Abstract
본원은 흑칠판, 백칠판 등에 쓰인 문자 등을 자동적으로 소거하는 소거 장치에 관한 것이다. 본원의 목적은, 소거 롤러에 부착한 가루를 털어내는 것과 거의 동시에 집분실내에 빨아들이게 해서 흡분 효율을 높히고, 필터에 흡수되지 않았던 가루를 필터에 흡수되기 까지 케이스 본체내에서 순환시키고, 1개소에 가루를 축적시키지 않는 구조가 간단하고 매우 염가인 소거장치를 체공하는 것을 목적으로 한다. 그에따른 구성으로는, 소러 롤러(45,47)에 부착한 가루는 돌출부(52,53)에 의해서 털어내어지는 것과 거의 동시에 분말 흡입구(57,59)에서 흡입되고 필터(69)에 흡수된다. 필터 (69)에 흡수되지 않았던 가루는 흡인 장치(79)에 의해 상부 수용실(21)내에 배출되고 연통개구(88)를 거적서 하부 수용실(50)에 보내지며 재차 소거롤러(45,47)에 부착한다. 소거 롤러에 부착한 가루는 필터에 흡수되기까지 케이스 본체내를 순환한다. 연통개구(88)를 거쳐서 하부 수용실(50)에 보내지며 재차 소거 로러 (45,47)에 부착한다. 소거 롤러에 부착한 가루는 필터에 흡수되기 까지 케이스 본체내를 순환한다.The present invention relates to an erasing device for automatically erasing characters used in blackboard, whiteboard, and the like. The object of the present application is to sift the powder attached to the elimination roller into the collecting chamber at about the same time to increase the absorption efficiency, and to circulate the powder not absorbed by the filter in the case body until it is absorbed by the filter. It is an object of the present invention to provide a scavenging device which has a simple structure that does not accumulate powder and is very inexpensive. As a result, the powder adhering to the sorrel rollers 45 and 47 is sucked into the powder inlets 57 and 59 and absorbed into the filter 69 at substantially the same time as being shaken off by the protrusions 52 and 53. The powder that has not been absorbed by the filter 69 is discharged into the upper receiving chamber 21 by the suction device 79, and the communication opening 88 is collected and sent to the lower receiving chamber 50, and the elimination rollers 45 and 47 are again provided. ) The powder adhering to the eraser roller circulates in the case body until it is absorbed by the filter. It is sent to the lower housing chamber 50 via the communication opening 88 and is again attached to the erasing rollers 45 and 47. Powder adhering to the erasing roller circulates in the case body until it is absorbed by the filter.
