Abstract

The information display apparatus includes a sheet display section; a mechanical mechanism that moves the display section, and switches a state of the display section between a deployment state in which a display space is formed and a non-deployment state in which the display space is not formed; a motion sensor that detects a motion of the display section; and a controller that calculates, from data of the detection performed by the motion sensor, at least motion information other than a component related to the movement of the display section that is performed by the mechanical mechanism, and determines an anomaly.

First claim

The invention claimed is:

1. An information display apparatus, comprising:
a sheet display section;
a mechanical mechanism that moves the display section, and switches a state of the display section between a deployment state in which a display space is formed and a non-deployment state in which the display space is not formed;
a motion sensor that detects a motion of the display section; and
a controller that calculates, from data of the detection performed by the motion sensor, at least motion information other than a component related to the movement of the display section that is performed by the mechanical mechanism, and determines an anomaly.

2. The information display apparatus according to claim 1 , wherein
the sheet display section is plastically deformable, and
the mechanical mechanism is configured to take up the display section from a side of an end of the display section, and to move the display section.

3. The information display apparatus according to claim 2 , wherein
the controller is configured to stop the movement of the display section that is performed by the mechanical mechanism when the controller determines the anomaly during the movement of the display section that is performed by the mechanical mechanism.

4. The information display apparatus according to claim 3 , wherein
the motion sensor is a sensor that detects at least one of acceleration or an angular velocity.

5. The information display apparatus according to claim 4 , wherein
the controller is configured to control sensitivity of the motion sensor according to an operation state of the mechanical mechanism.

6. The information display apparatus according to claim 5 , wherein
the controller is configured to set the sensitivity of the motion sensor to be lower during the movement of the display section that is performed by the mechanical mechanism than when the display section is not being moved.

7. The information display apparatus according to claim 4 , wherein
the controller is configured to determine the anomaly with respect to data obtained by removing a component of a frequency of oscillation of the mechanical mechanism from the data of the detection performed by the motion sensor.

8. The information display apparatus according to claim 4 , wherein
the controller is configured to stop determining the anomaly when the movement of the display section that is performed by the mechanical mechanism is started and to stop determining the anomaly when the movement of the display section that is performed by the mechanical mechanism is stopped.

9. The information display apparatus according to claim 3 , wherein
the controller is configured to turn the display section off when the controller determines the anomaly in a state in which the display section is on.

10. The information display apparatus according to claim 3 , wherein
the controller is configured to determine the anomaly when the display section is in the deployment state and when the controller detects an external tension force exerted in a direction in which the display section is moved such that the state of the display section is shifted from the non-deployment state to the deployment state.

11. The information display apparatus according to claim 10 , wherein
the controller is configured to detect the tension force on a basis of an amount of reverse rotation of a motor of the mechanical mechanism.

12. A method for controlling an information display apparatus that is capable of moving a sheet display section and of switching a state of the display section between a deployment state in which a display space is formed and a non-deployment state in which the display space is not formed, the method comprising:
detecting, by a motion sensor, a motion of the display section;
calculating, from data of the detection performed by the motion sensor, at least motion information other than a component related to the movement of the display section that is performed by the mechanical mechanism; and
determining an anomaly.

13. An information processing apparatus, comprising
a controller that acquires data of detection performed by a motion sensor from an information display apparatus that includes
a sheet display section,
a mechanical mechanism that moves the display section, and switches a state of the display section between a deployment state in which a display space is formed and a non-deployment state in which the display space is not formed, and
the motion sensor detecting a motion of the display section,

the controller calculating, from the acquired detection data, at least motion information other than a component related to the movement of the display section that is performed by the mechanical mechanism, and determining an anomaly.
