As shown in the cooling fan unit of FIG. 11B, the cooling fan 1105 of the receiving unit can adjust the orientation of the main antenna 21 provided separately on the propeller unit 1105a of the cooling fan 1105. For this purpose, the sub antenna 22 is mounted. Here, the sub-antenna 22 rotates at the same rotational speed as the propeller unit 1105a of the cooling fan 1105 rotates, and is installed so that the direction of the sub-antenna 22 changes according to the rotation of the cooling fan 1105. .

  On the other hand, as shown in the antenna direction detection circuit block unit in FIG. 11A, the television signal received by the sub-antenna 22 is transmitted to the reception sensitivity detection unit 1103, but the reception sensitivity detection unit 1103 receives the television signal. It has a function of detecting the reception sensitivity (reception power) of the selected frequency band designated by the CPU 1101 from the television signal. Further, the rotation control unit 1104 has a function of detecting rotation angle information indicating to which position the sub antenna 22 installed in the cooling fan 1105 is rotating. The cooling fan 1105 normally rotates at a high speed in order to cool the receiving unit. However, when detecting the optimum position of the sub antenna 22, the cooling fan 1105 operates as follows.

  The CPU 1101 specifies the channel selection frequency band and the antenna direction detection mode to the reception sensitivity detection unit 1103. The reception sensitivity detection unit 1103 that has received the designation of the antenna direction detection mode operates to measure the reception sensitivity from the sub-antenna 22 in the channel selection frequency band designated by the CPU 1101. Further, the reception sensitivity detection unit 1103 sets the rotation of the cooling fan 1105 at a low speed with respect to the rotation control unit 1104, so that the cooling fan 1105 is mounted on the propeller unit 1105a. At the same time, it starts to rotate at a low speed. In the reception sensitivity detection unit 1103, in order to detect the rotation angle at which the antenna reception sensitivity selected and received by the sub antenna 22 is maximized, the reception sensitivity and the rotation position of the sub antenna 22 at that time are displayed from the rotation control unit 1104. The CPU 1101 is periodically notified of the rotation angle information. The CPU 1101 calculates the rotation angle of the sub-antenna 22 that maximizes the reception intensity for a certain period of time, and displays the calculation result on the display unit 1102.

  The display method on the display unit 1102 is a graphical display, in which direction the rotation angle or direction of the sub antenna 22 is relative to the front surface of the liquid crystal panel, and in which direction the direction of the main antenna 21 provided separately is. The display should make it easy to identify whether the adjustment should be made. Based on this information, the user adjusts the orientation of the main antenna 21 to the same orientation as that of the sub antenna 22 displayed on the display unit 1102. When the orientation of the main antenna 21 is adjusted, the reception sensitivity detection unit 1103 detects the reception sensitivity of the main antenna 21, notifies the CPU 1101, and displays the result on the display unit 1102. The adjustment of the orientation of the main antenna 21 can also be facilitated.

  In the example described above, the reception sensitivity detection unit 1103 and the CPU 1101 calculate the rotation angle information that averages the reception sensitivity for a certain period of time, but the reception sensitivity detection unit 1103 receives the information from the CPU 1101. The rotation angle information and the reception intensity information may be detected only when there is an instruction. Further, the propeller unit of the cooling fan 1105 is set to the designated rotation angle by designating the rotation angle of the sub-antenna 22 instead of designating the mode relating to the low or high rotation speed to the rotation control unit 1104. You may make it adjust the position of the subantenna 22 by rotating the position of 1105a.

  In the above-described example, the user has adjusted the orientation of the main antenna 21 based on the information on the display unit 1102. However, when the user has a function that allows the orientation of the main antenna 21 to be automatically adjusted, It is possible to automatically adjust the orientation of the main antenna 21 to an optimal position during viewing without disturbing the user's hand. In this case, the main antenna 21 is provided separately from the sub-antenna 22 installed in the propeller unit 1105a of the cooling fan 1105. However, the rotation can be rotated to an arbitrary angle in response to the rotation angle designation from the CPU 1101. By being configured in a free state and specifying the same rotation angle as that of the sub-antenna 22, the orientation of the main antenna 21 can be rotated to an optimum state.

  That is, the main antenna 21 has a function capable of rotating and adjusting to the angular position detected as the angle information with the maximum reception sensitivity of the sub-antenna 22, so that the direction of the main antenna 21 can be adjusted by designation from the CPU 1101. Yes. The timing for automatically adjusting the orientation of the main antenna 21 can be automatically adjusted when it is detected that the reception state has deteriorated and the video cannot be displayed correctly. Further, the optimum position of the main antenna 21 is measured and stored in advance for each channel using the sub-antenna 22 set in the cooling fan 1105 at the time of channel search, and the channel is selected for the next channel selection. It is also possible to adjust and set the direction to the optimum position of the corresponding main antenna 21.

In the above-described embodiment, the optimum position of the main antenna 21 is detected by the sub-antenna 22 provided only in one cooling fan 1105. However, a plurality of coolings each provided with a plurality of sub-antennas 22 independently. By arranging the fans 1105 in different directions, for example, one cooling fan with the sub-antenna 22 is arranged in the horizontal direction, and the other one with the sub-antenna 22 is arranged in the vertical direction. It is also possible to detect the optimum direction of the main antenna 21. In addition, the main antenna 21 may be controlled not only in one direction but also in the horizontal direction and the vertical direction, and may be automatically adjusted to the optimal direction of the main antenna 21 in three dimensions.
As described above, in the liquid crystal television of FIG. 11, the cooling fan 1105 is configured to have all or part of the antenna function.
