PURPOSE:To decrease the wear of a tap, by giving a shift of the oscillation timing between a pair of oscillating arms to produce a gap between both heads and as a result reducing the relative speed of collision. CONSTITUTION:A pair of oscillating arms 6 and 7 are supported opposite to each other centering on a floppy disk 1 and via a pair of holding cantilever plate springs 4 and 5 which are fixed to a carriage 2 by means of screws 3. The rounded projections 8 and 9 are formed outside the arms 6 and 7 respectively, and a pair of placing plate springs 10 and 11 are fixed to the carriage 2 with the screws 3 to press the projections 8 and 9. The stoppers 12 and 13 are formed to the carriage 2, and the sliding pieces 14 and 15 are formed at the base sides of the arms 6 and 7. The heads 16 and 17 are attached to the plate springs 20 and 21 which are fixed to the inner sides of the arms 6 and 7 via blocks 18 and 19 respectively. These heads are then energized in the approaching direction. The press arms 22 and 23 are attached to the springs 20 and 21. |
