Abstract

PURPOSE: To reduce the generation of interference voltage by uniting a yoke to couple both the disk-shaped rotary yoke and the cam-shaped rotary magnetic pole each other in one body.
CONSTITUTION: A disk-shaped transparent hole is mounted at the center of the substrate 31 jointly used as a yoke and the axis of rotation 35 on which the yoke 34 to magnetically connect the disk-shaped rotary yoke 32 and the cam-shaped rotary magnetic pole 33 each other is formed so as to penetrate into this hole. The stator fixes the permanent magnets 36 and 37 magnetized in the thickness direction to the opposed position which sandwiches the rotary section on the substrate 31 and the stator magnetic poles 40 and 41 around which the pickup coils 38 and 39 are wound are fixed on the permanent magnets 36 and 37. The stator magnetic poles 40 and 41 has their tips at the opposed position sandwiching the rotary magnetic pole section 33 and space between them and the convex section of the rotary magnetic pole section 33 even when it rotates to the position of its tip. The width D of the convex section is smaller than the width thickness W of the stator magnetic poles 40 and 41.
