Description

  The present invention relates to a finger information detection apparatus for detecting features of a living body, particularly finger features such as finger veins and fingerprints.

  A conventional automatic teller machine is equipped with a fingerprint detection device that uses a fingerprint as a biometric feature of a finger as finger information as a finger information detection device on the front panel of the automatic teller machine. Register the customer's fingerprint data, generate fingerprint data from the image data read by the fingerprint detection unit, and collate the generated fingerprint data and the fingerprint data read from the IC card with the verification unit provided in the automatic teller machine And verifying the identity.

  The customer's fingerprint data is registered in the fingerprint database of the host computer connected to the automatic teller machine via a communication line in correspondence with the PIN, and the automatic teller machine uses the image data read by the fingerprint detection unit. The generated fingerprint data and the password entered by the customer are sent to the host computer. The host computer verifies the customer's fingerprint data registered based on the password and the received fingerprint data without using a transaction card. The person is verified.

  Furthermore, the customer's fingerprint data is registered in the fingerprint database of the host computer in correspondence with the account number, and the automatic teller machine transmits the customer's account number read from the transaction card to the host computer. The corresponding fingerprint data is read out from the fingerprint database and sent to the automatic teller machine, and the automatic teller machine compares the fingerprint data generated from the image data read by the fingerprint detection unit with the received fingerprint data. Identity verification is performed (see, for example, Patent Document 1).

A conventional fingerprint detection apparatus used in such a case is provided with a slide-type shutter that covers the fingerprint detection unit and protects its detection surface. A spring is attached to the shutter, and when the shutter is pushed up by the tip of the finger, the shutter is released. When the detection surface is exposed by sliding the groove and the shutter is fully open, the fingerprint image up to the first joint of the finger can be detected, and it is configured to automatically close by a spring when the finger is released. Surface contamination and damage are prevented (see, for example, Patent Document 2).
JP-A-10-134229 (mainly third page paragraph 0009-paragraph 0011, fourth page paragraph 0016-paragraph 0018 and fifth page paragraph 0022-paragraph 0023, FIGS. 1 to 3) JP 2002-157586 (3rd page paragraph 0007 and 4th page paragraph 0031-paragraph 0034, FIG. 3)

  However, in the technique of the above-described conventional patent document 2, the shutter is opened by pushing up the shutter at the tip of the finger, and the fingerprint image up to the first joint of the finger is detected by the fingerprint detection unit in a state where the shutter is fully opened. Therefore, when the customer has a long finger or when the customer's nail is extended, the length from the tip of the finger to the first joint changes, and the fingerprint image in a predetermined area cannot be detected. There is a problem that misrecognition may occur at the time of collation of fingerprint data due to the length of the nail or the nail, which causes discomfort to the customer.

This means that in the case of a woman with a long nail whose customer has extended or put on a nail, the length from the tip of the finger (tip of the nail) to the first joint becomes longer, so the above problem becomes remarkable. In addition, in order to worry about breakage of the nail, if the shutter is pushed on the ventral side of the tip of the finger, the finger may be too far from the detection surface, and there is a possibility that accurate fingerprint data cannot be detected.
For this reason, when the shutter is removed and the detection surface is exposed, dust on the detection surface when the fingerprint detection device is not used, contamination of the detection surface due to adhesion of sebum due to tampering, and detection surface due to tampering There is a problem in that, for example, a scratch or the like occurs, and erroneous recognition occurs at the time of collation of fingerprint data, resulting in discomfort to the customer.

The same applies to the case where the finger vein as a biological feature of the finger is used as the finger information.
The present invention has been made to solve the above-described problems, and an object thereof is to provide means for accurately detecting finger information without causing discomfort to the customer.

  In order to solve the above-described problems, the present invention provides a finger information detection unit that detects a biological characteristic of a finger via a detection surface, and a detection surface shutter that covers the detection surface and opens and closes the detection surface in the surface direction. In the finger information detecting apparatus, the detection surface shutter is opened and closed by automatic control.

  As a result, the present invention allows the customer to input finger information of the finger for collating the customer's finger information on the detection surface of the finger information detection unit that is automatically exposed by opening the detection surface shutter. The finger information can be accurately detected regardless of the length of the sensor, and it is possible to prevent the customer from feeling uncomfortable and not to forget to close the detection surface shutter. An effect is obtained that it is possible to prevent surface recognition and damage and prevent erroneous recognition when detecting finger veins.
