Abstract

The invention provides a sewing machine which can arrange one of fixed rails extending along orthogonal directions under a lower shaft and can sufficiently ensure the installation space for a component supporting the other fixed rail above the lower shaft. An X-axis fixed rail is fixed under the lower shaft. An X-axis moving component has a convex shape which supports a fixed table above lower shaft by legs. The X-axis moving component can be kept away from the lower shaft. A Y-axis fixed rail is shorter than the X-axis fixed rail. The Y-axis fixed rail is supported on an upper surface of the X-axis moving component. According to the invention, the X-axis moving component can be miniaturized, thereby reliably ensuring the installation space.

Description

technical field [0001] The present invention relates to a sewing machine. Background technique [0002] The sewing machine includes a cloth feeding drive. In order to form desired stitches in the cloth, the cloth feed driving device moves the cloth in the X-axis direction and the Y-axis direction. Japanese Patent No. 3592379 discloses an XY feeding drive device of a sewing machine. The X-Y feeding drive device includes a pair of Y-axis fixed rails, a Y-axis moving component, a pair of X-axis fixed rails, an X-axis moving component, and a press table. A pair of Y-axis fixed rails are parallel to the lower shaft of the sewing machine and arranged below the lower shaft. The Y-axis moving member can move back and forth along the pair of Y-axis fixed rails. The X-axis fixed rail is fixed on the upper surface of the Y-axis moving member. The X-axis fixed rail is located between the lower shaft and the needle plate, and extends along a direction perpendicular to the Y-axis fix...
