LINEAR MOTOR AND PORTABLE DEVICE INCLUDING THE SAME

摘要

<P>PROBLEM TO BE SOLVED: To provide a linear motor that achieves the thinning. Ž<P>SOLUTION: The linear motor 100 includes: a fixed part 10 having a flat spiral current line 14 (a pair of a planar coil 14a and a planar coil 14b) that is mutually separately arrayed; a movable part 20 having a magnetic-pole face (a surface 20b) facing the current line 14 and provided so as to be movable on the current line 14 along the surface (the array direction) of the current line 14; and each blade spring 30 that biases the movable part 20 in a moving direction when the movable part 20 is reciprocatingly moved. Each blade spring 30 is arranged oppositely to each side face 20a of the movable part 20 at both end parts of the array of the current line 14 so as to sandwich the movable part 20 from both sides of the movable part 20. The width H2 of such a blade spring 30 is in the range of a half to one time of the thickness H1 of the movable part 20. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
