Claims

[Scope of utility model registration request]

A large number of mandrels are arranged horizontally at equal intervals near the periphery of the vertically rotating disk, a cylindrical can body is fitted onto the mandrels, and the can body is rotated in a predetermined direction by the rotation of the vertically rotating disk. A device that performs overprinting on the outer circumferential surface of a cylindrical can body by conveying the can through a route and rolling the transfer cylinder, whose outer circumferential surface is coated with ink, into contact with the outer circumferential surface of the body of the can being conveyed. Each of the mandrels has a mandrel shaft rotatably supported by the vertical rotating disk and connected to a drive device, and further includes a tapered portion formed on an outer peripheral surface of the mandrel shaft; A reverse taper that matches the tapered portion is formed on the inner circumferential surface, and the mandrel shaft shaft is connected to the tapered portion of the mandrel shaft through a guide member, and is bound into an integral cylindrical body by a spring member so that the diameter can be expanded and contracted. What is claimed is: 1. A device for overlapping printing on the outer peripheral surface of a cylindrical can body body, characterized by comprising a can body holding mechanism consisting of a plurality of holding members fitted so as to be slidable only in one direction.
