〔産業上の利用分野〕
本発明は２分割可能な構造を有する複写機に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine having a structure that can be divided into two.
ジャム状聾となった給送不能の記録紙を取出し除去する
ためとか、搬送系統や画像形成の各部の点検整備を容易
ならしめるものとして、記録紙の搬送面を境とし上部本
体を蝶番によって上方に開放出来るよう構成したシェル
タイブと呼ばれる２分割式複写機が知られている。In order to remove jammed recording paper that cannot be fed, or to facilitate inspection and maintenance of the conveyance system and image forming parts, the upper body is moved upward with a hinge from the recording paper conveyance surface. A two-part copying machine called a shell type copying machine is known, which is configured so that it can be opened into two parts.
シェルタイブによれば複写機の内部機構のレイアウトを
基本的に変更することなく２分割が可能であり、また上
部本体を開放した時でも特に床面積を必要としない等の
利点があるが、搬送面が全域にわたって均等に開放され
ず蝶番近くの搬送面の開口が僅小であるため、その付近
に発生した記録紙のジャム処理が依然やりづらいという
欠点がある。According to Shell Type, it is possible to divide the copier into two parts without fundamentally changing the layout of the internal mechanism, and it also has the advantage of not requiring any particular floor space even when the upper body is opened. Since the opening on the transport surface near the hinge is not evenly opened over the entire area and the opening on the conveying surface near the hinge is very small, it is still difficult to clear the jam of recording paper that occurs in that area.
また傾斜した上部本体の原稿載置台からは原稿が滑落し
床上に落下して汚損する危険もあるので上部本体の開放
の際にはその都度原稿と原稿載置台から取外す必要もあ
る等取扱いの点で多くの難点を有している。In addition, there is a risk that the original may slide off the original table on the slanted upper body, fall onto the floor, and become dirty, so it is necessary to remove the original from the document table each time the upper body is opened. It has many drawbacks.
これに反し、給紙部や排紙部を複写機本体より独立した
ユニットとして構成し、ジャム処理等に際してはこれら

如く原稿を滑落する心配はｆよいが、前記各ユニ、トを
引出すために高価なレール部材とガイド部材を必要とし
、複写機の価格に大きな負担を加える結果となっている
。On the other hand, split-type copying machines, in which the paper feed section and paper ejection section are configured as separate units from the main body of the copying machine, and these units can be pulled out to widen the conveyance surface when handling jams, etc., always keep the original Since the mounting table is placed in a horizontal position, there is no need to worry about the original slipping off like in the case of the shell type mentioned above, but it requires expensive rail members and guide members to pull out each unit. This has resulted in adding a large burden to the price of copying machines.
本発明は、充分な搬送面の開放によってジャム処理等が
容易であり、かつ原稿の滑落等を伴わない２分割式複写
機の提供を目的としたものである。SUMMARY OF THE INVENTION The present invention aims to provide a two-part copying machine that facilitates jam removal by sufficiently opening the conveyance surface and prevents documents from falling off.
本発明は、複写機の機能部分を画像形成プロセスに関連
するユニ、トと記録紙搬送に関連するユニットの２プロ
、りに分割し、それぞれのプロ。In the present invention, the functional parts of a copying machine are divided into two units: a unit related to the image forming process and a unit related to recording paper conveyance.

によって達成される。The main body of the copying machine is connected to the main body of the copying machine by a hinge or the like so that it can be opened and closed in the horizontal direction.
At least the photoreceptor, charging, exposure system, development,
It is divided into a block that handles cleaning etc. as an integrated unit, and a block that handles at least the paper feed, transport system, transfer, separation, fixing, etc. This is achieved by a copying machine that is characterized by:
本発明の複写機の１実施例を第１図および第２図に示す
。One embodiment of the copying machine of the present invention is shown in FIGS. 1 and 2.
本発明の複写機は、や＼大型で未習に定置される右側本

せしめている。The structure of the right side main body 1 includes a document mounting table 1 that holds a document.
1. Optical system 12 for exposing and scanning the document surface; Photosensitive drum 1
4, its charging electrode 13, and a developing device that converts the latent image on the photosensitive drum 14 formed by the optical system 12 into a toner image! In the present invention, the toner image transfer surface of the photosensitive drum 14 is located at the left opening of the right side main body 1.

。Therefore, the recording paper that has completed copying after passing through the fixing roller 27 is deflected in the horizontal direction and passes through the paper ejection roller 28 to the side surface 1.
The paper is discharged onto a paper discharge tray 29 provided therein. In this embodiment, the paper was ejected to the side of the machine, so the sheet was deflected horizontally after fixing.
In that case, a paper discharge tray may be provided as shown in FIG.

式の複写機も本発明に含まれる。In the above embodiment, the photosensitive drum 11 provided in the right main body 1 is configured to rotate clockwise.1. The photoreceptor drum 14 is rotated substantially counterclockwise.
The developing device 16 is arranged on the upper side, the charging electrode 13 and the cleaning device 15 are arranged on the lower side, and also in the left main body 2,
It is also possible to reverse the top and bottom configuration so that the recording paper conveyance path moves from top to bottom, and such a two-part copying machine is also included in the present invention.
本発明により、原稿を載置したま一開放が可能でかつ記
