Abstract: An embroidery data generator is configured to generate embroidery data and is provided with a pattern storing unit and a control device. The pattern storing unit is configured to store plural types of pattern data configured for sewing one or more sub-patterns according to a predetermined stitch pattern. The one or more sub-patterns constitutes an embroidery pattern. The control device is configured to randomly extract pattern data configured for sewing the one or more sub-patterns from the plural types of pattern data stored in the pattern storing unit and to assign extracted pattern data to the one or more sub-patterns.

Abstract: An apparatus includes an information obtaining device configured to obtain information representing an optionally designated position on an object, a projector, a processing device, a pattern specifying device and a control device. The control device is configured to cause the apparatus to specify two designated positions on an object based on information obtained by the information obtaining device, to change a size of a specified pattern according to a distance between the specified designated positions, to cause the projector to project a marker onto the object in a size matched with the changed size of the pattern, based on the specified designated positions on the object, to determine a cutting or printing position of the pattern based on the specified designated positions on the object and to control the processing device to perform cutting or printing of the pattern in the changed size at the determined cutting or printing positions.

Abstract: A sewing machine includes a position acquisition device, a projection device, a processor, and a memory. The position acquisition device is configured to acquire information describing at least one designated position, each of the at least one designated position being a position on a sewing workpiece. The projection device is configured to project an image onto the sewing workpiece. The memory is configured to store non-transitory computer-readable instructions that instruct the processor to execute a step that includes specifying the at least one designated position on the sewing workpiece described by the information acquired by the position acquisition device. The memory is also configured to store non-transitory computer-readable instructions that instruct the processor to execute a step that includes causing the projection device to project a visually recognizable marker onto the sewing workpiece, based on the specified at least one designated position.

Abstract: An apparatus includes a processor and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes including acquiring pattern data, specifying an outline of the embroidery pattern based on the pattern data, creating hole data for causing the sewing machine to form a plurality of holes including one or more first holes and one or more second holes, creating first stitch data for causing the sewing machine to sew one or more stitches for the one or more first holes, and creating embroidery data for causing the sewing machine to form one or more first holes, and sew the one or more stitches for the one or more first holes, and causing the sewing machine to form the one or more second holes, before causing the sewing machine to sew an outline pattern.

Abstract: An apparatus includes an information obtaining device configured to obtain information about cutting or printing of an object, a projector configured to be capable of projecting a marker onto the object, and a control device configured to instruct the apparatus to specify a position on the object based on the information obtained by the information obtaining device and to cause the projector to project the marker onto the object based on the specified position on the object.
