The sewing system includes a device and a sewing machine including a movement mechanism to move an embroidery frame. The device identifies reference point coordinates representing a position of a reference point provided in a range prescribed by an inner frame of the embroidery frame and transmits the reference point coordinates to the sewing machine. The sewing machine notifies a notification position, using a notification portion, with respect to the range prescribed by the inner frame and acquires a relative movement amount of the embroidery frame with respect to the notification portion, for aligning the notification position and the reference point provided in the range prescribed by the inner frame. The sewing machine decides, on the basis of a relationship between the movement amount and the reference point coordinates, a deviation from a prescribed state of a positional relationship between the inner frame and the movement mechanism.

Sewing machine

A sewing machine acquires a selected pattern that is selected from among a plurality of embroidery patterns. The sewing machine displays a pattern image representing the selected pattern. The sewing machine identifies a specified position indicated by the instruction. The sewing machine determines, when the selected pattern is acquired a plurality of times, whether one of a plurality of the pattern images is displayed at the identified specified position. When it is determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which the pattern image is displayed at the specified position as the editing target. When it is not determined that the pattern image is displayed at the identified specified position, the sewing machine identifies the selected pattern for which a mask region encompassing the selected pattern is set at the specified position as the editing target.

A cutting apparatus includes a moving device configured to move a cutting blade and an object in a first direction and in a second direction differing from the first direction, relative to each other and a control device configured to cause the apparatus to calculate first cutting time lengths required to cut a pattern at a plurality of arrangement angles when an arrangement angle of the pattern relative to the first or second direction is changed by a first unit angle, determine one of the arrangement angles, which is shortest with respect to the first cutting time length or not more than a first threshold, and control the moving device so that the movement of the cutting blade in the first direction and the movement of the object in the second direction are simultaneously executed, with a result that the pattern is cut at the determined arrangement angle.

A sewing machine includes a needle bar, a feed mechanism, a swinging mechanism, a display device, and a control device. The control device determines whether each one of a plurality of sets of sewing data for sewing a pattern is editable, displays on the display device, editable pattern described by the sewing data that has been determined to be editable, and acquires a selection command that selects an object pattern from among the editable pattern. The control device also acquires edit command to edit the selected object pattern, edits object sewing data that are for the object pattern, in accordance with the edit command that has been acquired, and causes the sewing machine to sew the object pattern on a sewing workpiece, based on the edited object sewing data, by operating the feed mechanism that moves the sewing workpiece and the swinging mechanism that swings the needle bar.
