問題があった。In the above conventional technology, as disclosed in Japanese Patent Laid-Open No. 61-178363, in order to change the ejection speed, it is necessary to change the drive speed of not only the ejection roller but also the conveyance roller of the other device main body. There was a problem in that the continuous processing speed could not be increased because the next sheet could not be processed until the sheet being ejected was completely ejected. Moreover, the above-mentioned conventional technology is disclosed in Japanese Patent Application Laid-open No.
As described in Japanese Patent Application No. 1266, the discharging roller is provided with two-path driving means, which makes one mechanism complicated, resulting in an increase in cost.

しなければならず、部品の共用化に問題があり、汎用の
スタック機構を提供するのに問題があった。Furthermore, in the above conventional technology, it is necessary to match the paper transport speed by the ejection roller with the paper transport speed by other transport rollers. The rollers and drive system had to be redesigned, there were problems with sharing parts, and there were problems with providing a universal stacking mechanism.
本発明は、連続処理速度を上げることが可能で汎用的に
使用できるスタック機構を低コストで提供することを目
的とする。An object of the present invention is to provide a stacking mechanism that can increase continuous processing speed and can be used for general purposes at low cost.
上記目的を達成するために、排出ローラの駆動を他の搬
送ローラと独立駆動とし、排出ローラとプレッシャロー
ラの圧接を解除可能としたものである。In order to achieve the above object, the discharge roller is driven independently of the other transport rollers, and the press contact between the discharge roller and the pressure roller can be released.
上記手段により、紙葉が排出ローラの手前の搬送ローラ
をはずれた時、排出ローラとプレッシャローラを圧接さ
せ、本体の搬送ローラとは独立に紙葉の排出動作を行う
ため、紙葉のスタックが完了せずに次の紙葉の処理が可
能であり、またスタック機構の汎用化が可能である。With the above means, when a sheet of paper comes off the conveyance roller in front of the ejection roller, the ejection roller and pressure roller are brought into pressure contact and the sheet is ejected independently of the conveyance roller of the main body, so that the stack of sheets is prevented. It is possible to process the next sheet without completing the process, and the stacking mechanism can be used for general purposes.
以下に本発明の一実施例を第１図により説明する。 An embodiment of the present invention will be described below with reference to FIG.

レノイド９に通電することによりブラケット３を下に引
きプレッシャローラ２と排出ローラ１を圧接させる。The conveyance roller 4 of the main body of the processing apparatus is driven by a motor 11 and conveys the paper sheet 7 in the direction of the discharge roller 1 . The discharge roller 1 is driven by a motor 10, and is provided with a pressure roller 2 facing the discharge roller 1. The pressure roller 2 is supported by a bracket 3, and a solenoid 9 is attached to the bracket 3 via a spring 8. By energizing the solenoid 9, the bracket 3 is pulled down and the pressure roller 2 and the discharge roller 1 are brought into pressure contact. .
排出ローラ１の下流側にはスタッカ６を設け、紙葉７を
スタックする。搬送ローラ４の近傍に紙葉の有無を検出
する用紙センサ１２を設けである。A stacker 6 is provided downstream of the discharge roller 1, and paper sheets 7 are stacked thereon. A paper sensor 12 is provided near the transport roller 4 to detect the presence or absence of paper sheets.
処理装置本体で処理された紙葉７は搬送ローラ４により
排出ローラ１方向に紙葉７を搬送する。The paper sheet 7 processed by the main body of the processing apparatus is conveyed by the conveyance roller 4 in the direction of the discharge roller 1 .
このとき排出ローラ１とプレッシャローラ２は圧接を解

スタッカ６に排出する。At this time, the discharge roller 1 and the pressure roller 2 are released from pressure contact, and the paper sheet 7 is transferred between the pressure roller 2 and the discharge roller 3.
conveyed between the gaps. The paper sensor 12 detects the trailing edge of the paper sheet 7.
After the paper sheet 7 is detected, the paper sheet 7 is conveyed a certain distance, and when the trailing edge of one sheet 7 is removed from the ejection roller 4, the solenoid 9 is turned off.
NL, the discharge roller 3 and the pressure roller 2 are brought into pressure contact, the motor 10 is turned ONL, the discharge roller 1 is immediately moved, and the sheet 7 is discharged to the stacker 6.

送ローラ４は常に紙葉の処理速度のみで動くため、紙葉
７がスタッカ６に完全に排出されなくても次の紙葉の処
理が可能であり連続処理時の処理速度の向上が図れる。According to this embodiment, the ejection speed of the paper sheet 7 can be set to an optimum speed regardless of the conveyance speed of the main body device, and the conveyance roller 4 of the main body device always moves only at the processing speed of the paper sheet. Even if the sheets 7 are not completely discharged to the stacker 6, the next sheet can be processed, and the processing speed during continuous processing can be improved.
また、搬送ローラ４と排出ローラ１の回転速度が無関係
となるため、排出ローラのローラ径は自由に選ぶことが
可能となり、本体の処理速度が異る他の機種へも同一部
品を使用したスタック機構を容易に取り付けることが可
能であり１部品の共用化によるコストダウンが図れる。In addition, since the rotation speeds of the conveyance roller 4 and the discharge roller 1 are unrelated, the roller diameter of the discharge roller can be freely selected, allowing stacking using the same parts to be applied to other models with different processing speeds. The mechanism can be easily installed, and costs can be reduced by sharing one part.
本発明の他の実施例を第２図により説明する。Another embodiment of the present invention will be described with reference to FIG.

出ローラ１により紙葉７をスタッカ６に排出する。The difference from Fig. 1 is that the discharge roller 1 is driven by an electromagnetic clutch 1.
This is done by the motor 11 which drives the conveyance roller 4 via the motor 3. By turning on the electromagnetic clutch 13, the discharge roller 1 is driven by the motor 11. As in the case of FIG. 1, after the paper sensor 12 detects the rear end of the paper sheet 7, it is conveyed a certain distance, and the solenoid 9 is brought into pressure contact with the ONL ejection roller 1 and the pressure roller 2, and the electromagnetic clutch 13 is turned on. The paper sheet 7 is discharged to the stacker 6.
この実施例においても第１図の実施例と同様の効果を得

ラケット３には復帰バネ１７が取りつけられている。FIG. 3 shows another embodiment. The difference from the embodiment shown in FIGS. 1 and 2 is the means for pressing the discharge roller 1 and the pressure roller 2 together. Gear 1 is attached to the shaft end of discharge roller 1.
4 is attached using a bracket 16 and a gear 15 to form an oval planetary gear. That is, the gear 15 can rotate together with the bracket 16 while meshing around the gear 14. An arm portion 16α protrudes from the bracket 16 and is engaged with the bracket 3 of the pressure roller 2, and when the bracket 16 is lowered, the pressure roller 2 is brought into pressure contact with the discharge roller 1. A return spring 17 is attached to the bracket 3.

圧接は解除される。Similar to the embodiments shown in FIGS. 1 and 2, when the rear end of the sheet 7 leaves the conveyance roller 4, the discharge roller 1 is driven. (The ejection roller is driven by the method shown in the embodiment shown in FIG. 1 or FIG. 2.) When the ejection roller 1 is rotated in the direction of ejecting the sheet 7 (in the direction of arrow A), the bracket 16 also moves in the direction of arrow A. The rotating force acts to push down the bracket 3 of the pressure roller 2, bringing the pressure roller 2 into pressure contact with the ejection roller and ejecting the paper sheet 7 into the stack 6. When the rotation of the discharge roller 1 is stopped, the pressure contact of the pressure roller 2 is released by the return spring 17.
本実施例によれば第１図、第２図の実施例と同様の効果
が得ることができる。さらに、ソレノイドの電気部品が
不要となるのでコストダウンを図ることができる。According to this embodiment, the same effects as the embodiments shown in FIGS. 1 and 2 can be obtained. Furthermore, since electrical parts such as solenoids are not required, costs can be reduced.
本発明によれば、紙葉の排出動作を装置本体の搬送とは
独立にできるので、連続処理速度の向上を図れる。According to the present invention, since the ejection operation of paper sheets can be made independent of the conveyance of the apparatus main body, it is possible to improve the continuous processing speed.
また、排出の紙葉速度は装置本体の搬送速度に無関係と
なるので、搬送速度の異る機種にも同一のスタック機構
が適用出来１部品の共用化によるコストダウンが図れる
。Furthermore, since the speed of sheet discharge is independent of the conveyance speed of the main body of the apparatus, the same stacking mechanism can be applied to models with different conveyance speeds, and costs can be reduced by sharing one part.
