PURPOSE:To put a photodetection fiber in linear reciprocating motion without changing rotational directions of a motor by arranging plural projection fibers opposite to the photodetection fiber fitted atop of a connecting rod. CONSTITUTION:The lower side of the outer circumferential surface of the 1st disk C to be driven is cut into a tooth surface Mb which engages a driving gear Ma driven by the 1st motor M while supported vertically and pivotally. The outer circumferential surfaces of the 2nd disk A and the 3rd disk B are cut into bevel teeth Aa and Ba which engage bevel teeth Ca cut in the upper side of the outer circumferential surface of the 1st disk C, and the 2nd disk A and the 3rd disk B are provided opposite to each other with the 1st disk C between; and those 2nd and 3rd disks A and B rotate by the rotation of the 1st disk C at the same speed in the opposite directions while having the same angle of rotation. The connecting rod pierces laterally both the 2nd and the 3rd disks A and B at 180 deg. out-of-phase positions. Said connecting rod Z has the tip driven by a motor N in linear reciprocating motion while running through an origin on the center prolongation between both disks A and B on the basis of the opposite-directional equal-speed rotations of both facing disks A and B. |
