を得ている。In the conventional device, as in JP-A-58-194.567, a negative pressure suction device is arranged in a direction perpendicular to the capping direction, and a single lever device is used to draw the capping device to the nozzle side. In order to move forward and operate the negative pressure suction device, a connecting pin and a cam groove are provided between the lever and the capping device, converting the recovery action of the lever into the forward movement of the capping device, and moving the capping device in two directions. has gained the operational power of
上記従来技術は、レバーの操作力が増大した場合の連結
用ピン、及びカム機構の摩耗について配慮されておらず
、回転軸にがたつきを生じ、負圧吸引装置に操作力をス
ムースに伝達できなくなる恐れがあった。The above conventional technology does not take into account the wear of the connecting pin and cam mechanism when the operating force of the lever increases, which causes rattling in the rotating shaft and prevents the operating force from being smoothly transmitted to the negative pressure suction device. There was a fear that I wouldn't be able to do it.
本発明の目的は、カム機構後右しない一つのレバーの操
作で、キャッピング装置のノズル側への前進と負圧吸引
装置の作動をスムースに行なうことができるインク吐出
回復装置を提供することにある。An object of the present invention is to provide an ink ejection recovery device that can smoothly advance a capping device toward the nozzle side and operate a negative pressure suction device by operating a single lever that does not turn after the cam mechanism. .
上記目的は、負圧吸引装置の操作力がキャッピング方向
と同一方向に作用するように負圧吸引装置を配慮し、一
つのレバーの回転動作範囲内にキャッピング装置と負圧
吸引装置の作用領域を設けることにより達成される。The above purpose is to consider the negative pressure suction device so that the operating force of the negative pressure suction device acts in the same direction as the capping direction, and to place the action area of the capping device and the negative pressure suction device within the rotational movement range of one lever. This is achieved by providing
キャッピング装置は、負圧吸引装置の動作方向と同一方
向に動作するよう構成されており、かつ、キャッピング
装置を操作するレバーの回転範囲内に作用領域を設けて
いるので、キャッピング終了後、更にレバーを回転させ
ると、負圧吸引装置内に負圧が発生し、ヘッドノズルよ
り、インクを吸引することが可能である。The capping device is configured to operate in the same direction as the negative pressure suction device, and has an operating area within the rotation range of the lever that operates the capping device. When rotated, negative pressure is generated within the negative pressure suction device, and ink can be suctioned from the head nozzle.
以上によって、キャッピング装置と負圧吸引装置は、作
用方向を同一方向として一つのレバーにより操作が可能
であるので、操作力をスムースに伝達できなくなる恐れ
がなくなる。As described above, since the capping device and the negative pressure suction device can be operated by one lever with the same direction of action, there is no possibility that the operating force cannot be transmitted smoothly.

ヘッドノズル１ａより、インクや気泡等が吸引される。The negative pressure suction device 5 is attached to the guide 3 as shown in FIGS. 2 and 3, and generates negative pressure by pushing the piston 5b in the same direction as the moving direction of the cap case 2 during capping. Therefore, when the slide photographing device 6 is moved in the direction of the head 1 after the character 4 ping is completed, the negative pressure suction device 5 can be activated. The negative pressure suction device 5 has a cylinder 5 as shown in FIG.
a, piston 5b, upper seal 5e, and lower seal 5
On the side surface of the cylinder 58, there is provided an exhaust port 5d, a valve mechanism consisting of a valve 5c for opening and closing the exhaust port 5d, and a valve seal 5h, and a suction port 5g. When the piston 5b is pushed, the valve 5c closes, and the upper seal 5e and lower seal 5f are closed.
Negative pressure is generated in the space formed by the lower seal 5.
Negative pressure is maintained until f passes through the suction port 5g. Here, the suction chup 11 connected to the suction port 5g is
It is connected to the cap rubber 7 that is in close contact with the front surface of the head 1 during capping, and when the suction port 5g is under negative pressure,
Ink, air bubbles, etc. are sucked from the head nozzle 1a.

で、カム機構を必要とせず機構部を簡素化できる。According to this embodiment, by one lever operation via the slide camera 6, the cabling device is moved forward toward the nozzle side, and
It is possible to operate the negative pressure suction device, and since the operating direction when the negative pressure suction device is activated is the same as the capping direction, the operating force can be transmitted smoothly and the rotational movement of the lever can be directed in one direction. Since it is only necessary to convert the motion into a linear motion, a cam mechanism is not required and the mechanism can be simplified.
