PROBLEM TO BE SOLVED: To solve a problem of increased sliding nose, which is caused by the increase of the number of the open edge part of respective opening in a hexagonal pattern being simultaneously contactingly caught by the tip and corners of the free end part of a scraping blade at the pressing of the free end part of the scraping blade against the inner peripheral surface of a plate cylinder at the rotation of the plate cylinder at printing to its rotational direction and by the increase of the generating places of frictional resistance and. SOLUTION: In the plate cylinder device 35 in a stencil printing equipment equipped with the scraping blade 13 arranging contactingly with the inner peripheral surface 3 of a plate cylinder within the plate cylinder 7, under the condition that the respective opening area in a large number of openings 4 in the plate cylinder 7 and the total amount of ink passing through the opening part of the plate cylinder 7 are kept unchangeable, the opening parts 5 of a large number of openings are arranged so as to decrease the number of simultaneous contact of the scraping blade with the respective opening edge parts 4a of a large number of the openings 4.
