  However, the personal authentication device is generally installed in a house, outdoor warehouse, apartment, etc. where anyone can approach, and the personal biometric data input part of the personal authentication device is open, so it can be mischievous. There was a problem that the input unit was blocked, personal biometric data could not be input, personal authentication could not be performed, and the building could not be entered.

  An object of the present invention is to provide a personal authentication device that protects a personal biometric data input unit and can perform a personal authentication operation with certainty.

  The present invention provides at least an openable / closable lid that covers the personal biometric information input unit, a fixing unit that locks or releases the lid inside the device, and a control unit that controls the fixing unit, and a personal registration number input unit. When the entered personal registration number matches the pre-registered personal registration number, the personal biometric information input unit is opened by releasing the lock of the fixing unit by the control unit, thereby enabling the input of personal biometric data. Achieved.

  Specifically, the present invention relates to a personal authentication apparatus having a personal registration information input unit and a personal biometric information processing unit, and a personal biometric information input unit, and an opening lid that covers at least the personal biometric information input unit. A fixing unit that locks or releases the opening lid, and a control unit that locks or releases the fixing unit by comparing information input from the personal registration information input unit with pre-registered personal registration information It is characterized by having.

  It is preferable that the personal biometric information input unit is a finger personal vein information input unit, the personal biometric information processing unit is a finger personal vein information processing unit, and the personal vein information processing unit is provided on the finger. On the other hand, a light source unit that irradiates transmitted light, an interference filter unit having optical transparency with respect to an arbitrary wavelength, an imaging unit that images transmitted light that has passed through the interference filter unit, and the output from the imaging unit An image processing unit for finger vein image data, a collation unit that collates the processed image data with pre-registered image data, and an output unit that outputs a processing result of the collation processing unit Is preferred.

  The personal vein information of the finger is for 10 fingers, and it is preferable to authenticate any finger with at least one finger, but authentication with multiple fingers complicates the device itself, but more accurate authentication Is more preferable. The location of the finger authentication is preferably performed between the second indirect and the third indirect. Further, authentication with the middle finger is preferable because finger rolling can be reduced in finger setting.

  The opening lid portion has a lid that is rotatably installed and an electromagnet that is locked or released by a signal from the control unit, or the opening lid portion is a lid that is installed to be movable up and down, A drive mechanism unit that drives the lid up and down, a lid opening / closing instruction button, and a monitoring camera that is driven by a signal from the lid opening / closing instruction button; from the control unit based on an image input by the monitoring camera; It is preferable that the drive mechanism unit is driven by the above signal.

  The personal registration information input unit has a numeric keyboard and a liquid crystal display unit, and the personal vein information input unit has a finger insertion unit, and the base of the finger at the entrance after the insertion of the finger It is preferable to have at least one of a finger pressing portion that restricts the vertical position of the finger and a finger abutting portion that restricts the tip position after insertion of the finger. The finger pressing portion has a concave shape in which the entrance tip of the finger insertion portion follows the shape of the finger so that the finger does not move in the lateral direction, and the finger is between the second indirect and the third indirect. It has a convex shape such that the base of the finger is slightly lifted from the tip of the finger so as not to directly contact the main body of the insertion portion. On the other hand, the front end of the finger insertion portion may have a concave shape along the shape of the finger so that the finger does not move laterally. For the purpose of restricting the insertion length and improving the reproducibility of the finger vein image, the finger abutting portion can prevent the displacement in the finger long axis direction and can always set the insertion length to the correct position.

  ADVANTAGE OF THE INVENTION According to this invention, when authenticating an individual or a group of several persons using personal biometric data, the personal biometric data input part can be protected and the personal authentication apparatus which can perform personal authentication operation reliably can be provided.

Image data processing and personal registration NO. Input process and personal registration NO. And a data processing unit 32 for performing a control process for releasing the lock of the electric excitation magnet 10 when the verification matches. The light source unit 22 has nine light emitting diodes formed in a row on a flat insulating substrate.

  The data processing unit 32 includes an image processing unit 25 that creates collation data in order to collate finger vein image data output from the imaging unit 24 with data stored in the storage unit 28 in advance. A storage unit 28 that stores data, a collation unit 29 that collates finger vein image data created by the image processing unit 25 with finger vein image data stored in advance in the storage unit 28, and a control unit 27 that controls the personal authentication device. The communication processing unit 26 transmits the collation result to the other device 31.

  The finger insertion unit 2 of the authentication target finger 7 of the personal authentication device restricts the insertion length of the authentication target finger 7 when the authentication target finger 7 is inserted, and restricts the position of the authentication target finger 7 when the image is captured. For the purpose of improving the reproducibility of the finger vein image, the finger abutting unit 4 that abuts the tip of the finger at the innermost part of the insertion part of the authentication target finger 7 is provided in order to prevent displacement in the finger long axis direction. The insertion length of the authentication target finger 7 can always be set to the correct position by the finger abutting unit 4. Further, in order to prevent the shift in the short axis direction of the finger and the rotation about the long axis of the finger, the triangular mark 1 indicating the center position 20 of the insertion finger at the entrance of the finger insertion part of the case 9 and the image capturing unit of the finger In order to prevent positional deviation, a lower finger base pressing portion 3 that presses the finger base portion to the lower portion of the entrance of the finger insertion portion is provided. Further, a movable finger abutting section 4 is provided, and the authentication target finger 7 reaches the finger abutting section 4 to move the finger abutting section 4 in the finger axis direction, and the start switch 5 is turned on.
