Abstract

An operation guide system is disclosed which is able to inform an operator only of input operations presently available for a computer, a word processor or the like, and guides operation automatically in case of invalid operation. When an operator taps one of the keys arranged on a keyboard, a key signal is sent out to a key comparison section. The key comparison section determines whether the input key signal is from a key assigned to an available operation in a current operation state or not by referring to information in a key table storing unit. When it is determined that the key signal is not from a presently valid key, it is determined whether a condition for outputting the guide is satisfied or not with reference to a guide condition setting section. If the condition is satisfied, an instruction is given to an operation guide output section to output the operation guide. Further, if the condition is not satisfied, another key signal is awaited. The operation guide output section which receives the instruction outputs the operation guide.
