Description

  The present invention relates to a banknote storage, a banknote processing apparatus, and a money processing apparatus, and more particularly, a miniaturized banknote that can be mounted on a main body apparatus having a small built-in space, such as an oil pump installed in a self-service gasoline station. The present invention relates to a storage, a banknote processing apparatus, and a money processing apparatus.

  For example, at a gas station or the like, cash deposit / withdrawal processing is performed according to the amount of fuel supplied. In particular, in a self-service type gas station, the user himself is responsible for everything from refueling to liquidation. Therefore, it is desirable for the user to be able to perform all operations from refueling to clearing at the place where the refueling is performed. However, since the size of the oil pump is determined to some extent with respect to the cash deposit / withdrawal process, there are restrictions on the space for incorporating the bill and coin handling device.

  Therefore, in the conventional oil supply pump, only the banknote processing device for depositing and withdrawing banknotes is mounted. When there is a small change or when clearing with coins, the clearing provided in another place The change is settled on the machine or in the store.

  The clearing machine or the like is provided with a coin processing device capable of performing change processing, and determines the denomination of the received coin and stores it according to the determined denomination. The corresponding denomination and number of coins can be paid out as change.

  In such a coin processing device, in order to reuse the received coins as change, the coin storage has a coin tube of a denomination and is stored in the denomination. It is equipped with a sorting device that sorts coins that have been deposited in advance. The coins sorted by the sorting device fall into a coin tube arranged so as to open at the lower part thereof and are stored in denominations.

  When change is necessary, the required number of coins is paid out one by one from the tube of the corresponding denomination in the storage, and the paid out coins are transported to the coin outlet at the coin dispensing transport part, Withdrawal.

  Such a coin processing device is capable of handling all denominations of coins in circulation, and adopts the same equipment configuration as a change machine operating in conjunction with a cash drawer used in supermarkets and the like. ing.

  On the other hand, even in the banknote processing device mounted in the oil pump, when the received banknote is identified and stored in the banknote storage and change is required, the change banknote of the corresponding denomination is required from the banknote storage. It is configured to pay out the number of sheets. Such a banknote processing apparatus has a plurality of banknote storages for storing the received banknotes by denomination after discrimination. At least one of the banknote storage has a recycling function that allows the stored banknotes to be paid out so that the banknotes deposited and stored in the banknote storage can be reused as change.

  Such a banknote processing device can handle banknotes of all denominations in circulation, and adopts the same equipment configuration as a deposit / withdrawal machine mounted on a ticket vending machine or banknote automatic teller machine. Has been. Each denomination banknote storage has a stage inside, and the pushed banknotes are stored in a stacked state on the stage. The stage can be raised and lowered according to the number of stored bills, and a pantograph type mechanism is known as a mechanism for raising and lowering the stage (see, for example, Patent Document 1).

  The banknote storage which has a recycle function is provided with the banknote delivery part which pays out the banknote accommodated in the upper part. This banknote feeding part has a roller provided with a high friction member in a part in the circumferential direction, and the roller is in contact with the uppermost banknote stacked on the stage. The banknote is kicked out in the creeping direction so as to be fed out from the banknote storage (see, for example, Patent Document 2).

  When the bill is paid out, the stage is raised and the bills stacked thereon are pressed against the roller so that contact friction occurs between the roller and the bill. If this pressing force is too strong, a plurality of banknotes are fed together with the uppermost banknote by friction between the banknotes. If it is too weak, the rollers are idle and the banknotes cannot be fed out. For this reason, the pressing force by raising the stage needs to be properly maintained. Still, since the banknotes differ greatly in the inter-banknote friction depending on the usage state by distribution, a plurality of banknotes may be fed out. For this reason, the banknote outlet of the banknote storage is provided with a roller that separates a plurality of banknotes brought together and passes only the topmost one. After the upper banknote passes, the roller used to feed out the banknote is reversed and returned to the banknote storage. At this time, the stage is lowered to secure a space for returning the bills.

  Moreover, since the downward force according to the number of sheets is added to the stage by the dead weight of the banknotes placed on the stage, it is necessary to increase the force pushed up as the number of banknotes increases. Furthermore, since the distributed banknotes are not stacked in close contact with each other, the accumulated value of the space existing between the banknotes increases as the number of stored sheets increases. Therefore, the stage needs a push-up force that crushes such a space as the number of stored banknotes increases and pushes the uppermost banknote properly against the roller. Such raising and lowering of the stage is performed by a motor, and by controlling the driving torque of the motor, the bill on the stage is pressed against the roller with an appropriate force, or the axis at the crossing position of the pantograph is used. A torsion spring is wound, and the torsion spring pushes up the pantograph so as to press the bill against the roller.

At the time of feeding, banknotes that have passed through a roller that separates banknotes and are fed out in a stacked manner cannot be withdrawn as they are, so such banknotes are stored in a reject box. Since such a reject store is dedicated for storage, it is desirable that reject banknotes are not generated as much as possible.
JP 2002-87711 A (FIG. 1) Japanese Patent Laid-Open No. 10-95540 (FIG. 1)

  However, since the bill processing apparatus incorporated in the oil pump as installed at the gas station has a limited installation space, the bill storage unit having a recycling function raises and lowers the stage when the stored bill is fed out. Since it is difficult to install a motor to cause the stage to be pushed up by a spring, in that case, it is difficult to obtain a controlled proper pressing force from one sheet to the maximum number that can be stored, Therefore, there was a problem that rejected banknotes are likely to be generated.

The second safe is a stage on which a bill is placed so that a force for pressing the bill against a roller for feeding out the bill is generated by an urging means composed of a torsion spring, a tension spring, and a leaf spring. The size can be reduced by eliminating the need for a mechanism for raising and lowering. Furthermore, by optimizing the setting of the spring that constitutes the urging means, it is possible to make the pressing force to the rollers appropriate when there are a small number of stored banknotes, so that when the banknotes are fed, Because the number of banknotes that are fed out together with the top banknote due to friction between banknotes can be reduced, the number of rejected banknotes can be reduced, and the number of storages in the withdrawal reject box that stores reject banknotes can be reduced. Therefore, a banknote processing apparatus can be reduced in size. In addition, for the coin processing device, a lifter unit for transferring coins, a coin distribution unit, and a dispensing coin transfer unit are disposed so as to surround a plurality of change tubes arranged side by side in the depth direction. The lifter part is arranged at a position close to the coin slot, and the coin identifying part is arranged in the middle of the lifter part. Thereby, the flow line of the coin which circulates the inside of a coin processing apparatus was minimized, and the coin processing apparatus was able to be comprised compactly. Thus, since each of the banknote processing apparatus and the coin processing apparatus can be reduced in size, the banknote processing apparatus and the coin processing apparatus can be incorporated together even in a small installation space.

  The banknote storage of the present invention is configured such that the force for pressing the banknotes against the roller for paying out the banknotes is generated by the urging means composed of a torsion spring, a tension spring, and a leaf spring. A mechanism for raising and lowering the stage is unnecessary. In addition, by optimizing the settings of these springs, it is possible to make the pressing force to the rollers appropriate when there are a few to many stored banknotes. Since it is possible to reduce the number of banknotes that are fed out together with the highest banknote, the generation factor of reject banknotes can be reduced.

  Moreover, according to the banknote processing apparatus of the present invention, the second safe having a recycling function does not use a mechanism for moving the stage up and down, and is configured by a torsion spring, a tension spring, and a leaf spring, thereby reducing the size. It becomes possible. In addition, by optimizing the settings of these springs, the generation factor of reject banknotes can be reduced, so that the withdrawal reject box can be reduced in size.

  Furthermore, according to the money processing apparatus of the present invention, the banknote processing apparatus can handle all denomination banknotes with only two safes, and since the generation of reject banknotes is small, it can be made into a small withdrawal reject box. As for the coin processing device, by arranging the components so that the coins flow in the shortest distance, each of them can be miniaturized, and the bill processing device and the coin processing device are put together in a narrow space of the main unit that handles bills and coins. Can be installed.

  In the depositing operation of the banknote handling apparatus 100, when the deposited banknote is a high-value banknote as a result of the discrimination by the deposited banknote discrimination unit 106, the banknote P is transported by the vertical banknote transport unit and inserted into the mixed banknote storage 109. Is done. At this time, in the pusher portion standby state shown in FIG. 4, the cam 155 is at the bottom dead center and the operation frame 151 is in the state of being lowered most downward in the drawing. Therefore, the bill P is guided by the space formed between the extending portion 142 and the rail 143 at both edges in the direction orthogonal to the conveying direction, and the central portion is placed on the bill pressing portion 145 of the outer frame 141. And inserted into the mixed banknote storage 109.

  When the passage sensor 114 installed at the entrance of the mixed banknote storage 109 detects the passage of the banknote P, the motor 116 operates to rotate the cam 155. When the cam 155 rotates, the cam follower 156 in contact with the cam 155 rises upward in the figure. As a result, the operation frame 151 to which the cam follower 156 is fixed moves up, and the drive unit 152 pushes up the bill pressing unit 145 of the outer frame 141 in contact with the operation frame 152. At this time, the bills P are pushed into the inner frame 140 as shown in FIG. When the cam 155 further rotates beyond the top dead center and makes one revolution, the motor 116 stops and the mixed banknote storage 109 returns to the pusher section standby state shown in FIG. The pushed bills P are stored in the inner frame 140 in a state in which both edges thereof are on the rail 143 and are stacked in the operation direction of the operation frame 151.

FIG. 6 is an explanatory diagram showing a pusher unit standby state when a thousand yen bill is stored, and FIG. 7 is an explanatory diagram showing a pusher unit operating state when a thousand yen bill is stored.
In the depositing operation of the banknote handling apparatus 100, when the deposited banknote is a thousand yen banknote as a result of the discrimination by the deposited banknote discrimination unit 106, the banknote P is transported by the vertical banknote transport unit, and the transport path is made by the gate 113. It is switched and inserted into the thousand yen bill storage 110. At this time, in the pusher portion standby state shown in FIG. 6, the cam 155 is at the bottom dead center and the operation frame 151 is in the state of being lowered most downward in the drawing. Therefore, the banknote P is inserted into the thousand-yen banknote storage 110 in a state where both edges in the direction orthogonal to the transport direction are placed on the rail 149.

  When the passage sensor 115 installed at the entrance of the thousand yen banknote storage 110 detects the passage of the banknote P, the motor 116 operates to rotate the cam 155. When the cam 155 rotates, the cam follower 156 in contact with the cam 155 rises upward in the drawing, and the operation frame 151 is raised. Along with this, the suspension plate 153 rises and lifts the inner frame 146 connected thereto. At this time, since the central part of the banknote P is blocked by the top plate 150, both edge parts get over the rail 149 and are pushed into the inner frame 146 as shown in FIG. When the cam 155 further rotates beyond the top dead center and makes one revolution, the motor 116 stops and the thousand-yen banknote storage 110 returns to the pusher section standby state shown in FIG. The pushed bills P are stored in the inner frame 140 below the rail 149 while being stacked in the operation direction of the operation frame 151.

  The mixed banknote storage 109 and the thousand yen banknote storage 110 each store the banknotes P by one operation frame 151. The operation by the operation frame 151 is performed by the thousand yen banknote storage 110. It is also used at the time of the withdrawal operation of the stored banknote and at the time of the storage operation of the reject banknote accompanying the withdrawal operation.

  That is, when the 1000-yen banknote is withdrawn from the thousand-yen banknote storage 110, the suspension plate 153 of the operation frame 151 lifts the inner frame 146, and the banknote P stored therein is driven by the drive unit 152 of the operation frame 151. And the top plate 150 are pressed against the sub kick roller 117 and the kick roller 118 of the bill feeding portion. The banknotes P pressed against the sub kick roller 117 and the kick roller 118 are fed out from the thousand-yen banknote storage 110 one by one as the sub kick roller 117 and the kick roller 118 rotate. Moreover, the banknote P drawn out from the thousand-yen banknote storage 110 is transported to the withdrawal holding part 112 or the withdrawal reject box 111 according to the result of discrimination by the withdrawal banknote discrimination part 121 provided at the exit. However, when storing in the withdrawal / rejection reject box 111, the inner frame 146 is lifted by the suspension plate 153 of the operation frame 151 as shown in FIG. The height of is high. For this reason, the banknote P conveyed to the withdrawal / rejection warehouse 111 can be smoothly stored in the withdrawal / rejection warehouse 111.

Next, the banknote dispensing operation by the banknote feeding part of the thousand yen banknote storage 110 will be described.
8 is an internal side view showing the banknote storage state of the thousand yen banknote storage, FIG. 9 is an internal side view showing the withdrawal operation state of the thousand yen banknote storage, and FIG. 10 is the banknote return operation of the thousand yen banknote storage. FIG. 11 is a diagram showing a change in the pressing force of the bill during the withdrawal operation of the thousand-yen bill storage, wherein (A) shows a change due to a conventional spring configuration, ) Shows changes due to the spring configuration of the present embodiment.

  The thousand-yen banknote storage 110 has a stage 160 that can move up and down in its inner frame 146. A pantograph 161 is provided between the stage 160 and the bottom of the inner frame 146. The pantograph 161 has a link 162 whose one end is pivotally fixed to the banknote entrance / exit side of the lower surface of the stage 160 and whose other end is movably coupled to the bottom of the inner frame 146 in the horizontal direction; One end of the inner frame 146 is pivotally fixed to the bottom of the banknote entrance side, and the other end has a link 163 coupled to the lower surface of the back side of the stage 160 so as to be movable in the horizontal direction. Another set of links is arranged at a predetermined interval in a direction orthogonal to the direction. A shaft 164 is provided at the intersection of the links 162 and 163.

  Here, the shaft 164 is not the center of the length of the links 162 and 163 but is slightly offset from the center toward the banknote entrance / exit. As a result, when the pantograph 161 extends the longest in the vertical direction, that is, when the stage 160 is positioned directly below the rail 149, the stage 160 is held in the horizontal direction, and the stage 160 is lowered from this state, and the pantograph As 161 contracts in the vertical direction, the back side of the stage 160 can be lowered from the banknote entrance / exit side.

  The pantograph 161 is also provided with a torsion spring 166 on the rotation shaft 165 of the link 162, and urges the link 162 to stand up by rotating counterclockwise around the rotation shaft 165 in the drawing. is doing. The horizontal movement shaft 167 of the link 163 is provided with a tension spring 168 that pulls the link 163 in the direction of the torsion spring 166. These torsion springs 166 and tension springs 168 always urge the stage 160 in the direction of lifting. Further, a leaf spring 169 is fixed to the lower surface of the stage 160 in a slanting manner, and its free end is hooked on the shaft 164 when the stored bills increase and the pantograph 161 contracts in the vertical direction. The urging force of the torsion spring 166 and the tension spring 168 is increased to act.

  A flexible sheet 170 that moves up and down in conjunction with an inner frame 146 that is lifted and lowered by a pusher portion is provided on the bill entrance / exit side end surface of the thousand-yen bill storage 110. The sheet 170 pushes up the stage 160 so that the uppermost banknote P is pressed against the sub kick roller 117 and the kick roller 118 (only the kick roller 118 is shown in FIG. 8), and the upper end is the banknote. It arrange | positions so that it may be located in the width direction both sides of the banknote P so that the delivery direction of P may be interrupted | blocked. Thereby, when the banknote P is fed out by the kick roller 118, a plurality of banknotes may be fed out together with the uppermost banknote P due to friction between the banknotes, but there is no sheet 170. For example, it is possible to reduce the number of banknotes that are pushed out together by pushing out the sheet 170 to about 2 to 3 at the same time. ing.

  The stacked banknotes are transported after the uppermost banknote P is separated by the feed roller 119 and the blocking roller 120, and the remaining banknotes are reversed with the feed roller 119, the kick roller 118, and the sub kick roller 117 reversed. It is rotated and returned to the thousand-yen banknote storage 110.

  Here, the kick roller 118 having a function of mainly paying out the banknote P in the creeping direction thereof has a conveying portion having a sliding contact surface for kicking out the banknote P in contact with the banknote P in the circumferential direction, and the banknote P. Has a non-conveying part which does not contact. The conveying portion is provided with a high friction member 171 in a part of the circumferential direction, and the non-conveying portion where the high friction member 171 is not provided is configured so that the surface of the arc portion of the outer periphery is a sliding surface of the high friction member 171. It is formed inside the circle 172 including it. That is, the outer peripheral surface of the non-conveying portion gradually decreases in radius from the joint portion with the clockwise end portion of the transport portion, and immediately before the joint portion with the counterclockwise end portion of the transport portion. The shape is formed so as to return to the radius of the conveyance unit, and the conveyance unit and the non-conveyance unit are formed asymmetrically.

  In the thousand-yen banknote storage 110 configured as described above, during the dispensing operation, first, the pusher unit operates, and the suspension plate 153 of the operation frame 151 lifts the inner frame 146. As a result, the banknotes P placed on the stage 160 rise while being sandwiched between the rails 149, but the uppermost banknote P is the sub kick roller 117 and kick roller 118 of the banknote feeding section. , The rail 149 moves up away from the bill P while leaving the bill P and the stage 160 in that position, and the inner frame 146 stops when it reaches its top dead center.

  At this time, the bill P is in a state of being pressed against the sub kick roller 117 and the kick roller 118 by the urging means including the torsion spring 166, the tension spring 168, and the leaf spring 169. When the number of banknotes placed on the stage 160 is large, the back side of the stage 160 is lowered because the shafts 164 of the links 162 and 163 are slightly offset toward the banknote entrance / exit side. Is prevented from being pressed against anything other than the sub kick roller 117 and the kick roller 118, so that a plurality of banknotes are not paid out at the time of withdrawal. Further, the pusher unit operates, and the suspension plate 153 of the operation frame 151 lifts the inner frame 146. At the same time, the sheet 170 rises so as to block the feeding direction of the bills P as shown in FIG. . In addition, by raising the inner frame 146, the height of the withdrawal reject box 111 formed between the bottom of the outer frame 147 is raised, and the frontage for receiving the reject banknote is enlarged.

  Next, when the sub kick roller 117, the kick roller 118, and the feed roller 119 (only the kick roller 118 is shown in FIG. 9) of the bill feeding portion are rotated in the clockwise direction in the drawing, the sub kick roller 117 is rotated. The high friction member 171 provided in a part of the circumferential direction of the kick roller 118 kicks out the uppermost banknote P in the creeping direction by frictional contact. At this time, due to the friction between the banknotes, a plurality of banknotes are going to be fed together with the uppermost banknote P. However, the sheet 170 located at the exit is obstructing, so the sheet 170 is pushed out. The banknote to go is suppressed to about 2 or less at most.

  When the leading end of the banknote P in the feeding direction is applied to the entrainment area between the feed roller 119 and the blocking roller 120, the uppermost banknote P is fed out by the feed roller 119 and the inter-banknote friction with the uppermost banknote P is reached. The accompanying banknotes are prevented from being fed multiple times by the blocking roller 120. The bills P fed out by the feed roller 119 are then pulled out by a pair of pulling rollers (not shown) and conveyed to the withdrawal bill discriminating unit 121.

  The banknotes that have passed through the withdrawal banknote discrimination unit 121 are transported to the withdrawal reservation unit 112 or the withdrawal reject box 111 according to the discrimination result. As a result of the discrimination in the withdrawal bill discriminating unit 121, the bills that should not be withdrawn are smoothly carried into the withdrawal reject warehouse 111 having a wide opening, and further, at the entrance of the withdrawal rejection warehouse 111. Pushed by the directed impeller 125. The banknotes pushed in this way are stacked and stored in the withdrawal reject box 111.

  After the bills are fed out from the thousand-yen bill storage 110, the remaining separated bills remain between the thousand-yen bill storage 110, the feed roller 119, and the blocking roller 120. Since these bills are an obstacle when the deposited bill is stored in the thousand-yen bill storage 110, it is necessary to return it to the thousand-yen bill storage 110. As shown in FIG. 10, after the uppermost banknote P is pulled out from the feed roller 119 and the blocking roller 120 by a pair of pulling rollers, the sub kick roller 117, the kick roller 118, and the feed roller 119 (FIG. 10). Then, only the kick roller 118 is shown.) Is rotated counterclockwise in the drawing, and the separated remaining banknotes are returned to the thousand-yen banknote storage 110.

  The kick roller 118 is not in contact with the high friction member 171 when the tip of the banknote P in the feeding direction is conveyed to the entrainment region between the feed roller 119 and the blocking roller 120, and the high friction member 171 is provided. The surface of the non-conveying portion that is not placed is opposed to the banknote and is stopped in a state of being separated from the banknote. Therefore, when the kick roller 118 is rotated counterclockwise in the drawing in order to return the remaining separated banknote, the banknote is pressed at the boundary between the transport section and the non-transport section, and then the transport section The high friction member 171 pushes in at a stretch.

Next, biasing means including the torsion spring 166, the tension spring 168, and the leaf spring 169 will be described with reference to FIG.
The banknote needs to have a force sufficient to be properly pressed against the kick roller 118 in the payout operation when dispensing. This force increases as the number of banknotes stored increases, and the weight of the banknotes is added downward.This compensates for this, and the accumulated value of the space existing between the banknotes with folds and creases also increases. Extra power to crush is required. In consideration of these, the pressing force of the urging means with respect to the number of stacked banknotes needs to change such as an ideal curve 181 indicated by a thick solid line in the drawing.

  On the other hand, in the conventional urging means constituted by a torsion spring and a leaf spring, as shown in FIG. 11A, the pressing force characteristic 182 by the urging means has a small number of stacked banknotes. It is set so as to always be stronger than the ideal curve 181 from the time to the time when it is large. The reason why the pressing force characteristic 182 has a width in the vertical direction in the drawing is that the torsion spring and the leaf spring have hysteresis. As described above, when the characteristics of the torsion spring and the leaf spring are set in accordance with the maximum allowable number of stored sheets, the pressing force becomes too large in the area where the stored number of sheets is small, which causes a large number of rejected banknotes. It was.

  Therefore, in this embodiment, the tension spring 168 is added, and the characteristics of the biasing means including the torsion spring 166, the tension spring 168, and the plate spring 169 are biased as shown in FIG. The pressing force characteristic 183 by the means approaches the ideal curve 181. In this case, the tension spring 168 is optimized, including the torsion spring 166, not simply added. According to this characteristic, it is possible to realize a characteristic in which the pressing force does not increase transiently from an area where the number of stored sheets is small to an area where the number of stored sheets is large, only by the configuration of the spring. Thus, it becomes possible to secure the feeding performance in a space-saving manner.

Next, the configuration of the coin processing device will be described.

Represents a state. The pulley structure represents the structure of the pulleys 262 to 267 described above, but here, the structure around the pulley 262 will be described as a representative.

  As shown in FIG. 17A, the pulley 262 is rotatably supported around a shaft 271 having a predetermined length, and the shaft 271 is supported by a bearing member 272 fixed to the frame 240. .

  That is, a pair of bearing pads 273 whose sliding surfaces are surface-treated is fixed to one end side of the shaft 271, and a cylindrical pulley 262 is extrapolated therebetween. A locking ring 274 is fixed to the other end of the shaft 271, and this locking ring 274 is locked to an outer edge portion of an oval support hole 275 provided on the side wall of the bearing member 272. This prevents the pulley 262 from falling off. The width of the support hole 275 is substantially equal to the diameter of the shaft 271 and the length in the vertical direction is longer than that.

  The bearing member 272 is provided with a presser spring 276 that biases the shaft 271 downward, and a holder 277 that holds the presser spring 276 between the shaft 271 and a horizontal hole that passes through the holder 277. A shaft 271 is inserted through 278.

  As shown in FIG. 17B, while the coin M is being transported, the coin M is interposed between the transport belt 213 and the sliding surface 242, and therefore the pulley 262 is pushed up. At this time, the shaft 271 is pushed up against the force of the presser spring 276. However, since the support hole 275 is vertically long, the shaft 271 is inclined as indicated by an arrow in the drawing with the vicinity of the support hole 275 as a fulcrum. In this state, the pulley 262 rotates around the shaft 271 to guide the conveyance belt 213.

  In particular, as illustrated in FIG. 14, the coin M is transported while being displaced toward the back side and the near side of the coin processing device in the transport process by the lifter unit 202 due to the shape of the transport path 241 described above. That is, the coin M transferred to the conveyor belt 213 at the lower end of the conveyance path 241 is displaced to the back side at the position of the coin identification unit 203 and follows the side wall 243 on the near side before the coin identification unit 203. And is always guided at a fixed position along the side wall 243 on the near side at the position of the coin identifying unit 203. As a result, the coin identifying unit 203 can ensure the positional accuracy of the coin M at the time of authenticity determination or denomination identification, and can perform a highly accurate identification process. Further, when the coin M passes through the coin identifying unit 203, it is guided along the back side wall 243 and returns to the near side. As a result, since the distance in the depth direction when the coin M is delivered to the coin sorting unit 204 can be increased, the arrangement space for the detection sensor 223 and the like can be afforded, and the coin processing apparatus can be made compact in the depth direction. be able to.

  Returning to FIG. 12, in the coin processing device configured as described above, when a denomination coin in the coin insertion slot 201 is inserted, the coin is drawn by the roller 208 and transferred to the lifter unit 202. The lifter unit 202 conveys the transferred coins upward. In the middle of the conveyance, the coin is identified by the coin identification unit 203. If it is a genuine coin, the reject gate 215 is retracted from the conveyance passage and is conveyed as it is to the coin sorting unit 204, and if it is a fake coin, it is captured by the reject gate 215. It is dropped onto the conveyor belt 229 via the reject chute 217 and returned to the coin payout exit 206.

  On the other hand, the coins transported to the coin sorting unit 204 are sandwiched between the sliding surface of the transport passage and the transport belt 220 and are transported to the back side of the coin processing apparatus in an upright state. Before the coin reaches the sorting gate 219 corresponding to the denomination determined by the coin identifying unit 203, the sorting gate 219 corresponding to the denomination slides to block the conveyance path. As a result, the coin falls from the sorting gate 219 into the corresponding denomination change tube of the coin storage unit 205 and is stored in the change tube in a stacked state in the coin thickness direction. In addition, in the coin storage unit 205, when the corresponding denomination change tube is full, the sorting gate 219 does not operate, and the coin is transported to the back of the coin processing device and stored in the overflow storage in a denomination mixed state. To do.

  When change is necessary, the solenoid 228 corresponding to the required denomination of the payout mechanism unit operates to pay out the required number of coins from the corresponding change tube of the coin storage unit 205. The paid out coins fall on the transport belt 229, are transported on the transport belt 229, and are withdrawn from the coin payout exit 206. When coins paid out from the change tube fall on the conveyor belt 229, the coil sensor 231 provided for each denomination on the lower surface of the conveyor belt 229 detects the coin, and the necessary money is supplied to the conveyor belt 229 from the dispensing mechanism. You can know that the coins of the seed have been paid out.

  As described above, in the coin processing device of the present embodiment, the lifter unit 202, the coin sorting unit 204, and the output unit that serve as a coin conveyance path are provided so as to surround a plurality of change tubes arranged in parallel in the depth direction. Since the gold coin transport unit 207 is disposed and the coin identifying unit 203 is provided in the middle of the lifter unit 202 having a sufficient space, the entire apparatus can be configured compactly.

  In the above-described embodiment, the roller 208 is shown as the conveying unit that draws the coin inserted into the coin insertion slot 201 and delivers it to the lifter unit 202. However, the roller 208 may be configured as a conveying belt or other conveying unit. However, from the viewpoint of making the apparatus compact, it is preferable to employ a small conveying means such as a roller.

  As described above, as an embodiment of the present invention, the money processing device mounted on the oil pump installed in the self-service type gas station has been described as an example. Here, the banknote processing device and the coin processing device that can be reduced in size are described. The configuration can be similarly applied to other money processing apparatuses that are required to be downsized.
