<p>PURPOSE:To obtain a magnetic head device for photographic film capable of adjusting the positions of a magnetic head and a pad, and being easily assembled in a main body part. CONSTITUTION:The magnetic head 32 of the magnetic head device 30 is fixed on a supporting plate 36 by using a guid block 38, etc. The pad 34 is arranged in a frame part 40 protrusively formed on the supporting plate 36 and energized toward the magnetic head 32 by a spring 42. This magnetic head device 30 is assembled in the main body by previously adjusting the position of the head 32 with respect to the pad 34 by using the guide block 38, etc., and fixing the head 32 at an optimum position where the leading abutting part 32A of the head 32 abuts on the pad 34 by optimum pressing force. Then, the magnetic head device 30 is assembled in the main body of a film image input device. Since a substance unitized after attaching the head 32 and the pad 34 in the supporting plate 36 is assembled, the head 32 and the pad 34 are assembled in the main body through one operation.</p> |
