PURPOSE:To prevent a third party from decoding a password number by providing a selecting means, which selects a single type of a figure out of the figures of a display means, a confirming means, and a panel, where the display means is provided at a position more hollow than a front surface. CONSTITUTION:A password number input means consists of a display means 21 to display the figures, a selecting means 22 to select a single type of the figure out of the figures on the display means 21, a confirming means 23 to confirm the selected figures, and a panel 24 where the display means 21 is provided at the position more hollow than the front surface. Consequently when a card possessing person inputs the password number, since the display means 21 is provided at the position more hollow than the front surface, it cannot be seen by the third party, and the motion of the finger of the card possessing person is only the operation of the selecting key 22 and the confirming key 23. Thus the third party cannot decode the password number by the input operation of the password number. |
