Problems solved by technology

[0007] In addition, in the existing devices using the fingerprint sensor as a pointing device, the finger must directly touch the fingerprint sensor, and the surface of the sensor must always be exposed.
Therefore, the sensor may be damaged when mounted on a laptop computer or mobile phone
[0008] Moreover, since the operator cannot wear gloves when operating, there will also be problems when using in cold regions
[0009] In addition, since the surface of the sensor is exposed, the degree of freedom in the design of the entire device is limited.

Embodiment approach

[0082] Figure 13 Shown is a structural diagram of a device equipped with a pointing device according to another embodiment of the present invention.

[0083] The device equipped with this pointing device consists of a sensor 20 for obtaining image information, a cover 1 for protecting the surface of the sensor, a sensor pressing part 11 arranged on the surface of the sensor side of the cover and in contact with the sensor surface, inserted into the cover 1 and pressed. The pressing direction adjustment auxiliary material 111 between the parts 11 is composed.

[0084] This structure is different from the aforementioned structure ( Figure 6 etc.) in that there is a pressing direction adjustment auxiliary material 111 inserted between the cover and the pressing portion.

[0085] In the aforementioned structure, depending on the material of the cover and the pressing part (for example, when the material is relatively soft), it may happen that each pressing part 11 presses the ...

[0097] Implementation Effects of Other Embodiments

[0098] In this embodiment, an auxiliary material for adjusting the pressing direction is inserted between the cover and the sensor. According to this configuration, the pressure generated by pressing is applied to the cover with directionality, and the pressure transmitted to the sensor through the sensor pressing portion also has directionality. Accordingly, even on the sensor output image, the area pressed by the pressing portion has an area reflecting the position and intensity of the pressing, so that the movement of the operator's finger can be more accurately detected.

[0099] In addition, in a modified example, the cover is made of a pressing direction adjustment auxiliary material, and the pressing part is made of a material that does not damage the surface of the sensor and is softer than the pressing direction adjustment auxiliary material. According to this configuration, by applying the pressing force to the co...

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...
