問題点があった。Conventional printers were configured as described above, so
There is no means to remove dust that originally adheres to the surface of the thermal paper or dust that adheres when passing through the paper guide 161.
If this dust is heated with a thermal head while it is still attached, the color will disappear in the form of white dots instead of just the part where the dust has adhered, and in extreme cases, the dust may get caught in the thermal head. , there was a problem that the color came out in a linear manner.
この発明は上記のような問題点を解決するためになされ
たもので、感熱紙がサーマルヘッドで加熱される直前に
感熱紙表面のごみを取り除くことのできるごみ除去装置
を得ることを目的とする。This invention was made to solve the above-mentioned problems, and an object of the present invention is to provide a dust removal device that can remove dust from the surface of thermal paper immediately before the paper is heated by a thermal head. .
この発明に係るプリンターのごみ除去装置は感熱紙表面
のごみを吸着する補助ローラと、この補助ローラに付着
したごみを取り除くブラシとを設けたものである。The dust removal device for a printer according to the present invention is provided with an auxiliary roller that adsorbs dust on the surface of thermal paper, and a brush that removes dust adhering to the auxiliary roller.
この発明における補助ローラはゴムでできているため、
かなり微細なごみに至るまで吸着することができ、また

にする。Since the auxiliary roller in this invention is made of rubber,
It can attract even the smallest particles of dirt, and the brush that is strongly pressed against this auxiliary roller removes the dirt adhering to the auxiliary roller, keeping it clean at all times.

is an auxiliary roller, and the auxiliary roller (71 itself is not driven), but the drive roller (71) rotates in such a way as to wind up the thermal paper Ill at 310 rotations.
Like 31, it is made of rubber. (8) is a brush whose bristles are directed downward in order to remove dust from the auxiliary roller (7) during the rotation VcF5 of the auxiliary roller +71. Is 19+ brush 18? The brush (8) is made of an elastic plate metal that supports the brush (8) and is fixed by screws with elasticity as shown in the figure, and is pressed against the auxiliary roller 171 with a constant pressure.

るまで、吸着して取り除く。Next, the operation will be explained. The nine thermal paper 121 passing through the paper guide (61) is rolled up and fed by the drive roller (31. At this time, the !8 thermal paper il+ passes through the auxiliary roller 171 in the tube that reaches the thermal head (4) M. It is sandwiched between the drive rollers (31 and the auxiliary rollers 171
contacts the printing surface of the thermal paper I11. Auxiliary roller (7
) itself is not driven, but rotates in accordance with the rotation of the drive roller (3), and traces the surface of the thermal paper one after another. The auxiliary roller (71ri repellent roller (31 and 1@) is made of rubber and absorbs and removes fine dust on the surface of the thermal paper (!10) that it comes into contact with.
こうして、紙送りされた分、補助ローラ１７１が回転し
どんどん感熱紙１２１０表面のごみｔｉｌｔ除去する。In this way, the auxiliary roller 171 rotates as much as the paper is fed, gradually removing dust from the surface of the thermal paper 1210.

以上のようにこの発明によれば、感熱紙表面のごみを取
り除くようにしたので、印字画の一部欠落などを防止で
きるという効果がある。As described above, according to the present invention, since the dust on the surface of the thermal paper is removed, it is possible to prevent a portion of the printed image from being missing.
