Abstract

PURPOSE: To obtain a typewriter having good resolution and enabling precise typewriting by a method wherein an light image permeating through a negative dial is irradiated to a photoinduced discharging thermoplastic ink and, further, dielectric heating is carried out by high frequency electric current to transfer said light image to a typewriting paper.
CONSTITUTION: A dial 7 made of glass or a transparent resin having many negative letters arranged thereon is moved to position and optical letter on a light axis of an objective lens 8 and, when a shutter 6 is opened, light emitted from a light source 1 is passed through the dial and projected onto a transfer tape 12 through the objective lens 8, a prism 9 by a projecting lens 10. A dielectric constant of a solid ink on the transfer tape 12 is changed by a light and a dark areas of the light image and a latent image of the letter. Herein, when high frequency voltage is applied between a transparent electrode 11 and an electrode 14, the ink is charged electrically and attracted and transferred onto the typewriting paper 13.
