Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention detects a mark on an information recording medium such as a microfilm and counts the mark to automatically retrieve desired information in the information recording medium. The present invention relates to an information retrieval device.

(Prior Art) Conventionally, a search device incorporated in a film reader or the like uses a film having a search mark on the side of each frame of the film, optically detects this mark, and counts it. As a result, the desired frame in the film is automatically searched.

The above search device illuminates the mark on the film with a lamp,
When the film is transferred, the change in the light blocked by the mark is detected by the mark detector, the output signal of the mark detector is counted by the counter, and the count content of the counter and the desired input from the keyboard or the like are input. The comparison circuit compares the frame number of the image frame, and when the two match, the comparison circuit issues a stop signal to the drive control circuit to stop the drive system that transfers the film and project the desired frame on the screen. It is made to stand still at a predetermined position.

By the way, when it is desired to obtain the print images of a plurality of frames in the retrieval device, the addresses of the plurality of frames are previously input to the memory and printing is sequentially performed after the input.

(Problems to be Solved by the Invention) However, in such a conventional example, addresses of a plurality of image frames to be printed are randomly input, and the image frames are sequentially searched and printed in the input order regardless of the address order. As a result, the film is repeatedly transported in the forward and reverse directions, and there is a problem that it takes time to retrieve and print all desired image frames.

Also, since a series of image frames on the film generally have images recorded in page order, when such a film is used, printing is performed in any order,
There is a problem that the print bites must be realigned in order after printing is completed.

As a means to solve this, it is conceivable to enter the addresses in order so that printing can be done quickly, but this takes time and effort to enter the addresses, and again it takes a long time, and as a result, as a whole. However, there was a problem that the printing time of was long.

Therefore, the present invention has been made to solve the above-mentioned problems of the conventional example, and the purpose thereof is to efficiently print even if the addresses of a plurality of image frames are randomly input. Another object of the present invention is to provide an information retrieving apparatus capable of performing printing in the order of addresses regardless of the order of input.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, while the information recording medium having a large number of images and search information for searching the images is moved, the search information is In an information retrieval apparatus for retrieving a desired image by detection, an input means for inputting each address on an information recording medium of a plurality of images to be printed before retrieval, and a storage means for storing the plurality of input addresses A means for rearranging and reading out a plurality of addresses stored in the storage means in a predetermined address order, an image of each address read out in the predetermined address order is searched in the address order, and the images are searched in the searched order. And means for controlling to print.

(Operation) In the present invention having the above-mentioned configuration, since the reading means reads the addresses of a plurality of images randomly input to the storage means in the order of addresses, only moving the information recording medium in a fixed direction. You can search for the desired image with. Further, the control means is adapted to print the image in the order of the read addresses.

(Example) Below, this invention is demonstrated based on the Example shown in figure. Fifth
The figure shows a film feeding section of a film reader with a search device to which the present invention is applied. In the figure, 1 is a film supply cartridge for storing a microfilm F as an information recording medium in a roll shape, and 2 is a cartridge 1 inside. A capstan roller for sending out the microfilm F, M1 for driving the capstan roller 2, M2 for rewinding the film spool in the cartridge, and SOL1 for supporting the capstan via the support arm 3. Solenoid for contacting the roller 2 with the microfilm F, 4
Is a spring that moves the support arm 3, the plunger 3a, and the capstan roller 2 to separate the capstan roller 2 from the microfilm. SOL2 is a brake solenoid for the film rewinding motor M2. When the brake solenoid SOL2 does not operate, The motor M2 is rotatable, and when the brake solenoid SOL2 is activated (turned on), the braking plate 5 fixed to the motor shaft is attracted to prevent rotation of the motor.

Reference numerals 6 and 7 are film guide rollers, 8 is a take-up reel, M3 is a film take-up motor for rotating the take-up reel 8, and SOL3 is a brake solenoid for the motor M3.

Further, although not shown, a guide plate for guiding the film along the film feeding path between the cartridge 1 and the take-up reel 8 is provided.

14 is a lamp for illuminating the microfilm F, 15 is a condenser lens, 16 is a projection lens for enlarging and projecting the image of the film F illuminated by the lamp 14 onto a screen (not shown), and 17 is each frame of the microfilm F. This is a known mark detector for detecting the counting mark m provided on the side.

The mark detector 17 has a photoelectric conversion element and emits a mark detection signal when the light beam from the lamp 14 is interrupted by the mark m when the film F is transferred. The mark detection signal is a counter of the retrieval device. Counted. Since the details of the search device are publicly known, description thereof will be omitted.

When the frame number A of a desired image frame is input to the input device of the search device, the motor M1 is driven and the solenoid SO
L1 is activated. As a result, the capstan roller 2 comes into contact with the microfilm F coming out of the cartridge 1, and the microfilm F is pulled out from the cartridge 1,
The tip is fed toward the take-up reel 8. When the leading edge of the microfilm approaches the take-up reel 8, the take-up motor M3 is driven, and when the leading edge of the microfilm winds around the take-up reel 8, the motor M1 and the solenoid SOL1 become inoperative. The take-up reel 8 rotates to continue feeding.

The number B of marks m detected by the micro film feeding mark detector 17 is compared with the number A of the frame number input in advance, and if they match, a stop signal is generated to generate a brake solenoid.
SOL3 operates and brakes the take-up shaft 11, and SOL2 also brakes the shaft of the motor M2 to stop the coasting rotation of the sending spool, the film feeding is stopped, and the image of the frame of the desired number A is projected. It is projected on the screen through the lens.

On the other hand, FIG. 3 shows the microfilm F used in this embodiment.
In this microfilm F, the large mark l
The numbers marked with are the batch numbers, those marked with the above-mentioned mark m are the file numbers, and those marked with the small mark n are the page numbers.

FIG. 2 is a block diagram showing the control system of FIG. 5, in which 20 is a microprocessor, and this microprocessor 20 serves as a control means for controlling the address order of a plurality of image frames in a desired order. It is composed of a control unit 21, a memory 22 as a storage unit for storing addresses in the order input from an input device 24 as an input unit such as a keyboard, and a print memory 23. The control unit 21 also has a function as a unit for reading the addresses randomly input from the input device 24 and stored in the memory 22 in the order of addresses. 25 is a display as a display means for displaying the contents of the memory 22, and 26 is a motor drive control circuit for feeding and stopping the film F based on the stored contents of the print memory 23.

In the above configuration, in the present embodiment, the addresses are first stored in the memory 22 in the order of input from the input device 24,
When the input is completed, the print order numbers are assigned in ascending order of the addresses, and when the print execution command of the contents of the memory 22 is received, the print order is searched,
Print.

That is, as shown in the flow chart of FIG. 1, first, in a step, in order to print a plurality of frames on the film F, the addresses of those frames are inputted in advance from the input device 24, and this is stored in the memory 22 at the step. Remember.
Then, when the print execution command is sent in step,
In step, the first reading of the contents of the memory 22 is performed. In the step, it is judged whether or not it is smaller than the next memory content. If it is larger, the memory content is read in the step. If it is smaller, it is judged in the step whether or not it is compared to the end. If not, return to the step again. If the step is compared to the end, write to the print memory 23 in the step, erase the memory in the step, and then judge in the step whether all the memory contents have been compared. In step, the contents of the print memory 23 are printed in order. If the comparison is not completed in step, the process returns to step.

In this way, for example, if the addresses shown in Table 1 are sequentially stored in the memory 22, printing is performed in the print order shown in FIG. 4 (a).

In Table 1 above, the address "1.1.2" is the batch number 1, the file number 1, and the page mark 2.

By the way, although the print order shown in Table 1 is an example of the print order with respect to the memory numbers, the memory numbers may be rearranged in ascending order of addresses as shown in Table 2. Therefore, printing is performed in the order shown in FIG.

However, the address order does not always have to be arranged in ascending order, and it is also possible to arrange in the order in which printing can be performed quickly depending on the status of the address in the film and the current address position. That is, when the middle position of the film F is searched, printing is performed in order from the end of the film F, or in Table 3 and FIG. 4 (c).
After the film F is fed to the end as shown in (4), printing may be performed in the forward direction according to the addresses arranged in descending order.

Further, in this embodiment, when there is a code for designating addresses and the like, and when the arrangement order of the addresses is unknown, the film F is once fed to the end and the address is stored, and based on the stored content, You can also set the order in which you can print quickly.

(Effects of the Invention) The information search apparatus according to the present invention has the above-described configuration and operation, and even if addresses of a plurality of images are randomly input without considering the print order that enables quick printing. Since the reading means reads it in the order of addresses, it is possible to efficiently search for a desired image simply by moving the information recording medium in a fixed direction regardless of the order of input, and it is possible to shorten the search and print time for all desired image frames. . Further, since the control unit prints the image in the order of the read addresses, it is possible to discharge the printed sheets in the order of the addresses, and it is possible to eliminate the need for the ordering after the discharging. Has the effect.
