Information processing apparatus with network communication function and information access employed in the apparatus
First Claim
1. An information processing apparatus comprising:
- network communication means which can be connected to a network for taking, from a server on the network, an information item discriminated by an identifier dedicated thereto;
storage means for storing the information item with a creation date or a storage date attached thereto;
a display unit for displaying the information item;
an input unit for adding another information item to the displayed information item;
unaccessed-information management means for registering therein, in a first state in which an information item having the same identifier as an information item tried to be accessed when the information processing apparatus could not be connected to the network is not stored in the storage means, the same identifier, the registered same identifier being used when the information processing apparatus is connected to the network; and
old information access management means for registering therein, in a second state in which an information item having the same identifier as an information item tried to be accessed when the information processing apparatus could not be connected to the network is stored in the storage means, the same identifier, the registered same identifier being used when the information processing apparatus is connected to the network.

Abstract
If an information item tried to be accessed during traveling is stored in a memory unit, an identifier indicating the information item is registered in an unaccessed-information management unit. If, on the other hand, the information item is stored in the memory unit, the information item is displayed and the identifier is registered in an old information access management unit. When a portable information processing apparatus has come to be able to be connected to a network, an information item indicated by the identifier registered in the unaccessed-information management unit is taken in from a server. Further, whether or not the information item indicated by the identifier registered in the old information access management unit is of an updated version is determined on the basis of the storage date of the information item and the creation date of the information item stored in the server and indicated by the identifier. If the information item is not of the updated version, the information item stored in the server is taken in. As a result, the updated version of an information item tried to be accessed when the information processing apparatus could not be connected to the network can be effectively taken in when the processing apparatus has been connected to the network.

18. An information access method employed in an information processing apparatus which can be connected to a network for taking, from a server on the network, an information item discriminated by an identifier dedicated thereto, and storing the information item, comprising the steps of:
-
storing the information item with a creation date or a storage date; registering, in a first state in which an information item having the same identifier as an information item tried to be accessed when the information processing apparatus could not be connected to the network is not stored in the information processing apparatus, the same identifier; registering and displaying, in a second state in which an information item having the same identifier as an information item tried to be accessed when the information processing apparatus could not be connected to the network is stored in the information processing apparatus, the same identifier; and taking in, through the network, an information item stored in the server and indicated by the identifier registered in the first state, and determining whether or not the information item stored in the information processing apparatus and indicated by the identifier registered in the second state is of an updated version, on the basis of a date attached to the information item stored in the information processing apparatus and a creation date of an information item currently stored in the server and indicated by the same identifier as that of the information item stored in the information processing apparatus, thereby taking in, from the server through the network, the information item of the updated version if the information item stored in the information processing apparatus is older than the information item of the updated version, when the information processing apparatus is connected to the network.
