<P>PROBLEM TO BE SOLVED: To provide an image sensor module with a light source unlikely to cause uneven brightness. <P>SOLUTION: An image sensor module 101 includes: a light receiving means having a plurality of light receiving parts arranged in a main scanning direction x; first and second light emitting means 410 and 420 which respectively have a plurality of first and second light emitting elements 412 and 422 arranged in the main scanning direction x, and illuminate a reading object located on one side in a thickness direction; and a case 200 to store the first light emitting means 410 and the second light emitting means 420. The plurality of first light emitting elements 412 include a pair of first light emitting elements 412 spaced apart by a first distance dP and adjacent to each other in the main scanning direction x. The plurality of second light emitting elements 422 include the second light emitting elements disposed at a position sandwiched between the pair of first light emitting elements 412 in the main scanning direction X. <P>COPYRIGHT: (C)2013,JPO&INPIT |
