Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention relates to a receiver for receiving a recording medium which has been discharged from a recording apparatus, and also relates to a recording apparatus provided with this receiver.  
           [0002]    As a printer which is a kind of recording apparatus, there has been a large size printer which can form print on a recording medium having a relatively large size, for example, rolled paper used for printing and having a width of an A0 size or B0 size according to the JIS (Japanese Industrial Standard) standard. In case of such a large size printer, the rolled paper on which printing has been performed is usually received by a discharged paper receiver which is located below a printer body. This discharged paper receiver is constructed in such a manner that the rolled paper which has been cut to have a relatively short length may be received behind the printer, because the cut sheets can be stacked, while the rolled paper which has been cut to have a relatively long length may be received in front of the printer body so that the cut sheets can be immediately taken out.  
           [0003]    The discharged paper receiver as described above is provided in a form projecting forward and backward from the printer body, in order to cope with the rolled paper of a relatively large size. For this reason, the discharged paper receiver may become an obstacle when the printer is to be moved, and therefore, on occasion of transporting the printer, it has been necessary to dismount the discharged paper receiver from the printer, which has been annoying. On the other hand, there has been a discharged paper receiver of such a type that a cloth may be spread or folded according to modes for use, and further, locking positions of rod members for forming a framework of the cloth may be varied. However, this type of the receiver has had a complicated structure and has required annoying works.  
         SUMMARY OF THE INVENTION  
         [0004]    It is therefore an object of the invention to provide a receiver for a recording medium having a simple structure in which modes for use on occasion of transportation or on occasion of discharging the recording medium can be easily changed, and a recording apparatus provided with such a receiver.  
           [0005]    In order to achieve the above object, according to the invention, there is provided a receiver for receiving a recording medium discharged from a recording apparatus, the receiver comprising:  
           [0006]    a pivotable receiving member, which receives the recording medium; and  
           [0007]    a pivotable supporting member, which supports the receiving member so as to place one of a plurality of pivoting angles of the receiving member respectively associated with a plurality of using modes of the receiver.  
           [0008]    It is preferable that: a first end portion of the supporting member serves as a first pivot center of the supporting member while supporting a part of the receiving member which is other than a pivot center of the receiving member; and a second end portion of the supporting member serves as a second pivot center of the supporting member which is displaced in accordance with the using modes.  
           [0009]    Here, it is preferable that the receiver further comprises a guide member, which allows the displacement of the second end portion of the supporting member and holds the second end portion at one of a plurality of predetermined positions respectively associated with the predetermined pivoting angles of the receiving member.  
           [0010]    Here, it is preferable that the guide member includes a fixed member and a movable member which is usually placed at a stable position for holding the second end portion of the supporting member at one of the predetermined positions together with the fixed member, and is moved from the stable position for allowing the displacement of the second end portion of the supporting member.  
           [0011]    Here, it is preferable that the guide member includes an elastic member which urges the movable member toward the stable position, so that the movable member is moved against an urging force of the elastic member when the displacement of the second end portion of the supporting member is allowed.  
           [0012]    Further, it is preferable that the guide member includes a guide portion formed with a plurality of recesses which are associated with the respective predetermined positions and a passage interconnecting the recesses through which the second end portion of the supporting member is displaced.  
           [0013]    According to the invention, there is also provided a recording apparatus, comprising:  
           [0014]    a feeding section, from which a recording medium is fed;  
           [0015]    a recording section, at which information is recorded on the recording medium, the recording section arranged below the feeding section;  
           [0016]    a discharging section, from which the recording medium on which recoding has been performed is discharged, the discharging section arranged below the recording section; and  
           [0017]    a leg section, in which the receiver as set forth in claim 1 is provided, the leg section arranged below the discharging section.  
           [0018]    Preferably, the receiving member is pivotable between a substantially horizontal position and a substantially vertical position at a front side of the recording apparatus.  
           [0019]    Preferably, the using modes includes a first mode selected when the recording medium is fed back to the feeding section, a second mode selected when the recording medium is mounted onto the feeding section, and a plurality of receiving modes selected in accordance with conditions of the recording.  
           [0020]    Preferably, a first end portion of the receiving member is supported by the leg section as a pivot center, and a second end portion of the receiving member is adapted to be actuated by a user to select one of the predetermined pivoting angles of the receiving member.  
           [0021]    In the above configurations, the receiver can be of a simple structure essentially including a receiving member and a supporting member. Therefore, it is possible to cope with not only the mode for use on occasion of discharging the recording medium but also the mode for use on occasion of transporting the recording apparatus, only by setting a plurality of predetermined pivoting angles in which the receiving member is supported by the supporting member.

The spindle  113  is designed in such a manner that after the rolled paper has been mounted on a middle part of the spindle, both ends of the spindle  113  are received in the spindle receivers  114 ,  115  and axially supported so as to be rotated. The cover  112  for the rolled paper is rotatably supported at its upper part, and adapted to be opened or closed by lifting its lower part by hand or pushing it down.  
         [0047]    As shown in FIG. 2, the printing section  120  includes: a carriage  122  carrying a printing head  121  in a main scanning direction; a flexible flat cable (hereinafter referred to as FFC)  123  connecting the printing head  121  to a not shown controller for conducting the printing; an ink tube  124  connecting the printing head  121  to a not shown ink cartridge unit containing ink therein; a not shown paper feeding roller for feeding the rolled paper in a subscanning direction; and a not shown paper sucker for preventing the rolled paper from floating up from the paper feeding path. In addition, an upper cover  125  and a front cover  126  are attached to an upper face and a front face of the printing section  120  so as to cover the printing head  121 , the carriage  122 , and so on.  
         [0048]    The printing head  121  includes a black ink printing head from which black ink is ejected, and a plurality of color ink printing heads from which inks in various colors such as yellow, light cyan, cyan, light magenta, magenta, etc. are ejected. Further, the printing head  121  is provided with pressure generating chambers and nozzle orifices communicated with the pressure generating chambers. Ink contained in each pressure generating chamber is pressurized so that an ink drop of a controlled size can be ejected from an associated nozzle orifice onto the rolled paper.  
         [0049]    As shown in FIG. 2, the carriage  122  is suspended by way of a roller from a rail  127  extending in the main scanning direction and coupled to a carriage belt  128  so that the carriage  122  is adapted to follow the movements of the carriage belt  128  and to perform reciprocal movements guided by the rail  127  when the carriage belt  128  is actuated by a not shown carriage actuator.  
         [0050]    The FFC  123  is connected to a connector of the controller at its one end and connected to a connector of the printing head  121  at the other end so as to transmit printing signals from the controller to the printing head  121 . There are provided the ink tubes  124  for the inks in various colors. Respective one ends of the ink tubes  124  are connected to the respective ink cartridges for the corresponding colors by way of a compressor (not shown), and the other ends of the ink tubes  124  are connected to the respective printing heads  121  for the corresponding colors.  
         [0051]    The ink tubes  124  are adapted to supply the various colors of ink, which have been pressurized by the compressor, from the ink cartridges to the printing heads  121 . The front cover  126  is pivotably supported at its lower part, and adapted to be opened or closed by pushing down its upper part by hand or lifting it up.  
         [0052]    The paper discharging section  130  includes: a paper discharging guide  131  which forms a part of the paper feeding path in the subscanning direction; and a paper discharging roller (not shown) for feeding the rolled paper in the subscanning direction. Moreover, on a right hand of the paper discharging section  130  as viewed from the front, there is provided a cartridge holder  150  which contains and holds the ink cartridges.  
         [0053]    The leg section  140  includes a pair of supporting posts  142  having rollers  141  for transportation, and a reinforcing rod  143  which is extended between these supporting posts  142 . The printer body is placed on the supporting posts  142  and fixed with screws.  
         [0054]    When the ink jet printer  100  having the above described structure starts to be used, at first, the spindle  113  which is a constituent of the rolled paper holder  111  will be taken out from the paper feeding section  110 , and then, as shown in FIG. 3, a paper retainer  113   a  which has been inserted over the spindle  113  will be drawn out from an end of the spindle  113 .  
         [0055]    Thereafter, as shown in FIG. 4, the one end of the spindle  113  will be inserted into an axial hole C of rolled paper R from its one end to pass through the axial hole, and as shown in FIG. 5, the one end of the axial hole C of the rolled paper R is fitted with a paper retainer  113   b  which has been inserted and fixed on the other end of the spindle  113 . Subsequently, the paper retainer  113   a  is inserted from the one end of the spindle  113  to be fitted in the other end of the axial hole C of the rolled paper R. In this manner, the rolled paper R is allowed to rotate with the spindle  113 .  
         [0056]    Then, as shown in FIG. 6, both ends of the spindle  113  having the rolled paper R inserted thereon are held with hands, and the spindle  113  is placed into a diagonally oriented state with respect to a back and forth direction of the ink jet printer  100 , in other words, in a state where the other end of the spindle  113  having the rolled paper R inserted thereon is directed toward one of the spindle receivers  114 .  
         [0057]    The spindle receiver  114  herein is so designed as to be pivoted in the horizontal direction, and respective recesses  114   a ,  115   a  of the spindle receivers  114 ,  115  for receiving the ends of the spindle  113  are usually opposed to each other. However, when the spindle  113  having the rolled paper R inserted thereon is to be mounted, one of the spindle receivers  114  will be pivoted forward to form an angle of about 45 degree with respect to the other spindle receiver  115 .  
         [0058]    Thereafter, the other end of the spindle  113  having the rolled paper R inserted thereon is hooked on the recess  114   a  of the one of the spindle receivers  114 , and this spindle receiver  114  is pivoted together with the spindle  113  having the rolled paper R inserted thereon. Then, the respective recesses  114   a ,  115   a  of the spindle receivers  114 ,  115  are brought into an opposed state, and the other end of the spindle  113  having the rolled paper R inserted thereon is hooked on the recess  115   a  of the other spindle receiver  115 . In this manner, the spindle  113  having the rolled paper R inserted thereon can be easily set in the paper feeding section  110 .  
         [0059]    Subsequently, as shown in FIG. 8, a leading end of the rolled paper R will be drawn out downward to pass through a paper feeding path in the printing section  120 , and is further passed through a paper feeding path in the paper discharging section  130 , as shown in FIG. 9. Then, the rolled paper R is rotated in a take-up direction as shown in FIG. 10, and the leading end of the rolled paper R is positioned at a marker M which is formed on the paper discharging guide  131 , for example. Thereafter, the ink jet printer  100  is actuated to eject ink drops while the rolled paper R is fed in the subscanning direction, while the printing head  121  is moved in the main scanning direction. The rolled paper is discharged after predetermined information has been printed on the rolled paper R.  
         [0060]    As shown in FIG. 11, a receiver  400  includes: a paper tray  410  positioned between the supporting posts  142  in the leg section  140  and adapted to receive the rolled paper; a tray hook  420  provided between the supporting posts  142  in the leg section  140  and below the paper tray  410  so as to support the paper tray  410 ; and hook guides  430  provided on inner side faces of the supporting posts  142  and adapted to guide the movement of the tray hook  420 .  
         [0061]    As shown in FIG. 12, the paper tray  410  includes: a plurality of J-shaped rod members  411  arranged in parallel with each other at a constant interval; a straight rod member  412  connecting respective rear ends of the rod members  411 , a cloth member  413  covering front ends of the rod members  411 , a straight rod member  414  connecting respective middle parts of the rod members  411  at their rear end sides, and a straight rod member  415  connecting respective middle parts of the rod members  411  at their front end sides.  
         [0062]    This paper tray  410  has such a structure, as shown in FIG. 11, that both ends of the straight rod member  414  are rotatably supported by bearings  416  (see FIG. 17) which are provided on the inner side faces of the supporting posts  142 , and both ends of the straight rod member  415  are rotatably supported by front ends of the tray hook  420 , so that the paper tray  410  can be pivoted about the rod member  414  in a direction of an arrow mark a (see FIGS.  18  to  20 ), in front of the leg section  140 . Thus, the paper tray  410  is adapted to receive the rolled paper inside a curved face formed of a plurality of the J-shaped rod members  411 .  
         [0063]    As shown in FIG. 13, the tray hook  420  includes a straight rod member  421 , and a pair of straight rod members  422  which are respectively provided at a right angle, near both ends  421   a  of this rod member  421 .

This tray hook  420  is arranged in such a manner, as shown in FIG. 11, that the both ends  421   a  of the straight rod member  421  are rotatably supported by the hook guides  430 , and the both ends of the straight rod member  415  of the paper tray  410  are rotatably fitted into the ring-like ends  422   a  of the rod members  422 , so that the tray hook  420  can be pivoted about the rod member  421  together with the paper tray  410 .  
         [0064]    As shown in FIG. 14, each of the hook guides  430  includes: a movable plate  431 ; a fixed plate  432 ; a twisted coil spring  433 ; a screw  434 ; and rivets  435 ,  436 . The movable plate  431  is formed with: an elongated hole  431   a  into which each end  421   a  of the straight rod member  421  of the tray hook  420  can be inserted so as to be movable therein; a substantially L-shaped hole  431   b  into which the screw  434  fitted into the twisted coil spring  433  is inserted; and substantially L-shaped holes  431   c ,  431   d  into which the rivets  435 ,  436  are inserted.  
         [0065]    The elongated hole  431   a  is formed longitudinally in a back and forth direction of the leg section  140 , the hole  431   b  and the hole  431   c  are formed at a rear side of the elongated hole  431   a , and the hole  431   d  is formed at a front side. The holes  431   b ,  431   c , and  431   d  are formed in such a manner that the screw  434  and the rivets  435 ,  436  may not interfere within a range in which the movable plate  431  can move, in other words, within a moving range of the end  421   a  of the rod member  421 .  
         [0066]    The fixed plate  432  is formed with: a cut-out  432   a  for guiding movement of the end  421   a  of the straight rod member  421  of the tray hook  420 ; a threaded hole  432   b  into which the screw  434  fitted into the twisted coil spring  433  is screwed; circular holes  432   c ,  432   d  into which the rivets  435 ,  436  are inserted so as to be fixed; and a hole  432   e  with which a rear end of the twisted coil spring  433  is fitted.  
         [0067]    The cut-out  432   a  is designed in such a manner that valleys are formed respectively at a first position  432 a 1 , a second position  432 a 2 , a third position  432 a 3  and a fourth position  432 a 4  in which the end of the rod member  421  is adapted to be positioned, and the positions  432 a 1 ,  432 a 2 ,  432 a 3  and  432 a 4  are connected by way of flat peaks. Accordingly, the end of the rod member  421  can travel from the valley at either of the positions  432 a 1 ,  432 a 2 ,  432 a 3  and  432 a 4 , by way of the peak through a slope part, to another valley at either of the positions  432 a 1 ,  432 a 2 ,  432 a 3  and  432 a 4 .  
         [0068]    These components are joined and assembled as the hook guide  430 , as shown in FIG. 15, through such processes that the movable plate  431  and the fixed plate  432  are overlapped, the twisted coil spring  433  is locked in the hole  432   e  at its rear end and hooked on an upper part of the movable plate  431  at its front end, the screw  434  which has been fitted into the twisted coil spring  433  is inserted into the hole  431   b  and screwed into the threaded hole  432   b , and the separated rivets  435 ,  436  are respectively inserted into the holes  431   c ,  431   d , through the circular holes  432   c ,  432   d.    
         [0069]    Then, the fixed plates  432  of the hook guide  430  shown in FIG. 15 and of the other hook guide  430  in symmetry therewith are fixed by screws to the inner side faces of the supporting posts  142  in the leg section  140 , as shown in FIG. 11, so as to rotatably support the both ends  421   a  of the rod member  421  of the tray hook  420 . Explanation will be made herein, referring to FIGS. 16A to  16 D, about actions of the hook guide  430  when the end  421   a  of the rod member  421  travels from the second position  432 a 2  to the third position  432 a 3 .  
         [0070]    As shown in FIG. 16A, when the end  421   a  of the rod member  421  is positioned at the second position  432 a 2 , the movable plate  431  is located in a lower position on the rightmost hand in the drawing, and the screw  434  and the rivets  435 ,  436  are located at upper positions on the leftmost hand in the drawing in the holes  431   b ,  431   c ,  431   d.    
         [0071]    Then, as shown in FIG. 16B, when the end  421   a  of the rod member  421  has started to move from the valley at the second position  432 a 2  to the slope part, the end  421   a  of the rod member  421  presses an inner peripheral face of the elongated hole  431   a , and the movable plate  431  is pushed upwardly to the left in the drawing. On this occasion, the screw  434  and the rivets  435 ,  436  are located at lower positions on the right hand in the drawing in the holes  431   b ,  431   c ,  431   d , while the front end of the twisted coil spring  433  is elastically deformed.  
         [0072]    Further, as shown in FIG. 16C, when the end  421   a  of the rod member  421  has moved along the slope part to arrive at the peak interconnecting the second position  432 a 2  and the third position  432 a 3 , the end  421   a  of the rod member  421  ceases to press the inner peripheral face of the elongated hole  431   a , and only the end  421   a  of the rod member  421  moves along the flat peak part. On this occasion, the movable plate  431  is located at the upper position on the leftmost hand in the drawing, the screw  434  and the rivets  435 ,  436  are located at lower positions on the rightmost hand in the drawing in the holes  431   b ,  431   c ,  431   d , while the front end of the twisted coil spring  433  is elastically deformed to a largest degree.  
         [0073]    Finally, as shown in FIG. 16D, when the end  421   a  of the rod member  421  has been detached from the flat peak part interconnecting the second position  432 a 2  and the third position  432 a 3 , since the movable plate  431  is pushed downward by restoring force of the front end of the twisted coil spring  433 , the end  421   a  of the rod member  421  is pressed by the inner peripheral face of the elongated hole  431   a  and falls in the valley at the third position  432 a 3  to be positioned there.  
         [0074]    When the end of the rod member  421  is positioned at the third position  432 a 3 , the movable plate  431  is located in the lower position on the rightmost hand in the drawing which is the same state as in FIG. 16A, and the screw  434  and the rivets  435 ,  436  are located at the upper positions on the leftmost hand in the drawing in the holes  431   b ,  431   c ,  431   d . The above described actions are also the same in those cases where the end  421   a  of the rod member  421  travels from the valley at either of the positions  432 a 1 ,  432 a 2 ,  432 a 3  and  432 a 4 , by way of the flat peak part through the slope part, to any other valley at either of the positions  432 a 1 ,  432 a 2 ,  432 a 3  and  432 a 4 .  
         [0075]    Modes for use of the receiver  400  will be described referring to FIGS.  17  to  20 . The mode for use as shown in FIG. 17 is a rolled paper taking-up mode. In this mode, the paper tray  410  is in a state where the front ends of the J-shaped rod members  411  are rather lifted, for example, at about 20 degree from the horizontal position, and the tray hook  420  is in a state where the ends  421   a  of the rod member  421  are positioned at the first position  432 a 1 .  
         [0076]    The mode for use as shown in FIG. 18 is a first receiving mode of the discharged paper, in which the rolled paper which has been discharged utilizing curl in the rolled paper will be received and stocked. In order to change the mode from the taking-up mode in FIG. 17 to the first receiving mode in FIG. 18, it is sufficient that a user grasps the front ends of the J-shaped rod members  411  of the paper tray  410  and lift them upward.  
         [0077]    In this manner, the paper tray  410  is pivoted upward about the rod member  414 . Following this movement, the one ends  421   a  of the rod members  422  of the tray hook  420  is pivoted upward. At the same time, the ends  421   a  of the rod member  421  is moved forward in a horizontal direction guided by the hook guides  430 , as described referring to FIGS. 16A to  16 D. Since the tray hook  420  is accordingly pivoted, the paper tray  410  is placed in a state where the front ends of the J-shaped rod members  411  are lifted, for example, at about 55 degree from the horizontal position, and the tray hook  420  will be in a state where the ends of the rod member  421  are positioned at the second position  432 a 2 .  
         [0078]    The mode for use as shown in FIG. 19 is a second receiving mode of the discharged paper. When a large volume of ink has been used for conducting printing such as solid printing, the curl of the rolled paper is lost, and there is an anxiety that the leading end of the rolled paper may be caught by the paper tray  410  and a clog of the paper may occur. In order to overcome the anxiety, the rolled paper should be forcibly stored by increasing degree of the pivoting angle of the paper tray  410  in this second receiving mode. In order to change the mode from the first receiving mode in FIG. 18 to the second receiving mode in FIG. 19, it is also sufficient that the user grasps the front ends of the J-shaped rod members  411  of the paper tray  410  and lift them upward. Resultantly, the paper tray  410  is placed in a state where the front ends of the J-shaped rod members  411  are further lifted, for example, at about 70 degree from the horizontal position, and the tray hook  420  is placed in a state where the ends  421   a  of the rod member  421  are positioned at the third position  432 a 3 .  
         [0079]    The mode for use as shown in FIG. 20 is a rolled paper mounting mode, in which a distance between a position at which the user is standing and the rolled paper holder  111  can be minimized, when the rolled paper is set. In order to change the mode from the second receiving mode in FIG. 19 to the mounting mode in FIG. 20, it is also sufficient that the user grasps the front ends of the J-shaped rod members  411  of the paper tray  410  and lift them upward. Resultantly, the paper tray  410  is placed in a state where the front ends of the J-shaped rod members  411  are substantially upright, for example, at about 85 degree from the horizontal position, and the tray hook  420  is placed in a state where the ends  421   a  of the rod member  421  are positioned at the fourth position  432 a 4 .  
         [0080]    After the user has grasped the front ends of the J-shaped rod members  411  of the paper tray  410  and lifted them upward, only by pulling them forward and thereafter by pushing them downward, the ends  421   a  of the rod member  421  is guided by the hook guides  430  to move backward in a horizontal direction. Therefore, contrary to the above, the mode can be shifted from the mounting mode in FIG. 20 to the second receiving mode in FIG. 19.  
         [0081]    In this embodiment, the case in which the receiver  400  is applied to the ink jet printer  100  has been described. However, the present invention is not limited to this embodiment, but the receiver  400  can be applied to printers of other types or facsimiles from which recording mediums are discharged.
