Abstract: A paper cutting device for use in a printer for cutting off a sheet of recording paper. A first cutter blade is supported on a frame of the device and a second cutter blade pivotably supported on the frame is movable over the first cutter blade to cut off a section of the recording paper. A support member on the frame acts as a fulcrum for the second cutter blade. A drive lever pivots the second cutter blade about the support member towards the first cutter blade to cut off the recording paper. The device is constructed to prevent malfunction of and damage to the device and printer in which it is utilized.

Abstract: In a small printer a common drive mechanism advances two independent paper sheets in unison by a single line spacing or pitch distance during each print cycle. Alternatively the first paper sheet is advanced four pitch distances while the second sheet is advanced one spacing or pitch distance during a print cycle. Or in another alternative action only the second paper sheet is advanced one pitch distance in the print cycle while the first sheet is stationary. Gearing to drive each paper sheet is coaxially but independently mounted. A solenoid plunger translates the gearing which drives the first sheet between a position of engagement with the gears driving the second sheet, and a position of engagement with intermediate gearing which drives the first paper sheet by four spacings.

Abstract: A web-feeding mechanism for a compact printer which can feed at least one web of paper at selectively variable feeding rates is provided. A pair of rotatably driven web feeding rollers is positioned on a first side of the web of paper to be fed, and cooperates with a pair of selectively displaceable idler rollers correspondingly positioned on the other side of the web. The respective feeding rollers are each capable of being driven at a different rotary speed. The respective idler rollers are selectively displaceable between a first position out of engagement with its associated web feeding roller, at which time web feeding by the feeding roller corresponding thereto is prevented, and a second position in engagement with the paper web and the web feeding roller corresponding thereto for feeding the web therebetween at the feeding rate of the feeding roller.
