Abstract: A sewing machine includes a mounting adaptor, a memory, an imager, and a processor. The mounting adaptor may be mounted with an embroidery frame. The memory may store frame rotation data. The frame rotation data indicate a setting angle which is a predetermined rotation angle of the frame with respect to the outer frame. The imager may image an area including the embroidery frame mounted on the mounting adaptor. The processor may control the sewing machine to detect a marker provided on at least one of the embroidery frame and the work cloth based on the image, determine a rotation angle of the frame with respect to the outer frame based on the detected marker, and control the driver to adjust a rotation of the frame based on the determined rotation angle and the frame rotation data.

Abstract: An upper feed device is configured to be arranged above a bed of a sewing machine and feed a work cloth. The upper feed device includes a feed portion, a mechanism arrangement portion, and a drive portion. The feed portion includes a first feed mechanism and a second feed mechanism and is configured to feed the work cloth in a feed direction. The first feed mechanism and the second feed mechanism are arranged side by side in a first direction, which is parallel to a top surface of the bed and orthogonal to the feed direction. The mechanism arrangement portion is configured to arrange the first feed mechanism and the second feed mechanism in different positions in a second direction, which is orthogonal to the top surface of the bed. The drive portion is configured to drive the first feed mechanism and the second feed mechanism in synchronization.

Abstract: An embroidery frame comprises an inner frame, wherein the inner frame is a circular form. The embroidery frame comprises a middle frame which is configured to be detachably attachable to a radial outside of the inner frame. The middle frame is a circular form. The embroidery frame comprises an outer frame which is configured to rotatably hold the middle frame, wherein the outer frame is a circular form, and the outer frame is configured to be detachably attachable to a radial outside of the middle frame. The embroidery frame comprises a grip portion which is provided to the middle frame.

Abstract: A sewing machine includes a first drive portion, a switching portion, a second drive portion, a control portion, and a memory. The first drive portion is configured to drive to feed, in a first direction, a work cloth. The switching portion is configured to switch a position of the first drive portion. The second drive portion is configured to drive to feed the work cloth. The memory is configured to store computer-readable instructions that instruct the sewing machine to execute steps of driving the first drive portion in the first position in a case where the second drive portion drives to feed the work cloth in the first direction and switching the position of the first drive portion to the second position in a case where the second drive portion drives to feed the work cloth in a second direction, based on the sewing data.

Abstract: An upper feed device includes a mounting portion, a feed mechanism, a drive portion, and a connecting portion. The mounting portion is configured to mount the upper feed device to a presser bar of a sewing machine. The feed mechanism is configured to feed a work cloth. The drive portion is configured to drive the feed mechanism. The connecting portion is configured to electrically connect the drive portion to a control portion of the sewing machine.

Abstract: An embroidery frame comprises an inner frame, wherein the inner frame is a circular form. The embroidery frame comprises a middle frame configured to be detachably attachable to the inner frame, wherein the middle frame is a circular form, an inside diameter of the middle frame is longer than an outside diameter of the inner frame, and the inner frame is configured to be mountable in the middle frame. The embroidery frame comprises an outer frame configured to rotatably hold the middle frame, wherein the outer frame is a circular form, an inside diameter of the outer frame is longer than an outer outside diameter of the middle frame, and the middle frame is configured to be mountable in the outer frame. The embroidery frame comprises an engaging portion configured to cause the middle frame to engage with the outer frame at a predetermined rotation angle.

Abstract: A sewing machine may comprise a mounting portion configured to be mounted with an embroidery frame comprising a frame and an outer frame. The sewing machine may also comprise an image capturing device configured to capture an image including the embroidery frame mounted on the mounting portion. The sewing machine may further comprise a processor configured to execute instructions, and a memory. The memory may be configured to store computer-readable instructions that instruct the sewing machine to execute steps comprising identifying a mark from the captured image, wherein the mark is provided on the embroidery frame or on a work cloth held by the embroidery frame, determining a rotation angle of the frame with respect to the outer frame based on the identified mark, and notifying rotation information based on the determined rotation angle. The rotation information may be information for adjusting the rotation angle to a specified rotation angle.
