Abstract: A display device whereby appropriate operation control desired by a user can be conducted is implemented even if an image for driver's seat which can be seen by a driver but cannot be seen by a passenger in a passenger seat and an image for passenger seat which can be seen by the passenger in the passenger seat but cannot be seen by the driver are displayed on a common screen. The display device comprises a unit for conducting operation control on an image with priority of an image GDR for driver's seat and an image GPA for passenger seat when an operation is performed to an operating switch arranged in such a manner that the operation area for the image GDR for driver's seat on the display screen and the operation area for the image GPA for passenger seat on the display screen overlap each other.

Abstract: The present invention provides a mobile receiver, whereby the power consumption can be kept as lower as possible, as the size of the automobile equipment control system, the placement space thereof and the cost can be reduced, since an antenna and part of receiving circuits for keyless entry system are also used as those of a mobile radio receiver. Moreover, in order to prevent the users from feeling inconvenience in its use, the mobile receiver has a construction wherein a mixing circuit, a local oscillator circuit and the like for keyless entry system and those for radio receiver are separately arranged though the antenna and an intermediate frequency amplifier circuit are used both for keyless entry system and for radio receiver. As a result, signals from the remote control side can be received even while someone is listening to the radio.
