Description:
BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a coin distributing device, which is a component of a coin mechanism mounted onto a vending machine or the like, and which distributes coins inserted by coin type.  
           [0003]    2. Description of the Prior Art  
           [0004]    As a device for handling a coin inserted at the time of purchasing a commodity from a vending machine, there is mounted a coin mechanism, and the coin mechanism is provided with a coin distributing device for distributing coins by coin type. Each distributing unit of this coin distributing device is used to distribute coins inserted among counterfeit coins, 50 yen coins, 10 yen coins, 100 yen coins, and 500 yen coins, and specie is received in various coin tubes or a coin box while counterfeit coins are returned to a change outlet. Also, for various coin tubes, there are provided five coin tubes, four tubes of which automatically receive 50 yen coins, 10 yen coins, 100 yen coins and 500 yen coins respectively which have been inserted through a coin insert, and these coins are also used as coins for automatically making change. On the other hand, the remaining one tube is provided as a sub-coin tube, is replenished with 10 yen coins or 100 yen coins in advance, whose change depletion is expected, and the coins which are received in the sub-coin tube are to be used only for making change.  
           [0005]    In the above-described prior art coin distributing device, however, since when the sub-coin tube is utilized, an operator must replenish the sub-coin tube with coins by handwork, it is a troublesome operation and the coin distributing device has actually hardly been utilized.  
           [0006]    In addition, since the minimum amount of change to be automatically replenished with is 10 yen as described above, commodity prices to be set in the vending machine are set in increments of 10 yen, and the degree of freedom for setting the prices has become small.  
         SUMMARY OF THE INVENTION  
         [0007]    The present invention has been achieved in views of the above-described conventional problem, and is aimed to provide a coin distributing device in which five coin tubes are individually replenished with five types of coins automatically, these coins automatically replenished can be used as change, and the degree of freedom for setting commodity prices can be increased.  
           [0008]    According to a first invention, there is provided a coin distributing device having: a coin identifying unit for identifying types of coins inserted; and a plurality of distributing units for distributing coins identified by the coin identifying unit to each destination, in which, of coins distributed by the distributing units, specie is conducted to various coin tubes or a coin box passage while counterfeit coins are returned to the change outlet, wherein the structure is arranged such that the coin distributing device has five coin tubes so as to correspond to five coin types, and that each distributing unit contributes coins to five coin tubes by coin type.  
           [0009]    According to the first invention, since five coin types, for example, 500 yen, 100 yen, 50 yen, 10 yen and 5 yen coins can be received correspondingly to five coin tubes, it is possible to set commodity prices finely.  
           [0010]    According to a second invention, there is provided a coin distributing device according to the first invention, wherein the plurality of distributing units have; a first distributing unit for distributing to specie and counterfeit coins; a second distributing unit for distributing specie coins obtained by distributing by the first distributing unit to one coin type group and the other coin type group; a third distributing unit for distributing coins distributed to one coin type group by the second distributing unit to a passage leading to a coin tube in which first coin type coins are received, or a passage leading to each coin tube in which second and third coin type of coins are received; a fourth distributing unit for distributing coins distributed to the other coin type group by the second distributing unit to the coin box passage or a passage leading to each coin tube in which fourth and fifth coin type of coins are received; a fifth distributing unit for distributing coins obtained by distributing by the fourth distributing unit to a passage leading to a coin tube in which fourth coin type of coins are received, or a passage leading to a coin tube in which fifth coin type of coins are received; and a sixth distributing unit for distributing coins obtained by distributing by the third distributing unit to a passage leading to a coin tube in which second coin type of coins are received, or a passage leading to a coin tube in which the third coin type of coins are received.  
           [0011]    By means of these first to sixth distributing units, specie coins inserted are distributed to the first coin type (for example, 500 yen), the second coin type (for example, 50 yen), the third coin type (for example, 10 yen), the fourth coin type (for example, 100 yen), and the fifth coin type (for example, 5 yen) respectively, and are received in each coin tube corresponding to each coin type.  
           [0012]    According to a third invention, there is provided a coin distributing device according to the second invention, wherein the structure is arranged such that the third distributing unit and the fourth distributing unit are driven by a common solenoid and the fifth distributing unit and the sixth distributing unit are likewise driven by an other common solenoid. According to this third invention, in order to drive the plurality of distributing units by the common solenoid, it is possible to drive a multiplicity of distributing units by means of a small number of driving sources.  
           [0013]    In this respect, since by setting the first coin type to 500 yen coin, and the fifth coin type to 5 yen coin, of coins which are generally in circulation, 500 yen, which is the maximum amount, and 5 yen, which is the second minimum amount, can be handled, the use of 500 yen coin can reduce the number of change, and an amount of the rightmost digit of the commodity price can be made into 5 yen through the use of five yen coin. Therefore, the degree of freedom for setting the price becomes large.  
           [0014]    The above-described object, any other objects, features and advantages of the present invention will become manifest by the following description and the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0020]    FIGS.  1  to  5 A and  5 B show a coin distributing device according to an embodiment of the present invention.  
         [0021]    First, with reference to FIGS. 1 and 2, the description will be made of schematic structure of a coin mechanism. The coin mechanism is mounted on, for example, an vending machine, and is composed of: a coin identifying unit  10  for identifying coins (for example, 5 yen coins, 10 yen coins, 50 yen coins, 100 yen coins and 500 yen coins which are Japanese current coins) inserted through a coin insert  1 ; a coin distributing device  20  for distributing coins obtained by identifying by the coin identifying unit  10 ; and a coin receiving unit  30  for receiving coins obtained by distributing by the coin distributing device  20 , for performing money transactions for purchased commodities.  
         [0022]    The coin identifying unit  10  transmits a signal having a predetermined frequency to a coin inserted, identifies on the basis of a change in its received frequency whether the coin inserted is specie or a counterfeit coin, and further when the coin inserted is found to be specie, identifies different types of the 5 yen coin, 10 yen coin, 50 yen coin, 100 yen coin and 500 yen coin.  
         [0023]    The coin distributing device  20  is composed of first to sixth distributing units  201  to  206 , and the first to sixth distributing units  201  to  206  are installed in order along a coin passage through which the coins inserted pass.  
         [0024]    The first distributing unit  201  distributes a coin inserted to a return passage or a second distributing unit  202  on the basis of specie judgment or counterfeit coin judgment of the coin inserted which has been identified by the coin identifying unit  10  as shown in FIGS. 1 and 2. The first distributing unit  201  has a rotating flapper  201   a,  and this rotating flapper  201   a  is adapted to rotate by a solenoid SC 1 . When the solenoid SC 1  is in a non-excited state (OFF)(when the coin inserted has been found to be a counterfeit coin), the coin inserted passes through at the front of the rotating flapper  201   a,  and passes through a return passage (not shown) to be returned to the change outlet. On the other hand, when the solenoid SC 1  is in an excited state (ON) (when the coin inserted has been found to be specie), the rotating flapper  201   a  rotates, and the coin inserted passes on the rear side of the rotating flapper  201   a,  and falls down toward the second distributing unit  202 .  
         [0025]    The second distributing unit  202  distributes, as shown also in FIGS. 3A and 3B, coins which have been found to be specie by the first distributing unit  201 , to 100 yen coins and 5 yen coins, and 10 yen coins, 50 yen coins and 500 yen coins, which are other than those 100 yen coins and 5 yen coins. The second distributing unit  202  has back-and-forth distributing pieces  202   a ,  202   b  which are bifurcated, and these are caused to make frequent appearances from a coin passage A by means of a solenoid SC 2 . When the solenoid SC 2  is in a non-excited state (OFF), the 10 yen coins, 50 yen coins and 500 yen coins are caused to roll to the distributing piece  202   b  at the rear for being conducted toward the third distributing unit  203  as shown in FIG. 3A. On the other hand, when in an excited state (ON), as shown in FIG. 3B, the second distributing unit  202  is drawn backward to thereby cause the 5 yen coins and 100 yen coins to fall down on the distributing piece  202   a  at the front for being conducted toward the fourth distributing unit  204 .  
         [0026]    The third distributing unit  203  has a function to distribute the 10 yen coins, 50 yen coins and 500 yen coins which have been distributed by the second distributing unit  202 . The third distributing unit  203  rotates its rotating flapper  203   a  by means of a solenoid SC 3 , and when the solenoid SC 3  is in an excited state (ON), the rotating flapper  203   a  is rotated to cause the 10 yen coins and 50 yen coins to fall down toward a sixth distributing unit  206  to be described later. On the other hand, when in a non-excited state (OFF), the 500 yen coins are introduced to the inside thereof for being conducted toward a coin tube CT 500  for 500 yen.  
         [0027]    The fourth distributing unit  204  has a function to distribute the 100 yen coins and 5 yen coins which have been obtained by distributing by the second distributing unit  202 . Also, the fourth distributing unit  204  shares a driving source for its rotating flapper  204   a  with the solenoid SC 3  for the third distributing unit  203 . When the solenoid SC 3  is in a non-excited state (OFF), the 5 yen coins and 100 yen coins are caused to roll to the surface side of the rotating flapper  204   a  for being caused to fall down toward the fifth distributing unit  205  to be described later. On the other hand, when the solenoid SC 3  is excited (ON), the rotating flapper  204   a  opens, they are conducted to a coin box passage B (rear side of the rotating flapper  204   a ) for being introduced into a coin box (not shown). In this respect, when any of various coin tubes CT 500 , CT 100 , CT 150 , CT 10  and CT 5  is full and corresponds to a coin, whose coins inserted are filled, it is arranged such that the second distributing unit  202  is excited to conduct it to the fourth distributing unit  204 , and further the fourth distributing unit  204  is rotated to thereby introduce it into the coin box passage B.  
         [0028]    The fifth distributing unit  205  and the sixth distributing unit  206  are controlled by the solenoid SC 4 , and are integrally formed with a connecting plate  207  connected to this solenoid SC 4 .  
         [0029]    First, with reference to FIGS. 2, 4A and  4 B, and  5 A and  5 B, the description will be made of the fifth distributing unit  205 . The fifth distributing unit  205  distributes the 100 yen coins and 5 yen coins, which have been obtained by distributing by the fourth distributing unit  204 , to a coin tube CT 100  for 100 yen and a coin tube CT 5  for 5 yen. The fifth distributing unit  205  has back-and-forth distributing pieces  205   a ,  205   b  which are made of resin and are bifurcated, and lower ends of each distributing piece  205   a ,  205   b  are fixed to constitute a substantially V-character shape. Also, a coin passage A has a through hole  205   c  through which each distributing piece  205   a ,  205   b  is inserted, and each distributing piece  205   a ,  205   b  is adapted to reciprocate back-and-forth through the through hole  205   c  by means of excitation and non-excitation of the solenoid SC 5 .  
         [0030]    In this case, when it is not excited (OFF), as shown in FIGS. 4A and 5A, the solenoid SC 5  causes the 100 yen coins to roll to the rear-side distributing piece  206   b  for falling down and being received in the coin tube CT 100 . On the other hand, when in an excited state (ON), as shown in FIGS. 4A and 5B, the connecting plate  207  is drawn backward to thereby cause the 5 yen coins to fall down in the front-side distributing piece  206   a  for falling down and being received in the coin tube CT 5 .  
         [0031]    The sixth distributing unit  206  distributes the 10 yen and 50 yen coins which have been obtained by distributing by the third distributing unit  203  to the coin tube CT 10  for 10 yen and the coin tube CT 50  for 50 yen.  
         [0032]    This sixth distributing unit  206  has similar structure to the above-described fifth distributing unit  205 , and causes back-and-forth distributing pieces  206   a ,  206   b , which are bifurcated, to make frequent appearances from the coin passage A through the through hole  206   c . When the solenoid SC 4  is not excited (OFF), as shown in FIGS. 4A and 5A, the 10 yen coins are caused to fall on a rear-side distributing piece  206   b  for falling and being received in a coin tube CT 10 . On the other hand, when in an excited state (ON), as shown in FIGS. 4B and 5B, the connecting plate  207  is drawn backward to thereby cause the 50 yen coins to fall in the front-side distributing piece  206   a  for falling down and being received in the coin tube CT 50 .  
         [0033]    According to a coin distributing device structured as described above, it is possible to receive 500 yen, 100 yen, 50 yen, 10 yen and 5 yen coins which correspond to five coin tubes CT 500 , CT 100 , CT 50 , CT 10  and CT 5  respectively, and to use these coins as a coin for making change, and therefore, the commodity prices can be set in increments of 5 yen, and the degree of freedom for setting the prices can be increased.  
         [0034]    Also, since the structure is arranged such that the third distributing unit  203  and the fourth distributing unit  204  are driven by the common solenoid SC 3 , and the fifth distributing unit  205  and the sixth distributing unit  206  are likewise driven by the solenoid SC 4 , a driving source for six distributing units  201  to  206  requires four solenoids SC 1  to SC 4 , and the number of the driving sources is small.  
         [0035]    In this respect, in the above-described embodiment, the description has been made by using 5 yen coin, 10 yen coin, 50 yen coin, 100 yen coin and 500 yen coin, which are Japanese current coins, as an example, for the coins inserted, but the present invention is likewise applicable even to a coin distributing device for handling current coins in every country, for example, 5 cent coin, 10 cent coin, 25 cent coin, 50 cent coin and 1 dollar coin, which are American current coins.
