Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は複写機に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a copying machine.
(技術背景)
上記の複写機の給紙対象として、複写用の複写紙と被複
写用の原稿とがある。そして、油記複写紙の給紙には、
多数の複写紙を収容したカセットケースを給紙部に装填
して、該ケース内の複写紙を1枚ずつ順次自動給紙させ
るカセット給紙の形態と、手差し給紙部に供給された複
写紙を自動給紙する手差し給紙の形態とがあり、かつ、
機種によっては手差し給紙専用のものもある。(Technical Background) The paper feed objects of the above-mentioned copying machine include copy paper for copying and original documents for copying. And for feeding oil copy paper,
A cassette paper feeding mode in which a cassette case containing a large number of copy papers is loaded into a paper feeding unit and the copy papers in the case are automatically fed one by one, and copy paper supplied to a manual paper feeding unit. There is a manual feed mode that automatically feeds paper, and
Some models are only for manual paper feeding.
一方、前記原稿の給紙には、原稿押えを開閉して原稿を
1枚ずつ人為的に原稿台上に給紙する人為給紙の形態と
、原稿台の横−側に給紙装置を設けて、当該給紙装置の
手差し給紙部に供給された原稿を自動給紙する手差し給
紙の形態とがある。On the other hand, in order to feed the original, there are two methods: artificial feeding, in which the originals are artificially fed one by one onto the document table by opening and closing the document presser, and a paper feeding device installed on the side of the document table. There is a form of manual paper feeding in which a document supplied to a manual paper feeding section of the paper feeding device is automatically fed.
そして、上記複写紙や原稿(以下、紙と称する)を手差
し給紙する形態をとるための給紙装置として、手差し給
紙部に1枚ずつ紙を供給させて、これを複写動作に連動
して給紙させる所謂手差しタイプのものと、手差し給紙
部に多数の紙を供給させておいて、複写動作に連動して
最上位の紙を順次1枚ずつ給紙させる所謂マルチタイプ
のものとがある。Then, as a paper feeding device for manually feeding the copy paper or original (hereinafter referred to as paper), the manual feeding section feeds paper one sheet at a time, and this is linked to the copying operation. There are the so-called manual feed type, in which the paper is fed by the machine, and the so-called multi-type, in which a large number of papers are fed into the manual paper feed section, and the topmost paper is fed one by one in conjunction with the copying operation. There is.
そこで従来は、手差しタイプの給紙装置装備の複写機と
マルチタイプの給紙装置装備の複写機とを生産している
が、ユーザーの希望に即応できるようにする上で、上記
二種の複写機を十分にストックしておく必要があり、且
つこれに伴って保管場所を広く要する欠点があったので
ある。Therefore, in the past, copying machines equipped with a manual paper feed device and those equipped with a multi-type paper feed device were produced, but in order to be able to quickly respond to the wishes of users, the above two types of copying machines were manufactured. It was necessary to keep a sufficient stock of machines, and this required a large amount of storage space.
あるいは、ユーザーサイドにおいて、一方の給紙タイプ

能の給紙形態しかとることができず、または、二通りの
給紙タイプのM&能を選択できるように2台の複写機を
人手するには、余りにも不経済であるばかりか設置場所
を広く要する欠点がある。Alternatively, on the user side, if one paper feed type (a) type is obtained, unless the user obtains the other paper feed type (a type), only the paper feed form with the functions provided by the selected paper feed type will be used. However, it is not only uneconomical to manually install two copying machines so that two paper feeding types and M&functions can be selected, but also requires a large installation space.
本発明は、上記の実情に鑑みて成されたものであって、

可能に構成した点に特徴を有する。The present invention has been made in view of the above circumstances, and
The purpose is to provide a copying machine that can quickly respond to the user's requests in terms of functionality while reducing the number of copies in stock by half, or that allows the user to select the paper feed function in an extremely economical manner. Therefore, the copying machine according to the present invention includes a paper feeding mechanism having a function of preventing double feeding, and a forward feed roller that feeds paper to the paper feeding mechanism,
and a multi-unit comprising a paper feeding input means provided in the paper feeding mechanism via a clutch, and a transmission mechanism provided between the means and the forward feed roller, and a manual paper feeding device in which the input means is connected in series. The present invention is characterized in that a manual feeding unit equipped with a roller can be selectively attached to a paper feeding section of the main body of the copying machine.
