The information stored in the IC card 1 includes information unique to the card for identifying each card and data on transmission restriction to the user of the card.

Next, in step 103, the personal computer 4 determines whether or not the card is restricted from being transmitted based on the card-specific information transmitted from the main device 3, and the card is restricted. If so, the fact is transmitted to the IC card 1 and stored (step 104). If no restriction is imposed, it is determined whether or not there has been an outside line capture request (step 106).
If there is no outside line capture request, it is determined whether or not the IC card 1 is inserted into the telephone 2 (step 109). If there is, the process proceeds to the code (FIG. 5).

On the other hand, if there is an outside line capture request in step 105, it is determined that the dial has been pressed (step 106). When the dial is pressed, the pressed dial number is transmitted to the main unit 3 (step 108). Move to (FIG. 5). If it is not pressed, it is determined whether or not there is an outside line release request (step 107). If not, the process returns to step 106, and if there is, the process proceeds to step 109.

Next, in step 110, when a signal is sent from the main unit 3 that the dial number pressed in step 108 is a restriction number,
Move to 14. If it is not the restriction number, a call process is performed (step 111), and it is determined whether or not the call has ended (step 112). If the call has ended, the process proceeds to step 113, where the current call time and the dial number of the call destination are set. Is transmitted to the personal computer 4. Then step 1
At 14, it is determined whether or not the IC card 1 is inserted into the telephone 2, and if not, a signal indicating that the IC card 1 has been removed is transmitted to the main device 3.

When the information is transmitted, it is determined whether or not the information includes data on the regulation number (step 20).
2). If so, the data relating to the regulation number is registered in the memory in the main device 3 and transmitted to the personal computer 4 (step 203).

Next, in step 204, the main unit 3 determines whether or not a regulation number has been input from the personal computer 4 to the above-mentioned new card (step 204).
When input, the data relating to the regulation number is registered in the main device 3 (step 205), and is also notified to the telephone 2 (step 206).

Next, in step 207, it is determined whether or not a signal for capturing an outside line has been received. If not, it is determined whether or not a signal indicating that the IC card 1 has been removed has been received from the telephone 2 ( Step 219),
If it is received, it shifts to the code, and if it is not received, it shifts to the code.

On the other hand, when the signal for capturing the outside line is received in step 207, the process waits until all the dials pressed by the telephone 2 are received (step 208). Transition. When all the dials have been received, it is determined whether the received number is a regulation number (step 209). If it is regulated, the fact that the calling number is regulated is output to the telephone 2, and the outside line is opened (step 211).
Thereafter, when a signal indicating that the IC card 1 has been removed is received (step 212), a signal indicating that the IC card 1 has been removed is transmitted to the personal computer 4 (step 213).

On the other hand, if the number received in step 209 is not a regulation number, a call process is performed (step 21).
5) Wait until the call ends (step 216), and after the call ends, release the outside line (step 217) and output the call information to the personal computer 4 (step 218). However, in step 220, it is always determined whether or not the IC card 1 has been removed before the call ends, and if it has been removed, it is determined whether or not data call information has been received from the telephone 2 (step 2).
21) When received, the call information is output to the personal computer 4 (step 222). If no call information is received in step 221, the telephone 2 is requested to transmit the call information (step 223).

Next, the operation of the personal computer will be described. FIG. 8 is a flowchart showing the operation on the personal computer side. FIG. 9 is a flowchart showing a step subsequent to that of FIG.
