Description

[Technical field]

[0001] The present embodiment relates to a printer. [Background technology]

[0002] Conventionally, terminal devices such as ATMs (Automatic Teller Machines) and kiosks installed in a corner of a store to accept bank account transaction procedures, etc., have built-in printers used to print bank statements (paper documents that record details such as deposit account transaction records).

[0003] In such printers, if the printed paper is not removed from the outlet for a certain period of time, the printer will pull the paper back from the outlet to prevent inconvenience caused by unauthorized persons getting their hands on the statement. The pulled back paper is discharged from the back of the printer and stored inside the kiosk terminal. This stored paper is periodically removed, but since it is stored in a place that is difficult to access, the removal process is cumbersome.

[0004] Some printers as described above have a structure in which the unit is divided into two halves, upper and lower, to open the inside (for example, Patent Document 1). One example of such a structure is an upper module stacked on a lower module, and the front side is lifted using the back side as a fulcrum, exposing the inside of the printer. Printers with such a structure are equipped with a mechanism for prohibiting (locking) opening and closing operations in preparation for operation.

[0005] When performing maintenance such as clearing a paper jam, the above lock is released to open and close the inside of the printer, but some printers have a section for this operation that is located at the back when the operator is standing in front of the printer. Such printers require space on the side of the printer where the operator can insert their hands.

[0006] However, terminal devices such as ATMs and kiosks are designed to be narrow in width to reduce the installation area, and as a result, there is often little space inside the terminal, making it difficult to obtain enough space for an operator to insert their hand into the side of the built-in printer. Summary of the Invention [Problem to be solved by the invention]

[0007] The problem that the present invention is to solve is to facilitate the recovery of paper that has been discharged and then pulled back. [Means for solving the problem]

[0008] The printer of the embodiment comprises a lower module having a paper feed unit that supplies paper and a printing unit that prints on paper supplied by the paper feed unit; an upper module located above the lower module and rotatably supported at its rear side by the lower module, which moves towards and away from the lower module as it rotates; a loading unit provided on the upper module for holding paper after printing by the printing unit; a discharge unit provided on the upper module for discharging paper held by the loading unit out of the upper module while clamping the rear end of the paper in the transport direction and pulling the paper back into the upper module after a predetermined time has elapsed; and a storage unit having a support member rotatably supported at its rear side at the bottom of the upper module and which moves towards and away from the upper module as it rotates, and between the support member and the upper module for storing the paper pulled back by the discharge unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] An embodiment will be described with reference to the drawings. Fig. 1 is a diagram showing a schematic configuration of a kiosk terminal 2 with a built-in printer 1 according to an embodiment. In Fig. 1, the operator of the kiosk terminal 2 stands on the left side of the figure. In other words, the left side of the figure is the front of the kiosk terminal 2, and the kiosk terminal 2 shown in Fig. 1 is viewed from the right side.

[0011] In this embodiment, an example is described in which the printer 1 is built into a kiosk terminal 2; however, this is not limited to this example, and the printer 1 may be built into, for example, an ATM or other device.

[0012] The kiosk terminal 2 is equipped with an operation display unit 4 on top of a vertically long box-shaped main body 3. The operation display unit 4 accepts operations according to the displayed content, and is, for example, a touch panel overlaid on the surface of a display device such as a liquid crystal panel. The main body 3 has a built-in printer 1, a card reader / writer (not shown), and the like.

[0013] The left side in the figure is where the operator of the kiosk terminal 2 stands, the operation display unit 4 displays information facing the operator's position, and the printer 1 issues printed materials facing the operator's position. Such a kiosk terminal 2 is not necessarily open to the outside except for the operator's position, and is therefore configured so that not only the operator can operate it, but also maintenance can be performed from the front side (i.e., the left side in the figure).

[0014] The structure of the printer 1 will be described below with reference to Figures 2 to 11. First, Figures 2 and 3 are diagrams showing an example of the structure of the printer 1, with Figure 2 showing the printer 1 in an operating state and Figure 3 showing the printer 1 in an open state. Figure 4 is a perspective view corresponding to Figure 3, showing the printer 1 in the open state.

[0015] 2 and 3, the left side of the figures is the front side (nearby side) of printer 1, so the left-right direction in the figures is the depth direction (front-rear direction) of printer 1, and the depth direction in the figures (direction perpendicular to the paper surface) is the width direction (left-right direction) of printer 1. Also, the up-down direction in the figures is the height direction of printer 1. Also, FIG. 4 is a view of printer 1 as seen obliquely from the front side.

[0016] The printer 1 includes a lower module 10, an upper module 20, a storage section 30, a first locking section 40, a second locking section 50 (see FIG. 3), and an interlocking section 60.

[0017] The lower module 10 is provided with a paper feed section 11, a printing section 12, and a transport section 13. The upper module 20 is provided with a stacking section 21 and a discharge section 22.

[0018] The printer 1 is provided with a shaft 19 that runs along the width direction (left-right direction) of the printer 1 at the rear side of the upper module 20 and the lower module 10. The shaft 19 rotatably attaches the upper module 20 to the lower module 10. As a result, the upper module 20 is positioned above the lower module 10, the rear side of which is rotatably supported by the lower module 10, and moves toward and away from the lower module 10 as it rotates. A biasing member (not shown) that biases the upper module 20 in a direction to lift it is provided near the shaft 19. This biasing member is, for example, a torsion spring or the like that is provided around the shaft 19.

[0019] The paper feed unit 11 has two paper feed paths 111, 112, and supplies paper taken in from each of the paper feed paths 111, 112 to the printing unit 12. The paper feed unit 11 has two paper feed paths 111, 112. For example, the paper feed unit 11 first supplies paper to the printing unit 12 via the first paper feed path 111, and when the paper runs out, it backfeeds the paper in the paper feed path 111 to remove it from the printing unit 12, and then resumes supplying paper via the second paper feed path 112. The paper is, for example, fanfold paper. The folded portion of the fanfold paper before being pulled out is stored in the lower part of the vertically long box-shaped main body 3 shown in FIG. 1.

[0020] The printing unit 12 includes a print head and a platen, and prints on paper sandwiched between them. A cutter is provided downstream of the printing unit 12 to cut the paper to a specified length after printing. The transport unit 13 has a roughly U-shaped transport path from the lower module 10 to the upper module 20, and sends the printed and cut paper to the stacking unit 21.

[0021] The stacking unit 21 is provided in the upper module 20 and holds paper after printing by the printing unit 12. More specifically, the stacking unit 21 stacks and aligns a plurality of sheets of paper that have been printed and cut to a predetermined length into a paper stack.

[0022] The discharge section 22 is provided in the upper module 20, and discharges the stack of sheets aligned and held by the stacking section 21 out of the upper module 20 while clamping the rear end of the stack in the transport direction. In addition, the discharge section 22 pulls the stack of sheets back into the upper module 20 after a predetermined time has passed.

[0023] Next, the storage section 30 will be described. First, Fig. 5 is a diagram showing an example of the appearance of the members that make up the storage section 30. The storage section 30 is provided with a tray 31, which is a plate-shaped member, as a support member that supports paper. The rear end 32 of the tray 31 is rotatably supported by the lower part of the upper module 20 as shown in Fig. 3, and moves toward and away from the upper module 20 as it rotates. When the upper module 20 is in a position adjacent to the lower module 10 and the printer 1 is in an operating state, the storage section 30 is fixed in a position adjacent to the upper module 20 by the second lock section 50.

[0024] The tray 31 is loaded with the paper sheets pulled back by the discharge section 22. The storage section 30 stores the paper sheets pulled back by the discharge section 22 between the tray 31 and the upper module 20. Fig. 6 is a perspective view showing the state in which the paper sheets S are placed on the tray 31. A hole 33 is formed in the center of the width of the tray 31 to pinch the paper sheets S in the thickness direction and make it easier to pick up the paper sheets S.

[0025] Next, the first locking part 40 will be described with reference to Figures 2, 3, and 7. The first locking part 40 fixes the upper module 20 in a position adjacent to the lower module 10 so that it cannot rotate. When the fixation (lock) by the first locking part 40 is released, the upper module 20 moves in a direction away from the lower module 10 due to the biasing force of a biasing member provided near the shaft 19.

[0026] Furthermore, the above-mentioned biasing member only needs to have a minimum biasing force sufficient to prevent unintentional re-locking of the first locking portion 40 due to the upper module 20 descending under its own weight, and does not need to have a biasing force sufficient to bounce the upper module 20 up to the state shown in Figure 3, for example, and it is preferable that the upper module 20 is lifted to the point where the operator recognizes that the lock has been released.

[0027] A specific example of the configuration of the first locking portion 40 will be described. The first locking portion 40 of this embodiment includes a stud 41, which is an example of a first fastener, a first lever 42, a shaft 43, and a biasing member 44. The biasing member 44 is, for example, a tension spring. The stud 41 is provided in the lower module 10. The shaft 43 and the first lever 42 are provided in the upper module 20.

[0028] The first lever 42 is rotatably attached to the side plate 25 of the upper module 20 by a shaft 43 that extends along the width direction (left-right direction) of the printer 1. As the first lever 42 rotates, it can move between a holding position (see FIG. 2) where the stud 41 is held, and a release position (see FIG. 7) where the hold of the stud 41 is released. FIG. 7 is a diagram showing the first lever 42 in the release position.

[0029] The biasing member 44 biases the first lever 42 in a direction from the release position toward the retaining position (counterclockwise direction in the figure). When the external force that positions the first lever 42 at the release position against the bias of the biasing member 44 is removed, the first lever 42 automatically returns to the retaining position.

[0030] The first lever 42 has a groove 421 and a pressed portion 422. The groove 421 has a width that allows the stud 41 to enter and exit, and catches and holds the stud 41 when the upper module 20 is in a position close to the lower module 10.

[0031] The pressed portion 422 is a portion that receives a pressing force from a link lever 61 (described later), and is located on the opposite side of the shaft 43 from the groove 421. When the pressed portion 422 is pressed, the first lever 42 rotates in a direction in which the stud 41 comes out of the groove 421.

[0032] The first lever 42 has a guide slope 423 at its tip that guides the stud 41 into the groove 421. The guide slope 423 is provided to slide against the stud 41 and encourage the rotation of the first lever 42 when the upper module 20 descends from a position away from the lower module 10 to a position close to the lower module 10.

[0033] Next, the interlocking unit 60 will be described with reference to Figures 7 and 8. Figure 8 is a diagram showing an example of the structure of the printer, showing a state in which the link lever 61 has been removed from Figure 2. The interlocking unit 60 has the link lever 61, studs 66 and 67, and a biasing member 69 (see Figure 8). The biasing member 69 is, for example, a tension spring.

[0034] The link lever 61 is provided on the upper module 20 with its longitudinal direction facing the depth direction of the upper module 20, and has a handle 62 protruding on the front side of the upper module 20, and a pressing part 63 on the rear side. The pressing part 63 is provided at a position facing the pressed part 422 of the first lever 42.

[0035] Further, two elongated holes 64, 65 are formed in the link lever 61. The elongated holes 64, 65 are provided apart from each other in the longitudinal direction of the link lever 61. The longitudinal direction of the elongated holes 64, 65 is aligned with the longitudinal direction of the link lever 61.

[0036] The studs 66, 67 are attached to the upper module 20 at a distance from each other in the front-rear direction, and are slidably fitted into the elongated holes 64, 65, respectively. This allows the link lever 61 to slide in the front-rear direction of the upper module 20.

[0037] Furthermore, a notch 68 is formed between the long holes 64 and 65 of the link lever 61. One end of a biasing member 69 is attached to this notch 68. The other end of the biasing member 69 is attached to the upper module 20. The biasing member 69 connects the notch 68 formed in the link lever 61 and the upper module 20. As a result, the link lever 61 is biased toward the front side of the upper module 20.

[0038] In this way, the link lever 61 can move back and forth between the front side and the rear side of the printer 1, and acts on the first locking part 40 and the second locking part 50 when moving to the rear side as indicated by the arrow in Fig. 7. In other words, the link lever 61 moves the first lever 42 to the release position and also moves the second lever 54 (described later) to the release position.

[0039] More specifically, regarding the action of the link lever 61 on the first lever 42, when the handle 62 of the link lever 61 is pushed in while the upper module 20 is in a position adjacent to the lower module 10, the pressing portion 63 moving toward the back side of the upper module 20 presses the pressed portion 422. This causes the first lever 42 to rotate, the stud 41 comes out of the groove 421, the retention of the stud 41 is released, and the upper module 20 is lifted by the bias of the biasing member near the shaft 19.

[0040] Next, the second locking part 50 will be described with reference to Fig. 3 and Fig. 8 to Fig. 11. As shown in Fig. 3 and Fig. 8, the second locking part 50 is composed of a slide pin 51, a guide part 52, a notch part 53, a second lever 54, a shaft 55, and a biasing member 58 (see Fig. 9). The biasing member 58 is, for example, a tension spring. Fig. 9 is an enlarged view of the second locking part 50.

[0041] The lower module 10 includes a support portion 15 that supports the lower surface of the tray 31 that is separated from the upper module 20. A supported portion 34 that faces the support portion 15 is provided on the lower surface of the tray 31 so as to protrude therefrom.

[0042] The guide portion 52 guides the slide pin 51 to be movable within a predetermined range along the depth direction of the tray 31, and is, for example, a long hole formed in the side portion of the tray 31 with its longitudinal direction facing the depth direction of the tray 31. The slide pin 51 is an example of a second fastener, and by sliding within the guide portion 52, it is capable of reciprocating movement between the front side and the back side in the depth direction of the tray 31.

[0043] The biasing member 58 biases the slide pin 51 toward one end of its movable range, that is, biases the slide pin 51 toward one side of the guide portion 52. In this embodiment, the biasing member 58 biases the slide pin 51 toward the front side of the printer 1 (the left side in the figure).

[0044] 10 is an enlarged view of the cutout portion 53. The cutout portion 53 is provided in the lower end portion of the side plate 25 of the upper module 20. The cutout portion 53 is an example of a holding portion, and holds the slide pin 51.

[0045] The cutout portion 53 has four sections on the edge closer to the front side of the printer 1: a slope portion 531, a bent portion 532, a slope portion 533, and a terminal end portion 534. The slope portion 531 faces diagonally downward behind the printer 1. The slope portion 533 faces diagonally upward behind the printer 1. The bent portion 532 smoothly connects the slope portion 531 and the slope portion 533.

[0046] The inclined surface 531 moves the slide pin 51 of the tray 31 supported by the support portion 15 against the bias of the biasing member 58 as the upper module 20 approaches the lower module 10 from the open state of the printer 1.

[0047] The slide pin 51 moves while sliding on the inclined surface portion 531, and after passing the bent portion 532, it moves while sliding on the inclined surface portion 533 due to the bias of the biasing member 58, and reaches the terminal portion 534. With the slide pin 51 in the terminal portion 534, the second locking portion 50 is locked, and the storage portion 30 is fixed at a position close to the upper module 20.

[0048] The inclined surface portion 533 converts the force received from the slide pin 51 moving according to the bias of the biasing member 58 into a force that moves the tray 31 closer to the upper module 20. As a result, the tray 31 is lifted, the supported portion 34 on the lower surface of the tray 31 is separated from the support portion 15, and a gap is created between the supported portion 34 and the support portion 15. This also results in a state in which the storage portion 30 and the lower module 10 do not interfere with each other, so that the upper module 20 can be pushed down a little further. After a gap is created between the supported portion 34 and the support portion 15, the upper module 20 is pushed down slightly, and is locked by the first lock portion 40. In this way, the inclined surface portion 533 is formed in a position and shape that guides the slide pin 51 before the upper module 20 is fixed by the first lock portion 40.

[0049] Next, the second lever 54 will be described. As shown in Fig. 8, the second lever 54 is rotatably attached to the side plate 25 of the upper module 20 by a shaft 55 along the width direction (left-right direction) of the printer 1. With this rotation, the second lever 54 can move between a position where it does not interfere with the slide pin 51 and a release position where the hold of the slide pin 51 by the notch 53 is released. The second lever 54 rotates by the force transmitted from the interlocking part 60. Fig. 11 is a diagram explaining the relationship between the interlocking part 60 and the second locking part 50.

[0050] The link lever 61 of the interlocking unit 60 is positioned so as to overlap the second lever 54 of the second locking unit 50 on the outer side in the width direction of the printer 1. The second lever 54 has a protrusion 56 that is long in the up-down direction of the printer 1. The protrusion 56 protrudes toward the outer side in the width direction of the printer 1, that is, toward the link lever 61. The link lever 61 is formed with a recess 57 into which the protrusion 56 slidably fits. The link lever 61 and the second lever 54 intersect at the position where the protrusion 56 fits into the recess 57.

[0051] With this structure, when the link lever 61 moves in the depth direction of the printer 1, the recess 57 also moves in the depth direction, and the protrusion 56 fitted in the recess 57 also moves in the depth direction. At that time, the protrusion 56 slides relative to the recess 57. As a result, the second lever 54 receives a force in the depth direction and rotates around the shaft 55. Then, the second lever 54 interferes with the slide pin 51 and moves the slide pin 51 against the bias of the biasing member 58. At this time, the upper module 20 is released from the lock by the first locking part 40 and biased in the opening direction. Therefore, the slide pin 51 moves from the terminal part 534 through the slope part 533, over the bent part 532, and out of the notch part 53. As a result, the lock by the second locking part 50 is released, and the storage part 30 is opened.

[0052] In the printer 1 configured as described above, when an operator opens the inside of the printer 1 for maintenance or the like, he or she first holds the handle 62 of the link lever 61 and pushes the link lever 61 in the direction from the front of the printer 1 to the back.

[0053] When the link lever 61 is pushed in from the front of the printer 1 toward the back, the pressing portion 63 of the link lever 61 presses the pressed portion 422 of the first lever 42. This causes the first lever 42 to rotate clockwise in FIG. 2. This releases the stud 41 from the groove 421. The upper module 20 then rotates around the shaft 19 due to the bias of the biasing member, and is lifted up. This allows the operator to recognize that the lock by the first locking portion 40 has been released. The operator, having recognized that the lock by the first locking portion 40 has been released, lifts up the upper module 20. This causes the upper module 20 to rotate further around the shaft 19.

[0054] Furthermore, when the link lever 61 is pushed in from the front of the printer 1 toward the back, the recess 57 of the link lever 61 moves the protrusion 56 of the second lever 54 in conjunction with the above operation, causing the second lever 54 to rotate and release the lock provided by the second locking part 50. This opens the storage section 30.

[0055] Furthermore, when the operator opens the printer 1 in order to deal with a paper jam, for example, the operator has no need for the storage unit 30, so the operator manually pushes the tray 31 upward from the bottom to close the storage unit 30 and locks it in place with the second lock unit 50. After that, the operator deals with the paper jam or the like.

[0056] Next, a case where an operator who has completed maintenance or the like returns the upper module 20 to a position close to the lower module 10 will be described. First, the operator presses down the upper module 20 against the bias of the biasing member around the shaft 19. This causes the upper module 20 to lower while rotating around the shaft 19. This causes the guide slope 423 at the tip of the first lever 42 to slide on the stud 41, and as the first lever 42 slides, it rotates against the bias of the biasing member 44. When the guide slope 423 passes the stud 41, the stud 41 fits into the groove 421 and is held there. This causes the upper module 20 to reach the completely closed position, and the printer 1 becomes ready for operation.

[0057] If the storage section 30 is open when performing the above operation, when the upper module 20 rotates down around the axis 19, the slide pin 51 of the second locking section 50 enters the notch 53 and is locked.

[0058] Thus, according to the printer 1 of this embodiment, the first locking unit 40 and the second locking unit 50 provided on the rear side of the printer 1 can be operated by operating the link lever 61. Therefore, according to this embodiment, with a single action of pushing in the link lever 61, the upper module 20 can be released from the fixation of the lower module 10 to the upper module 20, making the upper module 20 rotatable in a direction that opens up the space between the upper module 20 and the lower module 10, and the storage unit 30 can be released from the fixation of the upper module 20 to the upper module 20, thereby opening the storage unit 30.

[0059] Furthermore, according to this embodiment, it is possible to open and close the upper module 20 and the lower module 10 vertically without inserting a hand from the side of the printer 1 to the back side.

[0060] Furthermore, according to this embodiment, a storage section 30 can be obtained that stores paper pulled back by the discharge section 22, and although the number of storage sections 30 has increased in the printer 1 compared to the conventional method, the number of operations required to open the printer 1 remains the same as before, so that the storage section 30 can be used without compromising operability.

[0061] Furthermore, in the past, it was necessary to collect paper that had fallen into the kiosk terminal 2 from the back side of the printer 1, but by storing paper pulled back by the discharge section 22 in the storage section 30, it is possible to collect paper from the front side of the printer 1, which is convenient.

[0062] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
