Description

  The present invention relates to a paper sheet discharge device that handles, for example, receipts, cards, and the like, and more particularly to a discharge unit that discharges paper sheets.

  2. Description of the Related Art Conventionally, for a receipt printer, a card handling device, and the like, a medium conveying device in which a pin clutch is adopted for a roller of a discharge unit has been proposed (see Patent Document 1). This medium conveying apparatus is configured such that an operator can pull out the medium with a small force after conveying the medium to the discharge unit by the pin clutch.

  More specifically, as shown in FIG. 11, the stopper pin 125 and this pin clutch are provided with a stopper pin 125 on the drive shaft 121 of the conveying roller 122 and are driven by a protrusion 26 a of the pulley 126 that engages with the stopper pin 125. Is transmitted to the drive shaft. The engagement portion between the stopper pin 125 and the protrusion 26a is provided with a backlash. When the power is transmitted when the medium is discharged, the play is moved in one direction, the stopper pin 125 comes into contact with the protrusion 26a, and the rotation is transmitted to the drive shaft 121 through the protrusion 26a. Thereafter, when the operator pulls the medium, the conveying roller 122 is rotated in the direction of the play, and the stopper pin 125 that has been in contact with the protrusion 126a of the pulley 126 is separated from the protrusion 126a and connected to the power system. The transport roller 121 can be rotated without rotating 126. As a result, the medium can be extracted with a light force.

  On the other hand, when issuing a medium such as a receipt on which more information is printed than before, there are methods of increasing the size of the receipt or reducing the characters. Here, when the receipt width is increased in order to increase the size of the receipt, there is a problem that the width of the receipt printer is increased and the apparatus is enlarged. In addition, there is a problem that it becomes difficult to read if the characters are made smaller. For this reason, a method of increasing the printable information by increasing the length of the receipt becomes the mainstream.

  However, the configuration of the pin clutch described above is limited to a length that can be extracted with a light force to a length corresponding to a rotation amount of less than 360 degrees obtained by removing the thickness of the pin or gear catching portion from one rotation of the transport roller. It is done. For this reason, in the case of a long receipt, if the length corresponding to the amount of rotation is extracted, the pin and the gear come into contact with each other, and it becomes impossible to rotate more lightly. Accordingly, there arises a problem that the force for extracting from the middle increases and it becomes difficult to extract. If the transport roller is made larger, the amount of rotation possible with the pin clutch can be removed completely even with a long receipt even with a light force. However, as the transport roller becomes larger, the entire apparatus becomes larger. The problem arises.

  Other methods include reducing the clamping force of the roller itself to slip the conveying roller and the receipt to reduce the extraction force, and increasing the receipt discharge amount to reduce the extraction amount.

  However, if the clamping force is weakened, there is a problem that the conveyance performance is lowered and the possibility of jamming occurs. In addition, if the receipt discharge amount is increased, the receipt will not be able to maintain its posture from the discharge port and will hang down, making it difficult to grasp, and the cash dispenser installed at financial institutions on top of the card. This causes a problem that the card is covered and hidden when it is ejected.

  An object of the present invention is to ensure ease of extracting a long receipt without causing the above-described problems.

  The present invention includes a conveyance roller shaft having a conveyance roller for conveying paper sheets, a rotation driving member that is rotatably arranged on the conveyance roller shaft and rotates by a rotation driving force from a rotation driving unit, and the conveyance roller And an interposition body that is rotatably arranged on a shaft and transmits the rotational force of the rotation driving member to the transport roller shaft, and the transport roller shaft has a shaft locking portion at a part of the rotation circumference. The rotation driving member has a drive locking part on a part of the rotation circumference, and the interposition body is provided on a part of the rotation circumference and contacts the shaft locking part. And a drive-side abutting portion that is provided on a part of the rotation circumference and abuts against the driving locking portion.

  It is possible to ensure the ease of extracting a long receipt.

FIG. 3 is a side view showing a schematic configuration of the card / detail slip mechanism 12.
The card / detail slip mechanism unit 12 is provided with a receipt printer 13 on the upper level and a card reader 14 on the lower level, and the receipt printer 13 and the card reader 14 are arranged vertically.

A card handling port 4 is provided on the front surface of the card reader 14.
A transport roller 22 and a driven roller 24 are provided at the lower front portion of the receipt printer 13, and a receipt handling port 3 is provided so as to protrude to the card reader 14 below the front surface. The receipt handling port 3 is disposed close to the upper portion of the card handling port 4.

  The receipt printer 13 is driven by the control of the control unit 10 shown in FIG. 2, and can change the length of a receipt to be issued according to the amount of information to be printed. That is, a cutter (not shown) is provided inside, and roll paper or the like is appropriately cut to print information and issue a receipt. At the time of issuance, the leading edge of the receipt is detected by a sensor (not shown) provided in the conveyance path so that the discharge amount (projecting length) from the receipt handling port 3 becomes a predetermined amount. Stops the transport when discharging. Accordingly, although the amount of receipt discharged is always the same, the length of the receipt remaining portion remaining inside the apparatus differs depending on the length of the receipt. The receipt discharge amount is preferably set to a length that does not completely hide the card located below in a state where the card discharged from the card reader 14 and the receipt discharged from the receipt printer 13 overlap.

  With this configuration, as shown by a one-dot chain line in FIG. 3, the card is discharged substantially horizontally from the card handling port 4, and the receipt is discharged from the receipt handling port 3 to the front, and the discharged receipt and card are used by the user. Can be pulled out with one hand.

  FIG. 4 is a perspective view showing a configuration of the receipt discharging unit 20 provided with the conveying roller 22 and the driven roller 24, FIG. 5 is a perspective view of a pulley 26 as a rotation driving member, and FIG. It is a perspective view of the rotary disk 29 as.

  In the receipt discharge unit 20, a driven shaft 23 in which a driven roller 24 is rotatably arranged and a drive shaft 21 as a conveying roller shaft to which the conveying roller 22 is fixed are arranged in this order in the vertical direction. The driven roller 24 and the conveying roller 22 are opposed to each other in the vertical direction, and are configured to sandwich and convey a receipt A as a paper sheet passing between the opposed rollers.

  A stopper pin 25 is fixed to one end of the drive shaft 21 as a shaft locking portion that protrudes to the rotation radius at a part of the rotation circumference.

  A pulley 26 is rotatably arranged on the drive shaft 21 at a position between the stopper pin 25 and the transport roller 22. The pulley 26 is provided with a protrusion 26a (see FIG. 5) as a drive locking portion on a part of the rotation circumference on the surface on the stopper pin 25 side, and a drive belt 27 as a rotation drive means is applied to the outer periphery. ing. For this reason, the pulley 26 is rotationally driven and stopped by the drive belt 27, and the protrusion 26a is also rotated and stopped accordingly.

In addition, a rotating disk 29 is rotatably disposed on the drive shaft 21 at a position between the pulley 26 and the stopper pin 25. The rotary plate 29 is provided with a protrusion 29a (see FIG. 5) as a drive side contact portion on a part of the rotation circumference on the surface on the pulley 26 side, and the rotation circumference on the surface on the stopper pin 25 side. A projection 29b (see FIG. 5) is provided as a shaft side contact portion in part. Accordingly, the rotating disk 29 has protrusions 29a and 29b on both sides in the axial direction. Note that the protrusions 29a and 29b are provided at the same position on both surfaces of the rotating disk 29 and have the same phase. They may be provided at different positions in the rotational circumferential direction. In this case, the thickness can be made constant by, for example, resin molding.

  The protrusion 26a of the pulley 26 and the protrusion 29a of the rotating disk 29 are provided at the same distance in the radial direction from the axis of the drive shaft 21 serving as the rotating shaft. It is configured so that relative rotation is not possible.

  Further, the protrusion 29b of the turntable 29 and the stopper pin 25 of the drive shaft 21 are provided at the same distance in the radial direction from the axis of the drive shaft 21 serving as the rotation shaft. They are configured to abut against each other so that they cannot rotate further.

  The pulley 26, the turntable 29, and the stopper pin 25 are adjacently arranged in this order on the same axis from the inside of the drive shaft 21 to the outside, and can rotate relative to each other by a predetermined range. That is, the pulley 26 and the turntable 29 are relatively rotatable until the protrusion 26a and the protrusion 29a provided on the opposing surfaces are separated from the contact of one surface and the opposite surfaces contact. The rotating plate 29 and the stopper pin 25 can rotate relative to each other until the protrusion 29b and the stopper pin 25 are separated from the contact on one side and the opposite surfaces are in contact.

  The drive shaft 21 may be provided with appropriate displacement preventing means such as an E-ring (not shown) so that the pulley 26 is not separated from the stopper pin 25 by a predetermined distance or more. Accordingly, it is possible to reliably perform the locking of the relative rotation by the contact of the protrusion 26a and the protrusion 29a and the locking of the relative rotation by the contact of the protrusion 29b and the stopper pin 25.

  When the receipt discharging unit 20 configured as described above discharges the receipt A, the driving belt 27 is driven in the B direction (see FIG. 4) by power not shown, and the pulley 26 is rotated in the C direction. When rotating, the protrusion 26a hits the protrusion 29a of the rotating disk 29, rotates the rotating disk 29, and further the protrusion 29b hits the stopper pin 25 to rotate the drive shaft 21, and the receipt A is discharged. At this time, as shown in the explanatory diagram of FIG. 7, the positional relationship among the stopper pin 25, the protrusion 26a, and the protrusion 29a is such that the protrusion 26a and the protrusion 29a are in contact with each other, and the protrusion 29b on the back side of the protrusion 29a is in contact with the stopper pin 25. ing. For this reason, the rotational driving force by the drive belt 27 is transmitted in the order of the pulley 26, the rotating disk 29, and the stopper pin 25, and the pulley 26, the rotating disk 29, and the stopper pin 25 rotate together.

  When the driving of the driving belt 27 in the B direction is stopped, the pulley 26, the rotating disk 29, and the stopper pin 25 stop rotating in this contact state.

  At this time, a part of the receipt A is discharged from the receipt handling port 3 of the receipt printer 13, and the remaining part is sandwiched between the conveyance roller 22 and the driven roller 24 in the receipt printer 13. As a result, the receipt A is held in a detachable state, and is prevented from being blown by the wind or the like before being extracted by the user.

Further, the amount of receipt A discharged in this state (the length protruding from the receipt handling port 3) is such that the card ejected from the card handling port 4 of the card reader 14 is not completely hidden. It has been adjusted. A part of the card ejected from the card handling port 4 of the card reader 14 is also ejected from the card handling port 4 and the remaining part is held in the card reader 14. When the operator pulls out a long receipt A in the Z direction. The conveyance roller 22 and the drive shaft 21 are rotated in the direction C (see FIG. 7) from the state shown in FIG. 8A to the state shown in FIG. At this time, since the stopper pin 25 rotates (idle) in a direction away from the protrusion 29b, the rotating disk 29 and the pulley 26 do not rotate. For this reason, the operator can pull out with a very light force without being affected by the load of the drive belt 27 or the load of the power connected to the drive belt 27.

  When the drive shaft 21 provided with the stopper pin 25 further rotates, as shown in FIG. 8C, the stopper pin 25 is once separated from the projection 29b of the rotating disk 29, and the stopper pin 25 re-contacts the projection 29b from the opposite direction. To do. At this time, as shown in FIG. 8D, the rotating disk 29 freely rotates in the rotational direction of the drive shaft 21, and can be extracted with a very light force.

  When the receipt A is further extracted, the drive shaft 21 having the conveying roller 22 and the rotating disk 29 are further rotated (idled) in the direction C (see FIG. 7), and the protrusion 29a of the rotating disk 29 is moved. The pulley 26 does not rotate until it comes into contact with the protrusion 26a of the pulley 26, and can be extracted with a very light force.

  If further rotation is performed, the protrusion 29a of the rotating disk 29 contacts the protrusion 26a of the pulley 26 as shown in FIG. 8 (E).

  Therefore, in this method, the rotation amount that the conveyance roller 22 rotates relative to the drive shaft 21 is the sum of the rotation amount X of the drive shaft 21 and the rotation amount Y of the turntable 29 as shown in FIG. It becomes. Thereby, a rotation amount close to two rotations can be secured.

  When the maximum rotation that allows extraction with a light force is performed in this way, as shown in the explanatory view of FIG. 9, the protrusion 26a and the protrusion 29a, the protrusion 29b, and the stopper pin 25 come into contact with each other and rotate. Locked.

  With the above configuration and operation, it is possible to ensure the ease of extracting a long receipt. That is, the range in which the drive shaft 21 can rotate without rotating the pulley 26 can be increased.

  As a result, it is possible to print a large amount of information on the receipt without increasing the width of the receipt while ensuring the ease of extracting the receipt A. Thereby, the problem that the width of the receipt printer becomes large and the apparatus becomes large can be avoided.

  In addition, since a large amount of information can be printed without reducing the size of the character, the problem that it is difficult to read the character can be avoided.

  Further, since the distance at which the receipt can be pulled out with a light force can be increased without increasing the size of the conveying roller, the problem that the entire apparatus becomes larger with an increase in the size of the conveying roller can be avoided.

  Also, since it is not necessary to weaken the clamping force of the roller itself and slip the conveyance roller and receipt to lighten the extraction force, reducing the clamping force will cause a problem of jamming due to a decrease in conveyance performance. Can be avoided.

  In addition, since it is not necessary to increase the receipt discharge amount (the length that protrudes from the receipt handling port 3) to reduce the pull-out amount, the receipt hangs without maintaining the posture, and it is difficult to grasp the card. This can avoid the problem that the card is covered and hidden when it is ejected over the card.

FIG. 10 is a perspective view showing a receipt discharge portion 40 of another embodiment.
In the receipt discharging unit 40, a plurality (N) of rotating plates 29 are arranged between the stopper pin 25 and the pulley 26 on the drive shaft 21. The plurality of turntables 29 are arranged adjacent to each other. The adjacent rotating disks 29 stop rotating relative to each other when the respective protrusions 29a and 29b rotate relative to each other from the state where the protrusions 29a and 29b are in contact with each other until they contact each other. Therefore, the rotation range is regulated by the protrusions 29a and 29b.

  Thus, by installing N rotating plates 29, the amount of rotation Y of the rotating plate 29 becomes N times, and the length of the receipt that can be extracted with a light force can be further increased.

  Since other configurations and operations are the same as those of the first embodiment, the same reference numerals are given to the same elements, and detailed descriptions thereof are omitted.

  With the above configuration, the receipt discharge unit 40 of the second embodiment can obtain the same effect as that of the first embodiment, and can cope with a longer receipt than the first embodiment.

  In the illustration of the second embodiment, the number of the rotary plates 29 is three, but the present invention is not limited to this, and a plurality of rotary plates 29 can be provided. In this case, the length of the receipt that can be handled by the number of the rotary plates 29 can be increased.

  The present invention is not limited only to the configuration of the above-described embodiment, and many embodiments can be obtained.

  The present invention can be used for various devices in which a part of the paper sheet is discharged from the discharge port and the remaining part is held in the apparatus, and the paper sheet is finally extracted by the user's hand from this state. it can.
