Claims (1)

[Scope of Claim for Utility Model Registration] (1) In an apparatus for manufacturing a tape-type optical fiber cable in which a plurality of tape-type core wires are fitted in an overlapping manner into an outer peripheral spiral slot of a central shaft passing through a twisting die, One end in the width direction of the tape-shaped core wire to be fitted on the outermost side is colored with a specific color, and the above-mentioned color is applied to the outlet side of the twisting die at a position corresponding to the point through which the colored one end passes. A detection section of a color mark sensor that detects a specific color is disposed, and the color mark sensor has means for discriminating the specific color and issuing a stop signal when detecting a color other than the specific color, and the color mark sensor is provided with a means for emitting a stop signal when detecting a color other than the specific color. A manufacturing device for tape-type optical fiber cable, characterized in that a stopping mechanism is connected to the manufacturing device to stop the manufacturing device. (2) Color one end of each tape-type core wire in the width direction with a different specific color, and set a specific color for detection at each location corresponding to the portion where each fiber core wire passes just before dropping into the die entrance. A utility model in which a detection section of a sub-color mark sensor is arranged, and each sub-color mark sensor has a means for discriminating between each specific color and other colors and issuing a stop signal when detecting a color other than the specific color. An apparatus for manufacturing a tape-type optical fiber cable according to claim 1.
