Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides information retrieval in an information retrieval device such as a reader printer that can perform frame retrieval for retrieving each information frame of a microfilm and item retrieval for retrieving a group of information frames such as a winter crop. Regarding control method.

For example, negative or positive microfilms as shown in FIGS. 1(a) and 1(b) are used in such information retrieval devices.

This microfilm 1 is connected to a starting end leader tape 1a that is latched to a take-up reel (not shown) and a terminal end leader tape 1b that is latched to a reel inside the cartridge.
Attach a black start mark MS (which becomes a set mark when returning) and an end mark ME to the connection parts, respectively.

Then, information is photographed and recorded at regular intervals on the film 1 between the two marks, and a large number of next information frames K are placed, a frame mark MK is attached corresponding to each information frame, and information for one item is added. A matter mark Mc is attached corresponding to the first frame of the information frame group KG (generally consisting of a plurality of frames, but sometimes a long frame containing information for one item) in which information is recorded.

Then, the information retrieval device detects the frame mark MK and subject mark Mc of this microfilm 1, and performs a frame search (search for each frame) and recessive search (search for each group of information frames for one item).
It is now possible to do this.

In other words, a key for forwarding one frame, a key for returning one frame, a key for forwarding one item, a key for reversing one item, a numeric keypad, a search key, a changeover switch for piece search and item search, a counter and a display that displays the count value, etc. In preparation, in the piece search mode, the counter counts the piece marks MK and displays the piece number on the display,
In the case search mode, the counter counts the case marks Mc and displays the case number on the display.

In either mode, you can advance and return one frame, forward and return one item, and you can automatically search by setting the piece number in the piece search mode and the item number in the item search mode with the numeric keypad in advance. It is now possible to do so.

By the way, for example, on microfilms that record patent publications, information for one item is generally recorded in a group of information frames with the number of frames corresponding to the number of pages of one item, with each page as one frame, but the first information In front of a group of pieces, there is often an information piece that records an index, list, etc.

In this case, after searching for the first piece with a subject mark in the group of information frames for the first item, there may be a case where it is desired to return to the first information frame without a subject mark.

However, in this type of conventional information retrieval device, when the first item marked piece is retrieved in the item search mode, the counter value becomes "1", so even if you press the key to go back one item later, it will not work. It is judged to be an incorrect operation and does not work.

In addition, in frame search mode, after the first frame with a subject mark is searched, operating the l-frame back key will move the film back one frame, but operating the one frame back key will send the film in the backward direction, but Since there is no attached piece, the player returns until the start mark Ms (in this case, becomes the reset mark) is detected and then stops.

Therefore, you cannot see the piece information (index, etc.) for pieces before 4 on the first piece with a matter mark, and if you want to see it, press the 1-frame back operation key the number of times equivalent to the number of pieces in front. I had to.

Therefore, the operation was very troublesome.

This invention was made in order to solve the above-mentioned problem, and in the above-mentioned information retrieval device, the operation key for returning one item after the first item mark piece (K-ri) is searched is not operated. This is intended to improve the operability when viewing indexes, lists, etc., by controlling the microfilm to return to the first information frame (Kl) and stop when the microfilm is pressed.

Therefore, the search control circuit of the information retrieval device according to the present invention drives the microfilm in the direction of returning when the key to return one item is turned on, and checks the item search switch and if it is OFF (frame search mode). , check the contents of the counter, and when the contents of the counter reach rlJ (when the piece mark of the first piece is detected, the rough film is stopped).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Now, if the print switch 8 shown in FIG. Move to the position indicated by the imaginary line. After the movement, the mirror clutch 41 is turned off. During this time, the rolled photosensitive paper 40 is started, cut into a certain length by a cutter 46, charged by a charging section 44, and reaches an exposure surface 46 by a vacuum belt 45.

Furthermore, when the print switch 8 is pressed, the lamp 34 that was irradiating the microfilm 1 at this point is turned off. When the photosensitive paper 40 reaches the exposure surface 46, it is temporarily stopped, and the cover 34 is turned on again to perform static exposure.

When the exposure for a certain period of time is completed, the lamp 64 is turned off, and the photosensitive paper 40 moves again toward the developing section 47. The photosensitive paper 4o that has entered the developing section 47 is developed with a developer, dried in a drying section 48, and then conveyed to the copy receiver 5. Further, when the exposure is completed, the mirror clutch 41 is turned on.
The second mirror 68 returns to its original position.

Note that 49 is a reflecting plate that reflects the light emitted by the lamp 34 toward the condenser lens 35.

Next, the film drive unit will be explained with reference to FIG.

A microfilm 1 is stored in a roll 51 within a cassette 50. Set the cassette 50 and press the search key 16. +1 piece key 14° +1 item key 22. By operating the feed direction of the manual dial 24, the solenoid 52 is turned on, the thread roller 56 moves toward the film surface, and at the same time, the drive motor 54 rotates.

The drive motor 54 rotates at low and medium speeds.

There are three speed levels. A detailed explanation of this speed will be given later.

In the above case, the film is fed at medium speed. Film 1 ejected from inside the cartridge set 50 by the thread roller 56
is inserted between the drive roller 55 and the press row 256.

When the film 1 is wedged between both rollers 55 and 56, a cab stance inch (hereinafter referred to as "CAP switch") 57 is turned on. When the CAP switch 570 is turned on, the solenoid 52 is turned off, and the film feeding force is applied from the drive roller 55.

Film 1 passes through film gate 58 and is wound onto reel 59. 60 is a film holding arm.

Then, when the jig start mark is read by the mark detector described later, the speed changes from medium to high speed (when the search key is "20" or higher) or low speed (+1 frame key).

+1 item key, when the search key is "19" or less). Thereafter, when the mark detector detects a predetermined mark, the advance of the film 1 is stopped, and the lamp 64 is turned on to project the stopped frame.

The mark detection section is constructed as shown in FIG.

Then, the microfilm 1 is illuminated by the light of the lamp 64.
The piece mark MK and the piece mark Mc are mirror 61.62
It is reflected by a lens 63, 64, magnified (doubled) by a mirror 65, 66, and reaches a piece mark detector 67 and a piece mark detector 68. The information on that piece is
The image passes through a projection lens 66 and is projected onto the screen 2 in FIG.

As shown in FIG. 7, the piece mark detector 67 has a sensor At
, A2. Bt, B2, and mark detector 68
is equipped with sensors A3 and Ba. Each sensor is
Specifically, it is a photodiode.

Sensors At and B1 of the piece mark detector 67 generate signals for counting piece marks, and sensors A 2 and B 2
A start mark signal, an end mark signal, and a reset mark signal (when the microfilm is fed in the return direction) are generated by At and Bl. Marri detector 68
The sensors A3 and B3 produce the mark signal.

Note that the microfilm 1 shown in FIG. 1 is used.

FIG. 8 shows a film drive circuit and its input and output signals, and the drive and feed direction of the drive motor 54 (Ml) shown in FIG. is,
The on/off of the solenoid 52 and the CAP switch 57 is controlled and sent.

Table 1 shows the relationship between the 700 Å force signal of this film drive circuit and the film advancing direction and speed.

When the CAP switch 57 is turned off, the solenoid 52 is turned off.

FIG. 9 shows the print control circuit.

When the print switch 8 shown in FIG. 3 is turned on by this print control circuit 80, the motor 81 (M2) for transporting the photosensitive paper is started and the rolled photosensitive paper 40 is moved as explained in FIG. Start. At the same time, the mirror clutch 41 is turned on, and when the second mirror 38 falls down, the mirror clutch 41 is turned off. The photosensitive paper 40 is cut into a predetermined length by a cutter 46 and stopped at an exposure surface 46 on a vacuum belt 45. At this time, a paper stop signal PST (FIG. 9) is output and at the same time the lamp 64 is turned on for exposure.

When the exposure is completed, the lamp 64 is turned off, the photosensitive paper 40 is fed again, the mirror clutch 41 is turned on, and the second mirror 6 is turned off.
8 and ejects the copy to the copy receiver 5.

Note that the print control circuit 80 does not include a signal from the copy number dial 26.

Now, suppose that the copy switch 29 in FIG.
) is output. Further, the mirror clutch 41 is also turned on, and the second mirror 68 falls. And photosensitive paper 4
When 0 stops at the exposure surface 46, a paper stop signal PST is output, and the U/Pro 4 lights up to perform exposure.

When the exposure is completed, the lamp 64 is turned off, and the photosensitive paper 40 is developed and discharged to the copy receiver 5.

In addition, in this copy mode, after the print signal P is output and the second mirror 68 falls down, the first mirror 68, which will be described later,
Turn off the mirror clutch from the search control circuit in Figure 2.
When the signal is received, the mirror clutch 41 is turned off separately from the print control circuit 80. After the exposure is completed by the stop signal and the photosensitive paper comes out from the exposure surface 46, a signal to light the lamp 34 is input and the lamp 64 is turned on, and the search control C1 in FIG. 12, which will be described later, is input.
- One frame of 90 ilil microfilm is sent by the signal from the roll circuit.

After that, the reprint signal is sent to the print control circuit 8.
0, the photosensitive paper 40 starts again to perform exposure, and when the photosensitive paper 40 comes off the exposure surface, the frame is advanced by one frame, and at this time, the exposure mark M is displayed. When the second mirror 38 is detected, the mirror clutch OFF signal is turned off, the mirror clutch 41 is turned on, and the second mirror 38 returns to its original position, thereby completing the copying process.

FIG. 10 shows the operation timing of each part during normal copying, and FIG. 11 shows the operation timing of each part during special copying.

In both figures, TM is the time until the second mirror 68 falls, TEX is the exposure time, and TK is the Komagome time.

TI and T2 are timer setting times of a program timer in the horizontal 1 control circuit 90 in FIG. 12, which will be described later.

Also, in Fig. 11, tl is the start of the first sheet of photosensitive paper, t
2 indicates the discharge of the first sheet of photosensitive paper, t3 indicates the start of the second sheet of photosensitive paper, and t4 indicates the timing of detecting the subject mark.

FIG. 12 shows the search engine in this embodiment.

1 is a diagram showing the relationship between a loop circuit and its input/output signals; FIG.

This search control circuit 90 uses a one-chip microcomputer that includes a central processing unit (CPU), a ROM as a program memory, a RAM as a data memory, and the like.

In the input system, on/off signals from each operation key or switch of the operation panel 4 shown in FIG. 3 are input. Note that the manual dial 91 is a switch that is turned on when the manual dial 24 shown in FIG. 3 is rotated.

The ninth frame switch 92 is a switch inside the machine, and is a frame number selection switch that changes the film speed from high speed to low speed during retrieval. When the ninth switch 92 is off, the search control circuit 90 switches to low speed 19 frames before, and when it is on, it switches to low speed 9 frames before.

However, even if the ninth frame switch 92 is off, the signals from both switches are inputted via the OR gate 93 so that it is switched before 91Ii111 when the item search switch 28 is on.

Further, from the film drive circuit 70 shown in FIG. 8, a direction signal indicating the feeding direction of the microfilm and a CAP switch on/off signal indicating whether or not the microfilm is being loaded are input.

Furthermore, from the print control circuit 80 in FIG.
A paper stop signal PST, which is output when the photosensitive paper stops on the exposure surface, and a print signal P, which is output when the print switch is turned on, are input.

However, the print signal P is inputted via an AND gate 94 that performs AND with the output of the copy switch 29 so that it is input only when the copy switch 29 is on.

Also, the sensors Al, Bl, A2 . B2 and mark detector 68
sensor A3. The output signals of B3 are respectively input to the mark preprocessing circuit 95 to discriminate each mark, and produce a start mark signal, an end mark signal, a reset mark signal (when the microfilm is sent in the return direction), a frame mark signal, and A subject mark signal is output and input to the search control circuit 90.

The positive switch 96 is a switch that is turned on when the loaded microfilm is positive and turned off when it is negative.

As for the output system, MID (medium speed), GO (high speed), and REW (return) are output as each film drive related output to the film drive circuit 70 in FIG.

Outputs MSTP (motor stop during manual) signals.

Also, a mirror clutch OFF signal and a lamp ON signal are sent to the print control circuit 80 in FIG.

Outputs a reprint signal.

If the operator makes an erroneous operation, an erroneous operation signal 5Ml5S is output and the buzzer 97 sounds to warn the operator.

Also, in the piece search mode, the piece number is output, and in the case search mode, the case number data (contents of the display register in the RAM) is output, decoded by the decoder 98, and displayed on the 4-digit numerical display 27 by the 7-segment LED. indicate. In this case, each digit of the numeric display 27 is sequentially and dynamically displayed by the switching signal Sc.

Next, the operation of the search control circuit shown in FIG. 12 will be explained with reference to the operation flowcharts shown in FIGS. 14 to 65.

14 to 16 show the main routine.

When the power switch is turned on, the process starts from 5TART in FIG. First, the RAM output port is cleared. Next, set the counter and display register DGIT (
This is the address 38-3F of the RAM map in Figure 16.
Set the upper bit of ``1'' to ``1''), set and start the internal timer. This timer changes the output to the display 27 mainly at each time of this timer of the display register, and lights up the display 27.゛ For details, refer to the timer interface.) Lu f: y (TIMINT
See ROTJTIN).

Next, check the input of the operation keys. If there is no key-in, reset various percentages and return to RESTAT.
If any key is pressed, check 4, which is used in various modes, is performed. Initially, this % is all 0", so it passes to the rNJ side, and then checks whether the numeric keypad 20 is pressed. If it is pressed, the number routine (THIS ROUTINE) is executed.
Go to , enter the number, and return to RESTAiT.
If it has not been pressed, the search key 16 is checked (FIG. 15). If it is ON, reset FAST/F and go to the search routine. During that process, MO
Go to VE3, get caught on the check of 5EAR/F=17, and fly to ■. Then, when the search routine processing is completed, RESETI or RESET 2
(at this time, the direction of film movement is ADV (advance))
RESETl when , RESE when REW (dark)
I'm going to T2. Then, return to RESTAT.

In addition, when entering the search routine, if there is an erroneous operation condition described later, OPM IS S, which is an erroneous operation flow.
Go to , use the error operation routine to sound the buzzer 97 for a certain period of time, and return to RESTAT.

If the search key 16 is not ON, go to ◎ in FIG. 16, reset FAST/F, and check the +1 frame key 14. If it is ON, go to the +1 piece routine. Then, if there is an incorrect operation condition, go to OPMISS,
Otherwise, process. During that process, jump to MOVE3 in Figure 15 and press + I KOMA /,, =
1? I got caught in the check and returned to ■. When the processing is completed, the process returns from RESET 1 to RESTAT.

If the 11th frame key is not ON, check -1 frame key 15° + 1 item key 22 and -1 item key 26 (16th
figure). Then, when those keys are ON, -1 piece routine and +1 piece routine.

The -1 piece routine also processes in substantially the same way as the +1 piece routine described above.

If the 11 item key is not ON, check the rewind key 21 (FIG. 16). If it is ON, the program goes to the rewind routine, and during that process jumps to MOVEI in FIG. 15. In this case, the program does not return to the rewind routine after jumping to MOVEL. When you jump to the MOVE routine, is the stop key ON? Check or reset mark? If either is checked, the process jumps to RESET 1 and the process ends here. and RESTATE again
Return to

If the rewind key 21 is not ON, the preset key 19 is checked. If it is ON, the contents of the display register are transferred to the counter, the process ends, and RESTAT
Return to

If preset key 19 is not ON, clear key 18
Check. If it is ON, it resets the display register and returns to RESTAT.

If the clear key 18 is not ON, check the print signal. If there is a print signal, the process enters the copy routine and returns to RESTART when the process is completed. If there is no print signal, a manual routine is entered.

During the manual routine, it is determined whether the manual switch is ON or not. If it is ON, the manual routine is entered, and during processing, the process jumps to MOVE2 in Figure 15, and the MANU
/F=17 I got caught in the check and entered the manual routine again from ■. If it is not ON, R
Return to ESTAT.

At RESET 2 in FIG. 15, reset END /, , and go to RESET 1. RESET 1
The difference between RESET 2 and RESET 2 is whether or not to reset END/F, and processing in the feed direction (+1 frame, +1 item,
At the end of search feed direction), jump to RESET 1,
Processing in the backward direction (-1 piece, -1 item, search backward direction)
Jump to RESET 2 at the end of . This means that END/, which is set when the end mark is detected, is reset after processing in the return direction'.

The RESET 1 routine is MOVE 1 /, , ,

5EAR/F-0°REW'/, When =O, the contents of the counter are entered into the display register.

What this means is that when the search key is pressed and the rewind key is pressed, the numbers in the display register do not match the contents of the color/color, but remain as they are.

Then, check C0PY/F=1 and select YES1.
, jump to CRYlo, and if NO, return to RESTAT.

Next, the MOVE routine will be explained. HaM in MOVE3

A search routine, +1 piece routine, and ±1 item routine fly to E3.

Then, check C0PY /F=17 and get YE
If S, the stop key 17 is not checked.

This is because the stop key 17 is used to issue a signal to interrupt copying during copying, so the stop key is not checked during copying. The check here is just to stop the movement of the film.

When C0PY/F-〇, check stop key 17. If the stop key is ON, go to RESETl, otherwise 5EARF/F=1, RE
Check W buttock and -1, and if both are YES, do not enter the contents of the counter into the display register. This is because the value of the display register is not changed during search processing and rewind processing.

Then, check the reset mark, and if YES, clear the contents of the display register and counter, and

If any 14 is 51'', the process returns to the respective routine.

If there is an end mark and MANU/F=1, the process returns to the manual routine shown in FIG. 16 from ①.

Next, the operation of each routine shown in FIG. 17 and subsequent figures will be explained.

FIG. 17 shows an erroneous operation (OPMISS) routine, which is a routine that sounds the buzzer 97 (FIG. 12) for a certain period of time at each erroneous operation condition.

It comes up when there is an error in operation, and first sets OPMISF/F to 0'' and checks BZ'/, = 1. Initially, it is B.
Z F/,, -〇 Therefore, set and start the buzzer timer and turn on the buzzer. Then, the output data is output until the buzzer timer times out.

Turn off the buzzer when the buzzer timer times out L
, set BZ/F to 1" and return to RESTAT.

At this time, if you are still pressing the operation key, the error operation condition will occur again and you will be redirected to this routine. and,
Set OPMIS/ to 0 again and check BZF/F. At this time, BZ/F is 1, so do nothing and return to RESTAT.

Then, when you release the key that was being operated incorrectly, the key-in check NO is set to 1, as shown in the main routine.

Figure 18 shows the number setting (THISU) routine, which is as follows. This is a routine for inputting numerical data from the numeric keypad 20 into the display register.

TEN/,=1 is checked, and since the initial result is NO, next, FAST/F=1 is checked. Since the first number entered is No, FASTζ is set to 1, the display register is cleared, and the data from the numeric keypad is entered into the first digit of the display register. And R.E.S.T.A.T.A.T.

FIG. 20 shows a timerinterrupted (TIMINT) routine, which is an interrupt routine for the internal timer of the microcomputer.

First, the timer jumps to overflow TIMINT. The digit currently displayed on the display is 4.
It is checked whether it is the digit, and if No, the next digit to be displayed is moved (for example, if the second digit is currently being output, the third digit is to be output).
If the fourth digit is being displayed, set the first digit to be displayed next.

Then, count down the buzzer timer data (do nothing when the buzzer timer is 0).

Then, the internal timer is set and started again, and the process returns.

Since there is no interrupt-disabled routine, this timer interrupt can occur while any routine is being passed.

FIG. 21 shows the +1 frame (PSIKOM) routine, which is a routine that advances the microfilm frame by one frame.

When this routine is entered, +IKOMA/F is first checked. Initially, +IKOMA/F is “0”, so it comes to NO. Then, check END/P=1, and if YES, it is an error operation condition, so OPM
Fly to ISS routine. No big C check CCCHF, CK) Pass through routine.

This CCHECK routine, as shown in FIG. 28, is a routine that checks the contents of the counter. If the counter content is “0OOOJ, C=O/F4-1°”99
If 99J, C=9999F/F←1. [0OOIJ
Then, this is a routine that performs C=IF/F←1.

Returning to FIG. 21, check C=9999/F=1, and if YES, it is an erroneous operation condition and the process goes to the OPMISS routine (FIG. 17). The counter is “999.9J”
However, if you move +1 frame, it becomes "0000", so it is considered an erroneous operation.

If C=9999/,=l is NO, go to the 0PSTAT routine. This routine loads the film at medium speed if the film is not loaded, then slows it down at the start mark, and if the film is not loaded, the routine returns after checking for any erroneous operation conditions. .

The 0PSTAT routine will be explained in detail with reference to FIG.

First, the contents of the counter are checked through the CCHECK routine, and PMKC=0/F=1 is checked. This 4 is now set if the content of the counter after +1 piece or - piece operation is performed at the time of search. Therefore, here, if PMKC/F=1, the check for C=OImaichi1 is not performed. This is due to the proviso of 0 in the erroneous operation condition.

If PMKC/F=0, check C=0/),=1, and if YES, check whether the CAP switch is ON (check whether the film is loaded). If the CAP switch is ON in this state, check 5TART/F and
/F or O, set OPMIS/F. 5TA
If RT5 is X'1", it is normal operation, so set Go.
Go to the FMSTAT routine in Figure 60.

By the way, during normal operation, the operation key is ON, film loading, counter contents, CAP switch, 5TA
The relationship between RT/ and the operation timing of FILMF/F is shown in FIG.

In other words, when the content of the counter is "0000", CAP
If the switch is OFF or ON and 5TARTF+=1, it is a normal operation, but if the CAP switch is ON and 5TARTF-0, it is an incorrect operation.

Also, when the content of the counter is 10001 or more, CAP
If the switch is ON, it is a normal operation, but if the CAP switch is OFF, it is an erroneous operation.

Next, the FMSTAT routine will be explained with reference to FIG.

This is the routine that loads the film. In the above-mentioned 0PSTAT routine, when it is determined that the film is not loaded and the film is flown, the start mark is first checked. If No, check whether the CAP switch is ON. Initially N
o, so the MID signal is set to "1" and the film is run at medium speed.

Before this, the Go times signal has already been output in the 0PSTAT routine. (GO, -1, MID-1 becomes medium speed.

Then return.

Next, when returning to FMSTAT, the start mark is checked again, and if it is still NO, the CAP switch is checked to be ON. At this time, if the film is inserted into the drive blow 255 shown in Fig. 5, the CA
Since the P switch 57 is ON, go to YES.

Then, return to FM STAT again, check the start mark, and if YES, set the MID signal to 10", turn OFF /F and FILM.

Set.

In this way, the film is loaded at medium speed, and when the start mark arrives, the MID signal is set to XXO".

From this FMSTAT routine, the process returns to the OP5TAT routine. When film is being loaded, it returns through FILM/, -1.

Now, let's return to the PSIKOM route in Figure 21.

Upon return from the 0PSTAT routine, OPMI S'

is "1" if the film is loaded. To be precise, when the start mark is read, the FI
LM/F is set. Also, the contents of the counter are “
0000" and is set if the CAP switch is ON.

Therefore, when FILM/P=0, film force order -
Since it has not been marked, I simply set MOVEIF/P to ``1'' and return without reading the piece mark and subject mark.

-1, so first the contents of register R2 are output to the output port. Now, register R2 has GO-1゜DOWN4
Since it contains DATA to be set to -1, go here Go←1
．． DOWN←1, and the film will be fed at a low speed.

Then, check F1=1. Fl is a flag, which is used here to check the state of the mark at the start. Initially, F1=0, so go to NO and cenote Fl.

Then, check the piece mark, and if YES, mark it as MAR.
Set K/, set MOvEl/F, and return. If No, reset MARKF/F and
OvEIF/1. , and return.

What this does is check the initial state mark at which the film starts.

In the early days, the piece mark MK was sensor A like the 68th country.
If the center of the piece is at the center of s, A2, Bt, and B2, no piece mark output is output.

Therefore, the piece mark signal is in a rough state, but as shown in the same figure (B)
If there is a shift like this, the piece mark output is output and there is a piece mark. No matter which state you start from, you must send the pieces accurately.

Therefore, the count should not be increased by one in the state shown in FIG. 68(B). Therefore, the determination is made using the flag Fl.

When starting from the state of the 38th country, go through Fl-1 from the NO check of F1 = 1, go to NO by checking the piece mark, reset MARK/F and return, then go to PSRUTN again. When this happens, check YES for F1=1 and check the piece marks (separate from the above).

At this time, the film is still moving, but the next frame mark has not yet arrived, so I reset MARK/P and returned.

While repeating this path, the next piece mark comes, passes the check of the item search switch, and if NO, MARKF.
/F check goes to NO and goes to the counting routine.

Also, when starting from the state shown in Figure 68 (B), F1
From the NO check of =1, go through Fl-1, go to the YES check piece mark, and go to MARKF/I.

, then return to PSRUTH, check F1 = 1, go to YES, and check the piece mark.

If you have not yet escaped the first piece mark, Y
Go to ES and check whether the search switch is ON, and if No, check MARK/F.
At this time, MARK F/F- is 1 //, so MOVE1/p is set and the process returns without proceeding to counting.

Then, when the piece escapes from the first mark while spinning round and round, the piece mark check returns to NO, MARK/F is reset, and the process proceeds to a routine that counts the next time it comes around.

By doing this, the same counting can be performed no matter which state shown in Figure 68 (2) is started.

Then, the next piece mark comes and the piece mark check is YES.
When it comes to , check the search switch. If No, it is a piece search, so all you have to do is count the pieces. Therefore, next time, check MARK/F=1 and go to NO.
Count using POGNP1 routine.

Therefore, next, this POGNP1 routine will be explained with reference to FIG. 61.

This is a routine that adds 1 to the counter, but also includes a function that does not count at the first frame mark signal but starts counting from the second time onwards when using positive film.

In the case of positive film, the reason why we start counting from the second time is because of the difference in transmittance between the start mark MS and film 1, as you can see from the positive film in Figure 1 (b). Since the output is output as a mark signal, this first signal prevents the count from advancing.

(In the case of negative film, the count starts from the first time. Therefore, in the POGNPI routine, turn on the positive switch.
Check if it is, and if YES, C0UNT O
Check FF/F=1. This 4° is set after reading the start mark (30th
(in the FMSTAT routine shown in the figure).

If it is the first piece mark signal, C0UNT
Since OFF F/F = 1, we return to the PSRUTN routine in Fig. 36 without counting, set MARK/¥, and check again whether the positive switch is ON or not.
Go to YES and reset C0UNTOFF/Fe since C0UNT OFF F/F=1. From the second time onwards, it will be counted.

If the film is negative, it will go to No when checking the positive switch ON, so all counts will be made.

Then, from this POGNP t routine, P
Returning to the SRUTN routine, it sets MARK/ to mean that the counting process has finished, checks whether the positive switch is ON, and since it is No, resets 5TART/F and returns to the +1 frame routine in Figure 21. .
This completes the piece count.

Next, a case will be explained in which case marks are counted when the case search switch is ON in the PSRUTN routine of FIG. 66.

If the item search switch is ON, go to YES by checking the item search switch ON in Fig. 36.
Next, the issue mark is checked, and if there is no issue mark at this time, MARK/...-1 is checked.

When a piece has a piece mark and has no matter mark, it is a piece that does not have a matter mark Mc as shown in FIG.

Initially, MARK/F=O, so MARK',
/, = 1 check goes NO. And M.A.
Set RK/F and check whether the positive switch is ON. If it is a negative film instead of a positive film, go to No, reset the 5TARTF/F, and return. If it's a positive film, then it's C0TJNTOF

Reset NTOFF'4 and return. If NO, 5TART buttocks.

Reset and return.

Here, as mentioned above, since the frame mark signal is generated between the start mark and the positive film, in the case of positive film, the start mark t [CoUN
TOFF% is set, and it is determined whether the piece is marked for the first time or not.

Therefore, in this case C0UNT OFF F/F = 1
If so, it is the first piece mark, but without resetting 5TARTF/F, coUNTo
Return by resetting only FFF/F. C0LJNT
If 0FF-1=o, it is not the first piece mark, so 5TART/i is reset.

Next, we will explain what happens when there is an issue mark.

If you check YES in Figure 66, C-1
Reset /F and go to check if MARK/F=1, and if NO, go to POGNPl routine (Figure 31), count +1, set MARKF/F, and return through positive check.

In addition, in the case of positive film, as in the case of frame marks described above, the mark signal is generated at the start mark and the next frame of the film, so the first mark signal is not counted in the POGNP1 routine. ing.
When the subject search switch is turned on as described above, the count is not counted if only the piece mark MK in FIG. 1 is present, but only when the piece mark MK and subject mark Mc appear. (However, in the case of positive film, the first mark signal is not counted.) Now, when returning from the PSRUTN routine to the +1 frame routine in Figure 21, MOVE i l/F = 1

Jump to FF routine.

Therefore, the CZFF routine will be explained with reference to FIG.

This routine uses PMKC/
This is a routine that sets or resets PMK.
Details of the C/F function will be explained in the -1 KOMA routine. Here, in what cases should PMKC
Describe whether to set or reset +.

First, check whether it is a search. If it is not a search, you can return without doing anything. The process goes to the CCHECK routine shown in FIG. 28 only when the item search switch is ON. As mentioned above, this routine is a routine for checking the contents of the counter.

Here, the counter checks whether it is ``0000J.'' This is the C=OF/F=1 check.

If C=OFF-1, PMKCF'/F is set, and if NO, PMKCI/F is reset.
This is +1 piece ruch/after processing, if the counter is 0, P
MKCFF is set, and if it is not 0, PMKC/F is reset.

Returning to Figure 21, after passing through the CZFF routine,
Next, the program jumps to the ENDRN routine (Figure 64).

What this routine does is check the end mark. The end mark ME is attached to the end of the microfilm 1 as shown in FIG.

Therefore, even when this end mark is used, the piece mark and subject mark signals are output, so after processing the piece mark and subject mark, it is necessary to check whether the current mark is not the end mark ME. Routines are stuck after processing.

In addition to checking the end mark, it also resets the film drive circuit signal and checks whether frames that have stopped after processing are marked with an end mark.

This ENDRN routine will be explained with reference to FIG.

First, the film drive signals MSTP, DOW
N.

REW, reset GO. Since this is a +1 piece routine, DOWN and GO are V″1″.

This reset causes it to become "0" and the film stops.

Next, check whether there is an issue mark on the stopped piece, and if there is (YES) set KENMARKFIF, otherwise (NO) reset KENMARKFIF.

Next, check whether it is an end mark, and if it is ■, return without doing anything. If YES, END'/,
Set and return.

Returning to Figure 21 again, the +1 piece routine that returned from the ENDRN routine now jumps to RESETI,
Return to the main routine shown in FIG. 15.

C=9999ζtt reference reset, 5EAR'
/,=1REV'/,=1 is checked.

Since it is now a +1 piece, both go to the No side, put the contents of the counter in the display register, check C0PYF/F, and since it is NO, return to RESTAT in FIG. 14.

Then, if the ±1 frame key is not pressed, +IKOM
A/F is reset. This completes the processing of +1 piece.

Next, the +1 case (PS I KEN) routine shown in FIG. 22 will be explained.

This is a routine that moves the microfilm to the next marked frame. Note that the subroutines described in the +1 piece routine appear here as well, but their explanation will be omitted.

Jumping from the +1 key check in the main routine (Fig. 16), first the +IKENF/F-1 is checked. Naturally, at first it was "0", so I went to NO, and then I went to EN.
Check D'/, = 1. (Check END/F for the key that moves the film in the feed direction.) Next, check if Color/Re is "9999".
If No, go to the 0PSTAT routine (Figure 29). When you come out of there, check OPMIS/.

Up to this point, it is exactly the same as the +1 piece routine.

Then, set +IKEN/F and set G to register R2.
Input the data o-1, DOWN-1 and PSRUT
Go to the N routine and perform processing.

And when it comes out of the PSRUTN routine, the MOV
Check EI/P to see if it is in process,
If processing is in progress, the process jumps to MOVE3; if not, it is checked whether the processing has ended because of the issue mark or the piece mark.

If there is only a piece mark instead of a subject mark, the process must be continued again until the subject mark comes, so MO
Go to VE3, and when the issue mark appears, go through the ENDRN routine, stop the film, and go to RESET 1 to finish the process.

FIG. 26 shows the 11-frame (MSIKOM) routine, which is a routine that moves the microfilm frame back one frame.

When entering this routine, first -I KOMA /F-1
Check. At first it's No, then CA
Check the P switch ON and see if film is loaded. If NO, it is an erroneous operation condition and the process jumps to the OPMISS routine (Figure 17).

If YES, the program jumps to the CCHECK routine (FIG. 28) and checks the contents of the counter.

After that, check the subject search switch ON, and if NO, check C=1/p=1, and the contents of the counter are "
If 0OOIJ, OPMISS routine (Figure 17)
If not, check PMKC=O/F=1.

When the item search switch is ON, C=1/,=1 (D
No check is performed. This is because, as shown in FIG. 1, there is a case where the first frame with a subject mark has a frame before 4 (case number l).

In other words, when the item search switch is ON, 4 is placed on the piece with item number I.
Suppose that it is projected. At this time, the contents of the counter are “

If this is checked, the film will not be moved as it will result in an incorrect operation.

That would be a problem, so when searching for an item, the contents of the color/ri should be “1”.
” so that it is possible to move -1 piece, C=1'/.

-1 is not checked.

Next, we go to check PMKC = 0 '/, = 1, but PMKC = 0/F is the C in the +1 piece routine mentioned above.
It appeared in the ZFF routine (Figure 62).

In short, PMKC--4 is set to 5 if the counter contents are [0000J as a result of moving the film by ±1 frame or -1 frame. For example, in the film shown in Figure 1, when searching for an item, the frame with item number 1 has 4 to 11.
Use the piece key to project 3 on the previous piece. At this time, the counter changes to l-0000J.

Next, when projecting 2 onto the piece with piece number 2 using the -1 piece key,
If this PMKC=O body is not checked, C=- etc.
1 jumps to the OPMISS routine. However, if the check of C=O/P=1 is stopped, there is a problem that the above-mentioned erroneous operation conditions (■) and 0 will no longer be met. Therefore, PMKC=O/F is used to remove conditions such as the proviso for the erroneous operation condition @.

If the check of C=O/,=1 is NO, -IKOMA
/F is set and GO←1. is written in register R2. DOWN
4-1 Input the film drive signal data of REW-1 and jump to the MSRUTN routine (Fig. 65). This is similar to the PSRUTN routine (FIG. 33), and is a routine that simply increments the contents of the counter by 1.

Therefore, this MSRUTN routine will be explained with reference to FIG.

First, the data in register R2 is output to the output port.

Register R2 has GO←1. DOWN←l.

Because REW←l data is included, the film returns at low speed. Next, check Fl-1 and check the piece mark MK.

This is the same as the PSRUTN routine, so that even if the mark is misaligned, it will be counted properly. See the description of the PSRUTN routine for details.

Then, if there is a piece mark, go to check the item search switch. If NO, check MARKP/F,
At first it's No, so I subtract 1 from the counter and MARK/
Set F and return.

If YES in checking the item search switch, go to check the item mark. If the subject mark is NO, 5E
I checked ARF/F=1 and now I have No-c, so
Next, check MARK'/,=1.

Since the initial answer is NO, KENMARK F/F=1
Go check it out.

KENMARK /F is the ENDRN routine (64th
This is F now, which is set in the drawing, and it is checked whether or not there is a matter mark Mc on the piece after processing.

YES, KENMARK F/F-0, C-1
/F-IK. If no, don't do them,
Set MARK/F.

What this does is to SE C-1,i.
The decision whether to play T or not is determined by whether or not the previously stopped piece had an issue mark.

In other words, if the previously stopped piece has the issue mark Mc (for example, when it was stopped at the item number 51 in Figure 69), turning on the -1 piece key will move the next Pa piece. Now, when the counter is decremented by 1 and the 11th piece key is pressed again from the Pa piece, the counter is decremented by 1.

Returning to the flow shown in FIG. 65, if there is an issue mark, check +IC0FFF/F=1.

This counterfeit is set when +1 piece key operation is performed.
This is within the same information group (for example, Pt-Pa in Figure 69)
It is used to prevent a countdown when moving +1 piece or -1 piece. 11COFF; C for F-1
- MARKF without checking IF/F=1
Check /F=1 and return.

In short, here, when the 11 frame keys from case number 51 in FIG.

In any case from Pl to Pa, the content of the counter remains unchanged at 50, and when the piece numbered 50 is moved to the piece numbered 49, the content of the counter also becomes 49.

After going through such MSRUTN routine and returning to the 11th frame routine in Figure 26, MOVEIF/F
If the process is in progress, select MOVEI /F.
=1, so YES and jump to MOVE3. If it is after processing, go through the CZFF routine and END.
Go through the RN routine to check the reset mark.

This is because, as explained earlier, when searching for items, it is possible to move the pieces before item number 1, so if the first piece is stopped and you press the -l piece key, you can reset it. It is necessary to read the mark (same as the start mark), and it is checked here.

If NO, go to RESET2; if YES, go to C0RO. C0RO is a routine that resets counters and display registers.

Next, the eleven (MS I KEN) routine shown in FIG. 24 will be explained.

In the main routine (Figure 16), if the -1 item key is ON, you will be taken to this routine and -IKEN/F-1
Check it, and since it's No at first, turn on the CAP switch.
Check.

Thereby we check if the film is loaded and if YES we go to the CCHECK routine (Figure 28) and then C= 1 '/, =
Check 1, and if YES, check the item search switch.

If the search switch is ON, it is a misoperation condition; even if it is ON, if KENMARK /F=1, it is a misoperation condition; if KENMARK/,, -0, it is 171KEN? 1
Go to F-1.

This assumes that the stopped frame is, for example, case number 2 in FIG. 40 when searching for a case. Then, assume that you operate the -1 piece key and take out the P4 piece. At this time, the counter changes from 2 to 1. Since the counter is 1, it is an erroneous operation condition in the piece search, but in the case search, when the -1 case key is operated, P
You must return it to the l piece. Therefore, KEN

C=1. If the check for %=1 comes to NO, C-0/F
If it is NO, it will be -I KEN /, -1.

Then, register R2 is set to GO←1. DOWN-1゜RE
Input the film drive signal data W←1, and
Jump to the RUTN routine (Figure 65).

This is similar to the -1 frame routine.

And when we return from the MSRUTN routine, MOVEI
Check /F=1, if processing is in progress, select YES to move to MOVE3, if after processing, select No to check item search switch, if item search switch is OFF, go to CCHE
Check the contents of the counter in the CK routine and set C=1.
If it is child-1, go to MSEND to stop the film.

This operation is related to the gist of the present invention, and when the -1 item key is turned on after the first piece with item mark (4 in Fig. 1) is searched during the piece search, the counter is When the content becomes [0OOIJ], return the film and stop. As a result, the first piece (Kl in FIG. 1) is detected and stopped.

If C=1+-1, check the subject mark. If there is a subject mark, go to MSEND, if not, you have to move until the subject mark comes, so MOV
Go to E3.

When the item search switch is ON, only the item mark is checked without checking the contents of the counter.

Next, the MANUALJ routine shown in Fig. 25 will be explained. When coming from the main routine (Fig. 16), first check whether the manual switch is ON.
If so, each F7. shown in the figure. Reset and RESTAT
Return to If YES, check MSTP=1.

MSTP is a signal that is set when the end mark is read in manual mode. In the manual film drive, since the film drive circuit 70 (FIG. 8) independently operates the motor, this motor must be stopped when an end mark is detected. Therefore, when in manual mode, M
There is a signal called STP.

If the MSTP=1 check returns NO, MANU/
Set F and go through the CCHECK routine (FIG. 28) to check the counter. C=0. If the %-1 check is YES, the direction signal from the film drive circuit is checked, and if ADV (advance), the program jumps to the FMSTAT routine to start the film.

If it is REW, do nothing and move
Jump to 2.

If the result of checking C=0/F=1 is No, check the CAP switch ON, and if YES, the film is loaded, so set FILM/F-1 and check the direction signal. If NO, immediately go to check the direction signal.

If the direction signal is ADV (advance), the process goes to the PSRUTN routine that counts up, and if the direction signal is REW (return), the process goes to the MSRUTN routine that counts down. Then, check MOVE 1/, = 1 for each, check END+=1 when processing is completed in the feed direction, and if YES, jump to MSTPST and MS
Turn TP to "l" and stop the film drive.

When moving in the backward direction, check MOVEI/F-1 and check NO.
If so, reset END+.゛This means that when you turn the manual dial in the forward direction, detect the end mark and stop the film with MSTP←1, then turn it in the return direction, and if the last frame mark does not come, END will be sent.
/F means that it is not reset.

If MOVE 1/, = 1 check is YES, processing is in progress, so reset MOVEI/F and move
Fly to VE2. When in manual mode, I skip to MOVE2 to ignore the operation of the stop key.

In the manual mode, the film drive signal is sent to the motor 54 (depending on the direction of the manual dial 24 (Fig. 3)).
5 and 8), the manual routine only counts marks (Film Drive GO).

(DOWN, MID, and REW signals are not used).

Next, the search (SEAR) routine shown in FIG. 26 will be explained.

This routine is a routine that searches for a piece or item based on the set mark number.

First, check 5EAR/F=1. At first, the answer is No, and then it is checked whether the display register is "0000". If YES, the process goes to the OPMISS routine, and if it is NO, the process goes to the hccNT routine.

The ACCNT routine is a routine that compares the contents of the counter and the contents of the display register, as shown in Figure 66, and subtracts the contents R of the display register and the contents C of the counter, and if the result is 0, R-C. = OFF,
If the result is greater than O, set R-C>O/P.

After passing through this ACCNT routine, return to FIG.
Check C=OFF. Yes if set
Since it is S and the counter and register are equal, this is an erroneous operation condition and the process goes to the OPMISS routine.
If no, go to the 0PSTAT routine and start the film.

Then, upon returning from the 0PSTAT routine, OPMI
S child=1'! & Check L, YESZ et al. OPMISS
Go to the routine, and if No, start processing.

First, 5EAR', l-I KL, R-C>O'4=1
'f: f nick, if YES it will be the feed direction, if no
If so, it is the return direction. And if YES, E
Check NDP/F=1, if YES, OP
Go to MISS routine; if No, check FILMFF. If this check is NO, the process jumps to MOVE3, and if YES, a check is performed to turn on the switch for the 9th frame. Also, in the return direction, set REW-1 to END.
Reset F+ and check whether the 9th frame switch is ON.

If this check is NO, the speed should be reduced before the 19th frame, and if YES, the speed should be reduced before the 9th frame.

This is because if you stop it immediately from high speed, the specified piece will fly over (due to inertia), and from high speed to 19 or 9
If you slow down the speed in front of the piece, stopping accuracy will increase.

In reality, if the pieces are consecutive, 1
The 9th piece is used in special cases where the 9th piece is incorrect and the piece is flying. Furthermore, when searching for an item, as shown in FIG. 12, the 9th frame signal is input in terms of hardware. This is because the subject mark is attached to each information group, so even if the speed is slowed down before nine frames, the stopping accuracy will be achieved.

Therefore, after checking whether the 9th frame switch is ON, a comparison is made to see if the absolute value IR-CI, which is obtained by subtracting the contents of the counter from the contents of the display register, is equal to or less than 9 or 19. D
Set the OWN signal.

Then, put the data of Go-1 into register R2,
Check the output of REW, MSRUTN or P S
Jump to RU TN routine.

Then, when you return, check MOVE1/, =1, and Y
If it is ES, it is being processed, so go to MOVE3; if it is NO, it is after processing, so go through the ACCNT routine, and R-C=
Check 0/=1.

This checks whether the contents of the display register and counter match. If they match, YES.

If they do not match, the result is NO. If NO, MOVE
Go to 3. If YES, check REW=1 again and Y
If ES, go to MSEND, if NO, go to ENDRNt, R
Go to ESET 1.

Finally, the copy routine shown in FIG. 27 will be explained.

This routine is a temporary copy routine, and usually
When copying only the pieces, use only the grid/to control section shown in Figure 9.

Therefore, in FIG. 12, when the print signal is input when the copy switch 29 is ON, the print signal is input to the search control circuit 90 through the AND gate 94. When this print signal is received, the process jumps to the copy routine.

First, go through the CCHECK routine, check C=0/F=1, and if YES, return to RESTAT and c
The opy routine does not start. That is, C=
If OF/F=1, it is assumed that the film is not loaded. If NO, C0PYI; +-1
Check and the first answer is No, so C0PYF+←
1 and start timer TI.

(For further explanation, refer to the copy timing in Figure 11.) Then, timer TI is checked for time over,
If the answer is No, the stop key is checked, and if it is not turned on, the timer Tl start check is YES.

The stop key in this case is to interrupt copying (otherwise to stop the film).
If the stop key is ON here, RES'TA
Return to T.

When the timer Tl checks for time over and becomes YES, a mirror clutch OFF signal is output to keep the second mirror in FIG. 4 tilted.

Then, it waits for a paper stop signal to be input.

When the paper stop signal is input, the timer T2 is started and the timer T2 is waited for while checking the stop key until the timer T2 reaches the time limit. When the timer T2 times out, a lamp ON signal is output and the lamp 34 in FIG.
Then, after processing the +1 piece routine, RESETI (
Figure 15), the check for C0PY +-1 fails, and the process returns to CPYIO in Figure 26.

When it comes to CPYIO, set +lKOMA/, ←0, and K
Check ENMARKζ, -1, and if it is NO, turn on the reprint signal and start timer T3 with L.
After the time has elapsed, the lamp is turned off, the reprint signal is also turned off, and the vapor stop signal is checked again.

When it comes from the +1 piece routine, if there is an issue mark,
Set the output port to 0 (now the mirror OFF signal is also 0), return to RESTAT, and finish copying.

As described above with respect to the embodiments, according to the information retrieval device implementing the return control force method according to the present invention, a microfilm having an information frame without an issue mark before the first frame with an issue mark is used. After searching for the first item-marked piece in the piece search, if you want to see the first information piece, just press the key to go back one item and the first information piece will appear.
Searching indexes, lists, etc. becomes extremely easy.
