The audio data (analog signal) input from the microphone 6 is converted into a digital signal by the audio encoding unit 5 and connected to the modulation of the transmission unit 2. The digital signal from the receiving unit 1 is converted into analog signal audio data by the audio decoding unit 7 and supplied to the receiver 8.

The display unit 9 and the operation unit 10 constitute an interactive input device, and dial information / function settings input from the operation unit 10 are displayed on the display unit 9 constituted by an LCD (liquid crystal display) or the like. Entered after confirmation from the operator.
The display unit 9 also displays the reception state of the radio wave of the wireless telephone, the power ON / OFF state, and other various setting states.
The storage unit 11 stores a message required when the wireless telephone operates in the automatic call answering mode. In addition, in the embodiment illustrated in FIG. 1, it is considered that a program and data for operating the control unit 3 are also stored in the storage unit. An incoming call mode flag indicating whether the wireless telephone is in the normal incoming call mode or the automatic incoming call answering mode is also provided in the storage unit 11.

The incoming call mode flag, reed switch 12, magnet 13, and in-vehicle holder 14 in the storage unit 11 are parts specially provided in the portable radio telephone which can be mounted on the car according to the present invention. Is a flag (flag) for storing a detection result of whether the mobile device is in the mobile state or in the vehicle state. When there is an incoming call to this wireless telephone,
If the flag is set, the control unit 3 controls the wireless telephone in the automatic incoming call answering mode. If the flag is reset, the control unit 3 controls the wireless telephone in the normal incoming call mode.

The reed switch 12 and the magnet 13 are detecting means for detecting whether the wireless telephone is in a portable state or in a vehicle-mounted state. The reed switch 12 is positioned near the magnet 13 in the mounted state, and the contact of the reed switch is closed by the influence of the magnetic field of the magnet 13 to set the incoming call mode flag to the set state.

When the wireless telephone is used in a portable state, the contact of the reed switch 12 is open, the incoming call mode flag is in a reset state, and the control unit 3 controls the wireless telephone in the normal incoming call mode. The operation in the normal incoming call mode is well known in the related art, but will be briefly described below for comparison with the operation in the automatic incoming call answering mode. A communication signal from the base station is transmitted by a control channel (frequency for transmitting a communication signal) and received by the receiver 1. The control unit 3 controls the receiving unit 1 to determine the frequency of the control channel that the receiving unit 1 should wait for.
Performs a channel scan, selects a control channel that satisfies the standby condition, and sets a standby state on that channel. In the standby state of the normal incoming call mode, the reception state of the radio wave and the power on / off state are displayed on the display unit 9.
The off state and other various setting states are always displayed.

When a call arrives at the radio telephone, a message such as the telephone number (call number) and call setting information of the telephone is transmitted from the radio base station as paging information on a control channel, and received by the receiver 1. Is done. The control unit 3 detects the paging information and compares the call number with the own number set in the ROM in the storage unit 11 (this part of the ROM may be considered to exist in the control unit 3). If they match, the paging information is determined to be an incoming call addressed to the own station, and the sounder 4 sounds to notify the incoming call state. At the same time, transmission / reception of call control according to a call connection procedure is performed via the transmission unit 2 and the reception unit 1, and a response signal is transmitted to the radio base station by a response operation of a user input from the operation unit 10. Capture.

When the portable radio telephone is mounted on an automobile, the radio telephone is mounted on the vehicle-mounted holder 14, and

When the contact of the reed switch 12 is closed, the incoming call mode flag in the storage unit 11 is set, and it is set that the incoming call should be controlled in the automatic incoming call answering mode. When entering the standby state from the channel scan, the control unit 3 checks the state of the incoming call mode flag, and when in the set state, reads out a control program in the automatic incoming call answering mode and performs control. In the control in the automatic incoming call answering mode, all the display on the display unit 9 is erased, and the input from the operation unit 10 is not accepted, so that the mobile wireless telephone is locked. Turn off. However, even in this state,
The receiving unit 1, the transmitting unit 2, and the control unit 3 operate normally, and operate in the same manner as in the standby state in the normal incoming call mode until the incoming call.

When there is an incoming call, the control unit 3 detects the paging information, compares the call number with the own station number stored in the ROM in the storage unit 11, and, if the comparisons match, sends the call to the own station. And performs control similar to that of an answering machine. That is, the call connection procedure via the transmitting unit 2 and the receiving unit 1 is performed without ringing the ringing sound (sound for notifying the user of the incoming call) by the sounder 4 and without waiting for a response operation from the operation unit 10. , Automatically captures the call line, transmits a message previously stored in the storage unit 11 to the caller, and writes a message from the caller to the storage unit 11. At this time, the message from the caller written in the storage unit 11 can be read out by performing a predetermined operation from the operation unit 10 with the wireless telephone set in a portable state. As described above, in the automatic call answering mode, the user does not need to perform any operation on the wireless telephone, so that the safety of driving the vehicle is not reduced by the presence of the wireless telephone.
