本発明は、複写機における集束性光伝送体の防塵装置に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust prevention device for a convergent light transmission body in a copying machine.
従来、複本機における集束性光伝送体の防塵手段として
は、シャッタ機構を用いるもの、静電気を利用するもの
、エア7o−を利用するもの、あるいは防塵ガラスを便
用するもの等があるが、これらの防塵手段は、いずれも
種々の問題点があった。Conventionally, there have been methods for preventing dust on the convergent optical transmission body in a multi-function machine, such as those using a shutter mechanism, those using static electricity, those using air 7o-, and those using dust-proof glass. All of these dustproof measures had various problems.

の悪いコピイを得る等の問題点がある。In other words, those that use a shutter mechanism as a dust prevention means have a complicated structure, an increased number of parts, high cost, and lack of reliability. In this case, the electric charge not only affects the photoreceptor in the copying machine and degrades the image quality, but also has the drawback of causing dust of opposite polarity to adhere to the focusing light transmitter. The dust-proofing efficiency of the equipment used differs depending on the structure near the converging light transmitter, and therefore, in order to improve the dust-proofing efficiency, it is necessary to install a dedicated air duct, fan, etc., which increases the cost. In addition, in the case of using dustproof glass as a dustproofing means, although it is useful for dustproofing the converging light transmitter, if the dustproofing glass itself gets dirty, the dustproofing function will not be fulfilled. Therefore, some proposals have been made in which the dust-proof glass is removably attached, and if the dust-proof glass gets dirty, it can be removed and cleaned. There are problems such as forgetting to attach the lens and obtaining copies with poor resolution due to the lens being out of focus.
本発明は、上記事情に鑑み案出されたものであって、簡

なる亀のである。As described above, the dustproof device for a converging light transmitting body in a copying machine according to the present invention slides the dustproof glass g that faces the image side end surface of the convergent light transmitting body 3 and shields the image side end surface. A cleaning member 16° 16 is provided movably, and is provided at the end of the convergent light transmitting body 3 in the sliding direction of the dustproof glass 8, and is in sliding contact with the upper and lower surfaces of the glass base 9 of the dustproof glass g. From there, the image side end surface of the convergent light transmitting body 3 is covered with a dustproof glass 8.
Not only can dust-proof glass 8 be shielded and prevented from getting dirty, but if the dust-proof glass 8 is dirty, by sliding the dust-proof glass ε, both upper and lower surfaces of the glass base 9 of the dust-proof glass 8 can be cleaned with the cleaning member 16. Cleaning of the dust-proof glass 8 involves simply sliding the dust-proof glass 8, so there is no risk of damage or installation, like when removing the dust-proof glass 8. This eliminates the need to forget to attach the dustproof glass 8, and also eliminates problems such as forgetting to install the dustproof glass 8, which causes the image plane to shift out of focus and cause poor resolution.
