Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink ribbon disposal bag, and more particularly to an ink ribbon disposal bag suitable for use when replacing a used ink ribbon with an unused ink ribbon.

In typewriters, embossing type printing devices, etc., an ink ribbon wound around a pair of pulleys or rollers is usually suspended so that it passes between the type and the paper, causing the paper and type to collide to print. It is supposed to be done.

The same applies to printing devices in which the type mentioned above is formed by a large number of pin-shaped flying bodies at the bottom of the tank. , parts of the ink ribbon containing more ink are sequentially supplied to the printing position.

When the ink ribbon wound around one pulley or roller runs out, the rotation of the pulley or roller is reversed to reverse the feeding direction of the ink ribbon.

In order to eliminate the need for such a mechanism for reversing the feeding of the ink ribbon, thereby lowering the cost and reducing failures, there have been conventionally provided ink ribbons using an endless ink ribbon.

FIG. 1 is a plan view of a printing device using this ink ribbon, in which 1 is an ink ribbon, 2 is a ribbon package containing an unused ink ribbon 1 for replacement, and 3 is a plan view of a printing device using this ink ribbon.
a to 3d are pin-shaped ribbon guides that guide the running of the ink ribbon 1; 4a is a drive roller; 4b is a driven roller rotatably held by a swinging arm 5; 6 is a swingable roller on the ribbon path side. 7 is a type held unit that accommodates a type belt 8 suspended between pulleys 7a and 7b, and 9 is an ink ribbon stretched along the type belt running surface of the type belt unit 7. 10 is an ink ribbon container.

When the driven roller 4b is in a position where it is pressed against the drive roller 4a, it cooperates with the drive roller 4a to draw the ink ribbon 1 into the container 10 and simultaneously fold it sequentially.

Further, the ribbon separator 9 is formed with a window (through hole) having a width slightly larger than the width of the type, and paper (not shown) is guided to the surface opposite to the surface facing the ink ribbon 1. It has become so.

Further, a hammer mechanism (not shown) is provided on the back side of the paper, and the hammer mechanism pushes the paper against the ink ribbon through the window of the ribbon separator 9 and collides the paper and the ink ribbon with the type belt 8. It is designed to print automatically.

Now, when replacing the ink ribbon in such a printing device, after taking out the used ink ribbon 1 from the container 10 and discarding it, attach the ribbon package 2 to a predetermined position, and remove the used ink ribbon from the ribbon package 2. Pull out the ink ribbon by a predetermined length (approximately equal to the ink ribbon path length), move the brake arm 6 and swing arm 5 in the direction of arrow A, open the ink ribbon path, and at the same time remove the cover of the container 10 (not shown). ).

After passing the endless open ink ribbon across the opened ink ribbon path and the container 10, the arms 5 and 6 are moved in the direction opposite to arrow A, and the cover of the container is closed. Attach.

Note that the figures show a state in which the cover is always removed for convenience of explanation.

Thereafter, by rotating only the drive roller 4a or rotating the drive roller 4a together with the printing operation, the ink ribbon 1 is drawn into the container 10 and folded as shown in the figure.

The present invention enables the user to easily and quickly take out the used ink ribbon from the storage container 10 and dispose of it without getting his or her hands dirty when replacing the ink ribbon, and the ink ribbon can be easily folded and is not bulky. The purpose is to provide ribbon disposal bags.

This purpose is achieved in the present invention by an ink ribbon consisting of a rectangular cylindrical guide member that can be deformed into a flat shape, and a bag made of a flexible oil-resistant or water-resistant material and having a continuous opening in the guide member. This is achieved by a disposal bag, and one embodiment thereof will be described in detail below with reference to the drawings.

FIG. 2 is a perspective view of an ink ribbon disposal bag (hereinafter simply referred to as a bag) according to the present invention, and FIG. 3 is a sectional view of the guide 30 shown in FIG. 2.

In FIG. 2, reference numeral 30 is a rectangular cylindrical guide made of a member that can be deformed into a flat shape such as cardboard, and the front portion 31 is cut diagonally; 35 is a joint containing adhesive (shaded portion); 40
The bag is made of a resin such as vinyl chloride and is thin and flexible, and is resistant to ink, i.e., oil-resistant or water-resistant. 41 is a hole for discharging the air inside the bag 40.

The width (outer width) of the guide 30 is equal to or slightly smaller than the width (inner width) of the container 10 shown in FIG.

This allows the side walls 32a, 32b of the guide 30 to slide into contact with the inner wall of the container 10, so that the ink ribbon 1 can be scooped up completely.

Moreover, since the front part 31 of the guide 30 is cut diagonally, visual inspection becomes easy, and the ink ribbon 1 enters the guide 30 without resistance, making it extremely easy to operate.

Furthermore, since the bag 40 is made of oil-resistant or oil-resistant material, even if the ink solvent, such as oil or water, flows out from the ink ribbon housed in the bag 40 after passing through the guide 30, it will penetrate into the bag 40. Therefore, there is no need to get your hands dirty, and it is hygienic.

Needless to say, since this bag is inexpensive, it is discarded while still containing the used ink ribbon.

Furthermore, in order to make it easy to use, when attaching one ink ribbon to an unused replacement ink ribbon, the guide portion 30 changes from the shape shown in FIG. 3A to the shape shown in FIG. The shape can be deformed by applying an arrow-like force,
At the same time, since the bag 40 is flexible, the bag can be folded according to the size of the guide 30 to save bulk.

This folding is easy because the bag 40 has air vent holes 41 at its ends.

As described above, according to the present invention, it is possible to provide a compact ink ribbon disposal bag that allows ink ribbons to be replaced hygienically, easily, and quickly.
