プロセスについて述べたが、上記用紙搬送を行うために
、以下の準備が必要である。Next, the operation will be explained. A toner image is formed on the continuous paper (1) by a constant feed tractor (2) with the same precision as the circumferential speed of the photoconductive drum +31. Next, the continuous paper il+ is printed by fixing and fixing the toner image on the continuous paper (1) using fixing means such as heating and pressure using a fixing device (4). Furthermore, the continuous paper il+ is regulated by a paper transport path by a guide plate (5) and is transported by a discharge tractor (6) that generates a discharge driving force. Furthermore, the printed continuous paper il+ has swing fins (7).
The folding stacker (8
). The above has described the process during continuous printing, but in order to carry out the above paper conveyance, the following preparations are required.

Pulling out continuous paper fli for a distance longer than the conveyance distance (
Do lots. Next, the continuous paper (
1) To transfer the paper, move the fixing device (41) out of the way and carry out a loading operation in which the starting edge of the continuous paper +1 is manually fed along the guide plate (5). Next, front loading is completed by stretching the continuous paper (1) on the discharge tractor (6) so as not to cause wrinkles.
従来の用紙搬送装置は以上のように構成されていたので
、用紙の装填作業は予め用紙を引き出し、スタッカまで
用紙を引き回わすことが必要で、用紙の折りたたみに有
害な用紙及び用紙始端にシワ。Conventional paper conveyance devices were configured as described above, so when loading paper, it was necessary to pull out the paper in advance and route the paper to the stacker. .

保による印刷装置の大形化、さらには連続用紙の終端部
が定着器とこすれ印字が汚れるなどの問題点があった。Damage such as folding is likely to occur, and paper is unavoidably wasted during the loading operation. There were other problems, such as an increase in the size of the device and the fact that the end of the continuous paper would rub against the fixing device, resulting in smudged prints.
この発明は上記のような問題点を解消するためにかされ

する。In the paper conveying device according to the present invention, the starting edge of the continuous paper is transported with the paper guide adsorbed to the paper guide, so that lifting of the starting edge due to curling of the continuous paper is prevented, and similarly, the starting edge of the continuous paper is Since lifting is prevented, damage to the paper such as getting caught at bends in the conveyance path, rubbing the printed surface, etc. is eliminated. Furthermore, during continuous printing when the above effects are not required, the drive mechanism that retreats from the paper transport path prevents contact between the paper guide and the continuous paper, and there is no wear on the paper guide suction transport mechanism. Furthermore, even in the event of an unexpected accident, work space is secured without interfering with work.

上記ハリの座屈荷重以下にすればよい。Next, the continuous paper starting end α° C. is transported to the stacker (8). Fixed length feed tractor (2
) When the continuous paper starting edge αυ is ejected from
Since the continuous paper starting end αυ is in the position (A) (see FIG. 2) where the paper I) is not caught, the continuous paper starting end αυ is easily conveyed to the upper surface of the paper guide (1). Next, since the fan (to) is driven in the exhaust direction, the continuous paper i1) and its starting end α°C are sucked into the paper suction hole (to), and the conveyor belt on the upper surface of the paper guide screen is Being pushed. This is set at a speed (54
Since the conveyor belt (B) is driven by the conveyor belt (UP), the pressing force against the conveyor belt generates a frictional force in the conveyance direction due to the speed difference mentioned above. Therefore, the continuous paper fi+ transports the continuous paper starting edge OD to the very front of the duct formed by the guide plate (5) and the front end guide (Foundation) without causing any wrinkles, folds, or deflections on the upper surface of the paper guide 1''. Although there is no suction conveying force from the guide plate (5) and the front end guide Q1), since the conveyor belt (A) slightly protrudes from the upper surface of the paper guide pan, the paper conveyance direction and perpendicular The cross section of one page has a wavy cross section with the pitch at which the conveyor belt slope is arranged, and the bending rigidity in the sheet conveyance direction is high, so that the sheet can be reliably conveyed to the guide surface called the guide plate (6). and rear tip guide (
The conveyance in the duct is carried out by the guide plate (the frictional force exerted by the starting end of the continuous paper in the duct against the continuous paper (l) having a span of 61). It should be less than the buckling load of the firmness.

再ひ用紙ガイド（１）は退避位置（Ｂ）に戻る。When the last end 0 of the continuous paper fli is fed out from the fixed length feed tractor (2), the paper guide IA returns to the transport position (A) again. This is because the unfixed toner image (not shown) on the continuous paper [1] is gently conveyed to the fixing device (4) at a certain conveyance speed or less, thereby eliminating waste paper at the end a2 of the continuous paper fi. In this way, if the end (a) of continuous paper m is stored in the stacker (81),
The paper guide (1) returns to the retracted position (B).
これは、連続用紙（１）の印刷が終了し、次の作業。This means that printing of continuous paper (1) has been completed and the next work is to be done.
