As shown in the figure, a friction pad type in which the upper roller 1 that rotates in the sheet conveying direction and the separation pad 2 are in contact with each other (XI)
Upper roller 1 rotates in the sheet conveyance direction as shown in Figure 7.
A friction roller type in which a separation roller 3 that stops or reverses is brought into contact with the belt.As shown in Figure S, it consists of a pair of upper and lower endless belts 4 and 5 that are in contact with each other. A friction belt type in which the belt 5 is stopped or rotated in the opposite direction, using narrow belts to overlap the upper and lower belts (Fig. 11) as shown in Figs. 9 and 10. There is a belt paper waist separation method in which one belt 4 is rotated in the sheet conveying direction and the other belt 5 is stopped or rotated in the opposite direction from a plurality of upper and lower endless belts 4.5.
しかし、何れも紙が分離されて搬送部材から出てくるま

先端のエツジ部が分離部材と当り、先端が折れたり破れ
たりして(第12図)ニップ部から先へは進まないで紙
が送れないなどの欠点があった。特に傷んだ紙などは顕
著で、j!!擦分離方式の最大の弱点であった。However, by the time the paper is separated and comes out of the conveying member, the separating member has stopped or rotated in the opposite direction, so the edge of the leading edge of the paper hits the separating member, resulting in the leading edge being bent or torn. (Fig. 12) There were drawbacks such as the paper could not be fed beyond the nip portion. This is especially noticeable on damaged paper, etc. ! This was the biggest weakness of the friction separation method.
そのため第13図、第14図のような方式が提案されて
いる。第16図の場合は低摩擦部材をニップ部ぎりぎり

クリミッタ−との関係が非常に難しく、トルクリミッタ
−の値を実験的に決めて本そのトルクリミッタ−を作る
のに苦労を要し又経時的にみてトルクリミッターの値が
当初の値のまま保つのは非常に困難であった。For this reason, methods such as those shown in FIGS. 13 and 14 have been proposed. In the case of FIG. 16, the low-friction member is brought close to the edge of the nip to prevent the leading edge of the paper from hitting the separation member, but it is quite difficult to attach the low-friction member to the very edge of the nip. If the low-friction member is placed a little in front of the nip, it is of no use, and problems such as the tip breaking may still occur. Also, if a person slightly gets into the nip, the mechanical part of the separating member will be damaged, making it easy to feed multiple sheets, which is not necessarily a good idea. The relationship between μ (coefficient of friction) between the separating member and the paper, the separating pressure, and the torque limiter is very difficult, and it takes a lot of effort to experimentally determine the value of the torque limiter and create the torque limiter. Moreover, it has been extremely difficult to maintain the torque limiter value at its original value over time.
第16図はその方式の紙が送られる行程図である。呼び
出しローラ9から送られた紙は分離部の上ローラ1、分
離ローラ3に送り込まれる。FIG. 16 is a diagram showing the process by which paper is fed in this method. The paper sent from the calling roller 9 is sent to the upper roller 1 and separation roller 3 of the separating section.

われる。紙が3枚以上の場合も同様で3枚→2枚→1枚
となるだけで紙が1枚に々るまで逆転するだけである。The calling roller 9 is sent to a place where it seems to be caught by the upper roller 1 and the separating roller 3 (FIG. 16μ)), and is lifted upward by a solenoid or the like (not shown). In Fig. 16 (Bl. in Fig. 16), the fed paper is always transmitted with the opposite rotation to the separation roller 3 in Fig. 5, so in Fig. 5 (At), the paper is separated. The roller 3 is rotated by the upper roller 1, and in the case of (middle) μm>μ2
〉Due to the relationship between μ3, the resistance of the μ3 portion is small, and the paper P1 is sent by the upper roller 1, and the paper P2 is transported by the separation roller 3 to Pl.
The paper is fed in the opposite direction until one sheet of paper is left, resulting in the state of (,k). (When the paper enters the state of Al again, it becomes the state of Bl, and then reverses again and returns to the state of Buddha. This is repeated. If there are three or more sheets of paper, the same goes for 3 sheets → 2 sheets → 1 sheet) All you have to do is reverse the paper until it becomes one sheet.

is a driven hub, and 26 is a torque limiter. In addition, in the figures, unexplained members correspond to numbers in the 10s of the members in FIG.

の表面状態も大きく作用していた。In all of the above-mentioned conventional separations, most of the separation is determined at a wedge portion where curvatures or straight lines of rollers, belts and rollers, belts and belts, etc. touch, or at a point a little further from the wedge portion. For this reason, the conveyance and separation of the upper paper, which is fed, and the lower paper, which is not fed, and the IIEK, are determined by unstable conveying force or blocking force. In other words, it is extremely difficult to pass just one sheet through the narrow wedge portion as shown in FIG.

モータMOとクラッチct2が制御手段を構成する。Next, when a start command is issued, a solenoid (not shown) is activated, and the calling roller 109 is lowered to send the document P to the separating section 132 (Fig. 4(A)). It is held between rollers 101 and 103 and sent forward (Fig. 4 (Bl). At this time, the separation roller 10
5 is the upper roller 10 in the A direction, that is, the same direction as the upper roller 101.
It is sent forward with a rotational force of 1. At this time, clutch cL+
is on, and clutch c12 is off. One to several sheets are sent and nine sheets are detected by the sensor 130 (@Figure 4 (C)
)). When detected, the separation roller 103 is rotated in the direction B, that is, in the opposite direction to that of the upper roller 101, by turning on the clutch cL2 (FIG. 4 CD)'). As a result, the sandwiched sheets of paper are pushed back in order, starting with the original at the bottom, leaving only one original (see Figure 5). One roasted manuscript is μm〉
Since the relationship is μ2 and the sheet is set to be fed in the rotational direction of the upper roller 101, only one sheet is sent forward. If the sensor 130 is off and the trailing edge of the document passes), the paper feed command is issued continuously, as shown in (G) 1 in Figure 4. (
The state shown in figure A) is reached, the calling roller 109 comes down again, and the separating roller 103 stops rotating in reverse (clutch cL2
), rotates in the same direction as the upper roller 101,
The document is sent in again and the operation at (Bl-(g))t is performed. The sensor 130 and the clutch ct2 (electromagnetic clutch) are connected via a control circuit, and this control circuit, the motor MO, and the clutch ct2 constitute a control means.
