Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a photographic film automatic developing apparatus capable of developing a 135-size film and a new photographic system (Advanced Photo System: hereinafter referred to as APS) film, and more particularly to a film drawing mechanism of a so-called leaderless type apparatus.
[0002]
[Prior art]
  In an automatic photographic film developing apparatus using a leader that has been used in a conventional development station, a predetermined film provided in a developing process by fixing the leading end of the film to a leader wider than the film width with an adhesive tape or the like. While the reader was transported along the transport path, the film was developed following the reader. Therefore, a film having a width narrower than the leader width can be developed. For example, two 135 size films and two APS films can be developed and developed simultaneously.
[0003]
  On the other hand, with the popularization of APS cameras in recent years, there is a need for a photographic film automatic developing apparatus capable of developing 135 size film and APS film with the same apparatus not only in specialized developing laboratories but also in the stores of DPE dealers. Yes.
[0004]
  In DPE dealers and the like, workers are often unfamiliar with film handling, development processing, etc., and it is required that the apparatus be easy to handle. Therefore, in the conventional photographic film automatic developing apparatus for 135 size film installed in DPE dealers, etc., the process of fixing the leading edge of the film to the reader is omitted, and the film cartridge (made of metal when shipped from the film manufacturer) is omitted. Case: also called patrone), the film is automatically pulled out from the film cartridge, the film end is cut and transported to the development process (as mentioned above, leaderless type) Called).
[0005]
  In the conventional leaderless type photographic film automatic developing apparatus shown in FIG. 10, a film drawing unit 700 for drawing out the film 3 from the film cartridge 1, a developing processing unit 800 for developing the drawn film 3, and a developing process. A development processing line is configured by a drying unit 900 or the like for drying the film.
[0006]
  The film drawer 700 holds the container holder 701 for holding the film cartridge 1 and the leading end of the film 3 drawn out from the film cartridge 1 and draws the film 3 from the film cartridge 1 for development processing. The film conveying roller 702 and the driven roller 703 that are conveyed to the section 800, and a cutter 704 for cutting the end portion of the 135 size film and separating the film 3 from the film cartridge 1 are included.
[0007]
  The development processing unit 800 includes a development processing tank 801 filled with a developing solution, a bleaching processing tank 802 filled with a bleaching solution, fixing processing tanks 803 and 804 filled with a fixing solution, and a stabilizing solution. It consists of stable processing tanks 805, 806, 807 and the like. A film transport path 810 is provided inside each processing tank 801 to 807 and above each processing tank.
[0008]
  The drying unit 900 includes a drying chamber 901 for drying the developed film, a blower 902 for blowing warm air into the drying chamber 901, a conveyance path 903 for conveying the film 3, and the like.
[0009]
  As is apparent from FIG. 10, in the conventional photographic film automatic developing apparatus, the film cartridge 1 is loaded so that the emulsion surface of the film is on the inside, and in each processing solution tank 801-807 of the developing processing unit 800, the emulsion surface Is conveyed outside.
[0010]
[Problems to be solved by the invention]
  In general, since the installation space of the apparatus is limited at a DPE dealer, etc., downsizing of the apparatus is required. Further, from the viewpoint of environmental conservation, it is required to reduce the amount of waste liquid used for development processing as much as possible.
[0011]
  However, as is well known, since the APS film is narrower than the 135 size film, both sides of the APS film cannot be guided by the guide grooves 35 in the development processing line of the 135 size film, and during the development processing step. Cannot be transported along the film transport path. Therefore, if a 135 size film and an APS film are to be developed by a leaderless type photographic film developing apparatus, a dedicated developing processing line is required.
[0012]
  On the other hand, in APS, a film cartridge (a resin case when shipped from a film manufacturer) is used not only for preventing the undeveloped film from being exposed to light but also for storing the film after development. That is, the developed film is stored again in the film cartridge, and the film cartridge cannot be discarded. Therefore, when developing the APS film, conventionally, in the developing station, the APS film is temporarily transferred to a dedicated magazine in a dark room or the like, and the dedicated magazine is loaded into the photographic film automatic developing device.
[0013]
  Therefore, when the 135 size film development processing line and the APS film development processing line are simply arranged in parallel, for example, as shown in FIG. 11, the distance S1 between the center lines L1 and L2 of each development processing line is the film cartridge 1 and the dedicated line. It is limited by the maximum widths D1 and D2 of the magazine 2 and can be narrowed below a certain level. There is substantially no difference from the case where two photographic film automatic developing devices are installed, and the size of the device cannot be reduced. I had a problem to say.
[0014]
  Further, in order to uniformly develop the film, it is necessary to configure the circulated processing solution to directly touch the emulsion surface in each processing solution tank 801-807. However, in the conventional photographic film automatic developing apparatus shown in FIG. 10, since the emulsion surface of the film is transported through the processing solution tanks 801 to 807 of the development processing unit 800, the processing solution circulation path. Therefore, it is necessary to secure a certain distance between the side wall of each processing liquid tank and the film conveyance path. Therefore, it has been impossible to reduce the size of each of the processing liquid tanks 801 to 807 in the direction parallel to the paper surface in FIG.
[0015]
  These problems are derived not only from an increase in the dead space in the photographic film automatic developing apparatus, but also from an increase in the capacity of each processing liquid tank in the developing process, and an increase in the amount of waste liquid.
[0016]
  The present invention has been made in order to solve the above-described problems of the conventional examples. In one photographic film automatic developing apparatus, development processing of a plurality of types of films having different film widths such as 135 size film and APS film is performed. It is an object of the present invention to provide a film drawing mechanism of an automatic photographic film developing apparatus that can reduce the size of the apparatus and reduce the amount of processing solution.

[0037]
  As shown in FIG. 4, in the case of the present embodiment, the first development processing line (center line L1) on the right side is for development processing of 135 size film 3A (an example of the first type film) (hereinafter, development processing). The second development processing line (center line L2) on the left side is for development processing of the APS film 3B (an example of a second type film) (hereinafter referred to as development processing line L2). And
[0038]
  The guide rail 20 is provided in the arrangement direction of the first development processing line L1 and the second development processing line L2 (a direction substantially orthogonal to the film drawing direction). A container holding table 10 for holding the film cartridge 1 (an example of the first film container) or the dedicated magazine 2 (an example of the second film container) is placed on the guide rail 20 in the direction indicated by the arrow H in FIG. The click stop mechanism 11 (see FIG. 5), which is slidable, and is constituted by, for example, a spring and a ball, stops so that its center line is positioned on the center line of each development processing line L1 or L2.
[0039]
  A film detection sensor 107 is provided in the vicinity of the film transport roller 103 in the guide groove 35 of each of the first and second development processing lines L1 and L2. The narrow APS film 3B can be mistakenly inserted into the development processing line L1 for 135 size film. Therefore, two film detection sensors 107 are provided in the first development processing line L1 for 135 size film in order to prevent erroneous insertion. That is, as shown in FIG. 4, only when the 135 size film 3A is correctly inserted, both of the two film detection sensors 107 are turned on at the same time. Therefore, when no film is inserted or when the APS film 3B is inserted. It is possible to distinguish it from the case. Therefore, the controller 500 is configured to drive the film transport roller 103 of the first development processing line L1 for 135 size film only when the two film detection sensors 107 are simultaneously turned on. Further, the first development processing line L1 for 135 size film is provided with an opening 106a for projecting the cutter 106 in order to cut the vicinity of the rear end of the film 3A.
[0040]
  As shown in FIGS. 2, 3, and 7, the turning member 102 includes a first arm 150 a and a second arm 150 b for the first development processing line L <b> 1 and the second development processing line L <b> 2, respectively. The contact levers 150 </ b> A and 150 </ b> B that contact a film container such as the film cartridge 1 or the dedicated magazine 2 are pivotally supported around a shaft 151. A pin 152 is implanted in the second arm 150b of the contact lever 150A for the first development processing line L1 shown in FIGS. 2 and 3 in a direction substantially perpendicular to the paper surface.
[0041]
  As described above, the first development processing line L1 for 135 size film is provided with the cutter 106 for cutting the vicinity of the film end. The cutter 106 is biased in the direction of cutting the film 3 </ b> A by a tension coil spring 153 and is locked by a locking lever 154. The locking lever 154 is pivotally supported around a shaft 155 and is urged in a direction to lock the cutter 106 by a tension coil spring 156 or the like. A transmission lever 157 for transmitting the movement of the contact lever 150A to the lock lever 154 is provided between the contact lever 150A and the lock lever 154. The transmission lever 157 is rotatably supported around a shaft 158 and is urged by a tension coil spring 159 in a direction in contact with the pin 152. Further, the locking lever 154 is provided with an abutting portion 154a such as a pin or a protrusion, and a portion of the transmission lever 157 facing the protrusion 154a (a bent portion 157a) can come into contact with the abutting portion 154a. It is bent.
[0042]
  The swivel member 102 can be moved integrally with the container holding table 10, and the levers 150A and 150B can be shared by the same member. Further, instead of the tension coil springs 156 and 159, a torsion coil spring may be used. Further, the returning operation of the cutter 106 and the charging of the spring 153 are performed in conjunction with the opening / closing operation of the cover member 101 by a link mechanism or the like (not shown).
[0043]
  Next, the operation | movement which cut | disconnects the terminal vicinity vicinity of 135 size film 3A is demonstrated. The film 3 </ b> A pulled out from the film cartridge 1 is transported to the development processing unit 200 (see FIG. 1) by the driving force of the film transport roller 103. In the case of a 135 size film, the end portion of the film 3A is fixed to the spool shaft of the film cartridge 1. Therefore, when all of the film 3A is pulled out from the film cartridge 1, the film cartridge 1 is pulled in the film drawing direction by the driving force of the film transport roller 103 as shown in FIG.
[0044]
  When the film cartridge 1 moves rightward in the figure, the contact lever 150A rotates counterclockwise, and the transmission lever 157 that contacts the pin 152 rotates clockwise. When the transmission lever 157 rotates in the clockwise direction, the bent portion 157a contacts the contact portion 154a of the locking lever 154, and the locking lever 154 rotates in the clockwise direction. When the locking lever 154 rotates more than a predetermined angle, the locking portion 154b of the locking lever 154 moves away from the cutter 106. When the locking by the locking lever 154 is released, the cutter 106 moves upward in the figure by the urging force of the spring 153 and cuts the film 3A. As a result, the film 3A is separated from the film cartridge 1.
[0045]
  On the other hand, a case where a film is stored in the dedicated magazine 2 such as an APS film will be described. As shown in FIG. 9, the dedicated magazine 2 includes a base member 2a and a cover member 2b pivotally supported by the base member 2a. The base member 2a and the cover member 2b have a two-step click stop. . In FIG. 2, (a) shows the fully open state, and (b) shows the closed state in the second stage click stop state. Moreover, (c) shows the half-open state which is a 1st step click stop state. In a normal dark room or the like, the film 3B is transferred from the APS film magazine in the fully opened state shown in (a), and is taken out from the dark room in the closed state shown in (b). In this state, the inside of the dedicated magazine 2 is completely shielded from light. Then, as shown in FIG. 7, the container holding table 10 is loaded with the dedicated magazine 2 closed. In order to bring the dedicated magazine 2 into a half-open state, as shown by arrows A and B in FIG. 9B, the base member 2a and the cover member 2b are urged in opposite directions, and the second-stage click stop is performed. To release.
[0046]
  Note that the film 3B can be pulled out from the dedicated cartridge 2 by forcibly pulling the film 3b even in the closed state shown in FIG. However, the dedicated magazine 2 is used repeatedly, and there is a possibility that the film drawer portion 2c is scratched or dusty. If the magazine 2 is pulled out as it is, the surface of the film 3B may be damaged. Therefore, in order to pull out the film 3B smoothly, the dedicated magazine 2 needs to be in a half-open state. On the other hand, since the film cartridge of 135 size film is normally disposable, even if the film 3A is pulled directly from the film cartridge 1, the surface of the film 3A is hardly damaged.
[0047]
  As shown in FIG. 7, when the dedicated magazine 2 is held between the container holding table 10 and the turning member 102, the first arm 150a of the contact lever 105B contacts the bottom of the base member 2a, and the second arm 150b abuts in the vicinity of the end of the cover member 2b opposite to the shaft fulcrum, and urges in the opposite direction. As a result, the dedicated magazine 2 can be in a half-open state.
[0048]
  In addition to the APS film, the dedicated magazine 2 includes the above-described 135 size film and 126 size film. Since the width of the 126-size film is 35 mm, which is the same as that of the 135-size film, development processing is possible by the development processing line L1 for 135-size film. Accordingly, by making the maximum dimension of each part of the dedicated magazine 2 for each film substantially the same as that of the film magazine 1 for 135 size film, the same container holding table 10 makes it possible to stabilize various film containers. It becomes possible to hold.
[0049]
  As shown in FIG. 5, the right side wall 12 of the container holding table 10 is formed with a groove 12a for engaging and holding a dedicated magazine for 126 size film, for example. Further, as shown in FIG. 6, the left side wall 13 of the container holding table 10 abuts against a part of the film cartridge 1 and is an arm 14 biased by a spring 15 for suppressing the movement of the film cartridge 1. Is provided.
[0050]
  The operation of this embodiment will be described. As shown in FIG. 4, when the 135 size film 3A is developed, the film end processing section 400 cuts a portion where the width at the front end is narrowed in advance to make the width of the film 3A uniform. The container holding table 10 is positioned and stopped by the click stop mechanism 11 so that the center thereof is positioned on the center line of the first development processing line L1 for 135 size film.
[0051]
  Next, with the cover member 101 and the turning member 102 opened, the film cartridge 1 is mounted on the container holding table 10 so that the emulsion surface of the film 3A faces outward. At this time, it is assumed that the leading end portion of the film 3 </ b> A is drawn out in advance by a predetermined length so as to reach the film transport roller 103. At this time, if the curl at the front end of the film 3A (particularly the reverse curl with the emulsion surface facing outward) is tight, the film cartridge tends to rotate due to the elasticity of the film 3. However, since the movement of a part of the film cartridge 1 is restricted by the above-described arm 14, the film cartridge 1 does not rotate, and conversely, the leading end of the film 3A is biased in the direction of extending the curl. .
[0052]
  When the turning member 102 is closed in this state, the leading end portion of the film 3A is sandwiched between the film transport roller 103 and the driven roller 104. Further, when the cover member 101 is closed, the outer cover 101 is locked by the cover lock mechanism 105, and the inside of the cover member 101, that is, the film drawing mechanism 100 is shielded from light. As a result, the film 3A can be pulled out from the film cartridge 1. When it is detected that the cover member 101 is closed by a cover sensor (not shown), the control unit 500 drives the film transport roller 103 to pull out the film 3A from the film cartridge 1, and includes a guide groove, a transport roller 37, and the like. The film is caused to enter the film conveyance path 210.
[0053]
  If the magazine for exclusive use of APS film 2 is loaded in the container holding table 10 by mistake, the width of the APS film 3B is narrower than that of the 135 size film 3A, so that the tip of the APS film 3B has two film detection sensors. One or both of 107 does not cover the detection area of the film detection sensor 107. Therefore, the control unit 500 can determine whether or not the 135 size film 3A is correctly loaded by comparing the outputs of the two film detection sensors 107. When the 135 size film 3A is not correctly loaded, the controller 500 stops driving the film transport roller 103 and generates a warning.
[0054]
  Since the end of the 135 size film 3A is fixed to the spool of the film cartridge 1, when almost all of the film 3A is pulled out from the film cartridge 1, the film 3A is stretched and the film cartridge 1 rotates the contact lever 150A. Let As described above, with the rotation of the contact lever 150A, the transmission lever 157 and the locking lever 154 sequentially rotate to operate the cutter 106 and cut the vicinity of the end portion of the film 3A. When the end of the film 3A passes the detection area of the film detection sensor 107, the output signal from the film detection sensor 107 changes, so that the control unit 500 knows that the entire film 3A has been conveyed to the development processing unit 200.
[0055]
  Since the transport roller 37 and the like are provided at regular intervals in the film transport path 210 of the development processing unit 200, the film 3 </ b> A pulled out from the film cartridge 1 and transported to the development processing unit 200 is transferred to the film transport path 210. Then, the emulsion surface is conveyed in the processing liquid tanks 201 to 207 with the emulsion surface inside, and undergoes development processing. The developed film 3 is conveyed to the drying unit 300, dried, and then discharged outside the apparatus.
[0056]
  When developing the APS film 3B, the vicinity of the end portion of the film 3B pulled out from the dedicated magazine 2 is preliminarily heat-pressed by the film end processing unit 400 and flattened. Further, as shown in FIG. 8, the container holding table 10 is positioned and stopped by the click stop mechanism 11 so that the center thereof is located on the center line of the second development processing line L2 for APS film.
[0057]
  Next, with the outer cover 101 and the inner cover 102 opened, the dedicated cartridge 2 is mounted on the container holding table 10 so that the emulsion surface of the film 3B faces outward. At this time, it is assumed that the leading end portion of the film 3 </ b> B is drawn out in advance by a predetermined length so as to reach the film transport roller 103.
[0058]
  When the inner cover 102 is closed in this state, the leading end of the film 3B is sandwiched between the film transport roller 103 and the driven roller 104 as in the case of the 135 size film 3A. Further, when the outer cover 101 is closed, the outer cover 101 is locked by the cover lock mechanism 105, and the inside of the outer cover 101, that is, the film drawer portion 100 is shielded from light. At the same time, the cover member 2b of the dedicated magazine 2 is opened, so that the film 3B can be pulled out from the dedicated magazine 2. When it is detected that the outer cover 101 is closed by a cover sensor (not shown), the control unit 500 drives the film transport roller 103 to pull out the film 3B from the dedicated magazine 2, and is configured with a guide groove, a transport roller 37, and the like. To enter the film transport path 210. If the 135 size film 3A film cartridge 1 is accidentally loaded into the container holding table 10, the width of the 135 size film 3A is wider than the width of the APS film 3B, so the leading end of the film 3A is inserted into the guide groove 35. Unable to do so, the operator notices an operation error.
[0059]
  Since the tip of the APS film 3B is not fixed to the spool shaft of the dedicated magazine 2, even if all the film 3B is pulled out from the dedicated magazine 2, the film 3B is conveyed to the development processing unit 200 as it is without stretching. When the end of the film 3B passes through the detection region of the film detection sensor 107, the output signal from the film detection sensor 107 changes, so that the control unit 500 knows that the entire film 3B has been conveyed to the development processing unit 200. The following development processing and drying are the same as in the case of the 135 size film 3A.
[0060]
  In the above embodiment, the case where the film cartridge 1 is used as a container for the 135 size film 3A has been described. However, the present invention is not limited to this, and a dedicated cartridge used when the film cartridge 1 is damaged (see FIG. It is the same even if not shown). In addition, although the types of films are exemplified as 135 size film, 126 size film and APS film, the present invention is not limited to this, and the present invention is also applicable to other commercially available film sizes and new film sizes to be developed in the future. It goes without saying that the invention can be adapted.
[0061]
  Further, as a method of cutting the vicinity of the end portion of the 135 size film 3A, the operation of the film cartridge 1 is transmitted to the locking lever 154 by the contact lever 150A and the transmission lever 157, and the locking of the cutter 106 is mechanically released. However, the present invention is not limited to this. For example, the movement of the contact lever 150A is detected by an optical sensor or the like, and the cutter 106 is operated using an electric mechanism such as a motor or an electromagnet. It may be configured.
[0062]
【The invention's effect】
  As described above, according to the film drawing mechanism of the present invention, the container holding table loaded with the film container containing the undeveloped film therein, and the film conveying roller for pulling out the film from the film container and conveying it to the developing processing unit. And a driven roller for sandwiching the leading end portion of the film drawn out from the film container between the film conveying roller, and a pivotable shaft about a predetermined axis so that the driven roller can rotate. And a rotating member that holds the film container with the container holding table in a state in which the emulsion surface of the film is exposed outward, so that the film container to the film are pulled out so that the emulsion surface is on the outside. The emulsion surface of the film transported to the development processing section faces the inside of the film transport path. Therefore, it is not necessary to ensure a circulation path for the processing liquid between the side walls of the processing liquid tanks and the film transport path of the developing unit, and the side walls of the profit tanks and the film transport paths can be brought close to each other. As a result, the capacity of each processing solution tank can be reduced, the dead space in the photographic film automatic developing apparatus can be reduced, and the amount of waste liquid can be reduced.
[0063]
  In addition, the container holding table can be loaded with at least the first and second film containers, and the film stored in the first film container is fixed at the end of the spool of the first film container. Then, the fact that the film has been pulled out to the end and the first film container has moved in the direction of pulling out the film as the film is pulled out is detected by a lever provided rotatably on the swivel member. By unlocking the biased cutter mechanically, or by detecting the rotation of the lever with a sensor and electrically driving the cutter, the film loading operation of a general 135 size film becomes easy. Even workers who are unfamiliar with film handling and development processing at DPE dealers, etc. can perform development processing without failure. It is possible.
[0064]
  Further, the second film container is a magazine composed of a base member and a cover member rotatably supported by the base member, and the lever is held between the container holding table and the swivel member. For example, when the 135 size film cartridge is damaged, or the 135 size film and the film width are formed by contacting the bottom and the vicinity of the end opposite to the shaft fulcrum of the cover member and opening the cover member. It is possible to develop a 126 size film or the like having the same.
[0065]
  Further, the container holding table can be loaded with the first and second film containers corresponding to at least the first type film and the second type film having different widths, respectively, and a direction substantially orthogonal to the film drawing direction. And at least two sets of film transport rollers and driven rollers corresponding to the first type film and the second type film, respectively, with the same photographic film automatic developing apparatus, for example, a 135 size film It is possible to develop two or more types of films having different film widths such as APS films. Furthermore, the width in the direction perpendicular to the film drawing direction of the photographic film automatic developing device can be minimized without being affected by the size of the first film container and the second film container.
[0066]
  Further, the container holding table has a first position and a second position where the center line of the first type film accommodated in the first film container coincides with the center line of the line for developing the first type film. A click stop mechanism is provided so that the center line of the second type film stored in the film container stops at a second position where the center line of the second type film coincides with the center line of the line for developing the second type film. Accordingly, the positioning of the container holding table is facilitated, and even when the first type film and the second type film coexist, the development processing of the film can be performed smoothly.
[0067]
  In addition, at least the first film container and the second film container in the moving direction of the container holding table are made substantially equal to each other so that the first film container and the second film container are stabilized on the container holding table. Can be held.
[0068]
  Further, by providing a fixing member for fixing at least one of the first film container and the second film container on the container holding table, curling of the end portion of the film drawn out from each film container can be achieved. Even in a tight case, it is possible to suppress the movement of the film container due to the elasticity of the film.
