Abstract: A combination bookmark and page prop device having a first elongated arm and a second elongated arm connected, end-to-end by a hinge. A space is created between the respective connected ends of the support arms so that rotation of the support arms in one direction about the hinge results in an abutting relationship between the arms creating a positive stop wherein the respective support arms are positioned at an angular relationship of approximately 80.degree. to 100.degree.. Each support arm is placed upon an opposed page of a bound document to prop it open. The respective support arms can be rotated about the hinge until they are fully extended, end-to-end, to function as a flat bookmark. The support arms can be further rotated about the hinge until the support arms are aligned parallel to one another to form a relatively flat bookmark approximately one-half the length of the fully extended marker. The support arms are constructed from a clear material to allow viewing of printed material through the arms.

Abstract: A device for monitoring paper feed movement in typewriters, printers or other paper-feeding apparatus, e.g. photocopiers wherein paper sheets inserted between a rotatable platen and pressure rollers are driven incident to rotation of the platen. A signal generator has a driving roll of the same size as the pressure rollers and axially aligned therewith which is prevented from being driven by the platen by the interposition of a narrow stationary belt positioned between the platen and drive roller adjacent one end of the platen. When paper is inserted a side edge passes between the belt and the drive roll and movement of the paper incident to platen rotation drives the drive roll of the pulse generator which monitors paper movement. If there is no paper movement due to paper jams or the end of a paper sheet is reached this condition is detected by the absence of pulses at the output of the pulse generator. The absence of pulse sequences serve to shut down the machine.
