PURPOSE:To easily improve the azimuth accuracy, by providing an adjusting means using a screw, and adjusting a base part and a head part. CONSTITUTION:A head base 4' consists of an arm part 8, a neck part 9, a head part 10 and a base part 11. This base is provided with a height adjusting screw 12 of a magnetic head which is in contact with the lower surface of the head part 10, and an azimuth adjusting screw 13 which is in contact with the lower surface of the arm part 8, the height adjusting screw 12 comes into contacts with the lower surface of the head part 10 at a point G, and the azimuth adjusting screw 13 comes into contact with the lower surface of the arm part 8 at a point H. As a result, the head part 10 is moved in the direction as indicated with an arrow I by the height adjusting screw 12, the arm part 8 is moved in the direction as indicated with an arrow J by the azimuth adjusting screw 13, and fine adjustment can be executed by these 2 screws 12, 13. |
