Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a totaling device for a vending machine, and more particularly to one that performs a totaling process based on coins entering and exiting the vending machine.

<Conventional technology> Conventionally known vending machine sales aggregation devices are
It received sales price data of sold products and added up the total. Although sales can be determined using this method, it is not possible to tabulate the amount of money received and received by denomination. If sales are aggregated based on the inflow and outflow of money from vending machines, it is possible to aggregate sales by denomination as described above. However, such a totaling device for vending machines has not conventionally existed.

<Problems to be Solved by the Invention> When trying to perform sales aggregation processing based on coins being put in and taken out of a vending machine, it is necessary to add and subtract a signal from an input coin detection switch and a signal from a coin withdrawal detection switch. However, in this case, the wiring would have to be extended from the switch to the totalizing device, which would be troublesome, and the extended wiring would also cause problems such as noise. Furthermore, in order to draw out the wiring from the switch, the circuit within the changer device including the switch must be changed.

This invention was made in view of the above points,
The present invention aims to provide a totaling device for a vending machine that does not have the above-mentioned problems.

<Means for Solving the Problems> The aggregation device according to the present invention includes a first means for detecting an increase/decrease amount of change in amount display data indicating an amount displayed on an amount display device; a second means for counting up and down in accordance with the amount of change; and a second means counting the amount of decrease in amount display data caused by subtracting the selling price at the time of product sale based on the sales start signal. The present invention is characterized in that a count value corresponding to the final amount of money is left in the second means.

<Function> The totaling device of the present invention having the above-described configuration detects the entry and exit of coins into and out of the vending machine using the amount display data indicating the amount displayed on the amount display of the vending machine, and performs the totaling process. I try to do this. The amount display data increases by the amount when a coin is inserted, and decreases by the amount when the coin is dispensed. Therefore, by monitoring the increase/decrease in the amount display data, it is possible to know whether coins are in or out. This results in
There is no need to extend the wiring from the input coin detection switch or the coin output detection switch and use it for tally processing. By the way, the amount display data decreases not only when coins are paid out, but also when the selling price of the sold product is subtracted. Therefore, in this invention, it is distinguished whether the decrease in the amount display data is due to the dispensing of coins or the subtraction of the selling price, and if the decrease in the amount display data is due to the subtraction of the selling price, it is determined in the aggregation process. The feature is that the decrease is ignored. To make this distinction, a sales start signal indicating that a product has been sold is used. That is, the aggregation device of the present invention adds up the amount of coins inserted by counting up the increase in the amount display data of the vending machine,
By prohibiting the countdown of the decrease in the amount display data due to sales price subtraction after the sales start signal is generated, the decrease is ignored, but by counting down the subsequent decrease in the amount display data, it is possible to prevent the decrease after the sales price is collected. The amount of change coins paid out is subtracted from the amount of coins inserted, so that the final amount received (sales amount) remains. The total sales amount is compiled by accumulating this amount of revenue.

By the way, the amount display data increases or decreases each time a coin is inserted or paid out, so by monitoring the increase or decrease in the amount display data from time to time, it is possible to determine the amount of money inserted or paid out by the increase or decrease. The denomination of the coin can be easily identified. Therefore, in this invention, the denomination of the coins inserted or dispensed is determined from the increase/decrease in the amount display data, and the number of coins inserted and the number of coins dispensed are added or subtracted for each denomination, and the collected amount is aggregated by denomination. making it possible.

As the amount display data, the signal input from the changer device to the amount display device may be incorporated into the totalization device (as is the case in the following embodiment), or the signal input from the changer device to the amount display device may be used. The contents of the addition/subtraction counter for counting coins (indicating the displayed amount) may be directly taken out and used in the totaling device.

<Embodiment> Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, a vending machine main body 10 is an existing vending machine having any configuration, to which a totalizing device 11 according to the present invention is added. The vending machine main body 10 is roughly divided into a changer device 1.
2, a vendor control section 13, and an amount display 14. The changer device 12 has a function of determining the genuineness of the inserted coins and accepting the genuine coins, and adding and counting the amount of the accepted inserted coins, and based on the comparison between the inserted amount and the set selling price, if the amount is within the range of the inserted amount. A function that generates a sellable signal (VE) corresponding to a product that can be sold, a function that subtracts the selling price of the sold product from the input amount and pays out the remaining amount as change.
It has various well-known functions. The vendor control unit 13 accepts a sellable signal (VE) generated from the changer device 12, and when the product selected by the product selection switch (not shown) is sellable, disburses the product. and sends a sales start signal (VS) to the changer device 12 indicating that the product is in a product delivery state (sales state). In the changer device 12, when a sales start signal (VS) is given, the change amount is calculated by subtracting the set selling price of the sold (selected) product from the input amount, and then the amount of change is calculated. Pay out coins. The electrical (electronic) circuit section within the changer device 12 is unitized, and the electrical circuit section within the changer device 12 and the electrical circuit section of the bender control section 13 are removably connected via a connector 15. Through wiring via this connector 15, a sales enable signal (VE), a sales start signal (VS), a product selection signal, etc. are transmitted and received.

The changer device 12 includes an addition/subtraction counter 16 that adds up the amount of coins inserted, subtracts the price of the sold product, and also subtracts the amount paid out as change. The amount counted by the addition/subtraction counter 16 (the input amount or its remaining amount) is displayed on the amount display 14.

That is, the changer device 12 and the amount display 14 are detachably connected via the connector 17, and a signal indicating the amount counted by the addition/subtraction counter 16 is transmitted to the amount display 14 via the connector 17.
supplied to

The count content of the addition/subtraction counter 16 changes as coins are inserted, products are sold, or change is paid out. In other words, each time a coin is inserted, the count increases by an amount commensurate with the denomination of the inserted coin, and when a product is sold, it decreases by the selling price, and when change coins are paid out, The amount will be reduced by the amount commensurate with the denomination of the coin you paid out. For example, the total is 10 yen, 50 yen, 10 yen, 10 yen, 50 yen.
A 130 yen coin is inserted, then a 100 yen item is sold, and then three 10 yen coins are given as change (30 yen).
Assuming that the numbers are paid out in order, the contents of the count of the addition/subtraction counter 16, that is, the amount display signal given to the amount display 14 are as follows: "0" → "10" → "60" →
"70" → "80" → "130" → "30" → "20" →
It changes from "10" to "0".

In addition, the selling price (100 yen) is calculated from the total input amount (130 yen).
yen) is subtracted after the sales start signal (VS) is given.

The denomination of the inserted coin or the dispensed coin can be determined from the count of the addition/subtraction counter 16, that is, the change (increase or decrease) in the amount display signal of the amount display 14. The totaling device 11 monitors the state of the amount display signal given from the changer device 12 to the amount display 14, and adds or subtracts the input amount and the payout amount for each denomination according to the increase or decrease. If the amount display signal decreases as a result of subtracting the selling price, the totaling device 11 is configured not to perform subtraction counting. Whether or not the sales price has been subtracted is determined by whether or not the sales start signal (VS) is generated. The aggregation device 11 adds up the input amount for each denomination and subtracts the disbursed amount for each denomination, so that the amount of money accepted into the vending machine (sales amount) as a selling price is totaled for each denomination.

A more detailed example of the amount display signal given from the changer device 12 to the amount display 14 and the totalization device 11 will be described next.

In the changer device 12, the count contents of the addition/subtraction counter 16 are converted into a predetermined display element drive signal by a display driver 18 and output. For example, the display element drive signal is a 7-segment signal S required to display a number of one display digit.
1 to S7 and digital strobe pulse DS1,
Consists of DS2 and DS3. Segment signal S1~
Each of S7 corresponds to each of the seven display elements constituting one display digit. That is, as is well known, each digit of the display 14 can display all numbers from 0 to 9 by lighting combinations of seven display elements, and the segment signals S1 to S
7 is a signal in which a predetermined number (several of S1 to S7) is "1" and the rest are "0" depending on the desired number to be displayed.

The amount display 14 has four display digits corresponding to the ones, tens, hundreds, and thousands digits, and the display of the ones digit is fixed to "0". This is because the minimum unit of coin used is 10 yen. Therefore, it is possible to display up to 9990 yen. Segment signals S1 to S7 are outputted from the time-sharing changer device 12 (display driver 18) in correspondence with the tens digit, the hundreds digit, and the thousands digit. Digit strobe pulse DS1, DS
2 and DS3 are generated in synchronization with the time division timing of the segment signals S1 to S7, and indicate which display digit the segment signals S1 to S7 correspond to currently being output. Pulse DS1 is tens place, DS2
corresponds to the hundreds place, and DS3 corresponds to the thousand place. Digit strobe pulses DS1, DS2, and DS3 are generated corresponding to digits to display some number (0 to 9). When the count of the addition/subtraction counter 16 is 0, not only the segment signals S1 to S7 but also the digit strobe pulses DS1 to DS3 are not generated.

Digit strobe pulse DS1, DS2, DS
An example of occurrence of No. 3 is shown in Fig. 2. For example, "150"
When displaying (yen), pulse DS1 is generated when segment signals S1 to S7 for displaying "5" in the tens digit are output, and a pulse DS1 is generated to display "1" in the hundreds digit. Pulse DS2 is generated when signals S1 to S7 are output. in this case,
Since nothing is displayed in the thousands digit, the digit strobe pulse DS3 corresponding to the thousands digit is not generated, and pulses DS1 and DS2 are repeatedly generated. In addition, when displaying "1000" (yen), pulses are generated corresponding to segment signals S1 to S7 for the tens digit "0", the hundreds digit "0", and the thousands digit "1". DS
1, DS2, and DS3 are generated, respectively. When displaying "0", segment signals S1 to S7 are not generated, and therefore pulses DS1 to DS3 are not generated.

Wiring of the amount display signal output from the changer device 12, that is, segment signals S1 to S7
A total of 10 wires of digit strobe pulses DS1 to DS3 are connected to the amount display 14 via the connector 17, and the same amount display signals (segment signals S1 to S7 and pulses DS1 to DS3) are taken out from the connector 17. and input into the aggregation device 11. Also, from the vendor control unit 13 to the connector 15
A sales start signal (VS) supplied to the changer device 12 via the connector 15 is also taken out and inputted to the totalizing device 11.

In this embodiment, the aggregation device 11 is constituted by a microcomputer, and a program
ROM (abbreviation for read-only memory; the same applies hereinafter)
19, CPU (abbreviation for central processing unit, the same applies hereinafter) 20, and RAM that stores the total sales amount by denomination.
(Abbreviation for random access memory, same hereinafter) 21
Contains. Amount display signals (segment signals S1 to S7, digit strobe pulses DS1 to DS3) inputted to the totalization device 11 are applied to the CPU 20 via an interface circuit 22.
At this time, the segment signals S1 to S7 are converted into a 4-bit binary coded decimal number Dsg by the encoder 23 and then inputted to the CPU 20. Connector 15
Sales start signal VS inputted to the aggregation device 11 from
is connected to the CPU 2 via the interface circuit 24.
Add to 0.

The CPU 20 includes a current displayed amount register Mn' that stores data indicating the currently displayed amount on the amount display 14, and a previous displayed amount register Mn that stores data that indicates the immediately previous displayed amount. , Mn are compared by the comparison means COM to detect a change. Furthermore, CPU20
Then, the counters by denomination R ₁₀ , R ₅₀ , R ₁₀₀ (actually they are not independent counters but registers,
(functions as a counter in combination with the calculation function in the CPU), and the comparison means COM
The contents of appropriate counters (R ₁₀ , R ₅₀ , R ₁₀₀ ) are counted up or down by 1 depending on the difference between the contents of registers Mn' and Mn detected at .

The counters R ₁₀ , R ₅₀ , and R ₁₀₀ are used to total the sales amount for each denomination in one sale, and the cumulative total of the sales amount is stored in the sales amount totaling RAM 21 . This RAM21 has a storage section Rex ₁₀ for each denomination,
Consisting of Rex ₅₀ and Rex ₁₀₀ , the contents of the denomination-specific counters R ₁₀ , R ₅₀ , and R ₁₀₀ are added to the contents of the memory section Rex ₁₀ , Rex ₅₀ , and Rex ₁₀₀ for the same denomination, respectively, each time one sale is completed. The result of the addition is stored in the memory section Rex ₁₀ ,
The memory contents of Rex ₅₀ and Rex ₁₀₀ will be rewritten. Thereafter, the contents of counters R ₁₀ , R ₅₀ , and R ₁₀₀ are cleared. The backup circuit 25 detects that the power to the CPU 20 is turned off and supplies power to the RAM 21 using a backup battery. Therefore, the sales total RAM 21 effectively functions as a non-volatile memory.

Note that an output unit 26 is detachably connected to the totalizing device 11 via a connector 27. The output unit 26 is, for example, a printer unit, and a print key (not shown) in the unit 26 is used.
Alternatively, based on a print command (PR) or print and clear command (PC) generated by pressing a print clear key (not shown), the totaling device 11 calculates the total sales amount for each denomination stored in the RAM 21. The data is given to the printer unit 26 via the interface circuit 28, and the total sales amount for each denomination is printed out. Furthermore, when a print and clear command (PC) occurs, the memory of the RAM 21 is cleared after printing. The output unit 26 is not limited to a printer, but may be any other suitable device such as a magnetic recording device.
In short, any device that can transfer the contents of the RAM 21 in a portable manner will suffice.

An example of a processing program executed by the CPU 20 is shown in FIGS. 3 and 4.

In FIG. 3, when the program starts, all contents of the working area (register means) in the CPU 20 are first cleared by the "working area clear" process. Next “Equipment No.
In the "reading" process, a device number unique to the aggregation device 11 is read. This equipment number is set by an equipment number setting device (not shown) provided in the totalizing device 11, and the number set in this equipment number setting device is taken into the CPU 20 and stored. This device number is necessary to identify each vending machine when multiple vending machines are set up. Next “Initialize?”
Then, it is determined whether an initialize key (not shown) is turned on. This initialization key (not shown) is provided in the totaling device 11, and is operated by the route manager at the beginning of the sales totaling process. When the initialize key is turned on (Initialize? is YES), “Rexn←0,Rexpc
← 0” processing. “Rexn←0” is total sales amount
All memory sections Rex ₁₀ , Rex ₅₀ , and Rex ₁₀₀ of the RAM 21 are cleared. “Rexpc←0” is also RAM2
Print count storage unit Rexpc provided in 1
(not shown in Figure 1). The print count storage Rexpc stores the number of times printing has been performed in the printer unit 26 in the past. The initialize key is only turned on temporarily at the time of recording the sales aggregation process, and normally the "Initialize?" is NO.

At the next "PR?", it is determined whether a print command has been issued. If NO, move to "PC?""PC?" determines whether a print and clear command has been issued. If NO, the process moves to "DS1?" indicated by reference numeral 29. This “DS1?”
It is determined whether the digit strobe pulse DS1 corresponding to the tens digit (10 yen) is generated ("1") or not ("0"). The answer is YES when the pulse DS1 is occurring, and the answer is NO when the pulse DS1 is not occurring. If no coin is inserted and the display on the amount display 14 is "0", the pulse DS1 is not generated at all, and the NO of the "DS1?" code 29 indicates that the "equipment"
Return to "Loading No.".

When coins are inserted When coins are inserted into the vending machine, the amount of coins inserted is added and counted by the addition/subtraction counter 16 of the changer device 12, and the display on the amount display 14 increases by an amount corresponding to the amount inserted. Therefore, a digital strobe pulse DS1 is generated. As a result, the code 29 "DS1?" becomes YES, and the code 30
Move on to "DS1?". This code 30 “DS
1? ", it is on standby while the pulse DS1 is generated (YES), and when the pulse DS1 falls to "0" (NO), it moves to the next code 31 "DS1?". This code 31 “DS1?” is the amount display 1
This function works to detect that the display of 4 has become "0", and when it is NO, it starts the 20ms timer and whether 20ms has passed without pulse DS1 being generated ("20ms elapsed?" YES). Check whether or not (NO). If some value (a value of 10 yen or more) is displayed on the amount display 14, the strobe pulse DS1 is repeatedly generated as shown in FIG. 2, and the repetition period is shorter than 20 ms. Therefore, indicator 1
If 4 is displaying any value other than "0", pulse DS1 is generated again while going through the loop of NO at code 31 and NO at "20ms elapsed?" ” becomes YES.

"M ₁ ← Dsg" is the tens digit (10 yen digit) value Dsg of the displayed amount given from the encoder 23 to the CPU 20 in synchronization with the strobe pulse DS1.
is the tens place register of the currently displayed amount register Mn′
Store in M ₁ ′. Next, after waiting for the pulse DS1 to fall to "0" (waiting for "DS1?" at 32 to become NO), the process moves to the determination at "DS2?" at 33. This "DS2?" determines whether or not the strobe pulse DS2 corresponding to the hundreds digit is generated. When “DS2?” is YES, “M ₂ ′←Dsg”
Then, at the same time as the strobe pulse DS2, the hundreds' place value Dsg of the displayed amount given from the encoder 23 to the CPU 20 is stored in the hundreds' place register M ₂ ' of the current displayed amount register Mn'. If the strobe pulse DS2 does not occur (if "DS2?" at code 33 is NO), it means that there is no displayed amount of 100 or more digits, and "DS1?" at code 34 indicates that there is no displayed amount. After confirming that the strobe pulse DS1 of the order of magnitude DS1 is generated again (YES), "M ₂ '←0" and "M ₃ '←0" are processed. This process is a process for forcibly setting the contents of the hundreds register M ₂ ' and the thousands register M ₃ ' of the currently displayed amount register Mn' to zero.

On the other hand, after processing “M ₂ ′←Dsg”, pulse DS
Waiting for the signal 2 to fall to "0" (waiting for "DS2?" at 35 to become NO), the process moves on to the determination at "DS3?" at 36. This "DS3?" determines whether or not the strobe pulse DS3 corresponding to the thousands digit is generated. When "DS3?" is YES, it means that some number is displayed in the thousands place, and the value Dsg in the thousand place of the displayed amount given from the encoder 23 to the CPU 20 at the same time as this pulse DS3 is the current displayed amount. It is stored in register M ₃ ' in the thousands place of register Mn' (M ₃ '←Dsg'). However, when "DS3?" is NO, it means that the displayed amount in the thousands digit does not exist, and the "DS3?"
1? ” strobe pulse DS1 in the tens place
After confirming that it occurs again (YES),
Process “M ₃ ′←0”.

The one in Figure 3 is connected to the one in Figure 4. As described above, the current displayed amount register Mn′ (M ₁ ′, M ₂ ′,
After storing the amount currently displayed on the display 14 in _M3 '), the process moves to the determination of "Mn=Mn'?" in FIG. Here, it is determined whether the contents of the previously displayed amount register Mn and the contents of the currently displayed amount register Mn' match (YES) or (NO). At the beginning, the previous display amount register
Since the content of Mn is 0, it does not match the content of the currently displayed amount register Mn' which has been increased by the inserted coins, so (NO), the process moves to "Mn'-Mn". Here, the contents of register Mn are subtracted from the contents of register Mn′, and whether the current displayed amount has increased (Mn′>
Mn) or decreased (Mn′<Mn). At first, the current displayed amount increases as coins are inserted, so the process moves to the "Mn′>Mn" processing route. In "100 yen up?", it is determined whether the subtraction result of "Mn'-Mn" is +10 (100 yen increase),
If YES, perform the process “R ₁₀₀ ←R ₁₀₀ +1”.
The processing of “R ₁₀₀ ←R ₁₀₀ +1” is done using the 100 yen counter R ₁₀₀
Increase the content by 1 count. If "100 yen up?" is YES, that is, if the displayed amount increases by 100 yen at a time, it means that a 100 yen coin has been inserted, so the 100 yen counter R ₁₀₀ will be incremented by 1 count and 100 yen will be added. It remembers that one coin was accepted.

In the next "50 yen up?", judge whether the subtraction result of "Mn'-Mn" is +5 (50 yen increase) or not.
If YES, perform the process “R ₅₀ ←R ₅₀ +1”.
In the process of "R ₅₀ ← R ₅₀ +1", the content of the 50 yen counter R ₅₀ is incremented by 1. In the next question "10 yen up?", the subtraction result of "Mn'-Mn" is +1 (10
yen increase), and if YES, “R ₁₀ ←
R ₁₀ +1" processing is performed. In the process of "R ₁₀ ← R ₁₀ + 1", the content of the 10 yen counter R ₁₀ is incremented by 1.

In addition, if different types of coins can increase at the same time, for example, the amount that increases at one time is 60 yen (simultaneous increase of 10 yen coins and 50 yen coins), 110 (simultaneous increase of 10 yen coins and 100 yen coins), 150 yen coins. In the case of yen (simultaneous increase in 50 yen coins and 100 yen coins) or 160 yen (simultaneous increase in 10 yen, 50 yen, 100 yen coins), click the above "100 yen increase?"
According to the judgment, even if the subtraction result is +11, +15, +16,
It is treated as YES if the subtraction result is +6 or +16 in the judgment "50 yen up?", and YES if the subtraction result is +6, +11, +16 in the judgment "10 yen up?" .

In the process of "Fb←1", the coin input flag Fb is set to "1". This means that a coin is inserted,
This indicates that some amount other than 0 is now displayed on the amount display 14. After the above processing (after the denomination specific counters R ₁₀ , R ₅₀ , and R ₁₀₀ count up), the contents of the currently displayed amount register Mn' are transferred to the previously displayed amount register Mn (Mn←Mn'). Thereafter, the program jumps from FIG. 4 to FIG. 3.

Returning to FIG. 3, the processes from 30 onwards are repeated. If there is time to spare between inserting the previous coin and inserting the next coin (in other words, no additional coins have been inserted yet), the register will not be filled even if you perform the steps up to 3 in Figure 3.
The contents of Mn′ (M ₁ ′, M ₂ ′, M ₃ ′) do not change. Therefore, in that case, “Mn=Mn′?” in Figure 4 is
The answer is YES, and the decision is "Fk?". Since the sales processing flag Fk' has not yet been set, "Fk?" is NO, and the process moves to "VS?". However, since the sales start signal VS has not yet been generated, "VS?" is NO, and the system jumps again to the state shown in FIG. 3.

When additional coins are inserted, registers Mn′ (M ₁ ′, M ₂ ′,
The content of M ₃ ′) increases by the amount of additional input compared to the previous time. Therefore, “Mn=Mn′?” in Figure 4 is NO,
“Mn′−Mn” is (Mn′>Mn), and the counter (R ₁₀ , R ₅₀ ,
(R ₁₀₀ ) will be counted up by 1.

After repeating the above process and inserting coins, "Mn=Mn′?" becomes stable in the state of YES. At this time, the number of inserted coins for each denomination is stored in the denomination-specific counters R ₁₀ , R ₅₀ , and R ₁₀₀ , respectively. After inserting coins, when the purchaser operates the selection switch to purchase a product, the vendor control unit 13 generates a sales start signal VS for a certain period of time. This results in “Mn
"VS?" in the path of "=Mn'" YES becomes YES, and the sales start flag Fvs is set (Fvs
←1).

Processing at the start of sales After setting the sales start flag Fvs, the third
Jump to the figure and repeat the processing of the ``Mn=Mn''' YES route until the amount displayed on the amount display 14 changes. On the other hand, the changer device 12 (first
In FIG. 2, the sales price is subtracted from the contents of the addition/subtraction counter 16 based on the sales start signal VS. Therefore, after a while after the sales start signal VS is generated, the amount display signal given to the amount display 14 decreases by the amount of the sales price. Along with this, through the processing from to in FIG. 3, the contents of the current displayed amount register Mn' are reduced from the contents of the previous displayed amount register Mn by the amount of the selling price. Therefore, "Mn=Mn'?" in FIG. 4 is NO, "Mn'-Mn" is (Mn'<Mn), and we move on to "Fvs?". The sales start flag Fvs has been set, so click "Fvs?"
is YES, and the process moves to "Fvs←0". “Fvs.
←0'' resets the sales start flag Fvs. Thereafter, the sales processing flag Fk is reset (Fk←1) and the process moves to "Fa?". Since the end flag Fa has not been set yet, "Fa?" is NO, and the process moves to "Mn←Mn'", and the contents of the previously displayed amount register Mn are replaced by the contents of the currently displayed amount register Mn'. Ru. Therefore, the previous display amount register
The contents of Mn change to the amount of change (the amount that is obtained by subtracting the selling price from the input amount). At this time, the denomination-specific counter
No subtraction of R ₁₀ , R ₅₀ , R ₁₀₀ is performed.

When change is dispensed When change coins are dispensed, the amount displayed on the amount display 14 is decreased by the amount of the dispensed coins. At this time, the displayed amount after subtracting the change payout amount is still 0.
If not, the currently displayed amount is stored in the currently displayed amount register Mn' through the processes from to in FIG. Therefore, “Mn=Mn′” in Figure 4
is NO, “Mn′−Mn” is (Mn′<Mn),
The difference is a value corresponding to the denomination of the coin paid out. Also, since the sales start flag Fvs has already been reset, "Fvs?" is NO.
“10 yen down?”, “50 yen down?” or “100 yen down?”
Yen down? ”. If the subtraction result of "Mn'-Mn" is -1 (that is, 10 yen coin payout), "10 yen down?" is YES, and "R ₁₀ ← R ₁₀ -1"
The contents of the 10 yen counter _R10 are counted down by 1 through the process. The subtraction result of "Mn'-Mn" is -5
(In other words, to pay out a 50 yen coin), "50 yen down?" is YES, and the content of the 50 yen counter R ₅₀ is counted down by 1 by processing "R ₅₀ ← R ₅₀ -1". If the subtraction result of "Mn'-Mn" is -10 (i.e. 100 yen coin payout), "100 yen down?"
is YES, and the content of the 100 yen counter R ₁₀₀ is counted down by 1 by processing "R ₁₀₀ ← R ₁₀₀ -1". After that, the process moves to the judgment "Fa?", but since the end flag Fa has not been set yet (NO), the process moves to "Mn - Mn'", and the contents of the currently displayed amount register Mn' are transferred to the previously displayed amount register Mn. Remember. Thereafter, the same process as described above is repeated every time a change coin is paid out, and the counter (one of R ₁₀ , R ₅₀ , R ₁₀₀ ) corresponding to the paid coin is decremented by one.

When the last change coin is paid out, the amount displayed on the amount display 14 becomes 0 and the digit strobe pulses DS1 to DS3 are no longer generated.
At this time, the contents of the previously displayed amount register Mn are the amount for one last coin paid out (10 yen, 50 yen, or 100 yen). Now, strobe pulse DS1
is no longer generated, the judgment "DS1?" at numerals 30 and 31 in FIG. 3 is always NO, and
The time 20ms of the 20ms timer elapses. Therefore,
“Has 20ms passed?” Move to the YES processing path. First, confirm that the coin input flag Fb is set (YES) in "Fb?", and set the contents of the current displayed amount register Mn' to 0 in the process of "Mn'←0".
Reset to . Thereafter, the end flag Fa is set (Fa←1), and the program jumps from FIG. 3 to FIG. 4, ie, "Mn'-Mn". At this time, as mentioned above, the previous display amount register Mn stores the amount for the last coin paid out, so Mn'< Mn, and the "10 yen" is sent via "Fvs?" NO. ``Down?'', ``50 yen down?'', or ``100 yen down?''. In this way, the counter (one of R ₁₀ , R ₅₀ , R ₁₀₀ ) corresponding to the last coin denomination paid out is counted down by one. The next "Fa?" is determined to be YES because the end flag Fa is set, and each memory section Rex ₁₀ of the sales total RAM 21 is
Rex ₅₀ , Rex ₁₀₀ contents with denomination counter R ₁₀ ,
The contents of R ₅₀ and R ₁₀₀ are added.

At this time, each counter R ₁₀ , R ₅₀ , R ₁₀₀ contains the value obtained by subtracting the number of change coins of each denomination from the number of coins input for each denomination, that is, the number of coins of each denomination accepted as the sales price (sales revenue). remembered.
The contents of the 10 yen counter _R10 are added to the old contents of the storage unit _Rex10 , and the addition result is newly stored in the storage unit _Rex10 ( _Rex10 ← _Rex10 + _R10 ). The same applies to the storage unit Rex ₅₀ for 50 yen and the storage unit Rex ₁₀₀ for 100 yen (Rex ₅₀ ←Rex ₅₀ +R ₅₀ , Rex ₁₀₀ ←Rex ₁₀₀
+ _R100 ). In this way, the number of coins corresponding to the sales of each denomination is accumulated in each of the storage units Rex ₁₀ , Rex ₅₀ , and Rex ₁₀₀ of the sales total RAM 21 . After that, the contents of the denomination-specific counters R ₁₀ , R ₅₀ , and R ₁₀₀ are all cleared (Rn←0), and the previously displayed amount register Mn
The contents of are also cleared (Mn←0). Furthermore, after resetting each flag Fa, Fb, Fk (Fa←0,
Fb←0, Fk←0), jumps from Fig. 4 to Fig. 3.

When there is no change If the displayed amount becomes 0 when the sales price is subtracted based on the sales start signal VS, there is no change. In this case, the process goes from NO at 31 in FIG. 3 to YES at ``20 ms elapsed?'', processes ``Mn'←0'' and ``Fa←1'', and jumps to the state shown in FIG. 4. Then, "Fvs?" in Fig. 4 is YES, and after processing "Fvs←0" and "Fk←1",
Move on to “Fa?” Since "Fa?" is YES, the contents of the counters R ₁₀ , R ₅₀ , R ₁₀₀ are stored in the memory section Rex ₁₀ ,
Immediately move on to the process of adding to Rex ₅₀ and Rex ₁₀₀ . Therefore, the process ends without going through the subtraction process route for the number of change payouts at counters R ₁₀ , R ₅₀ , and R ₁₀₀ .

In the case of cancellation without making a sale If the subscription is canceled before a sale is made, the entire amount of money put in is returned in the vending machine main body 10 without generating the sales start signal VS. The displayed amount will gradually decrease as the inserted coins are returned and withdrawn.
"Mn'-Mn" in FIG. 4 becomes "Mn<Mn".
However, since the sales start flag Fvs is not set, it immediately goes to the "10 yen down?" route without going through the "Fvs←0" and "Fk←1" routes, and the denomination counters R ₁₀ , R ₅₀ , All the number of coins inserted will be subtracted from the contents of R ₁₀₀ .

Print processing Print processing is performed during standby mode. In other words, when jumping to the point shown in FIG. 3 after completing a series of aggregation processes, it is determined whether a print command PR (PR?) or a print and clear command PC (PC?) has been generated. will be done. "PR?" If YES, the process returns after performing the predetermined "print processing.""PC?" If YES, after the specified "print processing", "Rexn←0"
The storage section in the sales total RAM 21 is
Clear all Rex ₁₀ , Rex ₅₀ , and Rex ₁₀₀ , then return. In "print processing", for example, "equipment number", past "number of prints", and "number of 10 yen coins sold" stored in the storage unit Rex ₁₀ .
and its "amount", the "50 yen coin sales number" and its "amount" stored in the memory section Rex ₅₀ , the memory section
“Number of 100 yen coins sold” stored in Rex ₁₀₀
The "amount" and "total sales amount" are printed out.

In the above example, the coin denominations are 10 yen and 50 yen.
Although yen and 100 yen are shown as examples, it is of course not limited to these.

In the above embodiment, in order to ignore the decrease in the amount display signal due to sales price subtraction and subtract only the true number of coins to be paid out using the denomination-specific counters R ₁₀ , R ₅₀ , and R ₁₀₀ , the vendor control unit 13 Although the sales start signal VS supplied to the changer device 12 is used, it is not limited to this, and is "a signal indicating that each column on the vendor control unit side is ready to dispense products."
Alternatively, "a signal indicating that the selling price has been subtracted" or "a signal indicating that the coin (change or return coin) is ready to be paid out (for example, a settlement signal)" etc. In short, the amount signal on the amount display 14 or the addition/subtraction counter 16 Any signal that can distinguish whether the decrease is due to sales price subtraction or coin dispensing may be used, and for convenience, these signals will be collectively referred to as sales start signals.

<Effects of the Invention> As explained above, according to the present invention, when the amount display data is used for aggregation processing, the decrease in the amount display data immediately after the sales start signal is generated (that is, the decrease due to sales price subtraction) is ignored. As a result, it is now possible to reliably grasp the amount of coins in and out of the vending machine based on changes in the amount display data, and it is now possible to aggregate the amount received (sales amount) using the amount display data. becomes. Furthermore, since the inflow and outflow of each coin can be determined from the amount of change in amount display data, it is possible to easily perform aggregation processing by denomination.
