And an ink absorbing material 37 for receiving ink ejected from the recording head 27 and not landing on the recording material.

Further, the configuration will be described with reference to FIG. 1. In the inkjet printer 1 of the present embodiment, the paper P set in the stacked state in the feeding set unit 13 is transported one by one in order from the highest one. A feeding unit 17 that feeds the paper 16 toward the transport path 16, a transport force that applies a transport force to the paper P that is fed to the transport path 16, guides it to the recording execution area 23, and discharges the paper P after execution of recording to the outside. The recording execution unit 25 including a recording head 27 that performs recording by discharging ink of each color onto the recording surface of the sheet P guided to the recording execution area 23, and the recording execution area 23. A support guide portion 31 having a plurality of ribs 2 for supporting a supported surface opposite to the recording surface of the paper P, and an ink absorbing surface 33 positioned at a position lower than the support surface 9 of the rib 2. An ink absorbing material 37 covering the ink discharge region 35; It is basically formed by Bei.
In addition, in the ink discharge region 35, the ink absorbing material 37 is not indispensable, and in order to reduce the occurrence of ink mist, in addition to the ink absorbing material 37, a fine unevenness may be formed on the surface of the ink discharging region. I do not care.

The feeding set unit 13 includes, for example, a sheet placement unit 15, and the feeding unit 17 has a D-shape as viewed from the side as an example of feeding the sheet P by a pinching feed action with the hopper 18. It is comprised by providing the roller 19 for feeding.
The transport unit 20 includes a pair of nip rollers, and includes a transport roller 21 disposed at an upstream position of the recording execution area 23 and a pair of nip rollers, and is disposed at a downstream position of the recording execution area 23. And a discharge roller 22.

  The recording execution unit 25 includes the recording head 27 and a carriage 29 that is mounted with the recording head 27 and reciprocally moves in the scanning direction in the width direction B of the paper P that intersects the transport direction A of the paper P. Has been.

The support guide portion 31 is a rectangular frame-like member having a recess 39 for mounting the ink absorbing material 37 on its upper surface (FIG. 2). A plurality of fixing ribs 5A, 5B, and 5C functioning as the ribs 2 are provided at appropriate positions in the width direction B of the paper P at upstream and downstream positions of the recess 39.
In addition, a plurality of movable ribs 3 functioning as the ribs 2 which are characteristic constituent members of the present invention to be described later are provided between the fixed ribs 5A provided in the recesses 39.

The ink absorbing material 37 is a rectangular flat plate member as an example that is attached to the concave portion 39 of the support guide portion 31. As the ink absorbing material 37, a porous sponge-like member having ink absorbability is used as an example. When the ink absorbing material 37 is mounted in the recess 39, the support surface 9 of the movable rib 3 and the fixed rib 5A described above is configured to be higher than the ink absorbing surface 33 of the ink absorbing material 37. In order to configure in this way, the ink absorbing material 37 is formed with a plurality of windows 38 that penetrate vertically to receive the movable rib 3 and the fixed rib 5A.
In addition, since the window part 38 which receives the said movable rib 3 opens with the movement of the movable rib 3, the cover film 40 as shown by a virtual line in FIG. It is also possible to close the opening of the window 38.

[Example 1] (See FIGS. 1 to 5)
In the ink jet printer 1 </ b> A according to the first embodiment, the movable rib 3 </ b> A is provided so as to move above the ink absorbing material 37. Specifically, the operation mechanism 41 shown in FIGS. 3 to 5 is incorporated in the support guide portion 31, and the movable rib 3 </ b> A is illustrated by operating the operation mechanism 41 in association with the conveyance of the paper P. In this way, the paper P is transported while being moved in the transport direction A of the paper P.
The operation mechanism 41 is configured by a rack and pinion mechanism including a pinion 43 provided at the bottom as an example of the support guide portion 31 and a rack 45 that meshes with the pinion 43.

The power for rotating the pinion 43 may be obtained from a gear train or the like that transmits power to the conveying roller 21 or may be obtained from a separate independent motor or the like.
The rack 45 is integrally provided with an arm 47 extending upward, and the movable rib 3 </ b> A is attached to an upper end portion of the arm 47 so as to project to the downstream side as an example.
The movable rib 3A is provided as an example so as to be positioned within the installation range 49 of the fixed rib 5A by the urging force of the spring 48 in a state before moving as shown in FIG.

Further, in the present embodiment, the position of the downstream end face 51 of the fixed rib 5A and the position of the downstream end face 53 of the movable rib 3A substantially coincide with each other before the movable rib 3A moves. It has been. As shown in FIG. 5, when the movable rib 3 is moved in the transport direction A at the substantially same speed as the transport speed of the paper P, the leading end 11 of the paper P is curled. Thus, the stroke is set so as to reach the support surface 9 of the fixed rib 5C located downstream of the recess 39 without contacting the lower ink absorbing material 37.
In the present embodiment, the height of the support surface 9 of the movable rib 3A is set to be the same as the height of the support surfaces 9 of the fixed ribs 5A, 5B, and 5C. There may be a slight level difference between the support surfaces 9 as long as the leading edge 11 of the paper P does not contact the ink absorbing material 37.

  Next, based on FIG. 3 to FIG. 5, the operation mode of the movable rib 3 will be described separately (1) before movement, (2) during movement, and (3) after movement.

(1) Before movement (see Fig. 3)
As shown in FIG. 3, in a state before the movable rib 3A moves, the movable rib 3 is positioned within the installation range 49 of the fixed rib 5A by the biasing force of the spring 48, and is downstream of the fixed rib 5A. The positions of the side end face 51 and the downstream end face 53 of the movable rib 3A substantially coincide with each other.
When the paper P to which the conveying force is applied by the conveying roller 21 passes through the fixed rib 5B on the leading end 11 side, further reaches the fixed rib 5A, and further passes the slightly downstream end surface 51 of the fixed rib 5A. The movable rib 3A is configured to start moving.

(2) Moving (see Fig. 4)
When the leading end 11 of the sheet P slightly passes the downstream end face 51 of the fixed rib 5A and the downstream end face 53 of the movable rib 3A at the position before the movement starts, borderless recording with respect to the leading end starts. At this time, since both the movable rib 3A and the fixed rib 5A are located below the paper P, the ink ejected from the recording head 27 is absorbed on the paper P or out of the leading edge of the paper and absorbed by the ink absorber 37. Land on the surface 33. Therefore, the movable rib 3A and the fixed rib 5A are not stained by ink. The movable rib 3 is configured to move in the transport direction A against the biasing force of the spring 48 at substantially the same speed as the transport speed of the paper P that is intermittently transported.
During this movement, the supported surface of the leading end portion 11 of the paper P is supported by the support surfaces 9 of the movable rib 3A and the fixed rib 5A, so that downward curling or deformation is suppressed.

  Further, since the movable rib 3A is provided so as to move above the ink absorbing material 37, it is not necessary to form a slit in the ink absorbing material 37 for sliding the movable rib 3A. Therefore, since it is not necessary to sacrifice the function of the ink absorbing material 37 for the movement of the movable rib 3A, the generation of ink mist can be reduced.

In this embodiment, the timing at which the movable rib 3A starts to move is obtained by counting the transport amount of the paper P from a position sensor that detects the leading end position of the paper P.
That is, the movable rib starts to move at a predetermined timing regardless of whether the tip 11 is curled or deformed, and further moves while supporting the tip 11.
It is also possible to detect the descending amount due to the curl of the leading end portion 11 of the paper P with a separate sensor and start the movement of the movable rib 3 when the predetermined descending amount is reached.

The movement of the movable rib 3A is performed by the operation mechanism 41 described above, and the pinion 43 is attached to the rack 45 and the arm 47 integral with the rack 45 by rotating counterclockwise in FIG. The movable rib 3A is moved to the left in FIG. 4 to be executed.
At this time, the leading end portion 11 of the paper P moves away from the fixed rib 5A to a downstream position where the curling or the like is not suppressed by the fixed rib 5A, but is moved downward by the movable rib 3A that moves together with the paper P. Since curling and the like are suppressed, the leading end portion 11 is conveyed without contacting the ink absorbing surface 33 of the lower ink absorbing material 37.

(3) After movement (see Fig. 5)
When the pinion 43 rotates a predetermined number of times and stops rotating, the movable rib 3A moves in the transport direction A by the moving stroke S and stops.
Thereafter, the leading end 11 of the paper P moves away from the stopped movable rib 3A to a downstream position where the suppression by the movable rib does not reach, but the downstream fixed rib 5C is located at this position. It is conveyed without contacting the ink absorbing surface 33 of the lower ink absorbing material 37 and is delivered to the downstream discharging roller 22.

  After the leading end portion 11 of the paper P is nipped by the discharge roller 22, the pinion 43 rotates in the clockwise direction opposite to that in FIG. 4, and thereby the biasing force of the spring 48 also acts to act the rack 45 and the movable rib 3. To the original position shown in FIG. In this state, recording on the paper P is continued.

Hereinafter, the above-described operation described based on FIG. 3 to FIG. 5 is repeated in the same manner, so that the leading edge of the sheet P is also suppressed with respect to the subsequent sheet P in a state where curling downward of the leading edge 11 is suppressed. Recording of the entire recording surface of the paper P is performed without bringing 11 into contact with the ink absorbing material 37.
In addition, since it is not necessary to reduce the area of the ink absorbing material 37 that accompanies the slide of the movable rib 3A, it is possible to reduce the occurrence of ink mist during borderless recording.
