IMAGE FORMING DEVICE AND METHOD FOR MANUFACTURING CAN BODY ON WHICH IMAGE IS FORMED
First Claim
1. An image forming device comprising:
- a conveying unit that sequentially conveys can bodies; and
a plurality of image forming mechanisms provided to correspond to the respective can bodies conveyed by the conveying unit, the plurality of image forming mechanisms moving together with the can bodies conveyed by the conveying unit and forming images on the can bodies, whereineach of the image forming mechanisms is provided with a plurality of image forming portions that are capable of simultaneously forming images of mutually different colors onto the can body.

Abstract
A printing device (1) is provided with: a can body conveying mechanism (100) for sequentially conveying can bodies (10); and a can body moving mechanism (200) for moving the can body (10) while forming an image onto the outer circumferential surface of the can body (10) conveyed by the can body conveying mechanism (100). The can body moving mechanism (200) is provided with a rotating member (210) formed in a disc shape and rotating in a clockwise direction in the drawing. The can body moving mechanism (200) is also provided with plural image forming units (220) provided on the rotating member (210) and forming an image onto the outer circumferential surface of the can body (10) while moving the can body (10). The image forming units (220) are each provided with plural ink ejection devices for ejecting ink onto the outer circumferential surface of the can body (10). This provides an image forming device capable of increasing the number of can bodies on each of which an image can be formed per unit time.
