Abstract

PURPOSE:To relieve the anxiety such as leakage of secret information and to attain sure reproduction/erasure of storage information by easing automatically the information stored already in a memory means according to an erasure command signal transmitted from a picture forming means while new picture information is stored after the end of reproducing processing. CONSTITUTION:When a memory input is finished, the stored picture information is reproduced in order by an optomagnetic disc memory device, the said reproducing signal is fed to a printer 4 and a copy picture is outputted. When all printout is finished, a copy end signal S is fed to the optomagnetic disc memory device 5 from the printer 4 and the information stored on the disc is erased by the optomagnetic disc memory device 5. If a trouble such as paper clog takes place in the printer, no reproduction end signal is generated and it is possible to make re-output after the trouble is restored.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an image information processing device, and more specifically, to an image information processing device.
#Report This invention relates to an image information processing apparatus which temporarily stores the image information in a memory IC, reads out the image information from the memory in accordance with a processing command, and reproduces the information.

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 copying several copies of a multi-page original, the sorter reads each page the same number of times as the number of copies, outputs the image, and stores the resulting copies in a tray with the same number of bins as the number of copies. mechanically sorted into
I had to correct the pages in order. However, since such a sorter has a finite number of bins, it is limited to collating about 10 to 50 copies, even though the device is large, and the number of sheets per bin is also limited to 20 to 40. There was a problem.

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 is converted into an electrical signal by a manuscript COD, etc., and read, the image information is temporarily stored in a memory, and the image information is read out from the memory according to a processing instruction, and reproduction processing such as copying is performed. Brush up on things. Here, if you want X pages of manuscript t-y copy, e(- means read the manuscript sequentially,
III information (for example, T1゜'r, , -・-, Tx-0,
Tx) 'if memory dC a-c, y times in desired page order (e.g. (Tl, rt,...'* 'I
XJI l('1'+, Tx, -, TJt
,...c'f'l,'i't,...TxJ
K) The above-mentioned information ft is read out and copies of y copies in the desired page order are stored. With this method, it is possible to print a large number of copies of images in a short time using a compact device.

The memory used in the above method is a reversible memory, and since it is used repeatedly every time image information is processed, it has a function to erase stored information. The deletion of this image information can be instructed after the playback process is completed and before new image information is stored in the memory, but it would be troublesome to operate the memory each time.

Also, considering the possibility of forgetting to erase the data, it is not desirable from the perspective of maintaining the confidentiality of information. Therefore, it would be good to have a configuration that automatically erases the stored information after the playback process, but
If this process is performed only on the memory side, inconveniences will occur when a problem occurs in an image forming means such as a copying machine. For example, if the memory independently erases stored information when the recycling process has not been completed completely due to a paper jam, etc.
If it becomes necessary to read the manuscript again, and if the manuscript has already been discarded, the worst case scenario is that information will be lost.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image information processing apparatus that can reliably reproduce and erase stored image information with simple operations.

The present invention provides an image information processing device comprising an input means for inputting image information, a memory means for storing the information, and an image forming means for reproducing an image from the stored information. After the information has been reproduced, until new image information is inputted and stored in the memory means, the image information already stored in the memory means is deleted in accordance with an erasure instruction signal sent from the image forming means. The above purpose is achieved by automatically erasing the information.

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

FIG. 1 is a 3-perspective view showing an example of the image information processing apparatus according to the present invention. In FIG. This is a device that optically travels the document while illuminating it with a fluorescent light or the like, and converts image information into an electrical signal using a solid-state image sensor (such as a CCD) 3 and reads the image information. 4 is a printer, for example, in the case of a laser beam printer, a laser beam modulated based on the image information (g) is imaged on a photoreceptor, and a copied image is printed using a known electrophotographic process. Reference numeral 5 denotes a magneto-optical disk memory device that can record human input signals and reproduce them.These document reading device 1, printer 4, and magneto-optical disk memory device 5 are each connected to a coaxial cable. Alternatively, they are linked by a connecting means 6°7.8 such as an original fiber, and signals are exchanged.

The magneto-optical disk memory device 5 will be explained in more detail with reference to FIG. In Figure 2, a disc-shaped recording medium (
(hereinafter referred to as a disk) 9 is a glass disk with Gd
, Tb, Fe, etc., is deposited by sputtering or the like. During recording, the original beam modulated based on the information emitted from the laser light source 10 is made into parallel light by the collimator lens 3, and the polarizer 14
After passing through the beam splitter 12, the beam is focused on the surface of the disk 9 by a condenser lens 13' as a beam spot having a diameter of about 1 μm. Here, the magnetic film of the disk 9 is aligned and magnetized in the perpendicular direction in advance, and the direction of magnetization is reversed by the irradiation of the laser source described in step 111, and the image information is transmitted as shown in bit 18 in FIG. This is something that is recorded on a disc.

On the other hand, during reproduction, a light beam of −2 intensity is emitted from the laser light source IO, the light beam is linearly polarized by the polarizer 7, and the direction of the reflected light from the disk 9 whose polarization plane has been rotated is changed by the beam splitter 12. The signal is guided through the entire analyzer 15 to the light receiving element 16, all signals are detected, and the signal processing circuit 17 outputs tqil.
The recorded image information and sound are played back.

In the above disk, the interval between bit strings (track pitch) is 2 μm, and the diameter of the disk is 100 to 20 μm.
(If the recording area is up to 1 meter, the amount of information of about 2 Q bits can be recorded, and about 125 A4 size image information or 169el can be stored. Arbitrary searches (random access) can be performed by moving such an optical system in the radial direction of the disk relative to the disk.

Further, the above-mentioned recording can be easily erased by applying a strong magnetic field that matches the magnetization direction before recording to the disk.

Next, block (9) of the first embodiment of the image information processing apparatus configured as shown in FIG. 1 will be shown as the fourth factor, and an image information processing method using this apparatus ii will be explained with reference to the flowchart of FIG.

In this embodiment, this input also serves as a judgment as to whether or not the memory is to be used. If there is no number of copies or input, the process moves to step 3, and the reading start signal from the 7° printer 4 is sent by turning the start button 42 ON. At Q, the original is picked up by the original reading device 1, the reading signal R is directly received by the printer 4, and a copy is output in real time.

If the number of copies was entered in step 2, step 4

Further, when all printing is completed, a copy completion signal S is sent from the printer 4 to the magneto-optical disk memory device. In addition, this copy end signal S is used as an indication signal. These jft s & Niu → printout processes are performed by each C of the magneto-optical memory device @ 5 and the printer 4.
The information stored on the disk by the magneto-optical disk memory device 5 in step 7 is then controlled by the PU 32.26 and the memory 31.25. ? r Erase.

Erase recorded information on the disc. During this erasure grace period, the user can check all the copies for mistakes, or check the number of copies and supplement the copies.

In the above embodiment, the internal timer of the CPU was used as the timekeeping means, but an external timer connected to the CPU could also be used.
I won't do anything. Further, this timer may be provided with an erasure delay time setting means so that it can be set to θ[short poem 1-J'e as described in 111. It is also possible to connect a clock to the CPU and automatically erase data at a preset time (for example, midnight every day) instead of at a fixed time after the end of the playback process. Furthermore, in the above-mentioned example, the recorded information was erased immediately after the output path f (when the immediate erase button was ON). Delete recorded information immediately.

Alternatively, J31' may be automatically deleted after a certain period of time.

In the case of this embodiment, if a trouble occurs in the printer such as paper load try=J, the reproduction end signal is not issued, and after the trouble is resolved, it is possible to take measures such as re-outputting and re-printing.

Next, the second
A block diagram of the embodiment is shown in FIG. 6, and an image information processing method using this device will be explained with reference to the flowchart in FIG.

First, in step 1, the copy density f on the operation panel 43 and the foot lever 51 are operated to set initial conditions t such as copy density. This copy! The Ijf setting signal is sent to the original reading device 1 and the printer 4, and in the printer 4, it is sent to the printer 4 via the boat 24 as a No. 18 D signal to the m degree adjustment circuit 57F (L input is broken. The number of copies is input using the capotan 52. In this embodiment, this manual also serves as a judgment as to whether or not the memory is to be used, and if the number of copies is not input, the VC moves to step 3V and presses the start button 44. According to 0NvL, the printer 4 receives the dt capture start signal Q and reads the original with the original reading device @l, and the printer 4 directly receives the reading signal R and outputs a copy in real time.

In step 2, if the number of copies is manually transmitted, the printer 41 sends an erase signal S(P
') is sent to the port (601C) of the magneto-optical disk memory device 5, which activates the erase drive circuit 63 as a signal 8', erasing the information recorded in -j- by the previous use. In other words, when new image information is manually stored in the memory, the memory is refreshed 1 on VC*, 7g, and the maximum storage capacity is 11 (for example, the A4, 16pel).
So 125. (equivalent to lk) is guaranteed to the user.

Next, the process moves to step 5, and the output page order is specified using the output order specification button 53 (for example, the output is in the order of input j#1 or every other page). Next, in step 6, the original is read and the information is stored on the disk. In this step,
In accordance with the start ST from the start button 44, the reading start signal Q is sent from the printer 4 to the boat 67 of the document reading device [l].
sent to.

And CPU69. COD driver circuit 70J while being controlled by 1 in memory 68? and optical system drive path 1 71 to read the original. This read signal R is sent to the boat 60 of the magneto-optical disk memory device 5,
The signal R' is input to the laser JR modulation circuit 64, and the laser beam modulated as described above is irradiated onto the disk to store image information.

When the memory input is completed, in step 6, the stored images are sequentially reproduced in the magneto-optical disk memory device based on the above-mentioned conditions, and the reproduction signal is sent to the printer 4 to output an Oa copy image. Here, the output order designation button 53↓ signal F is sent to the boat 60 via the boat 54t as the reproduction KFP designation signal F', and is input to the optical head drive circuit as the signal F" to move the optical head and specify The image information is read from the disk in the order in which it is extended.This image information is sent from the playback signal processing path 6b to the port 160 as the main signal M to the port 54 of the printer 4, and then as the signal M' to the laser modulation circuit 58K input. Then, in conjunction with the drum drive circuit 59, a copy image is printed out using a well-known photo process, and the series of sequences is completed.At the time of printing, a copy end signal is sent from the printer 4 to the magneto-optical disk memory device. It is also possible to confirm whether or not the information can be erased in the next sequence by sending it to ff15.In other words, in this embodiment, 11) After the raw processing is finished and immediately before using the magneto-optical disk memory device again , the information recorded on the disc is automatically erased.Also, in this embodiment, an example of erasing the recorded information based on the number of copies is shown, but before manually inputting new image information. The gist of the present invention is not impaired even if erasing is performed based on any signal that can be determined to be used in a magneto-optical disk memory device.

In this embodiment, the erase signal is also issued from the printer, so if any trouble is found in the printer when inputting information manually, the information in the memory will not be erased, and the information that was previously output will be deleted. After checking once again whether there are any deficiencies caused by the above-mentioned trouble, you can take steps such as replenishment.

In the embodiments described above, the operation panel is an independently provided remote control panel, but it may be provided integrally with any of the printer, document reading device, or magneto-optical disk device.

The state of erasing recorded information in the optical disk memory device is briefly explained in FIG. 8 (aχ(bl(cl).
When the exit direction of the recording bit periphery of the disk 9 is the incoming direction of the arrow in the figure, the erasing head 72 consisting of a bar-shaped magnet with the disk side as the S pole and the opposite side as the N pole is positioned above the disk 9 to erase the recording bits. Erase. The erasing pad 72 is retracted from above the disk 9 during recording and reproduction, and is rotated around a rotating shaft 74 by the drive of a motor 73 based on the sorter content erasing command during the sequence.
The disk is stopped at a position where the radial direction of the disk and the longitudinal direction of the erasing head substantially coincide. An example of the control at this time and an example of the control system are shown in FIGS. 8(c) and 8(c), respectively.

gl
When is input, the motor rotates 4M at the specified timing.
r is generated, and based on it, a drive voltage E is applied from the motor drive circuit 75 to the reversible motor 73.
3 rotates. At this time, the erasing head 72 rotates in the direction of arrow B together with the rotating shaft 74 of the motor 730, and at a position where the radial direction of the disk and the longitudinal direction of the erasing head 72 substantially coincide, the microswitch M is turned on, and the signal No. 7 turns on the erasing head 72. Stop motor rotation. Even if the disk 91-L is rotating at this time, it may start rotating after the erasing head has stopped. After the erase head stops, the disk 9 rotates at least once, so that the magnetization direction of the magnetic film of the disk changes to the eighth direction.
This is to erase the information t' recorded on the disk 9 aligned in the direction of the arrow A as shown in FIG. 3(a).

After that, the control circuit 76 sends a signal Er to reversely rotate the remoter.
-B is generated, and the motor drive circuit 75 applies the drive voltage E to the reversible motor 73, causing the motor to rotate in the direction opposite to arrow B, thereby retracting the erasing head from above the disk 9. This rotation is stopped when a microswitch M, which defines the home position of the erasing head, is turned on. Through the above process, the recorded information on the disc is erased. Note that the erasing head has a length that can cover at least t of the recording area in the radial direction of the disk. If the bit width in the radial direction of the disk is 1 μm, the intensity of the magnetic field on the magnetic film generated by the erase head is 1 kOe or more in order to reverse the direction of s-conversion of the bit.

Further, by providing an auxiliary magnetic pole on the opposite side of the magnet and the disk surface, the magnetic flux can be more effectively concentrated in the direction of the arrow. Above, an example was shown in which the erasing means was composed of a permanent magnet, a motor, etc., but as shown in FIG.
7 is fixed above (or below) the disk, and the control circuit 79
The signal Er Ic is passed from the electromagnet power source 78 to the 16 magnet, generates a magnetic field, removes the recorded information, and stops the current flow at No. 46 Er-B. 4. A similar effect can be obtained.

The present invention is not limited to the embodiments described above, and can be modified in various ways. For example, one example of the image information processing method mentioned in the main text is kyi < digits, and the page order designation, order of number of copies, etc. can be changed freely.

Moreover, information processing km t, I' ti based on the present invention
It is limited to a configuration consisting of a document reading device, a magneto-optical disk memory device, and a printer as in the embodiment described in JJ, but it may also be a configuration in which several of these are integrated.
Image information is also limited to that obtained from the document reading device.
The information may be sent from a factor display, a computer output device, or a display device 4.

Also, instead of magneto-optical disk memory device l'(:IC
Other memory means such as memory may also be used.

As explained above, according to the present invention, the image fz i'lt information is stored in the memory, and the processing command e is then transmitted from the memory to the ll! II storage information (11- In conventional image information processing methods and apparatuses such as reading and processing, the data sent from the image forming means until new image information is stored after the playback process is completed/!:). Since the information already stored in the memory means is automatically erased in accordance with the erase instruction signal given, there is no need to worry about leakage of KIJ\fj information, and the stored information can be reliably reproduced.
