PRINTING DEVICE FOR SCIENTIFIC EXPERIMENT WHICH VISUALLY EXPRESSES PRINCIPLES ABOUT ELECTRIC CHARGE AND ELECTRIC CHARGING HEAT

摘要

PURPOSE: A printing device for scientific experiment is provided to visually understand a contact process of a toner and a drum and to visually express principles about electric charge and electric charging heat.;CONSTITUTION: A first storing unit(10) loads a toner member(11). An electrification panel(20) applies electric repulsion of a toner member which drops from the first storing unit. A drum(30) selectively attaches the toner member through the electrification panel. A paper member(40) transcribes the toner member selectively attached to the drum. A supporter supports the first storing unit on the upper side.;COPYRIGHT KIPO 2013
