The roller 37 (described later) can be brought into a pressure contact state (FIG. 6) and can be separated (FIG. 4).

  In the movable tray 23, a plurality of openings 24a are formed at appropriate intervals along the paper width direction at a position corresponding to the leading edge of the paper, and the opening 24a feeds the stored paper P. The roller 37 can be pressed. Reference numeral 12c denotes a paper tip support wall configured by the cassette body 12 for supporting the paper tip. The paper P accommodated in the state in which the paper cassette 11 is mounted is supported in a state where the front end thereof is in contact with the paper front end support wall 12c.

  Next, the internal configuration of the ink jet printer 1, specifically, the paper conveyance path will be described with reference to FIGS. 4 to 6. In a state where the sheet cassette 11 configured as described above is mounted vertically, a feeding roller 37 as a “reverse roller” is provided at a position facing the front end of the sheet cassette 11. A plurality of feed rollers 37 are arranged on a drive shaft 37a extending in the paper width direction at an appropriate interval in the paper width direction (FIG. 2), and are driven by a motor (not shown) to be in contact with the front end of the paper.

That is, the carriage 58 has a bearing portion through which the carriage guide shaft 55 is inserted. However, since the carriage 58 is provided in an inclined posture as shown in the drawing, there is a tendency to rotate about the carriage guide shaft 55. However, since the guided portion 58 a is configured to sandwich the carriage guide plate 56, the above-described tendency of rotation is stopped, and the posture of the carriage 58 is determined.

  As described above, in this embodiment, the ink cartridge 6 is provided on the apparatus main body side, that is, the ink cartridge 6 is configured as a so-called off-carriage type provided independently from the carriage 58. However, the present invention is not limited to this, and a so-called on-carriage type in which the ink cartridge 6 is mounted on the carriage 58 may be used. In this embodiment, the recording is performed while the carriage 58 moves in the paper width direction (serial printer). However, a fixed recording head that covers the paper width and does not move the carriage 58 in the paper width direction is used. It may be used. Furthermore, the recording method is not limited to the ink jet recording method, and other recording methods may be used.

  Next, the guide member 48 disposed to face the ink jet recording head 59 is formed of a resin material, and supports the paper P to define a gap between the recording surface of the paper P and the ink jet recording head 59.

Note that the broken lines in FIG. 6 indicate the trajectory of the paper P transported along the paper transport path.

〓〓〓2. Measures to prevent equipment overturning
Next, measures for preventing overturn in the inkjet printer 1 will be described.
Since the inkjet printer 1 configured as described above has a vertically-arranged configuration as described above, the inkjet printer 1 has a property of easily falling down due to the configuration at the time of installation. For this reason, in the inkjet printer 1 according to the present embodiment, the conveyance drive roller 46 that is formed by a shaft body extending in the x direction (direction orthogonal to the sheet conveyance direction) and conveys the sheet P by rotating, and the inkjet recording head 59. These are arranged in the central region with respect to the dimension in the y direction (the depth (thickness) direction of the apparatus).

  More specifically, in FIG. 4, reference numeral D denotes a dimension in the y direction, and reference numeral C denotes an occupied area of the transport driving roller 46 and the inkjet recording head 59 in the y direction. Symbols A and B indicate distances from the device external surface to the occupied area C in the y direction. In the present embodiment, although the distances A and B are not strictly 1: 1, the ratio based on one side is configured to be [1]: [0.7 to 1.3]. And arranged so as to be located in the central region with respect to the dimension D in the y direction.

  As described above, the inkjet printer 1 according to the present embodiment causes the transport drive roller 46 and the inkjet recording head 59 as heavy objects to be in the y direction (the depth (thickness) direction of the apparatus) as a “dimension direction that is easy to collapse”. On the other hand, since it is arranged in the central region, it is possible to maintain the balance of the apparatus, and it is possible to configure a vertical ink jet printer that does not easily fall over.

  In the present embodiment, in addition to the transport drive roller 46 and the inkjet recording head 59, the feed roller 37 as a reverse roller that reverses the paper feed direction is also centered with respect to the y direction (depth (thickness) direction) of the apparatus. Arranged in the area. In other words, in the present embodiment, the feeding roller 37 having a large diameter is a heavy object, similar to the transport driving roller 46 and the inkjet recording head 59, and the feeding roller 37 as such a heavy object is smaller than the y-direction dimension. By arranging in the central region, it is possible to configure a vertical ink jet printer that is more difficult to fall.

  In the present embodiment, as described above, the transport driving roller 46, the inkjet recording head 59, and the feeding roller 37 are arranged in the central region with respect to the y direction (depth (thickness) direction) of the apparatus. However, the present invention is not limited to this, and if there is another heavy object, it can be arranged in the central region together to form a vertical ink jet printer that is more unlikely to fall down. Examples of such heavy objects include a carriage guide shaft 55 and a power supply unit (not shown), in addition to the rotation shaft of the discharge driving roller 51 and the components of the paper transport path.

  In the present embodiment, as described above, all of the transport driving roller 46, the inkjet recording head 59, and the feeding roller 37 are arranged in the central region with respect to the dimension in the y direction (the depth (thickness) direction of the apparatus). Of these, any one or two of them can be the target to be arranged in the central region.

  Further, by configuring as described above, the center of gravity G (not shown) of the entire apparatus can be set in the central region with respect to the dimension in the y direction (the depth (thickness) direction of the apparatus), and the vertical position is difficult to fall down. A stationary ink jet printer can be configured.

  In addition, by setting the center of gravity G below the center position in the z direction (device height direction), it is possible to configure a vertical ink jet printer that is more unlikely to fall. In the present embodiment, as is clear from FIG. 4, the transport drive roller 46, the inkjet recording head 59, and the feed roller 37 are disposed below the center position in the z direction (device height direction). The center of gravity G of the entire apparatus is set below the center position in the z direction (apparatus height direction), thereby constituting a vertically installed ink jet printer that is more unlikely to fall.

  In the present embodiment, the paper cassette 11 is arranged at one end with respect to the dimension in the y direction (depth (thickness) direction of the apparatus). For this reason, the center of gravity G of the entire apparatus moves greatly in the y direction depending on whether the maximum number of sheets is accommodated or the minimum number of sheets, so that the ease of overturning may be affected. Regardless of the number of sheets stored, if the arrangement and weight of heavy objects are set so that the center of gravity G of the entire apparatus falls within, for example, the region C of FIG. You can also

〓〓〓3. The position of the print head in the transport path
Next, the arrangement position of the inkjet recording head 59 in the paper conveyance path will be described.
In the inkjet printer 1 according to the present embodiment, as described above, the paper P fed from the paper cassette 10 toward the lower side of the apparatus is reversed by the feed roller 37 and the guide members 40 and 41 on the outside thereof. The path section has a substantially U-shaped sheet transport path that reverses the feeding direction and transports the sheet toward the upper side of the apparatus. However, the recording section including the ink jet recording head 59 is downstream of the inversion path section. Is provided.

  Here, if the inkjet recording head 59 is provided upstream or in the middle of the reverse path portion, it is necessary to bend the sheet tightly after the end of recording, which may lead to a decrease in recording quality. . In particular, the paper after ink jet recording may have a tendency to wave in the paper width direction (cockling). If the paper in such a state is curved and inverted, the cockling is crushed and wrinkles are generated. There is a risk of doing.

  However, in the ink jet printer 1 according to the present embodiment, as described above, the ink jet recording head 59 is provided on the downstream side of the reversing path portion, and the paper P on which the recording has been performed is performed with a substantially U-shaped curved reversing path. Since it is not curved, an appropriate recording result desired can be obtained.

  In the present embodiment, the sheet conveyance path is inclined downstream from the reverse path formed by the feeding roller 37 (angle α shown in FIG. 4 is 12 ° as an example), but the present invention is not limited to this. For example, as shown in FIG. 9A, the downstream side from the reversing path portion formed by the feeding roller 37 may be along the vertical direction (that is, the angle α shown in FIG. 4 is 0 °).

  In the present embodiment, the ink jet recording head 59 is provided outside the substantially U-shaped sheet conveyance path. Therefore, if a paper jam occurs, the removal process is facilitated. However, as shown in FIG. 9B, the inkjet recording head 59 can also be provided inside the substantially U-shaped paper conveyance path. In this case, it is not necessary to secure a large space for installing the ink jet recording head 59 and the carriage 58 outside the paper transport path, and the apparatus can be downsized.

〓〓〓4. Form of paper transport path
Next, the form of the paper conveyance path in the inkjet printer 1 will be described in further detail. As shown in FIG. 4, the paper transport path of the inkjet printer 1 according to the present embodiment feeds the paper P from the paper cassette 11 set along the vertical direction toward the lower side of the apparatus, and feeds the roller 37. Is a substantially U-shaped transport path that reverses the feeding direction by the reversing path portion formed by the above-described apparatus and transports it toward the upper side of the apparatus, but the reversing path section formed by the feeding roller 37 changes the transport direction from downward to upward. The path after switching to is inclined toward the paper cassette 11 side.

  The angle α shown in FIG. 4 indicates the inclination angle, and is set in a range of 0 ° <α <90 °. In the present embodiment, α = 12 ° is set as an example. As described above, since the path after the conveyance direction is switched from the downward direction to the upward direction by the feeding roller 37 is inclined toward the paper cassette 11, the empty space is formed above the inclined path portion. By disposing the ink jet recording head 59 and the carriage 58 in the space, an increase in the thickness direction dimension (y direction dimension) of the apparatus can be avoided.

  Further, since the sheet conveyance path is inclined, the sheet P does not fluctuate when the sheet P is discharged upward, and the posture can be stabilized. In the present embodiment, the ink jet recording head 59 is arranged with the head surface inclined on the inclined path, and the paper guide surface (surface facing the recording head) of the guide member 48 is arranged inclined. However, these are not limited to the inclined path, and may be provided before and after, for example, a vertical path or a horizontal path.

  Further, in the present embodiment, the paper discharge direction by the discharge driving roller 51 and the discharge driven roller 52 constituting the paper discharge means is directed to the paper cassette 11, whereby the paper P to be discharged as shown in FIG. The paper cassette 11 (specifically, the upper outer cover 15 or the upper outer cover 15 and the upper inner cover 16 in this embodiment) is discharged while being in sliding contact.

  Accordingly, the posture of the discharged paper P is further stabilized. Further, when the discharged paper P is pressed against the already discharged paper P, the already discharged paper P is deposited in an orderly manner without flapping. Furthermore, since a part of the paper cassette 11 can be used as a stacker, the apparatus can be reduced in size and cost by reducing the number of parts.

  In the present embodiment, as a result of the paper discharge direction toward the paper cassette 11 as described above, the paper cassette 11 and the paper discharge port 4 are located in the thickness direction (y direction) of the apparatus from the center position. It is the state arrange | positioned in the position biased to the edge of one side. Therefore, a relatively wide continuous space can be secured on the upper surface of the apparatus, and the degree of freedom in apparatus layout can be increased. For example, when the operation panel 3 including operation switches or the like is arranged on the upper surface of the apparatus as in the present embodiment, the degree of design freedom can be ensured.

Needless to say, the embodiment described above is merely an example, and the present invention is not limited thereto. For example, in the present embodiment, the present invention is applied to an ink jet printer as an example of a recording apparatus. However, the present invention can also be applied to a general liquid ejecting apparatus.
Here, the liquid ejecting apparatus uses an ink jet recording head, and is not limited to a recording apparatus such as a printer, a copying machine, and a facsimile machine that discharges ink from the recording head to perform recording on a recording medium. And a device for ejecting a liquid corresponding to the application from a liquid ejecting head corresponding to the ink jet recording head to an ejected medium corresponding to the recording medium, and attaching the liquid to the ejected medium.

  In addition to the recording head, as a liquid ejecting head, a color material ejecting head used for manufacturing a color filter such as a liquid crystal display, and an electrode material (conductive paste) used for forming an electrode such as an organic EL display or a surface emitting display (FED) Examples thereof include an ejection head, a bioorganic matter ejection head used for biochip production, and a sample ejection head as a precision pipette.
