The main body side tube supporting portion 93 is disposed facing the fixed piping path, and the main body side side ink tubes 72 are arranged side by side in the horizontal direction on the main body side tube supporting portion 93. In addition, the main body side tube supporting portion 93 has a space forming portion 211 (i.e., a accommodating portion of the accommodating tube portion) which forms a space for the root body side ink tube 72 to be individually bent downward. 8; a pair of front and rear upstream (four) lead portions 212 and a downstream side guide portion 213, which guide the main body side ink officer 72 to the space S; and the floating prevention portion 214, which is disposed on the downstream side guide. Around P 213, the 6434 body floats on the bottom of the ink tube μ caused by the bending of the M434681. The space forming portion 211 is formed in a box shape in which the space S of the base-body-side ink tubes 72 is individually bent downward (that is, the direction orthogonal to the fixed pipe path), and has four front and rear wall bodies 215 . The details are described below, but the length error of the base body side ink tube 72 is accepted by causing the 6 radical side ink tubes 72 to be individually bent in the space 3. The upstream side guide portion 212 has an R-shaped guide surface 216, and guides the body side ink tube 7 2 to the space S so as to be lowered. On the other hand, the downstream side guide portion 213 constitutes a guide surface 217 which supports the base body side ink member 72 on the rear two portions before the height is different, and guides the body side ink tube from the space § in a rising manner. 72. The body side ink tubes 72 are guided into the space S by the pair of guide faces 2, 6, 21, and are guided in a space of "u" in the space s. The floating blocking portion 2 14 has a plurality of limiting pieces 22 1 and a plurality of blocking protrusions 222 ′′. The plurality of limiting pieces 221 are erected around the downstream side guiding portion 213 , and are individually paired with the 6 base body side ink tubes. 72 is limited in width, and the plurality of blocking protrusions 222 are protruded on the side of the plurality of restriction pieces 221 and are prevented from floating. A plurality of restriction pieces 22 1 are respectively disposed at two ends of the base-body side ink tube 72 and between the body-side ink tubes 72. On the other hand, a plurality of restrictions are imposed on the upper end of the 2 2 2 line. The sheet 2 2 1 is protruded from the upper side of each of the restricting pieces 221 facing the side and the main body side ink tube 72. Further, each of the blocking dogs 222 is formed to a length such that the main body side ink member 72 is pressed in the width direction to enter the state between the plurality of restriction pieces 221 from the upper side and is in a free state. Fall off on the upper side. 16 M434681 Here, a method of accepting the length error of the main body side ink tube 72 using the space s will be described with reference to Fig. 9 . (6) The length of the base-side ink tubes 72 differs from each other by the difference in error or coiling (hereinafter, simply referred to as a length error). When there is a length error in the base-body ink tube 72, the folded-back tube portion 72a is in a state of being misaligned. As a result, when the deformation is followed, there is a disorder in which the radical-side ink tube 72 is disordered, thereby contacting other members. Hey. In particular, when the shape of the main body side ink tube 72 is formed by extrusion molding, the length error of the main body side ink tube 72 is large, which is liable to cause such a problem. On the other hand, in the present embodiment, when there is an error in the length of the ink supply tube 72 on the base body side, the main body side of the region fixed to the front and the rear by the intermediate joint 71 and the upstream side tube fixing portion 121 is provided. The ink tube 72 is disposed in the space S in a shape of "U" which is bent downward in accordance with the amount of error. Fig. 9 is a cross-sectional view showing the body side flap portion 93 when a length error occurs in the main body side ink tube 72. Here, a case is exemplified in which the body side ink tube 23 1 of the nearest front side of # in Fig. 9 has the minimum value of the assumed error range, and the inner side ink tube 223 of the inner side has the central value of the above error range. The length, and further the inner side of the body side ink tube 233, has the length of the maximum value of the above error range. As shown in Fig. 11, the main body side ink tube 231 having a minimum value is substantially piped in a space S. On the other hand, the central-side main-body ink tube 232 and the maximum-sized main-body ink tube 233 are formed to be longer than the minimum-sized main-body ink tube 231, so that the space S is bent downward only by the difference in length. Configuration. In this case, only the difference between the bending and the minimum value is applied, so that the main body side ink tube 233 having the largest value is arranged to be bent more than the center side ink tube 232 having the center value of 17·M434681. As described above, the main body side ink tube 72 in the region fixed to the front and rear by the intermediate joint 71 and the upstream side tube fixing portion 121 is bent on the space S only by the difference from the minimum value of the assumed error range. Thereby, the length of the main body side ink tubes 72 on the upstream side tube fixing portion 121 to the downstream side can be made coincident with each other at the base body side ink tubes 72. Further, for the 6-base side ink tube 72, the space S preferably has a width (side view area: length and/or height) which can accept an error range of the assumed error range. According to the above configuration, the main body side ink tubes 72 can be bent in accordance with the length error amount in the space S in the fixed pipe path, so that the length error of the base body side ink tubes 72 can be received by the non-movable portions. Therefore, the amount of error in the length error does not cause error accumulation in the movable portion, and stabilization of the following deformation of the main body side ink tube 72 can be achieved. Further, the connection to the indirect head 71 can be appropriately performed. Further, by providing a pair of front and rear guide faces 21 6 , 21 7 , 6 , the body side ink tube 72 is smoothly guided into the space S, so that the curvature of the body side ink tube 72 can be made small, so that The ink is stably supplied by reducing the pressure loss. Moreover, the piping of the six-body-side ink tubes 72 in the space S becomes easy. Further, by providing the floating preventing portion 214, it is possible to prevent the main body side ink tube 72 from floating up due to the reaction force at the time of bending, so that the space directly above the main body side ink tube 72 can be effectively used as an installation space for other members. Further, the 'up floating preventing portion 214 integrally includes a plurality of restricting pieces 221 and a plurality of blocking protrusions 222, whereby the floating preventing portion 214 can perform the floating prevention of the main body side ink tube 72 with a simple configuration. With a wide M434681 degree limit. Further, in the present embodiment, the ink reservoirs are disposed outside the apparatus main body 2, and the ink tubes of the respective colors are divided into the storage tank side ink tubes 13 and the main body side ink tanks 72, but the ink may be used. The sump is disposed in the apparatus body 2, and an ink tube is supplied for each color to supply ink. In this case, the body side tube supporting portion 93 receives the length error between the integrated ink tubes. Further, in the present embodiment, the length is bent downward and the length error is received. However, the configuration is not limited thereto as long as it is curved in a direction orthogonal to the direction of the fixed pipe. In other words, the length error may be received by bending upward, or the bending direction may be increased by the main body side ink tube 72 (for example, alternately curved up and down). Further, when the main body side ink tubes 72 are arranged side by side in the vertical direction in the fixed piping diameter, they are bent in either of the horizontal directions to receive a length error. Further, the configuration is not limited to the configuration of being curved in a direction orthogonal to the direction of the fixed pipe, and may be configured to be curved in the direction in which the main-body ink tubes 72 are arranged in parallel, or the meandering direction may be a plurality of directions. The main body side ink tube U has a curved direction which is formed by up, down, left, and right. Further, in the present embodiment, the minimum value of the assumed error range is used as the reference value (minimum reference value), and only the composition of each of the main body side ink tubes 72 is corrected based on the difference (including 〇) from the value. However, it is also possible to use the minimum value in the base body side ink s 72 as a reference value, and only the body side ink tubes M434681 except the main body side ink tubes 72 which are the smallest value from the difference of the values. The composition of 2. Further, in the present embodiment, a large-capacity ink tank 11 having a capacity of several times or ten times that of a conventional ink cartridge is used, but it is only a separate ink tank π with respect to the carriage 51 (so-called escape tray) In the ink tank 11) of the mode, the present invention can also be applied to the ink jet recording apparatus 1 using an ink tank of the same capacity as the ink cartridge.
