[0038] 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. ...

[0124] 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 ...

[0135] will refer to Figure 12 -13 describes an inkjet printer 300 (recording device) and an ink cartridge 340 according to a 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 ink and to form a pressure 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 this embodiment is the same as the ink cartridge 40 of the first...
