Description

[Detailed description of the invention] The present invention is an ink ribbon cartridge used in printing devices such as typewriters, teleprinters, office computer terminals, etc., and especially an endless ink ribbon subcartridge that does not require rewinding of the ink ribbon. Regarding.

Endless ink ribbon cartridges, which are used in printing devices such as typewriters, teleprinters, and office computer terminals, have been increasingly used in recent years because they are easy to handle and do not require a rewind mechanism in the printing device. There is.

However, since it was made into a cartridge, the price per print became higher.

Furthermore, since the length of the ink ribbon is limited, the printing life is short and the cartridge must be replaced frequently.

Therefore, a method of refilling only the internal endless ink ribbon began to be adopted.

Recently, printers have been used in which the cartridge is fixed to the printer and can only be replaced with an endless ink ribbon, and refillable endless ink ribbons are also on the market.

However, refilling these cartridges was complicated, and the ribbon could not be refilled completely, or the ribbon could get stuck inside the cartridge during printing.

The present invention is directed to a new refillable endless ink ribbon subcartridge that does not have these drawbacks.

The present invention will be explained with reference to the drawings.

FIG. 1 shows a developed view of the sub-cartridge of the present invention.

On the first opposite side of a rectangular bottom part 2 having a through hole 1 in the center, an inlet/outlet slit part 3, 3' for an ink ribbon and an inlet/outlet side wall part 5, 5' having a glue part 4, 4' are provided. On the second opposite side of the bottom part 2 are wall parts 6, 6', a folded wall part 7,
7', and extruded portions 8, 8' having approximately the same size as the bottom portion 2 are provided in parallel to the second opposite side of the bottom portion.

The extruded parts 8 and 8' have a slit part 9 which can be fitted into each other in a point-symmetrical manner parallel to the second opposite side of the bottom part 2 up to the center.
, 9' are provided.

This developed diagram is punched out on cardboard 12R/m.

First, assemble the assembled box, install the ribbon entrance/exit side wall 5.
, 5', and fold the glued parts 4, 4' inward.

Next, the wall parts 6 and 6' are folded and finally the slit parts 9 and 9' which can be fitted into each other are fitted into each other, and the extruded part 8 is inserted into the bottom part 2.
, 8'.

Coated paper (150 g/d) with black solid printing on the outside of cardboard with PP on the outside and vinyl on the inside is also good, especially if the outside is covered with polyethylene, PP, etc., when the ink ribbon is packed, the ink will leak out. It does not soak into cardboard or coated paper.

Make one parallel cut and two perpendicular cuts in the first opposite side of the bottom portion 2 of the wall portions 6, 6' in a U-shape to form an ear portion 11,
11' further facilitates handling.

FIG. 2 is a perspective view of the sub-cartridge of the present invention (the ink ribbon is omitted) after the exploded view of FIG. 1 is assembled.

Figure 3 is a schematic cross-sectional view of A and A', and Figure 4 is the through hole 1.
It is a schematic sectional view of the state where the extrusion part 8.8' is pushed out with a finger.

When the ribbon is pushed out from the through hole 1 with a finger, the extrusion portions 8° and 8' push out the ribbon inside in parallel, so refilling can be performed completely and reliably.

If the ribbon is not pushed out in parallel, the wall may pull out the ribbon and it may not be possible to refill it.

In addition, the ink ribbon can be pushed out with one hand, and the sub-cartridge can be removed as is, making refilling easy.

Furthermore, there is no need to separately make an extruded portion, which saves time and effort during assembly.

Also, the presence of the ears 11.11' makes it even easier to remove the subcartridge.

Furthermore, by using relatively thin coated paper of around 150 g/d, the ribbon slides smoothly during extrusion and the ribbons in the inlet/outlet slit portions 3, 3' come out, making refilling more complete.

Further, as shown in the schematic cross-sectional view of FIG.
If the ribbon is welded to the spot, it can be inserted into the cartridge without dropping the ribbon, which is especially essential for fixed cartridges.

The entrance/exit part slit parts 3, 3' may be provided not at the center of the entrance/exit side wall part 5, 5', but by omitting the slit parts 4, 4' on one side.

Also, if you make polyethylene or PP thicker or apply an elastic film, the bottom part 2 can be slightly shaped like the ear part 11 without providing the through hole 1.
, 11' and deflect it so that the inner ink ribbon can be pushed out by the extrusion parts 8, 8'.

As described above, the endless ink ribbon sub-cartridge of the present invention can be completely and easily refilled with one hand.
