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 Indicates a stencil printing device. 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 clos...

Abstract

The invention discloses a stencil printing device and a stencil printing system. In order to prevent leakage of confidentiality when printing based on information sent from an external input device, it is provided with a mechanism for winding the printing cylinder of the master plate on the outer peripheral surface of the main body of the printing device only at a predetermined position and freely detachable from the main body of the printing device. A confidential mode setting device that sets the mode of the stencil printing apparatus to a confidential mode for protecting the content of the image data, and when the confidential mode is set, the printing cylinder is positioned at the position other than the drum position.

Description

technical field [0001] The present invention relates to a technique for preventing leakage of secrets in a stencil printing device connected to an external input device. 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...
