PURPOSE:To facilitate adjustment and to reduce the production by attaching the light emitting element which detects the light index hole formed on the magnetic disc and adjust the relative position of magnetic head directly on the printed circuit board, and by forming the terminal part so that it may vibrate freely. CONSTITUTION:A light emitting element 21 of which a terminal part 31 is formed in advance in U-shape is directly attached to a printed board 9, and by utilizing the twisting part vertical against the light emitting element 21 out of the U-shaped terminal 31, the light emitting element itself is made to move freely directly towards the arrow direction (b). Thus, since the emitting element is directly moved, the adjustment can be done easily, and part number is reduced in manufacturing, and as there is not joints of connectors, the manufacturing cost can be reduced. |
