一連の動作の処理速度を速くし、かつ小型化を計ったイ
ンクジェットプリンタに関する。Detailed Description of the Invention [Industrial Application Field] The present invention relates to an on-demand inkjet printer that ejects ink droplets according to print information, and particularly to an on-demand inkjet printer that increases the processing speed of a series of operations other than printing, and This article relates to an inkjet printer designed to be miniaturized.
インクジェットプリンタは極めて低騒音で、高速印字が
可能のほか、安価な普通紙が使え、現像、定着を必要と
せず、漢字、図形等の記録が行えるものである。Inkjet printers are extremely low-noise, capable of high-speed printing, use inexpensive plain paper, do not require development or fixing, and can record kanji characters, figures, etc.
印字ヘッドは圧電素子等の電気機械変換素子を備え、該
圧電素子に電気信号を力■えヘッド内に発生した圧力波
によりノズルよりインクを噴射し印字する。The print head includes an electromechanical transducer such as a piezoelectric element, and when an electric signal is applied to the piezoelectric element, pressure waves generated within the head are used to eject ink from a nozzle to print.

ので、小型化されたインクジェットプリンタが要望され
ている。However, due to the principle of printing, the ink used tends to dry out and cause nozzle clogging, so it is necessary to stabilize the ink particles ejected from the nozzle, and to ensure that it is stable for long-term use and does not clog the nozzle. . Therefore, there is a need for an inkjet printer that satisfies these requirements and is more compact because the device is often placed on a tabletop.
従来のインクジェットプリンタは、例えば第4図に示す

リフジ6と、サブタンク2にインクを加圧するポンプ7
を備える。A conventional inkjet printer has an ink supply system, for example, as shown in FIG. It will be done. In addition, a check valve 5 that prevents the ink in the sub tank z from flowing back into the main tank 3 side, a carriage 6 that moves the head 1, and a pump 7 that pressurizes the ink in the sub tank 2.
Equipped with

路10を通り、ノズル11よりインク滴を噴射する。圧
力室8のインクはサブタンク2より補給され、サブタン
ク2へのインクはメインタンク3と接続した取り入れ口
12より供給される。The head 1 and the sub-tank 2 are integrally constructed as shown in FIG. 5, and the ink in the pressure chamber 8 is driven by a piezoelectric element 9 to pass through a conduction path 10 and eject ink droplets from a nozzle 11. Ink in the pressure chamber 8 is replenished from the sub-tank 2, and ink to the sub-tank 2 is supplied from an intake port 12 connected to the main tank 3.
サブタンク2はケース13に内接した袋で、サブタンク
2内のインク量は検出子14で制御される。なお、15
はホトセンサである。The sub-tank 2 is a bag inscribed in a case 13, and the amount of ink in the sub-tank 2 is controlled by a detector 14. In addition, 15
is a photo sensor.
又、ノズル11では、インクが乾燥し目詰りを起し易い
ので、インクの乾燥を防ぐ為に、第6図に示すようなキ
ャッピング機構16がある。Further, since the ink in the nozzle 11 tends to dry and become clogged, a capping mechanism 16 as shown in FIG. 6 is provided to prevent the ink from drying out.
キャッピング部材は図示のようにゴム等の突起17で、
ノズル面を非印字位置で覆うように構成される。ヘッド
1はキャリア軸19上を移動するキャリア20に乗り移
動可能に構成される。21は紙を示す。The capping member is a protrusion 17 made of rubber or the like as shown in the figure.
It is configured to cover the nozzle surface at the non-printing position. The head 1 is configured to be movable on a carrier 20 that moves on a carrier shaft 19. 21 indicates paper.
図はキャッピング動作時の状態を示し、印字終了したヘ
ッド1が印字領域以外の場所でキャッピング機構16の
突起17と密接し、ノズル11を保護する。The figure shows the state during the capping operation, in which the head 1 that has finished printing comes into close contact with the protrusion 17 of the capping mechanism 16 in a place other than the printing area, and protects the nozzle 11.
又、ヘッド1を印字領域と異なる位置に移動し、ノズル
11から勢いよくインクを吐出させてノズル部の目詰り
を取り除く機構がある。従来より第7図のようにノズル
11を含むノズル部を覆う管22の中に吐出させる方法
と第8図のようにポンプ23等による回収機能を持つ管
24をノズル11近傍に配し、吐出インクを回収する方
法とがある。Further, there is a mechanism for moving the head 1 to a position different from the printing area and ejecting ink vigorously from the nozzle 11 to remove clogging in the nozzle portion. Conventionally, as shown in FIG. 7, there is a method of discharging into a pipe 22 that covers the nozzle part including the nozzle 11, and as shown in FIG. There is a method for recovering ink.
前者の方法では、回収管22をノズル11面に衝撃を与
えずに密着させる駆動機構が必要で、また吐出インク全
量を回収するのが難しく、ノズル11面にインクの残留
が生じる。また、後者の方法では回収用ポンプ23等の
電磁駆動部品が必要であり、複雑化し、かつ必要空間が
大きい。なお、25は回収槽を示す。The former method requires a drive mechanism that brings the recovery tube 22 into close contact with the nozzle 11 surface without impacting it, and it is difficult to recover the entire amount of ejected ink, resulting in ink remaining on the nozzle 11 surface. Furthermore, the latter method requires electromagnetic drive parts such as the recovery pump 23, making it complicated and requiring a large space. Note that 25 indicates a recovery tank.
そこで、第9図に示すような回収面を偏心ローラにより
形成し、キャッピング機能を併せ持つ目詰り復旧のパー
ジ機構として小型化を図ったものがある。Therefore, there is a system in which a collection surface as shown in FIG. 9 is formed by an eccentric roller, and a purge mechanism for recovering from clogging which also has a capping function is miniaturized.
図において、偏心ローラ22はモータ18により回転可

ッジ駆動機構により移動可能で、目詰り復旧時は印字領
域と異なる図示の位置に移動し、(第4図参照)ポンプ
7の駆動によりサブタンク2内のインクを加圧しノズル
11より勢いよくインクを吐出して目詰りを取り除く。In the figure, an eccentric roller 22 is rotatable by a motor 18, and a capping member 23 is disposed on the eccentric roller 22 to cap the eccentric roller 22 when not printing. The head 1 is movable by a carriage drive mechanism, and when a clog is recovered, it moves to a position shown in the figure that is different from the printing area (see Figure 4), and pressurizes the ink in the sub-tank 2 by driving the pump 7, causing the nozzle 11 to move with force. Eject ink well to remove any clogs.
インクを回収する回収槽24は偏心ローラ22の下部に
あり、インクが偏心ローラ22面に沿って回収される。A collection tank 24 for collecting ink is located below the eccentric roller 22, and the ink is collected along the surface of the eccentric roller 22.
また、ノズル11の目詰り有無を検出する目詰り検出器
25は第9図に示す点線のように印字部(図の紙21の
位置)と偏心ローラ22の間に設けて、目詰り検出を行
い印字が行われる。Further, a clogging detector 25 for detecting whether or not the nozzle 11 is clogged is installed between the printing section (the position of the paper 21 in the figure) and the eccentric roller 22 as shown by the dotted line in FIG. and printing is performed.
目詰り検出器25の箱内部は第10図に示すようにヘソ
1より吐出したインク粒子26が空中を飛翔し検出電極
27への到達を検出する。アンプ28ではインク粒子の
荷電電流を増幅出力する。Inside the box of the clogging detector 25, as shown in FIG. 10, ink particles 26 discharged from the navel 1 fly through the air and detect when they reach the detection electrode 27. The amplifier 28 amplifies and outputs the charging current of the ink particles.

詰りの有無を検出する目詰り検出の機能は各動作毎にヘ
ッド1を移動させる必要があった。その為キャリッジ移
動の為の時間がか\す、処理速度が遅いと云う問題点が
ある。Conventional inkjet printer functions of capping to prevent clogging, purging to restore clogged nozzles, and clogging detection to detect the presence or absence of clogging required the head 1 to be moved for each operation. . Therefore, there are problems in that it takes time to move the carriage and the processing speed is slow.
また、ノズルピッチが小さく、各動作の機能を満足させ
る為には各停止位置精度が要求されると共に、個別ユニ
ットを内臓する為にも大きな空間が必要であるという問
題点がある。Another problem is that the nozzle pitch is small, and in order to satisfy the functions of each operation, precision in each stop position is required, and a large space is required to house the individual units.
さらに、目詰りネ★吊器25はインク粒子26を荷電し
、その荷電電流を検出しているが、インク粒子26が直
径数十μmと極めて小さく電荷量も少ない為ノイズで誤
検出し易(、電極27とノズル11の位置、距離dに影
響されると云う問題点がある。Furthermore, the clogging device 25 charges the ink particles 26 and detects the charging current, but since the ink particles 26 are extremely small with a diameter of several tens of μm and have a small amount of charge, it is easy to falsely detect them due to noise ( , there is a problem that it is affected by the position and distance d between the electrode 27 and the nozzle 11.
上記問題点は前記目詰り検出器を前記印字ヘノドの保護
、復旧機能を持つローラ内部に組み込んで構成し、前記
ノズルの保護、目詰り検出、目詰り復旧の印字以外の一
連の各動作を印字ヘッドを動かすことなく行う本発明の
インクジェットプリンタにより解決される。The above problem is solved by incorporating the clogging detector inside the roller that has the printing nozzle protection and recovery function, and printing a series of operations other than the nozzle protection, clogging detection, and clogging recovery printing. This problem is solved by the inkjet printer of the present invention, which operates without moving the head.
即ち、印字ヘッド保護の為のキャッピング、目詰りヘッ

て行う必要がなく、印字ヘッドを停止させた状態で行う
ことが出来る。従って、各動作毎に印字へフド1を移動
させる為のキャリフジ移動時間がないので、処理速度が
速い。That is, by having a capping mechanism for protecting the print head and a purge mechanism for recovering a clogged head on the circumference of the eccentric roller, and storing a clogging detector inside the roller, a series of operations other than printing, i.e. The operations of nozzle protection, clogging detection, and clogging recovery can be performed with the print head stopped, without the need to move the print head as in the past. Therefore, there is no time for moving the carriage to move the lid 1 to print for each operation, so the processing speed is high.
また、各機能が1つローラに設けられているので、各動
作の停止位置精度が出し易く各機能を満足させ易いと共
に各機能のユニットを配置するスペースは小さくなる。Furthermore, since one roller is provided with each function, it is easy to achieve stop position accuracy for each operation, it is easy to satisfy each function, and the space for arranging units for each function is reduced.
さらに、目詰り検出器25が偏心ローラ内にあり、電極
25とノズル11の位置、距離dに影響されることはな
いので、検出精度の安定が図れる。Furthermore, since the clogging detector 25 is located inside the eccentric roller and is not affected by the position and distance d between the electrode 25 and the nozzle 11, the detection accuracy can be stabilized.
以下、本発明の要旨を図面により具体的に説明する。 Hereinafter, the gist of the present invention will be specifically explained with reference to the drawings.
