Description

ABSTRACT:
A sewing machine aurally informs an operator of abnormal conditions which accidentally have taken, or are taking, place by means of a vocal indication. One group of speech data corresponding to an accidentally occurring abnormal condition is selected from among plural groups of speech data according to a detection signal from a plurality of abnormal condition detectors disposed in the machine. A voice signal corresponding to the selected group of speech data is generated in relation to operation of a manual device e.g. a button such as a switch, for the start of sewing. The operator can hear the warning voice due to this vocal indication simultaneously with the operation of the manual button for the start, whereby he/she is prevented from starting of the machine while the abnormal condition exists.
