Abstract

PURPOSE:To enlarge the freedom degree of a layout, to enlarge the moving probability of a terminal, and to utilize a wrap top type terminal especially without sacrificing its characteristic by connecting a terminal controller and a terminal by means of radio. CONSTITUTION:In a terminal controller 1 to have received data from a host, etc., the data are transmitted through a cable arranged, for example, on a ceiling to radio communication equipment 2. The data to be sent include an ID to discriminate terminals 4 to 6, namely, a unit address, and the data are selectively received by radio communication equipment 3 with the use of the ID. On the terminal 4 to 6 sides, received signals are processed and sent from the radio communication equipment 3. The signals are received by the radio communication equipment 2, sent to the terminal controller 1, and sent to the host. Thus, the constraint of the setting condition of the equipment is eased, and especially when the wrap top type equipment is used for the terminal, it can be utilized without sacrificing portability.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a connection between a terminal control device and a terminal, and particularly to a wireless connection method using wireless communication.

(Prior art) Conventionally, a cluster system configured by connecting a terminal control device and a terminal has a serial interface cable,
Alternatively, a method using a LAN cable or wired cable has become publicly known.

(Problems to be Solved by the Invention) The conventional connection method between the terminal control device and the terminal described above has the following problems:
Due to the cable connection, equipment installation conditions were severely restricted. Especially a laptop-type machine? ) is used in a terminal, it has the disadvantage of sacrificing its portability.

An object of the present invention is to eliminate the above drawbacks by wirelessly connecting a terminal control device and a terminal, and to provide an inter-device connection system configured so as not to lose portability.

(Means for Solving the Problems) A device connection method according to the present invention includes one or more first wireless communication devices for transmitting and receiving data transmitted and received by a terminal control device, and data transmitted and received by a plurality of terminals. This configuration includes a plurality of second wireless communication devices for communicating with each other.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the device-to-device connection method according to the present invention.

In FIG. 1, 1 is a terminal control device, 2 is a wireless communication device placed on the terminal control device 1 side, 4 to 6 are respective terminals, and 3 is a wireless communication device placed on the terminal 4 side. Terminal 5 represents a laptop type, and terminal 6 represents a printer.

FIG. 2 is a perspective view showing how each device is arranged according to the configuration of FIG. 1.

When the terminal control device 1 receives data from a host (not shown), the data is sent to the wireless communication device 2 via a cable arranged on the ceiling, as shown in FIG. 2, for example. The transmitted data includes an ID for distinguishing each terminal 4 to B, that is, a unit address, and the data is selectively received by the wireless communication device 3 using the ID.

The terminals 4 to 6 process the received signals and transmit them from the wireless communication device 3. This signal is received by the wireless communication device 2, sent to the terminal control device 1, and then sent to the host. For data communication between the wireless communication devices 2 and 3, in addition to transmission and reception using radio waves, transmission and reception using light can be considered.

In FIG. 2, a wireless communication device 2 on the terminal control device 1 side
If the number is greater than the number of terminals 4 to 6, this indicates that any terminal may be assigned to an available wireless communication device 2.

In particular, this concept is considered to be extremely effective for laptop terminals such as terminal 5.

(Effects of the Invention) As explained above, the present invention enables expansion of the degree of freedom in layout and expansion of the mobility of the terminal by wirelessly connecting the terminal control device and the terminal. It has the advantage that it can be used without sacrificing the features of a laptop terminal.
