PURPOSE:To enable the turning direction to be reversed easily by a method wherein the excitation current in multiple phases generated by a driving circuit part is transferred by selecting a transfer connector to be supplied for a motor part. CONSTITUTION:A driving circuit part A composed of a driving IC provided on a print circuit generates multiple phases a, b, c, d and common phase to be supplied for connectors 1 and 1'. A plug 2 connected to a stepping motor B is selectively inserted into the connector 1 or 1'. Through these procedures, the turning direction can be reversed easily without making any specified logic circuit. |
