Abstract
A sewing machine comprising: vertical movement actuator that vertically moves the presser bar having a presser foot; a control unit, that controls the vertical movement actuator to selectively execute a first mode or a second mode; a mode switch unit capable of selectively switching between the first mode and the second mode; and the control unit, when switched to the first mode, controls the vertical movement actuator so as to retain the presser foot at a cloth pressing position irrespective of an operational status of a sewing process; and when switched to the second mode, controls the vertical movement actuator so as to retain the presser foot in a slightly lifted position while a sewing operation is ongoing, whereas when the sewing operation is stopped, the presser foot is moved and retained in the cloth pressing position.
Claims8
A sewing machine, comprising:
- a vertical movement actuator that vertically drives a presser bar having a presser foot attached thereto;
- a control unit that controls the vertical movement actuator to selectively execute a first mode or a second mode;
- a mode switch unit capable of selectively switching between the first mode and the second mode;
- and
- the control unit, when switched to the first mode, controls the vertical movement actuator so as to lower the presser foot and retain the presser foot at a cloth pressing position in which a workpiece cloth is pressed irrespective of an operational status of a sewing process;
- and when switched to the second mode, controls the vertical movement actuator so as to retain the presser foot in a slightly lifted position that is elevated from the workpiece cloth by a predetermined small distance while a sewing operation is ongoing, whereas when the sewing operation is stopped, the presser foot is moved and retained in the cloth pressing position.
