Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring scan data, and more particularly to a method for transferring scan data applied to a system in which an image scanner device and a plurality of terminal processing devices are connected to a network. .

[0002]

2. Description of the Related Art Conventionally, an image scanner device is directly connected to a user terminal processing device using various interfaces, for example, an interface such as a SCSI, a printer parallel port, or a serial port (RS232C). By pre-scanning using the utility software, roughly align the scanned document, and after scanning by the main scan, temporarily store the obtained data, or
A usage form in which read data is subsequently edited and used is common.

In the connection using these interfaces, there is a restriction that the scanner device and the user terminal processing device must be installed at a short distance due to the limitation of the cable length, and the usage form is limited. Further, in such a configuration, one image scanner device is arranged in one terminal device, so that there is a one-to-one correspondence, so that if there are a plurality of terminal devices, a plurality of image scanner devices are arranged. .

However, the frequency of reading data using the image scanner device is not so high in each terminal device, so that the usage rate is low, and it is not efficient in using resources. Here, the usage rate is a ratio of the actual operation time of the image scanner device to the total operation time of the terminal device. Therefore, there is a widespread use of a system in which a plurality of terminal devices and a small number of image scanner devices are connected to a network, and the system as a whole has an N-to-one correspondence, thereby increasing the use rate of the image scanner devices and efficiently using resources. It has been introduced.

[0005]

By the way, in the above-mentioned system, although the network of the interface is realized, the use form of the image scanner is not changed. That is, the user moves from the terminal to the image scanner device placed at a remote distance and operates the image scanner device. Therefore, the longer the distance from the terminal to the image scanner apparatus, the longer the document holding time from setting the document to scanning to remove the document, which is inconvenient for shared use on a network. Therefore, there was a problem that the characteristics of the network could not be used.

In order to shorten the document holding time,
A configuration is introduced in which a server device with a large-capacity storage function is connected to the network, the read scan data is temporarily stored in the server device, and then the original is immediately released to allow other users to use it. Was done.

[0007] Such an image scanner device that stores scan data in a server is called a network image scanner device. However, a server device is always required, that is, the server device must always be started up. There is a problem that the type of terminal is limited depending on the type of network OS of the server device.

Further, in addition to the traffic based on the data transfer from the image scanner device to the server device, data retransfer traffic from the server device to the terminal device is further generated. Had also occurred.

As described above, the stand-alone method of use is directly applied to a network image scanner apparatus in which the place where the image scanner apparatus is located and the user terminal are separated and shared by a plurality of users. In this case, in addition to the drawback that the shared use efficiency of the image scanner device is not improved due to the increase in the waiting time due to the increase in the document holding time as described above, the security From the viewpoint, there has been a problem that file protection by user identification is required.
