Further, in order to converge the emitted light of the ultraviolet lamp as desired, the mirror must accurately set the relative positional relationship with the ultraviolet lamp.

In the past, as a positional alignment operation between the ultraviolet lamp and the mirror, a dedicated positional relationship between the mirror (actually the holder of the mirror) and the ultraviolet lamp (actually, the holder of the ultraviolet lamp) was created. In many cases, the jig is used to fix each part in a state in which the jig is used for the assembly work, when the lamp or the mirror is replaced, or when the lamp or the mirror is cleaned.

Therefore, in the above-described configuration, the mirror inserting member that supports the mirror of the mirror holder is disposed over the entire circumferential end portion in the longitudinal direction of the mirror, thereby reducing the extraction efficiency of the reflected light.

Moreover, since the holder for holding the mirror is disposed on the entire back side of the reflecting surface of the mirror, the back side of the reflecting surface of the mirror is hidden by the holder and is visible by infrared rays or a part of the radiation emitted from the ultraviolet lamp.

The motor 4b is supported by the motor holding plate 46, and is disposed at a position below the air blowing unit 2 outside the space surrounded by the baffle 4a and the casing 4c. At the upper portion of the installation position of the motor 4b, the motor holding plate 46 is extended to prevent the life of the motor 4b or the connected member from being shortened due to ultraviolet rays leaking from the vicinity of the electrode 6a of the ultraviolet lamp 6 located directly above.

The fixing member 42 attached to the end portion of the baffle 4a is attached to the frame 4c through the rotating shaft 41 of the motor 4b of the speed reducer.

Further, the fixing member 43 attached to the end opposite to the side where the fixing member 42 is present also includes a rotating shaft 43a that penetrates the vertical wall of the frame 4c and is fixed to the rotating shaft holding plate 44. The bearing 45 is rotatably supported.

The rotating shaft 41 and the rotating shaft 43a are disposed on a common rotating shaft core, and the fixing member 42 and the fixing member 43 are mounted near the lower end of the shutter 4a in the standing posture, and are driven by the driving of the motor 4b. The board 4a is remotely driven.

By the rotation of the motor 4b, the shutter 4a is driven to switch to the standing posture indicated by the solid line in Fig. 2(b) and the substantially horizontal posture indicated by the two-dot chain line.

The standing posture indicated by the solid line is the opening posture of the shutter 4a as described above, and the shutter 4a allows the ultraviolet light emitted from the ultraviolet lamp 6 to be emitted from the ultraviolet light-emitting window 10 located directly below the shutter unit 4 in the open posture. The outside of the frame 1 is emitted.

On the other hand, the substantially horizontal posture indicated by the two-dot chain line in Fig. 2(b) is the closed posture of the shutter 4a, and in the closed posture, the shutter 4a is in a posture of protruding toward the ultraviolet lamp 6 side. The shutter 4a blocks the ultraviolet rays emitted from the ultraviolet lamp 6 in its closed position, and prevents ultraviolet rays from being emitted from the ultraviolet emission window 10 to the outside of the apparatus casing 1.

The ultraviolet ray exit window 10 is formed as a rectangular opening on the bottom plate 22 forming the one side surface of the apparatus casing 1. In the ultraviolet light-emitting window 10, a light-transmitting plate 11 made of quartz that transmits ultraviolet rays is attached so as to cover the ultraviolet light-emitting window 10.
