## Background
BACKGROUND
1. Technical Field
The present invention relates to a recording apparatus which performs recording on a recording medium.
2. Related Art
In an ink jet printer, which is an example of a recording apparatus, there is a case in which the control section and the recording head of the printer are connected to each other through a flexible flat cable as disclosed in JP-A-2008-80614.
In addition, the ink jet printer includes a serial type and a line head type. In a line head type printer, the recording head is configured such that ink discharge nozzles are arranged to cover the whole area of a paper width, an ink accommodation section is connected to the recording head through an ink tube, and thus ink is supplied from the ink accommodation section to the recording head. That is, a state in which a plurality of flexible flat cables and a plurality of ink tubes extend from the recording head.
There are cases in which the line head type ink jet printer is easily increased in size and the maintenance, exchange or the like is performed on a recording head by a serviceman for a printer installation spot. At this time, there is a problem in that the removal of the flexible flat cables is complicated, it requires extra effort to perform the work, and thus long time work is forced.
More specifically, for example, all of the flexible flat cables which extend from the recording head are connected to a control substrate. However, the control substrate is generally provided in the secluded location of the device, and thus accessibility is not good. Accordingly, when it is necessary to exchange the flexible flat cables for some reasons, for example, when a contact part, which is connected to the recording head, is deteriorated or damaged, it is necessary for the serviceman to access the control substrate and to exchange the flexible flat cables, with the result that it requires extra effort to perform the work, and thus long time work is forced. In addition, as disclosed in JP-A-2009-132036, all of the ink tubes are connected to a cartridge holder which is separated from the recording head, and thus there is the same problem as in the work which is performed on the flexible flat cable when the ink tubes are exchanged.

Outline of Printer
An ink jet printer 10 (hereinafter, referred to as a printer 10) will be described as an example of a liquid discharge device with reference to FIG. 1. The printer 10 is configured as a multifunction printer which includes a device main body 12 and a scanner unit 14. The device main body 12 includes a plurality of paper accommodation cassettes 16 which accommodate paper P (refer to FIG. 2) as a “recording medium”. Each of the paper accommodation cassettes 16 is attached to be detachable from the front surface side of the device main body 12 (−X axis direction side in FIG. 1). Also, in the specification, the paper P indicates regular paper, thick paper, photograph paper, or the like as an example.
In addition, in the device height direction (Z axis direction) of the device main body 12, a paper receiving tray 20, which receives the paper P on which recording is performed by a line head 18 that will be described later, is provided between the scanner unit 14 and the paper accommodation cassette 16.
Paper Transport Path
Subsequently, a transport path of the paper P in the printer 10 will be described with reference to FIG. 2. Also, in FIG. 2, reference symbols are attached to only the main components of the transport path of the paper P, and the reference symbols are not attached to the other components, particularly, spurs which are provided in plural.
The printer 10 in the embodiment includes a paper transport path 22. The paper transport path 22 includes a straight path 24, a switchback path 26, a reverse path 28, a facedown ejection path 30, and a feed path 32 which is connected to the straight path 24 from the paper accommodation cassette 16.
In the feed path 32, a feeding roller 34, a pair of separating rollers 36, and a pair of transport rollers 38 are sequentially provided along the transport direction of the paper P. The feeding roller 34 is rotationally driven by a driving motor which is not shown in the drawing. The pair of separating rollers 36 separates the paper P by nipping the paper P. The pair of transport rollers 38 includes one roller as a driving roller which is rotationally driven by a driving motor which is not shown in the drawing, and the other roller as a follower roller.
Also, in the description below, description will be performed while it is assumed that each of the pairs of transport rollers in the specification includes one roller which is rotationally driven by a driving motor which is not shown in the drawing, and the other roller as a follower roller.
The paper P, which is accommodated in the paper accommodation cassette 16, is fed to the downstream side of the feed path 32 by the feeding roller 34. The paper P which is fed by the feeding roller 34 is sequentially nipped by the pair of separating rollers 36 and the pair of transport rollers 38, and is fed toward the downstream side of the feed path 32. In addition, a pair of transport rollers 40 is provided on the downstream side of the transport direction of the pair of transport rollers 38.
In the embodiment, the feed path 32 and the straight path 24 are connected to each other in the location of the pair of transport rollers 40. That is, the feed path 32 is set as a path from the paper accommodation cassette 16 to the pair of transport rollers 40.
The straight path 24 is configured as a path which linearly extends. The pair of transport rollers 40, a belt transport part 42, the line head 18 as a “recording section”, and a first flap 44 are sequentially provided in the straight path 24 along the transport direction. Also, in the embodiment, the straight path 24 is set as a path from the pair of transport rollers 40 to the first flap 44. That is, the straight path 24 is set as a path which passes through the line head 18 and extends to the upstream side and the downstream side of the line head 18.
In the embodiment, the line head 18 includes a plurality of nozzle heads 19. In the embodiment, the line head 18 is configured to perform recording by discharging ink from a plurality of nozzles, which are provided in the nozzle heads 19, to the recording surface of the paper P when the paper P is transported in an area which faces the nozzle heads 19. The line head 18 according to the embodiment is, for example, a recording head which is provided such that nozzles for discharging ink are arranged to cover the whole area in a paper width direction, and is configured as the recording head which is capable of performing recording in the whole area of the paper width without moving in the paper width direction.
In addition, the belt transport part 42 is arranged in an area which faces the nozzle heads 19 of the line head 18. The belt transport part 42 transports the paper P on the downstream side of the transport direction by driving a belt. At this time, the belt transport part 42 supports a side opposite to the recording surface of the paper P. Further, the recording surface of the paper P, which is supported by the belt transport part 42, faces the nozzle heads 19, and recording is performed on the recording surface of the paper P in such a way that ink is discharged from the nozzles of the nozzle heads 19 of the line head 18. In addition, the belt transport part 42 defines the distance (gap) between the recording surface of the paper P and the head surfaces of the nozzle heads 19 by supporting the paper P from below.
Subsequently, the first flap 44 is located on the downstream side of the transport direction of the line head 18. The first flap 44 is configured to be capable of oscillating through a driving mechanism in which a control section 90 (refer to FIG. 11), which will be described later, performs control. The first flap 44 is configured to be capable of switching between a posture (state in FIG. 2) which connects the straight path 24 to the switchback path 26 and a posture (not shown in the drawing) which connects the straight path 24 to the facedown ejection path 30. Also, a driving mechanism in which the first flap 44 is driven in the embodiment is configured with solenoid. In addition, an operation of switching between the postures of the first flap 44 is controlled by the control section 90 (refer to FIG. 11).
When the first flap 44 has the posture (not shown in the drawing) which connects the straight path 24 to the facedown ejection path 30, the paper P is sent to the facedown ejection path 30 from the straight path 24 by the belt transport part 42.
The facedown ejection path 30 is curved and reversed while extending from the straight path 24 to the upper side in the device height direction. Further, in the facedown ejection path 30, a plurality of pairs of transport rollers 46 is provided in the transport direction at appropriate intervals.
The facedown ejection path 30 includes a path up to an outlet 48 which is located in the downstream side of the transport direction of the pairs of transport rollers 46 which are located on the most downstream side of the transport direction from the first flap 44. That is, the facedown ejection path 30 is a transport path which is connected to the straight path 24, and is a path which causes the paper P that is passed through the line head 18 to be curved, reversed, and ejected.
The paper P, in which recording is performed on the recording surface by the line head 18, is sequentially nipped by the pairs of transport rollers 46 which are sequentially provided from the first flap 44 along the transport direction in the facedown ejection path 30. Further, the paper P is ejected toward the paper receiving tray 20 from the outlet 48.
Here, when the paper P is transported through the facedown ejection path 30, the paper P is transported while a recording surface which is recorded last by the line head 18 to face upward is subsequently transported while the recording surface is caused to be curved toward the inside of the curved part of the facedown ejection path 30, and then is ejected toward the paper receiving tray 20 from the outlet 48 while the recording surface is caused to face downward.
Paper Transport Path in Double-Sided Recording
When the first flap 44 has a posture (refer to FIG. 2) which connects the straight path 24 to the switchback path 26, the paper P is sent to switchback path 26 from the straight path 24 by the belt transport part 42.
The switchback path 26 and the reverse path 28 are paths through which the paper P passes when recording is performed on a second surface after recording is performed on the first surface of the paper P, that is, when double-sided recording is performed. Also, when recording is not performed on the first surface and recording is performed on the second surface, the paper P passes through the switchback path 26 and the reverse path 28 in the same manner. That is, in the specification, the double-sided recording means recording performed on the second surface by reversing the paper P regardless of whether or not recording is performed on the first surface.
The switchback path 26 is located inside the facedown ejection path 30 which is curved and reversed while facing upward in the device height direction, and extends along the facedown ejection path 30. Further, the switchback path 26 includes a pair of transport rollers 50.
In addition, in the embodiment, the switchback path 26 is set as a path from a second flap 52, which is provided on upper side of the first flap 44, to an opening 54 which is provided at the tip of the switchback path 26. When the switchback path 26 is connected to the straight path 24 by the first flap 44 (refer to FIG. 2), the paper P is sent from an area, which faces the line head 18, to the switchback path 26 through first flap 44 by the belt transport part 42. The paper P is sent to a location in which the rear end of the switchback path 26 in the transport direction is nipped by the pair of transport rollers 50.
Also, here, the second flap 52 will be described. The second flap 52 is provided on the upper side of the first flap 44 in the device height direction (Z axis direction). Further, the second flap 52 is interlocked with the operation of the first flap 44 and is oscillated by an interlocking mechanism which is not shown in the drawing. That is, the second flap 52 is controlled by the control section 90 through the first flap 44 and the interlocking mechanism.
The second flap 52 has a posture which connects the switchback path 26 to the reverse path 28 in a state (refer to FIG. 2) in which the first flap 44 connects the straight path 24 to the switchback path 26. On the other hand, the second flap 52 has a posture which connects the switchback path 26 to the reverse path 28 in a state in which the first flap 44 connects the straight path 24 to the facedown ejection path 30.
When the second flap 52 has a posture which connects the switchback path 26 to the reverse path 28, the control section 90 rotates the pair of transport rollers 50 in a direction inverse to the direction in which the paper P is sent to the switchback path 26, and sends the paper P to the reverse path 28 while causing the rear end side of the paper P to be the tip end side. That is, the paper P is switched back.
The reverse path 28 is set as a path which passes through the upper side of the line head 18 from the second flap 52 and reaches the pair of transport rollers 40 of the straight path 24. The plurality of pairs of transport rollers 56 is provided in the transport direction at appropriate intervals in the reverse path 28.
The outlet side of the reverse path 28 is configured to join to the straight path 24 in the upstream location of the pair of transport rollers 40 in the straight path 24. Further, the paper P is sent to the straight path 24 again. That is, the reverse path 28 is a transport path which is connected to the switchback path 26, and is set as a path that reverses the paper P, which is transported in the inverse direction, that is, which is switched back, by causing the upper side of the line head 18 to make a detour, and that causes the paper P to join to the pair of transport rollers 40 which is located in the upper stream-side locations of the line head 18 in the straight path 24.
Further, when the paper P is transported in the reverse path 28, the first surface and the second surface are reversed and transported to an area which faces the line head 18 in the straight path 24, and then recording is performed on the second surface. Thereafter, the paper P is ejected to the paper receiving tray 20 through the facedown ejection path 30.

Further, in step S7, the line head 18 is raised to the device main body 12 to the upper side of the device height direction, and thus the line head 18 is removed from the device main body 12 (refer to FIG. 18). Also, in FIG. 18, two short-dashed line part and reference symbol 18′ indicate the line head 18 in a state of being removed from the device main body 12, and the reference symbols 19′ indicate the head nozzles of the line head 18 in a state of being removed.
Subsequently, in step S8, a new line head 18 is attached to the device main body 12 while causing the guide pins 23 to pass through the through holes 21 (refer to FIG. 18). Further, in step S9, the guide pins 23 are caused to pass through the guide pin stabilizing members 25, and thus the fastening members 27 is fastened to the device main body 12. Therefore, the horizontal locations of the guide pins 23 are stable, with the result that it is possible to smoothly attach or detach the line head 18 to or from the device main body 12, and thus it is possible to prevent the guide pins 23 from being inclined due to an elevating motion when a mechanism in which the line head 18 elevates according to the kind of the paper is provided.
Subsequently, in step S10, the different-type cable 76, which extends from the control section 90, is attached to the exchanged line head 18 (refer to FIG. 7).
