In the case of a system configuration in which a one-to-one correspondence is not set, a wireless keyboard 10 is conventionally provided with an ID number that is uniquely assigned to each of the wireless keyboards 10 and a receiver that receives data transmitted from the wireless keyboard 10 is provided. A method of identifying and operating only data having a specific ID number is used. This establishes a one-to-one correspondence between the wireless keyboard and the receiver.

When the switch 16 for switching the ID registration mode of the receiver 12 is first pressed, the receiver 12 shifts to the ID registration mode, and becomes ready to receive the notification of the ID number from the wireless keyboard 10. .
In the ID registration mode, the wireless keyboard 10 shown in FIG. 2 uses the cursor keys “←” 18, “↓” 20, “→”.
When the four keys 22, 22 and "@" 24 are simultaneously pressed, the wireless keyboard 10 transmits a wireless keyboard unique ID number different from the key data of the four cursor keys by radio waves. The transmitted key data is received by the receiver 12 so that a one-to-one correspondence between the wireless keyboard 10 and the receiver 12 can be set. The receiver identifies the key data set in a one-to-one correspondence by the ID number notified from the wireless keyboard 10.

As shown in FIG. 3, the wireless keyboard 10 determines whether or not the pressed key is a cursor key (step A1). If the result of determination is that the pressed key is not a cursor key, the flow proceeds to step A4. If the result of determination in step A1 is that the pressed key is a cursor key, it is determined whether four keys have been pressed simultaneously (step A2). If it is determined that the buttons are not pressed at the same time, the process proceeds to step A4. If the result of determination in step A2 is that they have been pressed simultaneously, the ID number is transmitted (step A3) and the process ends. If the cursor key is not depressed at step A1 or not simultaneously depressed at step A2, a normal key code as transmitted is transmitted (step A4).

The key for transmitting the ID number is not limited to a combination of four cursor keys. That is, the key for transmitting the ID number may be, for example, a combination of a plurality of different keys having a combination that is not operated by a normal operation. When operating the plurality of keys, the wireless keyboard does not transmit a normal key code, but transmits an ID number. The ID number is data unique to the wireless keyboard different from the key code.

Next, another embodiment of the present invention will be described. In this embodiment, the ID registration mode changeover switch 16 of the embodiment shown in FIG.
Is pressed, the receiver 12 automatically
It switches to the D registration mode.

The user can select the cursor key “←” 18,
“↓” 20, “→” 22, and “↑” 24 are simultaneously pressed. The wireless keyboard 10 transmits a special code when four cursor keys are pressed. Receiver 12
Switches to the ID registration mode upon receiving the transmitted special code. Next, when the user presses the four cursor keys, the wireless keyboard 10 transmits a unique ID number. The receiver 12 receives the transmitted ID number and receives the ID number from the wireless keyboard 10 and the personal computer 14.
A one-to-one correspondence relationship with the receiver 12 connected to is set.

Also in this embodiment, the key to be pressed is 4
It is not limited to one cursor key. When the four cursor keys are pressed at the same time, no key code is transmitted, so that any combination of a plurality of keys that are not used in normal operation may be used.
