Abstract

La présente invention concerne un stylo électronique. Un stylo électronique selon un mode de réalisation de la présente invention comprend : un boîtier ayant une cavité formée dans une extrémité de celui-ci; une pointe de stylo disposée sur cette extrémité du boîtier à travers la cavité et ayant une extrémité exposée à l'extérieur; un noyau ayant une extrémité couplée à l'autre extrémité de la pointe de stylo; une bobine enroulée autour et entourant le noyau; un premier support ayant une extrémité reliée à l'autre extrémité du noyau; un conducteur élastique ayant une extrémité connectée à l'autre extrémité du premier support; un élément d'espacement ayant une extrémité reliée à l'autre extrémité du conducteur élastique; un diélectrique ayant une extrémité reliée à l'autre extrémité de l'élément d'espacement; et un élément métallique disposé sur l'autre extrémité du diélectrique, l'élément d'espacement ayant une forme annulaire circulaire ou ovale, et une fente étant formée dans une partie de la forme annulaire. Par conséquent, la recouvrance de l'élément d'espacement constituant une partie d'un condensateur peut être rapidement effectuée après achèvement de la compression.
