[Conventional technology]

Conventionally, devices have been known that can record information such as documents generated in large quantities at high density on microfilm, read the images on the microfilm as needed, and print them out in a predetermined size. It is being For example, as shown in Figure 2, the particularly high-density microfilm used in this type of device can be either vertically elongated (half size: Figure 2) or horizontally (full size: Figure 2). B
))).

[Problem that the invention seeks to solve]

By the way, conventional devices have a reading range that can read a full-size image in one scan, but when reading a half-size image, they scan one frame at a time, transport the film, and then read the next frame image. I was reading it. Therefore, when reading a half-size image, unlike the case of a full-size image, it is necessary to accurately stop the film at a predetermined position with a short film feed amount, which complicates the film feeding and stopping control force. When reading multiple frames of images, there is a problem in that a large amount of time is used for transporting the film, and the image reading efficiency is reduced.

Therefore, in view of the above-mentioned problems, an object of the present invention is to read two successive half-size images at a reading position for a film with consecutive half-size frames, and to scan the reading scanning position after reading these two half-size images. By transporting the film in the same way as full-size frame transport, in which two other frames are transported and then read two more frames, transport time is shortened and image reading efficiency is improved. It's about letting people know.

[Means for solving problems]

In order to achieve such an object, the present invention provides an image reading means for reading and scanning image information recorded on a film, and an image reading means for selectively extracting the image information specified by inputting an instruction from the film. An image retrieval means for transporting and stopping at a reading scanning position.

The image reading means causes the image information reading scanning to be performed for each frame of the film in the reading scanning area, and the image searching means is configured to convey the next image to the reading scanning position after the reading scanning of the designated image information is completed. The invention is characterized by comprising a control means for operating the apparatus.

[For production]

Since the present invention has the above-described configuration, when reading and reproducing a film in which two consecutive images are provided in one screen of the film, two consecutive frames of images in the reading scanning area are continuously read and reproduced. (hereinafter referred to as continuous page copying).

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example of the basic configuration of the apparatus of this embodiment.

As shown in this figure, the image information in the specified film is selectively extracted by the image search means, and the image information is conveyed and stopped at the reading scanning position detected by the position detection means C. Reading) If there are, for example, two frames of images on the film screen at the scanning position, by pressing the continuous shooting button d, the image reading means a is caused to scan each frame via the control means e. The image information is output respectively. After this reading is completed, the control means operates the image retrieval means to transport the next read image on the film to the reading 9 scanning position, and again 2 frames lI! ii) Repeat the image capturing operation. However, this is not the case when there is no need to read two frames.

Although the present invention can be applied to conventional analog league printers that process microfilm images in an analog manner, there are problems with ease of changing magnification, diversity and versatility of recording materials, etc. For this reason, the present invention will be explained by taking as an example an electric image reading means using an image sensor such as a COD (charge coupled device) suitable for digitally reading images. In addition, as recording materials,
Although various materials such as paper, magnetic chips, magnetic disks, optical disks, and hard disk memories are applicable, the following embodiments of the present invention will be explained using paper as an example.

FIG. 3 shows an example of the internal configuration of a microfilm image reading device of the present invention that photoelectrically reads images on microfilm. In this figure, a strip-shaped microfilm F is housed in a cartridge 1 and is fed out from the cartridge 1 by a capstan roller 2 and a pinch roller 3, and a film guide member (not shown) is moved to an idler roller 4.5. The film is sent to a take-up reel 6, and wound onto the take-up reel 6 driven by a motor (not shown).

The microfilm F records, for example, a frame f recorded in the page order of a large number of patent publications, a frame mark m1 recorded at the bottom of each frame as shown in Figure 2, and information on the first page of each patent publication. It has an issue mark m2 recorded on the top side of the frame. The microfilm F is irradiated at a predetermined position by a run f7, and the information of the irradiated frames is transferred to a one-dimensional photoelectric conversion means (such as a CCD (charge-coupled device)) by a lens 8.
An image is formed on the scanning plane of 9 (hereinafter referred to as a one-dimensional sensor).

The one-dimensional sensor 9 is magnetically main-scanned and is driven and scanned by the carriage motor 12 via the wire 13 along the guide rails 10.11 provided on the main body, so that it is positioned at a predetermined position and read. The information of the frame projected within the area 16 is read.

5, the mark recording section of the microfilm F passes between the frame mark detector 14 and the frame mark detector 1.
The light incident on the detector 5 is interrupted by the mark ml r m2, and a mark signal is output from each detector.

A controller shown in FIG. 4, which will be described later, counts the number of mark signals output when the mark mark detector 15 detects the mark m2, and depending on the count value, stops feeding the υ film and moves the microfilm F as described above. to stop at a predetermined lighting position.

The operator monitors the image projected onto an optical screen (not shown) via a monitoring optical system (not shown), confirms that it is the desired patent publication, and presses a copy button (not shown). As a result, a reading operation using the one-dimensional sensor 9 described above starts.

Then, using the read output of this sensor 9, a copy image is obtained on recording paper by a recording means to be described later.

Further, numeral 21 is a photo ink club which detects the home position of the one-dimensional sensor 9, and outputs a position signal when the emitted light is blocked by a light-shielding plate 22 fixed to the one-dimensional sensor 9.

FIG. 4 shows an example of the configuration of the control system of the apparatus of the present invention shown in FIG. In FIG. 4, numeral 30 is a controller made of a well-known microcomputer that performs overall sequence control for each component, and stores control procedures and the like to be described later according to the present invention, for example, in an internal memory (not shown). be.

Further, 35 is a memory for storing various data necessary for the recording operation. 36 is a radar beam printer that reproduces and records frame images of microfilm F on recording paper in accordance with image signals sent from the controller 30; 37 and 38 are A4 cassettes and A3 cassettes that are sected to this printer 36; The A4 cassette stores paper whose length is perpendicular to the paper transport direction, and the A3 cassette stores paper whose length runs in the paper transport direction. Therefore, by selecting these two cassettes, half-size and full-size images can be recorded on recording paper. In other words, a half-size image is A4. Full size images are each recorded in A3. 3
9 is a motor for transporting the microfilm.

Next, the operation of the apparatus of the present invention having the above configuration will be explained with reference to FIG.

FIG. 5(A) shows an image on the imaging plane on the one-dimensional sensor 9 side when a half-size film is used. When reading an image of such a half-size film in which two frames of the patent publication are formed, the base photography mode button 33 is turned on. Note that the symbol T indicates the missing edge of the reading frame of a full size (A3, A4R, 84, etc.). After confirming on the optical screen that these two frame images are the desired images, the operator presses the copy bit/32 button and inputs an ON signal to the controller 3°. When an ON signal is input to the controller 30 from the copy button 32, the calitz motor 12 is rotated in the normal direction, and the one-dimensional sensor 9 is moved to the above-mentioned guide rail 10.11.
The imaging plane of the frame image is read and scanned along the . This reading scan of the one-dimensional sensor 9 occurs when the light-shielding plate 22 provided on the carrier horn 9A (see FIG. 3) of the one-dimensional cell 9 passes the photointerrupter 21 fixed to the main body of the device. It starts in response to an output signal from the photointerrupter 21. The starting position at this time is the R position in FIG. 5(A). Also, at this time, a well-known BD double signal is generated from the Redebeam printer 36 every time the Redebeam scans the drum in the longitudinal direction. sensor 9
Performs image reading and scanning.

As shown in FIG. 5 (8), the image signals obtained from the k-nth light receiving element group of the one-dimensional sensor 9 are sent to the laser beam printer 36, and the IK-th image is reproduced on the recording paper. When the above-mentioned one-dimensional sensor caliper 9A has been counted by the above-mentioned BD double signal A4 size, the motor 12 is reversed and returns to the home position.
The one-dimensional sensor 9 starts scanning the second page again, but this time, from the point R where the light shielding plate 22 passes the photointerrupter 21, the BD double signal next lil! After scanning is performed until j image tip positions (It-P) are counted, reading scanning by the one-dimensional sensor 9 is started.

This starting point is point P in FIG. 5(8).

The image is read and scanned by the one-dimensional sensor 9 until the BD double signal is counted by the A4 size, and based on the read signal from the sensor 9, the frame image of the microfilm F is reproduced and recorded on a small recording paper by the printer 36. . When the reading and scanning of this second page is completed, the film transport motor 39
The frame f, which is two frames ahead by skipping one frame, is positioned at the image reading position R by normal rotation. The state at this time is shown in Fig. 5 (B). After that, by the same sequence operation, the next mark m2 is detected on the recording paper on the 3.4th page, and then on the 5.6th-9th page. It will be played and recorded until it is played.

Note that when the page continuous shooting mode button 33 is not turned on and the copy button 32 is pressed, the controller 30 reads one frame, conveys the next frame, and sequentially reproduces the frame images.

This operation is the same as the conventional one, so a detailed explanation will be omitted.

In this embodiment described above, ■ BD double signal counting method, count number (varies depending on the position of the photo interrupter), ■ output page order of reproduced images, ■ configuration of instruction means, etc. do not limit the present invention. Of course not.

Furthermore, in this embodiment, one frame is scanned and read twice, but it is also possible to separate and record two images in one reading. In other words, after reading the first frame image, 1
It is also possible to scan between the trailing edge of the frame 8 and the leading edge P of the second frame while detecting it using a BD count, etc., and read and reproduce the second frame from the position of P. In this case, the time can be further shortened. Of course, it is also possible to store the second frame in the memory 35, reproduce the other image, and then print and reproduce the image in the memory 35.

In addition, the reading start position of the -11th frame and the reading start position of the 2nd frame are set, for example, on the optical monitor screen.
A reading position indicating means connected to the linear potentiometer may be provided, and the instruction may be made based on a signal from the IJ near potentiometer that is output corresponding to the position indicated by the reading position indicating means.

Furthermore, the recording means for recording the read information is not limited to the radar beam printer as in this embodiment, but also various types of printers such as inkjet printers and thermal printers, as well as optical disk devices, magnetic disk devices, and magnetic tapes. It is clear that various memory devices are also applicable, such as device and gate memories. In addition, although this example has been explained using the example of removing the edges of a microfilm, the present invention is not limited to this.
It is applicable to reading ordinary 351 film and the like.

〔Effect of the invention〕

As explained above, according to the present invention, when reading and reproducing a film in which two images are consecutively provided in one image of the film, two frame images can be generated by one transport. Since each image is read and scanned, the time required for reading and reproducing can be shortened, and the image reading efficiency can be improved.
