Abstract

PURPOSE: To prevent a face, with which a finger to input a fingerprint pattern gets contact, from being made dirty or damaged by composing a covering means to be slidable in the inserting direction of the finger and to cover the contact face when the finger does not get contact with the contact face.
CONSTITUTION: A slidable cover 23 is arranged on one face 21a of a prism 21 and a flange part 23b covers the face 21a. Therefore, the face 21a is not revealed and hardly made dirty or damaged. When the flange part 23a is pushed by the tip of a finger 22 to input the fingerprint pattern in the case of reading the fingerprint pattern, a cleaner 26 provided on the lower face of the flange part 23b slides in the inserting direction of the finger 22 on the face 21a and cleans the face 21a together with the slidable cover 23. Thus, the contact face is prevented from being made dirty or damaged.
