Description of the invention (1) ~, [Technical field to which the invention belongs] The present invention relates to an image sensing module, and in particular to an image that shortens the optical path length Sensor module and film scanner using the image sensor module. I. [Such Technology] Figure 1 shows the intention of scanning the reflection draft of the traditional contact image sensor module. As shown in FIG. 1, a conventional contact image sensor module includes a body 111 ′, an image sensor 11 2, a lens array 11 6, a cover glass layer 1 1 7, and a light emitting diode 2 Polar body (LED) 1 30. The image sensing is that 1 1 2 is located at the bottom of the body 1 1 1 and includes a plurality of single-color light-sensitive units 113 and a light-transmitting layer 1 1 4 for packaging the light-sensitive units 113. The lens array 1 1 6 includes a plurality of lenticular lenses. I should note that the lenticular lens and the photosensitive unit 丨 3 are arranged in a direction of u, which is perpendicular to the drawing. The cover glass layer 1 1 7 covers the lens array 1 16 and L E D 1 3 0, and the dust affects the characteristics of the image sensing module 11 0. The light emitted by the LED 130 passes through a light guide rod (not shown), covers the glass layer 117, and shines on the reflection draft. The reflection draft 丨 reflects part of the light rays, and the reflected light rays are respectively on the light unit 11 13 of the cylindrical lens of the lens array 丨 6 so that the image signals corresponding to the reflection draft 丨 can be obtained. In current cis (contact image sensor) scanners, the length of the module is approximately equal to the width of the document to be scanned. For example, the length of the CIS module used by the cis scanner of M = inch is about 21mm, t. Therefore, for the lens array 116, the object distance is approximately equal to the image of the house: get = the magnification is 1, which is the same as the length of the cis module is approximately equal to the width of the document. Moreover, the sensing used by the contact image sensor module =
