Patent ID: 7505721

Claim:
An image registration device for an image production system comprising a first rotatable element for carrying images of marking substance on its surface, said first rotatable element being provided with a first shaft and a first flange co-axially mounted on the first shaft adjacent the first rotatable element; and a second rotatable element for receiving on its surface images from the first rotatable element, the second rotatable element being mounted axially parallel with the first rotatable element such that, in operation, the second rotatable element is in rolling contact with the first rotatable element, the second rotatable element being provided with a second shaft and a second flange co-axially mounted on the second shaft adjacent the second rotatable element at the corresponding side compared to the mounting of the first flange, wherein the image registration device further comprises: a third rotatable element and pressure exerting means for pressing in operation the third rotatable element with a predetermined pressure in rolling contact with the first flange and the second flange such that one of the first and second rotatable element axially follows the other one, whereby the pressure exciting means presses, in operation, the third rotatable element with a predetermined pressure in an axial direction of the first and second rotatable elements.
