Abstract (en)
A cloth cutting device (30) of a buttonholing machine (1) includes a knife (32), a knife receiver (31), a moving mechanism (35) which moves the knife (32) or the knife receiver (31), a pulse motor (34) which serves as a drive source of the movement of the knife or the knife receiver, a rotation amount detector (55) which detects a rotation amount of the pulse motor, and a controller (50) which controls the pulse motor. The controller executes a control to switch the movement of the knife or the knife receiver to be low speed on its way, and includes a cutting control means (50c) which controls the pulse motor to stop driving if a deviation determining means determines that the deviation of the pulse motor reaches the set value, and a current control means (50c) which limits, during the low-speed movement, a current value applied to the pulse motor to be lower than that during a high-speed movement.
