があつた。 BACKGROUND ART Conventionally, in order to inspect the inner surface of a pipe, a welded portion, etc. of a long-distance piping, a capsule containing a built-in camera is pneumatically transported to photograph and inspect the inner surface of the pipe and the welded portion. In this case, if the photographing window becomes dirty due to dust thrown up during pneumatic transport, clear images cannot be obtained, so the dust is removed using a wiper. However, since this wiper is made of rubber, it has drawbacks such as damaging the glass surface when dry and increasing the wiper power.
この考案は、上記欠点を解消できるようにした

いる。 An embodiment of this invention will be described below with reference to the drawings. In the figure, 1 is a pipe to be inspected, and 1a is a welded portion thereof. Seal cup 3 for camera capsule 2
is attached so that the camera capsule 2 is gently air-fed from the left to the right in the figure due to the pressure difference before and after the seal cup 3. A camera unit 5 including a camera 4 is rotatably provided in the camera capsule 2. A photographing window 6 for direct viewing inside the tube is provided at the rear end of the camera section 5, and a photographing window 7 for side viewing for detailed inspection of welded parts 1a and the like is provided on the side. Glasses 9 and 10 are attached to these photographic windows 6 and 7, respectively. In the case of side-view photography, the camera section 5 is rotated so that the welded portion 1a can be inspected over the entire circumference via the mirror 8.
直視用撮影窓６のガラス９に対しワイパ１１が

けた軟質材１４に注入する。 A wiper 11 is provided on the glass 9 of the direct viewing photographing window 6, and this wiper 11 is attached to the tip of an arm 12 that is swung by a motor 13. A soft material 14 is attached to the surface of the wiper 11 that comes into contact with the glass 9. As the soft material 14, for example, a soft cloth coated with silicone, tanned deerskin, or the like is used. This soft material 14 has a feeding device 1.
Volatile liquid is supplied by 5. The feeding device 15 is a storage cylinder 16 for volatile liquid.
and an injection tube 1 provided along the arm 12
7, the piston of the storage cylinder 16 is moved little by little to inject the volatile liquid into the soft material 14 attached to the wiper.

ことができた。 With the above configuration, the soft material 14 attached to the wiper
is always moist. This allows smooth operation without damaging the surface of the glass 9. When the wiper operates, it slightly wets the surface of the glass 9, but it evaporates in an instant, so a problem-free image can be obtained. In addition, since the photographing window 6 is installed at the rear of the capsule 2, there is less dust adhesion, and the wiper 11 has a width of 10~20 mm.
Good results could be obtained simply by operating at a feeding interval of m.

態に保つようにする。 The wiper 2 is attached to the glass 10 of the side viewing window 7.
1 is provided, and this wiper 21 is attached to a screw shaft 22 which is reversibly rotated by a motor 23 via a reversing mechanism so as to reciprocate over the glass 10. A soft material 24 is attached to the surface of the wiper 21 that contacts the glass 10. The soft material 24 is, for example, a lubricant (hikubutene disulfide).
Rubber coated with Then, as in the case of the above-mentioned direct viewing photographing window, the soft material 24 is kept constantly moist.
