PURPOSE:To enable a user to change freely the array of key tops to obtain a desired keyboard system by distributing the rewritable memories in response to a group of key tops and changing the contents of these memories. CONSTITUTION:When the array of a group 1 of key tops is changed, a stopper 2 is released to set each key top under a loadable/unloadable state. Then these key tops are rearranged into a desired array. A mode set key 31 of a group 3 of control keys is pushed to set a replace mode for generated key code. When the key code is changed, a key top is pushed and the firmware produces a key code corresponding to the pushed control key top. Then a microprocessor rewrites the key code when a code set key 32 is pushed. This procedure is repeated to rearrange the key tops and to rewrite the key codes. Thus a desired keyboard system is obtained.
