摘要
The present invention relates to a keyboard apparatus using the analog one, the encoder switches to be performed by the key input using, in particular, an encoder (Encoder) switch relates to an analog keyboard device.; Conventional analog keyboard apparatus to enable a recognition key for the button keys, but the other keys than the button keys, for example, when the encoder switch has not applicable to this analog keyboard system constraints.; The invention the signal generating means for generating a signal corresponding to a transition of an encoder switch (2) and said encoder switch (2) for inputting data or commands by the user, to solve the above-mentioned conventional pharmaceutical ( predetermined determined by 3a, 3b, 4a, 4b) and a switching means which is switched by a signal generated by the signal generating means constituting the voltage of the predetermined level for the key decoding (5a, 5b) and the switching means by receiving the voltage levels configured analog keyboard device using the encoder switch characterized in that it consists of the decoding means (1) for performing key decoded by determining that the voltage level when switching the encoder to switch the switch (contact ) by using a signal generated according to the time difference between the analog keyboard device using the encoder switch that enables performing the decoding key of the encoder switch Provided.
