A G-code decoder is coupled to a video tape recorder. When the G-code decoder detects that at least a portion of a G-code will be received or has been received, it checks whether a time clock has been set. If the time-setting is confirmed, the decoder decodes the G-code and terminates the decoding by a terminating means, and, if the time clock is found not to have been set, the decoder indicates the fact at least and terminates the G-code decoding.
