In conventional printing machines, when the rotational movement of the blanket cylinder and the reciprocating movement of the feed pawl are linked, a sprocket provided on the axis of the blanket cylinder and a sprocket on the crankshaft shaft for reciprocating the support base of the feed pawl are linked. Or they were linked together with a timing belt. Therefore, there is a drawback that a timing difference occurs between the rotational movement of the blanket cylinder and the reciprocating movement of the feed pawl due to elongation of the chain band and wear of the sprocket foil.

The rotational motion of the electric motor 1 is transmitted from a sprocket 3 attached to an output shaft 2 of the electric motor 1 to a sprocket 6 of a blanket body 4 and a shaft 5 through a chain 7. The shaft 5 of the blanket body 4 is mounted on the frame 8, and the idle gear group 1 is attached to the drive gear 9 fixed to the end of the shaft 5.
The gear 12 of the crankshaft 11 is engaged with the gear 12 of the crankshaft 11 through the gear 0. This crankshaft 11
A crank arm 13 is fixed to the crank arm 13. A roller 14 provided at the tip of the crank arm 13 is fitted into a cam groove 16 of a cam plate 15, and one revolution of the crankshaft 11 causes the roller 14 to move the cam plate 1.
5 makes one round trip. The cam plate 15 is fixed to a slider 18 inserted so as to reciprocate back and forth through guide bars 17a and 17b horizontally suspended between support plates 16a and 16b protruding from the frame 8. A coil spring 19a is wound around the guide bar 17b at the front of the slider 18, and a coil spring 19b is wound around the guide bar 17a at the rear of the slider 18. When the printing paper P 1 on the platform P is fed between the blanket cylinder 4 and the pressure roller 19, the feed pawl is moved by the gap between the drive gear 9 that controlled the slider 18, the idle gear group 10, and the gear 12 of the crankshaft. Prevents buckling effect. At the top of the slider 18 are feed claws 20, 20', 21, 2.
1' are arranged side by side and arranged front and back, respectively, and are mounted so as to be able to be finely adjusted in the front and back direction. That is, the piece 24 screwed to the slider 18 is slidably inserted into the odd-shaped rod 23 supported on the frame 8 so that it can only rotate, and the collar 25 of this piece 24 is fitted into the groove 26 of the feed pawl base 22. Therefore, when the scale plate/knob 27 of the odd-shaped rod 23 is turned, the piece 24 is rotated, and as the piece 24 moves forward and backward, the feed pawl 22 moves on the slider 18.
moves forward and backward, and the feed claws 20, 20', 21, 2
1' back and forth, it is possible to finely adjust the top and bottom of the printing paper even during operation. In addition, the coil spring 19a, 1
9b may be independently attached to support plates 16a, 16b without being wrapped around guide bars 17a, 17b. Further, the height of the paper trailing edge receiving stage a of the feeding claws 20, 20' is lower than the height of the paper trailing edge receiving stage b of the feeding claws 21, 21'.
