Abstract

PURPOSE:To prevent the drying and solidification of ink, to facilitate the maintenance of a jet nozzle and to secure stable printing quality, by mounting a cap composed of a shape memory alloy to the leading end of the jet nozzle and controlling the shape thereof by a heater. CONSTITUTION:When a printer is not operated, the power source of a printer is turned OFF and the supply of a current to a heater 103 is stopped and a cap 102 composed of a shape memory alloy closes the outlet of a nozzle by the falling of temp. At the time of the operation of the printer, a current is supplied to a heater 203 and the shape of a cap 202 made of a shape memory alloy changes by the rising in temp. to open the outlet of a nozzle 201.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、インクジェットプリンタのインク乾燥防止機
構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ink drying prevention mechanism for an inkjet printer.

〔従来の技術〕[Conventional technology]

従来インクジェットプリンタの噴射ノズルの先端は、イ
ンクと空気を遮断するような機構とはなっていなかった
。Conventionally, the tip of the jet nozzle of an inkjet printer did not have a mechanism to shut off ink and air.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

このため、プリンタが長期間非動作状態にある場合は、
噴射ノズル先端のインクが空気と触ることにより乾燥・
凝固し、ノズルをふさいでしまうという問題があった。Therefore, if the printer is inactive for a long period of time,
The ink at the tip of the jet nozzle dries when it comes into contact with air.
There was a problem that it solidified and blocked the nozzle.

〔問題点を解決するための手段〕[Means for solving problems]

インクの乾燥を防止する。In the present invention, a cap made of a shape memory alloy is attached to the tip of the injection nozzle of an inkjet printer, and the shape is controlled by a heater, so that the cap blocks ink and air at the tip of the nozzle when the printer is not in operation.
Prevent ink from drying.

〔実施例〕〔Example〕

第１図及び第２図は本発明の実施例である。 1 and 2 are examples of the present invention.
