A shutter mechanism of a card reader including a shutter part for opening/closing a card path through which a card is transferred. The shutter part includes: a closing part for closing the card path; a card contacting section, which contacts an end part of the card inserted into the card path, located at a further frontward position from the closing part in a direction X1; and shaft sections, having their rotation axis in a direction Y, for supporting the closing part and the card contacting section so as to keep them rotatable. The closing part and the shaft sections are located at their corresponding positions that are displaced from each other in a direction X. The closing part and the card contacting section rotate on the shaft sections to open the card path, when the end part of the card contacts with the card contacting section.
