Portable information terminal
First Claim
1. A portable information terminal comprising:
- a primary terminal having a memory member for storing application programs and data, and a communication member for transmitting and receiving the application program and the data; and
a secondary terminal having a communication member for transmitting and receiving the application program and the data to and from said communication member of said primary terminal, a memory member for storing the application programs and the data transmitted to and received from said primary terminal, and a control member for controlling operation of the communication member and the memory member of the secondary terminal, wherein said communication member of said secondary terminal and said communication member of said primary terminal are communicated under control of said control member for transmission of the application programs and data retained in said memory member of said primary terminal to said secondary terminal, and then the transmitted application programs and data are stored in said memory member of the secondary terminal to form functions installed on the secondary terminal, and wherein said communication member of said secondary terminal and said communication member of said primary terminal are communicated under control of said control member for transmission of the data accumulated on said secondary terminal as a result of execution of the application program installed on the secondary terminal, to said primary terminal, and then the transmitted data is stored in said memory member of the primary terminal.

Abstract
A portable information terminal includes a main terminal 2 having a RAM 24 and a communication circuit 27, and a secondary terminal 3 having a communication circuit 38, a RAM 36 and a CPU 30. The communication circuit 38 of the secondary terminal 3 and the communication circuit 27 of the primary terminal 2 are communicated under control of the CPU 30, for transmission of application programs and data stored in the RAM 24 of the primary terminal 2, to the secondary terminal 3. Then the transmitted application program and data are stored in the RAM 36 of the secondary terminal 3 to form functions to be installed in the secondary terminal 3. The secondary terminal 3 is communicated with the communication circuit 27 of the primary terminal 2 to transmit data accumulated on the secondary terminal 3, to the primary terminal 2. Then the transmitted data is stored in the RAM 24 of the primary terminal 2.
