Abstract

PURPOSE:To divide a record region of a reversible record medium to record information on the record medium in one region while erasing the record on the record medium in the other regions. CONSTITUTION:An auxiliary magnet pole 19 is disposed at the opposite side to a disk 23 irradiated by a record beam to record information on the outer peripheral portion of the disk 23. The recorded picture information is reproduced and printed out by a printer. At the same time as this recording, an array of record bits on the inner peripheral portion of the disk 23 is erased. Thereafter, an auxiliary erasing magnetic pole 19 is again rotated to irradiate a light beam spot on the inner peripheral portion of the disk for recording while the array of record bits on the outer peripheral portion of the disk 23 is erased. Similarly, information recorded on the inner peripheral portion of the disk 23 is reproduced and printed out by the printer 4 to produce a required number of prints.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing method and apparatus for storing information in a -H memory and reading and reproducing the information from the reversible memory in accordance with a processing command.

2. Description of the Related Art Conventionally, in copying machines and the like, sorters have been used as devices for collating copies. For example, when making multiple copies of a multi-page original, the sorter reads the original and outputs one image for each page the same number of times as the number of copies, and mechanically transfers the resulting copies to a tray with the same number of pins as the number of copies. They were to be sorted and stacked in page order. However, since the number of bins in such a sorter is limited, the number of bins is limited, so the number of bins in this type of sorter is limited.
There were problems in that the number of sheets to be collected was limited to about 50 copies, and the number of sheets per bin was limited to 20 to 40 sheets.

Therefore, an image information processing method and apparatus that solve the above-mentioned sorter problem have been proposed in Japanese Patent Application Laid-Open No. 140542/1983. In this method, for example, the image information of a document is converted into electrical signals by COD, read, stored in a memory, and the image information is read out from the memory according to processing instructions. If y copies of the original of X pages are required, the entire manuscript is read sequentially and the image information of X pages (for example, T1・'J-'! + ”' + TX-1+
TX) in memory and 7 in the desired page order.
times (for example, [T,,T,,...

Tx)l'['I'l + TI! ”' ＋
'lX:]! + ”' CTI + T2 +
. According to this method, it is possible to obtain a large number of copies of images in a short time using a compact device. 1 The memory used in the above method is a disk-shaped reversible memory, and since it can be used repeatedly every time information is processed, it has an erase function to erase the stored information after use. There is.

However, in conventional information processing methods and devices, the deletion of this information is instructed after the reproduction process is completed.
In addition to the considerable time loss, there was also the possibility of forgetting to delete the data.

In view of the above points, the present invention has been made to improve the above drawbacks, and it divides the recording area of a reversible recording medium,
It is an object of the present invention to provide an information processing method and apparatus for recording on a recording medium in one area and simultaneously erasing recording on a recording medium in another area.

Hereinafter, the information processing method and apparatus according to the present invention will be explained in detail with reference to the drawings.

1 to 6 show an embodiment of the information processing method and apparatus according to the present invention.

In the reading device, a document is placed on a document mounting table 2, and the document is optically scanned while being illuminated with a fluorescent light or the like, and the image information is electrically transmitted to a solid-state image sensor (such as a CCD) 3 via an optical system. This is a device that converts and reads signals. If the printer is a laser beam printer, for example, a light beam modulated based on an image information signal from the document reading device 1 or the magneto-optical disk memory device 5 is imaged and scanned on the photoreceptor, thereby producing a known electrophotographic image. A copy image is obtained in the process.

5 is a magneto-optical disk memory device;
It is possible to record the input signal from the computer and play it back. These original reading device 1, splitter 4, and magneto-optical disk memory device 5 are each linked by a connecting means 6.7.8 such as a coaxial cable or an optical fiber, and receive and transmit signals.

Further, 24 is a condenser lens, 15 is an analyzer used only when reproducing information, 16 is a light receiving element, and 17 is a signal processing circuit.

In addition, when erasing a record, all focusing is done, and when playing back, Kid
Focusing and tracking are performed, and these methods may be, for example, a known astigmatism method or a wobbling method (however, when wobbling, a galvanometer mirror is placed on the optical path), so a detailed explanation will be omitted. Note that 9 is a recording/reproducing optical system consisting of the above-mentioned components.

, splitter 4, and magneto-optical disk memory device 5.

Note that the operation unit 30 and the sequence controller 29 are actually incorporated into the splitter 4. Also, depending on the initial setting conditions, the sequence controller 29 controls the motor drive circuit 2.
8, the motor 20 is rotated in the forward or reverse direction to bring the erase auxiliary magnetic pole shown in FIG. 4 into either state. In addition,
A sequence controller 2911 is configured to input signals from the microswitches 27a and 27b shown in FIG.
-r, the motor 20 is configured to be stopped by a future signal.

FIG. 6 is a flowchart for explaining the method of the information processing apparatus according to the present invention.

Next, an example of the operation of the information processing apparatus according to the present invention and the image information processing method of the present invention will be explained with reference to FIGS. 1 to 6. First, in step 1, physical conditions such as copy density, record information section erase button, number of pages to be copied, etc. are set in the printer 4 via the operation section 30 and the sequence controller 29.

Next, in step 2, the number of copies is given to the sequence controller 29 to control the printer 4. In this example,
This input is the disk 2 of the magneto-optical disk memory device 5.
It also serves as a judgment as to whether or not to use the recorded inner circumference or outer circumference in Step 3. If the number of copies is not input, the document is scanned by the document reading device 1 in Step 3 by pressing the Brit button on the operation section 30. , the read image information signal is directly received by the printer 4, and a copy is output in real time.

If the number of copies is input from the operation unit 30 to the sequence controller 29, step 4 is skipped. The records on the disk 23 have already been erased and are now in a writable state, and when the positional relationship between the disk 23 and the erasing auxiliary magnetic pole 19 is as shown in FIG. In order to erase the recording on the circumference and record image information on the outer circumference of the disk 23 at the same time, the sequence controller 29 rotates the motor 20 via the motor drive circuit 28, as shown in FIG. 4(a). Rotate the shaft 19'bi in the direction of arrow C. Due to this rotation, the permanent magnet 19b presses the terminal magnet of the microswitch 27b to turn on the switch, so that the motor 20, that is, the erasing auxiliary magnetic pole 19, is rotated until the sequence controller 29 inputs a subsequent signal.

At the time when the ON signal from the microswitch 27b is input, the sequence controller 29 stops the rotation of the motor 20 and puts the erase auxiliary magnetic pole 19 in the state shown in FIG. 4(b) and FIG. 2. That is, the permanent magnet 19a approaches the disk 23, and the permanent magnet 19b moves away from the disk 23. The direction of the relatively strong magnetic field of the permanent magnet 19a toward the disk 23 is opposite to the direction of magnetization of the recording bits on the inner circumference of the disk 23, and the direction of the relatively weak magnetic field of the permanent magnet 19b toward the disk 23 is opposite to the direction of magnetization of the recording bits on the inner circumference of the disk 23. The direction is opposite to the direction of magnetization of the erased portion of the outer circumference of the disk 23. That is, the directions of the magnetic fields of the permanent magnets 19a and 19b are opposite to each other. As a result, the permanent magnet 19a acts as an erasing magnetic pole, and the permanent magnet 19b acts as an auxiliary magnetic pole for recording. On the contrary, when you want to record on the inner circumference of the disk 23 and erase the record on the outer circumference, the motor 20 rotates the rotating shaft 19'bf: in the direction of the arrow in FIG. When the erasing auxiliary magnetic pole 19 is rotated to the position where the magnet 19a presses the terminal of the microswitch 27a and then stopped, it becomes as shown in FIG. Since it moves away from 23, permanent magnet 1
9b acts as an erasing magnetic pole and as an auxiliary magnetic pole for recording on the permanent magnet 19aiJ.

In step 5, the output page order is specified to the printer 4 via the operation unit 30 and the sequence controller 29 (for example, output is in the reverse order of input or every other page, etc.), and in step 6, the document reading device 1 specifies the output page order. The original is read, and this read multi-signal is input to the magneto-optical disk memory device 5 to record and store image information on the outer (or inner) portion of the disk. The records on the periphery (or outer periphery) are erased.

This recording erasure will be explained in more detail with reference to FIG. In this case, for example, we will take a case where data is recorded on the outer circumference of the disk and at the same time the recording on the inner circumference is erased.

It is assumed that the erasing auxiliary magnetic pole 19 is set at the position shown in FIG. 2 as described above.

In FIG. 2, the disk 23 is, for example, an evaglass disk (
A magnetic film having a composition such as G), Tb, F'e, etc. is deposited by sputtering or the like. When erasing a record, the analyzer 15 is moved out of the optical path by means not shown, and a light beam modulated based on the information emitted from the laser light source 10 according to the reading information from the reading device 1 shown in FIG. The collimator lens 11 converts the light into parallel light, which passes through the polarizer 14 and beam splitter 12 to the condensing lens 13.
A beam spot having a diameter of about 1 μm is focused on the surface of a disk 230 which is being rotated by a motor 18 around a rotation shaft 25 as a center of rotation. Here, the magnetic film of the disk 23 is magnetized in advance with its orientation aligned in the vertical direction, and the direction of magnetization is reversed by the irradiation of the light beam and the magnetic field of the permanent magnet 19b, and image information is transmitted as shown in FIG. This bit 26 is recorded on the outer periphery of the disk 23. At the same time, the recorded bit string recorded on the inner circumference of the disk 23 is erased by the strong magnetic field of the permanent magnet 19a placed on the inner circumference side of the disk 23.

On the other hand, during reproduction, the analyzer 15 is placed in the optical path, and the laser light source 10 emits a light beam of constant intensity, which is linearly polarized by the polarizer 14 and applied to the bit string formed on the outer periphery of the disk 23. irradiate. Then, the reflected light from the disk 23 is rotated according to the recorded information by the magnetic Kerr effect, and the total beam splitter 12. The light is directed to the light receiving element 16 through the condensing lens 24 and the analyzer 15, and the signal is detected and the recorded image information is reproduced by the signal processing circuit 17. Note that during recording, shift focusing is performed by means not shown, and during reproduction, shift focusing and tracking are performed by means not shown.

Also, during recording and reproduction, the optical recording/reproducing system 9 is moved in the direction of the arrow shown in the figure by means not shown.

In the above disk, the interval between bit rows (track pitch) is 2 μm, and the diameter of the disk is 2 μm.
If the recording area is up to 00 darkness, the amount of information of about 20 bits can be recorded in the whole area, but since only the outer periphery of the disk is recorded, the amount of information of about IGbit can be recorded, and the image information of A4 size can be recorded in l 5 pet. Approximately 60 discs can be stored (however, even if you record on the inner circumference of the disc, the same < 1
6 pels can store 60 A4 size sheets). This recorded image information can be arbitrarily searched within the area of the disc 23 divided into two by moving the optical recording/reproducing optical system 9 as shown in FIG. 2 relative to the disc in the radial direction of the disc (ranodum access). After the image information is recorded on the outer circumference of the disk 23 as described above, the image information is stored based on the above conditions in step 6, and then the process proceeds to step 7, in which the image information is stored in the magneto-optical disk memory device 5.
The images are reproduced in order as shown in the output of the required number of copies, and the reproduced signal is sent to the splitter 4, which outputs the required number of copies.

As described above, when recording signals on a magneto-optical medium, the present invention arranges an auxiliary magnetic pole on the opposite side of the disk to which the recording beam is irradiated, and records on that part, in order to improve the recording efficiency. When erasing the recorded signal, the auxiliary magnetic pole and the other magnetic poles are placed close to each other, so that the recording signal is recorded on the outer circumference at the same time as all the recorded signals are recorded, and this recorded image information is reproduced and blit-out by the printer 4. During this recording, the recorded bit string on the inner circumference of the disk 23 was erased at the same time, but when step 4 was reached again, the erasing auxiliary magnetic pole 19 was rotated as described above to bring it into the state as shown in Fig. 4. , it is possible to record by irradiating the light beam spot onto the inner circumference of the disk and at the same time erase the recorded bit string on the outer circumference of the disk 23.Similarly, what was recorded on the inner circumference of the disk 23 can be reproduced and printed on the printer. You can print out the required number of copies in 4.

In the present invention, the image information memory device is not limited to a magneto-optical device, but any device that uses a reversible recording medium may be used. For example, a reversible recording medium that changes from unrecorded to recorded due to the phase transition state of an amorphous two-crystal such as SeS chalcogenide glass may be used. In this case as well, the disk-shaped recording medium using this material may be divided into two areas, one area may be recorded with a beam such as an optical Ar laser, and at the same time, the other area may be erased by irradiating it with an infrared lamp. . In other words, separate infrared lamps are provided over the two areas, and an infrared lamp that irradiates an area other than the area selected for recording is selected, and this infrared lamp is used during recording. The recording in one of the two divided areas may be erased at the same time as the above area is irradiated and recorded.

Furthermore, in the present invention, the information to be recorded and reproduced is not limited to image information as in the embodiments, but may be information such as the output of a computer, for example.

As described above, in the information processing method and apparatus according to the present invention, when dealing with image information, for example, when a certain number of copies is required, the printer prints it out in real time, and when there is a plurality of copies, - The image information is memorized and printed out, but at this time, unnecessary image information that was previously memorized is erased at the same time as it is memorized, so next time, this erased portion is used, resulting in extremely fast information processing. became possible.
