ABSTRACT:
The present invention relates to a two-dimensional motion producing apparatus for converting rotation of an input shaft to a two-dimensional motion in an X-direction of an output member and in an Y-direction orthogonal thereto. This apparatus of the present invention is constituted by an input shaft being input a rotational motion; an output member provided movably in a two-dimensional direction; a first guide groove elongated in the X-direction on the output member; a second and a third guide grooves elongated in the Y-direction spaced apart from each other on the output member; a first, a second and a third rocking arms engaged in the first guide groove and the second and third guide grooves respectively through engaging members; a first rocking conversion mechanism for converting the rotation of the input shaft into the rocking motion of the first rocking arm; and a second and a third rocking conversion mechanisms for converting the rotation of the input shaft into the rocking motions in synchronism with each other of the second and third rocking arms. The number of constituent parts for producing the motion can be reduced, whereby the durability of the two-dimensional motion producing apparatus can be materially enhanced.
