Benefits of technology

[0010]An advantage of some aspects of the invention is that it provides a waste liquid collector which can be detachably mounted on the device discharging a waste liquid and is capable of ensuring appropriate connection between a collector-side connection terminal and a device-side connection terminal when the waste liquid collector is mounted on the device.

Problems solved by technology

Here, an absorption capability of the waste ink absorbing member is limited.
Therefore, when the absorption capability reaches the limit, an absorption efficiency of the waste ink may decrease.
In this case, the contact surfaces of both the connection terminals may be deviated from each other in a rotation direction of the waste ink tank, thereby causing a contact failure.
Moreover, when the contact surfaces of both the connection terminals may be deviated from each other in the rotation direction of the waste ink tank during the rotation and the contact surfaces come in contact with other, the contact surfaces of both the connection terminals may be damaged.
Accordingly, even though the contact surfaces of both the connection terminals again come in contact with each other later, the contact failure may be caused.

first embodiment

[0061]Hereinafter, an ink jet printer which is an example of a liquid ejecting device including a waste liquid collecting system in which a waste liquid collector according to the invention is detachably mounted will be described with reference to FIGS. 1 to 11 according to a first embodiment. “Front and rear directions”, “upper and lower directions”, and “right and left direction” in the following description refer to “front and rear directions”, “upper and lower directions”, and “right and left direction” indicated by arrows in FIGS. 1 to 3, unless particularly mentioned.

[0062]As shown in FIG. 1, an ink jet printer (hereinafter, referred to as “a printer) 11 as a liquid ejecting device according to this embodiment includes a frame 12 having a rectangular shape in plan view. A platen 13 extends in the right and left direction inside the frame 12. A sheet-feeding mechanism which is disposed above the platen 13 and includes a sheet-feeding motor 14 feeds a print sheet P from the rear...

second embodiment

[0173]Next, a second embodiment of the invention will be described with reference to FIG. 12. In the second embodiment, since only a formation location of the air communication hole 90 is different from that in the first embodiment and the other configuration is the same, the air communication hole 90 will be mainly described below. In addition, the same reference numerals are given to the same constituent elements and repeated description is omitted.

[0174]In the waste ink tank 27 according to this embodiment, as shown in FIG. 12, the air communication hole 90 is formed at the substantially center in the longitudinal direction of the film member 46. In addition, when the discharge unit 97 of the cylindrical body 73 is inserted into the container member 44 from the connection port 57 of the waste ink tank 27, a distance Y between the front end opening 76a and the air communication hole 90 is configured to be shorter than a distance X between the connection port 57 and the front end o...

third embodiment

[0213]Hereinafter, an ink jet printer which is an example of a liquid ejecting device including a waste liquid collecting system in which a waste liquid collector according to the invention is detachably mounted will be described with reference to FIGS. 1 to 11 according to a first embodiment. “Front and rear directions”, “upper and lower directions”, and “right and left direction” in the following description refer to “front and rear directions”, “upper and lower directions”, and “right and left direction” indicated by arrows in FIGS. 1 to 3, unless particularly mentioned.

[0214]As shown in FIG. 1, an ink jet printer (hereinafter, referred to as “a printer) 11 as a liquid ejecting device according to this embodiment includes a frame 12 having a rectangular shape in plan view. A platen 13 extends in the right and left direction inside the frame 12. A sheet-feeding mechanism which is disposed above the platen 13 and includes a sheet-feeding motor 14 feeds a print sheet P from the rear...

Abstract

A waste liquid collector is detachably mounted on a device including a discharge unit discharging a waste liquid and stores the waste liquid discharged from the discharge unit when the waste liquid collector is mounted on the device. The waste liquid collector includes: an opening through which the discharge unit is inserted or extracted at the time of mounting or detaching the waste liquid collector on or from the device; a collector-side connection terminal which comes in contact with a device-side connection terminal included in the device when the discharge unit of the device is inserted into the opening; and a positioning unit which positions the collector-side connection terminal to come in contact with the device-side connection terminal when the waste liquid collector is mounted on the device.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The entire disclosure of Japanese Patent Application Nos. 2008-119189, filed Apr. 30, 2008, 2008-119190, filed Apr. 30, 2008, 2008-119191, filed Apr. 30, 2008, 2008-049542, filed Feb. 29, 2008, 2008-049543, filed Feb. 29, 2008, 2008-049541, filed Feb. 29, 2008 are expressly incorporated by reference herein.BACKGROUND[0002]1. Technical Field[0003]The present invention relates to a waste liquid collector which is detachably mounted on a device which includes a discharge unit discharging a waste liquid and is capable of storing the waste liquid discharged from the discharge unit when being mounted on the device.[0004]2. Related Art[0005]In the past, as a liquid ejecting device which ejects a liquid to a target from nozzle openings formed in a liquid ejecting head, an ink jet printer (hereinafter, simply referred to as “a printer”), for example, was well known. In this printer, a so-called cleaning process of forcedly sucking thickened ink wi...
