  A conventional medium storage structure has a front guide plate, a rear guide plate facing the front guide plate, a pair of side plates provided on the sides of the front guide plate and the rear guide plate, a top plate, and a bottom plate to form a storage space. A body, a feed roller disposed at a medium carry-in port provided on the front guide plate, a separation roller disposed opposite to the bottom plate side of the feed roller, and a rotation shaft of the separation roller attached to the rotating shaft via a one-way clutch, A stacking mechanism having a tongue piece roller provided with a tongue piece, a stage which is provided between the top plate and the bottom plate so as to be movable up and down, and stacks and stacks paper-like media in the thickness direction; A medium that is provided with an upper surface detection sensor that detects the upper surface of the medium on the front guide plate side, and that is rotated by causing the tip of the tongue piece roller provided on the rotation shaft of the separation roller to rotate from the front guide plate. Trailing edge If the upper surface detection sensor detects the upper surface of the medium when a certain number of mediums are accumulated, it is determined that the medium with strong bending is accumulated, and the medium is detected at the tip of the tongue piece. If the top edge sensor detects the top surface of the medium even if the trailing edge of the medium is detected even if the trailing edge of the medium is detected by pressing the rear edge of the medium, Therefore, the medium is continuously accumulated by lowering the stage by a certain amount (see, for example, Patent Document 1).

  In addition, a height detection lever is provided to detect the height of the central part of the medium loaded on the stage in the loading direction, and the stage lift is set according to the thickness and length of the loaded medium. Some media prevent reversal or jamming of the medium (see, for example, Patent Document 2).

JP 2009-046298 A (paragraphs 0011-0016, 0026, 0041-0044, FIGS. 6 and 8) JP-A-6-247606 (paragraphs 0013-0021, FIGS. 1 and 4)

  Generally, an automated teller machine installed in a branch of a financial institution such as a bank or a store such as a convenience store automatically performs transaction processing with a user, such as a transaction selection screen and various input screens. Operation display unit with a display screen for displaying, card unit for reading and writing the card information of the user's transaction card and issuing a statement slip, reading and writing the bankbook information of the user's bankbook, and writing the transaction contents in the bankbook A bankbook unit, a banknote unit for depositing / withdrawing banknotes, a coin unit for depositing / withdrawing coins, etc. are provided. In order to improve the operability of transactions for users, transaction card and bankbook insertion slot, operation display section Since the deposit / withdrawal port of banknotes and coins is concentrated on the front side, downsizing of each unit or the like is desired.

  In addition, some of the automatic teller machines installed at convenience stores, etc. include payment of water, gas, electricity, telephone charges, etc. brought by users and Yu-Pack (registered trademark of Japan Post Holdings Co., Ltd.). Some payment items, catalogs for mail-order sales, etc. and payment items for product prices that also serve as application forms attached to advertisements are read and payment transactions based on these items are automatically performed. .

  However, in the techniques of the above-described conventional Patent Document 1 and Patent Document 2, since the medium storage structure includes a stage that can be raised and lowered, it is possible to perform control for preventing the above-described jam generation. This raises the problem that it is difficult to reduce the size of the medium processing unit equipped with the medium storage, which requires a lifting device that lifts and lowers the size of the medium storage.

  For this reason, using a medium storage that directly stacks and stores media on the bottom plate of the housing, the height of the media accumulated and stored on the bottom plate is detected by an upper surface detection sensor or a height detection lever, If the movement of the automatic teller machine is stopped when it is detected that the stored medium is full, the medium processing unit equipped with the medium storage can be downsized.

  On the other hand, the payment documents issued by the above-mentioned operators are formed in a rectangle so that the insertion direction can be easily specified, and the length in the short side direction and the long side is a predetermined tolerance (for example, ± 1 mm). In the case of payments printed with a cut line on the catalog, such as payments attached to mail order catalogs, Due to a cutting mistake at the time of cutting, a non-standard payment document exceeding the upper limit of the standard tolerance may be inserted into the media processing unit.

  If such a non-standard payment document is inserted into the media processing unit and returned to the user, it will hinder the spread of automatic transactions using the payment document. Therefore, when handling non-standard payment documents is possible, when the payment document is stored in the media storage after the processing with non-standard payment documents is completed, When knocked down at the front end and accumulated on the bottom plate, the front end and rear end of the non-standard payment form will be in contact with the back guide plate and the front guide plate, respectively, and the center will be on the top plate side. A convex curved medium will be stored.

  In this case, as a means for detecting the full state, if a full detection lever for detecting the height of the central portion in the carry-in direction of the accumulated medium as in Patent Document 2 is used, the central portion is located on the top side in the housing. Even when a convex curved medium is stored, if the full detection lever detects the vicinity of the top of the curved medium, even if the number of stored sheets does not reach the predetermined number of sheets set in the medium storage There is a problem that the automatic teller machine stops moving due to a false detection of the full state, and the efficiency of the automatic teller machine decreases.

  This means that when the medium storage for storing processed payment documents is formed with a shallow housing, the full detection lever detects the full state when one curved medium is stored. This is a particular problem.

  In addition, even when the medium storage is formed with a deep bottom case, when the number of media already stored is small, the curved medium whose center is convex toward the top is stored Even if the full detection lever does not detect the full state, a force that crushes the central portion of the curved medium that is stretched by the medium stored on the full detection lever does not act, or the medium that has already been stored If the curved medium is stored when the number of sheets is large, the full detection lever detects the full state when the predetermined number of stored sheets set in the medium storage is not reached, and the above-described problem is solved. Will be generated.

  The present invention has been made to solve the above-described problems, and provides a medium storage structure that enables a non-standard medium exceeding the upper limit of the standard tolerance to be stored in a flat state on the bottom plate. For the purpose.

  In order to solve the above problems, the present invention provides a front guide plate, a rear guide plate facing the front guide plate, a pair of side plates provided on the sides of the front guide plate and the rear guide plate, A casing in which a storage space is formed by a top plate and a bottom plate, a feed roller disposed at a medium carry-in port provided in the front guide plate, and a pressure roller disposed to face the top plate side of the feed roller And a stacking mechanism fixed to a rotation shaft of the feed roller disposed in an axial direction perpendicular to the medium carrying-in direction, and a tongue piece roller provided with a plurality of tongue pieces, and the bottom plate A medium storage structure for storing media by stacking them directly in the thickness direction, wherein an outer peripheral surface of the feed roller on the back guide plate side protrudes from the front guide plate into the storage space, and is stored in the storage space. Protruding into Protrusions was, on both sides of the axial direction, characterized in that a guard portion having a guard surface disposed in the housing space side of the outer peripheral surface of the projecting portion.

  As a result, the present invention can form a recess between the feed roller and the bottom plate that allows the storage of non-standard payment documents exceeding the upper limit of the standard tolerance by the front guide plate and the guard surface of the guard part. Even if a non-standard payment note is carried in, the payment note can be stored directly on the bottom plate in a flat state.

  Further, in the following description, the print target medium is described as a payment document (hereinafter referred to as payment document S).

  The initial state of the full detection lever 43 and the backflow prevention lever 50 of the medium storage 26a of this embodiment is the state shown in FIG.

  When the user sets the payment document S in the medium insertion slot 7a of the medium processing unit 7, the control unit conveys the payment document S to the scanner unit 25 through the medium conveyance path 28, and the scanner unit 25 stores the payment document S. Read the entry.

  At this time, if the entry contents or the like cannot be read, the control unit reverses the conveyance roller 27, conveys the payment slip S to the medium insertion slot 7a, and returns it to the user.

  The control unit that has read the entry contents of the payment slip S transmits the entry content to a main control unit (not shown) of the automatic teller machine 1, and the main control unit communicates with a host computer (not shown) to fill in the payment slip S. When the payment transaction based on the contents is executed and the process of the payment transaction is completed, the main control unit transmits a print command attached with predetermined description contents such as the transaction date and time and the name of the transaction store to the control unit.

  The control unit that has received the print command conveys the payment statement S in the direction of the printing unit 18 through the medium conveyance path 28 in order to print the predetermined description content on the printing surface of the payment statement S.

  At this time, the rotation direction of the rotation shaft 36a of the feed roller 36 driven by a common drive source with the conveyance roller 27 of the medium conveyance path 28 is an anti-integration rotation direction, for example, as shown in FIG. 7 or FIG. In addition, when the payment slip S is already stored on the bottom plate 31e, the tongue piece roller 38 fixed to the rotating shaft 36a rotates in the anti-stacking rotation direction, so that the rear end portion of the stored payment slip S is It is lifted by the tip of the tongue piece 38a, and as the tongue piece 38a rotates in the anti-stacking rotation direction, the trailing end of the payment slip S is guided toward the medium carry-in port 33. The backflow prevention lever 50 having a receiving portion 50b disposed downstream in the carry-in direction of the holding portion of the feed roller 36 and the pressure roller 37 waits in a state where the engaging portion 50a is engaged with the stopper 51.

  Then, the control unit conveys the payment slip S from the medium conveyance path 28 to the print conveyance path 19, holds the payment slip S between the conveyance rollers 22, conveys it to a predetermined printing position on the platen 21, and stops printing. While moving the head 20 in the printing direction that is orthogonal to the conveying direction, the predetermined description content is printed on the payment slip S.

  The control unit that has finished printing on the payment slip S, when the payment slip S is a payment slip S that is relatively infrequent, uses the print transport path 19 of the print unit 18 and the medium transport path 28 of the medium processing unit 7. Each of the transport rollers 22 and 27 is reversed to transport the processed payment slip S in the direction of the medium insertion slot 7a, and the switching blade 29d switches the transport direction to the direction of the medium storage 26a and transports it to the medium storage 26a. Then, the front end in the conveyance direction of the payment slip S guided by the conveyance guide 32 is sandwiched between the feed roller 36 and the pressure roller 37.

  At the time of conveyance to the medium storage 26a, the rotation direction of the rotation shaft 36a of the feed roller 36 driven by a common driving source with the conveyance roller 27 of the medium conveyance path 28 is the accumulation rotation direction, and the tongue piece roller 38 also rotates in the direction of accumulation rotation.

  When the front end in the conveying direction of the payment slip S is sandwiched between the feed roller 36 and the pressure roller 37, the payment slip S is carried in the carry-in direction by the feed roller 36 rotating in the stacking rotation direction, and the front end 5 collides with the receiving portion 50b of the backflow prevention lever 50, as shown in FIG. 5, the backflow prevention lever 50 is pushed by the front end of the pay-in sheet S around the rotating shaft 37a of the pressure roller 37, and the receiving portion 50b is stored in the storage space. When the front end collides with the full detection lever 43, the full detection lever 43 is pushed by the front end of the pay-in sheet S around the rotation fulcrum 44 and is moved to the top plate 31d side. To turn.

  At this time, the detection plate 43b of the full detection lever 43 instantaneously interrupts the optical axis of the full detection sensor 46. However, the detection of the full state by the control unit of this embodiment is performed for a predetermined time. Since it is determined by being interrupted, a false detection of a full state does not occur.

  Then, when the nipping of the payment slip S by the feed roller 36 and the pressure roller 37 is released, the payment slip S is discharged from the medium carry-in port 33 to the storage space 34 as shown in FIG. It collides with the plate 31b and falls on the bottom plate 31e while being struck by the tip of the tongue piece 38a of the tongue piece roller 38 rotating in the stacking rotation direction.

  At this time, the backflow prevention lever 50 and the full detection lever 43 are rotated in the direction of the stopper 51 and the support portion 45a by their own weights.

  In addition, since the guard surface of the guard portion 41 of the present embodiment is disposed on the storage space 34 side of the protruding portion of the feed roller 36 from the front guide plate 31a, the trailing end of the payment slip S contacts the feed roller 34. It will not be involved.

  Further, the tip end portion of the tongue piece 38a rotates while projecting from the opposing surface 41a of the guard portion 41, and the distance L1 between the opposing surface 41a and the rear guide plate 31b is a predetermined margin above the upper limit of the standard tolerance of the payment slip 3 Since it is formed at a distance including the allowance, the rear end portion of the payment slip S discharged from the medium carry-in port 33 can be reliably knocked down by the front end portion of the tongue piece 38a.

  As shown in FIG. 7, the payment slip S dropped on the bottom plate 31e of the storage space 34 is drawn toward the front guide plate 31a by the frictional force with the tip of the tongue piece 38a sliding on the rear end. The rear end abuts on the front guide plate 31a and is aligned.

  By such a storing operation, while the processed payment slip S within the standard is being collected and stored on the bottom plate 31e, the processed payment slip S (payment slip Sg and non-standard exceeding the upper limit of the standard tolerance) is stored. In the same manner as described with reference to FIGS. 5 and 6, the pay-in slip Sg is transferred to the backflow prevention lever 50 and the full detection lever 43 at the front end. It is discharged into the storage space 34 while being pushed away, and falls on the bottom plate 31e or on the uppermost payment slip S already stored while the rear end of the tongue piece 38a is struck.

  At this time, the distance L2 between the front guide plate 31a and the back guide plate 31b of the present embodiment is formed by a distance obtained by adding a predetermined margin to the length of the longest non-standard payment slip Sg. Therefore, the front end and the rear end of the non-standard payment slip Sg dropped on the bottom plate 31e or the topmost payment slip S are not stretched in a state where they are in contact with the front guide plate 31a and the rear guide plate 31b, respectively. In the full state, the central portion of the pay-in slip Sg in the carry-in direction is prevented from being convexly curved toward the top plate 31d, and the top of the curved pay-in slip Sg pushes up the detection portion 43a of the full detection lever 43. False detection can be prevented.

  As shown in FIG. 8, the pay-in slip Sg dropped on the bottom plate 31e of the storage space 34 is drawn in the direction of the front guide plate 31a by the frictional force with the front end portion of the tongue piece 38a sliding on the rear end portion. Then, like the payment slip S within the standard, the rear end is brought into contact with the front guide plate 31a in a flat state and is aligned.

  In this case, since the tip of the tongue piece 38a of the tongue piece roller 38 provided with the shallow medium storage 26a is configured to slide on the bottom plate 31e, it is discharged into the empty storage space 34. Even if the first payment slip S is a non-standard payment slip Sg, the tip of the tongue piece 38a slides on the rear end of the payment slip Sg, and the rear end of the payment slip Sg is flat. Can be stored in a state of being in contact with the front guide plate 31a.

  In this way, the payment slip S within the standard and the payment slip Sg outside the standard are sequentially stored on the bottom plate 31e, and the storage height is increased so that the detection portion 43a of the full detection lever 43 is placed at the highest position by its own weight. When it comes into contact with the payment slip S, the detection plate 43b of the full detection lever 43 moves toward the top plate 31d according to the storage height, and the end of the detection plate 43b is the optical axis of the full detection sensor 46. When a predetermined time elapses, the control unit recognizes that the medium storage case 26a is full, transmits a full detection notification to the main control unit of the automatic teller machine 1, and receives the main notification. The control unit stops the movement of the automatic teller machine 1.

  As described above, the storing operation of the payment slip S including the non-standard payment slip Sg by the medium storage structure of the present embodiment is performed.

  In the above description, the structure and storage operation of the shallow medium storage 26a has been described as an example, but the same applies to the case of the deep medium storage 26b.

  In the case of this deep medium storage 26b, the tip of the tongue piece 38a does not slide on the bottom plate 31e, but the standardized payment slip S and the non-standard payment slip Sg are sequentially accumulated on the bottom plate 31e. Then, when the upper surface of the uppermost payment slip S approaches the detection portion 43a of the full detection lever 43, the tip of the tongue piece 38a slides on the uppermost payment slip S, and the non-standard Even if the payment slip Sg is discharged from the medium carry-in port 33, as described above, the distance L2 between the front guide plate 31a and the rear guide plate 31b of the present embodiment is the longest nonstandard payment. Since the length of the letter Sg is a distance obtained by adding a predetermined margin, the center part of the non-standard payment letter Sg dropped on the uppermost payment letter S has a convex curve on the top plate 31d side. The top of the curved payment slip Sg is It is possible to prevent erroneous detection of the full state detecting portion 43a by pushing up.

  As described above, in this embodiment, it is possible to store the non-standard payment slip Sg by the front guide plate 31a and the guard surface of the guard part 41 between the feed roller 36 and the bottom plate 31e on the front guide plate 31a side. Even if a non-standard payment slip Sg is carried in, the payment slip Sg can be stored directly on the bottom plate 31e in a flat state, and automatic deposit due to a false detection of the full state. It is possible to prevent the stoppage of the payment machine and improve the movable efficiency of the automatic teller machine that enables the payment transaction using the payment slip S.

  In order to allow storage of non-standard payment slips Sg, it is conceivable to expand the storage space 34 by retracting the back guide plate 31b, but in this way, the standard released into the storage space 34 is considered. When the front end of the pay-in slip S collides with the rear guide plate 31b, it may not be possible to hit the rear end with the front end of the tongue piece 38a.

  As described above, in this embodiment, the front guide plate, the rear guide plate, the pair of side plates, the top plate, and the bottom plate form a housing space, and the medium provided on the front guide plate. The feed roller disposed at the carry-in port, the pressure roller disposed opposite to the top plate side of the feed roller, and the rotation shaft of the feed roller disposed in the axial direction orthogonal to the loading direction of the payment slip, And a stacking mechanism having a tongue roller provided with a plurality of tongue pieces, and an outer periphery of the feed roller on the back guide plate side in a medium storage structure for storing the pay-outs directly stacked on the bottom plate in the thickness direction. The surface protrudes from the front guide plate into the storage space, and has a guard surface disposed on the storage space side from the outer peripheral surface of the protrusion on both sides in the axial direction of the feed roller of the protrusion protruding into the storage space. Guard part Therefore, a recess that allows storage of non-standard payment slips Sg exceeding the upper limit of the standard tolerance can be formed between the feed roller and the bottom plate by the front guide plate and the guard surface of the guard part. Even if an outside payment slip Sg is carried in, it becomes possible to store the payment slip Sg directly on the bottom plate in a flat state, preventing the automatic teller machine from being stopped due to a false detection of the full state, The movable efficiency of the automatic teller machine which enabled the payment transaction by the payment document S can be improved.

  In addition, the medium processing unit including the medium storage having the medium storage structure according to the present embodiment can flatten the payment slip S including the non-standard payment slip Sg in the medium storage without using a special lifting device. The medium processing unit can be miniaturized.
