2. Description of the Related Art Microfilms are generally stored and used in large quantities, and in using them, quick retrieval, copying, etc. are required. By the way, conventionally, microfilm retrieval and copying with a reader printer or the like are performed by sequentially and manually loading microfilm cartridges into the roll film carrier and ejecting used cartridges. It was
In other words, every time the search, copy, etc. of each cartridge is completed, a person manually ejects the cartridge and newly loads it, that is, replaces the cartridge. 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, etc., and automatically and sequentially takes out and loads the microfilm cartridges to be used in the roll film carrier, and becomes used after the completion of searching, copying, etc. It was supposed to eject and return the cartridge. In addition,
In such a conventional example, the front surface portion of the supply portion of the roll film carrier, that is, the front surface portion of the supply portion for loading and positioning the cartridge so as to be loaded, is configured immovably with respect to the loading path.

[0004]

By the way, the following problems have been pointed out in such a conventional example. That is, in the conventional cartridge loader and roll film carrier, generally, a loading path for newly loading a microfilm cartridge to be used and a discharging for discharging and returning a used cartridge after completion of searching, copying, etc. The route was not formed as a completely different route, such as overlapping at least in part. in this way,
Since the loading route and the discharging route follow the same route, the next new cartridge is loaded after waiting for the used cartridge to be discharged, which requires time to replace the cartridge, which is a problem. And even the situation where it does not change much in time with the conventional manual method occurs,
It has been pointed out that the long time to replace the cartridge may hinder the quick retrieval and copying of the microfilm.

In view of such circumstances, the present invention has been made to solve the problems of the above-mentioned conventional example, in which the loading path and the discharging path of the microfilm cartridge are formed separately, and the supply By opening and closing the front part of the unit, the time for replacing the cartridge is shortened, and the discharging and loading of the cartridge can be performed quickly.
And the purpose is to propose the supply department of roll film carrier.

[0006]

According to a first aspect of the present invention, there is provided a roll film carrier for an image projection apparatus for projecting an image on a microfilm. A loading path for loading the microfilm cartridge and an ejection path for ejecting the used cartridge are formed separately. Claim 2 relates to a cartridge loader attached to an image projection device for projecting an image on a microfilm. Then, the microfilm cartridge to be used is sequentially taken out from the cartridge storage section, and the loading mechanism for guiding the cartridge to the supply section of the roll film carrier of the image projection apparatus and the used cartridge are sequentially transferred from the supply section. And a discharge mechanism for returning the cartridge to the cartridge storage portion. Then, the loading path by the loading mechanism and the discharging path by the discharging mechanism are individually formed. Claim 3 is a roll film carrier of an image projection device for projecting an image of a microfilm,
The present invention relates to a supply unit of the microfilm cartridge. Then, the front portion corresponding to the loading path of the cartridge is rotated to be opened and closed, and the opening and closing of the cartridge position the loading.

[0007]

According to the roll film carrier of the image projection apparatus of claim 1 and the cartridge loader of claim 2, the loading path and the discharging path of the microfilm cartridge are
It is formed individually. That is, the loading path from the cartridge storage section to the supply section of the roll film carrier and the discharge path from the supply section to the cartridge storage section follow different paths without overlapping. Furthermore, in order to realize this, in the supply unit according to the third aspect, the cartridge is loaded and positioned by opening and closing the front surface thereof. Now, the ejection of the cartridge for which the searching and copying have been completed and the loading of the cartridge for which the searching and copying are to be performed next can be performed almost concurrently. Therefore, the replacement time of the cartridge is shortened, and the discharging and loading of the cartridge can be performed quickly. Further, in the roll film carrier according to the third aspect, in addition to this, when a jam of the microfilm occurs, the jam treatment is easily performed by opening the front part of the supply section.

Reference numeral 68 denotes a fourth switch. This fourth switch 68 indicates that the upper arm 64, the lower arm 65, etc. of the holder portion 50 are oriented in the L direction at the end in the J direction. The projection 69 is switched on and detected.

Next, the take-out plate 51 of the discharging mechanism 23 is composed of bent plates arranged vertically as shown in FIG. 2, and extends along the guide groove on the horizontal frame 70 along the N and P directions in the figure. It can be slid horizontally (in the front-back direction parallel to the F and G directions in FIG. 1) to move. And this take-out plate 51
Has a take-out pawl 71 bent at a right angle at its tip, and when located at the end in the N direction, the take-out pawl 71 is located above the upper arm 64 of the holder 50 facing the L direction at the end in the J direction. , The lower claw 65 and the like, and on the other hand, when it is located at the end in the P direction, the take-out claw 71 is positioned so as to correspond to the return port in which the door 26 of the cartridge storing section 24 is opened. .. The take-out plate 51 is connected to the arm holding plate 58 of the holder 50 by the wire 73 via the pulley 72, and is interlocked in a predetermined manner. First, the take-out plate 51 is provided with a lock claw 74, and when the holder part 50 moves to the end in the K direction and is in a standby state, the take-out plate 51 is located at the end in the N direction and is attached to the tension spring 75 interposed. The locking claw 74 is locked by being locked by the bent piece of the guide plate 76 (state of FIG. 2).

Next, after holding the used cartridge A, the upper arm 64 and the lower arm 65 of the holder portion 50 in the standby state are moved in the J direction and rotated in the L direction, and the solenoid is used. When 66 is turned off and the holding of the cartridge A is released, the take-out plate 51 becomes as follows. That is, in this case, the projection 6 of the arm holding plate 58 of the holder 50 is
Since 9 has a positional relationship of pushing the take-out plate 51, such a pushing action causes the lock claw 74 and the guide plate 76 to move.
The take-out plate 51, which has been unlocked with the bent piece of FIG. 11 and thus has been unlocked, holds the cartridge A with its take-out claw 71, and is extended along the guide plate 76 in the P direction by the tension spring 75. To move. Then, the cartridge A is returned to the cartridge storage portion 24 from the return opening in which the door 26 is opened. Cartridge loader 2
The discharge mechanism 23 of No. 1 has such a structure.

Now, in this cartridge loader 21,
The orientation of the cartridge A initially set in the cartridge storage portion 24 before being taken out by the loading mechanism 22 and the orientation of the cartridge A returned to the subsequent cartridge storage portion 24 by the discharge mechanism 23 are different. .. FIG. 7 is a perspective view showing a state where the reel 4 is taken out from the cartridge A. (1) FIG.
(2) The figure shows the 3M type. Of course, the present invention is applicable to both types, but when each cartridge A is initially set in the cartridge storage section 24, generally, the spine label side 77 is the front side and the opening side 78 is the roll side. It is stored toward the supply unit 6 side of the film carrier 1 (state of FIG. 1). However, in the case of the present invention, the cartridge A returned after the fact is stored in the reverse direction, that is, with the spine label side 77 facing the supply section 6 side and the opening side 78 facing the front side.

Reference numeral 79 in FIG. 1 is a fifth switch,
The fifth switch 79 detects the direction of the cartridge A that is to be loaded next, and therefore the fifth switch 79 is provided.
It is arranged at a position facing the door 25 of No. 4, and is turned off on the back label side 77 of the cartridge A and turned on on the opening side 78. Therefore, when the fifth switch 79 is turned on, it is detected that all the cartridges A currently stored in the cartridge storage portion 24 have been used. It is to be noted that the cartridge A in the cartridge accommodating portion 24 is reversed in this way in the illustrated example because the upper arm 64 and the lower arm 65 of the holder portion 50 of the discharging mechanism 23 are used (see FIG. 2). The completed cartridge A is held from its spine label side 77, rotated from the M direction to the L direction, and at the end in the J direction, the takeout plate 5
This is because the take-out claw 71 of No. 1 is moved to the inside of the cartridge storing section 24 and returned with the back label side 77 as the rear and the opening side 78 facing the front side.

Further, in this cartridge loader 21, a loading path B by the loading mechanism 22 and an ejection path C by the ejection mechanism 23 are individually formed (see FIGS. 1 and 2). That is, in the roll film carrier 1, the loading path B for newly loading the cartridge A of the microfilm F and the discharging path C for discharging the used cartridge A are individually formed. .. In this way, the loading path B from the cartridge storage section 24 to the supply section 6 of the roll film carrier 1 and the supply section 6
The discharge route C from the cartridge storage unit 24 to the cartridge storage unit 24 follows another route without overlapping. For example, in FIG. 1, the cartridge A is loaded from the front side and ejected from the side afterward, so that the paths do not overlap.

The present invention is as described above. Therefore, it operates as follows. FIG. 8, FIG. 9, and FIG. 10 are schematic plan views for explaining the loading operation, the loading operation and the discharging operation, and the discharging operation by the cartridge loader 21 and the like,
FIG. 1 shows the initial stage, FIG. 2 shows the moving stage, and FIG. 3 shows the ending stage. Further, FIG. 11, FIG.
FIG. 13, FIG. 14, FIG. 15 and FIG. 16 are flowcharts of control of this embodiment, and FIG. 11 shows basic control.

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. The initialization routine will be described later with reference to FIG. After the initialization, 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 and} the like. For this search routine,
It will be described later with reference to FIG. Well, the first cartridge A
_When the search for the microfilm F of ₁ is completed, the flow proceeds to the main operation of step 5.

In the main operation routine, the first cartridge A ₁ is discharged and the second cartridge A ₂ is discharged.
Are almost simultaneously performed in parallel, the details of which will be described later with reference to FIGS. 15 and 9. After that,
In the next step 6, the search for the microfilm F in the _second cartridge A ₂ is performed, and the contents of this search routine are the same as those in step 4 described above.
It will be described later with reference to FIG. Next, the flow proceeds to step 7 and whether or not the fifth switch 79 is on, that is, whether or not 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. Is determined. And if not,
By returning to step 5 and repeating steps 5, 6, and 7, the ejection, loading, and retrieval of each cartridge A are performed. 5th switch 7 in step 7
When it is determined that the roll cartridge 9 is on, the process proceeds to the next step 8 to discharge the last cartridge A _n currently loaded in the roll film carrier 1 and to eject the cartridge storage unit 24.
Will be returned to. 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, first, it is determined whether or not the second switch 42 is turned on in step 9 of FIG. 12, that is, whether the front surface portion 38 of the supply unit 6 of the roll film carrier 1 is at the initial position in the closed state along the H direction. It is determined whether or not (see FIG. 1). When it is determined to be no in step 9, the second motor 41 is driven in normal rotation in step 10, and the second switch 42 is turned on in step 9 to turn on the front surface 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 11. Also, the next step 1
In 2, it is determined whether or not the third switch 67 is on, that is, whether or not the holder 50 is at the initial position of the end in the J direction (see FIG. 2). When it is determined to be no in step 12, it is determined in step 13 that the third motor 57 is driven in forward rotation, and in step 12, the third switch 67 is on and the holder portion 50 is in the initial position. Then, in step 14, the third motor 57 is stopped.

Further, in the next step 15, the fourth switch 6
It is determined whether or not 8 is on, that is, whether or not the holder unit 50 faces the L direction (see FIG. 2). Then, if it is determined to be no in step 15, the fourth motor 60 is driven in reverse rotation in step 16, the fourth switch 68 is turned on in step 15, and the holder portion 50 faces the L direction. If determined, in step 17, the fourth motor 6
0 stops. Thus, in the initial setting routine, the positions, directions, etc. of the front surface portion 38 and the holder portion 50 are set as in the initial state. 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. Figure 1
In step 18 of 3, the front surface portion 38 of the supply portion 6 of the roll film carrier 1 is rotated 90 degrees forward from the initial position in the closed state by driving the second motor 41 in reverse rotation (Fig. 8 (see (1) in FIG. 8), an open state is obtained along the I direction. Then, in step 19, the cartridge A
The lock of the set rod 33 in which ₁ is set is released, the set rod 33 moves from the cartridge housing portion 24 side to this front face portion 38 side, and the cartridge A ₁ is held by the front face portion 38 ((( 2) See figure). Then step 2
At 0, the second motor 41 is driven in the forward rotation, and the front portion 3
8 holds the cartridge A ₁ and rotates in the H direction, and when the second switch 42 is turned on in the next step 21, the second motor 41 is stopped in step 22, so that the cartridge A ₁ moves to the roll film carrier 1 The loading position is set in the supply unit 6 (see (3) in FIG. 8). Along with this, the set rod 33 moves to the cartridge storage section 24 side and is locked again. Further, the holder portion 50 of the discharging mechanism 23 faces the M direction by driving the fourth motor 60 in the forward rotation at step 23, and at the same time, step 24
Then, the third motor 57 is driven in the reverse rotation to move to the end in the K direction and enter the standby state (see FIGS. 8B and 8C). At that time, the discharge mechanism 23
The take-out plate 51 is moved to the end in the N direction and locked. Thus, in the loading routine of the cartridge A _1, with the first cartridge A ₁ is loaded by the loading mechanism 22, discharge mechanism 23 takes a predetermined standby state. Then, the flow returns to step 4 in FIG.

Next, step 4 of FIG. 11, that is, FIG.
The search routine will be described. First, with the roll film carrier 1 (see FIG. 6), step 25 in FIG.
Then, with respect to the first loaded microfilm F of the cartridge A ₁ , loading is performed so that the microfilm F is sent from the rewinding reel 4 to the winding reel 5. Then, in step 26, while the microfilm F is being conveyed between the rewinding reel 4 and the winding reel 5, desired image information of a target frame is manually or automatically searched. In the meantime, in step 27, the moving claw portion 31 of the loading mechanism 22 is driven by the forward rotation of the first motor 36 to move to the E position.
When the cartridge A ₂ to be loaded next is set to the set rod 33 and the first switch 37 is turned on, the cartridge A ₂ to be loaded next is moved in the direction , Step 29
Then, the first motor 36 stops (see FIG. 8 (3) and FIG. 9 (1)).

Now, when the desired image information of the desired frame is searched between the pressure bonding glasses 2 and 3, the microfilm F conveyed in the roll film carrier 1 is stopped in step 30 and is browsed on the screen 20. If necessary, after copying in step 31, in step 32,
It is rewound from the winding reel 5 to the rewinding reel 4. Now, when the search for the microfilm F is completed and rewinded in this way, in step 33, the loading mechanism 2 is loaded.
The second moving claw portion 31 is moved in the opposite D direction by the amount of the previous movement in the E direction (see FIG. 9 (1)). This D
The movement in the direction is performed by measuring the previous movement amount in the E direction by the CPU or the counter and temporarily storing it in the RAM, and based on this, reversely driving the first motor 36 by a corresponding amount. In this manner, in the search routine, the microfilm F is searched, copied, and the like, and the moving claw portion 31 of the loading mechanism 22 is moved in a predetermined manner. Then, the flow returns to step 5 in FIG.

Next, step 5 of FIG. 11, that is, the main operation routine of FIG. 15 will be described with reference to FIG. First, in step 34 of FIG. 15, the upper arm 64 and the lower arm 65 of the holder part 50 of the discharging mechanism 23 which has been in the standby state are used and the cartridge A ₁ in the supply part 6 which has been used is solenoid-operated. It is held by turning on 66 (see FIG. 9 (1)). Then, in the next step 35, the front surface part 38 of the supply section 6 is rotated 90 degrees in the I direction from the closed state to the open state again, and in step 36,
When the set rod 33 is unlocked, the next cartridge A
₂ is held by the front face portion 38 (see FIGS. 9A and 9B). At the same time, in step 37, the holder portion 50 holding the cartridge A ₁ is moved to the third motor 57.
Is driven by forward rotation to move to the end in the J direction, the third switch 67 is turned on in step 38, and the third motor 57 is stopped in step 39 (see FIG. 9 (1)).

The front face portion 38 which holds the next cartridge A ₂ in the previous step 36 and is in the open state, then, in step 40, is driven in the forward rotation of the second motor 41 to move in the H direction. It rotates and the second switch 4 is pressed in step 41.
When 2 is turned on, the second motor 41 is stopped in step 42, so that the next cartridge A ₂ is loaded and positioned in the supply section 6 of the roll film carrier 1 (see (3) in FIG. 9). Along with this, the set rod 33 moves to the cartridge storage section 24 side and is locked again.
Further, in step 43, the holder unit 50 moves the fourth motor 60.
By driving in the reverse rotation direction, the fourth switch 68 is turned on in step 44, and the fourth motor 60 is stopped in step 45 (see FIG. 9 (2)).

Then, the process proceeds to the next step 46. First,
The solenoid 66 is turned off to release the holding of the cartridge A ₁ , the lock of the take-out plate 51 of the ejecting mechanism 23 is released, and the take-out plate 51 moves in the P direction while holding the cartridge A ₁ to remove the cartridge A ₁ . It is returned to the cartridge storage unit 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 that has not been searched yet (see FIG. 9). See (2) and (3)). The take-out plate 51
After that, he is moved to the end in the N direction and locked. Then, in the next step 47, the holder portion 50 of the ejection mechanism 23 is
Is driven by the fourth motor 60 rotating in the forward direction.
It turns 0 degrees to face the M direction, and at step 48, the third
The motor 57 is driven to rotate in the forward direction to move to the end in the K direction, and the standby state is set again (see (3) in FIG. 9). As described above, in the main processing routine, first, the ejection / return of the first cartridge A ₁ and the loading of the next cartridge A ₂ are performed almost concurrently. And the flow is shown in FIG.
After returning to step 6 of 1 and performing a search, it reaches step 7 and after that, after repeating steps 5, 6 and 7 for each cartridge A as described above, the fifth switch is turned on in step 7. Step 8 when turned on
Leading to.

Then, step 8, that is, the discharging routine of the cartridge A _n of FIG. 16 will be described with reference to FIG. The discharge routine of the cartridge A _n, finally the cartridge A _n loaded is taken out from the cartridge housing part 24, but the discharge and return from the supply section 6 of the roll film carrier 1 to the cartridge housing part 24 is performed Unlike the case of the main routine of FIG. 15, in this case, the front surface portion 3 of the supply unit 6 is
No opening and closing of 8.

In the discharging routine of the cartridge A _n , first, in step 49 of FIG. 16, the upper arm 64 and the lower arm 65 of the holder portion 50 of the discharging mechanism 23 which has been in the standby state have been searched and are used. The last cartridge A _n in the supply section 6 is held by turning on the solenoid 66 (see FIG. 10 (1)). After that, in the next step 50, the holder 50 holding the cartridge A _{n in} this way moves to the end in the J direction by the third motor 57 being driven in the normal rotation, and the step 50 is performed.
Then, the third switch 67 is turned on, and the third motor 57 is stopped in step 52 (see FIG. 10 (1)). Thereafter, in step 53, the holder 50 is driven in the reverse rotation of the fourth motor 60 to face the L direction, and in step 54, the fourth direction is applied.
The switch 68 is turned on, and in step 55 the fourth motor 6
0 stops (see (2) of FIG. 10). Then, the process proceeds to the next step 56, first, the solenoid 66 is turned off to release the holding of the cartridge A _n , and the discharging mechanism 2
Locking 3 extraction plate 51 is released, extraction plate 51 is moved in the direction P while holding the cartridge A _n, returns the cartridge A _n in the cartridge receiving section 24. Then, the cartridge A _n is returned to the end of each cartridge A that has already been used and returned in the cartridge storage portion 24, and is the reverse of the cartridge A that was stored in the previously unused state. It is returned in the direction (see (2) and (3) in FIG. 10).

As described above, the cartridge loader 2
The search by the roll film carrier 1 is completed for all the cartridges A stored in the one cartridge storage section 24. Now, in the roll film carrier 1 and the cartridge loader 21, the replacement time of each cartridge A is shortened as follows.
Secondly, jam handling is also facilitated, and thirdly, whether each cartridge A has been used or not can be easily distinguished.

First, the replacement time of each cartridge A is shortened. That is, the roll film carrier 1 of the leader printer or the like, and the cartridge loader 21 attached to the leader printer or the like.
In, the loading path B and the discharging path C of the cartridge A of the microfilm F are individually formed without overlapping. In the illustrated example, the loading path B starts from the D and E directions and starts from F and
The G direction and the I and H directions are traced (see FIG. 1), and the discharge path C is traced in the K and J directions, the M and L directions, and then the N and P directions (see FIG. 2). That is, this cartridge loader 2
1, the loading path B from the cartridge storage section 24 to the supply section 6 by the loading mechanism 22 that also incorporates the front section 38 of the supply section 6 on the roll film carrier 1 side;
The discharge path C from the supply section 6 to the cartridge storage section 24 by the discharge mechanism 23 is formed so as to individually follow a completely different path. Then, in the roll film carrier 1 and the cartridge loader 21, there are a discharge of the cartridge A which has been used after the search and copying are finished, and a loading of a new cartridge A which is next searched and copied. , Almost simultaneously. Therefore,
The replacement time of the cartridge A is shortened, and the cartridge A
Will be discharged and loaded quickly.

Second, jam handling is also facilitated. That is, in the roll film carrier 1, in addition to this, when a jam of the microfilm F further occurs, the jam processing is easily performed by opening the rotatable front surface portion 38 of the supply unit 6.

Thirdly, whether or not each cartridge A has been used can be easily distinguished. That is, in this cartridge loader 21, the cartridge A of the microfilm F is loaded into the cartridge storage unit 2 by the loading mechanism 22.
4 is loaded into the supply unit 6 of the roll film carrier 1, and after that, the discharge mechanism 23 returns the roll film carrier 1 to the cartridge storage unit 24 from the supply unit 6. The cartridges A accommodated in the cartridge accommodating portion 24 have not been subjected to processing such as retrieval and copying, and the orientation of the cartridges A to be loaded in the supply portion 6 from now on and retrieval, The orientation of the cartridge A returned after the processing such as copying has been completed is different. In the illustrated example, the directions of the cartridges A are opposite to each other. Therefore, it is possible to easily distinguish whether or not each cartridge A has already been searched, copied, etc., that is, whether or not it has been used only by the orientation of the cartridge A.
You will be able to determine. And this is the fifth in the illustrated example.
This can be easily achieved by only providing the switch 79 or the like, and when returning the cartridge A to the cartridge storage portion 24 by the discharging mechanism 23, by setting this to a direction different from the original direction. Further, this enables quick retrieval and copying of the microfilm F without any trouble.
