Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] Regarding the improvement of a setting method when setting a stencil sheet in a printer, a stencil sheet set that can improve the troublesomeness in setting the stencil sheet in the printer and the printing position accuracy. 1) In a printer for printing an image to be printed on a stencil sheet for stencil printing set at a printable position, an outer contour line of at least an upper side and one side of the stencil sheet is provided. A mount is formed so that one side end and lower end can be abutted against a reference position of an insertion portion for inserting a stencil sheet of the printer, and one side end and a lower end of the mount are abutted and fixed at the reference position. In this method, the side edges of the stencil sheet are aligned with the vertical lines of the outline and inserted in a manner superimposed on the front surface, and the stencil sheet is transported until the upper side matches the horizontal line of the outline line.

[Industrial applications]

The present invention relates to a printer for producing a stencil sheet for simple stencil printing, and more particularly to an improvement in a method of setting a stencil sheet when the stencil sheet is set in the printer.

[Conventional technology]

Simplified stencil printing machines (Riso Kagaku Kogyo Co., Ltd .: Print Gokko) have become widespread as household simple printing machines.
Widely used for postcard printing and direct mail. Print Gokko uses a flash lamp to illuminate a translucent stencil paper on a manuscript made with ink containing carbon (manuscript by PPC, manuscript by thermal transfer printing, etc.) and irradiates it with carbon to form holes. Printing is performed by applying ink to a perforated stencil sheet.

In recent years, thermal printers of high print quality (for example, about 160 dpi to 400 dpi) have become widespread, and color printing can be performed with high reproducibility and application software by directly making stencils on stencil paper. This method can reduce costs because a flash lamp is not used.

As shown in FIG. 4, a frame 2 coated with an adhesive is affixed to the outer periphery of the surface (the surface in the printing direction) of the stencil sheet 1a. When making a stencil, peel the stencil sheet 1a from the frame 2. After direct plate making, the plate is pasted again, and the frame 2 is set on a simple stencil printer for use in printing. In the figure, the upper and lower concave and convex portions of the stencil sheet 1a and the frame 2 are positioning guides at the time of printing.

When color printing is performed using the stencil sheet 1a, each color ink is applied on the stencil sheet 1a, and the boundaries of the colors are separated by transparent ink so that the color boundaries are not mixed. Was difficult.

However, using a thermal printer, the stencil sheet 1a is decomposed into three colors of Y: yellow, M: red, and C: blue by application software (in some cases, B (black) in addition to Y, M, C). (4 colors)
Create a stencil sheet 1a corresponding to each, and make three (or four)
Color printing can be performed by separately performing plate making.

The stencil sheet 1a is coated with wax on the back surface of a sheet having fine stitches (for example, 200 dpi),
As shown in FIG. 5, the platen 5 of the thermal printer 3a
The stencil sheet 1a is inserted from the medium insertion portion 6a behind the platen, and the knob 50 at the end of the platen 5 is manually rotated to be transferred between the platen 5 and the thermal head 4 and set at a printable position.

When printing is performed from the back side of the stencil sheet 1a by the thermal head 4 without an ink film, the wax melts and drops in the form of dots, thereby making a plate. The thermal element of the thermal head 4 has a resolution of 320 dpi in the case of a 48 dot printer, for example, and can sufficiently cope with the fine holes of the stencil sheet 1a.

In a thermal printer with an automatic setting function,
When the stencil sheet 1a is inserted into the medium insertion portion 6a and an automatic setting button on an operation panel (not shown) is pressed, the platen 5 rotates and stops at a predetermined position, and is automatically set.

[Problems to be solved by the invention]

According to the above-mentioned conventional method, when the stencil sheet is set in the thermal printer, the coefficient of friction of the stencil sheet is small, and when the release paper is attached to a portion of the stencil sheet which is adhered to the frame, the friction coefficient is further reduced. In addition, the stencil sheet is liable to be skewed during the feeding, and it is frequently necessary to correct the inclination after setting. Since the stencil paper is short in length, it cannot be corrected front-to-back and then skewed in the same way as normal printing paper, and test printing cannot be performed. It is difficult to confirm.

Further, since the stencil sheet itself has no stiffness, there is a possibility that after setting, a sheet switch for detecting the presence or absence of a sheet malfunctions to determine that there is no sheet.

Furthermore, since the back surface of the stencil paper is coated with wax, slippage occurs at the time of line feed during printing, and the accumulated line feed dimension tends to be clogged, and the line feed accuracy tends to decrease.

There is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a stencil sheet setting method capable of improving the printing position accuracy and the inconvenience in setting the stencil sheet in a printer.

[Means for solving the problem]

This is a mount formed so as to be able to abut against the reference position. Therefore, one side edge and the lower end of the backing sheet 7 are fixed to the reference position of the printer 3 by abutting on one side edge thereof, and the side of the stencil sheet 1 is aligned with the vertical line of the outline 70 and the front side. Stencil paper 1
Is transported until the upper side coincides with the horizontal line of the outer contour 70.

[Action]

One side edge and the lower end of the backing sheet 7 are fixed to the reference position of the printer 3 by abutting one side edge and the lower end (FIGS. 7A and 7B). Then, the stencil sheet 1 is transported until the upper side of the stencil sheet 1 coincides with the horizontal line of the outline 70 (FIG. 7A).

FIG. 2 shows that the thermal printer 3a and the medium insertion part 6a correspond to the printer 3 and the insertion part 6 of FIG. 1A.

As shown in the plan view of FIG. 2 (a), the backing sheet 7a is formed of a slightly thick paper or a stiff material such as a plastic sheet, and has an outer shape corresponding to the upper side and the left side of the stencil sheet 1a. An outline 70a is printed.

The outer contour line 70a is printed up and down in the case of the vertical set I and the horizontal set II of the stencil sheet 1a. The position of the horizontal line of the outer contour line 70a is such that the upper side coincides when the stencil sheet 1a is set in the printable position in the vertical direction, and the position of the vertical line is the horizontal direction when the left side of the stencil sheet 1a is coincident. The printable position is set.

The convex portion in the horizontal line and the concave portion in the vertical line of the outer contour 70a are positioning guides for setting the stencil sheet 1a and the frame 2 on a simple stencil printing machine, but set the stencil sheet 1a on the thermal printer 3a. Sometimes, it indicates the setting direction (up, down, left, right, front and back) and plays a role in preventing mistakes in the setting direction.

Cutouts 71 and 72 are provided at the lower end of the mount 7a, and the bottoms 73 and 74 of the cutouts 71 and 72 are cut so as to be mountain-folded at the dotted lines (perforations).

Therefore, legs 75, 76 are formed on the lower left and right sides, and legs 75, 76 are formed.
Reference numeral 76 indicates that when the mount 7a is inserted into the insertion portion 6a of the thermal printer 3a, the stability of the mount 7a is maintained, and at the same time, malfunction of a paper switch (not shown) is prevented.

With such a configuration, when setting the stencil sheet 1a in the thermal printer 3a, first, as shown in FIGS. 2 (b) and 2 (a), the left side of the mount 7a is located at the left end of the medium insertion section 6a. Mount 7a as guided
The lower ends of the legs 73 and 74 are inserted into the medium insertion section 6a.

Then, as shown in FIG.
4 is folded in a mountain and engaged with the inside of the rear portion of the medium insertion portion 6a from below to fix the mount 7a.

Next, the back side (the surface coated with wax) of the stencil sheet 1a peeled off from the frame 2 is set to the mount 7a side, and the left side is the outline contour of the mount 7a as shown in FIGS.
FIG. 2 (c) is obtained by rotating the knob 50 of the shaft of the platen 5 in the feeding direction by hand by inserting it along the vertical line of 70a.
As shown in (b), the stencil paper 1 is placed on the horizontal line of the outline 70a.
Send out until the upper side of a matches. The above is a case where the stencil sheet 1a is set in the vertical direction, and FIG. 3 shows a case where the stencil sheet 1a is set in the horizontal direction.

In this way, the outer contour 70a printed on the mount 7a
Is set on the basis of, the setting can be easily performed, and a mistake in the setting direction can be prevented.

〔The invention's effect〕
