Abstract

PURPOSE:To shorten the copying time and to improve the operability, by giving the distinction among the head, the middle and the tail of each frame group with the combination of two frame marks which form different trains in the lengthwise direction of a film and therefore starting immediately the copying at the tail frame. CONSTITUTION:The 1st mark MK1 and the 2nd frame mark MK2 are added in correspondence to the head fame (e.g., B1) of each frame group KG to which a single unit of information of a microfilm 11 is recorded. At the same time, the marks MK2 and MK1 are set in correspondence to the middle frame (e.g., B2) and the tail frame (e.g., B3) respectively. These frame marks form trains different from each other in the lengthwise direction of the film 11. As a result, a reader printer can detect the frame marks to then detect the tail frame. Then informations B1-B3 can be immediately copied at and after the tail frame and in order of informations B3-B1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to microfilm used in information retrieval devices such as reader printers.

Conventionally, negative or positive microfilm as shown in FIG. 1 has been used in information retrieval devices such as reader printers.

This microfilm 1 has a starting end leader tape 2 that is attached to a take-up reel (not shown) and a terminal end leader tape 3 that is attached to a reel in the cartridge. A mark Ms (which becomes a reset mark when returning) and an end mark ME are attached.

And this microfilm 1 has a start mark M
s and the end mark ME, there is a large number of pieces K on which information is photographed and recorded at regular intervals in the longitudinal direction, and piece marks MK are attached in a row corresponding to each piece K. At the same time, a first frame mark (case mark) Mc is attached to each first frame of the frame group KG in which one unit (one item) of information group is recorded so as to form a column different from the piece mark %. ing.

Note that the piece group KG generally consists of a plurality of pieces, but there is also a kettle of one piece. In addition, in Fig. 1, At, A2°B1-Bs
, Cs-C4- indicates information recorded on each piece K.

- Then, the information retrieval device detects the frame mark MK and the first frame mark Mc ( At the same time, you can copy the information of the required pieces.

By the way, this microfilm 1 has information on the occipital piece (the last piece) of each frame group KG, for example, information A2,
There is no indication of '(H) on the pieces that recorded B3 and C4.

Therefore, in information retrieval devices, microfilm 1
When copying a unit of information, for example, information Bl, B2°B3, it is important to avoid wasting time aligning the pages after copying (
In order to do this, after searching for the frame in which information C1, which is the first frame of the next frame group, is recorded, using the first frame mark Mc, the frame is moved back and the information Bs, B2, and Bt are copied in this order.

However, searching for the first frame of the frame group following the frame group to be copied in this way and returning one frame causes problems in that time is wasted and operability is poor.

This invention has been made in view of the above points, and provides a microfilm that can shorten copying time and improve operability when copying a group of -potential information when used in an information retrieval device. The purpose is to

Therefore, the microfilm according to the present invention has the first frame mark and/or the second frame mark corresponding to the first frame, middle frame, and back frame of each frame group. By attaching the second piece marks in different rows in the longitudinal direction, the pieces can be distinguished from each other, so that copies can be made immediately from the back piece of the group of pieces to be copied.

FIG. 10 shows the first part of the microfilm. FIG. 3 is a schematic perspective view showing the configuration of a portion that detects second piece marks MKI and MK2.

In the figure, a first piece mark detector 67 and a second piece mark detector 68 are each equipped with a light receiving element such as a photodiode on the lower surface thereof, and detect microscopic images by changing the amount of incident light due to the light emitted from the lamp 50. The presence or absence of the first frame mark Mxt and second frame mark MK2 on the film 11 is detected.

FIG. 11 is a block diagram of an item search circuit for searching the microfilm shown in FIG. 2.

In the figure, the first piece mark MKI and the second piece mark MKz of the microfilm 11 are detected from the first piece mark detector 67 and the second piece mark detector 68 of FIG.
The first frame mark signal SKI and the second frame mark number SKz of high level ``H'' which are output every time f is detected are input to the AND circuit 69, respectively.

This AND circuit 69□11 is connected to the first . When both of the second frame mark signals SKI, 8 and 2 are 1H'', that is, the first and second frame mark detectors 67 and 68 both detect the first and second frame marks MKI, MKI of the microfilm 11.
The first frame detection signal Sce, which becomes high level 1H'' only when MK2f is detected, is output to the counting circuit 70.

The counting circuit 70 counts the leading frame detection signal Sc f from the AND circuit 69 and outputs the counted value to the subtraction circuit 71 .

The subtraction circuit 71 inputs the count value P from the counting circuit 7o and the leading frame number Q of a desired frame group entered using the numeric keypad 67 in FIG.

Then, this subtraction circuit 71 performs the calculation of Q=P and determines whether the calculation result is positive or negative, and while Q-P~0, the numerical value that is the calculation result and the drive signal Sv according to the determination result are It is output to the forward/reverse switch 73 via the D/A converter 72.

This forward/reverse switch 76 switches the rotational direction of a drive motor 74 that rotationally drives a film feed roller (not shown) that feeds a microfilm provided inside the film drive unit 13 in FIG. 7 in response to a drive signal SV. hand,
Switch the film feeding direction.

The drive motor 74 receives a drive signal Sv from the subtraction circuit 71.
While the drive signal Sv is being output, it rotates in the rotational direction according to the switching result of the forward/reverse switch 73, and stops when the drive signal Sv is no longer output from the subtraction circuit 71.

Therefore, the microfilm 11 is fed until the first frame of the desired frame group set using the numeric keypad 67 in FIG. 8 comes to the projection position, and the first frame reaches the projection position. Second
The piece mark detectors 67 and 68 respectively detect the first piece mark MK.
t and the second piece mark MK2'i is detected, the microfilm 11 stops running.

As a result, the first frame of a desired frame group on the microfilm 11 is projected onto the screen 12 in FIG. 6 or 9.

The 12th piece is the first piece mark MKI as shown in Figure 2.
FIG. 3 is a block diagram showing an example of a print control circuit when using a microfilm to which a second frame mark MK2 is attached.

In the figure, when the copy switch 45 and the copy switch 25 for one copy of the copy start command circuit 75 are pressed,
The copy command signal SP of high level 1H1 outputted from the ND circuit 76 is controlled to feed the microfilm 11 in the feeding direction shown in FIG. 2 (the direction in which the occipital frame is detected) until the occipital frame is detected. Film forward feeding control circuit 7
7 set/reset type fritz/flop circuit (hereinafter [
It is input to the set terminal S of 78 (referred to as S-RFFJ).

Forward drive circuit 79 of this film forward feed control circuit 77
inputs the Q output of the 5-RFF 78 and moves the film feeding drive motor 74 shown in FIG. 11 in the feeding direction of FIG. 2 only while this Q output is 1H''. Drive rotation in the direction.

Also, the Q output of the 8-RFF78 is connected to an AN that inputs the occipital piece detection signal SD from the reverse drive circuit 81 to one input terminal.
The signal is input to the other input terminal of the D circuit 80, and is input to the reset terminal R as a reset signal for the output 1s-4LFF 78 of the AND circuit 80.

This backward piece detection circuit 81 includes a first piece mark detector 67
directly from the first piece mark signal SKl, and the second piece mark signal SK2'i from the second piece mark detector 68.
The signals are input to an AND circuit 86 via the NOT circuit 82, and the output of the AND circuit 86 is output as the occipital frame detection signal SD.

Therefore, the occipital piece detection signal SD is at a high level' only when the first piece mark detector 67 detects the first piece mark MKxi and the second piece mark detector 68 does not detect the second piece mark MK2. It becomes "H".

Also, the AND of the film forward feeding control circuit 77 described above
The output of the circuit 80 is also input to a copy control circuit 85 via a delay circuit 84.

When the input of this copy control circuit 85 becomes 'H', the 9th copy control circuit 85
- Each part involved in copying the microfilm threaded in the figure is controlled in a predetermined order to make a copy of the microfilm, 1" film, and when the copying operation is completed...
A copy end signal PE of level ``H'' is output.

Furthermore, the output of the AND circuit 80 is converted into a copy command signal Sp from the AND circuit 79 via the delay circuit 84.
S-R is input to the reset terminal R, and is also input to the set terminal S of the FF86.

Then, the Q output of this 5-RFF86 is the AND circuit 6
The leading frame detection signal 5cft from 9 is input to the other input terminal of the AND circuit 87, and its output 1AND circuit 7
The copy command signal Sp from 6 is input to the set terminal S of 8-RFF88 which is input to the reset terminal R.

Then, the copy end signal PE from the copy control circuit 85 is outputted via an AND circuit 89 which inputs the Q output of the 5-4L FF 88 to the other input terminal, and for example, the completion of the copy operation is displayed on a display section (not shown). .

Further, the copy end signal PK from the copy control circuit 85
is input to the other input terminal of the film backward feeding control circuit 91, which controls feeding the microfilm 11 one frame in the backward direction as shown in FIG. 8=, R, input to set terminal S of FF92.

Reverse drive circuit 93 of this film backward feed control circuit 91
inputs the Q output of 5-4L FF92 and calculates this Q
Only while the output is H', the drive motor 74 for transporting the film shown in FIG. 11 is rotated in the direction of moving the microfilm 11'jk in the return direction of FIG. 2.

In addition, the Q output of the 5-RFF 92 is inputted to the other input terminal of an AND circuit 94 which inputs 2 to one input terminal of the second frame mark signal 8 from the second frame mark detector 68. The output 1s of the AND circuit 94 is inputted to the reset terminal R as a reset signal of the RFP circuit 92.

The output of the AND circuit 94 is inputted via the delay circuit 95 to the set terminal S of the copy control circuit 85 and 5-RFF 86 described above.

Next, a second print control circuit configured as shown in FIG.
The operation of copying information of one unit of frame group of the microfilm 11 shown in the figure will be explained.

First, a search for microfilm 11 was conducted.
For example, assume that information B1 recorded on the first frame of a frame group KG in which information B1, B2, and Bs shown in FIG. 2 are recorded is projected on the screen 12 of the reader printer.

In this state, when the operator presses the copy switch 45 for one item and then presses the copy switch 25, the copy command signal Sp
5-RF'F of the film forward feed control circuit 77 by
When 78 is set, K and S-RFF 86 and 88 are also reset.

When the 8-RFP 7B is set and its Q output becomes ``H'', the forward drive circuit 79 rotates the drive motor 74 in the film feeding direction, so that the microfilm 11 is fed in the feeding direction shown in FIG. Ru.

When the occipital frame recording the information B3 of the final page of the microfilm 11 comes to the projection position, the backward drive circuit 81 outputs the occipital frame detection signal 8D.

As a result, the output of the AND circuit 80 becomes 1H'',
S-R, FF78 is reset and its Q output is '''L
'', the forward drive circuit 79 stops the drive motor 74 and stops the microfilm 11 at that position.

Then, after a predetermined period of time has elapsed since the output of the AND circuit 80 became ``H'', that is, after the microfilm 11 completely stopped, the output of the delay circuit 84 became ``H''.

Therefore, the copy control circuit 85
Information B of the resolvable occipital piece in which the information to be copied in No. 1 is recorded
3 starts the copy operation.

At this time, the 8-RFF86 is set and its Q output becomes 1H'', but at this point, the top frame detection signal Sc is not output from the AND circuit 69, so the 5-RFP8
8 is not set.

When the copying of information B3 on the microfilm 11 is completed, the copying control circuit 85 outputs a copying end signal PE, and since the 5-RFP 88 is in the reset state at this time, the copying end signal PK is outputted via the AND circuit 90. The signal is input to the SR'FF 92 of the film backward feeding control circuit 91.

As a result, the 8-RFP 92 is set and its Q output becomes 1H'', and the reverse drive circuit 96 is activated by the drive motor 74.
Since the microfilm 11 is rotated in the film return direction, the microfilm 11 is sent in the return direction as shown in FIG.

Then, when the frame recorded with information B2f on the microfilm 11 comes to the projection position, the second frame mark detector 68 detects the second frame mark MK2 and the frame mark signal 5x
Output zl.

As a result, the output of the AND circuit 94 becomes 1H'',
Since the 8-RFP 92 is reset and its Q output becomes 1L', the backward drive circuit 96 stops the drive motor 74 and stops the microfilm 11 at that position.

Then, after a predetermined time has elapsed since the output of the AND circuit 94 became 2H'' and the microfilm 11 completely stopped, the output of the delay circuit 95 becomes ``H''.

As a result, the copy control circuit 85 controls the microfilm 1
1, and when the copying operation is completed, a copying end signal PEi is output. - At this time as well, the 8-RFP 88 operates as in the reset state, and the microfilm 11 is fed in the return direction as shown in FIG.

Then, when the first frame recorded with information Bsf moves to the projection position, the second frame mark detector 68 detects the second frame mark MK2'i, so the microfilm 11 stops at that position and stops at that position. Similarly, the copying operation of the information B1 is performed, and the copying operation ends when the copying of the information B1 of the first frame is completed.

At this time, since the AND circuit 69 is outputting the first frame detection signal Sc, the output of the AND circuit 87 becomes H# and 5
-RFP88 is set, its Q output is H'', and the available output is 1L''.

Therefore, when the copying operation of the information Bl recorded in the first frame of the microfilm 11 is completed, the copying control circuit 85
The copy end signal PE output from the AND circuit 89
The information is input to a display unit (not shown) via the .

Thereby, the display section displays that the copying of the desired digestible information B1, B2, and Bs on the microfilm 11 has been completed.

After that, information Bt on the microfilm 11.

If you want to copy Bz, Bs f, you can operate the copy switch 25 again, and if you want to copy other decipherable information, you can search for that decipherable information and operate the copy switch 25.

In this way, the operator can obtain a copy of the desired comprehensible information with the pages aligned by simply operating the copy switch 25 once after searching for the comprehensible document in which the information desired to be copied is recorded. .

In this case, it is not necessary to search for the first frame of the next possible frame after the one in which the information desired to be copied is recorded and move the microfilm back one frame.

FIG. 13 is a block diagram similar to FIG. 12 showing another example of the print control circuit.

This embodiment is different from the embodiment of FIG. Count the number of times and calculate this count value CA
The comparison circuit 98 compares the number of copies CB set by the number of copies dial 43 in FIG.
p is input to the set terminal S of the S-RFF 78 of the film advance control circuit 77.

In this way, each time a desired copy of the microfilm 11 is completed, the copy end signal PE from the copy control circuit 85 is sent to the counter 97 via the AND circuit 89.
until the number of copies set by the number of copies dial 46 is reached.
Since 5-RFP78 is set by , it is the desired piece.

The group copy operation is repeated the required number of times.

Therefore, by operating the copy switch 25 only once, the desired number of decipherable copies can be obtained, making the operation extremely simple.

In addition, when using the microfilm shown in Fig. 6, Fig. 4, and Fig. 5, or the aforementioned microfilm not shown in the figure, in place of the microfilm shown in Fig. 2, the printing time depends on the microfilm used. What is necessary is to change the configuration of the control circuit.

Furthermore, in the above embodiment, information is recorded from the start mark side of the microfilm to the beginning, but information may be recorded sequentially from the end mark side, and in this case, the microfilm is The sending direction may be opposite to the above-mentioned direction.

As explained above, by using the microfilm according to the present invention, it is possible to shorten the copying time and improve operability when copying a unit of information group of the microfilm in an information retrieval device.
