JPH024527A - Ink transfer type head pin - Google Patents

Abstract

PURPOSE:To eliminate the variation of a printing density even if ink is used for a transfer of long period by mounting therein a tip immersed with the ink at the end of a pinlike cylinder in which the ink is always supplied in a printing head for a printer. CONSTITUTION:Ink is always supplied from an ink tank to a pinlike cylinder 3, and a tip 1 made of an immersing element such as sponge or the like immersed with the ink is mounted therein at the end of the cylinder 3. In this case, the tip 1 is so provided that the printing face 1a of the tip 1 slightly protrude from the end of the cylinder 3. Thus, even a specific head pin of the pins disposed in a matrix is hit, the tip 1 at the end is pressed to a sheet thereby to transfer and print the ink 2 immersed at the tip 1 to and on the sheet 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to printers, and more particularly to the structure of print head pins.

[Conventional technology]

Conventionally, this type of print head performs printing by hitting a head pin onto an ink-coated ink ribbon to transfer the ink from the ink ribbon onto paper.

[Problem that the invention seeks to solve]

Since the above-mentioned conventional printer head uses an ink ribbon, it has the disadvantage that the print becomes faint after long-term use. Another disadvantage is that the ink ribbon is a consumable item.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide an ink transfer type RAD bin that performs printing without using an ink ribbon.

[Means for solving problems]

The present invention is an ink transfer type head pin used in a printer, which is characterized by having a tip made of an impregnated body impregnated with ink at the tip of a pin-shaped cylinder to which ink is replenished.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

1(a) and (b), the present invention includes a tip 1 made of an impregnated material such as a sponge impregnated with ink at the tip of a pin-shaped cylinder 3 into which ink 2 is replenished. The printed surface 1a of the chip 1 is slightly protruded from the tip of the cylinder 3.

The ink transfer type head pins according to the present invention shown in FIG. 1 are arranged in a print head, for example, in a matrix, and as shown in FIG. Connect 4. The cylinder body 3 is constantly replenished with ink 2 from an ink tank 4, and based on the print command, a specific helad pin in the matrix arrangement is fired toward the paper, the tip 1 at the tip is pressed against the paper, and the tip is removed. Printing is performed by transferring the ink impregnated in No. 1 onto paper.

〔Effect of the invention〕

As explained above, by using an ink transfer type head, the present invention has the effect that the printing density does not change even after long-term use, and printing can be performed without using an ink ribbon.
