Abstract

PROBLEM TO BE SOLVED: To reduce restrictions on the place where a computer and a data input device are installed by transmitting input data to multiple computers by radio while switching the computers. SOLUTION: A user's input from a data input device (keyboard) 2 or data input device (mouse) 3 is sent temporarily to a radio data input device 1. Here, the user's input is transmitted to a computer previously set as a computer to be operated. When the user changes the computer to be used, the user operates a switch attached to the radio data input device 1 and then the computer to which the input data from the user is transmitted can be changed. Further, the computer to be operated can be changed by operating a specific key on the data input device (keybaord) 2.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wireless data input device switching device that reduces restrictions on a place where a computer and a data input device are installed. Also,
SUMMARY OF THE INVENTION An object of the present invention is to eliminate the hassle of performing wiring by reducing or eliminating wiring connecting between a wireless data input device and a computer.

[0006]

According to the first aspect of the present invention, there is provided a data input device for transmitting an input from a user to a computer, wherein the input data is switched to a plurality of computers. It is transmitted by radio.

As described above, by transmitting the input data from the wireless data input device to the computer wirelessly, there is an effect that there is no restriction on the place where the computer and the data input device are installed as long as the wireless data can be reached.
Also, since the input data is transmitted and received wirelessly, wiring between the wireless data input device and the computer is not required.

[0008] In a second aspect of the present invention, the data input device is a keyboard. Thus, in addition to the effects described in claim 1, even when operating a plurality of computers, the operation can be performed with one keyboard.

According to a third aspect of the present invention, the data input device is a mouse. Thus, in addition to the effects described in claim 1, even when operating a plurality of computers, the operation can be performed with one mouse.

[0010] Further, the invention according to claim 4 is characterized in that the data input device has both a keyboard and a mouse. Accordingly, in addition to the effects described in claim 1, even when a plurality of computers are operated, the operation can be performed with a single set of keyboard and mouse.

According to a fifth aspect of the present invention, the destination computer of the input data is changed by a switch attached to the wireless data input device. Thereby, in addition to the effect described in claim 1, when operating a plurality of computers, it is possible to explicitly determine which computer is being operated from the position of the switch.
Operation errors such as performing an input operation on different computers are reduced.

According to a sixth aspect of the present invention, the destination computer of the input data is changed by a keyboard connected to a wireless data input device. Accordingly, in addition to the effects described in claim 1, when operating a plurality of computers, the computer to be operated is designated by the user's own key input, so that operation errors are reduced.

According to a seventh aspect of the present invention, in the wireless data input device, a transmission destination switching device is built in a keyboard as the data input device.
Accordingly, in addition to the effects described in claim 1, wiring between the wireless data input device and the keyboard is not required, and the required installation area can be reduced by incorporating the transmission destination switching device in the keyboard. Can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In this embodiment, a device shown in FIG. 1 includes a wireless data input device 1 and a data input device (keyboard) 2.
, A data input device (mouse) 3, a computer 4,
It comprises a computer 5 and a computer 6. Here, the number of computers is not limited to three. However, an appropriate number is one to five in terms of the number that can be operated by humans.

A user input from the data input device (keyboard) 2 or the data input device (mouse) 3 is sent to the wireless data input device 1 once. Here, a user input from the data input device (keyboard) 2 or the data input device (mouse) 3 is transmitted to the computer 4 set as a computer to be operated in advance.

When changing the computer operated by the user, a switch 11 attached to the wireless data input device 10 is switched as shown in FIG.
It is possible to change the computer that sends the input data from the user.

In addition to changing the computer operated by the switch 11 attached to the wireless data input device 10 as described above, the data input device (keyboard)
It is also possible to change the computer operated by a specific key operation at 12. In this case, for example, by pressing the escape key and the function key attached to the data input device (keyboard) 12 at the same time, the computer to be operated can be switched by a combination of a plurality of keys, such as switching the computer to be operated. It is possible.

FIG. 3 shows a data input device (keyboard).
32 shows an example in which the wireless data input device 31 is incorporated.
In this manner, by incorporating the wireless data input device 31 in the data input device (keyboard) 32, the installation area can be reduced.

[0020]

As described above, in the wireless data input device of the present invention, the restriction on the place where the computer and the input device are installed can be reduced. Further, the present invention can reduce or eliminate the wiring connecting between the wireless data input device and the computer.
