SUMMARY OF THE INVENTION In the above-mentioned conventional vehicle-mounted mobile telephone, it is necessary to operate the call button at the start of a call even when the mobile phone is taken out from the charger, and the call-end button at the time of call termination is used. Needed operation. On the other hand, when making a call with the mobile phone placed in the charger, in addition to the above-mentioned operation of the call button and end call button, a hands-free connection operation (pressing the hands-free button) or connection of an earphone / microphone There was a problem that the operation had to be performed and the operation was complicated.

An object of the present invention is to eliminate the above-mentioned problems of the prior art, and to carry out a call / end call with a simple operation even when the mobile phone is placed on the charger or taken up. To provide.

[0007]

In order to achieve the above object, the present invention provides a charger, a microphone / receiver for inputting / outputting voice of a mobile phone body, and a voice input when the mobile phone is used separately. External voice input / output means for outputting, transmission means for wireless transmission / reception and voice processing, switching means, detecting means for detecting whether the mobile phone is placed in a charger, and the mobile phone by the detecting means. When it is determined that the portable telephone is not placed, the switching means is controlled so as to connect the external voice input / output means to the transmitting means, and the microphone is determined when the detecting means determines that the mobile phone is not placed. .A mobile phone having a control means for controlling the switching means so as to connect the receiver and the transmission means. It discloses a mobile telephone for mounting.

Further, according to the present invention, when the control means determines that the mobile phone is taken out of the charger when the communication means is not in the call state, the transmission means is set to the call state, and the mobile phone is further activated. A function of controlling the transmission means to be in the call termination state when the detection means determines that the mobile telephone is placed on the charger when the telephone is taken out of the charger and in a call state. An in-vehicle mobile phone having the above-mentioned features is disclosed.

[0009]

Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing a configuration example of an in-vehicle mobile phone according to the present invention, in which a mobile phone (handset) 1 is placed on a charger (in-vehicle device) 2, and a battery 11 is charged by a charger 2. 2 shows a state in which the charging power source 21 of FIG. Further, at this time, the power of each circuit of the mobile phone is supplied from the power source 22 for the main body of the charger (power source from the automobile battery).

The mobile phone 1 includes a wireless unit 12 for performing wireless communication, an audio processing unit 13 for performing processing such as amplification of an audio signal, a microphone / receiver 14, a hands-free 15, a power switch 16, a jack 17, and In addition to the power source 11 described above, a control unit 18, a changeover switch 19, and a switch 23, which are features of the present invention, are provided. The switch 23 is turned off when the mobile phone 1 is placed on the charger 2. It is a mechanical switch that turns on when it is ejected.

In the on-vehicle mobile phone set forth above, the mobile phone 1 is now placed on the charger 2, and the switch 23
Is turned off. At this time, the control unit 18 detects that the switch 23 is turned off, and controls the changeover switch 19 so that the voice processing unit 13 is connected to the hands-free 15 and the jack 17 side. As a result, by pressing a call button (not shown), it is possible to make a call via hands-free without performing a hands-free connection operation or the like. However, earphone / microphone jack 1
The operation of connecting to 7 is the same as the conventional one.

When the mobile phone 1 is placed on the charger 2,
When removed from the charger 2 to start a call, the switch 23 turns on. The control unit 18 uses this switch 23
When it detects that the power has changed from off to on, the wireless unit 1
2 is controlled so that even if the call button is not pressed, the same call state as when the call button is automatically pressed is set. As a result, when the mobile phone 1 is taken out of the charger 2, a call can be started without operating the call button. When the mobile phone 1 is placed on the charger 2 after the call is finished, the switch 23 is turned off, which causes the control unit 18 to perform the same control on the wireless unit 12 as when the end call button is pressed, and the end. The call is released even if the talk button is not pressed. In this way, the operation when making a call or ending a call near the charger 2 can be simplified.

Also, when a call is started with the charger 2 left and the mobile phone 1 is taken out during the call, the switch 23 also changes from off to on, and the voice input / output is hands-free 15. The earphone / microphone is automatically switched to the microphone / receiver 14.
On the contrary, when the mobile phone 1 is taken out from the charger 2 and placed on the charger 2 during a call, the switch 23 changes from on to off, which means that the end button is pressed as described above. Same operation as.

As described above, the switch 23 for detecting whether or not the mobile phone is placed in the charger is provided, and the switching of the voice system and the control equivalent to the operation of the call button and the end call button are performed according to the state. By doing so, the usability of the in-vehicle mobile phone can be greatly improved. In the configuration of FIG. 1, the hands-free 15 and the jack 17 are provided in the mobile phone 1, but it goes without saying that they can be provided on the charger side.

The switch 23 for detecting whether or not the mobile phone is placed on the charger is a mechanical switch. However, a component using a mechanically movable mechanism is used especially for a portable device. May be a problem in terms of reliability and cost. In this case, various well-known techniques such as an electrical contact, an optical switch, or a detection mechanism by electromagnetic action may be used instead of the mechanical switch.

[0016]

According to the present invention, a call can be made and a call can be made only by removing the mobile phone from the charger, and conversely, the call can be ended simply by placing the mobile phone on the mobile phone for vehicle in a talking state. Furthermore, the voice system can be automatically switched between when the mobile phone is placed in the charger and when it is taken out, which also has the effect of simplifying the operation.
