Claims

[Scope of utility model registration request]

a platen, a pinch roller parallel to the platen, a biasing means for biasing a roller shaft holding the pinch roller toward the platen, and a pressing force for pressing one end of the roller shaft in a direction opposite to the biasing direction. gears attached to both ends of the roller shaft, and racks disposed along the biasing direction of the roller shaft and meshed with the gears, the roller shaft and each gear being connected to each other. A pinch roller contact/separation device for a printing machine characterized by being connected with play in the rotational direction.
