CONSTITUTION:The masks assigned in accordance with respective information of an information recording medium are detected by a frame mark detector 9 and its outputs are counted up by a counting circuit 26. Two addresses inputted from an input device 20 are compared with the counted value of the counting circuit 26 by comparators 30, 31 and the compared results are outputted to a film driving part 35 to move a recording medium so that information is successively arranged in the descending order of addresses inputted from the input device 20. A printer driving part 36 is driven so that the information arranged on the copying position is successively copied.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a search copying apparatus that searches for desired information in an information recording medium such as a film or a disc, and automatically copies the information.

[Technical background and purpose of the invention]

Conventionally, some automatic film search devices have been added with a copying function, but when copying multiple pieces of desired information, two types of marks are placed on the film: an item mark is placed at the beginning of each information group; A frame mark is provided for each piece of information, and by detecting the subject mark and the frame mark, the information group of a desired subject is copied in page order. This method has the disadvantage that two types of marks must be provided on the film, making it impossible to use a film with only one type of mark, and that it takes a long time to complete copying.

SUMMARY OF THE INVENTION An object of the present invention is to provide a search copying device that can automatically obtain copies of a desired group of information arranged in page order using a recording medium having marks attached to each piece of information. shall be.

〔Example〕

The present invention will be explained below with reference to the drawings.

FIG. 1 shows a microfilm reader printer to which the present invention is applied, in which a microfilm F is wound into a roll around a film winding shaft inside a cartridge 1.
It is automatically sent out of the cartridge 1 by the capstan roller 2 and the pinch roller 5, and the guide rollers 4 and 5
The film is guided by the winding reel 6 and wound onto the winding reel 6. The microfilm F is illuminated by the lamp 7 at the copying position (illumination position), and the nine films are illuminated. The information is projected by an optical system (not shown) onto a screen of a part of the υ reader, a photoreceptor of a part of a printer, or an image pickup device such as a COD.

On the microfilm F, a frame mark m1 is attached to the side of each frame in which information is recorded, and information is recorded in the order of the youngest pages from the leading edge of the film.

m2 is a case mark attached to the side of the first frame of each information group. A mark detector 9 is placed near the copying position and optically detects the frame mark m1 on the film.

The film take-up shaft and take-up reel 6 in the IJ screw 1 are connected to a film drive motor, and when the film is wound onto the take-up reel 6, the take-up reel 6 is driven by the motor, and the film is transferred to the cartridge. When rewinding to 1, the film winding shaft in the cartridge is driven by a motor.

FIG. 2 shows a search and copy circuit, in which numeral keys 20 are used to enter the frame number ("address number") of desired information;
An input device having a copy button, 21 and 22 a memory for storing frame numbers input to the input device 20, and 25 a comparator for comparing the magnitude relationship between the frame numbers stored in the first memory 21 and the second memory 22. Then, the larger frame number is transferred to the second Lujistar 24, and the smaller frame number is transferred to the second
Transfer to register 25. 26 is a counting circuit that counts a high level (hereinafter referred to as H) mark signal M output when the frame mark detector 9 detects a frame mark;
A switching signal inputted from the terminal 26' causes the state to be switched to addition or subtraction depending on the film feeding direction.

In this embodiment, the counting circuit 26 is in an addition state when the film is fed in the winding direction onto the take-up reel 6, and is in a subtraction state when the film is fed in the direction in which it is unwound onto the take-up reel 6. Become.

50 and 51 are comparators, and the second comparator 50 is the second comparator.
The value of 4 is compared with the value of the counting circuit 26, and when the two do not match, the film drive signal FD of H from the terminal is outputted.
When both match, film stop signal F from terminal C to H
8. Output copy signal P8 and set signal BT.

Further, the fifth comparator 51 compares the value of the second register 25 and the value of the counting circuit 26, and if the two do not match, the
When the two match, an H signal AC) is output from the terminal e.

FF is the second. The flip-flops, AND1 and AND2, which control the operation of the fifth comparator 30.51 are AND gates which control the operations of the film drive section 35 and the printer drive section 56. When the flip-flop FF is reset, the second comparator 50 performs a comparison operation, and the fifth
The comparator 51 is controlled not to perform a comparison operation, and when set, the fifth comparator 51 is controlled to perform a comparison operation, and the second comparator 50 is controlled not to perform a comparison operation.

34 indicates a differentiating circuit, and when the mark signal MA rises, K
Outputs an H signal. A film drive section 55 includes a rewind motor that drives the film winding shaft in the cartridge 1 and a take-up motor that drives the take-up reel 6, and either one of the motors is selectively driven. Reference numeral 56 denotes a printer drive unit which, when a copy signal Pa is input, drives the printer, copies the information of the frame placed at the copy position, and discharges the copy paper into a tray with the copy image forming surface facing upward. . The copy sheets are stacked one on top of the other and are ejected.

Next, the operation of the above device will be explained. Now, assume that each frame from a desired frame number A to frame number B (B)A) is to be searched and copied. The frame with frame number A has information with a lower page threat number than frame number B, and
Information is recorded in page order from frame number B to frame number B.

First, input frame numbers A and B into the input device 20 and press the copy button to command start of search copying.
B is the first. It is stored in the second memory 21.22. 1st
The comparator 25 compares the magnitudes of the numbers stored in the memos IJ-21' and 22, and stores the larger frame number B in the register 24 and the smaller frame number A in the second register 25.
Transfer to.

After the transfer is completed, a reset signal RT is output from the terminal a, and the shift flip-flop FF is reset by this signal.

When the flip-flop FF is reset, the second comparator 6
0 compares the frame number B stored in the register 24 with the counted value of the counting circuit 26, and when the two do not match, outputs the film drive signal FD from the terminal. Counting circuit 2
6 is a count value C corresponding to the frame number of the frame mark currently detected by the frame mark detector 9. The second comparator 50 is B-C! : Calculates X, outputs a film drive signal FD according to the sign of the value of . That is, the film is fed in the direction in which the mark attached to the frame of the desired frame number B is detected by the mark detector 9. Then, when the frame mark detector 9 detects the frame mark of frame number B of desired information, the count value of the counting circuit 26 becomes B, and the second comparator 6
A film stop signal F8, a copy signal PS, and a set signal BT are output from the terminal C of 0.

The motor is stopped by the film stop signal FB, and the film is stopped. At this time, the frame with the desired frame number B is placed at the copying position (mark detection position) K. On the other hand, set signal B
7 lip-flop PIP is set by T. After the film has stopped, the printer drive unit 56 is activated by the copy signal P8, and the information of the frame with frame number B is copied by the printer. After the copy path r, a copy end signal pg of H is output from the terminal P of the printer drive section 56.

When the flip-flop FF is set, the third comparator 51
compares the frame number A stored in the second register 25 with the count value of the counter circuit 26 (currently rBJ), and outputs a signal σAG from the terminal d when the two do not match.

When the printer drive unit 56 outputs the copy end signal PK, the AND gate ANDI opens and outputs the H winding signal yw, and this signal causes the film drive unit 35 to perform rewinding to drive the film winding shaft in the cartridge 1. The motor is driven to feed the film in the rewinding direction. When the frame mark detector 9 detects the frame mark of frame 1tB-1 while rewinding the film, the differentiation circuit 64 outputs an H signal,
As a result, the AND gate AND2 opens and outputs the H film stop signal FB and the copy signal 2 days. The υ rewind motor is stopped by the film stop signal FB, and the film is stopped. After the film has stopped, the printer drive unit 56 is activated again by the copy signal PSK, and the information of the frame with frame number B-1 is copied. After copying is completed, the printer drive unit 6
When the copy end signal PK is output from 6, AND GO) A
The NDI opens and outputs a rewinding signal RW, which causes the film to be fed in the rewinding direction again. Thereafter, as described above, when the frame mark detector 9 detects a frame mark, the film is stopped and the frame with this frame mark is copied.

After that, repeat rewinding, stopping, copying, and frame number A.
Copying is performed sequentially up to the frame. When the frame mark detector 9 detects the frame mark with frame number A, the count value of the counting circuit 26 becomes human, and the third comparator 51 outputs a signal AG from the terminal e.
is output, and no signal σAG is output from terminal d.

When the frame number A stored in the second register 25 and the count value of the counting circuit 26 match, the signal UAG is not output from the terminal. Even if the post-copying signal PE is outputted from the terminal P of 56, the AND gate AND1 remains closed, so that no film winding operation is performed and no copying operation is performed thereafter.

As described above, each frame from frame number B to frame number A is sequentially copied in this order, and copies arranged in page order are automatically obtained.

After copying the frame with frame number A, the rewind motor is driven by the signal AG output from the terminal e of the fifth comparator 51 to rewind the entire film into the cartridge 1.

Alternatively, the signal AG outputted from the terminal e may not be used to rewind the film, and the signal may be used to indicate on the display unit that copying of a desired frame group has been completed.

Note that the present invention can also be applied to a case where a blank space between each frame of a recording medium is used as a frame mark instead of a frame mark. It is also possible to use a recording medium having marks other than the frame mark, such as a question mark.

〔effect〕

As described above, according to the present invention, copies arranged in page order can be automatically obtained by simply inputting the first address and the last address of the copy range of desired information. Copying work can be done in a short time.

In addition, since desired information can be automatically copied using only the frame marks attached to each piece of information, there is no need to provide special marks other than frame marks on the recording medium. The recording area can be expanded.
