Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to cartridge loaders and roll film carriers. That is, a cartridge reader and a roll that are attached to a microreader that projects an image on a microfilm onto a screen for viewing, a reader printer that further copies the image, a microscanner that causes a CCD that is a solid-state image pickup device to read the image, and other image projection devices. It relates to a film carrier.

[0002]

2. Description of the Related Art Generally, a large amount of microfilm is stored and used, and in using the microfilm, quick retrieval and copying are required. By the way, conventionally, microfilm retrieval, copying, etc. by a reader printer or the like have been performed by sequentially and manually loading microfilm cartridges into the roll film carrier and ejecting used cartridges. It was
In other words, a person manually ejects the cartridge and newly loads it, that is, replaces the cartridge each time each search, copy, or the like is completed. Therefore, it has been pointed out that it is difficult to replace the cartridge, and it is difficult to perform a quick search and copy.

Now, in order to deal with such a problem, recently,
Cartridge loaders or automatic loading devices for microfilm cartridges have been developed. This cartridge loader is attached to a reader printer as an auxiliary device and automatically and sequentially loads and loads the microfilm cartridges to be used on the roll film carrier, and at the end of searching, copying, etc. I was supposed to take out the cartridge and return it.

[0004]

By the way, the following problems have been pointed out in such a conventional example. That is, first of all, when the retrieval, copying, etc. of the microfilm of the last cartridge stored in the cartridge loader have been completed and returned from the roll film carrier, that is, all the cartridges stored in the cartridge loader have been returned. It has been necessary to detect the end of the microfilm in order to stop the operation of the cartridge loader when the search, copy, etc. are completed. That is, in order to stop the operation of the cartridge loader that loads the cartridge into the roll film carrier or returns the cartridge from the roll film carrier, it is necessary to detect the completion of all searches, copying, etc. It was a problem in terms of automation such as searching and copying.

Secondly, the roll film carrier is generally capable of vertical scanning in order to correct the vertical displacement of the image when searching or copying the microfilm in the loaded cartridge. That is, in order to move the image on the microfilm in the vertical direction on the screen, a vertical scan is often performed in which the roll film carrier is slightly moved, for example, back and forth with respect to the apparatus main body such as a reader printer. Then, when such a vertical scan is performed, the roll film carrier is displaced from the original position where the projection optical axis of the apparatus main body is on the film center line in the longitudinal direction of the roll-shaped microfilm, and at the same time with the cartridge loader. In order to load and return the cartridge, it will be displaced from its original position. Therefore, when returning the cartridge and loading the next cartridge, that is, when replacing the cartridge, it is necessary to move and return the roll film carrier to the original position, which is the neutral position, in order to correct the positional deviation due to the vertical scan. I needed it. Therefore,
The replacement of each cartridge was not carried out smoothly, and problems with automation of searching and copying microfilm were pointed out, and it took time to replace the cartridge, and there was a problem from the viewpoint of quick searching and copying of microfilm. .

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example. First, in claim 1, a moving member for moving the cartridges of the cartridge accommodating portion together. Proposes a cartridge loader that automatically stops operation when all searches are completed by measuring the amount of movement from the initial position until the first cartridge is set on the set member and recognizing the number of cartridges. The purpose is to do. Further, in the present invention, it is an object of the present invention to propose a roll film carrier in which the cartridge can be smoothly replaced by returning to the original position during the rewinding of the microfilm when the vertical scan is performed. .

[0007]

[Means for Solving the Problems] Claim 1 is as follows. That is, the cartridge loader is attached to an image projection device that projects an image of microfilm. Then, a cartridge storage unit for storing a plurality of the microfilm cartridges side by side, a loading mechanism for sequentially guiding the cartridges from the cartridge storage unit to the film carrier of the image projection apparatus, and the cartridges sequentially from the film carrier. It has an ejection mechanism for returning the cartridge to the cartridge accommodating portion, and control means for controlling the operations of the loading mechanism and the ejection mechanism. And
The loading mechanism of the cartridge loader moves together the cartridges housed in the cartridge housing unit and sets one cartridge to be loaded into a set member, and the moving member through the cartridges. And a setting member which is located on the opposite side of the member and guides the set cartridge to the film carrier afterwards. The control means measures the amount of movement of the moving member from the initial position until the first cartridge is set on the setting member, and recognizes the number of each of the cartridges stored in the cartridge storing portion. And based on this,
When the last retrieval of the microfilm of the cartridge is completed and the cartridge is returned to the cartridge storage portion by the ejection mechanism, the operation of the loading mechanism and the ejection mechanism is controlled to stop.

Claim 2 is as follows. That is, this roll film carrier is attached to an image projection device for projecting an image of a microfilm, and a cartridge of the microfilm is loaded using a cartridge loader, ejected and returned, and sequentially replaced. . Since this roll film carrier performs a vertical scan for moving the image of the microfilm of the loaded cartridge, the projection optical axis is on the film center line and the roll film carrier is located at the position corresponding to the cartridge loader. Moving means for moving the roll film carrier from the position to some extent with respect to the apparatus main body, reel driving means for winding and rewinding the microfilm, and rewinding for rewinding the searched microfilm by the reel driving means. And a control means for controlling the moving means to move and return the roll film carrier moved by the vertical scan to the original position.

[0009]

The function of claim 1 is as follows. In this cartridge loader, a microfilm cartridge is loaded into the roll film carrier from the cartridge storage portion, and after that, it is returned from the roll film carrier to the cartridge storage portion, and the cartridges are sequentially replaced. Then, the control means performs the following control. First, the number of cartridges stored in the cartridge storage unit is measured by measuring the amount of movement from the initial position of the moving member that moves each cartridge in the cartridge storage unit until the first cartridge is set on the setting member. Is recognized, and the number of exchanges is calculated. Based on this, when the return of the last cartridge is completed, that is, when the search for the microfilm in each of the stored cartridges is completed, the cartridge loader automatically stops its operation immediately.

Claim 2 is as follows. In this roll film carrier, cartridges are loaded and returned by a cartridge loader, and the cartridges are sequentially replaced, and when searching for microfilm in the loaded cartridges, vertical scanning is performed as necessary, and the rolls are moved by the moving means. The film carrier is moved from its original position. Then, the control means automatically moves and returns the roll film carrier to the original position by using the moving means during the rewinding of the microfilm for which the search has been completed. Therefore, the roll film carrier is always in the original position when the cartridge is exchanged, and in the corresponding position where the roll film carrier is loaded and returned with the cartridge loader, so that the cartridge can be exchanged smoothly.

Is connected to a motor (not shown) via the drive shafts 14 and 15 of the respective reel drive means. In the microfilm F, the rewinding reel 4 and the winding reel 5 are properly reversed. By being rotationally driven, it is conveyed between the reels 4 and 5 via the pressure-bonded glasses 2 and 3 while being wound and rewound. Reference numeral 16 denotes a lamp which is a light source. Light from the lamp 16 is reflected by a reflection mirror 17 and condensed by a condenser lens group 18, and pressure-bonded glass 2, 3
The microfilm F located between them is irradiated with light from below and passes through. With such a light flux, the image on the microfilm F is enlarged and projected on the screen 20 in the reader mode through the projection lens 19 for viewing, and in the print mode, it is projected and exposed on a photoconductor (not shown) to be copied. It When all of these are completed, the microfilm F is rewound and all are rewound on the rewinding reel 4.

A reel driving means, which is a means for handling the microfilm F, attached to the roll film carrier 1 is provided for each of the rewinding reel 4 and the winding reel 5 and drives them respectively. Axis 1

Signals from the eighth and fifth switches 79 and the like are input to the microcomputer MC which is the control means through the port T, and from the microcomputer MC through the port T, the first motor 36, the second motor 41, the 3 motor 5
Signals corresponding to the above-described input signals are output to the 7, fourth motor 60, solenoid 66, and the like. By the control by the microcomputer MC as described above, each operation of the cartridge loader 21 described above is performed, and the moving claw portion 31 and the setting rod 33 of the loading mechanism 22, the front surface portion 38 of the supply portion 6 of the roll film carrier 1, the discharging mechanism. The holder part 50, the take-out plate 51, etc. of 23 operate as described above.

Further, such a microcomputer MC
According to this, the following control is performed. That is, with respect to the cartridge A loaded in the supply unit 6 of the roll film carrier 1 by the loading mechanism 22, before the microfilm F is searched and rewinded and ready to be taken out, the holder unit 5 of the ejection mechanism 23 is previously.
At 0, the holding is performed. That is, for example, immediately after the cartridge A is loaded in the supply unit 6 of the roll film carrier 1, the microfilm F is first fed out during loading, when the loading is completed, and finally the microfilm F is rewound. At a proper timing such as at the start of rewind and during rewind, that is, at a proper timing from the loading to the end of the rewind, a forward rotation signal to the fourth motor 60 of the discharging mechanism 23, a reverse rotation signal to the third motor 57, Solenoid 6
An ON signal and the like are sequentially output to 6. Ejecting mechanism 2
The holder part 50 of 3 moves toward the end in the K direction, which is directed in the M direction, and the cartridge A being loaded is moved to the upper arm 6 thereof.
4. The lower arm 65 is closed and held.

In the present invention, the following control is further performed on the cartridge loader 21 by the microcomputer MC which is such control means. That is, the microcomputer MC that is the control unit measures the amount of movement from the initial position of the moving claw portion 31 that is the moving member until the first cartridge A is set on the setting rod 33 that is the setting member, and the cartridge MC The number of cartridges A group stored in the storage section 24 is recognized. Then, based on this, when the retrieval of the microfilm F of the last cartridge A _n is completed and returned to the cartridge storage section 24 by the ejection mechanism 23, the operations of the loading mechanism 22 and the ejection mechanism 23 are stopped. To control. This will be described in detail. First, as shown in FIG. 3, the cartridge A is stored in the cartridge storage portion 24. The number of the cartridges A stored in this way is from a minimum of 1 to a maximum capacity of N. Various numbers are possible. By the way, regarding the moving claw portion 31,
From the initial position where the fifth switch 79 is turned on, the first cartridge A is set on the set rod 33 via the cartridge A group, and the movement amount until the first switch 37 is turned on is determined by the CPU of the microcomputer MC. Alternatively, the number of the cartridges A accommodated in the cartridge accommodating portion 24 can be easily recognized by measuring with the counter.

For example, when the number of cartridges A accommodated in the cartridge accommodating portion 24 is N, which is the maximum capacity,
The initial movement amount of the set rod 33 is, for example, Rmm,
Further, assuming that the width of one cartridge A is, for example, 25.4 mm, it becomes as follows. That is, when the initial movement amount of the set rod 33 is, for example, Rmm plus 25.4 mm, the number of cartridges A accommodated in the cartridge accommodating portion 24 is recognized as N minus 1. The initial movement amount of the set rod 33 is, for example, Rmm plus 25.4 mm × 2.
In this case, the number of the cartridges A stored in the cartridge storage portion 24 is recognized as N minus 2.

In this way, the cartridge storage section 24
The number of cartridges A stored in the cartridge is recognized, and the required number of replacements of the cartridge A is also minus 1 from the number.
It is understood as what was done. Then, after the fact, the following control becomes possible. That is, when the search for the micro film F in the last cartridge A _n is completed in the roll film carrier 1 and the cartridge A _n is returned to the cartridge storage section 24 by the ejection mechanism 23, the microcomputer MC causes the first motor The drive signals to the 36, the second motor 41, the third motor 57, the fourth motor 60, the solenoid 66, and the like are stopped, and thus the operations of the cartridge loader 21 such as the loading mechanism 22 and the discharging mechanism 23 are stopped. The cartridge loader 21 is controlled in this way.

Next, the control means of the roll film carrier 1 moves the roll film carrier 1 by the above-described vertical scan during the rewind of rewinding the microfilm F for which the search is completed by the reel driving means.
Is controlled to be returned to the original position by the moving means V. That is, in the roll film carrier 1, the searched microfilm F is rewound onto the reel 4 for rewinding by the drive shafts 14 and 15 of the reel drive means.
The control means such as the microcomputer MC sends a drive signal to the stepping motor W of the moving means V immediately after sending such a rewind signal to the motor of the reel driving means, so that the roll film carrier on which the vertical scan is performed. 1 is returned to the original position which is the neutral position described above. That is, when a vertical scan is performed on the roll film carrier 1, the number of drive pulses of the stepping motor W at the time of the vertical scan is counted to store the movement amount of the roll film carrier 1 at the time of post-rewind. In the above, the drive signal for rotating in the opposite direction with the same number of drive pulses is again sent to the stepping motor W. As a result, the roll film carrier 1 is corrected and moved by the amount of movement during the vertical scan, and is controlled to move and return to the original original position before the vertical scan. Since the roll film carrier 1 is not integrated with the cartridge loader 21 but individually attached to the reader printer, if the stepping motor W has a torque sufficient to move only the roll film carrier 1. Well, it does not require a large capacity, so there is an advantage that it is also excellent in cost.

The present invention is as described above. Therefore, it operates as follows. 8, FIG. 9, and FIG.
3A and 3B are schematic plan views for explaining the loading operation, the loading operation and the discharging operation, the discharging operation, and the like by the cartridge loader 21 and the like. FIG. 1A is an initial stage thereof, FIG. 3) The figure shows the end stage. Furthermore, FIG.
1, FIG. 12, FIG. 13, FIG. 14, FIG. 15, FIG.
11 is a flowchart of the control of this embodiment, and FIG.
Shows the basic control, and FIGS. 12 to 17 show the respective routines. The operation of the embodiment will be described below with reference to these drawings.

First, the outline of the operation will be described with reference to FIG. When the start switch is turned on in step 1 of FIG. 11, initial setting is performed in step 2. This initialization routine will be described later with reference to FIG. After the initial setting, the flow proceeds to step 3, and the first cartridge A ₁ is loaded into the roll film carrier 1. The loading routine for the first cartridge A ₁ will be described later with reference to FIGS. 13 and 8. When the loading of the first cartridge A ₁ is completed in this way, the next step 4 is to search the microfilm F of the cartridge A ₁ . This search routine will be described later with reference to FIGS. 14, 8 and 9. Now,
When the search for the microfilm F in the cartridge A ₁ is completed, the flow proceeds to step 5.

In step 5, the first cartridge A ₁ is discharged and the second cartridge A ₂ is loaded.
That is, the cartridge A is replaced, and details thereof will be described later with reference to FIGS. 15, 16 and 9.
Next, the flow proceeds to step 6, and it is determined whether the search or the like has been completed for all the cartridges A currently stored in the cartridge storage section 24 of the cartridge loader 21. This determination is performed by determining the end of the search for the microfilm F of the last cartridge A _n based on the recognition of the number of the cartridge A groups stored in the cartridge storage unit 24 as described above. If not, the process returns to step 4, and steps 4, 5 and 6 are repeated again to search, eject, and eject each cartridge A from the _second cartridge A ₂ onward.
Loading etc. are carried out sequentially. On the other hand, when it is determined in step 6 that the search is completed, the process proceeds to the next step 7, in which the last cartridge A _n loaded in the roll film carrier 1 is ejected and returned to the cartridge accommodating portion 24. The details will be described later with reference to FIGS. 17 and 10. The cartridge loader 21 and the like generally operate in this manner.

The details will be described below. First, Fig. 1
Step 2 of 1, that is, the initialization routine of FIG. 12 will be described. That is, in this initialization routine, first, in step 8 of FIG. 12, whether or not the second switch 42 is turned on, that is, the front surface portion 38 of the supply section 6 of the roll film carrier 1 is in the closed state along the H direction. It is determined whether or not it is in the initial position (see FIG. 1). If it is determined in step 8 that it is not in the initial position, that is, if it is not in the initial position, the second motor 41 is driven in forward rotation in step 9, but in step 8, the second switch 42 is turned on and the front portion 3
When it is determined that 8 is in the initial position in the closed state, the second motor 41 is stopped in step 10. Further, in step 11, it is determined whether or not the third switch 67 is on, that is, whether or not the holder portion 50 (see FIG. 2) of the ejection mechanism 23 of the cartridge loader 21 is at the initial position at the end in the J direction. It Then, when it is determined to be no in step 11,
In step 12, the third motor 57 is driven in forward rotation, but if it is determined in step 11 that the third switch 67 is on and the holder 50 is in the initial position, step 13
Then, the third motor 57 is stopped. At the same time, it is determined in the next step 14 whether or not the fourth switch 68 is on, that is, whether or not the holder portion 50 faces the L direction.
Then, if it is determined NO in step 14, the fourth motor 60 is driven in reverse rotation in step 15,
In step 14, the fourth switch 68 is turned on and the holder portion 5
If it is determined that 0 faces the L direction, step 16
Then, the fourth motor 60 is stopped.

Further, in the next step 17, whether or not the fifth switch 79 is turned on, that is, the moving claw portion 31 (see FIG. 1) which is the moving member of the loading mechanism 22 is set to the initial position at the end in the D direction. It is determined whether or not there is. And step 1
If it is determined to be No in step 7, the first motor 36 is driven in reverse rotation in step 18, but in step 17
When it is determined that the switch is on and the moving claw portion 31 is in the initial position, the first motor 36 is stopped in step 19.
As described above, in the initial setting routine, the front surface portion 38, the holder portion 50, the moving claw portion 31 and the like are set to the initial position and the initial direction. Then, the flow returns to step 3 in FIG.

Next, step 3 of FIG. 11, that is, the loading routine of the first cartridge A ₁ of FIG. 13 by the loading mechanism 22 will be described with reference to FIG. First, from the above-described initial setting state (see (1) of FIG. 8),
In step 20 of FIG. 13, the moving claw portion 31 moves the first motor 3
It is moved in the E direction by the drive of 6 normal rotation,
In step 21, the movement amount Smm is measured by the CPU or the counter of the microcomputer MC,
Temporarily stored in RAM. As a result, the group A of cartridges in the cartridge housing 24 is also moved in the direction E, the first first cartridge A ₁ is set on the set rod 33, and the first switch 37 is turned on in step 22, and then in step 23. The first motor 36 is reversed and driven by reverse rotation, the moving claw portion 31 is reversed and moved in the D direction,
When the fifth switch 79 is turned on in step 24, the moving claw portion 31 returns to the initial position and stops in step 25.

Next, at step 26 in FIG. 13, the front surface portion 38 of the supply portion 6 of the roll film carrier 1 is driven 90 degrees forward from the initial position in the closed state by the second motor 41 being driven in the reverse rotation. It is rotated to the open state along the I direction. Then, in step 27, the cartridge A ₁
The lock of the set rod 33 in which is set is released, and the set rod 33 is moved from the cartridge storing portion 24 side to the front face portion 3
The cartridge A ₁ is moved to the 8 side, and the cartridge A ₁ is held by the front surface portion 38. Thereafter, in step 28, the second motor 41 is driven in forward rotation, the front face portion 38 holds the cartridge A ₁ and rotates in the H direction (see (2) in FIG. 8), and the next step 29 When the second switch 42 is turned on, the second motor 41 is stopped in step 30, and the cartridge A ₁ is loaded and positioned in the supply section 6 of the roll film carrier 1. After the fact, the set rod 33 moves to the cartridge storage section 24 side and is locked again. Then, in the next step 31, the roll film carrier 1 (see FIG. 6) directs the microfilm F of the first cartridge A ₁ thus loaded from the rewinding reel 4 to the winding reel 5. Loading to send out is performed. As described above, in the loading routine of the cartridge A ₁ , the moving claw portion 31 is reciprocated from the initial position, the first cartridge A ₁ is loaded by the loading mechanism 22, and the microfilm F is loaded. Then, the flow returns to step 4 in FIG.

Next, step 4 of FIG. 11, that is, FIG.
The search routine will be described with reference to FIGS. 8 and 9. In this way, in the roll film carrier 1, when the loading of the _first microfilm F of the cartridge A ₁ is completed, the process proceeds to the next step 32. Then, the ejection mechanism 2 of the cartridge loader 21
First, in step 32, the holder portion 50 of No. 3 faces the M direction by driving the fourth motor 60 in the forward rotation, and in step 33, by driving the third motor 57 in the reverse rotation, the K direction. And the solenoid 66 is turned on so that the upper arm 64 and the lower arm 65 of the holder unit 50 move the cartridge A ₁ already loaded in the supply unit 6 of the roll film carrier 1 in step 34. Hold it and wait for a while after the fact. At that time, the take-out plate 51 of the discharging mechanism 23 is moved and locked up to the end in the N direction with the movement of the holder 50 (see FIG. 8 (3)).

Then, in the roll film carrier 1 (see FIG. 6), while the microfilm F is being conveyed between the rewinding reel 4 and the winding reel 5, the desired image of the desired frame is manually or It will be searched automatically.
That is, the microfilm F transported in the roll film carrier 1 is stopped when the desired image of the target frame is searched between the pressure-bonded glasses 2 and 3.
It is browsed at 0 and copied if necessary.

While the roll film carrier 1 is being searched in this way, in the cartridge loader 21, the moving claw portion 31 of the loading mechanism 22 is rotated forward by the first motor 36 in step 35. Is moved again from the initial position in the E direction by the driving of the cartridge, and the amount of the movement is the width 2 for one cartridge A with respect to the initial movement amount Smm counted and stored in step 21 described above.
5.4 mm is added, and the cartridge A ₂ to be loaded next is set on the set rod 33. When the movement is completed, in step 36, the first motor 36 is immediately driven in the reverse rotation to move the moving claw portion 31.
Is reversed and moved in the D direction, and when the fifth switch is turned on in step 37, the moving claw portion 31 returns to the initial position and stops in step 38 (see (1) of FIG. 9). By such an operation, the cartridge A ₂ is prevented from being caught between the moving claw portion 31 and the first switch 37. The moving speed of the moving claw portion 31 is
Similarly, when the first cartridge A ₁ is set, it is set so as not to be caught, and in the case of the _second cartridge A _{2 and} thereafter, the first cartridge A ₁
It is set faster than the moving speed in. Thus, in the search routine, the microfilm F is searched, copied, and the like, and the holder 50 of the ejection mechanism 23 is also used.
Holds the cartridge A _1, and the moving claw portion 31 of the loading mechanism 22 is reciprocated from the initial position to set the next cartridge A ₂ on the set rod 33. Then, the flow returns to step 5 in FIG.

Next, step 5 of FIG. 11, that is, the cartridge A replacement routine of FIGS. 15 and 16 will be described with reference to FIG. First, as described above, in the roll film carrier 1, when the search of the _first microfilm F of the cartridge A ₁ is completed, rewinding is performed, and the microfilm F is all rewound onto the rewinding reel 4. Become. That is, first, in step 39, a rewind signal is output to the motor of the reel driving means attached to the roll film carrier 1. When this rewind signal is output, if a vertical scan is performed, step 40 is immediately executed. Then, the drive signal is also output to the stepping motor W of the moving means V (see FIG. 4 (1)). That is, the search routine described above searches for the microfilm F,
When a vertical scan for moving the image up and down is being performed when copying or the like is performed, in this step 40, a drive signal in the reverse direction is output according to the number of drive pulses at the vertical scan, and stepping is performed. Motor W
Is driven to rotate by a predetermined amount, so that the roll film carrier 1 is moved and returned to the original position before the vertical scan.

Now, the processes of steps 41, 42 and 43 are performed in parallel with the process of step 40. That is, based on the rewind signal in step 39, the motor of the reel drive means is rotationally driven for rewind in step 41, and when the drive shaft 14 is reset in step 42, the drive of the motor in step 43 is stopped and the micro The film F is all rewound on the rewinding reel 4. Along with this, in the next step 44, the supply department 6
The front portion 38 of the cartridge is rotated 90 degrees in the I direction from the closed state to the opened state, and in step 45, the lock of the set rod 33 is released and the front portion 38 holds the next cartridge A ₂ (see FIG. 9). (2) See figure). Now, here, the flow is divided into a flow after step 46 and a flow after step 47, and waits for the end of these two parallel processes,
The process returns to step 6 in FIG.

First, the processing of step 46 and subsequent steps will be described. In step 46, the holder portion 50 of the discharging mechanism 23, which held the cartridge A ₁ in the previous step 34 and waits, causes the third motor 57 to rotate forward. Is driven to move to the end in the J direction, and in step 48, the third switch 6
When 7 is turned on, the third motor 57 is stopped and the holder 50 stops moving in step 49 (see FIG. 9 (2)). Then, in the next step 50, the holder unit 50 is driven in the reverse rotation of the fourth motor 60 to face the L direction,
When the fourth switch 68 is turned on in step 51, the fourth motor 60 is stopped in step 52. After that, the process proceeds to step 53, and first, the solenoid 66 is turned off to release the holding of the cartridge A ₁ , the lock of the takeout plate 51 of the ejection mechanism 23 is released, and the takeout plate 51 holds the cartridge A _1. It moves in the P direction and returns the cartridge A ₁ to the cartridge storage section 24. Then, the cartridge A ₁ is returned to the rearmost side of each of the cartridges A stored in the cartridge storage portion 24, and is returned in the opposite direction to the unused cartridge A which has not been searched yet (see FIG. 9). (3) See the figure). After that, the take-out plate 51 is moved to the end in the N direction and locked.

Next, the processing of step 47 and thereafter, which is performed in parallel with the processing of the holder 50 of the discharging mechanism 23, will be described. First, the front surface portion 38 of the supply unit 6 which has held the cartridge A ₂ in the previous step 45 and is in the open state is rotated in the H direction by the second motor 41 being driven in the forward rotation in step 47. When the second switch 42 is turned on in step 54, the second motor 41 is stopped in step 55, so that the next cartridge A ₂ is loaded and positioned in the supply section 6 of the roll film carrier 1 ((3 in FIG. 9). ) See figure). Along with this, the set rod 33 moves to the cartridge storage section 24 side and is locked again. Then, in the next step 56, the microfilm F of the cartridge A ₂ thus loaded in the supply section 6 of the roll film carrier 1 is sent out from the reel 4 for rewinding.

As described above, the flow after step 46 and the flow after step 47 described above are processed in parallel, and the flow waiting for the completion of both is returned. Thus, in this exchange routine, first, the first cartridge A ₁ for the roll film carrier _{1 is}
During the rewinding, the return to the original position before the vertical scan is performed, and then the first cartridge A ₁ is ejected.
The return and the loading of the next cartridge A ₂ are simultaneously performed in parallel. Then, the flow returns to step 6 of FIG. 11, and after that, each cartridge A is followed in accordance with the above description.
Steps 4, 5, and 6 are sequentially repeated, each search and replacement of the cartridge A are performed, and after the used one is returned to the cartridge storage unit 24, in step 6, the micro cartridges of all the cartridges A are replaced. Film F
When the search of is completed, the process proceeds to step 7.

By the way, the following cartridge A
Each cartridge A from ₂ to the last cartridge A _n
For each of the steps,
After the loading by the roll film carrier 1 is completed at step 53, the previous cartridge A is returned to the cartridge storage part 24 by the holder part 50 at step 53, and then held at the holder part 50 at steps 32, 33 and 34 described above. It is supposed to be done. That is, the holder part 50 moves in the M direction to the end in the K direction, and the upper arm 64 and the lower arm 65 of the holder part 50 move.
The cartridge A of the microfilm F which is being searched for after the loading is completed is held. Then, the holder unit 50 holds the cartridge A and waits until the search is completed and the rewind of Step 43 is completed.

Finally, step 7, that is, the discharge routine of the cartridge A _n shown in FIG. 17, will be described with reference to FIG. In the discharging routine of the cartridge A _n , the discharging and returning of the cartridge A _n , which is finally taken out from the cartridge storage unit 24 and loaded, is performed from the supply unit 6 of the roll film carrier 1 to the cartridge storage unit 24. Unlike the case of the cartridge A replacement routine of FIGS. 15 and 16, in this case, the front face portion 38 of the supply unit 6 is not opened or closed.

That is, in the discharging routine of the cartridge A _n , first, in step 57 of FIG. 17, the last cartridge A _n in the supply unit 6 is held and the holder unit 50 of the discharging mechanism 23 which is in the standby state. The arm 64 and the lower arm 65 move to the end in the J direction when the third motor 57 is driven by forward rotation, the third switch 67 is turned on in step 58, and the third motor 57 is turned on in step 59. By stopping, the movement is stopped (see (1) in FIG. 10). Thereafter, in step 60, the holder 50 is driven in the reverse rotation of the fourth motor 60 to face the L direction, the fourth switch 68 is turned on in step 61, and the fourth motor 60 is stopped in step 62 (Fig. (See FIG. 10 (2)). Then, the process proceeds to the next step 63. First, the solenoid 66 is turned off to release the holding of the cartridge A _n , the lock of the takeout plate 51 of the ejection mechanism 23 is released, and the takeout plate 51 holds the cartridge A _n. While moving in the P direction, the cartridge A _n is returned to the cartridge storage section 24. And the cartridge A _n is
In the cartridge storage unit 24, the cartridge A is returned to the end of each cartridge A that has already been used and returned, and in the opposite direction to the direction of each cartridge A when stored in the previously unused state. It will be returned (see (3) in Figure 10).

As described above, for all the cartridges A stored in the cartridge storage portion 24 of the cartridge loader 21, the roll film carrier 1
The search, return, etc. are completed. As described above, in the cartridge loader 21, the cartridge A of the microfilm F is loaded by the loading mechanism 22 into the cartridge storage unit 2
4, the roll film carrier 1 is loaded, and after that, the discharge mechanism 23 returns the roll film carrier 1 to the cartridge storage portion 24, whereby the cartridge A is sequentially replaced.

In the cartridge loader 21, the following control is performed by the microcomputer MC which is the control means thereof. First, with respect to the moving member, that is, the moving claw portion 31 of the loading mechanism 22 that moves the respective cartridges A in the cartridge housing portion 24, the first cartridge A ₁ is set on the loading setting member, that is, the setting rod 33 from its initial position. By measuring the amount of movement until the cartridge is moved, the number of the cartridge A groups housed in the cartridge housing section 24 is recognized, and the number of times the cartridge A has been replaced is calculated. And based on this,
When the search for the microfilm F of the last cartridge A _n and the return are completed, the loading and returning operations of the loading mechanism 22 and the ejection mechanism 23 are automatically stopped. In this way, in the cartridge loader 21, when all the searches for the microfilm F of each cartridge A stored in the cartridge storage portion 24 are completed, the respective operations are automatically stopped immediately.

On the other hand, in the roll film carrier 1, the cartridge A is loaded and returned by the cartridge loader 21 as described above, and the cartridge A is exchanged sequentially. At the time of searching the microfilm F of the loaded cartridge A, etc. Vertical scanning is performed as necessary, and the roll film carrier 1 is moved from the original position by the moving means V. In the roll film carrier 1, the roll film carrier 1 moved by the vertical scan is re-wound by the control means during the rewinding of the microfilm F for which the search and the like have been completed.
The moving means V is used to automatically move and restore the original position. Therefore, the roll film carrier 1 is corrected in position misalignment, and accurately returns to the corresponding position for loading and returning the cartridge A with the cartridge loader 21, so that the next return of the cartridge A and the next cartridge are performed. Loading of A is done smoothly.
As described above, when the cartridge A is replaced, the roll film carrier 1 is always in the original position, and the replacement of the cartridge A can be smoothly performed.

Incidentally, the cartridge loader 21 of the illustrated example
The roll film carrier 1 also has the following advantages. First of all, this cartridge loader 21
The holder unit 50 of the discharging mechanism 23 of the roll A rolls before the search and the rewind of the microfilm F of the cartridge A loaded in the roll film carrier 1 are completed, that is, before the cartridge A can be taken out as used. The supply section 6 of the film carrier 1 holds the loaded cartridge A and stands by. Therefore,
The cartridge A can be replaced at the same time as the search and the rewind are completed, and the replacement time of the cartridge A can be shortened. or,
When the loaded cartridge A is held by the holder unit 50, the vibration in the roll film carrier 1 is suppressed during the standby until the cartridge A is taken out.

Secondly, since the loading path B and the discharging path C of the cartridge A of the microfilm F are individually formed without overlapping, the cartridge A that has been used after the search, copying, etc. are completed. Ejection and loading of a new cartridge A for which retrieval, copying, etc. are performed next are performed almost concurrently. Therefore, the replacement time of the cartridge A can be shortened also from this aspect. Thirdly, when a jam of the microfilm F occurs, by opening the rotatable front part 38 of the supply part 6 of the roll film carrier 1,
Jam is easily processed. Fourthly, with respect to each of the cartridges A stored in the cartridge storage section 24 of the cartridge loader 21, processing such as searching and copying has not been performed yet, and the cartridges A to be loaded in the supply section 6 from now on. Since the orientation is different from the orientation of the cartridge A that has been returned after the processing such as retrieval and copying has been completed, the retrieval, copying, etc. for each cartridge A has already been performed only by such orientation of the cartridge A. Whether or not it has been done, that is, whether or not it has been used, can be easily distinguished and determined.

[0060]

As described above, in the cartridge loader according to the first aspect of the present invention, as the moving member for moving the cartridges in the cartridge accommodating portion together, the first cartridge from the initial position is set as the loading member. By measuring the amount of movement until the cartridge is set and recognizing the number of cartridges, the following effects are exhibited. That is, when the searching, copying, etc. of the microfilms of all the cartridges housed in the cartridge housing section are completed, the operations such as loading and returning of the cartridge loader are automatically stopped. As described above, it is not necessary to detect the end of the search or the copy, and the automation of the search or the copy of the microfilm is promoted.

Further, as described above, the roll film carrier according to the second aspect of the present invention automatically sets the roll film carrier, which has been vertically scanned during the rewinding of the microfilm, during the search, the copy, etc., to the original position. By doing so, the following effects are exhibited. That is, all the cartridges can be replaced smoothly, and unlike the conventional example of this kind, it is not necessary to return the roll film carrier to the original position for each replacement of the cartridges, and it is possible to automate the search and copying of the microfilm. As a result, the time for cartridge replacement is reduced, and quick retrieval and copying of microfilm are realized.
