Abstract

PURPOSE:To improve operability by detecting and storing an end mark added to the final stage part of a microfilm, and giving an alarm when a frame or subject advance is to be made. CONSTITUTION:A start mark MS (used as a reset mark during rewinding) and an end mark ME are added to connection parts between the start and end stage parts of a microfilm 1 and leader tapes 1a and 1b. When the microfilm 1 is wound from a film reel until the end mark ME is detected, the detection of the end mark ME is stored in a storage device. In this state, if an operator tries to make a frame or subject advance of the microfilm, an erroneous operation signal is generated. Consequently, the microfilm 1 is rewound until the start mark MS is detected. Thus, operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information retrieval device such as a league printer capable of performing frame retrieval for retrieving each information frame of a microfilm and item retrieval for retrieving a group of information frames for each item.

For example, a negative or positive microfilm as shown in FIG. 1 is used in such an information retrieval device.

This microfilm 1 has a starting end leader Tezo 1a which is secured to a take-up reel (not shown).

Car) The terminal end part attached to the reel in the IJ joint is connected to the reel tape 1b', and the connection part has a black start mark (which becomes a reset mark when returning) Ms,
It is attached to the end mark ME'.

A large number of information frames K are provided on the film 1 between the two marks, and information is photographed and recorded at regular intervals, and a frame mark MK is attached corresponding to each information frame, and information for one item is recorded. An item mark Me is attached corresponding to the first frame of the information frame group KG (generally consisting of a plurality of frames, but one frame may contain information for one item).

Then, the information retrieval device detects the piece mark MK and the subject mark Me of this micro-swim 1, and performs a piece search (search for each frame) and a subject search (search for each information frame group for one subject).
It is now possible to do this.

In other words, send the information piece K by 1 piece + 1 piece key, move back 1 piece with the 11 piece key, send 1 piece of information piece KGi + 1 piece key, move back 1 piece with the 11 piece key, enter the piece number or piece number you want to automatically search for. Numeric keypad for entering numbers.

Equipped with a search key to start an automatic search, a changeover switch for piece search and item search, a counter and a display to display the count value, etc. In the piece search mode, the counter changes to the piece mark M.
K is counted and displayed on the entire piece number display, and in case search mode, the counter counts the case mark McF and displays the case number on the display.

In either mode, you can forward and return one frame, and forward and return one item. In addition, you can set the piece number in the piece search mode and the item number in the item search mode using the numeric keypad automatically (C search). is now possible.

When the end mark ME is detected, the microfilm feeding drive is stopped.

In that state, if you press the +1 frame key or the +1 item key, it is a mistake because you cannot send any more microfilm, but with conventional information retrieval devices,
In such a case, even if the +1 frame key or +1 item was operated, the microfilm would not move.

Therefore, the operator may not notice the erroneous operation and waste time.

This invention was made to solve the above-mentioned problem, and when the +1 piece key or +1 item key is operated after the end mark is detected, a warning is issued and the operator is informed that the operation has been erroneous. The purpose is to inform users and improve operability.

Therefore, the information retrieval device according to the present invention includes a storage means that stores the end mark provided near the end of the microfilm when it is detected, and a third storage means that stores the detection of the end mark. By providing an erroneous operation determination means that uses an erroneous operation signal when the +1 piece key or the +1 item key is operated in a state where the button is pressed, and an erroneous operation warning means that issues a warning based on the erroneous operation signal,
This achieves the above objectives.

When the exposure for a certain period of time is completed, the lamp 34 is turned off and the photosensitive paper 40 is moved again toward the developing section 47. The photosensitive paper 40 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. Also,
When the exposure is completed, the mirror clutch 41 is turned on, and the second mirror 387- returns to its original position.

Note that 49 is a reflecting plate that reflects the light emitted by the lamp 64 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゜11 items key 22. By operating the feed direction of the manual dial 24, the solenoid 52 is turned on, the thread roller 53 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. The film 1 scraped out of the cassette 50 by the thread roller 53 enters between the drive roller 55 and the press roller 56. When the film 1 is caught between both rollers 55 and 56, the Cabstan switch 57 (hereinafter referred to as "rCAP switch") is turned on.

When the CAP switch 57 is turned on, the solenoid 52 is turned off, and the film feeding force is applied from the drive roller 55. and.

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

Then, when the start mark is read by the mark detector described below, the speed ranges from medium to high speed (search key when searching for pieces after the 20th frame) or low speed (+1 frame key, +1 item key, within 19 frames). Search key when searching for pieces) K switches. Thereafter, when the mark detector detects a predetermined mark, the advance of the film 1 is stopped, and the lamp 34 is turned on to project the stopped frame.

The mark detection section is constructed as shown in FIG.

Then, the frame mark MK and the subject mark Me of the microfilm 1 illuminated by the light of the lamp '34 are reflected by the mirror 61.6.

As shown in FIG. 7, the piece mark detector 67 is a sensor AT.
+ A2 + 13+ r B2 ,
It is equipped with an object mark detector 68I'i and a sensor As+Bs'. Each sensor is specifically a photodiode.

The piece mark detector 67 also serves as a start mark detector and an end mark detector, and its sensors A+ and B+ produce a piece mark signal for piece mark count/to.
2 + B2 and At l B1 produce a start mark signal, an end 9 mark signal, and a reset mark signal (when the microfilm is fed in the return direction and a start mark is detected). Sensor As of the subject mark detector 68
+ Bs /d signals are generated.

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

FIG. 8 shows a film drive circuit and its input and output signals, including the microfilm 1.

The output signal of the film drive circuit 70 controls the driving speed and feeding direction of the drive motor 54 (M+) shown in FIG. 5, and controls the on/off state of the solenoid 52 for feeding.

Table 1 shows the relationship between the input signal of the film drive circuit 70 and the film advancing direction and speed.

Each input signal in FIG. 8 of Table 1 and the above Table 1 is as follows. Note that the film is not fed under the conditions marked in Table 1.

11- GO: High speed signal MID: Medium speed signal DOWN
: Low speed signal REW : Return signal MSTP : Signal to stop the motor when using the manual dial CAPSW : The on/off signal of the CAP switch 57 causes the film to bite between the drive roller 55 and press roller 56 in Fig. 5. It turns on when it's on.

MDS: A signal that changes the rotational speed of the motor 54 according to the position of the manual dial when it is moved.

On the other hand, the direction signal DS in the output signal is 11'' in the forward direction and '0'' in the return direction.

In addition, the solenoid 52 is connected to the thread roller 5 shown in FIG.
3 is a solenoid for contacting film 1,
When the CAP switch 57 is off, the solenoid 52 is turned on, and when the CAP switch 57 is on, the solenoid 52 is turned off.

FIG. 9 shows the print control circuit.

12- When the print switch 8 shown in FIG. 3 is turned on by this print control circuit 80vc, the motor 81 (M2) 2 for transporting the photosensitive paper is started, and as explained in FIG. 'Start at '.

At the same time, the mirror clutch 41vil 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 43 and stopped at an exposure surface 46 on a vacuum belt 45. At this time, the paper stop signal PST (Figure 9)
is output, and at the same time the lamp 34 is turned on for exposure.

When the exposure is completed, the lamp 34 is turned off, the photosensitive paper 4° is fed again, the mirror clutch 41 is turned on, the second mirror 38 is returned, and the copy is ejected 5vc.

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 38 falls.

When the photosensitive paper 40 stops at the exposure surface 46, an E/Ya-stop signal PST is output, and the lamp 34 is turned on to perform exposure. When the exposure is finished, Lande 3
4 goes out, the photosensitive paper 40 is developed, and the copy tray 5vc is turned off.
be discharged.

In this case, in the copy mode, after the print signal P is output and the second mirror 38 is tilted.

When a mirror clutch OFF signal is received from the search control circuit shown in FIG. 12, which will be described later, the mirror clutch 41 is turned off separately from the print control circuit 80.

Then, after the exposure is completed by the stop signal and the photosensitive paper comes out from the exposure surface 46, a signal for lighting the lamp 34 is input and the lamp '34 is lit, and a signal from the search control circuit shown in FIG. 10, which will be described later, is input. Advances the frame of microfilm 1 by one frame.

After that, the reprint signal is sent to the print control circuit 8.
0, the photosensitive paper 40 starts again and complete exposure is performed, and when the photosensitive paper 40 comes off the exposure surface, the frame is advanced by one frame, and when the sensitivity mark Me is present at this time, the mirror clutch OFF signal is turned off. , the mirror clutch 41 is turned on, the second mirror 38 returns to its original position, and the copying process is completed.

FIG. 10 is a diagram showing the relationship between the search control circuit and its input/output signals in this embodiment.

This search control circuit 90Fi uses a one-chip microcomputer having a central processing unit (CPU), ROM as a program memory, 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 switch 91 is a switch that is turned on when the manual dial 24 shown in FIG. 3 is rotated.

15-9 frame switch 92 is a switch inside the machine, and is a frame number selection switch that changes the film speed from high to low during retrieval. When the 9th frame 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 this 9th frame switch 92 is off, when the item search switch 28 is on, the switch is set before the 9th frame.
Signals from both switches are inputted via an R gate 93.

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

Furthermore, from the print control circuit 80 in FIG.
A 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 which is ANDed with the output of the copy switch 29 so that it is input only when the copy switch 2916 is on.

Further, the output signals of the sensor A+ * B+ + A2 + B2 of the piece mark detector 67 and the sensor As + B3 of the subject mark detector 68 shown in FIGS. 6 and 7 are input to the mark preprocessing circuit 95, respectively. to identify each mark,
A start mark signal, an end mark signal, a reset mark signal (a start mark detection signal when the microfilm is sent in the backward direction), a frame mark signal, and an item mark signal are 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 an output system, the film drive circuit MSTP shown in Figure 8 is used.
Outputs each signal (motor stops during manual operation).

Also, print control circuit g in FIG.

to, mirror clutch OFF signal, lamp oN signal.

Outputs a reprint signal.

In addition, if there is an erroneous operation on the operator, an erroneous operation signal 5Ml5sl is output and a buzzer 97 is sounded to give a warning.

In addition, in piece search mode, piece number data is output, and in case search mode, piece number data (counted value by a counter in RAM or set value by a numeric keypad) is output, and decoded by a decoder 98 into 7 segments). It is displayed on the digit number display 27. In this case, by the switching signal Sc.

Each digit of the numeric display 27 is dynamically displayed in sequence.

Next, during the operation of the search control circuit shown in FIG.
This will be explained with reference to the operational flowchart shown in the figure.

FIG. 11 shows an outline of the main routine, which starts from the start when the power switch 7t in FIG. 3 is turned on.

First, it is checked whether the item search switch 28 is on, and if it is NO, it is the piece search mode, so the counter is operated as a piece counter.

If YES, it is the case search mode, so the counter is operated as a case counter.

Next, check whether the numeric keypad 20 is on, and press Y.
If it is S, the program jumps to the numeric digit routine and sets the digits in the registers one after another.

If the numeric keypad 20 is not operated, then the +1 piece key 14. -1 piece key 15. +1 item key 22° -1 item key 2
3. Check the search keys 16 one after another, and if any is operated and turned on, press + to carry out that process.
1 piece routine, -1 piece routine, +1 routine, -1
Proceeds to either the subject routine or the search routine, but +1
When proceeding to the piece routine and the +1 item routine, the mistake check routine according to the present invention is passed.

In addition, manual routine and rewind routine.

The copy routine and the like are omitted from illustration.

19- Also, one of the clip-flop circuits (F/P) in the RAM of the search control circuit 90 is allocated as a storage means for storing end marks when they are detected.
Hereinafter, this will be referred to as IENDF'/F.

This ENDF/F' is set to '1#' when end run 1 processing as shown in Fig. 12 is performed in the +1 frame routine and +1 item routine of Fig. 11 and the end mark is detected. Become.

Also, in the -1 piece routine and -1 case routine, the 13th
End run 2 processing as shown in the figure is performed, and when a piece mark is detected, it is reset to 0''.

In other words, when the end mark is detected during film advance direction, ENDF/F is set, and when the film is returned, the frame mark is first detected (the frame mark attached to the last frame in the film advance direction). When detected, ENDF/
F is reset, and even if a piece mark is detected thereafter, it will remain in the reset state because it has already been reset.

Then, in the mistake check routine, as shown in Fig. 14, 20-, it is checked whether or not this ENDF/F is set. If it is not set, the routine returns to the main routine and proceeds to the +1 frame routine or the +1 case routine. .

If ENDF/F is set ('1'), it is determined that an erroneous operation has occurred, and the process proceeds to a process for sounding a buzzer for a certain period of time to issue a warning. This corresponds to the erroneous operation determination means in this invention.

First, set and start the internal timer,
Turn on the buzzer 97 in FIG. Thereafter, the buzzer continues to sound until the timer times out, and when the time expires, the buzzer is turned off and the process returns to the start of the main routine in FIG.

In this way, when the end mark is detected while feeding the microfilm, ENDF/F will be set and stored, and if the +1 frame key or +1 item key is operated in that state, the buzzer will sound. The sound makes it possible for the operator to immediately notice an erroneous operation and take appropriate measures.

Note that the erroneous operation warning means is not limited to a buzzer, but may also be a warning means using a visual display IC such as a lamp or a character, or a sound warning means using a voice synthesizer or the like.

Next, an embodiment will be described with reference to FIG. 15 in which the storage means and erroneous operation determination means of the present invention are realized outside the test control circuit using a microcomputer.

Reference numeral 100 designates a set/reset type Flinde-70 Tsuzo circuit (hereinafter abbreviated as 1'-5-RF/FJ) as a storage means, which corresponds to the ENDF/F in the above-mentioned embodiment and is set by an end mark signal. and is reset by the piece mark signal.

Therefore, this S-RF/F is set when the end mark ME is detected while feeding the microfilm, and the Q output becomes 11", which is stored.
Then, the microfilm is returned by operating the -1 frame key, -1 item key, or the search key after entering the number in the return direction.

When the first piece mark is detected, it is reset and the Q output becomes 10". From then on, when a piece mark is detected, 101 is an erroneous operation determination means, which detects the output signal by operating the +1 piece key 14 and +1 item key 22. An OR circuit 102 that takes an OR, and the output of this OR circuit 102 and the Q of the S-RF/F 100.
It consists of an AND circuit 106 that performs AND with the output.

Therefore, when the +1 frame key 14 or the +1 item key 22 is operated while the 5-RF/F100 is set, the output of the %AND circuit 103 becomes 'l'', which is output as the erroneous operation signal SMILs.

This erroneous operation signal 5Ml8B triggers the timer 104 and makes the output high level for a certain period of time, so the transistor 105 is turned on and the buzzer 97 is activated to issue a warning.

After operating the microfilm in the direction of return and S-RF/F being reset by the first frame mark, the return of the film is stopped using the stop key 17, for example, and then the +1 frame key or +1 item key is operated. In this case, the system operates normally without issuing any erroneous operation warning.

=23- As described above in the embodiment, if the information retrieval device according to the present invention is used, the +1 frame key or the +1 item key is operated after the microfilm has been fed near the end and the end mark has been detected. In this case, a warning is issued for an erroneous operation, which allows the operator to immediately notice the error and perform appropriate operations such as returning the film, improving operability and eliminating wasted time.
