Abstract

PURPOSE:To arrange so that an unintended ink leakage from an ink tank may not occur by providing a structure where an air layer around an ink-impregnated member is linked to an atmosphere through an air port in a tank. CONSTITUTION:A wire guide 13 is assembled into a circumferential groove 12a and a gap is provided by the combination of both parts as indicated by A and B. Furthermore, a gap between wire 11 and a wire guide aperture 13a of the wire guide 13 is insignificant. Ink is conducted by capillary pressure from an ink tank 2 to the tip of the wire 11 through an ink guide groove 12b of an ink supply guide 12 and the gap A, B between the circumferential groove 12a and the wire guide 13. Surplus ink in front of the wire guide 13 is sucked by capillary pressure into a thin recovery groove 13b of V-shape cross section provided in the front and side. For this reason, the ink never overflows to spoil the recording paper and instead, is recycled to the ink supply guide 12.

As shown by arrow A in the figure, the ink expands without applying any pressure and is discharged from the air hole, but the air layer sealed with ink moves the surrounding ink as shown by arrow B. It expands while causing it. If this movement of ink reaches the ink supply port, unintentional ink outflow occurs, causing ink stains on the recording paper, and furthermore, ink flowing into the mechanical section of the printer head, resulting in FIA malfunction.

A magnetic circuit is constituted by the yoke 18, the yoke plate 19, and the plunger 15. The movement of the plunger 15 is transmitted to the wire 11 via the clamper 14. The wire driving device described above is covered by a cover 21 and the operating length of the clamper 14 is regulated. During standby, the wire length is set such that the tip end surface of the wire is located deeper than the tip end surface of the wire guide 15, and the meniscus of ink formed at the front of the wire guide hole 16-a covers the wire tip end surface.

As a result, the clamper 14 to which the plunger 15 is fixed rotates, and the wire 11 engaged at its tip protrudes. The tip of the wire pierces the ink meniscus, causes ink to adhere to the tip, and collides with a recording paper (not shown) to transfer the ink to the recording paper. In the wire standby state, the distal end surface of the wire 11 is located inside the end surface of the wire guide 15, and an ink meniscus is formed in front of the wire distal end surface, so that ink sequentially adheres to the wire distal end surface as the wire moves in and out.

ンク外部に流出される力を持たない。Since the ink tank of the present invention has the above-described structure and the ink impregnated member is supported by the protrusion of the tank body, an air layer exists around the ink impregnated member without being separated from the outside air through the air port. Furthermore, there is almost no air space sealed by ink within the ink-impregnated member. Therefore, even if the air inside the tank expands due to a rise in temperature or a drop in air pressure, it is quickly discharged to the outside from the air port, and the pressure inside the tank remains constant, equal to the atmosphere, and is then flowed out to the outside of the ink tank. have no power.

このように本発明のインクタンクは温度変化や気圧変化

意図しないインクの流出がないという効果がある。<Effects> As explained above, the ink tank of the ink-type wire dot printer of the present invention has a structure in which the air layer around the ink-impregnated member is not sealed by ink and is connected to the outside air through the air port provided in the tank. Yes, and by impregnating the ink-impregnated member with ink at low pressure or high temperature range, there is almost no air space sealed by ink in the ink-impregnated member, so there is no unintentional ink leakage from the ink tank. There is an effect.
