OFF-LINE TEACHING APPARATUS

An off-line teaching apparatus comprises an operation command-receiving means for receiving an operation command inputted via an input/output port from a key input device or a coordinate input device and successively storing the operation command in a buffer; an operation command-reading means for successively reading the operation command stored in the buffer; an operation command-counting means for counting a number of operation commands stored in the buffer; and a confirmation sound-generating means for generating confirmation sound upon receipt of the operation command by the operation command-receiving means when a counted value obtained by the operation command-counting means is not less than a predetermined number. Accordingly, the operator can be informed, in real time, of the fact that the system responds to the input of the operation command from the operator. Thus, it is possible to improve the operability of the off-line teaching.
