Description:
FIELD OF THE INVENTION 
     This invention relates to a coin processor to process a plural kinds of loose coins of various money types. Especially, this invention concerns a coin processor which is built in a vending machine and processes the coin thrown therein into an exchange coin. This invention also concerns a coin processor to prepare exchange money, by processing plural types of coins thrown into the vending machine, of the money type. The term “coin” in this specification includes currency. The term “coin” can also refer to pseudo-coins such as medals, tokens and so on. Further, the term “vending machine” in this specification of course includes the medal or token vending machine. Also, the term “vending machine” refers to devices for the exchange of coins or currency including machines of the game machine type. 
     BACKGROUND OF THE INVENTION 
     A comparatively small coin hopper device is disclosed in Japanese Patent Application 10-254512 by this applicant. 
     FIG. 9 is an outlined perspective view of the coin hopper device with an escalator disclosed in Japanese Patent Application 10-254512. This hopper device H stores a lot of coins (not shown in the figure) in hopper tank T, of a funnel shape and discharges the coins above one by one. Electric motor device E with gear train is installed under base board B diagonally arranged. Disk D at the bottom in hopper tank T is rotated with the electric motor device E. A penetration hole (not shown) of this disk D is rotated, the coin is pushed out along base board B and is then discharged out from hopper tank T. The coin pushed out from hopper device H is transported above with escalator device C. The escalator device C has a passage P for coins providing communications to the base plate B. Frame F is provided for reinforcing the long escalator C. 
     This hopper device H, electric motor device E with the gear train was set up under base board B, and hopper tank T was set up on base board B. Therefore, hopper device H had a problem which enlarged in the vertical direction as shown in FIG.  4 . To miniaturize the hopper device, for instance, the base board B is made horizontal, and the electric motor device E and the gear train are sideways arranged under the base board B. However, there was a limit in the miniaturization of coin hopper device with the above-mentioned arrangement. 
     When vending machines are used and the amount of money deposited in the machine is more than the price of commodity, the difference is automatically disbursed as change (exchange money). In addition, when the coin inserted into vending machine is a pseudo coin such as foreign country coin and so on, this coin is automatically returned or canceled. The coin inserted into the vending machine is recycled for exchange money by the coin processor built therein. Coins for exchange money are prepared beforehand in the vending machine and when the exchange coins are insufficient, the coin inserted is reused for exchange money. 
     A coin processor for a vending machine is discussed in Japanese Patent Application 8-214917 or Patent Disclosure 9-265561 by this applicant. As for this coin processor, a plurality of hopper devices to store a lot of coins of same money kind in lose state are vertically piled up. And, on the top part of hopper devices vertically piled up, a coin selector is provided. As for the coin inserted into the vending machine, the money kind is distinguished with the selector, and then existing the passage, the coin is stored in the hopper device of same money kind. When the exchange coin is necessary, each hopper device is operated by an electric signal and the desired exchange coin is disbursed automatically. 
     In the coin processor for above-mentioned prior vending machine, there was a problem that a-pseudo-coin which is similar to the actual coin is not rejected with the selector and is stored in the hopper device. That is, there was a problem that another true coin was disbursed from the hopper device, when a pseudo-coin was stored in the hopper device and the return button was pushed. The coin processor for prior vending machine exchanged a pseudo-coin for a true coin. On the other hand, there was another problem that a true coin was rejected when the accuracy of coin selector was raised.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to the drawings in particular, an example of the invention is shown in FIGS. 1-3. The device of the invention includes an almost rectangular bottom board  11 . This bottom board  11  with this complex shape is a resin molded product. Electric connector  12  is fixed on one end part of rectangular bottom board  11  by means of screws  13 . On the other end part of bottom board  11 , electric motor  15  is extends up and is fixed with screws  13 . Electric motor  15  with column shape is fixed in a head standing condition. A small gear  16  is fitted on the projected turning shaft which is located under electric motor  15 . A gear  17  at the above left in FIG. 3 is rotatably mounted on the pivot standing up on bottom board  11 , adjacent to slider  19 . Middle gear  17  engages with small gear  16 . Moreover, small gear  21  is integrally formed on the upper surface of middle gear  17 . Gear  22  at the left center in FIG. 3 is also rotatably mounted on the pivot which extends up from bottom board  11 , adjacent to slider  19 . Middle gear  22  engages with small gear  21  (see FIG.  2 ). Small gear  23  is integrally formed under middle gear  22 . Large gear  25  at the lower left in FIG. 3 has a central part penetrated through by rotation axis  26  at the center thereof. The lower part of this rotation axis  26  is rotatably inserted into bottom board  11 , adjacent to slider  19 . Large gear  25  engages with small gear  23  (see to FIG.  2 ). 
     At the above center in FIG. 3 wiring  10  for the electric motor  15  is shown. FIG. 3 also shows an electric connector  9  for a sensor. 
     FIG. 2 shows the assembled state of the device of the embodiment of FIGS. 1-3. FIG. 1 shows the further almost rectangular base board  31  on the assembled state of the device of FIG.  2 . This further shows the arranged round disk  41  thereon. 
     The base board  31  consists of a resin molded product. Large metallic plate  33 , which almost becomes a circle, is fixed on the center thereof On the point part of base board  31 , ring  35  which freely penetrates through electric motor  15  is formed. Details are omitted from the drawing, but between disk  41  and ring  35 , guide splinter  36  for coins is fixed on plate  33 . Moreover, exit  37  for coins is formed near ring  35  of base board  31 . Some details were omitted, but at each side of coin exit  37 , rollers  39  are pivoted respectively. A showing of the other rollers has been omitted. Each roller  39  is moveably mounted respectively with a spring (not shown). Also, near one of rollers  39 , a couple of pins  32  for guiding coins are provided to rise and fall freely with a spring board (not shown). As for the other pins, these have not been shown to preserve clarity in the drawing. 
     Disk  41  has a circle shape. Penetration holes  42  for holding coins flat are opened in the direction of surrounding and at equal intervals. Two or more small long and slender nails  43  are provided to push the coin out. These nails  43  project under the disk  41 . As shown in FIG. 1, big hopper  45  for coin storage having a flat rectangular funnel shape is further installed thereon. Hopper  45  shows only the size in chain lines, but it is a resin molded product. A corner part of hopper  45  is formed to store the upper part of electric motor  15 . Moreover, the hooks (not shown) formed on the under edge of hopper  45  are inserted into small holes  47  on base board  31 . A couple of nails  49  formed on base board  31  dig into hollows (not shown) formed on hopper  45 , existing springs (not shown), and the hopper  45  is fixed thereon. Further, near coin exit  37 , sensor  8  for coin calculation which has a F shape is installed. 
     As for this execution example with the above mentioned configuration, when electric motor  15  is turned, small gear  16  is rotated. When small gear  16  is rotated, middle gear  17  and small gear  21  are rotated. When small gear  21  is rotated, middle gear  22  and small gear  23  are rotated (refer to FIG.  2 ). When small gear  23  is rotated, large gear  25  is rotated (see FIG.  2 ). When large gear  25  is rotated, disk  41  is rotated in the direction of the arrow, existing rotation axis  26  (see FIG.  1 ). 
     As a result of the rotation of disk  41 , a plurality of coins in flat rectangular funnel-shaped hopper  45  will be one by one disbursed to exit  37  by means of disk  41 . When electric motor  15  is turned, the coins fall into either of penetration holes  42  of rotated disk  41 . The lowest coins which fall in penetration holes  42  slide on the upper surface of metal plate  33 , by rotation of disk  41  and existing nails  43 . The coin which slides on the upper surface of plate  33  with nail  43  is guided toward the exit  37 , existing inner wall of hopper  45  and guide splinter  36 . The coin guided toward the exit is pushed out from the position of penetration hole  42  to the outside, by means of nail  43  and a couple of pins  32 . The coin pushed out is further pushed out outside by nail  43 , resisting the springs of a couple of rollers  39  (refer to arrows of FIG.  1 ). 
     According to this invention as described above, only by changing the arrangement of composition, a big effect is achieved that the coin hopper device can be miniaturized. That is, according to this invention, there is a big effect in which the height of hopper device can be greatly lowered, by arranging an electric motor at hand-standing and arranging a gear train for deceleration flatly and horizontally. 
     The device of FIG. 4 has a first hopper device  111  at lower side thereof, which has an almost horizontal box shape. And, a similar second hopper device  112  is arranged thereon. On the second hopper device  112 , a similar third hopper device  113  is arranged. A similar fourth hopper device  114  is arranged on that further. In addition, on this fourth hopper device  114 , there is arranged a similar flat-box-shaped hopper device  115 . And, on the hopper device  115 , there is arranged a coin selector  116  which has a upright box shape. 
     The selector  116  distinguishes electronically the coin which was inserted into vending machine (not shown in the drawing). That is, the coin thrown into or deposited in the vending machine is guided by using natural fall and thrown in a slot  117  of selector  116 . The coin which is thrown in slot  117  and falls naturally is distinguished the money kind thereof electronically. As for the coin which falls naturally, the diameter, the thickness, and the material are distinguished for instance with three pairs of magnetic sensors (not shown) and the money kind thereof is determoned. 
     The coin, of which the money kind is determined, is guided with the solenoid (not shown) etc., falls naturally in hopper  125  of hopper device  115 , and is stored. The pseudo coin such as a foreign coin of which the money kind is not determined is rejected or returned, using natural fall and being guided by passage  118 . 
     In FIG. 5, there is shown the hopper device  115 , of which hopper  125  with rectangular tube shape is removed. Hopper device  115  has an electric motor  135 , of which the projection end of turning shaft (not shown) is located downward. On the lower end of turning shaft of electric motor  135 , a first gear (not shown) is fixed. On the other hand, at the bottom position of hopper  125  in which coins are stored, disk  145  is provided (see FIG.  5 ). This round disk  145  discharges coins one by one. On the lower end of rotation axis  155  of disk  145 , a second gear (not shown) is fixed. There is provided a gear train (not shown) for connecting the second gear and the first gear (see embodiment of FIGS.  1 - 3 ). The first gear, the second gear and the gear train are located within a case  165  for flat driving device. This case  165  is constituted by a rectangular bottom board and a base board which becomes a lid. Moreover, the case  165  is a resin molded product and, at the center of upper surface thereof, a metallic big plate  175  with almost circular shape is fixed. Between disk  145  and electric motor  135 , a coin guide splinter (not shown) is fixed. Moreover, at the coin discharge entrance near the electric motor  135 , a sensor  195  for coin detection is arranged. Sensor  195  includes a magnetic sensor for instance and detects the money kind of the coin by the diameter etc. of the discharged coin. On both sides of sensor  195 , a roller (not shown) is pivoted, respectively. Each roller is freely moved with a spring (not shown), respectively. Near the one roller, a couple of pins for coin guide (not show) are provided to rise and fall in fee, existing spring board. Further, in the disk  145 , a penetration holes  5  for holding coins in a flat state are opened in surrounding direction and at equal intervals. At the under surface of disk  145 , a plurality of small slender nails or pins (protruding elements)  185  project for pushing coins. 
     Hopper  125  is a resin molded product and one corner part thereof is formed to store the upper side part of electric motor  135 . This hopper  125  is fixed on case  165 , for instance, nails or retention latches  105  being formed on case  165  and inserted into holes with a spring (not shown). When the electric motor  135  turns, as for hopper device  115 , disk  145  rotates in the arrow direction, with rotation of the gear train and rotation axis  155 . As a result, different money kinds of coins in hopper  125  will be disbursed one by one from discharge entrance near electric motor  135 , by disk  145 . When electric motor  135  is turns, the coin falls into either of penetration holes  5  of rotated disk  145 . The lowest coin falls into penetration holes  5  and slides on the upper surface of metal plate  175 , by rotation of disk  145  and existing nails  185 . The coin which slides on the upper surface of plate  175  is guided in the direction of sensor  195 , positioned along the inner wall of hopper  125  and by the guide splinter (not shown). The coin which was guided toward the sensor position  195  is pushed out, outside from the position of penetration hole  5 , by nail  185  and a couple of pins (not shown). The coin pushed out, outside, is further pushed out on sensor  195  and discharged, by nail  185  and resisting the spring of couple rollers (not shown). When the pushed out and discharged coin passes sensor  195 , the money kind thereof is judged electronic-engineeringly. 
     In FIG. 6, the most lowest hopper device  111  shown in FIG. 1 is shown. The hopper device  111  is similar to hopper device  115  of FIG.  2 . That is, disk  141  which discharges coins one by one, is set at the bottom position of hopper  121  for storing coins. Similarly, at the bottom of rotation axis  151  of disk  141 , a gear (not shown) is fixed (see embodiment of FIGS.  1 - 3 ). A plurality of gears (not shown) including this gear are set in flat case  161  for driving device. In a similar way, case  161  is a resin molded product and, at the center of upper surface thereof, there is fixed a metallic and big plate  171  which has an almost circular configuration. Moreover, at the coin discharge entrance near electric motor  131 , a sensor  191  for coin detection is arranged (see the lower part of FIG.  4 ). 
     The sensor  191  is formed of a magnetic sensor for instance and detects the discharged coin. Therefore, sensor  191  concerned is used for the calculation of the discharged coin. In the same way, on both sides of sensor  191 , a roller (not shown) is pivoted respectively. Moreover with a spring (not shown), each roller can be moved freely, respectively. Similarly, near the one roller, a couple of pins (not shown) for coin guiding are provided to rise and fall in free, existing spring board. Also, in disk  141 , penetration holes  101  for holding the coin flat are opened in surrounding direction and at equal intervals. In the same way, on the under surface of disk  141 , a plurality of small slender nails (not shown) to push coin out project. Hopper  121  is also a resin molded product and one comer part thereof is formed to store the upper side part of electric motor  31 . At the round edge part of hopper  121 , for instance, at the round edge part opposing to the electric motor  131 , a notch N 1  is formed. This notch N 1  is opened and shut by guide board G 1  with roof shape. The bottom part of guide board G 1  is bent under hopper device  111 , that is, under case  61 . Under case  161 , a solenoid S 1  with plank shape is arranged. By this solenoid S 1 , guide board G 1  is shuttled horizontally. 
     As for the above-mentioned hopper device  111 , when electric motor  131  is turned, existing gear train (not shown) and rotation axis  151  and disk  141  are rotated along the arrow direction as well as the above-mentioned. As a result, the coins of same money kind in hopper  121  will be disbursed one by one from the discharge entrance near electric motor  131 , by rotation of disk  141 . That is, when electric motor  131  is turned, the coin falls in either of penetration holes  101  of rotated disk  141 . The lowest coin which has fallen in penetration hole  101  slides on the upper surface of metal plate  171 , by the rotation of disk  141  and the nail. The coin which slides on upper surface of plate  171  is guided toward the sensor  191 , along the inner wall of hopper  141  and by the guide splinter (not shown). The coin guided toward the sensor  191  is pushed out from the position of penetration hole  101 , by the nail and couple of pins (not shown). The coin pushed out, outside, is further pushed out on the sensor  191  and is discharged outside, by the nail and resisting the springs of couple of rollers (not shown). The coin which is pushed out and discharged is detected in an electronic-engineering manner, when the sensor  191  is passed. 
     The similar second hopper device  112  is arranged on the first hopper device  111 . The similar third hopper device  113  is arranged also on the second hopper device  112 . The similar fourth hopper device  114  is arranged further on the third hopper device  113 . Therefore, in FIG. 5, reference numerals have been described only as to the corresponding parts of these hopper device  111 - 114 . 
     With the configuration mentioned with reference to FIGS. 4-6, when the coin is thrown into the vending machine (not shown), the coin is guided and is inserted in slot  117  of selector  116 . The coin inserted in slot  117  is distinguished the money kind by the selector  116  in an electronic engineering manner. The coin of which the money kind is not distinguished is guided into passage  118  and rejected by natural failing (see FIG.  4 ). That is, the coin of which the money kind is not distinguished is canceled to the return entrance of vending machine (not shown). The coin of which the money kind is distinguished with selector  116  is stored in the hopper device  115  based on the operation of a solenoid (not shown). In other words, the coin of which the money kind is distinguished is reserved temporarily in the hopper device  115 . In this situation, when the return button of vending machine (not shown) is pushed, the electric motor  135  is driven and then the coin is discharged into passage  118 . That is, the coin reserved temporarily in hopper device  115  is canceled to the return entrance of vending machine. 
     Usually, when the coin of which the money kind is distinguished is reserved in the hopper device  115 , the commodity purchase button of vending machine (not shown) is pushed. The electric motor  135  is driven at this time and the coin is discharged in passage  118 . The coin discharged from the hopper device  115  passes the sensor  195  and falls naturally in the passage  118 . The money kind of the coin is judged when the coin passes sensor  195  and, for instance, solenoid S 1  is operated by this judgment signal. Guide board G 1  projects into passage  118  when solenoid S 1  is operated, and the falling coin will be taken into hopper device  111 . Therefore, when the return button of vending machine is pushed, it is preferable that electric motor  135  is driven at the high speed. Moreover, when the commodity purchase button of vending machine is pushed, it is preferable that electric motor  135  is driven in the low speed. For instance, the most upper hopper device  114  is used for e.g., 500 yen coins and the below hopper device  113  is used fore.g., 100 yen coins. And, the lowest hopper device  111  is used for e.g., ten yen coins and the above hopper device  112  is used for e.g., 50 yen coin. The yen coins represent an example only and various denominations of U.S. currency may also be provided for. It is of course good that the height of hopper  124  for the 500 yen coins (the coin with the largest diameter) is enlarged to have a big capacity. Matching to this, it is of course good that the height of hopper  122  for the 50 yen coin with the smallest diameter is reduced to have a small capacity. For instance, such as the above-mentioned, it is now assumed that 500 yen coins, which are thrown into the vending machine and of which the money kind is distinguished, is reserved in hopper device  115 . When the purchase button of the 300 yen commodity of the vending machine is pushed at this time, electric motor  135  is driven and a 500 yen coin is discharged into passage  118 . The 500 yen coin is discharged from the hopper device  115  passes sensor  195  and falls naturally in passage  18 . When the 500 yen coin passes sensor  195 , the money kind is judged and solenoid S 4  is operated by the 500 yen judgment signal. Guide board G 4  is projected into passage  118  when the solenoid S 4  is operated and the falling 500 yen coin is taken in hopper device  114 . On the other hand, the 300 yen commodity is disbursed from the vending machine by means of a signal processor such as CPU and so on, which are omitted from the drawings. 
     At the same time, an exchange money signal which means 500 yen minus 300 yen equals 200 yen is output to the electric motor (not shown) of the third hopper device  113 . When this electric motor is driven, one 100 yen coin is discharged from the hopper device  113  into passage  119 . One 100 yen coin discharged from the hopper device  113  passes the sensor (not shown) and falls naturally in passage  119 . This sensor detects one 100 yen coin and transmits the detection signal to the signal processor. One 100 yen coin discharged in passage  119  falls naturally and is disbursed to the return entrance of vending machine as exchange money. On the other hand, electric motor  133  is driven further and another 100 yen coin from the hopper device  113  is discharged into passage  119 . As well as the above-mentioned, the sensor detects another 100 yen coin and transmits the detection signal to the signal processor. This signal processor confirms the completion of exchange money of the 200 yen and stops the electric motor of the third hopper device  113 . Therefore, two 100 yen coins total will be disbursed to the return entrance of the vending machine as exchange money. Further, as not shown, it is of course that a solenoid and so on are provided at the lower side of passage  118 . For instance, when either of guide boards G 1 -G 4  is not operated, the purpose of the solenoid is to store the coin within the vending machine, preventing the coin from being returned. Moreover, the purpose of solenoid is to store the coin in the vending machine preventing the coin from being returned, when either of the hopper devices  111 - 114  is nearly full, for instance. 
     In FIG. 7, a hopper device  110  is shown in the outline. This is still another embodiment of the invention. Hopper device  110  is formed almost similarly to hopper device  115  in FIG.  4 . That is, hopper device  110  has arranged electric motor  130 , which locates the projection end of turning shaft downward. Electric motor  130  provides positive and reverse rotations. A first gear (not shown) is fixed on the lower end of turning shaft of electric motor  130 . Similarly, a disk  140  is prepared for at the bottom position of hopper  120  in which coins are stored. Also, with the disk  140 , positive and reverse rotations are possible. 
     This round disk  140  discharges coins one by one. A second gear (not shown) is fixed on the lower end of the rotation axis of disk  140 . A gear train (not shown) connects the second gear and the first gear. The first gear, the second gear, and the gear train are set in a flat case  160  for the driving device. This case  160  is composed of a rectangular bottom board and a base board which becomes a lid. Similarly, the case  160  is a resin molded product, and on the center of the upper surface thereof, a metallic big plate  170  which is nearly circular is fixed. 
     Discharge entrance  6  of coin is formed near electric motor  130  and further discharge entrance  7  for the coin is formed on the opposite side. Also, sensor  190  for coin detection is arranged at coin discharge entrance  7 . This sensor  190  consists of a magnetic sensor for instance and detects the money kind of coin by the diameter etc. of discharged coin. Rollers (not shown) are pivoted at both side of each of coin discharge entrances  6  and  7  respectively. Four rollers in total are arranged respectively. Moreover, each roller thereof moves freely via a spring (not shown) respectively. Also, near each of the another rollers, a couple of pins to guide the coin (not show) are provided to freely rise and fall with a spring board, respectively. In other words, four guide pins which become two pairs in total are provided. 
     The disk  140  has penetration holes for holding coins flat. These holes are opened in a surrounding direction and at equal intervals. Under disk  140 , two or more nails project (not shown) to push the coin out. Similarly, hopper  120  is a resin molded product and is formed to store the upper side part of electric motor  130  in the corner part thereof. For instance, the nails similarly formed on case  160  cut into holes of hopper  120 , existing spring (not shown), and the hopper  120  is fixed. As for above-mentioned hopper device  110 , when electric motor  130  is reversely turned, existing the gear train (not shown) and rotation axis, disk  140  is rotated counterclockwise. As a result, by means of disk  140 , the coins in hopper  120  will be disbursed one by one from discharge entrance  6  near electric motor  130 . That is, when electric motor  130  is reversely turned, the coin falls into either of penetration holes of rotated disk  140 . By further rotation of disk  140 , the lowest coin which has fallen in penetration hole slides on the upper surface of metal plate  170  and the nail. The coin which slides on upper surface of plate  170  is guided toward the discharge entrance  6 , along the inner wall of hopper  120  and by the guide splinter (not shown). 
     The coin guided toward discharge entrance  6  is pushed out outside from the position of penetration hole, by the nail and a couple of pins (not shown). The coin pushed out, outside, is further pushed out to discharge entrance  6  by the nail and discharged outside, resisting the spring of a couple of rollers (not shown). Similarly, when electric motor  130  is positively turned, disk  140  is rotated clockwise. As a result, the coins of various money kinds in hopper  120  will be disbursed one by one from the other discharge entrance  7  by means of disk  140 . That is, when electric motor  130  is positively turned, the coins fall into either of penetration holes of rotated disk  140 . The most bottom coin falls in the penetration hole and slides on the upper surface of metric plate  170 , by the rotation of disk  140  and existing the nail. In the same way, the coin guided toward the discharge entrance is pushed out from the position of penetration hole, by the nail and a couple of pins (not shown). The coin pushed out is further pushed out to the discharge entrance  7  by the nail, and discharged resisting the spring of a couple of rollers (not shown). The coin which is pushed out and discharged is judged the money kind thereof electronically, when the sensor  190  is passed. 
     The embodiment shown in FIG. 7 has the above-mentioned composition and is operated almost similar to the embodiment of FIG.  4 . When the coin is thrown into the vending machine (not shown), the coin is inserted in the slot  117  of selector  116 . For the coin inserted in slot  117 , the money kind thereof is distinguished with the selector  116 . The coin of which the money kind is not distinguished is guided in passage  119  and rejected by natural fall. That is, the coin of which the money kind is not distinguished is canceled at the return entrance of vending machine (not shown). As for the coin of which the money kind is distinguished with selector  1116 , it is stored in hopper device  110 , properly based on the operation of solenoid (not shown). In other words, the coin of which money kind is judged is reserved temporarily in hopper device  110 . In this state and when the return button of vending machine (not shown) is pushed, electric motor  130  is reversely turned and the coin is discharged in passage  119 . The coin reserved temporarily in hopper device  10  is canceled at the return entrance of vending machine. When the coin of which money kind is known is reserved in hopper device  110 , the commodity purchase button of vending machine (not shown) is pushed. At this time, electric motor  135  is positively turned and the said coin is discharged in passage  118 . The coin discharged from hopper device  110  passes sensor  190  and falls naturally in passage  118 . When the coin passes sensor  190 , the money kind of the coin is judged and, for instance, solenoid S 1  is operated by this judgment signal. The explanation and drawing were omitted, but four hopper devices and solenoids S 1 -S 4  are piled up under hopper device  110  as well as is shown in FIG.  1 . When solenoid S 1  is operated, guide board G 1  is projected in passage  118  and the said falling coin will be taken into hopper device  111 . For instance, the most upper hopper device  114  is used for e.g., 500 yen coins as well as FIG.  4  and the hopper device  113  below is used for e.g., 100 yen coins. The lowest hopper device  11  is used for 10 yen coins and the hopper device  112  above is used for 50 yen coins. Thus, 500 yen coins which are thrown into the vending machine and the money kind thereof is judged and reserved in hopper device  110 . And, when the purchase button of 300 yen commodity offending machine is pushed, electric motor  130  is positively turned and the 500 yen coin is discharged in passage  118 . The 500 yen coin discharged from the hopper device  110  passes sensor  190  and falls naturally in passage  118 . When the 500 yen coin passes sensor  190 , the money kind thereof is judged, and solenoid S 4  is operated by the 500 yen judgment signal. When solenoid S 4  is operated, guide board G 4  is projected into passage  118 , and the falling 500 yen coin is taken into hopper device  14 . On the other hand, the 300 yen commodity is disbursed from the vending machine by means of the signal processor such as CPU. At the same time, the exchange coin signal which means 500 yen minus 300 yen equals 200 yen is outputted to electric motor (not show) of hopper device  113 . When this electric motor is driven, one 100 yen coin is discharged from the hopper device  113  to passage  119 . One 100 yen coin discharged from the hopper device  113  passes the sensor (not shown) and falls naturally in passage  119 . This sensor detects one 100 yen coin and transmits the detection signal to the signal processor. One 100 yen coin discharged in passage  119  falls naturally and is disbursed to the return entrance of vending machine as exchange money. On the other hand, the said electric motor is driven further and another 100 yen coin from the hopper device  113  is discharged in passage  119 . As well as the above-mentioned, the said sensor detects the 100 yen coin of another piece and transmits the detection signal to the signal processor. This signal processor confirms the completion of exchange money of said 200 yen and stops the electric motor of third hopper device  113 . Therefore, as exchange money, two 100 yen coins of total will be disbursed at the return entrance of vending machine. 
     A coin processor, which is the fourth example, is shown in FIG. 8 in the outline. The most top hopper device V 10  is about the same as hopper device  110  of FIG.  7 . The bottom position of tank V 1  where coins are stored has a disk V 2 . This disk V 2  can make positive and reverse rotations. Moreover, the discharge entrance V 6  for cancellation is formed, and discharge entrance V 7  for coin acceptance is formed on the opposite side. Sensor V 9  for money kind detection is arranged at coin discharge entrance V 7 . When an electric motor (not shown) is reversely rotated, as for the hopper device V 10 , disk V 2  is rotated counterclockwise, existing gears etc. As a result, the coin in tank V 1  will be disbursed one by one from discharge entrance V 6  by means of disk V 2 . Similarly, when electric motor is positively rotated, disk V 2  is rotated clockwise. As a result, the coin in tank V 1  will be disbursed one by one from the other discharge entrance V 7  by means of disk V 2 . The money kind of disbursed coin C 5  is judged electronically upon passing the sensor V 9 . The embodiment in FIG. 8 operates in a manner similar to that described for the embodiment of FIG.  7 . 
     When coin C 1  is deposited into the vending machine (not shown), the coin is inserted in the slot  117  of selector  116 . As for coin C 2  inserted in slot  117 , the money kind thereof is distinguished with selector  116 . Still, the coin (not shown) of which money kind is not distinguished is guided into passage  119  to be canceled. Coin C 2  of which the money kind is distinguished with selector  116  is stored in hopper device V 10 . In another way, coin C 3  of which the money kind is known is reserved temporarily in hopper device V 10 . When the return button (not shown) is pushed at this state, disk V 2  is reversely rotated. Therefore, the coin in tank V 1  is discharged into cancellation passage  119 . At the above-mentioned time, that is, when coin C 3  of which the money kind is known is reserved in hopper device V 1 , the commodity purchase button (not shown) is pushed. At this time, disk V 2  is positively rotated and coin C 3  is discharged into passage  118  for coin processing. Coin C 5  discharged from hopper device V 10  passes sensor V 9  and falls naturally in passage  118 . When coin C 5  passes sensor V 9 , the money kind thereof is judged and the judgment signal is sent. By this judgment signal, for instance, solenoid VS 4  of rotation type (described later) is operated. Four hopper devices V 11 -V 14  are piled up under hopper device V 10  in a manner as in the embodiment of FIG.  7 . Each solenoid VS 1 -VS 4  is built in each hopper device V 11 -V 14  respectively. For instance, when solenoid VS 4  is operated, guide board VG 4  is rotated into passage  118 . In this case, falling coin C 5  is taken into hopper device V 14 , by means of guide board VG 4  in passage  118 . For explanation in FIG. 8, the most upper hopper device V 14  is used for a large coin e.g., 500 yen coin. The hopper device V 13  below is used for e.g., a 100 yen coin. Thus, one 500 yen coin, which is thrown into the vending machine and of which money kind is known, is reserved in hopper device V 10 . And, when the purchase button of 300 yen commodity of vending machine is pushed, disk V 2  is positively rotated and the 500 yen coin is discharged in passage  118 . The 500 yen coin C 5  discharged from hopper device V 10  passes sensor V 9  and falls naturally in passage  118 . When the 500 yen coin passes sensor V 9 , the money kind thereof is judged and solenoid VS 4  is operated by the 500 yen signal. When solenoid VS 4  is operated, the guide board VG 4  is rotated in the passage  118 . Thus, the falling 500 yen coin C 5  is taken into hopper device V 14 . On the other hand, 300 yen commodity is disbursed from the vending machine by means of the signal processor such as CPU. At the same time, exchange money signal which means 500 yen minus 300 yen equal 200 yen is outputted to electric motor (not show). When this electric motor is driven, one 100 yen coin is discharged from hopper device V 13  into passage  119 . One discharged 100 yen coin passes the sensor V 9  of hopper device V 13  and falls naturally in passage  119 . This sensor V 9  detects one 100 yen coin and transmits the detection signal to the signal processor. One 100 yen coin discharged in passage  119  falls naturally and is disbursed at the return entrance of vending machine as exchange money. On the other hand, the electric motor is driven further, and another 100 yen coin is discharged from hopper device V 13  into passage  119 . As well as the above-mentioned, the sensor V 9  detects another 100 yen coin and transmits the detection signal to the signal processor. This signal processor confirms the completion of exchange money of the 200 yen and stops the electric motor of third hopper device  143 . As a result, two 100 yen coin of total will be disbursed at the return entrance of vending machine as exchange money. 
     As mentioned above, according to this invention, the coin thrown into the vending machine is temporarily reserved, and it is effective that the thrown-into coin can be returned as it is, by adding the simple composition. That is, this invention has the effect that there is no exchange of a pseudo coin for a true coin. The escrow function is added to the coin processor for vending machine. In other words, this invention has the effect that thrown-into coin is temporarily reserved, and the said coin can be received into the vending machine only when the commodity purchase button is pushed. 
     While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
