Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for indicating a current position, a heading, etc. to support the operation of a moving body such as an automobile, and particularly to specify a desired spot and register the spot name. The present invention relates to a navigation device having a means for performing.

[0002]

2. Description of the Related Art In a navigation device mounted on an automobile or the like, a vehicle position and a heading are accurately measured, and map information corresponding to a vehicle position, that is, a current position, a vehicle position mark, and a mark indicating a heading, Alternatively, it is required to sequentially and accurately display other information in response to the user's request on a display or the like and present it to the driver.

Conventionally, a navigation device mounted on an automobile or the like has a function of spot registration for recognizing a designated spot on a map and displaying the spot registered by each user as a mark. Further, in this point registration, a point name can be registered so that it is easy to understand when quoting a desired point when searching for a place. The point name is usually registered by designating the characters displayed on the screen one by one.

[0004]

As described above, in the conventional spot registration, it is necessary to register the spot name because the registered spot must be identified when the place is searched later. However, designation of characters in registration of a place name is a laborious task, and thus registration with sufficient discriminating power has not been made in a urgent case.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a navigation device in which a spot name having distinctiveness is quickly registered and the convenience of spot registration is improved.

[0006]

A navigation device of the present invention for solving the above-mentioned problems is a point registration means for registering character information designated and input as a point name corresponding to a specified point on a map. In the navigation device, the spot registration means is configured to acquire date and time information and register it as the spot name when a registration instruction is made without inputting text information.

[0007]

In the navigation device of the present invention, a desired spot on the displayed map is designated, and subsequently, when registering a spot name to be designated and input, the spot registration means receives the character information and inputs the registration instruction. If there is, the input information is registered as a spot name, but if there is a registration instruction without inputting character information, date and time information is obtained and registered as a spot name.

Thus, in a case where the user is in a hurry, the spot registration is performed only by inputting a desired spot instruction and a registration instruction. Moreover, date and time information is registered as the point name.
Since the date and time information indicates the time at the time of input even if a plurality of date and time information is registered, it has sufficient discriminating power.
