It is a device that can communicate with the outside without a telephone, and its use is expected to expand in the future.

[0003] In addition, even in an automobile in which the above-mentioned hands-free device is not installed, the mounting area of the radio telephone is determined in advance at a predetermined position around the driver's seat, and the driver receives an incoming call while driving. It is worthwhile not to have to hunt around for a wireless telephone.

Under such circumstances, for example, as shown in FIG.
A method in which a mounting table (cradle) 1 for mounting a wireless telephone is formed at a fixed position such as a box cover upper surface of a console box in an automobile, and a wireless telephone 2 is mounted on the mounting table 1. Has been proposed. FIG. 6 is a diagram showing a state in which the hands-free device is installed in the vehicle. Here, an amplifier for amplifying a reception signal or a transmission signal of the wireless telephone is built in the mounting table 1, a microphone device 3 is mounted on a corner of the sun visor 4, and a speaker device 5 is mounted on a foot side wall of the seat. Have been. And
The driver can perform call communication without holding the wireless telephone 2 when waiting for a signal, temporarily stopping, or the like.

[0005]

Here, when the radio telephone 2 is mounted on the mounting table 1 which is a fixed position as described above, when the driver or the like finishes driving and gets off the vehicle, In some cases, the wireless telephone 2 may be inadvertently left on the mounting table 1. Therefore, it is desirable to notify the driver or the like of such misplacement of the wireless telephone 2 by some method.

[0006] In general, as a device for preventing the radio telephone 2 from being left inside the vehicle, for example, Japanese Patent Application Laid-Open Nos. 8-265850, 8-265851, 8-265.
No. 855, Japanese Utility Model Application Laid-Open No. 5-80047 or Japanese Utility Model Application Laid-Open No. 6-73936, as shown in FIG. 7, a radio wave emitted from a transmitter built in the wireless telephone 2 is carried by a driver or the like. When the receiver 6 captures and leaves the wireless telephone 2 in the car, the wireless telephone 2 and the portable receiver 6
A method is disclosed in which a warning is issued when both are separated by a distance L or more that is set in advance, thereby notifying that the wireless telephone 2 has been left behind.

[0007] These methods have an advantage that even if the radio telephone 2 is not placed in a fixed position in a car, the radio telephone 2 can be informed that the radio telephone 2 has been left behind. However, due to its configuration, the portable telephone 2 is provided separately from the radio telephone 2. It is necessary to have the receiver 6.

[0008] Further, since the misplacement is notified only when the portable receiver 6 is at least a predetermined distance L or more, the portable receiver 6 must notify the misplacement and return to the car. However, it takes much time to return to the car. In some cases, it may be necessary to give up to return to pick up the wireless telephone 2 in a hurry or the like.

In addition, if the vehicle is parked in a place such as a multi-story parking lot where once it enters the car, it cannot return to the car until the car leaves, even if the portable receiver 6 informs the user that the car has been left behind, the car is moved to the next place. Until leaving, wireless telephone 2
