PROBLEM TO BE SOLVED: To adopt a paper feeder of a chuck system as a cover supply device, and to easily correct an inclination of a cover and an inclination of printing to the carrying-out direction even in operation.SOLUTION: This cover supply device has a pair of left-right chuck mechanisms composed of a chuck claw 2a pivoted on a side surface of a rotating circular arc-shaped drum 1a and a cam 4a for rocking its chuck claw 2a on a surface of the drum from the circular arc-shaped edge of the drum and in the direction for retreating from its surface, and carries out one cover H1 taken out by a sucker 13 from a cover stacking shelf 12 by gripping and extracting by the drum 1a and the chuck claw 2a of the pair of chuck mechanisms, and is provided with an operation mechanism 8 for changing a boundary position of a crest and a trough of the cam 4a for rocking the chuck claw 1a of one chuck mechanism of the pair of chuck mechanisms, and corrects an inclination of the cover and an inclination of the printing by making the gripping timing different by the pair of chuck mechanisms by operation of a handle 8c of its operation mechanism 8. |
