Embodiment Construction

[0026] see figure 1 , figure 1 It is a schematic diagram of a detection device 50 in a preferred embodiment of the present invention. The detection device 50 is used to detect the position of an edge 521 of a light-transmitting medium 52 as a basis for positioning; for example, the light-transmitting medium 52 can be a transparent card, and when the detection device 50 detects the transparent card, subsequent card printing or card data reading actions can be performed, such as automatic teller machines can recognize the passing of the transparent card, and then start the related functions of reading the card, etc. The detection device 50 includes an actuating unit 54, which is used to drive the transparent medium 52 to move in the X direction; The direction in which the actuating unit 54 drives the light-transmitting medium 52 (X direction) can be substantially perpendicular to the light emitting direction (Y direction) of the light source 56 , and the light source 56 can be ...

Abstract

A detecting device includes an actuating unit for driving a transparent material, a light source for emitting light to the transparent material driven by the actuating unit, a light sensor for sensing the light emitted from the light source as an edge of the transparent material is moved to different positions relative to the light source so as to generate a corresponding optical intensity signal, a transforming circuit coupled to the light sensor for transforming the optical intensity signal into a transforming signal, and a processing unit coupled to the transforming circuit for determining whether the edge of the transparent material is moved to a position between the light source and the light sensor according to the transforming signal transmitted from the transforming circuit.

Description

technical field [0001] The invention relates to a detection device and a detection method for detecting the edge of a light-transmitting medium, in particular to a detection device and a detection method for detecting the edge of a light-transmitting medium by using the change of light sensing intensity. Background technique [0002] Due to the light-transmitting properties of the light-transmitting medium, the optical sensor cannot detect the passage of the light-transmitting medium. Light-transmitting materials, pre-printed light-shielding graphics, or printing special transparent inks that can shield infrared rays on the light-transmitting medium, so that the light sensor inside the machine can detect the relative position of the light-transmitting medium. However, the above-mentioned methods all require an additional manufacturing process on the transparent medium, thus increasing the manufacturing cost and difficulty, and reducing the application popularity of products ...
