Abstract

It is an object to provide a sewing machine capable of automatically causing a cloth pressing leg to descend and smoothly executing a work for exchanging a cloth pressing leg, a work for exchanging a needle and a work for aligning a shuttle also in the case in which the cloth pressing leg ascends when a main power source is disconnected. In a sewing machine 1 comprising a cloth pressing spring 24 for always biasing a vertically movable cloth pressing leg 7 in a descending direction and press-up means for lifting the cloth pressing leg 7, the press-up means has a press-up mechanism 30 for lifting and holding the cloth pressing leg 7 against the bias of the cloth pressing spring 24, and a cloth press driving motor 6 for releasing the hold of the press-up mechanism 30 by a driving operation. Moreover, there are provided a smoothing capacitor 72 for holding a power capable of controlling the driving operation of the cloth press driving motor 6 after a main power source is disconnected, and a driving portion 80 and a control portion 90 which drive the cloth press driving motor 6 to bring the cloth pressing leg 7 down by the power of the smoothing capacitor 72 when the main power source is disconnected and the position of the cloth pressing leg 7 is placed at a predetermined height or more.
