Description

  The present invention relates to a film developing apparatus that performs development by bringing a long film into contact with a processing liquid.

  Photographic films are generally developed by immersing them sequentially in a plurality of types of processing solutions and reacting the photosensitive agent in the emulsion surface provided on one side of the film with the processing solution. . Conventionally, as a film developing apparatus that automatically executes the development processing of such a photographic film, a plurality of processing tanks for storing processing liquids are provided for each processing liquid, and the film is stopped at a transport unit constituted by a transport roller or the like. There is a known one that is continuously conveyed without being developed and is developed by being immersed in a processing solution in each processing tank.

  However, in such an apparatus, a plurality of processing tanks are provided for each processing liquid, and a transport roller is also provided in each processing tank. Therefore, the processing tank is enlarged and the processing liquid stored in the processing tank is stored. Since many films can be processed with one filling, if a long time is required for developing the next film after developing one film, the processing solution deteriorates during that time. there were. In particular, in recent years, with the spread of digital cameras, the number of films to be processed per day has decreased, and the processing liquid stored in the processing tank has to be managed for several days, which is complicated. It becomes difficult to maintain the properties of the treatment liquid within an appropriate range.

On the other hand, in order to eliminate the need for management of the processing liquid, there has been proposed an apparatus that makes it unnecessary to manage the properties of the processing liquid by making the processing liquid disposable for each film (see Patent Document 1). This apparatus has a treatment tank having a sword sheath shape. By supplying, circulating, and discharging the treatment liquid to the treatment tank, the amount of the treatment liquid to be used is reduced. Each film can be made disposable.

  However, the apparatus described in Patent Document 1 also requires a mechanism for inserting a long film into a treatment tank having a sword sheath shape (the retracting means described in Patent Document 1), and the entire apparatus. It has become an obstacle to downsizing. Moreover, in order to insert the film into a sheath-like treatment tank so that a predetermined gap is provided between the front and back surfaces of the film and the inner wall surface of the treatment tank, the sheath-like treatment tank is made of the film. There was a problem of increasing in the thickness direction. This problem not only hinders downsizing of the entire apparatus, but also increases the amount of processing liquid filled in the processing tank, thereby increasing the cost required for development processing.

  In particular, a film wound on a cartridge spool or the like has a curl (longitudinal warpage), and if the gap between the front and back surfaces of the film and the inner wall surface of the processing tank is small, the film will be in the processing tank. Since there is a risk that quality defects such as uneven development may occur due to contact with the wall surface, it is necessary to design the dimensions of the processing tank (especially the dimension in the thickness direction of the film) so that this contact does not occur. There is a problem that the tank is further enlarged.

  The present invention has been made to solve the above-described problems, and provides a film developing apparatus that reduces the size of the apparatus while maintaining the quality of the developing process and suppresses the amount of processing liquid used for the developing process.

And the side wall portion 5122 is formed in a taper shape that spreads outward as it goes to the first swing member 511, whereby the rear end portion of the film 2 accommodated in the developing reel 41 is tapered side wall portion 5122. And the film 2 is reliably pulled out from the developing reel 41 while correcting the posture of the film 2. Further, the second swing member 512 is provided with an inverted U-shaped engagement portion 512a at an end further downstream from the swing center axis. The engaging portion 512a is engaged with a connecting pin 552e provided at the tip of a swinging rod 552, which will be described later, of the common guide swinging mechanism 55, and the developing reel 41 is moved along with the swinging of the swinging rod 552. It is supposed to slide in the direction of approaching and separating.

It is supposed to come and go with it. When the discharge guide 51 is at the discharge position, both rollers of the guide drive roller pair 513 are separated to transfer the film 2 from the developing reel 41. After this transfer, the discharge guide 51 moves to the insertion position, Both rollers of the guide drive roller pair 513 are pressure-bonded, whereby the film 2 is sandwiched and conveyed. As shown in FIG. 6, the guide drive roller pair 513 is a distance from the outer peripheral edge of the developing reel 41 when the discharge guide 51 is at the discharge position (a distance indicated by L2 in FIG. 6; for example, L2 = 20 mm). Is set shorter than the distance L1 from the guide driving roller 333 and the guide driven roller 334 to the outer peripheral edge of the developing reel 41 (L1> L2).

  Next, the common guide swing mechanism 55 will be described with reference to FIGS. FIG. 7 is a schematic front view showing the common guide swinging mechanism 55. The solid line indicates the case where the guides 33 and 51 are in the discharge position, and the double dotted line indicates the case where the guides 33 and 51 are in the insertion position.

  The common guide rocking mechanism 55 includes a rocking cam 551, a rocking rod 552 that rocks back and forth along the conveying direction by the rocking cam 551, and a biasing member that biases the rocking rod 552 forward in the conveying direction.

The drive cam 56 rotates the swing cam 551 so that the insertion guide main body 33a and the discharge guide are provided. The main body 51a is swung.

  Specifically, the swing cam 551 has a cam body 551a formed in a fan shape when viewed from the side, and a cam rotation center shaft 551b of the cam body 551a. The cam body 551a has cam noses 5511 to 5513 in which the length from the cam rotation center shaft 551b to the outer peripheral edge has three steps of long and short. In the present embodiment, these cam noses 5511 to 5513 are connected by a smooth curve. Thus, it is formed in a generally fan shape in side view. Then, as shown in FIG. 8, these cam noses 5511 to 5513 come into contact with a later-described rotating roller 552c of the swing rod 552, so that the insertion guide 33 and the discharge guide 51 are in the insertion position, the development position, and the discharge position. The position can be changed to three positions. That is, when the cam nose 5511 having the shortest length from the cam rotation center shaft 551b to the outer peripheral edge contacts the rotation roller 552c of the swing rod 552, the insertion guide body 33a and the discharge guide body 51a are in the insertion position ( When the intermediate cam nose 5512 contacts the rotary roller 552c, the insertion guide body 33a and the discharge guide body 51a are in the developing position (see FIG. 8B). When the cam nose 5513 having the longest length comes into contact with the rotary roller 552c, the insertion guide main body 33a and the discharge guide main body 51a are in the discharge position (see FIG. 8C).

The swing rod 552 is biased toward the swing cam 551 by a biasing portion 553 (here, a helical spring) locked to the connecting rod 552d, and the rotating roller 552c is rotated around the swing cam 551. The surface is in pressure contact. Accordingly, when the swing cam 551 rotates, the rotary roller 552c rolls on the peripheral surface of the cam body 551a, and thereby the swing rod 552 swings in the proximity direction or the separation direction with respect to the developing unit 40.

  The slide rod 554 has a pair of widthwise slide rod main bodies 554a that are elongated along the conveying direction and whose downstream end is pivotally supported by the swing rod 552, and are slightly above the middle in the conveying direction of each slide rod main body 554a.

The guide protrusion 554b has an inclined guide surface 554d that is inclined upward in the transport direction. When the rotating roller 514 of the discharge guide 51 contacts the guide surface 554d, the slide rod 554 slides back and forth in the transport direction. The rotary roller 514 of the discharge guide 51 rolls along the inclined guide surface 554d, and thereby the first swing member 511 of the discharge guide 51 swings up and down.

  Here, the detailed structure of the side plate 412 of the developing reel 41 will be described with reference to FIG. 11A is a perspective view of the side plate 412, FIG. 11B is a cross-sectional view taken along line AA of the side plate 412, and FIG. 11C is a cross-sectional view taken along line BB of the side plate 412. As shown in (a), the side plate 412 is formed with guide support bars 412d (corresponding to guide support portions) that support the film guide groove 412a in the radial direction radially from the reel center axis 413.

  That is, (b) is a cross-sectional view of a position corresponding to the guide support bar 412d of the side plate 412, and (c) is a cross-sectional view of the side plate 412 at a position where the guide support bar 412d is not provided. As shown in (b), the groove in the front view spiral shape having a substantially square shape in cross section in which the film guide groove 412a is formed is integrally connected by a guide support bar 412d. Further, as shown in (c), the substantially square-shaped groove in the cross-sectional view in which the film guide groove 412a is formed is partially formed through the side plate 412 as a liquid passage hole 412c. The processing liquid can freely flow in and out between the inner side (left side of the drawing: film 2 side) and the outer side of the side plate 412 via 412c.

  In this way, the side plate 412 is formed with a plurality of liquid passage holes 412c so that the treatment liquid can freely flow in and out between the inner side and the outer side of the side plate 412. The processing liquid is easily brought into contact with the film 2 held in step 1, and is further appropriately developed (with good quality).

  In addition, film guide grooves 412a are formed on the opposing surfaces of the side plate 412 of the developing reel 41 at substantially equal intervals in the radial direction, and the processing liquid is supplied from the liquid passage holes 412c formed in the film guide grooves 412a. 41 flows in and out between the inside and the outside of the film 41, so that the emulsion surface 2a of the film 2 and the processing liquid are reliably brought into contact with each other and further properly developed (with good quality).

  Further, since the processing liquid flows in and out between the inside and the outside of the developing reel 41 from the liquid passage hole 412c formed by approximately one turn on the inner side in the radial direction of the inner circumference of the film guide groove 412a, the film The emulsion surface 2a on the inner side of the front end side (inner winding) of the sheet 2 is also appropriately contacted with the processing solution and further appropriately (with good quality) developed.

  That is, the liquid passage hole 412c is formed by approximately one turn on the inner side in the radial direction of the inner periphery of the film guide groove 412a (that is, approximately one turn or more on the inner side in the radial direction of the inner periphery of the film guide groove 412a Therefore, the emulsion surface 2a on the inner side of the leading end side (inner winding) of the film 2 is compared with the emulsion surface 2a of the other part of the film 2 (outer winding portion, etc.) Insufficient contact (or excessive contact with the processing solution) is prevented, and the occurrence of uneven development in the longitudinal direction of the film 2 is suppressed.

  In addition, since the guide support bar 412d is formed radially from the reel center shaft 413 on the side plate 412 of the developing reel 41, the side plate 412 in which the film guide groove 412a is formed is integrally connected, and the film guide groove 412a Deformation is suppressed. Further, since the liquid passage hole 412c is formed in a substantially arc shape in the film guide groove 412a, the liquid guide hole 412c having a large cross-sectional area is supported while the film guide groove 412a is securely supported in the radial direction by the guide support bar 412d. Since the film 2 can be formed, the film 2 is further properly developed (to a good quality).

Specifically, the drying unit 60 is disposed on the drying reel 61 that accommodates the film 2 that has been conveyed from the second conveyance unit 50 by spirally winding the film 2 at a predetermined pitch, and on the back side of the drying reel 61. And a blower fan 62 with a heater. The film 2 is dried by blowing warm air between the films 2 held by the drying reel 61.

  Here, the temperature control method of the drying unit 60 will be briefly described. The drying unit 60 is provided with a temperature sensor (not shown) that measures the ambient temperature in the drying reel 61, and the operation of the blower fan 62 with heater is controlled using the temperature measured by the temperature sensor. . For example, when the temperature measured by the temperature sensor is 60 ° C. or less, the heater and the blower fan 62 are continuously turned on, and when the temperature measured by the temperature sensor is more than 60 ° C. and less than 80 ° C., When the heater and the blower fan 62 are intermittently turned “ON” (for example, “ON” and “OFF” are switched every second) and the temperature measured by the temperature sensor is 80 ° C. or higher, The heater and the blower fan 62 are turned off. By performing such control, the atmospheric temperature in the drying reel 61 is controlled within a range of approximately 60 to 80 ° C., so that the film 2 can be suitably dried. The temperature control of the ambient temperature in the drying reel 61 described above is performed by the control unit 100 described later.

The discharge of the cleaning liquid from the replenishing tank 716 is stopped. That is, when the liquid level reaches the discharge port of the replenishing tank 716, the supply of air from the discharge port is cut off, and the negative pressure acts on the replenishing tank 716 to measure the cleaning liquid. The height of the valve opening pin 736a is set in consideration of the amount of cleaning liquid to be replenished in the sub tank 736.

  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 applies a pressure to the cleaning liquid supply hose 77 from its side surface by using a cam mechanism to crush the cleaning liquid supply hose 77 to close the flow path, and removes the pressure. Thus, a mechanism for opening the flow path by elastic restoration of the cleaning liquid supply hose 77 is employed. 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, and to supply all cleaning liquids. It is configured to be switchable to a posture separating from the 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 sub-tanks 732 to 735 are supplied to 732 to 735, washed, introduced into the developing tank 42 in the same manner as each processing liquid described later, and discharged from the developing tank 42 to the outside.

  Each of the processing liquid sub tanks 732 to 735 is provided with inlets 732a to 735a 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. Further, each of the processing liquid sub tanks 732 to 735 has valve opening pins 732b to 735b for opening the check valves 79 by pressing the check valves 79 of the processing liquid replenishing tanks 712 to 715 from below on the bottom surfaces thereof. Is provided. When the check valve 79 is opened by these valve opening pins 732b to 735b, the respective processing liquids are discharged from the discharge ports of the replenishing tanks 712 to 715 to the processing liquid sub tanks 732 to 735, and the liquid levels of the respective processing liquids. At the time when the discharge ports of the replenishing tanks 712 to 715 reach the discharge ports, the discharge of the processing liquids from the replenishing tanks 712 to 715 is stopped. Accordingly, the heights of the valve opening pins 732b to 735b are set in consideration of the amount of the processing liquid to be replenished to the processing liquid sub tanks 732 to 735. Here, the amount of processing liquid to be replenished to the processing liquid sub-tanks 732 to 735 (that is, the amount of processing liquid supplied to the developing tank 42) is the inner end of the film guide groove 412a while the developing reel 41 rotates once. Is set to a depth at which the developing tank 42 is immersed in the processing liquid filled in the developing tank 42 and at a depth at which all of the developing reel 41 is not immersed.

  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), 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 74 a is connected to the liquid supply port 424 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 switches 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 processing liquids that naturally fall from the processing liquid sub tanks 732 to 735 toward the developing tank 42 are circulated and stopped.

  Here, the first flow path opening / closing mechanism 75 uses a cam mechanism to apply pressure to the liquid supply hose 74 from its side surface to crush the hose 74 and close the flow path, and remove the pressure. Therefore, a mechanism for opening the flow path by elastic recovery of the liquid supply hose 74 is adopted. Specifically, as shown in FIGS. 3 and 4, the first flow path opening / closing mechanism 75 includes a roller pressing cam 751 that is provided according to each liquid supply hose 74 and is driven to rotate, and the roller pressing cam 751. The crushing roller 752 that rolls the outer peripheral surface of the cam 751 to crush the liquid supply hose 74 according to the rotation angle of the cam 751, the cam center shaft 753 that is the rotation center of all the cams 751, and the output shaft is the cam. A drive unit 754 composed of a stepping motor or the like directly connected to the central shaft 753, a pressing plate 755 that is disposed opposite to the crushing roller 752 with the liquid supply hose 74 interposed therebetween, and is crushed with the hose 74 interposed between the roller 752 It has.

  The roller pressing cam 751 is formed as a substantially disk body, and a part of the outer peripheral surface is recessed radially inward 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.

  On the other hand, the liquid discharge unit 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 includes a pair of waste liquid hoses 91 connected to the liquid discharge ports 425a and 425b of the developing tank 42, and a waste liquid flow path that opens and closes a flow path formed by the waste liquid hose 91. An opening / closing mechanism 92 is provided, and the waste liquid flow path opening / closing mechanism 92 selects and opens one of the flow paths by the pair of waste liquid hoses 91 to discharge the processing liquid or cleaning liquid in the developing tank 42.

  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, 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.

  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 applies a pressure to the waste liquid hose 91 from its side surface by using a cam mechanism, thereby crushing the waste liquid hose 91 to close the flow path and removing the pressure. A mechanism for opening the flow path by elastic recovery of the waste liquid hose 91 is employed.

  12 and 13 are flowcharts showing an example of the operation of the film developing apparatus. The following operations are performed by the control unit 100 that includes a CPU, ROM, RAM, and the like and includes a personal computer or the like. Specifically, the operation of the entire film developing apparatus 1 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. (Step S103), and development preparation processing described later with reference to FIG. 14 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).

  The insertion guide 33 and the discharge guide 51 are moved from the initial insertion position as shown in FIG. 8A to the development position as shown in FIG. 8B at substantially the same time as the development reel 41 is rotated. It is moved to (position where the insertion guide 33 and the discharge guide 51 are retracted) (step S119). Specifically, referring to FIGS. 7 and 8, the cam 56 for rotation is driven to rotate by the drive unit 56, and the cam nose 5512 having an intermediate length is moved from the state in which the shortest cam nose 5511 is in contact with the rotary roller 552c. The state is brought into contact with the rotating roller 552c. Along with this, the swing bar 552 swings toward the rear in the film transport direction centering on the lower end thereof, whereby the slide bar 554 also slides in the same direction. As the swinging rod 552 swings, the second swinging member 512 of the discharge guide 51 also slides toward the developing reel 41 via the connecting rod 552d. As the slide rod 554 slides, the first and second swing members 331 and 332 of the insertion guide 33 swing in a direction away from the developing reel 41 via the engagement pin 336, and the discharge guide. 51 of the first swing member 511 swings in a direction away from the developing reel 41 as the rotary roller 514 is guided by the inclined guide surface 554d of the guide protrusion 554b of the slide rod 554. As a result, the insertion guide 33 and the discharge guide 51 are moved from the insertion position to the development position.

  Next, when the processing of step S119 and step S102 is completed, development processing described later with reference to FIGS. 15 and 16 is started (step S121). Next, when the development process is completed, a cleaning preparation process described later with reference to FIG. 17 is started (step S122), and the rotation of the development reel 41 is stopped as shown in FIG. 13 (step S123). Then, the discharge guide 51 is moved to the discharge position as shown in FIG. 8C (step S125). 7 and 8, the longest cam nose 5513 from the state in which the swing cam 551 is rotationally driven by the drive unit 56 and the intermediate cam nose 5512 is in contact with the rotary roller 552c. Shifts to a state of abutting on the rotating roller 552c. Along with this, the swing bar 552 further swings toward the rear in the film transport direction centering on the lower end thereof, whereby the slide bar 554 also slides in the same direction. As the swinging rod 552 swings, the second swinging member 512 of the discharge guide 51 further advances toward the developing reel 41 via the connecting rod 552d. As the slide rod 554 slides, the first and second swinging members 331 and 332 of the insertion guide 33 swing further away from the developing reel 41 via the engagement pin 336 and discharged. The first swing member 511 of the guide 51 swings in a direction further away from the developing reel 41 as the rotary roller 514 is guided by the inclined guide surface 554d of the guide protrusion 554b of the slide rod 554. As a result, the insertion guide 33 and the discharge guide 51 are moved from the development position to the discharge position.

  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 where the rotation of the developing reel 41 is stopped, as shown in FIG. 9, the film insertion port 411 is substantially opposed to the film introduction port 515 of the discharge guide 51 (more specifically, the film insertion port 411 is opposed to the opposite side). A position slightly closer to the downstream side in the rotation direction of the developing reel 41 than the position). Further, in the stopped state of the developing reel 41 in step S131, braking by drag torque is applied by the developing reel drive unit 43 instead of brake braking. That is, in step S135, when the guide drive roller pair 513 and the squeeze roller pair 52 are rotationally driven, the developing reel 41 is rotated while being pulled and braked by the film 2.

  Then, the insertion guide 33 and the discharge guide 51 are moved from the discharge position shown in FIG. 8C to the insertion position shown in FIG. 8A, whereby the first swing member 511 of the discharge guide 51 is pressure-bonded ( The leading end of the film 2 is clamped by the guide drive roller pair 513 (step S133). Here, when the first swinging member 511 is pressure-bonded, the guide drive roller pair 513 is also brought into pressure contact with the film 2 so that the end in the width direction of the film 2 is placed on the developing reel 41 as shown in FIG. The film 2 is discharged from the developing reel 41 while being peeled off from the guide groove 412a 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. 18 is started (step S149), and time measurement is started by a timer or the like provided in the control unit 100, and a predetermined time T2 set in advance (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 being opened while being wound around the drying reel 61.

  FIG. 14 is a detailed flowchart showing an example of the development preparation process performed in step S102 of the flowchart shown in FIG. In the development preparation process, the sub tank main body 731 is moved up and down to move from the CD replenishing tank 712, the BL replenishing tank 713, the FIX replenishing tank 714, the STB replenishing tank 715, and the cleaning liquid replenishing tank 716, respectively. CD sub-tank 732, BL sub-tank 733, FIX sub-tank 734, STB sub-tank 735 and cleaning liquid sub-tank 736 are set to a predetermined amount (for example, CD sub-tank 732, BL sub-tank 733, FIX sub-tank 734 and STB This is a process of replenishing 50 ml of liquid to the sub-tank 735 and 50 ml of liquid to the cleaning liquid sub-tank 736.

  First, the water supply hose 77 and the liquid supply hose 74 are all closed (step S201). Then, the sub tank main body 731 starts to be lifted using the sub tank lifting mechanism 80 (step S203). 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 sub tank main body 731 has reached the lower limit position (YES in step S209), the descent of the sub tank main body 731 is stopped (step S211). And all the waste liquid hoses 91 are made into a closed state (step S213), and a process is returned.

  15 and 16 are detailed flowcharts showing an example of the developing process performed in step S121 of the flowchart shown in FIG. The development process is a process in which the processing liquid is supplied to the developing tank 42 in the order of CD, BL, FIX, and STB, and the film 2 is immersed in each processing liquid to react each processing liquid with the emulsion of the film 2. Before the processing of the detailed flowcharts shown in FIGS. 15 and 16 starts, the rotation of the developing reel 41 is started in step S117 of the flowchart shown in FIG.

  First, the CD supply hose 742 is opened (step S301). Then, timing is started by a timer or the like provided in the control unit 100, and a predetermined time TS1 (for example, 195 seconds: the flow of the CD liquid from the CD sub tank 732 to the developing tank 42 and the film 2) Whether or not the time required for the reaction between the emulsion and the CD solution has elapsed (step S303). If it is determined that the predetermined time TS1 has not elapsed (NO in step S303), the process is set to a standby state. If it is determined that the predetermined time TS1 has elapsed (YES in step S303), the CD waste liquid hose 911 is opened (step S305), and the CD liquid is discharged from the developing tank. Then, the time measurement is started by a timer or the like provided in the control unit 100, and whether or not a predetermined time TR1 (for example, 5 seconds: time required for the CD liquid to flow out from the developing tank 42) has elapsed has elapsed. Is determined (step S307). If it is determined that the predetermined time TR1 has not elapsed (NO in step S307), the process is set to a standby state. If it is determined that the predetermined time TR1 has elapsed (YES in step S307), the waste liquid hose 91 (CD waste liquid hose 911 and non-CD waste liquid hose 912) is closed (step S309).

  Next, the BL supply hose 743 is opened (step S311). Then, timing is started by a timer or the like provided in the control unit 100, and a predetermined time TS2 (for example, 69 seconds: the flow of the BL processing liquid from the BL sub tank 733 to the developing tank 42, and the film It is determined whether or not the time required for the reaction between the emulsion No. 2 and the BL solution has elapsed (step S313). If it is determined that the predetermined time TS2 has not elapsed (NO in step S313), the process is set to a standby state. If it is determined that the predetermined time TS2 has elapsed (YES in step S313), the non-CD waste liquid hose 912 is opened (step S315), and the BL liquid is discharged from the developing tank. Then, the time measurement is started by a timer or the like provided in the control unit 100, and whether or not a predetermined time TR2 (for example, 5 seconds: time required for the BL liquid to flow out from the developing tank 42) has elapsed has elapsed. Is determined (step S317). If it is determined that predetermined time TR2 has not elapsed (NO in step S317), the process is set to a standby state. If it is determined that the predetermined time TR2 has elapsed (YES in step S317), the waste liquid hose 91 (CD waste liquid hose 911 and non-CD waste liquid hose 912) is closed (step S319).

  Next, as shown in FIG. 16, the FIX supply hose 744 is opened (step S321). Then, timing is started by a timer or the like provided in the control unit 100, and a predetermined time TS3 (for example, 138 seconds: the flow of the FIX liquid from the FIX sub-tank 734 to the developing tank 42, and the film 2 It is determined whether or not the time required for the reaction between the emulsion and the FIX solution has elapsed (step S323). If it is determined that the predetermined time TS3 has not elapsed (NO in step S323), the process is set to a standby state. If it is determined that the predetermined time TS3 has elapsed (YES in step S323), the non-CD waste liquid hose 912 is opened (step S325), and the FIX liquid is discharged from the developing tank. Then, the time measurement is started by a timer or the like provided in the control unit 100, and whether or not a predetermined time TR3 (for example, 5 seconds: time required for the FIX liquid to flow out of the developing tank 42) has elapsed has elapsed. Is determined (step S327). If it is determined that predetermined time TR3 has not elapsed (NO in step S327), the process is set to a standby state. If it is determined that the predetermined time TR3 has elapsed (YES in step S327), the waste liquid hose 91 (CD waste liquid hose 911 and non-CD waste liquid hose 912) is closed (step S329).

  Next, the STB supply hose 745 is opened (step S331). Then, timing is started by a timer or the like provided in the control unit 100, and a predetermined time TS4 (for example, 142 seconds: flow of the STB liquid from the STB sub tank 735 to the developing tank 42, and the film 2) It is determined whether or not the time required for the reaction between the emulsion and the STB solution has elapsed (step S333). When it is determined that the predetermined time TS4 has not elapsed (NO in step S333), the process is set in a standby state. If it is determined that the predetermined time TS4 has elapsed (YES in step S333), the non-CD waste liquid hose 912 is opened (step S335), and the STB liquid is discharged from the developing tank. Then, the time measurement is started by a timer or the like provided in the control unit 100, and whether or not a predetermined time TR4 (for example, 5 seconds: time required for the STB liquid to flow out from the developing tank 42) has elapsed has elapsed. Is determined (step S337). If it is determined that predetermined time TR4 has not elapsed (NO in step S337), the process is set to a standby state. If it is determined that the predetermined time TR3 has elapsed (YES in step S337), the waste liquid hose 91 (CD waste liquid hose 911 and non-CD waste liquid hose 912) is closed (step S339), and the process returns. Is done.

  FIG. 17 is a detailed flowchart showing an example of the cleaning preparation process performed in step S122 of the flowchart shown in FIG. The cleaning preparation process is a process for preparing a cleaning process that is a process for cleaning the processing liquid adhering to the sub-tank body 731, the developing tank 42, the developing reel 41, and the like. First, all the liquid supply hoses 74 are closed (step S401). Then, the water supply hose 77 is opened (step S403), and the flow of the cleaning liquid from the cleaning liquid sub tank 736 to the CD sub tank 732, the BL sub tank 733, the FIX sub tank 734, and the STB sub tank 735 is started. Next, timing is started by a timer or the like provided in the control unit 100, and a predetermined time TS5 (for example, 15 seconds: from the cleaning liquid sub tank 736 to the CD sub tank 732, the BL sub tank 733, and the FIX sub tank 734). Then, it is determined whether or not the time required for the cleaning liquid to flow into the STB sub tank 735 has elapsed (step S405). If it is determined that the predetermined time TS5 has not elapsed (NO in step S405), the process is set in a standby state. 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. 18 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. If it is determined that the predetermined time TC1 has elapsed (YES in step S505), the non-CD waste liquid hose 912 is opened (step S507). Then, timing is started by a timer or the like provided in the control unit 100, and whether or not a predetermined time TC2 (for example, 10 seconds: time required for the washing liquid to flow out from the developing tank 42) has elapsed has elapsed. A determination is made (step S509). If it is determined that the predetermined time TC2 has not elapsed (NO in step S509), the process is set in a standby state. If it is determined that the predetermined time TC2 has elapsed (YES in step S509), the rotation of the developing reel 41 is stopped (step S511), and the process is terminated.

  In this way, since the film 2 is developed while being inserted in the developing reel 41, the film developing apparatus 1 can be downsized. Further, since the processing liquid is filled in the developing tank 42 at a depth at which the inner end of the film guide groove 412a of the developing reel 41 is immersed in the processing liquid during one rotation of the developing reel 41, the film 2 has a full length. As the developing reel 41 rotates, it is immersed in the processing liquid and developed appropriately (with good quality).

  Further, the amount of the processing liquid filled in the developing tank 42 is an amount corresponding to the depth at which the inner end of the film guide groove 412a is immersed in the processing liquid while the developing reel 41 rotates once. Development processing with a small amount of processing solution becomes possible.

  Furthermore, since the inner wall shape of the developing tank 42 is substantially similar to the outer shape of the lower half of the developing reel 41 with the film 2 inserted, the amount of wasted processing liquid that does not contribute to development is reduced. . Therefore, development processing with a smaller amount of processing liquid becomes possible.

  In addition, since the developing tank 42 has substantially the same volume as the processing liquid supplied by the liquid supply unit 70, the developing tank 42 can be downsized.

  In addition, since a plurality of types of processing liquids are sequentially filled in the developing tank 42 by the liquid supply unit 70 and the like, even when developing using a plurality of types (here, four types) of processing liquids in order, a small amount is required. Development processing with this processing solution becomes possible.

  Furthermore, since the film 2 is inserted into the inside along the film guide groove 412a from one place on the outer peripheral edge of the developing reel 41 by the first transport unit 30, an operator or the like can insert the film 2 into the developing reel 41. It becomes unnecessary.

  Further, since the film 2 stored in the cartridge 3 is pulled out and inserted into the developing reel 41 by the first transport unit 30, the operation of inserting the film 2 into the developing reel 41 becomes unnecessary. Further, since the transport path of the film 2 in the first transport unit 30 is changed to a substantially right angle in the middle, the apparatus can be downsized. Further, when the direction is changed in the direction opposite to the winding direction of the film 2 in the cartridge 3 (when the film 2 is bent in the direction opposite to the warping in the longitudinal direction of the film 2 in the cartridge 3), the winding wrinkles should be reduced. Is possible.

  In addition, since the film 2 developed by the developing reel 41 is transported to the drying unit 60 and dried, after the film 2 is transported to the drying unit 60, development processing of the next film 2 may be started. It becomes possible and processing is performed efficiently.

  Further, since the drying process is performed in a state where the film 2 is inserted into the drying reel 61, the apparatus can be further downsized. Further, the drying reel 61 of the drying unit 60 is a spiral film guide from one place on the outer peripheral edge toward the center between the substantially disk-shaped side plates that are arranged side by side at substantially the film width and have a plurality of holes. Since the grooves are formed at least for the length of the film, the film 2 is easily inserted into the drying reel 62 by the second transport unit 50. Furthermore, since the air for film drying is sent from the side surface of the drying reel 61 by the blower fan 62 and a plurality of holes are formed in the side plate of the drying reel 61, the drying process is efficiently performed.

  In addition, since the developing tank 42 has a minimum volume capable of storing the processing liquid having a depth supplied by the liquid supply unit 70, the developing tank 42 can be downsized.

  In addition, this invention can take the following aspects.

  (A) Although the case where the film 2 is a 135 mm film has been described in the present embodiment, the film 2 may be in a form of another standard film (for example, a so-called APS standard film). When the film 2 is an APS standard film, the cutter 21 and the film rear end detection sensor 324 for cutting the rear end of the film 2 are not necessary, and the apparatus is simplified.

  (B) In the present embodiment, the case where the treatment liquid is composed of four types of the CD liquid, the BL liquid, the FIX liquid, and the STB liquid has been described. However, one type may be used, and two types, three types, It may be in any form of five or more.

  (C) In this embodiment, the liquid supply unit 70 supplies the processing liquid to the developing tank at a depth close to the minimum at which the inner end of the film guide groove 412a is immersed in the processing liquid during one rotation of the developing reel 41. Although the case where the developing reel 41 is rotated once has been described, the liquid supply unit 70 supplies the processing liquid to the developing tank to a depth greater than the depth at which the inner end of the film guide groove 412a is immersed in the processing liquid while the developing reel 41 rotates once. 42 may be filled. In this case, since the contact between the emulsion of the film 2 and the processing solution is more reliably performed, the development quality is further stabilized.

  (D) In this embodiment, the case where the film 2 is inserted into the film guide groove 412a with the emulsion surface 2a inside is described. However, the film 2 is inserted into the film guide groove 412a with the emulsion surface 2a outside. But you can. In this case, in order to perform development with an appropriate quality, it is only necessary to form the liquid passage hole 412c in the film guide groove 412a and not to form the liquid passage hole 412c in a position other than the film guide groove 412a. Development is performed.

  (E) In the present embodiment, the case where the guide support bar 412d is formed on the side plate 412 radially from the reel center axis 413 has been described. However, the film guide groove 412a is formed on the guide support bar 412d. The side plate 412 may be formed at a predetermined interval (for example, at equal intervals). When formed at equal intervals, the cross-sectional area of the liquid passage hole 412c (corresponding to a portion where the guide support bar 412d is not formed) becomes substantially constant, so that the development quality is further improved.

  (F) In this embodiment, the case where the liquid supply unit 70 fills the processing liquid into the developing tank 42 and the liquid discharge unit 90 discharges the processing liquid from the developing tank 42 has been described. The liquid may be supplied to the developing reel 41 and the liquid discharging unit 90 may discharge the processing liquid from the developing reel 41. For example, the development reel is formed in a hollow cylindrical shape, and the film held in the guide groove is accommodated in this internal space, and the film insertion slot is configured to be able to be closed so that the inside of the development reel can be switched to a closed space. The liquid supply unit 70 may supply the processing liquid to the closed space, and the liquid discharge unit 90 may discharge the processing liquid from the closed space.
