Description

  The present invention relates to a biometric information registration apparatus that registers biometric information in a transaction card used in a financial institution or the like.

In financial institutions and the like, when taking counter measures against transaction cards such as cash cards and credit cards, the transaction card is an IC card, and biometric information is registered in this card to authenticate customers.
The conventional biometric information registration apparatus used in this case is provided with image receiving means for irradiating light emitted from the light source from the ventral side of the finger of the hand and photographing reflected infrared light, and the finger vein imaged by this image receiving means A plurality of feature points of the image are registered as finger vein data.

Further, a palm vein image of the palm is photographed by an image receiving means having a similar configuration, and a plurality of feature points of the palm vein image are registered as palm vein data (see, for example, Patent Document 1).
JP-A-7-21373 (3rd page, paragraphs 0015-0023, FIGS. 1 and 4)

However, in the above-described conventional technology, when registering finger veins and palm veins, it is necessary to have separate image receiving means for photographing each of them, so both finger vein data and palm vein data are transaction cards. In the case of registering to the Internet, it is necessary to prepare two types of registration devices, which increases the burden on financial institutions.
In addition, the customer needs to register in two steps by using two types of registration devices, and it takes time to register biometric information, and there is a problem that efficiency in registering biometric information is reduced.

Furthermore, since there are individual differences in the size of the customer's hand, it is difficult to accurately detect each finger vein and palm vein, which are two types of biological information relating to the hand, at the same time. There is a problem.
The present invention has been made to solve the above problems, and provides a means for efficiently registering two types of biological information and accurately detecting data of finger veins and palm veins to be registered. Objective.

In order to solve the above problems, the present invention comprises a finger vein detection sensor for detecting a finger vein pattern of a hand , and a palm vein detection sensor for detecting a palm vein pattern, the finger vein detection sensor, In the biometric information registration device in which the distance from the palm vein detection sensor is variable, the wrist guide is provided with a fixed wrist guide for positioning the wrist, and a finger vein detection sensor moving mechanism for moving the finger vein detection sensor. The palm vein detection sensor is installed with reference to the above, and the finger vein detection sensor is moved according to the length of the finger to be detected by the finger vein detection sensor moving mechanism .

  Thus, according to the present invention, if the customer sets the hand to register once, the finger vein and the palm vein can be simultaneously registered in the transaction card, and two types of biological information can be efficiently registered. The finger vein detection sensor or palm vein detection sensor can be moved so that the finger and palm can be positioned at the appropriate positions of the finger vein detection sensor and palm vein detection sensor with the finger to be registered extended. It is possible to obtain the effect of accurately detecting data of finger veins and palm veins by absorbing individual differences in size.
