Abstract

PURPOSE:To store information from a reader on a disc in real time by providing a disc memory, a reading means which stores image information in this memory, and an interface means which stores read information in this disc memory before completion of read of this reading means. CONSTITUTION:Each buffer in an interface (IF) part has line buffers (LB)201- 224, and write permission signals (LWE signals) and read permission signals (LRE signals) are inputted to them to select input or output of data. For example, data is read out from the LB12 when data is written in the LB1, and data is read out from the LB13 when data is written in the LB2. Though the LB from which data is read out is shifted to the LB13, the LB14, and the LB15 successively during the write to the LB1 if the write speed and the read speed do not coincide with each other, this shift is absorbed unless said LB is shifted up to the LB1. Consequently, printer or disc input and output to a printer or disc are synchronized with each other, and therefore, pictures from the reader are outputted to the disc in real time.

Description

[Detailed description of the invention] [Technical field] The present invention relates to an image processing system.

[Prior Art] Conventionally, when reading information from a reader and storing it on a disk, the information read from the reader is first stored in a page memory or the like, and after being read, the data is sent to a disk device and stored. However, processing time is required to store the data in the memory and read the data, making it difficult to store the data in real time. , [Objective] The present invention has been made in view of the above points, and an object of the present invention is to enable real-time storage of information from a reader onto a disk. □ [Example] An example of the present invention will be described below based on the drawings. FIG. 1 is a perspective view of an overall layout of an embodiment of a processing system according to the present invention. Reference numerals 1 and 2 denote readers for reading original images, and their respective signal lines are connected to the disk device 3. On the empyema panel of the 1-1 reader, operations such as controlling external devices and editing images can be performed using the keys on the panel. Further, 4.5 is a printer, each of which is a disk device (hereinafter referred to as ES) capable of storing a maximum of 100 A4 size images. The ES3 has a reader-side connector section and a printer-side connector section, which will be described later.

In Figure 1-i, two readers 1 and 2 and two printers 4 and 5 are connected to gs3.
Combinations with more or less than the above numbers are also possible.
Up to 4 readers and 8 printers can be connected.

Figure 1-2 (a) shows reader 1 or 2, Figure 1-2 (b)
A structural sectional view of the printer 4 or 5 is shown in FIG.

The original is placed face down on the original glass 6, and its placement reference is on the back left side when viewed from the front. The original is pressed onto the original glass by the original cover 7. The original is illuminated by a fluorescent lamp 8, and the reflected light is reflected by mirrors 9 and 1.
An optical path is formed to condense light onto the surface of the CCI 12 via the lens 11 and the CCI 12. And this mirror 1
o and mirror 9 move at a relative speed of 2:1. This optical unit moves from the left toward the stone at a constant speed while applying PLL using a DC servo motor. The traveling speed is 180 H/
Sec, the return path is 468 mI/sec. This resolution in the sub-scanning direction ζ! Yo16 /1nes/
It is mm. The document thickness that can be processed is A5 to A3, and the document placement direction is A5. B5. A4 size should fit,
1)4. A3 is placed at i*. Then, the return of the optical unit according to the original 41E is performed by counting the +) -i o signal VI DEOENABLE from the image tip sensor and firing when the count value corresponds to the document size.

Next, regarding the main scanning direction, during main scanning, the maximum width of A4 paper will be 297 mm depending on the direction in which the document is placed. and,
In order to resolve this at 16 pel/rm, 4752 (=297x16) bits are required as the number of COD bits, so this device uses two 2688-bit CCD array sensors.

I made it drive in parallel. Therefore, 16 /1nes/
From the conditions of min, 180 parrot/sec, the main scanning period (=
628 347.21. ．． 8. -= 7.7419 Hz.

Next, the outline of the printer shown in FIG. 1-2(b) will be explained. The image signal processed by the reader section and turned into a pit serial is sent to the laser scanning optical system unit 25 of the printer. This unit consists of a semiconductor laser, a collimator lens, a rotating polygon mirror, an Fθ lens, and a tilt correction optical system. The image signal from the reader is applied to a semiconductor laser and undergoes electrical-to-optical conversion, and the diverging laser light is made into parallel light by a collimator lens, and is irradiated onto a multi-body mirror rotating at high speed, thereby directing the laser light to the photoreceptor 26. scan. The rotation speed of this polyhedral mirror is 2.60 Or
It is rotated by pm. During the scanning, there are about 400 gourds, and the effective image is 297 in A4 horizontal size.

Therefore, the signal frequency applied to the semi-integrated laser at this time is approximately 20 N1 (z (N⇠2)). The laser beam from this unit is incident on the photoreceptor 26 via the mirror 24.

The photoreceptor 26 includes, for example, a conductive layer, a photosensitive layer, and an insulating layer 31. Therefore, the process components that make it possible to form Kf& are arranged. 27 is a front charge remover, 28 is a front charge remover 2, 29 is a primary charger, 30
is a secondary charger, 13 is a front exposure lamp, 14 is a developer,
15 is a paper feed cassette, 16 is a paper feed roller, 17 is a paper feed guide, 18 is a registration roller, 19 is a transfer charger, 2
0 is a separation roller, and 21 is a conveyance guide.

22 is a fixing device, and 23 is a tray. The speed of the photoconductor 26 and the conveyance system is the same as the forward path of the reader <18°re/S
It is ec. Therefore, the speed of copying using a combination of a reader and a printer is 30 A4 sheets/minute. Further, printers use a separating belt on the front side to separate the copy paper that is in close contact with the photosensitive drum, but because of this, the image of the belt is missing. If the signal is added to that amount, it will be developed, and the toner will stain the minute/second belt, which will also stain subsequent sheets of paper. At 8m, the video electrical signal for print output is cut off. Also, if toner adheres to the leading edge of copy paper, when it is fixed, it will wrap around the fixing roller and cause a jam, so cut the electrical signal on the reader side to prevent toner from adhering to the leading edge of one sheet of paper. There is.

FIG. 2-1 is a block diagram of the magneto-optical disk device.

The interface 51 controls the interface with external equipment (in this embodiment, an image reading device (reader l, printer)) and controls the operation of the magneto-optical disk 57.Detailed blocks of control on the interface within this sequence controller The diagram is shown below.

The AP-AT circuit 52 always aligns the focal position of the objective lens (not shown) of the optical head helmet onto the magneto-optical disk 61 (autofocus mechanism), and furthermore, during playback, the objective lens always aligns the focal position of the objective lens (not shown) on the magneto-optical disk 61, and furthermore, during playback, the objective lens always aligns the focal position of the objective lens (not shown) on the magneto-optical disk 61. ) This is a circuit that controls the auto tracking mechanism shown above. A detection signal for performing the control is detected by a photo sensor (not shown) in the optical head 58, amplified by a preamplifier 57, and input to the AP-AT circuit S2. This detection signal also includes a reproduction signal of the signal recorded on the disc 58, and is sent to the recording/reproduction signal processing circuit 55 after being amplified by the preamplifier 57.

A laser drive circuit 53 drives a semiconductor laser (not shown) which is the light source of the optical head 58. Record when recording/
The semiconductor laser blinks in response to the recording signal sent from the reproduction signal processing circuit 55.

The head drive motor control circuit 54 controls a head drive motor 59 that moves the optical head 58 in the radial direction of the disk disk 61.

The recording/1q raw signal processing circuit 55 modulates (MFM in this embodiment) L the image f-, which is sent from the reader, which is an external device, and outputs this modulation signal to the laser drive circuit 53 to write the disc. The optical head 58° preamplifier 57 demodulates the reproduced signal and sends it to a printer, which is an external device.

6 spindle motor drive circuits rotate the disk 61 (
The rotation of the spindle motor 60 is controlled to 1800 rpm+n).

When erasing data recorded on the magneto-optical disk 61, the erase head drive circuit 63 drives the erase head 62 in the radial direction of the disk. The configuration of this erasing head is shown in FIG. 2-2.

Reference numeral 62 denotes an erasing head, which is provided on both sides of the magneto-optical disk 61. An electromagnetic coil is wound around its tip,
Erases recorded data by generating magnetic force. Note that the generation of magnetic force is controlled by the erase head drive circuit 63, and also controls the erase head drive motor 62-1. However, since the electromagnetic coils are provided on both sides of the disk, the spread of the magnetic lines of force can be reduced.

FIG. 3-1 shows a block diagram of a portion of the interface 51 shown in FIG. 2-1 that controls the external device interface.

This circuit selects one of the reader 1, reader 2, and disc playback signals and sends that signal to the printer 4.

Or it works to output to multiple sources. This behavior ゛)
The interface management unit 70 is responsible for
The signal lines of each device are connected. The interface management unit 70 obtains a signal from any one of the reader 1, the reader 2, and the magneto-optical disk device 3 according to the command information (command 1 and command 2) sent from the reader 1 and the reader 2, and outputs the printer 4. ．． The printer 5 determines which device 4 of the magneto-optical disk device 3 the signal should be sent to. Data selector 71 is reader 1,

and VSYNC1 and BD 1, VIDEO2 and CLK2
and VSYNC2 and BD2. Playback VIDEO and playback CLK
, reproduction VSYNC, and reproduction BD signals are selected and output to buffer 1 of 73, buffer 2 of 74, and buffer 3 of 75. Further, the buffer 11
Buffer 2. One or more of the buffers 3 is selected, and the printer or magneto-optical disk corresponding to that buffer is activated. Note that buffer 1 corresponds to printer 4, buffer 2 corresponds to printer 5, and buffer 3 corresponds to magneto-optical disk device 3.

The configuration of this buffer is shown in Figure 3-2.

Each buffer has an address counter 230 for recording, an address counter 231 for reproduction, and a line buffer 201 for 24.
~2240It consists of three. The line buffer is, for example, a 4752-bit shift register, into which a VIDEO signal and a VCLK (video clock) signal are input from a data selector, and the VCLK signal serves as a substitute clock for writing the VII) EO times signal. In addition, from the recording address counter 23o and 1+f raw address counter 231, a line signal (hereinafter referred to as L W E (hereinafter referred to as "IT") to permit writing to the sofa, and a signal to permit reading from which line buffer (hereinafter referred to as r & L) are sent.
RE (referred to as No. 73) is manually operated. This LW
Manual input or output of data is selected by the E signal and the I4E signal. The recording address counter 230 is a counter that selects into which line buffer the VIDEO signal selected by the data selector 71 is to be written.
Each time the D times signal is manually input, the LWE signal is selected one by one, and the VIDEO signal is input to the corresponding line buffer.
I get sucked into it. pj raw address kaku y l 23 ],
7/- is a counter that selects from which line buffer the VIDEO signal drawn in is output from aiG, and is used as the BD double signal basic clock from the printer or disk. Each time the BD double signal is input, the LRE signal is selected one by one, and the VIDEO signal is selected from the corresponding line buffer.
Read out the signal. Further, a printer select signal from the interface management section 70 is input to the recording address counter 230 and the reproduction address counter 231, allowing operation of the address counter of the buffer γ corresponding to the desired printer or disk, and changing the address of the other buffers. Prohibit counter operation.

Figure 3-3 is a time chart of writing to the line buffer. When the BD double signal is input to the recording address counter, the L WE n signal (assumed to be written to the line buffer n) is turned ON in synchronization therewith, and the line buffer n becomes ready for writing. When a predetermined time has elapsed after the input of the BD double signal, the VIDEO signal and the VCLK signal are input to the line buffer n and written. next BD
At the rising edge of the double signal, the LW En signal becomes OF'F.
LWEn4-1 turns ON. Therefore, writing to line buffer n is prohibited, and writing to line buffer n+1 is only possible. In this way, the writable line buffer is shifted every time the BD double signal is input. FIG. 3-4 is a time chart showing the timing of writing and reading -4 to the line buffer. For example, when data is being written to line buffer 1, data is read from line buffer 12, and when data is being written to line buffer 2, data is read from line buffer 13. Also, if the input speed and ml output speed do not match, the line buffer to be read when writing to line buffer 1 will shift from 13-→14→15 or 12→11→lO, but line buffer 11 As long as there is no deviation, the deviation can be absorbed.

Therefore, it is possible to synchronize human power from the printer or disk with output to the printer or disk, so that images from the league or disk can be output or recorded to the printer or disk in real time. Also,
Contrasting with each printer or disk: Because it has a separate buffer, it can output to multiple printers or disks at the same time.

The ES control section 72 is a section that controls the operation of the magneto-optical disk device 3. Furthermore, a signal for a recording operation of the magneto-optical disk is input to the interface management section by the print select signal.

A signal from the magneto-optical disk is input to the interface management section by the league select signal.

That is, magneto-optical disk device K, 3 is a playback operation.

It functions as a league or a printer depending on the recording operation.

76 is a clock generator that reduces the clock for starting from the buffer by -1 (3). 77 is a pseudo BD generator that counts the clock of the clock generator 76 for one line and calculates the clock when writing to the disc. A column 70 for generating a BD double signal is included in the magneto-optical disk device 3.

For a 4-coupled BD that is read from the disk and rinsed, the signal obtained by detecting the beam every time the printer scans one line of rate is fine, but even a pseudo BD like the one mentioned above will still be a 1:1 signal. . ? In the case of a viewer, the -(output it'h'+1 degree) difference due to the fluctuation of the laser beam can be prevented.Next, the operation of the sequence controller 51 will be explained.

FIG. 4 is a flowchart 1-4 of key manual processing of the sequence controller 51. First, if we have key personnel from the league club, we will determine whether it is in E8 mode (currently recorded on a magneto-optical disk or played back) or if it is a sake cup (S'l'lNP 81
