作制御装置。[Claims for Utility Model Registration] A pedal that can be operated to move between one position that generates a drive signal and the other position that is separated from the position and generates a stop signal; A means for detecting the generated rotation, a driving body of the sewing machine that is connected to the main shaft and can be electrically driven or stopped, and a reverse feed operation that is electrically connected to the cloth feeding means so as to reverse the cloth feeding direction. a control circuit having an adding circuit for adding rotation signals and generating a coincidence signal in relation to the coincidence of the added value and the set value; It is possible to switch between an automatic sewing state in which the driving body is stopped in relation to the generation of a signal and a normal sewing state in which the driving body is driven in relation to the generation of a drive signal and stopped in relation to the generation of a stop signal. A sewing machine having a first drive circuit configured to perform automatic sewing and a setting means capable of setting the first drive circuit to an automatic sewing state or a normal sewing state, and capable of selectively performing automatic sewing and normal sewing. an operating body that alternately generates an action signal or a non-action signal; a second drive circuit that drives the driving member in response to the generation of the action signal and stops the driving member in relation to the generation of the non-action signal; and an action signal. an energizing circuit that activates the reverse feed actuating means in connection with the occurrence of the signal and deactivates the reverse feed actuating means in connection with the generation of the deactivation signal; Operation control of a sewing machine equipped with a switching circuit that enables switching to a correction sewing state that connects a second drive circuit to a reverse stitching state that connects an operating body and an energizing circuit in connection with setting the normal sewing state.
