Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an image projection device for projecting an image on a microfilm.

[0002]

Image projection devices are widely used for projecting images recorded on microfilm. This image projection device includes a microfilm reader for enlarging and viewing a microfilm image on a screen,
There are a microfilm reader / printer having a function of copying an image in addition to a function of projecting an image, a microfilm scanner for reading an image of a microfilm by a CCD which is a solid-state image sensor, and the like. There is a type of microfilm in which image information is imprinted on each image frame of a long roll-shaped film. A roll film carrier is provided detachably or integrally incorporated.

In general, since a large amount of microfilm is stored and used, when using the microfilm, a desired image can be quickly searched or copied from the large amount of microfilm. Is required. Recently, in order to satisfy such demands,
Cartridge loaders have been developed for automatically loading and unloading cartridges containing microfilm.

The cartridge loader is attached to an image projecting device such as a reader / printer as an auxiliary device, and has a cartridge housing portion capable of housing a plurality of cartridges. In the cartridge storage part,
An opening for inserting and removing the cartridge to be stored is formed, and a plurality of cartridges are inserted from this opening and stored in the cartridge storage portion. Further, the cartridge storage portion is detachably attached to the cartridge loader body. Such a cartridge storage portion is referred to as a cartridge container or a stacker, and will be referred to as a stacker in the following description.

By the way, the operation of the operator to search or copy a plurality of pieces of image information based on a request from a client (hereinafter referred to as an inquiry operation) is performed as follows. First, the client enters the image search information regarding the desired image information in the search request form for each desired image information and passes it to the operator. The image search information includes a roll number of the cartridge containing the image information, a frame number indicating which frame (the chapter, the number of pages, and the page) of the microfilm the target image information is, the number of copies, and the like. . The operator operates the search information input device connected to the cartridge loader by a key to input all the image search information described in the search request form. Next, the operator takes out each of the cartridges containing the image information to be retrieved from the storage cabinet, stores it in the stacker, and attaches it to the cartridge loader main body. Then, when the operator gives an automatic search instruction, the cartridge loader takes out the cartridges stored in the stacker and loads them into the roll film carrier, and based on the input image search information, the microfilm search and copying are completed. Then, the used cartridge is taken out from the roll film carrier and returned to the stacker. In the cartridge loader, the above operation is automatically and continuously repeated for all the cartridges stored in the stacker.

[0006]

In the case of performing the above automatic search, for example, when the operator stores a wrong cartridge which the client does not instruct in the stacker, the image information matching the image search information is stored in the cartridge. Since it is not included in the accommodated microfilm, the cartridge loader returns the cartridge that is erroneously accommodated, and sequentially performs the loading and ejecting operations for the subsequent cartridges. Therefore, only a smaller number of cases than the number requested by the requester is searched.

Whether or not there is a cartridge mounting error by the operator is of course in the mounting stage,
Even if all the cartridges stored in the stacker set in the cartridge loader are searched, it is still difficult to understand. Therefore, even if there is a case that could not be searched, the operator may report it to the requester without noticing it, and this erroneous report may cause deterioration in the work quality of the inquiry work. Even if an erroneous report is made to the requester, the requester finds out that the operator made a search error by checking the reported contents, but must make a request again, and the inquiry work As a result, the efficiency or simplification of can not be achieved.

If the image information matching the image search information is not included in the microfilm contained in the cartridge, it may be determined that the cartridge is not properly mounted, and the operation of the cartridge loader may be temporarily stopped at that time. However, if this is done, the operator must always be aware of the operating state of the cartridge loader, and it will not be completely free from inquiry work, and it will not be easy to process other work in parallel. I will end up.

[0009] Here, for the purpose of completely automating the micro library, there has been conventionally proposed a system in which a library device capable of accommodating a large amount of micro film is used to make unmanned or labor-saving. This library device is equipped with a memory such as a hard disk, and the memory manages which number of microfilms is stored in which part of the library device, what kind of image information is recorded on each microfilm, etc. is doing. Therefore, whether or not the image information corresponding to the image search information input by the operator exists in the library device is
It suffices to check whether or not the data stored in the memory matches the input image search information. That is, according to the library device, since an operator's input error can be recognized at the input stage, there is an advantage that it does not hinder the subsequent search work and copy work. In addition, since the cartridge is automatically mounted, mounting mistakes are prevented.

However, the cost of the library device is high due to its structure. In addition, many users do not want to be fully automated and want a system that can assist the efficiency or rationalization of work by interposing an operator in the work. Furthermore, although the library device can handle large amounts of microfilm,
The number is not infinite, and it was not an effective device for users with the number of micro assets exceeding the upper limit.

On the other hand, during the operation of the cartridge loader, it was not known what kind of movement the cartridge was performing inside the cartridge loader. This invisible movement of the cartridge allows the operator to
For example, there was anxiety about whether or not the cartridge was certainly loaded in the roll film carrier. Further, when the cartridge is not properly conveyed, the operator cannot easily identify the place where the poor conveyance occurs. It could not be carried out quickly, resulting in a reduction in the work efficiency of the recovery work. Further, it is difficult for the operator to know how many cartridges are waiting for the search and what number of cartridges are currently searched, and it is difficult to decide the subsequent work setup.

[0012] Therefore, a first object of the present invention is to provide an image projection apparatus which can easily recognize an operator's input error, microfilm mounting error, etc. in a search operation.

A second object of the present invention is to provide an image projection apparatus which can easily grasp the movement status of the microfilm.

[0014]

The present invention for achieving the above first object provides an image projection apparatus for projecting an image of a microfilm loaded on a film carrier, comprising:
An accommodating section for accommodating a plurality of microfilms, a loading means for taking out the microfilms from the accommodating section and loading it in the film carrier, and an ejecting means for taking out the microfilms loaded in the film carrier and returning it to the accommodating section. Means, input means for inputting information for designating a microfilm to be projected, and as a result of searching the microfilm based on the information input by the input means, the information input by the input means; An image projection apparatus comprising: a display unit that displays a message when there is a mismatch between the microfilm stored in the storage unit and the microfilm.

Further, according to the present invention for achieving the above second object, in an image projection device for projecting an image of a microfilm loaded in a film carrier, a storage part for storing a plurality of microfilms, and this storage. Section for taking out the microfilm from the unit and loading it in the film carrier, taking out means for taking out the microfilm loaded in the film carrier and returning it to the storing section, inside the storing section, the loading means and the taking out. And a position display unit for displaying the position of the microfilm in the moving path of the microfilm formed by the unit.

[0016]

According to the image projection device of the first aspect, as a result of searching the microfilm on the basis of the information input by the input means, the information input by the input means and the microscopic image stored in the storage section are obtained. When there is a mismatch with the film, the fact is displayed on the display means. For example, if a microfilm that is not a search target is stored in the storage unit, the image that matches the input information will not be included in the microfilm stored in the storage unit. It will be displayed on the means. Therefore, it is possible to recognize a mistake in mounting the microfilm or the like based on the display content.

According to the image projection device of the second aspect,
The position display means displays the position of the microfilm in the moving path of the microfilm formed by the storage means, the loading means and the unloading means. Therefore, even when the microfilm is loaded, taken out, or returned, the position of the microfilm can be visually confirmed and the movement status of the microfilm can be grasped.

The ejection of the cartridge A by the ejection mechanism 23 is performed as follows. When the slider 61 moves to the stop position at the end in the K direction, the torsion coil spring 10
Due to the elastic force of 1, the holder portion 62 faces the M direction. When the base plate 60 is moved to the initial position and the slider 61 is further moved to the stop position at the end in the K direction,
The position of the holder portion 62 facing the M direction corresponds to the position of the supply portion 6 of the roll film carrier 1. In this state, the cartridge A loaded in the supply unit 6
Are held by the upper and lower arms 91 and 92. When the slider 61 moves in the J direction while holding the cartridge A by the holder portion 62, the cartridge A is taken out from the supply 6. When the slider 61 moves to the initial position, the holder portion 62 faces the L direction by the action of the roller 112 and the guide plate 113. The position of the holder portion 62 facing the L direction is determined by the door 26 of the stacker 24.
Corresponds to the position of the return opening that is opened.
It also corresponds to the position of the second window portion 134 (see FIG. 1). The slider 61 is at the initial position, and the base plate 60
Is moved to the stop position at the end in the P direction, the holder portion 62
The cartridge A held at is returned to the rearmost position in the stacker 24 through the second window 134 and the return port. Then, the cartridge A is released from being held by the upper and lower arms 91 and 92. Then, the base plate 60 and the slider 61 return to the initial position.

When the interrupt mode is executed, the interrupt cartridge Ai set in the standby section 132 is set.
Is held by the holder portion 61 of the discharging mechanism 23 and loaded up to the supply portion 6. Further, the cartridge Ai for which the interrupt search or the like has been completed is held by the holder portion 61, taken out from the supply portion 6, and returned to the standby portion 132 again.

In order to detect the position of the slider 61 in the J direction in such an interrupt mode, the sixth sensor 8
6 is provided on the base plate 60. The sixth sensor 86 is
This is a sensor that detects that the slider 61 has moved to the stop position at the end in the J direction located on the left side in FIG. 4 from the initial position. The sixth sensor 86 is the other sensor 81 to 85.
Similarly to, the light emitting element and the light receiving element are included. The sixth sensor 86 is turned on when it is shielded by the projection 87 of the holder portion 61, whereby it is detected that the slider 61 has moved to the stop position at the end in the J direction.

Loading and discharging of the interruption cartridge Ai by the discharging mechanism 23 are performed as follows. In the interrupt mode, when the slider 61 moves to the stop position at the end in the J direction, the roller 112 and the guide plate 11
Due to the action with 3, the holder portion 62 faces the L direction. When the slider 61 is at the end stop position in the J direction and the base plate 60 further moves to the end stop position in the P direction,
The position of the holder portion 62 facing the L direction is the third window portion 135.
This corresponds to the position (see FIG. 1). In this state, the interrupt cartridge Ai set in the standby unit 132
Are held by the upper and lower arms 91 and 92. When the base plate 60 moves to the initial position while holding the cartridge A by the holder portion 62, the cartridge A is taken in from the standby portion 132. By the holder portion 62, the cartridge Ai
When the slider 61 moves to the stop position at the end in the K direction while holding, the holder portion 62 faces the M direction, and the cartridge Ai is loaded in the supply portion 6. The cartridge Ai for which the interrupt search or the like has been completed is taken out from the supply section 6 in the same manner as described above, and when the slider 61 moves to the stop position at the end in the J direction, the holder section 62 holding the cartridge Ai moves in the L direction. It is facing. Slider 61
Is at the stop position at the end in the J direction, and when the base plate 60 further moves to the stop position at the end in the P direction, the cartridge A held in the holder portion 62 passes through the third window portion 135 and enters the standby portion 132. Will be returned. Then, the holding of the cartridge Ai by the upper and lower arms 91 and 92 is released. afterwards,
The base plate 60 and the slider 61 return to the initial position.

When the vertical scan is performed, the roll film carrier 1 moves from the home position (absolute position with respect to the reader / printer body), so that the relative position between the roll film carrier 1 and the cartridge loader 21 is displaced. I will end up. When the cartridge A is loaded or returned, the roll film carrier 1
The relative position between the cartridge loader 21 and the cartridge loader 21 must be a neutral position where the cartridge A can be loaded and returned. The illustrated cartridge loader 21
The loading mechanism 22 and the stacker 24 in FIG.
The roll film carrier 1 via the mounting plate 115 or the like.
Therefore, the relative positions of the loading mechanism 22 and the stacker 24 with respect to the roll film carrier 1 do not shift even when a vertical scan is performed. However, since the ejection mechanism 23 in the cartridge loader 21 does not move in conjunction with the roll film carrier 1, the relative position with respect to the roll film carrier 1 is displaced when the vertical scan is performed. Therefore, in the present embodiment, as described below, the roll film carrier 1 is left at the position after the vertical scan, and the roll film carrier 1 is moved by the base plate 60 side of the discharge mechanism 23, so that the roll film carrier 1 is moved. 1 and the discharging mechanism 23 of the cartridge loader 21 are moved to the neutral position.

As shown in FIG. 4, when the roll film carrier 1 and the discharging mechanism 23 are in the neutral position, the third and fourth sensors 83, 84 are provided by the light shielding plate 89 fixed to the roll film carrier 1. It is shielded from light and turned on. The direction in which the vertical scan was performed is
It is detected based on the states of the third and fourth sensors 83, 84. That is, when the third sensor 83 is turned on while being shielded by the light shielding plate 89 and the fourth sensor 84 is turned off without being shielded, it is detected that the vertical scanning direction is the front side. Conversely, the third sensor 83
Is off and the fourth sensor 84 is on, the vertical scanning direction is detected to be the depth side. When it is detected that the vertical scanning direction is on the front side, the fourth motor 75 is driven to rotate forward, for example, and the base plate 60 is moved toward the front side until the fourth sensor 84 is turned on. The carrier 1 and the ejection mechanism 23 move to the neutral position. Similarly, when the vertical scanning direction is detected to be on the depth side, the base plate 60 is moved toward the depth side until the third sensor 83 is turned on, whereby both 1 and 23 are moved to the neutral position. .

The neutral positions of the roll film carrier 1 and the cartridge loader 21 are different in absolute position with respect to the reader / printer main body depending on whether the roll film carrier 1 is at the home position or when it is corrected after the vertical scan. It will be. However, if the roll film carrier 1 and the cartridge loader 21 are in a relative neutral position, the cartridge loader 21 can perform a predetermined loading / unloading operation, so there is no problem even if the absolute positions with respect to the reader / printer main body are different. . Further, in order to detect the vertical scanning direction, it is necessary that one of the third sensor 83 and the fourth sensor 84 is shielded by the light shielding plate 89 and remains on. Therefore, the distance between the third sensor 83 and the fourth sensor 84, the width dimension of the light shielding plate 89, and the like are set in correspondence with the maximum distance that the roll film carrier 1 can move by the vertical scan.

In the cartridge loader 21 configured as described above, the original orientation of the cartridge A stored in the stacker 24 before being taken out by the loading mechanism 22 and the cartridge after being returned to the stacker 24 by the discharging mechanism 23. The direction of A is different. FIG. 11 is a perspective view showing a state where the reel 4 is taken out from the cartridge A, and shows an ANSI standard type cartridge. The present embodiment is not limited to this type of cartridge, but can be applied to, for example, a 3M type cartridge by appropriately modifying the shapes of the upper and lower arms 91 and 92. When each cartridge A is initially stored in the stacker 24, each cartridge A is
The back label side 122 faces the front side shown in FIG. 3, and the opening side 123 faces the supply section 6 side of the roll film carrier 1 and is housed in the stacker 24. The cartridge A returned to the stacker 24 is
The sheets are stored in the stacker 24 in the reverse state, that is, with the back label side 122 facing the supply section 6 side and the opening side 123 facing the front side. When performing an interrupt search,
The interrupt cartridge Ai is set in the standby portion 132 with the back label side 122 facing the third window 135 side and the opening side 123 facing the front side. The orientation of the cartridge Ai when the interrupt search or the like is completed and returned to the standby unit 132 again is the same as when the cartridge Ai was initially set in the standby unit 132.

The direction of the cartridge A in the stacker 24 is reversed because the cartridge A is moved and returned as follows. That is, the used cartridge A is held from the spine label side 122 and rotated from the M direction to the L direction by the upper and lower arms 91 and 92 of the holder portion 62 of the ejecting mechanism 23, and the used spine label side 122 is directly held. This is because the rear side is moved to the inside of the stacker 24 with the opening side 123 facing the front side and returned.

In the cartridge loader 21, a loading path B for newly loading the cartridge A by the loading mechanism 22 and an ejection path C for ejecting the used cartridge A by the ejection mechanism 23 are individually formed. (See FIGS. 3 and 4). In this way, stacker 2
The loading path B from 4 to the supply section 6 of the roll film carrier 1 and the discharge path C from the supply section 6 to the stacker 24 follow different paths without overlapping. There is.

The cartridge loader 21 has three operation modes, that is, "auto mode", "semi-auto mode" and "interrupt mode", which can be selectively used according to the search method and application. There is. The auto mode is a mode in which each of the cartridges A stored in the stacker 24 is sequentially and continuously loaded and discharged. The semi-auto mode is a mode in which the cartridge A stored in the stacker 24 is intermittently loaded and discharged in response to an instruction from the operator. The interrupt mode is a mode in which one cartridge is loaded and ejected.

Since the operator designates the above three operation modes of the cartridge loader 21, as shown in FIG. 12, the display panel 137 has a function of an auto mode key for setting the auto mode and a semi auto mode for setting the semi auto mode. An auto / semi-auto selection key 140 having the function of a mode key is provided. Each time the auto / semi-auto selection key 140 is pressed, the auto mode and the semi-auto mode are alternately selected and set. Also, an interrupt key 141 for setting the interrupt mode is provided. Further, a select key 142 for selecting replacement of the cartridge A or loading of the microfilm F in the cartridge A is provided. If the operator presses the right side of the select key 142, the cartridge A
Is exchanged, and if the left side is pressed, the microfilm F is loaded. As the display section that displays the selected mode, L that lights up when the auto mode is selected

Move until turned on. The number of the cartridges A stored in the cartridge container 24 can be easily recognized by measuring the moving amount of the moving claw portion 31 by the CPU or the counter. For example, when N cartridges A having the maximum capacity are stored in the stacker 24, the initial movement amount of the set rod 33 is, for example, Rmm, and the width of one cartridge A is, for example, 25.4 mm. Then, the number of cartridges is recognized as follows. For example, the initial movement amount of the set rod 33 is Rmm plus 25.
If it is 4 mm, the number of the cartridges A stored in the stacker 24 is recognized as "N-1". Further, if the initial movement amount of the set rod 33 is Rmm plus (25.4 mm × 2), the number of the cartridges A stored in the cartridge container 24 is recognized as “N−2”. Then, based on the recognized number of cartridges A, the microfilm MC determines that the number of replacements required to replace all the cartridges A is the number of cartridges A minus one.

Next, the operation of this embodiment will be described. The roll film carrier 1 can automatically search for image information based on search information such as a blip or an IMC (image management code) attached to the microfilm F. When performing automatic search processing of image information, the operator needs image search information relating to image information to be searched or copied. The image search information includes (1) the roll number of the cartridge A containing the image information to be searched or copied, and (2) the microfilm F contained in the cartridge A in which the target image information is input in (1) above. There is a frame number indicating which frame (what chapter, what number, page) of (3) the number of copies and a copy command when copying the target image information. The operator can directly input the image search information by operating the operation panel 136 or a key on the keyboard.

The basic flow of the image projection system according to this embodiment is as shown in FIG. 16, and when the image search information is obtained by the key input of the operator (S200), this image search information is searched on the display 163. It is displayed as a list or is printed out from the printer 164 (S201). Based on the search list displayed or printed out, the operator selects the cartridge A
From the storage rack and put it in the stacker 24 (S
202), the stacker 2 which has finished storing the cartridge A
4 is set at a predetermined position of the cartridge loader 21 (S203). Start switch 16 by operator
When 0 is pressed, the automatic search process starts and the stacker 24
The image information corresponding to the image search information is automatically searched and copied from the microfilm F contained in the cartridge A therein (S204).

When the operator stores the wrong cartridge A in the stacker 24, the image information corresponding to the image search information cannot be searched. However, even when such a search error occurs, the image projection system cannot Without stopping the operation, the wrong cartridge A is returned to the stacker 24 and the automatic search process for other cartridges A is continued. Even when the correct cartridge A that matches the image search information is stored, for example, IMC
The roll number of the cartridge A may not be known due to a reading error or the like, and the image information corresponding to the image search information may not be retrieved. Even in this case, the image projection system does not stop the operation, returns the cartridge to the stacker 24 without being searched, and continues the automatic search process for other cartridges. If there is such an unsearched or missed search cartridge A, that is, if there is a mismatch between the input image search information and the microfilm F in the stacker 24, the search result information indicating that is found. Input to computer PC, display 163
This is displayed as described later.

When the automatic search process is completed, the operator confirms whether or not there is any unsearched or search-missed cartridge A by the contents displayed on the display 163 (S205). If there is an unsearched or missed search cartridge A, insert the correct cartridge A into the stacker 24 or insert the unsearched cartridge A again (S
207), the start switch 160 is pressed to perform automatic search processing. Even if there is no search, re-search can be executed only by pressing the start switch 160, so that erroneous input accompanying re-input of image search information can be prevented.

As an example of obtaining the image search information in step S200, in addition to the operator directly inputting the image search information from the operation panel 136 or the keyboard, FIG.
As shown in (1), the image search information can be obtained by searching a database stored in the computer PC. As shown in (2) of the figure, the facsimile device 165 is connected to the computer PC. The facsimile device 165 can also receive and obtain image search information. In addition, as shown in FIG.
It is also possible to obtain image search information by downloading data from the host computer 166 connected to the computer, as shown in (4) in FIG. You can also get

At the time when the automatic search process is started, all of the obtained image search information is displayed on the display 163 as a search list. When the automatic search process is continued and the image information corresponding to the obtained image search information is searched and copied, the image search information is deleted from the displayed search list. Therefore, if there is an unsearched or missed search cartridge A, only the unsearched image search information is displayed on the display 163 as a list. An example of the display example before the search and the display example after the search is shown below. This example shows that the image information of the frame number 0015 in the microfilm F accommodated in the roll number 1023 was not retrieved.

It should be noted that all of the image search information is always displayed as a list on the display 163 from the start to the end of the search process, but the image search information that has been searched and the image search information that has not been searched or has been missed are displayed. By changing the color, it may be possible to display that there is a mismatch between the input image search information and the microfilm F in the stacker 24. The display of such inconsistency may be performed on the operation panel 136.

FIG. 14 shows an embodiment for recognizing a non-search or a search error. A digital reader capable of electrically reading image information recorded on the microfilm F with a CCD element or the like. / Printer 168
Is a SCSI cable 17 that can transmit image data at high speed.
It is connected to the computer PC via 0. Also,
The operation panel 136 and the computer PC are RS232C
It is connected via a cable 169. The microfilm F in this embodiment uses a film of the type in which the frame number of each image frame, that is, the frame number is imprinted together with the image information, and the computer PC uses the image data existing on the inputted image. An OCR is provided for converting a certain frame number into code information. In this embodiment, when the blip or the like is counted based on the image search information and the target image frame is detected in the roll film carrier 1, the detection result is returned to the computer PC via the cable 169 (Stat).
us). After the computer PC reads the status, the image information recorded in the image frame is recorded in the cable 17
It is input to the computer PC via 0. Next, the OCR reads the frame number on the input image and converts it into code information. Then, the computer PC collates the converted code information with the image search information that is the basis of the image frame detection, and if there is an error, determines that the image search information is unsearched or missed search image information. As described above, the display 163 displays that there is a mismatch between the input image search information and the microfilm F in the stacker 24. With such a configuration, the reliability of search is significantly improved.

The automatic search process in step S204 is as follows.
This is performed based on the flow shown in FIG. When the automatic search process is started, an initialization routine for setting each member of the cartridge loader 21 to the initial position or the like is executed (S210). In step S211, the cartridge increase / decrease prohibition process is executed, and the prohibition lever 54 moves the stacker 24.
When the cartridge loader 21 is in operation, the cartridge A stored in the stacker 24 is prevented from being extracted or a new cartridge A being added. In step S212, the cartridge loading routine is executed, the first cartridge A is loaded in the supply unit 6 of the roll film carrier 1, and the microfilm F accommodated in this cartridge A is loaded. Further, the movable claw portion 31 stands by at a predetermined position in the stacker 24, so that the stacker 24 is prevented from being removed. After incrementing the variable C for counting the number of retrieved cartridges by 1 (S213), the roll film carrier 1 reads the IMC attached to the microfilm F (S214), and the cartridge A containing the microfilm F is read. Recognize the roll number, blip mark type, etc. Instead of reading the IMC, the barcode attached to the cartridge A may be read to determine the contained microfilm. The next cartridge A is set on the set bar 33 while the loading of the microfilm F is completed and the search or the like is performed.

In step S215, it is determined whether the recognized roll number matches the unsearched cartridge A number. If they match, the roll film carrier 1 conveys the microfilm F and automatically searches for the desired image information based on the blip attached to the microfilm F and the frame number of the image search information. (S216). When the image information that matches the frame number of the image search information is searched (S217), print processing or scanning processing for reading the image information as an electric signal is performed (S218). Further, when a plurality of target frames are present in the loaded microfilm F, other image frames are automatically searched in sequence (S216 to S218).

When all the search and copying of the target image information regarding the microfilm F accommodated in the currently loaded cartridge A are completed, in step S222, all the cartridges A accommodated in the stacker 24 are searched. It is determined based on the calculated number of required replacements whether or not the above has been completed. If the search or the like has not been completed for all the cartridges A, the cartridge exchange routine is executed (S223), the cartridge A loaded in the supply unit 6 of the roll film carrier 1 is discharged, and the next new cartridge A is loaded. Loading is done in parallel at about the same time. In the roll film carrier 1, after the variable C is incremented, the IMC attached to the newly loaded microfilm F is added.
Is read (S214), and the operations from step S215 to step S219 are repeated.

During such a retrieval process, if the loaded cartridge A does not match the unretrieved cartridge A (S215) and if the image information is not retrieved (S217), an error occurs. The content of the variable C is set to the variable Nx indicating the generated cartridge number (S220), and the variable X for counting the number of errors is incremented by 1 (S221).

When it is determined that the search or the like has been completed for all the cartridges A based on the number of exchanges calculated in advance (S222), the discharge routine is executed (S224),
With respect to the cartridge A that has been loaded and searched for lastly, the roll film carrier 1 is discharged from the supply unit 6 and returned to the stacker 24. Further, the moving claw portion 31 is moved to the initial position, the prohibition of the removal of the stacker 24 is released, and the prohibiting lever 54 moves the stacker 2 into the stacker 2.
4 is moved to a position retracted from the opening 24a of No. 4 and the prohibition of increase / decrease of the cartridge A is released.

Then, the value of the variable Nx set in step S220, that is, the number of the cartridge in which the error occurred and the unsearched data are displayed on the display 163 (S2).
25, S226), the automatic search process is completed. The number of the cartridge in which the error has occurred may be displayed on the display 163 when the error occurs.

An example of the basic flow of the inquiry work is shown in FIG. 18. The operator who receives the search request form from the client operates the keyboard to operate the computer PC.
The database stored in the database is searched to obtain image search information regarding the image information described in the search request form (S
230, S231). This image search information is displayed on the display 163 as a search list (S232) or is printed out from the printer 164 (S23).
3). The operator collates the displayed or printed output search list with the request contents, and proceeds to step S23.
Check if the operation in 1 was correct.
Next, the operator takes out the cartridge A from the storage rack and inserts it in the stacker 24 while looking at the printed search list (S234). Then, the operator sets the stacker 24, in which the storage of the cartridge A is completed, to the predetermined position of the cartridge loader 21, and presses the start switch 160 (S235). As a result, the automatic search process is started, and at this time, the operator is temporarily released from the inquiry work and can perform other work.

During the automatic search process, the image information corresponding to the image search information is automatically searched and copied from the microfilm F contained in the cartridge A in the stacker 24, and the image search information and the stacker are also copied. When a mismatch with the microfilm F in 24 occurs, the fact is displayed on the display 163.

The operator looks at the time when the cartridge A in the stacker 24 has completed one cycle, looks at the search result displayed on the display 163 (S236), and determines whether there is a cartridge A that has not been searched or has missed a search. Yes (S237). If there is a cartridge A that has not been searched, the operator checks the display contents to see if there is a mistake in mounting the cartridge A, and if the wrong cartridge A is stored, the correct cartridge A is stacked. 24, and if there is no mounting error of the cartridge A, the unsearched cartridge A is inserted again (S238). At this time, the cartridge A that has been normally searched is taken out from the stacker 24. Then, if the start switch 160 is pressed again to perform the automatic search process, the target image information is searched based on the unsearched image search information.

Cartridge A stored in the stacker 24
If there is no unsearched for, the operator sets the next stacker 24, if there is one, in the cartridge loader 21 (S239), and repeats the operations of steps S235 to S238 described above. When the requested search is completed, the operator reports the result to the requester and ends the inquiry work.

In this way, the input image search information,
If there is a discrepancy between the microfilm stored in the stacker 24 and the display, the display 16
3 is displayed, the operator can easily grasp the search status. That is, the operator can easily recognize an input error, a microfilm mounting error, etc. before reporting to the client. Therefore, the operator does not notice that there is a case that could not be searched and does not report to the requester, and the quality of the search operation can be improved. Further, since there is no erroneous report, the requester does not have to re-request, and the efficiency and simplification of the inquiry work can be achieved. Further, when the automatic search is started, the operator is temporarily released from the inquiry work, so that the operator can easily process other works in parallel. Moreover, it is possible to provide a system that is cheaper than an expensive library device and that can assist the efficiency or rationalization of the work by intervening the operator in the work. Further, the system is effective even for a user having a number of micro assets exceeding the maximum number that can be handled by the library device.

Next, the initialization performed by the cartridge loader 21, the increase / decrease prohibition process of the cartridge A, the loading of the cartridge A, the searching operation, the replacement of the cartridge A,
19 to 2 for each operation of ejecting the cartridge A
This will be described with reference to the flowchart shown in FIG.

Initialization As shown in FIG. 19, in this initialization routine, a process of initializing each member of the cartridge loader 21 is performed. First, in step S10, the second switch 42
Is ON, that is, whether or not the carrier front surface portion 38 of the roll film carrier 1 is rotated to the closed position along the H direction which is the initial position. Step S1
If the determination of 0 is NO, the second motor 41 is driven to rotate normally (S11), and it is determined that the second switch 42 is turned on and the carrier front face portion 38 is rotated to the closed position (S11).
10), the second motor 41 is stopped (S12). In the next step S13, whether or not the third switch 50 is on, that is, the moving claw portion 31 of the loading mechanism 22 is at the initial position D
It is determined whether or not it is located at the end of the direction. Step S1
If the determination of No. 3 is NO, the first motor 36 is driven in reverse rotation (S14), the third switch 50 is turned on, and it is determined that the moving claw portion 31 has moved to the initial position (S1).
3), the first motor 36 stops (S15). In step S16, it is determined whether the first sensor 81 is on, that is, whether the slider 61 is located at the initial position.
If the determination in step S16 is NO, the third motor 70 is driven to rotate normally (S17), and it is determined that the first sensor 81 is turned on and the slider 61 has moved to the initial position (S16). 70 stops (S18). When the slider 61 is in the initial position, the holder portion 62 faces the L direction. In step S19, whether or not the third sensor 83 and the fourth sensor 84 are on, that is, the base plate 6
It is determined whether 0 is located at the initial position (neutral position with respect to the roll film carrier 1). If the determination in step S19 is NO, the third and fourth sensors 8
Based on the ON / OFF states of Nos. 3 and 84, the deviation direction of the relative position between the roll film carrier 1 and the base plate 60 is detected as described above. When it is determined that the fourth motor 75 is appropriately rotationally driven in the normal and reverse directions according to the displacement direction (S20), the third and fourth sensors 83 and 84 are turned on, and the base plate 60 is moved to the initial position (S19). ), The 4th motor 75 stops (S21). Further, in step S22, the keep solenoid 106 is turned off, and the upper and lower arms 91, 92 of the holder portion 62 are rotated in the opening direction by the elastic force of the tension coil springs 97, 98. Thus, in the initial setting routine, the carrier front surface portion 38 and the moving claw portion 3 are
1, slider 61, base plate 60, upper and lower arms 91, 92
Are set to the initial position and the initial direction, respectively.

Increment / Inhibition Prohibition Processing for Cartridge A As shown in FIG. 20, in the cartridge increase / decrease inhibition routine, the inhibition lever 54 is moved. Step S
23, it is determined that the start switch 160 is turned on. In step S24, the solenoid 51 is turned on. As a result, the prohibiting lever 54 rotates about the support shaft 53 against the elastic force of the tension coil spring 55 and projects to a position where it covers the opening 24 a of the stacker 24. By moving the prohibiting lever 54 to this position, the stacker 2 can be operated while the cartridge loader 21 is operating.
It is prevented that the cartridge A housed in the cartridge 4 is pulled out or a new cartridge A is added.

Loading of Cartridge A As shown in FIGS. 21 and 22, in this cartridge loading routine, the first cartridge A is loaded by the loading mechanism 22.
1, etc. are loaded. In step S25, the moving claw portion 31 moves in the E direction from the initial position by the normal rotation driving of the first motor 36. The moving amount Smm of the moving claw portion 31 is CP of the microcomputer MC.
It is measured by U or a counter and temporarily stored in RAM (S26). With the movement of the moving claw portion 31,
The group of cartridges A in the stacker 24 also moves in the E direction, and the first cartridge A1 is set by the set rod 3
When set to 3, the first switch 37 is turned on (S
27). The number of cartridges A stored in the stacker 24 is recognized based on the amount of movement of the moving claw portion 31 at this time (S28), and the number of exchanges required to exchange all the stored cartridges A is determined. . When it is recognized that 10 cartridges A are stored, L
ED ₁ to LED ₁₀ are turned on (S29).

When the first switch 37 is turned on, the first motor 36 reverses and is driven by reverse rotation, and the moving claw portion 31 reverses and moves in the D direction (S30). The moving claw portion 31 does not return to the initial position, that is, the position where the third switch 50 is turned on, but when returning to a predetermined position in the stacker 24 before the third switch 50, the first motor 36 is stopped and The movement is stopped (S30 to S32). Hereinafter, the predetermined position in the stacker 24 where the moving claw portion 31 stops will be referred to as a stacker stop position. The distance from the initial position of the moving claw portion 31 to the stop position inside the stacker is predetermined. The stacker 24 is controlled by controlling the number of drive pulses input to the first motor 36, which is a stepping motor.
Even if the number of the cartridges A accommodated in is different, the moving claw portion 31 is stopped at the stacker stop position. When the moving claw portion 31 stands by inside the stacker 24, the engaging portions 31a and 31b of the moving claw portion 31 become freely engageable with the bottom wall of the stacker 24, whereby the cartridge loader 21
It is prevented that the stacker 24 itself is removed during the operation of. The stop position in the stacker where the moving claw portion 31 stops in the stacker 24 is the stacker 24 of the cartridge A.
It is a position where it does not interfere with the return operation to.

Then, in step S33, the carrier front surface portion 38 is moved from the closed position, which is the initial position, to the 9th position by driving the second motor 41 in the reverse rotation direction.
It is rotated forward by 0 degrees and is in the open position along the I direction. By rotating the carrier front face portion 38 to the open position, the lock of the set rod 33 in which the cartridge A1 is set is released, and the stacker 24 is released.
From the side toward the front surface 38 of the carrier. As a result, the cartridge A1 is held by the carrier front surface portion 38 (S34). Here, the carrier front part 3
When the fourth switch 154 does not turn on even when the switch 8 is rotated to the open position (S35), the carrier front portion 3
8, it is determined that a holding error of the cartridge A1 has occurred, the LED ₁ is turned off, the LED ₁₃ is blinked,
The operation of the cartridge loader 21 is forcibly stopped (S35, S37). When the fourth switch 154 is turned on, since the cartridge A1 is held by the carrier front surface portion 38, the LED ₁ is turned off and the LED ₁₃ is turned on (S36).

Thereafter, the second motor 41 is driven to rotate in the normal direction, and the carrier front surface portion 38 rotates in the H direction while holding the cartridge A1 (S38). When the second switch 42 is turned on due to this rotation, the second motor 4
1 stops (S39, S40). As a result, the cartridge A1 is positioned and loaded in the supply unit 6 of the roll film carrier 1. Here, when the second motor 41 has rotated by a certain number of pulses but the second switch 42 has not been turned on (S39), it is determined that a rotation error of the carrier front surface portion 38 has occurred, the LED ₁₃ is turned off, and L is turned off.
The ED ₁₄ blinks and the operation of the cartridge loader 21 is forcibly stopped (S41, S42). When the second switch 42 is turned on, the cartridge A1 is in the supply unit 6
LED ₁₃ is turned off because it is loaded into
₁₄ is turned on (S43).

With the rotation of the carrier front face portion 38, the set rod 33 moves to the cartridge container 24 side and is locked again. Then, in the next step S44, the microfilm F contained in the first cartridge A1 loaded in the supply unit 6 is loaded from the rewinding reel 4 toward the winding reel 5.

When the loading of the microfilm F is completed, the slider portion 61 at the initial position moves in the K direction by a certain distance to a predetermined position in front of the second sensor 82 (S45). The predetermined position before the second sensor 82 at which the slider 61 stops is hereinafter referred to as the second sensor front stop position. At the second sensor front stop position, the holder portion 62 is held in a state of facing the M direction by the elastic force of the torsion coil spring 101. The distance from the initial position of the slider 61 to the stop position in front of the second sensor is predetermined, and by controlling the number of drive pulses input to the third motor 70, which is a stepping motor, the slider portion 61 moves in front of the second sensor. It is stopped at the stop position. At the second sensor front stop position where the slider 61 stops before the second sensor 82, when the vertical scan is performed, the upper and lower arms 91, 92, etc., which face the M direction, are located at the supply section of the roll film carrier 1. It is a position where it does not interfere with the cartridge A loaded in the cartridge 6. In this way, in the cartridge loading routine, the moving claw portion 31 is reciprocated from the initial position, the first cartridge A1 is loaded in the supply portion 6, and the microfilm F accommodated in this cartridge A1 is loaded. Further, the movable claw portion 31 stands by inside the stacker 24, which prevents the stacker 24 itself from being removed.

Searching Operation As shown in FIG. 23, in this searching routine, the cartridge A to be searched next is set on the set rod 33. In the roll film carrier 1, for the cartridge A loaded in the supply unit 6, while the microfilm F is being conveyed between the rewinding reel 4 and the winding reel 5, desired image information is manually searched or It is automatically searched.

While the roll film carrier 1 is being searched, in the cartridge loader 21, in step S50, the first motor 36 is driven to rotate normally, so that the moving claw portion 31 of the loading mechanism 22 becomes E. Moved in the direction. At this time, the moving amount of the moving claw portion 31 is equal to the width 2 of one cartridge A in addition to the first moving amount Smm counted and stored in step S26 described above.
It is a length obtained by adding 5.4 mm and minus the distance from the initial position of the moving claw portion 31 to the stop position inside the stacker. When the first switch 37 is turned on by the movement of the moving claw portion 31 (S51), the cartridge A2 to be loaded next is set on the set rod 33, so that the LED ₁ is turned on and is being turned on. Was the LED
₁₀ is turned off.

When the moving claw portion 31 moves in the E direction by the predetermined distance, the first motor 36 immediately reverses and is driven in reverse rotation, and the moving claw portion 31 reverses and moves in the D direction. Yes (S53). The moving claw portion 31 has a step S
Similar to 30 to S32, it does not return to the initial position but returns to the stop position within the stacker, the first motor 36 is stopped and its movement is stopped (S53 to S55). Moving claw part 31
By waiting inside the stacker 24, the stacker 24 itself is prevented from being removed.

By the operation of the moving claw portion 31 returning to the stop position in the stacker, the cartridge A2 set on the set bar 33 remains sandwiched between the moving claw portion 31 and the first switch 37 and the like. Is prevented. As a result, the cartridge A2 is smoothly inserted into the carrier front surface portion 38. Further, even when the first cartridge A1 is set, the return movement operation of the moving claw portion 31 prevents the cartridge A1 from being sandwiched. The moving speed of the moving claw portion 31 is set to be higher than the moving speed when the first cartridge A1 is set when the second cartridge A2 and subsequent cartridges A are set. As described above, in the searching routine, the moving claw portion 31 of the loading mechanism 22 is reciprocally moved from the stop position in the stacker while searching the microfilm F, and the next cartridge A
Are set on the set rod 33. Further, the stacker 24 itself is prevented from being removed.

Replacement of Cartridge A As shown in FIGS. 24 to 27, in the cartridge replacement routine, the ejection of the cartridge A1 loaded in the supply section 6 of the roll film carrier 1 and the loading of the next new cartridge A2 are performed. , But almost simultaneously in parallel. The cartridge exchange routine is sequentially repeated until the final cartridge An is loaded. In the following description of this routine, the cartridge A1 ejection operation and the cartridge A2 loading operation will be described.

When the search for the microfilm F in the cartridge A1 loaded in the supply unit 6 is completed and a rewind signal is output (S60), the motor connected to the rewinding reel 4 is rotationally driven. Yes (S6
1) The rewinding of the microfilm F is started. When the drive shaft is reset (S62), the driving of the motor is stopped (S63). As a result, the microfilm F is completely rewound on the rewinding reel 4, and the process proceeds to step S69.

When the rewind signal is output, the processes of steps S64 to S68 are performed in parallel with the rewind of the microfilm F (S61 to S63). First, it is determined whether the vertical scan has been executed based on the on / off states of the third and fourth sensors 83 and 84 (S64). That is, the third and fourth sensors 8
It is determined that the vertical scan is not executed if one of the three and 84 is in the off state, and the vertical scan is not executed when both of them are in the on state. When the vertical scan is performed, the vertical scan direction is detected based on the states of the third and fourth sensors 83 and 84 (S65). When the third sensor 83 is on and the fourth sensor 84 is off, it is detected that the vertical scan direction is the front side, and
When the sensor 83 is off and the fourth sensor 84 is on,
The vertical scan direction is detected to be on the depth side. Next, in step S66, the fourth motor 75 is appropriately rotated in the forward and reverse directions based on the detected vertical scan direction. When the vertical scan direction is on the front side, the fourth motor 75 is driven to rotate normally,
The base plate 60 moves toward the front side. When the vertical scan direction is on the depth side, the fourth motor 75 is reversely driven and the base plate 60 moves toward the depth side. In step S67, it is determined whether the base plate 60 and the roll film carrier 1 have moved to the neutral position, based on the states of the third and fourth sensors 83, 84. For example, when the vertical scan direction is on the front side, the base plate 6 is turned on when the fourth sensor 84 is turned on.
0 and the roll film carrier 1 are determined to have moved to the neutral position, and the fourth motor 75 is stopped (S
68).

In step S69, the third motor 70
Is reversely driven, and the slider 61 moves in the K direction from the second sensor front stop position. When the second sensor 82 is turned on and it is detected that the slider 61 has moved to the stop position at the end in the K direction, the third motor 70 is stopped,
The slider 61 stops its movement (S70, S7).

D ₁₅ is flashing, the operation of the cartridge loader 21 is forcibly stopped (S90). When the first sensor 81 is turned on with the fifth switch 155 kept on (S91),
It is detected that the slider 61 has moved to the initial position,
The third motor 70 is stopped and the slider 61 stops its movement (S92). Here, when the third motor 70 rotates by a certain number of pulses but the first sensor 81 does not turn on (S91), it is determined that a movement error of the slider 61 has occurred, the LED ₁₅ is turned off, and the LED ₁₆ blinks. Then, the operation of the cartridge loader 21 is forcibly stopped (S93, S94). When the first sensor 81 is turned on, since the slider 61 has been moved to the initial position, the LED ₁₅ is turned off and the LED ₁₆ is turned on (S95). Further, when the slider 61 moves to the initial position, the holder portion 62 faces the L direction while holding the cartridge A1 by the action of the roller 112 and the guide plate 113.

Next, the processing of steps S76 to S87 will be described. The front surface 38 of the carrier from which the cartridge A1 is taken out is rotated 90 degrees in the I direction from the closed position to the open position (S76), the lock of the set rod 33 is released, and the next new cartridge A2 is transferred to the front surface 38 of the carrier. Held in. The carrier front surface portion 38 which holds the cartridge A2 and is located at the open position rotates in the H direction while holding the cartridge A2 in steps S81 to S83. As a result, the cartridge A2
The roll film carrier 1 is positioned and loaded in the supply unit 6. At the same time, the set rod 33 moves to the cartridge container 24 side and is locked again. Then, the newly loaded microfilm F in the cartridge A2 is loaded (S87). Even when the cartridge A2 is being loaded, the fourth

When the fifth switch 155 is turned off during the movement (S98), it is determined that the cartridge A1 has fallen off during the movement of the base plate 60, the LED ₁₇ blinks, and the operation of the cartridge loader 21 is forced. Is stopped (S99). When the fifth sensor 85 is turned on while the fifth switch 155 is still on (S100), the base plate 6
It is detected that 0 has moved to the stop position at the end in the P direction, the fourth motor 75 is stopped, and the base plate 60 stops its movement (S101). Here, when the fourth motor 75 rotates by a certain number of pulses but the fifth sensor 85 does not turn on (S100), it is determined that a movement error of the base plate 60 has occurred, the LED ₁₇ blinks, and the cartridge loader 21. Is forcibly stopped (S102, S1
03). When the fifth sensor 85 is turned on, the base plate 60 is set to P
Has been moved to the stop position at the end in the direction, and this movement of the base plate 60 causes the cartridge A held in the holder portion 62 to be stopped.
1 passes through the second window portion 134 and the return port, and the stacker 24
Returned to the end of the. The cartridge A1 is returned to the stacker 24 in the direction opposite to the storage direction of the unused cartridge A that has not been searched yet. In this state, the keep solenoid 106 is turned off (S10
4), the pressing plate 99 is the pressing portion 9 of the upper and lower arms 91, 92.
It swings in the direction of releasing the pressure of 5, 96. As a result, the upper and lower arms 91, 92 have tension coil springs 97,
The stacker 24 is rotated in the opening direction by the elastic force of 98.
The holding of the cartridge A1 returned inside is released. When the holding of the cartridge A1 is released, the LED ₁₇ is turned off and the LED ₁₂ is blinked (S105). When the first cartridge A1 is returned, the LED ₁₂
In addition to blinking, LED ₁₄ and LEDs ₁ to ₈ are lit. This indicates that the first cartridge A1 has been returned, the second cartridge A2 is in the process of being searched in the roll film carrier 1, and eight cartridges A waiting to be searched remain in the stacker 24. In this way, the position of the cartridge A is displayed by lighting the LED, and the LE corresponding to the cartridge A for which the search is completed is performed.
By displaying D in a blinking manner, it is possible to display the number of cartridges waiting to be searched and the number of the cartridge A currently searched.

Thereafter, the base plate 60 is moved in the N direction by the reverse rotation of the fourth motor 75 (S106). When both the third and fourth sensors 83 and 84 are turned on and it is detected that the base plate 60 and the roll film carrier 1 have moved to the neutral position, the fourth motor 75 is stopped and the base plate 60 moves. Is stopped (S107, S108). Next, in step S109, the third motor 70 is driven to rotate in the reverse direction, and the slider 6
1 is moved from the initial position to the second sensor front stop position by a fixed distance. When the slider 61 moves to the second sensor front stop position, the holder portion 62 faces the M direction.

Discharge of Cartridge A As shown in FIG. 28, in the cartridge discharge routine,
The last-loaded cartridge An or the currently loaded cartridge A when the interrupt mode is set is discharged from the supply unit 6 and returned to the cartridge container 24. The operation in this routine is different from the operation in the replacement routine of the cartridge A shown in FIGS. 24 to 27, and the front surface 38 of the carrier is not opened or closed. In step S115, FIG.
The same operation as steps S64 to S68 shown in FIG. 4 is performed. That is, if the vertical scan is executed, the base plate 60 is moved along the vertical scan direction, and the base plate 60 and the roll film carrier 1 are moved to the neutral position. Steps S116 to S119
Then, the same processing as steps S69 to 72 shown in FIG. 24 is performed, and the cartridge A loaded in the supply unit 6 is held. In steps S120 to S129, FIG.
6, the same processing as steps S88 to S108 shown in FIG. 27 is performed. That is, the slider 61 is moved to the initial position (S120 to S122), the base plate 60 is moved to the stop position at the end in the P direction, and the cartridge A held in the holder portion 62 is returned to the tail end in the stacker 24. (S1
23-126). Then, after releasing the holding of the returned cartridge A, the base plate 60 is moved in the N direction,
The base plate 60 and the roll film carrier 1 are moved to the neutral position (S127 to S129).

In step S130, it is determined whether or not the interrupt mode is set. If the interrupt mode is set, the process returns. If it is not in the interrupt mode, the last cartridge An is returned, so it is not necessary to prohibit removal of the stacker 24 and prohibition of increase / decrease of the cartridge A. Therefore, in step S131, the first motor 3
6 is driven in the reverse rotation, and the moving claw portion 31 is moved to the initial position. As a result, the moving claw portion 31 retreats from the inside of the stacker 24, so that the engaging portions 31 a, 31 of the moving claw portion 31 are removed.
b does not engage with the bottom wall of the stacker 24, and the stacker 24 can be removed. Furthermore, step S
At 132, the solenoid 51 is turned off. As a result, the prohibiting lever 54 rotates about the support shaft 53 by the elastic force of the tension coil spring 55 and moves to a position retracted from the opening 24 a of the stacker 24.

Although illustration of steps is omitted in FIG. 28, it indicates that the cartridge A is grasped or mis- grasped, that the cartridge A has fallen off while the slider 61 or the base plate 60 is moving, and that the slider 61 is not shown. And base plate 6
In order to indicate the movement completion of 0 or the movement error,
A predetermined LED is turned on, turned off, and blinked.

As described above, since the LEDs _{1 to 17} that represent the moving path of the cartridge A are turned on and off in response to the operation of the cartridge loader 21, the operator can move the cartridge. Can be recognized, and there is no anxiety such as whether or not the cartridge A is surely loaded in the roll film carrier 1. Furthermore, the cartridge A
When a defective conveyance occurs, the LED corresponding to the defective portion blinks, so that the operator can easily identify at which point the defective conveyance occurs, and the operator can identify the cause of the defective conveyance. Appropriate measures can be taken swiftly, and work efficiency of recovery work is improved accordingly. In addition, L representing the movement route in the stacker 24
The ED lights up for the number of cartridges A waiting for the search and blinks for the number of cartridges A after the search. It is possible to easily determine whether or not the search for A is being performed, and it becomes easy to decide the setup of the subsequent work.

As the position display means, LEDs ₁ to LED are used.
_Although the case of using ₁₇ is shown, the means of display is LED
However, the same display may be made using a liquid crystal or a display, for example. Further, the number of cartridges waiting to be searched and the number of the cartridge to be searched may be displayed using a 7-segment LED.
