Abstract

The invention relates to a light source module of a scanner which comprises a lamp bracket, a first lighting set and a second lighting set, wherein, the lamp bracket comprises a scanning port and an exit port arranged at interval. The first lighting set is arranged on the lamp bracket and positioned at one side of the exit port on the cross direction, and comprises a plurality of first LED lights arranged at intervals along the length direction of the exit port; the second lighting set is arranged on the lamp bracket and positioned at the other side of the exit port on the cross direction, and comprises a plurality of second LED lights which are arranged at interval along the length direction of the exit port and staggered with the first LED lights.

Description

technical field [0001] The invention relates to a scanning device, in particular to a scanner light source module. Background technique [0002] The traditional scanner light source module uses cold cathode fluorescent lamps (CCFL) as the main light source. The main disadvantage of this method is that the warm-up time is too long each time it is turned on, and this disadvantage is more obvious in low temperature environments. . In order to reduce the waiting time before cold machine scanning, in order to provide effective and fast scanning and preview functions, scanners using light-emitting diodes (LEDs) as light sources have been developed for this purpose. [0003] refer to figure 1 , an existing scanner 1 using LED lights as light sources, including a main body 11 , a light-transmitting plate 12 , an LED light set 13 , a mirror set 14 , and an image capture unit 15 . Wherein, the body 11 includes a reflective chamber 111; the light-transmitting plate 12 is installed a...
