Description:
CROSS REFERENCE TO RELATED APPLICATIONS  
         [0001]    This application claims the benefit of priority under 35 U.S.C. § 119 of Japan Patent Application No. 2003-148245 filed May 26, 2003, the entire contents of which are incorporated herein by reference.  
         FIELD OF THE INVENTION  
         [0002]    This invention is related to a coin selector for distinguishing the authenticity of coins. The invention is particularly related to a coin selector which can be set up easily and surely as to permissible values for use in discriminating among coins such as upper limit values and lower limit values which define a permissible range for each coin or coin standard data for distinguishing coins. Furthermore, the standard data can be changed by only a limited number of people, to prevent theft. In this specification, the term “coin” includes coins, tokens, discs, etc.  
         BACKGROUND OF THE INVENTION  
         [0003]    This present applicant suggested in the past that one cannot easily change such coin standard data easily e.g.; distinguishing coins in a coin selector. This was mentioned for example in the patent document Japanese Laid Open Patent No. 2000-36067 (pages from 3 to 5, FIGS.  2 , 3 , 5  and  6 ) corresponding to the U. S. Pat. No. 6,125,987 (which is incorporated herein by reference). In this prior arrangement a key coin is entered into the coin selector. Subsequently the coin selector is changed to a sampling mode. In the sampling mode, the standard data can be collected. Next, genuine coins of a predetermined number are entered into the coin selector. Accordingly, the data can only be collected by using genuine coins. Therefore the standard data is made up based on the genuine coins data and is set up in a memory means at the coin selector. In the prior art, the standard data was made up based on coins which were received into the coin selector. Accordingly, the standard data was dependant on the assembly precision of the coin selector, and having a highly accurate distinction. Also, the method was limited to a person who has the key coin; for example only a manager can change the standard data with this method. However, such a person has to put in the coins into the coin selector. As a result, the procedure can be troublesome.  
           [0004]    For example, when the coins are 20 piece types in number and the coin selector requires 100 units to change the standard data, the operator has to put 2000 coins. Therefore, the changing operation takes a long time. Also, when the coins are put in oriented only with the same facing side (one-side facing the same direction) the resulting standard data is skewed. This leads to a genuine coin being distinguished as false.  
         SUMMARY OF THE INVENTION  
         [0005]    A primary purpose of this present invention is to provide a coin selector which can be easily set and in which the standard data can be set without putting coins into the coin selector.  
           [0006]    Another purpose of this invention is to provide both a coin selector and an outside setting unit which are not easily changed as to the standard data.  
           [0007]    As a solution to this problem, this present invention is structured based on the cooperating features as follows: A coin selector comprises a plural standard data memories for memorizing standard data, a selecting means which can be effective to select standard data memory based on a direction from an outside setting unit, a distinguishing means which compares the memorized data of said selected standard data memory and the outputting data of a coin sensor and outputs the authenticity signal, a gate controlling means which controls a gate based on an output from the distinguishing means.  
           [0008]    With the structure and system of the invention, the standard data for distinguishing coins are made up by preparations in advance where standard coins are put into a coin selector, and are memorized in the memory. When the setting is changed to a new setting data, the outside setting unit is connected to the coin selector. Next, a new standard data memory is selected by the selecting means. Entry coin data which is detected by a coin sensor is compared to the selected standard data by the distinguishing means, and is distinguished for authenticity. The gate controlling means is controlled based on the authenticity. Therefore the coins are diverted either to a genuine or a false passageway.  
           [0009]    The standard data for distinguishing coins are memorized or entered into the plural standard data memories in the coin selector. Also the memorized standard data becomes valid for selection as the occasion demands by an operation. Therefore standard coins are not put into the coin selector to change the standard data. As a result, the standard data can be easily changed.  
           [0010]    Also, the standard data which is memorized in the standard memory means can not be changed in an unauthorized manner, and is highly reliable. The operation is to make good use of the memorized standard data and such memorized standard data can be only set up by designated people which can use the outside setting unit. As a result, the standard data is not set up for the gain of non designated or unauthorized individuals. For example, only the manager can have the outside setting unit, and can reset or set up the standard data using the outside setting unit.  
           [0011]    This present invention is desirable, because such standard data memory memorizes the standard data from which it is established with the coin sensor based on an entered standard coin into said coin selector. In this structure, the standard data for distinguishing coins are made up or compiled whereby standard coins are put into a coin selector, at another location and in advance such that the data are memorized by the standard data memory. Therefore, the standard data is based on the coin selector&#39;s assembly precision or the parts precision. As a result, the distinguishing precision is highly reliable.  
           [0012]    This present invention is further desirable because such an outside setting unit and a selecting circuit can be connected up by a cable with a connector, said cable includes a signal line and a power line.  
           [0013]    In this structure and system of the invention, when the standard data is changed, the outside setting means and the coin selector are connected by the cable with the connector. The cable with the connector includes the signal line and the power line. Therefore, the outside setting unit is provided with the power from the coin selector. Accordingly, the outside setting unit does not need a power source. As a result, the outside setting unit is small and light weight and is generally convenient to transport.  
           [0014]    The present invention is further desirable, because the outer setting unit includes selecting switches for the standard data and a selecting executing switch. In this structure, the standard data is selected from a plurality of memorized standard data which are memorized in plural memory locations (plural memories) of the coin selector by the selecting switches. Next, the selected standard data comes into effect by the selecting executing switch.  
           [0015]    Therefore, the standard data becomes valid in two operations which are, by use of the selecting switch and the selecting executing switch. As a result, the changing operation is easier. Also, when the changing operation continues, only the selecting executing switch is operated. As a result, the operation is easier.  
           [0016]    The present invention is also desirable because the outer setting unit includes a standard data preparing means on the outer setting unit. In this structure and system according to the invention, newly provided standard data can be set up on the coin selector by entering some new coins. Therefore a new standard data can be set up easier.  
           [0017]    The present invention is further more desirable as said outer setting unit includes a adjusting volume indicating means. With this structure, when a new standard data is made up, the sensitivity set for the standard coin can be seen on the adjusting volume indicating means by the operator. Therefore the operator can easily set up the standard data.  
           [0018]    This present invention is desirable, because said adjusting volume indicating means provides that the emitting position is changeable together with the adjusting volume. In this structure, when newly standard data is made up, the sensitivity in the standard coin can be seen on the adjusting volume indicating means by the operator. The emitting position on the adjusting volume indicating means is changed based on the sensitivity. Therefore the adjusting operation is easier.  
           [0019]    The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which a preferred embodiment of the invention is illustrated.

     DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0027]    Referring to the drawings in particular, the structure of a coin selector  1  is firstly explained. A coin selector  1  is box like in shape and is attached into, for example, slot machines or other coin based machines (gamming machines, arcade game machines, vending machines, etc.) and can use a known coin selector; for example the selector known from U.S. Pat. No. 6,056,105 (which is hereby incorporated by reference).  
         [0028]    The coin selector  1  includes a mechanical section  4  and an electric section  6 . The mechanical section  4  includes a coin passageway  14  which continues to entry slot  12 . A gate  16  is located at the lower section of the coin passageway  14  as well as a genuine coin passageway  28  and a false coin passageway  30 . The electric section  6  includes coin sensor  20  which detects data for distinguishing passed through coin  18  and selecting circuit  21 .  
         [0029]    The structure of mechanical section  4  is explained below in particular. A coin passageway  14  has the function such that the coin  18  which entered into entry slot  12  is guided at a predetermined position. The passageway  14  is made up as a slant, a perpendicular (to the entry opening or horizontal) path or a curve. The coin passageway  14  in embodiment of FIG. 2 is a perpendicular path and sensor  20  is located at the upper section thereof. The gate  16  has a function such that the falling coin  18  in coin passageway  14  is diverted to either the genuine passageway  28  or the false passageway  30 .  
         [0030]    In this embodiment, the gate  16  can go in and out of the coin passageway  14  which is located downstream of the coin sensor  20 . When the coin  18  is genuine, the gate  16  is located outside of coin passageway  14 . When the coin  18  is false, the gate  16  is located inside of the coin passageway  14 . In other words, when the coin is genuine, a solenoid  32  is excited, and the gate  16  is removed to the outside of the coin passageway  14 . When the coin is false, the solenoid  32  is not excited, and the gate  16  is kept in coin passageway  14  by a spring (not shown). Accordingly, a false coin which falls in the coin passageway  14  is guided into the false coin passageway  30  by the gate  16 , and is returned into a return slot (not shown). A genuine coin is guided into genuine coin passageway  28 , and is guided into a safe (not shown) or holding container.  
         [0031]    Next, the structure of the electric section  6  is explained. The sensor  20  has a function which detects data (feature data or characteristics data); for example a diameter, a material and a thickness of coin for distinguishing genuine or false coins, and it can be made up by electric, optical, magnetic, etc. sensor elements and combinations thereof The sensor  20  can be selected for only one diameter, material or thickness, however it can use combined or plural parameters. When the plural parameters are selected, the genuineness accuracy becomes highly accurate and this is desirable. In this embodiment, three coils  22 , 24 , 26  are positioned around the coin passageway  14 , and can detect a diameter, a material and a thickness for distinguishing between fake and genuine coins.  
         [0032]    The coils  22 , 24 , 26  can be made up around a cylinder core, and may be located adjacent to the coin passageway  14 . The coil  22  is used for detecting the diameter data, the coil  24  is used for detecting the material data and coil  26  is used for detecting the thickness data.  
         [0033]    Next the selecting circuit  21  is explained. The selecting circuit  21  is fixed at a section which is shown in a dotted line at the side of coin passageway  14 . A block diagram of selecting circuit  21  is shown at the right for convenience as shown in FIG. 2. Oscillating circuits  34 ,  36 ,  38  are connected to the coils  22 , 24 , 26 . The oscillating circuit  34  is connected to the distinguishing means  54  through rectifying circuit  40  and A/D converting circuit  48 . The oscillating circuit  36  is connected to the distinguishing means  54  through rectifying circuit  42  and A/D converter  50 . The oscillating circuit  38  is connected to the distinguishing means  54  through rectifying circuit  46  and A/D converter  52 .  
         [0034]    Also, there is standard data memory  56  which memorizes standard data for distinguishing coins. In this embodiment, the U. S. coins are used. Therefore, there is a new 1 cent standard data memory  58 , a 5 cent standard data memory  60 , a 10 cent standard data memory  62 , a 25 cent standard data memory  64 , a 50 cent standard data memory  66 , a 1 dollar standard data memory  68 , an old 1 cent standard data memory  70  and standard data memory  71  on board.  
         [0035]    The standard data memories  58 ,  60 ,  62 ,  64 ,  66 ,  68 ,  70 ,  71  memorizes standard data (information as to denominations, and adjusting limits) for distinguishing genuine coins. The denomination information is limited to selected denominations for the process of distinguishing coins as their being genuine. The limited information is a coefficient which adjusts the denomination information for expanding or reducing the number of denominations. These standard data memories are connected to the distinguishing means  54  through the selecting means  72 . The selecting means  72  has a function where only one set of standard data, which is selected by the outside setting unit  74  from the standard data memory  58  to  71 , is usefully selected.  
         [0036]    The distinguishing means  54  has the function of receiving data as to the entered coin  18  from coils  22 , 24 , 26  and standard data which is received from selecting means  72 . The distinguishing means  54  compares the coin data and the standard data and the authenticity of entered coin  18  is distinguished. Where the data received by the coils are within the limits, the coin is distinguished as genuine, also when the data is not within the limits, the coin is distinguished as false. When the coin  18  that has been fed in is genuine, solenoid  32  is excited at a predetermined time through gate controlling means  76 .  
         [0037]    A communicating means  75  and power means  77  are also provided as shown in FIG. 2. The communicating means  75  communicates to the outside setting unit  74  for changing standard data memory  56  of selecting means  72 . The power means  77  supplies electric power to the block circuit and outside setting circuit  84 . Distinguishing means  54 , selecting means  72  and gate controlling means  76  are provided via programing in microprocessor  79 . A connector  78  connects to the outside communicating circuit  84 . The connector  78  is fixed at selecting circuit  21 . The circuit  21  is connected to ground through a diode  181 .  
         [0038]    The connector  78  is located at the valley between coin passageway  14  and attaching flange  80 . Accordingly, connector  78  is protected by coin passageway  14  and attaching flange  80 . As a result, when coin selector  1  is transported, connector  78  does not receive damage. Also, luminous element  81  is located below connector  78  and indicates a situation or status of selecting circuit  21 .  
         [0039]    Next, the outside setting unit  74  is explained referring to FIGS. 1 and 3. The outside setting unit  74  includes a box  82  which is a handheld and an outside setting circuit  84  which is built in the box  82 . A connector  86  is attached at the outside setting circuit  84  and is connected to the connector  78  of the selecting circuit  21  through a LAN cable  88 . The LAN cable  88  includes a signal line  89  and a power line  91 . A connector  93 , which is located at the end of LAN cable  88 , can be detached and attached to the connector  86 , and a connector  95  at another end can be detached and attached to the connector  78 .  
         [0040]    An emitting element  90 , for indicating power, is located at the left upper section of the box  82  and emits light when the power is supplied. The emitting element  92  indicates the situation of the selecting circuit  21 . The emitting element  92  is located near the right side of emitting element  90  and emits light when the selecting circuit  21  is busy. Selecting switches  94 ,  96 ,  98 , 100 , 102 , 104 ,  106  are provided for setting the denominations. These selecting switches are in a row at a predetermined distance and are located near and below the emitting elements.  
         [0041]    Emitting elements  108 , 110 , 112 , 114 , 116 , 118 , 120  are provided for indicating denomination. These emitting elements  108 , 110 , 112 , 114 , 116 , 118 , 120  are located adjacent to and over the switches, and emit light when the denomination is selected. In this embodiment, the switch  94  and the emitting element  108  correspond to the 1 cent coin, the switch  96  and the emitting element  110  correspond to the 5 cent coin, the switch  98  and the emitting element  112  correspond to the 10 cent coin, the switch  100  and the emitting element  114  correspond to the  25  5 cent coin, the switch  102  and the emitting element  116  correspond to the 50 cent coin, the switch  104  and the emitting element  118  correspond to the 1 dollar coin and the switch  106  and the emitting element  120  correspond to the old 1 cent coin.  
         [0042]    An executing selecting switch  122  is provided for changing the selected selecting means  72 . The executing selecting switch  122  is located near and below selecting switch  104  and  106  and is a push button system. A selecting changing means  124  is made up by the emitting elements  108 , 110 , 112 , 114 , 116 , 118 , 120  for indicating the selected denomination, the selecting switches  94 , 96 , 98 , 100 , 102 , 104 , 106  and the executing selecting switch  122 . An on board setting switch  126  which is a toggle system, a digital rotary switch  128 , an adjusting amount indicating means  130  and an on board executing setting switch  132  are located in a row and below the executing selecting switch  122 .  
         [0043]    The adjusting amount indicating means  130  includes  15  emitting elements which are positioned side by side to form a crank-like shape. The standard emitting element is located at the middle. When the amount of the digital rotary switch  128  is higher than a standard amount, an emitting element, at the right side to the middle, lights as shown in FIG. 1. When the amount is lower than the standard amount, an emitting element at the left side to the middle, lights. The emitting element  133  for indicating the on board setting mode is located adjacent to and above the on board setting switch  126 . The on board standard setting means  134  is made up by the on board setting switch  126 , the on board executing setting switch  132 , the digital rotary switch  128  and the on board setting mode indicating emitting element  133 .  
         [0044]    The outside setting circuit  84  is made up by a microprocessor  135 , the emitting elements  90 , 92 , the selecting switches  94 , 96 , 98 , 100 , 102 , 104 , 106 , the executing selecting switch  122 , the emitting elements  108 , 110 , 112 , 114 , 116 , 118 , 120 , the on board setting switch  126 , the digital rotary switch  128 , the adjusting amount indicating means  130 , the on board executing setting switch  132  and the emitting element  133  for indicating on board setting mode as shown in FIG. 3. Also, the emitting element is a LED (light-emitting diode) and it is desirable from the point of view, for example; of it being miniature, of it having low amounts of power consumption and being low in cost. Also, the emitting element can be changed to another indicating means.  
         [0045]    Next, the operation of this embodiment is explained. Firstly, an initial setting process at the time of a shipment is explained. An initial setting unit (not shown) which is structured in the same manner as outside setting unit  74  is connected to selecting circuit  21  through the LAN cable  88 . In step S 1 , selecting switch  94  is turned to “ON”, and standard data memory  58  corresponding to 1 cent is selected.  
         [0046]    Next, in step S 2 , a standard 1 cent coin is entered into entry slot  2 . In step S 3 , the standard 1 cent coin data is received. In other words, an eddy current occurs in the coin  18 . Accordingly, the oscillations of coils  22 , 24 ,  26  are changed by the eddy current. In other words, the oscillating circuit  34  connected to coil  22  provides the current to the rectifying circuit  40  which corresponds to the diameter of coin  18 . The oscillating circuit  42  connecting to coil  24  provides the current to the rectifying circuit  42  which corresponds to the metal of coin  18 . The oscillating circuit  38  connecting to the coil  26  provides the current to rectifying circuit  46  which corresponds to the thickness of coin  18 .  
         [0047]    The rectifying circuits  40 , 42 , 46  rectify the currents, and afterwards they supply the rectified currents to AD converters  48 , 50 , 52 . The AD converters  48 , 50 , 52  convert from the analog signal to a digital signal. Next in step S 4 , the received data is distinguished to correspond to a predetermined quantity; for example 10. When the quantity does not satisfy 10, the program returns to step S 2 . When the quantity corresponds to 10, the program goes to step S 5 . In step S 5 , the received data which is referring to the diameter of the coin, the metal and the thickness are processed at a predetermined process. Then, the standard data of the 1 cent coin is formed or made up.  
         [0048]    In step S 6 , the made up standard data referring to the 1 cent coin is memorized or stored into memory  58 . Therefore, in the initial setting process, the standard data includes an acceptable error with regard to variations in manufacturing the coin passageway  14  and coils  22 ,  24 , 26 .  
         [0049]    Next, memorizing circuit  60  for the 5 cent coin is selected and is turned on. Afterwards, the standard data is memorized in memorizing circuit  60  in the same manner as the above-mentioned for the 1 cent coin. As the same as the above-mentioned, the standard data for the 10 cent coin, the 25 cent coin, the 50 cent coin, the 1 dollar coin and the old 1 cent coin are made up, and are memorized in corresponding to the memories. Afterwards, coin selector  1  is sent to an owner/operator. In this embodiment, the standard data corresponds to 7 denominations; however it can be changed at will.  
         [0050]    The owner/operator attaches the coin selector  1  to a slot machine or other coin machine. Afterwards, the receiving denomination is set by the owner. The setting process is explained referring to FIGS. 5 and 6. Firstly, the connector  93  of the LAN cable  88  is inserted into the connector  86  of outside setting circuit  84  and another connector  95  is inserted into the connector  78  of the coin selector  1 .  
         [0051]    Therefore, power is supplied to the outside setting circuit  84  through the power line  91 . The outside setting circuit  84  starts the process, then the emitting element  90  for indicating the power emits light. In step S 11 , the outside setting circuit  84  initializes the microprocessor  135 , and the program goes to the step S 12 . In step S 12 , a command for identifying the situation is outputted to the selecting circuit  21 . In step S 31  based on the power in the selecting circuit  21 , the microprocessor  79  is initialized, afterwards the program goes to step S 32 . In step S 32 , the normal selecting mode program starts. In other words, when the coin  18  is entered into the entry slot  12 , the after-mentioned authenticity program is executed, and the coin  18  is distinguished. When the coin  18  does not enter, the program goes to step S 33 , a situation identifying command which is outputted by the outside setting circuit  84  is distinguished. When the situation identifying command is not distinguished, the program goes to step S 34 . In step S 34 , the executing selecting command which is outputted by the outside setting unit  74  is distinguished. When the executing selecting command is not distinguished, the program goes to step S 35 .  
         [0052]    In step S 35 , the on board standard data making command which is outputted by outside setting unit  74  is distinguished. When the on board standard data making command is not distinguished, the program returns to step S 32 . In other words, when a coin is not entered and each of the executing switches are not operated (not ON), the program of selector circuit  21  loops from step S 32  to S 35 . In step S 33 , the situation identifying command is distinguished at step S 12 , and the program goes to step S 36 .  
         [0053]    In step S 36 , “information of selecting denomination ” and “information of adjusting limit ” which are set up in the selecting circuit  21  are transmitted to the outside setting circuit  84 . In step S 13 , when the outside setting circuit  84  receives the information, the program goes to step S 14 . The emitting element corresponding to the denomination which was selected from emitting element  108  to  120  is emitted. Also, the emitting element corresponding to the limit which was selected based on the information of the adjusting limit is emitted. When the information is not installed, the emitting elements do not emit.  
         [0054]    In this case, the emitting elements do not emit, because the information of selected denomination and the information of the adjusting limit is not set up. In step S 15 , “ON” of executing selecting switch  122  is distinguished. When it is “OFF”, the program goes to step S 16 . In step S 16 , “ON” of on board executing selecting switch  132  is distinguished. When it is “OFF”, the program returns to step S 12 . In other words, when each executing switch is not operated, the program in the outside setting circuit  84  loops from step S 12  to S 16 . When the denomination is changed, a predetermined switch goes to “ON”. For example, where the selecting switch  100  corresponding to the 25 cent coin is “ON”, next the executing selecting switch  122  is pushed. In this situation, the executing selecting switch  122  is “ON” in step S 15 , therefore the program goes to step S 17 . In step S 17 , the executing selecting command which includes the information of denomination and adjusting limit of selecting switch  100  is outputted to selecting circuit  21 .  
         [0055]    When selecting circuit  21  distinguishes the executing selecting command in step S 34 , the program goes to step S 37 . In step S 37 , the information as to the denomination (25 cent in this embodiment) and the adjusting limit (a median in this embodiment) is analyzed, afterwards the program goes to step S 38 . In step S 38 , when selecting switch  126  is not “ON”, the program goes to step S 39 . In step S 39 , the standard data (information of denomination and adjusting limit) of 25 cent which is memorized on standard data memory  64  becomes valid, afterwards the program goes to step S 35 .  
         [0056]    In step S 35 , when the on board standard data starting command is distinguished, the program returns to step S 32 , afterwards the program goes from step S 33  to step S 36 . In this process, the valid information of denomination and adjusting limit is transmitted to outside setting circuit  84 . The outside setting circuit  84  receives the information, afterwards in step S 14 , the emitting element  114  corresponding to the information emits and the emitting element of the adjusting limit indicating means  130  corresponding to the information emits.  
         [0057]    Next, the situation where standard data was not memorized in the standard data memory  58  to  70  is explained. For example there is a case where new tokens are used in a slot machine or in a vending machine or game machine. In other words, the process where the standard data for distinguishing a new token or coin is to be memorized or saved to the on board standard data memory  71  is explained below.  
         [0058]    Firstly, as above-mentioned, connector  95  of LAN cable  88  is inserted into connector  78  of coin selector  1 . Therefore power is supplied to the outside setting circuit  84 . The outside setting circuit  84  starts the process, then emitting element  90  for indicating the power emits light. When on board executing setting switch  132  is pushed and becomes “ON”, the program goes from step S 16  to step S 18 .  
         [0059]    In step S 18 , the program in the outside setting circuit  84  outputs an on board standard data making starting command to selecting circuit  21 . Afterwards the program goes to step S 19 . In step S 19 , when “ON” of the on board executing setting switch  132  is detected again, the program goes to step S 20 . In step S 20 , the command for stopping the making of the on board standard data is transmitted to coin selecting circuit  21 .  
         [0060]    When the on board executing setting switch  132  is not pushed, the program goes to step S 21 . In step S 21 , the finishing command for making the on board standard data is distinguished. When the finishing command is distinguished, the program returns to step S 12 . When the finishing command is not distinguished, the program returns to step S 19 . When the selecting circuit  21  receives the starting command for making the on board standard data in the selecting circuit  21 , the program goes from step S 35  to step S 42 .  
         [0061]    In step S 42 , when the stopping command for making on board standard data is not distinguished, the program goes to step S 43 . When on board executing setting switch  132  is pushed again; in other words, when the stopping command is received, the program returns to step S 32 . In step S 43 , when coin  18  is distinguished, the program goes to step S 44 . In step S 43 , when coin  18  is not distinguished, the program returns to step S 42 .  
         [0062]    Next, in step S 43 , when a new coin is distinguished, the program goes to step S 44 . In step S 44 , the data which is received from coils  22 , 24 , 26  are memorized in the internal memory of microprocessor  134  through oscillating circuits  34 , 36 , 38 , rectifying circuit  40 , 42 , 46  and AD converter  48 , 50 ,  52  as above-mentioned. Next, in step S 45 , the number of times of sampling or getting the data is distinguished. The number of times of receiving or getting the data is set up beforehand; for example it is desirable to sample or get from 10 to 20 times from the point of view of ensuring that the operation is reliable. In this embodiment, it is set up at 10 times.  
         [0063]    In this case, it is first time, the program returns to step S 42 . When the data is received 10 times, the program goes to step S 46 . In step S 46 , a predetermined process is executed based on the received data, and a new standard data (information of denomination) is made up, and the program goes to step S 47 . In step S 47 , the new standard data is memorized in standard data memory  71 , and the program goes to step S 48 .  
         [0064]    In step S 48 , a finishing command for sending on board is outputted to outside setting circuit  84 . In step S 21  in the outside setting circuit  84 , when the finishing command is distinguished, the program returns to step S 12 , afterwards the program goes to the standby situation.  
         [0065]    When the adjusting limit of newly setting standard data is adjusted, on board setting switch  126  is turned on, afterwards executing selecting switch  122  is pushed. Accordingly, the program in selecting circuit  21  goes from S 34  to S 37 , the information of the denomination and the adjusting limit of the standard data memory  71  is analyzed. The denomination information of the newly installed standard data is analyzed, however the adjusting limit information is not memorized. Next, in step S 38 , selecting switch  126  is turned on, therefore the program goes to step S 40 .  
         [0066]    In step S 40 , the setting information of the digital rotary switch  128  is analyzed, afterwards the program goes to step S 41 . In step S 41 , the setting data of digital rotary switch is memorized in the standard data memory  71 , and the program returns to step S 39 . In step S 39 , the standard data which is analyzed in step S 37  is set up, afterwards the program returns to step S 35 .  
         [0067]    Therefore the digital rotary switch  128  is adjusted to a predetermined amount, afterwards the executing selecting switch  122  is pushed. As a result, the adjusting limit can be adjusted. In step S 14  in the outside setting circuit  84 , the emitting element  133  which is the newly set up denomination and the emitting element of the adjusting limit emitting element  130  corresponding to new adjusting limit are emitted.  
         [0068]    Also, the situation indicating emitting element  92  of the outside setting unit  74  indicates a situation of the microprocessor  79  of the selecting circuit  21 . For example, when the microprocessor is busy, the emitting element emits. When the setting of many slot machines (or vending machines, gaming machines, arcade machines) are continuously changed to 25 cent, selecting switch  100  is continuously turned on, and connector  95  of LAN cable  88  is pulled out, afterwards the connector  95  is inserted into connector  78  of next coin selector  1 .  
         [0069]    Therefore, the power is supplied to the outside setting circuit  84 , and the emitting element  90  for indicating power emits. In step S 15 , when executing selecting switch  122  is turned on, the program goes to step S 27  in selecting circuit  21  as the same as above-mentioned. Therefore the information of denomination and adjusting limit of selecting switch  100  which is turned on is analyzed. Next, in step S 38 , selecting switch  126  is turned off, and the program goes to step S 39 . In step S 39 , the standard data memory  64  corresponding to analyzed 25 cent becomes effective. In the other slot machines (or other coin machines), the operation is operated in the same manner as above-mentioned. As a result, the slot machines (or other coin machines) are changed to the same denomination.  
         [0070]    Next, the distinguishing of the authenticity based on a setting as above-mentioned of the entered coin is explained referring to a flow-chart in FIG. 7. Firstly, in step S 51 , a coin  18  is entered. In step S 52 , data referring to a diameter, a metal type and a thickness are received by coils  22 , 24 , 26 .  
         [0071]    Next, in step S 53 , the received data is compared with the standard data of the standard data memory which is selected and which came into effect, for example 25 cent which is memorized in memory  64 . When the received data is outside of the standard data, in other words, when the coin is false, the program goes to step S 51 . Therefore, gate  16  is continuously located at coin passageway  14 , the false coin  18  is diverted to the side by gate  16 , and goes to false passageway  30 .  
         [0072]    When received data is within the standard data; in other words, when the entered coin is genuine, the program goes to step S 54 , the solenoid  32  is excited at a predetermined time by the gate controlling means  76 . Therefore, gate  16  goes out from coin passageway  14 , and coin  18  can fall, then the coin  18  goes to the genuine passageway  28 , and it is stored in the safe.  
         [0073]    According to the present invention, the standard data for distinguishing a coin is memorized in the standard data memory. Also, one set of the standard data comes into effect as the need arises by appropriate selection. Therefore, entering standard coins on the selector is not needed. As a result, the standard data can be easily changed. Also, the standard data which is memorized in the memory comes into effect. In other words, the standard data is not newly communicated. As a result, the reliability of the standard data is higher.  
         [0074]    Putting the memorized standard data into effect can be done by only one person which has the outside setting unit. For example, a limited number of persons have the outside setting unit. As a result, the standard data can be changed by the limited number of persons. Also, the standard data for distinguishing coins is made up by entering the standard coins into the coin selector beforehand, and is memorized in the memory. Therefore the standard data is based on the coin selector&#39;s assembly precision or the parts precision. As a result, the distinguishing precision is higher.  
         [0075]    Also, the outside setting unit is miniature and lightweight, because the outside setting unit does not have a power source. The changing of the standard data is easier, because only the selecting switch for the standard data and the executing selecting switch are operated.  
         [0076]    The new standard data can be set up on the coin selector by entering new coins. Therefore new standard data can be set up easier. Also, when new standard data is made up, the sensitivity in the standard coin can be seen on the adjusting volume indicating means by the operator. Therefore the adjusting operation is easier.  
         [0077]    While a specific embodiment of the invention has 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.
