The keyboard 921 is attached to the side to which the display unit 930 is connected, and the vein authentication module 40 is located near the right end portion on the front side of the main body unit 920 opposite to the side to which the display unit 930 is connected. It is installed.

  The vein authentication module 40 scans a hand and reads information about the hand. Specifically, as shown in FIG. 2, the planar shape is substantially square, and the user holds the palm on the reading surface 41 side to read the vein of the palm and input biometric information. It is an input device that can. The reading surface 41 of the vein authentication module 40 has a vein sensor capable of acquiring a biometric image of a vein in the palm of the user.

  The vein of the palm read by the vein sensor in the vein authentication module 40 has a large amount of information as compared with the veins of other parts, which is advantageous for identification, and since the blood vessel is thick, it is not easily affected by cold and warm, and accurate authentication is stable. You can do it. The information on the veins of the palm is difficult to forge because it is the information inside the body, and it is less susceptible to the effects of rough hands and dryness / wetness of the hands, which is advantageous as biometric information. Further, since biometric information can be acquired in a non-contact manner, it can be performed in a hygienic and natural manner, the user's feeling of resistance is small, and authentication can be performed at high speed.
