Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a cartridge loader attached to 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.

Microfilms are generally stored in large quantities for use. When using a microfilm, it is required to quickly search for a desired image from a large amount of microfilm, copy the image, or the like. When searching or copying a microfilm in a reader printer or the like, conventionally, a cartridge containing the microfilm is sequentially and manually loaded into a roll film carrier of the reader printer and used cartridge. Had been manually ejected from the reader printer. That is,
Every time a search, a copy or the like is completed for each cartridge, the worker manually ejects the cartridge and loads a new cartridge, that is, replaces the cartridge. For this reason, it has been pointed out that it takes time and effort to replace the cartridge, and it is difficult to quickly search or copy the microfilm.

In order to deal with such a problem, recently,
Cartridge loaders have been developed for automatically loading and unloading cartridges containing microfilm.
This cartridge loader is attached to a reader printer or the like as an auxiliary device, and has a cartridge storage section capable of storing a plurality of cartridges. This 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. Then, the cartridge loader automatically sequentially takes out the cartridges stored in the stacker and loads them into the roll film carrier, and when the microfilm search or copying is completed in the roll film carrier, the used cartridges are removed. It is designed to be taken out from the roll film carrier and returned to the stacker.

FIG. 24 shows a general stacker. As shown in the figure, the stacker 24 is a container having a long box shape, and 10 to 2 cartridges A are provided.
About 0 pieces are stored side by side. Stacker 2
As shown by an arrow, 4 is a direction in which the front surface faces the roll film carrier, and is detachably attached at a predetermined position. Doors 25 and 26 are provided on the left and right ends of the front surface of the stacker 24. Each of the doors 25 and 26 is provided so as to be openable and closable around the shafts 27 and 28, and the door 25 is located on the loading side of the cartridge A, and is opened from the closed position shown in the drawing each time the cartridge A is loaded. Rotate to position. The door 26 is located on the return side of the cartridge A, and when the stacker 24 is mounted at a predetermined position, the protruding portion 29 of the door 26 is pushed by a stopper (not shown) to move from the closed position to the open position. Turn to. The door 26 holds this open position while the stacker 24 is attached to the mounting table, and a return port for the cartridge A to be returned to the stacker 24 is formed.

A cutout groove 30 is formed in the longitudinal direction on the lower surface of the stacker 24. The cutout groove 30 is formed.
Serves as a passage through which the moving claw portion 96 (see FIG. 26) moves. The moving claw portion 96 sequentially moves the cartridge A before being loaded into the roll film carrier or the cartridge A after being discharged in the stacker 24. By moving the moving claw portion 96, the cartridge A group stored in the stacker 24 moves toward the side surface of the stacker 24 on the loading side, and the cartridge before loading on the roll film carrier becomes
It moves sequentially with other cartridges to a predetermined set position corresponding to the door 25. A long opening 32 is formed on the side surface of the stacker 24 on the loading side, and the long opening 32 functions as a passage through which the set rod 33 (see FIG. 26) moves. The set rod 33 is for sequentially taking out the cartridge A, which has been moved to the set position, from the stacker 24.

An ANSI standard type cartridge A is shown in FIG. The microfilm F is wound around the reel 4 for rewinding in a roll shape, and the reel 4 for rewinding is rotatably supported by the cartridge A in a detachable manner. When each cartridge A is initially stored in the stacker 24, as shown in FIG. 26A, each cartridge A has a spine label side 77 (see FIG. 25) facing the back side shown in FIG. 24 and an opening side 78. (Fig. 2
5) is stored in the stacker 24 in a state of facing the front side (roll film carrier side) shown in FIG. Then, as shown in FIG. 26B, the cartridge A after being returned to the stacker 24 is in the reverse state, that is, the spine label side 77 faces the roll film carrier side, and the opening side 78 in FIG. It is adapted to be stored in the stacker 24 in a state of facing the back side as shown.

[0008]

As shown in FIG. 25, many ANSI standard type cartridges A are inclined by 1 to 2 ° with respect to the floor for manufacturing reasons.
Therefore, as shown in FIG. 26A, when the cartridges A are viewed from the back side of FIG. 24, the cartridges A initially stored in the stacker 24 are slightly inclined to the left.

The cartridge A which has been searched by the roll film carrier is returned to the stacker 24 in the direction opposite to the original direction of the cartridge A, as shown in FIG. That is, each cartridge A returned in the stacker 24 is slightly tilted to the right. For this reason,
As the cartridge An to be loaded and searched last approaches the set position, the last cartridge An or the like may be sandwiched between the first cartridge A1 and the side surface of the stacker 24 on the loading side at the set position.

As a result, when the cartridge An moved to the set position is taken out from the stacker 24, the cartridge An to be taken out is caught by the side surface of the cartridge A1 on the pushing side or the side surface on the loading side of the stacker 24, and a large load is applied to the set rod 33. Has the disadvantage that the probability of a transport error increases.

Further, as shown in FIG. 27, when x number of cartridges A having a capacity smaller than N is accommodated in the stacker 24 capable of accommodating a maximum of N cartridges A, the following is performed. Problems also arise. First, FIG.
As shown in (1), the moving claw 96 reciprocates along the direction of the set position, so that the cartridge A1 initially loaded in the roll film carrier moves to the set position. When the search or copying of the first cartridge A1 is completed, the cartridge A1 is returned to the stacker 24 in the reverse direction as shown in FIG.
Then, in order to move the second cartridge A2 to the set position, the moving claw portion 96 starts moving toward the set position. In this case, when the number (x) of the cartridges A stored in the stacker 24 is small, there is a space between the cartridges Ax and the cartridges A1, and the moving claw portion 96 causes the cartridges A1 to abut on the cartridges Ax. Up to, only one cartridge A1 is moved. Moving claw 96
A surface including a portion that presses the cartridge A is orthogonal to the moving direction of the moving claw portion 96. Therefore, as shown in FIG. 25, the cartridge A1 is pushed along the thin width direction of the cartridge A1 and in the direction in which the cartridge A1 is originally inclined as shown by the arrow W. When the cartridge A is pushed along the W direction, the cartridge A easily falls, and the returned cartridge A1 is tilted rightward as shown in FIG.
When only 1 is pushed toward the cartridge Ax, the cartridge A1 may be inclined so as to lean on the cartridge Ax and a transport error may occur. Further, when the number (x) of the cartridges A stored in the stacker 24 is smaller and the distance between the cartridges Ax and the cartridge A1 is larger than the height dimension of the cartridge A, the cartridge A1 is placed on the bottom of the stacker 24. There is a problem that it falls completely and a transport error occurs.

Therefore, according to the present invention, when the cartridge moved to the set position is prevented from being caught on the side surface of the cartridge on the pushing side or the side surface on the loading side of the stacker, mis-feeding is eliminated, and further, when the cartridge is moved in the stacker. Another object of the present invention is to provide a cartridge loader capable of preventing the cartridge from tipping over or tilting.

[0013]

SUMMARY OF THE INVENTION To achieve the above object, the present invention is a cartridge which can be attached to an image projection apparatus for projecting an image of a microfilm and can accommodate a plurality of cartridges containing the microfilm. In a cartridge loader having a storage unit, a loading unit that guides the cartridge stored in the cartridge storage unit to a film carrier of the image projection apparatus,
Ejection means for returning the cartridge loaded in the film carrier from the film carrier to the cartridge accommodating section, and a cartridge before being loaded in the film carrier or a cartridge after being ejected in the cartridge accommodating section in order. A moving means for moving the cartridge, and the moving means presses the cartridge so that the cartridge tilts in an oblique direction and moves in parallel. Further, the moving means has a pressing portion for pressing the cartridge and a driving portion for moving the pressing portion, and the pressing portion is
A cartridge loader in which a surface of the pressing portion including a portion for pressing the cartridge is inclined with respect to a moving direction of the pressing portion by the driving portion.

Further, in a cartridge loader which is attached to an image projection device for projecting an image of a microfilm, and which has a cartridge accommodating portion capable of accommodating a plurality of cartridges accommodating the microfilm,
The accommodating portion of the cartridge accommodating portion is provided with a predetermined set position, and loading means for guiding the cartridge at the set position to the film carrier of the image projection apparatus, and the cartridge loaded in the film carrier from the film carrier. The cartridge storage unit has a discharging unit and a moving unit for sequentially moving the cartridge before loading into the film carrier together with other cartridges to the set position. The cartridge loader is characterized in that a protrusion is provided at the bottom of the boundary between the position and the portion for accommodating the other cartridge.

[0015]

The cartridge accommodated in the cartridge accommodating portion is guided to the film carrier of the image projection apparatus by the loading means, and the cartridge loaded in the film carrier is returned from the film carrier to the cartridge accommodating portion by the ejecting means. It Since the moving means for sequentially moving the cartridge before loading or the cartridge after being discharged to the film carrier in the cartridge housing portion presses the cartridge so that the cartridge tilts diagonally and moves in parallel, The cartridge to be guided to the film carrier by the loading means does not get caught on the side of the cartridge on the pushing side or the cartridge housing portion. Further, the cartridge which is inclined and moves in parallel is guided along the cartridge housing portion.

To move the cartridge in parallel while tilting it in an oblique direction, only the surface of the pressing portion of the moving means including the portion for pressing the cartridge is inclined with respect to the moving direction of the pressing portion by the driving portion of the moving means. Will be realized.

Further, even if a protrusion is provided on the bottom of the boundary between the set position of the cartridge housing portion and the portion for housing another cartridge, the cartridge to be guided to the film carrier by the loading means pushes the cartridge or the cartridge housing. It will not get caught on the side of the part.

A take-out claw 71 bent at a right angle is provided at the tip of the take-out plate 51. When the take-out plate 51 is located at the end in the N direction, the take-out plate 51 is located at a position corresponding to the upper and lower arms 64, 65 and the like in the holder part 50 facing the L direction at the end position in the J direction. When the takeout plate 51 is located at the end in the P direction, the takeout plate 51 is located at a position corresponding to the return port formed by opening the door 26 of the stacker 24.

The take-out plate 51 and the arm holding plate 58 of the holder section 50 are connected by a wire rod 73 via a pulley 72. Lock claw 7 formed on the take-out plate 51
4 can be engaged with a bent piece of a guide plate 76 that guides the slide movement of the take-out plate 51 along the N-P direction. A tension spring 75 is interposed between the take-out plate 51 and a fixed wall (not shown) to urge a spring force to move the take-out plate 51 in the P direction. Also, the arm holding plate 5
The protrusion 69 of 8 pushes the take-out plate 51 when the holder 50 rotates in the L direction. Then, the take-out plate 51 and the holder portion 50 are interlocked under the following predetermined movements.

First, when the holder portion 50 moves to the end in the K direction and is in the standby state, the take-out plate 51 is located at the end in the N direction, and the tension spring 75 directs it in the P direction. At the same time as being biased, the lock claw 74 is locked by being locked to the bent piece of the guide plate 76 (state of FIG. 4).

Next, the holder portion 50 in the standby state
Holds the used cartridge A by the upper and lower arms 64 and 65, then moves to the end in the J direction and rotates in the L direction. Next, when the solenoid 66 is turned off and the holding of the cartridge A is released, the take-out plate 51 operates as follows. When the holder part 50 rotates in the L direction, the projection 69 of the arm holding plate 58 pushes the take-out plate 51, the lock claw 74 and the bent piece of the guide plate 76 are released, and the take-out plate is taken out. The lock of the plate 51 is released. The unlocked take-out plate 51 moves along the guide plate 76 in the P direction by the spring force of the tension spring 75 while holding the cartridge A by the take-out claw 71.
Then, the cartridge A is returned to the rearmost position in the stacker 24 through the return opening formed by opening the door 26.

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. Figure 8
FIG. 3 is a perspective view showing a state where the reel 4 is taken out from the cartridge A, FIG. 1A shows an ANSI standard type, and FIG. 2B shows a 3M type. Of course, this embodiment is applicable to both types.
When each cartridge A is initially stored in the stacker 24, each cartridge A has a back label side 77 facing the front side shown in FIG. 3 and an opening side 78 facing the supply section 6 side of the roll film carrier 1. Stacker 24
It is stored inside. After being returned to the stacker 24, the cartridge A is stored in the stacker 24 in the reverse state, that is, with the spine label side 77 facing the supply section 6 side and the opening side 78 facing the front side. .

The direction of the cartridge A in the stacker 24 is reversed as described above.
Is moved and returned as follows. That is, the used cartridge A is held from the spine label side 77 by the upper and lower arms 64 and 65 of the holder portion 50 of the ejection mechanism 23 and rotated from the M direction to the L direction, and at the same time, the taken-out plate 51 With the take-out claw 71, J
At the end of the direction, the spine label side 77 is the rear side as it is and the opening side 7
This is because 8 is moved toward the front side in the stacker 24 and returned.

The cartridge A to be loaded next is
In order to detect the orientation of the back label 7 of the cartridge A at a position facing the door 25 of the stacker 24.
A switch that is turned off at 7 and turned on at the opening side 78 may be provided. When this switch is turned on, stacker 2
It is detected that all the cartridges currently stored in 4 have been used.

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, the loading path B from the stacker 24 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 are different paths without overlapping. It is designed to be traced.

FIG. 13 is a schematic block diagram showing the overall control system of the reader printer including the roll film carrier 1, the cartridge loader 21, and the like. Operation panel 84
The search device provided with is connected to the reader printer, the roll film carrier 1, and the cartridge loader 21 through the interface, and further, is connected to the microcomputer M.
It is connected to C. Search information of image information to be searched or copied is input by an operator operating the operation panel 84. Then, the Mycoro computer MC outputs a control signal for loading and unloading the cartridge A to the cartridge loader 21 based on the input search information, and selects a target from among the microfilms F accommodated in the cartridge A. A control signal for retrieving the image information to be reproduced is output to the roll film carrier 1, and a control signal for copying the image information for which retrieval has been completed is output to the reader printer.

FIG. 14 is a block diagram of control means for controlling the operation of the cartridge loader 21. The microcomputer MC as a control means is provided with the cartridge A by the loading mechanism 22 of the cartridge loader 21.
Loading operation of the cartridge and the cartridge A by the discharge mechanism 23
Control the return behavior of. C of microcomputer MC
Signals from the first to fifth switches 37, 42, 67, 68, 79 and the like are input to the PU via the input / output port T. A control signal corresponding to the input signal is output from the microcomputer MC to the first to fifth motors 36, 41, 57, 60, the solenoid 66, etc. through the input / output port T, respectively.

In the cartridge loader 21 of this embodiment,
Before the cartridge A loaded in the supply unit 6 can be taken out, the holder unit 50 of the ejection mechanism 23 holds the cartridge A in advance. In other words, from the completion of loading into the supply section 6,
The cartridge A being loaded is held at an appropriate timing until the search or the like is completed and the rewinding of the film F is completed. For example, the holder unit 50 holds the cartridge A when searching or copying the microfilm F contained in the loaded cartridge A.

In the roll film carrier 1, when the image information recorded on the microfilm F is searched or copied, vertical scanning for correcting the vertical shift of the image is possible. When this vertical scan function is used, the cartridge loader 2
Since the relative position between the roll film carrier 1 and the roll film carrier 1 is displaced, it is necessary to correct this deviation when replacing the cartridge A loaded in the roll film carrier 1. Therefore, the roll film carrier 1 is moved to the neutral position while the micro film F is being rewound after the search of the cartridge A is completed. The neutral position of the roll film carrier 1 means a position where the center of the optical axis of the reader printer is at the center of the microfilm F. The cartridge loader 21 is installed separately from the roll film carrier 1 in a reader printer or the like, but the mounting position of the cartridge loader 21 is fixed at a position where it normally operates when the roll film carrier 1 is in the neutral position. Has been done.

The microcomputer MC of this embodiment is
Until the first cartridge A is set on the set rod 33, the moving amount of the moving claw portion 31 moved from the initial position is measured, and based on this moving amount, the amount of the cartridge A stored in the stacker 24 is changed. It is designed to recognize the number of pieces. The moving claw portion 31 moves from the initial position where the fifth switch 79 is on until the entire cartridge A group moves and the first cartridge 1 is set on the set rod 33, that is, the first switch 37 is turned on. Move until turned on. By measuring the moving amount of the moving claw portion 31 by the CPU or the counter of the microcomputer MC, the number of the cartridges A stored in the cartridge container 24 can be easily recognized. 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, if the initial movement amount of the set rod 33 is Rmm plus 25.4 mm, the number of cartridges A stored in the stacker 24 is recognized as "N minus 1". Also, the initial movement amount of the set rod 33 is Rmm plus (25.4 mm
X2), the number of the cartridges A stored in the cartridge container 24 is recognized as "N minus 2". And microfilm MC
Determines that the number of exchanges required to exchange all the cartridges A is the number of the cartridges A minus 1, based on the number of the recognized cartridges A.

Next, the operation of this embodiment will be described. FIG. 15 shows the operation of the cartridge loader 21 of this embodiment.
~ It will be described with reference to the operation state diagram shown in Fig. 17 and the flowcharts shown in Figs. 18 to 23. Incidentally, FIG.
FIG. 17 is an operation state diagram showing the loading operation, the replacement operation, and the ejection operation of the cartridge A, respectively. Each drawing (1) shows the initial stage of each operation, and each drawing (2) shows the movement stage of each operation. , Each figure (3) shows the end stage of each operation.

First, the outline of the operation will be described with reference to FIG. When the start switch is turned on in step S1, initialization is performed in step S2. After the initial settings are made, the first loading of the cartridge A1 into the roll film carrier 1 is performed in step S3, and the search for the microfilm F contained in the cartridge A1 is performed in step S4. Cartridge A
When the search for the microfilm F in 1 is completed, the first cartridge A1 is ejected and the second cartridge A2 is loaded, that is, the cartridge A is replaced in step S5. Then, step S6
At, it is determined whether the search or the like has been completed for all the cartridges A currently stored in the stacker 24. This determination is made by the stacker 2 as described above.
This is performed by first recognizing the number of the cartridges A accommodated in the cartridge 4, and based on this recognition, determining whether or not the search for the microfilm F of the last cartridge An is completed. If not, the process returns to step S4, and steps S4 to S6 are repeated again, whereby each cartridge A after the second cartridge A2
Are sequentially searched, discharged, and loaded. When it is determined in step S6 that all the searches have been completed, in step S7, the last cartridge An is discharged from the roll film carrier 1 and returned to the stacker 24. Hereinafter, each routine will be described.

Initial Setting As shown in FIG. 19, in this initial setting 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 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 (see FIG. 3).
If the determination in step S10 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 (S10). 2 Motor 41 stops (S1
2). In the next step S13, it is determined whether or not the third switch 67 is on, that is, the holder unit 50 is at the initial position J.
It is determined whether or not it is located at the end of the direction (see FIG. 4).
If the determination in step S13 is NO, the third motor 57 is driven to rotate forward (S14), the third switch 67 is turned on, and it is determined that the holder unit 50 has moved to the initial position (S13). The motor 57 stops (S1
5). In the next step S16, it is determined whether or not the fourth switch 68 is on, that is, whether or not the holder portion 50 faces the L direction which is the initial direction (see FIG. 4).
If the determination in step S16 is NO, the fourth motor 60 is driven in reverse rotation (S17), the fourth switch 68 is turned on, and it is determined that the holder portion 50 is oriented in the L direction (S16). The motor 60 is stopped (S18). Further, in step S19, it is determined whether or not the fifth switch 79 is on, that is, whether or not the moving claw portion 31 of the loading mechanism 22 is located at the end in the D direction which is the initial position (see FIG. 3). . If the determination in step S19 is NO, the first motor 36 is driven in reverse rotation (S20), the fifth switch 79 is turned on, and it is determined that the moving claw portion 31 has moved to the initial position (S19). 1 Motor 36 stops (S2
1). Thus, in the initial setting routine, the carrier 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, respectively, as shown in FIG.

Loading of Cartridge A As shown in FIG. 20, in the cartridge loading routine, loading of the first cartridge A1 by the loading mechanism 22 is performed. In step S25, the moving claw portion 31
Is moved in the E direction from the initial position shown in FIG. 15 (1) when the first motor 36 is driven to rotate normally. The movement amount Smm of the moving claw portion 31 is measured by the CPU or the counter of the microcomputer MC and is temporarily stored in the RAM (S26). Moving claw part 31
A group of the cartridges A in the stacker 24 also moves in the E direction as the first cartridge A1 is set on the set rod 33.
Is turned on (S27). Then, the first motor 36 reverses and is driven in reverse rotation, and the moving claw portion 31 reverses and moves in the D direction (S28). When the fifth switch 79 is turned on, the moving claw portion 31 has returned to the initial position and stops its movement (S29, S30).

Next, in step S31, the front surface portion 38 of the carrier is moved 90 degrees forward from the closed position which is the initial position shown in FIG. 15 (1) by the second motor 41 being driven in the reverse rotation direction. Turned towards I
The open position is along the direction (see FIG. 15 (2)). 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 set rod 33 moves from the stacker 24 side toward the carrier front face portion 38 side. As a result, as shown in FIG. 15B, the cartridge A1 is held by the carrier front surface portion 38 (S32). After that, the second motor 41 is driven to rotate forward, and the carrier front surface portion 38
Rotates in the H direction while holding the cartridge A1 (S33). With this rotation, the second switch 42
Is turned on, the second motor 41 is stopped (S34,
S35). As a result, the cartridge A1 is
As shown in (3), the roll film carrier 1 is positioned and loaded in the supply section 6. At the same time, the set rod 33 moves to the cartridge container 24 side and is locked again. Then, in the next step S36, 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. As described above, 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 the cartridge A1 is loaded.

When the cartridge A group before being loaded into the roll film carrier 1 is moved in the stacker 24, the cartridge A group has the inclined surface 3 of the moving claw portion 31.
By 1a, it is pressed in a direction inclined with respect to the D-E direction and inclined in an oblique direction, and moves in parallel in the stacker 24 while being guided by the front and rear side surfaces of the stacker 24. For this reason, the contact between the cartridge A1 that has moved to the set position and the loading side surface of the stacker 24 becomes small, and the first cartridge A1 may be sandwiched between the second cartridge A2 and the loading side surface of the stacker 24. It disappears (see FIG. 9 (1)). As a result, steps S31 and S
When the cartridge A1 moved to the set position by 32 is taken out from the stacker 24 by the set rod 33, the side surface of the cartridge A2 on the pushing side and the side surface on the loading side of the stacker 24 are not caught (see FIG. 9).
(See (2)), the cartridge A1 can be taken out smoothly.

Searching Operation As shown in FIG. 21, in this searching routine, the cartridge A loaded in the supply section 6 and being searched or copied is held. In step S40, the holder unit 50 of the ejection mechanism 23 faces the M direction by the forward rotation driving of the fourth motor 60, and moves in the K direction by the reverse rotation driving of the third motor 57 in step S41. Move to the edge. Furthermore, solenoid 6
6 is turned on, and the upper arm 64 and the lower arm 65 of the holder unit 50 hold the cartridge A already loaded in the supply unit 6 (S42). Holder part 50
Waits while holding the loaded cartridge A. Along with the movement of the holder 50, the discharging mechanism 23
The take-out plate 51 is moved to the end in the N direction and locked (see FIG. 15 (3)).

In the roll film carrier 1, while the microfilm F is being conveyed between the rewinding reel 4 and the winding reel 5, desired image information is manually or automatically searched.

While the roll film carrier 1 is being searched, in the cartridge loader 21, in step S43, the first motor 36 is driven to rotate in the forward direction, 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 the length plus 5.4 mm. By the movement of the moving claw portion 31, as shown in FIG. 16A, the cartridge A2 to be loaded next is set on the set rod 33. When the moving claw portion 31 moves in the E direction by the predetermined length, 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 ( S44). When the fifth switch 79 is turned on, the moving claw portion 31 has returned to the initial position and stops its movement (S46). The operation of the moving claw portion 31 returning to the initial position prevents the cartridge A2 set on the setting rod 33 from being left sandwiched between the moving claw portion 31 and the first switch 37. 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 cartridge 50 being loaded is held by the holder portion 50 of the ejection mechanism 23 while the microfilm F is being searched, and the moving claw portion 31 of the loading mechanism 22 is initialized. The cartridge A is reciprocated from the position and the next cartridge A is set on the set rod 33.

The cartridge A after being returned to the roll film carrier 1 moves in step S43. In this case as well, the returned cartridge A is moved by the inclined surface 31a of the moving claw portion 31 in the same manner as described above. It tilts in an oblique direction and moves in parallel in the stacker 24 while being guided by the front and rear side surfaces of the stacker 24. Further, since the cartridge A is pressed in a direction inclined with respect to the D-E direction in which the moving claw portion 31 moves, and the movement of the cartridge A is performed along the front and rear side surfaces of the stacker 24, the maximum capacity N
Stacker 24 with a smaller number of cartridges A than 24
When the cartridge A is stored in the
Even if the cartridge A is pushed and moved by 1, the cartridge A will not fall down.

Replacement of Cartridge A As shown in FIG. 22, in the cartridge replacement routine,
The ejection of the cartridge A1 loaded in the supply unit 6 of the roll film carrier 1 and the loading of the next new cartridge A2 are performed in parallel at substantially the same time.
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, rewinding is performed and the microfilm F is
All are rewound on the rewinding reel 4 (S50). When the vertical scan function is used in the roll film carrier 1, the roll film carrier 1 is moved to the neutral position during step S50.
Next, the carrier front surface portion 38 is rotated 90 degrees in the I direction from the closed position to the open position (S51), the set rod 33 is unlocked, and the next new cartridge A2 is held on the carrier front surface portion 38. (Fig. 16 (2)
reference). Now, the flow is divided into a flow after step S53 and a flow after step S54, and the process is returned after waiting for the end of both of these two parallel processes. In addition, when the vertical scan function is used, Microfilm F
The misalignment of the roll film carrier 1 is corrected during the rewinding of
1 can be returned smoothly and the cartridge A2 can be loaded smoothly, the time required for exchanging the cartridge A can be shortened, and the retrieval or copying of the microfilm F can be performed quickly.

First, the processing after step S53 will be described. The holder portion 50 of the ejection mechanism 23 that was on standby while holding the cartridge A1 in the previous step S42.
Is driven by the third motor 57 being driven forward,
It moves toward the direction (S53). As shown in FIG. 16 (2), when the holder part 50 moves to the end in the J direction, the third switch 67 is turned on (S55), and the third motor 5
7 is stopped and the holder 50 stops moving (S5).
6). Next, the holder 50 is rotated in the L direction by the reverse rotation of the fourth motor 60 (S57). When the fourth switch 68 is turned on, the fourth motor 60 is stopped (S58, S59). Holder part 5
With the rotation of 0, the ejection plate 51 of the ejection mechanism 23 is unlocked, and the solenoid 66 is turned off to release the holding of the cartridge A. As a result, the take-out plate 51 moves in the P direction while holding the cartridge A1, and the cartridge A1 is returned to the stacker 24 (S60). At this time, as shown in FIG. 16C, the cartridge A1 ejected from the supply section 6 is returned to the rearmost side of each cartridge A stored in the stacker 24. Further, the cartridge A1 is returned to the stacker 24 in the direction opposite to the storage direction of the unused cartridge A which has not been searched yet.

Next, the processing after step S54 which is performed in parallel with the above-described processing of the holder 50 will be described. The front surface 38 of the carrier which holds the next cartridge A2 in the previous step S52 and is located at the open position rotates in the H direction while holding the cartridge A2 in steps S54, S61 and S62. As a result, the cartridge A2, as shown in FIG.
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 (S63).

In this way, the flow after step S53 and the flow after step S54 are processed in parallel, and after waiting for them to end together, the flow returns. Incidentally, when searching for the microfilm F in the newly loaded cartridge A2, etc.,
In steps S40 to S42 described above, the take-out plate 51 is set to N.
The holder unit 50 is moved to the end in the direction and locked, and the holder unit 50 stands by while holding the cartridge A2.

Since the holder unit 50 is on standby while holding the cartridge A (S42), at the same time as the rewinding of the microfilm F is completed, the supply unit 6
It is possible to immediately perform the discharging operation of taking out the cartridge A loaded in the above and the loading operation of loading the next new cartridge A in the supply section 6. Therefore, the time required to replace the cartridge A can be shortened, and the microfilm F can be searched and copied quickly. There is also an advantage that the vibration of the cartridge A during loading is suppressed.

When the cartridge A is replaced, as described above, the cartridge A to be taken out by the set rod 33 does not get caught on the side surface of the cartridge A on the pushing side or the side surface on the loading side of the stacker 24, and a misfeed occurs. There is no such thing.

Discharging Cartridge A As shown in FIG. 23, in the cartridge discharging routine,
The last loaded cartridge An is discharged from the supply unit 6 and returned to the cartridge container 24. The operation in this routine is shown in FIG.
Unlike the operation in the replacement routine of the cartridge A shown in (4), the front surface 38 of the carrier is not opened or closed. In steps S65 to S67, the same operations as steps S53, S55 and S56 shown in FIG. 22 are performed.
That is, the cartridge A loaded in the supply unit 6
The holder part 50, which was on standby while holding, moves in the J direction and stops at the end in the J direction (FIG. 17 (1)).
reference). In the next steps S68 to S70, FIG.
The same operation as steps S57 to S59 in 2 is performed, the holder unit 50 rotates in the L direction, and stops when facing the L direction (see FIG. 17 (2)). After that, step S
Proceeding to 71, the lock of the takeout plate 51 of the ejection mechanism 23 is released, and the holding of the cartridge A is released,
The cartridge A is returned to the stacker 24. This cartridge A is also returned to the end of each cartridge A already returned in the stacker 24, and is returned in the direction opposite to the storage direction when not in use (FIG. 17).
(3)).

As described above, in the cartridge loader 21 of this embodiment, each cartridge A has the moving claw portion 3.
The inclined surface 31a of No. 1 pushes the movable claw portion 31 in a direction inclined with respect to the moving direction of the movable claw portion 31 and inclines in a slightly oblique direction, and is guided to the front and rear side surfaces of the stacker 24 while being guided by the stacker 2
Move in parallel in 4. Therefore, the contact between the cartridge A moved to the set position and the loading side surface of the stacker 24 becomes small, and the cartridge A to be taken out which has been moved to the set position is pushed to the side surface of the cartridge A on the pushing side or the loading side surface of the stacker 24. It will not be caught and will not cause a transport error. Further, the cartridge A is pressed in a direction inclined with respect to the moving direction of the moving claw portion 31 and
Are moved along the front and rear side surfaces of the stacker 24, the number of the cartridges A smaller than the maximum capacity N
When one of the cartridges A is stored in the stacker 24, even if only one cartridge A is pushed and moved by the moving claw portion 31, the cartridge A may fall down so as to lean on another cartridge A or may completely fall over. As a result, the number of conveyance errors is reduced and the number of conveyance errors is significantly reduced.

The shape and the like of the moving claw portion 31 are not limited to those described above, and may be, for example, a moving claw portion 31 'having a shape as shown in FIG. The moving claw portion 31 ′ has a body portion 92.
9 extending from the left and right sides of the arm toward the E direction (see FIG. 3)
The lengths of 3 and 94 are different. According to this structure, as shown by an imaginary line, the surface 31′a including the portion that presses the cartridge A is not orthogonal to the moving direction of the moving claw portion 31 ′, but is inclined several degrees from the orthogonal surface. Since it is formed so as to have the above-described structure, the same operation and effect as those of the above-described moving claw portion 31 can be obtained.

In order to move the cartridge A in a slanting direction, the surfaces 31a and 31'a including the portions of the moving claws 31 and 31 'which press the cartridge A are moved.
Need only be inclined with respect to the moving direction of the moving claw portions 31 and 31 ′, and it is possible to easily and inexpensively realize the reduction of conveyance mistakes.

FIG. 11 shows a stacker 2 according to another embodiment.
It is a perspective view which shows 4 '. Incidentally, in this figure, the front side surface of the stacker 24 'is not shown. The illustrated stacker 24 'is formed in substantially the same manner as the above-mentioned stacker 24, but of the bottom portion of the stacker 24', a set position where the loaded cartridge A is set and a portion for accommodating other cartridges. A protrusion 95 is provided at the boundary. As shown in FIG. 12, the protrusion 95 has a height of about 0.5 to 1 at a position, for example, about 25 mm, which is the thickness of one cartridge A from the side of the stacker 24 'on the loading side.
It has a semicircular shape of about mm. This protrusion 95
As a result, as shown in FIG. 12, the unsearched cartridge An at the set position is tilted substantially vertically or rightward when viewed from the back side of FIG. 11, and the cartridge A group on the side pushing the cartridge An stands substantially vertically. Like Therefore, the cartridge A in the set position has less contact with the adjacent cartridge A and the stacker 24 ′, and the cartridge A to be taken out that has moved to the set position has a side surface of the cartridge A on the pushing side or the stacker 24 ′.
It does not get caught on the side of the loading side of
The load on the sheet is reduced, and a mistake in conveyance does not occur. In the case of the stacker 24 'having the projection 95, the moving claw portion may be a general moving claw portion 96 having no inclined surface.

[0072]

As described above, in the cartridge loader of the present invention, the moving means for sequentially moving the cartridge before loading into the film carrier or the cartridge after being discharged in the cartridge housing portion is
Since the cartridge is pushed so as to be inclined and moved in parallel in the oblique direction, the cartridge to be guided to the film carrier by the loading means should be pushed on the pushing side even if the cartridge is slightly inclined for manufacturing reasons. It does not get caught on the side surface of the cartridge or cartridge storage part, the load acting on the loading means does not increase,
There will be no mistakes in transportation. Further, since the cartridges that are inclined and move in parallel are guided along the cartridge storage portion, when one cartridge is stored in the cartridge storage portion, the number of cartridges smaller than the maximum capacity is reduced to one cartridge. Even if the cartridge is pushed and moved by the moving means, there is less risk that the cartridge will fall down so that it leans on another cartridge, or it will completely fall over, and transport errors will be significantly reduced.

In order to move the cartridge in a slanting direction in parallel, the surface of the pressing portion of the moving means including the portion for pressing the cartridge is inclined with respect to the moving direction of the pressing portion by the driving portion of the moving means. Good, it is possible to easily and inexpensively realize the reduction of transport mistakes.

Further, even if a protrusion is provided at the bottom of the boundary between the set position of the cartridge housing portion and the portion for housing another cartridge, the cartridge to be guided to the film carrier by the loading means is also the cartridge on the pushing side. And the side surface of the cartridge housing portion is not caught, the load acting on the loading means does not become large, and a conveyance error does not occur.
