Abstract: In a facsimile receiver access to the paper supply roll and other internal elements is facilitated by supporting the guide roller, printing bar and presser-roller on a chassis that is pivotable around the axis of the supply roll from a first position in which the paper web is held against the guide roller between the printing drum and the printing bar and between the drive roller and presser-roller, and a second position wherein the guide roller and the pressure-roller as well as the printing bar are positioned remote from said drum and said supply roll.

Abstract: In a facsimile receiver wherein the printing bar is mounted for reciprocal movement between an operative position against the drum carrying the printing helix and an inactive position remote therefrom, means is provided for automatically displacing the printing bar toward its operative position upon rotation of said drum. In this regard a mechanical locking means is included for maintaining said printing bar in its operative position and a release mechanism serves to release the printing bar upon termination of the printing operation.
