Abstract

To provide a hand-held device with built-in fingerprint sensor provided on a control panel, which does not ruins the operability of the movement of a cursor or a pointer of the display screen.

A hand-held device with built-in fingerprint sensor comprises a fingerprint sensor for the fingerprint attestation provided on a control panel. A cursor or a pointer displayed on a display unit is moved according to a time change in the position where the pressure is provided or the movement of the finger on the sensor side of the fingerprint sensor. Further, the timing when said time change is detected is decided according to a time change in the position of the finger on said sensor side or the applied pressure.

Claims

1. A hand-held device with a built-in fingerprint sensor comprising:

a display unit which displays an image,

a control panel

a fingerprint sensor for fingerprint attestation provided on said control panel,

a unit that moves a cursor or a pointer displayed on said display unit according to movement of a finger on said sensor side or a time change in the position of the applied pressure obtained by detecting the movement of the finger on said sensor side or the time change in the position of the applied pressure,

wherein an area of said fingerprint sensor is divided into a grid of 9 meshes in total where a number of meshes of one side is 3,

said unit that moves a cursor detects the movement of the finger or the movement of the applied pressure in any one of the meshes, and moves the cursor displayed on said display unit, and

said fingerprint sensor carries out the fingerprint attestation during the movement of the cursor displayed on said display unit.

2. The hand-held device with built-in fingerprint sensor as set forth in claim 1, wherein timing when said change is detected is decided according to a time change in the position of the finger on said sensor side or the applied pressure.

7. The hand-held device with built-in fingerprint sensor as set forth in claim 1, further comprising:

a fingerprint sensor for attestation provided on a control panel, and

a display unit which displays an image,

wherein step is provided between said control panel and said fingerprint sensor.

8. The hand-held device with built-in fingerprint sensor as set forth in claim 7, wherein said fingerprint sensor is at the position lower than said control panel in said step.

9. The hand-held device with built-in fingerprint sensor as set forth in claim 7, wherein said step has the outline with height from them to the boundary part of said control panel and said fingerprint sensor.

10. A hand-held device with built-in fingerprint sensor according to claim 7, comprising a control panel provided with two or more buttons, and a display unit which displays an image, further comprising;

a fingerprint sensor part provided on the positions where it is easy for the belly side of finger to touch when holding said control panel with either one of right and left hands.

3. A hand-held device with a built-in fingerprint sensor comprising:

a pressure sensor part for fingerprint attestation and for detection of movement of an arbitrary finger, provided on a control panel, and

a display unit which displays a message indicative of the completion of fingerprint registration after said finger is pressed against said pressure sensor until the information necessary for registering fingerprint can be read,

wherein said pressure sensor part is divided into a grid of 9 meshes where a number of meshes of one side is 3, and

wherein said pressure sensor part is detects movement of said finger in any of one of the meshes, and moves the cursor displayed on said display unit, and

wherein a cursor or a pointer displayed on a display unit moved according to a time change in the position where said finger is pressed on the sensor side of the pressure sensor.

4. The hand-help device with built-in fingerprint sensor as set forth in claim 3, wherein the message indicative of the completion of said fingerprint registration at least contains an address (ID) where the fingerprint is registered.

5. The hand-held device with built-in fingerprint sensor as set forth in claim 3, wherein the message indicative of the completion of said fingerprint registration at least contains the image of the fingerprint concerned.

6. The hand-held device with built-in fingerprint sensor as set forth in claim 3, wherein two or more fingerprints are registered in said fingerprint registration.

11. A hand-held device with a built-in fingerprint sensor comprising:

a display unit which displays an image,

a control panel

a fingerprint sensor for fingerprint attestation provided on said control panel,

a means which moves a cursor or a pointer displayed on said display unit according to movement of a finger on said sensor side or a time change in the position of the applied pressure obtained by detecting the movement of the finger on said sensor side or the time change in the position of the applied pressure,

wherein an area of said fingerprint sensor is divided into a grid of 9 meshes in total where a number of meshes of one side is 3,

said means which moves a cursor detects the movement of the finger or the movement of the applied pressure in any one of the meshes, and moves the cursor displayed on said display unit, and

said fingerprint sensor carries out the fingerprint attestation during the movement of the cursor displayed on said display unit.
