センサヘツド。[Scope of Claim for Utility Model Registration] (1) In a printing defect detection sensor head that detects defects in printed matter by performing color photometry, multiple sets of light emitting optical fibers formed in layers using a plurality of optical fibers are provided. a plurality of light-receiving optical fiber layers formed in a layered form using a plurality of optical fibers and arranged alternately adjacent to each of the light-emitting optical fiber layers; and a color detection method for printing defects. Therefore, a plurality of color sensor elements corresponding to red, green, and blue, a plurality of sets of light projecting means for projecting light onto the plurality of sets of light projecting optical fiber layers, and a control device provided with an amplifier at the front stage are provided. strip-shaped spacers are interposed between the plurality of sets of light-emitting optical fiber layers and the plurality of light-receiving optical fiber layers, and the plurality of sets of light-receiving optical fiber layers are colored red, green, connect the plurality of color sensor elements in the order of blue, and adjust the light of each of the plurality of sets of light emitting means so that the output of each of the plurality of color sensor elements is within a saturation level. A sensor head for detecting printing defects, characterized in that the sensor head is configured to operate the control device. (2) Two light projecting means are provided, one of which projects light onto the light projecting optical fiber layer disposed at both ends of the light receiving optical fiber layer corresponding to red color, and the other light projecting light to blue light. Light is emitted to the light emitting optical fiber layer disposed at both ends of the corresponding light receiving optical fiber layer, and the light receiving optical fiber layer corresponding to the red color is provided at both ends of the light receiving optical fiber layer corresponding to the green color. Light is emitted from one of the light emitting optical fiber layers disposed at both ends of the layer and one of the light emitting optical fiber layers disposed at both ends of the light receiving optical fiber layer corresponding to the blue color. A sensor head for detecting printing defects according to claim 1 of the registered utility model. (2) If the output levels of the plurality of color sensor elements are extremely different due to dimming of the light projecting means, adjustment can be made by changing the amplification degree of the plurality of amplifiers provided in the control device. A sensor head for detecting printing defects according to claim 1 of the registered utility model.
