DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing system, a data acquisition device, and a data processing device for handling data relating to a document, and more particularly to a document processing system suitable for implementing a document copy function via a network. And a data acquisition device and a data processing device.

2. Description of the Related Art In recent years, with the spread of personal computers (hereinafter abbreviated as "PC"), the amount of work for copying paper documents with a copying machine has been reduced in general offices and the like.
Conversely, documents created on a PC can be transferred to a LAN (Local Area Network
rk) and the like, the amount of work for printing with a printer device on a network tends to increase. In addition, there has been a considerable need to convert an image printed on paper into electronic image data and use it on a PC. To cope with this, a scanner device is installed on a network and the scanner is installed. It is becoming increasingly common to share a device with a plurality of PCs.

In such a network environment, for example, a utilization form in which a scanner device and a printer device on a network are combined and used for copying a paper document can be realized. That is, the scanner device uses the function of transferring image data to the PC via the network and the printer device using the function of receiving image data from the PC via the network and printing the image data. Is transferred to a printer for printing, a copying function for a paper document can be realized without the need for a copying machine.

According to the copying function realized in this way (hereinafter referred to as "network copying function"), although the speed, efficiency, operability, and the like are inferior to those of a copying machine using a conventional copying machine, the copying machine can be used. Since it is not necessary, it is very advantageous in terms of cost and space saving. However, in terms of speed, efficiency, operability, and the like, it is considered that this does not significantly affect daily work in an office or the like in view of the situation where the amount of copying work is decreasing.

[0005]

However, in the above-described conventional network environment, a large amount of image data flows on the network by the network copy function. In other words, in order to realize the network copy function, image data is exchanged between the scanner device and the printer device via the network, thereby causing a problem of increasing network traffic.
This is true not only between the scanner device and the printer device, but also for data transfer between them and the PC.
There is a risk of adverse effects.

Accordingly, the present invention has been made in view of such a problem, and, for example, even if a network copy function is realized, an efficient data transfer is performed without increasing network traffic. It is an object of the present invention to provide a document processing system, a data acquisition device, and a data processing device that make it possible.

[0007]

According to the present invention, there is provided a document processing system devised to achieve the above-mentioned object, wherein at least one of a function of acquiring data relating to a document and a function of storing the data in advance. A data acquisition device having a function of receiving data relating to a document from the data acquisition device and performing a predetermined process;

And a selecting means for selecting which of the first communication line and the second communication line should perform the transmission when transmitting data relating to a document from the data acquisition device. It is characterized by having.

Further, the present invention is a data acquisition device devised to achieve the above object, which has at least one of a function of acquiring data relating to a document and a function of storing the data in advance. In addition to the data acquisition device, a data processing device having a function of receiving data related to a document from the data acquisition device and performing a predetermined process, and connected to the data acquisition device and the data processing device, and A first communication line for constructing a network system comprising: a second communication line for locally connecting the data acquisition device and the data processing device separately from the first communication line; and Selection for selecting whether the transmission is performed via the first communication line or the second communication line when transmitting data relating to the document. It is characterized in that used in the document processing system that includes a stage.

According to another aspect of the present invention, there is provided a data processing device devised to achieve the above object, having a function of receiving data relating to a document and performing a predetermined process.
In addition to the data acquisition device, a data acquisition device having at least one of a function of acquiring the data and a function of storing the data in advance is connected to the data acquisition device and the data processing device.

Things.

In the above-structured document processing system, data acquisition device or data processing device, the data acquisition device has a function of acquiring or preliminarily storing data relating to a document, for example, a scanner having a function of spooling image data. The device corresponds to this. The data processing apparatus has a function of performing predetermined processing on data relating to a document, and corresponds to, for example, a printer apparatus that prints out image data. Therefore, if data is transferred from the data acquisition device to the data processing device, for example, a network copy function can be realized. However, the data acquisition device and the data processing device are connected by both the first communication line forming the network system and the local second communication line, and the selection means selects either one of them. It is supposed to. Therefore, for example, when the second communication line is selected for data transfer from the data acquisition device to the data processing device, and in other cases, the first communication line is selected, the network copy function is realized. At that time, a large amount of data does not flow on the first communication line.

09 and the function as the IEEE1394 control unit 210 are realized.

Next, an example of a processing operation in the document processing system configured as described above will be described. First, an example of a processing operation in the scanner device 1 will be described.

In the scanner device 1, the scanning unit 16 is driven to acquire image data from an original document.
There are three types of image data acquisition: one for "copy", one for "network scan", and one for "local scan". These are all instructed through operation of the operation panel 14 by the user.

FIG. 6 is an explanatory diagram showing a specific example of display on the operation panel of the scanner device. For example, FIG.
As shown in the figure, the scan instruction by the user is "copy"
In this case, the scanner device 1 acquires image data from the original document in order to print out the image drawn on the original document by the printer device 2 as it is.
That is, image data is acquired as part of realizing the network copy function. At this time, the operation panel 14
In the above, information necessary for print output by the printer device 2, specifically, information on the paper size, the number of print copies, and the like is also input.

As shown in FIG. 6B, for example, when the scan instruction by the user is "network scan", the scanner 1 converts the image drawn on the original document into electronic image data. In order to convert the original document into a document and process it on the PC 3, image data is acquired from the original document. At this time, on the operation panel 14, information necessary for specifying the PC 3 that processes data, specifically, a URL (Uniform Resource Locato
Information on r) etc. is also input.

In addition, as shown in FIG. 6C, when the scan instruction by the user is “local scan”, the scanner 1 temporarily stores the image drawn on the original document in the confidential box. For this purpose, image data is acquired from the original document. At this time,
On the operation panel 14, information necessary for storing data in the confidential box, specifically, information on the box number (or memory address) of the confidential box is also input.

FIG. 7 is a flowchart showing an example of the processing operation when the scanner device acquires image data. Hereinafter, description will be given along this flowchart.
When acquiring image data from a manuscript document, the scan control unit 103 receives various scan instructions from the panel control unit 101 (step 101; hereinafter, steps are abbreviated as “S”).

If the received instruction is "copy" (S102: Yes), the scan control unit 103
Acquires the IP address of the printer device 2 connected via the IPv4-over-IEEE1394 control unit 109 (S1).
03). At this time, the scan control unit 103 sets the IPv4-over-
The reason why the IP address is obtained via the IEEE1394 control unit 109 is that it is set in advance that the data transfer between the scanner device 1 and the printer device 2 is performed via the second communication line 5 at the time of “copy”. is there.

When the IP address of the printer device 2 is obtained, the scan control unit 103
Is driven to optically read the original, and the obtained bitmap image data is transmitted to the transmission unit 105, the TCP / IP protocol stack 107, the IPv4-ove
The data is transmitted to the printer device 2 connected via the second communication line 5 via the r-IEEE1394 control unit 109 and the IEEE1394 control unit 110 (S104).

In the case where the instruction received from the panel control unit 101 is "network scan" (S1
05: Yes), and if the use of the proxy server (proxy server) is set in advance in the setting information area 102 (S106: Yes), the scan control unit 103 The IP address of the proxy server is read from (S107). However, if the use of the proxy server is not set in advance (S106: No), the scan control unit 103
Uses, for example, DNS (Domain Name System)
The IP address of the URL input from the operation panel 14 is obtained (S108).

When the IP address of the proxy server or the input URL is obtained, the scan control unit 1
Numeral 03 drives the scanner unit 16 to optically read the original, and transmits the obtained bitmap image data via the transmission unit 105, the TCP / IP protocol stack 107, and the Ethernet control unit 108. The data is transmitted to the PC 3 or the like connected via the first communication line 4 (S
104).

If the instruction received from panel control section 101 is "local scan" (S105:
No), the scan control unit 103 drives the scanner unit 16 to optically read the original, and stores the bitmap-like image data obtained by this in correspondence with the confidential box number specified from the operation panel 14. It is stored in the area 104 (S109).

The image data stored in the storage area 104 is transmitted, for example, to the request source when a request is made from the PC 3. FIG. 8 is a flowchart illustrating an example of a processing operation when the scanner device temporarily stores image data and then transmits the image data. Hereinafter, description will be given along this flowchart.

The request for image data in the confidential box is received by the reference receiving unit 106. The request received by the reference receiving unit 106 includes a reference request for requesting a list of confidential boxes and a request for a document in the confidential box. There are a reference request for requesting a list and a transmission request for requesting transmission of a specific document in the Mailbox.

For example, the Ethernet control unit 108 and the TCP /
The first communication line 4 via the IP protocol stack 107
When a reference request is received from the PC 3 above (S20
1) In the reference receiving unit 106, when the content of the reference request is a list request of the confidential box (S202: Yes),
The confidential box list is transmitted to the requesting PC 3 (S203). If the content of the reference request is not a confidential box list request but a document list request in the confidential box (S204: Yes), and the confidential box indicated in the request exists in the storage area 104 (S20).
5: Yes), the reference receiving unit 106 transmits the document list related to the request to the requesting PC 3 via the TCP / IP protocol stack 107 and the Ethernet control unit 108 (S206). However, when the confidential box indicated in the request does not exist (S205: No), the reference reception unit 106 notifies the fact via the TCP / IP protocol stack 107 and the Ethernet control unit 108. An error message is transmitted to the requester PC3 (S
210).

On the other hand, if the request is a document transmission request (S207: Yes) and the confidential box specified in the request exists, and if the requested document exists in the confidential box, (S208: Yes), the reference receiving unit 106 checks the TCP / IP protocol stack 107 and
The data relating to the requested document is transmitted to the requesting PC 3 via the Ethernet control unit 108 (S20).
9). However, the confidential box specified in the request, or
If the requested document does not exist in the confidential box (S
208: No), the reference receiving unit 106 transmits an error message for notifying the fact to the requesting PC 3 via the TCP / IP protocol stack 107 and the Ethernet control unit 108 (S210).

Here, the PC on the first communication line 4
3 has been described as an example, the document in the confidential box has been referred to from the printer 2 connected via the second communication line 5. Etc. may be performed. The communication in this case is performed by the IEEE1394 control unit 110, the IP-v4-over-EEE
This is performed via the 1394 control unit 109 and the TCP / IP protocol stack 107. That is, when transmitting document data or the like in the confidential box to the printer device 2, the transmission is performed through the second communication line 5 according to the preset settings.

The specification of a confidential box, a document, and the like at the time of a reference request or the like may be performed by using the first method. However, it is also conceivable that the instruction is made by a URL or a command added to the URL.

Next, an example of a processing operation in the printer device 2 to which image data is transmitted from the scanner device 1 performing the above processing operation will be described. FIG. 9 is a flowchart illustrating an example of a processing operation when the printer device receives image data and prints out the image data. Hereinafter, description will be given along this flowchart.

In the printer device 2, when the receiving unit 204 receives a print request (S301), a print output process according to the print request is started. Print request is Et
hernet control unit 208 and TCP / IP protocol stack 2
07 from the PC 3 on the first communication line 4, or
IEEE1394 control unit 110, IP-v4-over-EEE1394 control unit 10
9. Accepted from the scanner device 1 connected via the second communication line 5 via the TCP / IP protocol stack 107. The print request includes a normal print request to which data to be printed and output (PDL data, image data, and the like) is sent together, and a URL print request to which data to be printed and output is not sent.

For example, if the content of the print request received by the receiving unit 204 is a request for normal printing, that is, if data to be printed out is transmitted following the request (S302: (Yes), the receiving unit 204 receives the subsequent data (S30).
3). Here, the developing unit 206 converts the data received by the receiving unit 204 into the print engine control unit 2 as necessary.
The image is developed into bitmap data, which is a data format 03 can support (S304). Then, the print engine control unit 203 outputs the bitmap data into which the image has been developed or the image data received by the receiving unit 204 to the print engine 28, and causes the print engine 28 to perform print output processing (S305). The reception (S303), expansion (S304), and output (S305) described here may be executed in parallel.

For example, if the content of the print request received by the receiving unit 204 is a request for URL printing, that is, if the request merely specifies the URL of the document (S306: Yes),
Data to be printed out is not sent. for that reason,
The reference request unit 205 includes the Ethernet control unit 208 and the TCP /
Via the IP protocol stack 207, the specified U
Access RL. Then, the document data related to the print request is referred from the access destination (S307). At this time, the access destination often does not match the request source of the print request. Therefore, reference to the document data may not be permitted.

When the reference by the reference request unit 205 is permitted (S308: Yes), the expansion unit 206 expands the data related to the reference into bitmap data as needed (S304). Then, the print engine control unit 203 causes the print engine 28 to perform a print output process of the data (S305). In addition, reference is made here (S307), development (S304), output (S305).
May be executed in parallel.

When URL printing is requested, the URL of the confidential box of the scanner 1 may be specified as the URL of the document. In this case, the reference request unit 205 transmits the TCP /
Reference is made via the IP protocol stack 207, the IPv4-over-IEEE1394 control unit 209, and the IEEE1394 control unit 210. That is, the reference request unit 205 performs the reference through the second communication line 5. Even in this case, the subsequent expansion (S304) and output (S305) are substantially the same as described above.

If the data to be printed out cannot be referred to correctly (S308: No), or if the content of the print request is an unauthorized request that is neither normal print nor URL print (S306: No), the print output process is executed. Cannot be performed, the receiving unit 204 or the reference requesting unit 20
5 transmits an error for notifying the request source of the print request (S309). At this time, if the request source is the PC 3 on the first communication line 4, the error transmission is performed via the TCP / IP protocol stack 207 and the Ethernet control unit 208. On the other hand, if the request source is the scanner device 1 connected via the second communication line 5, the error transmission is performed by the TCP / IP protocol stack 207 and the IPv4-o.
This is performed via the ver-IEEE1394 control unit 209 and the IEEE1394 control unit 210.

As described above, in this embodiment, a network copy function can be realized by transferring data from the scanner device 1 to the printer device 2. However, the connection between the scanner device 1 and the printer device 2 is established by both the first communication line 4 and the second communication line 5. When data transfer from the scanner device 1 to the printer device 2 is performed, for example, when "copy" is instructed on the operation panel 14, the second communication line is used as the data transfer route according to the preset settings. 5 is to be selected.

Therefore, in the network environment described in the present embodiment, even when the network copy function is realized, a large amount of data does not flow on the first communication line 4 that constructs the LAN. For this reason, the traffic of the network is not increased, so that efficient data transfer can be realized, and various network functions can be provided at the same time.

In the present embodiment, the first communication line 4 and the second communication line 5 perform data transfer according to the same communication protocol while being managed by the TCP / IP protocol stacks 107 and 207. Has become. Therefore, the first communication line 4 and the second communication line 5
It is possible to cope with the data transfer by the two systems with the same software configuration. Efficient data transfer can be realized only by selecting a route without the need to replace software. In addition, since there is no need to prepare a new communication protocol or the like, changes from a conventional network environment can be performed very easily.

In the present embodiment, when data is transmitted from the scanner 1 to the printer 2, the data is transmitted via the second communication line 5. In other cases, that is, when the scanner 1 transmits the data to the printer 2. When sending data to a PC 3 or the like other than the first communication line 4
Done through. Therefore, when implementing the network copy function, it is necessary to transfer image data with a relatively large data amount.In this case, however, it is necessary to prevent the image data from adversely affecting network traffic. In addition, since the image data can be efficiently transferred, it is particularly suitable for realizing a copy function that requires immediacy.

It should be noted that which of the first communication line 4 and the second communication line 5 is used for data transfer is not limited to the mode described in the present embodiment. In other words, if selective data transfer can be performed between the first communication line 4 and the second communication line 5, network impossibility can be reduced and the efficiency of the data transfer can be improved.

In this embodiment, the first communication line 4 and the second communication line 4 are used for data transfer, for example, when "copy" is instructed on the operation panel 14, the second communication line 5 is selected. Although a case has been described as an example in which one of the communication lines 5 is selected is preliminarily set, for example, it is conceivable that the user can arbitrarily select from the operation panel 14. These selections (mode selection described in the present embodiment and arbitrary selection of a communication path by the user)
May be performed on the operation panel 24 of the printer device 2 or on the operation screen of the PC 3 instead of on the operation panel 14 of the scanner device 1. Further, a function for detecting the amount of data traffic in the first communication line 4 is provided. For example, if the detection result is equal to or larger than the threshold, the second communication line 5 is selected. May be determined.

Further, in the present embodiment, the case where the first communication line 4 for constructing the LAN complies with the Ethernet standard is described as an example.
reaNetwork), and of course, may be one that supports a protocol other than Ethernet. For example, the token ring (Toke
n-Ring), ATM (Asynchronous Transfer Mode), X.R. The same can be said for 25 and the like.

Further, in the present embodiment, the second communication line 5
Although the above is an example in which IEEE 1394 is used, any other interface may be used as long as the interface connects the scanner device 1 and the printer device 2 locally. More specifically, USB (Universal Serial Bus) of a serial bus format similar to IEEE1394, SCSI (Small Computer System Interface) of a parallel bus format, RS-232C which is a serial bidirectional interface,
It is conceivable to use another bidirectional interface (for example, a parallel interface).

In the present embodiment, since the IEEE1394 is used as the second communication line 5, both the scanner 1 and the printer 2 have the IPv4-over-IEEE1394 control units 109 and 209. This IPv4-over-IEEE
The 1394 control units 109 and 209 are modules for enabling TCP / IP to communicate on IEEE1394. Therefore, when an interface other than IEEE1394 is used as the second communication line 5, the IPv4-over-IEEE1394 control unit 10 is not necessarily used.
9,209 is not required. For example, if RS-232C is used instead of IEEE1394, SLIP
(Serial Line Internet Protocol) and PPP (Point-t
o-point Protocol).

Even in the case of realizing a copy function by combining with a data processing device, for example, efficient data transfer can be performed without increasing network traffic at the time of executing the function.
