拭取紙２７は逆方向に駆動することもできる。Next, the wiping unit 4 according to the present invention will be described. Wiping part 4
Is provided with a roller box 26 having a plurality of chambers 26b having a curved surface portion 26a at the lower portion for accommodating the free rollers 24. The free roller 24 is housed in the roller box via an upper spring 25 in each chamber. 27 is a wipe paper (or cloth) fed from an upper paper feed roll 29, guided by guide rollers 28 in front of and behind the roller box 26, and taken up by a take-up roll 30 provided on the upper part of the machine body 1. The roller box 26 is different from the machine frame 1 in that the water absorbing portion frame 1
Similar to 3, the spring 31 is elastically mounted. The wiping paper 27 can also be driven in the opposite direction.

る。The wiping paper 27 is fed out from the paper feed roll 29 and wound around the guide roller 28 → the free roller 24 ... → The outer peripheral surface of the guide roller 28 to the take-up roll 30. The paper can be used effectively. Further, the upper portion of each free roller 24 is housed in a roller box 26 via a spring 25, and the wiper paper 27 is constantly wiped.
Since it is pressed downward against the floor by its own weight, even if the floor is uneven, the roller 24 moves up and down and the wiping paper 27
Is designed to easily follow uneven surfaces for wiping.
走行用駆動輪５は、吸水部３の横巾よりも内側に位置
し、非除染部を転動しないようになっている。The drive wheel 5 for traveling is located inside the lateral width of the water absorption part 3 so as not to roll in the non-decontamination part.
（作動） 駆動輪５，６を駆動し、ハンドル７をもって所要の除染

掻き寄せ作用を行う。The contaminated water is vacuumed by the water absorbing section 3 of the present invention. Water absorption part 3
The sponge 14 and the porous rubber 15 are pressed by the weight of the machine body, but are not pressed by the rollers 18 and 18 any more.
It sucks up the contaminated water that has been scraped up by. At this time, if the floor surface is uneven, the porous rubber 15 enters this portion, and instead of the squeegee rubber 16, the contaminated water in the concave portion is attracted.
かくして吸水部３で相当程度に汚染水は吸いとられる
が、さらに次の拭取部４において拭取紙２７によって床
面は完全に拭きとられて乾燥する。このとき、フリーロ
ールは床面の凹凸に容易になじみ、完全に床面を拭取る
ことができる。Thus, although the contaminated water is absorbed to a considerable extent by the water absorbing part 3, the floor surface is completely wiped off by the wiping paper 27 in the next wiping part 4 and dried. At this time, the free roll easily fits into the unevenness of the floor surface and can completely wipe the floor surface.
（効果） 洗浄部と、汚染水の吸水部と、床の拭取部とを１台の機
枠にコンパクトに装着し、動力で自由に移動できるよう
にしたので、極めて能率的かつ安全な除染作業を可能と
するものである。(Effect) The cleaning unit, the water absorption unit for contaminated water, and the floor wiping unit were compactly mounted on a single machine frame, and allowed to move freely by power, so extremely efficient and safe removal is possible. It enables dyeing work.
特に本発明の拭取部はローラボックスに収納され、かつ
上下動可能な複数個のフリーロールと、該フリーロール
