thermal printer

Abstract

Abstract PURPOSE:To make a thermal printer possible to print at high speed by improving a preheating efficiency by composing of a transfer head adjacently equipped to a magnetic substance and a platen consisting of a good electric conductor plate attached onto a magnetic pole of a magnetic substance to which an alternating magnetic field is applied. CONSTITUTION:Applying an alternating magnetic field onto the C-shaped magnetic body 3 equipped on a platen 6, generating a magnetic field loop between the magnetic body 3 and a magnetic body 1 adjacently equipped to a transfer head 2, by which preheating of a transfer layer of a transfer media 9 located immediately below the transfer head 2 by utilizing heat generated by eddy-current caused by magnetic flux change through a good electric conductor plate 5 which is located immediately below the transfer head 2 and forms the top surface of the platen 6 is accomplished. Accordingly, less temperature change of the transfer head is available at the time of recording, so that a high speed printing can be obtained as well as durability of the transfer head can be improved. EFFECT:Because of utilizing a heat generation of a magnetic field, it is easy to make an apparatus smaller, and it is also easy to thermally control of preheating a transfer layer.
