とができる。(Effects of the Invention) As described above, in the present invention, the flat printing plate 16 is supported slidably in the vertical direction via the printing plate holder 19 at the front end of the pressing arm 5 whose rear end is supported. In the pressing device for a surface printing plate, a pressing force adjustment mechanism 17 for adjusting the pressing force of the flat printing plate 16 is provided between the front end of the pressing arm 5 and the printing plate holder 19, and a pressing force adjustment mechanism 17 for adjusting the pressing force of the flat printing plate 16; Since a slope follower mechanism 18 such as a restoring rubber that can be bent and deformed according to the slope of the flat printing plate 16, the platen 47
When stamping the upper printing material A, as shown in FIGS. 4 to 6, as the pressing arm 5 swings downward, the flat printing plate 16 moves downward via the printing plate holder 19. It can be slid and stamped onto the printing material A. At this time, as shown in FIGS. 4 and 5, the pressing force applied to the stamp surface of the flat printing plate 16 can be set in advance by the pressing force adjustment mechanism 17 according to the thickness of the printing material A. When the set pressing force is exceeded, this pressing force is released, so the flat printing plate 1
The pressing force and stamping time of No. 6 can be kept constant at all times. In addition, as shown in FIG. 6, since the printing material A on the platen 47 is bent and deformed according to the inclined surface etc. by the inclined surface following mechanism 18 such as a restoring rubber, it has the ability to follow the inclined surface etc. Even if the conditions of the printing substrate A are different, the quality of the seal impression is always constant and the stamp can be stably stamped.

Inside the press guide shaft 44, there is an inner escape 21 with appropriately shaped sliding pieces 35 protruding rearward on both sides.
The escape tension spring 22 is supported on the front side of the west escape 21 so as to be slidable in the vertical direction.
Since each sliding piece 35 on both sides of the inner escape 21 is fixed to the pressing shaft 43 via the spring pressing body 23 with the pressing adjustment screw 45, as shown in FIGS. 4 and 5. As shown in FIG.
5, and as the front end side of the pressing arm 5 swings downward around the support part at the rear end, the pressing shaft 43 is adjusted at both sides of the inner and side escapes 21. The sliding piece 35 presses against the upper protrusion from the upper end against the upward force of the escape tension spring 22 to press the inner escape 21 and the outer escape 20 downward, and the pressing shaft 43 presses the inner escape 21 and the outer escape 20 downward. When the upper protrusion of each sliding piece 35 is exceeded, the inner escape 21
and the outer escape 20 is the escape tension spring 2
It slides upward while coming into pressure contact with the pressing shaft 43 due to the elastic force of No. 2. Therefore, the pressing force applied to the stamp surface of the flat printing plate 16 can be set in advance by the pressing force adjusting screw 45 of the pressing force adjusting mechanism 17 according to the thickness of the printing medium A, and both sides of the inner escape 21 of the pressing force adjusting mechanism 17 can be set in advance. Coupled with the fact that each sliding piece 35 of the section is released when a preset pressing force is exceeded, the pressing force and stamping time of the flat printing plate 16 can be kept constant at all times.
