PROBLEM TO BE SOLVED: To easily control two dimensional plane scanning with simple constitution, to continuously use it, to make it excellent for positional reproducibility and to make possible utilizing it in many fields by moving a function element set-up part provided on a position shifted from its rotational center through a planet gear mechanism on a two-dimensional plane in a picture drawn with a single stroke of the brush with rotation of a motor. SOLUTION: A planet gear 10 is provided with the rotational center 11 on the position existing upward a driven gear 6 and properly parting from its rotational center 7, and is rotated while always being inscribed on a sun gear 9. Then, the function element set-up part 12 is provided on the position existing upward the planet gear 10 and properly parting from the rotational center 11. Then, when a driving gear 5 is rotated once by a pulse motor 2, the planet gear 10 is rotated on its axis by the prescribed number of revolution while being inscribed on the sun gear 9, and is revolved once to be returned to the original position. The function element set-up part 12 is moved on the two-dimensional plane in the picture drawn with a single stroke of the brush according to the revolution. Thus, the two-dimensional plane is scanned by the function element set-up part 12. |
