Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stencil plate making apparatus for heating and perforating a master plate with a heating element such as a thermal head, and a master storage unit mounted on the stencil plate making apparatus.

[0002]

2. Description of the Related Art Digital thermal stencil printing has been known as a simpler printing method. In this method, a thermal head in which fine heating elements are arranged in a row is brought into contact with a heat-sensitive stencil master (hereinafter referred to as a master), and the master is conveyed while energizing the heating elements in a pulsed manner. After selectively perforating the master by heating, ink is transmitted through the perforated portion and the ink is transferred to printing paper to form a printed image.

As a master used in this digital thermal stencil printing, as shown by reference numeral 2 in FIG. 1 of JP-A-6-32041, a master wound in a roll shape is already known. This master roll is stored in the master storage section of the stencil printing machine. Conventionally, the new master roll is installed by the operator taking the new master roll out of the packaging box, removing the locking member such as tape that holds the master tip, and then checking the front and back of the master roll. The master roll is set in the storage section, the tip of the master roll is pulled out from the master storage section, and the tip is clamped by the plate making means of the stencil printing machine. The method is completed by manually cutting the cut master and manually removing the cut tip of the master from inside the stencil printing machine.

However, in the above-described work of mounting the master roll, the work of mounting and dismounting the master roll in and from the master storage portion is very troublesome, and wrinkles occur in the master unless the mounting work is performed carefully. However, since there is a problem that printing defects occur, it is impossible for a general operator, and there is a problem that a skilled and dedicated operator must perform the operation.

The master used as the master roll has a laminated structure in which an ink-permeable porous support and a thermoplastic resin film are bonded together. As the porous support, general Washi paper or synthetic fiber, or a mixture of Washi paper and synthetic fiber is used, but the thickness and length of the fiber used, and the thickness and density are uneven. Therefore, the ink permeability varies. That is, uniform permeation of ink is hindered when a large number of fiber-like portions are scattered in the perforated portion of the film, or when thick fibers cross the perforated portion of the film. Further, an adhesive is used to bond the thermoplastic resin film and the porous support, but due to the unevenness of the adhesive, even permeation of the ink through the film perforated part where the adhesive is applied in a large amount is possible. Is hindered.
If the areas with poor ink permeability are scattered in this way, even if heat-punching plate making corresponding to a predetermined original image is made on the thermoplastic resin film, white areas of the printed image will appear on the areas with poor ink permeability described above. There is a problem in that a dropout easily occurs, and a so-called printed image with poor solid fill is formed.

[0006]

Problems to be Solved by the Invention JP-A-63-3029
No. 5 discloses that a master roll is stored inside a master storage means having a master guide portion coated with a release agent in order to prevent perforation failure due to melting and sticking of the master to the heating element of the thermal head. Techniques for doing so are disclosed. However, when using this technique to attach and detach the master roll, the operator must manually pinch the tip of the master pulled out from the master roll into the master guide section. There is a risk that the master will be wrinkled.

Further, in Japanese Patent Laid-Open No. 87094/1985, instead of Japanese paper, a porous support in which fibers of uniform thickness are regularly arranged is used, and this is bonded to a thermoplastic resin film. The technology used as a master is disclosed. However, in this master, even if a new master just made into a plate is wound around the plate cylinder, the ink supplied from the inside of the plate cylinder does not reach the thermoplastic resin film unless it sufficiently penetrates into the porous support, Even if printing is started, there is a problem that a proper print image cannot be obtained on the first 1 to 3 printing sheets. In addition, the used master used for printing is discarded after being peeled from the plate cylinder and stored in a predetermined plate discharge portion. At this time, the used master contains a large amount of ink in its porous support. Since it is discarded as it is, there is a problem that the running cost of ink increases. In order to solve this problem, it has been attempted to print using a master having a thin porous support, or using a master substantially consisting of a thermoplastic resin film without using the porous support. However, while the thickness of the conventional laminated structure master is 40 to 50 μm, the thickness is 2 to 8 μm for the master substantially made of the thermoplastic resin film.
And very thin, the strength (waist) of the master will be greatly reduced. Therefore, when a new master is set in the stencil printing machine, static electricity causes the master to stick to a hand or a guide plate, which causes wrinkles on the master and prevents normal setting. If paper powder or dust adheres to the surface of the film, there is also a problem that reliable heating and perforation cannot be performed during plate making.

The present invention solves the above-mentioned problems, and a stencil plate making apparatus and a stencil plate making apparatus which can be easily and surely attached and detached by a general operator when the master roll is attached and detached to and from the master container. Even when using a master storage unit and a master consisting essentially of a thermoplastic resin film, the generation of wrinkles on the master is prevented,
It is an object of the present invention to provide a stencil plate making apparatus capable of easily and surely setting a master.
