Abstract

PROBLEM TO BE SOLVED: To easily and surely adjust a direction in a short time by receiving light emitted from a light emitting device by means of a light receiving device so as to detect the directions of a transmitter and a receiver. SOLUTION: An antenna 1 is fixed to a movable arm 2. The movable arm 2 is fixed to fixtures 3 by a knob 4. After the knob 4 is loosened and the direction of the antenna 1 is moved to a position where a person to hold the antenna can hold it in an easy posture, the knob 4 is loosened. Since the light emitting device 6 is fixed to the movable arm 2, it faces the same direction as that of the antenna 1. Light emitted from the light emitting device 6 is permitted to be received by the light receiving device which is attached to the antenna at an opposite side so that the position and the direction of the antenna 1 are recognized by the opposite side. When distance between the two is short, it is recognized that a light source emitted from the light emitting device 6 of the self-side antenna 1 is reflected by the opposite side antenna so that the direction is surly adjusted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna having a direction adjusting function in a transmitter, a receiver and the like.

[0002]

2. Description of the Related Art FIG. 3 is a diagram showing an example of a transmitter and a receiver according to the prior art. Between the transmission high frequency unit 7 and the transmission control unit 8 and between the reception high frequency unit 9 and the reception control unit 10,
The coaxial cables 11 are connected to each other. The transmission high-frequency unit 7 and the reception high-frequency unit 9 are fixed to the tripod platform 12, and the antenna 14 and the primary radiator 13 are attached to each. The antenna 14 of the transmitting high-frequency unit 7 is oriented toward the installation direction of the receiving high-frequency unit 9, and the direction of the receiving high-frequency unit 9 is temporarily adjusted to temporarily fix the tripod platform 12. Then, the direction of the receiving high frequency section 9 is adjusted while confirming the receiving intensity with the level meter of the receiving high frequency section 9. In order not to match the direction in which the reflected wave comes, the temporary direction adjustment described above is repeated, and after adjusting to the best direction, each tripod platform 12 is fixed and the direction adjustment is completed.

[0003]

The above-mentioned conventional method has the following problems. That is, it takes a lot of time to adjust the direction. Further, when the human being holds the antenna without fixing the antenna to the fixed base, the level meter of the device provided on the fixed base cannot confirm the reception intensity, so that it is not possible to judge whether or not it is aligned with the best direction. SUMMARY OF THE INVENTION It is an object of the present invention to eliminate these drawbacks and to make it possible to perform direction adjustment easily in a short time and reliably.

[0004]

In order to achieve the above object, the present invention is to attach a light generating device to one antenna of a transmitter or a receiver and attach a light receiving device to the other.

As a result, since the position and direction of the antenna can be confirmed from the other side by attaching the light generating device or the light receiving device to each antenna, it is possible to easily adjust the direction in a short time. Further, when the distance between the transmitter and the receiver is short, it is possible to confirm that the light emitted from the light generation device is reflected on the parabola on the other side, so that the direction can be surely adjusted.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, an antenna of a transmitter or a receiver which is used when a person holds an antenna without fixing the antenna to a device will be described with reference to FIGS. .

The antenna 1 is fixed to the movable arm 2.
The movable arm 2 is fixed to the fixed metal fitting 3 with a knob knob 4. A handle 5 is attached to the fixing bracket 3 so that the antenna holder can easily hold it. The light generator 6 is fixed to the movable arm 2 and moves together with the antenna 1.

The method of adjusting the direction will be described below.
After the knob knob 4 is loosened and the orientation of the antenna 1 is moved to a position where the antenna holder can hold it in a comfortable posture, the knob knob 4 is loosened. The light generator 6 is a movable arm 2
Since it is fixed to, it faces the same direction as the antenna 1.
Since the light emitted from the light generating device 6 is received by the light receiving device attached to the antenna of the other party, the position and direction of the antenna can be confirmed from the other party.

[0009]

According to the present invention, the antenna holder can target the light source emitted from the light generating device of the antenna on the other side and determine the orientation so that the light receiving device of the antenna on his side receives the light. it can. Further, when the mutual distance is short, it is possible to confirm that the light source emitted from the light generating device of the own antenna is reflected from the other antenna, so that the direction can be surely adjusted. Furthermore, even in the event of an emergency such as a disaster or at night, even if there is no lighting around,
The direction can be surely adjusted in a short time.
