Problems solved by technology

When the recording drum is rotating at high speed, due to the weight of the punching unit, it will be difficult to rotate the recording drum with high accuracy unless the weight balance of the entire recording drum is adjusted very accurately
When the punching unit is customized, weight balance adjustment must be performed on the recording drum again, so its disadvantage is that it is not easy to customize the punching unit

Abstract

A punch unit includes punch blocks supported by an arm through support plates. The arm has, arranged thereon, a motor for rotating a drive rod (105), a detector for detecting rotation angles of the drive rod, and a sensor for detecting a forward end of a recording material. The punch unit is movable by a moving mechanism including support members arranged at opposite ends of the arm, slide shafts and ball screws connected to the support members, and a pulse motor for driving the ball screws through a synchronous belt and synchronous pulleys.

Description

technical field [0001] The present invention relates to an image recording apparatus for recording an image by emitting a light beam to a recording material mounted on a recording drum. Background technique [0002] When printing with four color inks, such as yellow (Y), purple (M), cyan (C), and black (B) inks, the positioning holes for the printing machine used to position the printing plate and the printing plate Between recorded images, the same positional relationship must be maintained for each of the YMCK colors. As used in this specification, the term "pilot hole for a printing press" includes a pilot hole for placing a printing plate on the plate cylinder of a printing press, as well as a punched hole, such as a pilot hole, for placing a printing plate Place on the punch to create another punched hole in the printed board. [0003] In the method proposed in USP6213020 (hereinafter referred to as "the first method"), before the recording material is attached to the...
