Abstract

PURPOSE:To view a picture with superior picture quality, by switching plural antennas alternatively and automatically corresponding to a receiving state in traveling, and switching the antennas by a manual operation selectively in parking. CONSTITUTION:An antenna switching device is provided with a speed switch 40, a manual switch 50 capable of being switched by the manual operation, and a switch control part 60 which controls automatic switching and manual switching. In traveling, an antenna automatic selection signal outputted from a control circuit 36 is inputted with a level as it is to a high frequency switching circuit 20, then, the automatic switching of the antenna is performed. In parking, antenna input corresponding to a control signal selected by the manual switch 50 is selected in spite of the output level of the control circuit 36. Therefore, it is possible to switch the antenna when the antenna is set at a selective state where ghost is generated in parking by finding the antenna possible to receive a wave with a few amount of ghost by the manual operation.
