发明名称 ANTIMAGNETIC PASSBOOK CASE
摘要 <p>PROBLEM TO BE SOLVED: To provide an antimagnetic passbook case which is not affected by an external magnetic field and is light and can be easily handled. SOLUTION: This antimagnetic passbook case is constituted by partially attaching an antimagnetic plate in a size to cover the whole of a magnetic recording layer adhered on a prescribed position of a paper mount in a condition wrapped by a plastic sheet at a position facing the magnetic recording layer of a stored passbook. The antimagnetic passbook case prevents data recorded in the magnetic recording layer of a passbook stored inside from being made unreadable by effect of an external magnetic field.</p>
