PURPOSE:To simplify its structure and to realize size reduction by pressing a doctor blade formed of a magnetic member against a nonmagnetic sleeve with the magnetic force of magnets. CONSTITUTION:The cylindrical sleeve 7 is fitted around a holding shaft 6 which has magnets 3-5 embedded in its peripheral surface and the doctor blade 8 which extends in parallel to the axis of rotation of the sleeve 7 and is made of a magnetic material is mounted at the top of the sleeve 7 in a free upward/ downward movable state. Consequently, the blade 8 is pressed against the sleeve 7 with the magnetic force of the magnets 3-5 without using any spring to simplify the structure and realize the size reduction. |
