Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device which mainly displays information for a navigation system, and can be applied to various applications such as portable and in-vehicle use, and also used for applications other than the navigation system. Display device that can be used.

[0002]

2. Description of the Related Art A navigation system for displaying the current position and the moving position of a moving body on map information or the like has been developed mainly for mounting on an automobile. 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 is projected from a casing embedded in a console panel of an automobile and rotated upward so that the screen is directed to the interior of the vehicle. Further, an antenna for detecting the current position and traveling direction of the automobile is fixed on the upper surface of the roof of the automobile.

[0003]

In the above-mentioned conventional vehicle-mounted navigation system, the antenna is installed on the roof top surface or the like. Therefore, when mounting the navigation system, it is necessary to attach the antenna. Moreover, 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 in the passenger compartment,
The work for this wiring is also complicated. Further, since it is premised that the display member and the antenna are installed in different places, it is impossible to remove the display member and the antenna from the automobile and use them as a portable navigation system.

The present invention solves the above-mentioned problems of the prior art, in which the display member and the antenna can always be used in an integrated state, installation of the antenna and wiring in the vehicle compartment are not necessary, and the vehicle is mounted on a vehicle or portable. 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 can be rotated between a main body provided with a monitor screen and a position connected to the main body to cover the monitor screen and a position where the monitor screen appears. A lid is provided, and an antenna for a navigation system is attached to the lid.

In the above, by attaching the antenna to the surface of the lid facing the monitor screen, it can be used as a portable device.

Further, the lid body can be rotated above the monitor screen to a position extending in the direction toward the monitor screen,
By mounting the antenna on the surface of the lid facing upward, the antenna can be used as a vehicle.

Further, the antenna can be detached from the lid or the lid can be detached from the main body, so that the antenna can be used for displaying information other than the navigation system.

[0009]

In the above means, the lid is connected to the main body provided with the monitor screen, and the antenna for the navigation system is attached to the lid. Therefore, it is not necessary to wire the cord connecting the main body and the antenna, for example, in the vehicle interior.

When the antenna is attached to the surface of the lid body facing the monitor screen, the monitor screen and the antenna are protected without being exposed to the outside when the monitor screen is covered with the lid, and are suitable for carrying. .

Further, when used as a vehicle, the lid can be positioned above the monitor screen. As a result, it is possible to prevent external light from directly illuminating the monitor screen, and it becomes easier to see the screen during the day. Further, since the antenna is provided above the lid, it becomes easy to receive a signal wave from a satellite or the like via the windshield when the antenna is installed above the console panel, for example.

Further, by removing the antenna or removing the lid from the main body, it can be used as an application other than the navigation system, for example, as a television receiver or as a game machine or a karaoke monitor.

By G
The BS antenna 15 will also be protected.

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

By attaching the first and second operating members 20 and 30 to the main body 1 and storing the game software in the operating member 20 or 30, 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 monitor for game consoles or karaoke,
If the support base 40 is used, it can be used not only for portable use but also for installation in a car or at home. The antenna is not limited to the GBS antenna, and may be an antenna for receiving a signal wave from another satellite or a detection antenna capable of detecting the position by geomagnetism. Further, the information received by the antenna is not limited to information about the current position and traveling direction that are generally used as a navigation system, and may be traffic congestion information or other traveling information transmitted from a satellite or the like.

[0025]

According to the first aspect of the present invention, since the antenna for the navigation system is attached to the lid body connected to the main body, the cord for connecting the main body and the antenna is wired, for example, in the vehicle compartment. You don't have to.

According to the second aspect of the invention, when the lid is closed so that the monitor screen is covered, the monitor screen and the antenna can be hidden and protected inside the lid body, which is suitable for carrying.

According to the third aspect of the present invention, when the lid is rotated so that the monitor screen is exposed, the lid is positioned above the monitor screen so that the antenna can be easily received. The cover can prevent external light from illuminating the monitor screen, and makes it easier to see the screen during the day.

In the invention according to claim 4, by removing the antenna or the lid from the main body, the antenna is used for a purpose other than the navigation system, for example, as a television receiver, a game terminal, or a karaoke monitor. be able to.
