Abstract

PURPOSE:To ensure an antenna gain most effective in every setting condition by mounting an antenna to a supporting face at an angle of nearly 45 deg. turnably. CONSTITUTION:The abutting face 17 of an antenna 16 is rocked and turned along a supporting face 15 around a supporting shaft 18 to change an antenna main body 19 with respect to a side face 12 at the angle of nearly 90 deg. to 180 deg.. For example, when the antenna main body 19 is set in a direction orthogonal with the side 12, a transceiver main body 11 is set onto a desk in a stable state to attain reception while ensuring sufficiently the antenna gain. Furthermore, when the antenna main body 19 is set obliquitely to the side 12, the main body 11 is stably set onto a desk or onto the dash board of a vehicle while its front side is directed downward. Thus, the antenna gain effective to the utmost is ensured corresponding to every setting condition.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the transceiver of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of an embodiment of the present invention. In the figure, the side surface 1 is attached to the shoulder portion 14 where the adjacent side surfaces 12 and 13 of the main body 11 of the transceiver having a substantially cubic shape contact.
A substantially circular support surface 15 is formed which makes an angle of approximately 45 degrees with respect to the second and the third. On the other hand, a contact surface 17 having a shape matching the support surface 15 is formed at the base end of the antenna 16, and the support surface 15 and the contact surface 17 are rotatably connected via a support shaft 18. ing. The body 19 of the antenna 16 forms an angle of about 45 degrees with respect to the contact surface 17.

Next, the operation of this embodiment will be described with reference to FIGS. By sliding the contact surface 17 of the antenna 16 around the support shaft 18 along the support surface 15, the angle of the antenna body 19 with respect to the side surface 12 is approximately 90 degrees.
You can change from 180 degrees to 180 degrees. For example, as shown in FIG. 2, if the antenna main body 19 is oriented at a right angle to the side surface 12, the transceiver main body 11 is set on the desk with the side surface 12 facing upward, so that the antenna gain is sufficiently secured and standby reception is performed. Can be done. Moreover, the transceiver body 11 can be set on the desk in a stable state.

As shown in FIG. 3, if the antenna main body 19 is inclined with respect to the side surface 12, by setting the transceiver main body 11 with the front surface 20 facing down, on a desk, a car dashboard, or the like, It can be set more stably. Further, as shown in FIG. 4, if the antenna main body 19 is parallel to the side surface 12, the antenna main body 19 can be separated from the user's body when attached to the user's waist or belt clip. Gain can be secured. The antenna body 19 is held by the transceiver body 11 by the frictional force between the contact surface 17 and the support surface 15.

According to the present embodiment, it is possible to secure the maximum effective antenna gain of the transceiver corresponding to all setting conditions. Even when it is attached to the body of the user, it does not interfere with the movement of the body. Furthermore, the antenna can be set on a desk or the like in a stable state to ensure an effective antenna gain.

5 and 6 show the configuration of another embodiment of the present invention. In these figures, the portions corresponding to those of the embodiment shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted as appropriate. In the figure, a flat portion 21 parallel to the axial direction is integrally provided at the tip of the support shaft 18 projecting into the shoulder portion 15 of the transceiver body 11. Also, the flat portion 21
A mounting hole 22 is formed at the center of the. On the other hand, a bracket 23 is integrally formed on the inner wall of the transceiver body 11 in a direction perpendicular to the support shaft 18, and when the antenna 16 is attached to the shoulder portion 15 by abutment, the flat portion 21 is placed on the upper surface of the bracket 23. It comes to abut. Then, the screw 16 is inserted into the mounting hole 22 formed in the flat portion 21 and screwed into the bracket 23, whereby the antenna 16 is fixed to the transceiver body 11.

According to this embodiment, the antenna 16 is set to 180
The antenna main body 1 is rotated by one degree and one of the surfaces of the flat portion 21 is abutted and fixed on the upper surface of the bracket 23.
The mounting angle of 9 with respect to the transceiver main body 11 can be set in two ways. For example, as shown in FIGS. 2 and 3,
Each can be attached and fixed at a right angle or a parallel angle to the side surface 12 of the transceiver body 11.

By forming the flat portion 21 into a prismatic shape, the mounting angle can be set to three or more.

In each of the above embodiments, the support surface 15 is the side surface 12,
Although the case where the support surface 15 forms an angle of about 45 degrees with respect to 13 has been described, the supporting surface 15 forms an angle of about 45 degrees with respect to the side surfaces 12, 13 and the front surface 31 of the main body 11 as shown in FIG. You may form so. In this case front 3
When the main body 11 is set on a desk surface or the like with 1 facing upward, the antenna main body can be erected vertically.

[0018]

According to the transceiver of the first aspect of the present invention, the support surface is formed at the same angle with respect to the surface contacting the shoulder portion of the main body, and the antenna is rotatable on the support surface at an angle of about 45 degrees. Since it is installed, it is possible to secure the maximum effective antenna gain corresponding to all setting conditions of the transceiver body. Also, it does not get in the way when it is attached to the user's body. Moreover, it is possible to secure an effective antenna gain even when it is set on a desk or the like in a stable state.

According to the transceiver of the second aspect,
Depending on the setting conditions of the transceiver body, the antenna can be fixed to the transceiver body in such a direction that an effective antenna gain can be secured.
