[0002]

2. Description of the Related Art For example, a railway ticket, a cash dispenser for automatic deposit payment at a bank, a parking ticket, a unit-type winning voting ticket, a telephone card, etc., have a magnetic recording system for inputting and outputting information. Is increasing.

A magnetic head and a thermal head for printing incorporated in a system for inputting and outputting information by a magnetic recording method, and a card-type magnetic recording medium and a heat-sensitive destruction print layer repeatedly fold. Then, the surface of the magnetic recording medium and the heat-sensitive destruction printing layer are worn to generate shavings, which adhere to the magnetic head and the thermal head for printing together with dust and foreign matter in the air, thereby causing incorrect input / output of information. This causes a malfunction of the system, or a printing defect or a stain on the surface of the magnetic recording card.

For this purpose, for example, in order to remove dust and foreign matter adhering to a magnetic head, a printing thermal head, a guide roll, and the like of an automatic ticket gate at a station, the automatic ticket gate is stopped, disassembled, and impregnated with a solvent. He had wiped it off with a rag and a cleaning swab.
