PURPOSE:To make it possible to obtain a cartridge assembly structure easely, by inserting and fixing a cantilever into a yoke and by tightening the yoke with screws through a spacer. CONSTITUTION:V-shaped grooves 10 and 11 of 90 deg., for exapmple, are installed into a yoke 6, and bar-shaped members 8 and 9 are put into the grooves 10 and 11 in such a way that the end part of the members 8 and 9 are projected from the yoke 6. The bottom of a magnet 12 is fixed to the yoke 6 and the top of the magnet 12 contacts with a horizontal section 16 of an L-shaped yoke made of a magnetic substance 13. At the lower end of a vertical section of the yoke 13, and coils 2 and 3 are set to a cantilever 1 are inserted, respectively, V-shaped notches 14 and 15 of 90 deg., for example, are installed. At both side ends of the bottom part of the vertical section 17 of the yoke 13, tapped holes 18 and 19 for screws 20 and 21 for fixing the yoke 13 are installed. The yoke 13 is fixed to the yoke 6 putting spacers 24 between by the screws 20 and 21. |
