Ink donor film

Abstract

Abstract PURPOSE:To enable the enhancement of use efficiency, by providing a memory means utilizing a magnetic body storing predetermined information in a non- printing region. CONSTITUTION:The writing of the use information of an ink donor film 10 to a magnetic stripe 11 is performed by magnetizing said nagnetic stripe. That is, when a current (i) is formed to a coil 23b, line of magnetic force is generated in a magnetic core 23a and N, S are formed to both terminals of a head. Next, when the magnetic stripe 11 is placed under the head, said magnetic stripe 11 has S, N generated therein and magnetizes a used part to read information. When information is read, a magnetic core 24a is allowed to approach the magnetic strip 11 to generate induction voltage eV in the coil 24b and this induction voltage is outputted to a control part 25 as a regeneration output signal. Contrarily, no output appears in a non-magnetized part. That is, by the presence or absence of the output of the regeneration output signal of eV, it can be judged whether the ink donor film was used.
