Biometric information authenticating device, and biometric information authenticating system
A biometric information authenticating device includes a biometric information sensor to detect contact of an operating finger with a reading surface and to read biometric information of the operating finger, an illumination unit including at least one light source, and a control unit to indicate completion of reading of the biometric information by an illumination pattern including a combination of turning on and off of the at least one light source.
1. A biometric information authenticating device, comprising:
a vehicle start switch device comprising a biometric information sensor to detect contact of an operating finger of an operator with a fingertip reading surface and to read biometric information of the operating finger;
an illumination unit comprising at least one light source; and
a control unit to indicate completion and successful reading of the biometric information by an illumination pattern including a combination of turning on and off of the at least one light source to allow the vehicle operator to remove the operating finger from contact with the reading surface before start-up of the vehicle from the switch device.
2. The biometric information authenticating device according to claim 1 , wherein the biometric information sensor reads one of or both of a fingerprint pattern and a vein pattern as the biometric information.
3. The biometric information authenticating device according to claim 1 , wherein, when contact of the operating finger with the reading surface is detected, the control unit controls the illumination unit to produce a different illumination pattern from the illumination pattern produced at the time of completion of reading of the biometric information.
4. The biometric information authenticating device according to claim 3 , wherein the control unit makes a difference between the illumination pattern produced at the time of detection of the operating finger with the reading surface and the illumination pattern produced at the time of completion of reading of the biometric information by switching between blinking and solid light in the same color.
5. The biometric information authenticating device according to claim 1 , wherein the control unit controls the illumination unit to change the illumination pattern when reading of the biometric information is successful and when failed.
6. The biometric information authenticating device according to claim 1 , wherein, upon successful authentication of the biometric information that is read during contact of the operating finger, the control unit outputs a signal to permit a drive system of a vehicle to start.
7. The biometric information authenticating device according to claim 1 , wherein
the reading surface of the biometric information sensor is arranged so as to be able to read the biometric information of the operating finger in contact with an operation surface of an operating portion of the vehicle start switch device, and
the illumination unit outputs a circle of light that surrounds the operation surface.
8. The biometric information authenticating device according to claim 7 , wherein the illumination unit comprises a light guide that is arranged between the operation surface and a main body positioned around the operating portion and surrounds the operation surface, and light output from the at least one light source is guided by the light guide.
9. The biometric information authenticating device according to claim 7 , wherein the illumination unit is configured that light output from the at least one light source is output from a gap formed between the operation surface and the main body positioned around the operating portion.
10. A biometric information authenticating system, comprising:
a start switch device comprising a biometric information sensor to detect contact of an operating finger with a reading surface and to read biometric information of the operating finger,
an illumination unit comprising at least one light source, and a control unit to control the illumination unit by an illumination pattern including a combination of turning on and off of the at least one light source; and
a vehicle control unit electromagnetically connected to the start switch device and each unit of a vehicle,
wherein the vehicle control unit determines the state of the vehicle and outputs vehicle information to the control unit based on a detection result of contact of the operating finger with the reading surface, completion and successful reading of the biometric information, operation status of the vehicle, and start status of a drive system, and the control unit controls the illumination unit to produce the illumination pattern corresponding to the vehicle information, and
wherein the reading surface of the biometric information sensor is arranged so as to be able to read the biometric information of the operating finger in contact with an operation surface of an operating portion, and
wherein the illumination unit outputs a circle of light that surrounds the operation surface.
