Abstract

A vehicle-mounted antenna for a vehicle-mounted information processing device performs wireless communication within a vehicle between the vehicle-mounted information processing device located at a rear side of a veneer plate and another electronic circuit within the vehicle. The vehicle-mounted information processing device reads data from a medium inserted via a media insertion opening formed in the veneer plate and executes various processing based on the read-in data. The vehicle-mounted antenna is arranged deeper than the media insertion opening, within a region set if the media insertion opening is extended in a direction substantially orthogonal with the veneer plate.

Claims

1. A vehicle-mounted antenna for a vehicle-mounted information processing device, for performing wireless communication within a vehicle between the vehicle-mounted information processing device located at a rear side of a veneer plate and another electronic circuit within the vehicle, with the vehicle-mounted information processing device reading data from a medium inserted via a media insertion opening formed in the veneer plate and executing various processing based on the read-in data, wherein:

the vehicle-mounted antenna is arranged deeper than the media insertion opening, within a region set if the media insertion opening is extended in a direction substantially orthogonal with the veneer plate.

2. A vehicle-mounted antenna according to claim 1, wherein:

the vehicle-mounted antenna is located on a substrate of the vehicle-mounted information processing device.

3. A vehicle-mounted antenna according to claim 1, wherein:

the vehicle-mounted antenna is provided on an upper side from a media insertion path from the media insertion opening to a media reading position.

4. A vehicle-mounted antenna according to claim 1, wherein:

the vehicle-mounted antenna is located in a position in such a manner that an antenna radiation direction towards a vehicle interior through the media insertion opening does not overlap with the medium when the medium is inserted as far as a media reading position.

5. A vehicle-mounted antenna according to claim 1, wherein:

a periphery of the media insertion opening is constructed from a veneer plate made using a material that blocks electromagnetic waves.

6. A vehicle-mounted antenna according to claim 1, wherein:

the vehicle-mounted antenna is a high-frequency wireless communication antenna.
