The present invention relates to a sewing machine table. The sewing machine table with a rotatable operating foot pedal connected to a driving motor for a sewing machine, comprises: an upper frame provided with a top plate on which the sewing machine is installed, and a lower frame including: height adjustable supports provided at bottom ends of the upper frame for supporting the top plate and adjusting a height of the top plate; lower supports coupled to bottom ends of the height adjustable supports, and a first lower connecting plate coupled between the lower supports, the first lower connecting plate on which the operating foot pedal is installed. With this configuration, the sewing machine table is provided with an upper support coupled to a top plate and a cylinder inserted in the upper support and capable of adjusting a height, thereby enabling a height of the top plate to be adjusted according to a body size of an operator and increasing work efficiency.

A foot-operated controller of a sewing machine including a first pedal that input a number of revolution of a sewing machine motor by stepping of a user, a second pedal pressed by the user, a main body that supports the first pedal, and a support unit that supports the second pedal, in which the support unit is selectively attachable in disposition where the second pedal is on the left side of the first pedal and disposition where the second pedal is on the right side of the first pedal. In both cases where the second pedal is on the left side of the first pedal and the right side of the first pedal, across an interval between the main body and the support unit, it is possible to detect the pressing to the second pedal with respect to the second element.

A sewing machine including a detection portion that detects a movement amount of a workpiece, a sewing machine motor that serves as a driving source for vertical movement of a needle bar, and a control device that controls the sewing machine motor based on the detection result by the detection portion and performs control to maintain a constant stitch pitch. The control device lengthens a period for obtaining an output of the detection portion when the movement amount of the workpiece per unit time based on the detection result by the detection portion is decreased, and shortens the period for obtaining the output of the detection portion when the movement amount of the workpiece per unit time based on the detection result by the detection portion is increased.
