た。 In conventional image forming apparatuses, when recording paper jams, the front side wall of the image forming apparatus main body (the side wall having a plane perpendicular to the photoconductor drum axis) is opened and the jammed recording paper is removed. The paper was removed.
しかしながら、記録紙は感光体ドラムの軸線と
直角方向に移動するものであるから、紙詰りが生

稜線部分がひつかかりうまく取り除けない場合が
ある。 However, since the recording paper moves in a direction perpendicular to the axis of the photoreceptor drum, when a paper jam occurs, the recording paper wrinkles so that a ridge line is formed parallel to the axis of the photoreceptor drum. Therefore, as mentioned above, even if you open the front side wall and remove the recording paper,
Sometimes the ridge line gets stuck and cannot be removed properly.
本考案はかかる難点に鑑みてなされたもので、

This is a corotron for separation to be peeled off from the photoreceptor drum 4. Reference numeral 15 denotes a cleaning device for removing toner remaining on the photosensitive drum 4 that has not been completely transferred, and is provided with a blade 16 for stripping off the residual toner and a roller 18 for conveying the stripped toner to a storage container 17. Reference numeral 19 denotes a static elimination lamp that eliminates residual charges on the photosensitive drum 4. 20 and 20 are feed rollers for manual paper feeding provided in the manual paper feeding section 1, and 21 and 22 are fixed guide plates for guiding the copy paper 13. 23 is the fixed guide plate 2
1 and 22, and is rotatable about a support shaft 24 provided downstream. The movable guide 23 is composed of two guide plates, and the copy paper 13 is sandwiched between the two guide plates. 26 is a stopper of the movable guide 23. Reference numerals 25, 25 denote register rollers located downstream of the movable guide 23, which re-feed the copy paper 13 fed by the feed rollers 20, 20 to the transfer section in a timely manner. The automatic paper feed section 2, manual paper feed section 1, register rollers 25, 25, and paper feed guide 2 are integrated to form a unit. A paper feed cassette 27 loaded with copy paper 13 is removably attached to the automatic paper feed section 2. Reference numeral 28 denotes a pushing arm that presses the copy paper 13 against a feed roller 29 for automatic paper feeding through a through hole 27' provided at the bottom of the paper feed cassette 27. rotationally biased in the direction. Reference numerals 31 and 32 are fixed guide plates provided upstream and downstream of the register rollers 25 and 25, respectively. 33 is a vacium conveyor provided downstream of the separation corotron 14;
The copy paper 13 on which the toner image has been transferred is transferred to the fixing roller 3
4.34. 35 is a vacuum unit that supports the vacuum conveyor 33. The unit consisting of the manual paper feed section 1 and the like and the vacuum unit 35 are integrally constructed and fixed on a slider 36 which is slidably mounted on the inner bottom of the copying machine main body 3. 37,3

Reference numeral 38 denotes a lock lever provided on the manual paper feed section 1, and its upright portion 38'' engages with an engagement hole 3' provided in the copying machine main body 3.One end of 39 is connected to the engagement hole 3' provided in the copying machine main body 3. An externally protruding operating lever with the other end and the lock lever 3
8 are connected by a connecting lever 40. The lock lever 38 and the operating lever 39 are rotatably supported by support shafts 38' and 39' fixed to the main body 3 of the copying machine, respectively. Further, the operating lever 39 is biased with rotational force in the clockwise direction by the torsion spring 41.
次に、複写紙１３が紙詰りを生じた場合の処理
方法について説明する。先ず、前記作動レバー３

８″は前記係合孔３′との係合関係が解除される。 Next, a method for handling a paper jam in the copy paper 13 will be described. First, the operating lever 3
9 is pushed up in the direction of arrow B against the torsion spring 41. Then, the actuating lever 39 rotates counterclockwise about the support shaft 39', and this actuating lever 3
The lock lever 38 connected to the lever 9 via the connecting lever 40 is rotated counterclockwise about the support shaft 38'. Therefore, the upright portion 3 of the lock lever 38
8'' is disengaged from the engagement hole 3'.
その状態で、給紙部を右方向矢印Ａ方向に引き

イド２３を回転させた後に形成される開口より詰
つた複写紙１３を取り出すことができる。 In this state, when the paper feed section is pulled out in the rightward arrow A direction, the manual paper feed section 1, automatic paper feed section 2, and vacuum unit 35 move rightward together with the slider 36, as shown in FIG. As shown, it is pulled out from the copying machine main body 3. and,
If a paper jam occurs between the manual paper feed section 1 and the register rollers 25, 25, the movable guide 23
By rotating counterclockwise to the position shown by the dashed line, the jammed copy paper 13 can be taken out from above. Similarly, if a paper jam occurs between the automatic paper feeder 2 and the register rollers 25, 25, if the movable guide 23 is rotated, the opening formed after the movable guide 23 is rotated can be removed. The more jammed copy paper 13 can be taken out.
このようにして、紙詰りを生じた複写紙１３を
取り除いた後、給紙部を複写機本体３内に押込め
ば、前記ロツクレバー３８の起立部３８″と係合
孔３′が、トウシヨンバネ４１の張力により再び
係合することになる。 After removing the jammed copy paper 13 in this way, if the paper feed section is pushed into the copying machine main body 3, the upright portion 38'' of the lock lever 38 and the engagement hole 3' will be aligned with the torsion spring 41. The tension will cause them to re-engage.
なお、以上は電子複写機について詳しく説明し
たが、本考案は他にも種々の画像形成装置（例え
ばLEDプリンタ等）に適用し得るものである。 Although the electronic copying machine has been described in detail above, the present invention can be applied to various other image forming apparatuses (eg, LED printers, etc.).

大きな力を要せず、ジヤムした複写紙の取り出し
が容易にできる。 As described above, according to the present invention, even if a paper jam occurs on the downstream side of the manual paper feed section, the jammed copy paper can be immediately removed by rotating only the movable guide. Therefore, the jammed copy paper can be easily removed without requiring much force to remove the jam.
また、手差し給紙部と自動給紙部を、一体的
に、感光体ドラムの軸線と直角方向に引出すもの
であるから、記録紙を取り除く際に、しわの稜線
部分がひつかかる虞れはない。 In addition, since the manual paper feed section and automatic paper feed section are pulled out as a unit in a direction perpendicular to the axis of the photoreceptor drum, there is no risk of the wrinkled ridge line getting caught when removing the recording paper. .
