The elevating cam 83 has a cam nose whose distance from the cam rotation shaft 82 is divided into at least two stages, and these cam noses are connected by a gentle curve.

  Here, referring to FIGS. 6 to 8, in accordance with the operation of the above-described sub tank lifting mechanism 80, the replenishing tanks 712 to 716 are replenished with the processing liquid from the replenishing tanks 712 to 716, and the replenishment is performed. The replenishing valve unit 79 that can be opened and closed between the closed and closed state will be described.

  6 to 8 are cross-sectional views showing a detailed configuration of the replenishing valve unit 79. FIG. 6 shows that the check liquid 79a of the replenishing valve unit 79 of the processing liquid replenishing tanks 712 to 715 is closed and the processing liquid is processed. FIG. 7 shows a state where the check valve 79a is opened and the processing liquid is supplied from the processing liquid replenishing tanks 712 to 715 to the processing liquid sub tanks 732 to 735. FIG. 8 shows a state in which the check valve 79a is closed and the processing liquid is supplied from the processing liquid sub tanks 732 to 735 to the developing tank. The replenishing valve portion 79 (cleaning liquid replenishing valve portion 79B) of the cleaning liquid replenishing tank 716 has the same configuration as the processing liquid replenishing valve portion 79A of the processing liquid replenishing tanks 712 to 715. Detailed drawings and description will be omitted.

  Referring to FIGS. 6 to 8, the processing liquid replenishment valve section 79A of the processing liquid replenishing tanks 712 to 715 corresponds to the lower part of the processing liquid replenishing tanks 712 to 715, that is, the processing liquid replenishing tanks 712 to 715. A liquid discharge port 79b that is provided for each of the flow paths between the processing liquid sub-tanks 732 to 735 and opens downward in the processing liquid replenishment tanks 712 to 715, and above the liquid discharge port 79b. And a valve seat surface 79c facing upward. In addition, the replenishing valve portion 79 is in contact with the valve seat surface 79c from above and stops replenishing the processing liquid from the processing liquid replenishing tanks 712 to 715, and retreats upward from the valve seat surface 79c. A check valve 79a whose posture can be changed between the processing liquid replenishing tanks 712 to 715 and an open state in which the processing liquid is replenished is provided. The check valve 79a is operated by a check valve urging means 79d. The valve seat surface 79c is biased to a closed state.

  Then, as shown in FIG. 7, the check valve 79a is pushed by valve opening pins 732b to 735b (to be described later) of the sub tank portion 73 at the liquid discharge port 79b and retreats into the replenishing tanks 712 to 715. The discharge port 79b is opened, and the processing liquid or the like is supplied to the processing liquid sub tanks 732 to 735. As shown in FIG. 7, when the check valve 79a is open and the liquid level of the processing liquid to be replenished reaches the liquid discharge port 79b of the check valve 79a, the processing liquid replenishing tanks 712 to 715 are processed. The exchange between the liquid and external air is stopped, and the replenishment of the processing liquid to the processing liquid sub tanks 732 to 735 is stopped.

  In this manner, the sub tank lifting mechanism 80 brings the processing liquid replenishing tanks 712 to 715 close to the processing liquid sub tanks 732 to 735 to replenish the tops of the valve opening pins 732 b to 735 b of the processing liquid sub tanks 732 to 735. By interfering with the lower surface of the check valve 79a of the valve portion 79, a replenishment state (FIG. 7) is set for opening the check valve 79a against the urging force of the check valve urging means 79d. Further, the replenishing tanks for treatment liquid 712 to 716 and the sub tanks for treating liquid 732 to 736 are separated from each other, and the tops of the valve opening pins 732 b to 735 b are retracted downward from the lower surface of the check valve 79 a of the replenishing valve part 79. Thus, the refill stop state (FIGS. 6 and 8) is set to close the check valve 79a. The same applies to the cleaning liquid replenishment tank 716, the cleaning liquid sub tank 736, and the cleaning liquid replenishing valve section 79B.

  Here, referring again to FIG. 3 and FIG. 4, the flow path of each processing liquid and the flow path opening / closing mechanisms 75 and 76 will be described.

  Each of the processing liquid sub tanks 732 to 735 is provided with inlets 732a to 735a (FIG. 4) for introducing the cleaning liquid at the upper part of the side wall, and the cleaning liquid supply hose 77 is connected to the inlets 732a to 735a.

  In addition, the bottom surfaces of the processing liquid sub tanks 732 to 735 are connected to a liquid supply hose 74 for each processing liquid through a liquid discharge port.

  The liquid supply hose 74 is a flexible hose (for example, a vinyl chloride hose) for supplying liquid, and is crushed by applying an external force from the side surface to close the internal flow path. The liquid supply hoses 74 for the respective processing liquids are joined at the downstream portion thereof to form one combined liquid supply hose 74a, and a liquid heating heater for heating the respective processing liquids to the outer peripheral portion of the combined liquid supply hose 74a. 78 is provided. The combined liquid supply hose 74a is connected to a liquid supply port 424 (FIG. 5) of the developing tank 42, whereby the processing liquid heated to a predetermined appropriate temperature is introduced into the developing tank 42.

  A first flow path opening / closing mechanism 75 that opens and closes the liquid flow path of each hose 74 is provided on the upstream side of the junction of the liquid supply hose 74. The first flow path opening / closing mechanism 75 is provided in a flow path for supplying a processing liquid from the processing liquid sub tanks 732 to 735 to the developing tank 42, and processing is performed from the processing liquid sub tanks 732 to 735 to the developing tank 42. It is provided so that it can be opened and closed between an open state in which the liquid is supplied and a closed state in which the supply is stopped. Then, by switching between a fully closed state in which the flow paths by all the liquid supply hoses 74 are closed and an individual open state in which the flow paths by the respective liquid supply hoses 74 are individually opened, the sub tanks 732 to 735 for each processing liquid are used. Each processing solution that naturally falls toward the developing tank 42 is circulated and stopped.

  More specifically, as shown in FIGS. 6 to 8, the first flow path opening / closing mechanism 75 has crushing means 756 that crush each liquid supply hose 74 to stop the flow of the processing liquid. The crushing means 756 includes a roller pressing cam 751 that rotates and a crushing roller that rolls on the outer peripheral surface of the roller pressing cam 751 and crushes the liquid supply hose 74 according to the rotation angle of the cam 751. 752, a roller urging means (not shown) for applying a urging force for maintaining the crushing roller in the retracted state from each liquid supply hose 74, a cam center shaft 753 that is the rotation center of all the cams 751, and an output shaft. A drive unit 754 (FIG. 4) formed of a stepping motor or the like directly connected to the cam center shaft 753 is disposed opposite to the crushing roller 752 with the liquid supply hose 74 interposed therebetween, and the hose 74 is sandwiched between the roller 752. Crush And a pressing plate 755 that.

  The roller pressing cam 751 can take a pressing posture in which a crushing roller is pressed against the side wall of each liquid supply hose 74 against a biasing force of a roller biasing means (not shown). It is like that.

  Specifically, the roller pressing cam 751 is formed as a substantially disk body, and a part of the outer peripheral surface is recessed inward in the radial direction to form a roller retracting portion 751a. The roller retracting portion 751a is formed in different phases depending on each roller pressing cam 751. Accordingly, the crushing rollers 752 corresponding to the respective cams 751 are sequentially accommodated in the corresponding roller retracting portions 751a while the cam central shaft 753 makes one rotation, whereby the flow path by the liquid supply hose 74 is sequentially opened. At the same time, all the crushing rollers 752 are brought into contact with the outer peripheral surface of the cam 751 removed from the roller retracting portion 751a, thereby closing the flow paths by all (four) liquid supply hoses 74. Become.

  When the roller pressing cam 751 rotates, the crushing roller 752 swings in and out of the roller retracting portion 751a, and thereby swings in a direction in which it contacts and separates from the liquid supply hose 74, thereby crushing the liquid supply hose 74. Thus, the position can be switched between a position where the flow path is closed and a position where the liquid supply hose 74 is released to release the flow path.

  Further, the crushing means 756 is configured to drive each roller pressing cam 751 with one driving unit 754 (FIG. 4) with respect to at least two of the liquid supply channels. .

  As shown in FIGS. 3 and 4, the cleaning liquid sub tank 736 among the sub tanks 732 to 736 is set at a position where the bottom surface is higher than the bottom surfaces of the processing liquid sub tanks 732 to 735. By thus supporting the cleaning liquid sub tank 736 at a high position, the cleaning liquid can be supplied from the cleaning liquid sub tank 736 toward the processing liquid sub tanks 732 to 735 by natural fall.

  The cleaning liquid sub tank 736 opens the cleaning liquid replenishing valve portion 79B of the cleaning liquid replenishing tank 716 on the bottom surface of the storage section for storing the processing liquid, similarly to the processing liquid sub tanks 732 to 735 described above. A pin 736b is provided. When the cleaning liquid replenishing valve 79B is opened by the valve opening pin 736b, the processing liquid in the cleaning liquid replenishing tank 716 is exchanged with the external air, and the cleaning liquid is supplied from the liquid discharge port of the cleaning liquid replenishing tank 716. Is discharged to the cleaning liquid sub-tank 736, and the discharge of the cleaning liquid from the cleaning liquid replenishment tank 716 is stopped when the level of the cleaning liquid reaches the liquid discharge port of the cleaning liquid replenishment tank 716. That is, when the liquid level reaches the liquid discharge port of the cleaning liquid replenishment tank 716, the supply of air from the liquid discharge port is cut off, and the exchange of the processing liquid in the cleaning liquid replenishment tank 716 with external air is stopped, The cleaning liquid is measured by utilizing the negative pressure acting in the cleaning liquid replenishment tank 716, and the height of the valve opening pin 736b is set in consideration of the amount of the cleaning liquid to be replenished to the cleaning liquid sub tank 736. ing.

  The cleaning liquid sub-tank 736 is connected to a cleaning liquid supply hose 77 for supplying the cleaning liquid to the processing liquid sub-tanks 732 to 735 through a discharge port provided on the bottom surface in accordance with the number of the developing processing liquids. As the cleaning liquid supply hose 77, a flexible hose (for example, a vinyl chloride hose) is used, which is crushed by applying an external force from the side surface to close the internal flow path. In the middle of the cleaning liquid supply hose 77, a second flow path opening / closing mechanism 76 for opening and closing the cleaning liquid flow path by the cleaning liquid supply hose 77 is provided. The cleaning liquid that naturally falls from the sub tank 736 toward the processing liquid sub tanks 732 to 735 is circulated and stopped.

  Here, the second flow path opening / closing mechanism 76 (corresponding to the cleaning liquid supply flow path opening / closing mechanism) is provided in the cleaning liquid supply flow path for supplying the cleaning liquid from the cleaning liquid sub tank 736 to each of the processing liquid sub tanks 732 to 735. The cleaning liquid supply hose 77 can be opened and closed between an open state in which the processing liquid is supplied from the cleaning liquid sub tank 736 to each of the processing liquid sub tanks 732 to 735 and a closed state in which the supply is stopped. Thus, crushing means 764 is provided that enables the flow of the processing liquid to be stopped. The crushing means 764 crushes and closes the flow path by a cam mechanism that applies pressure to the cleaning liquid supply hose 77 from the side surface, and opens the flow path by elastic recovery of the cleaning liquid supply hose 77 by removing the pressure. Adopting a mechanism to The hose crushing cam 763 of this cam mechanism is rotated to crush all (four) cleaning liquid supply hoses 77 corresponding to the processing liquid sub tanks 732 to 735 together with the pressing plate 765, and all the cleaning liquids. It is configured to be switchable to a posture separating from the supply hose 77, thereby opening and closing the flow path by the cleaning liquid supply hose 77.

  On the downstream side of the second flow path opening / closing mechanism 76, the cleaning liquid supply hose 77 is connected to the processing liquid sub tanks 732 to 735, respectively. After the development processing of one film 2 is completed, when the flow path by the cleaning liquid supply hose 77 is opened by the second flow path opening / closing mechanism 76, the cleaning liquid is supplied to each processing liquid sub-tank through the cleaning liquid supply hose 77. The processing solution sub tanks 732 to 735 are washed, introduced into the developing tank 42 in the same manner as the processing solutions described later, and discharged from the developing tank 42 to the outside.

  Here, with reference to FIGS. 4 and 5, a liquid discharge unit 90 (corresponding to a processing liquid discharge unit) that discharges the processing liquid stored in the developing tank 42 to the outside will be described.

  The liquid discharger 90 discharges the processing liquid and the cleaning liquid supplied to the developing tank 42 to the outside through the waste liquid hose 91, and has the same structure as the first flow path opening / closing mechanism 75 here. That is, the liquid discharge unit 90 opens and closes a pair of waste liquid hoses 91 connected to the liquid discharge ports 425a and 425b (FIG. 5) of the developing tank 42 and a flow path formed by the waste liquid hose 91. A waste liquid flow path opening / closing mechanism 92 that selects and opens one of the flow paths by the pair of waste liquid hoses 91 and discharges the processing liquid or cleaning liquid in the developing tank 42. It is.

  One waste liquid hose 91 may be provided, but here, two waste liquid hoses 91 are provided in order to make the waste liquid path of a specific processing liquid (for example, CD liquid) different from other processing liquids. That is, as shown in FIG. 5, a waste liquid hose 911 for discharging the CD liquid and a waste liquid hose 912 for discharging other processing liquid and cleaning liquid are provided. Thus, by making the waste liquid hose 911 for discharging the CD liquid different from the waste liquid hose 912 for discharging other processing liquid and cleaning liquid, the silver contained in the CD liquid can be reused as described above.

  The waste liquid flow path opening / closing mechanism 92 includes a fully closed state in which the flow paths by the two waste liquid hoses 91 are simultaneously closed, an individual open state in which the flow paths by the two waste liquid hoses 91 are separately opened, and two waste liquid hoses. By switching between the fully open state in which the flow path 91 is opened at the same time, each processing solution and the like that naturally falls from the developing tank 42 is circulated and stopped. Here, the waste liquid flow path opening / closing mechanism 92 has a crushing means 926 that crushes the waste liquid hose 91 to stop the flow of the processing liquid, and this crushing means 926 uses a cam mechanism to dispose the waste liquid hose. A mechanism is adopted in which a pressure is applied to 91 to crush the waste liquid hose 91 to close the flow path, and the flow path is opened by elastic recovery of the waste liquid hose 91 by removing the pressure.

  Specifically, the crushing means 926 rolls on the roller pressing cam 921 that rotates in correspondence with the two waste liquid hoses 91 and the outer peripheral surface of the roller pressing cam 921 to rotate the cam 921. A crushing roller 922 for crushing the waste liquid hose 91 according to the rotation angle, a roller urging means (not shown) for applying a biasing force for maintaining the crushing roller 922 in the retracted state from each waste liquid hose 91, and a roller pressing cam. The cam center shaft 923 which is the rotation center of 921, the drive unit 924 (FIG. 5) including a stepping motor whose output shaft is directly connected to the cam center shaft 923, and the crushing roller 922 across the waste liquid hose 91. And a pressing plate 925 that crushes the waste liquid hose 91 with the crushing roller 922 therebetween.

  The roller pressing cam 921 can take a pressing posture in which a crushing roller 922 is pressed against the side wall of each waste liquid hose 91 against a biasing force of a roller biasing means (not shown). It is like that.

  FIG. 9 is a flowchart showing an example of the operation of the photo processing apparatus. The following operations are performed by the control unit 100 (FIG. 2) that includes a CPU, ROM, RAM, and the like, and is composed of a personal computer or the like. Specifically, the operation of the entire photo processing apparatus is controlled by a CPU executing a program stored in advance in a ROM (or RAM).

  However, the positions of the movable members and the positions of the various tanks in FIGS. 1 to 5 are initially set to the following states. The cutter 21 is at the lower limit position, and the insertion guide 33 is set at an insertion position that is a position suitable for inserting the film 2 (the discharge guide 51 is at the retracted position). The developing reel 41 and the blower fan 62 are in a stopped state, and the liquid heating heater 78 is in an OFF state. Further, the water supply hose 77, the liquid supply hose 74, and the waste liquid hose 91 are all closed, and the developing tank 42 is empty. The sub tank main body 731 is at the lower limit position, and the sub tank main body 731 is in an empty state. Further, the film 2 stored in the cartridge 3 is set on the cartridge support portion 20 by opening the lid 11 of the housing 10, and the leading end of the film 2 is pulled out from the cartridge 3 and sandwiched between the first conveying roller pair 31. It shall be.

  First, it is determined whether or not a push button switch (not shown) disposed at an appropriate position of the housing 10 is turned on (step S101). If it is determined that it has not been turned on (NO in step S101), the process is set to a standby state. When it is determined that it is turned on (YES in step S101), driving of the driving rollers 311 and 321 and the guide driving roller 333 is started, and the film 2 is pulled out from the cartridge 3 and transported to the developing reel 41 is started. At the same time (step S103), the development preparation process described later with reference to FIG. 11 is started (step S102). Then, it is determined whether or not the rear end of the film 2 has been detected by the film rear end sensor 324 (the film 2 has been pulled out from the cartridge 3 to the rear end) (step S105). Specifically, the film trailing edge sensor 324 detects whether or not the rotation of the driven roller 322 is stopped although the driving roller 321 of the second transport roller pair 32 is rotating, and the driven roller 322 When the rotation is stopped, the trailing edge of the film is detected.

  If it is determined that the rear end of the film 2 has not been detected (NO in step S105), the conveyance process is continued. If it is determined that the rear end of the film 2 is detected (YES in step S105), the driving rollers 311 and 321 and the guide driving roller 333 are stopped, and the conveyance of the film 2 to the developing reel 41 is stopped. (Step S107). Then, the lower blade of the cutter 21 is raised, and the rear end portion of the film 2 is cut (step S109). Next, driving of the driving rollers 311 and 321 and the guide driving roller 333 is started again, and conveyance of the film 2 to the developing reel 41 is resumed (step S111).

  Next, it is determined whether or not the rear end of the film 2 cut by the cutter 21 has reached the position of the insertion guide 33 (step S113). Whether the rear end of the film 2 has reached the position of the insertion guide 33 is determined by, for example, arranging a detection switch or the like having an action rod that can be freely moved in and out of the film conveyance path. Can be used. If it is determined that the rear end of the film 2 has not reached the position of the insertion guide 33 (NO in step S113), the conveyance process is continued. When it is determined that the rear end of the film 2 has reached the position of the insertion guide 33 (YES in step S113), time measurement is started by a timer or the like provided in the control unit 100, and a predetermined time set in advance. It is determined whether T1 (for example, 10 seconds) has elapsed (step S115). If it is determined that the predetermined time T1 has not elapsed (NO in step S115), the process is set to a standby state. When it is determined that the predetermined time T1 has elapsed (YES in step S115), the driving of the drive rollers 311 and 321 of the first transport unit 30 is stopped, and the direction opposite to the spiral direction of the guide groove 412a (see FIG. The rotation of the developing reel 41 is started counterclockwise at 2 (step S117).

  At substantially the same time as the developing reel 41 is rotated, the insertion guide 33 and the discharge guide 51 are moved from the initial insertion position to the development position (the position where the insertion guide 33 and the discharge guide 51 are retracted). (Step S119).

  Next, when the processes of step S119 and step S102 are completed, a development process described later with reference to FIG. 12 is started (step S121), and a cleaning preparation process described later with reference to FIG. 14 is started (step S122). . Next, when the developing process is completed, the rotation of the developing reel 41 is stopped as shown in FIG. 10 (step S123). Then, the discharge guide 51 is moved to the discharge position (step S125).

  Subsequently, the developing reel 41 is rotated in the opposite direction to that during the developing process, that is, in the spiral direction of the guide groove 412a (clockwise in FIG. 2) (step S127). During the rotation of the developing reel 41, the rear end of the film protruding from the film insertion port 411 of the developing reel 41 (hereinafter, the rear end of the film 2 becomes the leading end in the transport direction. Is locked to the second swing member 512 of the discharge guide 51. Then, it is determined whether or not the leading end of the film 2 is on the discharge guide 51 (on the second swinging member 512) (the cueing of the film 2 has been completed on the discharge guide 51) (step S129). ). The determination as to whether or not the front end of the film 2 is placed on the discharge guide 51 is made by, for example, using an optical sensor (for example, a transmissive photo interrupter) that detects the presence or absence of the film 2 at an appropriate position of the discharge guide 51. This can be done using the signal from this sensor. If it is determined that the leading edge of the film 2 is not on the discharge guide 51 (NO in step S129), the rotation of the developing reel 41 is continued. If it is determined that the leading edge of the film 2 is on the discharge guide 51 (YES in step S129), the rotation of the developing reel 41 is stopped (step S131). In a state in which the rotation of the developing reel 41 is stopped, the position where the film insertion port 411 substantially faces the film introduction port 515 of the discharge guide 51 (more specifically, the developing reel 41 is slightly more than the film insertion port 411 than the facing position). At a position close to the downstream side in the rotation direction.

  Then, the insertion guide 33 and the discharge guide 51 are moved from the discharge position to the insertion position, whereby the first swing member 511 of the discharge guide 51 is pressed (the leading end of the film 2 is held by the guide drive roller pair 513). (Step S133). Here, when the first swing member 511 is pressure-bonded, the guide drive roller pair 513 is also pressed, and thereby the width direction end of the film 2 is peeled off from the guide groove 412a of the developing reel 41 with the film 2 interposed therebetween. However, the film 2 is discharged from the developing reel 41 and conveyed toward the next squeeze roller pair 52.

  Next, the guide drive roller pair 513 and the squeeze roller pair 52 are driven to rotate, and the conveyance of the film 2 from the developing reel 41 to the drying reel 61 is started (step S135).

  Then, it is determined whether or not the leading end of the film 2 has reached the drying reel 61 (step S137). The determination as to whether or not the front end of the film 2 has reached the drying reel 61 is made, for example, by arranging an optical sensor (for example, a transmissive photo interrupter) that detects the presence or absence of the film 2 at an appropriate position on the drying reel 61. And it can carry out using the signal from this sensor. If it is determined that the leading edge of the film 2 has not reached the drying reel 61 (NO in step S137), the conveyance process is continued. If it is determined that the leading edge of the film 2 has reached the drying reel 61 (YES in step S137), the drying heater and fan are turned on (step S139). Then, it is determined whether or not the rear end of the film 2 has reached the drying reel 61 (step S141). Whether or not the rear end of the film 2 has reached the drying reel 61 is determined by, for example, arranging an optical sensor (for example, a transmissive photo interrupter) that detects the presence or absence of the film 2 at an appropriate position on the drying reel 61. And using the signal from this sensor. Or you may carry out by detecting passage of the rear end of a film with the above-mentioned sensor which detects a front end. If it is determined that the rear end of the film 2 has not reached the drying reel 61 (NO in step S141), the conveyance process is continued. When it is determined that the rear end of the film 2 has reached the drying reel 61 (YES in step S141) and the processing in step S122 is completed, the driving of the guide drive roller pair 513 and the squeeze roller pair 52 is stopped. Then, the conveyance of the film 2 from the developing reel 41 to the drying reel 61 is stopped (step S143).

  Then, a cleaning process to be described later with reference to FIG. 15 is started (step S149), and time measurement is started by a timer or the like provided in the control unit 100, and a preset predetermined time T2 (for example, 30 seconds: It is determined whether or not the time required for drying the film 2 has elapsed (step S145). If it is determined that the predetermined time T2 has not elapsed (NO in step S145), the drying process is continued. If it is determined that the predetermined time T2 has elapsed (YES in step S145), the drying heater and the fan are turned off (step S147), and the process is terminated. The film 2 that has been dried is taken out by the operator with the lid 12 opened while being wound around the drying reel 61.

Then, it is determined whether or not the sub tank main body 731 has reached the upper limit position (step S205). When it is determined that the sub tank main body 731 has not reached the upper limit position (NO in step S205), the ascending process is continued. If it is determined that the sub tank main body 731 has reached the upper limit position (YES in step S205), the sub tank main body 731 starts to be lowered using the sub tank lifting mechanism 80 (step S207). Then, it is determined whether or not the sub tank main body 731 has reached the lower limit position (step S209). If it is determined that the sub tank main body 731 has not reached the lower limit position (NO in step S209), the descending process is continued.

If it is determined that the predetermined time TS5 has elapsed (YES in step S405), the water supply hose 77 is closed (step S407), and the process is returned.

  FIG. 15 is a detailed flowchart showing an example of the cleaning process performed in step S149 of the flowchart shown in FIG. The cleaning process is a process for cleaning the processing liquid adhering to the sub tank main body 731, the developing tank 42, the developing reel 41, and the like. First, the clockwise rotation of the developing reel 41 is started (step S501). Then, the liquid supply hose 74 (CD supply hose 742, BL supply hose 743, FIX supply hose 744 and STB supply hose 745) is opened (step S503). Next, timing is started by a timer or the like provided in the control unit 100, and a predetermined time TC1 (for example, 30 seconds: CD sub tank 732, BL sub tank 733, FIX sub tank 734, and STB sub tank) is set. It is determined whether or not the flow of the cleaning liquid from 735 to the developing tank 42 and the time required for cleaning the developing tank 42 have elapsed (step S505). If it is determined that the predetermined time TC1 has not elapsed (NO in step S505), the process is set to a standby state.

  As described above, according to the above configuration, the cleaning liquid supply means 70B for supplying the cleaning liquid for cleaning the flow path of the processing liquid from the processing liquid sub tanks 732 to 735 to the developing tank 42 is provided. As a result of cleaning the processing liquid supply path so that the processing liquid does not exist, mixing of another processing liquid into one processing liquid, deterioration of the processing liquid in the liquid transmission path, crystallization, Can be prevented so that the quality of the development processing does not deteriorate.

  Further, according to the above configuration, the cleaning liquid supply means cleans the flow path of the processing liquid with the cleaning liquid every time processing of one film or one photographic paper is completed. Can be managed with high accuracy.

  Further, according to the above configuration, the cleaning liquid stored in the cleaning liquid subtank 736 is filled into the processing liquid subtanks 732 to 735 by free fall from the cleaning liquid subtank 736. Therefore, the cleaning liquid subtank 736 and each processing liquid are filled. An expensive pump mechanism is not required between the sub-tanks 732 to 735, and the cost for manufacturing the photographic processing apparatus is greatly reduced.

  In addition, the cleaning liquid can be filled in each of the processing liquid sub-tanks 732 to 735 after the cleaning liquid sub-tank 736 is accurately weighed for one batch (a fixed amount), so the amount of the cleaning liquid can be reduced with a simple configuration. It can be precisely measured and managed, and does not require expensive measuring devices and control devices.

  Further, according to the above configuration, the elevating means 80 brings the cleaning liquid replenishment tank 716 and the cleaning liquid subtank 736 close to each other so that the top of the valve opening pin 736b of the cleaning liquid subtank 736 is non-returned to the cleaning liquid replenishing valve section 79B. By interfering with the lower surface of the valve, the check valve is opened and the cleaning liquid replenishing tank 716 and the cleaning liquid subtank 736 are separated from each other so that the top of the valve opening pin 736b is opposite to the cleaning liquid replenishing valve section 79B. Since the check valve is closed by retreating downward from the lower surface of the stop valve, the cleaning liquid can be supplied from the cleaning liquid replenishment tank 716 to the cleaning liquid sub tank 736 by free fall as necessary. As a result, between the cleaning liquid replenishment tank 716 and the cleaning liquid sub tank 736, there is an expensive pump mechanism having a drive unit, and an accompanying pump mechanism. That the measuring device and a control device and is not required, the cost of production of the photo processing device is further reduced.

  When the liquid level of the cleaning liquid reaches the liquid discharge port of the check valve, the replacement of the cleaning liquid in the cleaning liquid replenishment tank 716 with the external air is stopped, and the replenishment of the cleaning liquid to the cleaning liquid sub-tank 736 is stopped. Therefore, the cleaning liquid upper limit detecting means of the cleaning liquid sub-tank 736 and the control device for operating the cleaning liquid replenishing valve 79B in accordance with the upper limit detecting means are not required, and the cost for manufacturing the photographic processing apparatus is further reduced.

  As described above, according to the present invention, in a photographic processing apparatus for developing a film or photographic paper, a new expensive pump mechanism and a measuring device and a control device associated with the pump mechanism are not added. There is a remarkable effect that it is possible to provide a photographic processing apparatus capable of preventing the deterioration of the processing liquid and crystallization so that the quality of the development processing does not deteriorate.
