Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information retrieval device such as a reader printer capable of retrieving desired information items and information frame groups on microfilm.

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 tape 1a that is hooked to a take-up reel (not shown) and a trailing end leader tape 1b that is hooked to a reel in the cartridge. Mark (becomes a reset mark when returning) M8. Add the end mark ME.

A large number of information cards K, in which information is photographed and recorded at regular intervals, are arranged on the film 1 between the two marks, and a piece mark MK is attached corresponding to each information card. Item mark M corresponding to the first frame of the recorded information frame group (generally consists of multiple frames, but there are cases where a single piece contains information for one item) KG. is attached.

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 case search (search for each group of information frames for one case).
It is now possible to do this.

In other words, the key to send information piece K by 1 frame + 1 piece key, the 11 piece key to move back 1 piece, the key to send 1 group (for 1 item) of information frame group KG + 1 item key, and the 11 item key to return 1 group (for 1 item). .

A numeric keypad for entering the piece number or item number that you want to automatically search, a register as a search number storage means for storing the entered search number, a search key as a inspection command means for starting the automatic search, a piece search and search switch,
A mark detector that detects piece marks and subject marks on microfilm.

It is equipped with a counter as a mark counting means that counts the piece marks or item marks based on the detection signal, and a display device that displays the counted value.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 forward and return one frame, and forward and return one item. In addition, you can automatically search for the piece number in the piece search mode and the item number in the item search mode by entering them in advance with the numeric keypad. is now possible.

In the case of automatic search, when the search key is operated, the microfilm is moved so that the count value of the counter matches the search number stored in the register, and stops when the count value matches the search number stored in the register.

Further, when the microfilm 1 is fed to near the end, an end mark MF is detected, and the feeding movement of the microfilm is thereby stopped.

In such an information retrieval device, when the count value of the mark counting means is the maximum countable value, for example, in the case of a 4-digit counter, the count value is l'-9999J, +1
When you operate the frame key, when the microfilm is fed one frame and the next frame mark is detected, when the microfilm is fed one frame and the next frame mark is detected, the counter value will change to ``00''.
00. When the next piece mark is detected during the piece search, it becomes -HIQ 000J, and then the piece marks are counted and stopped until the next piece mark is detected.

In this way, if the count by the mark counting means exceeds the maximum countable value, the number of the information frame or information frame group on the microfilm will naturally differ from the count value (displayed value). .

The present invention has been made by focusing on the above-mentioned problem, and it is possible to perform a search within the countable range of the mark counting means in the above-mentioned information retrieval device, and to prevent a search exceeding the maximum countable value. The purpose is to issue a warning and notify the operator if an attempt is made.

Therefore, in the information retrieval device according to the present invention, when the count value of the mark counting means reaches the maximum value that can be counted, the key to send one information frame (+1 frame key) or the key to send one group of information frames ( The above object is achieved by providing an erroneous operation determination means that outputs an erroneous operation signal to prevent the microfilm from moving when the +1 key) is operated, and an erroneous operation warning means that issues a warning when the erroneous operation signal is output. It is something to do.

．． 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. The film 11Ii scraped out of the cassette 50 by the thread roller 53, the drive roller 55 and the press roller 51.・
go in between. When the film 1 is wedged between the rollers 55 and 56, the cabstance inch (hereinafter referred to as 1CAP switch) 57 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. Then, the film 1 passes through the film dart 58 and is wound around the reel 59. 60 is a film holding arm.

Then, when the start mark is read by the mark detector described later, it will move from medium to high speed (search key when searching for pieces after the 20th frame) or low speed (+1 piece key, +1 item key, pieces within 19 pieces). (search key when searching). Thereafter, when the mark detector detects a predetermined mark, the advance of the film 1 is stopped, and the lens 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 Mc on the microfilm 1 illuminated by the light of the lamp 34 are exposed to the mirror 61.6.
2, is magnified (doubled) by lenses 63 and 64, is reflected by mirrors 65 and 66, and reaches a piece mark detector 67 and an object mark detector 68. Note that the information on that piece is projected onto the screen 2 in FIG. 4 through a projection lens 66.

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: On/off signal of the CAP switch 57. When the film force is inserted between the drive roller 55 and press roller 56 in Fig. 5. Turns 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 '1#' in the forward direction and 10'' in the return direction.

FIG. 9 shows the print control circuit.

According to the print control circuit 80, when the print switch 8 shown in FIG. A copy of the information frame is made and discharged to a copy receiver 5.

The mirror clutch OFF signal, lamp ON signal, and reprint signal are signals that are input from the search control circuit shown in FIG. , 1/tos inch is input instead of being manipulated to copy the next piece.

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 90 uses a one-chip microcomputer having a central processing unit (CPU), ROM as a program memory, RAM as a data memory including the aforementioned counters and registers, 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 at the same time.

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 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 input via the R dart 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 page 74-stop signal PST, which is generated 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.

Furthermore, sensors AT, B1*A2+B2 of the piece mark detector 67 and sensor A3. of the piece mark detector 68 shown in FIGS. 6 and 7. The output signals of Bs are respectively input to the mark preprocessing circuit 95 to discriminate 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 the loaded microfilm is positive.

As for the output system, MID (medium speed) is used as each realm drive related output to the film drive circuit 70 in FIG.
, Go (high speed), DOWN (low speed).

REW (return), MSTP (motor stops during manual operation)
output each signal.

1. Mirror clutch OFF signal and lamp ON signal to print control circuit 80 in FIG.

Outputs a reprint signal.

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

Also, in the piece search mode, piece number data is output, and in the item search mode, the item number data (counted value by a counter in CRAM or value entered in a register by a numeric keypad) is output, decoded by a decoder 98, and outputted by a 7-segment LED.
is displayed on the four-digit numerical display 27. In this case, each digit of the numeric display 27 is sequentially and dynamically displayed by the switching signal Sc.

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 7 in FIG. 6 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 arranging routine and sequentially sets the values in the registers.

If the numeric key 20 is not operated, then the search key 16, +1 piece key 14. -1 piece key 15° + 1 item key 22. The -1 item key 26 is checked in sequence, and if any one is operated and turned on, the search routine, +1 piece routine, -1 piece routine,
+1 routine.

The process proceeds to either the -1 item routine, but when proceeding to the +1 piece routine or 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.

Then, in the mistake check routine, as shown in Fig. 12, it is checked whether the count value of the counter is the maximum value that can be counted (in this example, "9999"), and if NO, the main routine shown in Fig. 11 is performed. The process returns to , and proceeds to the +1 frame routine or +1 item routine, where the microfilm is advanced by one frame or one item and the counter is incremented.

If YES, it is determined that it is an erroneous operation and the erroneous operation signal 5Ml5S is sent.
is output and the process proceeds to the process of sounding the buzzer 97 shown in FIG. 10 to issue a warning. Since the process does not proceed to the +1 frame routine or the +1 item routine, the microfilm is not moved.

In this way, the search control circuit checks the contents of the counter when the +1 frame key or +1 item key is operated, and if it exceeds the maximum countable value, it issues an erroneous operation signal without moving the microfilm. The function is a means for determining erroneous operation.

When it is determined that an erroneous operation has occurred, the internal timer is first set and started, and the buzzer is turned on. Thereafter, the buzzer continues to sound until the timer 7Z times out, at which time the buzzer is turned off and the process returns to the start of the main routine shown in FIG. 11.

In this way, if the +1 frame key or +1 item key is operated when the count value of the counter is at the maximum value that can be counted, the buzzer will sound without feeding the microfilm, and the operator will be able to quickly correct the erroneous operation. This will prevent you from making incorrect searches.

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

Next, another embodiment of the present invention in which the mark counting means and the erroneous operation determining means are provided outside the search control circuit will be described.
This will be explained using figures.

Reference numeral 100 designates a counter as a mark counting means, which inputs a piece mark signal when searching for a piece, and inputs a piece mark signal when searching for one piece, counts the count, and displays the count on the numeric display 27 in FIG.

101 is an erroneous operation determination means, in which the count value of the counter is the maximum countable value (r99 in the case of a 4-digit decimal counter).
99J), a counter check circuit that outputs (IMf: % 1#), +1 piece key 14 and +1 item key 22
An OR circuit 103 that takes the OR of each operation output (which becomes '1'' when operated), and an AND that takes the output of this OR circuit 106 and the output of the counter check circuit 102.
The circuit 104 is configured by a circuit 104.

The counter check circuit 102 is a kind of digital comparator, and compares the count value of the counter 100 with the maximum value that can be counted, for example, "9999J (if the counter output is a binary code, [binary code equivalent to 9999J])". , outputs 11# when both match.

Therefore, when the count value of the counter 100 is the maximum value that can be counted, the output CM of the counter check circuit 101 is '1#, and in that state, the +1 frame key 14 or the +1 item key is pressed. 22 is operated, the OR circuit 103
Since the output of is 11'', the output of AND circuit 104 is 11#.

The erroneous operation determination means 101 outputs the erroneous operation signal 5Ml5B.

This erroneous operation signal 5urss is input to the search control circuit 90 shown in FIG. 10 to inhibit the movement of the microfilm, and the timer circuit 105 is triggered to output 11" for a certain period of time.

This turns on the transistor 106 and operates the buzzer 97 to issue a warning for a certain period of time.

Note that, as in the previous embodiment, something other than a buzzer can be used as the erroneous operation warning means.

As described above with respect to the embodiments, when the information retrieval device according to the present invention is used, the count value of the mark counting means corresponding to the number of the information frame or information frame group on the microfilm becomes the maximum countable value. If the key to send one information frame or the key to send one group of information frames is operated while the user is searching, the microfilm will not move and a warning will be issued, so the operator will immediately take notice and will not search further. Therefore, there is no possibility that the frame number of the information frame that is actually being searched and the count value (display value) of the mark counting means differ.
