As the subsequent processing, for example, the photographic paper S is loaded into another processing apparatus (not shown) by an operator, and development processing, cutting and sorting are performed, and a finished print is produced.

Returning to FIG. 1, the supply magazine 12, the exposure processing unit 14, the take-up magazine 16, the input unit 20 and the display unit 22 are controlled by the control unit 18.
The control unit 18 includes a CPU 102, a ROM 104, a RAM 106, and a hard disk drive (HDD: including a hard disk) 108 connected to each other via a bus 100.

  The CPU 102 executes various programs stored in the ROM 104, the HDD 108, etc., gives instructions to each component in the printing apparatus 10, and controls the operation of the printing apparatus 10.

  The ROM 104 stores a startup program and the like. The activation program is executed by the CPU 102 when the printing apparatus 10 is turned on. As a result, a program such as an operating system (OS) recorded in the HDD 108 is loaded into the RAM 106, and various processes and controls can be executed.

  In the RAM 106, a program for controlling the operation of the printing apparatus 10 is developed. The processing result of the program, temporary data for processing, display data (text data) for displaying a GUI or the like on the screen of the display unit 22. , Image data, etc.) and the like and used as a work area for the CPU 102. The display data developed on the RAM 106 is transmitted to the display unit 22, and the display unit 22 displays the display content (text, image, etc.) corresponding to the display data on the screen.

  The HDD 108 is a device for recording and reading programs, control data, text data, image data, and the like on the hard disk in accordance with instructions from the CPU 102.

  Further, such a control unit 18 is connected to a CD-ROM drive and a scanner (not shown). The CD-ROM drive reads programs and data recorded on the CD-ROM according to instructions from the CPU 102, and the scanner reads an image to be formed on the photographic paper S as read image data according to instructions from the CPU 102. Various data read by the CD-ROM drive or the scanner is stored in the HDD 108, for example.

  Further, a communication control unit (not shown) may be connected to the control unit 18. When the communication control unit is connected, the control unit 18 can be connected to a network such as the Internet, for example, and can accept and take in image data from other devices via the network in accordance with an instruction from the CPU 102. In addition, data can be transmitted / received to / from other apparatuses, or programs and data can be uploaded or downloaded.

Next, the processing of the photographic paper S in the initial state or error recovery operation of the printing apparatus 10 configured as described above will be described with reference to FIGS.
As shown in FIGS. 5 and 6, first, it is determined whether or not the printing apparatus 10 is in an initial state (step S1).

  In this embodiment, the “initial state” means a state in which the initialized printing apparatus 10 is activated and no processing is performed, for example, due to an instantaneous power failure or power OFF / ON based on the operator's will. Say. Specifically, this means a state in which processing results and temporary data of programs other than the startup program are not held in the RAM 106. When the printing apparatus 10 is in an initial state, errors other than a conveyance error are canceled.

  In addition to turning the power off and on, the printing apparatus 10 is also in an initial state by opening and closing the printer door 14a.

  Furthermore, “startup” means that the control program is expanded in the RAM 106 and the preparation (initial operation) for the printing apparatus 10 to perform some processing is completed.

  When the printing apparatus 10 is in the initial state, the CPU 102 determines whether or not the printing apparatus 10 is in a conveyance error state (step S3).

  When the CPU 102 determines that the conveyance error state is present, a predetermined text or image is displayed on the display unit 22 based on an instruction from the CPU 102 to notify the operator that the printing apparatus 10 is in the conveyance error state (step S5). Subsequently, a transport error canceling operation is performed by the operator (step S7).

  The “transport error” refers to a state in which the photographic paper S cannot be transported in the exposure processing unit 14 such as a paper jam of the photographic paper S in the exposure processing unit 14.

  In the transport error release operation in step S7, the printer door 14a is opened, and the components related to the transport error in the exposure processing unit 14 are adjusted so that the printing paper S can be transported. At this time, the photographic paper S is taken out from the exposure processing unit 14 so that any sensor on the conveyance path does not detect the photographic paper S. Thereafter, the printer door 14a is closed, the printing apparatus 10 is in an initial state, and the process returns to step S3.

  In step S1, if the CPU 102 detects an abnormality when the printing apparatus 10 is not in the initial state and is executing some process (step S9), the process being executed is stopped, and the detected abnormality is conveyed by the CPU 102. It is determined whether or not an error has occurred (step S11). If the detected abnormality is an error other than a conveyance error, text or an image corresponding to the display unit 22 is displayed based on an instruction from the CPU 102 to notify the operator that an error has occurred (step S13). Thereafter, the error recovery operation is started, and the process proceeds to error processing based on an instruction given by the operator from the input unit 20 (step S15).

  On the other hand, if the detected abnormality is a transport error in step S11, the process proceeds to step S5.

  In the error processing of step S15, for example, the processing result and temporary data of the program held in the RAM 106 are erased, and the program developed in the RAM 106 is set to be executed again. Subsequently, the CPU 102 determines whether or not the photographic paper S is stopped on the transport path in the exposure processing unit 14 (whether the photographic paper S is loaded in the exposure processing unit 14) (step S17).

  If the CPU 102 determines in step S3 that the conveyance error state is not present, the process proceeds to step S17.

  In step S17, as shown in FIGS. 7 to 13, when any sensor on the transport path detects the photographic paper S, the CPU 102 determines that the photographic paper S is stopped on the transport path, and continues. Then, it is determined whether or not the photographic paper S on the transport path has reached the take-up magazine 16 (step S19).

  As shown in FIGS. 7 to 10, when the paper sensor 84 detects the photographic paper S, the CPU 102 determines that the photographic paper S has reached the take-up magazine 16, and then conveys the photographic paper S and winds it up. It is determined whether or not it is necessary to take up the magazine 16 (step S21).

  As shown in FIGS. 7 to 9, when the paper sensor 84 and a sensor other than the paper sensor 84 detect the photographic paper S, the CPU 102 determines that the photographic paper S needs to be wound around the take-up magazine 16, and continues. Then, it is determined whether or not the photographic paper S is in a cuttable position (step S23).

  As shown in FIGS. 7 and 8, when the paper end sensor 26 detects the photographic paper S, the CPU 102 determines that the photographic paper S is in a severable position and cuts the photographic paper S into the paper cutter 30. An instruction is given and the photographic paper S is cut (step S25). Subsequently, the roller in the supply unit 24 is driven based on an instruction from the CPU 102, and the photographic paper S on the supply unit 24 side of the cut photographic paper S is rewound onto the supply magazine 12 (step S27).

  When the continuous printing paper S from the supply unit 24 to the take-up magazine 16 is cut by the cutting operation in step S25, the printing paper S on the supply unit 24 side is rewound onto the supply magazine 12 as shown in FIG. Thus, the photographic paper S is not detected by the paper end sensor 26 (step S29).

  Subsequently, each roller on the conveyance path is driven based on an instruction from the CPU 102, the photographic paper S continuous with the winding magazine 16 is conveyed to the downstream side of the conveyance path, and the photographic paper S is taken up by the winding magazine 16. (Step S31).

  When the conveyance of the photographic paper S and the winding to the winding magazine 16 proceed and only the paper sensor 84 detects the photographic paper S as shown in FIG. 10, the winding of the photographic paper S to the winding magazine 16 is performed. Removal is complete. At this time, based on an instruction from the CPU 102, each roller on the conveyance path stops conveyance of the photographic paper S, a predetermined text or image is displayed on the display unit 22, and the take-up magazine 16 needs to be replaced. Inform the operator (step S33). When the take-up magazine 16 is replaced by the operator (step S35), the processing of the photographic paper S in the initial state or error recovery operation is completed.

  On the other hand, in step S29, if the photographic paper S whose rear end is missing from the supply unit 24 is cut due to the cutting of the supply magazine 12 in the cutting operation of step S25, as shown in FIG. However, the photographic paper S on the supply unit 24 side cannot be rewound into the supply magazine 12 and the paper end sensor 26 continues to detect the photographic paper S. In this case, a predetermined text or image is displayed on the display unit 22 based on an instruction from the CPU 102, and the operator is informed that the photographic paper S remains in the vicinity of the supply unit 24 (step S37).

  Subsequently, the supply magazine 12 is removed from the exposure processing unit 14 by the operator, and the photographic paper S remaining on the transport path and in the vicinity of the supply unit 24 is taken out (step S39). Thereafter, the supply magazine 12 is attached again to the exposure processing unit 14 by the operator, and the process proceeds to step S31.

  In step S23, as shown in FIG. 9, when the trailing end of the photographic paper S is at least downstream of the paper end sensor 26 and the paper end sensor 26 does not detect the photographic paper S, the CPU 102 It is determined that S is not at the position where cutting is possible, and the process proceeds to step S31.

  If only the paper sensor 84 detects the photographic paper S in step S21, the CPU 102 determines that the winding of the photographic paper S to the take-up magazine 16 has been completed (see FIG. 10), and step S33. Proceed to

  In step S19, as shown in FIGS. 11 to 13, when the leading edge of the photographic paper S is positioned on the transport path and the paper sensor 84 does not detect the photographic paper S, the CPU 102 takes up the photographic paper S in the take-up magazine. It is determined that 16 has not been reached. If the photographic paper S does not reach the take-up magazine 16, the position of the leading end of the photographic paper S cannot be accurately grasped in the exposure processing unit 14, and the photographic paper S is taken up on the take-up magazine 16. I can't.

  In this case, the CPU 102 detects the photographic paper S by the paper sensor 50 and does not detect the photographic paper S by the paper sensor 52 (see FIG. 12), in other words, so that the leading edge of the photographic paper S is positioned at the dancer section 34. Based on the instruction, each roller in the exposure processing unit 14 conveys the photographic paper S (step S41). Subsequently, a predetermined text or image is displayed on the display unit 22 based on an instruction from the CPU 102 and prompts the operator to take out the photographic paper S (step S43).

  Subsequently, the operator removes the supply magazine 12 from the exposure processing unit 14 and cuts the photographic paper S in the supply unit 24. Then, the printer door 14a is opened, and the photographic paper S is taken out from the dancer section 34 (step S45). Thereafter, the supply magazine 12 is attached again to the exposure processing unit 14, the printer door 14a is closed, the printing apparatus 10 is in an initial state, and the process returns to step S3.

  If no sensor on the transport path detects the photographic paper S in step S17, the processing of the photographic paper S in the initial state or the error recovery operation ends.

  In steps S5, S13, S33, S37, and S43, a voice or the like may be emitted from a speaker (not shown) to notify the operator.

  In the initial state or in the error recovery operation, it can be set in advance whether or not the processing after step S17 is performed, and this setting information is recorded in the HDD.

  According to such a printing apparatus 10, in an error recovery operation other than the initial state or the conveyance error, the photographic paper S on the conveyance path in the exposure processing unit 14 is cut if necessary, and the take-up magazine 16 is automatically cut. Therefore, the operator's operation and work are not required, and the burden on the operator can be reduced.

  Further, by automatically processing the photographic paper S in the initial state or error recovery operation, it is possible to prevent an operator's operation mistake or work mistake.

  Further, the printing apparatus 10 is initialized in a state where the leading edge of the photographic paper S does not reach the take-up magazine 16 or an abnormality other than a conveyance error occurs, and the photographic paper S is manually conveyed in the exposure processing unit 14. Even when it is necessary to take out from the path, the operator simply transports the photographic paper S on the transport path because the leading edge of the photographic paper S is transported so as to be arranged in the dancer section 34 in the initial state or error recovery operation. Can be taken out.

  Furthermore, since a predetermined text or image is displayed on the display unit 22 in the case of a transport error, the operator can promptly respond to the transport error even when the photographic paper S cannot be processed automatically. It can be carried out.

  The photosensitive material used in the present invention is not limited to photographic paper, and may be a cloth or a plastic film.
