摘要： PROBLEM TO BE SOLVED: To provide a digital broadcast receiver for a mobile object, in which the generation of the switching noise of broadcast output due to the movement of the mobile object is suppressed.
SOLUTION: A traveling state indicating whether a vehicle as the mobile object is actually stopped or traveling is judged. Then, when it is judged that the vehicle is traveling, the broadcast output is switched from digital broadcast for fixed receivers to the digital broadcast for the mobile object. Also, when it is judged that the vehicle is stopped, while the broadcast output is switched from the digital broadcast for the mobile object to the digital broadcast for the fixed receiver as a principle, the broadcast output is switched from the digital broadcast for the fixed receiver to the digital broadcast for the mobile object exceptionally only in the case where the reception conditions of the digital broadcast for the fixed receiver are relatively degraded.

摘要： PURPOSE:To always secure the best receiving performance by providing a pickup coil for resonance and a mismatching loss reducing pickup coil which have been wound and installed to a ferrite core so that an induced current is induced, based on a magnetic flux which has been collected to the ferrite core which has been embedded so as not to form a projecting part on the outside surface of a car body. CONSTITUTION:A ferrite core 14 is embedded in a recessed part 12 of a car body outside plate 10. Also, to the ferrite core 14, resonance use and mismatching loss reducing pickup coils 20, 22 are wound, and to its pickup coil 20, a capacitor 23 and a variable capacity diode 26 which have been connected in series are connected in parallel. In this way, since there is no projecting part on the surface of the car body, such inconveniences as in a conventional case in which many pieces of pole antennas have been provided in parallel are all obviated. Also, since a mismatching loss is reduced, the antenna can always secure the best receiving performance.

摘要： PURPOSE:To effectively detect a current induced in a car body from a broadcast wave and to send it to an on-vehicle receiver by providing an outer metallic member and an antenna wire arranged prolongedly along the car body incorporatedly while electric insulation is kept. CONSTITUTION:A metallic side lace 32 is arranged prolongedly along the car body while being electrically insulated from a roof panel 36 and a header inner panel 38 by a resin-made space 34. Further, a resin part 40 formed incorporatedly with the lace 32 along the lengthwise direction is provided to one side ridge of the lace 32, the antenna wire 42 is imbedded in the resin part 40 and positioned and fixed surely in a range depending on the carrier frequency of a broadcast wave. Thus, it is possible to make the lace 32 as nearly a half wavelength for a lower band in the VHF band, nearly one wavelength for a high band and as nearly 2-4 wavelengths for the UHF band thereby causing the surface current to be easily concentrated. That is, the current induced on the car body by the broadcast wave is detected effectively and sent to the on-vehicle receiver.

摘要： PURPOSE:To improve remarkably the antenna directivity without making the external appearance of the car body poor by constituting a diversity reception antenna with high frequency pickups detecting a high frequency surface current flowing concentratedly onto a front pillar and a center pillar. CONSTITUTION:The high frequency pickup 44a or 46a is built respectively in the front pillar 40a or the center pillar 42a suppporting a ceiling plate and the high frequency pickups 44a, 46a consist, e.g., of electromagnetic pickups including a loop coil. Then, for example, the diversity reception is attained by using the four high frequency pickup provided to the front pillar and the center pillar at both sides of the car body. Thus, the derection of low sensitivity is compensated together and the best TV reception is attained. Further, the high frequency surface current flowing concentratedly onto the center pillar 42 is caught surely by the loop coil at a high frequency band and the reception with high sensitivity is attained by means of a built-in antenna not-projected externally.
