FIG. 1 is a sectional view showing an embodiment of the present invention. In the figure, a plurality of rotatable paper ejection rollers 3 are loosely fitted into a paper ejection frame 2 provided on the side of a main body frame 1 of a copying machine, etc., on a roller shaft 4 fixed to the paper ejection frame 2. The paper ejection roller 3 is driven by a paper ejection roller 5 which is rotatable on a shaft fixed to the paper ejection frame 2 . These paper discharging rollers 3, paper discharging rollers 5, etc. form a discharging means. Further, a paper ejection gear 6 is fixedly installed on the shaft of the paper ejection roller 5 as a second gear, and the main body frame 1
Drive can be transmitted by a drive gear 8 that receives driving force from a chain 9 via an idle gear 7 as a first gear rotatably attached to the drive gear 8 .

を解放され駆動停止されることになる。 A long hole 22 is formed in the paper ejection frame 2, and the elongated hole 22 is fitted into the support shaft 10 fixed on the main body frame 1 so that it can move freely up and down. is able to swing up and down and rotate freely. Further, a notch 11 is formed in the main body frame 1, and the roller shaft 4 of the paper ejection frame 2 is engaged with the notch 11 at a predetermined position, so that the paper ejection frame 2 is in a predetermined installed state. It has become possible to take In this state, the driving force from the idle gear 7 is transmitted to the paper discharge roller 5. In this state, the paper ejection frame 2 brings the ejection gear 6 into contact with the idle gear 7 due to its own weight, and the paper ejection roller 3 contacts the paper ejection roller 5 due to its own weight to transmit drive. will be done. Therefore, the driving torque when discharging the sheet is very light, and the paper discharging roller shaft 4 does not come off from the notch 11 of the main body frame 1. For example, when an operator's finger or the like is caught between the paper ejection roller 5 and the paper ejection frame 2, an abnormal external load is applied to the paper ejection roller 5, and the elongated hole portion 2 of the paper ejection frame 2 2 , the roller shaft 4 of the paper ejection frame 2 is moved upward from the notch 11 of the main body frame 1 in the direction of the arrow shown in the figure, and the paper ejection gear 6 is moved upward from the idle gear 7. The drive will be released and the drive will be stopped.
さらに、本体フレーム１に形成された切欠き形
状及び配置は図示以外の任意のもので可能である
ことはもちろんである。 Furthermore, it goes without saying that the shape and arrangement of the notch formed in the main body frame 1 can be any shape and arrangement other than those shown in the drawings.
以上説明したように、本発明の構成によると、
シート排出部の駆動は簡単に駆動解除ができるの
で、例えば操作中指等をはさんだ場合でも駆動解
除ができ安全性が良いものである。 As explained above, according to the configuration of the present invention,
Since the driving of the sheet ejecting section can be easily released, the driving can be canceled even if, for example, the operator's middle finger or the like is caught, and safety is good.
