Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ink ribbon cartridge in which a cartridge case for storing an ink ribbon is made of paper.

[Conventional technology]

The above-mentioned ink ribbon cartridge has a cartridge case made of paper, which can reduce manufacturing costs.However, in the past, the cartridge case was constructed by folding paperboard into a box shape, and the paperboard was cut. It has been proposed to guide the running of the ink ribbon by sliding one side of the ink ribbon against the end face in the thickness direction of the paperboard (for example, in Japanese Patent Application Laid-Open No.
(See Publication No. 57-49590).

[Problem that the invention attempts to solve]

According to the above-mentioned conventional technology, since the folds of the paperboard are folded back to form a box-shaped cartridge case,
The paper surface tends to swell and become irregular in shape, and the side walls of the cartridge case are formed by folding paperboard into a box shape, so when many ink ribbon cartridges are stacked for transportation or storage, etc. In addition, the folding angle of the folded part of the paperboard tends to change and deform due to the weight of the items stacked above it, resulting in poor shape retention, and the ink ribbon may not function properly due to dimensional defects or deformation of the cartridge case. There are practical problems, such as not being able to run properly.

In addition, since one side of the ink ribbon is brought into sliding contact with the cut end surface of the paperboard in the thickness direction of the paperboard to guide the running of the ink ribbon, the ink ribbon may be bent suddenly during its run, causing the ink ribbon to There are also problems that can easily damage the

The present invention was made in view of the above circumstances, and the purpose is to provide an ink ribbon cartridge that has excellent shape retention and is less likely to damage the ink ribbon by devising the arrangement of paper materials. shall be.

[Means for solving problems]

The characteristic structure of this invention to achieve the above purpose is as follows:
An ink ribbon cartridge in which a cartridge case for storing an ink ribbon is made of paper, and a paper plate-like body is placed between the paper materials forming the upper and lower surfaces of the cartridge case in the ribbon width direction. The side wall portion of the cartridge case is configured by being sandwiched from the direction, and a guide surface for guiding the running of the ink ribbon is formed on the end face of the plate-like body, and this configuration provides the following effects. play.

[Effect]

The side wall portion of the cartridge case is constructed by sandwiching a paper plate from the thickness direction between the paper materials that constitute the upper and lower surfaces in the ribbon width direction of the cartridge case. It is difficult to deform under compression.

Furthermore, since a guide surface for guiding the running of the ink ribbon is formed on the end face of the plate-shaped body arranged with the thickness direction parallel to the width direction of the ribbon, the running of the ink ribbon can be smoothly guided along the longitudinal direction of the ribbon. .

[Effect of idea]

Therefore, the cartridge case is less likely to deform.
It has excellent shape retention and does not easily damage the ink ribbon.
