An information retrieval device having an insertion slot for inserting a medium having data to be retrieved includes an input unit for sending a signal upon accepting an input, an eject unit for ejecting the medium in the insertion slot and a control unit for controlling the eject unit upon receiving the signal from the input unit after an ejection instruction is accepted by the input unit. The signal to the control unit from the input unit after the ejection instruction on the input unit establishes an ejection prohibition control with the eject unit for prohibiting media ejection operation of the eject unit while an ejection prohibition state of the eject unit is brought into effect by using the input unit.
