Abstract

The structure of the pointing device that does not limit the operator because of the individual's physique is as follows: the device (112) that the pointing device is installed includes: a fingerprint sensor (20) that obtains image information; a cover (1) that protects the sensor surface; A sensor pressing part (11) arranged on the side surface and in contact with the sensor surface. The shape of the sensor pressing part (11) obtained by the sensor (20) changes with the position where the finger presses the cover (1), and input is performed accordingly.

Description

technical field

[0001] The present invention relates to a sensor protection cover and a pointing device, and more particularly to a sensor protection cover for use in providing instructions to a computer using a fingerprint sensor, and a small pointing device capable of performing continuous input. Background technique

[0002] Japanese Patent Application Laid-Open No. 2002-062983 discloses that the movement of a finger on a fingerprint authentication device is detected as an input to a computer, and a single device is used to realize a touch panel device and a fingerprint authentication device.

[0003] In the technology of the above-mentioned Japanese Patent Laid-Open No. 2002-062983, the operations performed by the computer are performed according to the movement and deformation of the fingerprint pattern obtained by the fingerprint sensor.

[0004] However, the shading and sharpness of an image obtained by a capacitive fingerprint sensor are likely to be largely affected...
