Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a page mark attached to each image frame recorded on a long microfilm and a plurality of image frames attached as necessary. The present invention relates to a microfilm retrieval device that searches for a designated image frame by detecting file marks or block marks to be classified, and positions the designated image frame at a predetermined position.

[Prior art]

Generally, on a long microfilm that is wound on a reel in layers, narrow marks called blip marks are attached near the image frames corresponding to the image frames recorded on the microfilm. . Hereinafter, such a mark for each image frame will be referred to as a page mark.

Furthermore, there are cases in which a plurality of image frames with related contents are continuously recorded (for example, the entire text of a patent specification). In order to classify such related image frames, blip marks, which are slightly wider than page marks, are sometimes attached. Hereinafter, such a related mark for each image frame will be referred to as a file mark. Furthermore, there are cases in which files with related contents mentioned above are classified by field, etc. (for example, patent specifications and related technical documents, or chapters 1 and 2 of one book, etc.). In order to classify a plurality of related files, in addition to page marks and file marks, blip marks, which are wider than file marks, may be added. Hereinafter, such marks for each of multiple files will be referred to as block marks.

Flip marks (page marks, file marks, block marks) are attached to both ends of the microfilm in the width direction, and mark detection sensors are installed corresponding to the positions of both ends. Flip marks are now detected.

Here, if three types of blip marks are attached,
The operator can specify block marks, file marks, and page marks by inputting three types of numbers from the keyboard. For example, 3. 2. 1
If 0 is input, the 10th page of the 2nd file of the 3rd block is specified.

When each mark is designated, the microfilm is conveyed in its longitudinal direction, and first the block mark of the third count is detected. From this point on, the second count file mark is detected, and after that detection, the tenth count page mark is detected. Searching for image frames in this way is easier than searching by counting page marks sequentially from the beginning, and the search time can be shortened.

In the microfilm retrieval device, the retrieved image frames are positioned on the optical axis for projection onto a screen.
It is enlarged and projected. Furthermore, the projected image can be copied if necessary.

By the way, page marks attached to microfilm,
The width dimensions and positions of file marks and block marks may vary depending on the state of recording on the microfilm. For this reason, there are problems in that the same microfilm retrieval device cannot identify the marks or cannot properly position the image frames. For example, the page mark may be on the image frame center line or on the extension line of the frame edge.

In such cases, the size, position, etc. of marks are not standardized and there are various types, so in the past, several modes were used in which the parameters of the frequently used mark width dimensions and information on the marking position were set in advance. I try to remember it. This allows the operator to reliably perform image frame retrieval work by selecting a mode that is compatible with the microfilm being used.

[Problem to be solved by the invention]

However, there are over 20,000 types of parameter selections, and only a few of them are stored, so
When using a microfilm with blip marks in a completely different position and size from the microfilm originally used, a problem may arise in that the stored mode cannot be used. In such a case, it has conventionally been necessary to change the design of the internal circuit, which has been inconvenient.

In consideration of the above facts, the present invention provides a microfilm retrieval device that can freely rewrite the mode in accordance with the microfilm used, store the rewritten mode, and set the mode with a simple operation. The purpose is to obtain.

[Means to solve the problem]

The invention described in claim (1) provides a page mark attached to each image frame recorded on a long microfilm and a file mark attached as necessary for classifying a plurality of image frames. Or a microfilm retrieval device that searches for a specified image frame by detecting a block mark and positions the specified image frame at a predetermined position, which includes data on the position and size of the page mark and the file mark or block. a specific mode setting means for setting a specific mode that is compatible with the microfilm based on the input data, in which data regarding the presence or absence of a mark, position, and size can be input; and a specific mode set by the specific mode setting device. and a selection means for selecting a predetermined specific mode from the plurality of specific modes stored in the mode storage device.

In the invention according to claim (2), the specific mode setting means includes a display section that displays contents to be input, and an input section that inputs a setting value according to the displayed contents. It is characterized by

[Effect]

In the invention set forth in claim (1), the specific mode setting means determines information such as the size of the page mark, its position relative to the image frame, etc., for example, whether it is attached above or below the image frame, and its relative position relative to the image frame. Enter the location, the width range, etc., and set the specific mode. This specific mode is stored in the storage means. In memory means,
A plurality of types of specific modes set by the specific mode setting means can be stored, and the operator selects a predetermined specific mode by the selection means depending on the microfilm to be used.

In this way, information such as page marks can be rewritten, so even if you use a microfilm that does not correspond to the stored specific mode, you can easily set and store a specific mode that is compatible with this microfilm. It can be fixed and operability improved.

In the invention described in claim (2), a display section is provided as a specific mode setting means, and a plurality of pieces of information can be set in a so-called interactive format in which the contents of a plurality of pieces of information are sequentially displayed and inputted using an input section. , the operation at the time of rewriting becomes easier.

〔Example〕

FIG. 1 shows a reader printer 10 according to this embodiment. In this reader printer 10, a screen 16 for projecting an image recorded on a microfilm 14 is arranged on the front surface of the casing 12 (right side in FIG. 1). A cartridge 18 containing a layered layer of microfilm 14 is loaded into a loading section 20 provided slightly below the screen 16, and the tip of the microfilm 14 inside the cartridge 18 is placed inside the device. is wound onto a take-up reel 22. A light source 24 is installed between the cartridge 18 and the take-up reel 22 in correspondence with the microfilm 14. The light beam emitted from the light source 24 passes through image frames arranged along the optical axis, and is guided toward the screen 16 via an optical system composed of a lens 26 and a plurality of reflective mirrors 28. ing. As a result, microfilm 1
4 can be enlarged and projected.

Note that by changing the direction of reflection by the optical system (for example, by making the mirror 30 retractable along the optical axis as shown by the imaginary line in FIG. 1), the transmitted image can be transferred to a copying device installed below the device. 32. The copying device 32 can enlarge and copy the image recorded on the microfilm 14.

FIGS. 2A and 2B show details of the loading section 20. The cartridge 18 has its supply reel 34
A supply motor 400 (hereinafter simply referred to as reel 34 ) is connected to a rotation shaft 42 of a supply motor 400 connected to a control device 38 via a torque control section 36 . In addition, the supply motor 40
is rotated with a constant weak torque in the direction in which the microfilm 14 is wound onto the reel 34 (in the six directions of arrows in FIGS. 2(A) and 2(B)). The leading end of the microfilm 14 wound up in a layer on the reel 34 is pulled out from the opening 44 provided in the car + J edge 18 by the driving force of a loading roller of a loading mechanism (not shown), and is pulled out to the guide rollers 46, 48. After being wound, it is wound onto a take-up reel 22. Film detection sensors 49 and 51 for detecting the presence or absence of the microfilm 14 are located near each of the guide rollers 46 and 48.
is located.

The outer periphery of an endless conveyor belt 52 is in contact with the shaft 50 of the take-up reel 22 . This conveyor belt 52 has elasticity and is wound around guide rollers 54, 56, 58. Further, this conveyor belt 52 is connected to a drive reel 66 attached to a rotating shaft 64 of a take-up motor 62 which is connected to a control device 38 via a speed controller 60.
is wrapped around. Therefore, the conveyor belt 52 is moved in the direction of arrow B in FIGS. 2A and 2B and in the opposite direction in response to the rotation of the drive reel 66.

The microfilm 14 is transported between the conveyor belt 52 and the shaft 50.
It is held between the conveyor belt 52 and is wound onto the shaft 50 or pulled out from the shaft 50 in accordance with the movement of the conveyor belt 52.

A driven roller 68 is in contact with the conveyor belt 52 .

This driven roller 68 is attached to a rotating shaft 72 of an encoder 70, so that the drive state of the conveyor belt 52 can be detected by the encoder 70 as a Lux number. Encoder 70 is connected to control device 38 .

A slit plate 74 is provided between the guide roller 46 and the guide roller 48, slightly closer to the guide roller 46 than the optical axis. channel)
A pair of light receiving elements 76 are attached correspondingly.

Corresponding to the light receiving element 76, an LED 78 is attached to the opposite side of the microfilm 14, and the light receiving element 76 receives the light emitted from the LED 78 and transmitted through the microfilm 14. The light receiving element 76 and the LED 78 are each connected to the control device 38.

As shown in FIG. 3(A), blip marks 80 are attached to both ends of the microfilm 14, and the presence or absence of the blip marks 80 can be detected by changes in the amount of light received by the light receiving element 76. It looks like this.

The distance M between the light receiving element 76 and the optical axis is constant (75 mm in this embodiment).
After detecting the image frame 14A specified in step 6, it can be positioned to a position along the optical axis by moving it by a dimension M.

The blip mark 80 includes a page mark 80P1 and, if necessary, a file mark 80F1 and a block mark 80B, as shown in the section of the prior art, to classify a plurality of image frames 14A.

The control device 38 includes a CPU 82, a RAM 84, and a ROM 86.
, an input/output port 88, and a bus 90 such as a data bus or a control bus that connects these.

A keyboard 92 and a display 94 are connected to the input/output port 88 as specific mode setting means.

The keyboard 92 is normally used to specify the image frame to be projected onto the screen 16, and the block number,
By inputting the file number and page number required for the microfilm 14 being used, each mark is detected by the light receiving element 76 while the microfilm 14 is being transported, and the designated image frame is searched. It looks like this.

That is, the microfilm 14 has a page mark 8.
Some have only 0P attached, while others have two types of page marks 80F and file marks 80F, or three types including block marks 80B. Furthermore, the size and position of the blip mark 80 differ depending on the microfilm 14 used. For example, as shown in FIG.
In A), a file mark 80F1 and a block mark 80B are attached to the A channel side, and a page mark 80P is attached to the B channel side. Further, these marks are equally distributed from the center line P of the image frame 14A.

In addition, as another example, in the microfilm 14 shown in FIG. 3(B), the size of each mark (lengthwise dimension of the microfilm 14) is the same as that in FIG. 3(A), but the position thereof is , one end of the mark is aligned with the extension line of the left edge of the image frame 14A.

Therefore, the RAM 84 of the control device 38 has multiple types (
In this embodiment, nine types of modes can be stored in advance. The keyboard 92 is provided with a mode key 96 and a search/setting key 98 in addition to a numeric keypad and alphabet keys (not shown), and by operating the mode key 96, a parameter setting mode is read from the ROM 86. ing. In this parameter setting mode, the information parameters required for one mode (see Figure 4) are displayed one by one on the display 9.
4, and by operating a search/setting key 98 on the keyboard 92 after inputting a setting value, the next parameter is displayed in a so-called interactive format. Each set mode is set in mode register 1.
9 are classified and stored in the RAM 84. Furthermore, the contents of the mode set previously can be freely rewritten. Furthermore, what is the content of each display in Figure 4? The number after the mark is the number currently stored.

The operation of this embodiment will be explained below with reference to the flowchart of FIG.

First, the microfilm 14 to be used is inspected, and it is determined whether there is a suitable mode among the pre-stored modes. If a suitable mode exists, the mode register number (1-9) is input from the keyboard 92 (step 200). This results in step 20
2, a parameter corresponding to the input mode register number is read out from the RAM 84, and control is thereafter performed in accordance with this parameter. Note that if a suitable mode does not exist, no input is made in step 200, and the process moves to step 204, where it is determined whether or not the mode key 96 has been operated.If the determination is negative, steps 200 and 204 are repeated. . When the mode key 96 is operated in step 204, it is determined that rewriting is necessary, and the process moves to step 206. This rewriting procedure will be described later.

After a particular mode is set, first
Load 8. When it is determined in step 208 that the microfilm 14 has been loaded (for example, it is determined by the on/off state of a microswitch, etc.), the process moves to step 210, where the loading mechanism operates and the outer circumferential loading roller of the microfilm 14 comes into contact with the microfilm 14. , pull out the tip. The pulled-out microfilm 14 reaches the take-up reel 22 via the guide rollers 46, 48, and is held between the conveyor belt 52 and the shaft 50. As a result, the moving force of the conveyor belt 52 is transmitted to the microfilm 14, and the shaft 5
Winds up to 0. When a predetermined amount of the microfilm 14 has been wound onto the shaft 50, the movement of the shell conveying belt 52 is stopped and the microfilm 14 is in a standby state.

Here, in step 212, an image frame is specified using the keyboard 92. For example, if you input 3.2.10, the control device 38 recognizes that it is the ID page of the image frame recorded in the 2nd file of the 3rd block.
The process moves to step 214 and positioning control is performed. As shown in FIG. 6, this positioning control first drives the take-up motor 62 (for example, forward rotation). When the take-up motor 62 rotates, the conveyor belt 52 is moved, and the microfilm 14 is taken up onto the shaft 50 at the same time.

In the light receiving element 76, when the microfilm 14 is transported, the L
Each blip mark 80 passing between the ED 78 and the light receiving element 76 is counted. That is, in this case, when the block mark 80B is counted 3, the file mark 80F is counted 2, and the page mark 80P is counted 10, the drive of the take-up motor 62 is stopped and the number of pulses by the encoder 70 at this time is reset ( 0)
do. The microfilm 14 is a take-up motor 62
The drive of the take-up motor 62 is not stopped immediately after the drive of the microfilm 14 is stopped, but is stopped after a slight overrun. to stop. In this case as well, there is a slight overrun and the number of pulses becomes negative, so the designated frame is rotated forward at a lower speed and stopped at a predetermined position (a position taking dimension M into consideration). Thereby, the positioning of the designated frame on the optical axis is completed, and the image transmitted by the light source 24 can be projected onto the screen 16.

In the next step 216, the loaded cartridge 18
It is determined whether or not the search has been completed. If the determination is negative, the process moves to step 212, and if no image frame is specified in step 212, steps 212 and 216 are repeated. If it is determined in step 216 that the process has ended, the process moves to step 218, where all the microfilms 14 are wound onto the cartridge 18, and the process ends.

Here, when applying another microfilm 14, the distance dimension between the light receiving element 7 and the optical axis is constant, and if the blip mark application position is different, the microfilm after detection by the light receiving Yonago 76 will be The amount of movement will be different (third
(See Figures (A) and (B)). Also, if the sizes of each mark overlap (such as when the size of the block mark of the - microfilm and the size of the file mark of other microfilms are the same size),
It is not possible to determine which mark it is.

Therefore, in this embodiment, if the microfilm used is not compatible with the stored mode, the parameters in the mode can be rewritten. This rewriting procedure will be explained below.

First, as described above, in step 204, the mode key 96 on the keyboard 92 is operated. This results in step 20
6, mode parameter rewriting control is performed.

That is, as shown in Figure 4, the display 9
4, "Mode No.? 1" is initially displayed. Note that the numerical value at the end of the displayed content is the current setting value. Here, using the keyboard 92, input which mode register from 1 to 9 is to be rewritten. When the search/setting key 98 is operated when the input is completed, the next parameter "Type? 1" is displayed (the fourth
(■) in the figure, the operator can rewrite it with a predetermined value.

In this way, by operating the search/setting key 98 after inputting one parameter, the contents of the parameters are sequentially displayed. The parameters are displayed in the order shown in FIGS. 4 - 4, and their contents will be explained below.

■Setting register number ■Mark address type (presence/absence of each mark) ■Mark polarity (negative/positive) ■Setting numerical unit (inch/mm) ■Channel specification with block mark 80B ■Lower limit value setting for block mark 80B■ Setting the upper limit of block mark 80B ■ Specifying the channel with file mark 80F ■ Setting the lower limit of file mark 80F ■ Setting the upper limit of file mark 80F ■ Specifying the channel with page mark 80P ■ Setting the lower limit of page mark 80P Ω Page mark 80P upper limit setting ■ Specify simple (1 track)/duo (2 tracks) ■ Stop reference position (Y: mark left, N: center) ■ Maximum mark interval (corresponds to maximum frame pitch) ■ Stop position offset (dimension M (offset value based on (75 mm)) ■Counting mode by encoder 70 (image frames with file marks) ■Counting mode by encoder 70 (image frames with file and page marks) ■Counting mode by encoder 70 (with block marks) (Image frames) ■Count mode by encoder 70 (Image frames with block and page marks) ■Count mode by encoder 70 (Image frames with block and file marks) ■End of setting mode, after continuing, and after setting each parameter , the display of ■ in Figure 4 (”
QUIT(Y/N)? By inputting Y in ``, the process moves to step 220, where it is stored in the mode register number specified in ``■,'' and the process moves to step 200.Therefore, when using the mode register number, all that is needed is to input the mode address number. It can be controlled in a mode compatible with microfilm.

In this way, in the reader printer 10 of this embodiment, the operator can freely set or rewrite the mode that is compatible with the microfilm to be used by a simple operation, so that the operability is improved and the usability is improved. The scope of microfilm will also be expanded.

In this embodiment, the parameters are as shown in FIG. 4, but this is just an example, and the parameters are not limited to these.

〔Effect of the invention〕

As explained above, the microfilm retrieval device according to the present invention can freely rewrite the mode in accordance with the microfilm used, and can store the rewritten mode and set the mode with a simple operation. It has the excellent effect of being able to
