Description

[Detailed Description of the Invention] The present invention relates to a printer device for a manual label printing and pasting machine that performs multicolor printing. When the characters printed on the label include different types of characters such as product model name, sales date, price, etc., it is easier to see if the characters are printed in different colors for each type. For this color-separated printing, there are two ways to perform color-separate printing, using multiple printers and using different color ink pads for each printer, and one method that uses multiple ink pads on one printer. Although there is a method in which the tape is divided into individual parts and each part is impregnated with a different color ink, the latter method is generally used from the viewpoint of product cost and the weight of the entire pasting machine. A conventional general example of a printer for a label printing and pasting machine using the latter method has a structure as shown in FIGS. 1 and 2. FIG. 1 is a side view of only the printer unit, and FIG. 2 is a front view of only the printer and roll-type ink pad. The printing device 1 operates for printing and pasting (the operating mechanism is not shown).
The printer 11 is fixed integrally with the swing lever 2 which swings by the printing operation, and when the printing operation is performed, the swing lever 2 swings counterclockwise and the printer 11 is lowered downward. There is a printing ring 4 on the top of the outer frame 3 of the printing device 1.
A support shaft 6 that rotatably supports a rotary base 5 on which a rotary base 5 is mounted and rotates is fixedly clamped, and a print 71 to be printed of the print 7 engraved on the print wheel 4 is shown at the bottom.
A trapezoidal shaft 8 is held horizontally on the lowermost surface of the printing wheel 4. A plurality of rotating bases 5 are provided, each having a number corresponding to the number of printing wheels 4, and a rotary operating plate 9 for rotating the base is fixed to each unit. The printing wheel 4 is mounted in parallel between the rotating base 5 and the trapezoidal shaft 8. That is, by rotating the rotary operation plate 9, the printing wheel 4 is rotated. Reference numeral 10 denotes an ink pad device, which includes cylindrical ink pads 11 and 12 each impregnated with ink of a different color, a disc-shaped partition plate 13 separating them, and an ink pad 1.
1 and 12, and a shaft 1 that passes through the ink pads 11 and 12, the partition plate 13, and the side plate 14.
5, and the shaft 15 is rotatably held by an ink pad arm 16. The ink patch arm 16 is rotatably attached to a pin 19 provided on a stay 18 fixed to a side plate 17 of the main body, and a clockwise rotational force is applied by a torsion spring 20. That is, in the normal position where the printer is in the upper position as shown in the figure, the ink pad is rotated clockwise by the torsion spring 20 to print 71.
When the printing device 1 is lowered by the operation of the pasting machine, the ink pad is rotated counterclockwise against the torsion spring 20, and the ink pad is applied to the print 71 while printing. It comes into contact with the side surface (the right side surface in the figure) of the outer frame 3. 21 is a sticking roller attached to the tip of the main body side plate 17.

When the printer 1 configured as described above is lowered, ink is applied to the prints by the first ink pad 11 and the second ink pad 12 is applied to the prints 71 to 74. This will result in printing 75 and 76.

However, when the label printing and pasting machine is operated, the swing lever 2 shakes, so the printing device 1 attached to the tip of the swing lever 2 shakes considerably, causing a correlation mark between the printing wheel 4 and the ink pads 11 and 12. It often happens that two colors are applied to the inside of the different color prints, that is, the prints 74 or 75 (or both) in FIG. 2, due to misalignment.

As mentioned above, this invention is a roll-type ink with multiple colors.
In those using ink and pad devices with ink pads installed in parallel, the ink pad partition plate has a large diameter, and its outer edge is always between the printing wheels (between adjacent printing wheels to which different colored inks are applied). Even if the printing device shakes as described above, the relationship between the print on the printing wheel and the ink patch of the color to be inked on it will always be accurate. The present invention will now be described with reference to the drawings.

FIG. 3 is a front view (same drawing as FIG. 2) showing an embodiment of the printer device according to the present invention, in which the same reference numerals as in FIGS. 1 and 2 indicate the same parts; The partition plate 13' is always connected to the printing wheels 74, 75.
It is said to be of such a size that it is inlaid in the lower part of the space. Because this is done, ink pads 11 and 12 are printed not only when the printing device 1 is in the normal position above the ink pads as shown in FIG. When the printing device 1 is lowered and the ink pad device 10 moves to the side of the printing device 1,
The width of the outer frame 3 of the printing device 1 is selected so that the outer edge of the partition plate 13' rotates while being fitted between the printing wheels 74 and 75. That is, this state is shown in FIG.

As described above, the partition plate 13' of the ink pad is fitted between the predetermined printing wheels of the printing device 1, and the engaged state is maintained regardless of the position of the printing device 1. Even if the ink pads 11 and 12 of different colors apply ink, the correlation between the respective prints is maintained accurately even if the ink pads 11 and 12 of different colors are applied.

[Brief explanation of the drawing]

Figure 1 is a side view of only the printer unit of an example of a conventional manual label printing and pasting machine that uses a single printer to perform multi-color printing using roll-type ink pads, and Figure 2 shows the printer and the printer. FIG. 3 is a front view of an embodiment of the printer device according to the present invention (a drawing similar to FIG. 2), and FIG. 4 is a front view of the printer device according to the present invention. The side view shows a state in which the printer is lowered and the ink pad device is moved to the side. 1... Printing device, 3... Printing device outer frame, 4... Printing wheel, 7...
