Abstract

An information distribution system that includes an information reading apparatus reading out data distributed from an information medium and an information display apparatus having an information acquisition unit for acquiring the data distributed from said information reading apparatus, a display for displaying the data acquired by said information acquisition unit, and a display limitation unit for imposing display limitations on the data acquired by said information acquisition unit according to the state of connection between said information reading apparatus and the information display apparatus.

Claims

1. An information distribution system comprising:

an information reading apparatus reading out data distributed from an information medium; and

an information display apparatus having an information acquisition unit for acquiring the data distributed from said information reading apparatus, a display for displaying the data acquired by said information acquisition unit, and a display limitation unit for imposing display limitations on the data acquired by said information acquisition unit according to the state of connection between said information reading apparatus and the information display apparatus.

2. The information distribution system as set forth in claim 1, wherein said display limitation unit imposes severer display limitations in cases where said information reading apparatus is in a non-connected state with the information display apparatus than in cases where said information reading apparatus is in a directly-connected state with the information display apparatus.

3. The information distribution system as set forth in claim 2, wherein said information reading apparatus optically reads out image data from an image display medium, said information acquisition unit acquires image data from said information reading apparatus, said display limitation unit permits this image data to be displayed by said display only for a period from a reference point in time set for each piece of image data acquired by said information acquisition unit until a predetermined time limit is elapsed when said information reading apparatus is in a non-connected state with the relevant information display apparatus, and said information display apparatus further has a deletion unit for deleting this image data from a memory area of the relevant information display apparatus when the predetermined time limit is elapsed from the reference point in time set for each piece of image data acquired by said information acquisition unit.

4. The information distribution system as set forth in claim 2, wherein said information reading apparatus optically reads out image data from an image display medium, said information acquisition unit acquires image data from said information reading apparatus, and said display limitation unit permits this image data to be displayed by said display only when there exists the relevant information display apparatus within a restricted area set with the position of said information reading apparatus as a reference in cases where said information reading apparatus is in a non-connected state with the relevant information display apparatus.

5. An information distribution system comprising:

an information reading apparatus reading out data from an information medium; and

an information display apparatus having an information acquisition unit for acquiring the data read by said information reading apparatus, an authentication setting unit for carrying out setting processing of authentication information relevant to the data acquired by said information acquisition unit only when said information reading apparatus is in a state of connection with the relevant information display apparatus, a display for displaying the data acquired by said information acquisition unit, an authentication unit for carrying out authentication processing on the basis of the authentication information set by said authentication setting unit, and a display limitation unit for permitting the data to be displayed or inhibiting the data from being displayed by said display according to the result of authentication by said authentication unit.

6. An information display apparatus comprising:

an information acquisition unit for acquiring the data distributed from external devices;

a display for displaying the data acquired by said information acquisition unit; and

a display limitation unit for imposing display limitations on the data acquired by said information acquisition unit according to the state of connection between said external devices and the relevant information display apparatus.

7. An information management method for managing data distributed from an information reading apparatus to an information display apparatus, comprising:

a step that the information reading apparatus reads out the data distributed from the information medium;

a step that the information display apparatus acquires the data distributed from said information reading apparatus; and

a step that the information display apparatus imposes display limitations on the acquired data according to the state of connection between said information reading apparatus and the information display apparatus.

8. A computer readable medium storing a program causing a computer to execute a process comprising:

imposing display limitations on the data acquired from an external device according to the state of connection between said external device and said computer.
