置。 In an inspection device for inspecting a light passing state and a light shielding state of an optical coupling device in which a light emitting element and a light receiving element are arranged opposite to each other across a path through which a detected object is passed, and the presence or absence of a detected object is detected without contact. A light-shielding plate switching means for freely inserting and removing a light-shielding plate in the passage of the object, and a reduction in the light emission output of the light-emitting element assumed in the inspection, in which the transmittance at the wavelength of light emitted by the light-emitting element in the passage of the object to be detected is reduced. 1. An inspection device for an optical coupling device, characterized in that an optical attenuation filter switching means is provided for detachably switching an optical attenuation filter having an equal ratio to the optical attenuation filter.
