[0037] In the first embodiment of the present invention, the recording device is an inkjet printer 1 (recording device). as in figure 1 As shown in , the inkjet printer 1 has a housing 1a formed in the shape of a cuboid. Three openings 10d, 10b, and 10c are formed in the front surface of the case 1a in order from top to bottom (in the figure 1 surface on the proximal side of the middle). The doors 1d and 1c are respectively placed in the openings 10d and 10c so as to be flush with the front surface of the casing 1a. The doors 1d and 1c can be opened and closed about a horizontal axis passing through their respective lower edges. The paper supply unit 1b is inserted into the opening 10b. A paper discharge unit 11 is provided on top of the casing 1a. The gate 1d is placed vertically at the same level as the transport unit 21 described later, along the main scanning direction of the inkjet printer 1 (towards figure 1 The far side in the middle) faces the delivery unit 21. ...

[0123] Below, will refer to Figure 11An ink cartridge 240 according to a second embodiment of the present invention is described. In the ink cartridge 240 according to the second embodiment, the ink delivery tube 43 has a tube 244 and a tube 45 fitted into the tube 244 similarly to the structure in the first embodiment. However, the portion of the tube 244 in which the tube 45 is fitted is formed longer than in the first embodiment so that the ink outlet 46 a is closer to the annular flange 47 formed on the end of the tube 244 . A light sensor 266 (first detection unit) is also placed in the housing 41 in the second embodiment to detect the open and closed states of the first valve 50 . The light sensor 266 can be constituted by, for example, a reflective optical sensor having a light emitting element and a light receiving element. In this case, a reflective surface capable of reflecting light is formed on at least part of the spherical member 52 . The light sensor 266 is ...

[0134] will refer to Figure 12-13 An inkjet printer 300 (recording device) and an ink cartridge 340 according to a third embodiment of the present invention will be described.

[0135] In the inkjet printer 1 of the first embodiment, each ink cartridge 40 is directly connected to the corresponding inkjet head 2 via the tube 102 .

[0136] However, according to the inkjet printer 300 of the present embodiment, the sub-tank 310 is provided between each ink cartridge 40 and the corresponding inkjet head 2 . The sub-tank 310 is used to separate air from ink and to form a pressure difference between the sub-tank 310 and the inkjet head 2 .

[0137] The inkjet printer 300 of the present embodiment is the same as the inkjet printer 1 of the first embodiment except that the inkjet printer 300 is provided with an ink supply system described below and the inkjet printer 300 operates as described below. The ink cartridge 340 of this embodiment is the same as the ink cartridge 40 of th...

Abstract

An ink box, a recording apparatus and a method used for controlling the recording apparatus are disclosed. The ink box comprises an ink accommodating unit and a storage unit. The ink accommodating unit is configured to contain ink. The storage unit is configured to store time length data indicating time length occupied in the movement of the ink box from a first position to a second position which is different from the first position. The first position and the second position are limited in an installation unit in the recording apparatus. When the ink box is mounted in the installation unit, the ink box arrives at the first position before arriving at the second position. The recording apparatus comprises the ink box. Through comparing a time length actually occupied in movement of the ink box from the first position to the second position in the installation unit of the recording apparatus with the time length indicated by the time length data stored in the storage unit, whether the ink box is installed in the ink box with high speed is known, and if that the ink box is installed with high speed is known, a recording head is forced to spray ink. Thus the recording head maintains an ideal ink injection characteristic.

Description

technical field [0001] The present invention relates to an ink cartridge, a recording device and a method for controlling the recording device. Background technique [0002] US Patent Application Publication US2005 / 0068382A1 describes an ink cartridge containing an ink bag. A valve is attached to the ink bag to control the supply of ink to the recording device. When a user installs the ink cartridge into the recording device, the ink supply needle provided in the recording device opens the ink bag valve, thereby allowing the ink in the ink bag to be supplied to the recording device through the ink supply needle. [0003] US Patent Application Publication US2005 / 0212874A1 describes an inkjet printer in which a subtank is provided between a maintank and an inkjet head. The sub-tank is used to separate air from ink and to create a desired pressure head difference between the inkjet head and the sub-tank. [0004] However, if the user quickly or suddenly installs the ink cart...
