Problems solved by technology

In this way, if information is received from an external input device to form an image, although the convenience is improved, since the sending side and the receiving side are located at separate positions, there is a problem of reducing the confidentiality of the image forming data.

Embodiment Construction

[0018] A first embodiment of the present invention will be described.

[0019] Figure 1 shows a stencil printing apparatus. In this figure, the stencil printing device 1 has a printing part 2, a plate making part 3, a paper feeding part 4, a printing plate part 5, a paper discharging part 6 and an image reading part 7, and an external input device 8 is connected to the stencil printing device 1 .

[0020] The printing unit 2 disposed approximately at the center of the apparatus main body 9 has a printing cylinder 10 and a press roller 11 . The printing cylinder 10 has a porous support plate having a perforated portion and a non-perforated portion formed with a plurality of perforations on the outer peripheral surface. The printing cylinder 10 is rotationally driven by a printing cylinder driving motor 12 which will be described later. A multi-layer mesh screen made of resin or metal mesh is wound on the opening part of the porous support plate, and a free opening and closin...

Abstract

The present invention discloses a porous printing device and a porous printing system. To prevent the secret leakage when the printing is executed according to the information sending from the exterior input mechanism, a mechanism which reels the printing roller of the key plate relative to the free engaging external circumference surface of the printing device body only at the preset position is arranged, and a secret mode setting device which sets the mode of the porous printing device to the secret mode that protects the content of the image data is also arranged, and at the situation that the secret mode is set the printing roller is arranged at a position except for the roller position when the printing action is finished.

Description

technical field [0001] The invention relates to a stencil printing device connected with an external input device and a stencil printing system. Background technique [0002] As we all know, the existing simple printing method is digital thermal stencil printing. In the stencil printing device that performs this digital thermal stencil printing, when the next printing is performed after the printing is completed and the original is replaced, the printing plate device is operated by pressing the platen start key, and the used master plate is peeled off from the printing cylinder, and then The plate making device operates to rewind the structure of the master plate after plate making on the printing cylinder. This is because if the used master plate is peeled off from the printing cylinder immediately after printing, and the surface of the printing cylinder is placed in a state exposed to the air when a new plate-making master plate is wound until the next printing, if the I...
