  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, the member for positioning the tip of the tag 18 is only one fixed stopper 21. Therefore, the tip of the recording medium cannot be positioned at a position for each length in the first direction of the recording medium.

  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 first direction in the recording medium receiving tray, and to adjust the leading end of the recording medium to It is an object of the present invention to provide a recording medium receiving tray that can be positioned at a position for each length in one direction.

A recording medium receiving tray according to a first aspect of the present invention is a recording medium receiving tray for receiving a recording medium discharged in a first direction from a discharge port of a recording apparatus, and the recording medium discharged from the discharge port. A receiving member configured to receive a receiving member having a support surface for supporting the recording medium, and a plurality of recording media attached to the receiving member and having different lengths in the first direction The lengths of the second direction are different from each other with respect to the first direction so as to correspond to the tips of the first direction , and the lengths of the second direction are orthogonal to the first direction and parallel to the support surface. so as to correspond to each of the second direction of one end of the plurality of recording media, which is disposed at different positions with respect to said second direction, provided with a plurality of positioning portions, wherein the plurality of positioning portions, it Is, it has a first contact portion that contacts the leading end of the recording medium, before Symbol by rotating about a first axis extending in a second direction, said support and projecting position projecting from the support surface A first turning member configured to be able to take an immersion position immersed in the receiving member so as not to protrude from a surface, and the first rotating member attached so as to go from the immersion position toward the protruding position. A first urging member that is urged, and a second rotating member that is disposed at a position corresponding to the one end, the recording medium being disposed upstream of the first contact portion in the first direction. And a second contact portion that contacts the tip of the first axis, and the second axis extends around the second axis extending in the second direction different from the first axis. The second rotation is configured to be able to take the protruding position and the immersion position. Characterized in that it comprises a timber, the.

According to the first aspect of the present invention, in each of the plurality of positioning portions, the first rotating member can be projected and retracted with respect to the receiving member, and the length of the received recording medium in the first direction is the first. In the case of the corresponding length of one rotating member, the length of the received recording medium in the first direction is held at the protruding position against the pressing force from the recording medium moving in the first direction. Is longer than the corresponding length of the first rotating member, it is rotated about the first axis by the pressing force from the recording medium moving in the first direction, so that the protruding position is changed to the immersive position. Moving. This eliminates the need for the user to adjust the position of the positioning portion when receiving recording media having different lengths in the first direction in the recording medium receiving tray. In addition, since the plurality of first rotating members are arranged at different positions with respect to the first direction, the first rotation is held at the protruding position according to the length of the received recording medium in the first direction. The position of the moving member is different with respect to the first direction. Thereby, the front-end | tip of a recording medium can be positioned in the position for every length of the 1st direction of a recording medium. Furthermore, the alignment of the recording medium can be improved by positioning the recording medium in the second direction by the second rotating member.

  In each of the plurality of positioning portions, the second rotating member takes the protruding position when the first rotating member assumes the protruding position, and the first rotating member is the immersion position. When the second rotating member is integrally formed with the first rotating member so that the second rotating member takes the immersive position, an integrated object is formed, and when moving from the protruding position to the immersive position. You may comprise so that it may rotate centering | focusing on the said 1st axis line. According to the said structure, a number of parts can be reduced and a reduction in cost can be implement | achieved by extension.

  In each of the plurality of positioning portions, the first axis is disposed at a position closer to the second contact portion than the first contact portion with respect to the first direction when the integrated object is in the protruding position. Good. According to this configuration, the second contact portion closer to the first axis with respect to the first direction has a pressing force from the recording medium on the contact portion than the first contact portion far from the first axis with respect to the first direction. When acting, a relatively large moment around the first axis is likely to occur. On the other hand, when a pressing force from the recording medium acts on the first contact portion, the moment about the first axis is relatively small. That is, the integrated object is difficult to rotate around the first axis when the recording medium does not contact the second contact portion but contacts the first contact portion (it is difficult to reach the immersion position), and the recording medium does not reach the second contact portion. It is easy to turn around the first axis when it comes into contact (easy to reach the immersive position). Thereby, according to the length of the recording medium received in the 1st direction and the 2nd direction, the integrated thing of each positioning part can take any suitable position of a protrusion position and an immersion position reliably. . Furthermore, according to the said structure, each positioning part contains the integrated object comprised from the 1st rotation member and the 2nd rotation member, and a 1st axis is 2nd rather than a 1st contact part regarding a 1st direction. By being arranged at a position close to the contact portion, setting of the urging force of the first urging member becomes easy. Specifically, in a configuration in which each positioning portion includes the first rotation member and does not include the second rotation member, the first rotation member receives a recording medium having a size corresponding to the first rotation member. Even when a recording medium having a size larger than the size corresponding to the first rotating member is received, there is a high possibility that the leading end of the recording medium contacts the first contact portion. . For this reason, when the recording medium of the corresponding size is received, the first rotating member is held at the protruding position against the pressing force from the recording medium when the biasing force of the first biasing member is received. When a larger recording medium is received, it is necessary to set the first rotating member to move from the protruding position to the immersive position by the pressing force from the recording medium. On the other hand, when the recording medium having a size larger than the size corresponding to the second rotating member is received, the tip of the recording medium comes into contact with the second contact portion. When a recording medium having a size corresponding to the two rotating members is received, there is a high possibility that the tip of the recording medium does not contact the second contact portion. In addition, when the first axis is disposed at a position closer to the second contact portion than the first contact portion in the first direction, as described above, even if the pressing force from the recording medium acts on the first contact portion. The moment about the first axis is relatively small. Therefore, each positioning part includes an integrated body composed of a first rotating member and a second rotating member, and the first axis is closer to the second contact part than the first contact part in the first direction. When arranged, the urging force of the first urging member can be set so that the integrated object moves from the protruding position to the immersive position when the pressing force from the recording medium acts on the second contact portion. Thus, each positioning part includes the integrated object comprised from the 1st rotation member and the 2nd rotation member, and the 1st axis is nearer to the 2nd contact part than the 1st contact part about the 1st direction When arranged in the position, setting of the urging force of the first urging member is facilitated as compared with the case where each positioning portion includes the first rotating member and does not include the second rotating member.

  In each of the plurality of positioning portions, the integrated object may have an L shape when viewed from the third direction orthogonal to the first direction and the second direction when the integrated object is in the protruding position. . According to the said structure, the structure of an integrated object can be simplified.

  In each of the plurality of positioning portions, the second rotation member is a member different from the first rotation member, and the second axis is centered on the second axis when moving from the protruding position to the retracted position. Each of the plurality of positioning portions further includes a second urging member that urges the second rotating member toward the protruding position from the retracted position. Good. According to the said structure, the structure of each member can be simplified by making a 1st rotation member and a 2nd rotation member into a different body.

The recording medium receiving tray according to the first aspect of the present invention is provided for each of the plurality of positioning portions, and when the second rotating member is in the protruding position, You may further provide the some control part comprised so that rotation around the said 1st axis line may be controlled. According to the said structure, while making the 1st rotation member and 2nd rotation member which were comprised by the separate body interlock | cooperate, each rotation member is hold | maintained in any one of a protrusion position and an immersion position. Can do. Specifically, when the second rotating member is at the protruding position, the corresponding first rotating member is also held at the protruding position by the restriction by the restricting portion. That is, when the second rotating member is in the protruding position, the restricting portion restricts that only the first rotating member moves from the protruding position to the immersive position. On the other hand, when the second rotating member rotates about the second axis and moves from the protruding position to the immersive position, the restriction by the restricting portion is released, and the first rotating member responds to the pressing force from the recording medium. It is possible to rotate about the first axis (that is, it is possible to move from the protruding position to the immersive position). Furthermore, according to the said structure, the setting of the urging | biasing force of a 1st urging | biasing member and a 2nd urging | biasing member is possible because each positioning part contains a 1st rotation member and a 2nd rotation member, and has a control part. It becomes easy. Specifically, in a configuration in which each positioning portion includes the first rotation member and does not include the second rotation member, the first rotation member receives a recording medium having a size corresponding to the first rotation member. Even when a recording medium having a size larger than the size corresponding to the first rotating member is received, there is a high possibility that the leading end of the recording medium contacts the first contact portion. . For this reason, when the recording medium of the corresponding size is received, the first rotating member is held at the protruding position against the pressing force from the recording medium when the biasing force of the first biasing member is received. When a larger recording medium is received, it is necessary to set the first rotating member to move from the protruding position to the immersive position by the pressing force from the recording medium. On the other hand, when the recording medium having a size larger than the size corresponding to the second rotating member is received, the tip of the recording medium comes into contact with the second contact portion. When a recording medium having a size corresponding to the two rotating members is received, there is a high possibility that the tip of the recording medium does not contact the second contact portion. Therefore, the urging force of the second urging member can be set so that the second rotating member moves from the protruding position to the immersive position when the pressing force from the recording medium acts on the second contact portion. In addition, the urging force of the first urging member is such that when the pressing force from the recording medium acts on the first contact portion in a state where the restriction by the restricting portion is released, the first rotating member is moved from the protruding position to the immersive position. Can be set to move to. As described above, when each positioning portion includes the first rotating member and the second rotating member and includes the restricting portion, each positioning portion includes the first rotating member and does not include the second rotating member. Thus, setting of the urging force of the first urging member and the second urging member becomes easy.

  Each of the plurality of restricting portions includes a first restricting portion provided on the first rotating member and a second restricting portion provided on the second rotating member, and the second rotating member includes When in the protruding position, the second restricting portion is located within a moving range of the first restricting portion when the first rotating member moves from the protruding position to the retracted position. When the moving member rotates around the second axis from the protruding position, the second restricting portion may be located outside the moving range. According to the said structure, control and cancellation | release of rotation can be performed appropriately.

  The first restricting portion is a facing surface formed on the first rotating member, and the first rotating member and the second rotating member are in the protruding position when the first rotating member and the second rotating member are in the protruding position. 2 including a facing surface facing the restricting portion, wherein the second restricting portion is a convex portion formed on the second rotating member, and the first rotating member is located at the protruding position when the first rotating member is in the protruding position. You may include the convex part which protruded in the downstream of the direction. According to the said structure, the structure of a control part can be simplified.

  The plurality of second 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 second rotating member can reliably move around the second axis and move from the protruding position to the immersive position.

A recording medium receiving tray according to a second aspect of the present invention is a recording medium receiving tray for receiving a recording medium discharged in a first direction from a discharge port of a recording apparatus. A receiving member configured to receive a receiving member having a support surface for supporting the recording medium, and a plurality of recording media attached to the receiving member and having different lengths in the first direction A plurality of positioning portions arranged at different positions with respect to the first direction so as to correspond to the respective leading ends in the first direction, and the plurality of positioning portions are respectively the leading ends of the recording medium.

  The integrated object 46 rotates around the first axis Y1 extending in the second direction Y, thereby protruding from the support surface 41a (the integrated object of the positioning portions 43b and 43c in FIG. 5A). 46) and an immersion position (see FIG. 5 (b), which is an integral part of the positioning portion 43a) that is immersed in the receiving member 41 so as not to protrude from the support surface 41a. 7A to 7D show a state in which the integrated object 46 of the positioning portion 43a moves from the protruding position to the immersive position.

  As shown in FIG. 3, the monolith 46 is L-shaped when viewed from the third direction Z when in the protruding position. The second contact portion 45x is disposed on the upstream side in the first direction X with respect to the first contact portion 44x. At this time, the first axis Y1 is arranged in a position closer to the second contact portion 45x than the first contact portion 44x in the first direction X. The positional relationship is established in all of the positioning portions 43a to 43c.

  With respect to the positioning portion 43a, when the integrated object 46 is in the protruding 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 contacts the first contact portion 44x. However, the integrated object 46 is arranged at a position where it does not contact the second contact portion 45x. Further, with respect to the positioning portion 43a, when the integrated object 46 is in the protruding position, the sheets Pb and Pc having longer lengths in the first direction X and the second direction Y than the sheet Pa corresponding to the positioning portion 43a are discharged from the discharge port 1b. The integrated object 46 is arranged at a position where the leading end Px1 of the paper Pb, Pc comes into contact with the second contact portion 45x when discharged. Similarly, in the case of the paper P of the corresponding size, the positioning portions 43b and 43c correspond to the leading end Px1 of the paper P that contacts the first contact portion 44x but not the second contact portion 45x. In the case of the paper P whose length in the first direction X and the second direction Y is longer than the size to be processed, the integrated object 46 is disposed at a position where the leading end Px1 of the paper P contacts the second contact portion 45x. ing.

  The spring 47 includes a coiled portion wound around the shaft portion 45 a, one end attached to the second rotating member 45, and the other end attached to the receiving member 41. The spring 47 urges the integrated object 46 so as to go from the immersion position to the protruding position. That is, the spring 47 corresponds to the first biasing member of the present invention. When the leading end Px1 of the paper P having a longer length in the first direction X and the second direction Y than the corresponding paper Pa to Pc is brought into contact with the second contact portion 45x, the spring 47 is integrated with the positioning portions 43a to 43c. The biasing force is set such that the object 46 is moved from the protruding position to the immersive position by the pressing force received from the paper P.

  The spring 47 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. That is, the biasing force of the spring 47 of the positioning portion 43b is smaller than the biasing force of the spring 47 of the positioning portion 43a. The biasing force of the spring 47 of the positioning portion 43c is smaller than the biasing force of the spring 47 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 can be taken by rotating about the axis extending in the second direction Y, as in the case of each integrated body 46. Configured to get.

  In FIG. 3, all of the integrated members 46 of the protruding members 42 a to 42 c and the positioning portions 43 a to 43 c are in the protruding position.

  In FIG. 4, all of the integrated members 46 of the protruding members 42 a to 42 c and the positioning portions 43 a to 43 c are in the protruding position. At this time, one end Py1 of the paper Pa contacts or faces one of the three protruding members 42a and the facing portion 45y of the second rotating member 45 of the positioning portion 43a, and the other end Py2 of the paper Pa. Is in contact with or opposed to two of the three protruding members 42a.

  In FIG. 5, the three protruding members 42 a and the integrated member 46 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 one piece 46 is in the protruding position. At this time, one end Py1 of the paper Pb contacts or faces one of the three protruding members 42b and the facing portion 45y of the second rotating member 45 of the positioning portion 43b, and the other end Py2 of the paper Pb. Is in contact with or opposed to two of the three projecting members 42b.

  In FIG. 6, the protruding members 42 a and 42 b and the integrated member 46 of the positioning portions 43 a and 43 b are in the immersive position (not shown because they are below the paper Pc), and the three protruding members 42 c and the positioning portions 43 c The one piece 46 is in the protruding position. At this time, one end Py1 of the paper Pc contacts or faces one of the three projecting members 42c and the facing portion 45y of the second rotating member 45 of the positioning portion 43c, and the other end Py2 of the paper Pc. Is in contact with or opposed to two of the three projecting members 42c.

  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 comes into contact with two of the three protruding members 42a upstream in the first direction X, and the two are moved from the protruding position to the immersive position. In addition, one of the three projecting members 42a on the downstream side in the first direction X and the second contact portion 45x of the second rotating member 45 of the positioning portion 43a are substantially simultaneously contacted (FIG. 7A). ), (B)). When the paper Pb further moves in the first direction X, the integrated object 46 of the positioning portion 43a is rotated about the first axis Y1 by the pressing force from the paper Pb moving in the first direction X, and from the protruding position. Move to the immersive position (see FIGS. 7B and 7C). At this time, one of the three projecting members 42a on the downstream 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 comes into contact with the first contact portion 44x of the first rotating member 44 of the positioning portion 43b (see FIGS. 7C and 7D). At this time, the integrated object 46 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 (see FIGS. 7C and 7D). Accordingly, the movement of the paper Pb in the first direction X is stopped, and the paper Pb is appropriately positioned in the first direction X by the first rotating member 44 of the positioning unit 43b, and at the same time, the second rotating member 45 of the positioning unit 43b. And the three protruding members 42b are appropriately positioned in the second direction Y. At this time, the paper Pb is disposed between the second rotating member 45 and the three protruding members 42b of the positioning portion 43b. One end Py1 of the paper Pa contacts or opposes one of the three protruding members 42b and the facing portion 45y of the second rotating member 45 of the positioning portion 43b, and the other end Py2 of the paper Pa is 3 It contacts or faces two of the two protruding members 42b. That is, there may be a gap between the one end Py1 and the second rotating member 45 and the protruding member 42b, or there may be no gap. Similarly, there may be a gap or no gap between the other end Py2 and the protruding member 42b.

  As described above, according to the present embodiment, in each of the positioning portions 43a to 43c, the first rotation member 44 can be moved in and out of the receiving member 41, and the first direction of the received paper P is received. When the length of X is the corresponding length of the first rotating member 44, it is held at the protruding position against the pressing force from the paper P moving in the first direction X, but is received. When the length of the sheet P in the first direction X is longer than the corresponding length of the first rotating member 44, the first axis Y1 is centered by the pressing force from the sheet P moving in the first direction X. To move to the immersive position from the protruding position (see 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 the receiving tray 4 receives the paper P having a different length in the first direction X. In addition, since the first rotating members 44 of the positioning portions 43a to 43c are arranged at different positions with respect to the first direction X, the protruding position depends on the length of the received paper P in the first direction X. The position of the first rotation member 44 held by the head is different with respect to the first direction. Thereby, the front end Px1 of the paper P can be positioned at a position for each length of the paper P in the first direction X. As a result, the position of the trailing edge Px2 of the paper P can be aligned regardless of the length of the paper P in the first direction X.

  Each positioning portion 43 a to 43 c includes a second rotating member 45 in addition to the first rotating member 44. According to this configuration, the alignment of the paper P can be improved by positioning the paper P in the second direction Y by the second rotating member 45.

  The second rotating member 45 is formed integrally with the first rotating member 44 to constitute an integrated object 46. According to the said structure, a number of parts can be reduced and a reduction in cost can be implement | achieved by extension.

  The first axis Y1 is disposed at a position closer to the second contact portion 45x than the first contact portion 44x in the first direction X when the integrated object 46 is in the protruding position (see FIG. 3). According to this configuration, the second contact portion 45x that is closer to the first axis Y1 with respect to the first direction X is closer to the contact portion than the first contact portion 44x that is farther from the first axis Y1 with respect to the first direction X. When a pressing force from P is applied, a relatively large moment is easily generated around the first axis Y1. On the other hand, when a pressing force from the paper P acts on the first contact portion 44x, the moment about the first axis Y1 is relatively small. That is, the integrated object 46 is difficult to rotate around the first axis Y1 when the paper P does not contact the second contact portion 45x but contacts the first contact portion 44x (it is difficult to reach the immersive position). When it comes into contact with the second contact portion 45x, it is easy to rotate around the first axis Y1 (easy to reach the immersion position). As a result, depending on the lengths of the received paper P in the first direction X and the second direction Y, the integrated object 46 of the positioning portions 43a to 43c is set to any suitable position between the protruding position and the immersion position. Can be taken reliably.

  Furthermore, each positioning part 43a-43c contains the integrated object 46 comprised from the 1st rotation member 44 and the 2nd rotation member 45, and the 1st axis line Y1 is the 1st direction X from the 1st contact part 44x. Also, since the second contact portion 45x is disposed at a position close to the second contact portion 45x, the setting of the biasing force of the first biasing member (in this embodiment, the spring 47) is facilitated. Specifically, in a configuration in which each positioning portion 43 a to 43 c includes the first rotation member 44 and does not include the second rotation member 45, the first rotation member 44 corresponds to the first rotation member 44. Even when the paper P having the size is received or when the paper P having a size larger than the size corresponding to the first rotation member 44 is received, the leading end Px1 of the paper P is the first. There is a high possibility of contact with the contact portion 44x. Therefore, when the paper P having a corresponding size is received as the urging force of the first urging member, the first rotating member 44 is held at the protruding position against the pressing force from the paper P, and the corresponding force is applied. When a paper P larger than the size is received, it is necessary to set the first rotating member 44 to move from the protruding position to the immersive position by the pressing force from the paper P (for example, a small size paper) In the positioning part 43a corresponding to Pa, it is necessary to set the urging force S of the first urging member within the range shown in FIG. 9A). On the other hand, when the paper P having a size larger than the size corresponding to the second rotating member 45 is received, the leading end Px1 of the paper P contacts the second contact portion 45x. However, when the paper P having a size corresponding to the second rotating member 45 is received, there is a high possibility that the leading end Px1 of the paper P does not contact the second contact portion 45x. In addition, when the first axis line Y1 is disposed at a position closer to the second contact portion 45x than the first contact portion 44x with respect to the first direction X, the pressing force from the paper P is applied to the first contact portion 44x as described above. Even when acting on the moment, the moment about the first axis Y1 becomes relatively small.

Here, the moment about the first axis Y1 will be described with reference to FIG. In FIG. 8C, the first direction X is a direction from right to left from the left to the right. Here, it is assumed that a force having the same magnitude in the first direction X acts on the first contact portion 44x and the second contact portion 45x. In this case, among the forces of the first direction X that acts on the first contact portion 44x, component of the force to rotate the single piece 46 about the first axis Y1 is applied to the second contact portion 4 5 x Among the forces in the first direction X, the force component is larger than the force component that tries to rotate the integrated object 46 about the first axis Y1. Therefore, when the leading end Px1 of the paper P does not contact the second contact portion 45x but contacts the first contact portion 44x, the integral object 46 is difficult to rotate around the first axis Y1, and the leading end Px1 of the paper P is When the two contact portions 45x are contacted with each other, the urging force of the first urging member can be easily set by configuring the second urging member 45x so that the second urging member 45x is easily rotated about the first axis Y1. That is, each positioning portion 43a to 43c includes an integrated object 46 composed of the first rotating member 44 and the second rotating member 45, and the first axis Y1 is from the first contact portion 44x in the first direction X. If the first contact member 45x is disposed at a position close to the second contact portion 45x, the urging force of the first urging member is applied to the second contact portion 45x when the pressing force from the paper P acts on the second contact portion 45x. (For example, in the positioning portion 43a corresponding to the small-size paper Pa, the urging force S of the first urging member can be set within the range shown in FIG. 9B.) In the example of Fig. 9, there is a range of pressing force for each size because the pressing force varies depending on the type, thickness, waist, etc. of the paper P). Thus, each positioning part 43a-43c contains the integrated object 46 comprised from the 1st rotation member 44 and the 2nd rotation member 45, and the 1st axis line Y1 is the 1st contact part regarding the 1st direction X. Compared to the case where each positioning portion 43a to 43c includes the first rotating member 44 and does not include the second rotating member 45, the first attached portion is arranged in a position closer to the second contact portion 45x than 44x. Setting of the urging force of the urging member becomes easy.

  When the integral object 46 is in the protruding position, it is L-shaped when viewed from the third direction Z (see FIG. 3). According to the said structure, the structure of the integral object 46 can be simplified.

  The spring 47 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 integrated object 46 can reliably rotate about the first axis Y1 and move from the protruding position to the immersive position.

  Next, the receiving tray 204 according to the second embodiment of the present invention will be described with reference to FIGS. 10 and 11.

  The receiving tray 204 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 204 has positioning portions 243a to 243c shown in FIG. 10 instead of the positioning portions 43a to 43c.

  Each of the positioning portions 243a to 243c is not an integrated object 46 in which the first rotating member 44 and the second rotating member 45 are integrally formed, but the first rotating member 244 and the second rotating member made of different members. A rotating member 245 and springs 247 and 248 are included.

  The first rotating member 244 is a rectangular plate member, and one surface of the first rotating member 244 constitutes a first contact portion 244x that contacts the leading end Px1 of the paper P. The first rotating member 244 has a shaft portion 244a extending in the second direction Y in the vicinity of the lower end. The first rotating member 244 rotates around the first axis Y1 extending in the second direction Y, so that the protruding position (see FIG. 11 (a)) and the immersion position (see FIG. 11 (b)). It is comprised so that it can take.

  The second rotating member 245 has the same shape as the protruding members 42a to 42c of the first embodiment, and one surface thereof constitutes a second contact portion 245x that contacts the leading end Px1 of the paper P. . The second rotating member 245 has a shaft portion 245a extending in the second direction Y in the vicinity of the lower end. The second rotating member 245 rotates around a second axis Y2 extending in the second direction Y, which is different from the first axis Y1, so that a protruding position (see FIG. 10) and an immersion position (see FIG. 11 (b)). 11A and 11B show how the second rotating member 245 moves from the protruding position to the immersive position.

  As shown in FIG. 10, when the rotating members 244 and 245 are in the protruding position, the second contact portion 245x is disposed on the upstream side in the first direction X with respect to the first contact portion 244x.

  With respect to the positioning portion 243a, when the rotating members 244 and 245 are in the projecting positions, 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 first contact portion 244x. The rotating members 244 and 245 are arranged at positions where they contact each other but do not contact the second contact portion 245x. Further, with respect to the positioning portion 243a, when the rotating members 244 and 245 are in the protruding positions, the sheets Pb and Pc having a length in the first direction X and the second direction Y longer than the sheet Pa corresponding to the positioning portion 243a are discharged. The rotating members 244 and 245 are arranged at positions where the leading ends Px1 of the sheets Pb and Pc come into contact with the second contact portion 245x when discharged from the outlet 1b. Similarly, with respect to the positioning portions 243b and 243c, in the case of the paper P of the corresponding size, the front end Px1 of the paper P contacts the first contact portion 244x but does not contact the second contact portion 245x. In the case of the paper P having a longer length in the first direction X and the second direction Y than the size to be rotated, the rotating members 244 and 245 are positioned so that the front end Px1 of the paper P contacts the second contact portion 245x. Is arranged.

  The spring 247 includes a coil-shaped portion wound around the shaft portion 244 a, one end attached to the first rotating member 244, and the other end attached to the receiving member 41. The spring 247 biases the first rotating member 244 so as to go from the retracted position to the protruding position. That is, the spring 247 corresponds to the first biasing member of the present invention. When the leading end Px1 of the paper P whose length in the first direction X is longer than the corresponding paper Pa to Pc is in contact with the first contact portion 244x for each positioning portion 243a to 243c, the spring 247 is in contact with the first rotating member 244. 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 248 includes a coil-shaped portion wound around the shaft portion 245 a, one end attached to the second rotating member 245, and the other end attached to the receiving member 41. The spring 248 biases the second rotating member 245 so as to go from the retracted position to the protruding position. That is, the spring 248 corresponds to the second biasing member of the present invention. 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 second contact portion 245x, the spring 248 moves to the second rotating member 245 for each positioning portion 243a to 243c. 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 247 has a smaller biasing force as the positioning portions 243a to 243c are arranged on the downstream side in the first direction X. Similarly, the biasing force of the spring 248 is smaller as the positioning portions 243a to 243c are arranged on the downstream side in the first direction X.

  In each of the positioning portions 243a to 243c, the first rotation member 244 and the second rotation member 245 can be moved in and out of the receiving member 41, and the first direction X and the second direction of the received paper P are received. When the length of Y is the corresponding length of the positioning portions 243a to 243c, the Y is held at the protruding position against the pressing force from the paper P moving in the first direction X, but is received. When the lengths of the paper P in the first direction X and the second direction Y are longer than the corresponding lengths of the positioning portions 243a to 243c, the first axis line is generated by the pressing force from the paper P moving in the first direction X. By rotating around Y1 and the second axis Y2, the projection position moves to the immersion position (see FIGS. 11A and 11B).

  The receiving tray 204 regulates the rotation of the first rotation member 244 around the first axis Y1 when the second rotation member 245 is in the protruding position with respect to the positioning portions 243a to 243c. It has the control part 249 comprised in this way. The restricting portion 249 includes a facing surface 244p provided on the first rotating member 244 and a convex portion 245p provided on the second rotating member 245. The facing surface 244p corresponds to the first restricting portion of the present invention. The convex portion 245p corresponds to the second restricting portion of the present invention. The facing surface 244p is a surface formed on the first rotating member 244 and is a surface facing the convex portion 245p with respect to the first direction X when the rotating members 244 and 245 are in the protruding positions (FIG. 10). reference). The convex portion 245p protrudes downstream in the first direction X when the second rotating member 245 is in the protruding position. When the second rotating member 245 is in the protruding position, the convex portion 245p is positioned within the moving range of the facing surface 244p when the first rotating member 244 moves from the protruding position to the immersive position. At this time, the rotation of the first rotating member 244 around the first axis Y1 is restricted, and the first rotating member 244 cannot move from the protruding position to the immersive position and is held at the protruding position. Is done. On the other hand, when the second rotating member 245 rotates about the second axis Y2 and moves from the protruding position toward the immersive position (see the solid arrow in FIG. 10), the convex portion 245p is positioned outside the moving range ( (See dotted arrow in FIG. 10). At this time, the restriction on the rotation of the first rotation member 244 around the first axis Y1 is released, and the first rotation member 244 is centered on the first axis Y1 according to the pressing force from the paper P. It is possible to rotate (that is, move from the protruding position to the immersive position) (see FIGS. 11A and 11B).

  In each positioning part 243a to 243c, when the lengths of the received paper P in the first direction X and the second direction Y are the corresponding lengths of the positioning parts 243a to 243c, they move in the first direction X. The leading edge Px1 of the sheet P to be contacted contacts the first contact portion 244x but does not contact the second contact portion 245x. Therefore, the pressing force from the paper P acts only on the first rotating member 244. At this time, the first rotating member 244 is held at the protruding position against the pressing force from the paper P because the movement from the protruding position to the immersive position is restricted by the restricting portion 249. On the other hand, in the positioning portions 243a to 243c, when the lengths of the received paper P in the first direction X and the second direction Y are longer than the corresponding lengths of the positioning portions 243a to 243c, the first direction X First, the leading end Px1 of the paper P that moves to the first position contacts the second contact portion 245x. Then, the second rotating member 245 moves from the protruding position to the immersive position by the pressing force from the paper P. When the paper P further moves in the first direction X, the leading end Px1 of the paper P comes into contact with the first contact portion 244x. At this time, the second rotating member 245 has moved toward the immersion position, and the restriction by the restriction portion 249 has been released. Therefore, the first rotating member 244 moves from the protruding position to the immersive position by the pressing force from the paper P.

  As described above, according to this embodiment, the following effects can be obtained in addition to the same effects by the same configuration as that of the first embodiment.

  By making the 1st rotation member 244 and the 2nd rotation member 245 into a different body, the structure of each member 244,245 can be simplified.

  The receiving tray 204 restricts the rotation of the first rotation member 244 around the first axis Y1 when the second rotation member 245 is in the protruding position with respect to the positioning portions 243a to 243c. It has a restricting portion 249 configured. According to this configuration, the first rotating member 244 and the second rotating member 245 configured separately are interlocked, and each of the rotating members 244 and 245 is any one of the protruding position and the immersion position. Can be held in position.

  Furthermore, according to the said structure, each positioning part 243a-243c contains the 1st rotation member 244 and the 2nd rotation member 245, and has the control part 249, Therefore A 1st biasing member (in this embodiment, The setting of the urging force of the spring 247) and the second urging member (in this embodiment, the spring 248) is facilitated. Specifically, in the configuration in which each positioning portion 243a to 243c includes the first rotation member 244 and does not include the second rotation member 245, the first rotation member 244 corresponds to the first rotation member 244. Even when the paper P having the size is received or when the paper P having a size larger than the size corresponding to the first rotating member 244 is received, the leading end of the paper P is Px1 first. There is a high possibility of contact with the contact portion 244x. Therefore, when the paper P having a corresponding size is received as the biasing force of the first biasing member, the first rotating member 244 is held at the protruding position against the pressing force from the paper P, and the corresponding force is applied. When a paper P larger than the size is received, it is necessary to set the first rotating member 244 to move from the protruding position to the immersive position by the pressing force from the paper P. On the other hand, when the sheet P having a size larger than the size corresponding to the second rotating member 245 is received, the leading end Px1 of the sheet P contacts the second contact portion 245x. However, when the paper P having a size corresponding to the second rotating member 245 is received, there is a high possibility that the front end Px1 of the paper P does not contact the second contact portion 245x. Therefore, the urging force of the second urging member can be set so that the second rotating member 245 moves from the protruding position to the immersive position when the pressing force from the paper P acts on the second contact portion 245x. it can. In addition, the urging force of the first urging member is such that when the pressing force from the paper P acts on the first contact portion 244x in a state where the restriction by the restriction portion 249 is released, the first rotating member 244 is in the protruding position. It can be set to move from to the immersive position. Thus, when each positioning part 243a-243c contains the 1st rotation member 244 and the 2nd rotation member 245, and has the control part 249, each positioning part 243a-243c contains the 1st rotation member 244, and is 1st. Compared with the case where the two rotating members 245 are not included, setting of the urging forces of the first urging member and the second urging member is facilitated.

  Each restricting portion 249 includes a first restricting portion (opposing surface 244p) provided on the first rotating member 244 and a second restricting portion (convex portion 245p) provided on the second rotating member 245, When the second rotating member 245 is in the protruding position, the second restricting portion (convex portion 245p) is the first restricting portion (opposing surface 244p) when the first rotating member 244 is moved from the protruding position to the immersive position. When the second rotating member 245 rotates around the second axis Y2 from the protruding position, the second restricting portion (the convex portion 245p) is positioned outside the moving range. . According to the said structure, control and cancellation | release of rotation can be performed appropriately. Further, the provision of the restricting portion 249 in each of the positioning portions 243a to 243c facilitates setting of the urging force of the springs 247 and 248 (the first urging member and the second urging member).

  The first restricting portion has a facing surface 244p facing the second restricting portion in the first direction X when the first turning member 244 and the second turning member 245 in the first turning member 244 are in the protruding position. The second restricting portion is a convex portion 245p formed on the second rotating member 245, and protrudes downstream in the first direction X when the second rotating member 245 is in the protruding position. 245p is included. According to the said structure, the structure of the control part 249 can be simplified.

  The springs 247 and 248 have smaller urging forces as the positioning portions 243a to 243c 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 members 244 and 245 can reliably rotate about the axes Y1 and Y2 and move from the protruding position to the immersive position.

  Next, a receiving tray 304 according to a third embodiment of the present invention will be described with reference to FIG.

  The receiving tray 304 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 304 has positioning portions 343a to 343c shown in FIG. 12 instead of the positioning portions 43a to 43c.

  Each positioning portion 343a to 343c is obtained by omitting the second rotating member 45 in each positioning portion 43a to 43c, and includes a first rotating member 44 and a spring 47. In the present embodiment, the second rotating member 45 is omitted. However, as in the first embodiment, the first rotating member 44 is received in the first direction X of the paper P in which the first rotating member 44 is received in the positioning portions 343a to 343c. Since it is possible to appear and appear according to the length, the same effect as the first embodiment can be obtained.
