Abstract
PURPOSE: To act the key for faulty key, by providing the output code generation circuit in which the combination of the output codes can arbitrarily be set when the almighty key on the panel of keyboard is depressed.
CONSTITUTION: The almighty key 1 is provided on the panel surface of keyboard, and the output code generation circuit 6 having the dip switch 2 which can arbitrarily set the output code is provided when the key 1 is depressed. Further, when normal key is depressed, the switch at the cross point of the matrix circuit 3 is closed to output one signal from the signal lines X0WX5 and YoWY5, and it is inputted to the code conversion circuit 4 and code signal is outputted to the key output signal line 5. Further, when the key 1 is depressed, the unit code set with the switch 2 in advance is produced from the generation circuit 6 to produce the code signal on the output signal line 5 and code is produced by using the key 1 when normal key is in failure.
