JP 2004-206362 A JP 2001-48362 A

  Here, the medium insertion portion into which sheet-like media such as checks are inserted in a bundle is wide, but a separation mechanism is provided for separating the sheet-like media fed from here by the feeding roller one by one. The medium delivery passage formed is narrow. The passage width between the medium insertion portion and the medium delivery passage is gradually reduced in the feed direction in order to guide the check fed by the feeding roller. There is no problem when the sheet-like medium of less than a predetermined number is overlapped and sent to the medium delivery passage. However, when a sheet-like medium of a number that is thicker than the passage width of the medium delivery passage is sent out as a bundle, In addition, there is a possibility that the sheet-like medium is clogged in the wedge portion in the passage portion on the entrance side of the medium delivery passage, and the delivery is impossible.

  An object of the present invention is to propose a medium feeding device capable of feeding a sheet-like medium inserted into a medium insertion portion in a bundled state through a narrow medium feeding path without causing the sheet-like medium to be fed out. is there.

  Another object of the present invention is to propose a medium processing apparatus provided with a medium feeding device capable of feeding a sheet-like medium inserted in a bundled state without falling into a state where it cannot be fed out.

In order to solve the above-described problem, the medium delivery device of the present invention provides:
A medium insertion part;
A medium delivery passage narrower than the passage width of the medium insertion portion;
A feeding roller for feeding the sheet-like medium inserted into the medium insertion portion in a state of being overlapped in the passage width direction to the medium feeding path;
A pressing member for pressing the sheet-like medium inserted into the medium insertion portion against the feeding roller;
A separation mechanism for separating the sheet-like medium fed from the medium insertion portion to the medium feeding path and feeding it from the medium feeding path;
The medium delivery path is characterized in that a medium receiving port connected to the medium insertion portion is provided with a minimum path width portion in the medium delivery path.

  In the medium delivery device of the present invention, the smallest passage width portion having the smallest passage width is formed at the portion of the medium receiving port which is the most upstream position of the medium delivery passage. The number of sheet-like media sent out in a state of being overlapped from the medium insertion portion is limited by the minimum passage width portion, and only the number of sheet-like media that can pass through the minimum passage width portion are sent out simultaneously to the medium delivery passage. Since the passage width of the downstream portion of the medium delivery passage is wider than the minimum passage width portion, the sheet-like medium does not get jammed in the inside of the medium delivery passage and cannot be delivered.

  Here, the passage width of the medium delivery passage may be the same in a portion other than the minimum passage width portion. Instead, the width of the passage portion from the portion where the minimum passage width portion is formed in the medium delivery passage to the medium delivery port of the medium delivery passage is directed from the minimum passage width portion toward the medium delivery port. You may make it spread gradually.

  Next, the medium guide surface that defines one of the medium delivery passages in the passage width direction is continuous with the insertion portion side first guide surface that defines one of the medium insertion portions in the passage width direction. A passage-side second defined by a flat passage-side first guide surface and facing the other medium guide surface in the passage width direction of the medium delivery passage with respect to the passage-side first guide surface at a predetermined interval. When defined by the guide surface, the edge portion of the passage side second guide surface on the medium insertion portion side, the insertion portion side first guide surface and the passage side first guide surface facing each other. The medium receiving port is defined by the boundary portion. In this case, the feeding roller is disposed on the insertion portion side first guide surface side, and the sheet-like medium fed by the feeding roller is fed into the medium feeding path along the insertion portion side first guide surface. It is.

  In this case, at least a part of the edge end portion projects toward the passage-side first guide surface at the edge portion of the passage-side second guide surface that defines one of the medium receiving ports. The projected portion is formed, and the minimum passage width portion can be formed by the projection.

  It is desirable that the protrusions be formed at portions other than both end portions of the edge end portion of the passage-side second guide surface. In this way, it can be avoided that the sheet-like medium fed out in a state in which the end portion is bent hits the protrusion and falls into a state where the feeding is impossible.

  In order to prevent the sheet-like medium having the bent end from being clogged at the medium receiving port of the medium delivery path, at least one end of the edge of the path-side second guide surface is provided. A taper-shaped guide surface that gradually approaches the passage-side first guide surface in the feeding direction of the sheet-like medium is formed on the portion, and the end of the sheet-like medium is guided in the feeding direction. Is desirable.

  The medium insertion portion is bent from an end of the insertion side second guide surface and the insertion portion side second guide surface facing the insertion portion side first guide surface in parallel at a predetermined interval. An orthogonal guide surface portion extending toward the section-side first guide surface, and a tip edge portion of the orthogonal guide surface portion is connected to the edge portion of the passage-side second guide surface. Can do.

  Next, a medium processing apparatus according to the present invention includes a medium feeding device having the above-described configuration, a conveyance path for conveying a sheet-like medium fed by the medium feeding apparatus, and a sheet-like medium conveyed along the conveyance path. And a processing unit that performs at least one of reading processing of the carried information and printing processing on the sheet-like medium.

  In the medium delivery device of the present invention, the smallest passage width portion having the narrowest passage width is formed in the medium receiving port portion of the narrow-width medium delivery passage through which the sheet-like medium is delivered from the medium insertion portion. This minimum passage width portion limits the number of sheet-like media fed into the medium delivery passage. Since the passage width of the medium delivery passage is wider than the minimum passage width portion, the number of sheet-like media limited by the minimum passage width portion is not clogged in the wedge state in the medium delivery passage. Therefore, it is possible to prevent the sheet-like medium from being clogged and being fed out when being fed from the medium insertion portion to the medium delivery path.

(Check delivery device)
FIG. 4 is a schematic configuration diagram showing a check delivery device including the check insertion portion 9, the check delivery path 17, and the check delivery mechanism 13.

  First, the structure of the check insertion portion 9 and the check delivery passage 17 will be described with reference to FIGS. The check insertion portion 9 is basically defined by a pair of left and right insertion portion side first guide surfaces 14 a, an insertion portion side second guide surface 15 a, and a bottom surface 16. The insertion portion side first guide surface 14a is a straight flat vertical surface. The insertion portion side second guide surface 15a is arranged in parallel to the insertion portion side first guide surface 14a at a constant interval, and from this front end edge, it is substantially directed toward the insertion portion side first guide surface 14a. An orthogonal guide surface portion 15b bent at an angle of 90 degrees extends, and a passage-side second guide surface 15c extends from the end of the orthogonal guide surface portion 15b in the check feeding direction. The end of the insertion portion side first guide surface 14a in the feed-out direction extends straight as it is to form a passage side first guide surface 14b.

  A check delivery passage 17 having a narrow passage width is defined by the passage-side first guide surface 14b and the passage-side second guide surface 15c facing the passage-side first guide surface 14b. The upstream end in the feed direction of the check delivery passage 17 is the edge portion 15d of the passage-side second guide surface 15c, the insertion portion-side first guide surface 14a and the passage-side first guide surface 14b facing each other. A check receiving port 17a defined by the boundary portion of Further, the downstream end of the check delivery path 17 in the feeding direction is a check delivery port 17 b connected to the check conveyance path 5.

  Here, the passage width of the check delivery passage 17 is set to a constant width as a whole, but the smallest passage width portion 17c having the narrowest passage width is formed only in the portion of the check receiving port 17a. The minimum passage width portion 17c is formed such that the rear edge portion 15d of the passage-side second guide surface 15c defining one of the check receiving ports 17a is partially connected to the other passage-side first guide surface 14b. It is formed by a plurality of protrusions 70 protruding in a rectangular shape. For example, three protrusions 70 are formed.

  If it demonstrates with reference to FIG.4 (b) and (c), the three protrusions 70 will be formed in the edge part 15d of the channel | path side 2nd guide surface 15c up and down by predetermined spacing. The protrusions of these protrusions 70 are the same, and the minimum passage width portion 17c is formed at three locations between these front end surfaces and the passage-side first guide surface 14b facing the tip surfaces. The portion between these minimum passage width portions 17c is the same as the other passage widths as shown in FIG. 4 (d). As shown in FIG. 4E, the lower end portion of the edge portion 15d of the passage-side second guide surface 15c approaches a taper shape from the orthogonal guide surface portion 15b toward the passage-side first guide surface 14b. A tapered guide surface 15e is formed.

  For example, the thickness of the check 4 is about 0.1 to 0.14 mm. The passage width of the check delivery passage 17 is set to about 1.6 mm. In this case, the width of the minimum passage width portion 17c can be set to about 1 mm. This width dimension is a property that should be appropriately set according to the shape of the protrusions 70a to 70c, the material of the check 4, and the like.

  In this example, the overall width of the check delivery passage 17 is constant, but the passage width may be gradually increased from the check receiving port 17a toward the check delivery port 17b.

  Next, the check feeding mechanism 13 will be described mainly with reference to FIG. The check feeding mechanism 13 includes a feeding roller 71 for feeding the check 4 and a pressing member 72 for pressing the check 4 against the feeding roller 71 side. Further, a separation mechanism 73 is provided for sending the check 4 sent to the check delivery path 17 by the feed roller 71 one by one to the check conveyance path 5.

  The feeding roller 71 is disposed on the insertion portion side first guide surface 14a, and its outer peripheral surface slightly protrudes from the insertion portion side first guide surface 14a to the check insertion portion 9. An opening 15 f (see FIG. 1) is formed in the other insertion portion side second guide surface 15 a facing the feed roller 71. The pressing member 72 can be moved back and forth to the check insertion portion 9 through the opening 15f.

  The pressing member 72 has a rear end portion 72a supported so as to be rotatable about a support shaft 72b, and a check pressing surface 72c is formed on the front end side thereof. When the pressing member 72 is pivoted from the standby position shown in FIG. 4 toward the check insertion portion 9 around the support shaft 72b, the pressing member 72 has its check pressing surface 72c advanced into the check insertion portion 9, It can turn to the pressing position pressed against the feeding roller 71. Therefore, when the check 4 is put in the check insertion portion 9, a state in which the check 4 is pressed against the feeding roller 71 by the pressing member 72 is formed. When the feeding roller 71 is rotated in this state, the check 4 in contact with the feeding roller 71 is sent out to the check feeding path 17.

  The standby position of the pressing member 72 is detected by, for example, a sensor (not shown) such as a mechanical switch attached to the apparatus main body. The operation of pressing the pressing member 72 against the check 4 inserted into the check insertion unit 9 is performed by detecting the check 4 by a transmissive optical sensor (not shown) attached to the check insertion unit 9, for example. If allowed. When the check 4 is detected, the pressing member 72 is advanced from the standby position according to a command from the computer system 103 (see FIG. 6) which is a host device of the check processing device 1 or based on a manual operation input command. A state in which the check 4 is turned toward the roller 71 and the check 4 is pressed against the feeding roller 71 is formed.

  Next, the separation mechanism 73 disposed in the check delivery path 17 is a retard roller type separation mechanism including a separation roller 74 and a retard roller 75. The separation roller 74 and the retard roller 75 are arranged in the middle of the check delivery path 17. A separation roller 74 is disposed on the side of the first guide surface 14b defining the check delivery passage 17, and retarded on the second guide surface 15c side of the other passage defining the check delivery passage 17. A roller 75 is disposed. A constant rotational load acts on the retard roller 75 by a torque limiter 76 disposed adjacent thereto.

(Check separation feeding operation)
With reference to FIG. 5, the check separating and feeding operation of the check feeding device will be described. First, the feeding roller 71 and the separation roller 74 are rotated in the feeding direction by a driving source (not shown), and the pressing member 72 is pushed out from the standby position toward the pressing position. As a result, as shown in FIG. 5A, the checks 4 inserted into the check insertion portion 9 in a bundle are pressed against the feeding roller 71 by the pressing member 72, and from the checks 4 that are in contact with the feeding roller 71. In order, the sheet is sent out along the insertion portion side first guide surface 14a.

  The check 4 sent out along the insertion portion side first guide surface 14 a is sent into the check delivery passage 17 from the check receiving port 17 a of the check delivery passage 17. A protrusion 70 is formed in the check receiving port 17a, and a minimum passage width portion 17c having the narrowest passage width is formed. Therefore, as shown in FIG. 5B, when a plurality of checks 4 are sent out in a bundle, the number of checks sent out simultaneously by the minimum passage width portion 17c is limited. As a result, the stack thickness of the fed check becomes thinner than the passage width of the check delivery passage 17. Therefore, the check 4 sent from the check receiving port 17a does not get stuck in the wedge state in the check delivery passage 17 and cannot be sent out.

  The check 4 sent to the check delivery passage 17 is separated when passing through the nip portion of the separation roller 74 and the retard roller 75 and is sent one by one toward the check delivery port 17b as shown in FIG. 5 (c). From here, it is sent out to the check conveyance path 5.

  This example is an example in which the present invention is used as a check feeding device in a check processing device. The medium feeding apparatus of the present invention can be similarly applied to an apparatus for processing a sheet-like medium other than a check processing apparatus such as a printer, a scanner, or a magnetic reading apparatus.

(Control system for check processing equipment)
FIG. 6 is a schematic block diagram showing a control system of the check processing device 1. The control system of the check processing apparatus 1 includes a ROM and a RAM, and includes a control unit 101 that is configured around a CPU. The control unit 101 is connected to the upper computer system 103 via the communication cable 102. The computer system 103 includes input / output devices such as a display 103a, an operation unit 103b such as a keyboard and a mouse, and a check reading operation start command is input to the control unit 101 from the computer system 103 side.

  When the control unit 101 receives a reading operation start command, the controller 101 drives the driving motor 104 which is a driving source of the conveying motor 21, the feeding roller 71, the pressing member 72, and the separation roller 74 to feed the checks 4 one by one to the check conveying path 5. And the sent check 4 is transported along the check transport path 5. The control unit 101 receives the surface image information, the back surface image information, and the magnetic ink character information of the check 4 read by the front surface side contact image scanner 52, the back surface side contact image scanner 53, and the magnetic head 54. These pieces of information are supplied to the computer system 103, where image processing, character recognition processing, and the like are performed, whether or not reading has been performed normally is determined, and the determination result is supplied to the control unit 101. The control unit 101 controls driving of the printing mechanism 56 and the switching plate 66 based on the determination result.

  The conveyance control of the check 4 by the control unit 101 is performed by detecting signals from the sheet length detector 61, the double feed detector 62, the jam detector 63, the print detector 64, and the discharge detector 65 arranged in the check conveyance path 5. Based on Note that an operation unit 105 including an operation switch such as a power switch formed on the main body case 2 is connected to the control unit 101.

(Check processing operation)
FIG. 7 is a schematic flowchart showing the processing operation of the check processing device 1. First, when the operator inputs a reading start command from the operation unit 103b of the host computer system 103, when the insertion of the check 4 is detected by the sensor, the feeding roller 71 rotates and the pressing member 72 moves to feed the check 4 out. Press against the roller 71. As a result, the check 4 is sent out by the feeding roller 71 (see FIG. 5A). Further, the transport motor 21 is driven, and the transport rollers 31 to 37 are rotationally driven. The checks 4 fed out to the check delivery path 17 are separated one by one by the separation mechanism 73 arranged in the check delivery path 17 and sent out to the check conveyance path 5 (steps ST1, ST2, FIG. 5B). ) And (c)).

  The sent check 4 is conveyed along the check conveyance path 5 while being sequentially delivered to the conveyance rollers 31 to 36 (step ST3). The front and back images and magnetic ink characters of the check 4 being conveyed are read by the front-side contact image scanner 52, the back-side contact image scanner 53, and the magnetic head 54, respectively (step ST4).

  The read information is transmitted to the upper computer system 103 via the communication cable 102 (step ST5). The front side image, the back side image, and the magnetic ink character information read on the computer system 103 side are processed to determine whether the reading has been performed normally. When the check 4 is conveyed upside down, the magnetic ink character cannot be recognized, and it is determined that the reading is defective. When the check 4 is conveyed in the reverse state, the magnetic ink character information cannot be obtained, so that it is determined that reading is impossible. Further, even when a part of the magnetic ink character cannot be read due to the check 4 being broken, torn, or skewed during conveyance, it is determined that the reading is defective. Furthermore, it is determined from the image information on the front and back sides that the check 4 is defective even when the check 4 is broken, torn, or skewed at the time of conveyance, or when predetermined information such as money amount information cannot be recognized.

  If it is determined that the reading is normal, the printing mechanism 56 is moved to the printing position (steps ST8 and ST10). The check 4 is conveyed while printing such as “electronic payment completed” is performed by the printing mechanism 56, and is discharged to the first check discharge unit 11 side by the switching plate 66 (step ST10). After the trailing edge of the check 4 is detected by the discharge detector 65, the transport operation is stopped (steps ST11 and ST12).

  On the other hand, when a determination result such as reading failure or reading failure is obtained (step ST8), a switching operation of the switching plate 66 is performed (step ST14). The printing mechanism 56 is held at the standby position, and printing on the check 4 is not performed. The check 4 is distributed to the second check discharge unit 12 by the switching plate 66 and discharged there (step ST14). After the trailing edge of the check 4 is detected by the discharge detector 65, the conveying operation is stopped (steps ST11 and ST12).

  If a double feed state is detected by the double feed detector 62, an interrupt process is performed, the conveyance is immediately stopped, and an abnormality is detected via a warning lamp or the like disposed in the operation unit 105, for example. A warning is given to the effect that conveyance has occurred, and it is awaited that the check is removed from the check conveyance path 5 and returned to the initial state. Similarly, similar interrupt processing occurs when the jam detector 63 detects that the check is jammed in the check conveyance path 5.
