Abstract

A display unit is present in a space different from an input and output screen displayed in a three-dimensional space, and a control unit displays the input and output screen as an optical image formation of light progressing in a direction of a user so that no one other than the user is able to photograph the input and output screen.

Claims

1. 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; and

a control unit that performs predetermined control,

wherein the display unit is present in a space different from the input and output screen displayed in the three-dimensional space, and

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 no one other than the user is able to photograph the input and output screen.

2. The input and output device according to claim 1, further comprising:

an input detection sensor that detects an air operation to the input and output screen by the user,

wherein the control unit displays a current image of the input and output screen on the display unit, and updates a display content of the display unit on the basis of an input signal from the input detection sensor.

3. The input and output device according to claim 1, further comprising:

a destruction action detection mechanism that detects a destruction action from an outside,

wherein the control unit automatically erases confidential information stored in an inside in a case in which the destruction action detection mechanism detects the destruction action.

4. The input and output device according to claim 3, wherein the destruction action detection mechanism comprises:

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 the 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

a third conductive medium that connects the protection mechanism to the control unit.

5. The input and output device according to claim 4, wherein, in a case in which the display unit is not in contact with the first conductive material or the connection between the display unit and the first conductive medium is disconnected, the control unit determines that the display unit is removed, and in a case in which the destruction action is detected, the control unit automatically erases the confidential information stored in the inside as correspondence to the detection of the destruction action.

6. The input and output device according to claim 4, wherein, in a case in which the input detection sensor is not in contact with the second conductive material or the connection between the input detection sensor and the second conductive medium is disconnected, the control unit determines that the input detection sensor is removed, and in a case in which the destruction action is detected, the control unit automatically erases the confidential information stored in the inside as correspondence to the detection of the destruction action.

7. The input and output device according to claim 4, wherein, in a case in which the connection between the protection mechanism and the third conductive medium is disconnected, the control unit determines that the protection mechanism is removed, and in a case in which the destruction action is detected, the control unit automatically erases the confidential information stored in the inside as correspondence to the detection of the destruction action.

8. The input and output device according to claim 1, further comprising:

a detection device that detects a face of the user; and

a rotation mechanism that rotates the input and output device so that an image formation position of the input and output screen is directed to the face of the user, on the basis of the face of the user that is detected by the detection device.

9. The input and output device according to claim 1, further comprising:

a camera disposed at a rear of the input and output screen and photographing the user from the rear of the input and output screen without being affected by the input and output screen.

10. An automatic transaction device that performs a transaction according to an input of password information of the user, the automatic transaction device comprising:

the input and output device according to claim 1; and

a user operation unit disposed on a rear side of the input and output screen displayed in the air,

wherein the input and output screen has a keyboard arrangement for inputting the password information, an arrangement of the keyboard arrangement is able to be randomly changed for each display in the input and output screen with respect to the input and output screen, and

operations of inserting and extracting a bill, a card, and a statement slip are possible through a bill opening, a statement slip opening, and a card opening by penetrating the input and output screen, on a state in which the input and output screen is displayed in the air.
