ている。 Recently, thermal transfer printers have been widely used. Thermal transfer printers use thermal transfer paper with a base film coated with heat-melting ink on one side.The thermal transfer paper is overlaid on plain paper (PPC), and a thermal head applies heat pulses from the back side of the thermal transfer paper. As a result, the heat-melting ink on the heat-sensitive transfer paper is partially melted and transferred onto plain paper to perform recording. Thermal transfer paper is usually supplied to the printer in a roll, pulled out from the roll to the printing section, and after printing is wound up again onto the roll.

う欠点があつた。 In this type of thermal transfer, the printed characters and figures remain in negative form on the used thermal transfer paper, which creates a new problem in that the used thermal transfer paper must be disposed of properly to maintain confidentiality. I came. One possible solution to this problem is to shred it in a shredder or incinerate it, but thermal transfer paper is extremely thin and it is extremely difficult to shred it in a shredder. cannot be incinerated immediately after
The drawback was that it had to be stored under strict conditions until it was incinerated.

法を提供することを目的とする。 The present invention was made in view of the current situation, and it is an object of the present invention to provide a method for processing used thermal transfer paper that can make characters, figures, etc. on used thermal transfer paper invisible and secretly store them in a simple manner.
以下、添付図面を参照して、本発明を説明す

いておく。 FIG. 1 is a sectional view showing a heater 1 used in the processing method of the present invention. The heater 1 has a heating chamber 3 into which a roll of thermal transfer paper 2 can be placed, an electric heater 4 capable of heating the inside of the heating chamber 3 to 100 to 150° C., a sealing lid 5, and the like. This heater 1 only needs to be able to hold one roll of thermal transfer paper, and has a diameter of 15 mm.
The size is ~20cm and height is 30~50cm, so place it in the room where the thermal transfer printer is located or near it.

保管し、最終的には焼却、廃棄等の処分を行う。 Next, a processing method of the present invention using the heater 1 described above will be explained. A roll of thermal transfer paper 2 that has been used in a thermal transfer printer is placed in a heater 1, and after the lid is closed, heating by an electric heater is started. The heating temperature is set higher than the melting point of the heat-melting ink of the thermal transfer paper. The melting point of hot-melt ink is usually 40-80℃
Therefore, the temperature inside the heater is preferably 100 to 150°C. The thermal transfer paper 2 is heated in the heater 1 until the ink inside is sufficiently melted. Due to this heating, the ink layer containing characters, figures, etc. is fused to the base film in contact with it, causing blocking. Therefore, even if the thermal transfer paper is unwound, characters, figures, etc. are no longer legible. After the thermal transfer paper has been sufficiently heated in this manner, the heating is stopped, the thermal transfer paper is taken out, stored in an appropriate place, and finally disposed of by incineration, disposal, or the like.
なお、上記実施例は、感熱転写紙を容器状の小
さい加熱器１にて加熱したが、本発明はこれに限
定されず、どんな形式の加熱器を用いてもよい。 In the above embodiment, the thermal transfer paper was heated using a small container-shaped heater 1, but the present invention is not limited thereto, and any type of heater may be used.
以上の如く、本発明は使用済のロール状感熱転

に秘密の保持をしうるという優れた効果を有して
いる。 As described above, the present invention simply heats used rolled thermal transfer paper to a temperature higher than the melting point of the ink.
Since it causes blocking and makes the information on the thermal transfer paper unreadable, it has the excellent effect of ensuring that secrecy can be maintained with a simple operation.
