Abstract

PURPOSE: To establish the keyboard which can output any data to each key, by replacing the additional circuit connected to the output side of the keybaord encoder to the memory enabling to read out the data.
CONSTITUTION: The output side of the keyboard encoder KE #1 connected to the key matrix KM #1 is fixed at one arbitrary mode, the output side of the encoder KE #1 is written for the data and is connected to the memories ME #11 to ME #A1 which can read out the data. Further, the selection circuits OP #11 to OP #A11 determining whether either of the memories ME #11 to ME #A1 is made enable condition or not, and the external and internal control circuit MC of mode are provided, the chip enable of the memories ME #11 to ME #A1 or the upper rank bit at the input side is operated, and with this operation, the data is outputted by operating the memories ME #11 to ME #A1 every mode or reading out the designated data in the memories, to output the data not writing in the encoder KE #1.
