INPUT APPARATUS AND METHOD OF CONTROLLING THE SAME
First Claim
1. An input apparatus comprising:
- an input detector which detects an input by the blockage of a light beam to scan a scan region;
a vibration detector which detects a vibration equal to or more than a set sensitivity applied to the input detector;
a controller which stops the light beam scanning when the input detector detects no inputs for a given length of time, and restores the light beam scanning when the vibration detector detects a vibration; and
a sensitivity adjustment unit which changes the sensitivity of the vibration detector to be weaker than the set sensitivity when the input detector detects no inputs and the vibration detector continuously detects vibrations after the controller has restored the light beam scanning.

Abstract
According to one embodiment, an input apparatus comprises an input detector, a vibration detector, a controller, and a sensitivity adjustment unit. The input detector detects an input by the blockage of a light beam to scan a scan region. The vibration detector detects a vibration equal to or more than a set sensitivity applied to the input detector. The controller stops the light beam scanning when the input detector detects no inputs for a given length of time. The controller restores the light beam scanning when the vibration detector detects a vibration. The sensitivity adjustment unit changes the sensitivity of the vibration detector to be weaker than the set sensitivity when the input detector detects no inputs and the vibration detector continuously detects vibrations after the controller has restored the light beam scanning.

9. An input apparatus comprising:
-
an input detector which detects an input by the blockage of a light beam to scan a space between a light-emitting element and a light-receiving element that are disposed to face each other across a scan region; a vibration detector which detects a vibration equal to or more than a set sensitivity applied to the input detector; a controller which stops the operations of the light-emitting element and the light-receiving element when the input detector detects no inputs for a given length of time, and restores the operations of the light-emitting element and the light-receiving element when the vibration detector detects a vibration; and a sensitivity adjustment unit which changes the sensitivity of the vibration detector to be weaker than the set sensitivity when the input detector detects no inputs and the vibration detector continuously detects vibrations after the controller has restored the operations of the light-emitting element and the light-receiving element. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of controlling an input apparatus, the input apparatus comprising an input detector which detects an input by the blockage of a light beam to scan a scan region, a vibration detector which detects a vibration equal to or more than a set sensitivity applied to the input detector, and a controller the method comprising:
-
causing the controller to stop the light beam scanning when the input detector detects no inputs for a given length of time; causing the controller to restore the light beam scanning when the vibration detector detects a vibration; and causing a sensitivity adjustment unit to change the sensitivity of the vibration detector to be weaker than the set sensitivity when the input detector detects no inputs and the vibration detector continuously detects vibrations after the controller has restored the light beam scanning. - View Dependent Claims (18, 19, 20)
