Abstract

PURPOSE:To optionally assign a desired key code to each key, by providing a key code setting means on each key body placed on the keyboard and changing this output signal optionally, in a key code setting circuit incorporated in each key body. CONSTITUTION:An operator is able to set a desired key code to each key by setting or resetting a switch Si. That is to say, when a key switch KS is depressed, a high or low difference is generated in a voltage level of a signal line (bi) by a set state of the switch Si, and by an electric signal by said level difference, a key code corresponding to the depressed key is outputted. The operator is able to set a key code by turning on an optional switch in the switch group Si, and in the same way, is able to set a key code to each key on the keyboard, and is able to assign a desired key code to each key accordingly.
