BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for mainly displaying information for a navigation system, and more particularly to a portable or in-vehicle use, and to a use other than a navigation system. To a display device that can be used.

[0002]

2. Description of the Related Art A navigation system for displaying a current position and a traveling position of a moving object on map information or the like has been developed mainly for mounting on a car. In this in-vehicle navigation system, a display member having a display surface such as a color liquid crystal panel is fixed to a dedicated support leg that stands up from the floor of an automobile, or
In general, a display member projects upward from a housing embedded in a console panel of an automobile, rotates upward, and a screen is directed to a vehicle interior. Further, an antenna for detecting the current position and the traveling direction of the vehicle is fixed to an upper surface of the roof of the vehicle.

[0003]

In the above-mentioned conventional car navigation system, an antenna is installed on the roof top or the like. Therefore, when the navigation system is mounted, it is necessary to mount the antenna. Further, a cord connecting the unit provided in the vehicle interior and the antenna must be wired inside the vehicle. For this wiring, it is necessary to remove the lining etc. in the vehicle interior,
The work for this wiring is also complicated. Further, since it is assumed that the display member and the antenna are installed at different places, it is impossible to remove the display member and the antenna from a car and use them as a portable navigation system.

The present invention has been made to solve the above-mentioned conventional problems, and the display member and the antenna can always be used as an integrated state, so that the installation of the antenna and the wiring in the vehicle compartment are not required, and furthermore, it is possible to use the display member and the mobile phone. It is an object of the present invention to provide a display device that can be used for different purposes.

[0005]

A display device according to the present invention has a support attached to a vehicle body, and a monitor screen.
A main body supported by the support so that the monitor screen is in an upright posture when used, a closed position covering the monitor screen, and an open position allowing the monitor screen in the upright posture to be visible. When the lid is rotatably provided between the main body and the lid is rotated to a position extending substantially vertically from the monitor screen in the open position,
Provided so as to be exposed on a surface facing upward of the lid , and
And an antenna for a navigation system detachable from the lid .

[0006]

[0007]

[0008] Alternatively, the display device according to the present invention comprises a monitor.
Main body with a data screen, and
Between the position covering the monitor screen and the position where the monitor screen appears
And a lid that can be turned and a navigator attached to the lid

Next, a description will be given of an example of use of a display device composed of the above members. FIG. 2 shows a case where the device is used for a vehicle. The members used in this case are the main body 1, the first operation member 20, and the support 40. When used as a navigation system, the lid 10
And the GBS antenna 15 are used. In the case of a vehicle, the main body 1 is mounted on the support portion 41, and the support base 40 is mounted on, for example, the console panel P and in front of the windshield F. The first operation member 20 is used for remote operation, and when the occupant operates the operation member 20, necessary information, for example, reception information as a television receiver is displayed on the monitor screen 2. When used as a navigation system, the lid 10 is provided on the first surface 1.
When the cover 10 is turned downward, the second surface 10b is attached to the main body 1 with the second surface 10b facing the monitor screen 2. By attaching the GBS antenna 15 to the first surface 10a which faces upward in the state of FIG. 2, it becomes possible to receive satellite signal waves and the like from the direction of the windshield F. In addition, since the cover 10 is directed toward the passenger compartment above the monitor screen 2, the cover 10 functions as a sun visor, and external light is applied to the monitor screen 2.
Of the monitor screen 2 can be easily viewed.

Note that the support 40 is not necessarily limited to the one provided on the upper surface of the console panel P. A support or an arm may be provided on the Pa portion of the console panel P or the like, and the support 40 may be provided thereon. . FIG. 3 shows a usage method for obtaining the reception strength of the GBS antenna 15 more reliably. In this case, an antenna case 50 that can be easily attached and detached by a suction cup or a magnet is attached to the upper surface of the roof R of the automobile, and the GBS antenna 15 removed from the concave portion 13 of the lid 10 is attached to the antenna case 50.
Is fitted and mounted in the mounting recessed portion 51. In this case, the cord 52 extending from the antenna case 50 is drawn into the vehicle interior from the upper end of the window glass W, and is connected to the connector 7 of the main body 1.

FIG. 4 shows a case where the display device is used as a portable navigation system.
At this time, when the lid 10 is closed, the first surface 10a
Cover 10 so that is facing the monitor screen 2.
Is attached to the main body 1. Also, the first part on the side of the body 1
Operation member 20 is attached. As a power source, a built-in battery in the main body 1 or the first operation member 20 is used, or an external battery box is used. When stored in a bag or the like, the lid 10 is folded in the direction of the arrow. At this time, since the monitor screen 2 is covered by the cover 10 to protect the color liquid crystal panel, and the GBS antenna 15 is attached so as not to protrude greatly from the first surface 10a of the cover 10, the cover 10 must be closed. G
The BS antenna 15 is also protected.

When used as a navigation system, the lid 10 is opened as shown in FIG. 4 so that the monitor screen 2 can be viewed. At this time, the lid 10
The GBS antenna 15 provided on the first surface 10a is pointed toward the sky, and it becomes easy to receive satellite signal waves and the like.
In FIG. 4, the GBS antenna 15 is detached from the lid 10, or the lid 10 is detached from the main body 1, and a first operating member 20 or a second operating member 30 capable of operating a tuner or an external tuner is used. By doing
It can also be used as a portable television receiver.

Further, the first and second operation members 20 and 30 are attached to the main body 1 and game software is stored in the operation members 20 or 30, so that it can be used as a portable video game machine. Alternatively, it can be used as a karaoke monitor by a similar method. When used as a game console or karaoke monitor,
If the support base 40 is used, it can be used not for portable use but for installation in a vehicle or at home. The antenna is not limited to the GBS antenna, but may be an antenna for receiving a signal wave from another satellite or a detection antenna capable of detecting a position by geomagnetism. The information received by the antenna is not limited to information related to a current position and a traveling direction, which are general for a navigation system, and may be congestion information or other traveling information emitted from a satellite or the like.
