Patent abstract

To record images accurately regardless of rigidity and size of a recording medium, each rear end clamp has a clamp rubber element for engaging a variable margin of the recording medium mounted peripherally of the recording drum. The margin is varied according to the rigidity of the recording medium. The margin is enlarged when the recording medium is highly rigid, and reduced when the recording medium is low in rigidity.
