Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small and lightweight navigation device capable of detecting a current position and displaying the position on a map.

[0002]

2. Description of the Related Art Conventionally, on-vehicle navigation devices that detect the position of a vehicle and display the position of the vehicle together with a map screen have been manufactured and sold, and are widely used by users. There are two types of navigation devices, one is a dedicated type that is simultaneously attached to the vehicle when the vehicle body is manufactured, and the other is a general type that is purchased by the user and attached to the vehicle after the vehicle body is completed.

In the latter case, the navigation device usually uses GPS (Global Positioning) for satellite positioning.
oning system), a screen display unit, a processing unit that realizes the original functions of the navigation device, a navigation device body that houses a hard disk drive, and a remote control unit.

The remote control unit is used when a driver or a passenger (including a passenger in the rear seat) remotely operates the navigation device body, and is connected to the navigation device body by wire or wireless (infrared rays, etc.). It is electrically connected.

[0005]

To install the navigation device in a vehicle, the navigation device body is placed in the rear trunk or under the seat, and the antenna part is attached to the outside of the vehicle body (for example, on the roof). It is necessary to fix the screen display unit in a position visible from the driver and connect these with a harness or a cable.

However, in the navigation device having the above-mentioned configuration, in addition to the fact that the screen display unit must be fixed at a position visible to the driver in the vehicle, the remote control unit must be placed somewhere in the vehicle. I won't. Therefore, it takes a double space,
The problem arises. Therefore, it is desired to develop a simple navigation device that requires less installation space and is easy to use.

When pushing forward with the concept of such a simple navigation device, the idea is to place the screen display unit and the remote control unit in one place inside the vehicle, provided that a small screen is used. Is born. However, until now, there was an idea that the screen display unit is what the driver sees and the remote control unit is what the driver touches with the hands.When the remote control unit and the screen display unit are put together, Since the operator's line of sight is concentrated on the screen during the operation, it is considered that it hinders driving, and such an idea has not been easily realized.

However, since the driver who actually drives the vehicle cannot look aside while driving, he cannot see the screen display unit, much less the remote control unit. Therefore, the remote control unit can be operated only when the vehicle is stopped, but when the vehicle is stopped, there is no inconvenience even if the driver's line of sight concentrates on the screen, rather, If the operation keys and the screen are close to each other, there is an advantage that the movement of the line of sight is reduced and the user can concentrate on the operation.

Although it is possible for passengers other than the driver to operate it while the vehicle is driving, passengers in the rear seats or adjacent seats can take off their seat belts while holding the remote control unit. If an operation is carried out in which the driver goes out to the front and looks at the screen of the front seat (the screen of the screen display unit is small, such an operation is sufficiently expected), it is a very unfavorable situation for safety. Therefore, it is preferable for the passengers in the rear seat or the adjacent seat that the operation keys are closer to the screen because the movement of the line of sight can be reduced and the operation can be concentrated.

Therefore, an object of the present invention is to realize a simple navigation device which requires a small installation space, can be easily used, and can ensure traveling safety.

According to this navigation device, the installation is completed simply by fixing the main body of the navigation device to any place in the vehicle (for example, in the trunk or under the seat). After that, if the screen display unit and the remote control unit are connected with a connecting device, both can be carried as one unit, so it does not take up much space. Further, the movement of the line of sight during the operation is reduced, and the user can concentrate on the operation.

Further, when the screen display unit is used separately from the remote control unit, a fixing device for stopping the screen display unit at any place in the vehicle may be further provided (claim 2). . With this configuration, since the screen display unit and the remote control unit can be separated,
The screen display unit can be placed on the dashboard and the remote control unit can be used anywhere. (2) In the navigation device of the present invention, the screen display unit is physically separated from the main body of the navigation device, and the screen display unit and the remote control unit can be physically combined into one. When the screen display unit and the remote control unit are equipped with a device and are used as a navigation device in a state where they are physically coupled by the coupling device, the screen display unit and the navigation device body are electrically connected. The remote control unit is provided with a connection terminal for mediating the above (claim 3).

In this configuration, since the remote control unit is provided with the connection terminal, the screen display unit and the remote control unit can be connected by connecting the screen display unit when the screen display unit can be connected by the connecting device. The display unit is connected to the navigation device body. Therefore, means for directly connecting the screen display unit to the main body of the navigation device by wire or wireless becomes unnecessary.

Further, a connecting terminal, which mediates electrical connection between the screen display unit and the navigation device body, is provided not in the remote control unit but in the coupling device, and the coupling device is connected to the navigation device body and the wired device. Alternatively, they may be electrically connected wirelessly (claims 4 and 5). In this case, when the screen display unit can be coupled with the coupling device, the screen display unit and the coupling device are connected to connect the screen display unit to the navigation device body. Even with this, it is possible to obtain the same effect as that of the invention described in claim 3.

Further, when the screen display unit and the remote control unit are physically separated from the coupling device and used as a navigation device, a fixing device for stopping the screen display unit at any place in the vehicle is provided. The fixing device further includes a connection terminal that mediates electrical connection between the screen display unit and the navigation device body, and the fixing device is electrically connected to the navigation device body by wire or wirelessly. (Claim 6).

In this configuration, the fixing device for stopping the screen display unit at any place in the vehicle is provided with the connection terminal. Therefore, if the screen display unit is connected by the connecting device, the screen display unit is automatically connected. It is connected to the navigation device body. Therefore, also in this case, a means for directly connecting the screen display unit to the main body of the navigation device by wire or wireless becomes unnecessary. (3) Further, in the navigation device of the present invention, the screen display unit is physically separated from the navigation device body, and the screen display unit is integrally incorporated in the remote control unit (claim) 7).

According to this structure, the installation is completed simply by fixing the navigation device body to any place in the vehicle (for example, in the trunk or under the seat). After that, since the screen display unit and the remote control unit can be carried as one unit, the navigation device can be operated from any position in the vehicle. Further, the movement of the line of sight during the operation is reduced, and the user can concentrate on the operation.
