Abstract

An image display device according to the embodiment includes a display screen which is arranged on one surface of a housing and displays a page image using a display mechanism in which scanning can be optically performed in a copy machine; and a control unit which switches a page image displayed on the display screen among the plurality of page images set as a scanning target according to an operation input of a user with respect to an operation input unit which is arranged on the other surface of the housing.

Claims

1. An image display device comprising:

a display screen which is arranged on one surface of a housing and displays a page image using a display mechanism in which scanning can be optically performed in a copy machine; and

a control unit which switches a page image displayed on the display screen among the plurality of page images set as a scanning target according to an operation input of a user with respect to an operation input unit which is arranged on the other surface of the housing.

2. The device according to claim 1,

wherein the operation input unit is a touch panel which receives the operation input of the user.

3. The device according to claim 1,

wherein a physical key which receives the operation input of the user.

4. An image display device comprising:

a display screen which displays a page image using a display mechanism in which scanning can be optically performed in a copy machine; and

a control unit which switches a page image displayed on the display screen from a first page image among a plurality of page images set as scanning target to a second page image among a plurality of page images set as scanning target, when an optical sensor detects brightness of a predetermined threshold value or more, the optical sensor which is arranged at the periphery of the display screen on a plane including the display screen.
