Abstract

PURPOSE:To reduce the number of parts required so as to allow the cost to be reduced by allowing only a delivery means to rotate either normally or reversely through both No.1 and No.2 one way clutches. CONSTITUTION:With a drive motor rotated normally, a drive shaft 18 is rotated through a worm gear 25. This causes both a paper feed output gear 19 and No.2 delivery output gear 22 to rotate to the direction X1 as shown by an arrow head through No.1 one way rotary clutch C1 and C2 permitting both a paper feed input gear 17 and a separation gear 15 to rotate to the direction X2 as shown by an arrow head, also permitting a separation roller 7 to rotate to the direction 'b' as shown by an arrow head. This causes each of paper feed pulleys 3 and 4 to rotate to the same direction through each of shafts 3a and 4a permitting a paper feed belt 6 to rotate to the direction 'a' as shown by an arrow head, also permitting a drive roller 10 to rotate to the direction 'c' as shown by an arrow head. Besides, when a sensor S is activated allowing the motor 24 to rotate reversely, the worm gear 25 is rotated to the direction Y as shown by an arrow head allowing only No.1 delivery output gear 21 to rotate to the direction 'y1' as shown by an arrow head through No.2 one way rotary clutch C2 continuing delivering through a shaft 10a of a delivery means B'.

On the other hand, the rotation of the second feed output gear 22 rotates one feed idle gear 23 in the direction of arrow x6, and rotates the feed input gear 20 in the direction of arrow x7 via the other feed idle gear 23. As the feed input gear 20 rotates, the drive roller 10 rotates in the direction of arrow C via the shaft 10a. Here, when the feed idle gear 23 is configured with a spur gear, only one feed idle gear 23 is required. Furthermore, when the separation idle gear 16 is configured to mesh with the second feed output gear 22, the paper feed output gear 19 and the first one-way rotary clutch C1ζ disposed thereon become unnecessary.

In this way, by the rotation in the first rotation direction accompanying the forward rotation of the drive motor 24 of the drive source C', both the paper feeding means A and the feeding means B are rotationally driven, and the paper P (see FIG. reference)
is fed from the paper feed tray 2.

By the way, at the end of the shaft 4a of the second paper feed gear 13, there is a rotary plate 27 with a large number of small holes, and a light emitting element S1 and a light receiving element S2 arranged facing each other with the rotary plate 27 in between. The leading edge of the sheet P fed as described above is connected to the feeding means B.
At the time when the sheet is fed, or when the sheet feeding means A is rotationally driven, the drive control circuit 28 is turned on by the output of the sheet feeding sensor S, and the drive motor 24 is reversely rotated.

This reversal of the drive motor 24 causes the worm 25 to move to the sixth position.
In the figure, it rotates in the direction of arrow Y, and the drive shaft 18 rotates in the direction of arrow y. As the drive shaft 18 rotates in the direction of the arrow y, only the first feeding output gear 21 rotates in the direction of the arrow y1 via the second one-way rotation clutch C2, as shown in FIG. Here, the paper feed output gear 19 and the second
As shown in FIG.
The transmission of rotation from 8 is cut off, and paper feeding means A
drive is stopped. On the other hand, the rotation of the feeding means B1, that is, the drive roller 10 is caused by the rotation of the feeding input gear 20 in the direction of the arrow y2, which is the same direction as the arrow x7, with the rotation of the first feeding output gear 21. , continues via axis 10a. Therefore, the supplied paper P is continuously fed by the feeding means B and fed into the main body of the copying machine or the like.

In addition, when only this feeding means B is rotationally driven,
In other words, when the drive source C' is rotated in the second rotation direction due to the reverse rotation of the drive motor 24, the friction between the paper P, the paper feed belt 6, and the separation roller 7 causes the paper feed belt 6 and the separation roller 7 to separate. Even if the roller 7 follows the rotation, the drive shaft 18
Since the transmission of rotation between the paper feed output gear 19 and the second feed output gear 22 is cut off, no problem occurs.
