Abstract

PURPOSE:To manage updating only at one place when the information of a secondary storage means is updated, and to eliminate the difference of response speed between each terminal equipment and another, and to prevent trouble that the secondary storage means can not be accessed because of the fault of another terminal equipment. CONSTITUTION:A secondary storage part 7 stores the information to be transferred to the primary storage parts 10a to 10b of the terminal equipments 2a to 2b. A receiving part 5 receives an information transfer request from the terminal equipments 2a to 2b. A using right deciding part 6 decides whether the operator of the terminal equipment can use the information for which the transfer request is received or not. A transmitting part 4 transfers the information requested to transfer in the secondary storage part 7 to the terminal equipments 2a to 2b.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a secondary storage device in an information processing system.

0002

2. Description of the Related Art Conventional secondary storage means, as shown in FIG.
1a to 11b as a secondary storage unit, and the information stored in the secondary storage units 14a to 14b is stored in the terminal device.
It was transferred and used only to the next storage units 13a to 13b. Further, as shown in FIG. 3, the information stored in the secondary storage unit 20 built into some terminal devices 15 as a secondary storage means is only transferred to the primary storage unit 19 of the terminal device 15. Instead, the primary storage unit 2 of the other terminal devices 16a to 16b
2a to 22b share the information, access is made via the communication network 17 as necessary, and the transferred information is shared by the receiving units 21a to 22b.
I received and used it on 1b.

[Problems to be Solved by the Invention] In the terminal devices in the conventional information processing system described above, in the case of FIG. When information is updated in one of the terminal devices, the information in the built-in secondary storage section of the other terminal devices must also be updated in the same way, which has the drawback of being cumbersome. was.

In addition, in the case of FIG. 3, although the secondary storage section is shared by multiple terminal devices, the terminal device that has a built-in secondary storage section and the terminal device that does not have a built-in secondary storage section have a built-in The terminal device that is not connected to the network is slower because it has to transfer information via the communication network, and the access response speeds are different between the two terminal devices, so there is no equality.
This has the disadvantage that when a terminal device with a built-in secondary storage section becomes a failure, a terminal device without a built-in secondary storage section will be unable to access the secondary storage section.

[0005] The object of the present invention is to update information in the secondary storage means by only updating it in one place, and to ensure that there is no difference in response speed between terminal devices and that the response speed is equal. An object of the present invention is to provide a secondary storage device in an information processing system that can prevent the secondary storage means from becoming inaccessible due to a failure of a terminal device.

[0006]

[Means for Solving the Problems] A secondary storage device in an information processing system of the present invention is a secondary storage device in an information processing system configured by connecting a plurality of terminal devices having primary storage means to a communication network. (A) secondary storage means for storing information transferred to the primary storage means; (B)
) receiving means for receiving information transfer requests sent from each of the terminal devices; (C) information transfer requested about the user can be used from a user recognition code included in the information transfer request; (D) a transmitting means for transmitting the information in the secondary storage means to which the transfer request has been made to the terminal device.

[0007]

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a secondary storage device in an information processing system of the present invention.

As shown in FIG. 1, the secondary storage device 1 in the information processing system of this embodiment includes a plurality of terminal devices 2a.
~2b is connected to the communication network 3, and the terminal device 2a
A secondary storage unit 7 that stores information to be transferred to the primary storage units 10a to 10b of ~2b, and a transmitting unit 8 of the terminal devices 2a to 2b.
Receiving unit 5 receives the information transfer request sent from a to 8b, and determines from the user recognition code included in the information transfer request whether or not it is possible to use the information for which the transfer request has been made regarding the user. The usage right determination unit 6 transfers the requested information in the secondary storage unit 7 to the primary storage unit 1 of the terminal devices 2a to 2b.
It is composed of a transmitting section 4 that transmits data to 0a to 10b via receiving sections 9a to 9b.

Next, the operation will be explained.

In FIG. 1, for example, when the operator of the terminal device 2a uses information stored in the secondary storage unit 7 of the secondary storage device 1, the information stored in the secondary storage unit 7 of the secondary storage device 1 is transmitted from the transmitting unit 8a of the terminal device 2a to In response, an information transfer request requesting to transfer the information stored in the secondary storage unit 7 is transmitted via the communication network 3. The information transfer request sent from the terminal device 2a to the secondary storage device 1 is input to the receiving unit 5 of the secondary storage device 1. The information transfer request input to the receiving unit 5 is input as is to the usage right determining unit 6, and
Based on the user identification code included in the information transfer request from a, it is determined whether or not the operator of the terminal device 2a can use the information for which the transfer request was made. and,
When it is determined that the information stored in the secondary storage unit 7 can be used by the operator of the terminal device 2a, 2
Next, the specified information stored in the storage section 7 is read out and output to the transmission section 4.

The transmitter 4 of the secondary storage device 1 transmits the input transfer information to the terminal device 2a via the communication network 3. The sent information is received by the receiving section 9a of the terminal device 2a. Transfer information received by the receiving section 9a from the secondary storage device 1 is sent to the primary storage section 10a and stored therein.

[0013] In this way, by allowing each terminal device to share the secondary storage means and making it independent from each terminal device,
When updating the information in the secondary storage means, it only needs to be updated in one place, and there is no difference in response speed between each terminal device.
There is no longer a possibility that the next storage means cannot be accessed.

[0014]

Effects of the Invention As explained above, the secondary storage device in the information processing system of the present invention uses the secondary storage means as
The secondary storage means is not built into the terminal device but is provided independently and connected to the communication network.In this way, the secondary storage means can be shared by each terminal device, and by making it independent from each terminal device, , when updating the information in the secondary storage means, it only needs to be updated in one place, and there is no difference in response speed between each terminal device. This has the effect of preventing access from becoming inaccessible.
