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

FIGS. 1 and 2 are views for explaining the first embodiment, and are a side view and a perspective view of a state in which two radios are stacked.

The housing 12 of the wireless device 11 has a bar-shaped antenna 13 provided upright on the upper surface 12a and a bottom surface 12 of the housing 12.
A recess 15 is formed on the b side. This recess 15 is
It is formed in a groove shape slightly wider than the diameter of the antenna 13, and is open to both side surfaces 12c, 12c of the housing 12.

With such a structure, the wireless device 11A of the same structure in which the wireless device 11 is placed on the installation surface 17 is provided.
In the case of installing the antenna (other antenna) 13A standing on the housing 12A of the radio device 11A, the recess 15
By arranging it inside, both radios 11 and 11A can be brought into close contact with each other and can be installed in a minimum space.
In this case, since the concave portion 15 is open on both side surfaces 12c, 12c and the bottom surface 12b side, the wireless device 11 can be installed in the wireless device 11A from above or from the lateral direction.
Can be placed on top.

Since the wireless device 11A also has the recess 15A, it can be similarly stacked on another wireless device having the same structure. Further, a plurality of antennas 13 may be provided upright on the housing 12.

FIG. 3 is a diagram for explaining the second embodiment.

The housing 22 of this radio 21 has an upper surface 2
An antenna 23 is rotatably attached to the 2a via a rotating portion 24, and a concave portion 25 having an opening is formed on a bottom surface 22b and a side surface 22c. This recess 25
Is formed in a size large enough to accommodate an antenna having the same shape as the antenna 23.

With such a structure, the wireless device 21A having the same structure with the wireless device 21 placed on the installation surface 27 is provided.
In the case of arranging above the antenna, the antenna 23A standing on the housing 22A of the radio device 21A is placed inside the recess 25, so that both radio devices 21 and 21A can be installed in the minimum space. In this case, since the concave portion 25 is also open on the side surface 22c side, the antenna 23A can be rotated in the range of 90 °.

Since the wireless device 21A also has the recess 25A, the wireless device 21A can be mounted in a state of being in close contact with another wireless device having the same structure.

FIG. 4 is a diagram for explaining the third embodiment.

In the case 32 of the radio device 31, an antenna 33 is rotatably attached to one of the opposite side surfaces 32a and 32b via a rotating portion 34, and
On the other side surface 32b side, a concave portion 35 is formed in a notched state from the upper surface 32c to the bottom surface 32d. This recess is formed to have a size sufficient to accommodate an antenna having the same shape as the antenna 33.

With this structure, this radio 31 is replaced with another radio 31A having the same structure as this radio 31.
When it is mounted on the installation surface 37 together with it, the antenna 33A provided in the housing 32A of the wireless device 31A can be disposed in the recess 35, so that both wireless devices 31, 31A can be adjacent to each other. In this case, the concave portion 35 is formed from the upper surface 32c to the bottom surface 3c.
Since it is formed to reach 2d, the antenna 33A
Can be moved in a range of 180 °.

Since the radio device 31A has the recess 35A, the radio device 31A can be adjacent to another radio device having the same structure.

FIG. 5 is a diagram for explaining the fourth embodiment.

In the case 42 of the radio device 41, an antenna 43 is rotatably attached to one of the opposite side surfaces 42a and 42b via a rotating portion 44, and
On the other side surface 42b side, a recess 45 is formed in a state of being cut away from the upper surface 42c to the middle.

With such a structure, when the radio device 41 is placed on the installation surface 47 together with another radio device 41A having the same structure as the radio device 41, the housing 4 of the radio device 41A is used.
Since the base portion of the antenna 43 provided in 2A can be arranged in the recess 45, both radio devices 41, 41A can be adjacent to each other. In this case, since the concave portion 45 is formed from the upper surface 42c to the middle thereof, the antenna 43A can be moved within the range of 90 °.

Since the radio device 41A has the concave portion 45A, the radio device 41A is also adjacent to another radio device having the same structure.

FIG. 6 is a diagram for explaining the fifth embodiment.

In the case 52 of the radio device 51, an antenna 53 is rotatably attached to a predetermined side surface 52a via a rotating portion 54, and a top surface 52b to a bottom surface 52c are provided on the side surface 52a side. The concave portion 55 is formed in a state in which the concave portion 55 is cut out.

With such a structure, when the wireless device 51 is installed on the installation surface 57 together with another wireless device 51A having the same structure as the wireless device 51, the antenna 53 of the wireless device 51 is replaced with the wireless device 51A. Since the antenna 53A of the wireless device 51A can be disposed in the recess 55A of the wireless device 51, the wireless devices 51 and 51A can be adjacent to each other without the antennas 53 and 53A protruding laterally.

Since the recesses 55 and 55A are formed so as to extend from the top surface to the bottom surface, they can be rotated within a range of 180 °.

[0030]

As described above, in the radio device of the present invention, the recess for arranging the antenna of another radio device is formed on the outer surface of the housing. Therefore, when a plurality of radio devices of the same type are arranged. Can be arranged in a minimum space by disposing the antenna of one radio in the recess of the other radio.
