Summary:PROBLEM TO BE SOLVED: To provide an image sensor module suitable for eliminating or suppressing inconveniences caused by distortion of a case, and the like.SOLUTION: There is provided an image sensor module which has a light-emitting unit that reads out linear light extending in a main scanning direction and emits toward an object to be read, a light-receiving sensor extending in the main scanning direction, a lens unit condensing the light emitted from the object to be read in the light-receiving sensor, a substrate that is separated from the lens unit in a thickness direction z perpendicular to the main scanning direction and has the light-receiving sensor mounted thereon, and a case 200 having a light-emitting unit storage section 230 storing the light-emitting unit, a lens unit storage section 240 storing the lens unit and a substrate storage section 250 storing the substrate and is formed from a resin material, where the lens unit storage section 240 has a lens unit storage section bottom surface 241 that faces one direction of the thickness direction z and extends to the main scanning direction, and a projection 210 projecting to the thickness direction z is formed on the lens unit storage section bottom surface 241.SELECTED DRAWING: Figure 9 【課題】ケースの歪み等に起因する不都合を解消ないし抑制するのに適するイメージセンサモジュールを提供すること。【解決手段】主走査方向に延びる線状光を読み取り対象物に向けて出射する発光ユニットと、主走査方向に沿って延びる受光センサと、読み取り対象物からの光を受光センサに集光するレンズユニットと、レンズユニットと主走査方向に対して直角である厚さ方向zにおいて離間し、受光センサが搭載された基板と、発光ユニットを収容する発光ユニット収容部230、レンズユニットを収容するレンズユニット収容部240、基板を収容する基板収容部250、を有し、樹脂材料により形成さえるケース200と、を備え、レンズユニット収容部240は、厚さ方向z一方を向き、主走査方向に延びるレンズユニット収容部底面241を有し、レンズユニット収容部底面241には、厚さ方向zに突き出る突起210が形成されている。【選択図】図9
