Abstract

A Reflective and Penetrative Scanning Apparatus has a body, a first ambulatory reflection module, a second ambulatory reflection module, a lens assembly, an image shooting unit and an adjustment means. The body incorporates a Reflective Script Platform and a Penetrative Script Platform. The First Ambulatory Reflection Module is equipped with two Light Sources and two lenses with which to produce two different Light Paths such that once the switching goes to the First Light Path, a light that is emitted from the Light Source will travel by way of the Reflective Script Platform to the Lens Assembly and the Image Shooting Unit, to execute Reflective Scanning operation and when the switching goes to the second Light Path, another light that is emitted from the Light Source will travel by way of the Penetrative Script Platform to the Lens Assembly and the Image Shooting Unit, to execute Penetrative Scanning Operation.

Dependent claims

A composite reflective/penetrative scanning apparatus, comprising:

a body which includes a reflective script platform serving to hold a reflective script in position, and an access port on one side thereof;
a penetrative script platform inside the body and coupled to said access port to accept and support a penetrative script fed via said access port;
a first ambulatory reflection module which includes:
a first light source that emits a first light beam to the reflective script platform;
a second light source that emits a second light beam to the penetrative script platform;
a first mirror arranged symmetrical with the reflective script platform, and which receives the light beam that is reflected from the reflective script platform;
and
a second mirror arranged symmetrical with the penetrative script platform;
a second ambulatory reflection module which includes symmetrically arranged third and fourth mirrors, wherein the first mirror reflects the light beam that is reflected from the reflective script platform to the third mirror;
a drive assembly that drives the first and second ambulatory reflection modules into linear movement with respect to the body at a 2:1 speed ratio;
a lens assembly that receives a light reflected from the fourth mirror and converges same into an image;
an image shooting unit that receives the converged image from the lens assembly and converts same into electronic signals;
and
adjustment means, associated with the lens assembly and the image shooting unit, to adjust the vertical positioning of both the lens assembly and the image shooting unit between a first position and a second position;
wherein when set in the first position, both the lens assembly and the image shooting unit will accept a light beam that is emitted from the first light source, and which comes by way of the reflective script platform, the first mirror, the third mirror and fourth mirror in that sequential order, in a reflective mode of scanning;
and
wherein when the lens assembly and the image shooting unit are set in the second position, the lens assembly and the image shooting unit will accept a light beam as emitted from the second light source, coming by way of the penetrative script platform, the second mirror, the third mirror and the fourth mirror, in that sequential order, in a penetrative mode of scanning.

a first ambulatory reflection module and a second ambulatory reflection module;
a drive assembly that drives the first and second ambulatory reflection modules into linear movement at a 2:1 speed ratio relative to the body;
a lens set that receives a light beam reflected from the second ambulatory reflection module and converges same into an image;
an image shooting unit that receives the converged image from said lens set and converts same into electronic signals;
adjustment means that is coupled to said lens set and image shooting unit to switch, through adjustment processing, said lens set and image shooting unit between a first light path and a second light path;
wherein said first ambulatory reflection module further incorporates:
a first light source that provides a light beam that is emitted to the reflective script platform;
a second light source that provides a light beam that is emitted to the penetrative script platform;
a first mirror that receives a light that is reflected from the reflection script platform;
and
a second mirror that receives a light that is reflected from the penetrative script platform;
wherein once the lens set and the image shooting unit are both aligned with the first light path, the lens set and the image shooting unit will both receive the light emitted from the first light source via the reflective script platform, the first mirror and the second ambulatory reflection module, in a reflective mode of scanning;
and
when the lens set and the image shooting unit are both aligned with the second light path, the lens set and the image shooting unit will both receive the light emitted from the second light source via the penetrative script platform, the second mirror, and the second ambulatory reflection module, in a penetrative mode of scanning.
