PURPOSE:To perform the control properly and easily over the conveyance speed of mobile members, by controlling the voltage to impress a pulse motor and by changing the rotating speed of the pulse motor. CONSTITUTION:The voltage to be impressed to a pulse motor is controlled by voltage switching signals from a controller with transistors T1 and T2 switched ON and OFF and the rotating speed of the pulse motor is forced to change. When mobile members are moved in high speed, the transistor T1 is switched ON, the transistor T2 switched OFF and the voltage V1 is impressed to the pulse motor (where V1>V2). When the mobile members are moved in low speed, the transistor T1 is switched OFF, the transistor T2 switched ON and the voltage V2 is impressed to the pulse motor. |
