Claims

[Scope of Claim for Utility Model Registration] In a magnetic head moving device that moves a carriage with a magnetic head attached using a PM type or hybrid type stepping motor, contacts other than ground are arranged at positions dividing the circumference into equal angles. A magnetic head moving device characterized in that each winding terminal of a stepping motor and each output terminal of a drive circuit are connected through a connector which is rotated by one division angle and can be connected in different directions. .
