JP-A-7-303511 (from paragraphs [0027] to [0035], FIG. 7)

  In the above-described conventional pollutant jetting device for banknote fouling, gas is supplied from one gas tube to a cylinder chamber provided on the ink discharge side of the ink storage container with one resin tube, and further supplied to the cylinder chamber with the other resin tube. The gas thus supplied is supplied into the outer container to shrink and deform the inner container. In this way, gas is supplied from the gas cylinder to the cylinder chamber and the outer container using two resin tubes. Therefore, a mechanism necessary for supplying gas from a gas cylinder and ejecting ink onto a banknote bundle is complicated, and as a result, a long time is required from sending gas from the gas cylinder to ejecting ink onto a banknote bundle. There was a problem that it took a long time and the apparatus was enlarged.

  In order to solve the above-mentioned problems, the solution means provided in the present invention includes: a container; a pressurizing means disposed in the container for generating a pressure in response to an activation signal; and a connection port formed on the container and connected to the outside. A discharge port that becomes the inside of the container, and is disposed between the pressurizing means and the discharge port, and is provided with a flexible liquid reservoir containing a liquid, and in the container, A piston disposed between the pressurizing means and the liquid reservoir, and moved by a pressurizing force from the pressurizing means to press the liquid reservoir; and in the container, the liquid reservoir; A breakage means disposed between the discharge port and damaging the liquid reservoir, and by applying pressure from the pressurization means, the piston is moved to press the liquid reservoir against the breakage means. Break and push liquid out of the liquid reservoir Is for ejecting from the outlet.

  According to the present invention, the applied pressure from the pressurizing means can be transmitted to the piston without passing through the tube, and the piston can be moved toward the liquid reservoir. Then, the piston presses the liquid reservoir against the breakage means to break it, pushes the liquid from the liquid reservoir, and ejects it from the discharge port. Thus, the liquid can be ejected with a simple structure. As a result, it is possible to shorten the time required to eject the liquid after the pressurizing means generates the applied pressure. Moreover, since the number of parts can be reduced, the apparatus can be miniaturized.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the element common to each drawing. 1 is a perspective view showing a configuration of a banknote storage of the embodiment, FIG. 2 is a perspective view showing a configuration of a cylinder of the embodiment, FIG. 3 is a partially broken perspective view showing a nozzle of the embodiment, and FIG. FIG. 5 is a partially broken sectional view showing the nozzle of the embodiment, and FIG. 5 is an explanatory view showing the relationship between the cylinder and the piston of the embodiment.

  An automatic transaction apparatus (not shown) is provided with a banknote deposit and withdrawal unit. A customer service section, which is a unit that discharges banknotes as a medium to a customer or accepts banknotes input from a customer, is provided on the front upper portion of the banknote deposit / withdrawal section.

  In FIG. 1, a plurality of banknote storages 3 for storing banknotes 2 by denomination are provided at the bottom of the banknote depositing / withdrawing unit, and the transport path through which the banknotes 2 are transported from the customer service unit to the banknote storage 3. Is formed. The conveyance path is configured by a roller and a conveyance belt for conveying the banknote 2, and the conveyance path between the customer service unit and the banknote storage 3 has two sheets of authenticity, correctness, front and back of the fed banknote 2. A discrimination unit for discriminating and detecting the above overlap and skew is provided.

  All banknote storages 3 are each provided with an ink ejecting apparatus 1 which is a liquid ejecting apparatus. The ink ejecting apparatus 1 includes a cylindrical cylinder 5 as a container, a tube 4 connected to the cylinder 5, and a nozzle 6 connected to the tube 4. The nozzle 6 is arranged in a state extending along the stacking direction of the banknotes 2.

  1 and 2, a discharge port 11 connected to the tube 4 and serving as a connection port with the outside is formed on the side surface of the cylinder 5, and the flexibility increases toward the rear from the discharge port 11. A liquid storage device that is formed of a member capable of expanding and contracting, has a certain degree of viscosity, has a high resistance to dissolution, and has a built-in ink or solvent (hereinafter referred to as a special ink) that is a liquid for fouling banknotes. An ink pack 7 that is a container, a cylindrical piston 8 that pushes the ink pack 7 toward the nozzle 6, and a gas that pushes the special ink out of the cylinder 5 while operating the piston 8 toward the ink pack 7. A gas generator 9 as a pressurizing means is built in. A cutter 10 is provided around the discharge port 11 in a state where a blade protrudes from the inner wall of the cylinder 5 toward the ink pack 7, and the ink pack 7 is cut and damaged by the cutter 10.

  In the ink ejecting apparatus 1 configured as described above, the piston 8 is moved in the direction of the nozzle 6 by being pushed by the pressure of the gas discharged from the gas generator 9, and the ink pack 7 is pushed in the direction of the nozzle 6. . As a result, the ink pack 7 comes into contact with the cutter 10 and is further pressed to be pressed against the cutter 10 and partially damaged. As a result, the special ink filled in the ink pack 7 leaks out and is pressed further, so that the ink pack 7 discharges and contracts while collapsing. As a result, the special ink is forced out of the ink pack 7. The special ink discharged from the ink pack 7 reaches the nozzle 6 from the discharge port 11 through the tube 4.

  As shown in FIGS. 1 and 2, the gas generator 9, the piston 8, the ink pack 7, the cutter 10, and the discharge port 11 are arranged on a straight line. Thereby, the applied pressure from the gas generator 9 can be transmitted to the piston 8 without going through the tube, and the piston 8 can be moved toward the ink pack 7. Then, the piston 8 presses the ink pack 8 against the cutter 10 to break it, and the special ink can be pushed out from the ink pack 7 and ejected from the discharge port 11.

  As shown in FIGS. 3 and 4, the nozzle 6 has a plurality of injection ports 14, and a slit plate 20 is fixed to the nozzle 6 by a double-sided tape 19. A hole 21 and a slit 15 are formed at positions of the double-sided tape 19 and the slit plate 20 facing the injection port 14, respectively. The special ink ejected from the ejection port 14 is ejected to the banknotes 2 accumulated through the holes 21 and the slits 15.

  The diameter of the hole 21 formed in the double-sided tape 19 is larger than the diameter of the ejection port 14, and the special ink ejected from the ejection port 14 is ejected linearly from the ejection port 14 to the outside. In addition to those, there are also those that are once accumulated in a state where the diameter is expanded in the larger hole 21 and then injected to the outside. As a result, the special ink can be ejected over a wider range as compared with the case of only ejecting linearly from the ejection port 14.

  Moreover, as shown in FIG. 1, in the banknote storage 3, it extends in the stacking direction of the banknotes 2 so as to face the nozzles 6, and the fibers are in positions where the banknotes 2 are partially in contact. The brush 13 which is the transmission member formed in is provided. The brush 13 transmits special ink ejected from the ejection port 14 to the banknote 2. As a result, the special ink ejected from the nozzle 6 adheres directly to the banknote 2 from the nozzle 6 and also attaches to the banknote 2 via the brush 13.

  Also, if the piston 8 tilts obliquely during movement and gets stuck on the inner wall of the cylinder 7 and stops moving, the pressure in the cylinder 7 rises and the cylinder 8 cannot withstand the internal pressure of the gas released from the gas generator 9. 7 may burst. In order to prevent this, as shown in FIG. 2, the piston 8 is formed with a hole 8a as pressure reducing means. The size of the hole 8a is such that the ink pack 7 is sufficiently pressed against the cutter 10 only by the pressure of the gas that escapes from the hole 8a to damage the ink pack 7, and the ink pack 7 is pressed to push out the special ink. When the piston 8 does not move or the piston 8 does not move or stops in the middle of movement without being moved to a predetermined position, the gas generator 9 and the piston 8 The gas that fills the space has a size that allows the gas to escape until the gas does not exceed the pressure resistance of the cylinder 7.

  The hole 8a does not need to be formed at the center of the piston 8 if the ink pack 7 can be sufficiently pressed against the cutter 10 only by the pressure of the gas that escapes from the hole 8a and further compressed and deformed. A plurality of holes 8a may be formed.

  Alternatively, as shown in FIG. 5, instead of forming the hole 8a, the piston 8 is tilted while the inner diameter D of the cylinder 5 is tilted in order to prevent the piston 8 from tilting during movement and being caught by the inner wall of the cylinder 7. It may be formed larger than the maximum length L of the piston 8. With this configuration, the piston 8 can be moved in a tilted state, and the cylinder 5 can be prevented from bursting.

  As shown in FIG. 2, the banknote storage 3 is also provided with a switch 17 that is a destruction detecting means, and a signal line 18 that electrically connects the switch 17 and the gas generator 9 of the ink ejecting apparatus 1. ing. The switch 17 detects an impact received by the bill storage case 3, and when the impact exceeds a predetermined value, an activation signal serving as a trigger for preventing bill theft is sent to the gas generator 9 via the signal line 18. Send.

  Next, the operation when the banknote storage 3 in the above configuration is attacked from the outside and the ink ejecting apparatus 1 ejects special ink will be described. 6 and 7 are perspective views showing a state in which the special ink ejected from the nozzle according to the embodiment adheres to the banknote, FIG. 8 is a perspective view showing the cylinder with the piston tilted according to the embodiment, and FIG. The perspective view which shows the state which the special ink ejected from the nozzle of embodiment adhered to the banknote, FIG. 10 is a partially broken perspective view which shows the nozzle of the other structure of embodiment, FIG. The perspective view which shows the state which the special ink ejected from the nozzle of the structure of this adhered to the banknote, FIG. 12 is a partially broken perspective view which shows the nozzle of the other structure of embodiment.

  In FIG. 1 and FIG. 2, when the banknote storage 3 is stolen at the time of transportation or the automatic transaction apparatus is stolen, the door (not shown) of the banknote storage 3 is locked, so the banknote storage 3 is The attack to destroy is received from the outside by a bar. Then, the switch 17 detects an impact received by the banknote storage 3, and when the impact exceeds a predetermined value, the banknote storage 3 is destroyed and is sent to the gas generator 9 via the signal line 18. In response to this, an activation signal is transmitted.

  When the gas generator 9 receives the activation signal from the switch 17, the gas generator 9 releases a predetermined amount of gas. Note that the amount of gas released upon receiving a single activation signal is the amount necessary to move the piston 8 to a predetermined position where the ink pack 7 is crushed, and the special ink is applied to the tube 4 and the nozzle 6. It is more than the amount necessary for extruding from the tube 4 and the nozzle 6 so as not to remain.

  When the gas is released, it is pressed by this gas, and the piston 8 is moved in the direction of the nozzle 6 and moves to push the ink pack 7 in the direction of the nozzle 6. As a result, the ink pack 7 comes into contact with the cutter 10 and is pressed further against the cutter 10 to be partially damaged. As a result, the special ink filled in the ink pack 7 leaks out and is pressed further, so that the ink pack 7 discharges and contracts while collapsing. As a result, the special ink is forced out of the ink pack 7. Further, in addition to the pressing force from the piston 8, the gas passing through the hole 8a formed in the piston 8 and the gas reaching from the gap between the piston 8 and the inner wall of the cylinder 5 squeeze the ink pack 7, and the ink pack 7 further contracts. Then push out the special ink. Thereby, the special ink in the ink pack 7 is discharged to the outside without remaining.

  The pushed special ink reaches the nozzle 6 from the discharge port 11 through the tube 4, and the banknotes 2 accumulated from the ejection port 14 of the nozzle 6, the hole 21 of the double-sided tape 19, and the slit 15 of the slit plate 20. Is injected against. The ejected special ink enters the conveyance surface of the banknote 2 through the gap between the stacked banknotes 2 and adheres to the banknote 2 as shown in FIG.

  Thus, the banknote 2 is soiled by the special ink 12, and the soiled banknote 2 cannot be used in a store, an automatic transaction apparatus, or a vending machine. As a result, the prevention of the theft of the banknote 2 by equipment destruction and the deterrent effect can be acquired.

  Moreover, when the special ink 12 is ejected from the nozzle 6 by providing the brush 13 made of fiber at a position in contact with the stacked banknotes 2, the special ink 12 as shown in FIG. It adheres to the bill 2 directly from the nozzle 6 and also from the brush 13 in a state where the special ink 12 is adhered. When the special ink 12 adheres to the banknote 2 via the brush 13, the special ink 12 is in contact with the banknote 2 for a long time, and the time for the special ink 12 to soak into the banknote 2 becomes longer. As a result, the special ink 12 can be attached to the banknote 2 over a wider range than when the special ink 12 is attached to the banknote 2 without providing the brush 13 as shown in FIG. Further, when the special ink 12 travels through the fibers of the brush 13 and adheres to the bill 2, the special ink is uniformly applied to the portion of the bill 2 where the special ink 12 ejected from the nozzle 6 does not reach directly and the portion that is difficult to be stained. 12 can be attached.

  Further, in addition to the special ink 12, gas also escapes from the discharge port 11 to the outside. Even when the crushed ink pack 7 covers the discharge port 11, there is a gap between the ink pack 7 and the discharge port 11, so that the gas passes through the gap from the discharge port 11 to the outside. Exit.

  The gas discharged from the gas generator 9 continues to be released until a predetermined amount of discharge is completed even after all of the special ink 12 is discharged from the ink pack 7, so that it is pushed out by the gas discharged from the discharge port 11 and is tubed. 4 and the ink does not remain in the nozzle 6. Therefore, the amount of the special ink 12 filled in the ink pack 7 may be only an amount necessary for fouling the banknote 2 without considering the amount of the special ink remaining in the tube 4 and the nozzle 6. As a result, it is not necessary to fill the special ink 12 in an amount larger than that necessary for fouling the banknote 2, so that the special ink 12 is not wasted.

  Since the hole 8a is formed in the piston 8, as shown in FIG. 8, before the piston 8 moves to a predetermined position, the piston 8 tilts obliquely and catches on the inner wall of the cylinder 5 to stop the movement. However, the ink pack 7 is sufficiently pressed against the cutter 10 only by the pressure of the gas passing through the hole 8a to be damaged, and the ink pack 7 is contracted by applying the pressing force to force the special ink 12 to the ink pack. It can be extruded from 7 and further from the cylinder 5.

  Further, even when the piston 8 does not operate or when the piston 8 does not move to a predetermined position and stops in the middle of movement, the gas passes through the hole 8a so as not to exceed the pressure resistance of the cylinder 5, and the discharge port 11 Therefore, it is possible to prevent the gas from filling the narrow space between the gas generator 9 and the piston 8, and thus to prevent the pressure in the cylinder 5 from rising. As a result, it is possible to prevent the cylinder 5 from bursting without being able to withstand the internal pressure of the gas filling the space between the gas generator 9 and the piston 8.

  Alternatively, as shown in FIG. 5, instead of forming the hole 8a, if the inner diameter D of the cylinder 5 is formed larger than the maximum length L of the tilted piston 8, the piston 8 tilts during movement. Even in this case, the piston 8 is moved while being tilted, the ink pack 7 is pressed against the cutter 10, and a part of the ink pack 7 can be damaged by the cutter 10. As a result, the special ink filled in the ink pack 7 leaks out, and the piston 8 presses the ink pack 7 to discharge the special ink 12 and contract. As a result, the special ink 12 filled in the ink pack 7 is forcibly pushed out of the ink pack 7. Further, in addition to the pressing force from the piston 8, gas reaching from the gap between the piston 8 and the inner wall of the cylinder 5 squeezes the ink pack 7, and the ink pack 7 further contracts to push out the special ink. The special ink pushed out from the cylinder 5 in this way reaches the nozzle 6 through the tube 4 and is ejected from the nozzle 6 to the banknote 2.

  In addition, as shown in FIG. 9, when the nozzle 6 cannot be provided with the height substantially the same as the stacking height of the banknote 2, there is a possibility that the special ink 12 cannot be attached to all the banknotes 2 stacked. . In order to prevent this, as shown in FIG. 10, the upper surface 6a, which is the end of the nozzle 6, is formed to be inclined in the stacking direction of the bills 2, and the injection port 14 is formed on the upper surface 6a. A hole 21 is formed in the double-sided tape 19 at a position opposed to 14, and a slit 15 is formed in the slit plate 20. The special ink 12 can be ejected obliquely upward from the upper surface 6a. As a result, the special ink 12 ejected from the upper surface 6 a of the nozzle 6 reaches a position higher than the height of the nozzle 6. Therefore, since the special ink 12 can be ejected to the upper ink ejection range B in addition to the conventional ink ejection range A, the nozzle 6 is not provided for the height of the banknote 2. However, the special ink 12 can be reliably attached to the banknotes 2 stacked at positions where the nozzles 6 do not face each other.

  Moreover, as shown in FIG. 11, the lower surface 6b which is the edge part of the nozzle 6 is also inclined and formed in the banknote 2 direction similarly to the upper surface 6a, and forms an injection port. As a result, the special ink 12 can be ejected obliquely downward from the lower surface 6 b of the nozzle 6, and the special ink 12 ejected from the lower surface 6 b of the nozzle 6 reaches a position lower than the height of the nozzle 6. In addition to the ink ejection range A and the ink ejection range B, the lower ink ejection range C is added as the ejection range of the special ink 12. As a result, the special ink 12 can be reliably attached to the banknotes 2 stacked at positions where the nozzles 6 do not face each other. As a result, the special ink 12 can be reliably attached to all the stacked banknotes 2.

  As another means for reliably attaching the special ink 12 to all the stacked banknotes 2 when the nozzles 6 cannot be provided at substantially the same height as the banknotes 2, as shown in FIG. The diameter of the ejection port 14 formed in 6 is increased, the amount of the special ink 12 to be ejected is increased, and the length of the slit 15 is increased to widen the ink ejection range E when the special ink 12 is ejected. By increasing the amount of the special ink 12 to be ejected and expanding the ejection range, the special ink 12 can be reliably attached to the banknotes 2 that are stacked at positions where the nozzles 6 do not face each other. . As a result, the special ink 12 can be reliably attached to all the stacked banknotes 2.

  Further, in the injection port 14 of the nozzle 6, the diameters of the upper and lower injection ports 14 may be formed larger than the diameter of the central injection port 14. By forming the ejection ports in at least two sizes in this way, a large amount of special ink 12 can be ejected from the upper end and the lower end of the nozzle 6, and the ejection range can be further expanded upward and downward. As a result, the special ink 12 can be reliably attached to the banknotes 2 stacked at positions where the nozzles 6 do not face each other. As a result, the special ink 12 can be reliably attached to all the stacked banknotes 2.

  Furthermore, an injection amount adjusting slide member in which a plurality of holes having different diameters are formed may be provided in the nozzle 6 so as to be slidable. As a result, the ejection amount adjustment slide member is slid so that the large-diameter hole formed in the ejection amount adjustment slide member is opposed to the ejection port 14 of the nozzle 6, and the special ink 12 is ejected in this state. A large amount of the ink 12 can be ejected. On the other hand, if the ejection amount adjusting slide member is slid so that the small-diameter hole faces the ejection port 14 of the nozzle 6 and the special ink 12 is ejected in this state, the special ink 12 can be ejected in a small amount. If the ejection amount adjusting slide member is provided in this way, the size of the ejection port can be changed with a simple mechanism, and the ejection amount of the special ink 12 can be adjusted.

  The gas generator 9 may be a bag-like member containing gas, and the bag-like member may be ruptured to release the gas. Alternatively, the piston 8 may be moved by the energy of the explosive instead of the gas generator 9. Alternatively, the piston 8 may be moved using an electric actuator such as a motor or a solenoid.

  Moreover, the ink for fouling the banknote 2 should just be able to stain the banknote 2 in an unusable state, and may be a printing ink. Further, in order to enable the device into which the banknote 2 is inserted to recognize that it is a stolen banknote, the wireless ink tag, carbon particles, or magnetic particles may be mixed in the special ink 12. .

  When a wireless IC tag is mixed in the special ink 12, information indicating that it is a stolen banknote is written in the wireless IC tag, and information from the wireless IC tag is sent to a device into which the banknote 2 is inserted. Reading means for reading is provided. Thereby, when the banknote 2 with the wireless IC tag attached is inserted into the apparatus, the reading unit reads information indicating that it is a stolen banknote from the wireless IC tag, and the apparatus easily recognizes that it is a stolen banknote. be able to.

  Moreover, the banknote discrimination part provided in the apparatus in which the banknote 2 is inserted uses optical outputs, such as visible light, infrared rays, and ultraviolet rays, or a magnetic output, in order to discriminate | determine whether a banknote is a forged ticket. is doing. Therefore, if carbon particles or magnetic particles are mixed in the special ink 12, when the banknote 2 to which such special ink 12 is attached is inserted into the apparatus, the carbon particles or magnetic particles are detected. The waveform of optical output or magnetic output is different from the output of normal banknotes. Thereby, the banknote discrimination part can recognize the inserted banknote 2 as an abnormal banknote.

  As described above, in the embodiment of the present invention, the ink ejecting apparatus 1 includes the cylinder 5, the gas generator 9 disposed in the cylinder 5, the discharge port 11 formed in the cylinder 5, the gas generator 9 and the discharge. An ink pack 7 disposed between the outlet 11, a piston 8 disposed between the gas generator 9 and the ink pack 7, and a cutter 10 disposed between the ink pack 7 and the discharge port 11; The pressure applied by the gas from the gas generator 9 can be transmitted to the piston 8 without passing through the tube, and the piston 8 can be moved toward the ink pack 7. Then, the piston 8 presses the ink pack 7 against the cutter 10 to cause damage, and the special ink 12 is pushed out from the ink pack 7 and ejected from the discharge port 11. In this way, the special ink 12 can be ejected with a simple structure. As a result, the time required to eject the special ink 12 after the gas generator 9 releases the gas can be shortened. Moreover, since the number of parts can be reduced, the apparatus can be miniaturized.

  Further, since the ink pack 7 is contracted by the gas pressure and the special ink 12 is forcibly discharged from the cylinder 5, the special ink is applied to the banknote 2 regardless of the arrangement state of the device incorporating the ink ejecting device 1. 12 can be sprayed uniformly. As a result, the banknote 2 can be soiled uniformly.
