（産業上の利用分野）
本発明は、画像形成袋｛在、特に、紙搬送部に発光部を
持った構成の複写装置等の画像形成装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an image forming bag, and particularly to an image forming apparatus such as a copying apparatus having a light emitting section in a paper conveying section.
従来、第４図に示すように複写装置に用いられる紙搬送
系（給紙部・搬送部・排紙部）は、紙の搬送がスムーズ
に行われるように、ストレートバス方式や紙搬送路長を
短くするような工夫をして、紙詰まりを極力少なくする
構成となっている。Conventionally, as shown in Fig. 4, the paper conveyance system (paper feed section, conveyance section, and paper ejection section) used in copying machines has been designed using a straight bus system or a long paper conveyance path to ensure smooth paper conveyance. The structure is designed to minimize paper jams by shortening the length of the paper.

う。ジャムの発生率を減少させるには、紙搬送路の構成
を単純化する必要があり、両面・多重等の多機能化や小
型化を実現することが出来なくなる。Recently, copying apparatuses have become larger and faster, and on the other hand, paper conveyance paths have become more complex as they have become smaller. As described above, the complicated structure of the paper conveyance path leads to an increase in the incidence of paper jams (hereinafter referred to as jams). In order to reduce the occurrence rate of jams, it is necessary to simplify the configuration of the paper conveyance path, which makes it impossible to realize multiple functions such as duplexing and multiplexing, and miniaturization.

間がはふけるようになった。In addition, as copying machines became more multi-functional and smaller, the paper transport path became multifunctional, and once a jam occurred, each part of the copying machine had to be manually removed to remove the jammed paper. . Jam detection devices have been installed that let you know where a jam has occurred, saving you the trouble of searching for it.

れる恐れがあった。(Problem to be solved by the invention) However, since copying machines use photoreceptors, they are constructed to prevent light from entering as much as possible, so when a jam occurs, you have to grope in the dark to remove the jammed paper. As a result, the safety of the copying device may be compromised due to dirt from toner or oil, injury from the device, or burns from the fuser.

飛躍的に高めることを可能にした。According to the present invention, in an image forming apparatus having a paper feeding section, a paper conveying section, and a paper discharging section, an illumination member for illuminating the paper conveying section is provided inside the image forming apparatus. While eliminating these drawbacks, it has also made it possible to dramatically improve the safety of copying machines, etc.

範囲外であり、公知の方法でよい。FIG. 1 is a sectional view of a copying apparatus according to an embodiment of the invention. Paper of a specified size is fed from the manual feed tray 17, upper cassette 18, or lower cassette, and is sent out by registration rollers 27 in synchronization with the image on the photoreceptor drum 29, and the image is transferred to the paper by the transfer charger 25. It is transferred, separated by the separation charger 24 and the separation claw 23, passed through the conveying section 5, fixed by the fixing device 4, and then transferred to the paper output tray 3.
The paper is ejected at 1. . Copying process (charging, exposure, development,
Transfer, separation, fixing, cleaning, etc.) methods are outside the scope of the present invention, and known methods may be used.

容易に取り除くことが出来る。照明の位置や数は各装置
に最適の場所に必要な数だけ配置することが望ましい。If a jam occurs during copying, a jam detection lamp (not shown) on the operation panel lights up to notify the user of the occurrence of a jam, and at the same time, the apparatus comes to a halt. To remove jammed paper, press the light switch on the operation panel, and the lights 28a''-d in the copying machine will light up, allowing you to easily remove jammed paper.The position and number of lights are optimal for each machine. It is desirable to place them in the required number of locations.

よって、複写中に間違りて照明スイッチを押しても問題
ない。The light switch works in conjunction with opening/closing parts such as the front cover of the copier.
It may be configured so that it can be turned on only when it is open, or it may be configured so that it is automatically turned on. Thereby, there is no problem even if the light switch is pressed by mistake while copying.

光体疲労が少ない。Further, a shutter may be provided to protect the photosensitive drum in conjunction with a lighting switch or a device opening/closing member (not shown). This prevents deterioration of the photosensitive drum's memory due to illumination, and when a shutter to protect the photosensitive drum cannot be provided as the device becomes smaller and more complex, A lighting device with wavelengths may be installed. For example, FIG. 2 shows the spectral sensitivity of a photosensitive drum. In the case of an OPC photoreceptor, its sensitivity range is from 500 to 630 nm in wavelength, so an illumination lamp with a wavelength of 450 nm may be used, resulting in less fatigue of the photoreceptor.
また、ａ−３ｉの場合は、感度領域は可視光全域にわた
るが、６００ｎｍ以下の波長に対しては感光体疲労がな
いことが知られており、６００ ｎｍ以下の照明ランプ
を用いればよい。In the case of a-3i, the sensitivity range covers the entire visible light range, but it is known that there is no photoreceptor fatigue for wavelengths of 600 nm or less, and an illumination lamp of 600 nm or less may be used.

ッター等により遮へいする必要がある。As another embodiment of the invention, the light source for exposure may be guided to each part by a mirror or an optical fiber, so that a new illumination device is not required. However, since an exposure lamp is used, only the optical path to the photosensitive drum needs to be blocked by a shutter or the like.
照明が点燈するようにして、トナー補給その他の時には
照明がつかないようにシーケンス制御を行っている。Sequence control is performed so that the lighting is turned on, but not during toner replenishment and other times.

し、すみやかにジャム紙を取り除くことかできた。According to experiments, when the above-mentioned sequence control device and lighting device are added and a microswitch is provided on the front cover, and a jam occurs in the duplex unit 30, the operation panel indicates that a jam has occurred in the duplex unit. The notification display was lit, and when the front cover was opened, only the lamp 28-d was lit, and the jammed paper could be removed quickly.

性・操作性が飛躍的に増す。As explained above, the simple configuration of incorporating a lighting device into the image forming apparatus increases the recovery of jammed paper.
This dramatically increases safety and operability when inspecting the inside of the device, such as when jamming or during service.
