1. Summary
The present invention relates to disposition embodiments of an ink tube that is connected to an external tank 60 in a recording apparatus 10. Hereinafter, disposition embodiments of an ink tube 50 will be described in sequence along with other embodiments. Additionally, in the following invention, although there are cases in which the description is given with an XYZ orthogonal coordinate system, among the coordinate system, a direction in which a carriage 41 moves (scans) is referred to as an X direction, a direction (vertical direction) in which is separated from the installation surface of the recording apparatus 10 is referred to as a Z direction and a direction (sub-scanning direction) which is orthogonal to the X direction and the Z direction is referred to as the Y direction.
(Disposition Embodiments of Ink Tube)
FIG. 1 is a perspective view of the recording apparatus 10 of the present invention. In addition, FIG. 2 is a schematic view that shows an outline of the main sections of the recording apparatus 10. The recording apparatus 10 is provided with a housing 20, a paper supply device 30, a carriage mechanism 40 and an ink tube 50. In addition, the recording apparatus 10 may be configured to have a configuration that is provided with an external tank 60 in addition to the abovementioned components, or may be configured to have a configuration that is not provided with an external tank 60. An aperture portion 21 (corresponds to a first aperture portion) is provided on the back surface side of the housing 20. The aperture portion 21 is a section in which a section of the back surface side of the housing 20 has been cut away, and in the present embodiment, the aperture portion 21 is formed so that the main scanning direction (the X direction) is longitudinal.
It is possible to supply the recording paper P from the paper supply device 30 inside the housing 20 through the aperture portion 21. The paper supply device 30 has a paper supply tray 31 and an isolation roller 32. The paper supply tray 31 is a section that carries the recording paper P and supports the recording paper P from the back surface side. The paper supply tray 31 may be configured from a single tray member 311 or may be configured from a plurality of tray members 311. In a case in which the paper supply tray 31 is configured from a plurality of tray members 311, the plurality of tray members 311 are provided to be capable of being drawn out or stowable depending on the size of the recording paper P. In the recording apparatus 10 shown in FIG. 1, a tray member 311 with two levels is displayed, but in the recording apparatus 10 of FIG. 1, there is a level of the tray member 311 that is hidden by the housing 20. Therefore, in the recording apparatus 10 of FIG. 1, the paper supply tray 31 is configured from a tray member 311 with a total of three levels. Considering this, among the three-levelled tray member 311, the lowest level of the tray member 311 corresponds to a first tray member, and a tray member 311 that extends from that tray member 311 (the first tray member) corresponds to a second tray member. In addition, even in a case of a two-levelled tray member 311, the lowest level of the tray member 311 corresponds to the first tray member and the tray member 311 that extends from that tray member 311 (the first tray member) corresponds to the second tray member. Additionally, the size of the tray member 311 is provided so as to gradually become smaller with movement toward the upstream side of the transport direction from the downstream side, and is provided such that a small tray member 311 is stowed in the internal space of a large tray member 311.
Additionally, in the recording apparatus 10 shown in FIG. 1, a wall-like fixed guide member 33a is provided in the tray member 311, and a protrusion 331 is provided at the lower side of this fixed guide member 33a. The protrusion 331 protrudes toward a direction that is separated from the tray member 311.
A guide member 33 is provided in the tray member 311 at the downstream side of the transport direction. The guide member 33 guides the position of the end portion of the width direction of the recording paper P, and is a member that prevents a situation in which the recording paper P is transported in a diagonal state or the like. A fixed guide member 33a and a movable guide member 33b are provided in the guide member 33. The fixed guide member 33a is provided in a fixed manner with respect to the tray member 311, and is provided so that positional movement in the main scanning direction (the X direction) is not possible. The movable guide member 33b is configured to be capable of movement along the main scanning direction (the X direction) using a sliding guide (not shown in the drawing) that is provided on the back surface side of a guide groove 34 and the tray member 311 in FIG. 2. As a result of this, the width between the pair of guide members 33 can be changed depending on the width of the recording paper P, and it is possible to feed the recording paper P to the side of the isolation roller 32 while preventing a situation in which the recording paper P becomes inclined.
Additionally, the isolation roller 32 is provided at an end portion of the downstream side provided in the transport direction of the paper supply tray 31. The isolation roller 32 is revolved by drive power being applied by a motor (not shown in the drawing), and it is possible to transport the recording paper P to the downstream side.
In addition, a carriage mechanism 40 that is provided with a carriage 41 is provided inside the housing 20. The carriage 41 is capable of moving in the main scanning direction (the X direction) along a carriage axis 42 due to the driving of a carriage motor (not shown in the drawing). Additionally, a recording head 43 is attached to a side of the carriage 41 that faces the transport path, ink is sprayed from the recording head 43, and it is possible to form a recording image of the recording paper P.
One end side of the ink tube 50 is attached to the carriage 41 through an adapter AP. The other end side of the ink tube 50 is connected to an external tank 60 that is on the outside of the housing 20. Further, it is possible to supply ink to the recording head 43 from the external tank 60 through the ink tube 50 and the adapter AP. Additionally, the carriage 41 includes a type that mounts an ink cartridge which is provided with memory. In this case, it is possible to provide a connection portion that reads the information of the memory, to the carriage 41, but it also possible to adopt a configuration in which an adapter AP is provided in a section (a connection portion on the side of the adapter), which is electrically connected to such a connection portion. In such a case, by performing transmission and reception of signals between the connection portion on the side of the adapter and the connection portion, it is possible to configure a state in which the recording head 43 operates normally.
Incidentally, the ink tube 50 that is connected between the carriage 41 and the external tank 60 is disposed in the following manner. In a case of proceeding from the carriage 41 along the ink tube 50, as shown in FIG. 2, after proceeding toward one side for a predetermined distance, the direction, in which the ink tube 50 that extends from the carriage 41 toward one side in the main scanning direction (the X direction), is reversed after passing the curved portion 501. As a result of this, proceeding along the ink tube 50 becomes proceeding toward the other side in the main scanning direction (the X direction). Further, proceeding for a predetermined distance reaches the turning portion 502 of the ink tube 50. The turning portion 502 is a section that turns the direction of the ink tube 50, and as specifically shown in FIG. 2, turns the direction of the ink tube 50 from a state in which the ink tube 50 proceeds along the main scanning direction (the X direction) to a state in which the ink tube 50 passes the aperture portion 21 and proceeds along the paper supply tray 31 (tray member 311).
Additionally, provided the direction of ink tube 50 is turned to proceed along the paper supply tray 31 (tray member 311), the length of the turning portion 502 is not limited.
In this case, as shown in FIG. 2, in the present embodiment, the ink tube 50 that has passed the turning portion 502 is positioned in a gap section S1 that is clamped between an inner wall portion 21a (corresponding to a wall surface portion) of the aperture portion 21 and a side surface portion of the movable guide member 33b, and is led to the outside of the housing 20 through the gap section S1. Further, after the ink tube 50 has proceeded along the paper supply tray 31 (tray member 311) for a predetermined distance, the ink tube 50 becomes separated from the paper supply tray 31 (tray member 311) and proceeds toward the external tank 60. In this manner, in the configuration shown in FIG. 2, the ink tube 50 reaches the gap section S1 after passing the turning portion 502 and is led to the outside of the housing 20 through the gap section S1. As a result of this, the ink tube 50 extends toward the upper side and the front side of the recording apparatus 10, and as a result of this extension, it is possible to prevent a situation in which a user is impeded from removing recording paper P that is stuck by putting their hand into the transport path when recording paper P is stuck in the transport path.
In addition, as shown in FIG. 1 and FIG. 2, in a case in which the ink tube 50 is led out to the outside of the housing 20, since a state in which the ink tube 50 passes through the aperture portion 21 of the housing 20 is attained, it is possible to prevent a situation in which the ink tube 50 is clamped in an opening and closing cover 70 (refer to FIG. 13; for example, a lid section, a scanning unit 12 (refer to FIG. 19) and the like correspond to the opening and closing cover 70) of the recording apparatus 10.
In addition, as shown in FIG. 3, the ink tube 50 has a configuration in which tube sections 51 which respectively conduct different types of ink, are lined up and joined. In the configuration shown in FIG. 3, a configuration in which the lined up plurality of tube sections 51 are unified, is used. However, a configuration in which the respective tube sections 51 are not joined and can move freely is also possible. In addition, in the recording apparatus 10 shown in FIG. 1 and FIG. 2, as shown in FIG. 3, the ink tube 50 is curved so that the vertical direction (the Z direction) is wide in addition to making a curve in a plane (an XY plane) formed by the main scanning direction (the X direction) and the sub-scanning direction (the Y direction). However, as shown in FIG. 4, the ink tube 50 may be curved so that the sub-scanning direction (the Y direction) is wide in addition to making a curve in a plane (an XZ plane) formed by the main scanning direction (the X direction) and the vertical direction (the Z direction). Further, in the ink tube 50, in addition to configuring the direction of the sequence of the tube sections 51 to be lined up in one direction in a cross-section of the tube sections 51, the direction of the sequence of the tube sections 51 may be configured to be lined up in a direction that is orthogonal to the direction in the cross-section.
In addition, in the configuration shown in FIG. 2, the ink tube 50 is positioned further on the front side than the carriage 41 in the sub-scanning direction (the Y direction) when moving toward the external tank 60 after passing the curved portion 501, and thereafter, is bent so as to move toward the gap section S1 after passing the turning portion 502. However, the ink tube 50 may be bent in the manner shown in FIG. 5. In the configuration shown in FIG. 5, the ink tube 50 is positioned on the back surface side of the carriage 41 without being positioned further on the front side than the carriage 41 when moving toward the external tank 60 after passing the curved portion 501, and thereafter, is bent so as to move toward the gap section S1 after passing the turning portion 502.
First Different Embodiment
Additionally, in the configuration shown in FIG. 1 and FIG. 2, a configuration in which the ink tube 50 is led out to the outside of the housing 20 by passing the gap section S1 that is clamped between an inner wall portion 21a of the aperture portion 21 and a side surface portion of the movable guide member 33b is described, but the configuration that leads the ink tube 50 out to the outside is not limited to the configuration shown in FIG. 1, FIG. 2 and FIG. 5. For example, as shown in FIG. 6, a configuration in which the ink tube 50 is led out to the external tank 60 by passing a gap section S2 that is clamped between an inner wall portion 21a of the aperture portion 21 and a side surface portion of the fixed guide member 33a is also possible. Even when the ink tube 50 is led out in this manner, it is possible to lead the ink tube 50 out to the outside of the housing 20 in a favorable manner. In addition, it is possible to prevent a situation in which a user is impeded from removing recording paper P that is stuck by putting their hand into the transport path when recording paper P is stuck in the transport path. Furthermore, in the same manner as the case of FIG. 1 and FIG. 2, it is possible to prevent a situation in which the ink tube 50 is clamped in an opening and closing cover 70 (refer to FIG. 13) of the recording apparatus 10.
Additionally, in a case in which the ink tube 50 is led out to the outside of the housing 20 by passing a gap section S2 such as that shown in FIG. 6, a configuration such as that shown in FIG. 7 may be adopted. In FIG. 7, the ink tube 50 is in a state of being hooked onto the protrusion 331, and after the hooking (abutting) onto the protrusion 331, the ink tube 50 extends toward the external tank 60. In a case in which such a configuration is adopted, it is possible to use the protrusion 331 for the positioning of the ink tube 50 when the ink tube 50 is led out to the outside of the housing 20. In addition, it is possible to change the direction in which the ink tube 50 is drawn out using the protrusion 331. However, as shown in FIG. 8, a configuration in which the ink tube 50 is led out to the outside of the housing 20 without being hooked onto the protrusion 331 may also be adopted. Naturally, even when a direction of leading the ink tube 50 out such as that shown in FIG. 8 is adopted, it is possible to lead the ink tube 50 out from the housing 20 in a favorable manner.
In addition, a configuration in which a notched portion S3 such as that shown in FIG. 9 is provided in the housing 20 in the vicinity of the gap section S2 is also possible. That is, in a case in which the gap section S2 is not sufficiently large or there is no leeway in the drawing out of the ink tube 50 from the inside of the housing 20, the recording apparatus 10 may be configured with a notched portion S3 such as that shown in FIG. 9 provided therein. Additionally, in FIG. 9, a configuration that is provided with the notched portion S3 in the gap section S2 is shown, but the notched portion S3 may be provided in a location other than the gap section S2. For example, the notched portion S3 may be provided in the gap section S1, the notched portion S3 may be provided in another area of the housing 20, or the notched portion S3 may be provided in the housing of the paper supply device 30 or the like as opposed to being provided in the housing 20.
Second Different Embodiment
In addition, a configuration such as that shown in FIG. 10 is also possible. In FIG. 10, the ink tube 50 has a configuration in which the ink tube 50 is led out to the outside of the housing 20 by passing the two gap sections S1 and S2. In this case, the two gap sections S1 and S2 indicate a gap section S1 that is surrounded by the inner wall portion 21a of the aperture portion 21 and a side surface portion of the movable guide member 33b, and a gap section S2 which is surrounded by the inner wall portion 21a of the aperture portion 21 and a side surface portion of the fixed guide member 33a. 
In order to lead the ink tube 50 out to the outside of the housing 20 from the two gap sections S1 and S2, it is necessary to branch the ink tube 50 in two. That is, there is an unbranched tube 50a, a first branched tube 50b and a second branched tube 50c in the ink tube 50. The unbranched tube 50a is a section of the ink tube 50, which is not branched, from the carriage 41 to a branched portion 52, the first branched tube 50b is a section of the ink tube 50 from the branched portion 52 that passes the gap section S1 and reaches the external tank 60, and the second branched tube 50c is a section of the ink tube 50 from the branched portion 52 that passes the gap section S2 and reaches the external tank 60.
Additionally, there may also be a section, which is adjacent to the branched portion 52, that greatly turns the direction of the branched tubes 50b and 50c in at least one of the first branched tube 50b and the second branched tube 50c. That is, in the configuration shown in FIG. 10, for example, there is a curving section 53 in the second branched tube 50c, which curves so as to greatly invert the direction of the second branched tube 50c after passing the branched portion 52 when moving toward the external tank 60 from the branched portion 52, but without being limited to the second branched tube 50c, there may be such a curving section 53 that inverts the direction in the first branched tube 50b and there may be such sections that curve so as to invert the direction in both the first branched tube 50b and the second branched tube 50c. 
Third Different Embodiment
Further, in the configuration shown in FIG. 11, in addition to there being a location (unbranched turning portion 54) that greatly turns the direction of the unbranched tube 50a in a front location that reaches the branched portion 52 in the unbranched tube 50a, there may be respective curving sections 53 that curve so as to turn the directions of the branched tubes 50b and 50c in the first branched tube 50b and the second branched tube 50c. The curving section 53 is a section that turns (curves) so that the directions in which the branched tubes 50b and 50c extend from the branched portion 52 respectively move toward both end sides in the main scanning direction (the X direction) between the abovementioned turning portion 502.
Fourth Different Embodiment
In addition, as shown in FIG. 12, a configuration in which there is a fixing member 55 that fixes a section of the ink tube 50 to a top panel 22 in a state in which the top panel 22 is exposed when the opening and closing cover 70 (refer to FIG. 13) is open may be used. However, it is necessary that this configuration does not impede the sliding of the carriage 41 when the carriage 41 slides along the carriage axis 42. Therefore, even when the carriage 41 is positioned at either end side of a scan in the main scanning direction (the X direction), the ink tube 50 is provided to be a predetermined amount longer than the length with which the longer side of either the fixing member 55 and one end side or the fixing member 55 and the other end side are linked. Additionally, in the configuration shown in FIG. 12, a section of the inside of the housing 20 that is not surrounded by the top panel 22 is an aperture section 23 (corresponding to the second aperture section).
In this case, in the configuration shown in FIG. 12, in a case in which the ink tube 50 is crushed by the ink tube 50 being clamped between the opening and closing cover 70 and the top panel 22 when the opening and closing cover 70 is closed, a configuration such as that shown in FIG. 13 may be used. In FIG. 13, a boss 24 is provided in any location of the housing 20. This boss 24 is a section that secures a gap that is greater than or equal to an amount that ensures that the ink tube 50 does not become crushed between the opening and closing cover 70 and the top panel 22 even in a case in which the opening and closing cover 70 is closed.
Fifth Different Embodiment
In addition, as shown in FIG. 14, there are cases in which the recording apparatus 10 is provided with a foreign matter receiving member 80 for preventing the ingress of foreign matter from the aperture portion 21. In the configuration shown in FIG. 14, a configuration in which the foreign matter receiving member 80 is received by the protrusion 331 (corresponding to an abutting portion) that is on at least one of the fixed guide member 33a or the movable guide member 33b, is adopted. As shown in FIG. 14, this protrusion 331 protrudes from at least one of the fixed guide member 33a and the movable guide member 33b, and in addition, protrudes toward a direction that is separated from the tray member 311. Therefore, in the state that is shown in FIG. 14, the protrusion 331 is provided so as to be positioned further on a front surface side than other sections of the fixed guide member 33a or the movable guide member 33b, and as a result of this, the protrusion 331 is capable of abutting against the foreign matter receiving member 80.
In such a configuration, in a case in which the paper supply tray 31 is configured by a plurality of tray members 311, there is a concern that the protrusion 331 will crush the ink tube 50 or sever the ink tube 50 when the tray members 311 are stowed. That is, the protrusion 331 is provided on a guide member 33 of the tray member 311 that is positioned lowest. Further, since the guide member 33 also reaches a state of being positioned on an upper side in a state in which the tray member 311 is drawn out, the gap sections S1 and S2 are relatively positioned on upper sides. Meanwhile, in a state in which the tray member 311 is drawn out, there are cases in which the ink tube 50 that is positioned further on the inside of the housing 20 than the gap sections S1 and S2 is in a state of being curved toward the centre of the housing 20 or the like so as to be positioned in a location in which the ink tube 50 is positioned when the tray member 311 is stowed. In such a state, if the lower tray member 311 is stowed in a stowing location, there is a concern that the ink tube 50 that is positioned in a stowing pathway (the lower side of the stowing pathway) of the guide member 33 will be severed or crushed 27 at the time of stowing.
In order to prevent the occurrence of such a situation, the foreign matter receiving member 80 and the protrusion 331 may be fixed with a fixing member 82. This fixing member 82 is a member that does not allow a change in the relative positions of the foreign matter receiving member 80 and the tray member 311 (the protrusion 331), and for example, it is possible to use bonding means or the like such as a tape member, an adhesive, a clipping member, wire.
In addition, in place of FIG. 14, a configuration such as that shown in FIG. 15 may be used. FIG. 15 is a view that shows a state in which the recording apparatus 10 is viewed from the back surface side, but as shown in FIG. 15, a stowing location and a tray member 311 may be fixed with a fixing member 83 so that a tray member 311 that is positioned lowest cannot be stowed in the stowing location. In such a case, the same member as that of the fixing member 82 may be used as the fixing member 83.
Sixth Different Embodiment
In addition, as shown in FIG. 16, a configuration in which the ink tube 50 is capable of being segmented may be used. That is, there are cases in which the handling of the ink tube 50 is troublesome if the ink tube 50 is long. In response to such cases, as shown in FIG. 16, the ink tube 50 may be configured to be capable of being segmented. In the configuration shown in FIG. 16, the respective segmented ink tube 50 can be joined via a coupling 90. However, since it is necessary that this coupling 90 pass through the abovementioned gap sections S1 and S2, it is necessary to form the coupling 90 to be small enough to be capable of passing through the gap sections S1 and S2. However, the coupling 90 itself may have a configuration which is connected to the respective segmented ink tube 50 at a later stage, and in such a case, the coupling 90 may be provided to be larger than the gap sections S1 and S2. In addition, a configuration in which the coupling 90 is provided for each tube section 51 is also possible, and in such a case, it is possible to make the coupling 90 smaller than the coupling 90 shown in FIG. 16.
Additionally, the abovementioned adapter AP may be attached to the end portion of the side opposite a side of the segmented ink tube 50 on which the coupling 90 is, and the external tank 60 may be connected to the end portion of the abovementioned side that is opposite the side on which the coupling 90 is. In addition, the connection structure of the coupling 90 may be any connection structure such as an interlocking method, a screwing method or the like, for example.
Seventh Different Embodiment
In addition, as shown in FIG. 17, a configuration in which a spacer 100 is provided between the movable guide member 33b and the inner wall portion 21a that faces the movable guide member 33b may be used. That is, in a case in which there is a concern that the gap section S1 will become narrow or the ink tube 50 will become crushed by the sliding of the movable guide member 33b, a spacer 100 such as that shown in FIG. 17 is provided. As a result of this, it is possible to prevent a situation in which the ink tube 50 is crushed.
Eighth Different Embodiment
In addition, as shown in FIG. 18, there are cases in which a pair of guide members 33 are movable guide members 33b. In a case in which guiding of the recording paper P is performed using a pair of movable guide members 33b, the movable guide members 33b both move so as to be symmetrical in the main scanning direction (the X direction), and as a result of this, recording paper P reaches a state in which the direction thereof is aligned by the centre of the placement surface of the paper supply tray 31 (so-called centre matching). In this kind of configuration, there are the two gap sections S1 shown in FIG. 1, but the ink tube 50 may be led out to the outside by passing at least one of these gap sections S1.
The abovementioned description is an outline of the present invention, but in cases in which the configurations related to the abovementioned FIGS. 1 to 18 can be combined, it is possible to configure a combined configuration as appropriate. For example, at least one of the disposition embodiment of the ink tube 50 in FIG. 3, the disposition embodiment of the ink tube 50 in FIG. 4, the embodiment of the ink tube 50 being hooked onto the protrusion 331 in FIG. 7, the embodiment of the ink tube 50 not being hooked onto the protrusion 331 in FIG. 8, the leading out of the ink tube 50 from the notched portion S3 in FIG. 9, the fixing member 55 in FIG. 12, the boss 24 in FIG. 13, the fixing member 82 in FIG. 14, the fixing member 83 in FIG. 15, the coupling 90 in FIG. 16 and the spacer 100 in FIG. 17 may be applied to the configurations related to the leading out of the ink tube 50 in FIG. 1, FIG. 2, FIG. 5, FIG. 6, FIG. 10, FIG. 11 or FIG. 16.
2. Specific Configuration of Recording Apparatus 10
Hereinafter, the specific configuration of the recording apparatus 10 will be described on the basis of FIG. 19 to FIG. 22. Additionally, a case in which the ink tube 50 passes a gap section S1 that is between the movable guide member 33b and the inner wall portion 21a and is led to the outside of the housing 20 in the manner already described on the basis of FIG. 1 and FIG. 2 will be described below.
However, naturally, the configuration related to the leading out of the ink tube 50 can be configured to be a configuration other than those of FIG. 1 and FIG. 2. In other words, in the recording apparatus 10 in FIG. 19 to FIG. 22, by adding changes as appropriate, it is possible to apply configurations related to the leading out of the ink tube 50 in FIG. 1, FIG. 2, FIG. 5, FIG. 6, FIG. 10, FIG. 11 or FIG. 18, and at such a time, at least one of the disposition embodiment of the ink tube 50 in FIG. 3, the disposition embodiment of the ink tube 50 in FIG. 4, the fixing member 55 in FIG. 12, the boss 24 in FIG. 13, the fixing member 82 in FIG. 14, the fixing member 83 in FIG. 15, the coupling 90 in FIG. 16 and the spacer 100 in FIG. 17 may be applied.
(2-1) Recording Apparatus 10 Provided with Scanning Unit 12

The paper supply tray 31 is configured such that a plurality (for example, 2, 3 or the like) of tray members 311 can be drawn out therefrom, and it is possible to support the recording paper P on the paper supply tray 31 by drawing out the tray members 311. In addition, as shown in FIG. 19, a foreign matter receiving member 80 is provided in the recording apparatus 10 in close proximity to the paper supply tray 31 (omitted from FIG. 19; refer to FIG. 14). In FIG. 19, in addition to the tray members 311 being stowed, the foreign matter receiving member 80 is positioned so as to make an aperture section for paper supply, which includes the abovementioned aperture portion 21, narrow (including a case in which the foregoing is blocked). Additionally, the foreign matter receiving member 80 is provided so as to be capable of rotating on an axis portion of both end sides of the main scanning direction (the X direction), and as a result of this, the foreign matter receiving member 80 can be switched between a case of being positioned in a position that narrows the aperture section in the abovementioned manner and a case of being positioned in a position that opens the aperture section.
In addition, as shown in FIG. 21, the paper supply device has an isolation roller 32 for supplying recording paper from the paper supply tray 31 (the tray members 311). The isolation roller 32 feeds the topmost recording paper P with which the isolation roller 32 is in contact to the downstream side by revolving while maintaining contact with the recording paper P that is in the paper supply tray 31 (tray member 311). Additionally, in the isolation roller 32, drive power is applied by a drive motor (not shown in the drawing) through a drive power transmission means (also not shown in the drawing), and as a result of this, the isolation roller 32 is driven in a revolving manner.
In addition, a paper supply roller 35a is provided further to the downstream side in the transport direction (the Y direction) than the isolation roller 32. The paper supply roller 35a faces a paper supply driven roller 35b and is capable of transporting recording paper P that is supplied from the isolation roller 32 to a facing location of the recording head 43 that is downstream in the transport direction (the Y direction). Drive power is applied to this paper supply roller 35a by a supply paper motor (not shown in the drawing). In addition, a platen 36 is provided further to the downstream side in the transport direction (the Y direction) than the paper supply roller 35a, and the platen 36 and the recording head 43 are provided so as to be capable of facing one another. In addition, a pair of paper output rollers 37 is provided further to the downstream side in the transport direction (the Y direction) than the platen 36. The pair of paper output rollers 37 is equipped with a paper output drive roller 37a and a paper output driven roller 37b. The paper output drive roller 37a is driven in a revolving manner by a motor (not shown in the drawing). In addition, the paper output driven roller 37b is pressed against the paper output drive roller 37a by a spring (not shown in the drawing).
In addition, the carriage mechanism 40 is provided with a carriage 41, a carriage axis 42, a recording head 43, a belt 44, a driven pulley 45, a gear pulley (omitted from the drawing) and a carriage motor (also omitted from the drawing). The carriage 41 is provided so that it is possible to attach the abovementioned adapter AP thereto. In addition, as shown in FIG. 21, the recording head 43 that is capable of spraying ink drops is provided on the bottom surface of the carriage 41.
In addition, the belt 44 is an endless belt, and a section thereof is fixed to the back surface of the carriage 41. This belt 44 is stretched in a tense state by the driven pulley 45 and the gear pulley.
In addition, in the configuration shown in FIG. 20 and FIG. 21, the ink tube 50 is attached to the front surface side (the downstream side of the transport direction of the recording paper P) of the carriage 41. However, the ink tube 50 may be attached to the upper surface side of the carriage 41, may be attached to the back surface side of the carriage 41 and may be attached to a side surface side of the carriage 41.
In the configuration shown in FIG. 20 and FIG. 21, the width direction of the ink tube 50 is disposed along a direction that is closer to the vertical direction (the Z direction) than the transport direction (the Y direction). Further, from the attachment position of the ink tube 50 to the carriage 41, the direction of the ink tube 50 is greatly changed so that the direction moves from one end side in the main scanning direction (the X direction) to the other end side with separation from the carriage 41 along the ink tube 50. Thereafter, the position of the ink tube 50 is shifted upward, and after that, the ink tube 50 is bent so as to move toward the back side, led to a gap section after passing through the top panel 22, and led out to the outside of the housing 20 by passing the gap section. Further, the ink tube 50 that has been led out to the outside is separated from a state in which the tube sections 51, inside which inks of the respective ink colors flow, are bundled together, and the tube sections 51 are connected to an external tank 60 in which the respective colors of ink are retained.
Additionally, the width direction of the ink tube 50 may be disposed along a direction that is closer to the transport direction (the Y direction) than the vertical direction (the Z direction).
In addition, the scanning unit 12 is provided so as to capable of opening and closing the printing unit 11 using a hinge section.

Further, as a result of the control of the control portion, the image sensor of the scanning carriage is moved relatively with respect to a target object for reading that is mounted on the copy holder by the carriage drive mechanism, and as a result of this, it is possible to read the target object for reading.
In the abovementioned manner, in a recording apparatus 10 such as that shown in FIG. 19 to FIG. 21, a configuration in which it is possible for the ink tube 50 to be led out to the outside of the housing 20 through the gap section S1 in a favorable manner, is used.
(2-2) Recording Apparatus 10 not Provided with Scanning Unit
FIG. 22 is a perspective view that shows a configuration of a recording apparatus 10 that is not provided with a scanning unit. This recording apparatus 10 is provided with a configuration that corresponds to the printing unit 11 of the abovementioned recording apparatus 10. Therefore, among the details of each location, the descriptions and display in the drawings of configurations that are common to both recording apparatuses will be omitted.
The recording apparatus 10 shown in FIG. 22 is provided with an opening and closing cover 70, and in a state in which this opening and closing cover 70 is open, it is possible to touch the carriage 41 and the ink tube 50 with one's hand.
In the configuration shown in FIG. 22, the ink tube 50 is attached to the upper surface of the carriage 41. However, the ink tube 50 may be attached to the front surface side (the downstream side of the transport direction of the recording paper P) of the carriage 41, may be attached to the back surface side of the carriage 41 and may be attached to a side surface side of the carriage 41.
The width direction of this ink tube 50 is disposed along a direction (including a case of being almost along the transport direction) that is closer to the transport direction (the Y direction) than the vertical direction. However, the width direction of the ink tube 50 may be disposed along a direction (including a case of being almost along the vertical direction) that is closer to the vertical direction (the Z direction) than the transport direction (the Y direction).
In the configuration shown in FIG. 22, from the attachment position of the ink tube 50 to the carriage 41, the direction of the ink tube 50 is greatly changed so that the direction moves from one end side in the main scanning direction (the X direction) to the other end side with separation from the carriage 41 along the ink tube 50. Thereafter, the position of the ink tube 50 is shifted upward, and after that, the ink tube 50 is bent so as to move toward the back side, led to a gap section S1 after passing through a frame plate 25 that supports the pulleys and the like, and led out to the outside of the housing 20 by passing the gap section S1. Further, the ink tube 50 that has been led out to the outside is separated from a state in which the tube sections 51, inside which inks of the respective ink colors flow, are bundled together, and the tube sections 51 are connected to an external tank 60 in which the respective colors of ink are retained.
In the abovementioned manner, in a recording apparatus 10 such as that shown in FIG. 22, a configuration in which it is possible for the ink tube 50 to be led out to the outside of the housing 20 through the gap section S1 in a favorable manner, is also used.
3. Advantageous Effects
According to the recording apparatuses 10 mentioned above, by passing the ink tube 50 through gap sections S1 and S2 between at least one guide member 33 and inner wall portions 21a that face at least one guide member 33, it is possible to lead the ink tube 50 to the outside of the housing 20. Therefore, it is possible for a user to easily put their hand into the recording apparatus 10 or the like from the aperture section 23 that is in the housing 20 when the opening and closing cover 70 is open, and it is possible to easily remove recording paper P that is stuck on the inside of the housing 20. That is, as a result of the application of the present invention, it is possible to improve the maintainability of the recording apparatus 10 without the ink tube 50 becoming an obstruction when removing recording paper P that has become stuck inside the housing 20.
In addition, in the recording apparatus 10 of the present invention, since the ink tube 50 is led to the outside of the housing 20 by passing at least one of the gap sections S1 and S2, it is possible to prevent a situation in which the ink tube 50 becomes crushed or the like by the opening and closing cover 70 or the like.
In addition, in the recording apparatus 10 of the present invention, as shown in FIG. 10 and FIG. 11, it is also possible to configure such that the ink tube 50 passes through both the gap section S1 and the gap section S2. In a case of configuring in this manner, it is also possible to improve the maintainability of the recording apparatus 10 without the ink tube 50 becoming an obstruction when removing recording paper P that has become stuck inside the housing 20. In addition, since the ink tube 50 is led to the outside of the housing 20 by passing both the gap section S1 and the gap section S2, it is possible to prevent a situation in which the ink tube 50 becomes crushed or the like by the opening and closing cover 70 or the like.
Furthermore, as shown in FIG. 14, in the recording apparatus 10 of the present invention, it is also possible to configure such that the foreign matter receiving member 80 and the protrusion 331 are fixed with the fixing member 82 so as to retain a state in which the foreign matter receiving member 80 abuts against the protrusion 331. In a case of configuring in this manner, it is possible to prevent stowing of the tray member 311 in the stowing location, and it is possible to prevent a situation in which the protrusion 331 severs or crushes the ink tube 50 that is positioned in the stowing pathway (the downstream side of the stowing pathway) of the guide member 33 when the tray member 311 is stowed. Additionally, in place of the fixing member 82 shown in FIG. 14, the fixing member 83 such as that shown in FIG. 15 may be used. In a case of configuring in this manner, it is also possible to prevent a situation in which the protrusion 331 severs or crushes the ink tube 50 when the tray member 311 is stowed.
In addition, as shown in FIG. 17, in the recording apparatus 10 of the present invention, it is also possible to configure so as to provide a spacer 100 between the movable guide member 33b and the inner wall portion 21a. In a case of configuring in this manner, it is even possible to prevent a situation in which the ink tube 50 becomes crushed by the movable guide member 33b in a case in which the movable guide member 33b is moved toward the inner wall portion 21a. 
In addition, in the recording apparatus 10 of the present invention, the ink tube 50 passes through the aperture section 23 (refer to FIG. 12) and is positioned on the top panel 22 after jutting out from the inside of the housing 20, and thereafter, the ink tube 50 is configured to be able to pass through the gap sections S1 and S2. In a case of configuring in this manner, since a section of the ink tube 50 is positioned on the top panel 22, the ink tube 50 is supported by the top panel 22. As a result of this, it is possible to prevent the ink tube 50 from reaching a scanning pathway of the carriage 41 and becoming an obstacle to the scanning of the carriage 41.
Furthermore, as shown in FIG. 12, in the recording apparatus 10 of the present invention, it is also possible to configure such that a section of the ink tube 50 is fixed to the top panel 22 by the fixing member 55. In a case of configuring in this manner, it is possible to prevent a situation in which the ink tube 50 is shaken at the time of the scanning of the carriage 41, and it is possible to stabilize the behavior of the ink tube 50 inside the housing 20.
4. Modification Examples
One embodiment of the present invention has been described above, but it is possible to make various modifications to the present invention. Such modification will be described below.
(4-1) First Modification Example
In the abovementioned embodiment, the ink tube 50 is connected to the carriage 41 through an adapter AP. However, it is possible to adopt a configuration in which the ink tube 50 is connected to the carriage 41 without the adapter AP. For example, in a configuration in which a sub tank in which ink is retained, is provided instead of an ink cartridge being mounted on the carriage 41, a configuration in which the ink tube 50 is connected in a state of being capable of conducting ink to the sub tank.
(4-2) Second Modification Example
In addition, in the abovementioned embodiment (this includes the different embodiments and the like and the same applies below), the gap sections S1 and S2 are configured to be between the inner wall portion 21a of the aperture portion 21 of the housing 20 and the guide member 33. However, the gap sections S1 and S2 may be configured to be in sections other than these. For example, the paper supply device 30 may be positioned in the aperture portion 21 and the gap sections S1 and S2 may be configured to be between the inner wall portion of the housing section of the paper supply device 30 and the guide member 33. In a case of configuring in this manner, it is also possible to improve the maintainability of the recording apparatus 10 without the ink tube 50 becoming an obstruction when removing recording paper P that has become stuck inside the housing 20. In addition, since the ink tube 50 is led to the outside of the housing 20 by passing both the gap section S1 and the gap section S2, it is possible to prevent a situation in which the ink tube 50 becomes crushed or the like by the opening and closing cover 70 or the like.
(4-3) Third Modification Example
In addition, in the abovementioned embodiment, at least one of the gap section S1 and the gap section S2 is configured to be between the inner wall portion 21a of the aperture portion 21 of the housing 20 and the guide member 33. However, at least one of the gap section S1 and the gap section S2 may be between the inner wall portion 21a of the aperture portion 21 of the housing 20 and the tray member 311 (in particular, the wall portion that is positioned at the end portion of the tray member 311). That is, regardless of whether or not there is a guide member 33, a section that is between the inner wall portion 21a and the tray member 311 may be configured to be the gap sections S1 and S2. In a case of configuring in this manner, it is also possible to lead the ink tube 50 out to the outside of the housing 20 in a favorable manner using at least one of the gap section S1 and the gap section S2. Additionally, in this case, it is particularly preferable to lead the ink tube 50 out to the outside of the housing 20 in a favorable manner using at least one of the abovementioned gap section S1 and the gap section S2 between the tray member 311 that corresponds to a second tray member and the inner wall portion 21a. 
(4-4) Fourth Modification Example
In addition, in a case (the case of the Third Modification Example) in which the ink tube 50 is led out to the outside of the housing 20 using a gap section (at least one of the gap section S1 and the gap section S2) between the inner wall portion 21a of the aperture portion 21 of the housing 20 and the tray member 311 (in particular, a wall portion that is positioned at the end portion of the tray member 311) in the manner described above, a wall portion of the tray member 311 may be configured to function as a guide member 33.
(4-5) Fifth Modification Example
In addition, in the abovementioned embodiment, as shown in FIG. 7, the ink tube 50 is in a state of being hooked onto the protrusion 331, and after the hooking (abutting) onto the protrusion 331, the ink tube 50 extends toward the external tank 60. However, the following configuration may be used. That is, in the cases of the Third Modification Example and the Fourth Modification Example, the protrusion 331 is provided in wall portion side of the tray member 311. Further, in a case in which the ink tube 50 is led out to the outside of the housing 20 using a gap section (at least one of the gap section S1 and the gap section S2) between the inner wall portion 21a of the aperture portion 21 of the housing 20 and the tray member 311 (in particular, a wall portion that is positioned at the end portion of the tray member 311), the ink tube 50 may be configured to hook onto the abovementioned protrusion 331, and extend toward the external tank 60 after the hooking (abutting) onto the protrusion 331. In this case, a configuration in which there is a protrusion 331 even if there is not a guide member 33 on the tray member 311 is used (naturally, it is also possible for there to be a guide member 33 on the tray member 311), but in this kind of configuration, it is also possible to use the protrusion 331 for the positioning of the ink tube 50. In addition, it is possible to change the direction in which the ink tube 50 is drawn out using the protrusion 331.
(4-6) Sixth Modification Example
