A laser alignment device for a sewing machine and a sewing machine equipped with a laser alignment device. The laser alignment device projects an illuminated alignment guide for aligning a fabric material in a feed path for sewing by a sewing machine needle. The laser alignment device includes a laser, an optical lens to provide a linear laser projection along the feed path, and a power supply to activate the laser alignment device. The laser alignment device is mounted to the head of the sewing machine to permit multi-axial adjustment for alignment of the linear light projection with a desired feed path of the sewing machine.

In a sewing machine, an arm includes, on one side thereof in a first direction, a head. A needle bar is disposed at the head to reciprocally move in a second direction. A feed mechanism feeds a workpiece from one side toward the other side of the head in a third direction. The projection unit disposed at the head projects a projection image toward a bed. The projection unit includes an emitter for projecting image light of the projection image. The photographing unit disposed at the head captures a photographing target. The photographing unit includes an incident portion on which light reflected by the photographing target is incident. The emitter and the incident portion are disposed further toward the one side of the arm in the first direction than the needle bar, and further toward the one side of the head in the third direction than the needle bar.

A hopping foot guide device for use with a longarm quilting machine to guide the longarm machine's hopping foot sewing needle mechanism across material in an intricate pattern without the need to reset at every turn or otherwise move as the stitching progresses, and capable of accurate repetition.

A sewing machine includes a bed, a feed unit, a sewing unit, a projector, and a controller. The projector is configured to project a projection image to the bed. The controller is configured to, where the feed unit and the sewing unit do not perform sewing, execute a first control in which the controller causes the projector to project a first image to the bed, the first image including a first object and a second object, the first object indicating a planned sewing position, the second object indicating a reference position to position the workpiece. The controller is configured to, where the feed unit and the sewing unit perform sewing, execute a second control in which the controller causes the projector to project a second image to the bed, the second image including the first object and not including the second object.

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 guiding tool includes a presser foot, a holder and a gauge. The presser foot includes a bottom wall and a rear support. The bottom wall is formed with a needle-passing hole and with a slit extending from the needle-passing hole to the front end of the bottom wall. The rear support is connected to the rear end of the bottom wall. The holder, attached to a presser bar of the sewing machine, holds the presser foot pivotally about a horizontal axis. The gauge, supported by the rear support to be slidable in parallel to the horizontal axis, includes a ruler plate and a guide portion. The ruler plate has a surface marked with a scale. The guide portion extends from the ruler plate. The ruler plate is disposed above the bottom wall with its surface inclined to become higher as proceeding rearward.
