating shaft 110 having a width irrelevant to the printing width may be formed on the outer peripheral surface, or a spiral groove may be formed. Good. Also in this case, since the photosensitive material Z can be sandwiched not by a surface but by a line or a point, it is not necessary to control the drive roller 106 by the control unit 116, and it is possible to reduce the adverse effect on the back print. . The material of the driving roller 106 is not particularly limited.
Is preferable because the impact given to the back surface is small.

The drive source 112 is provided so as to be connected to the end of the rotary shaft 110, and drives the drive roller 106 in accordance with an instruction from the control unit 116. Various known motors may be used. However, it is preferable to use a pulse motor because it can be easily controlled by the control unit 116. The drive source 112 may be directly connected to the rotating shaft 110, or may be connected to a gear or a pulley via a transmission means such as an endless belt. Such a drive source 112 may be provided for each transport roller pair 104, but is not limited to this. For example, as long as synchronization between the transport rollers 104 is ensured, for example, a plurality of transport roller pairs 104 104 is connected via a pulley and an endless belt, and one drive source 1
It is good also as a structure which drives by 12.

The control of the driving roller 106 is performed by the control unit 116. The control unit 116
This is for synchronizing the drive roller 106 so that the back print of the photosensitive material Z rotated by one degree passes through the second print escape portion 122 of the drive roller 106. More specifically, the control unit 116 is located near the downstream side of the distribution unit 18,
A sensor 118 for detecting the leading end of the photosensitive material Z may be provided, and the driving source 112 may be controlled based on a detection signal from the sensor 118.

The driving source 1 in such a control unit 116
Control 12 may be performed, for example, as follows. First,
When the tip of the photosensitive material Z reaches the sensor 118, the sensor 118 detects the photosensitive material Z and transmits a detection signal to the control unit 116. When the detection signal is transmitted, the control unit 116 drives the drive source 112 so that the drive roller 106 is at a predetermined set position, and then stops and waits. Thereafter, after a predetermined standby time has elapsed, the drive roller 106 is driven to a predetermined transport speed. Therefore, the setting position and the standby time of the drive roller 106 are
When the driving of the drive roller 106 is started and the second print escape portion (recess) 122 reaches the lowest point, the position and the time are set so that the character string of the back print passes through the conveying roller pair 114. By doing so, the character string of the back print rotated by 90 degrees can be transported without contacting the drive roller 106 at all.

The control method of the control unit 116 is not limited to this, and can be performed by various known methods. For example, after the leading end of the photosensitive material Z has passed the sensor 118, the character string of the back print is
The time required to pass through the sensor 4 is determined in advance, and the sensor 11
8, when the detection signal is transmitted, the amount of rotation required to synchronize the drive roller 106 is calculated based on the current orientation of the roller piece 108, and the drive roller 106 is temporarily operated according to the calculation result. The configuration may be such that the operation is stopped, the timing is adjusted, and the driving is started again.

Such a control is performed for each transport roller pair 104.
In the case where the drive source 112 is provided for each transport roller pair 104, the drive may be performed for each transport roller pair 104. However, as described above, a single drive source 112 can be used to transport a plurality of transport roller pairs 104.
Is driven, a plurality of transport roller pairs 10
4 are controlled at a time. In this case,
For example, when the back print of the photosensitive material Z conveyed while being rotated by 90 degrees passes through each drive roller 106, each drive is previously set so that each second print escape portion (recess) 122 is at the lowest point. The configuration may be such that the rollers 106 are set to be shifted by a predetermined angle.

The driven roller 108 is a roller to be driven while holding the photosensitive material Z in contact with the emulsion surface of the photosensitive material Z, and may be a known roller, and is not particularly limited.

In this embodiment, the back print is
The backprint of two lines, one line each, is recorded at predetermined symmetrical positions sandwiching the central position in the width direction of the photosensitive material Z and is separated from each other by a predetermined distance. However, the present invention is not limited to this. The number of print lines, the print position, the print size, and the like of the back print are not limited at all.
