Title:
IMAGE SENSOR AND BANKNOTE PROCESSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/141801
Kind Code:
A1
Abstract:
An image sensor (311, 313) and banknote processing apparatus. The image sensor (311, 313) comprises a first photosensitive assembly (4) and a first light source assembly (2) used to irradiate light to a note, and further comprises a first lens array (3) configured to aggregate the light reflected by the note and direct the reflected light to the first photosensitive assembly (4). A light-entry surface of the first lens array (3) is located in a transmission path of reflected light emitted from the first light source assembly (2) irradiated on the note and reflected therefrom as a specular reflection. According to different image grayscale values generated by the image sensor (311, 313), the banknote processing apparatus determines whether the banknote surface is bonded with adhesive tape. The present invention has a small number of parts, a compact structure, and a small occupied space, facilitating efficient assembly and device miniaturization.
