Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A sewing machine comprises: a bed; a projector; and a controller configured to cause the projector to project a grid pattern and a stitch pattern towards the bed in a first case, and project the stitch pattern towards the bed and not project the grid pattern towards the bed in a second case. 2. The sewing machine according to claim 1 , wherein the controller is configured to cause the projector to project the grid pattern with a first color and the stitch pattern with a second color that is different from the first color. 3. The sewing machine according to claim 1 , further comprising a feed dog configured to feed a workpiece placed on the bed in a feed direction. 4. The sewing machine according to claim 1 , wherein the first case is a non-sewing period and the second case is a sewing period. 5. The sewing machine according to claim 1 further comprises a presser foot, wherein the controller is configured to cause the projector to project the grid pattern towards the bed so that a portion of the grid pattern is projected onto the presser foot. 6. The sewing machine according to claim 1 further comprises a presser foot, wherein the controller is configured to cause the projector to project the stitch pattern towards the bed so that a portion of the stitch pattern is projected onto the presser foot. 7. A sewing machine control method, comprising: projecting, by a projector of a sewing machine, a grid pattern and a stitch pattern towards a bed of the sewing machine in a first case; and projecting, by the projector of the sewing machine, the stitch pattern towards the bed of the sewing machine without projecting the grid pattern in a second case.
