Description of the Related Art As shown in FIG. 5, a wide and long ink ribbon 1b used in a printer is entirely wound around a ribbon supply spool 2 when it is new and the opposite end is a ribbon take-up spool. 4 is locked. The ink ribbon 1b wound around the pair of spools 2 and 4 in this manner is housed in a state of being rotatably engaged with the ink ribbon holder 1.

As shown in FIG. 5, the pair of spools 2 and 4 have cylindrical body portions 2a and 4a formed of a wide ink ribbon 1b and ink ribbons at both ends of the body portions 2a and 4a. 1b for guiding 1b, and a cylindrical engagement portion 2c for engaging the ink ribbon holder 1 rotatably on the outer side of the collar portions 2b, 4b and concentrically with the body portions 2a, 4a, 4c.

As shown in FIG. 5, the ink ribbon holder 1 includes a cylindrical cartridge 3 for accommodating a ribbon supply spool 2, a cylindrical cartridge 5 for accommodating a ribbon take-up spool 4, and cylindrical cartridges 3, 5. The cartridges 3 and 5 are arranged in parallel at a predetermined interval and integrally molded with inner connecting rods 6 and 7, which are thin connecting rods connecting the front portions and the rear portions of the cartridges 3 and 5, and are formed into a substantially spectacle shape.

A square opening 1a is formed on the upper surface of the ink ribbon holder 1, and the ink ribbon 1b can be exposed through the opening 1a.

At both ends of the cylindrical cartridges 3 and 5, there are provided circular through holes 3a and 5a having a diameter such that the engaging portions 2c and 4c of the spools 2 and 4 can be loosely fitted. There is.

The ink ribbon holder 1 having such a structure and the pair of spools 2 and 4 are provided at both ends of the ribbon supply spool 2 and the ribbon take-up spool 4 in the cylindrical cartridges 3 and 5. Engagement part 2c,
4c is loosely fitted in the eyeglass-shaped through holes 3a, 5a and is rotatably supported.

Ink ribbon 1b constructed as described above
The ink ribbon holder 1 wound with is attached to a printer as it is for use. That is, when the ink ribbon holder 1 is mounted in the printer, the engaging portions 2 of the spools 2 and 4 are
c and 4c are adapted to be engaged with a drive shaft provided in the printer to be rotationally driven.

The ink ribbon holder 1 accommodating the ink ribbon 1b as described above is packed at the time of factory shipment as shown in FIG.

First, the entire ink ribbon holder 1 is put in a polyethylene bag 8 and the mouth 8a of the bag 8 is closed. on the other hand,
Put a large number of photographic paper 9 in a polyethylene bag 10
The zero mouth 10a is sealed. Then, a bag 8 containing the ink ribbon holder 1 is covered with a U-shaped spacer 11 by bending both ends 11a and 11b of a paper sheet in accordance with the size of the ink ribbon holder 1.

Next, the bag 10 containing the photographic printing paper 9 is placed on the spacer 11. Finally, the whole is stored in a cardboard individual carton 12 and the lid 1 of the individual carton 12 is closed.
Close 2a. The upper portion of the ink ribbon holder 1 thus packed is protected by the spacer 11, and the lower portion and both side surfaces thereof are protected by the individual carton 12.

[0012]

However, the above-described packaging of the ink ribbon holder has the following problems.

Since the wrapping of the photographic paper 9 having a considerable weight is put on the ink ribbon holder 1 housed in the individual packaging carton 12 via the spacer 11, the individual packaging carton 12 is printed. When an impact such as a drop is received from the outside with 9 being up, the weight of the printing paper 9 is impacted from above the spacer 11 at the moment of landing.

Since the spacer 11 is made of thin paper, the central portion of the photographic printing paper 9 is recessed by the above-mentioned impact load, and as a result, the cylindrical cartridges 3 and 5 and the inner connecting rods 6 and 7 shown in FIG. Near the boundary (P1, P in FIG. 5)
There is a problem that a large bending stress is applied to 2) and it is damaged.

As a measure for preventing such damage, when the ink ribbon holder 1 is packed in the individual carton 12, another member is applied under the inner connecting rods 6 and 7 for reinforcement. Although it can be considered, there is a problem in that the number of parts is increased, the packaging cost is increased, and the packaging work time is increased to deteriorate the mass productivity. Further, if the strength of the inner connecting rods 6 and 7 is increased, it is necessary to change the design of the ink ribbon holder 1 and the cost is increased.

Therefore, the present invention is intended to provide a spacer for preventing damage of an ink ribbon holder for solving the above-mentioned problems, and is inexpensive without increasing the number of parts, easy to pack, and easy to package. However, there is a problem in the structure of the spacer, which has a high ability to protect the ink ribbon holder.

[0017]

In order to solve the above problems, a carton for an ink ribbon unit according to the present invention is
An ink ribbon unit including a pair of spools around which a predetermined wide ink ribbon is wound, and an ink ribbon holder provided with an inner connecting rod that connects a cylindrical cartridge for accommodating the pair of spools at predetermined intervals. A spacer formed by folding both ends so as to surround the ink ribbon unit to form a U-shape, and a carton for packaging the ink ribbon unit with the spacer attached. That is, the column portion having substantially the same height as the height of the both ends bent at the substantially central end position is formed of the same member.

With the structure of the spacer, the center of the inner connecting rod of the ink ribbon holder is supported from below by the column in the individual carton.
Even if a stress is applied to the inner connecting rod from above when it is dropped, the inner connecting rod is prevented from being damaged.

Since the column portion can be formed by a simple bending process of the base paper of the spacer without increasing the number of parts, the protection ability of the ink ribbon holder can be improved without increasing the cost. .
