Provided is a sewing machine in which a stitching needle and a holding frame holding an article to be sewn are positioned relative to each other based on sewing pattern data defining a plurality of needle drop positions, and sewing is performed in accordance with a sewing pattern. The sewing machine includes: an imager for capturing an image of the holding frame; a position detector for detecting, from the image captured by the imager, the position of an indicator indicating a reference position marked in an object to be imaged; and a corrector which, based on a deviation of a detected position of the indicator detected by the position detector with respect to a regular position defined in advance for the indicator, corrects a plurality of needle drop positions defined in the sewing pattern data.

A stitching system includes a jig capable of joining two shoe parts and capable of being used in an automated stitching machine. The jig includes a lower member capable of being operably coupled to the automated stitching machine and an upper member also capable of being operably coupled to the automated stitching machine. The two shoe parts are held in place between the lower member and the upper member. The lower member, the upper member and the two shoe parts therebetween are moved by the automated stitching machine in accordance with a pattern stored in the automated stitching machine.

A sewing machine determines a pattern from multiple patterns, as a first pattern. The sewing machine generates a projection image including a first image representing a sewing image of the first pattern in a sewing expected size thereof. The sewing machine projects the generated projection image onto a projection area. The sewing machine sews the first pattern on a workpiece in the sewing expected size based on pattern data for the first pattern.

A sewing machine includes: a needle vertical movement mechanism which moves a sewing needle; a moving mechanism which holds a workpiece by a holding frame; an inner presser-foot device which moves an inner presser foot on an upper side of the workpiece held by the holding frame; a control device which controls the moving mechanism based on sewing data in which stitch positions are defined in order in a series of sewing; and a height detector which detects a height of the inner presser foot. The control device lowers the inner presser foot to an upper surface of the workpiece held by the holding frame, detects the height of the inner presser foot by the height detector, and determines suitability of a thickness of the workpiece, at one or plural stitch positions defined in the sewing data before starting the sewing in accordance with the sewing data.
