Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna installation structure for a wireless POS system. With the spread of mobile phones and mobile phones in recent years, department stores that have introduced POS systems,
Even in supermarkets and the like, there is an increasing demand for wireless data communication from POS terminals.

2.4 GHz for wireless LAN in Japan
Since radio waves in the band were recognized, it is thought that wireless will soon be realized even for portable personal computers. For this reason, the great advantage of wireless communication that communication is possible anytime and anywhere has attracted attention, and there is an active movement toward wireless data communication in the POS system market.

[0003]

2. Description of the Related Art Data communication for sales and inventory management in a conventional POS system is carried out by using a cable between a POS server and a plurality of POS terminals as shown in FIG.

In FIG. 7, reference numeral 2 indicates a POS server, and the POS server 2 and the POS terminal 4 are connected to each other with cables 10 and 11 by mounting a junction box 6 on a wall 8 or accommodating it under the floor. I was doing data communication for sales and inventory management.

[0005]

For this reason, the line construction accompanying the new construction and movement of the POS terminal is required, and the sales and profits of users such as department stores and supermarkets are being squeezed. In addition, new line junction boxes will be installed at bargain sales, year-end sales, and other event venues where food and drinks are frequently moved, as well as food sales floors, to invest new costs and connect line cables to POS terminals. is necessary.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an antenna installation structure of a wireless POS system capable of freely changing the layout of a POS terminal including the movement of the POS terminal. Is to provide.

[0007]

According to the present invention, a POS
An antenna installation structure of a wireless POS system, in which a wireless adapter is connected to a terminal, a wireless base station is connected to a POS server, and wireless communication is performed between the wireless adapter and the wireless base station via an antenna, and an antenna element While standing on the antenna box, connected to the other end of the coaxial cable having a coaxial connector at one end, plug the coaxial connector into the coaxial connector of the wireless base station or the coaxial connector of the wireless adapter, An antenna installation structure of a wireless POS system is provided, wherein an antenna holder is detachably fixed to a structure around the wireless base station or the wireless adapter, and the antenna box is inserted and mounted in the antenna holder. .

[0008]

On the wireless adapter side, a double-sided tape is used to attach the antenna holder around the POS terminal at a high and clear location. Then, the antenna box is inserted into the antenna holder.

When radio waves are irregularly reflected by obstacles and cannot be accurately transmitted / received, the orientation of the antenna can be changed by changing the installation location of the antenna holder without moving the POS terminal. This allows wireless radio waves to be transmitted and received accurately.

On the radio base station side, an antenna can be installed at an arbitrary position on a wall or ceiling by using an antenna fixing bracket to perform sales and inventory management data communication between the POS server and the POS terminal.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 shows an overall configuration diagram of an embodiment of the present invention. A POS server 12 is connected to a junction box 16 mounted on a wall 14 or a junction box 16 housed under a floor via a cable 18.

The junction box 16 is a cable 2
It is connected to the radio base station 20 attached to the wall 14 by 2 or to the radio base station 20 attached to the pillar 28.

The radio base station 20 is connected to the antenna 24 by an antenna cable 26. Antenna 24 on wall 1
4, it can be installed at a suitable place such as the pillar 28 or the ceiling 30.

Reference numeral 32 indicates a POS terminal, on the side surface of which a wireless adapter 34 is attached. The antenna 24 is installed at an appropriate place on the POS terminal 32, and the antenna 24 and the wireless adapter 34 are connected by the antenna cable 36.

Referring to FIG. 2, the antenna 24 is constructed by vertically arranging two antenna elements 40 in an antenna box 38. Each antenna element 40 is connected to a coaxial connector 44 by an antenna cable 42. Diversity wireless communication can be performed by the two antenna elements 40.

Reference numeral 46 denotes an antenna holder, which has two holes 48 for attaching the antenna holder 46 to a wall.
And has two holes 50 for attaching to the ceiling. The antenna holder 46 is formed with a notch 52 for pulling out the antenna cable 42.

Referring to FIG. 3, there is shown a method of installing the antenna on the side of the wireless adapter. As shown in FIG. 3A, the antenna holder 46 is
Attach it to an appropriate place on the side of the S terminal 32. Next, the antenna 24 is inserted into the antenna holder 46.

Since the antenna holder 46 has a simple lock, the antenna 24 is locked in the antenna holder 46. As another attachment method, as shown in FIG. 3B, the antenna holder 46 is attached to an appropriate position on the upper surface of the POS terminal 32 using the double-sided tape 54. Next, the antenna 24 is inserted into the antenna holder 46.

Referring to FIG. 4, the POS terminal 32
The antenna installation example is shown. As described with reference to FIG. 3, the antenna 24 is installed at an appropriate position on the side surface of the POS terminal 32. Reference numeral 56 is a CRT module, and 58 is a printer module.

Referring to FIG. 5, there is shown a method of installing an antenna on the radio base station side. That is, FIG. 5 (A) and FIG.
As shown in (B), the antenna 24 is installed at an arbitrary location on the wall or ceiling using the antenna fixing bracket 60.

Specifically, as shown in FIG. 6, the antenna fixing bracket 60 is screwed and fixed to an arbitrary place on the wall 62, and the antenna holder 46 is screwed and fixed to the antenna fixing bracket 60. Then the antenna 24
Is inserted into the antenna holder 46.

Alternatively, the antenna fixing bracket 60 is screwed and fixed to an arbitrary portion of the ceiling 64, and the antenna holder 46 is screwed and fixed thereto. Then the antenna 24
Is inserted into the antenna holder 46, the antenna 24 is locked in the antenna holder 46 by the simple lock.

According to this embodiment, the antenna 24 and the antenna holder 46 are different in the accessories (double-sided tape 54, bracket 60) used for antenna installation,
The wireless adapter 34 and the wireless base station 20 can be commonly used.

Also, even in POS terminals having different protocols and having the same protocol, the antenna can be connected to different POS terminals by using a connector compatible with the coaxial connector at the cable tip of the antenna.
The communication of the S system can be made wireless.

[0025]

According to the present invention, the following effects can be obtained. (1) The data communication between the POS server and the POS terminal can be made wireless. (2) Since the antenna is externally connected by connecting with a cable, the antenna can be flexibly installed. (3) Since the orientation and / or mounting position of the antenna can be freely changed, irregular reflection of radio waves by obstacles can be prevented or suppressed, and radio waves can be transmitted and received accurately. (4) The antennas of the wireless base station and the wireless adapter can be shared. (5) Even at different POS terminals, the antenna connection can be performed by fitting the antenna connection ports to each other, and the data communication can be wireless. (6) The layout of the POS terminal can be freely changed.
