  According to the technique of Patent Document 1, it is not necessary for the user to adjust the position of the positioning portion (guide bar 35) when receiving a recording medium having a different length in the second direction in the recording medium receiving tray. Can be reduced. However, there may be a case where a gap is generated between the side of the tag 18 (recording medium) and the guide bar 35 in a state where the tip of the tag 18 is in contact with the stopper surface 24. In this case, the recording medium cannot be properly positioned in the second direction, and the position of the recording medium in the second direction varies.

  An object of the present invention is to eliminate the need for the user to adjust the position of the positioning portion when receiving a recording medium having a different length in the second direction on the recording medium receiving tray, and to adjust the position of the recording medium in the second direction. An object of the present invention is to provide a recording medium receiving tray capable of suppressing variations.

  The recording medium receiving tray according to the present invention is a recording medium receiving tray for receiving the recording medium discharged in the first direction from the discharge port of the recording apparatus so as to receive the recording medium discharged from the discharge port. A receiving member configured to have a support surface for supporting a recording medium, and a receiving member attached to the receiving member so as to protrude from the support surface. A projecting member configured to contact one end of a second direction orthogonal to the first direction and parallel to the support surface, and a recording medium attached to the receiving member and received by the receiving member And a positioning portion disposed at a position corresponding to the other end of the second direction, the positioning portion having a first contact portion and a second contact portion that contact a recording medium, and the second In the direction It is configured to be able to take a protruding position protruding from the support surface and an immersion position immersed in the receiving member so as not to protrude from the support surface by rotating around the existing first axis, and By rotating around a second axis extending in a third direction orthogonal to the first direction and the second direction, the second contact portion is more than the first contact portion with respect to the second direction. A rotating member configured to be able to take a proximity position close to the projecting member and a separation position in which the second contact portion is separated from the projecting member with respect to the second direction as compared to when the projecting member is in the proximity position; A first urging member that urges the rotating member toward the projecting position from the immersion position; and a second urging member that urges the rotating member toward the proximity position from the separated position. And a biasing member.

  According to the present invention, the rotating member can be moved in and out of the receiving member, and when the length of the received recording medium in the second direction is the corresponding length of the rotating member, When the length of the received recording medium in the second direction is longer than the corresponding length of the rotating member while being held at the protruding position against the pressing force from the recording medium moving in one direction By rotating around the first axis by the pressing force from the recording medium moving in the first direction, the recording medium moves from the protruding position to the immersive position. This eliminates the need for the user to adjust the position of the positioning portion when receiving recording media having different lengths in the second direction in the recording medium receiving tray. In addition, when the length of the received recording medium in the second direction is the corresponding length of the rotating member, the rotating member receives the second force by the pressing force from the recording medium moving in the first direction. By rotating around the axis line, it moves from the proximity position to the separation position. Here, the rotation member is urged by the second urging member so as to go from the separation position to the proximity position. Therefore, the recording medium receives a force in the direction toward the projecting member with respect to the second direction from the rotating member, and one end contacts the projecting member. Accordingly, the recording medium is appropriately positioned in the second direction by the positioning portion and the protruding member, and variation in the position of the recording medium in the second direction can be suppressed.

  The positioning portion further includes a first member configured to rotate about the first axis, and the rotation member rotates about the second axis with respect to the first member. It may be connected as possible. According to this configuration, the rotation member is attached to the first axis and the second axis by attaching the rotation member to be rotatable about the second axis with respect to the first member rotating about the first axis. The configuration of rotating around the two axes with the axis can be realized relatively easily.

  The positioning portion further includes a second member configured to rotate about the second axis, and the rotation member rotates about the first axis with respect to the second member. It may be connected as possible. According to this configuration, the rotating member is attached to the first axis and the second axis by attaching the rotating member to be rotatable about the first axis with respect to the second member rotating about the second axis. The configuration of rotating around the two axes with the axis can be realized relatively easily.

  The biasing force of the first biasing member may be greater than the biasing force of the second biasing member. According to this configuration, the recording medium can be reliably positioned in the second direction. Specifically, if the rotating member moves from the protruding position to the immersive position before moving from the proximity position to the separation position, the recording medium cannot be positioned in the second direction. When the rotating member should move from the protruding position to the immersive position and when the rotating member should move from the close position to the separated position due to the size relationship of the length in the second direction of the recording medium, the former is better than the latter. However, the pressing force from the recording medium acting on the rotating member tends to be large. The above configuration is in view of this tendency, and by setting the urging force as described above, the rotation member is prevented from moving from the protruding position to the immersive position before moving from the close position to the separated position. Therefore, the recording medium can be reliably positioned in the second direction.

  When the rotating member is in the proximity position, the first contact portion is disposed at a position overlapping the second axis with respect to the second direction, and the second contact portion is related to the second direction. You may arrange | position in the position which does not overlap with a 2nd axis line. According to this configuration, when the tip of the recording medium comes into contact with the first contact portion, a moment around the second axis is unlikely to occur, but when the tip of the recording medium comes into contact with the second contact portion. A moment around the second axis is likely to occur. Therefore, the recording medium can be reliably positioned in the second direction. Specifically, when the leading end of the recording medium whose length in the second direction is the corresponding length of the rotating member contacts the second contact portion, a relatively large moment about the second axis is applied. Can be generated. Accordingly, the rotating member rotates about the second axis and moves from the close position to the separated position, and the recording medium can be reliably positioned in the second direction.

  When the rotating member is in the proximity position, the second contact portion may be disposed downstream of the first contact portion in the first direction. According to this configuration, depending on the length of the recording medium to be received in the second direction, the rotation member is appropriately positioned in either the protruding position or the immersive position, and in the proximity position or the separation position. The correct position. Specifically, when a recording medium whose length in the second direction is the corresponding length of the rotating member is received, as described above, when the leading end of the recording medium comes into contact with the second contact portion In addition, a moment about the second axis is generated, and the rotating member rotates about the second axis and moves from the close position to the separated position, thereby ensuring the positioning of the recording medium in the second direction. It can be carried out. On the other hand, when a recording medium whose length in the second direction is longer than the corresponding length of the rotating member is received, the recording medium is placed on the first contact portion on the upstream side in the first direction with respect to the second contact portion. When the tip of the first contacts first, the rotating member rotates about the first axis and moves from the protruding position to the immersive position.

  When the rotating member is in the proximity position, the second contact portion may be disposed at a position overlapping the second axis with respect to the first direction. According to this configuration, the loss of the pressing force from the recording medium acting on the rotating member when the rotating member starts to rotate about the second axis (that is, starts to move from the close position to the separated position). Is suppressed, and the pressing force acts efficiently on the rotating member. Accordingly, the rotation member can be smoothly moved from the close position to the separated position, and the recording medium can be reliably positioned in the second direction.

  The recording medium receiving tray according to the present invention is configured to restrict the rotation of the rotating member about the first axis when the rotating member rotates about the second axis. Further, a restriction unit may be further provided. According to this configuration, the recording medium can be reliably positioned in the second direction.

  The restricting portion includes a first restricting portion provided on the rotating member and a second restricting portion provided on the receiving member, and when the rotating member is in the protruding position, the second restricting portion is provided. And the rotation member is located outside the movement range of the first restricting portion when the rotation member moves from the protruding position to the immersion position, and the rotation member rotates around the second axis from the proximity position. When moved, the second restricting portion may be located within the movement range. According to the said structure, control and cancellation | release of rotation can be performed appropriately.

  The first restricting portion includes a convex portion that protrudes upstream in the first direction when the turning member in the turning member is in the protruding position, and the second restricting portion is in the receiving member. A wall defining a hole formed in the support surface may be included. According to the said structure, the structure of a control part can be simplified.

  The recording medium receiving tray according to the present invention includes a plurality of recording medium receiving trays arranged at different positions with respect to the second direction so as to correspond to the other ends of the plurality of recording media having different lengths in the second direction. The positioning part may be provided. According to this configuration, since the plurality of rotating members are arranged at different positions with respect to the second direction, the rotation held at the protruding position according to the length of the received recording medium in the second direction. The position of the member is different with respect to the second direction. Accordingly, various recording media having different lengths in the second direction can be appropriately positioned.

  The plurality of positioning portions may be arranged at different positions with respect to the first direction. When the recording medium moving in the first direction is simultaneously contacted with the plurality of rotating members, the recording medium is prevented from moving by receiving the resistance force from the plurality of rotating members at a time and is not received at an appropriate position. Cases can arise. The above configuration has been made in view of this problem. The recording medium moving in the first direction is not in contact with the plurality of rotating members at the same time, and the resistance force from the plurality of rotating members is dispersed over time. By receiving it, the above problem can be reduced.

  The plurality of first urging members may have a smaller urging force as the positioning portion is arranged on the downstream side in the first direction. As the recording medium moves in the first direction when it is received, the waist of the tip portion tends to become weaker. The above configuration is in consideration of this tendency. By setting the urging force as described above, the waist of the recording medium is weak at the downstream side in the first direction, and the pressing force from the recording medium is reduced. Even if it is small, the rotating member can reliably rotate about the first axis and move from the protruding position to the immersive position.

  Each of the plurality of rotating members may be disposed at a position corresponding to the center of the first direction of the recording medium in which the length in the second direction is the corresponding length of the rotating member. According to this configuration, the recording medium can be reliably positioned in the second direction.

  According to the present invention, when a recording medium having a different length in the second direction is received by the recording medium receiving tray, the user does not need to adjust the position of the positioning portion, and the position of the recording medium in the second direction can be reduced. Variations can be suppressed.

It includes two projecting members 42b and one positioning portion 43b, and two projecting members 42c and one positioning portion 43c corresponding to a large-size sheet Pc. The protruding members 42 a to 42 c and the positioning portions 43 a to 43 c are attached to the receiving member 41.

  The receiving member 41 is a rectangular plate member configured to receive the paper P discharged from the discharge port 1b, and includes a support surface 41a that supports the paper P and a side wall that defines the discharge port 1b. 41b.

  Hereinafter, the direction in which the paper P is discharged from the discharge port 1b is the first direction X, and the directions orthogonal to the first direction X and parallel to the support surface 41a are the second direction Y, the first direction X, and the second direction Y. The orthogonal direction is referred to as a third direction Z.

  The sheets Pa to Pc are different from each other in the length in the first direction X and the length in the second direction Y. Regarding the first direction X, the paper Pb is longer than the paper Pa, and the paper Pc is longer than the paper Pb. Regarding the second direction Y, the paper Pb is longer than the paper Pa, and the paper Pc is longer than the paper Pb. The sheets Pa to Pc are discharged so that the center in the second direction Y substantially coincides with the center in the second direction Y of the support surface 41a. Further, the rear end Px2 of the sheet P received in the receiving tray 4 in the first direction X contacts the surface of the side wall 41b on the support surface 41a side.

  The side wall 41b protrudes upward from the upstream end portion of the receiving member 41 in the first direction X. The upper end of the side wall 41b defines the discharge port 1b.

  The support surface 41a extends substantially parallel to the first direction X, and intersects the horizontal plane so as to be upward toward the downstream side in the first direction X (see FIG. 1). That is, the first direction X intersects the horizontal plane so as to be upward toward the downstream side.

  As shown in FIGS. 3 to 6, the support surface 41 a has six holes 41 y for attaching the protruding members 42 a to 42 c to the receiving member 41 and one hole for attaching the positioning portions 43 a and 43 b to the receiving member 41. 41za and one hole 41zc for attaching the positioning part 43c to the receiving member 41 are formed.

  Two projecting members 42a are arranged at positions corresponding to one end Py1 in the second direction Y of the paper Pa. A positioning portion 43a is disposed at a position corresponding to the other end Py2 in the second direction Y of the paper Pa. The two projecting members 42a are arranged at different positions with respect to the first direction X, and are arranged at positions spaced apart from each other by a predetermined distance from the upstream end and the downstream end in the first direction X of the one end Py1 of the paper Pa. The

  Two protruding members 42b are arranged at a position corresponding to one end Py1 in the second direction Y of the paper Pb. A positioning portion 43b is disposed at a position corresponding to the other end Py2 in the second direction Y of the paper Pb. The two projecting members 42b are disposed at different positions with respect to the first direction X, and are disposed at positions spaced apart from each other by a predetermined distance from the upstream end and the downstream end in the first direction X of the one end Py1 of the paper Pb. The

  Two protruding members 42c are arranged at a position corresponding to one end Py1 in the second direction Y of the paper Pc. A positioning portion 43c is disposed at a position corresponding to the other end Py2 in the second direction Y of the paper Pc. The two projecting members 42c are arranged at different positions with respect to the first direction X, and are arranged at positions spaced apart from each other by a predetermined distance from the upstream end and the downstream end in the first direction X of one end Py1 of the paper Pc. The

  The positioning portions 43a to 43c are arranged at different positions with respect to the first direction X and the second direction Y so as to correspond to the center in the first direction X of the other ends Py2 of the papers Pa to Pc, respectively.

  Each positioning part 43a-43c contains the rotation member 44, the 1st member 48, and the springs 46 and 47, as shown in FIG.

  The first member 48 is configured to rotate around a first axis Y1 extending in the second direction Y, and includes a shaft portion 48a extending in the second direction Y, and a shaft portion from the shaft portion 48a. An extending portion 48b extending in a direction orthogonal to 48a and an extending portion 48c extending from the shaft portion 48a in a direction orthogonal to the shaft portion 48a and the extending portion 48b are included. A concave portion 48d is formed on the surface of the shaft portion 48a on the side where the extending portion 48b extends.

  The rotation member 44 is connected to the first member 48 so as to be rotatable about a second axis Z2 extending in the third direction Z, and a shaft portion 44d extending in the third direction Z is provided. And the extending portion 44b extending in the tangential direction of the cylindrical portion 44a over the entire height direction region of the cylindrical portion 44a from the outer peripheral portion of the cylindrical portion 44a. The shaft portion 44d is provided on the bottom surface of the cylindrical portion 44a and is inserted into the recess 48d. The side surface of the cylindrical portion 44a is supported by the extending portion 48b over the entire region in the height direction of the cylindrical portion 44a. A part of the outer peripheral surface of the cylindrical portion 44a (specifically, the portion opposite to the portion where the extending portion 44b extends) constitutes a first contact portion 44ax that contacts the paper P. The distal end portion of the extending portion 44b protrudes in a direction perpendicular to the extending direction of the extending portion 44b and approaches the cylindrical portion 44a, and has a thickness larger than that of the other portions. The end surface of the protruding tip portion constitutes a second contact portion 44bx that contacts the paper P. When the rotating member 44 is in the projecting position and the close position, the outer surface between the first contact portion 44ax and the second contact portion 44bx in the extension portion 44b is formed between the first contact portion 44ax and the second contact portion 44bx. It is located on the downstream side in the first direction with respect to the virtual straight line connecting the two. Thereby, the front end Px1 of the paper P can be prevented from coming into contact with the outer surface of the extending portion 44b other than the first contact portion 44ax and the second contact portion 44bx, and the pressing force received from the paper P by the rotating member 44 Can be determined on the first contact portion 44ax or the second contact portion 44bx.

  The rotating member 44 rotates about the first axis Y1 as the first member 48 rotates about the first axis Y1, thereby protruding from the support surface 41a (in FIG. 9). The rotation member 44 of the positioning portions 43b and 43c), and an immersion position (see FIG. 5B, the rotation member 44 of the positioning portion 43a) immersed in the receiving member 41 so as not to protrude from the support surface 41a. It is configured to be able to take. 7A to 7D show a state in which the rotating member 44 of the positioning portion 43a moves from the protruding position to the immersive position. Further, the rotation member 44 rotates about the second axis Z2 with respect to the first member 48, whereby the second contact portion 44bx in the second direction Y is more protruded than the first contact portion 44ax. The second contact portion 44bx is separated from the projecting members 42a to 42c with respect to the proximity position close to 42c (see the rotating member 44 of the positioning portions 43a to 43c in FIG. 3) and the second direction Y as compared with the proximity position. It is configured to be able to take a separation position (see the rotation member 44 of the positioning portion 43a in FIG. 4). 7A to 7D show a state where the rotating member 44 of the positioning portion 43b moves from the close position to the separated position.

  As shown for the positioning portion 43a in FIG. 3, when the rotating member 44 is in the proximity position, the first contact portion 44ax is disposed at a position overlapping the second axis Z2 in the second direction Y, and the second contact The part 44bx is disposed at a position that does not overlap the second axis Z2 in the second direction Y. At this time, the second contact portion 44bx is disposed downstream of the first contact portion 44ax in the first direction X and overlaps with the second axis Z2 with respect to the first direction X. This positional relationship is also established in the other positioning portions 43b and 43c.

  With respect to the positioning portion 43a, when the rotation member 44 is in the projecting position and the close position, when the paper Pa corresponding to the positioning portion 43a is discharged from the discharge port 1b, the leading end Px1 of the paper Pa becomes the second contact portion 44bx The rotating member 44 is disposed at a position where it contacts the first contact portion 44ax but does not contact the first contact portion 44ax. Further, regarding the positioning portion 43a, when the rotating member 44 is in the protruding position and the close position, the sheets Pb and Pc having a length in the second direction Y longer than the sheet Pa corresponding to the positioning section 43a are discharged from the discharge port 1b. In this case, the rotation member 44 is arranged at a position where the leading end Px1 of the paper Pb, Pc comes into contact with the first contact portion 44ax. Similarly, for the positioning portions 43b and 43c, in the case of the corresponding size paper P, the front end Px1 of the paper P contacts the second contact portion 44bx but does not contact the first contact portion 44ax. In the case of the paper P whose length in the second direction Y is longer than the size to be rotated, the rotating member 44 is disposed at a position where the leading end Px1 of the paper P contacts the first contact portion 44ax.

  The spring 46 is attached to the receiving member 41, a coil-shaped portion wound around the shaft portion 48 a, one end attached to the surface of the extending portion 48 b opposite to the surface supporting the side surface of the cylindrical portion 44 a, and The other end. The spring 46 biases the rotating member 44 so as to go from the retracted position to the protruding position. That is, the spring 46 corresponds to the first biasing member of the present invention. For each positioning portion 43a to 43c, the spring 46 resists the pressing force that the rotating member 44 receives from the paper Pa to Pc even if the leading end Px1 of the corresponding paper Pa to Pc contacts the second contact portion 44bx. The biasing force is set so as to be held at the protruding position. Further, when the leading end Px1 of the paper P whose length in the second direction Y is longer than the corresponding paper Pa to Pc is in contact with the first contact portion 44ax, the spring 46 is rotated about the positioning members 43a to 43c. Is set to an urging force that is moved from the protruding position to the immersive position by the pressing force received from the paper P.

  The spring 47 includes a coil-shaped portion wound around the shaft portion 44d, one end attached to the tip of the extending portion 48c, and the other end attached to the lower end of the extending portion 44b. The spring 47 biases the rotating member 44 so as to go from the separation position to the proximity position. That is, the spring 47 corresponds to the second urging member of the present invention. For each positioning portion 43a to 43c, the spring 47 is separated from the proximity position by the pressing force that the rotating member 44 receives from the paper Pa to Pc when the tip Px1 of the corresponding paper Pa to Pc contacts the second contact portion 44bx. The energizing force is set so as to be moved to

  In each of the positioning portions 43 a to 43 c, the urging force of the spring 46 is larger than the urging force of the spring 47. Further, the biasing force of the spring 46 is smaller as the positioning portions 43a to 43c are arranged on the downstream side in the first direction X. That is, the biasing force of the spring 46 of the positioning portion 43b is smaller than the biasing force of the spring 46 of the positioning portion 43a. The biasing force of the spring 46 of the positioning portion 43c is smaller than the biasing force of the spring 46 of the positioning portion 43b.

  Although the detailed description of the projecting members 42a to 42c is omitted, the projecting position and the immersive position are determined by pivoting about the axis extending in the second direction Y, similarly to the pivoting member 44. Configured to get.

  In FIG. 3, all of the projecting members 42 a to 42 c and the rotating members 44 of the positioning portions 43 a to 43 c are in the projecting position. Further, all of the rotation members 44 of the positioning portions 43a to 43c are in the proximity positions.

  In FIG. 4, all of the protruding members 42 a to 42 c and the rotating members 44 of the positioning portions 43 a to 43 c are in the protruding position. Further, the rotation member 44 of the positioning portion 43a corresponding to the paper Pa is in the separation position, and the rotation member 44 of the positioning portions 43b and 43c not corresponding to the paper Pa is in the proximity position. At this time, one end Py1 of the paper Pa is in contact with the two protruding members 42a, and the other end Py2 of the paper Pa is in contact with the second contact portion 44bx of the rotating member 44 of the positioning portion 43a.

  In FIG. 5, the two protruding members 42 a and the rotating member 44 of the positioning portion 43 a are in the immersive position (not shown because they are below the paper Pb), and the protruding members 42 b and 42 c and the positioning portions 43 b and 43 c. The rotating member 44 is in the protruding position. Further, the rotation member 44 of the positioning portion 43b corresponding to the paper Pb is in the separation position, and the rotation member 44 of the positioning portion 43c not corresponding to the paper Pb is in the proximity position. At this time, one end Py1 of the paper Pb is in contact with the two protruding members 42b, and the other end Py2 of the paper Pb is in contact with the second contact portion 44bx of the rotating member 44 of the positioning portion 43b.

  In FIG. 6, the protruding members 42 a and 42 b and the rotating member 44 of the positioning portions 43 a and 43 b are in the immersive position (not shown because they are below the paper Pc), the two protruding members 42 c and the positioning portion 43 c. The rotating member 44 is in the protruding position. Further, the rotation member 44 of the positioning portion 43c corresponding to the paper Pc is in the separation position. At this time, one end Py1 of the paper Pc is in contact with the two protruding members 42c, and the other end Py2 of the paper Pc is in contact with the second contact portion 44bx of the rotating member 44 of the positioning portion 43c.

  Here, the operations of the protruding members 42a to 42c and the positioning portions 43a to 43c when the paper Pb is received will be described with reference to FIG.

  First, the sheet Pb is discharged from the discharge port 1b, and the leading end Px1 of the sheet Pb in the first direction X comes into contact with one of the two protruding members 42a on the upstream side in the first direction X. It contacts the first contact portion 44ax of the rotating member 44 (see FIGS. 7A and 7B). When the paper Pb further moves in the first direction X, the rotating member 44 of the positioning portion 43a rotates about the first axis Y1 by the pressing force from the paper Pb moving in the first direction X, and the protruding position To the immersive position (see FIGS. 7B and 7C). At this time, one of the two projecting members 42a on the upstream side in the first direction X is similarly centered on the axis along the second direction Y by the pressing force from the paper Pb moving in the first direction X. Rotates and moves from the protruding position to the immersive position.

  When the paper Pb further moves in the first direction X, the leading end Px1 is one of the two protruding members 42a on the downstream side in the first direction X and the second contact portion 44bx of the rotating member 44 of the positioning portion 43b. (Refer to FIG. 7C). When the paper Pb further moves in the first direction X, the rotating member 44 of the positioning portion 43b is held at the protruding position against the pressing force from the paper Pb moving in the first direction X, and the pressing force causes Then, it rotates around the second axis Z2 and moves from the proximity position to the separation position (see FIGS. 7C and 7D). At this time, one of the two projecting members 42a on the downstream side in the first direction X is rotated about the axis along the second direction Y by the pressing force from the paper Pb moving in the first direction X. And move from the protruding position to the immersive position. At this time, the rotation member 44 of the positioning portion 43b is urged by the spring 47 so as to move from the separation position to the proximity position, so that the sheet Pb is directed to the two protruding members 42b with respect to the second direction Y. The one end Py1 is in contact with the two projecting members 42b. Thereby, the paper Pb is appropriately positioned in the second direction Y by the positioning portion 43b and the two protruding members 42b.

  The receiving tray 4 rotates with respect to the positioning portions 43a to 43c around the first axis Y1 of the rotating member 44 when the rotating member 44 rotates about the second axis Z2. It has the control part 49 comprised so that control may be controlled (refer FIG. 8). The restricting portion 49 includes a convex portion 44 p provided on the rotating member 44 and a wall 41 x provided on the receiving member 41. The convex portion 44p corresponds to the first restricting portion of the present invention. The wall 41x corresponds to the second restricting portion of the present invention. The convex portion 44p is provided in the vicinity of the bottom portion of the outer peripheral surface constituting the first contact portion 44ax in the cylindrical portion 44a (see FIG. 10B), and the first portion when the rotating member 44 is in the protruding position. It protrudes upstream in the direction X (see the rotating member 44 of the positioning portion 43c in FIG. 8). The wall 41x is a part that defines the holes 41za and 41zc in the receiving member 41. When the rotating member 44 is in the protruding position, the wall 41x is located outside the movement range of the convex portion 44p when the rotating member 44 moves from the protruding position to the immersive position (in FIG. 8, the positioning portion 43c). Of the rotation member 44). At this time, the rotation of the rotating member 44 around the first axis Y1 is not restricted, and the rotating member 44 can move from the protruding position to the immersive position. On the other hand, when the rotation member 44 is rotated around the second axis Z2 from the proximity position, the wall 41x is positioned within the movement range (see the rotation member 44 of the positioning portion 43b in FIG. 8). At this time, the rotation of the rotating member 44 around the first axis Y1 is restricted, and the rotating member 44 cannot move from the protruding position to the immersive position.

  As described above, according to the present embodiment, the rotating member 44 can protrude and retract with respect to the receiving member 41, and the length of the received paper P in the second direction Y is the rotating member 44. , The length of the received paper P in the second direction Y is held at the protruding position against the pressing force from the paper P moving in the first direction X. When the rotation member 44 is longer than the corresponding length, it is moved from the protruding position to the immersive position by rotating around the first axis Y1 by the pressing force from the paper P moving in the first direction X. (Refer to FIGS. 3 to 6 and FIG. 7). This eliminates the need for the user to adjust the positions of the positioning portions 43a to 43c when receiving the sheets Pa to Pc having different lengths in the second direction Y in the receiving tray 4. Further, the rotating member 44 is pushed by the sheet P moving in the first direction X when the length of the received sheet P in the second direction Y is the corresponding length of the rotating member 44. By rotating about the second axis Z2 by the pressure, it moves from the proximity position to the separation position (see FIGS. 3 to 6 and FIG. 7). Here, the rotation member 44 is biased by the spring 47 so as to go from the separation position to the proximity position. Therefore, the sheet P receives a force in the direction toward the protruding members 42a to 42c with respect to the second direction Y from the rotating member 44, and the one end Py1 comes into contact with the corresponding protruding members 42a to 42c. As a result, the paper P is appropriately positioned in the second direction Y by the positioning portions 43a to 43c and the protruding members 42a to 42c corresponding to the size of the paper P, and variation in the position of the paper P in the second direction Y is suppressed. can do.

  The rotation member 44 is attached to the first member 48 that rotates about the first axis Y1 so as to be rotatable about the second axis Z2. Thereby, the structure that the rotation member 44 rotates centering on the two axes of the first axis Y1 and the second axis Z2 can be realized relatively easily.

  In each of the positioning portions 43 a to 43 c, the urging force of the spring 46 is larger than the urging force of the spring 47. According to this configuration, the paper P can be reliably positioned in the second direction Y. Specifically, if the rotating member 44 moves from the protruding position to the immersive position before moving from the close position to the separated position, the sheet P cannot be positioned in the second direction Y. The former when the rotating member 44 should move from the protruding position to the immersive position and when the rotating member 44 should move from the close position to the separated position due to the size relationship of the length in the second direction Y of the paper P, etc. However, the pressing force from the paper P acting on the rotating member 44 tends to be larger than the latter. That is, when the rotating member 44 should move from the protruding position to the immersive position, the length of the paper P in the second direction Y is longer than when the rotating member 44 should move from the close position to the separated position. In general, the paper P having a long length in the second direction Y is often heavier than the paper P having a short length in the second direction Y. Therefore, when the rotating member 44 should move from the protruding position to the immersive position, the pressing force from the paper P acting on the rotating member 44 than when the rotating member 44 should move from the close position to the separated position. Is considered large. The above configuration is in view of this tendency. By setting the biasing force as described above, the rotating member 44 moves from the protruding position to the immersive position before moving from the close position to the separated position. Therefore, it is possible to reliably position the paper P in the second direction Y.

  When the rotating member 44 is in the proximity position, the first contact portion 44ax is disposed at a position overlapping the second axis Z2 with respect to the second direction Y, and the second contact portion 44bx is second with respect to the second direction Y. It arrange | positions in the position which does not overlap with the axis line Z2 (refer the positioning part 43a of FIG. 3). According to this configuration, when the leading end Px1 of the paper P is in contact with the first contact portion 44ax, a moment around the second axis Z2 is unlikely to occur, but the leading end Px1 of the paper P is in contact with the second contact portion 44bx. In the case of contact, a moment around the second axis Z2 is likely to occur. Therefore, the positioning of the paper P in the second direction Y can be reliably performed. Specifically, when the leading end Px1 of the paper P whose length in the second direction Y is the corresponding length of the rotating member 44 comes into contact with the second contact portion 44bx, the second axis Y2 is set as the center. A relatively large moment can be generated. Thereby, the rotation member 44 rotates about the second axis Z2 and moves from the proximity position to the separation position, and the sheet P can be reliably positioned in the second direction Y.

  When the rotating member 44 is in the proximity position, the second contact portion 44bx is disposed downstream of the first contact portion 44ax in the first direction X (see the positioning portion 43a in FIG. 3). According to this configuration, depending on the length of the received paper P in the second direction Y, the rotating member 44 can be any one of the protruding position and the immersion position, and any of the proximity position and the separation position. Or can take an appropriate position reliably. Specifically, when the paper P whose length in the second direction Y is the corresponding length of the rotating member 44 is received, the leading end Px1 of the paper P is in contact with the second contact portion as described above. When the contact occurs, a moment about the second axis Z2 is generated, and the rotation member 44 rotates about the second axis Z2 and moves from the proximity position to the separation position. Positioning in the direction Y can be performed reliably. On the other hand, when the sheet P whose length in the second direction Y is longer than the corresponding length of the rotating member 44 is received, the first contact located upstream of the second contact portion 44bx in the first direction X. When the leading end Px1 of the paper P comes into contact with the portion 44ax first, the rotating member 44 rotates about the first axis Y1 and moves from the protruding position to the immersive position.

  When the rotating member 44 is in the proximity position, the second contact portion 44bx is disposed at a position overlapping the second axis Z2 with respect to the first direction X (see the positioning portion 43a in FIG. 3). According to this configuration, when the rotation member 44 starts to rotate about the second axis Z2 (that is, starts to move from the proximity position to the separation position), the pressing from the paper P that acts on the rotation member 44 is performed. Pressure loss is suppressed, and the pressing force acts efficiently on the rotating member 44. Thereby, the movement of the rotating member 44 from the proximity position to the separation position is performed smoothly, and the sheet P can be reliably positioned in the second direction Y.

  The receiving tray 4 includes a restricting portion 49 configured to restrict the rotation of the rotating member 44 about the first axis Y1 when the rotating member 44 rotates about the second axis Z2. (See FIG. 8). According to this configuration, the paper P can be reliably positioned in the second direction Y.

  The restricting portion 49 includes a first restricting portion (convex portion 44p) provided on the rotating member and a second restricting portion (wall 41x) provided on the receiving member 41, and the rotating member 44 is at the protruding position. In some cases, the second restricting portion (wall 41x) is located outside the movement range of the first restricting portion (convex portion 44p) when the rotating member 44 moves from the protruding position to the immersive position. When rotating from the proximity position about the second axis Z2, the second restricting portion (wall 41x) is located within the moving range. According to the said structure, control and cancellation | release of rotation can be performed appropriately.

  The first restricting portion includes a convex portion 44p that protrudes upstream in the first direction X when the turning member 44 in the turning member 44 is in the protruding position, and the second restricting portion is a support surface of the receiving member 41. It includes a wall 41x that defines holes 41za and 41zc formed in 41a. According to the said structure, the structure of the control part 49 can be simplified.

  The receiving tray 4 includes positioning portions 43a to 43c arranged at different positions with respect to the second direction Y so as to correspond to the other ends Py2 of the sheets Pa to Pc having different lengths in the second direction Y. . According to this configuration, since the plurality of rotating members 44 are arranged at different positions with respect to the second direction Y, they are held at the protruding positions according to the length of the received paper P in the second direction Y. The position of the rotating member 44 is different with respect to the second direction Y. Thereby, the various paper P from which the length of the 2nd direction Y differs can be positioned appropriately.

  The positioning portions 43 a to 43 c are arranged at different positions with respect to the first direction X. When the paper P moving in the first direction X simultaneously contacts the plurality of rotating members 44, the paper P is prevented from moving by receiving the resistance force from the plurality of rotating members 44 at one time, so that an appropriate position is obtained. In some cases it may not be acceptable. The configuration described above is in consideration of this problem, and the paper P moving in the first direction X does not contact with the plurality of rotating members 44 at the same time, and the resistance force from the plurality of rotating members 44 is temporally applied. The above problem can be reduced by receiving it in a distributed manner.

  The spring 46 has a smaller urging force as the positioning portions 43 a to 43 c are arranged on the downstream side in the first direction X. As the sheet P moves in the first direction X when it is received, the distance between the tip Px1 and the roller pair 26 in the vicinity of the discharge port 1b becomes larger, and the first direction X than the roller pair 26 in the sheet P increases. Since the length of the free end on the downstream side is increased, the waist of the tip Px1 portion tends to be weakened. The configuration described above is in consideration of this tendency. By setting the urging force as described above, the waist of the leading end Px1 portion of the paper P is weak on the downstream side in the first direction X, and the pressing from the paper P is difficult. Even when the pressure is small, the rotating member 44 can reliably rotate about the first axis Y1 and move from the protruding position to the immersive position.

  Each of the rotation members 44 is disposed at a position corresponding to the center of the first direction X of the paper P in which the length in the second direction Y is the corresponding length of the rotation member 44. According to this configuration, the paper P can be reliably positioned in the second direction Y.

  Next, a receiving tray according to a second embodiment of the present invention will be described with reference to FIG.

  The receiving tray according to the second embodiment has the same configuration as the receiving tray 4 according to the first embodiment except for the configuration of the positioning portion. The receiving tray according to the second embodiment has positioning portions 243a to 243c shown in FIG. 11 instead of the positioning portions 43a to 43c shown in FIG.

  Each positioning portion 243a to 243c includes a rotating member 244, a second member 248, and two springs (a spring corresponding to a first urging member that urges the rotating member 244 to move from the retracted position toward the protruding position. , And a spring corresponding to a second urging member that urges the rotating member 244 from the separation position toward the proximity position (not shown in FIG. 11).

  The second member 248 is configured to rotate around the second axis Z2, and includes a shaft portion 248a extending in the third direction Z, a shaft portion 248b extending in the second direction Y, and a shaft. And a base portion 248p that supports the portions 248a and 248b.

  The rotation member 244 has substantially the same shape as the rotation member 44 of the first embodiment, and is similar to the columnar portion 44a, the columnar portion 244a having the first contact portion 244ax, and the extension portion 44b. The cylindrical portion 244a is provided with a cylindrical portion 244d shown in FIG. 11 (c) instead of the shaft portion 44d shown in FIG. 10 (c). ing. The cylindrical portion 244d has a hole 244d1 extending in the second direction Y and penetrating in the second direction Y. The shaft portion 248b is inserted into the hole 244d1. Thus, the rotation member 244 is connected to the second member 248 so as to be rotatable about the first axis Y1.

  Also in the present embodiment, the base 248p and the wall provided on the receiving member 41 constitute a restricting portion similar to the restricting portion 49, and the restricting portion causes the rotating members of the positioning portions 243a to 243c to rotate. When the 244 rotates around the second axis Z2, the rotation of the rotating member 244 around the first axis Y1 can be restricted.

  As described above, according to this embodiment, in addition to the same effect by the same configuration as that of the first embodiment, the rotating member 244 is changed to the second member 248 that rotates about the second axis Z2. On the other hand, since the rotation member 244 is attached so as to be rotatable about the first axis Y1, the configuration in which the rotation member 244 rotates about the two axes of the first axis Y1 and the second axis Z2 is compared. The effect that it can implement | achieve easily is acquired.
