In FIG. 4, numeral 30 is a controller made of a well-known microcomputer that performs overall sequence control for each component, and stores the control procedure shown in FIG. 8 according to the present invention, for example, in an internal memory (not shown). It is. 31 is a signal processing circuit that performs necessary signal processing such as digitization on the analog output signal of the one-dimensional sensor 9;
is a copy button that instructs to start copying. 33 is the second
A dual mode button 34 instructs to read a dual mode microfilm image in which two images are recorded in a direction perpendicular to the transport direction of the film F as shown in Figure (A), and 34 is shown in Figure 2 (B). This is a dual mode button that instructs to read a dual mode microfilm image in which two images are recorded per frame in the transport direction of the film F as shown.

Further, 35 is a memory for storing various data necessary for the recording operation. 3B is a laser beam printer that reproduces and records frame images of the microfilm F on recording paper in accordance with image signals sent from the controller 30; 37 and 38 are A4 cassettes and A4R cassettes set in this printer 36; The A4 cassette 37 and the A4R cassette 38 each store A4 size recording paper, and the paper is stored in different directions in each cassette. Therefore, by selecting these two cassettes, it is possible to record images on A4 size recording paper that is transported in different directions. 38 is a motor for transporting the microfilm.

Next, an example of the operation of the apparatus of the present invention having the above configuration will be explained with reference to the procedure shown in FIG. Note that S1 to S81B indicate control steps.

FIG. 5(A) shows a microfilm image on the imaging plane on the one-dimensional sensor 9 side. In this figure, it is assumed that one frame of a patent publication searched by the subject mark detector 15 by the subject mark Peng 2 is imaged on the image plane scanned by the one-dimensional sensor 9. In this one frame, two images are photographed and recorded in a direction perpendicular to the transport direction of the microfilm F shown by arrow A in this figure, and when the dual mode button 33 is pressed to ON from the keyboard (not shown). (Sl)
, the controller 30 controls the light receiving element group of the one-dimensional sensor 9 to k
Divide into two groups: −mth and m+l to nth groups. Next, in response to a control signal from the controller 30, the laser beam printer 3B prints an A4 image whose short side is in the longitudinal direction of the drum.
A horizontally long A4R cassette 38 containing recording paper of the same size is selected (S2).

In addition, in the case of normal one-frame one-image, the sub-scanning speed V=(=υA4) is determined according to the drum speed of the laser beam printer 3B and the paper size (A4 size), but as mentioned above, In the case of dual mode, the image is recorded on microfilm F at a magnification of 4 times the normal magnification. At the same time, the controller 30 sets the complementation rate K for complementing the read bits in the main scanning direction to Q (S3).
.

When the operator confirms the content of the image on the screen 20 described above and presses the copy button 32, the controller 30 sets the cassette speed as described above and causes the carriage motor 12 to drive if the dual mode button 33 is ON. The one-dimensional sensor 9 sends a signal to the guide rail 10 described above.
．． Scanning is started to read the image plane along line 11 at a constant speed Vd (S4).

The image signal obtained by scanning the one-dimensional sensor 9 is subjected to analog-to-digital (A/D) conversion by the signal processing circuit 31. Among the converted image signals after A/If conversion, k −
The image signal obtained from the m-th light-receiving element group is complemented by the controller 30 based on the above-described complementation rate &, that is, +1 signal is added to l main scanning light and m- to JN
The image signal line (Video Line) is processed to increase the number of lines by (+1 to m-) and then sent to the laser beam printer 36.
(S5).

The laser beam printer 38 blinks a laser beam based on the image signal sent as described above, and creates a latent image on the drum through an optical system. Thereafter, a reproduced image of the first page (the image of the lower half of frame f) is recorded on A4 size paper using a well-known electrophotographic process.

Next, the one-dimensional sensor 9 returns to the home position R in FIG. 5(A) by driving the motor 12 in reverse according to a command from the controller 30, and starts reading scanning again. This time, the same interpolation and transmission processing as described above is performed based on the image signal obtained from the m+1-nth light receiving element group of the one-dimensional sensor 9, and the laser beam printer 3B prints two sheets on the second paper. Print out (S8). In this way, the reproduced image of the second page is obtained. The position of the film F at this time is shown in FIG. 6(A).

When the image reading scan of the second page (the upper half image in frame f) is completed as described above, the controller 30
The motor 38 of the film conveying means is automatically started in accordance with the command (S7), and the microfilm F moves along the arrow A in FIG. 6(A) until the next frame mark ml is detected by the frame mark detector 14. sent in the direction. When the next frame mark m1 is detected (S8), feeding of the film F is stopped and the next frame f is positioned at the image reading position AA (S8). The position of film F at this time is
). Thereafter, the images of the third and fourth pages are sequentially reproduced on the recording paper by the same sequential operation as described above.
Further, the film F is fed as shown in FIG. 6(C), and the images are sequentially reproduced on the recording paper such as the 5th, 6th, 7th, and 8th pages until the next mark recommendation 2 is detected. (SIO).

As described above, in this embodiment, by turning on the dual mode selection button 33, even if there are two images in one frame of the microfilm F, each image can be separated and the desired frame group can be selected. can be played automatically.

Next, an example of the operation of the apparatus of the present invention when there are two images in one frame along the film transport direction as shown in FIG. 2(B) will be described.

FIG. 5(B) shows an image on the imaging plane of the one-dimensional sensor 9. In this figure, the image forming plane scanned by the one-dimensional sensor 9 has the number 1 of the patent publication searched for by the issue mark 112.
The frames are imaged. FIG. 7(A) shows the entire film position at this time. As shown in this figure, two images are taken in one frame in the transport direction A of the microfilm F, and if the dual mode button 33 in FIG. The laser beam printer 38 selects the A4 cassette 37 containing A4 size recording paper having long sides in the longitudinal direction (Sl 1). Further, in this case, since scaling processing of the read image is not necessary, the sub-scanning speed is set to Vd=υA41 and the complementation rate is set to 1 (S12).

When the operator turns on the copy button 32, if the dual mode button 34 is turned on (913), the gear ridge motor 12 is rotated forward by the controller 30 (
S1B), the one-dimensional sensor 9 is the guide rail 10 described above.
．． The imaging plane of the frame image is read and scanned along the line 11. This reading scan of the one-dimensional sensor 9 is performed by moving the photo-interrupter 21 fixed to the main body of the device to the carriage O of the one-dimensional sensor 9.
It starts in response to an output signal from the photointerrupter 21 that is generated when the light shielding plate 22 provided at A (see FIG. 3) passes. The starting position at this time is the R position in FIG. 5(B).

At this time, the laser beam printer 36 generates a well-known Bn signal every time the laser beam scans the drum in the longitudinal direction. Image reading scanning is performed by the dimensional sensor 9 (S17), and as mentioned above, the speed of the one-dimensional sensor carriage 9A at this time is V (= υA
4) The complementation rate for the output signal of the one-dimensional sensor 9 is =
It is 1.

As shown in FIG. 5 CB), the pox image signal obtained from the n-th light receiving element group of the one-dimensional sensor 9 is sent to the laser printer 38 in exactly the same procedure as in the above case, and the image signal of the first page is is reproduced on the recording paper (S17). The above-mentioned one-dimensional sensor carriage 8A receives the above-mentioned BD multiplied signal A.
When four sizes have been counted, the motor 12 is reversed to return to the home position, and the one-dimensional sensor 9 starts scanning the second page again, but this time the light-shielding plate 22 passes the photo-interrupter 21. After scanning from point R until the BD double signal A4 size is counted, reading scanning by the one-dimensional sensor 9 is started.

This starting point is point S in FIG. 5(B).

The image is read and scanned by the one-dimensional sensor 9 until the BD double signal is counted by A4 size, and based on the reading signal of the sensor 9, the frame image of the microfilm F is reproduced and recorded on the recording paper by the printer 3B ( S1B).

When this second page reading scan is completed, the film transport motor 39 rotates forward (S7), and the next frame f is positioned at the image reading position PP (S8). The state at this time is shown in FIG. 7(B). Thereafter, the images of the 3rd and 4th pages, and then the 5th and 6th pages as shown in FIG. 7(C), are reproduced by the same sequential operation until the next mark m2 is detected on the recording paper. Record (StO).

In addition, both dual mode buttons 33 and 34 are turned on.
When the copy button 32 is pressed without any input, the controller 30 regards each frame as a microfilm with one image and performs frame image reproduction processing (S14, 515).
). This operation is the same as the conventional one, so a detailed explanation will be omitted.

In this embodiment explained above, ■ the number of light-receiving element groups, ■ the BD signal counting method, the number of counts (varies depending on the position of the photointerrupter), ■ the speed determination sequence of the one-dimensional sensor, and ■ the complementation rate. Of course, the present invention is not limited to the calculation method, (1) the output page order of reproduced images, (2) the configuration of the instruction means, etc.

Furthermore, in this embodiment, one frame is scanned and read twice, but it is also possible to separate and record two images by one reading. That is, if there are two laser beam printers, even in the case of Is5 (A), two separated images can be printed in one scan, and even with one laser beam printer, the information of one image can be printed in the memory 35. After storing and reproducing the other image, the image information in the memory 35 can also be printed and reproduced.

In addition, the recording means for recording the read information is not limited to the laser beam printer as in this embodiment, but also various printers such as inkjet printers and thermal printers, as well as optical disk devices, magnetic disk devices, magnetic tape devices, and boards. It is clear that various memory devices such as memories are also applicable. In this embodiment, reading of microfilm was explained as an example, but the present invention is not limited to this, and can be applied to reading of ordinary 35-inch film and the like.

〔Effect of the invention〕

As explained above, according to the present invention, when there are multiple images in one frame of film, each image in one frame is read or recorded separately, and then the next frame to be read is read. Since the images are conveyed to the image reading position, the images of the film frame group specified by the operator can be automatically separated and continuously recorded, thereby reducing the burden on the operator.
