JPH08250920A - Automatic direction converter for television antenna - Google Patents

Abstract

PURPOSE: To realize an excellent reception state for every channel by directing automatically a television antenna into a direction for each channel to obtain an optimum reception state when a channel is selected by a television receiver. CONSTITUTION: An operation section 1 and a channel setting section 2 allow a direction conversion section 5 to select a direction of a television antenna 6 for each channel in advance through a drive circuit 4 and its channel information is stored in a storage section 3. When the channel setting section 2 selects a channel after the storage, the storage section 3 outputs a turning information signal 10 to the drive section 4 based on the channel information. Then the drive section 4 outputs a direction conversion signal 9 to the direction conversion section 5, which is directed in a preset direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device which can always obtain a good reception state by orienting a direction of a television antenna for each channel.

[0002]

2. Description of the Related Art Conventionally, outdoor TV antennas have been installed in a fixed direction. Moreover, in the case of an indoor antenna, the direction and the like are adjusted for each channel.

[0003]

However, in the case of the outdoor antenna, since the direction of the antenna is constant, if there are a plurality of radio wave transmission facilities and the directions of reception are different, the optimum reception condition for each channel is obtained. Can't get Further, in the case of the indoor antenna, the direction and the like are adjusted for each channel while observing the reception state. An object of the present invention is to automatically orient the television antenna in the direction in which the optimum reception condition is obtained for each channel.

[0004]

In order to achieve the above-mentioned object, the present invention provides a direction changing section capable of changing the direction by connecting a television antenna, which is preset and stored for each channel. By driving the direction changing unit based on the information thus obtained, the direction is changed so as to obtain the optimum reception state.

[0005]

According to the present invention, even when there are a plurality of radio wave transmitting facilities and the receiving directions are different from each other, the optimum receiving state can be obtained in each channel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a block diagram relating to the direction change of a television antenna according to the present invention. The storage mode is selected by the operation unit 1 to enter the storage mode. Next, channel setting section 2
Select the desired channel with. As a result, the channel information signal 7 is output to the storage unit 3. Next, the antenna direction rotation switch of the operation unit 1 is pushed. As a result, the rotation control signal 8 is output from the operation unit 1 to the drive circuit 4. The drive circuit 4 receives the rotation control signal 8 and outputs a direction conversion signal 9 to the direction conversion unit 5. At the same time, the rotation information signal 10 is output to the storage unit 3. Upon receiving the direction conversion signal 9, the direction conversion unit 5 rotates in the specified direction by the specified angle. As a result, the television antenna 6 connected to the direction changing section 5 rotates by the angle described above. The above operation is performed while confirming the reception state, the operation is stopped when the optimum reception state is obtained, and the memory switch of the operation unit 1 is pressed. As a result, the storage unit 3 stores the channel information signal 7 and the rotation information signal 10 as a set as channel information. In this way, the channel information is stored in the storage unit 3 for each channel. When the storage is completed, the operation unit 1 releases the storage mode. After the direction is set, if the desired channel is selected by the channel setting unit 2, the channel information signal 7 is output to the storage unit 3 and the rotation information signal 10 is driven from the channel information already stored in the storage unit 3 by the driving circuit. Output to 4. Upon receiving the rotation information signal 10, the drive circuit 4 outputs a direction conversion signal 9 to the direction conversion unit 5. Upon receiving the direction conversion signal 9, the direction conversion unit 5 rotates in the specified direction by the specified angle. As a result, the television antenna 6 connected to the direction changing unit 5 rotates by the angle described above, and faces the direction in which the optimum reception state of the channel is obtained.

[0007]

As described above, since the direction of the TV antenna can be set while confirming the reception state of the TV receiver, and after the setting, the direction is automatically changed when the channel is selected, the optimum reception is always performed. State can be easily obtained. Also,
By combining with a commercially available high-gain small-sized TV antenna, a compact system can be obtained, wiring of the TV antenna is not required, the installation location of the image receiver is not limited, and the trouble of adjusting the direction and the like is eliminated.
