Abstract: A sewing machine capable of embroidery sewing includes a plurality types of embroidery frames which hold a workpiece cloth; a carriage that has the embroidery frame detachably attached thereto by sliding the embroidery frame in a predetermined direction; a frame moving unit that moves the carriage in two directions intersecting in a horizontal plane; a control unit that controls the frame moving unit; a detection that detects a type of embroidery frame attached to the carriage; an operation instructing portion that allows a user to instruct movement of the embroidery frame to a predetermined position suitable for attachment/detachment of the embroidery frame, the operation instructing portion outputting a movement instructing signal to the control unit when operated; and a validating unit that validates operation of the operation instructing portion provided that an attachment of a specific type of embroidery frame is detected by the detection mechanism.

Abstract: A sewing machine includes an embroidery stitching data storage storing embroidery stitching data of a plurality of divided patterns with respect to large-size embroidery patterns, a pattern display data storage storing pattern display data for displaying each large-size embroidery pattern in a real image close to an embroidered state, and a display control device reading pattern display data with respect to an appointed large-size embroidery pattern from the pattern display data storage and controls to display an image. The display control device is adapted so that, when each divided pattern constituting the large-size embroidery pattern is subjected to the embroidery stitching, a display is caused to display the pattern display data of the large-size embroidery pattern read from the pattern display data storage and displayed area data indicating the stitching area occupied by each divided pattern in the large-size embroidery pattern in a state being combined with each other.

Abstract: A control unit for controlling an embroidery sewing machine includes an embroidery-data storing portion, a feed-data extracting portion, and a thread-cutting-data adding portion. The embroidery-data storing portion stores embroidery data defining an embroidery pattern sewn by a sewing portion and a workpiece feeding portion. The embroidery data includes stitch data indicating needle drop positions for forming stitches on a workpiece and feed data indicating feed positions for feeding the workpiece. The feed-data extracting portion extracts the feed data from the embroidery data read from the embroidery-data storing portion. The thread-cutting-data adding portion adds thread cutting data immediately prior to the feed data extracted by the feed-data extracting portion. The thread cutting data instructs a thread cutting portion to perform thread cutting.

Abstract: An electronic sewing machine M capable of embroidery stitching is provided with an embroidery frame driving mechanism for driving a embroidery frame based on embroidery stitching data, in the case of a large-size embroidery pattern larger than the embroidery area of the embroidery frame, capable of dividing the pattern into a plurality of divided patterns to perform the embroidery stitching. Included are an embroidery stitching data storage unit that stores embroidery stitching data of a plurality of divided patterns of a plurality of large-size embroidery patterns; a display adapted to display the embroidery patterns etc.

Abstract: A reference image signal level curve V1 and a predetermined coefficient are provisionally stored in a ROM of a main controller. The predetermined coefficient provides a threshold level curve by multiplying by the curve V1. A white color image signal level curve V2 is formed upon reading a white reference surface by optical sensors. The white color image signal level curve V2 is compared with the reference image signal curve V1. If at least a part of the curve V2 is not coincident with at least a part of the curve V1, the curve V1 is multiplied by ?V percent, and this percentage is stored in a RAM. These are performed repeatedly until a part of the curve V2 is coincident with a part of the curve V1 as a result of increase in cumulative ?V percent. Thus, a correction coefficient K is determined based on the cumulative ?V percent to provide a corrected image signal level curve. The corrected image signal level curve is compared with the threshold level curve to obtain a binary image data.
