Abstract

PURPOSE:To enable a surface of a platen roller and a surface of a printing head to be easily certainly cleaned by a method wherein a cleaning tool to which a damp material and a dry cloth material are jointly provided is made to travel by the same operation as in printing. CONSTITUTION:A damp material 1b having a damp layer wetted by alcohol or the like and a dry cloth material 1C having a dry cloth layer composed of a gauze or the like are alternately arranged on a cleaning sheet 1. A protective sheet 1a which covers each of them and is stuck, in a peeling off free manner, onto cleaning sheet 1 is peeled off to be removed, and the surface of the stupe material 1b and the dry cloth material 1c are exposed. When a surface of a platen roller is cleaned, the cleaning sheet 1 is so set that the surface of the platen roller is brought into contact with the surfaces of the damp material 1b and the dry cloth material 1c to be made travel in the same way as the operation when paper is printed. Then, after dissolving ink or the like adhered onto the surface of the platen roller in solvents such as alcohol or the like preliminarily moistening the material, the solvents come to be wiped off by making the dry cloth material 1c pass.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning tool for cleaning paper dust and the like adhering to a platen surface in a printing apparatus that prints on paper using a print head and a platen.

[Conventional technology]

FIG. 6 is a perspective view showing a printing section of a conventional printing device;
In the figure, 2 is a platen roller, 3 is a head, and 4 is a sheet of paper that is held between the platen roller 2 and the head 3 and run for printing.

Next, the operation will be explained. The paper 4 is pressed by the platen 2 between the head 3 and the platen roller 2.
The paper is rapidly fed in the direction of arrow A by the rotational force of the paper, and during this time the head 3 prints on the paper.

[Problem to be solved by the invention]

Although the conventional printing apparatus is constructed as described above, it has a drawback that paper dust and the like adhere to the platen roller surface and the print head surface. In particular, when printing a large number of sheets of paper, the amount of deposits increases, and in the past, it was common practice to perform troublesome maintenance such as periodically wiping the platen roller surface and print head surface with a gauze cloth soaked in alcohol or the like. It took.

Further, there were other problems such as the need to store alcohol and the like for use in the printing device in advance.

This invention was made to solve the above-mentioned problems.The platen roller surface and print head surface can be cleaned using the same operations as normal printing. The purpose is to obtain cleaning tools that do not need to be stored.

[Means to solve the problem]

The cleaning tool according to the present invention is equipped with poultice materials and dry cloth materials that appear alternately in the traveling direction of the platen.

[Effect]

In this invention, the ink and the like adhering to the platen surface are first dissolved with a poultice material to make it easier to clean, and then the dry cloth material that appears is used to completely wipe it off.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a cleaning sheet used in the present invention, and FIG. 2 is a perspective view showing the cleaning sheet installed in a printing device. In the figure, 1 is a cleaning sheet, and 1b and 1e are arranged alternately on the upper surface of the cleaning sheet. A poultice material has a poultice layer soaked with alcohol or the like, and a dry cloth material has a dry cloth layer made of gauze or absorbent cotton. , 1a is a protective sheet 1 which covers the poultice material 1b and the dry cloth material 1e and is removably attached to the cleaning sheet 1.

When using the cleaning sheet 1 constructed in this manner, the protective sheet 1m is first peeled off and removed to expose the surfaces of the poultice material 1b and the dry cloth material 1c. Then, as shown in Figure 2, in the same way as printing on paper,
When cleaning the platen roller surface, make sure that the platen roller surface and the surfaces of the poultice material 1b and dry cloth material 1c are in contact with each other.
Set the cleaning sheet 1 and run it. Then, the ink and the like adhering to the platen roller surface are dissolved in a solvent such as alcohol that has been soaked in the compress material 1b, and then passed through the dry cloth material 1c to be wiped off.

If the cleaning sheet 1 is made continuous and has perforations so that it can be cut at any position, it is convenient to use only the required amount and store the rest.

In the above embodiment, the platen is a roller, but the same effect can be obtained with a flat platen.

Further, FIG. 3 shows a compressed material 5 and a dry cloth material 6 housed in a case 7 and detachably arranged on the outer peripheral surface of the platen roller 2. The additional effect is that it is easy to handle and can be constantly cleaned even during printing.

Further, FIG. 4 shows another embodiment in which the poultice material 5 and the dry cloth material 6 of FIG. 3 are rollers, and the same effect is achieved.

Next, in FIG. 5, the drive gear 2a of the platen roller 2 and the compress roller gear 5a at one end of the compress roller 5 are engaged, and the compress roller gear 5 and the dry cloth roller gear 6 at one end of the dry cloth roller 6 are engaged. As a result, the rotation of the platen roller 2 and the dry cloth roller 6 is reversed, thereby further improving the cleaning power.

〔Effect of the invention〕

As described above, according to the present invention, the platen roller surface and print head surface can be easily and reliably cleaned by running the cleaning tool equipped with a poultice material and a dry cloth material in the same manner as during printing.

[Brief explanation of the drawing]

1 and 2 show one embodiment of the present invention, in which FIG. 1 is a perspective view showing a cleaning sheet, FIG. 2 is a perspective view showing a state in which a cleaning plate is attached to a printing device, and FIG. 4 and 5 are a sectional view showing another embodiment of the present invention, and FIG. 6 is a perspective view showing a printing section of a conventional printing device. In the drawings, reference numeral 1 indicates a cleaning sheet; 1b is a compress material, 1c is a dry cloth material, 2 is a platen roller, 3 is a head, 5 is a compress material, and 6 is a dry cloth material.In addition, the same reference numerals in the drawings indicate the same or equivalent parts.

Claims (1)

[Claims] In a printing device that prints on paper by sandwiching the paper between a print head and a platen, a wet cloth material and a dry cloth material are provided for alternately contacting the platen surface to clean paper dust and the like adhering to the platen surface.
