Claims (1)

[Scope of Claim for Utility Model Registration] (1) A plate mounting table on which a plate is placed, which is arranged on a pedestal at an angle with its lower end facing toward you, and which supports the lower edge of the plate and extends from this lower edge. a pin hole positioning mechanism for positioning the plate at a predetermined pin hole position; a plate centering mechanism for centering the plate in the horizontal direction on the plate placement table; and a plate centering mechanism provided through the plate placement table. The plate material fixing mechanism vacuum-adsorbs the plate material through a plurality of suction holes provided in the plate material, fixes it on the plate material mounting table, and releases it. An automatic vertical registration mark for printing plates that has an automatic pin hole punching mechanism that automatically punches pin holes in the plate, and an automatic registration mark drawing mechanism that automatically draws registration marks on the plate material in response to input from the keyboard on the operation panel. In the drawing and buffer hole punching device, a pair of U's are formed at a predetermined pitch on the lower edge of the plate material while the plate material fixing mechanism remains in the same fixed state as the pin hole punching and register mark drawing of the plate material.
A vertical type automatic registration mark drawing and buffer hole punching device for printing plates, characterized by being equipped with a buffer hole punching mechanism capable of punching character-shaped buffer holes. (2) The automatic vertical register mark drawing and buffer hole punching device for printing plates, in which the buffer holes are punched in a U-shape, as set forth in paragraph 1 of the utility model registration request. (3) In paragraph 1 of the claims for utility model registration,
A vertical registration mark automatic drawing and buffer hole punching device for a printing plate in which the buffer holes are punched in a U-shape with a corner cut. (4) The automatic vertical printer mark drawing and buffer hole punching device for printing plates, in which the buffer holes are punched in a U-shape with a radius, as set forth in paragraph 1 of the utility model registration request.
