FIG. 2 shows a schematic structure of a back surface (a), a side surface (b) and a front surface (c) of the mobile phone 100 of FIG. 1 when the present invention is applied to a stick type mobile phone. . As can be seen from this figure, the mobile phone 1
On the front side of 00, the display unit 6, the operation unit 7, the LED unit 14,
A microphone 15 and an ear receiver 16 are arranged. On the back side of the mobile phone 100, the IC card module 30) is arranged behind the display unit 6 and the battery 31 is arranged behind the operation unit 7. Further, in the illustrated example, a rear speaker (or buzzer) 36 is arranged between the IC card module 30 and the battery 31. These positional relationships do not necessarily have to be the same as illustrated.
Importantly, the IC card module 30 (at least the antenna 11 of the IC card module 30) is located near the back surface of the mobile phone 100, and the LED portion 1 as a visual output means is provided on the front surface side.

It is desirable to be implemented. In addition to the above, it is also possible to use a device in which an operation button (operation key) of the operation unit is illuminated.

FIG. 6 is a flowchart showing the interaction between the IC card unit 20 and the control unit 5 when the IC card of the mobile phone 100 is used. When the user holds the mobile phone 100 over the external R / W 41, the IC card unit 20 detects the polling signal from the external R / W 41 (S1).
1). At this time, the IC card unit 20 performs connection authentication with the external R / W 41, and if the authentication is OK (S12, Y
es), card-based communication according to the service to be used is performed with the external R / W 41 (S13). Then IC
The card unit 20 transmits a notification signal indicating that the card has been normally used to the control unit 5 (S14). The control unit 5 receives this notification signal (S21) and generates a notification output in a predetermined output mode by one or more of the various output means described above (S22). Note that step S13
The execution order of steps S14 and S14 may be reversed.

When it is held up to 41, the IC card unit 20
The polling signal from 1 is detected (S31). At this time, the IC card unit 20 authenticates the connection with the external R / W 41, and if the authentication is OK (S32, Yes), receives the application ID for identifying the application from the external R / W 41 ( S33). Then,
Card utilization communication is performed with the external R / W 41 according to the service to be used (S34). After that, the IC card unit 20 transmits a notification signal indicating that the card has been normally used to the control unit 5 (S35). The control unit 5 receives the notification signal together with the application ID (S41), and generates a notification output in a predetermined output mode by the output means that is predetermined according to the application ID (S42).
The execution order of steps S34 and S35 may be reversed.

In the present embodiment, the point different from the above configuration is that the non-contact IC card module 30 is also provided with the LED 25.
The LED 25 is controlled by the non-contact IC card unit 20 regardless of the control unit 5. However, operating power is obtained from the power supply unit 9. By doing this, when the mobile phone with the built-in IC card does not operate as expected, it becomes easier to isolate the cause of the failure, whether it is the mobile terminal side or the IC card side, and the failure occurs. It can contribute to shortening analysis time and improving repairability. It should be noted that the LED unit is mounted on the module as the most practical means here because it is inexpensive and easy to implement, but the present invention is not limited to this, and the audio output unit shown in FIG. , A display unit, a vibrator unit, and the like may be mounted.
