きる感熱式インクロールに関する。[Detailed Description of the Invention] This invention relates to a heat-sensitive ink roll that can draw characters and symbols on tickets, food tickets, labels, stickers, packaging materials, etc. using heated type. .
従迷］四支術
切符・食券等の券売機や、ラベル・シール・包装資材等
に文字や記号を印字するのにインクロールや転写箔が使
用されている。Ink rolls and transfer foils are used to print characters and symbols on ticket vending machines for Shishijutsu tickets, food tickets, etc., and on labels, stickers, packaging materials, etc.
ところが、インクロールで印字した際インクロールが新
しい時は、インクが良く出て印字面を触っただけで手に
インクがつき券売機では不愉快窮まりないものであった
。また、ラベル・シール・包装資材等に使用した場合、
乾燥（＝紙等の基材にインクが吸収）されるまで印字面
が重なって擦り合わないようにしなければ、印字面が読
めないことがあった。However, when printing with an ink roll, when the ink roll was new, the ink came out well, and just touching the printed surface resulted in ink on my hands, which caused an unpleasant experience when using a ticket vending machine. Also, when used for labels, stickers, packaging materials, etc.
The printed surfaces could not be read unless the printed surfaces overlapped and rubbed against each other until drying (=the ink was absorbed by the base material such as paper).
一方、転写箔を使用すれば印字直後でも印字面を触って
も汚れないが、コストがアップしたり、転写箔が切れた
りすると全く印字されずメンテナンスに手間がかかった
。On the other hand, if a transfer foil is used, the printed surface will not be smeared to the touch even immediately after printing, but the cost increases and if the transfer foil breaks, no printing will occur at all and maintenance is time consuming.
そのため、上記インクロールや転写箔に代わるものとし

互に押圧され、基材７に文字等が印字される。Therefore, a method of using a thermal ink roll has become popular as an alternative to the above-mentioned ink roll or transfer foil. When printing characters etc. using a thermal ink roll,
For example, a method as shown in FIG. 1 is often used. In FIG. 1, the ink roll 1 is heated by a heater 2, and the type 3 held in the type holder 4 is alternately pressed against the ink roll 1 and the base material 7 every time it rotates 1.80 degrees. Characters, etc. are printed on the material 7.

The difference (8T''C) between the melting end temperature fT and °C) is large and the ink lacks heat resistance, especially when melting starts at 40 to 50 °C and the strength of the ink weakens. If you rub it with your fingertips, the print will disappear after 2 or 3 times, or if it is rubbed by the guide roll of a ticket vending machine or the guide roll of a packaging line that incorporates a printing machine that prints the date of manufacture, etc., the printed characters will become unclear. Sometimes it became.
