Information processing apparatus |
摘要 |
An information processing apparatus is capable of using more than one type of keyboard with a single keyboard controller without increasing the production cost. In a keyboard matrix, a key scanning line C0 is arranged so that the key scanning line C0 is only connected to any one of key return lines R0 to R7 through a key switch having a key switch number G01. The key switch number G01 is assigned for the key [F1] which is common to keyboards having different key arrangements. When the information processing apparatus is activated, a keyboard initializing program is activated by depressing the [F1] key. As a result, the information processing apparatus identifies the type of the keyboard by detecting a key return line R from which a signal is returned when scanning is made upon the depression of the [F1] key.
