Abstract: A movable divider wall means is resiliently supported to extend through a slot opening in a bottom wall and into contact with the top wall so as to define between one of its faces and one of the edges of a channel guide for documents an effective guide for documents of a narrower width defined by the wall and the opposed channel wall. The movable wall has a tapered top edge which tapers from a widely spaced leading edge to the flat top of the movable wall which abuts the top wall and is held into the top wall by resilient means. Documents of greater width may be inserted over the movable wall and passing documents will urge the movable wall downward to displace it and allow their passage. Guide means is preferably provided to direct documents of the second narrower width into the channel at a position after the beginning of the movable wall and from above the movable wall so that they do not tend to move the wall out of its position as they are introduced.

Abstract: A thermal printer provides first and second sub-frames pivotally supported on a main frame to provide access to a dot resistance heater for cleaning and easy removal of the respective structures. Each structure is releasably fixed in operating position in which a resilient drive roller on the second sub-frame presses the thermally sensitive paper against the printer head. The same roller is driven by a motor on the second sub-frame and moves the paper along the paper path by friction drive. The paper moves between a fixed and rotatable knife on the second sub-frame actuated by crank and linkage connection to the core of a solenoid whose winding is fixed on the main frame. A curved guide plate directs the paper toward an opening and into a surface which imposes an S curve on the paper. The S curve allows enlargement of a storage loop in the paper in case the opening is blocked. suThe present invention relates to a thermal printer for the rapid production of tickets, or the like.
