Abstract

PURPOSE: To secure the highly reliable read-out by pushing the spherical conductive material into the guide hole when the card passes through the groove, pushing the conductive material against the spring to remove the surface contact with the contact plate and thus securing good surface contact between the hole of the code and the conductive material.
CONSTITUTION: Insulator material 1 contains the groove into which card 9 is inserted plus guide hole 2 provided nearly vertical to the groove, and spherical conductive material 12 is put into hole 2 with part of it projected. Conductive spring 3 is inserted to hole 2, and contact plate 11 contains the hole to match with hole 2. Then conductive material 5 is engaged to the hole of plate 11 by the function of spring 3. Now material 12 is pushed into hole 2 by card 9 when card passes through the groove, and accordingly material 5 is pushed against spring 3 to remove the surface contact with the contact plate. As a result, the surface contact is secured again between material 5 and the contact plate when the code hole of card 9 arrives, thus improving good adhesion as well as to ensure the highly reliable read-out.
