Abstract

An object of the present invention is 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 built-in fingerprint sensor comprising:

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

wherein 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.

2. The hand-held device with built-in fingerprint sensor as set forth in claim 1, wherein 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.

3. The hand-held device with built-in fingerprint sensor as set forth in claim 1, wherein said fingerprint attestation is executed while moving the cursor or the pointer displayed in said display unit.

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

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

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

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

6. The hand-held device with built-in fingerprint sensor as set forth in claim 4, wherein the message indicative of the completion of said fingerprint registration at least contains the image of the fingerprint concerned.

7. The hand-held device with built-in fingerprint sensor as set forth in claim 4, wherein two or more fingerprints are registered in said fingerprint registration.

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

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

a display unit which displays an address (IP) of the fingerprint registered as an attestation fingerprint for function unlocking.

9. The hand-held device with a built-in fingerprint sensor as set forth in claim 8, wherein when the function is unlocked, the fingerprint attestation is executed again if the fingerprint confirmed with said fingerprint sensor to unlock said function does not match with the fingerprint registered as the attestation fingerprint for function unlocking.

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

a fingerprint sensor for fingerprint attestation provided on a control panel, in which two or more fingerprints are memorized by said fingerprint sensor, and

an information registration means which the associated information on each fingerprint is registered,

wherein the use of the information registered in the information registration means is permitted only when the fingerprint attestation matches with the fingerprint which is associated with information registered in the information registration means.

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

a fingerprint sensor for fingerprint 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.

12. The hand-held device with built-in fingerprint sensor as set forth in claim 11, wherein said fingerprint sensor is at the position lower than said control panel in said step.

13. The hand-held device with built-in fingerprint sensor as set forth in claim 11, wherein said step has the outline with height from them to the boundary part of said control panel and said fingerprint sensor.

14. A hand-held device with built-in fingerprint sensor 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 position where it is easy for the berry side of finger to touch when holding said control panel with either one of right and left hands.
