Japanese Patent No. 3668106

  Providing a stopper on the receiving tray as in Patent Document 1 is effective in ensuring alignment of the medium conveyed at high speed in the receiving tray. However, when a plurality of receiving trays are provided for sorting the media and the plurality of receiving trays are arranged in the vertical direction, the receiving trays other than the uppermost tray (lower tray) receive other receiving trays upward. Since there is a tray, it is difficult to take out the medium above, and because there is a stopper, it is difficult to take out the medium in the transport direction.

  Therefore, the inventor of the present application has a base with the lower tray attached to the tray main body so as to be movable in the transport direction so that the user can take out the medium received in the lower tray in the transport direction. As a result of examining a configuration including a stopper that is rotatably mounted, the following problems were found. Specifically, when the user takes out the medium in the transport direction, when the stopper rotates with respect to the base, the base receives the force accompanying the rotation of the stopper and moves with respect to the tray body.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a transport device and a receiving tray in which a user can take out a medium received in a lower layer tray in the transport direction, and can suppress a problem that a base moves with respect to the tray body. There is.

  The transport device according to the present invention has a receiving surface for receiving a medium, and is selectively selected from a plurality of receiving trays arranged in a vertical direction and the receiving surfaces of the plurality of receiving trays. 1 or a plurality of lower layer trays that are receiving trays other than the uppermost tray disposed at least above the plurality of receiving trays. A tray main body constituting the receiving surface, a base attached to the tray main body so as to be movable in a medium transport direction by the transport mechanism when the medium is received in the receiver tray, and the base A stopper attached to the base so as to be rotatable, and by rotating with respect to the base, an end surface on the upstream side in the transport direction is in the transport direction of the medium received by the receiving surface. A stopper that can take a stopper position that opposes a portion, a rotation position where the angle between the end surface and the receiving surface is larger than that at the stopper position, and a positioning mechanism for positioning the base on the tray body And a movement restricting mechanism for restricting movement of the base in the transport direction relative to the tray body when the stopper moves from the stopper position to the pivot position.

  The receiving tray according to the present invention has a receiving surface for receiving a medium, and is selective to any one of a plurality of receiving trays arranged in a vertical direction and the receiving surfaces of the plurality of receiving trays. 1 or a plurality of receiving trays other than the uppermost tray disposed at least at the uppermost position among the plurality of receiving trays in a transport device including a transport mechanism for transporting a medium so that the medium is received by A receiving tray used as one of the lower layer trays, a tray main body constituting the receiving surface, a base attached to the tray main body so as to be movable in the transport direction, and a rotation with respect to the base. A stopper that is movably attached and rotates with respect to the base so that the upstream end surface in the transport direction is the end in the transport direction of the medium received by the receiving surface. A stopper position that can take a position where the angle between the end surface and the receiving surface is larger than that in the stopper position, and a positioning mechanism for positioning the base on the tray body And a movement restricting mechanism for restricting movement of the base in the transport direction relative to the tray body when the stopper moves from the stopper position to the pivot position.

  According to the present invention, at least the lower layer tray adopts a configuration including a base attached to the tray main body so as to be movable in the transport direction and a stopper attached to the base so as to be rotatable. The user can take out the medium received in the lower tray in the transport direction. Furthermore, the problem that the base moves relative to the tray body can be suppressed by providing the movement restricting mechanism.

  The movement restricting mechanism may restrict movement of the base in the transport direction relative to the tray body in cooperation with the positioning mechanism when the stopper moves from the stopper position to the pivot position. In this case, since the movement restriction mechanism cooperates with the positioning mechanism to restrict the movement of the base, the structure of the movement restriction mechanism can be simplified.

  The movement restricting mechanism may be configured such that a restricting force for restricting the movement changes in a binary manner when the stopper takes the stopper position and when the stopper takes the rotational position. In this case, the movement control of the base accompanying the rotation of the stopper can be quickly performed.

  At least the one or more lower trays of the plurality of receiving trays may further include a biasing member that biases the stopper in a direction from the rotation position toward the stopper position. In this case, after the stopper is moved from the stopper position to the rotation position and the medium is taken out, the stopper returns from the rotation position to the stopper position by the urging force of the urging member. This eliminates the need for the user to return the stopper from the rotation position to the stopper position.

  The positioning mechanism includes a convex portion provided on one of the base and the tray main body and formed on an elastic portion that is elastically deformable, and a concave portion provided on the other of the base and the tray main body. The portion is configured to be able to take a fitting position that fits into the recess and a retracted position that retracts from the recess according to elastic deformation of the elastic portion, and the movement restricting mechanism includes the stopper May be configured to abut against the elastic portion and restrict elastic deformation of the elastic portion when moving from the stopper position to the rotating position. In this case, the configuration can be simplified as compared with the case where an electrical mechanism or the like is used.

  In the one or more lower layer trays, a receiving tray in which at least a part of a projection region obtained by projecting the receiving surface of the lower layer tray onto a virtual plane perpendicular to the vertical direction from the vertical direction is disposed above the lower layer tray. Any one of the above may overlap with a projected area projected from the vertical direction on the virtual plane.

  A regulating member that regulates removal of the medium from the receiving surface in a direction perpendicular to both the vertical direction and the transport direction may be provided for at least the one or more lower trays of the plurality of receiving trays. . In this case, the medium received in the lower layer tray is difficult to take out in the orthogonal direction because of the restriction member, and is taken out in the transport direction. At this time, the stopper may be an obstacle, but it is easy to take out the medium in the transport direction by adopting a configuration in which the stopper rotates with respect to the base.

  According to the present invention, at least the lower layer tray employs a configuration including a base that is movably attached to the tray body in the transport direction, and a stopper that is rotatably attached to the base. The medium received in the lower tray can be taken out in the transport direction. Furthermore, the problem that the base moves relative to the tray body can be suppressed by providing the movement restricting mechanism.

To the position where the paper P is guided to the path R6.

  As shown in FIG. 3, the control unit 1c includes a CPU (Central Processing Unit) 1c1, a ROM (Read Only Memory) 1c2, a RAM (Random Access Memory) 1c3, an ASIC (Application Specific Integrated Circuit) 1c4, It has I / F (Interface) 1c5 and I / O (Input / Output Port) 1c6. The ROM 1c2 stores fixed data such as a program executed by the CPU 1c1. The RAM 1c3 temporarily stores data necessary for the CPU 1c1 to execute the program. The ASIC 1c4 performs rewriting and rearrangement of image data (for example, signal processing and image processing). The I / F 1c5 transmits / receives data to / from an external device (for example, a PC connected to the printer 1). The I / O 1c6 transmits and receives signals to and from various sensors. The CPU 1c1 is electrically connected to each unit other than the CPU 1c1 included in the control unit 1c, and controls each unit of the printer 1 based on data received from each unit.

  The controller 1c is electrically connected to a contact C1 provided on the upper surface of the housing 1x. When the tray unit 50 is mounted on the housing 1x, the contact C1 and the contact C2 provided on the lower surface of the support member 51 come into contact with each other and are electrically connected. The contact C2 is electrically connected to the transport motor 30bM and the switching motors F2M to F5M of the tray unit 50.

Thereby, transmission / reception of the signal between the control part 1c and the conveyance motor and switching motor of another tray unit is attained.

  When the paper P transported by the transport mechanism 30 passes between the ejection surface 10x and the support surface 11x under the control of the control unit 1c, the actuator of the head 10 is driven to form a plurality of sheets formed on the ejection surface 10x. Ink is selectively ejected from these ejection openings. As the ejected ink lands on the paper P, an image is formed on the paper P (that is, recording on the paper P is performed). The recorded paper P is further transported by the transport mechanism 30 and is selectively received by any of the receiving trays 12, 52a to 52d.

  When the paper P is received in the receiving trays 12, 52 a to 52 d, the paper P is transported along the transport direction D, and the leading end abuts against the stoppers 15, 55 and falls, and the receiving trays 12, 52 a to 52 d It is received by the receiving surfaces 13a and 53a.

  Next, the configuration of the base 54 and the stopper 55 will be described in detail with reference to FIGS.

  The stopper 55 includes a cylindrical rotation shaft 55x having an axis 55x1 along the main scanning direction, and a flat stopper body 55y fixed on the rotation shaft 55x. The stopper main body 55y extends from the rotation shaft 55x in a direction orthogonal to the main scanning direction.

  The base 54 includes a bottom plate 54x and a cover 54y disposed on the bottom plate 54x. The bottom plate 54x is provided with a plurality of bearings 54x1 for supporting the rotation shaft 55x. Each bearing 54x1 has a concave surface corresponding to supporting the peripheral surface of the rotation shaft 55x. A pair of through holes 54y1 into which the rotation shaft 55x is inserted are formed on both side walls in the main scanning direction of the cover 54y.

  A pair of elastic pieces 54z are provided on both side walls in the main scanning direction of the cover 54y. Each elastic piece 54z is a member that is elongated in the transport direction D, and both ends in the transport direction D are fixed to the outer surface of the side wall in the main scanning direction of the cover 54y, and can be elastically deformed at portions other than both ends in the transport direction D. The elastic portion 54z1 is provided. The elastic portion 54z1 can be displaced in the main scanning direction.

  A convex portion 54z2 that can be fitted into any of the concave portions 53z (see FIG. 1) of the tray main body 53 is formed on the outer surface of each elastic portion 54z1. The convex portion 54z2 protrudes outward in the main scanning direction from the outer surface of each elastic portion 54z1. The convex portion 54z2 is configured to be able to take a fitting position where the convex portion 54z1 is fitted into the concave portion 53z and a backward position where the convex portion 54z is retracted according to the elastic deformation of the elastic portion 54z1.

  With the pair of springs 56 attached to both ends of the rotation shaft 55x in the main scanning direction, the rotation shaft 55x is supported by the bearing 54x1 of the bottom plate 54x, and then the cover 54y is covered, and the two fixing pins 57 are attached to the bottom plate 54x. Inserted into the two through holes 54x2 formed in the bottom plate 54x and the two cylindrical holes 54y2 provided in the base 54 from the lower surface side. Thereby, the base 54 and the stopper 55 are assembled together.

  The stopper 55 is rotated with respect to the base 54 so that the end surface 55y1 on the upstream side in the transport direction D of the stopper body 55y faces the end in the transport direction D of the paper P received by the receiving surface 53a ( A position indicated by a solid line in FIG. 6C) and a rotational position where the angle α between the end face 55y1 and the receiving surface 53a is larger than that at the stopper position (a position indicated by a two-dot chain line in FIG. 6C). Can take.

  The pair of springs 56 urges the stopper 55 in the direction from the rotation position toward the stopper position.

  A pair of protrusions 55x2 is provided at both ends of the rotation shaft 55x in the main scanning direction. Each protrusion 55x2 has a main portion from both sides of the rotation axis 55x in the main scanning direction from a substantially half region on the side where the stopper main body 55y is fixed in a cross section in a direction perpendicular to the main scanning direction of the rotation shaft 55x. Projecting outward in the scanning direction.

  Each protrusion 55x2 extends to the outside of the cover 54y through each through hole 54y1 (see FIGS. 6A and 6B). The end surface in the protruding direction of each protruding portion 55x2 overlaps the inner surface of each elastic portion 54z1 in the main scanning direction.

  Each protrusion 55x2 does not overlap with each elastic portion 54z1 when viewed from the main scanning direction when the stopper 55 is in the stopper position (see the solid line in FIG. 6C), and the stopper 55 is moved from the stopper position to the rotation position. When shifting, it partially overlaps each elastic portion 54z1 when viewed from the main scanning direction (see FIG. 6C and FIGS. 7A to 7C). That is, each protrusion 55x2 does not contact each elastic portion 54z1 when the stopper 55 is in the stopper position, and contacts each elastic portion 54z1 when the stopper 55 shifts from the stopper position to the rotation position.

  When the stopper 55 moves from the stopper position to the rotation position, the elastic portions 54z1 are restricted from elastic deformation by the protrusions 55x2 coming into contact with the elastic portions 54z1. Thereby, each convex part 54z2 is hold | maintained in the fitting position which fits into the recessed part 53z (refer FIG. 1), and the movement of the conveyance direction D with respect to the tray main body 53 of the base 54 is controlled. Thus, each protrusion 55x2 regulates the movement of the base 54 in the transport direction D with respect to the tray body 53 in cooperation with each protrusion 54z2 when the stopper 55 moves from the stopper position to the rotation position. .

  Further, each protrusion 55x2 comes into contact with each elastic portion 54z1 as soon as the stopper 55 starts to move from the stopper position to the rotation position when the stopper 55 moves from the stopper position to the rotation position, and then each elastic portion It is kept in contact with 54z1. That is, the restricting force for restricting the movement of the base 54 by each projecting portion changes binaryly when the stopper 55 takes the stopper position and when the stopper 55 takes the rotation position.

  As described above, according to the present embodiment, the receiving trays 52 a to 52 d are attached to the base 54 so as to be movable in the transport direction D, and are attached to the base 54 so as to be rotatable. The user can take out the paper P received in the receiving trays 52a to 52d in the transport direction D by adopting the configuration including the stopper 55. Furthermore, the problem that the base 54 moves relative to the tray main body 53 can be suppressed by providing the movement restricting mechanism (the pair of projecting portions 55x2).

  The movement restricting mechanism (the pair of projecting portions 55x2) conveys the base 54 to the tray body 53 in cooperation with the positioning mechanism (the pair of convex portions 54z2) when the stopper 55 moves from the stopper position to the rotating position. The movement in the direction D is restricted (see FIG. 6C and FIGS. 7A to 7C). In this case, since the movement restriction mechanism cooperates with the positioning mechanism to restrict the movement of the base 54, the structure of the movement restriction mechanism can be simplified.

  The movement restricting mechanism (the pair of projecting portions 55x2) is such that the restricting force for restricting the movement of the base 54 changes in a binary manner when the stopper 55 takes the stopper position and when the stopper 55 takes the rotation position. It is configured. In this case, the movement restriction of the base 54 accompanying the rotation of the stopper 55 can be quickly performed.

  Each of the receiving trays 52a to 52d further includes a pair of springs 56 that urge the stopper 55 in the direction from the rotation position toward the stopper position. In this case, after the stopper 55 is moved from the stopper position to the rotation position and the paper P is taken out, the stopper 55 is returned from the rotation position to the stopper position by the bias of the pair of springs 56. This eliminates the need for the user to return the stopper 55 from the rotation position to the stopper position.

  A pair of convex portions 54z2 constituting a positioning mechanism (a mechanism for positioning the base 54 with respect to the tray main body 53) is formed on each of the pair of elastic portions 54z1 provided on the base 54. Each convex portion 54z2 can take a fitting position that fits into the concave portion 53z (see FIG. 1) of the tray main body 53 and a retracted position that retreats from the concave portion 53z in accordance with the elastic deformation of each elastic portion 54z1. It is configured. The movement restricting mechanism (the pair of projecting portions 55x2) is configured to abut against the pair of elastic portions 54z1 and restrict elastic deformation of the elastic portion 54z1 when the stopper 55 moves from the stopper position to the rotating position. Yes. In this case, the configuration can be simplified as compared with the case where an electrical mechanism or the like is used.

  For the receiving trays 52a to 52d, a regulating member (supporting member 51) that regulates the removal of the paper P from the receiving surface 53a in the main scanning direction is provided. In this case, the paper P received in the receiving trays 52a to 52d is difficult to take out in the main scanning direction because of the restriction member, and is taken out in the transport direction D. At this time, the stopper 55 can be an obstacle, but it is easy to take out the paper P in the transport direction D by adopting a configuration in which the stopper 55 rotates with respect to the base 54.

  Next, a second embodiment of the present invention will be described with reference to FIGS. The printer according to the second embodiment is the same as the printer according to the first embodiment except for the configuration of the base and stopper, which is different from the printer according to the first embodiment.

  In the stopper 255 according to the present embodiment, the rotation shaft 55x does not have a pair of protrusions 55x2 (see FIGS. 4 to 7) but has a cam portion 255x2 (see FIG. 9). The cam portion 255x2 is provided at a portion other than the portion to which the stopper main body 55y is fixed at the center of the rotation shaft 55x in the main scanning direction.

  In the base 254 according to the present embodiment, a pair of through holes 54y1 into which the rotation shaft 55x is inserted are not formed on both side walls in the main scanning direction of the cover 54y. Further, the pair of elastic pieces 54z are not provided on both side walls in the main scanning direction of the cover 54y, and the elastic pieces 254z are provided on the bottom plate 54x. The elastic piece 254z is formed by providing a pair of slits extending in the transport direction D at the center of the bottom plate 54x in the main scanning direction and downstream of the transport direction D, and can be displaced in the vertical direction.

  On the lower surface of the tip of the elastic piece 254z (downstream end in the transport direction D), a recess (not shown) in the tray main body 53 is formed on the bottom surface of the tray main body 53 that defines the depression 53y. A plurality of recesses are formed along the projections 254z2 that can be fitted to each other. The convex portion 254z2 protrudes downward from the lower surface of the tip of the elastic piece 254z. The convex portion 254z2 is configured to be able to take a fitting position that fits into the concave portion and a retracted position that retreats from the concave portion in accordance with the elastic deformation of the elastic piece 254z.

  The stopper 255 is rotated with respect to the base 254 so that the end surface 55y1 on the upstream side in the transport direction D of the stopper main body 55y faces the end in the transport direction D of the paper P received by the receiving surface 53a ( 10 (c), and a rotation position where the angle α between the end face 55y1 and the receiving surface 53a is larger than that at the stopper position (position shown by a two-dot chain line in FIG. 10 (c)). Can take.

  The pair of springs 56 urges the stopper 255 in a direction from the rotation position toward the stopper position.

  The cam portion 255x2 does not contact the elastic piece 254z when the stopper 255 is at the stopper position, and contacts the elastic piece 254z when the stopper 255 shifts from the stopper position to the rotation position.

  When the stopper 255 moves from the stopper position to the rotation position, the cam portion 255x2 comes into contact with the elastic piece 254z, so that elastic deformation of the elastic piece 254z is restricted. Thereby, the convex portion 254z2 is held at the fitting position where the convex portion 254z2 is fitted into the concave portion (not shown), and the movement of the base 254 in the transport direction D with respect to the tray body 53 is restricted. As described above, the cam portion 255x2 regulates the movement of the base 254 in the transport direction D with respect to the tray main body 53 in cooperation with the convex portion 254z2 when the stopper 255 shifts from the stopper position to the rotation position.

  Further, when the stopper 255 moves from the stopper position to the rotation position, the convex portion 254z2 does not contact the elastic piece 254z until the stopper 255 reaches the rotation position, and the stopper 255 reaches the rotation position. The elastic piece 254z comes into contact with substantially the same time. That is, the regulating force for regulating the movement of the base 254 by the convex portion 254z2 changes in a binary manner when the stopper 255 takes the stopper position and when the stopper 255 takes the rotation position.

  As described above, according to the present embodiment, by providing the movement restricting mechanism (cam portion 255x2), the problem that the base 254 moves relative to the tray main body 53 is suppressed as in the first embodiment. can do. In addition, the same effect as that of the first embodiment can be obtained by the same configuration as that of the first embodiment.
