SEWING MACHINE |
| 摘要 |
A sewing machine includes a detection unit configured to detect a moving direction of an object to be processed when the object placed on a sewing machine bed is moved in any direction, a cutting needle having a distal end formed with a blade edge and configured to form a cut in the object, an up-down drive mechanism configured to reciprocate the cutting needle in an up-down direction, a rotational drive mechanism configured to rotate the cutting needle about a rotation axis line of the cutting needle, and a control device configured to control the up-down drive mechanism and the rotational drive mechanism based on a result of detection by the detection unit so that the cutting needle forms the cut in the object while changing an orientation of the blade edge according to the moving direction of the object. |
