おける給紙搬送装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a copy paper detector in the course of paper feeding and conveyance from a paper feed means to a photoconductor, and a conveyance means downstream of the copy paper detector in the conveyance direction. The present invention relates to a sheet feeding / conveying device in a copying machine in which a bend is formed in a copy sheet on the upstream side of the conveying means to correct the leading edge of the bend.

せた状態で撓ませるようにして、搬送途上において複写
紙の先端補正を行なうようにしている。(Prior Art) Generally, in an electrostatographic copying machine, a copy sheet is conveyed in synchronization with driving of an optical system.
For example, when the paper feed roller provided near the paper feed cassette is rotated, the paper feed force may become unstable due to a frictional force between the paper feed roller and the copy paper. May be conveyed in a so-called skewed state in which the sheet is inclined with respect to the conveying direction. Therefore, in a state where the leading end of the copy paper is brought into contact with a stationary conveying means, for example, a nip position of a pair of conveying rollers. The front end of the copy sheet is corrected while being conveyed so that the copy sheet is bent.

れるようにするため、前記時間ｔを比較的大きく設定し
ていた。That is, a copy sheet detector is provided on the upstream side of the pair of conveying rollers, and this detector detects the copy sheet and starts to rotate the conveying roller after a predetermined time t, so that there is no deflection enough to correct the leading edge. It was formed on the upstream side of the pair of conveying rollers. In the conventional copying machine of this type, the time t is set to be relatively large so that the bending is necessarily formed on the upstream side of the conveying roller pair.
（発明が解決しようとする問題点） しかしながら、上記時間ｔを大きくすると撓みは必らず
形成されるが、それだけ複写紙の搬送が停止されること
となり、複写の高速化という観点からは好ましくない。
一方、複写紙検出器の動作特性にはバラツキがあり、こ
れを無視して上記時間ｔを設定しても効果的ではない。(Problems to be Solved by the Invention) However, when the time t is increased, the bending is inevitably formed, but the conveyance of the copy paper is stopped accordingly, which is not preferable from the viewpoint of speeding up the copying. .
On the other hand, there are variations in the operating characteristics of the copy paper detector, and it is not effective to ignore this and set the time t.

わしめることを目的とするものである。The present invention has been made in consideration of the above matters, and it is necessary to form a bend on the upstream side of the conveying means.
Moreover, the time t is set to be the minimum necessary limit even if the variation in the operation of the copy paper detector is sufficiently overcome.
The purpose of the present invention is to speed up copying and to effectively correct the leading edge of copy paper.

照）。In the above description, the upstream detection limit position of the copy paper detector refers to the most upstream position where the copy paper detector detects the copy paper being conveyed and outputs a detection signal, and also the downstream side. Similarly, the detection limit position refers to a position on the most downstream side that outputs a detection signal. For example, a detector K 2 in which a photo interrupter PI and an actuator AC are combined in the embodiment described later will be specifically described (see FIGS. 3 and 4). K indicates the position ML when the actuator AC is turned on when the copy paper is conveyed and the position is UL.
When the position UL is ON, when the position UL is ON, it may be turned ON when the position DL is ON.
L is the downstream detection limit position (for details, refer to the example described later).

ータＡＣが回動し、遮光板Ｓが回動する。K is a copy paper detector (hereinafter referred to as a detector) provided near the upstream side of the conveying means 8. As this detector K, for example, as shown in FIGS. 3 (A) and 3 (B), a photo interrupter PI and an actuator AC are combined, and a copy paper abuts against the actuator AC and presses it to press the photo interrupter PI. A light-shielding plate S provided between the light-emitting side and the light-receiving side is rotated to turn on the photointerrupter PI. R is the actuator AC
And a light-shielding plate S. Then, as the copy paper advances in the direction of arrow F in FIG. 3 (A), the actuator AC rotates and the light shielding plate S rotates.

が停止するように構成されている。Thus, the conveying means 8 is constructed so that its rotation is stopped for at least the time t 1 + t 2 shown below after the detector K detects the copy paper.

(Hereinafter, referred to as position DL, see FIG. 4)
Is a time sufficient to convey the copy paper to form a predetermined bend on the upstream side of the conveying means 8, and the time t 2 is the upstream detection limit position UL (hereinafter, Position UL
That is, the time required for the copy sheet to be conveyed from the position shown in FIG. 4) to the position DL.

位置ＵＬを基準とした場合、上記撓みが必要以上に大き
くなりすぎてしまい、複写の高速化を進める上で大きな
障害となる。The reason why the position DL is used as a reference when setting the time t 1 is as follows. After ON operation of detector K,
There may be a case where a time required to form a predetermined bending is set on the upstream side of the conveying means 8, a case where the position UL is used as a reference, and a case where the position DL is used as a reference. When the position UL is used as a reference, the above-mentioned bending becomes excessively large, which is a major obstacle to speeding up copying.

撓みが形成されるようにしているのである。On the other hand, when the time t 1 is set on the basis of the position DL, the deflection w 1 formed on the upstream side of the conveying means 8
Is a predetermined amount or less. In this case, there is no problem if the deflection w 1 is always a predetermined amount, but there is a problem when it is less than the predetermined amount. The magnitude of this bending amount is caused by the variation in the operating characteristics of the detector K.
As shown in FIG. 3C, when the detector K is turned on at the position UL, a predetermined amount of bending may not be formed. Therefore, in the present invention, the detector K stops the rotation of the conveying means 8 for at least the time t 1 + t 2 after detecting the copy paper, and even when the detector K is turned on at the position UL. The predetermined deflection is formed.

When the print button is pressed, the paper feed roller starts to rotate in the direction indicated by the arrow in FIG. By this rotation, the uppermost copy paper 6'in the paper feed cassette 5 is sent out toward the transport means 8 along the guide member. The detector K is turned on by the time the leading edge of the copy paper 6'contacts the niff position of the transport means 8.

The latent image formed on the surface of the photoconductor 1 is developed by the developing device 3 into a toner image as the photoconductor 1 rotates, and the distance between the frontmost part of the toner image and the transfer device 4 and the conveying means 8 are provided.
When the distance between the front end of the copy paper 6'held in the position and the transfer device 4 matches, the conveying means 8 starts to rotate.
ここで、この検出器ＫがＯＮとなるタイミングは大別し

(C)を参照して説明する。Here, there are roughly three timings when the detector K is turned on, and in each case, FIG. 4 (A), (B),

When the detector K is turned on when C comes to the position DL, the copy paper 6'is closest to the conveying means 8 at the time of the ON, and the conveying means is adjusted in accordance with the exposure timing of the optical system. By the time the roller 8 rotates, the bending w 1 is formed on the upstream side of the conveying means 8 and the leading edge of the copy paper 6'is corrected.

When the detector K is turned on at the position ML intermediate between the position L and the position DL, since the leading end of the copy paper 6'is not closer to the conveying means 8 than in the case described above, the flexure is caused.
A deflection w 2 smaller than w 1 is formed on the upstream side of the conveying means 8,
The leading edge of the copy paper 6'is corrected.

If the detector K is turned on when it comes to L,
t 1 + t 2 is sufficient so that the copy paper 6 ′ is conveyed from the position UL to the position DL and further from the position DL to the conveying means 8 so that a predetermined bending can be formed on the upstream side of the conveying means 8. Since it is time, even in this case, the bending w 3 is formed on the upstream side of the conveying means 8. Note that this deflection w 3 is the above-mentioned deflection w 2
Although it is smaller than the above, it is large enough to correct the leading edge of the copy paper 6 ', and therefore a predetermined leading edge correction is performed.

Compared with this type of copying machine, the time required for copying is shortened, and the speeding up of copying is promoted accordingly. Further, since a predetermined amount or more of deflection can be formed inevitably on the upstream side of the conveying means, the leading end of the copying machine during conveyance can be surely corrected.
