The carriage 1 is formed with a plurality of cartridge storage portions 7 for storing ink cartridges 5. In this specification, the side facing diagonally left front in FIG. 1 is the front side of the carriage 1 and the opposite side is the rear side of the carriage 1. Regarding the other members attached to the carriage 1, the words on the front side and the rear side are used in the same manner as the carriage 1 according to the orientation when attached to the carriage 1. In particular, the front and rear of the connector holder attached in the carriage are the same as the front and rear of the carriage.

  A circuit board 9 (see FIGS. 2A and 2B) is provided on the back side of the carriage 1, and a conductive connection portion 12 is formed on the circuit board 9. A connector 11 is provided on the back side of the inner surface of the carriage 1 so as to correspond to each cartridge housing portion 7. Each connector 11 is held by a connector holder 13 (see FIG. 9). Further, as shown in FIG. 3, both end portions 14 of the connector holder 13 are held by being slidably fitted into the groove portions 16 in the carriage 1. In this holding state, the connector holder 13 is positioned on the outer base portion 46 in the carriage 1. That is, the recording head unit 2 and the connector holder 13 are configured so as to overlap each other in the assembling direction, and the size of the carriage 1 in the depth direction can be reduced.

  In this specification, a connector holder unit 74 is defined by attaching all the connectors 11 and the circuit board 9 to the connector holder 13 in advance. In this embodiment, the connector holder 13 is formed separately from the carriage, and all the connectors 11 and the circuit board 9 are attached to the connector holder 13 in advance before being attached to the carriage 1.

  Further, the inner bottom portion of the carriage 1 is constituted by the head base 40 of the recording head unit 2, and ink supply ports 6 are formed in this portion so as to correspond to the respective cartridge storage portions 7. 6 is partitioned by a protruding wall portion 8, and the inside of the partitioned portion is a positioning portion 18 for positioning the ink cartridge 5.

Further, the wall 8 on the side of the connector holder 13, that is, the wall opposite to the positioning portion 18, is formed as the contact portion 24.

  As shown in FIG. 5, each ink cartridge 5 has a cartridge side substrate 15 formed on the surface facing the connector 11, and a lock lever 17 for fixing the ink cartridge 5 to the carriage 1 above the substrate. (See FIG. 1). Further, the conductive connection portion 10 (see FIG. 5 and the like) is formed on the cartridge side substrate 15. When the ink cartridge 5 is pushed into the cartridge housing portion 7, the lock lever 17 is temporarily elastically deformed slightly, so that the ink cartridge 5 is fixed in the cartridge housing portion 7 in a snap manner.

  Next, as shown in FIG. 6, the connector 11 has a first surface 19 facing the cartridge side substrate 15 and a second surface 21 facing the circuit board 9 provided on the back side of the carriage 1. It has a function of interposing between the board 15 and the circuit board 9 to provide electrical continuity between them. The connector 11 has nine metal contacts 25 arranged in parallel to each other as an example with respect to a housing 23 made of a known material. The nine contacts 25 are arranged in two rows so that every other contact is in the same position in a side view, and the adjacent contacts 25 are arranged with their positions shifted in the longitudinal direction of the housing 23, and arranged in a staggered manner as a whole. Has been.

  Each contact 25 has the same shape. Each contact 25 mainly includes a first contact arm 29 extending from the base end portion 27 toward the first surface 19 and a second contact arm 31 extending toward the second surface 21 and shorter than the first contact arm 29. The contact arms 33 and 35 having substantially semicircular shapes are formed at the tips of the connection arms 29 and 31. The second contact arm 31 is shorter than the first contact arm 29. The contact 25 is supported by the housing 23 by press-fitting a base end portion 27 of the contact 25 into a thin plate portion 37 formed in the housing 23.

  The contact terminal 33 of the first contact arm 29 and the contact terminal 35 of the second contact arm 31 protrude from the first surface 19 and the second surface 21, respectively, and the first contact arm is loaded when a load is applied to the contact terminals 33 and 35. 29 and the second contact arm 31 are bent inward in a leaf spring shape. Due to such a spring action, the contact terminals 33 and 35 can be brought into pressure contact with the conductive connection part 10 of the cartridge side substrate 15 and the conductive connection part 12 of the circuit board 9 respectively, thereby realizing a reliable electrical connection. can do.

  As shown in FIG. 5, supported portions 38 are formed on both side surfaces of the connector 11 so as to extend in a convex shape in the vertical direction. Further, groove-shaped support portions 46 are formed at both ends of each region in the connector holder 13 where the connectors 11 are stored. The connector 11 is attached to the connector holder 13 by being pushed in from above so that the supported portion 38 of the connector 11 is guided by the support portion 46 of the connector holder 13.

  As shown in FIG. 8, the circuit board 9 is held by holding ribs 39 on the back side of the connector holder 13. When the connector holder 13 is set in the carriage 1, as shown in FIG. 7 (the connector holder 13 is omitted for easy understanding), the four rib-shaped portions formed in the carriage 1 are formed. The back surface contact portion 41 abuts against the back side of the circuit board 9 to prevent the circuit board 9 from being deformed so as to bend rearward. This is because, as described above, when the contact terminals 33 and 35 are in pressure contact with the conductive connection portion 10 of the cartridge side substrate 15 and the conductive connection portion 12 of the circuit board 9, respectively, the force that the circuit board 9 bends outward is generated. This is because the circuit board 9 is restrained from bending to maintain a reliable electrical connection.

  As shown in FIG. 9, a deformation prevention pad 43 is formed on the front side of the connector holder 13, that is, on the bottom on the side where the ink cartridge 5 is located. The deformation prevention degree abutting portion 43 is provided as a convex portion near the center of the connector holder 13, has a substantially trapezoidal shape, and the side on the short side of the trapezoid is an abutment surface 45. As shown in FIG. 4, when the connector holder 13 is set in the carriage 1, the degree of deformation prevention is such that the contact surface 45 comes into contact with the contact portion 24 formed on the connector holder 13 side of the wall portion 8. The dimensions of the abutment 43 are set.

  Thus, when the connector holder unit 74 is set in the carriage 1, the deformation prevention degree contact 43 comes into contact with the covered portion 24 provided in the carriage 1. However, the ink cartridge 5 does not bend toward the ink cartridge 5 side, and the initial shape can be maintained, and a good contact state between the contact terminals 33 and 35 and the conductive connection portions 10 and 12 can be maintained.

  In this embodiment, the connector 11 and the circuit board 9 are attached to the connector holder 13 in advance to form the connector holder unit 74 separately from the carriage 1, and this connector holder unit 74 is attached to the carriage 1 later. It is configured as follows. By forming the connector holder unit 74 in this way in advance, it is not necessary to slide the circuit board 9 onto the connector holder 13 and assemble it, so that problems such as chipping of the register do not occur. Further, the assembly work can be performed more easily than attaching the connector 11 and the circuit board 9 to the connector holder 13 after the connector holder 13 is attached to the carriage 1.

  In order to attach the circuit board 9 to the connector holder 13 in the process of creating the connector holder unit 74, for example, a method shown in FIG. In the method shown in FIG. 10, a flexible hook 53 is formed on the connector holder 13 as shown in FIG. 10A, while the flexible hook 53 is located at a position corresponding to the flexible hook 53 on the circuit board 9 side. A locked portion (not shown) for locking 53 is formed. First, as shown in FIG. 10B, the upper side 47 of the circuit board 9 is fixed in the reverse concave positioning portion 49 of the connector holder 13, and then the fixed upper side 47 is shown in FIG. 10C. The circuit board 9 is rotated around the center to bring the lower side 51 closer to the connector holder 13 side. When the conductive connecting portion 12 of the circuit board comes into contact with the contact terminal 35, the circuit board 9 moves to the rear side with the contact terminal 35 as a fulcrum, as shown in FIG. As shown in FIG. 10 (e), the lower end 51 side of the circuit board 9 is finally fixed by the front end locking portion 54 of the flexible hook 53 being locked to the locked portion, and the upper side 47 side is reverse concave. The positioning portion 49 is fixed to the rear side.

  As shown in FIG. 10 (e), when the circuit board 9 is attached to the connector holder 13, the upper side 47 of the circuit board 9 is within the range of the clearance 58 formed in the reverse concave positioning portion 49, and the arrow 63. The connector holder can be moved slightly in the front-rear direction as shown in FIG. Further, the lower side 51 side of the circuit board 9 is also in a state where the front end locking portion 54 of the flexible hook 53 is locked to the locked portion (FIG. 10E), and the lower side 51 side is subjected to the elastic force of the contact terminal 35. In contrast, it can move between the state where it is pushed forward (FIG. 10D). Therefore, the circuit board 9 is attached in a slightly movable state in the front-rear direction of the connector holder 13.

  11 and 12, the housing 23 is located between the support portion 46 of the connector holder 13 (see FIG. 5) and the supported portion 38 of the housing 23 of the connector 11 (see FIG. 5). A clearance 62 is formed so as to be slightly movable in the front-rear direction with respect to 13. In the present invention, only the housing 23 of the connector 11 is slightly movable in the front-rear direction of the connector holder 13, and the circuit board 9 is not necessarily movable with respect to the connector holder 13.

  According to this embodiment, a clearance 62 is formed between the support portion 46 of the connector holder 13 and the supported portion 38 of the housing 23 so that the housing 23 can move with respect to the connector holder unit 74. Therefore, the housing 23 can move slightly with respect to the connector holder unit 74. As a result, even if the connector holder 13 is bent and deformed for some reason in the carriage 1, the clearance 62 absorbs the deformation and the contact terminals 33 and 35 on the connector 11 side and the conductive connection portions 10 and / or of the ink cartridge 5 are used. Alternatively, it is possible to avoid affecting the contact state of the circuit board 9 with the conductive connection portion 12.

  That is, in the state where the connector unit 74 in which the connector 11 and the circuit board 9 are mounted on the connector holder 13 is attached to the carriage 1, the contact terminals 33 and 35 of the connector 11 are connected to the conductive connection portion 10 of the ink cartridge 5. And the conductive connection portion 12 of the circuit board 9 are elastically contacted to realize electrical continuity between the circuit board 9 and the ink cartridge 5.

  If this elastic contact state has been reached, the contact terminals 33 and 35 of the connector 11, the conductive connection portion 10 of the ink cartridge 5 and the conductive connection portion 12 of the circuit board 9 are mutually connected by the elastic force. Since the position is maintained in a state where the contact pressure is balanced, in this state, it is more convenient in optimizing the balance that the connector 11 is not constrained by the connector holder 13. The present invention realizes the convenient structure by the clearance 62, and the connector 11 has a degree of freedom without being constrained by the clearance 62, so that the balance of the contact pressure of each contact portion is improved. Moreover, even if the connector holder 13 is deformed for some reason, it can be prevented from being affected.

Also,
By mounting the circuit board 9 and the connector 11 in the connector holder 13 in advance in the form of the connector holder unit 4 before being attached to the carriage 1, the following effects can be obtained. In some cases, it takes a long time to store the connector holder unit 4 in the form of the connector holder unit 4 and to attach it to the carriage 1. The connector holder 13 may bend and deform by acting on the holder 13. As a result, the deformed connector holder unit 4 may not be assembled to the carriage 1 in some cases. According to the present embodiment, the clearance 62 can reduce the influence of the urging force on the connector holder 13 due to the spring force of the contact 25, and the connector holder 13 can be prevented from being bent and deformed in the front-rear direction.

  In the above embodiment, the circuit board 9 and the connector 11 are both movable in the front-rear direction of the connector holder 13. However, the circuit board 9 and the connector 11 are movable in the vertical direction in FIG. There may be. By diversifying the movable directionality of the circuit board 9 and the connector 11 in this way, the connector holder 13 can be prevented from being bent and deformed in various directions other than the front-rear direction.

  Furthermore, although the above embodiment has been described by taking an ink jet printer as an example of a recording apparatus, a liquid corresponding to the application is ejected from a liquid ejecting head corresponding to a recording head to a liquid ejecting material corresponding to a recording material instead of ink. Thus, the present invention can be similarly applied to a liquid ejecting apparatus that attaches a liquid to a liquid ejecting material.
