DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the field of stencil printing, and in particular to a heat-sensitive stencil sheet and an apparatus for improving the convenience of loading the heat-sensitive stencil sheet into a plate-making apparatus such as a heat-sensitive stencil plate making machine. Related to the combination of.

[Prior Art] In heat-sensitive stencil printing, in which an extremely thin thin film of a synthetic resin is perforated with a group of fine holes that give a desired image as a whole, and ink is extruded through these holes to perform printing. As suggested in Japanese Patent Application No. 50-30474 (Japanese Patent Publication No. 54-23601), which is the application of the same applicant as the applicant, the "one-minute value" by the spread meter is 32 or less. When using an ink with a relatively low fluidity, apply the ink in a layer having a considerable thickness on the perforated heat-sensitive stencil sheet, press the heat-sensitive stencil sheet onto the printing paper, and press it from above the ink layer. By applying the pressure, it is possible to continuously print a large number of prints without replenishing the ink for each print.

As a heat-sensitive stencil sheet assembly suitable for such a printing method, an annular frame body made of cardboard, and a frame body that overlaps one surface of the frame body and extends over the entire circumference along the peripheral edge of the frame body. A heat-sensitive stencil sheet set having a fixed heat-sensitive stencil sheet and an ink impermeable ink holding sheet which is fixed to the frame body at a part of the peripheral edge of the frame body which overlaps with the other surface of the frame body. A three-dimensional object has been proposed in Japanese Utility Model Application No. 50-51306 (No. 51-132007), which was filed by the same applicant as the applicant of the present application, and is used for stencil printing using such a heat-sensitive stencil sheet assembly. A suitable simple stencil printing machine was proposed in Japanese Patent Application No. 51-114235 (No. 57-15814), which was filed by the same applicant as the applicant of the present application. Widely used in printing.

By the way, the perforation of the heat-sensitive stencil sheet is a thin film made of a synthetic resin on an image formed by an ink or other image forming means that contains a large amount of an infrared absorbing substance such as carbon that originally absorbs infrared rays and can generate heat. Was pressed so as to come into contact with each other, and a ray rich in infrared rays was irradiated through the thin film, and the thin film of the synthetic resin was melted by the heat generated in the image area by the light, and the word processor in recent years, in particular, With the development of Japanese word processors, the development and practical use of a multi-point matrix print head for printing characters with a set of fine dots
The heat-sensitive stencil sheet can be directly punched by a heat-generating multi-point matrix printing head, and the same person as the applicant of the present invention has been able to do this in Japanese Patent Application No. 52-98961 (JP-A-54-331).
No. 17).

When directly punching a heat-sensitive stencil sheet with a printing device such as a typewriter or a word processor equipped with a heat-generating print head, a heat-sensitive stencil sheet that is considerably thinner and softer than ordinary paper is used. It is rather difficult to load around the platen commonly used in the printer of the present invention. Also, of course, the above-mentioned actual application Sho-50-5
No. 1306 (No. 51-132007), which is an annular frame made of cardboard and overlaps with one surface of the frame and extends along the entire periphery of the frame. A heat-sensitive stencil sheet assembly such as having a heat-sensitive stencil sheet fixed to the frame body,
Normally, it cannot be loaded in a printing device such as a typewriter or a word processor. In view of this point, the same person as the applicant of the present invention is the same as the applicants in Japanese Patent Application No. 1-117434 and Japanese Patent Application No. 1-117435, as shown in FIGS. 1 is combined with an annular frame body 2 made of a relatively thin paper material fixed to its periphery and having a slippery surface, and the frame body 2 has an annular frame body 3 made of cardboard at its slippery surface. A heat-sensitive stencil sheet 1 is formed by adhering to a layer 5 of an adhesive substance on one surface so that the heat-sensitive stencil sheet can be peeled and reattached.
When directly drilling a hole, this is used together with the frame 2 and the frame 3
Proposed a more temporary separation. In addition, in the figure 4
Is an ink impermeable sheet which is impermeable to ink.

[Problems to be Solved by the Invention] However, even when a frame body made of a relatively thin paper is provided on the periphery of the heat-sensitive stencil sheet as described above, it is loaded in a plate-making apparatus such as a heat-sensitive sheet-making machine. Is not necessarily easy.
A plate making apparatus such as a heat-sensitive stencil plate making machine generally holds one side of a rectangular heat-sensitive stencil sheet so that the front edge of the cardboard in the feeding direction is attached along one generatrix of a cylindrical drum of the plate making apparatus. In many cases, it is fixed to a device, and in order to attach a thin and soft front end of a sheet to a plate making device, such as a heat-sensitive stencil sheet, a sturdy strip having a considerable width dimension along the front edge of the sheet is used. Convenient to exist.

In view of the above-mentioned circumstances regarding loading the heat-sensitive stencil sheet into a plate making apparatus such as a heat-sensitive stencil plate making machine, the present invention simplifies the convenience of loading the heat-sensitive stencil sheet into a plate-making apparatus such as a heat-sensitive stencil plate making machine. The purpose is to provide a combination of effective and effective devices.

[Means for Solving the Problems] According to the present invention, the above-mentioned problems include a heat-sensitive stencil sheet and a rectangular annular frame body which is fixed to the periphery of the heat-sensitive stencil sheet and has a smooth surface. A heat-sensitive stencil sheet with a frame, a rectangular sheet-shaped substrate, and a sheet-shaped substrate which is selectively exposed to a strip-shaped region along one side of a rectangle on one surface of the sheet-shaped substrate. A layer of a non-drying weak adhesive, and a sheet-like covering material that covers the non-drying weak adhesive layer so as to be easily exposed, and by removing the sheet-like covering material, An edge forming device which is releasably adhered to the sliding surface of one side of the rectangular annular frame of said framed heat sensitive stencil sheet in layers.

[Advantage of the Invention] As described above, the rectangular sheet-shaped substrate and the sheet-shaped substrate are selectively exposed to the strip-shaped region along one side of the rectangle on one surface of the sheet-shaped substrate. If there is an edge forming device having a layer of a non-drying weak adhesive and a sheet-like covering material that covers the non-drying weak adhesive layer so that it can be easily exposed, the edge forming device is made of a relatively thin paper material and has a smoothness. When loading the heat-sensitive stencil sheet with a frame having a rectangular annular frame having a surface into a plate making apparatus, the sheet-like covering material was removed from the above-mentioned edge forming apparatus, and the sheet-like substrate was exposed to the non-drying material. By attaching to the side of the frame located at the front end of the heat sensitive stencil sheet in the feeding direction to the plate making device at the weak adhesive layer portion,
The heat-sensitive stencil sheet immediately becomes a heat-sensitive stencil sheet at the front end in the feeding direction when the plate-making device is loaded, with the above-mentioned strip-shaped reinforcement by the sheet-like substrate.

Then, the heat-sensitive stencil sheet is perforated as required in the plate making apparatus, and the heat-sensitive stencil sheet is mounted on the frame body made of the above cardboard or other apparatus for printing work. When the temporary reinforcement material is removed from the heat-sensitive stencil sheet by releasing the non-drying weak adhesive layer from the peelable adhesive, the heat-sensitive stencil sheet can be removed from the temporary reinforcement device provided by the above sheet-shaped substrate. Easily released.

[Embodiment] FIG. 3 and FIG. 4 attached herewith are a plan view and a side view showing an embodiment of an edge forming device for constructing the combination of the present invention as described above. In these figures, 10 is a rectangular sheet-like substrate, which is preferably made of a strong but thin, but relatively resilient paper material. Note that, in FIG. 4, the thickness of the sheet-shaped substrate 10 is shown in a greatly enlarged form as compared with the rectangular shape dimension shown in FIG. 3 for convenience of illustration. One surface of the sheet-shaped substrate 10, that is, the fourth surface
A layer 12 of non-drying weak adhesive is applied to the surface to the right of the figure in the illustrated embodiment over its entire surface. The non-drying weak adhesive may be any known material used in so-called loose "seals" and the like. In FIG. 4, this layer is overlapped with a sheet-like base material and a straight line showing the contours and boundaries of the sheet materials 14 and 16 described below, and the layer thickness is particularly indicated. Absent.

On the surface of the sheet-shaped substrate 10 on which the non-drying weak adhesive layer 12 is applied, rectangular sheet materials 14 and 16 made of the same sheet material as the sheet-shaped substrate 10 in the illustrated embodiment are provided. The non-drying weak adhesive layer 12 is bonded by viscous adhesion. Of these, in particular, the sheet material 16 is such that the surface in contact with the non-drying weak adhesive layer 12 is a smooth surface, so that the sheet material 16 is easily peeled off from the non-drying weak adhesive layer 12 and is bonded again on it. Has become
It acts as a sheet-shaped covering material for the non-drying weak adhesive layer 12.

5 and 6 are heat-sensitive stencil plates provided with a frame body 2 made of thin paper material as shown in FIG. 2 using the edge forming device shown in FIGS. 3 and 4. FIG. 3 is a plan view and a side view showing a state in which one end portion of the base paper 1 is reinforced. In this example, the frame body 2 is provided with an ear portion 2a at one end portion for facilitating the alignment when loading the printer, and the other end portion corresponding thereto is provided. A notch 2b having the same contour as the contour of the ear 2a is provided. As better understood in the comparison of FIGS. 5 and 6, the edge forming device shown in FIGS. 3 and 4 has been removed from the sheet 16 and subsequently exposed. At the portion of the non-drying weak adhesive layer 12, the heat sensitive stencil sheet 1 and the frame 2 are attached along one edge of the combined body. In FIG. 6 also, the sheet-shaped base material 10 and the sheet material 14
Similarly, in FIG. 4, the thickness of the frame 2 is greatly enlarged in comparison with its plane contour size, and the frame body 2 is also shown in its thickness greatly enlarged in comparison with its plane contour size for convenience of illustration. Has been done.

Thus, the heat-sensitive stencil sheet 1 is provided with a sheet-like base material at one end thereof, which is provided with the frame body 2 made of thin paper, and which is still inconvenient to load into a plate-making apparatus such as a heat-sensitive base paper plate-making machine only by the frame body 2.
A strong strip-shaped sheet material composed of a combination of the sheet 10 and the sheet 14 is temporarily attached to a part of the sheet-shaped substrate 10 by a non-drying weak adhesive layer, so that one end thereof can be conveniently loaded into the plate making device. Is prepared in a significantly improved state. It should be noted that the sheet-shaped substrate 10 or the sheet 14 or a part of the surface of both may be provided with arrows, scales or the like to assist the positioning required when loading the heat-sensitive stencil sheet into the plate-making apparatus.

Further, after the predetermined perforation work on the heat-sensitive stencil sheet is completed, the combination of the sheet-shaped substrate 10 and the sheet 14 is easily peeled off from the heat-sensitive stencil sheet by the non-drying weak adhesive layer 12, and the heat-sensitive stencil sheet is After that, it is loaded into the printing device and ink is applied,
It may be subjected to printing. On the other hand, in the combination of the sheet-shaped substrate 10 and the sheet 14 removed from the heat-sensitive stencil sheet, the sheet 16 may be re-pushed to the exposed portion of the non-drying weak adhesive layer 12, and this The edge forming device can be stored until next use.

[Advantages of the Invention] Thus, as described above, the rectangular sheet-shaped substrate 10 and the sheet-shaped substrate are selectively exposed on one surface of the sheet-shaped substrate in a strip-shaped region along one side of the rectangle. An edge forming device having a non-drying weak adhesive layer 12 applied to a sheet and a sheet-like covering material 16 for easily exposing the non-drying weak adhesive layer is made of a relatively thin paper material and is smooth. When used in combination with a heat-sensitive stencil sheet with a frame having a rectangular annular frame having a flexible surface, the frame is a relatively thin paper material with a frame but is still soft as a whole. The belt-like reinforcement is immediately given to one end of the heat-sensitive stencil sheet which is inconvenient to load, and the convenience of loading the heat-sensitive stencil sheet into the plate making apparatus is significantly improved.
