ず、装置全体が長大化する欠点がある。Problems that the invention aims to solve In the conventional device described above, only a small portion of the ultraviolet light emitted from the ultraviolet lamp of the irradiation device is used because the optical fiber that is the object to be irradiated is thin, and most of the ultraviolet light is scattered. Therefore, the irradiation efficiency is poor, the irradiation time for curing the photosensitive coating material becomes long, and the transport speed of the optical fiber cannot be increased. In order to increase the transport speed, it is necessary to increase the number of irradiation instruments, which has the drawback of increasing the length of the entire apparatus.

is a rotary shutter in the form of a hollow cylinder, and consists of an opening portion 4a and a non-opening portion 4b, and the inner surface of the non-opening portion 4b is finished as a reflective surface. 5 is a quartz tube placed in the center of the rotary shutter, inside which the irradiated object,
For example, an optical fiber coated with a photosensitive resin coating passes through it. FIG. 1 shows a light-blocking state, in which the non-opening portion 4b of the rotary shutter 4 is located in front of the irradiation device 1, and the ultraviolet rays from the ultraviolet lamp 3 are blocked. FIG. 2 shows the ultraviolet irradiation state, in which the opening 4a of the rotary shutter 4 is located in front of the irradiation device 1, and the ultraviolet rays from the ultraviolet lamp 3 hit the optical fiber passing through the quartz tube 5, and are directly irradiated. The remaining portion is reflected by the reflective surface inside the non-opening portion 4b and irradiated onto the optical fiber, and when the optical fiber passes through this device, the coating material hardens and becomes an exterior. The rotation direction of the rotary shutter 4 may be a combination of clockwise and counterclockwise directions, or by rotating intermittently in the same direction, the opening portion 4a and the non-opening portion 4b may be alternately positioned in front of the irradiation device 1.

Also, when the opening of the rotating shutter is located in front of the irradiation equipment,
The ultraviolet rays are irradiated onto the irradiated object, and the ultraviolet rays that have missed the irradiated object are reflected by the reflective surface inside the non-opening part of the rotating shutter and irradiated the irradiated object again, increasing the efficiency of UV irradiation and reducing the irradiated object. Photosensitive coating materials and paints can be cured even when the irradiated object is transported at high speed. Further, by arranging the irradiation instruments in a circumferential manner around the irradiation object transport path, the installation space for the apparatus can be reduced.
