  However, in the case of a conventional sheet storage mechanism that stacks sheets in a horizontal or near-horizontal inclination state, a stacking space that is at least equal to or larger than the sheet area is required. For this reason, especially when the sheet is a large plate, the sheet stacking means inevitably becomes large, and the overall configuration of the apparatus becomes large. In addition, it is necessary to increase the rigidity of the sheet stacking means for increasing the size.

  On the other hand, the method of hanging and stacking sheets as described in Patent Document 1 can solve the problem of the stacking space. However, in the case of the conventional suspension system, the sheet to be fed is simply suspended from the bar member. For this reason, when sheets of different sizes are stacked and stacked, the sheets are likely to be misaligned and it is difficult to stack them in a uniform state. Furthermore, the sheet may be displaced from the sheet support rod, which may cause damage to the image on the sheet.

  The present invention has been made in view of such technical problems. SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet storage mechanism that can easily stack a plurality of sheets of different sizes when stacking sheets in a folded state that is folded in half. That is.

  The present invention relates to a sheet storage mechanism that stores a sheet discharged from a discharge port. The sheet storage mechanism according to the present invention includes a sheet support bar disposed on the downstream side in the delivery direction of the discharge port, and two contact members capable of contacting two locations of the sheet support bar. Therefore, in the state where the discharged sheet is locked to the sheet support bar by the contact member by alternately locking the two contact members to the sheet support bar in accordance with the amount of the sheet fed from the discharge port. It is suspended from the sheet support bar.

  According to the present invention, there is provided a sheet storage mechanism that can easily stack a plurality of sheets of different sizes when stacking sheets in a suspended state that is folded in half. The

Embodiments of the present invention will be specifically described below with reference to the drawings. Note that the same reference numerals denote the same or corresponding parts throughout the drawings.
(First embodiment)
FIG. 1 is a perspective view showing a state when the sheet guide is in the retracted position in the sheet storage mechanism according to the first embodiment of the present invention. FIG. 2 is a longitudinal sectional view of the center portion showing a state when the sheet guide is in the guide position in the sheet storage mechanism of FIG. FIG. 3 is a longitudinal sectional view of the central portion when the sheet guide of the sheet storage mechanism of FIG. 1 is in the retracted position. 1 to 3, the sheet storage mechanism 100 according to the present embodiment is connected to a recording apparatus 500. This embodiment shows a case where the recording apparatus 500 is a large-format ink jet printer. The recording apparatus 500 is an apparatus that records an image on roll paper, which is a continuous recording material, and includes recording means (recording head) 1, roll paper 3, paper feed mechanism 4, transport mechanism 5, and the like. ing. The recording apparatus 500 is fixed on the stand 13.

  A sheet (sheet-like recording material) 12 pulled out from the roll paper 3 is fed toward the recording head 1 by the paper feeding mechanism 4, and an image is recorded by the recording head 1 while being conveyed by the conveying mechanism 5. Is done. The recorded sheet 12 is sent out from the discharge port 6. Further, the recorded sheet 12 is cut into a predetermined length by the cutter 2 disposed inside the discharge port 6 and discharged from the discharge port 6. The illustrated outlet 6 has a lower side 6a extending a predetermined length in the delivery direction.

  The recording head 1 as recording means records an image (including characters and symbols) on a recording material based on image information. In the case of an ink jet type, a plurality of recording heads are recorded based on image information. Recording is performed by ejecting ink from the ejection port to the sheet. The recording material 12 has a sheet shape, and is simply referred to as a sheet below. As the material of the sheet, various materials can be used as long as they can record images, such as paper, plastic sheet, photographic printing paper, and leather.

  A sheet storage mechanism 100 for storing and holding discharged sheets is connected to the discharge port 6 of the recording apparatus 500. The sheet storage mechanism 100 is supported by a pair of left and right legs 8 and 9 connected to the stand 13 so as to be disposed at a predetermined position adjacent to the recording apparatus 500. The pair of legs 8 and 9 are erected with an interval slightly wider than the width of the sheet 12 (roll paper 3), and are connected by a stay 14 to form a highly rigid frame. Further, a seat support bar 7 (support bar) is arranged at an intermediate position between the pair of legs 8 and 9 so as to connect the legs on both sides. The sheet support bar 7 is a bar-shaped member for stacking the discharged sheets 12 in a suspended state. The sheet support bar 7 is arranged in parallel with the discharge port 6 at a predetermined position downstream of the discharge port 6 in the delivery direction. A sheet guide 11 as a guide member for guiding the discharged sheet 12 to the sheet support bar 7 is disposed between the discharge port 6 (extending portion 6 a) and the sheet support bar 7. The sheet guide 11 is movable to a first position where the sheet 12 is guided downstream in the sheet feeding direction of the sheet support bar 7 and a second position where the sheet guide 11 is guided upstream in the sheet feeding direction of the sheet support bar 7.

  The sheet guide 11 is a bearing provided on the left and right in the vicinity of the discharge port 6 and is movable between a guide position (first position) in FIG. 2 and a retracted position (second position) in FIG. Is pivotally supported. In the present embodiment, the position of the sheet guide 11 is controlled between the guide position and the retracted position in accordance with the feed amount of the sheet 12 being recorded. The sending amount in this case is obtained by detecting the length of the recorded sheet 12 sent from the discharge port 6. Flanges 15 and 16 are provided at both ends of the sheet support bar 7. Each of these flanges is provided with contact members 10 and 18 at two locations in the circumferential direction.

  The contact members 10 and 18 are supported so as to be movable (for example, turnable) between a contact position pressed against the peripheral surface of the sheet support bar 7 and a retracted position separated from the peripheral surface of the sheet support bar. Yes. When the abutting members 10 and 18 are in the abutting position, the sheet 12 is pressed against the sheet supporting rod 7 to be locked. In addition, each of the contact members 10 and 18 is controlled to take either the contact position or the retracted position in accordance with the feed amount of the sheet 12 being recorded. As described above, the sheet storage mechanism 100 of the present embodiment is provided with the two contact members 10 and 18 that can contact the two portions of the sheet support bar 7. In the present embodiment, one abutting member 10 (second abutting member) is used to lock the sheet 12 suspended on the sheet support bar 7 after the recording is completed to the sheet support bar. The other abutting member 18 (first abutting member) is used to form a sheet deflection required in the process of suspending the sheet 12 from the sheet support rod 7.

  Next, the configuration and operation of the sheet storage mechanism 100 according to the first embodiment will be described with reference to FIGS. In the state of FIG. 2, the sheet guide 11 is in a first position for guiding the discharged sheet 12 with a natural shape without bending, and the abutting member 10 locks (presses) the sheet 12 to the sheet support rod 7. At the contact position, the contact member 18 is at a retracted position where it does not contact the sheet 12. As shown in FIG. 2, the sheet 12 during or after the target image recording by the recording device 500 is discharged from the discharge port 6 and guided along the sheet guide 11 of the sheet storage mechanism 100. After that, it hangs down from the front end (downstream end) of the sheet guide 11. Then, the sheet is fed out along the circumferential surface on the downstream side (right side in the drawing) of the sheet support bar 7 in the sheet feeding direction.

  As the sheet 12 is fed out, an intermediate portion (for example, a substantially central portion) of a length where the target image recording of the sheet 12 is (or has been performed) reaches the sheet support bar 7. The sheet 12 in FIG. 2 shows a state where it reaches the half end of such a sheet length. The arrival of this position at the sheet support bar 7 can be detected based on the sheet feed amount and the image recording length. At the time when this is detected or immediately after this, the sheet guide 11 and the contact members 10, 18 are moved from the state of FIG. 2 to the state of FIG. In the state of FIG. 3, the sheet guide 11 has moved from the guide position to the retracted position, and one of the contact members 18 has moved from the retracted position to the contact position, and has been guided to the downstream side of the sheet support rod 7 of the sheet. Press the part against the sheet support bar. The other contact member 10 has moved from the contact position to the separated position.

  That is, in the present embodiment, the two contact members 10 and 18 are alternately engaged with the sheet support bar 7 in accordance with the amount of the sheet 12 fed from the discharge port 6. Further, by the operation of the contact members 10 and 18, the discharged sheet 12 is suspended from the sheet support bar while the discharged sheet 12 is locked to the sheet support bar 7 by the contact member 18. . In the present embodiment, a support member 19 having a mountain-shaped cross section for supporting the bottom portion of the sheet 12 suspended from the sheet support bar 7 is disposed below the sheet support bar 7.

  Specifically, the sheet guide 11 rotates downward about the discharge port 6 side according to the amount of the sheet 12 fed from the discharge port 6. As a result, the sheet guide 11 moves to the retracted position (second position), and a space for allowing the sheet 12 to hang down is formed between the discharge port 6 and the sheet support bar 7. Each contact member 10, 18 also rotates about its rotation axis. Here, the contact member 18 moves to a contact position where the sheet 12 is locked to the sheet support rod 7, and the contact member 10 moves to a retracted position where it does not contact the sheet 12. In this way, in the state shown in FIG. 3, the sheet 12 is locked on the sheet support rod 7 by the contact member 18, so that even if recording is continued, the sheet 12 does not move from the contact member 18 to the portion ahead. . For this reason, only the amount of sheet deflection 17 formed between the discharge port 6 and the sheet support bar 7 increases.

  Further, when the target image recording is completed, the rear end of the sheet 12 is cut by the cutter 2. As a result, the rear end of the sheet 12 slides down from the discharge port 5 by its own weight to the upstream side of the sheet support bar 7, and the sheet 12 is stacked while being suspended from the sheet support bar 7 at the center portion. The operation when the sheets 12 are stacked on the sheet support bar 7 is substantially the same when the sheets are cut before the sheet guide 11 moves to the retracted position. Here, when the recording operation is finished, the operation of the sheet storage mechanism 100 may be finished, or the sheet guide 11 and the contact members 10 and 18 are returned to the state before the recording is started (the state shown in FIG. 2). May be. If there are continuous recording jobs, the sheet guide 11 and the contact members 10 and 18 are returned from the state of FIG. 3 to the state of FIG. 2 while continuing the job.

  In the state of FIG. 2, the contact member 10 stops at a contact position where the sheet 12 is locked to the sheet support rod 7, and the contact member 18 stops at a retracted position where the sheet 12 does not contact the sheet 12. Further, in the state of FIG. 2, the sheet 12 is locked by the contact member 10. For this reason, the stacked sheets can be held at a fixed position, and even if the next sheet hangs down from the leading end of the sheet guide 11 to the sheet support bar 7 and moves along the surface of the stacked sheets, The stacked sheets do not move or shift. The next sheet can also be stacked in a stable suspended state. In the present embodiment, the sheet 12 suspended from the sheet support bar 7 is supported by a chevron-shaped support member 19 at the skirt portion.

  As described above, in the present embodiment, the two contact members 10 and 18 are alternately engaged with the sheet support bar 7 in accordance with the amount of the sheet 12 fed from the discharge port 6. Accordingly, the discharged sheet is suspended from the sheet support bar in a state where the discharged sheet is locked to the sheet support bar by the contact member. That is, the two abutting members 10 and 18 are alternately brought into contact with the sheet support bar 7 in accordance with the length of the discharged sheet 12, thereby supporting the discharged sheet at the intermediate portion in the length direction. It is configured to be suspended from the rod 7. As a result, when the sheets 12 are stacked in a suspended state that is folded in two, even when a plurality of sheets of different sizes are stacked, it is possible to easily stack them in a uniform state.

FIG. 4 is a perspective view of the sheet guide of the sheet storage mechanism according to the second embodiment of the present invention. FIG. 5 is a longitudinal sectional view of the central portion when the sheet guide is in the guide position in the sheet storage mechanism of FIG. FIG. 6 is a longitudinal sectional view of the central portion when the sheet guide is in the retracted position in the sheet storage mechanism of FIG. The sheet storage mechanism 200 according to the second embodiment is different from the sheet storage mechanism 100 according to the first embodiment in the configuration of an abutting member for locking the sheet 12 to the sheet support bar 7. The configuration is substantially the same.

  4 to 6, the sheet storage mechanism 200 is disposed on the pair of legs 20 and 21 so as to be connected to the discharge port 6 for discharging the sheet 12 from the recording apparatus 500. These legs 20 and 21 are connected to a stand 13 that supports the recording apparatus 500. A frame having high rigidity is configured by connecting the left and right legs 20 and 21 with a stay 14. A sheet support bar 22 is arranged in a posture parallel to the discharge port 6 so as to connect intermediate portions of the left and right legs 20 and 21. A sheet guide 11 for guiding the fed sheet 12 to the sheet support bar 22 is disposed between the discharge port 6 (its extending portion 6 a) and the sheet support bar 22. Abutting members 24 and 25 are disposed at two locations in the vicinity of the sheet support rod 22 that are substantially opposite to each other in the front-rear direction. Each of the contact members 24 and 25 has a configuration in which a pressing cylindrical portion 27 is disposed at a plurality of positions (two locations in the illustrated example) in the length direction of a shaft 26 extending in parallel with the sheet support rod 22.

  One abutting member 24 is supported so as to be movable along the guide groove 29 by fitting the both ends of the shaft 26 to the guide grooves 29 formed on the legs 20 and 21 on both sides in a slidable manner. ing. That is, the contact member 24 is movable along the guide groove 29, and the contact position (FIG. 6) where the cylindrical portion 27 is pressed against the sheet support bar 22 and the retreat position (FIG. 5) away from the sheet support bar. ) Is supported so as to be movable between. The other abutting member 25 is supported so as to be movable along the guide groove 30 by fitting both end portions of the shaft 26 to the guide grooves 30 formed on the legs 20 and 21 on both sides in a slidable manner. ing. Each guide groove 30 is formed in an arm portion 20a, 21a extending to the rear of each leg 20, 21 (to the recording apparatus side). That is, the contact member 25 is movable along the guide groove 30, and a contact position (FIG. 5) where the cylindrical portion 27 is pressed against the sheet support bar 22 and a retreat position (FIG. 6) away from the sheet support bar. ) Is supported so as to be movable between.

  The movement and stop positions of the contact members 24 and 25 are controlled in accordance with the amount of the sheet 12 sent out from the discharge port 6. In particular, in the present embodiment, the contact members 24 and 25 are arranged so as to be movable while maintaining a parallel posture with respect to the sheet support bar 22. The contact members 24 and 25 can lock the sheet 12 to the sheet support rod 22 when in the contact position. In this case, like the contact member 10 in the first embodiment, the one contact member 25 is used to lock the sheet 12 suspended from the sheet support rod 22 after the storage operation is completed to the sheet support rod. Is done. The other abutting member 24 is used to form the sheet deflection 17 required in the process of suspending the sheet 12 on the sheet support rod 22, as in the abutting member 18 in the first embodiment. The sheet storage mechanism 200 according to the second embodiment has the same configuration as that of the first embodiment described above except for the points described above. Accordingly, corresponding portions are denoted by the same reference numerals, and detailed description thereof is omitted.

  Next, the operation of the sheet storage mechanism 200 according to the second embodiment will be described with reference to FIGS. In the state of FIG. 5, the sheet guide 11 is in a position for guiding the fed sheet 12 with a natural shape without bending, the contact member 24 is in a retracted position separated from the sheet support bar 22, and the contact member 25 is in the sheet. The contact position is in contact with the support rod 22. As shown in FIG. 5, the sheet 12 during or after the target image recording by the recording device 500 is sent out from the discharge port 6 and guided along the sheet guide 11, and then the leading edge thereof. It hangs down from the club. Then, the sheet is fed out along the peripheral surface on the front end side (right side in the drawing) of the sheet support bar 22.

  As the sheet 12 is fed out, the substantially central portion of the length of the sheet 12 on which the target image recording is performed (or performed) is reached on the sheet support bar 22. The sheet 12 in FIG. 5 shows a state where it reaches the half end of such a sheet length. The fact that the position of approximately half of the target image recording length has reached the sheet support bar 22 can be detected based on the sheet feed amount and the image recording length. When this is detected, or immediately after this, the sheet guide 11 and the contact members 24 and 25 are moved from the state of FIG. 5 to the state of FIG. That is, the sheet guide 11 is moved from the guide position to the retracted position, one contact member 24 is retracted from the contact position to the separated position, and the other contact member 25 is moved from the retracted position to the contact position.

  Specifically, when the sheet guide 11 rotates downward, a space for allowing the sheet 12 to hang down is formed between the discharge port 6 and the sheet support rod 22. The contact member 24 moves along the guide groove 29 to a contact position where the sheet 12 is locked to the sheet support rod 22. The contact member 25 moves along the guide groove 30 to a retracted position separated from the sheet support bar 22. The guide grooves 29 and 30 are formed in the legs 20 and 21 on both sides, respectively. In particular, the guide groove 30 is formed in each of the substantially horizontal arm portions 20 a and 21 a of the legs 20 and 21. In the state shown in FIG. 6, since the sheet 12 is locked on the sheet support rod 22 by the contact member 24, even if the sheet 12 continues to be fed along with the recording operation, the sheet contact It does not move in the part ahead of the member 24. For this reason, the amount of sheet deflection 17 formed between the discharge port 6 and the sheet support rod 22 increases.

  Further, when the target image recording is completed, the rear end of the sheet 12 is cut by the cutter 2. As a result, the rear end of the sheet 12 slides down due to its own weight from the discharge port 5, and the sheet 12 is folded in half and is suspended from the sheet support bar 22 at the intermediate portion and stacked. The operation when stacking the sheet 12 on the sheet support bar 22 is substantially the same when the sheet is cut by the cutter 2 before the sheet guide 11 moves to the retracted position. Further, when the recording operation is finished here, the operation of the sheet storage mechanism 200 may be finished as it is, or the state of the sheet guide 11 and the contact members 24 and 25 before the start of recording (state of FIG. 5). You may go back up. If there are continuous recording jobs, the sheet guide 11 and the contact members 24 and 25 are returned from the state of FIG. 6 to the state of FIG. 5 while continuing the job.

  In the state of FIG. 5, the contact member 25 stops at the contact position where the contact member 25 contacts the sheet support bar 22, and the contact member 24 stops at the retracted position separated from the sheet support bar 22. In the state of FIG. 5, the stacked sheets 12 are locked to the sheet support bar 22 by the contact member 25. For this reason, the stacked sheets can be held in a fixed position, and the next sheet is hung from the leading end portion of the sheet guide 11 to the sheet support bar 22 and moved along the surface of the stacked sheets. The sheet does not move or shift. Further, the next sheet can be stacked in a stable state as described above.

  As described above, also in this embodiment, the two contact members 10 and 18 are alternately engaged with the sheet support bar 7 in accordance with the amount of the sheet 12 fed from the discharge port 6. Accordingly, the discharged sheet is suspended from the sheet support bar in a state where the discharged sheet is locked to the sheet support bar by the contact member. That is, the two abutting members 10 and 18 are alternately brought into contact with the sheet support bar 7 in accordance with the length of the discharged sheet 12, whereby the discharged sheet is folded in half at the intermediate portion in the length direction. It is configured to be suspended from the sheet support bar 7 in a state. As a result, when the sheets 12 are suspended and stacked in a folded state, even when a plurality of sheets having different sizes are stacked, it is possible to easily stack them in a uniform state.

  Further, according to the sheet storage mechanism according to each of the embodiments described above, the discharged recorded sheet can be stored in an unfolded state. Note that the conventional sheet storage mechanism that stacks horizontally or nearly horizontally on the sheet discharge tray requires a storage space that is equal to or larger than the sheet area. On the other hand, according to the above-described embodiments, the sheet 12 can be collected in a state of being suspended in a substantially inverted U shape on the sheet support rods 7 and 22, so that a place like a storage tray is not required. Therefore, it is possible to reduce the size of a device that uses the sheet storage mechanism. Further, the recorded sheet can be collected without making a crease. Further, movable contact members 10, 18 or 24, 25 are provided at two locations as means for locking the sheets, and the stored sheets can be locked and stacked by either one of the contact members. . For this reason, even a plurality of sheets having different sizes can be held in a uniform stack without causing a deviation.

  In the above embodiment, the case where the sheet discharged from the recording apparatus is stored using the sheet storage mechanism according to the present invention has been described as an example. However, the sheet storage mechanism according to the present invention is not limited to this, and can be widely applied to storing sheets discharged from devices other than the recording apparatus as long as the devices handle sheets.
