Patent ID: 7381941

Claim:
A contact image sensing module with a movement detecting function, comprising: a main circuit substrate being a flex-rigid composite substrate, the main circuit substrate comprising a first rigid circuit substrate, a second rigid circuit substrate, a third rigid circuit substrate, and at least a flex circuit board, wherein the first rigid circuit substrate, the second rigid circuit substrate and the third rigid circuit substrate are electrically connected to the at least a flex circuit board so as to form, respectively, a first composite substrate, a second composite substrate and a third composite substrate, the second composite substrate and the third composite substrate respectively tilted upward by a predetermined angle relating to the first composite substrate; a linear sensor array mounted on the second composite substrate; at least a movement detecting element mounted on the second composite substrate and parallel-arranged at one side of the linear sensor array; a light source mounted on the third composite substrate; and a detecting surface defined at one side of the linear sensor array and the at least a movement detecting element, wherein the detecting surface is used for placement of a sensed object thereon, a light from the light source is transmitted to the detecting surface, and the light is then reflected by the sensed object to the linear sensor array and the at least a movement detecting element.
