Abstract
The invention makes it possible to achieve an increased labor efficiency in connecting a stepping motor and a circuit board. It is intended to provide a structure of electrical connections between the stepping motor and the circuit board in which a main motor unit of the same construction can be used regardless of whether the circuit board is located at a front surface or at a rear surface of the stepping motor. In a preferred embodiment of the invention, a circuit board (50) carrying a control circuit is provided on a front surface of a stepping motor (70) from which a drive shaft (711) of the stepping motor (70) projects and first connecting terminals (52) which extend parallel to an axial direction of the drive shaft (711) and connect to the control circuit are provided on the circuit board (50), while a junction board (80) to be electrically connected to the stepping motor (70) is provided on a rear surface of the stepping motor (70), opposite to its front surface from which the drive shaft (711) projects. As the first connecting terminals (52) are inserted into and connected to second connecting terminals (73), which extend parallel to the axial direction of the drive shaft (7…
