COMMUNICATION DEVICE
First Claim
1. A communication device, comprising:
- communication means which performs, when the communication means is coupled to a computer, data communications between the computer and an external unit;
communication control means which causes the communication means to establish a connection to a file server which is specified in advance as a communication destination, every time a predetermined condition is satisfied;
data reception and transmission instructing means which instructs, when the connection to the file server is established, the communication control means to cause the communication means to obtain at least one file and directory information related to the at least one file, which are stored in the file server, and stores the at least one file and the directory information in a storage area; and
pseudo storage device means which notifies, when the communication means is coupled to the computer, the computer that the communication means is a mass storage class device to cause the computer to recognize the communication device as the mass storage class device, submits the directory information stored in the storage area to the computer, refers, when designation of a file contained in the directory information is accepted from the computer, to the directory information to read the file from the storage area, in which the file is stored, and sends the file to the computer.

Abstract
The communication device includes: a communication control section which periodically causes a radio communication module to establish a connection to the server; a data reception and transmission instructing section which instructs the communication control section to obtain files and directory information stored in the server when the connection is established, and stores the files and the directory information in memories; and an emulation processing section which notifies, when the communication device is coupled to the computer, the computer that the communication device is a mass storage class device, submits the directory information stored in the memories to the computer, refers, when designation of a file contained in the directory information is accepted from the computer, to the directory information to read the file from the memories, and sends the file to the computer.

10. A communication device, comprising:
-
communication means which performs, when the communication means is coupled to a computer, data communications between the computer and an external unit; a volatile memory; a non-volatile memory; communication control means which causes the communication means to establish a connection to a file server which is specified in advance as a communication destination, every time a predetermined condition is satisfied; external data acquisition means which instructs, when the connection to the file server is established, the communication control means to cause the communication means to obtain a plurality of electronic tallies into which at least one file stored in the file server is divided, stores part of the plurality of electronic tallies which constitute the file in the volatile memory, and stores remaining part of the plurality of electronic tallies in the non-volatile memory; and pseudo storage device means which searches, when the communication means is coupled to the computer, and when designation of a file is accepted from the computer, the volatile memory and the non-volatile memory for a plurality of electronic tallies which constitute the file, decodes, when all of the plurality of electronic tallies which constitute the file are found, the file from the plurality of electronic tallies which constitute the file, and sends the file to the computer.
