Abstract

A mobile device is provided. The mobile device provides simple connection with a mobile device unit, resistant to noise from the mobile device unit, and enabling a GPS function to be fully exhibited, wherein a first integrated circuit IC21 mounting a GPS receiver and GPS antenna and a second integrated circuit IC22 mounting a controller control circuit are housed in a controller unit, the controller unit is provided with a headphone jack and a music/speech terminal-GPS terminal to be connected to the mobile device, and the terminal is inserted into the mobile device unit to supply power source voltage from the mobile device unit side and enable the controller and GPS function to be used.

Claims

1. A mobile device comprising:

a mobile device unit for performing predetermined processing in accordance with an operation from an outside, and

a remote controller unit for operating said mobile device unit from the outside, said mobile device unit including

a power circuit capable of supplying drive power for said remote controller unit and

a first control circuit for controlling processing in accordance with information of said operation from the outside,

said remote controller unit including

connecting means having at least an information line and a power line and capable of connecting to said mobile device unit,

at least one operating means for operating said mobile device unit,

a position-finding receiver receiving drive power through said connecting means from said mobile device unit and receiving a satellite signal capable of obtaining position-finding information, and

a second control circuit providing at least position information corresponding to the position-finding information of said position-finding receiver through said connecting means to said first control circuit of said mobile device unit.

2. A mobile device as set forth in claim 1, wherein

said remote controller unit comprises a power line for transmitting power voltage supplied through said connecting means and a signal line connected to an information line of said connecting means, and

said operating means is connected between said power line and said signal line.

3. A mobile device as set forth in claim 1, wherein said remote controller unit comprises a power switch for turning said supplied power on or off at a line supplying the second control circuit and position-finding receiver with drive power supplied through said connecting means.

4. A mobile device as set forth in claim 1, wherein said second control circuit is capable of controlling said mobile device unit through said connecting means where said position-finding receiver is optionally used and provides position information through said connecting means to said first control circuit of said mobile device unit when said position-finding receiver is being used.

5. A mobile device as set forth in claim 4, wherein

said remote controller unit comprises a headphone jack, and

said connecting means includes a music/speech terminal for supplying music/speech information to said headphone jack.

6. A mobile device as set forth in claim 4, wherein said connecting means includes a shared terminal for a control line of said mobile device unit and a transfer line of said position information of said second control circuit.

7. A mobile device as set forth in claim 5, wherein said connecting means includes a first terminal including a control line of said mobile device unit and a music/speech line and a second terminal including a transfer line of said position information of said second control circuit.

8. A mobile device as set forth in claim 1, wherein

said remote controller unit comprises a display device, and

said second control circuit controls the display of said display device.

9. A mobile device as set forth in claim 1, wherein the first control circuit of said mobile device unit is capable of setting an update time of position information at said second control circuit through said connecting means.

10. A mobile device as set forth in claim 1, wherein the first control circuit of said mobile device unit controls said second control circuit to set said position-finding receiver in a sleep mode or an operating state through said connecting means.

11. A mobile device as set forth in claim 3, wherein the first control circuit of said mobile device unit controls said second control circuit to set said position-finding receiver in a sleep mode or an operating state through said connecting means.

12. A mobile device as set forth in claim 1, wherein said second control circuit sets said position-finding receiver to a sleep mode when no operating means is operated for a predetermined time and starts up said position-finding receiver when the operating means is operated.
