PURPOSE:To prevent larger electric source device for driving, by driving step motors of over 2 pieces in the state of time shearing, without driving these at the same time, when above motors are driven. CONSTITUTION:When control signals S1, S2 are supplied to driving parts 1, 3 in which direct current source for operation V is supplied, driving signal which is pulse is output and step motors 2, 4 are respectively driven, these are not operated at the same time, and these are made to be operated in time shearing state, alternatively. Therefore, since electric source part is enough to have capacity to operate any one of them-step motors 2, 4-, electric source device can be miniturized, and reduction of cost can be intended. |
