Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
164 words
Electrostatic recording apparatus for electrostatic printing on a continuous sheet of recording paper, said apparatus comprising a recording electrode for recording information on a continuous sheet of recording paper; first means for feeding a continuous sheet of recording paper past said recording electrode at high and low speeds; developing and fixing means for developing and fixing electrostatic latent images imparted to a continuous sheet of recording paper by said recording electrode; second means for feeding a continuous sheet of recording paper past said developing and fixing means at said high and low speeds; and a cutter disposed between said recording electrode and said developing and fixing means and arranged to sever the continuous sheet of recording paper, said first and second means being independently controllable so that said first means can feed a continuous sheet of recording paper at said low speed while said second means feeds the continuous sheet of recording paper severed from the last-mentioned sheet of recording paper at high speed.
Claim 2
Dependent Claim
164 words
Electrostatic recording apparatus for electrostatic printing on a continuous sheet of recording paper, said apparatus comprising a recording electrode for recording information on a continuous sheet of recording paper; first means for feeding a continuous sheet of recording paper past said recording electrode at high and low speeds; developing and fixing means for developing and fixing electrostatic latent images imparted to a continuous sheet of recording paper by said recording electrode; second means for feeding a continuous sheet of recording paper past said developing and fixing means at said high and low speeds; and a cutter disposed between said recording electrode and said developing and fixing means and arranged to sever the continuous sheet of recording paper, said first and second means being independently controllable so that said first means can feed a continuous sheet of recording paper at said low speed while said second means feeds the continuous sheet of recording paper severed from the last-mentioned sheet of recording paper at high speed.
Claim 3
Dependent Claim
39 words
Electrostatic recording apparatus as claimed in claim 1, wherein said first and second means are arranged to operate at the same speed when an unsevered continuous sheet of recording paper is entrained by both said first and second means.
