Abstract: The invention is a coin receiving mechanism having a foreign object release device for use with a coin receiving machine having a coin acceptor/counter device. The invention has a pair of hinged coin chute walls with planar sections arranged in a zigzag manner which define the coin path. The coin chute walls also have a section angled from the zigzagged sections. A cam member is connected by linking arms to the coin chute walls. A coin return lever on the outline of the machine is connected to a drive arm inside the machine. When turned, the coin return lever turns the cam member and causes the coin chute walls to flip open and eject any foreign objects contained therebetween. The drive arm is connected to the coin return lever through a clutch mechanism.

Abstract: An envelope feeder which can be mounted on a printer having a rotatable platen and a printing head for automatically feeding, printing and stacking envelopes is disclosed. It has a blank envelope feeding hopper from which blank envelopes are extracted one at a time and fed by a transporting roll and belt mechanism to the printer platen for printing. The position of the envelope is sensed when it reaches the printer platen and the transporting mechanism stopped for printing of the envelope by the printing head. After printing is completed, the transporting mechanism is reactivated to deliver the printed envelope to an envelope receiving hopper for stacking in sequence with other printed envelopes.

Abstract: A printer reel-over-reel ribbon cartridge having a supply reel located above a take-up reel on the same shaft has a driven stretched elastic endless belt engaging the outer surface of the ribbon on the take-up reel for moving the ribbon from the supply reel to the take-up reel.

Abstract: A printer having a platen mounted on a platen shaft and a line indexing driving gear includes releasable coupling means selectively coupling the platen shaft and driving gear for printer controlled or manual indexing of the platen. It includes an external clutch member rotatably mounted on the shaft and axially moveable therealong, an internal clutch member fixedly mounted on the shaft outwardly of the external clutch member and having on its inner end an external cone clutch element normally engaged with the internal clutch element and a manual clutch disengaging member mounted for axial movement on the shaft outwardly of the internal clutch member.

Abstract: A printer feeding and stacking mechanism for feeding a printer selectively with individual sheets of paper from one of two feeding hoppers holding stacks of individual sheets and sequentially depositing the typed sheets in a stacking hopper. The device features a selectively operable feeding mechanism mounted between the two feeding hoppers; mechanism for moving the feeding hopper walls between operating and loading positions; and mechanism for sequentially stacking the printed sheets into the stacking hopper.

Abstract: A printer is disclosed which has an adjustable support for the print head assembly, either or both for changing the spacing between the print head and paper supporting surface to accommodate multiple sheets of paper and to facilitate paper and ribbon changing and for changing the vertical position of the print head into one of two or more discrete positions to effectively at least double the number of dot positions available for printing from the print head wire array.
