1. A fingerprint identifying system comprising:
- a light-transmissive finger press plate having a top face adapted to contact a finger;
a light source emitting a light beam adapted to interact with the finger on the top face of the light-transmissive finger press plate;
a beam-splitter disposed below the finger press plate and splitting the light beam reflected or refracted by the light-transmissive finger press plate into a transmission light beam and a reflection light beam; and
an image-capturing unit receiving the reflection light beam from the beam-splitter, wherein the image-capturing unit is disposed above the beam-splitter, and the beam-splitter transmits the reflection light beam to the image-capturing unit.

Abstract
A fingerprint identifying system includes a light-transmissive finger press plate, a light source, a beam-splitter, and an image-capturing unit. The light-transmissive finger press plate has a top face adapted to contact a finger. The light source emits a light beam adapted to interact with the finger on the top face. The beam-splitter is disposed below the finger press plate and splits the light beam into a transmission light beam and a reflection light beam. The image-capturing unit receives at least one of the transmission light beam and the reflection light beam from the beam-splitter.

11. A fingerprint identifying system comprising:
-
a light-transmissive finger press plate having a top face adapted to contact a finger; a light source emitting a light beam adapted to interact with the finger on the top face; a beam-splitter disposed below the finger press plate and splitting the light beam from the light source into a transmission light beam and a first reflection light beam; an image-capturing unit receiving at least one of the transmission light beam and the first reflection light beam from the beam-splitter; and a reflecting member disposed above the beam-splitter, the image-capturing unit and the light source being disposed below the beam-splitter, the image-capturing unit being disposed on one side of the light source, the reflecting member and the image-capturing unit being substantially aligned in a vertical direction, the beam-splitter sending a second reflection light beam to the reflecting member, and the second reflection light beam received by the image-capturing unit being a tertiary reflection light beam from the reflecting member.

12. A fingerprint identifying system comprising:
-
a light-transmissive finger press plate having a top face adapted to contact a finger; a light source emitting a light beam adapted to interact with the finger on the top face; a beam-splitter disposed below the finger press plate and splitting the light beam from the light source into a transmission light beam and a reflection light beam; and an image-capturing unit receiving the reflection light beam from the beam-splitter; wherein the image-capturing unit and the light source are disposed below the beam-splitter, the transmission light beam is reflected by the light-transmissive finger press plate, the transmission light beam reflected by the light-transmissive finger press plate is further transmitted through the beam splitter before being received by the image- capturing unit. - View Dependent Claims (13)
