  According to the recording apparatus disclosed in Patent Document 1, in order to realize a configuration in which a sheet that pops up in the insertion direction is restricted by an inertial force due to insertion, the number of parts increases and the configuration becomes complicated. Is concerned that the cost will increase.

  In addition, in the recording apparatus, there is a case where the rigidity of the discharge tray itself can not be sufficiently secured due to downsizing or the like in the discharge tray which receives the sheet to be discharged after being printed by the recording unit. In that case, when the discharge tray is bent, it is not possible to stack the sheets on the discharge tray, which causes a problem such as a drop of the sheet.

  Therefore, there has been a demand for a recording device that prevents jumping out of the sheet in the insertion direction of the medium storage tray with a simple configuration, and a recording device that can stably stack the sheets on the discharge tray with a simple configuration. .

  The present invention has been made to solve at least a part of the above-described problems, and can be realized as the following modes or application examples.

According to the recording apparatus of this application example, the movement of the medium in the insertion direction (jump-out) due to the inertial force at the time of insertion can be restricted by the restriction member being installed at the upper part of the medium storage tray. Therefore, with the simple configuration in which the regulating member is installed on the upper part of the medium storage tray, it is possible to prevent the medium from jumping out in the insertion direction when the medium storage tray is mounted.
Generally, the medium storage tray in the recording apparatus is installed at the lower part of the apparatus main body. In other words, the recording unit is generally disposed above the medium storage tray. Therefore, for example, a medium transport path for feeding the medium from the medium storage tray to the recording unit is formed to move the medium of the medium storage tray upward. Therefore, the medium can be easily moved upward along the medium transport path by the inertia force at the time of insertion of the medium storage tray. In view of such a situation, the movement of the medium in the insertion direction and the upward direction (jump-out) can be effectively restricted by providing the restriction member at the upper portion of the medium storage tray.

<Configuration and Operation of Regulating Member>
FIG. 7A is a perspective view showing a state in which the restriction member 60 is installed on the frame 13. FIG. 7B is a perspective view showing a state in which the first medium storage tray 21 on which sheets are stacked is mounted to the mounting portion 24. As shown in FIG. FIGS. 7A and 7B both show the right end in the width direction of the first medium storage tray 21 cut along the depth direction for convenience of explanation.

  As shown to FIG. 7A, the limitation member 60 of this embodiment is comprised by the plate-shaped member. The restricting member 60 is installed to project downward from the lower surface of the rear end of the frame 13 located at the upper portion of the first medium storage tray 21. Further, a pair of restriction members 60 are provided separately in the width direction. Further, the restricting member 60 is installed with a predetermined amount of space between the front end surface 601 of the restricting member 60 and the upper surface of the sheets stacked on the first medium storage tray 21 by a predetermined maximum number.

  The restricting member 60 is installed from the frame 13 toward the first medium storage tray 21. The second medium storage tray 22 and the discharge tray 23 are disposed between the frame 13 and the first medium storage tray 21.

(1) According to the printer 1 of the present embodiment, the regulating member 60 formed of a plate-like member is disposed to project downward from the frame 13 positioned above the first medium storage tray 21. With such a simple configuration, the movement (protrusion) of the sheet A in the insertion direction due to the inertial force at the time of insertion of the first medium storage tray 21 can be restricted by abutting on the restriction member 60. Moreover, since it is the simple structure of making the control member 60 comprised by a plate-shaped member project downward from the flame | frame 13, and installing it, and there may be few number of parts, cost increase can be minimized.

  Generally, the medium storage tray in the recording apparatus (printer) is installed at the lower part of the apparatus main body. In other words, the recording unit is generally disposed above the medium storage tray. Therefore, for example, a medium transport path for feeding the medium from the medium storage tray to the recording unit is formed to move the medium of the medium storage tray upward. Therefore, the medium can be easily moved upward along the medium transport path (including the guide slope 391 as in the present embodiment) by the inertia force at the time of insertion of the medium storage tray. In view of such a situation, including the present embodiment, the restriction member is installed at the upper part of the medium storage tray, thereby effectively restricting the movement (popout) in the insertion direction and the upward direction of the medium.

FIG. 8B is a perspective view showing a state in which the discharge tray 23A provided with the restriction member 61 is mounted to the mounting portion 24 (not shown in FIG. 8B). FIG. 8C is a perspective view showing a state in which the first medium storage tray 21 on which the sheets are stacked is mounted to the mounting portion 24 (not shown in FIG. 8C).

<Configuration and Operation of Regulating Member>
In the present embodiment, the installation position and configuration of the restriction member are different from those in the first embodiment. In the present embodiment, the restricting member 61 is disposed on the discharge tray 23A which can be advanced and retracted in the depth direction, which is located above the first medium storage tray 21. In other words, the discharge tray 23A of the present embodiment has a configuration in which the discharge tray 23 of the first embodiment is provided with the restriction member 61. As shown in FIG. 8A, the regulating member 61 is installed on the lower surface of the end portion 231 on the rear surface side of the discharge tray 23A. Further, the restriction member 61 is disposed along the depth direction on the left side in the width direction.

  The regulating member 61 is roughly configured by a biasing member 611, a stopper member 612, and a guiding member 613. The biasing member 611 is configured by a tension coil spring in the present embodiment. The stopper member 612 is formed in a flat rod shape, and moves in the insertion direction following the biasing force of the biasing member 611 (coil spring). The guide member 613 movably guides the stopper member 612 and holds the stopper member 612.

  The stopper member 612 is guided by the guide member 613 and moves in the insertion direction following the biasing force of the biasing member 611, thereby extending a predetermined amount from the end portion 231 on the back side of the discharge tray 23A in the insertion direction. It will be out. In other words, the restriction member 61 of the present embodiment is configured to extend from the discharge tray 23A in the insertion direction. As shown in FIG. 8B, in a state where the discharge tray 23A on which the regulating member 61 is installed is mounted on the mounting portion 24, the regulating member 61 (stopper member 612) extending in the insertion direction is in a state of blocking the sheet conveyance path. .

  Here, when the first medium storage tray 21 in which the predetermined maximum number of sheets of paper A is stacked is mounted on the mounting unit 24, the paper A moves in the insertion direction (rear direction) by the inertia force at the time of insertion. It will be in the state of moving upward along the guiding slope 391. However, as shown in FIG. 8C, since the restricting member 61 is installed, the restricting member 61 (stopper member 612) abuts on the sheet A which is going to move in the upper direction beyond the guiding slope 391. Can restrict the movement beyond the allowance.

  When printing on a sheet of paper, the discharge tray 23A is expanded from the accommodated state by the discharge tray drive unit (not shown) as in the case of the discharge tray 23 of the first embodiment. Specifically, the discharge tray 23A is expanded to the front side of the apparatus main body 12 by pushing the front cover 20 back to the front side by the discharge tray driving unit and moving backward (moving in the direction opposite to the insertion direction). Do.

  Following the retraction of the discharge tray 23A, the stopper member 612 of the regulating member 61 retracts while extending from the end 231 in the insertion direction. As a result, the stopper member 612 is opened from the state of blocking the sheet conveyance path, and the restriction on the movement of the sheet is released. Then, when printing on a sheet, the pickup roller 42 can separate and convey one sheet at a time.

  The discharge tray drive unit may not be driven electrically. When printing on paper, the user turns the front cover 20 to the front side. Thereafter, a finger may be put on the end on the front side of the discharge tray 23A and retracted (pulled out) to be deployed on the front side.

According to the second embodiment described above, the following effects can be obtained.
(1) According to the printer 1 of the present embodiment, the restricting member 61 provided on the discharge tray 23A includes the biasing member 611 and the stopper member 612, and the biasing member 611 biases the stopper member 612. The stopper member 612 extends from the discharge tray 23A in the insertion direction. With such a simple configuration, it is possible to restrict the movement (jump-out) in the insertion direction of the sheet A due to the inertia force at the time of insertion by allowing the stopper member 612 to abut. Further, as the discharge tray 23A moves in the direction opposite to the insertion direction, the stopper member 612 extending from the discharge tray 23A in the insertion direction follows and the stopper member 612 also moves in the direction opposite to the insertion direction. Thus, by restricting the transport path of the sheet A from the blocking state, the restriction on the movement of the sheet A is released. Therefore, the simple configuration of the biasing member 611 and the stopper member 612 and the movable movement of the discharge tray 23A can prevent the movement (jump-out) of the sheet A in the insertion direction and release the restriction of the movement. it can.

Modification of Second Embodiment
In the second embodiment described above, the discharge tray 23 of the first embodiment includes the restricting member extending in the insertion direction, and the restricting member 61 having the biasing member 611 and the stopper member 612 is described. did. However, in addition to the configuration of such a regulating member 61, the discharge tray 23 may be provided with a regulating member configured to extend in the insertion direction. For example, a plate-like member extending in the insertion direction from the rear end of the discharge tray 23 may be provided as the restriction member. In this case, when the discharge tray 23 is attached to the attachment portion 24, the plate-like member as the restricting member blocks the conveyance path of the sheet A of the first medium storage tray 21, and in the insertion direction of the sheet A by the inertia force. Control the movement of the Further, as in the second embodiment, at the time of printing, the transport path can be opened by pulling out the discharge tray 23 provided with the regulating member.

  In the second embodiment, although the biasing member 611 configured by a tension coil spring is used, a compression coil spring may be used, or a leaf spring or the like may be used. Basically, any biasing member can be used as long as it can extend the stopper member 612 from the end portion 231 on the back side of the discharge tray 23A in the insertion direction.

Third Embodiment
FIG. 9A is a schematic cross-sectional view showing the configuration of a second medium storage tray 22A according to the third embodiment. FIG. 9B is a schematic cross-sectional view showing a state in which the insertion of the first medium storage tray 21A into the mounting portion 24 is started. FIG. 9C is a schematic cross-sectional view showing a state in which the second medium storage tray 22A moves in the insertion direction and blocks the sheet conveyance path. FIG. 9D is a schematic cross-sectional view showing a state in which the second medium storage tray 22A is moved in the direction opposite to the insertion direction to open the sheet conveyance path.

  As shown in FIG. 9A, the second medium storage tray 22A of the present embodiment is provided with a biasing member 222 extending in the depth direction and a support portion which is installed in the vicinity of the end portion 223 on the back side to support and fix the biasing member 222. It has 221. In addition, as the biasing member 222, for example, a compression coil spring can be used.

  A rack gear (not shown) extending in the depth direction is formed on the upper surface of the second medium storage tray 22A, and a pinion gear 71 engaged with the rack gear and rotatably fixed is installed. The rack gear and the pinion gear 71 constitute an accommodation tray drive unit 70. The storage tray drive unit 70 further includes a drive motor (not shown) for rotating the pinion gear 71 and the like.

  When the second medium storage tray 22A is mounted on the mounting portion 24, the end portion 224 on the front side of the second medium storage tray 22A is located on the front side of the apparatus main body 12. Further, the end portion 223 on the back side is at a position spaced farther to the front side than the guide slope 391 located on the back side, and is in a state of opening the transport path of the first medium storage tray 21A.

  As shown in FIG. 9B, the first medium storage tray 21A is provided with a projection 211 for pressing the biasing member 222 from the front side. Here, as shown in FIG. 9B, in order to mount the first medium storage tray 21A on which the user has stacked a predetermined maximum number of sheets on the mounting unit 24, the user can move the first medium storage tray 21 in the insertion direction. Start pushing.

  When the insertion is continued, the projection 211 of the first medium storage tray 21A abuts on the front end of the biasing member 222. When the movement in the insertion direction is continued even after the contact, the biasing member 222 starts to be compressed by the movement force. Further, by continuing the movement in the insertion direction, when the biasing member 222 reaches a predetermined compression force, the second medium storage tray 22A starts to move in the insertion direction. In other words, the second medium storage tray 22A moves in the insertion direction in conjunction with the movement of the first medium storage tray 21A in the insertion direction. In this case, the pinion gear 71 follows the movement of the second medium storage tray 22A in the insertion direction by a clutch mechanism (not shown) provided between it and the drive motor, and performs rotation to allow movement. ing.

  As shown in FIG. 9C, the second medium storage tray 22A is at a position where the second medium storage tray 22A blocks the transport path before the first medium storage tray 21A moves to the predetermined position of the mounting portion 24 by the compression force of the biasing member 222. The rear end 223 is moved to be positioned. By this operation, movement (jumping out) of the sheets stacked on the first medium storage tray 21A in the insertion direction due to the inertial force can be restricted by contacting the bottom surface or the like of the second medium storage tray 22A. .

  Next, an operation of the second medium storage tray 22A when printing is performed on a sheet in the first medium storage tray 21A after the first medium storage tray 21A has moved to a predetermined position of the mounting unit 24 will be described. .

  When a print command is instructed from the control unit to the first medium storage tray 21A mounted at a predetermined position, the storage tray drive unit 70 drives the drive motor to rotate the pinion gear 71. By the rotation of the pinion gear 71 meshing with the rack gear, the second medium storage tray 22A starts moving in the direction opposite to the insertion direction against the urging force of the urging member 222. Then, as shown in FIG. 9D, when the front end portion 224 of the second medium storage tray 22A is positioned on the front side of the apparatus main body 12, the movement is ended. The first medium storage tray 21A holds the inserted position. By restricting the movement of the sheet A, the sheet transport path is released from the blocking state by this series of operations. Then, when printing on a sheet, the pickup roller 42 can separate and convey one sheet at a time.

According to the third embodiment described above, the following effects can be obtained.
(1) According to the printer 1 of the present embodiment, the second medium storage tray 22A is located above the first medium storage tray 21A, and the second medium storage tray 22A is a biasing member of the second medium storage tray 22A. 222, a protrusion 211 or the like of the first medium storage tray 21A moves in the insertion direction to move the sheet from the first medium storage tray 21A inserted in the mounting portion 24 in the insertion direction by an inertial force at the time of insertion Regulate movement. Therefore, with the simple configuration of the second medium storage tray 22A moved in the insertion direction, it is possible to prevent the sheet from jumping out in the insertion direction when the first medium storage tray 21A is mounted.

<Modified Example 1 of Third Embodiment>
In the third embodiment described above, at the end of recording (printing) by the recording unit 50 or when the power is off, the storage tray drive unit 70 as a drive unit drives the drive motor before executing the operation. The pinion gear 71 is rotated. Then, the second medium storage tray 22A may be moved so that the end 223 on the back side is positioned at a position blocking the transport path by moving in the insertion direction by the rotation of the pinion gear 71 meshing with the rack gear.

  As described above, by operating the storage tray drive unit 70, when the printing is ended or the power is turned off, even if the first medium storage tray 21A is inserted and removed after the operation is performed, the second medium storage tray 22A Is located at a position where it blocks the transport path, it is possible to regulate the movement of the sheet.

<Modified Example 2 in Third Embodiment>
In the third embodiment, the storage tray drive unit 70 includes a pinion gear 71, a drive motor, a clutch mechanism, a rack gear installed in the second medium storage tray 22A, and the like. Further, the first medium storage tray 21A is provided with a protrusion 211, and the second medium storage tray 22A is provided with a biasing member 222, a support portion 221, and the like. Then, in conjunction with the movement of the first medium storage tray 21A in the insertion direction, the second medium storage tray 22A is moved to a position where the transport path is blocked.

For example, the pinion gear 71 constituting the storage tray drive unit 70, the drive motor, the rack gear installed in the second medium storage tray 22A, and the first medium storage tray 21A are inserted. It is good also as composition using a sensor etc. which detect having started.

  With this configuration, when the sensor detects that insertion of the first medium storage tray 21A is started by the sensor, the drive motor starts driving, rotates the pinion gear 71, and stores the second medium by the rack gear engaged with the pinion gear 71. The tray 22A may be moved to a position at which the transport path is blocked. According to this configuration, movement (jumping out) of the sheet at the time of insertion of the first medium storage tray 21A can be restricted. In other words, the storage tray drive unit 70 regulates the movement (jump-out) of the sheet by moving the second medium storage tray 22A in the insertion direction in conjunction with the movement of the first medium storage tray 21A in the insertion direction. It is also good.

  Further, at the time of printing, the drive motor is driven to rotate the pinion gear 71, and the rack gear engaged with the pinion gear 71 moves the second medium storage tray 22A in the direction opposite to the insertion direction to open the transport path. It is possible to release the restriction on the movement of the sheet.

<Modified Example 3 in Third Embodiment>
In the third embodiment, the second medium storage tray 22A is moved in the insertion direction to a position where the medium transport path of the first medium storage tray 21A is blocked. In this case, the position at which the medium transport path of the first medium storage tray 21A is blocked and the position at which the second medium storage tray 22A can deliver its own medium may be the same position. In other words, when the second medium storage tray 22A moves to a position where it can deliver the medium, movement of the medium moving in the insertion direction of the first medium storage tray 21A may be restricted.

Note that the state of the sheet Aa illustrated in FIGS. 10B and 10C is shown as an image for convenience of description.

<Structure of Output Tray>
Similar to the discharge tray 23 of the first embodiment, the discharge tray 23B of the present embodiment is installed to be movable back and forth in the depth direction, and switches between a state accommodated in the apparatus main body 12 and a state expanded to the front side It is configured to be possible. Further, when printing is performed, similarly to the discharge tray 23, the discharge tray 23B is in the unfolded state, and receives the sheet to be discharged on the upper surface. Here, the direction in which the printed sheet is discharged (the -Y direction) is hereinafter referred to as the discharge direction.

  As shown in FIGS. 10A and 10B, the discharge tray 23B generally has a flat plate-like receiving portion 85, and a stepped portion 86 formed one step higher than the receiving portion 85 on the end side of the receiving portion 85 in the discharge direction. , Is configured. On an upper surface 86a of the stepped portion 86, a first protrusion 81 and a second protrusion 82, which project upward and receive the sheet, are respectively formed in a pair. The upper surface 85 a of the receiving portion 85, the first protrusion 81, and the second protrusion 82 receive the discharged sheet.

  The first protrusions 81 are provided one by one on both sides in the width direction orthogonal to the discharge direction on the end side of the discharge tray 23B in the discharge direction. In addition, the first protrusions 81 are disposed symmetrically with respect to a center line C (or a plane perpendicular to the upper surface 85 a that divides the width direction into two) that divides the width direction of the discharge tray 23B into two. The first protrusion 81 has an inclined surface 81a along the inclined surface 86b of the step 86, and the cross section along the discharge direction is formed in a triangular shape.

  Similarly to the first protrusions 81, the second protrusions 82 are provided one by one on both sides in the width direction orthogonal to the discharge direction on the end side of the discharge tray 23B in the discharge direction. Further, similarly to the first protrusion 81, the second protrusions 82 are installed symmetrically with respect to a center line C (or a plane perpendicular to the upper surface 85a that divides the width direction into two) dividing the width direction of the discharge tray 23B into two. ing. The second protrusion 82 has an inclined surface 82a, and the cross section along the discharge direction is formed in a trapezoidal shape.

  As shown in FIG. 10A, in the present embodiment, the second protrusion 82 is further disposed in the discharge direction compared to the first protrusion 81, and is disposed closer to the center in the width direction. Then, as shown in FIG. 10B, the height H2 from the upper surface 86a of the step 86 of the second protrusion 82 is higher than the height H1 from the upper surface 86a of the step 86 of the first protrusion 81 (H2> H1) It is formed.

<Operation of discharged paper>
As shown in FIG. 10B, in a state in which the leading end side of the discharge tray 23B does not bend so as to lower the discharge tray 23B in the discharge direction (this state is a normal state), the discharged sheet Aa forms the medium transport path 28. The upper surface 85a of the discharge tray 23B is moved by the conveyance force of the roller pair 48, and the leading end of the sheet Aa in the discharge direction rises on the inclined surface 86b and further runs on the inclined surface 81a of the first protrusion 81. In this case, the leading end of the sheet Aa in the discharge direction is upward. The leading end of the sheet Aa is positioned at the second projection 82, and the leading end of the sheet Aa rests in a state of being floated upward from the second projection 82.

  When the discharge of the sheet Aa is continued and the sheets Aa are stacked, as shown in FIG. 10C, the leading end side of the discharge tray 23B in the discharge direction is gradually set by the weight of the stacked sheets A. It will be in the state of bending so as to descend. The amount of deflection is in balance with the rigidity of the discharge tray 23B.

  As shown in FIG. 10C, when the paper Aa is stacked and the discharge tray 23B is bent, the height H2 of the second protrusion 82 is formed to be higher than the height H1 of the first protrusion 81. The second protrusion 82 can guide the sheet A (sheet Aa). As a result, in the case where only the first protrusion 81 is used, the leading end of the sheet A (the sheet Aa) is stacked while being lowered, but the leading edge of the sheet A (the sheet Aa) is formed by the second protrusion 82. Can be stacked in a parallel or rising state to prevent the stacked paper A (paper Aa) from sliding off.

Further, by arranging the first protrusions 81 and the second protrusions 82 respectively symmetrically to the center line C, the center line in the width direction of the sheet Aa to be discharged and the center line C of the discharge tray 23B substantially coincide with each other. By being discharged as described above, the sheet Aa can be received substantially symmetrically by the first projection 81 and the second projection 82 in the width direction, and the form of the discharged sheet Aa becomes a substantially cylindrical shape with the inner surface facing upward. The sheet can be stacked on the discharge tray 23B in a stable state in which the sheet does not fall easily.
As described above, even if the discharge tray 23B is bent, the sheets Aa to be discharged can not be stacked, so that the sheets Aa can be prevented from sliding and falling, and the sheets Aa can be stably stacked.

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

When the discharge tray 23B is bent, it is received by the second protrusions 82 provided on both sides in the width direction orthogonal to the discharge direction at the end side in the discharge direction further than the first protrusions 81. it can. Therefore, with the simple configuration of the first projection 81 and the second projection 82, the sheet Aa can be stably received by the discharge tray 23B and the sheets Aa can be stacked. Also, in the case of a sheet longer than the sheet Aa that can be received by the first protrusion 81, the second protrusion 82 can receive it. By the above, the stackability of the discharge tray 23B is improved.

  (2) According to the printer 1 of the present embodiment, the first protrusions 81 and the second protrusions 82 are respectively arranged symmetrically with respect to a center line C which divides the width direction of the discharge tray 23B into two. Thus, when the sheet Aa is discharged so that the center line in the width direction of the sheet Aa to be discharged and the center line C of the discharge tray 23B substantially coincide with each other, the sheet Aa is substantially symmetrical by the first protrusion 81 and the second protrusion 82. By receiving the sheet A, the sheet Aa has a cylindrical shape with the inner surface facing upward, and can be stacked on the discharge tray 23B in a stable state in which the sheet Aa is not easily dropped, and the stackability is improved.

  (3) According to the printer 1 of the present embodiment, the height H2 of the second protrusion 82 is the height H1 of the first protrusion 81 even when the leading end side of the discharge tray 23B is bent downward. The sheet Aa can be guided by the second projection 82 by being formed higher than the above. As a result, it is possible to prevent the leading end of the sheet Aa from being lowered and being bent, and the sheet Aa can be stably stacked on the discharge tray 23B, and the stackability is improved.
