Abrégé
(EN)
An IR keyboard 1 generates key code information corresponding to key operated to add break flag information indicating distinction between in-operation and operation release to the key code information as operation status information of the key to add terminator code information indicating that the key code information corresponding to key operation every once is completed to the last portion of the key code information to transmit, as key operation information, the key code information, the break flag information and the key code information by an infrared ray signal from a light emitting unit 11. Further, a light receiving unit 2 receives the infrared ray signal transmitted from the light emitting unit 11 to input key operation information of the IR keyboard 1 to a computer unit 3. At the light receiving unit 2, a control is conducted such that in the case where receive signal is ceased to be received in the state where break flag information added to key code information included in the infrared ray signal transmitted from the light emitting unit 11 of the IR keyboard 1 indicates that the key is being operated, when clocking operation starts from the time point of occurrence of fault and a receive signal can be obtained within a predetermined time, the receive signal is considered to be continuously received.

(ZH)

IR键盘1产生与所操作的键对应的键码信息,把表示正处在操作之中和操作已释放之间的区别的中断标志信息加到键码信息中作为键操作状态信息,把表示与每次键操作相对应的键操作信息已被完成的终结码加到键码信息的最后部分中;通过来自发光单元11的红外线信号发射键码信息,中断标志信息和键码信息作为键操作信息。进一步,光接收单元2接收从发光单元11发射出来的红外线信号,并把IR键盘1的键操作信息输入到计算机单元3。在光接收单元2中,进行一个控制,以便在被加到包含在IR键盘1的发光单元11发射出来的红外线信号中的键码信息的中断标志信息表示键正处于操作之中的状态下,如果接收信号被停止接收,则当计时操作从错误发生的时刻开始,并且可以在一个预先确定的时间内获取接收信号时,认为该接收信号是连续地被接收的。
