Fingerprint input apparatus and personal authentication system using the same
First Claim
1. A fingerprint input apparatus comprising:
- solid state image pickup devices;
illuminating means for emitting light into a finger;
a solid state image pickup device substrate on which said solid state image pickup devices are arranged; and
a wiring substrate on which said solid state image pickup device substrate and said illuminating means are arranged, in which the light emitter from the illuminating means and scattered from an inside of the finger is received by said solid state image pickup devices, thereby reading a fingerprint image of said finger, wherein said fingerprint input apparatus further comprises a member which is arranged on said wiring substrate at least in a position between said illuminating means and said solid state image pickup device substrate, said member has the same or almost the same height as that of a surface of said solid state image pickup device substrate with which said finger is come into contact and spatially partitions said illuminating means and said solid state image pickup devices, and positions of said finger and said solid state image pickup device are relatively moved, thereby reading the fingerprint image.

Abstract
A fingerprint input apparatus which is smaller than the conventional one and in which a stable and fine image can be obtained is provided at a reasonable price. The fingerprint input apparatus has: solid state image pickup devices on which a finger of a fingerprint input target person is put; LED chips for emitting light into the finger; a solid state image pickup device substrate on which the solid state image pickup devices are arranged; and a wiring substrate on which the solid state image pickup device substrate and the LED chips are arranged, wherein while relatively moving positions of a fingertip of the finger and the solid state image pickup devices, the light emitted from the LED chip and scattered from the inside of the fingertip is received by the solid state image pickup devices, thereby reading a fingerprint image of the finger. A frame-shaped member is arranged between the LED chip and the solid state image pickup device substrate on the wiring substrate. The frame-shaped member has the same or almost the same height as that of a surface of the solid state image pickup device substrate with which the fingertip is come into contact and spatially partitions the LED chip and the solid state image pickup devices.
