a control unit for controlling the eject unit upon receiving the signal from the input unit after an ejection instruction
is accepted as an input by the input unit,
a display screen for displaying an eject button area; and
a touch panel disposed on the display screen for detecting an operation, wherein

unit causes the control unit to establish an ejection prohibition control with the eject unit for prohibiting a media ejection
operation of the eject unit,
the touch panel is used as a part of the input unit,
the media ejection operation of the eject unit is permitted when the control unit detects an operation in the eject button
area on the touch panel and the ejection prohibition control has not been established, and
