Description

[Detailed description of the invention] The purpose of this study is to improve image recording and reproducing devices.

Conventionally, when inputting and outputting image information to a recording medium, it is necessary to move a head to a desired position on the recording medium, and this movement is performed once for each document. Now, let's say that one copy of a manuscript consists of 10 pages.Input one copy of the manuscript, record its image information, play it multiple times, and output it to a printer to output multiple copy prints. In this case, the number of head movements during output is twice as many as the number of copies than during input.For this reason, it is necessary to double-sided copy the image information from a high-density recording medium in a different order than the original order input. When playing back, moving the head becomes complicated and takes a long time.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image information recording and reproducing apparatus that can eliminate the above-mentioned problems and shorten the time required for head movement during double-sided copying.

In order to achieve this object, the present invention provides (1) an even page area for recording even pages of input image information on a recording medium;
The head f is divided into an odd-numbered page area where odd-numbered pages are recorded, and by inputting the image information of the even-numbered pages, addresses belonging to the even-numbered page area are sequentially recorded. ``, by providing an address instruction means for instructing the moving means, complex head movement is performed only at the time of input, and reproduction is possible by simply moving the head in one direction at the time of output. do.

Hereinafter, the present invention will be explained in detail based on illustrated embodiments.

FIG. 1 is a block diagram of an image information recording and reproducing apparatus exclusively for double-sided copying, which is an embodiment of the present invention. The number of copies selection means 11 is for selecting the number of output copies N, and the input means 12 is for selecting the number of output copies N.
The output means 13 receives image information obtained by converting the original into electrical signals from a reader, the output means 13 outputs the image information to a printer, and the recording medium 14 records one page of image information at one address. The input image information is divided into an even day area 15 for recording even pages and an odd page area 16 for recording odd pages.

The address indicating means 17 indicates the addresses belonging to the respective areas to the head moving means 18 by inputting image information of odd or even pages, and 19 is a head.

FIG. 2 shows a flowchart of the entire system in which a reader and a printer are connected to the image information recording/reproducing apparatus shown in FIG. 1, which is an embodiment of the present invention. Step 101
Now, it is checked whether the number of output copies N has been selected by the number of copies selection means 11. In step 102, the head 19 is moved according to the instructions from the address indicating means 17. In step 103, one page of image information is input and recorded in either the even page area 15 or the odd page area 16 on the recording medium 14. In step 104, once all pages have been input, the process moves to playback output. In step 105, head 1
9 are moved on the recording medium 14 in the order of output. In step 106, one page of image information is read out and reproduced and printed on the recording medium 14. Step 107
Now, when printing of one copy is completed, printing returns again from page 1.

In step 108, the process stops after printing the number of output copies N.

Figures 3a and 3c show the operation of the head 19 during recording and reproduction of double-sided copying. Figure 3a & the cross section of the main disk-shaped recording medium 14 and the head 19 are not shown. 14 is a disk-shaped recording 20 is the center of the recording medium 14, 21 is a horn position, and the recording medium 14 is divided into an even page area 15 and an odd page area 16. 22 is a rail for moving the head 19. Therefore, in order to record 101 minutes of image information on the recording medium 14, there are
Address 00 is determined. Addresses 1 to 5 are located in the even white area 15 of the recording medium 14, and addresses 6 to 10 are located in the odd numbered page area 16, and are continuous. Image information of each member is stored on the recording medium 14
M) The head 19 starts from the inner head of each address, moves outward, and records in a spiral shape on the recording medium 14.

Next, 1 [11 works] will be explained with reference to Fig. 2.

The third step tb shows the movement of the head 19 during double-sided copying (step 101 in FIG. 2). Here, it is assumed that there is one original document consisting of seven sheets A, B, C, D, . . . , and that they are input in this order. First, immediately before recording the first document A, the head 19 moves from the home position 21 to the beginning of address 10 in the odd-numbered page area 16 (step 102 in FIG. 2). At this time, the head 19 is moved by using a DC motor (not shown), roughly positioning with a potentiometer/q meter, and then determining the exact position while watching the signal or counting the number of tracks. There are ways to move it to. Furthermore, positioning may be performed using a pulse motor.

A black circle indicates the beginning of the image information of each document, the head 19 moves in the direction of the arrow, and a white circle indicates the end of the image information. On the recording medium 14, there is an address, a signal indicating that it is the start of one page of image information, and a signal for recording the document 13 on the back page when recording is completed at the end of one page of image information. , the head 19 moves to the beginning of address 5 in the number-of-output-page area 15 and records document B. Next, the original C is recorded at address 9, one position inside of original A, the original is recorded at address 4, one position inside of original B, and so on until the original G is recorded. Now, if the input ends t7 in the odd page area 16 (step 104 in FIG.
), the original has an odd number of pages. If the input ends up to the original F, the head 19 ends in the even-numbered page area 15, and the number of originals is an even number.

Figure 3 shows the movement of the head 19 during reproduction 2. The head 19 first moves to the beginning of address 3 of the even page area 15, reads from there to address 11 (primary 5), and reproduces and prints. After the originals F, D, and H are reproduced and output in order, while the head 19 moves to the beginning of address 7 of the odd-numbered page area 16, the work of returning the recorded paper to the paper feed section for double-sided copying is performed. When the number of originals is an odd number, original G is reproduced and printed on unrecorded paper, then original E is placed on the back of original F, original C is placed on the nose of the original holder, etc., and finally the original is printed. Then, the original A is reproduced and printed on MI2 f* paper, and the process ends.

Also, at this time, if the number of originals is an even number, there is no need to print odd-numbered pages on unrecorded paper, and after original B, original F is printed.
The original E is reproduced and printed on the back side of the original, and the printing is repeated in the order of the original C1 and the original A.

In this manner, during reproduction, the head 19 is moved as described above, and the required number of output copies can be reproduced and printed.

In this embodiment, recording is performed by moving the head 19 from the inside to the outside of the recording medium 14, but conversely, the head 19 is moved from the outside to the inside! A similar effect can be obtained by recording 'J%.

Furthermore, the home position 21 may coincide with the innermost part of the even-numbered page area 15, or may be located at the center of each recording area.

The recording medium 14 may be any of the above-mentioned disks (for example, magnetic disks, optical disks, magneto-optical disks), chips, drums, etc., as long as they can perform recording and reproduction.

As explained above, according to the present invention, the recording medium "2" has an even page area for recording even pages of input image information;
The odd page area is divided into an odd page area where odd pages are recorded, and the address to be sequentially transferred to the even page area by inputting the image information of the even page, and the address to be sequentially transferred to the page area by inputting the image information of the odd page, By providing an address indicating means for instructing each head moving means, complex head movement is performed only during input, and reproduction is possible by simply moving the head in one direction across the tsubo during output, making double-sided copying possible at one time. The time required for head movement + Q can be shortened.
