Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is applicable to, for example, a microreader that magnifies and projects an image on a microfilm screen for viewing, a reader printer that also has a copying function, and a device that displays an image on a solid-state image sensor. Manual input of the identification information attached to the loaded microfilm using a microscanner that reads it, or an image projection device such as a microfilm printer that only has the function of copying microfilm images. The present invention relates to an image projection device that facilitates the input of search information by displaying the image near the screen.

Conventional technology Microfilm is used in large quantities in distribution-related and financial-related companies because it is recognized as having legal evidence. In such large-scale users, it is common for microfilms wound in rolls to be stored in dozens of rolls. When performing a search, it is necessary to search for a desired image from among such a large amount of microfilm, so an efficient search is required.

Large-scale users who own large plates of microfilm search for necessary images in the following manner.

First, in the first step, an instruction sheet indicating the cartridge number, frame number, etc. of the microfilm to be searched is outputted from a computer or the like. In the second step, based on this instruction, the designated cartridge is manually taken out from the storage shelf where a huge amount of microfilm, for example dozens of blades, is stored. Each unit is stored in a returnable box along with instructions. This returnable box is carried to an operator who operates an image projection device such as a reader printer. In the third step, the operator takes out the necessary cartridges one by one from the returnable box while referring to the instructions, manually loads them into the image projection device, and searches and copies the image with the desired frame number. Do this. Thereafter, the cartridge after the search is manually removed from the image projection device, returned to the returnable box, and returned to a predetermined position on the storage shelf. After the eel, in the fourth step, copies of the paper are distributed to related parties.

Problems to be Solved by the Invention In this way, when an operator inputs search information,
First, it is necessary to manually search for information by looking at the instructions and checking the label affixed to the back of the loaded cartridge, so each time you input search information, you have to look into the loading section of the cartridge. The user had to look at the label while inputting information, which was cumbersome and inefficient.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an image projection device that allows efficient input of search information.

Means for Solving the Problems To achieve the above object, the present invention provides an image projection device for searching and projecting an image on a microfilm, comprising: an identification information reading means for reading identification information on the microfilm; Search information manual means for manually inputting search information on the microfilm loaded in the microfilm loading section of the projection device, and identification information on the microfilm loaded in the loading section, which is provided near the search information input means. and a retrieval means for retrieving and projecting a desired image from the microfilm based on the retrieval information input from the retrieval information input means.

Operation The image projection apparatus of the present invention configured as described above operates as follows.

The identification information reading means reads the identification information of the microfilm, and the display means displays the identification information of the microfilm loaded in the microfilm loading section of the image projection device. Therefore, the operator can input search information from the search information input means located near the display means while viewing the content displayed on the display means. The search means searches for a desired image based on the search information input from the search information input means and projects it on the screen.

Diagram showing the key layout, 4th
The figure is a schematic diagram of the optical system of the reader printer. In this embodiment, a reader printer will be described as an example of an image projection device.

As shown in FIG. 1, the reader printer is provided with a cartridge loading section 20 into which a cartridge B is loaded. This cartridge loading device A stores microfilm cartridges B taken out from the storage shelf described above in units of about 10 to 20.

On the top surface of each cartridge B, a label is attached with identification information, specifically a bar code, to enable identification from other cartridges. This identification information is read by a code reading sensor provided in the cartridge loading device A, which will be described later. Further, the reader printer is provided with a controller 24 that functions as a search information manual means. The controller 24 inputs frame numbers as search information, inputs various other commands related to the search, and inputs commands to copy searched images. The cartridge B loaded in the cartridge loading section 20 is searched based on the frame number input by the controller 24, and the searched image is projected onto the screen 10 of the reader printer. Note that when a copy command for an image searched by the controller 24 is input, the image is copied, and the paper after copying is discharged to the paper discharge tray 18.

As shown in FIG. 2, the controller 24 includes an operation key part 24A in which various keys are arranged, and a display means for displaying key operations arranged in the operation key part 24A, search status, etc. A display section 24B is provided. As shown in FIG. 3, various keys necessary for searching are arranged in this operation key portion 24A. Keys with numbers 0 to 9 displayed are keys for entering numbers manually, and the enter key is used as a separator for entering numbers or when moving to the next search operation. . The rewind key is a key used to rewind the microfilm, and the keys labeled +l and -1 are keys that mainly command forward one frame or backward one frame. The key with -9- displayed is a key used to feed the microfilm at low speed in the direction of the arrow only while the key is pressed. The execution key is a key used to execute an input command, and the cancel/stop key is a key used to cancel an emergency stop during operation or other manually input key commands. The search key is a key used to search for the target frame of microfilm input using the numeric key, and the print key is a key to copy the searched image. The set key is a key used to set the address of the first frame of microfilm, and is a key used when performing a skip reading search. Finally, the memory key is a key used when performing memory operations. The controller 24 outputs commands inputted by such various key operations.

The optical system of this reader-printer is constructed as shown in FIG. That is, the light from the light source 1 is focused by the condenser lens 2, and the light from the film carrier 3 is condensed by the condenser lens 2.
The image of the microfilm F located between the pressure plate glasses (not shown) is illuminated from below. The image on the microfilm F through which this light has passed is enlarged and projected by a projection lens 4, and reaches a mirror 6 via a prism 5 whose direction is adjusted as necessary.

When this reader printer is in the reader mode, a reader optical path 7 is formed as shown by the broken line in the figure. In this mode, the light is reflected by the stopped mirror 6, and further reflected by the mirrors 8.9 and directed towards the screen 10. As a result, the image on the microfilm F is enlarged and projected onto the screen 10 provided at the upper front of the reader/printer for viewing.

On the other hand, when the reader printer is in the print mode, a printer optical path 11 is formed as shown by the solid line in the figure in place of the reader optical path described above. In this mode, the light is switched for scanning by rotating the mirror 6 by 90° about the incident optical axis and is reflected by the fixed mirrors 12, 13, 14, 15 towards the photoreceptor 16. Therefore, the image on the microfilm F is rotated by the drum-shaped photoreceptor 1 in synchronization with the oscillating scan of the mirror 6 about the axis perpendicular to the optical axis.
6 and subjected to slit projection exposure. Copying is then performed through a known process, the image is fixed between fixing rollers 17, and the paper P after copying is ejected to a paper ejection tray 18 provided at the lower front of the reader printer.

The film transport mechanism 3 provided in the optical system is composed of a take-up reel 19 and a cartridge loading section 20. Cartridge B loaded in the cartridge loading section 20
Inside, a microfilm F is wound around a rewind reel 21. The microfilm F is rotated in forward and reverse directions as appropriate by drive shafts (not shown) connected to the take-up reel 19 and the rewind reel 21, respectively. As a result, the microfilm F is guided along the conveyance path by the guide roller 22 and conveyed forward and backward between the two reels via the pressure plate glass. A sensor 23 for detecting blip marks attached to the microfilm is provided on this conveyance path. It functions as an identification information reading means for reading the identification information on the microfilm.

The cartridge loading device A includes a container 25 and a main body 26, which will be described later. It is composed of a cartridge moving mechanism 27 and the like. The container 25 can accommodate a plurality of arbitrary microfilm cartridges B (see FIG. 1), and can be carried alone. The container 25 is also called a returnable box, and has a shallow box shape with an open top and front surface.

A single long notch groove 29 is formed in the center of the floor surface 28 of the container 25 in the front and rear.
Some of them even reach 0. A detection protrusion 31 is formed on the tip edge of the container 25, and protrusions 32 are formed on the outer surfaces of both side walls.
or is formed. Two protrusions 32 are provided side by side as shown in the figure. The opening 34 is the container 2
The opening 3 is formed only on one side wall 33 of the opening 3.
4 are arranged side by side and are formed, for example, above the protrusion 32 and near the rear wall 30 of the container 25.

For example, about 10 to 20 cartridges B are stored in such a container 25 and are carried together with the container 25. In other words, the eight groups of cartridges are held at their lower portions in the space surrounded by the side walls 33 and the rear wall 30 on the floor surface 28 of the container 25, and are stored in an upright state stacked one on top of the other along the notched long grooves 29. Ru. A microfilm F in the form of a roll film, which is a long film with an image imprinted on each frame, is wound around the rewind reel 21 (see FIG. 4) in the cartridge B.

By the way, cartridges B for this type of microfilm F are generally divided into two types: ANS I standard type and 3M-M type, both of which have their rewind reel 21.
They differ in the connection structure to the drive shaft, the necessity of a reel press, the presence or absence of a leader at the tip of the microfilm F, the feeding method of the microfilm F, etc. However, not only this container 25 but also the main body 26 described later.
The cartridge moving mechanism 27 can also accommodate any type of cartridge B without any structural problems. In other words, this cartridge loading device A is
It can be used with both the NS I standard type cartridge B and the 3M-M type cartridge, and a mixture of both is also possible.

In addition, the above-mentioned film carrier 3. The cartridge loading section 20. The drive shaft and the like are also compatible with any of these types of cartridges B. Note that a known technique is applied to the dual-purpose mechanism in the loading section 20 and the like.

FIG. 7 is an exploded perspective view of the container 25, main body 26, etc., and FIG. 8 is an enlarged perspective view of main parts showing the main body 26 and a container moving mechanism to be described later.

Hereinafter, the configuration of the main body portion 26 will be explained with reference to FIGS. 7 and 8 in addition to the above-mentioned FIGS. 5 and 6.

A container 25 is detachably attached to the main body 26 of the cartridge loading device A, and in the illustrated example,
Two containers 25A and 25B of the same shape are attached. The main body part 26 is fixedly attached to the front side of the reader printer (see FIG. 1), and has a flat upper surface 35 in the shape of a table. In the illustrated example, two containers 25A and 25B are installed side by side on the top surface 35 with their open front sides aligned, and at the beginning of installation, one container 25A contains, for example, about 10 to 20 cartridges B. is the seventh
The container 25B is stored from the direction C, which is the vertical direction of the arrow in the figure, and the other container 25B is empty. Bent rail portions 36 are provided on both edges of the main body portion 26, so that the protrusion 32 on one side of one container 25A and the protrusion 32 on the other side of the other container 25B described above are attached. It has become. That is, the bent upper portions of both rail portions 36 are positioned on the corresponding protrusions 32 and locked so that they cannot be pulled out, and the container 25A.

25B abuts against the corresponding side wall 33 of the container 25A.
, 25B are positioned and held. Note that the two containers 25A and 25B are in a state in which the remaining protrusions 32 on the other side and the - side are in contact with each other. A notch 37 is formed only in the rail portion 36 on the − side.

When attaching the container 25A to the main body 26, use this notch 3.
After inserting the two corresponding protrusions 32 into the container 25 from the direction D, which is the vertical direction of the arrow in FIG.
By moving A to the open front side, that is, in the direction E, which is the vertical direction of the arrow in FIG. etc. will be held in position.

By the way, in the corner part of the upper surface 35 of the main body part 26,
The cartridge loading section 20 of the film carrier 3 described above is located on the open front side of one container 25A, that is, almost facing the stored cartridge B. Cartridge special equipment section 3 shown in FIGS. 5 and 7
8 is disposed adjacent to the cartridge loading section 20 with a dimension corresponding to the thickness of a partition plate to be described later in between. On the cartridge loading section 20, there is a code reading sensor 39A as an identification information detection means for reading the identification information attached to each cartridge B, and on the cartridge special section 38, there is a code reading sensor 39A for reading the identification information attached to each cartridge B. A cartridge detection sensor 39B is attached to each cartridge to detect the presence or absence of the cartridge. Furthermore, an opening 40 for inserting a drive shaft or the like is formed on the side surface of the cartridge loading section 20.

Pressure detection means 41 are incorporated into the main body 26 at positions corresponding to the detection protrusions 31 of the attached containers 25A and 25B (see FIG. 6). This detection means 41 uses, for example, a reflective sensor or the like, and detects attachment and detachment of the containers 25A and 25B. Further, as shown in FIG. 7 etc., containers 25A, 2
Notch longitudinal grooves 42 are formed parallel to each other at positions corresponding to the notch long grooves 29 of 5B. The notched vertical groove 42 is also parallel to the rail part 36, and the notched vertical groove 42 corresponding to one container 25A extends to the cartridge loading part 20 via the cartridge special part 38. An opening 43 formed in the upper surface 35 of the main body section 26 next to the cartridge loading section 20 in FIGS. 5 and 7 is an opening for protruding a stopper, which will be described later.

The container moving mechanism 44 completes the search and copying of each cartridge B stored in one container 25A, stores the 8 groups of cartridges as used in the other container 25B, and removes this container 25B from the main body 26. Activates when removed. When the container moving mechanism 44 operates, it moves one empty container 25A to the position where the other container 25B was attached on the upper surface 35 of the main body 26.

To explain these in detail, as shown in FIGS. 7 and 8, on one side edge of the main body part 26, the above-mentioned rail part 36
The moving member 4 of the container moving mechanism 44 is located above and has a long plate shape.
5 is arranged, and this moving member 45 is equipped with a container 2.
Protrusions 46 are provided at positions facing the openings 34 of 5A, respectively.

The moving member 45 is connected to a drive device (not shown) via a holding member 47, and has a notch mechanism 42 on the upper surface 35 of the main body 26.
along the notch mechanism 48 formed in the direction perpendicular to the seventh
It is capable of reciprocating movement in the C direction, which is the lateral direction indicated by the arrow in the figure. That is, by reciprocating the holding member 47 within the notch mechanism 48, the movable member 45 can reciprocate in the C direction.

As mentioned above, when one container 25A becomes empty and the other container 25B is pulled out and removed in the H direction, which is the vertical direction indicated by the arrow in FIG. 7, and this is detected by the detection means 41,
The drive device is turned on and the moving member 45 is moved in the G direction from its normal position on one side edge of the main body portion 26. by this,
The protrusion 46 of the moving member 45 engages with the opening 34 of the container 25A, moves the container 25A in the G direction on the upper surface 35 of the main body 26 while holding the container 25A, and moves the container 25A to the other container 2 until then.
Move it to the position where 5B was installed.

Thereafter, only the moving member 45 returns to its original permanent position.

In this normal position, the protrusion 46 is at a retracted position where it does not interfere with the engagement of the protrusion 32 into the notch 37 of the rail portion 36.

Therefore, when attaching the container 25A to the main body 26, the attachment of the moving member 45 does not interfere with the operation.

The cartridge moving mechanism 27 sequentially takes up the cartridges B to be used from the containers 25A on the main body 26, guides them to the cartridge loading section 20 attached to the film carrier 3 of the reader printer, and loads them. and,
This cartridge moving mechanism 27 further discharges the used cartridge B and stores it in the other container 25B different from the one container 25A.

More specifically, the cartridge moving mechanism 27 includes a holding plate 49. As shown in FIGS. 6 and 7, the holding plate 49 is connected to a motor 50, which is a driving source, and a pulley 51. One container 25 is connected via a belt 52 and attached via a notched longitudinal groove 42 on one side of the main body 26.
It can protrude upward from the long notched groove 29 of A. Then, by driving the motor 50, it enters into the notched long groove 29 from the initial retracted position slightly outside the notched long groove 29 shown in the figure and is guided therein, in the vertical direction indicated by the arrow in the figure! It is possible to move back and forth in the direction.

When the detection means 41 detects the detection protrusion 31 of the container 25A and detects that the container 25A is attached to the main body 26, the motor 5
0 is driven, the presser plate 49 moves from the initial retracted position, comes into contact with the rear end side of the group of 8 cartridges housed in the container 25A, pushes it in the direction (■), that is, in the direction of the cartridge loading section 20, and loads the cartridge Bi. It stops when the tip side comes into contact with a partition plate 53, which will be described later. Thereafter, as each cartridge B is used, the holding plate 49 intermittently repeats advancing in one direction and retracting slightly, and guides the cartridges B sequentially toward the cartridge loading section 20. and,
When all the cartridges B in the container 25A have been used, or for some reason, all the cartridges B are removed from the container 25.
When taken out from A, the holding plate 49 returns to the initial retracted position. In other words, it returns to the initial retracted position slightly outside the notch long groove 29, that is, outside the container 25A, and the container 25A is moved by the container moving mechanism 44, and another cartridge B is moved.
Evacuate the container so that it does not interfere with the installation of other containers containing it.

The cartridge moving mechanism 27 further includes a partition plate 53. FIG. 9 is a perspective view of the partition plate 53, etc., FIG. 10 is an enlarged front view of the main parts thereof, and FIG. 11 is a plan view thereof.

The partition plate 53 sequentially takes out the cartridges B from the container 25A, guides and loads them into the cartridge loading section 20, and then discharges the used cartridges B. That is, the partition plate 53 is arranged along the cartridge loading section 20, and extends from the initial position facing the cartridge loading section 20 to the width of the cartridge B in the J direction, which is the lateral direction of the arrow in FIGS. The drive device (not shown) allows reciprocating movement between moving positions that have been moved by approximately the corresponding distance. The partition plate 53 has a size slightly longer than the width of the cartridge B, and has a pull-out claw 5 on one side.
4 is provided with a holding claw 55 on the other side. Pull-out claw 54
is rotatably coupled to a pin by a rotating shaft perpendicular to one side of the partition plate 53. And the pull-out claw 54 is
The partition plate 53 is biased by a spring (not shown) in the counterclockwise direction indicated by the arrow in FIG.
By coming into contact with a stopper 56 formed on one end side of the cartridge, it maintains an operating position that is perpendicular to the partition plate 53 and protrudes toward the cartridge loading section 20 as shown in the figure.

The pull-out claw 54 functions to hook one side of the used cartridge B in the operating position and move it out of the cartridge loading section 20 under pressure. In addition, the pull-out claw 54 normally assumes an operating position, or when each cartridge B is loaded, it rotates clockwise in the opposite direction against the biasing force of the spring by contacting the loaded cartridge B and separates the partition. It does not protrude from the plate 53 and temporarily assumes an inclined retracted position.

The press plate 55 is rotatably pin-coupled to the other side of the partition plate 53 by a vertical rotation shaft.

The presser pawl 55 is biased by a spring (not shown) in the counterclockwise direction indicated by the arrow in FIG. By coming into contact with the member 57, it maintains an operating position in which it forms a right angle to the partition plate 53 and protrudes toward the cartridge loading section 20 as shown in the figure. Presser claw 5
5 functions to hook the other end of the unused cartridge B in the operating position, guide it to the cartridge loading section 20 and move it, and position and hold it in the cartridge loading section 20. In addition, the above spring has - number of cartridges B
The biasing force is set to be enough to hook, move, and position. Further, the presser pawl 55 normally assumes an operating position, but when it comes into contact with the ejected cartridge B when the cartridge B is ejected, it rotates in the opposite direction clockwise against the biasing force of the spring, and the partition It does not protrude from the plate 53 and temporarily assumes an inclined retracted position.

Furthermore, the locking member 57 can be placed in an unlocked position in addition to the above-mentioned locked position. That is,
The locking member 57 is guided in a guide groove 61 formed in a notch on the other side of the partition plate 53, and is attached to be movable up and down in the L direction, which is the up and down direction indicated by the arrow in FIG. Then, it is positioned in the upper position and assumes a lock position, and comes into contact with the presser claw 55 to function as a stopper and maintain this in the operating position. Furthermore, when the locking member 57 is positioned lower and assuming the unlocking position, the locking member 57 that functions as a stopper no longer comes into contact with the presser pawl 55, so that it is further rotated in the direction shown in FIG. 11 due to the biasing force of the spring. and assumes a retracted posture tilted toward the partition plate 53. Therefore, the presser pawl 55 is capable of one retracted position tilted clockwise as described above from the operating position, and also capable of the other retracted position tilted counterclockwise. There is.

FIG. 12 is an enlarged plan view of the main part of the partition plate 53, in which (1) the presser claw 55 is in the operating position, and (2) the presser claw 55 is in the operating position. It shows a state in which the robot is in a retreating position.

The locking member 57 assumes the unlocked position, and the presser claw 55
By taking the retracted position shown in FIG. 12(2), the interruption operation for loading cartridge B becomes possible. In other words,
During the automatic loading operation of the cartridge B from the container 25A into the cartridge loading section 2o which is in a normal state, this is temporarily stopped and the partition plate 53 is inserted instead.
Insert another cartridge B from the other side into the cartridge loading section 2.
Manual interrupt operation to lead to 0 and load becomes possible. FIG. 13 is a schematic plan view for explaining the interrupt operation for loading the cartridge B, and (1)
The figure shows the state before the lock is released, and the figure (2) shows the state during interrupt operation after the lock is released. In other words, by changing the presser pawl 55 from the operating position shown in FIG. 13 (1) to the retracted position shown in FIG. , it becomes possible to insert another cartridge B. In addition, in FIGS. 9 and 10, the inclined surface 57A is formed on the upper surface of the locking member 57 so as to be inclined with respect to the horizontal surface, and when the locking member 57 returns from the unlocked position to the upper locking position, the pressing claw 55 so as to smoothly rotate clockwise in FIG. 11. Figures 9 and 11
The reel holder 58 in the figure is attached to the center of the partition plate 53, and when the aforementioned 3M-M type cartridge B is used, the rewind reel 21 (see FIG. 4) is placed at the center of the drive shaft 59. It works to match.

As shown in FIGS. 5 and 7, the return plate 60 protrudes above the notch longitudinal groove 42 on the other side of the main body 26 and the notch long groove 29 of the other attached container 25A of the same shape. . The return plate 60 is guided by a drive device (not shown) from the normal position shown in the drawing to the long notched groove 29 of the other container 25B, and is movable back and forth in the N direction, which is the vertical direction indicated by the arrow in FIGS. 5 and 7. ing. Used cartridge B
Alternatively, when the cartridge is ejected from the cartridge loading section 20 by the partition plate 53 in the direction of arrow J in FIG. Start moving.

Then, the ejected cartridge B is pushed and moved to the container 2.
After moving to 5B, it returns to its original permanent position again.

The return plate 60 performs such a reciprocating motion each time a cartridge B becomes used and is ejected, and functions to store the used cartridges B into the container 25B one after another.

FIG. 14 is a block diagram of the control system of the image projection apparatus according to the present invention.

This control system can be roughly divided into two parts, as shown by dotted lines in the figure, a controller system 70 which is mainly in charge of retrieval work, and a film loader system 75 which is in charge of transporting microfilm.

The controller system 70 includes an operation key part 24A and a display part 24.
B, a storage section 72, and a CPU 71. Various commands related to the search are outputted from the operation key part 24A. This command is stored in the storage section 72 by the CPU 71. Further, the display section 24B displays information manually input using the operation key section 24A. The film loader system 75 includes a code detection sensor 39A that reads cartridge identification information, a cartridge detection sensor 39B that detects whether or not there is a cartridge B that has not yet been searched, and a code detection sensor 39B that reads cartridge B.
A cartridge loading mechanism 76 for loading into or ejecting from the microfilm F, a film transporting mechanism 3 for transporting the search target frame of the microfilm F to a projection position, and a drive for driving the cartridge loading mechanism 76 and the film transporting mechanism 3. It is composed of a circuit 73 and a CPU 74 that controls the film loader system. CPU71 and CPU
The CPU 74 exchanges signals with each other, and a series of controls related to the search are performed by these two CPUs.

In the image projection apparatus of the present invention, the loading and unloading of the cartridge B are automatically performed. This will be explained with reference to FIG. 15.

FIG. 15(1) shows the standby stage.

The first cartridge B1 on the leading end side, that is, the first cartridge B1 of the group of eight cartridges stored in one container 25A, is stored in one container 25A.
It is located in the cartridge special unit 38 through the open opening A, and is in contact with the partition plate 53 of the cartridge moving mechanism 27. The opposite side of the partition plate 53 is connected to the cartridge loading section 2 of the film carrier 3 of the reader printer.
It is in the initial position opposite to 0. The pull-out pawl 54 and the hold-down pawl 55 of the partition plate 53 are biased by their springs, and both assume an operating position in which they protrude from the partition plate 53 at right angles. When a search start signal is input to the reader printer from this state, the partition plate 53 is moved between the group of cartridges 8 in the container 25A and the cartridge loading section 20, as shown in FIG. 15 (2). The container 25B is retracted from the initial position located near the container 25B, and is retracted to a moving position substantially facing the open front side of the other container 25B that is not interposed therebetween. At the same time, the holding plate 49 operates to move the cartridge 8 group toward the cartridge loading section 20, and the first cartridge B1 moves from the cartridge special section 38 and comes into contact with the cartridge loading section 20.

In the next stage, as shown in Figure 15 (3),
The partition plate 53 starts returning from the movement position to the original initial position. As a result, the cartridge B1 slides between the first cartridge B1 and the second cartridge 82, and comes to be located between them.

At this time, the holding plate 49 is returned to its initial retracted position by the thickness of the partition plate 53, and the second cartridge B2 is positioned in the cartridge special section 38. Furthermore, the pull-out claw 54 of the partition plate 53 comes into contact with the first cartridge B1 during this period, and resists the biasing force of the spring and assumes a retracted position from the operating position, which impedes the sliding of the partition plate 53. There is no such thing.

Thereafter, the loading stage shown in FIG. 15 (4) is reached. That is, as the partition plate 53 further returns toward its initial position, the presser claw 5 assumes the operating position.
5 hooks the other side of the first cartridge B1, and further guides the first cartridge B1, which is already in contact with the cartridge loading section 20, to the cartridge loading section 20. Note that the pull-out claw 54 is released from one side of the first cartridge B1 and returns to the operating position. Then, by returning the partition plate 53 to the initial position, the first cartridge B1 is positioned and held in the cartridge loading section 20 and loaded. When a detection means (not shown) detects that the partition plate 53 has returned to its initial position, the reader printer becomes ready to perform a search.

The second search is for film carrier 3.
After loading the microfilm F from the unwinding reel 21 of the feeder B1, the microfilm F is transported forward and backward between the unwinding reel 21 and the take-up reel 19, and the sensor 23
This is done by detecting the yellow knob mark attached to each frame. When the retrieval is completed in this way and the microfilm F is rewinded to the original rewind reel 21, the stage of ejection and movement as shown in FIG. 15 (5) is reached. That is, the partition plate 53 starts moving from the initial position to the movement position again. Thereafter, the pull-out claw 54 in the operating position hooks one side of the used first cartridge B1 and moves together. Next, a discharge step as shown in FIG. 15(6) is performed. That is, the partition plate 53 is moved from between the cart 9728 group of one container 25A and the cartridge loading section 20 to a moving position where it is almost facing the empty container 25B without being interposed between them, and the first cartridge B1 is also moved. The liquid is discharged through such a partition plate 53 to a position facing another container 25B. At the same time, the holding plate 49 operates again to move the cart 9728 group toward the cartridge loading section 20, and the second cartridge B2 is moved from the previous cartridge special section 38 to the cartridge loading section 20.
It will come into contact with. Further, the stripper 62 protrudes from the opening of the main body portion 26 and is positioned between the first cartridge B1 and the second cartridge B2.

Thereafter, the process moves to the movement stage shown in FIG. 15 (7), and the partition plate 53 starts returning to its original initial position. As a result, the cartridge B2 slides between the second cartridge B2 and the third cartridge 83, and is located between them.

At this time, the holding plate 49 will be returned slightly as described above. When the partition plate 53 returns to its original position, the pull-out claw 54 comes into contact with the second cartridge body B2 in the same manner as described above, and thereby returns to the operating position against the biasing force of the spring. It assumes a retracted position from the position, so that there is no problem in sliding the partition plate 53.

When the partition plate 53 is returned to its original position, the holding claw 55
However, due to the protrusion of the stopper 62, it takes a retracted position from the operating position against the biasing force of the spring, and the ejected first cartridge B1 comes into contact with the partition plate 53. It is designed not to move along with the return movement. Then, (8
) will lead to the next loading stage, etc. as shown in the figure. At this stage, as the partition plate 53 further moves back toward the initial position, the presser claw 55 returns to the operating position, hooks the other side of the second cartridge B2, and guides it to the cartridge loading section 20. Load. The pull-out claw 54 also returns to its operating position. At the same time, the return plate 60 constituting the cartridge moving mechanism 27 operates to guide the used and ejected first cartridge B1 and move it to the back of the empty container 25B. After that, the return plate 60
returns to its original permanent position. Then, for the microfilm F of the second cartridge B2, necessary images are searched and copied in the same manner as described above.

In this way, by repeating each step shown in FIG. 15, all cartridges B stored in one container 25A are sequentially loaded and searched.

Copying and ejection are performed. When all of them are used and stored in the other container 25B, the other container 25B is removed from the main body 26. Then, the container moving mechanism 44 is activated, and the moving member 45 moves the empty container 25A, and until then the other container 25B is moved.
Move this to the position where it was installed. Then, one container 25A performs the function that the other container 25B conventionally performed, that is, stores the used cartridge B. Furthermore, after that, the container 25 that accommodates the unused cartridge B and is attached to the main body 26 will sequentially perform the same function.

Next, a series of search operations performed by the reader printer using the cartridge loading device A will be explained based on the flowchart of FIG. 16.

Before being searched by the reader printer, a plurality of cartridges B of the required microfilm F are taken out from a storage shelf (not shown) and stored in the container 25A constituting the cartridge loading device A. That is, an instruction sheet is outputted from the computer in advance to display the cartridge number, frame number, etc. of the microfilm F containing the necessary image. Based on this instruction, the required cartridge B with a predetermined cartridge number is selected and taken out from a huge amount of storage space such as a storage shelf, for example, on the side of several dozen blades. Approximately 20 pieces are stored in the container 25A together with instructions. The eight groups of cartridges are stored vertically on the floor surface 28 of the container 25A and stacked one on top of the other along the notch grooves 29 thereof. In this way, the container 25A containing the eight groups of cartridges is transported to the reader printer, and is loaded into the main body 26 of the cartridge loading device A. Under such conditions, the following search operation will be performed.

First, it is determined whether or not a cartridge has been set based on a signal from the detection means 41 shown in FIG.

The signal from the detection means 41 is sent to the CPU 74 via the CPU 74.
71 (Sl). If the container 25A in which the cartridge is set is not attached to the main body section 26, "Not set" will be displayed on the display section 24B of the controller 24.
is displayed, and if it is installed, "Set" is displayed (S2, S3). Next, when the execution key is pressed, a signal indicating that the execution key has been pressed is sent from the CPU 71 to the CPU 74, and the CPU 74 instructs the drive circuit 73 to load the cartridge, and drives the cartridge loading mechanism, as shown in FIG. The first cartridge is loaded into the cartridge loading section 20 as described in FIGS. (1) to (4) (S4 and S5). The code reading sensor 39A reads the identification information of the cartridge loaded in the cartridge loading section 20, which is encoded by a label such as a bar code, etc. on a label, and the read information is transmitted to the CPU 74 and the CPU 71. The data will be stored in the storage unit 72 via. Then, the read cartridge number is displayed on the display section 24B of the controller 24. For example, if the number of the loaded cartridge is number 20, it will be displayed as r20-J. By displaying the loaded cartridge number in this way, search information can be input efficiently (86.87). Next, when the execution key is pressed without pressing the cancel/stop key, a microfilm transport signal is sent from the CPU 71 to the CPU 74, the CPU 74 instructs the drive circuit 73 to drive the film transport mechanism, and the microfilm transport signal is sent to the CPU 74. is loaded by the film transport mechanism 3 (88-510). On the other hand, if the Cancel/Stop key is pressed before the Execute key is pressed, the Cancel/Stop key is pressed.
The fact that the stop key was pressed is stored in the storage unit 72, and 323
The processing of subsequent steps will be executed (S 1
1). When searching for a cartridge with rope ink, the operator looks at the cartridge number displayed on the display section 24B and the target frame number written on the instruction sheet, and operates the controller 24 shown in FIGS. 1 to 3. The address in which the image to be searched is imprinted, in other words, the search information is input from the key part 24A. This address is entered by manually entering the target frame number using the numeric keypad. For example, 10 of that cartridge
When searching for the 00th, 1500th, and 1600th frames, press 1000 using the numeric keypad and then press the memory key. Similarly, r1500. Memory key” r1600. Memory key”.

This address input work is done because the loaded cartridge number is displayed on the display section 24B.
Since the display section 24B is provided near the operation key section 24A, operations can be performed very efficiently while viewing the instructions (S12). In this way, when the input of search information based on the instructions is completed and the set key is pressed,
The search information entered so far or the CPU shown in Figure 14
71 to the storage unit 72 (813, 514
). The CPU 74 inputs the search information stored in the storage section 72 via the CPU 71, and performs search processing for the target frame based on the search information. Since this search process is a well-known process that is normally performed, a detailed explanation thereof will be omitted (S15). As a result of this search process, if a target address, that is, a target frame is found, the address of the target frame is displayed on the display section 24B, and the image of the frame is projected onto the screen 10. Further, if it is not shown in the flowchart or there is a need to copy the image, the copying process will be performed by pressing the print key. Regarding the copying process, the necessity of copying may be input in advance when inputting the search information, so that the copying process is automatically executed. Further, the number of the search frame displayed on the display section 24B is, for example, 150 where the target frame is cartridge number 20.
If it is the 0th one, r20-1500J is displayed (816.317). If the target frame is not found, the search information is stored in the storage section 72, and at the same time, "No address" is displayed on the display section 24B of the controller 24. As a result, the operator can easily know if there is an input error in the search information, and can move on to the next search (818, 519). When the search for one frame is completed and the user wants to search for the next target frame, the user only needs to press the enter key (S20). However, as mentioned above,
If the copying process is automatically executed and there is no need for the operator to check the image of the target frame, the operator may wait for the completion of the copying process and then directly search for the next target frame. If the enter key is pressed and another search address has been entered manually for that cartridge, the above processes from 815 to 820 are repeated. Incidentally, when adding the search address of the target frame, the address can be additionally input in this step (C821).

When all the frames for that cartridge have been searched, a rewind signal is output from the CPU 71 to the CPU 74, and the film transport mechanism 3 is activated to rewind the microfilm one time (S22). If there is, it operates as shown in Figures (5) to (8) in Figure 15, and the loaded cartridge is ejected and the next cartridge is loaded at the same time, and the S
Steps 5 to 822 are repeated for all cartridges stored in the container 25A. Note that whether or not there is an unloaded cartridge is determined based on the detection signal of the cartridge detection sensor 39B (823).
). Furthermore, when rewinding is being performed, "Rewind" is displayed on the display section 24B (S
22). When the search for the loaded cartridge is completed, the cartridge is ejected, and the display section 24B displays "Search Complete" (S
24). Finally, the contents of the information stored in steps Sll and S18 are displayed on the display section 24B. For example, if there is a cartridge whose search was canceled, that cartridge number or "28 Kensakunan" will be displayed, and if the 4500th frame of the 20th cartridge cannot be found, that information or "20- 450
0 Nan” is displayed. If there are multiple items that have not been searched as described above, the display can be switched by pressing the enter key (S25). When the execution key is pressed, all search processing ends, and "End" is displayed on the display section 24B (S26). Then, the state returns to a state where the next search operation can be performed.

In this way, a series of search processes will be performed.

In the above embodiment, cartridge B is identified based on the identification information affixed to it, but it is also possible to identify the cartridge B based on the identification information imprinted on microfilm. However, it is possible to perform a series of search processes. If the identification information is imprinted on the microfilm in this way, the identification information may be read by the sensor 23 that detects the blip mark. still,
In this case, the code reading sensor 39A is not required. Therefore, in order to automatically search for items of this type, it is first necessary to load the microfilm and read the identification information.
The film loading process in the SIO step of the flowchart shown in the figure may be performed after the cartridge loading process in step 85.

Further, when the cancel/stop key is pressed in step 88 of the flowchart shown in FIG. 16, S22 All you have to do is go back to the steps above. In this embodiment, the sensor 23 functions as identification information reading means.

When the search for all cartridges is completed in this way, the searched cartridges are stored in the container 25B. The container 25B containing the eight groups of cartridges is then removed from the main body 26 and transported to the storage shelf, and each of the stored cartridges B is returned to the original storage shelf. The cartridge B is then stored in the container 25B again based on the instructions and used repeatedly for searching.

As described above, the cartridge is automatically loaded into the cartridge loading section 20 from the container containing the cartridge, and the number of the loaded cartridge is displayed immediately after loading, so the operator can There is no need to input search information while looking into the loading section and looking at the back label of the loaded cartridge, and it becomes possible to input search information accurately and efficiently while looking at the controller. Furthermore, after the search for one cartridge is completed, the cartridges are loaded and ejected almost simultaneously, which improves search efficiency and work efficiency. In addition, since the cartridge is identified by a label attached to its top surface,
This can easily be done with conventional cartridges.

In the above embodiments, the display section 24A functioning as a display means displays identification information and search information, but it may also display each separately. good. Further, although the description has been given by way of example of a type in which cartridges are automatically loaded, the present invention is also applicable to a type in which cartridges are manually loaded one by one.

In addition, as an information format for identifying cartridges,
Although a barcode-shaped barcode pasted on the top surface of the cartridge is shown as an example, the present invention is not limited to this, and the barcode may be of a type in which identification information is recorded magnetically, for example. In addition, although we have given an example of identification information that records the cartridge number, other identification information that can identify the cartridge may also be used, such as the date, company name, etc. It may be something. Furthermore, in the above embodiment, the identification information of the cartridge is read only when the cartridge is loaded into the loading section, but when a container containing a plurality of cartridges is loaded into the cartridge loading device, The identification information of the cartridge stored in the container may be read in advance. In short, it is only necessary that the identification information of the cartridge be read before the cartridge is loaded into the loading section.

Further, in the above embodiment, an automatic search in a cartridge containing a roll of microfilm has been described, but the present invention can also be applied to an automatic search using a container containing a stack of fish films. Furthermore, although in the above embodiment, two containers are attached to the cartridge loading device, it is also possible to attach only one container. Specifically, one container is movably attached, and while moving this container, the cartridges to be loaded are positioned in the loading section, and the positioned cartridges are loaded one by one, and the used cartridges are loaded. It may also be in the form of being returned to its original location in the container.

Furthermore, although the above embodiments have been exemplified using a cartridge loading device that automatically loads a plurality of cartridges one by one, the present invention is not limited to the use of such a cartridge loading device; The present invention can also be applied to an apparatus in which cartridges are manually loaded individually.

Effects of the Invention As is clear from the above explanation, according to the present invention, the content of the loaded cartridge identification information is displayed on the display means provided near the search information input means. Therefore, input of search information becomes easy and search efficiency can be improved.
