The carriage 153 includes a sub-carriage 50 to which a recording head 152 and the like are attached, and a carriage body 51 to which a damper 159 and the like are attached. The recording heads 152 are arranged in two rows each in the main scanning direction and the sub-scanning direction. Two dampers 159 are provided in two upper and lower stages of the carriage body 51. The four dampers 159 are connected to the ink tubes 158 for a total of eight colors, and temporarily store ink sent from the ink tubes 158. The four recording heads 152 are connected to the four dampers 159, respectively, and eject ink sent from the dampers 159.

  FIGS. 6A and 6B are a perspective view of the sub-carriage 50 to which the recording head 152 and the like are attached as viewed from the upper surface side and a perspective view of the sub carriage 50 as viewed from the lower surface side, and FIGS. FIG. 5 is a perspective view of the sub-carriage 50 with the recording head 152 and the like removed, as viewed from the upper surface side and a perspective view as viewed from the lower surface side. The sub-carriage 50 is formed in a box shape having a relatively shallow bottom formed by bending four sides of a substantially rectangular metal flat plate at a right angle. The four recording heads 152 are arranged in two rows in the main scanning direction and the sub-scanning direction in the bottom surface of the sub-carriage 50, respectively.

  On the bottom surface of the sub-carriage 50, four openings 53 for exposing the nozzle forming surfaces 152a of the four recording heads 152 to protrude from the bottom surface, and an adhesive are poured when the recording heads 152 are temporarily fixed. A hole portion 54 for attaching the recording head 152 and an attachment portion 55 for attaching each recording head 152 are formed. The four openings 53 are formed in a substantially rectangular shape in two rows in the main scanning direction and the sub-scanning direction in accordance with the arrangement of the recording heads 152. The holes 54 are formed in the vicinity of the four corners of each opening 53.

  The attachment portions 55 are formed at two locations on substantially the extension of one diagonal line of each opening portion 53. That is, the substantially rectangular recording head 152 is attached to the sub-carriage 50 at one diagonal portion. The attachment portion 55 has a configuration in which a circular hole 55a is formed, a metal pipe 55b is caulked in the hole 55a, and a substantially U-shaped slit 55c is formed around the hole 55a. When the subcarriage 50 is manufactured by casting, the pipe 55b portion may be integrally formed. In such a configuration, a split pin (auxiliary fastening member) 56 to be described later is inserted into the pipe 55 b, the recording head 152 is placed on the split pin 56, and a screw 57 to be described later is split via the recording head 152. The recording head 152 is fastened to the sub-carriage 50 by being screwed to the pin 56.

  FIG. 8 is a perspective view showing the split pin 56. The split pin 56 is made of plastic or metal, and is formed at a cylindrical portion 56a divided into two in the axial direction, a cutout portion 56b formed at one end of the cylindrical portion 56a, and the other end of the cylindrical portion 56a. A flange portion 56c is provided. The cylindrical portion 56a has a function of pressing the inner peripheral surface of the pipe 55b when the screw 57 is screwed, and is easily spread when the screw 57 is screwed by dividing into two parts. The notch portion 56b has a function as a detent when the screw 57 is screwed. The flange portion 56 c has a function of sandwiching the recording head 152 with the head of the screw 57.

  The cylindrical portion 56a of the split pin 56 is crushed and deformed between the screw 57 and the inner periphery of the pipe 55b when the screw 57 is screwed. In order to prevent the influence of deformation from occurring in the flange portion 56 c that is a connection portion with the recording head 152, the hole of the split pin 56 is enlarged on the flange 56 c side as shown in the cross-sectional view of FIG. As shown in FIG. 10, the axial division of the cylindrical portion 56a is limited to 1/2 to 1/3 on the tip side, the material is POM with glass fiber, It is effective to use a metal such as casting. In addition, as shown in FIG. 11, it is also effective to provide a slope 56d for facilitating insertion of the screw 57 into the step of the hole of the split pin 56, or to make the tip of the screw 57 thinner.

  Here, a procedure for attaching the recording head 152 to the sub-carriage 50 will be described. First, the recording head 152 is placed on the head positioning jig, the sub-carriage 50 is placed on the carriage positioning jig, and the recording head 152 is projected from the opening 53. A nozzle positioning glass plate is placed on the nozzle forming surface 152a of the recording head 152, and the nozzle rows formed on the nozzle forming surface 152a are drawn on the nozzle positioning glass plate by chromium vapor deposition or the like. By adjusting to the nozzle line, the position of the recording head 152 is adjusted. At this time, the position of the recording head 152 is determined by the nozzle positioning glass plate, and a gap remains between the recording head 152 and the sub carriage 50. When the adjustment is completed, the instantaneous adhesive is dropped from the hole 54 into the gap between the recording head 152 and the subcarriage 50 to temporarily fix the recording head 152 to the subcarriage 50. Thereafter, the sub-carriage 50 to which the recording head 152 is temporarily fixed is taken out, and the recording head 152 is completely attached to the sub-carriage 50. This procedure will be described below with reference to the drawings.

  FIG. 9 is a cross-sectional view showing a state when the recording head 152 is attached to the attachment portion 55. As this attachment procedure, first, the split pin 56 is inserted into the pipe 55b from one end side. At this time, since the notch portion 56b of the split pin 56 contacts the rotation stopper, the lower surface of the flange portion 56c of the split pin 56 is separated from the upper end of the pipe 55b by the gap c. Next, the recording head 152 is placed on the flange portion 56 c of the split pin 56, and the screw 57 is screwed to the split pin 56 via the recording head 152.

  When the screw 57 is screwed onto the split pin 56, the two-divided cylindrical portion 56 a expands in the outer peripheral direction and presses the inner peripheral surface of the pipe 55 b, and the flange portion 56 c is between the head of the screw 57. The recording head 152 is sandwiched. Although not shown in the drawing, the inner circumference of the pipe 55b is provided with a groove, hole, or minute unevenness that prevents slipping when the cylindrical portion 56a expands. As the screw 57 is further tightened, the two-divided cylindrical portion 56a comes into pressure contact with the inner peripheral surface of the pipe 55b, so that a load is applied to the recording head 152 sandwiched between the flange portion 56c and the head of the screw 57. The horizontal direction of the recording head 152 can be fixed without being hung. At the same time, in the state where the recording head 152 is sandwiched between the flange portion 56c and the head of the screw 57, the displacement is adjusted by the gap c between the lower surface of the flange portion 56c and the upper end of the pipe 55b. The vertical direction of the recording head 152 can be fixed without applying a load. Furthermore, since the attachment portion 55 can be provided with a spring property by the slit 55c, a minute displacement in the vertical direction when the screw 57 is fastened can be absorbed.

  As described above, since the plurality of recording heads 152 are not brought into direct contact with the sub-carriage 50, even if the screw 57 is tightened, the recording head 152 and the sub-carriage 50 are not greatly displaced, and are determined by the nozzle positioning glass plate. And fixed in the position temporarily fixed by the instantaneous adhesive. Accordingly, the nozzle forming surfaces 152a of the plurality of recording heads 152 can be arranged on the same plane, and the nozzle forming surfaces 152a and the upper surface of the platen 151 can be maintained in parallel. Therefore, it is possible to obtain a multi-head capable of performing high-quality recording with stable ink particle landing positions.

  As described above, according to the carriage 153 of the present embodiment, each recording head 152 is fixed in a state where it does not directly contact the sub-carriage 50 so that the nozzle forming surfaces 152a are arranged on the same plane. Therefore, when each recording head 152 is fixed to the sub-carriage 50, it is possible to prevent the sub-carriage 50 from interfering with each recording head 152, and each recording head 152 is kept in a state where the accuracy of flattening is maintained. It can be attached to the carriage 50. In addition, since each recording head 152 is fixed to the sub-carriage 50 by fastening via the split pin 56, each recording head 152 is attached to the sub-carriage 50 without directly contacting each recording head 152 and the sub-carriage 50. Can be firmly attached.

  In addition, since the attachment portion 55 of the split pin 56 in the sub-carriage 50 is formed with a slit 55c for giving elasticity, it is possible to absorb the displacement in the vertical direction that occurs at the time of fastening. Each recording head 152 can be attached to the sub-carriage 50 in a state in which the sub-carriage 50 is prevented from interfering and the leveling accuracy is maintained. Further, since each recording head 152 is flattened by bringing a nozzle positioning glass plate into contact with each nozzle forming surface 152a, it is easy to align the nozzles formed on each nozzle forming surface 152a. It can be performed with high accuracy.

  The present invention is not limited to the case where a plurality of recording heads 152 are attached to the sub-carriage 50. For example, the same applies to the case where each component is attached to the attachment member so that a predetermined surface of the plurality of components is arranged on the same plane. Can be applied to. That is, each part and the mounting member are not brought into direct contact with each other, and a predetermined surface of each part is flattened, and each part is fixed to the mounting member in this state, thereby fixing each part to the mounting member. At this time, since the attachment member can be prevented from interfering with each component, each component can be attached to the attachment member while maintaining the flatness accuracy. Moreover, each component can be firmly attached to an attachment member, without making each component and an attachment member contact directly by fixing by fastening via an attachment member and a split pin.

  Any recording apparatus provided with a carriage can be applied to, for example, a facsimile apparatus, a copying apparatus, and the like. In addition to the recording apparatus, the meaning of a liquid ejecting apparatus that ejects a liquid corresponding to its use from a liquid ejecting head onto an ejected medium instead of ink and attaches the liquid to the ejected medium is, for example, a liquid crystal display or the like Color material jet head used for manufacturing color filters, electrode material (conductive paste) jet head used for electrode formation for organic EL display and surface emitting display (FED), bio-organic matter jet head used for biochip manufacturing, precision pipette The present invention can also be applied to an apparatus equipped with a sample ejection head or the like.
