Abstract: PROBLEM TO BE SOLVED: To enhance printing properties by inhibiting print defects to be caused by the wear of a doctor blade and thereby improving the ease of operation. SOLUTION: When sliding a doctor blade 2 to scrape a surplus ink to be supplied to the peripheral face 1a of a plate cylinder 1, the pressure of a pressurizing means 3 which presses the doctor blade 2 to the plate cylinder 1, is controlled using a pressure control means 4 to change the pressure for pressing the doctor blade 2 to the plate cylinder 1. The pressurizing means 3 as an air cylinder 6. The pressure control means 4 comprises a contact time detection device 7 which detects time when the doctor blade 2 is kept in contact with the plate cylinder 1 of the doctor blade 2, a conversion part 8 which converts the contact time to a first electric signal to decide a pressure and converts the first electric signal to a second electric signal, and an electricity and air conversion device 9 which drives an air cylinder 6 by the second electric signal. The pressure control means 4 may have a contact position detection device which detects a position where the doctor blade 2 comes into contact with the plate cylinder 1 instead of the contact time detection device 7 and converts the described contact position to the first electric signal at the conversion part 8.

Abstract: PURPOSE:To prevent rubbing of undried ink by a method wherein the end part of a printing sheet is grasped by sheet nipping means at the tips of a plurality of arms of a sheet passing-on part to convey the sheet, and the surface, on the opposite side to printing side, of the printing sheet is brought into a state to point in a direction extending along the arcuate recessed part of a guide member. CONSTITUTION:By rotating a sheet passing-on part 24 in a direction shown by an arrow mark, a printing sheet is conveyed to a subsequent partial printing part 8 and nipped by means of a sheet chuck 13a of a pressure drum 13, and approximately simultaneously to above, the printing sheet is released from sheet nipping claws 30, 30, and 30 of the sheet passing-on part 24. Air 38 and 38... discharged through air discharge holes 22, 22,... of a support shaft 19 are collided with a printing surface 37 of a printing sheet 6. The printing sheet 6 is advanced as it is pressed against a guide surface 36 of a guide member 35. Air collided with the printing surface 37 of the printing sheet 6 flows in two ways along the printing surface 37 of the printing sheet 6 formed in an arcuate recessed surface formed along the guide surface 36 of the guide member 35, and flows out from the two ends on both sides of the guide member 35. This constitution provides a printing surface 37 drying of ink on which is enough for next printing.

Abstract: PROBLEM TO BE SOLVED: To properly eject ink by securing evenness of an object of ejection, and to prevent a stain on the backside of the object of the ejection, in terms of a platen plate for supporting the object of the ejection of a liquid drop ejected from each nozzle of an undersurface of a liquid ejection head.
SOLUTION: This platen plate 1 supports recording paper 51 which serves as the object of the ejection of an ink drop ejected from each of the nozzles 23 of the undersurface of the ink ejection head 20. The platen plate has a plurality of ribs 2-6 which are erected from its bottom surface part 1b, which are elongated in the carrying direction of the recording paper 51, and which are arranged at predetermined intervals in the width direction of the recording paper 51. The platen plate is formed so as to specify a distance between the recording paper 51 and an ink ejection surface 22 by supporting the backside of the recording paper 51 by top surfaces of the ribs outside an area whereto the ink drop ejected from each of the nozzles 23 adheres in a covering manner. The platen plate is formed so that the top surfaces of the ribs can have a height which prevents contact with the back side of the recording paper 51, within the range whereto the ink drop ejected from each of the nozzles 23 adheres in the covering manner. Otherwise, the platen plate is formed in such a manner as to lack the rib itself.
