Focusing type optical transmission body array

Abstract

Abstract PURPOSE: To readily make the focusing type optical transmission body array in which focusing type optical transmission bodies are arrayed with high accuracy by sandwiching the focusing type optical transmission bodies by the frames provided with parallel grooves of the specified pitch. CONSTITUTION: Grooves 8a... are provided is parallel at the pitch equal to or slightly larger than the diameter of focusing type optical transmission bodies 3a... to one 6 of frames of aluminum material or the like. If the transmission bodies 3a... placed in the frame 6 are sandwiched along the grooves 8a... by way of distance pieces 5 of the specified thickness by the frame 6 and frame 4 and adhesives 7 are filled in the spacings, then the focusing type transmission array used for exposure of copying machines, etc. is readily produced with high accuracy.
