In summary, the above-mentioned determining means (see fifth step) determines whether the card is a high coercive force card or a low coercive force card based on the card type data read by the above-mentioned reading means (see second step 22). Based on this determination result, the above-mentioned low-speed switching means (
(see step 6) switches the card conveyance speed to V2, which is lower than when writing to a low coercive force card.
