Abstract
Disclosed is the invention in connection with an electric sewing machine comprising a machine bodyand a controller, wherein the controlleris responsive to a first press to produce a signal for starting the machine bodyand is responsive to further press to produce a signal for driving the machine bodyat a stitching speed (drive speed) in accordance with the pressing amount. The machine bodyis provided with a control devicewhich is connected to a changing devicewhich is operated to change the control content of the control device. The changing devicemay be operated to switch the control devicebetween being operative and being inoperative. In case the control deviceis switched to being inoperative, the control deviceneglects the instruction signal from the controller, for example, produces a stop signal to a motor drive devicein response to a machine drive signal from the controller, thereby to maintain the machine motor as stopped. Therefore, if the changing deviceis selectively operated beforehand to switch the controllerto being inoperative, the machine bodywill not driven in response to the instruction signal from the controllerwhich may be wrong operated. Thus the safety may be secured.
