Abstract

A user information registration program 68 of PC3 obtains current time from a built-in timer. Sequentially, the user information registration program 68 extracts one registration destination information from a registration destination table. The user information registration program 68 calculates lease end time from the sum of lease period and registration response reception time in extracted registration destination information and compares the calculation result with current time. If current time exceeds lease end time, the user information registration program 68 adds the IP address of network scanner 2 relating to the current registration destination to a response table 120. Sequentially, user information of PC3 is registered to the network scanner 2 (registration destination). The user information registration program 68 registers new user information to all registration destinations (network scanners 2) registered in the registration destination table.

Claims

1. An image information transmitting system comprising:

a user terminal apparatus which obtains an IP address on an IP network; and

a scanner apparatus which transmits image information to said user terminal apparatus using said IP address,

wherein said user terminal apparatus registers said obtained IP address to said scanner apparatus and re-registers said IP address to said scanner apparatus when a lease period of said IP address elapses.

2. The system according to claim 1, wherein information relating to said lease period is decided by said user terminal apparatus, and said decided information is sent to said scanner apparatus from said user terminal apparatus.

3. The system according to claim 2, wherein information relating to said lease period is sent to said scanner apparatus from said user terminal apparatus using a connectionless typed communication protocol.

4. The system according to claim 3, wherein said connectionless typed communication protocol is a UDP protocol.

5. A scanner apparatus which transmits image information to a user terminal apparatus which obtains an IP address on an IP network using said IP address comprising:

a user terminal IP address acquiring section which acquires said IP address obtained by said user terminal apparatus based on a notification sent from said scanning apparatus;

an IP address storing section which stores said acquired IP address; and

an IP address managing section which deletes said stored IP address from said IP address storing section when a lease period of said IP address elapses.

6. The apparatus according to claim 5, wherein information relating to said lease period is sent to said scanner apparatus from said user terminal apparatus.

7. The apparatus according to claim 6, wherein information relating to said lease period is sent to said scanner apparatus from said user terminal apparatus using a connectionless typed communication protocol.

8. A user terminal apparatus comprising:

an IP address acquiring section which acquires an IP address on an IP network; and

an IP address registering section which registers said acquired IP address to a scanner apparatus,

wherein said IP address registering section re-registers said IP address to said scanner apparatus when a lease period of said acquired IP address elapses.

9. An image information transmitting method which transmits image information to a user terminal apparatus which obtains an IP address on an IP network from a scanner apparatus using said IP address,

wherein said IP address obtained by said user terminal apparatus is registered to said scanner apparatus and said IP address is re-registered to said scanner apparatus when a lease period of said IP address elapses.

10. The method according to claim 9, wherein information relating to said lease period is decided by said user terminal apparatus, and said decided information is sent to said scanner apparatus from said user terminal apparatus.

11. The method according to claim 10, wherein information relating to said lease period is sent to said scanner apparatus from said user terminal apparatus using a connectionless typed communication protocol.

12. The method according to claim 11, wherein said connectionless typed communication protocol is a UDP protocol.
