[0038] In the first embodiment of the present invention, the recording apparatus is an ink jet printer 1 (recording apparatus). as in figure 1 As shown in , the inkjet printer 1 has a housing 1a formed in the shape of a rectangular parallelepiped. Three openings 10d, 10b, and 10c are formed in the front surface of the casing 1a in this order from the top to the bottom (at figure 1 surface on the proximal side). The doors 1d and 1c are placed in the openings 10d and 10c, respectively, so as to be flush with the front surface of the housing 1a. The doors 1d and 1c can be opened and closed about a horizontal axis through their respective lower edges. The paper supply unit 1b is inserted into the opening 10b. A paper discharge unit 11 is provided on the top of the casing 1a. The door 1d is placed in the vertical direction at the same level as the conveyance unit 21 described later, along the main scanning direction of the inkjet printer 1 (towards the figure 1 The distal sid...

[0124] In the following, it will be referred to Figure 11The ink cartridge 240 according to the second embodiment of the present invention is described. In the ink cartridge 240 according to the second embodiment, the ink delivery tube 43 has the tube 244 and the 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 46a is closer to the annular flange 47 formed on the end of the tube 244 . The optical sensor 266 (first detection unit) is also placed in the housing 41 to detect the open and closed states of the first valve 50 in the second embodiment. The light sensor 266 may be constituted by, for example, a reflective optical sensor having a light emitting element and a light receiving element. In this case, a reflection surface capable of reflecting light is formed on at least part of the spherical member ...

[0135] will refer to Figure 12 -13 describes the ink jet printer 300 (recording apparatus) and the ink cartridge 340 according to the third embodiment of the present invention.
[0136] 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 .
[0137] 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 the ink and to form a pressure head difference between the sub-tank 310 and the inkjet head 2 .
[0138] 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 the present embodiment is the same as the ink c...
