172 Image forming apparatus and cleaning method US14338801 2014-07-23 US09507311B2 2016-11-29 Masakazu Sone
There is provided an image forming apparatus including a paper feed tray configured to accommodate at least one sheet, a paper feed roller configured to send the sheet from the paper feed tray, and a cleaning member at the paper feed tray, the cleaning member being configured to clean a surface of the paper feed roller. The paper feed tray is movable between a paper feeding position from which the paper feed roller sends the sheet and a cleaning position at which the paper feed roller comes into contact with the cleaning member.
173 Neutralization apparatus and printer having neutralization apparatus US12713964 2010-02-26 US08189024B2 2012-05-29 Takanobu Nishimura; Yukio Asari
The invention provides a neutralization apparatus which simplifies an apparatus composition, lowers an apparatus cost and removes electrical charge effectively from a ribbon-like substance which is charged by stripping, and provides a printer having the neutralization apparatus. The neutralization apparatus neutralizes an ink ribbon. The neutralization apparatus has a conductive roller which is arranged so as to contact the surface of the ink ribbon and a neutralization brush which counters the back of the ink ribbon. A balance of the electrical charge of the surface and the electrical charge of the back of the ink ribbon is broken by electrical discharge caused by the conductive roller. And thereby, the charged voltage of the electrical charge of the back of the ink ribbon becomes large and the neutralization brush remove the electrical charge charged to the back of the ink ribbon effectively.
174 Cleaning roller system and operating method thereof US883433 1997-06-26 US5986683A 1999-11-16 Mitsuru Sawano; Kazuaki Kinjyo; Masatoshi Toda; Tetsuya Murase
A cleaning roller system, which is preferable for use in a printer having a printing head, is disclosed. The cleaning roller system comprises an adhesive roller which is provided on a recording material feeding side relative to a print head, the adhesive roller has adhesive property, and is in contact with a surface of said recording material, and rotates in a direction of transporting said recording material.
175 Image composing apparatus using heat sublimation inks US633072 1996-04-16 US5808652A 1998-09-15 Naoto Iwao
The image composing apparatus of the invention includes an ink medium, a halogen heater for preparatorily heating the ink medium, and a thermal head which heats the ink medium and transfers the heat sublimation ink onto the recording medium. The ink medium has an ink carrier made from a resin on which a heat sublimation ink is dispersed and which is formed on the outer perimeter of a cylindrical axle on which a heat resistant resin layer of polyimid, or similar material, is formed on the surface. The ink maintaining unit temporarily maintains the heat sublimation ink which has sublimed by a preparatory heating using from the halogen heater established inside the axle to move from the ink carrier to the surface layer.
176 Printing apparatus with a printhead having stratified recording electrodes, return electrode and preheating electrode for use with resistive thermal transfer ribbon US594327 1990-10-09 US5079566A 1992-01-07 Takashi Mori
An ink transferring printing mechanism includes an ink sheet having a resistance layer, a conductive layer and an ink layer which are stacked in this order, and a recording head. The recording head has a plurality of recording electrodes arranged in a line, each of which corresponds to a pixel in the image, a preheating electrode and a feedback electrode, each of said recording electrodes being positioned between the preheating electrode and the feedback electrode, at least each of the recording electrodes and the preheating electrode being integrated and stratified. Each of the recording electrodes, the preheating electrode and the feedback electrode are respectively in contact with the resistance layer of the ink sheet. A recording current corresponding to image information is supplied to each of the recording electrodes and a preheating current is supplied to the preheating electrode.
177 Means for preventing electrification of an ink ribbon cassette US894720 1986-08-08 US4738554A 1988-04-19 Akio Tajima
Grounding members are provided on support plates for an ink ribbon cassette, the support plates are secured to a chassis. The support plates and the chassis are both made of electrically conductive material. When an ink ribbon cassette is placed on the support plates, the grounding members contact the ink ribbon to ground static electricity.
178 Apparatus for erasing typewriter tape US3625334D 1969-01-15 US3625334A 1971-12-07 AHN KIE Y
A tape having a smooth surface upon which a low melting point ink has been flowed, has ink reflowed over those portions which have been struck by typewriter keys. To effect a redistribution of the ink on the tape, heat is imparted locally thereto, such heat being applied to the typewriter tape either by conduction or radiation. Alternatively, the ink may be caused to flow freely at ambient temperatures and then be permitted to dry to a film thickness.
