Description

  The present invention relates to a recording apparatus such as an ink jet printer.

  In general, an ink jet printer is widely known as an example of a recording apparatus that performs recording on a recording medium such as paper. In this printer, normally, after printing is performed by ejecting ink from a recording head onto a sheet to be conveyed, the printed sheet is discharged onto a discharge tray. In such a printer, a paper cassette containing paper is disposed at the bottom of the housing, a paper discharge tray is fixedly disposed above the paper cassette, and a recording head is disposed above the paper discharge tray. (For example, Patent Document 1).

  In such a printer, the paper stored in the paper cassette is conveyed onto a support member (platen) that supports the paper at a position facing the recording head by a pickup roller and a paper feeding roller, and then an image is recorded by the recording head. The paper is discharged onto the paper discharge tray by the paper discharge roller.

  By the way, in the printer as described above, the paper in the paper cassette may be curled (curled) depending on the surrounding humidity and temperature. When the paper in the paper cassette is curled, there is almost no gap between the paper cassette and the paper discharge tray, so that the curled paper comes into contact with the lower surface of the paper discharge tray. In this state, when the curled paper in the paper cassette is transported, the transported paper is caught by unevenness on the lower surface of the paper discharge tray, and the paper is not smoothly transported. .

  Such a problem is not limited to an ink jet printer, and is generally common to recording apparatuses in which a storage unit that stores a recording medium is detachably attached to a housing.

  The present invention has been made paying attention to such problems. An object of the present invention is to provide a recording apparatus capable of suppressing the curled recording medium from being caught by another member even if the recording medium accommodated in the accommodating portion is conveyed while being curled. .

  A recording apparatus that solves the above-described problem is detachably mounted on a housing, a storage unit that stores a recording medium, and the recording medium that is stored in the storage unit on the downstream side along the conveyance path Is fixedly disposed between a recording unit that records on the recording medium when being transported to the recording medium, and the storage unit and another member positioned above the storage unit in the housing, and the storage And a medium regulating member that comes into contact with the curled recording medium when the recording medium accommodated in the section curls.

  According to this configuration, when the recording medium accommodated in the accommodating portion is curled, the curling of the curled recording medium is regulated by the medium regulating member. Therefore, even when the recording medium accommodated in the accommodating portion is conveyed while being curled, the curled recording medium can be prevented from being caught by other members.

In the recording apparatus, it is preferable that the medium regulating member includes a contact surface that contacts the curled recording medium, and the contact surface is smooth.
According to this configuration, since the contact surface is smooth, the recording medium can smoothly slide on the contact surface even when the recording medium curled by the storage unit is conveyed in a state where the recording medium is in contact with the contact surface. Become. For this reason, it becomes possible to smoothly convey the recording medium curled by the accommodating portion.

In the recording apparatus, the contact surface is preferably flat.
According to this configuration, since the contact surface is flat, even if the recording medium curled by the storage unit is conveyed while the recording medium is in contact with the contact surface, the recording medium slides more smoothly on the contact surface. It becomes like this. For this reason, it becomes possible to more smoothly convey the recording medium curled by the accommodating portion.

  In the recording apparatus, the recording apparatus is disposed so as to be slidable above the storage unit, and the recording medium recorded by the recording unit is discharged between the discharge tray and the storage unit. And a support member that supports the discharge tray while guiding the discharge tray in the sliding direction, and the medium regulating member is preferably constituted by the support member.

According to this configuration, since the support member can function as a medium restriction member, the number of parts can be reduced as compared with the case where the medium restriction member is provided separately from the support member.
In the recording apparatus, it is preferable that the support member has a notch.

According to this configuration, for example, it is possible to save space in the casing by arranging another member in the notch in the casing.
In the recording apparatus, it is preferable that a feeding member that feeds the recording medium accommodated in the accommodation portion downstream in the feeding direction is disposed in the cutout portion of the support member in the housing.

According to this configuration, it is possible to ensure the location of the feeding member while avoiding contact between the support member and the feeding member in the housing.
In the recording apparatus, it is preferable that the storage unit includes a plurality of unit storage units that store different types of recording media, and the unit storage units are arranged in the vertical direction.

  According to this configuration, it is possible to easily switch the type of recording medium on which recording is performed.

It slides between a position (position shown in FIG. 4) and a feeding position (position shown in FIG. 5) of a two-dot chain line, also denoted by reference numeral 17B. In the present embodiment, the power source of the upper cassette 17 is the same as the power source of the transport system that transports the paper P, and uses a transport motor (not shown).

Next, the configuration of the ink jet printer 11 will be described in detail.
As shown in FIGS. 4 and 5, the apparatus main body 12 includes a cassette feeding unit 35, a feeding unit 36, a medium conveying unit 37, a recording unit 38, and a feeding unit 39. The cassette feeding unit 35 includes a lower cassette 16, an upper cassette 17, a pickup roller 19, and a separation unit 40 provided at a position facing the front end of the paper P stored in each of the cassettes 16 and 17.

  The lower cassette 16 and the upper cassette 17 provided on the upper side thereof can accommodate a plurality of sheets P1 and P2 in a stacked state, and can be detached from the apparatus main body 12 independently. Further, even if one of the cassettes 16 and 17 is not mounted, it is possible to feed the paper P from the mounted cassette as long as the other is mounted. The upper cassette 17 is slidably displaced between the take-out position (position shown in FIG. 4) and the feeding position (position shown in FIG. 5) by the power of the transport motor (not shown).

  As shown in FIGS. 4 and 5, the pickup roller 19 rotates at the tip of the swinging member 20 that is supported by a support frame (not shown) in the apparatus body 12 so as to be swingable about the swinging shaft 41. It is installed as possible. The pickup roller 19 is rotationally driven by the power of the transport motor (not shown) being transmitted through the gear train in the swing member 20.

  The swing member 20 is provided at a position engageable with the pressing portion 16c (see FIG. 3B) of the lower cassette 16, and a holding mechanism (not shown) capable of holding the pickup roller 19 at an intermediate position; A cam follower (not shown) provided at a position engageable with the stopper 17c of the cassette 17 is provided.

  When the lower cassette 16 is inserted into the apparatus main body 12 in a state where the cassettes 16 and 17 are not mounted or the upper cassette 17 is in the take-out position, the lower cassette 16 is brought into the abutting position (position shown in FIG. 4) in the mounting direction. In the process of moving, a pressing portion 16c (see FIG. 3B) formed at the tip of the lower cassette 16 is engaged with a holding mechanism (not shown). Then, the holding state of the pickup roller 19 by this holding mechanism is released.

  As a result, the pickup roller 19 is lowered to a position in contact with the paper P1 stored in the lower cassette 16. For this reason, when the upper cassette 17 is in the take-out position shown in FIG. 4, the pickup roller 19 contacts the uppermost sheet P1 in the lower cassette 16, and in this state, the transport motor (not shown) When the pickup roller 19 is rotated by driving, the uppermost sheet P1 is sent out from the lower cassette 16 to the downstream side of the feeding path.

  Further, in the process in which the upper cassette 17 is moved from the take-out position (position shown in FIG. 4) inserted into the apparatus main body 12 to the feeding position (position shown in FIG. 5) that becomes the butting position in the mounting direction, the upper cassette 17 The stopper 17c at the distal end engages with a cam follower (not shown) of the swing member 20, and pushes the swing member 20 upward. Thereafter, when the engagement between the stopper 17c and the cam follower (not shown) is released, the pickup roller 19 descends to a position (position shown in FIG. 5) in contact with the paper P2 accommodated in the upper cassette 17.

  For this reason, as shown in FIG. 5, when the upper cassette 17 is in the feeding position, the pickup roller 19 comes into contact with the uppermost one of the sheets P2 accommodated in the upper cassette 17, and in this state, the transport motor By driving (not shown) and the pickup roller 19 rotating, the uppermost sheet P2 is sent out from the upper cassette 17 to the downstream side of the feeding path.

  In addition, even if one of the lower cassette 16 and the upper cassette 17 is not mounted, the paper P can be fed from the other. Further, the uppermost sheet P sent out from one of the cassettes 16 and 17 by the rotation of the pickup roller 19 is separated from the next and subsequent sheets P by the separation unit 40 in the process of being sent out.

  As shown in FIGS. 4 and 5, the feeding unit 36 provided on the downstream side of the feeding path of the separating unit 40 includes a feeding driving roller 44 driven by a transport motor (not shown), a separating roller 45, and the like. And a feeding driven roller 46. The separation roller 45 is in contact with the feed driving roller 44 and again separates the paper P, and reliably feeds only the uppermost paper P to the downstream side of the feed path.

  Further, the sheet P sandwiched between the feeding drive roller 44 and the feeding driven roller 46 is conveyed to the medium conveying unit 37. The medium transport unit 37 includes a transport drive roller 47 that is also driven by a transport motor (not shown), and a transport driven roller 48 that is driven to rotate while being in pressure contact with the transport drive roller 47. The medium P is sent further downstream by the medium transport unit 37.

  As shown in FIGS. 4 and 5, the recording unit 38 provided on the downstream side in the transport direction Y of the medium transport unit 37 includes the carriage 21, the recording head 23, and a support base 49 that faces the recording head 23. Prepare. The support base 49 is supported from below by a frame base 60 as an example of another member that is fixedly arranged above the upper cassette 17 in the apparatus main body 12. Reinforcing ribs 60a are formed on the lower surface of the frame base 60 so as to protrude downward.

  Further, a support member 61 as an example of a medium regulating member having a substantially rectangular plate shape is fixedly disposed between the upper cassette 17 and the frame base 60 in the apparatus main body 12. The support member 61 supports the paper discharge tray 24 so as to be slidable along the transport direction Y (the left-right direction in FIGS. 4 and 5). That is, the support member 61 supports the paper discharge tray 24 while guiding it in the sliding direction (left and right directions in FIGS. 4 and 5).

  The recording head 23 provided at the bottom of the carriage 21 so as to face the paper P is guided in the main scanning direction X (FIGS. 4 and 4) while the carriage 21 is guided by the guide shaft 22 by the power of the carriage motor (not shown). 5, in the process of reciprocating in the direction orthogonal to the paper surface, ink droplets are ejected onto the paper P to print an image on the paper P. At this time, the support base 49 supports the paper P and defines the distance (gap) between the paper P and the recording head 23.

  The feed unit 39 provided on the downstream side of the support base 49 includes a first roller 51 that is driven by a transport motor (not shown), and a second roller 52 that rotates in contact with the first roller 51. . The paper P printed (recorded) by the recording unit 38 is sent to the downstream side in the transport direction Y by the feeding unit 39 and then onto the paper discharge tray 24 slid to the front side of the apparatus main body 12. Discharged.

  The paper discharge tray 24 is driven by a power source common to the operation panel 13, and after the operation panel 13 rotates to a predetermined posture angle to open the movement path of the paper discharge tray 24, the paper discharge tray 24 is a device. It slides from the main body 12 to a position where a predetermined protrusion amount is obtained.

  Further, as shown in FIG. 4, a medium feeding unit capable of feeding paper manually is provided at the rear upper part (upper left part in FIG. 4) of the apparatus main body 12 and exposed when the manual feeding cover 25 is opened. The sheet P can be manually inserted from the feeding port 53 (shown by a two-dot chain line in FIG. 4).

  The manually inserted paper P is inserted between the feed driving roller 44 and the feed driven roller 46, and in this state, a transport motor (not shown) is driven, so that the medium transport unit 37 and the feed unit 39 are driven. Is conveyed downstream in the conveyance direction Y. That is, the feeding of the paper P from the cassettes 16 and 17 and the feeding of the paper P by manual feeding take a common transport path after the nip point between the feeding driving roller 44 and the feeding driven roller 46.

Next, the configuration of the support member 61 will be described in detail.
As shown in FIG. 6, the central portion of the support member 61 in the width direction X at the downstream end of the paper P in the paper feeding direction K has a substantially rectangular shape extending in the direction opposite to the paper feeding direction K. A notch 62 is formed. The width of the notch 62 is set to about one third of the entire width of the support member 61, and the length of the notch 62 in the feeding direction K is set to about one third of the entire length of the support member 61.

  As shown in FIG. 5, since the pickup roller 19 and the swing member 20 are disposed in the notch 62 in the apparatus main body 12, the contact between the support member 61 and the pickup roller 19 and the swing member 20. Is avoided.

  As shown in FIG. 6, a large number of reinforcing ribs 63 each having a substantially hexagonal shape are formed at both ends in the width direction X on the upper surface of the support member 61 (the surface on the side that supports the paper discharge tray 24). Yes. Further, a reinforcing rib 64 in the form of a lattice is formed at a position upstream of the notch 62 in the center in the width direction X on the upper surface of the support member 61 in the feeding direction K.

  As shown in FIGS. 4 and 7, the width direction X of the uppermost sheet P <b> 2 in the upper cassette 17 is disposed at both ends in the width direction X on the lower surface (the surface on the upper cassette 17 side) of the support member 61. A flat and smooth contact surface 65 that can come into contact with the curled paper P2 is formed. That is, the contact surface 65 does not have any unevenness that causes the curled paper P2 to be caught when the curled paper P2 is moved in the feeding direction K in a contacted state.

  A plurality of (in this example, five) ribs 66 extending in the feeding direction K are located upstream of the notch 62 in the center in the width direction X on the lower surface of the support member 61 in the feeding direction K. They are formed at equal intervals in the width direction X. Each rib 66 gradually decreases in height toward the downstream side in the feeding direction K, and the tip surface in the height direction is smooth. Each rib 66 can come into contact with the curled paper P2 when curled so that the central portion in the width direction X of the uppermost sheet P2 in the upper cassette 17 rises.

Next, the operation of the ink jet printer 11 will be described by focusing on the case where the paper P2 in the upper cassette 17 is printed.
When printing the paper P2 in the upper cassette 17, it is necessary to slide the upper cassette 17 at the take-out position to the feeding position. At this time, depending on conditions such as ambient humidity and temperature, the paper P2 in the upper cassette 17 may be curled so that both ends in the width direction X are warped. When both ends of the curled paper P2 in the width direction X come into contact with the contact surface 65 of the support member 61, the paper P2 is no longer curled. That is, the curling of the paper P <b> 2 is suppressed by the support member 61.

  In this state, when the upper cassette 17 is slid from the take-out position to the feeding position, the contact surface 65 is flat and smooth, so the curled paper P2 slides on the contact surface 65 while contacting the contact surface 65. . As a result, when the upper cassette 17 is slid from the take-out position to the feeding position, the curled paper P2 is restrained from being caught on the rib 60a of the frame base 60 or the like.

  Further, when curling so that the central portion in the width direction X of the paper P2 in the upper cassette 17 at the take-out position is raised, the central portion in the width direction X of the curled paper P2 is the rib 66 of the support member 61. To touch. As a result, the paper P2 is no longer curled. That is, the curling of the paper P <b> 2 is suppressed by the support member 61.

  In this state, when the upper cassette 17 is slid from the take-out position to the feeding position, the front end surface in the height direction of each rib 66 is smooth. Slide on the rib 66. As a result, when the upper cassette 17 is slid from the take-out position to the feeding position, the curled paper P2 is prevented from being caught by the rib 60a of the frame base 60 or the like.

  By the way, if the support member 61 is not provided, when the upper cassette 17 is slid from the take-out position to the feeding position, the curled paper P2 is caught on the rib 60a of the frame base 60, thereby causing paper jam. There is a problem that there is a risk that. For this reason, in order to avoid the curled paper P2 from being caught by the rib 60a of the frame base 60, it is conceivable to secure a large space between the upper cassette 17 and the rib 60a of the frame base 60. Then, there is a problem that the height of the apparatus main body 12 is increased.

  Subsequently, when the upper cassette 17 is slid from the take-out position to the feeding position, the pickup roller 19 comes into contact with the uppermost sheet P2 stored in the upper cassette 17 as shown in FIG. . When the pickup roller 19 is rotated in this state, the uppermost sheet P2 is sent out from the upper cassette 17 to the downstream side in the feeding direction. The paper P2 sent out from the upper cassette 17 is transported in the transport direction Y along a predetermined transport path while being reversed at the rear part in the apparatus main body 12. The paper P <b> 2 transported in the transport direction Y is printed by the recording unit 38 and then discharged onto the paper discharge tray 24.

According to the above embodiment, the following effects can be obtained.
