Guide roller and transport device comprising several rollers

A roller for guiding a sheet by friction, the roller having:

• a contact surface designed to be in contact with the sheet, the contact surface having a shape of revolution when the roller is at rest,
• a central portion configured to mechanically connect the roller to a rotating drive element, and
• a deformation portion located between the contact surface and the central portion, the deformation portion being configured to deform elastically when the roller guides the sheet by friction,
• wherein the deformation portion comprises:
• at least one cut extending from the contact surface towards the central portion, the at least one cut being arranged such that the deformation portion comprises at least one elastically deformable segment, and
• an outer ring and a plurality of connection members mechanically connecting the central portion and the outer ring, wherein the at least one cut extends through the outer ring, and the outer ring mechanically connects at least two connection members of the plurality of connection members.
