Claims

[Scope of utility model registration request]

An X-axis rail attached to a base, a Y-axis rail that moves along the X-axis rail by an X-axis drive, and a carriage that moves along the Y-axis rail by a Y-axis drive and has a writing instrument. In the X-Y plotter comprising: A pair of guide bodies supported by the other end of the rail, a pair of movable bodies supported by the carriage, and a first meshing part of the timing rotating body engage with the guide bodies and the movable body, respectively. an endless timing belt, the carriage is held stationary when the timing rotors make a first rotation in the same direction, and the carriage is held stationary when the timing rotors make a second rotation in the opposite direction. When the carriage rotates, the carriage moves, and the second meshing portion of the timing rotor is reversibly driven to mesh with the X-axis rail by a drive source attached to the base. As the Y-axis rail moves, the timing rotating body rolls along the second timing belt and rotates the first rotation. A Y-axis drive device for an X-Y plotter, wherein the timing rotating body rotates in the second direction as the second timing belt runs.
