A power supply circuit 28 for supplying each part in the handset 11 and each part in the cradle 12 and a power supply control circuit 29 for controlling power supply from the power supply circuit 28 to each part based on a command from the handset controller 26. Have. Note that power is supplied directly to the handset controller 26 and the wireless device controller 31 from the power supply circuit 28 without passing through the power supply control circuit 29.
[0016]
The wireless device 13 includes a transceiver 30 for transmitting and receiving voice by a predetermined modulation method, and a wireless device controller 31 for exchanging signals with the transceiver 30, the handset controller 26, an external device connected to the connector 15, and the like. . The wireless device controller 31 includes a known CPU, ROM, RAM, and the like.
[0017]
The card 14 employs a SIM (Subscriber Identity Module) card which is an IC card in the present embodiment. In the memory composed of the EEPROM, PIN data for identifying itself, telephone directory data of a telephone number, abbreviated number, and registered name of a called party registered in a memory dial, and setting of a ringtone sound pattern And various setting data such as setting of a key operation confirmation sound that sounds at the time of key operation.
[0018]
The connector 15 connects the wireless device controller 31 of the wireless device 13 to an external device. In the present embodiment, a multi-TV system 32 is connected as the external device.
The multi-TV system 32 includes a telephone unit 35 for outputting an audio signal to an acoustic speaker 33 for outputting an audio CD, television sound, and the like, and for inputting an audio signal from an in-vehicle microphone 34 for picking up the in-vehicle sound. And a media device 36 other than the telephone unit 35 (for example, a navigation unit), a display 37 with a touch switch that switches when the screen is touched with a finger (corresponding to the on-vehicle input means of the present invention), and A multi-TV controller 38 for controlling and exchanging signals with the wireless device controller 31 via the connector 15 is provided. The multi-TV controller 38 includes a well-known CPU, ROM, RAM, and the like. When a power switch (not shown) of the multi-TV system 32 is turned on, power is supplied from the battery BT.
[0019]
Next, the operation of the present embodiment configured as described above will be described.
When an ignition switch (not shown) of the vehicle is operated, the voltage from the battery BT is supplied to the handset controller 26 and the wireless device controller 31 via the power supply circuit 28. Then, the handset controller 26 executes the mode setting process shown in FIG. 3 at predetermined time intervals (every several ms).
[0020]
When this process is started, the handset controller 26 determines whether or not the card 14 is inserted into a slot (not shown) of the handset 11 in a first step (hereinafter referred to as S) 110. This determination is made based on an output signal from a card detection sensor such as an optical sensor provided in the slot. If the card 14 is not inserted into the slot at S110 (NO at S110), a mode relating to card use in the RAM of the handset controller 26 (here, "card use permission mode" for permitting card use, or The area for storing the "card use prohibition mode" for prohibiting card use is reset (S115), and this process ends. Therefore, once the inserted card 14 is removed, the mode relating to card use is reset. On the other hand, if the card 14 is inserted in the slot in S110 (YES in S110), the process proceeds to S120.
[0021]
When the card 14 is not inserted into the slot, the display 21 of the handset 11 is displayed on the display unit 21 of the handset 11 (when the telephone unit 35 is selected while the multi-TV system 32 is turned on, the display 37 with a touch switch is also displayed). ), A message prompting the user to insert a card, for example, "Please insert a card" may be displayed, and then the processing may be terminated. When the card 14 is inserted into the slot, the message may be erased.
[0022]
By the way, in the subsequent S120, the handset controller 26 has already stored any one of the "card use permission mode" and the "card use prohibition mode" in the area for storing the card use mode in the RAM of the handset controller 26. It is determined whether or not it is (S120). If any mode has already been stored in this area (YES in S120), this process ends as it is already determined whether the currently inserted card 14 can be used. On the other hand, if this area has been reset (NO in S120), it is determined in subsequent S130 whether a PIN has been input from the operation unit 22 of the handset 11 or the display 37 with a touch switch of the multi-TV system 32. . The case where the PIN is input from the display 37 with the touch switch corresponds to the case where the multi-TV system 32 is powered on and the telephone unit 35 is selected. When the PIN is input from the display with the touch switch, the PIN is transmitted to the handset controller 26 via the multi-TV controller 38 and the wireless device controller 31.
[0023]
In subsequent S130, if no PIN has been input from any of them (NO in S130), handset controller 26 ends this processing. On the other hand, if the PIN has been input from any of them in S130 (YES in S130), the process proceeds to S140. When the PIN is not input, the PIN input is displayed on the display unit 21 of the handset 11 (and also on the display 37 with a touch switch when the telephone unit 35 is selected with the multi-TV system 32 turned on). For example, a message prompting "Please enter your password" may be displayed, and this message may be deleted when the PIN is entered.
[0024]
In subsequent S140, the PIN stored in the card 14 is read, and it is checked whether the read PIN matches the PIN input from the operation unit 22 of the handset 11 or the display 37 with the touch switch of the multi-TV system 32. I do. Then, in the subsequent S150, if the two do not match as a result of the PIN verification (NO in S150), the "card use prohibition mode" is set in the area for storing the card use mode of the RAM of the handset controller 26 ( S160), this process ends. On the other hand, if both match in S150 (YES in S150), it is determined that the registrant of the telephone number stored in card 14 or a person who has received a license from the registrant uses this card-mounted car telephone device. Then, the "card use permission mode" is set in the area for storing the above-mentioned card use mode (S170), and this process ends.
[0025]
Since the area for storing the mode relating to the card use is a part of the RAM, the mode is reset when the power is not supplied to the handset controller 26 (for example, when the key is removed from the key cylinder of the automobile).
By the way, before executing the normal operation, the handset controller 26 reads out the contents of the area for storing the card use mode and checks the mode. If the read mode is the "card use permission mode", the normal operation is performed. Specifically, in response to an input signal from the operation unit 22 of the handset 11 or an input signal from the display 37 with a touch switch of the multi-TV system 32, a normal operation as a telephone is executed, and the card I / F 23 is appropriately connected. To access the card 14. On the other hand, when the read mode is the “card use prohibition mode”, the display unit 21 of the handset 11 is provided with a touch switch when the telephone unit 35 is selected while the multi-TV system 32 is powered on. On the display 37), a message indicating that the card 14 cannot be used is displayed, for example, "Card cannot be used", and the normal operation is not executed.
[0026]
Here, the normal operation refers to various control processes for realizing a function as a general telephone device. For example, (1) another communication with the telephone network via the transceiver 30 of the wireless device 13 is performed. A calling process for transmitting a calling signal for calling a telephone device; (2) when a calling signal is transmitted from the base station, a ring tone is generated from the speaker 27 of the cradle 12 in accordance with the ringing pattern stored in the card 14. (3) connection processing for connecting the mobile telephone device 10 to the telephone network when the user inputs a command to connect the mobile telephone device 10 to the telephone network by generating a ring tone; ▼ When the called telephone device is connected to the telephone network by calling processing, and the telephone with the telephone device of the called party becomes available, or the connection processing connects the car telephone device 10 to the telephone network. Been When a call with the telephone device on the caller side becomes possible, a signal input by the user from the microphone 25 of the handset 11 is transmitted to the base station side, and a voice signal transmitted from the telephone line network is transmitted to the handset 11. The voice input / output processing to be output from the speaker 24 of (5), the sounding pattern updating processing for storing the updated contents in the card 14 when the sounding pattern of the ringing tone is updated, and (6) the answering machine function Answering message processing for storing the message message obtained when the card is set on the card 14 and playing back the message message stored on the card 14, (7) Touching the operation unit 22 of the handset 11 or the multi-TV system 32 Based on the speed dial or registered name input from the display 37 with the switch, the corresponding telephone number is obtained from the telephone directory data stored in the card 14. Speed-dial call processing to call out look, ▲ 8 ▼ telephone directory telephone directory data update process of storing the updates to the card 14 in the case of performing the update operation of the data, such as is exemplified.
[0027]

And the operability is excellent.
[0028]
Further, in the present embodiment, since at least a telephone number is stored as personal information in the card 14, if a third party uses the card without permission of the card holder, the telephone number may be known without the card owner's knowledge. There is an inconvenience that the registrant of the number (often the same as the cardholder) is charged. For this reason, in particular, it is necessary to increase security, and it is highly necessary to perform PIN collation. At the same time, there is a high demand that the card 14 can be used only by operating the display 37 with the touch switch of the multi-TV system 32. The above effects are effectively exhibited.
[0029]
