Abstract

PURPOSE:To provide a stencil printing device which neither oozes out ink through a form plate at the time of processing nor contaminates a hand nor changes the ink in quality even if an unused stencil printing original plate is kept for a long time. CONSTITUTION:A stencil printing device is constituted of heat-sensitive stencil paper 1, a screening film 2, a heating element 4 stuck to the screening film 2, an impregnated body 7 which is impregnated with ink, a frame body 6 which is arranged so as to surround the impregnated body 7, an ink-impermeable back-up film 9 which is stuck to the frame body 6 and an impressing electric power source applying voltage to the heating element 4. When the voltage is applied to the heating element 4 by the impressing electric power source, the heating element 4 is heated by the voltage applied to the heating element 4 by the impressing electric power source, the screening film 2 is burnt out, the ink infiltrated into the impregnated body 7 is oozed out of a perforated part of the heat-sensitive stencil paper 1 after passing through a burn-out part of the screening film 2 and the ink is transferred to printing paper.

If the thickness is too small, the heat-sensitive stencil sheet 1 will enter the inside of the frame 6 during plate making and will not come into contact with the thermal head. On the contrary, if the thickness is too large, the impregnated body 7 is pressed by the pressing force of the thermal head.
Even if is compressed, it does not become less than the thickness of the frame body 6. Therefore, when the stencil printing plate 20 is conveyed during plate making, the frame 6
Since it becomes difficult to press a transporting means such as a roller on only the stencil, variations in the thickness of the impregnated body 7 cause unevenness in the transporting pitch of the stencil printing plate 20, or the stencil printing plate 20 is skewed and transported. Problems such as occur.

At the time of plate making, the thermal head 21 is brought into contact with the stencil printing base plate 20 by a predetermined pressing force. At this time, between the heat-sensitive stencil base paper 1 and the impregnated body 7 impregnated with ink. Since the shielding film 2 is arranged, even if the thermoplastic film 31 of the heat-sensitive stencil sheet 1 is perforated, the ink does not ooze out from the perforated portion.

After the plate making, the stencil printing plate 20 is applied with the power source 2
A voltage is applied to the heating element 4 through the application electrode 10 by 3. The heating element 4 generates heat due to the voltage applied by the applied power source 23, and the shielding film 2 is burned off.

The stencil printing plate 20 thus prepared is mounted on the stamp member 40 as shown in FIG. The stamp member 40 includes a handle portion 41, a cushion layer 42, and an adhesive layer 43. The stencil printing master plate 20 is mounted by adhering the backup film 9 side of the stencil printing master plate 20 to the adhesive layer 43 of the stamp member 40.

As is clear from the above description, since the stencil printing apparatus of the present invention has the shielding film between the heat-sensitive stencil sheet and the impregnated body impregnated with the ink, the stencil sheet is printed at the time of plate making. No more ink bleeding. In addition, since the shielding film can be burnt off without touching with a hand at the time of marking, the marking can be performed without dirtying the hand. Furthermore, since the unused stencil printing plate does not come into contact with the air, the quality of the ink does not change.
