PROBLEM TO BE SOLVED: To provide a width adjustment mechanism of a substrate carriage device, when changing to a printed board of a type having a different carriage width.SOLUTION: At a change to a printed board P having a larger carriage width (wide printed board), a drive motor 10 is driven to rotate pulleys 11 to 14 through a belt, so that ball screw shafts 19, 20 are rotated by the rotation of the pulleys. Then, ball screw nuts 21, 22 move along the guide bodies 23, 24 to fit to the width dimension of the printed board P, so that a movable chute 3, having fixed ball screw nuts 21, 22, moves to a direction apart from a fixed chute 2. |
