  As shown in FIGS. 3 and 4, the carriage 50 includes a carriage body 51 and a cover 52. The carriage body 51 should form an ink cartridge storage chamber 51a (see FIGS. 6 and 7) that stores independent ink cartridges 35a to 35f (hereinafter collectively referred to as “ink cartridges 35”) for each of a plurality of colors. It is formed into a box-shaped body by a resin material. Bearing portions 51d and 51d through which the carriage guide shaft 34 (FIG. 2) passes are provided on the back side of the carriage body 51, and the rotation shafts 52b and 52b of the cover 52 are provided on the front side of the carriage body 51. Bearing portions 51b and 51b for supporting (FIG. 5) are formed.

  Each of the ink cartridges 35a to 35f housed in the ink cartridge housing chamber 51a is provided with an IC (not shown) that holds various information (ink color, ink remaining amount, etc.) relating to each ink cartridge. On the inner side wall of the cartridge housing chamber 51a, contacts 53a to 53e (hereinafter, collectively referred to as “contacts 53”) that are electrically connected to the ICs provided in the ink cartridges 35a to 35e are provided. (In FIG. 6, the contact corresponding to the ink cartridge 35f is provided at a position where it cannot be seen).

  The recording head 36 is provided at the bottom of the carriage body 51, and a flexible flat cable (hereinafter referred to as "FFC") 55 that connects the control unit of the printer (not shown) and the recording head 36 is shown in FIG. The inside of the carriage 51 is taken into the inside through a long hole 51 e formed in the side wall of the carriage body 51. Here, the long hole 51e is formed at a high position on the side wall of the carriage main body 51 as shown in the figure, so that the connection work between the FFC 55 and the recording head 36 can be easily performed.

  The cover 52 that covers the upper opening of the ink cartridge storage chamber 51 a has rotating shafts 52 b and 52 b (see FIG. 5), and the rotating shafts 52 b and 52 b are bearing portions 51 b and 51 b formed on the carriage body 51. By being pivotally supported on the carriage body 51, the carriage body 51 is provided so as to be rotatable. The distance (axis length) between the tips of the two rotating shafts 52b and 52b is formed to be larger than the interval between the bearing portions 51b and 51b, and the rotating shafts 52b and 52b once become the bearing portions 51b and 51b. The pivot shafts 52b and 52b are configured not to be easily detached from the bearing portions 51b and 51b.

  The cover 52 rotates to switch between a state (FIG. 3) covering the upper opening of the ink cartridge storage chamber 51a (FIG. 3) and a state opening (FIG. 4). Reference numeral 52d in the cover 52 denotes a latching hook. The latching hook 52d is latched on a latched portion 51f formed on the carriage main body 51 so that the closed state is maintained. ing.

  4, reference numeral 56 denotes a protrusion formed on the ink cartridge 35. When the cover 52 is closed, the pressing portion 52g formed on the cover 52 directs the protrusion 56 toward the bottom of the carriage 51 body. Energize. Thereby, the ink cartridge 35 is securely held in the ink cartridge storage chamber 51a, and in particular, the contact state between the IC provided in each ink cartridge 35 and the contact 53 (FIG. 6) is reliably maintained. It has become.

  As shown in FIG. 3, the cover 52 has an upper surface 52a formed smoothly by a flat continuous surface, and the back surface is formed in a state in which a plurality of ribs 52e and 52f are arranged in a lattice shape as shown in FIG. ing. Side walls 52c and 52c are formed in the vicinity of the rotating shafts 52b and 52b, and both side surfaces of the upper opening of the ink cartridge storage chamber 51a are covered by the side walls 52c and 52c. The cover 52 configured as described above is integrally formed of a resin material.

  The carriage 50 configured as described above is configured so that the cover 52 covers the upper opening of the ink cartridge storage chamber 51a without a gap, that is, no through hole is formed. It is possible to prevent the falling ink mist from entering the carriage 50. Furthermore, since the cover 52 covers the upper opening of the ink cartridge storage chamber 51a from both sides by the side walls 52c, 52c, the ink mist can be prevented from entering more reliably. Accordingly, the ink mist hardly adheres to the contact 53 arranged inside the ink cartridge storage chamber 51a, and information can be read from or written to the IC provided in each ink cartridge appropriately.

  Further, since the upper surface 52a of the cover 52 is formed by a flat continuous surface, it is possible to suppress turbulence of air around the carriage 50 when the carriage 50 reciprocates in the main scanning direction. As a result, the disturbance of the floating state of the ink mist can be suppressed, the ink mist can be prevented from being scattered over a wide range, and the ink mist is more difficult to enter the carriage 50.

  Furthermore, the cover 52 is formed so as to cover the upper opening of the ink cartridge storage chamber 51a without any gaps, and the back surface thereof is formed in a state in which a plurality of ribs 52e and 52f are arranged in a lattice shape. As a result, the rigidity of the ink cartridge storage chamber 51a can be urged more reliably toward the bottom of the ink cartridge storage chamber 51a, that is, the ink cartridge storage chamber 51a. The IC provided in each ink cartridge can always be surely brought into contact with the contact 53 arranged in the inside.

Next, another embodiment of the carriage 50 will be described with reference to FIGS. 8 to 11. FIGS. 8 and 9 are external perspective views of carriages 50A and 50B according to other embodiments, respectively, in which (A) shows a cover closed state and (B) shows a cover half-open state. 10 and 11 are external perspective views showing the shapes of covers 52C and 52D according to other embodiments.
A carriage 50A shown in FIG. 8 includes a carriage main body 51A and a cover 52A, and a carriage 50B shown in FIG. 9 includes a carriage main body 51B and a cover 52B.

  In the carriage main bodies 51A and 51B, an ink cartridge storage chamber (not shown) is formed in the interior of the carriage main body 51 in the same manner as the carriage main body 51. Similarly to the cover 52, the covers 52A and 52B are configured to cover the upper opening of the ink cartridge storage chamber (carriage main body) without a gap in the closed state, and are formed by a continuous surface having a flat upper surface. ing. Thereby, the same effect as the cover 52 can be obtained. The cover 52A has a rotation shaft (not shown) on the front side and is provided on the carriage body 51A so as to open toward the front side, and the cover 52B has a rotation shaft (not shown) on the rear side. The carriage body 51B is provided so as to open toward the rear side.

The feature of the covers 52A and 52B is that the upper opening of the ink cartridge housing chamber (carriage body) can be kept closed even in the half-open state.
More specifically, for example, FIG. 8B shows a state in which the cover 52A is half-opened, and in this half-opened state, the wall surface 52j formed around the cover 52A causes the ink cartridge storage chamber (carriage main body 51A). The closed state of the upper opening is maintained, so that it is possible to more reliably prevent the ink mist that floats and falls from entering the inside of the carriage. Similarly, the carriage 50B shown in FIG. 11 maintains the closed state of the upper opening of the ink cartridge storage chamber by the wall surface 52k formed on the cover 52B.

  Here, the state in which the cover 52A is half open means that the cover 52A is almost closed by its own weight and covers almost the upper part of the opening of the ink cartridge storage chamber (carriage body 51A), but is not completely closed. This means such a state where the carriage body 51A is not locked (the same applies to the cover 52B in FIG. 9). For example, in the case of the carriage 50 of FIG. 4, the latching hook 52d is not completely latched on the latched portion 51f, that is, the cover 52 is unlocked with respect to the carriage body 51, This is a state in which the cover 52 is stationary by its own weight while 52d rides on the upper portion of the hooked portion 51f.

  By the way, the cover 52 and the covers 52A and 52B are both configured to be able to interfere with the exterior case that forms the appearance of the printer 1 in a half-open state. For example, in FIG. 2, reference numeral 6 indicates a part of the outer case, and when the cover 52 is in a half-open state as indicated by reference numeral 52 ′, the cover 52 and the outer case 6 interfere with each other. Accordingly, this makes it possible for the user to easily recognize that the cover 52 is in the half-opened state, and to prevent recording from being executed while the cover 52 is in the half-opened state. (The same applies to the covers 52A and 52B in the state shown in FIGS. 8B and 9B).

Note that the covers 52A and 52B shown in FIGS. 8 and 9 can be configured like the covers 52C and 52D shown in FIGS. 10 and 11, respectively.
For example, the cover 52C in FIG. 10 is configured such that when closed, the upper edge 51g of the wall forming the ink cartridge storage chamber 51a is sandwiched from the outside and the inside by the wall portions 52m and 52n. Therefore, when closed, the ink mist can be more reliably prevented from entering the carriage body 51A. Similarly, the cover 52D of FIG. 11 is configured so that the upper edge 51g of the wall forming the ink cartridge storage chamber 51a is sandwiched from the outside and the inside by the wall portions 52m and 52n when the cover 52D is closed. Can more reliably prevent ink mist from entering the carriage main body 51B.

  The covers 52C and 52D are configured so that the upper opening of the ink cartridge storage chamber (carriage body) can be kept closed in the half-opened state, similarly to the covers 52A and 52B described above. In this state, it is configured to be able to interfere with the exterior case constituting the appearance of the printer 1, and it is possible to obtain the same effects as the covers 52A and 52B described above.
