Input and output device and automatic transaction apparatus

An input and output device comprising:

• a display unit that displays a predetermined image;
• an image formation mechanism unit that causes the image displayed on the display unit to be formed in air as an input and output screen by projecting the image on a three-dimensional space visible to a user;
• a control unit that performs predetermined control;
• and
• a destruction action detector, the destruction action detector comprising
• a first conductive material disposed in the display unit,
• a first conductive medium that connects the first conductive material to the control unit,
• a second conductive material disposed in an input detection sensor,
• a second conductive medium that connects the second conductive material to the control unit,
• a protection mechanism that covers the control unit and includes signal lines attached in a mesh shape, and
• a third conductive medium that connects the protection mechanism to the control unit,
• wherein the detector is configured to detect a destruction action that is at least one of
• the display unit being removed from the first conductive material or disconnected from the first conductive medium,
• the input detection sensor being removed from the second conductive material or disconnected from the second conductive medium,
• the protection mechanism being removed from the control unit, or
• the signal lines of mesh shape being disconnected,
• wherein the control unit, in response to detecting the destruction action, automatically erases confidential information stored in an inside in a case in which the destruction action detector detects the destruction action,
• wherein the display unit is present in a space different from the input and output screen displayed in the three-dimensional space, and
• wherein the control unit displays the input and output screen as an optical image formation of light progressing in a direction of the user so that a position of the optical image formation remains fixed relative to the user so as to be in front of the user when the user faces the display unit, and no one other than the user is able to photograph the input and output screen.
