Title:
MAGNETIC CARD READER
Document Type and Number:
Japanese Patent JP3733193
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To cope with a thin magnetic card by catching a magnetic card between a second driving roll and a retaining roll and performing the control with this catch position as the reference so that a test card and a first retaining roll are separated from each other by a minute distance through a first control tool.
SOLUTION: When a card reader is used for a card whose thickness is about 0.76mm like a magnetic card, a first control tool 31 is controlled to extend a gap W2 between a first driving roll 1 and a first retaining roll 11. When it is used for a this card whose thickness is about 0.2mm like a prepaid card, the first control tool 31 is controlled to reduce the gap W2 between rolls 1 and 11. Thus, accurate magnetic recording is possible even when a thick card as well as a thin card is used, and the card reader can be used for thick cards and thin cards.
