Claims

[Scope of utility model registration request]

a platen, a drive motor whose drive shaft is orthogonal to the rotation axis of the platen, a helical gear assembled to the rotation shaft of the platen, and a worm gear assembled to the drive shaft of the motor and meshed with the helical gear. and a platen moving mechanism that moves the platen by a predetermined pitch in the axial direction, and the platen is moved by a pressing force acting on the meshing portion of each gear as the platen moves in the axial direction due to the operation of the moving mechanism. A platen drive device for a scanning dot printer that rotates the dot by a predetermined amount prior to printing.
