けるＩＣカードの保護装置。[Scope of Claim for Utility Model Registration] In a reader/writer having an IC card insertion/removal section, the insertion/ejection section is set to a state where the card can be inserted/removed by operating the ejection button. an interrupt generating means that generates an interrupt signal based on a card ejection instruction from the interrupt generating means; and an access control that sets a write-protected state to the card after finishing the access to the card that is currently being executed based on the interrupt signal of the interrupt generating means. 1. A protection device for an IC card in a reader/writer, comprising: a means for protecting an IC card in a reader/writer, and an insertion/removal control means for setting an insertion/ejection section to a card removable state after the access control means sets a write-inhibited state.
