The user can bring the fingertip into contact with the lower end of the operation unit 20 by pressing the fingertip against the flap 74 with the palm at the upper side, that is, the + Z-axis direction side, and putting the flap 74 into use. In this state, the operation unit 20 can be rotated to the front side of the printer 10 by pulling the lower end portion of the operation unit 20 toward the front side of the printer 10. That is, the operation unit 20 can be manually rotated.

  Next, the biasing means 76 that biases the cover 18 will be described with reference to FIGS. 8 to 9B. In FIG. 8, a rotation shaft 72 is provided at the end portion on the −Y axis direction side wall 69 on the + X axis direction side of the lower tray 24 so as to protrude in the + X axis direction. Biasing means 76 is attached to the rotating shaft 72. In this embodiment, the biasing means 76 is configured as a torsion spring.

  One end 76a of the urging means 76 configured as a torsion spring is engaged with the lower tray 24 (see FIG. 8). Further, the other end 76b of the urging means 76 is engaged with an engaging portion 78 provided on the cover 18, as shown in FIG. That is, the cover 18 receives a biasing force in the counterclockwise direction in FIG. 9A from the biasing means 76 in order to maintain the first posture in the state of the first posture shown in FIG. ing.

  Further, in the urging means 76, the cover 18 changes from the first posture (see FIG. 9A) to the third posture (see FIG. 9B) through the second posture (see FIG. 5). At this time, the cover 18 is biased so that the cover 18 is closed, that is, in the first posture. That is, in this embodiment, when the cover 18 is changed from the first posture, the urging force of the urging means 76 is constantly acting to return the cover 18 to the first posture.

  Next, the lock means 80 will be described with reference to FIGS. 10 to 13B. As shown in FIG. 10, at the end portion on the −Y-axis direction side of the side wall 69 on the −X-axis direction side of the lower tray 24, a rotation shaft 72 that protrudes toward the −X-axis direction side, a locking unit 80, Is provided. The locking means 80 includes an engaging portion 82 and a biasing member 84 (see FIG. 11B). The engaging portion 82 is attached to the end portion of the side wall 69 on the −Y axis direction side so as to be able to advance and retract in the X axis direction. Moreover, the engaging part 82 is provided with the engaging surface 82a mentioned later. The urging member 84 is attached between the end portion of the side wall 69 on the −Y axis direction side and the engaging portion 82, and urges the engaging portion 82 in the −X axis direction.

  As shown in FIGS. 11A and 11B, when the cover 18 is in the first posture, the engaging portion 82 is urged by the urging member 84 in the −Y-axis direction of the side wall 69. It is in a state of protruding in the −X axis direction from the end on the side. In this state, the engaging portion 82 and the cover 18 are in a disengaged state.

  12 (A), 12 (B), 13 (A), and 13 (B), the cover 18 is in the first posture with respect to the lower tray 24 (see FIG. 4). The cover 18 is rotated in the −Y-axis direction of FIG. 12A from the second position (see FIG. 5) to the third position (see FIG. 6). The operation 82 will be described.

  The cover 18 includes a guide surface 86 and a restriction surface 88 as shown in FIGS. 13 (A) and 13 (B). The guide surface 86 is provided at the end of the cover 18 on the −X axis direction side. As shown in FIG. 13A, the guide surface 86 is configured as a gentle curved surface extending from the −Y axis direction to the + Y axis direction and extending from the −X axis direction to the + X axis direction. The restriction surface 88 is formed at the + Y-axis direction side end of the cover 18 when the cover 18 is in the third posture (see FIG. 13B).

  When the cover 18 rotates from the first posture toward the second posture, the engaging portion 82 comes into contact with the guide surface 86 as shown in FIG. Further, when the cover 18 is opened in the opening direction, that is, when the cover 18 is rotated from the second position to the third position, the engaging portion 82 is guided by the guide surface 86 and resists the urging force of the urging member 84. Then, it is pushed in the + X-axis direction (see FIG. 12B).

  When the cover 18 changes to the third posture (see FIG. 13A), the contact state between the engagement portion 82 and the guide surface 86 is canceled, and the engagement that has been pushed in in the + X-axis direction. The portion 82 is projected in the −X axis direction by the biasing force of the biasing member 84. At this time, the engaging surface 82 a of the engaging portion 82 contacts the restricting surface 88. In this state, since the urging member 84 urges the engaging portion 82, the engaging surface 82 a presses the restricting surface 88, and the cover 18 changes from the third posture to the first posture or the second posture. Regulates turning to the right. That is, the cover 18 is locked (see FIG. 13B).

  When releasing the locked state of the cover 18 (FIG. 13B), the cover 18 is closed from the third posture with a force larger than the urging force of the urging member 84 (the first posture or the first posture). 2), the engaging surface 82a is pushed into the restricting surface 88 in the + X-axis direction in FIG. 13A, and the locked state is released. When the locked state is released, the urging force of the urging means 76 acts on the cover 18, so that the cover 18 is rotated in the closing direction by the urging force, and the first posture is passed through the second posture. Change to.

  Here, the relationship between the medium receiving tray 62 and the cover 18 will be organized with reference to FIGS. 14 (A) to 15 (B). In addition, illustration of the operation part 20 is abbreviate | omitted for description.

  FIG. 14A shows a state in which the medium receiving tray 62 is located at the first position Y1, that is, accommodated inside the apparatus main body 12. In this state, since the urging force of the urging means 76 acts on the cover 18, the cover 18 is closed with respect to the lower tray 24, that is, holds the first posture.

  As shown in FIG. 14B, the medium receiving tray 62 is moved from the first position Y1 (position accommodated in the apparatus main body 12) to the second position Y2 (apparatus main body 12) by a driving force from a driving source (not shown). The medium receiving tray 62 comes into contact with the cover 18 in the first posture state and moves the cover 18 in the −Y-axis direction in FIG. 13B. To turn from the first position to the second position.

  At this time, since the urging force of the urging means 76 acts on the cover 18, the cover 18 and the medium receiving tray 62 after the medium receiving tray 62 moves from the first position Y1 to the second position Y2. The contacted state, that is, the second posture is maintained (see FIGS. 2 and 3B).

  Further, since the urging force of the urging means 76 acts on the cover 18, when the medium receiving tray 62 returns from the second position Y <b> 2 to the first position Y <b> 1, the cover 18 has the second of the medium receiving tray 62. In response to the movement from the position Y2 to the first position Y1, the posture is changed from the second posture to the first posture.

  Further, the cover 18 can be further rotated in the opening direction of the cover 18 from the state changed to the second posture by the medium receiving tray 62, or the user can take the first posture. Can be changed to the third posture through the second posture (see FIG. 15A).

  When the cover 18 changes to the third posture, the cover 18 is locked by the locking means 80 and the third posture is held in the cover 18. In this embodiment, as shown in FIG. 15B, when the cover 18 is rotated clockwise by an angle θ1 from the first posture in which the cover 18 stands upright with respect to the lower tray, the second posture is obtained. Change. Further, the cover 18 changes to the third posture when the cover 18 is further rotated by an angle θ2 in the clockwise direction that is the opening direction.

■■■ About the configuration of the media tray ■■■■■■■
Next, the configuration of the medium receiving tray will be described with reference to FIGS. 16 to 18B. As shown in FIG. 3B, the medium receiving tray is provided with a mounting surface 62a on which the sheets P discharged from the upper surface are stacked.

  In addition, as shown in FIG. 16, the lower surface 62 b of the medium receiving tray 62 is provided with a plurality of ribs 90 and 90. In this embodiment, the ribs 90, 90 are provided at a distance in the X-axis direction.

  The rib 90 includes a first straight portion 90a, an intersecting portion 90b, and a second straight portion 90c. The first straight portion 90a and the second straight portion 90c extend along the Y-axis direction in FIG. 16, that is, are provided along the moving direction of the medium receiving tray 62. The intersecting portion 90b is inclined with respect to the Y-axis direction and extends in a direction intersecting the Y-axis direction, that is, a direction intersecting the moving direction of the medium receiving tray 62, and the first straight portion 90a and the second straight portion. 90c is connected. The first straight portion 90a and the second straight portion 90c are provided at a distance in the X-axis direction.

  As shown in FIGS. 17A and 17B, the medium receiving tray 62 is moved from the first position Y1 (see the two-dot chain line in FIG. 2) to the second position Y2 (see the solid line in FIG. 2). When moving to the upper end 18a of the cover. First, the upper end portion 18 a first comes into contact with the first straight portion 90 a of the rib 90. As the medium receiving tray 62 moves in the −Y-axis direction, the first linear portion 90a slides with respect to the upper end portion 18a of the cover 18 along the Y-axis direction. Here, the contact point of the upper end portion 18a of the cover 18 with the medium receiving tray 62 is in contact with the position X1 in the X-axis direction.

  Further, when the medium receiving tray 62 moves in the −Y axis direction, the intersecting portion 90b comes into contact with the upper end portion 18a of the cover 18 (see FIG. 18A). Then, as the medium receiving tray 62 moves in the −Y axis direction, the intersecting portion 90b slides with respect to the upper end portion 18a of the cover 18 along the + XY axis direction in the example shown in FIG. That is, the contact point of the upper end portion 18a of the cover 18 with the medium receiving tray 62 moves from the position X1 in the X-axis direction to the position X2.

  Further, when the medium receiving tray 62 moves in the −Y axis direction, the second linear portion 90c comes into contact with the upper end portion 18a of the cover 18 at the position X2 in the X axis direction (see FIG. 18B). As the medium receiving tray 62 moves in the −Y axis direction, the second linear portion 90c slides with respect to the upper end portion 18a of the cover 18 along the Y axis direction.

  That is, when the medium receiving tray 62 moves from the first position Y1 to the second position Y2, the contact position between the medium receiving tray 62 and the cover 18 is from the position X1 to the position X1 in the X-axis direction. It moves to the position X2 located on the + X axis direction side. In the description, the rib 90 provided on the −X axis direction side on the lower surface 62b of the medium receiving tray 62 has been described. However, in the rib 90 provided on the + X axis direction side, the extending direction of the intersecting portion 90b is −X. Since the direction is opposite to the rib 90 provided on the axial direction side, the contact position between the rib 90 provided on the + X axial direction side and the cover 18 moves from the + X axial direction side to the −X axial direction side. To do.

  Accordingly, when the medium receiving tray 62 moves between the first position Y1 and the second position Y2, the contact position between the medium receiving tray 62 and the cover 18 is moved in the Y-axis direction of the medium receiving tray 62. Accordingly, the medium receiving tray 62 is displaced in the direction (X-axis direction) intersecting the moving direction (Y-axis direction), so that the contact positions of the medium receiving tray 62 and the cover 18 are prevented from being repeatedly the same position. be able to.

  As a result, wear at the contact positions (X1, X2) of the medium receiving tray 62 and the cover 18 can be reduced. In addition, an increase in frictional force between the medium receiving tray 62 and the cover 18 due to an increase in wear at the contact position can be suppressed, and as a result, power saving of a driving source (not shown) that drives the medium receiving tray 62 can be achieved. Can do. Further, when the medium receiving tray 62 and the cover 18 move relative to each other, it is possible to reduce noise generated by an increase in the frictional force between the medium receiving tray 62 and the cover 18.

  In the medium receiving tray 62, the rib 90 is provided with an intersecting portion 90b extending in the direction (X axis direction) intersecting the moving direction (Y axis direction) of the medium receiving tray 62. The contact area of the receiving tray 62 can be reduced, and the frictional force generated between the medium receiving tray 62 and the cover 18 can be reduced. As a result, the movement of the medium receiving tray 62 between the first position and the second position can be made smooth.

  In summary, the cover 18 rotates from the first position to the second position in accordance with the movement of the medium receiving tray 62 from the first position Y1 to the second position Y2, and the medium receiving tray 62 is rotated. The cover 18 rotates from the second position to the first position in accordance with the movement from the second position Y2 to the first position Y1. Accordingly, when the medium receiving tray 62 moves from the second position Y2 to the first position Y1, that is, when the medium receiving tray 62 is accommodated in the apparatus main body 12 from a state of protruding from the front of the apparatus main body 12. The cover 18 rotates from the open state to the closed state with respect to the apparatus main body 12. That is, it is possible to prevent the cover 18 from remaining in the second posture (open state). As a result, when the medium receiving tray 62 is accommodated in the apparatus main body 12, the cover 18 returns from the second position to the first position, so that the appearance of the printer 10 is improved and the ink mist leaking from the inside of the apparatus main body 12. Can be suppressed.

  Further, when the medium receiving tray 62 is moved from the first position Y1 to the second position Y2 by the power of a driving source (not shown), the medium receiving tray 62 pushes the cover 18 to change from the first posture to the second posture. Since there is no need to provide a drive mechanism for rotating the cover 18, the configuration can be simplified and the apparatus can be downsized. Further, since the rotation of the cover 18 from the first position to the second position is interlocked with the movement of the medium receiving tray 62, the user's hand is not troubled to close the cover 18, and the operation of the printer 10 is performed. Can be improved.

  Further, since the operation unit 20 is arranged so as to block the movement path of the medium receiving tray 62 when the operation unit 20 is in the closed posture, the operation unit 20 does not block the movement path of the medium receiving tray 62 when the operation unit 20 is closed. The dimension in the Z-axis direction can be made smaller than the case of disposing in FIG. Therefore, the height dimension of the printer 10 can be suppressed.

  Further, when the operation unit 20 is rotated by receiving power from a drive source (not shown), the medium receiving tray 62 and the cover 18 operate in conjunction with the operation unit 20, so that the user can operate the operation unit 20, the medium receiving tray 62, and the like. It is not necessary to operate the cover 18 separately, and the operability of the printer 10 can be improved.

  Further, since the cover 18 can be rotated from the second posture to the third posture which is the posture in the opening direction, the user can rotate the cover 18 to the third posture, thereby The paper P can be supplied from the (−Y-axis direction side) to the lower tray 24. Thus, the user does not have to remove the lower tray 24 from the apparatus main body 12 and supply the paper P, so that the workability of the printer 10 can be improved.

  Further, since the cover 18 is biased in the closing direction at least between the first posture and the second posture, the medium receiving tray 62 is moved from the second position Y2 to the first position Y1. The cover 18 returns from the second posture to the first posture in conjunction with certainty. Therefore, it is possible to prevent the cover 18 from remaining in the second posture (open state), so that the aesthetics of the printer 10 can be improved and ink mist leaking from the inside of the apparatus main body 12 can be suppressed.

  In addition, since the cover 18 includes the lock unit 80 that holds the cover 18 in the third posture, the cover 18 can be reliably held in the third posture. Accordingly, since the cover 18 does not change to the first posture or the second posture while the user is supplying the paper P to the lower tray 24, the user's work is not hindered and the workability of the printer 10 is improved. Can be improved. Furthermore, the locking means 80 includes the engaging portion 82 that engages with the cover 18 in the process of switching the cover 18 from the second position to the third position, so that the cover 18 is reliably brought into the third position. Can be held.

■■■ About the second embodiment ■■■■■■■
Referring to FIGS. 19A and 19B, an urging means 92 according to a second embodiment of the present invention is shown. The biasing means 92 is different from the first embodiment in that it is constituted by a leaf spring.

  As shown in FIG. 19A, the urging means 92 is constituted by a leaf spring. The cover 94 is provided with a cam 96 and an engagement surface 98. The cover 94 is moved from the first posture (see FIG. 19A) to the third posture (FIG. 19B) through the second posture (not shown) in which the cover 94 is inclined with respect to the lower tray 24. )), The urging means 92 engages with the cam 96 of the cover 94 and is bent in the + Y-axis direction along the shape of the cam 96. As a result, a biasing force is generated in the biasing means 92 to hold the cover 94 in the first posture.

  That is, the cover 94 receives an urging force to close the cover 94 at least when the cover 94 changes from the first position to the second position. Further, when the cover 94 is rotated clockwise in FIG. 19B to change from the second posture to the third posture, the urging means 92 is guided by the cam 96 and engaged with the engagement surface 98. It becomes a joint state. In this state, since the deflection in the + Y-axis direction is eliminated in the urging means 92, the urging force for returning the cover 94 to the first posture has disappeared. That is, in the process in which the cover 94 changes from the second posture to the third posture, the urging force of the urging means 92 that attempts to close the cover 94 that acts on the received cover 94 disappears.

  Further, when the cover 94 is in the third posture, the urging means 92 and the engaging surface 98 are in an engaged state. Here, when the cover 94 is returned from the third posture to the first posture through the second posture, the biasing means 92 bends in the + Y-axis direction. As a result, a biasing force is generated in the biasing means 92 to hold the cover 94 in the third posture. Therefore, the cover 94 maintains the third posture.

  To summarize the above description, the cover 94 is biased in the closing direction, that is, the first posture side at least between the first posture and the second posture, and the cover 94 is moved from the second posture to the first posture. In the process of changing to the posture 3, the urging force in the closing direction applied to the cover 94 disappears. Accordingly, since the cover 94 is biased in the closing direction between the first posture and the second posture, according to the movement of the medium receiving tray 62 from the second position Y2 to the first position Y1. Since the cover 94 returns from the second posture to the first posture, the cover 94 can be prevented from remaining in the second posture (open state). As a result, the aesthetics of the printer 10 can be improved and ink mist leaking from the inside of the apparatus main body can be suppressed.

  Further, since the urging force applied to the cover 94 in the closing direction (first posture) disappears in the process of changing from the second posture to the third posture, the cover 94 has changed to the third posture. Thereafter, the third posture is held. Here, for example, when the user supplies the paper P to the lower tray 24, the cover 94 holds the third posture, so that the cover 94 changes from the third posture to the first posture or the second posture. Therefore, the front of the lower tray 24 is prevented from being blocked, so that it is possible to reduce the possibility of hindering the work of supplying the paper P to the lower tray 24.

<<< Modified Example of Second Embodiment >>>
In the present embodiment, when the cover 94 is in the third posture, the biasing means 92 holds the third posture. Therefore, the locking means for holding the cover 18 in the third posture on the lower tray 24. 80 may not be provided, but the lock unit 80 may be provided in the lower tray 24.

■■■ About the third example ■■■■■■■
Referring to FIGS. 20 (A), 20 (B) and 21, there is shown a biasing means 100 according to a third embodiment of the present invention. The biasing means 100 is different from the first embodiment in that it is constituted by a tension spring.

  In this embodiment, the biasing means 100 is configured as a tension spring, and as shown in FIG. 20A, one end 100a of the biasing means 100 is connected to the lower tray 24, and the other end 100b is connected to the cover 18. ing. As shown in FIGS. 20A and 20B, the urging means 100 is configured such that the cover 18 is in the process of changing from the first posture to the second posture and the cover 18 is in the lower tray in the second posture. The urging force is applied to the cover 18 so as to rotate in the closing direction with respect to 24, that is, in the clockwise direction in FIG.

  On the other hand, when the cover 18 is changed from the second posture (see FIG. 20B) to the third posture (see FIG. 21), the direction of the urging force of the urging means 100 closes the cover 18 (FIG. 20). It changes from the clockwise direction in (B) to the opening direction (counterclockwise direction in FIG. 21).

  Therefore, the cover 18 is held in the third posture by the biasing force of the biasing means 100 in the direction of opening the cover 18. Thus, as an example, when the user supplies the paper P to the lower tray 24, the cover 18 holds the third posture, so that the cover 18 rotates toward the lower tray 24 and moves forward of the lower tray 24. Therefore, it is possible to reduce the possibility of obstructing the operation of supplying the paper P to the lower tray 24.

<<<< Modification of the third embodiment >>>>
In this embodiment, since the biasing means 100 is configured to hold the cover 18 in the third posture, the lock means 80 for holding the cover 18 in the third posture may not be provided on the lower tray 24. It is good also as a structure which provides the locking means 80 in the lower stage tray 24. FIG.

■■■ About the fourth example ■■■■■■■
22A and 22B, a holding unit 102 according to a fourth embodiment of the present invention is shown. The holding means 102 differs from that of the first embodiment in that it is composed of a magnet.

  Referring to FIG. 22A, the magnetic member 104 is attached to the lower surface 62 b of the medium receiving tray 62. On the other hand, an upper end portion 18a of the cover 18 is provided with a holding means 102 made of a magnet. As shown in FIG. 22A, when the medium receiving tray 62 is located at the first position Y1, the cover 18 takes the first posture, and the holding means 102 is attached to the magnetic member 104 attached to the medium receiving tray 62. It is in a state of being attracted by magnetic force.

  As shown in FIG. 22B, when the medium receiving tray 62 moves from the first position Y1 (see the two-dot chain line portion in FIG. 2) toward the second position Y2 (see the solid line portion in FIG. 2), The cover 18 is in the second posture in a state where it is attracted to the magnetic member 104 by the magnetic force of the holding means 102. The medium receiving tray 62 slides with respect to the cover 18 while the cover 18 holds the second posture by the holding means 102. Even after the medium receiving tray 62 has moved to the second position, the cover 18 holds the state of being attracted to the medium receiving tray 62 by the holding means 102 and holds the second posture.

  Further, when the medium receiving tray 62 moves from the second position Y2 to the first position Y1, the cover 18 changes from the second position to the first position in conjunction with the movement of the medium receiving tray 62.

  Further, in this embodiment, when the cover 18 is rotated in the clockwise direction in FIG. 22B from the second posture (see FIG. 22B), the magnetic force of the holding means 102 with respect to the magnetic member 104 is increased.
