Abstract

PURPOSE:To enhance printing quality by removing the contaminant of a printing head lowered in its printing quality, by allowing abrasive particles having a diameter smaller than the distance between electrode pins to fly out from the surface of an adhesive. CONSTITUTION:Abrasive particles 1 having a diameter (d) are allowed to fly out to a base film 3 from an adhesive. The diameter (d) of the abrasive particles 1 is made smaller than the distance (c) between electrode pins 5. A printing head to which a contaminant 6 is adhered between the electrode pins 5 thereof is pressed to a cleaning tape to be moved to the direction shown by an arrow (a) and the abrasive particles 1 are allowed to enter between the electrode pins 5 to extrude the contaminant 6 outwardly. The printing head is pressed to the cleaning tape at a certain angle from the aspect of a printing mechanism but, because the silicone rubber 8 present on the back surface of each electrode pin 5 has flexibility, the resistance at the time of the extrusion of the contaminant 6 to the outside is not generated too much.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning tape for removing dirt from a print head of an electric thermal transfer printer.

[Problem that the invention seeks to solve]

In an electric thermal transfer printer, the print head generates heat on the ribbon and moves while rubbing on it, so dirt from the ribbon etc. forms a layer between the electrode pins, resulting in poor print quality [Means for solving the problem] The present invention The cleaning tape uses abrasive grains with a diameter smaller than the distance between the electrode pins that are projected from the adhesive surface to remove dirt from the print head.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows a cleaning tape according to an embodiment of the present invention. Abrasive grains 1 having a diameter of d are projected onto a base film 3 from an adhesive 2. The diameter d of the small particles 1 is smaller than the distance C between the electrode pins 5 shown in FIG. The print head with dirt 6 adhering between the electrode pins 5 as shown in FIG. Fourth
By pressing the cleaning tape of the present invention as shown in the figure and moving it in the direction of arrow a, the abrasive grains 1 enter between the electrode pins 5 and push out the dirt 6. Due to the printing mechanism, the print head is pressed against the cleaning tape at a certain angle as shown in Figure 3, but since the silicone rubber 8 on the back of the electrode pin 5 is flexible, the dirt 6 is pushed out. [Effect of the invention] As explained above, the diameter d is smaller than the distance mc between the electrode pins 5.
The use of the cleaning tape of the present invention in which small abrasive grains 1 are made to protrude beyond the surface of the adhesive 20 has the effect of removing stains from the print head that have caused poor print quality and improving the print quality.
