Fingerprint input apparatus and personal authentication system
First Claim
1. A fingerprint input apparatus comprising:
- illumination means for irradiating a finger with a light;
a solid-state image pickup element substrate on which a solid-state image pickup element is formed; and
a protective member adhered to a surface of said solid-state image pickup element substrate, at the same side on which the solid-state image pickup element is formed,wherein a fingerprint image of said finger is read while sliding said finger on a surface of said protective member,wherein the solid-state image pickup element substrate and the protective member each have two longitudinal sides extending in a direction perpendicular to a direction of sliding the finger, such that one longitudinal side of the solid-state image pickup element substrate is aligned in the same plane with one longitudinal side of the protective member in a thickness direction of the protective member, while the other longitudinal side of the solid-state image pickup element substrate is aligned in the same plane with the other longitudinal side of the protective member in a thickness direction of the protective member,wherein the illumination means and the solid-state image pickup element substrate are arranged side by side on a wiring substrate along the direction of sliding said finger, andwherein the solid-state image pickup element substrate has a portion of its surface on which the solid-state image pickup element is formed, at least at one end of the solid-state image pickup element substrate in the longitudinal direction, to which the protective member is not adhered, such that the solid-state image pickup element substrate is exposed.

Abstract
The invention provides a fingerprint input apparatus capable of more stably providing an image “of a higher definition than in prior technologies. The fingerprint input apparatus includes an LED chip 10 and a solid image pickup device substrate 1 adapted to irradiate a finger 20 of a fingerprint inputting person with & light from the LED 10 and bearing a solid image pickup device for receiving light scattered in the interior of the finger, and reads the fingerprint of the finger 20 based on a light reception signal of the solid image pickup device. The solid image pickup device is constituted of a one-dimensional or two-dimensional image pickup device formed on a rectangular solid image pickup device substrate. A rectangular protective member 30 is adhered to a side, to be contacted by the finger 20, of the solid image pickup device substrate 1. In the protective member 30, among four sides L1, L2, W1 and W2 constituting a rectangular external shape, two longer sides L1 and L2 and a shorter side W1 have the same shape as the external, shape of the solid image pickup device substrate 1.
