ADAPTIVE PRESSURIZATION TYPE 4-DIRECTION MAGNETIC CARD READER-WRITER

摘要

PROBLEM TO BE SOLVED: To provide a magnetic card reader-writer that can read and write independently of the inserting direction of a medium and the top and bottom of a surface and to prevent errors even when deformations such as ends and wrinkles are present. SOLUTION: An adaptive pressurization type 4-direction magnetic card reader-writer is composed of a carrying motor driving a carrying mechanism constituting a carrying surface for carrying the medium; an actuator for which a first magnetic head whose magnetic pole surface is turned upwards and a second magnetic head whose magnetic pole surface is turned downwards are adjacently arranged across the carrying surface, a head press roller rotatable while bringing the medium into press contact is provided on each magnetic head, respective rotary shafts of the head press rollers are attached to pendulous arms and the respective arms are rotated in both directions of rotating them in a direction opposite to the press contact direction of the head press rollers to perform opening and rotating them in the press contact direction to perform pressurization further; and a controller receiving signals from a sensor sensing a traveling position of the medium and the magnetic heads and controlling the activation stoppage and driving direction of the carrying motor and opening and pressurization of the actuator.
