DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device in which a display is provided on a foldable device main body.

[0002]

As the navigation device, there are a navigation device used by pedestrians and a navigation device mounted on a vehicle. Recently, a navigation device that can be used for both of them is considered. ing. In this case, when used as a car navigation device, the display device needs to have a certain size and the device itself becomes large, but it is necessary to avoid that it is too large when a pedestrian carries it.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object the advantage of being compact and easy to use when carried, and also capable of being conveniently used as a display means of a car navigation device. To provide a navigation device.

[0004]

To achieve the above object, the means described in claim 1 can be adopted. According to this means, since the apparatus main body can be folded, the apparatus can be compact when carried. Since the display means is provided in the plurality of main units, a wide display area can be secured by expanding the plurality of main units when the vehicle is mounted on a vehicle. Also, a wide display area can be ensured even when the mobile phone is carried.

In this case, according to the second aspect of the present invention, a map is displayed on a color display suitable for displaying a pattern or a figure, and characters are displayed on a monochrome display having a high contrast. This makes it easy to use the map, making it easier to see the map and characters. According to the third aspect of the present invention, the touch panel switch slightly reduces the transparency of the display. However, since the touch panel switch is formed on a monochrome display having a high contrast, the transparency is reduced despite the provision of the touch panel switch. Influence can be reduced.

On the entire surface of the monochrome LCD panel 6, a matrix type touch panel switch (indicated by reference numeral 14 in FIG. 2) is formed. A color LCD panel (corresponding to a display means, a color display) is provided on the other main body 3.
7 are provided.

The main body 3 of the portable terminal main body 2 is provided with a power switch 8 for turning on / off the power in a hardware manner. Further, on the side of the main body 3, a connection terminal 9 is provided as a connection for obtaining map data and the like from the outside.

FIG. 2 is a block diagram showing an electric configuration of the portable terminal 1, and the portable terminal 1 includes a CPU serving as control means.
10, a GPS receiver 11 as position detecting means, and R
A memory 12 having an OM and a RAM, a speaker 13 as an audio output unit, and the touch panel switch 1
4, the monochrome LCD panel 6, and the color LC
It has a D panel 7 and a communication interface 15, and the connection terminal 9 is connected to the communication interface 15. A mobile phone 16 is connected to the connection terminal 9, and map data information is acquired through an Internet connection by the mobile phone 16.

The GPS receiver 11 is configured to detect the current position of the portable terminal 1. The ROM of the memory 14 stores a navigation program,
The RAM temporarily stores temporary data at the time of program execution, map data acquired from the outside, and the like.

[0010] The car navigation body 17 is a car 1
8 (see FIG. 4), and its electrical configuration is
As shown in FIG. 6, a CPU 19, a position detector 20, R
A memory 21 having an OM and a RAM, a speaker 22 as an audio output unit, an operation switch group 23, a map data memory 24 as a map data supply unit, for example, a CDROM, and a portable terminal interface 25. The portable terminal interface 25
Is connected to a connection terminal 26.

The position detector 20 includes a geomagnetic sensor 2
7. Gyroscope 28, distance sensor 29 and GP
It comprises an S receiver 30, and detects the current position of the vehicle. As shown in FIGS. 4 and 5, a dashboard 31 of the car 18 is provided with a holder 31 for holding the mobile terminal 1 in an open state at a certain angle. The connection terminal 26 is provided, and when the portable terminal 1 is set on the holder 31, that is, when the portable terminal 1 is set on the car 18, the connection terminal 9 of the portable terminal 1 is connected to the connection terminal 26. It has become. And in this set state,
The car navigation body 17 and the LCD panels 6 and 7 constitute a car navigation device.

Next, the operation of the above configuration will be described. When the portable terminal 1 is used as a pedestrian navigation device (portable navigation device), the connection code 32 is connected to the connection terminal 9 of the portable terminal 1 as shown in FIG.
The mobile phone 16 is connected via the. The electrical configuration at this time is as shown in FIG. And the power switch 8
Is turned on, an operation menu, an arrow for scrolling, and the like are displayed on the monochrome LCD panel 6. When the touch panel switch 14 of the menu portion or the arrow portion is pressed, control corresponding to the menu or the arrow is executed. It has become. For example, if you set a destination, GPS
The current position is acquired from the receiver 11, and a route from the current position to the destination is set and controlled, and a map is displayed on the color LCD panel 7, and an arrow indicating a direction in which the pedestrian should travel is displayed. .

When the portable terminal 1 is used as a car navigation device, the portable terminal 1 is set on the holder 31 as shown in FIGS. Then, the connection terminal 9 of the mobile terminal 1 is connected to the connection terminal 26.
(See FIG. 6). In this case, on the car navigation body 17 side, based on the operation of the operation switches 23, the destination setting and the route setting are not performed, and the current position is acquired by the position detector 20.
The map data is read from. Then, from the car navigation body 17 side, the monochrome LC of the mobile terminal 1 is displayed.
A display command for the D panel 6 and the color LCD panel 7 is output, and the portable terminal 1 displays characters on the monochrome LCD panel 6 as shown in FIG.
