By being input, the roller driving units 116, 120, 133, 140, 170, 178, 186, 195, the shutter driving unit 117, the lens driving unit 118 and the cutter driving unit 153 of the first printing processing unit 10, the second Image data output unit 213, pad / roller driving unit 215, roller driving units 233, 242, 251, 253, 263, 270, loop guide driving unit 241, cutter driving unit 245, guide driving unit 248, and Guide / roller drive unit 252, roller drive units 315 and 337 of development processing unit 30, and temperature increase 351 The drive control respectively.

  The printing and developing apparatus configured as described above operates as follows. That is, when the film image is printed, and the composite image of the pattern image and the character image is not required, the first printing processing unit 10 is selected by the printing processing unit selection key SK. When various conditions are set and the start switch SW is turned on, the film image projection unit 11 winds the negative film F frame by frame, and the film images are sequentially projected onto the printing unit 12. On the other hand, the photographic paper is sequentially drawn out from the magazine MG1 (or MG2) on the magazine placement unit 13, cut into a predetermined length by the cutter unit 15, and conveyed onto the printing unit 12 in order. Drawing of the photographic paper from the magazine MG1 (or MG2) is performed in synchronization with the winding of the negative film F of the film image projection unit 11.

  The photographic paper printed by the printing unit 12 is conveyed to the downstream side by the conveyance belt 123, and conveyed to the development processing unit 30 side by the horizontal conveyance unit 161, the oblique conveyance unit 162, the vertical conveyance unit 163, and the discharge unit 164.

  The photographic paper transported to the development processing unit 30 side is fed to the development processing start position SP by the feeding unit 31 and is carried into the processing tank 33 for development processing. The photographic paper for which the development process has been completed is conveyed into the drying processing chamber 35 and dried, and the photographic paper for which the drying process has been completed is discharged to the photographic paper discharge unit 40.

  Next, the operation when the second printing processing unit 20 is selected by the printing processing unit selection key SK will be described with reference to the flowchart of FIG. 12 and the operation diagrams of FIGS. The case where the second printing processing unit 20 is selected is a case where a composite image of a pattern image and a character image is required. In this case, as a previous step, a pattern image such as a film is read in advance by an imaging device by an external device such as a personal computer, while character data is input from a keyboard or the like and synthesized with the pattern image, and predetermined image processing is performed on the image data. Is given.

  When the previous operation is completed and various conditions are set and the start switch SW is turned on, it is first determined whether or not the leading edge cutting process of the photographic paper has been designated (step S1). The leading edge cutting process cuts the leading edge portion by a certain length (for example, about 100 mm) perpendicular to the longitudinal direction when the leading edge of the photographic paper in the magazine is not cut perpendicular to the longitudinal direction. Refers to processing.

  When the leading edge cutting process is not designated (NO in step S1), the photographic paper drawn from the magazine MG3 is loaded onto the first transport unit 23 (step S2). At this time, as shown in FIG. 13, the driven roller 236b of the second conveying roller 236 is separated from the driving roller 236a, and the loop guide 240 of the loop forming portion 235 is switched to the first position. . In this state, the photographic paper P is pulled out from the magazine MG3 until the first transport roller 234 rotates and the leading edge of the photographic paper P reaches the photographic paper sensor S2.

  The pressure pad 216 is moved to a position away from the display surface 214 of the image display unit 211, and the guide plate 244 of the stock unit 238 and the driven roller 250b of the third transport roller 250 are transported from the upstream side. The photographic paper P has been moved to a position for guiding it into the photographic paper storage box 243.

  When the leading edge of the photographic paper P reaches the photographic paper sensor S2, the loop forming unit 235 starts to form a loop of the photographic paper P, and the photographic paper P is stored in the loop forming unit 235 (step S3). That is, when the leading edge of the photographic paper P reaches the photographic paper sensor S2, as shown in FIG. 14, the driven roller 236b of the second conveying roller 236 moves toward the driving roller 236a, and the photographic paper P is moved to the driving roller 236a. The loop guide 240 is moved to the second position while being sandwiched by the driven roller 236b and fixed at that position. In this state, the photographic paper P is continuously pulled out from the magazine MG3 by the first transport roller 234. As a result, the loop forming section 235 forms a loop of the photographic paper P. This operation is continued until the loop sensor S1 detects the top of the photographic paper loop.

  In this embodiment, the loop sensor S1 has a length Amm between the position of the photographic paper sensor S2 and the center position of the image display unit 211, and the length of the photographic paper P that forms a loop in the loop forming unit 235. When the value obtained by adding the length Bmm necessary for the baking process corresponding to the baking size is Nmm, the value is obtained by subtracting 50 mm from this Nmm. Here, the reason why 50 mm is subtracted is to shorten the length of the remaining photographic paper P that is disposed of when the magazine MG3 is replaced after the photographic paper P is used.

  Next, the photographic paper P corresponding to the length necessary for the printing process is sent out from the loop forming unit 235 (step S4). That is, as shown in FIG. 15, when the driving roller 236a of the second transport roller 236 is rotationally driven, the length from the center position of the image display unit 211 to the leading edge of the photographic paper P is necessary for the printing process. The printing paper P is sent out from the loop forming unit 235 through the image display unit 211 so as to have a length. The fed photographic paper P has the guide plate 244 and the driven roller 250b of the third transport roller 250 at the positions shown in FIG. 6B, and therefore is placed in the photographic paper storage box 243 along the guide plate 244. It is guided and stored in the photographic paper storage box 243 in a loop shape.

  In step S4, the first conveying roller 234 is also rotated simultaneously with the rotation of the second conveying roller 236, and the photographic paper P is drawn out from the magazine MG3. The photographic paper P in the loop forming unit 235 is substantially omitted. It is designed to maintain a certain length.

  In this way, since the photographic paper P is fed from the loop forming unit 235 to the stock unit 238, a substantially constant and stable load is applied to the photographic paper P, and the exact length of the photographic paper P is increased. Minutes can be sent out.

  Next, a printing process is performed on the photographic paper P (step S5). That is, as shown in FIG. 16, the pressure pad 216 is pressed against the display surface 214 of the image display unit 211, while the driving roller 236a of the second transport roller 236 rotates intermittently in the reverse direction to store the photographic paper. The photographic paper P in the box 243 is intermittently reversely fed in a state of being in close contact with the display surface 214 of the image display unit 211. At this time, the image display unit 211 is driven, and an image is displayed on the display surface 214 one or several lines at a time in synchronization with the feeding operation of the photographic paper P, whereby the printing process for the photographic paper P is performed.

  Note that the photographic paper P in the vicinity of the loop forming unit 235 is returned into the loop forming unit 235 by the reverse feeding of the photographic paper P. When the printing process is finished, the pressure pad 216 moves away from the display surface 214 of the image display unit 211.

  Since the printing paper P is fed back from the stock unit 238 and printed in this way, an unstable load is not applied to the printing paper P. Therefore, the printing paper P is fed back at a high-precision pitch. Is possible. The second conveyance roller 236 and the roller driving unit 242 that drives the second conveyance roller 236 and the roller driving unit 251 that drives the third conveyance roller 2250 and the third conveyance roller 250 are a loop forming unit. The photographic paper P stored in 235 passes through the image display unit 211 and is conveyed downstream, and the photographic paper P conveyed downstream during the image printing process in the image display unit 211 is sent back to the upstream side. Conveyance driving means 255 is configured.

  Next, the printing paper P that has been printed is sent out to the cutter unit 239 (step S6). At this time, as shown in FIG. 17, the guide plate 244 and the driven roller 250b of the third conveying roller 250 which have been in the position shown in FIG. 6B until now move to the positions shown in FIG. 7B. . That is, as a result of the guide plate 244 moving below the vertical conveyance unit 232 on the downstream side of the third conveyance roller 250, the photographic paper P conveyed from the upstream side is not conveyed to the photographic paper storage box 243 and is conveyed vertically. The unit 232 is in a state of being conveyed to the cutter unit 239 side. The driven roller 250b is close to the drive roller 250a, but a gap is still formed between the two and the photographic paper P can pass freely through the gap.

  In this state, the photographic paper P for which the printing process has been completed is conveyed by the second conveying roller 236 to a position where the leading end reaches the photographic paper sensor S3 immediately before the cutter unit 239. At the same time, the photographic paper P is pulled out from the magazine MG3 by the first transport roller 234 and the photographic paper P in the loop forming portion 235 is maintained at a substantially constant length.

  When the leading edge of the photographic paper P reaches the photographic paper sensor S3, the driven roller 236b of the second transport roller 236 is separated from the driving roller 236a as shown in FIG. Further, the guide plate 244 and the driven roller 250b of the third transport roller 250, which have been in the position shown in FIG. 7B until now, move to the position shown in FIG. 8B, and the driven roller 250b moves the photographic paper P. , The driving roller 250a is rotationally driven, and the length of the printing paper P printed on the basis of the position of the printing paper sensor S3 is conveyed to the cutter unit 239 side. Thereafter, the cutting process of the photographic paper P is performed (step S7). When the length of the printing paper P that has been printed is transported to the cutter unit 239 side, the fourth transport roller 249 on the downstream side of the cutter unit 239 is also driven to rotate, and the cut printing paper P is moved to the second side. Is fed into the transport section 26.

  Next, it is determined whether or not it is necessary to continue the baking process (that is, whether or not repeat baking is performed) (step S8). When it is necessary to continue the printing process (YES in step S8), whether or not the printing process has a white edge portion of the photographic paper (that is, whether or not the printing process has a white edge around the printed image). The designated printing type is determined (step S9). Then, at the time of the printing process without the white edge portion (when so-called borderless printing in which the edge portion of the image is printed on a wide area corresponding to a minute dimension) (NO at step S9), the front end portion of the photographic paper P is cut. Is performed (step S10). That is, as shown in FIG. 19, the photographic paper P after being cut in step S7 is conveyed to the cutter unit 239 side by a predetermined dimension (for example, about 3 mm) by the third conveying roller 250, and the leading end portion is cut. . As a result, the edge portion of the image that has been printed onto the eye that is wider by the minute dimension (the portion on the leading end side of the printing paper P that is to be printed next) is deleted. At this time, the guide plate 247 located below the cutter unit 239 moves to the second position and guides the chips into the chip storage box 246. Thereafter, the guide plate 247 moves to the original first position.

  Next, it is determined whether or not the length of the photographic paper P to be continuously printed is equal to or less than the distance (for example, 152 mm) between the center of the image display unit 211 and the cutter unit 239 (step S11). At this time, as shown in FIG. 20, the guide plate 244 and the driven roller 250b which have been in the position of FIG. 8B until now move to the position of FIG. 9B, and the driven roller 250b is moved from the drive roller 250a. The driven roller 236b moves to the driving roller 236a side, and the photographic printing paper P is sandwiched between the driving roller 236a and the driven roller 236b. At this time, the first transport roller 234 is simultaneously rotated to form a loop of the photographic paper P in the loop forming unit 235. When the loop sensor S1 detects a loop, the first transport roller 234 stops.

  When the length of the photographic paper P to be continuously printed is equal to or shorter than the above length (YES in step S11), the center of the image display unit 211 and the photographic paper are detected by the second transport roller 236 as shown in FIG. Reverse feed is performed until the length of the tip of P reaches the length required for the baking process. In addition, when the length required for the printing process is the same as the distance between the center of the image display unit 211 and the cutter unit 239, it is not necessary to perform reverse feeding. Thereafter, the pressure pad 216 is pressed against the display surface 214 of the image display unit 211, and the photographic paper P is intermittently fed back by the second transport roller 236, and the image display unit 211 performs the printing process in the same manner as described above. (Step S12). Then, it returns to step S6 and the said operation | movement is repeated.

  Note that if the distance between the center of the display surface 214 of the image display unit 211 and the cutter unit 239 is set in correspondence with the printing size (printing paper size) having a high printing frequency, the second and subsequent frames less than the printing size are set. During the printing process, the length required for the printing process of the photographic paper P can be directly fed back from the cutter unit 239 without being stocked in the stock unit 238, which increases the processing speed and increases the printing efficiency. It becomes possible.

  Further, when the length of the photographic paper P required for the subsequent printing process exceeds the above length (NO in step S11), the leading edge of the photographic paper P is positioned at the upstream side closest to the third conveying roller 250. The printing paper P is fed back by the second transport roller 236 in a state where the pressure pad 216 is separated from the display surface 214 of the image display unit 211 until it reaches. Then, after the guide plate 244 and the driven roller 250b that were in the position of FIG. 9B are moved to the position shown in FIG. 6B, the photographic paper P is necessary for the printing process by the second transport roller 236. The paper is sent out from the loop forming portion 235 until it reaches the length, and is stored in the photographic paper storage box 243.

  As shown in FIG. 22, the photographic paper P in the photographic paper storage box 243 is intermittently reversed by the second transport roller 236 in a state where the pressure pad 216 is pressed against the display surface 214 of the image display unit 211. The image display unit 211 performs the printing process in the same manner as described above (step S13). Then, it returns to step S6 and the said operation | movement is repeated. Note that, in the printing process with a white edge portion (YES in step S9), the processes after step S11 are executed.

  When it is not necessary to continue the baking process after the cut process in step S7 (NO in step S8), it is further determined whether or not the printing process has a white edge (step S14). Then, at the time of printing without white edges (NO in step S14), the leading edge of the photographic paper P is cut in the same manner as in step S10 (step S15). Further, at the time of printing processing with a white edge (YES in step S14), the photographic paper P is rewound into the magazine MG3 (step S16). Note that the photographic paper P for which the printing process has been completed is transported to the development processing unit 30 by the second transport unit 26, and the same development processing as in the case of the first printing processing unit 10 is performed.

  When the leading edge cutting process of the photographic paper P is designated (YES in step S1), the photographic paper drawn from the magazine MG3 is loaded onto the first transport unit 23 in the same manner as in step S2 (step S17). Subsequently, a loop of the photographic paper P is formed by the loop forming unit 235 in the same manner as in step S3 (step S18). Then, as in step S6, the photographic paper P is conveyed to the cutter unit 239 (step S19), and the leading end is cut at right angles to the longitudinal direction by a certain length (step S20). Then, it progresses to step 11 and the baking process similar to the above is performed.

  In the printing and developing apparatus of the present invention, as described above, the photographic paper transport unit is disposed on the upstream side of the image display unit, and the loop forming unit stores the photographic paper drawn out from the magazine in a loop shape. And the photographic paper stored in the loop forming unit are transported downstream from the loop forming unit through the image display unit by a length necessary for image printing, and image display is performed. Transport driving means for reversely transporting the photographic paper transported downstream to the upstream side during the image printing process on the photographic paper in the printing section.

  For this reason, since a substantially constant and stable load is applied to the photographic paper in the loop forming unit, the photographic paper having an accurate length dimension can be conveyed downstream from the loop forming unit through the image display unit. At the same time, since an unstable load is not applied to the photographic paper conveyed to the downstream side, the photographic paper conveyed to the downstream side during the printing process in the image display unit can be fed back to the upstream side with high accuracy. Thus, a combined image of the pattern image and the character image can be efficiently printed.

  In the above-described embodiment, the image display unit 211 of the image transfer unit 21 constituting the second printing processing unit 20 is configured by FOCRT so as to be in close contact printing, thereby obtaining an image with high definition. However, the image display unit 211 can also be configured using a PLZT element instead of the FOCRT. When this PLZT element is used, the drive circuit unit 212 and the image data output unit 213 may have a known configuration corresponding to PLZT. The PLZT element is a shutter array made of a transparent ferroelectric ceramic material obtained by adding lanthanum to lead zirconate titanate and utilizing the electro-optic effect of the material. Furthermore, the image display unit 211 can be configured using a CRT (Cathode-Ray-Tube) instead of the FOCRT. In this case, the image is not displayed every one to several lines as in FOCRT, but the entire image is displayed simultaneously. In short, as the image display unit 211, various types can be adopted as long as the image data is converted into an optical signal and output onto the photographic paper.

  In the above embodiment, the length of the photographic paper P conveyed from the loop forming unit 235 to the stock unit 238 during the printing process of the photographic paper in the second printing processing unit 20 is the length necessary for the printing process. However, it is also possible to carry it a little longer than that. Further, various modifications can be made to the detailed configuration and operation of the printing and developing apparatus in the above embodiment.
