PROBLEM TO BE SOLVED: To provide an optical scanning endoscope system that is downsized by storing an optical coupler in a housing of a processor without sacrificing assemblability, and to provide the processor.SOLUTION: A processor 20 comprises: a housing 201 that comprises an optical connector 34 for optically connecting the processor 20 and an optical scanning endoscope 10 a light source 235 that emits illumination light an optical receiver 236 that receives observation light an optical coupler that is optically connected to a first optical fiber 222c, guides the illumination light from the light source 235 to the first optical fiber 222c and guides the observation light guided by the first optical fiber 222c to the optical receiver 236 a control circuit that controls an optical scanner and generates an endoscope image on the basis of the observation light received by the optical receiver 236 and a power source 234 that supplies power. The inside of the housing 201 is divided into at least an upper stage and a lower stage. The lower stage stores the power source 234, the light source 235, the optical receiver 236 and the optical coupler 222, and the upper stage stores the control circuit.COPYRIGHT: (C)2014,JPO&INPIT【課題】組み立て性を損なうことなく光カプラをプロセッサの筐体内に収容することにより、コンパクトな光走査型内視鏡システム及びプロセッサを提供する。【解決手段】プロセッサ20は、プロセッサ20と光走査型内視鏡10とを光学的に接続する光コネクタ34を有する筐体201と、照明光を発する光源235と、観察光を受光する受光器236と、第1の光ファイバ222cと光学的に接続され照明光を光源235から第1の光ファイバ222cに導光すると共に第1の光ファイバ222cによって導光される観察光を受光器236に導光する光カプラ222と、光走査装置を制御し受光器236で受光された観察光に基づいて内視鏡画像を生成する制御回路と、電力を供給する電源234と、を有し、筐体201は、内部が少なくとも上下2段に分かれており、下段に電源234、光源235、受光器236及び光カプラ222を収容し、上段に制御回路を収容する。【選択図】図1
