Abstract

There is provided a discrete type portable visual terminal system, in which a mobile device and a portable visual terminal are connectable/separable, and easier data administration of an address file is achieved. The discrete type portable visual terminal system comprises a mobile device and a portable visual terminal, each including a controller (CPU), a nonvolatile memory (ROM) for storing address data, a keyboard for inputting data, and an external interface driver. On the occasion when the mobile device and the portable visual terminal are connected, address data are automatically transferred/downloaded from one address file to the other address file, thus enabling the mobile device and the portable visual terminal to share the address data.

Claims

1. A discrete type portable visual terminal system comprising a connectable/separable mobile device and a portable visual terminal, each of which includes a controller, a memory for storing address data and an external interface driver, wherein:

address data stored in the memory of the mobile device or the portable visual terminal are transferred to the other memory via the external interface drivers to be shared between the mobile device and the portable visual terminal.

2. A discrete type portable visual terminal system as claimed in claim 1, wherein only the mobile device includes an address data input means such as a keyboard and a software keyboard, and address data of the mobile device are transferred to the portable visual terminal.

3. A discrete type portable visual terminal system as claimed in claim 1, wherein the address data of the mobile device are automatically transferred to the portable visual terminal when the mobile device and the portable visual terminal are connected.

4. A discrete type portable visual terminal system as claimed in claim 2, wherein the address data of the mobile device are automatically transferred to the portable visual terminal when the mobile device and the portable visual terminal are connected.

5. A discrete type portable visual terminal system as claimed in claim 1, wherein the address data of the mobile device are automatically transferred to the portable visual terminal when the address data of the mobile device are renewed.

6. A discrete type portable visual terminal system as claimed in claim 2, wherein the address data of the mobile device are automatically transferred to the portable visual terminal when the address data of the mobile device are renewed.

7. A discrete type portable visual terminal system as claimed in claim 1, wherein each of the mobile device and the portable visual terminal is provided with an address data input means, and address data are mutually transferred to complement each other'"'"'s address file when the mobile device and the portable visual terminal are connected.
