A scratch card printer has a conveying section to convey a card, for example, by a plurality of conveying roller pairs, a first printing mechanism to have a thermal head, printing control means to control a printing head of the first printing mechanism to allow information, to be printed on a card, a second printing mechanism configured to have a thermal head located more on a downstream side in a direction of conveying of the card by the conveying section than the first printing mechanism, and a thermal transfer control section which, in order to cover the information printed by the first printing mechanism, controls the thermal head of the second printing mechanism to allow an ink to be transferred to the card from a thermal transfer ribbon for concealment.
