Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a control device for a vending machine, and particularly to a coin storage main device in which stored coins are automatically replenished according to inserted coins, and a coin storage main device in which stored coins are manually refilled. The present invention relates to a control device for a vending machine having a coin storage auxiliary device to be replenished, in which the coins stored in the coin storage main device and the coin storage auxiliary device are utilized as effectively as possible.

[Conventional technology]

Conventionally, in vending machines, in order to reliably prevent unforeseen situations where change cannot be paid to the purchaser, the amount of change stored in vending machines is set to a predetermined value (this predetermined value is usually the maximum amount of change). The amount is
For example, if the amount is below (for example, 90 yen), an "out of change" message is displayed and all subsequent sales operations or sales operations that require change are prohibited. The conventional method for detecting "out of change" is to place a coin detection switch (empty switch) at a predetermined position of the change coin storage tube (usually near the position corresponding to the maximum amount of change), and to detect the change based on the output of this switch. ``Out of change'' was detected.

On the other hand, one of the important issues to improve the sales efficiency of vending machines is to prevent the occurrence of "out of change" as much as possible and to keep the vending machines always in a state where they can sell. be. This problem has become particularly important in the recently developed vending machines that handle a large amount of money in a single purchase (sales). In other words, in this new type of vending machine, the purchaser's choice is made in a single purchase from the time the purchaser first inserts a coin to the time he or she presses the checkout button (switch). They are structured so that a plurality of products can be sold continuously, and therefore the total sales price tends to be large, and accordingly, the total amount of coins inserted tends to be large. The larger the amount of money handled, the greater the possibility that the amount of change paid or the amount returned when a purchase is canceled will be large. Therefore, if this point is not taken into account, there is a risk that "out of change" situations will occur frequently.

Therefore, in order to secure a sufficient amount of coins for change, a method has recently been proposed in which a coin storage auxiliary device (hereinafter referred to as an auxiliary tube) is provided exclusively for coin dispensing (for example, Japanese Patent Laid-Open No. 41598/1983). Originally, the main coin storage device (hereinafter referred to as the main tube) that was designed to automatically replenish coins inserted by the purchaser was used as a coin storage device for change or dispensing in vending machines. was used. In addition to this main tube, an auxiliary tube dedicated to coin dispensing, which is manually refilled with coins by the vending machine manager, is provided in order to ensure a sufficient amount of coins for change.

[Problems to be Solved by the Invention] The problem here is a method for detecting "out of change" regarding the main tube and the auxiliary tube, and no effective means regarding this point has yet been proposed. For example, the aforementioned Japanese Patent Application Publication No. 51-41598
"Empty switch" as shown in the publication
It is conceivable to provide each main tube and each auxiliary tube with ``empty switches'', but as the number of main tubes and auxiliary tubes increases, the number of "empty switches" increases, which not only increases the cost, but also increases the cost. The large number of switches occupies a large amount of space for installing the switches, resulting in an increase in the size of the coin accepting device of the vending machine, making it unsuitable for practical use. Furthermore, if an empty switch is installed in each coin storage tube as described above, when the amount of stored coins falls below the position of each switch (generally the position corresponding to the maximum amount of change), coins will not be dispensed from each tube. As a result, vending machines that require change when less than a predetermined amount of coins are left in each tube are completely prohibited. The remaining number of coins below the specified amount may amount to a considerable amount (the amount that can be paid out as change) when the main tube and the auxiliary tube are combined, and the efficiency of prohibiting the sale of coins even though change can be paid out. It can also lead to bad situations.

Another problem that arises when using an auxiliary tube exclusively for dispensing coins is at what point should the tube used for dispensing coins be switched from the main tube to the auxiliary tube, or from the auxiliary tube to the main tube? ,
This is a problem with switching control of the current payout tube. As a conventional technique related to this point, a method has been proposed in which a switch for detecting the switching position is further provided on the main tube side in addition to the empty switch. When the number of coins stored in the main tube becomes less than the position of the changeover position detection switch, the switch is turned off and the tube used for dispensing is switched to the auxiliary tube. However, this method has the disadvantage that a space is required for installing the switch for detecting the switching position, and also has the disadvantage that as the number of tubes increases, the number of switches for detecting the switching position increases accordingly.

The present invention consists of a main tube (coin storage main device) in which stored coins are automatically replenished according to inserted coins, and an auxiliary tube (coin storage auxiliary device) in which coins are manually replenished.
In a vending machine with
It is an object of the present invention to provide a control device for a vending machine that minimizes the probability of occurrence of an "out of change" condition.

[Means to solve the problem]

According to the present invention, as shown in FIG. 5, the coin storage main device automatically replenishes the stored coins according to the inserted coins, the coin storage auxiliary device manually replenishes the stored coins, and the coin storage main device and a dispensing device switching means for switching either one of the coin storage auxiliary devices as a coin dispensing device, the automatic vending machine control device comprising: an automatic supply coin detection means for detecting coins automatically supplied to the coin storage main device; , a dispensed coin detection means for detecting coins dispensed from the coin storage main device; and an amount of coins detected by the automatic supply coin detection means and an amount of coins detected by the dispensed coin detection means. a storage amount counting means for calculating the amount of stored coins in the main coin storage device by subtracting and counting; out-of-change detection means for detecting out-of-change; and a coin storage auxiliary device for detecting when a coin is not dispensed from the coin storage auxiliary device even though a coin dispensing operation from the coin storage auxiliary device has been performed. an apparatus for coin out-of-coin detection means; when the out-of-change detection means detects that change is out, the coin is dispensed from the coin storage auxiliary device instead of the storage main device; and coin dispensing control means for controlling the dispensing device switching means stage to switch from the coin storage auxiliary device to the coin storage main device and dispense coins when a coin shortage from the auxiliary device is detected. Ru.

[Effect]

Coins are first dispensed from the coin storage main device. When the amount of coins stored in the main coin storage device reaches a predetermined value that is at least larger than the amount that makes change dispensing impossible, coins are dispensed from the coin storage auxiliary device instead of the main coin storage device. When the coin storage auxiliary device becomes empty due to the coin dispensing from the coin storage auxiliary device, that is, when the coins are not dispensed from the coin storage auxiliary device even though the coin dispensing operation is performed, the coins are only stored in the coin storage main device. pay out. At this point, when the amount of stored coins calculated by the storage amount counting means reaches an amount that makes it impossible to pay out the remaining fish, the remaining fish is detected to be out. In other words, the situation of running out of coins does not occur until the coin storage auxiliary device is completely empty. This allows the coins in the main coin storage device and the auxiliary coin storage device to be utilized to the maximum extent possible. Moreover, the coin storage main device and the coin storage auxiliary device do not require means for directly detecting the amount of stored coins.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

Fig. 1 schematically shows the flow path of coins in the mechanism of the coin accepting device of a vending machine according to the present invention. Assume and explain. First, the coins inserted through the coin slot 1 are inspected for genuine, counterfeit, and denomination by the coin detector 2.Based on the inspection results, the sorting mechanism 3 sends the counterfeit coins to the return passage 4, and the genuine 100 yen coins to the return passage 4.

For convenience, this tube 9 will be referred to as a "D tube." The A tube 6, the B tube 7, and the C tube 8 are preliminarily installed in a standard type coin receiving device, and the D tube 9 can be added as an option. A plurality of optional auxiliary tubes 9 can be provided in addition to the D tube as long as the mounting space allows. Further, as described above, the optional auxiliary tube 9 is not limited to a cylindrical one, but may be a hopper type. In addition, the optional auxiliary tube (including D tube 9) can be separated from the main body of the coin receiving device as indicated by a dashed line 10, and when separated, the D tube detachable memory described later will be used. Set the flip-flop 20 (FIG. 4).

At a predetermined position of the 10 yen coin main tube (A tube) 6 (for example, at a height of 9 coins), the above-mentioned "switch for guaranteeing coin detection during power outage" (A tube empty detection device) 36 is installed. The coin dispensing mechanisms 12 of the A tube, B tube, and C tube are connected to the first coin dispensing motor _M01.

One rotation of the motors M ₀₁ and M ₀₂ required for dispensing the coins is guaranteed.

Coins dispensed from each of the tubes 6 to 9 are guided to the coin dispensing passage 14, and actuate a dispensing coin detection switch 150 (described later) provided therein.

The detailed circuit of the vending machine control device according to the present invention applied to the coin accepting device having the configuration shown in FIG. 1 is as shown in FIGS. 3 and 4. To facilitate understanding of circuit operation,
FIG. 2 shows a flowchart of an example of the payout control method. The flowchart in FIG. 2 essentially corresponds to the explanation of the payout tube switching control in the general explanation of the present invention described in the first half of this specification, so it will be briefly explained here.

The control example shown in Fig. 2 uses C tube 8 as an auxiliary tube for 50 yen coins, and D tube 9.
This is an example of using it as an auxiliary tube for a 10 yen coin.

In FIG. 2, "START" indicates that the payment button has been pressed to request the return of inserted coins or change.

"R _B ≠ 0" represents the condition that the counted content R _B of the later-described 50 yen coin counter 30 corresponding to the medium denomination input coin counting circuit is not 0.

"YES" means "NO" if the condition is met
shows the control system when the conditions are not met.

"R _A ≠ 0" means that the 10 yen coin counter 29 (the third
This represents the condition that the count content R _A in Figure) is not 0.

"R _B ≠ 0" The yes system is a control system for dispensing 50 yen coins from the main tube (B tube) 7 or the auxiliary tube (C tube) 8, "R _A ≠ 0"
The YES system is a control system for dispensing 10 yen coins from the main tube (A tube) 6 or the auxiliary tube (D tube) 9.

"F" is a flip-flop (flip-flop 173 described later in FIG. 4) that is set when it is necessary to transfer and pay out the amount to be paid out in medium denomination coins (50 yen) to minimum denomination coins (10 yen). This indicates the condition of whether or not it is set, and if it is set, it is ``YES'', and if it is reset, it is ``NO''.

"F set" refers to the flip-flop 173 mentioned above.
"F reset" represents the operation of resetting the flip-flop 173.

"Sale" represents the condition that a sale is made to a purchaser. When this is "NO", the total amount of coins inserted is returned without any sales being made. In FIG. 3, when a sales storage flip-flop 70, which will be described later, is set, "Sale" becomes "YES".

"R _BN = 0" is the 50 yen coin storage amount counter 3 described later, which corresponds to the medium denomination input coin counting circuit described above.
3 (FIG. 3) represents the condition that the count content _RBN is 0.

"R _AN =0" represents the condition that the counted content R _AN of the later-described 10 yen coin storage amount counter 32 (FIG. 3), which corresponds to the above-mentioned minimum denomination input coin counting circuit, is 0.

"" represents the condition that the C tube 8 is not blank.

"B tube", "C tube", "A tube",
"D tube" means B tube 7, respectively.
This represents the operation of dispensing coins from the C tube 8, the A tube 6, and the D tube 9.

"Blank detection" next to the dispensing operation block for each tube indicates that it has been detected that the tube has become blank. This blank detection method detects when a coin is not dispensed even though the coin dispensing motors M ₀₁ and M ₀₂ are driven as described above.

"CE set" represents the operation of blank storage of the C tube. This is to set a flip-flop 19 (FIG. 4) for holding a C tube blank signal, which will be described later.

"CE reset" refers to the operation of resetting the blank signal retention of the C tube. In other words, the state is such that "CE" becomes YES.

As mentioned above, "transfer" means a state in which the amount to be paid out in medium denomination coins (50 yen coins) is transferred and paid out in minimum denomination coins (10 yen coins).

"Lock" means that the coin to be dispensed is caught in the coin dispensing mechanism 12, and the motor M ₀₁
This condition indicates that the rotation is not tight.

"Rotate the motor three times" means to repeat the forward and reverse rotation of the motor about three times when "lock" is YES, as described above.

"Unlocked" indicates that the "locked" state has been resolved as a result of "turning the motor three times."

``'' represents the condition that the D-tube (optional auxiliary tube or hopper type auxiliary storage) is not separated from the main body of the coin acceptor. The state in which the D-tube disconnection signal holding flip-flop 20 (FIG. 4), which will be described later, is reset is "YES".

"END" indicates that coin dispensing has ended.

"STOP" indicates that the vending machine is deemed to be malfunctioning and the operation of the vending machine is stopped.

In the flowchart of FIG. 2, there is no system for "turning the motor three times" when "locking" the C tube and the D tube, but it may be provided if necessary.

In addition, both C tube 8 and D tube 9 are 10
A flowchart for the case where the tube is used as an auxiliary tube for yen coins is not particularly shown, but it can be easily created based on the matters explained above and FIG. 2.

A detailed circuit diagram of an embodiment of a control device for a vending machine according to the present invention is shown separately in FIG. 3 and FIG. 4 for convenience of drawing. The circuits of FIGS. 3 and 4 are line 18,
111, 116, 125, 176, 177 and 1
They are connected to each other via 96 and assembled into an integrated circuit. In practice, the circuits shown in FIGS. 3 and 4 have portions that are connected to each other by more wiring, but these are omitted since they do not pose a particular problem for the explanation. Most of the circuit parts shown in FIG. 3 are related to the "money collection" control device of the present invention. Moreover, the circuit portion shown in FIG. 4 is mostly related to the "dispensing tube switching" control device of the present invention. However, as mentioned above, the two figures are separated for convenience, so there is no clear division, and there is no purpose of dividing them into bright and dark functions.

When the aforementioned coin detector 2 detects the insertion of a 10 yen coin, one 10 yen detection pulse P ₁₀ is sent to the terminal.
When the insertion of a 50 yen specie coin is detected, one 50 yen detection pulse P ₅₀ is applied to the terminal T 2, and when the insertion of a 100 yen specie coin is detected, one pulse P ₅₀ is applied to the terminal T ₂ . 100
A circle detection pulse P ₁₀₀ is applied to terminal T ₃ .

10 yen, 50 yen added to this T ₁ , T ₂ , T ₃ ,
Pulse signals corresponding to the number of 100 yen coins (regular coins) inserted are applied to AND circuits 21, 22, and 23, respectively.

A signal on line 24 (described in detail later) indicating prohibition of coin insertion is applied to the other input terminals of AND circuits 21, 22, and 23 via an inverter 25. The output of the coin acceptance restriction circuit 43A is sent to the AND circuit 22, and the output of the 50 yen coin acceptance restriction circuit 43B is sent to the AND circuit 2.
The output of the 100 yen coin acceptance restriction circuit 43C is added to each line 3, and now the signal on line 24 is "0", and each coin acceptance restriction circuit 43A, 43B,
Assuming that the output of 43C is "1", the AND circuits 21, 22, and 23 are in an open state, and the terminal
The pulse signals applied to T ₁ , T ₂ and T ₃ are passed through OR circuits 26, 27 and 28 to the 10 yen coin counter 2.
9. Add to counter 30 for 50 yen coins and counter 31 for 100 yen coins.

The counter 29 for 10 yen coins, the counter 30 for 50 yen coins, and the counter 31 for 100 yen coins are connected to terminals T ₁ ,
Count the 10 yen detection pulse P ₁₀ , 50 yen detection pulse P ₅₀ , and 100 yen detection pulse P ₁₀₀ from T ₂ and T ₃ , and based on this count, calculate the number or amount of coins inserted for 10 yen, 50 yen,
Count by denomination of 100 yen.

For example, there are three 10 yen coins, one 50 yen coin,
When two 100 yen coins are inserted, the 10 yen coin counter 29 becomes 30, and the 50 yen coin counter 30 becomes 5.
The counter 31 for 0 and 100 yen coins counts 200.

10 from terminal T ₁ via AND circuit 21
The yen detection pulse P ₁₀ and the 50 yen detection pulse P ₅₀ from the terminal T ₂ via the AND circuit 22 are supplied to the 10 yen coin storage amount counter 32 and the 50 yen coin storage amount counter 33, respectively.
added to.

The 10 yen coin storage amount counter 32 and the 50 yen coin storage amount counter are the coin counters 29, 30,
31 counts the amount of coins inserted and sets the count value to 0 every time a sales operation is completed, whereas the number of 10 yen and 50 yen coins inserted is continuously added, and the number of coins paid out is continuously added. It is calculated by accumulating the difference between the number of coins inserted and the number of coins dispensed based on the number of 10 yen and 50 yen coins held at the time the vending machine starts using the machine.

The 10 yen coin storage amount counter 32 and the 50 yen coin storage amount counter 33 detect when the number of 10 yen and 50 yen coins held for exchange is less than the sufficient number to pay out change (this is called empty). used for.

That is, the count values of the storage amount counters 32 and 33 are added to the empty detection circuit 34, and based on the count values of the storage amount counters 32 and 33, 10
When it is detected that the number of yen and 50 yen coins held is 4 10 yen coins, 1 50 yen coin, or 9 10 yen coins or less, a signal “1” is sent to the empty processing device 35.
Add to.

The empty processing device 35 is a display section that displays an out-of-change message when a signal "1" is applied to it. When the empty processing device 35 displays an out-of-change display, the vending machine performs a vending operation only when the input amount matches the sales setting amount. Let's do it.

In this way, the 10 yen coin storage counter 32,
Empty change coins are detected based on the count value of the 50 yen coin storage counter 33, but if the vending machine is turned off due to a power outage, for example, the storage amount counters 32 and 33 are cleared to 0,
When electricity is turned on again, empty change coins cannot be accurately detected.

To prevent this, the storage amount counter 3
2 and 33, an empty detection device 36 is provided which directly detects the number of remaining coins in the 100 yen coin main tube in addition to empty detection.

For example, the empty detection device 36 may include a coil wound around a predetermined position of the 10 yen coin main tube 6 and an empty detection device that detects an empty state based on a change in the inductance of the coil, or a limit switch arranged at a predetermined position of the 10 yen coin main tube 6. This circuit consists of a device that detects empty status from the on/off of this limit switch, etc., and when the number of coins held in the 10 yen coin main tube 6 becomes less than the minimum number required for dispensing change, a signal "1" is output to the AND circuit 37. Add to.

The other input terminal of the AND circuit 37 is applied with a signal from a comparison circuit 38 which outputs "1" when the counts of the coin counters 29, 30, 31 are all 0.

Therefore, the AND circuit 37 is opened only when the count values of the coin counters 29, 30, and 31 are all 0, and the signal "1" is applied to the empty processing device 35 via the empty detection circuit 34, and is processed appropriately in the same manner as described above. Empty processing is performed.

Here, the signal from the empty detection device 36 is sent to the coin counter 2 by the AND circuit 37.
The reason why it is applied to the empty detection circuit 34 only when the count values 9, 30, and 31 are all 0, that is, when the vending machine is in standby mode, and not when the vending machine is operating is that the automatic This is to eliminate the inconvenience that the empty processing device 36 operates while the vending machine is operating, for example, change is being dispensed and the change is not completely dispensed.

In addition, when the count values of the coin counters 29, 30, and 31 are all 0, a product selection button (not shown) is pressed.
It is configured such that insertion of coins is prevented when is pressed.

When the product selection button is pressed, a product selection signal PU is applied to the AND circuit 39 via the terminal _T5 .

The other input terminal of the AND circuit 39 is supplied with a signal from a comparison circuit 38 which outputs a signal "1" when the counts of the coin counters 29, 30, 31 are all 0.

Therefore, when the product selection button is pressed when the count values of the coin counters 29, 30, and 31 are all 0, the output of the AND circuit 39 becomes "1", and this signal "1" is sent to the OR circuit 40 and the OR circuit. 41, and is added to the coin input rejection device 42 via line 24.

The coin insertion refusal device 42 prevents the insertion of coins when a signal "1" is applied. For example, a pin protrudes from the coin insertion slot to prevent the insertion of coins, or even if the coin is inserted, the inserted coin is not a coin. It is configured so that it is not detected by the detector and is returned directly to the return slot.

In this way, when the count values of the coin counters 29, 30, and 31 are "0", coins cannot be inserted while the product selection button is pressed.

In addition, if a large number of coins of one type are inserted in a single sale, or if the total amount of coins inserted is large, the number of coins held may become unbalanced and there may be a shortage of change. This is not desirable as it may act like a money changer.

For this reason, each coin (10 yen, 50 yen) in one sale
The maximum amount of input (100 yen) and the maximum total amount of coins inserted are limited.

That is, the outputs of the coin counters 29, 30, and 31 that count the amount of inserted coins by denomination are sent to the upper limit detection unit 43's 10 yen coin acceptance restriction circuit 43A, 50 yen coin acceptance restriction circuit 43B, and 100 yen coin acceptance restriction circuit. In addition to 43C, each coin counter 29, 3
The content of 0 and 31 is the limit value (for example, a 10 yen coin is 320
yen, 50 yen coins are 800 yen, 100 yen coins are 700 yen), each acceptance restriction circuit 43A, 43B,
The input coins are rejected for each type of coin by the signal "0" sent from 43C. The outputs of the coin counters 29, 30, and 31 are also applied to the total input amount upper limit limit circuit 43D, and a signal "1" is sent out when the total input amount reaches a set upper limit value (set as appropriate). ”, the coin acceptance refusal device 42 is operated and the subsequent acceptance of all inserted coins is prohibited.

Coin counters 29, 30, and 31 that separately count the amounts of 10 yen coins, 50 yen coins, and 100 yen coins.
The output of is applied to a comparator circuit 44.

On the other hand, the selling price of the product is determined by the selling price setting circuit 45.
This is serially processed by the serialization register 46 and applied to the comparison circuit 44.
The sales price setting circuit 45 is configured to set a signal (binary number) corresponding to the sales price by, for example, turning on a plurality of switches as appropriate.
In a vending machine that sells multiple types of products, the sales price setting circuit 45 sets multiple sales prices corresponding to each product, and the sales price of the product selected by pressing a product selection button (not shown) is set by the sales price setting circuit 45. Although it is configured to output only the following information, it will not be described in detail here.

The comparison circuit 44 includes coin counters 29, 30,
31 count values R _A , R _B , and R _C (=R _A +R _B +R _C ), and the sales set price R _SP from the serialization register 45 are compared.

Based on this comparison, the total input amount K and the sales set price
When R _SP are equal (K=R _SP , a signal "1" is output to the line 47, and this signal is applied to the AND circuit 49 via the OR circuit 48.

Also, when the total input amount K is larger than the sales set price R _SP (K>R _SP ), the signal “1” is sent to the line 50.
This signal is applied to the AND circuit 51.
A signal obtained by inverting the output of the empty detection circuit 34 is applied to the other input terminal of the AND circuit 51. It is opened when enough coins are held and applies the signal on line 50, like the signal on line 47, to AND circuit 49 via OR circuit 48.

The other input terminal of the AND circuit 49 is connected to the line 5.
2 and line 87 (both of which are "1" when the vending machine is in vending operation and will be described in detail later) are added to the vending machine.

Therefore, if the vending machine is not in the vending operation, the AND circuit 49 is open and the signal "1" is output as the vending signal.
Bender part (not shown) through terminal T ₇ as V _e
Send to.

The vendor department starts controlling the sending of sales products based on the sales signal V _e , and at the same time sends a sales start signal S _e
is added to terminal T ₄ .

Note that the configuration of the vendor section is not directly related to the present invention and will not be described in detail here.

The sales start signal S _e (signal “1”) applied to the terminal T ₄ is applied to the timer 54 via the OR circuit 53 .

The timer 54 has a predetermined delay time _t0 , and is configured such that when a signal "1" is applied, the output rises from " ₀ " to "1" after time t0 has elapsed.
The output of this timer 54 is applied to an AND circuit 55.

The other input terminal of the AND circuit 55 has the terminal
Since the sales start signal S _e from T ₄ is added,
If the sales start signal S _e applied to the terminal T ₄ is held longer than the delay time t ₀ of the timer 54, the AND condition of the AND circuit 55 is satisfied, and the signal "1" is added to the flip-flop 56 for holding the sales start signal, and the sales start. The signal holding flip-flop 56 is set, and at the same time, the signal "1" is applied to the delay flip-flop 58 via the OR circuit 57, the delay flip-flop 58 is set, and the set output "1" is sent again via the OR circuit 53 to the timer. 54 as well as a timer 54.

Output of flip-flop 56 for holding sales start signal, flip-flop 58 for delay, and timer 54
The output of is applied to an AND circuit 59.

The AND circuit 59 includes the flip-flop 56,
When the output of 58 and the delay operation of timer 54 are completed, that is, when the sales start signal S _e is confirmed, the AND condition is established and a signal "1" is applied to the AND circuit 60.

The other input terminal of the AND circuit 60 is a product selection signal P _U (signal “1”) indicating that the product selection button is pressed.
is applied via terminal _T5 .

Therefore, the AND circuit 60 receives the sales start signal S _e
is opened when confirmed, and a signal "1" is added to the product selection memory 61.

A product selection memory 61 receives a signal indicating the product for sale from the serialization register 46 via a line 62 and stores which product has been selected.

Incidentally, the desired product may not be selected in the product selection memory 61 even after a predetermined period of time (the time required for sending out the product) has elapsed after the flip-flop 56 for holding the sales start signal is set, that is, after confirmation of the sales start signal S _e . If a signal "1" indicating that a problem has occurred is not stored, this means that a failure has occurred in one of them. Therefore, at this time, the operation of the vending machine is stopped.

This operation is performed as follows. The set output "1" of the flip-flop 56 for holding the sales start signal is applied to the timer 63. The timer 63 has the same configuration as the timer 54, and has a delay time t ₁
(sufficient time to complete the normal delivery operation of the product), and when a signal "1" is applied, it rises to " ₁ " after time t1 has elapsed.

The output of this timer 63 is applied to an AND circuit 64.

A signal obtained by inverting the output of the product selection memory 61 is applied to the other input terminal of the AND circuit 64.

Therefore, if the signal "1" is not stored in the product selection memory 61 after the completion of the delay operation of the timer 63, the AND condition of the AND circuit 64 is satisfied, and the signal "1" is applied to the stop circuit 65 to stop the operation of the vending machine. At the same time, a signal "1" is applied to the coin acceptance refusal device 42 via the OR circuit 41 to prevent coin insertion.

If the flip-flop 56 for holding the sales start signal is set in this way and the signal "1" indicating that the product has been selected is not stored in the product selection memory 61 by the time the timer 63 ends, the vending machine will not operate. However, if the vending machine operates normally, a signal "1" indicating the selection of the product is stored in the product selection memory 61 before the operation of the timer 63 ends, and a product sending signal S indicating the completion of sending out the product is stored. ₀ (signal "1") is applied to the AND circuit 66 via the terminal _T6 .

The sales start signal S _e from the terminal T ₄ and the output signal of the flip-flop 56 for holding the sales start signal are applied to other input terminals of the AND circuit 66 via an OR circuit 67 .

Therefore, the AND circuit 66 is opened when the sales start signal S _e is applied to the terminal T ₄ or when the product sending signal S ₀ is applied when the flip-flop 56 for holding the sales start signal is set, and outputs the signal "1" to the product. This is set in addition to the flip-flop 68 for holding the sending signal.

This product flip-flop 68 for holding the sending signal
, the output of the AND circuit 59 , and the output of the product selection memory 61 are applied to an AND circuit 69 .

A flip-flop 68 for holding a product sending signal is set in the AND circuit 69.
When the output is "1" and "1" is stored in the product selection memory 61, that is, the sales operation is started by inserting a proper coin, the selection of the product is performed reliably, and the delivery of the product is completed. When this happens, the AND condition is satisfied and a signal "1" is output.

The output signal "1" of the AND circuit 69 is applied to a sales storage flip-flop 70 to set it.

Further, this output signal “1” is output from the collection command circuit 71.
It is added to the AND circuit 72 and the AND circuit 73 to start the collection operation (described in detail later).

When the settlement button (not shown) is pressed, the settlement signal MN is applied to the other input terminal of the AND circuit 73, and a signal from the flip-flop ₇₄ for holding the settlement signal is applied and set. The signal from the flip-flop 74 for holding the adjustment signal is inverted and applied to the other input terminal of the AND circuit 72.

Therefore, when the output of the AND circuit 69 becomes "1", if the flip-flop 74 for holding the settlement signal is set by pressing the settlement button, the AND condition of the AND circuit 73 is satisfied and the signal becomes "1". is applied to the change payout command circuit 75 via the OR circuit 740, and commands a change payout operation (described in detail later).

Further, when the output of the AND circuit 69 becomes "1", if the settlement button is not pressed and the flip-flop 74 for holding the settlement signal is not set, the AND condition of the AND circuit 72 is satisfied.
The signal "1" is passed through the OR circuit 76 to the product selection memory 61 and the flip-flop 6 for holding the product sending signal.
8. Flip-flop 56 for holding sales start signal;
In addition to the reset terminals of each of the delay flip-flops 58, these are reset in preparation for the next vending operation in the vending sequence.

Incidentally, even though the flip-flop 56 for holding the sales start signal and the flip-flop 58 for delaying are set, the product sending signal _S0 is not applied to the terminal _T6 until the delay operation of the timer 63 ends, and the product sending signal is held. flip-flop 68
If it is not set, it means that the product was not sent out, so if the checkout button is pressed, a refund or change is paid, and if the checkout button is not pressed, the product selection memory 6 is
1. Flip-flops 56, 58, 70, and 74 must be reset to prepare for the next vending operation. This case will be explained. First, the payment button is pressed and the flip-flop 74 for holding the payment signal is pressed.
Suppose that is set.

The output of the flip-flop 74 for holding the settlement signal, the output of the timer 63, the output of the AND circuit 59, and the output of the product selection memory 61 are connected to the AND circuit 7.
Added to 7.

The AND circuit 77 includes a sales start signal holding flip-flop 56 and a delay flip-flop 5.
8 is set, the AND condition of the AND circuit 59 is satisfied, and "1" is stored in the product selection memory 61.
Moreover, when the delay operation of the timer 63 ends, the AND condition is satisfied and a signal "1" is applied to the AND circuit 79 and the AND circuit 80 via the OR circuit 78.

The AND circuit 80 has the output of the sales storage flip-flop 70 applied thereto, and the AND circuit 79 has the inverted output of the sales storage flip-flop 70 applied thereto.

By the way, the sales memory flip-flop 70 is set when a sales operation is performed even once, and is reset when the payment button is pressed and the payment operation (change change, refund) is completely completed. If no sales operation has been performed, the sales memory flip-flop 70 has not been set, and the AND condition of the AND circuit 79 is satisfied, and a signal "1" is applied to the refund command circuit 81, and the coins inserted are stored in the flip-flop 70. Start a return operation (described in detail later) to return the full amount.

Further, if the sales operation is performed at least once and the sales storage flip-flop 70 is set, the AND condition of the AND circuit 80 is satisfied.

Therefore, a signal "1" is applied to the change dispensing command circuit 75 via the OR circuit 740 to start dispensing change.

Next, assume that the settlement button is not pressed and the flip-flop 74 for holding the settlement signal is not set.

The output of the flip-flop 74 for holding the settlement signal and the sales start signal S _e from the terminal T ₄ are applied to the NOR circuit 82 .

The NOR circuit 82 is configured such that the flip-flop 74 for holding the settlement signal is not set and the terminal
When the signal from T ₄ is “0” (sales start signal S _e
is not added) signal “1” to AND circuit 8
Add to 3.

The other input terminal of the AND circuit 83 is connected to the timer 6.
3, the output of the AND circuit 59, and the output of the product selection memory 61 are added.

Therefore, even though the sales start signal S _e has been confirmed and the signal "1" has been stored in the product selection memory 61, the product sending signal is not added until the delay time of the timer 63 ends, and the AND circuit 69 The condition is not met and the memory 61 and flip-flop 5
When 6, 58, and 74 are not reset, the AND condition of AND circuit 83 is satisfied, and the signal "1" is applied to the reset terminals of memory 61 and flip-flops 56, 58, 74, and 68 via OR circuit 76, and these are Reset and prepare for the next sales operation.

In addition, when the sales conditions are not met and the sales start signal S _e is not applied from terminal T ₄ , when the payment button is pressed, a refund will be given if no sales have been made, and change will be paid if sales have been made. will be carried out.

The signal from terminal T ₄ and the output of flip-flop 56 for holding the sales start signal are applied to NOR circuit 84 . The NOR circuit 84 outputs a signal "1" when the signal from the terminal _T4 is "0" and the flip-flop 56 for holding the sales start signal is not set, and adds this signal to the AND circuit 85.

The other input terminals of the AND circuit 85 are connected to the output of the delay flip-flop 58, the output of the timer 54, and a signal obtained by inverting the output of the product delivery signal holding flip-flop 68.

By the way, when the settlement button is pressed and the settlement signal holding flip-flop 74 is set, this set output is applied to the delay flip-flop 58 via the OR circuit 57, setting this flip-flop 58, and then setting the set output. is added to the timer 54 via the OR circuit 53 and the timer 54
make it work.

Therefore, the payment button is pressed, the operation of the timer 54 is terminated, and the flip-flop 6 for the product sending signal is activated.
8 is not set, the AND condition of the AND circuit 85 is satisfied, and a signal "1" is applied to the AND circuits 79 and 80 via the OR circuit 78. As mentioned above, the AND circuits 80 and 79 are supplied with the output of the sales memory flip-flop 70 and a signal obtained by inverting this.If the flip-flop 70 is not set, the AND circuit 79
If the AND condition is satisfied and the signal “1” is applied to the refund command circuit 81, and the flip-flop 70 is set, the AND condition of the AND circuit 80 is satisfied and the signal “1” is sent to the change command circuit 81 via the OR circuit 740. Add to circuit 75.

By the way, when a coin is inserted into the vending machine during the vending operation, the coin counters 29 and 3
The count values of 0 and 31 fluctuate, which is not desirable. Therefore, the sales start signal S _e applied to the terminal _T4 , the output of the flip-flop 56 for holding the sales start signal, the output of the flip-flop 74 for holding the payment signal, and the output of the flip-flop 68 for holding the product delivery signal are connected to the OR circuit 86 and the output of the flip-flop 68 for holding the product delivery signal. 87. In addition to the coin acceptance rejection device 42 via the OR circuit 41, if at least one of the above signals is "1", the coin acceptance rejection device 42 is operated to prevent coin insertion.

In addition, a collection command circuit 71, a change command circuit 75,
Since the refund command circuit 81 is configured to hold the signal "1" during the operation of collecting money, dispensing change, and refunding, the signals from the collection command circuit 71, change command circuit 75, and refund command circuit 81 are Signal OR circuit 8
8. In addition to the coin acceptance refusal device 42 via the OR circuit 40 and the OR circuit 41, the coin acceptance refusal device 42 is operated to prevent the insertion of coins during the operation of collecting money, dispensing change, or refunding money. configured to do so.

Next, the collection operation, refund operation, and change dispensing operation will be explained in detail.

Collection operation The collection operation is based on the count value of the 10 yen coin counter 29.
This is done by subtracting the sales price R _SP from R _A. Here, if the sales set price R _SP cannot be subtracted from the count value R _A of the 10 yen coin counter 29, a transfer is made from the 50 yen coin counter 30 or the 100 yen coin counter 31 to the 10 yen coin counter 29. It will be done.

When the signal “1” is held in the collection command circuit 71, this signal is sent to the comparator circuit 8 via the line 880.
Add to 9.

The comparison circuit 89 receives the sales set price _RSP from the serialization register 46 and the 10 yen coin counter 2.
9 count amount R _A is added, and the set price
A comparison is made between R _SP and the counted amount R _A of the 10 yen coin counter 29.

In this comparison, if the count value R _A of the 10 yen coin counter 29 is greater than or equal to the set price R _SP (R _A ≧ R _SP ), then the 10 yen coin counter 2
Since the set price R _SP can be subtracted from the count value R _A of 9, the count value of the 10 yen coin counter 29
The set price R _SP is subtracted from R _A. This subtraction is performed as follows.

When R _A ≧ R _SP holds true, the comparator circuit 89
Sends a signal “1” to 0.

The signal on line 90 is applied to gate circuit 91 as a gate signal. On the other hand, a pulse signal indicating the sales set price R _SP from the serialization register 46 is applied to the gate circuit 91 .

Therefore, when the signal "1" is sent to the line 90, the gate circuit 91 is opened and a pulse signal indicating the sales set price R _SP is sent via the line 92 to the subtraction command terminal of the 10 yen coin counter 29, and the 10 yen coin is sent to the subtraction command terminal of the 10 yen coin counter 29. At the same time, this pulse signal is applied to the count input terminal of the 10 yen coin counter 29 via the OR circuit 93 and the OR circuit 26.

In this way, the sales set price R _SP is subtracted from the count value R _A of the 10 yen coin counter 29.

However, in the comparison by the comparison circuit 90, the count value R _A of the 10 yen coin counter 29 is the sales set price.
When it is smaller than R _SP ( _RA < R _SP ), the sales set price R _SP cannot be subtracted from the count value R _A of the 10 yen coin counter 29. At this time, a part of the counted amounts R _B and R _C of the 50 yen coin counter 30 or the 100 yen coin counter 31 is transferred to the 10 yen coin counter R _A.
, so that R _A ≧ R _SP is established, and then the sales set price R _SP is subtracted from the count value R _A of the 10 yen coin counter 29. This transfer operation is performed as follows.

When the comparison circuit 89 compares, a signal "1" is sent to the line 94 if R _A <R _SP .

The signal "1" on line 94 is applied to AND circuit 95. The other input terminals of the AND circuit 95 include
Comparison circuit 9 whose output is "1" when the count value R _B of the 50 yen coin counter 30 is 0 (R _B = 0)
The signal from 6 is inverted and added.

Therefore, the AND circuit 95 is opened when the count value R _B of the 50 yen coin counter 30 is not 0, and applies a signal "1" to the 50 yen → 10 yen transfer command circuit 97.

The 50 yen → 10 yen transfer command circuit 97 subtracts 50 yen from the counted value R _B of the 50 yen coin counter 30 and instructs the transfer calculation to add the counted value R _A =50 to the 10 yen coin counter 29. . That is, when a signal "1" is applied from the AND circuit 95, one pulse is sent to the line 98, and this pulse signal is applied to the subtraction command terminal of the 50 yen coin counter 30, and the signal is sent via the OR circuit 99 and the OR circuit 27. In addition to the count input terminal of the 50 yen coin counter 30, the count value
Subtract 50 from R _B , simultaneously send 5 pulses to line 100, add this pulse signal to the addition command terminal of 10 yen coin counter 29, and send 10 yen coins via OR circuit 93 and OR circuit 26. In addition to the count input terminal of the counter 29, the count value
Add 50 to R _A.

When the transfer from the 50 yen coin counter 30 to the 10 yen coin counter 29 by the 50 yen → 10 yen transfer command circuit 97 is completed, the line 101 and the OR circuit 10
A signal "1" is applied to the comparator circuit 89 via 2, and the count value R _A of the 10 yen coin counter 29 is again
A comparison is made between the sales price RSP and the sales set price _RSP .

In this way, the transfer from the 50 yen coin counter 30 to the 10 yen coin counter 29 continues until the counted value R _A of the 10 yen coin counter 29 becomes R _A ≧ R _SP with respect to the sales set price R _SP . I could go on, but
When the count value R _B of the 50 yen coin counter 30 becomes 0, the output of the comparator circuit 96 becomes "1", the AND condition of the AND circuit 95 no longer holds true, and the 50 yen → 10 yen transfer command circuit 97 ceases to operate. At this time, the money is transferred to the 100 yen coin counter 31.

A signal from the comparison circuit 96 which outputs "1" when the count value of the 50 yen coin counter 30 is 0 is applied to the AND circuit 103.

The other input terminals of the AND circuit 103 are a signal on line 94 indicating that the counted value R _A of the 10 yen coin counter 29 is smaller than the set price R _SP and a signal on the line 94 indicating that the counted value R _C of the 100 yen coin counter 31 is 0. “1” at some point
A signal obtained by inverting the output signal of the comparator circuit 104 that outputs is added.

Therefore, the AND condition of the AND circuit 103 is satisfied when the signal on the line 94 is "1", R _B = 0, and R _C ≠ 0, and the signal "1" is applied to the 100 yen → 50 yen transfer command circuit 105. At the same time, in addition to the 100 yen coin acceptance solenoid control section 106, the held 100 yen coin is accepted. This 100 yen coin acceptance solenoid control section 106 includes a flip-flop 1063 that sets and inputs the output of the AND circuit 103 via an AND circuit 1061 and an OR circuit 1062;
A timer T106 that operates when the flip-flop 1063 is set; a flip-flop 1068 that uses the output of the timer T106 as a set input via AND circuits 1064 and 1065; and a reset circuit for the flip-flop 1063 that uses the outputs of the AND circuits 1065 and 1067 as input. OR circuit 1
069, the set output of the flip-flop 1068 operates the 100 yen coin acceptance solenoid (escrow cash box solenoid) CB to control the acceptance of the held inserted 100 yen coin.

The output of the flip-flop 1068 is added as another input to the AND circuit 1067, and the inverted output is added as another input to the AND circuits 1065 and 1061.
AND circuit 1061 that uses the output of 66 as another input
added to 0. Also flipflop 10
The output of 63 is inverted and added to an AND circuit 1064 as another input of the AND circuit 1066.

Therefore, the signal “1” from the AND circuit 103
is the other input "1" of the AND circuit 1061, so it is applied to the flip-flop 1063 via the AND circuit 1061 and the OR circuit 1062, setting the flip-flop 1063, and the set output activates the timer T106.
After a delay time of 106, the AND circuit 1064 is opened, and its output "1" sets the flip-flop 1068 via the AND circuit 1065, and the 100 yen coin acceptance solenoid CB is energized, and the 100 yen coin 1 is energized.
accept the sheet. Further, the output of the AND circuit 1065 resets the flip-flop 1063 via the OR circuit 1068, but this time the AND circuit 1066 is opened and its output "1" is applied to the AND circuit 10610.
Since the flip-flop 1068 output "1" is added to the other input of 0, it is opened and its output "1"
is the flip-flop 1 through the OR circuit 1062.
Set 063 again.

The output of this flip-flop 1063 opens the AND circuit 1064 after the timer delay time as described above, but this time, since the flip-flop 1068 is set, the AND circuit 1067 is opened, and its output "1" is applied to the flip-flop 1068.
is reset, the 100 yen coin acceptance solenoid CB is demagnetized, and one acceptance operation is completed. That is,
It is energized for a sufficient time to accept 100 yen coins, and when continuously accepting 100 yen coins, it waits for sufficient time for the second and subsequent coins in the escrow to fall into the 100 yen coin acceptance solenoid CB.

The 100 yen → 50 yen transfer command circuit 105 transfers 100 from the count value R _C of the 100 yen coin counter 31 to the count value R _B of the 50 yen coin counter 30, and one pulse is sent to the line 107. is sent out, this pulse signal is added to the 100 yen coin counter 31 via the OR circuit 28, 100 is subtracted from the count value R _C , and two pulses are sent out to the line 108 at the same time.
This pulse signal is applied to the 50 yen coin counter 30 via the OR circuit 99 and the OR circuit 27, and the counted value is
Add 100 to R _B.

When the transfer of 100 yen from the 100 yen coin counter 31 to the 50 yen coin counter 30 by the 100 yen → 50 yen transfer command circuit 105 is completed, a signal "1" is output to the line 109, and this signal is passed to the AND circuit 110.
Add to.

Since a signal that becomes "1" when one 100 yen coin is accepted from the escro solenoid 106 is applied to the other input terminal of the AND circuit 110,
When acceptance of 100 yen coin is confirmed, AND circuit 1
10 is opened and a signal "1" is applied to the comparison circuit 89 via the OR circuit 102, and the count value R _A of the 10 yen coin counter 29 and the set price R _SP are again compared. By the way, this time, the count value R _B of the 50 yen coin counter 30 is not 0, so the AND condition of the AND circuit 95 is satisfied, and the 50 yen → 10 yen transfer command circuit 97
Accordingly, a transfer is made from the 50 yen coin counter 30 to the 10 yen coin counter 29.

In this way, from the 100 yen coin counter 31
When transferring to the 50 yen coin counter 30 or transferring from the 50 yen coin counter 30 to the 10 yen coin counter 29, the counted value R _A of the 10 yen coin counter 29 is R _A with respect to the sales set price R _SP . It can be repeated until ≧R _SP .

When R _A ≧ R _SP holds true in the comparator circuit 89,
A signal "1" is sent to the line 90, and the sales set price R _SP is subtracted from the count value R _A of the 10 yen coin counter 29 as described above.

Further, the signal "1" on the line 90 is applied to the serialization register 46 and the collection command circuit 71, resetting them and ending the collection operation.

When the money collection operation is completed in this manner, one sales operation is completed, and the next sale or payment is ready.

By the way, as long as the settlement button is not pressed, if the sales conditions are met, the sales and collection operations described above can be repeated to make continuous sales any number of times.

Furthermore, when each sale operation is completed, the output of the OR circuit 86 becomes "0", the output of the OR circuit 41 becomes "0", and the operation of the coin acceptance refusal device 42 is stopped, so that the operation of the coin acceptance refusal device 42 is stopped. Coins can be inserted every time the operation is completed.

Next, referring to FIG. 4, the refund operation when the signal "1" is stored in the refund command circuit 81 and the change payout operation when the signal "1" is stored in the change command circuit 75 will be explained.

Refund operation If you insert coins but press the checkout button without purchasing anything, the refund command circuit 8 will be activated as described above.
A signal “1” is stored in “1”.

The signal “1” from the refund command circuit 81 is line 1.
11 (FIG. 3) is applied to an escrow flip-flop 113 via an OR circuit 112 to set it.

When the escrow flip-flop 113 is set, this set output "1" is applied to the escrow solenoid 114, and the escrow solenoid 11
Activate 4 and return all the 100 yen coins that were on hold.

Further, the signal "1" from the refund command circuit 81 (FIG. 3) is applied to the 10 yen coin counter 29, the 50 yen coin counter 30, and the 10 yen coin counter 31 via the OR circuit 115. counter 2
9, 30, and 31 are placed in a subtraction mode, and this signal "1" is applied to flip-flop 118 via line 116 and OR circuit 117 to set it.

The set output "1" of flip-flop 118 is applied to timer 119.

The timer 119 is connected to the timers 54 and 63 (third
It has the same configuration as (Fig.) and has a delay time t ₃ ,
When the signal "1" is applied, the output is configured to rise to "1" after time _t3 has elapsed.

Therefore, the output of flip-flop 118, the signal obtained by inverting the output of timer 119, and the NOR circuit 1
20 (the output of the NOR circuit 120 is "0" only when the timer 121, which will be described later, is operating; at this time, the timer 121 is not operating, so the output of the NOR circuit 120 is "1"). The AND condition of the AND circuit 122 that is applied is the timer 119
is established during the operation of the AND circuit 12, and the signal “1” is
Add to 3.

Since the output of the escrow flip-flop 113 is applied to the other input terminal of the AND circuit 123, the AND condition of the AND circuit 123 is satisfied, and a signal "1" is applied to the 100 yen coin counter subtraction command circuit 124.

The 100 yen coin counter subtraction command circuit 124 is
A number of pulses equal to the number of 100 yen coins returned by the energization of the escro solenoid 114,
via line 125, OR circuit 28 (Fig. 3)
Add to the count input terminal of the 100 yen coin counter 31.

At this time, the 100 yen coin counter 31 is cleared by a signal on line 125, which will be described later, and the count value R _C of the 100 yen coin counter 31 becomes 0.

Note that the operating time t ₃ of the timer 119 ensures the operating time for the escrow solenoid 114 to return the 100 yen coin.

When the operating time _t3 of timer 119 ends, the output of flip-flop 118, the output of timer 119,
The AND condition of the AND circuit 126 to which the output of the NOR circuit 120 is added is satisfied, and a signal "1" is applied to the AND circuit 127.

Since the set output "1" of the escrow flip-flop 113 is added to the other input terminal of the AND circuit 127, the AND condition of the AND circuit 127 is also satisfied, and the signal "1" is applied to the line 12.
8. Flip-flop 1 via OR circuit 129
30, and at the same time, the signal "1" on the line 128 is applied to the reset terminal of the flip-flop 118 via the OR circuit 131 to reset it, and at the same time, the signal "1" on the line 128 is applied to the flip-flop 113 for escrow. In addition to the reset terminal, this is also reset.

The set output "1" of flip-flop 130 is applied to timer 121. The timer 121 is similar to the timer 119, and has an operating time of time _t2 , and when a signal "1" is applied, the output is
After _t2 elapses, it rises to “1”.

Therefore, the output of the NOR circuit 120 to which the output of the flip-flop 130 and the output of the timer 121 are added is "0" while the timer 121 is operating.

When the operating time _t2 of the timer 121 ends, the output of the timer 121 rises to "1", and the AND condition of the AND circuit 132 to which the output of the flip-flop 130 and the output of the timer 121 are added is satisfied, and the signal "1" ” is applied to the reset terminal of flip-flop 130 to reset it.

When the flip-flop 130 is reset, the output of the timer 121 also becomes "0", and the output of the NOR circuit 120 becomes "1".

Here, the AND condition of the AND circuit 133 to which the output of the NOR circuit 120 and the signal obtained by inverting the output of the flip-flop 118 are applied is satisfied, and a signal "1" is applied to the AND circuit 134.

The output of the escro flip-flop 113 is inverted and applied to the other input terminal of the AND circuit 134. At this time, since the escrow flip-flop 113 has been reset, the AND condition of the AND circuit 134 is satisfied, and the signal becomes "1".

Here, the counter 1410 is used to issue a command when a coin is not dispensed due to the coin dispensing actuator, and this will be described later.

The set output "1" of the flip-flop 138 is applied to the coin dispensing motor _M01 through an AND circuit 1380 whose other input is a signal obtained by inverting the output of the flip-flop 217 for rotating the motor _M02 , which will be described later. Motor M ₀₁ is rotated on the condition that ₀₂ is not rotating.

The coin dispensing motor _M01 rotates a coin dispensing actuator (not shown), and rotates the 10 yen coin tube (A tube) or the 50 yen coin tube (B tube) shown in FIG.
Coins are dispensed from the auxiliary tube (C tube) for 10 yen coins or 50 yen coins, and if the A tube switching solenoid 141 and the B tube switching solenoid 142, which will be described later, are not energized, the coin is 50 yen. It is dispensed from the coin tube (B tube).

Carrier switch 143 for coin dispensing actuator M ₀₁ interlocked with the coin dispensing motor M ₀₁
(Fig. 4) is arranged, and when the coin dispensing actuator is rotated by the rotation of the coin dispensing motor _M01 , the carrier switch 143 is turned on, the coin dispensing actuator rotates once, and coin dispensing is completed. and turns off.

The fall of the carrier switch 143 for motor _M01 is detected by the fall detection circuit 144, and the signal "1" is sent to the AND circuit 1 through the OR circuit 145.

Therefore, if the carrier switch 143 for motor _M01 falls during the operation of the timer 119, the AND condition is satisfied and the AND circuit 146 sends the signal "1" to the reset terminal of the flip-flop 138 via the OR circuit 149. In addition, the flip-flop 138 is reset and the coin dispensing motor _M01 is stopped.

Further, the coin dispensing port (Fig. 1) is provided with a dispensing coin detection switch 150 for detecting the dispensing of coins, and the coin dispensed by the operation of the coin dispensing motor _M01 passes through the coin dispensing port. When this is confirmed, a signal “1” is applied to the AND circuit 151.

The other input terminal of the AND circuit 151 is a timer 1.
19 is operating and escrow flip-flop 11
The output of the AND circuit 148 indicating that 3 has been reset is added.

Therefore, the AND condition of the AND circuit 151 is satisfied, and the signal "1" is applied to the flip-flop 152 for holding the coin payout confirmation signal and set.

Flip-flop 15 for holding coin payout confirmation signal
When 2 is set, the set output "1" is applied to the AND circuit 201 via the OR circuit 200.

The other input terminal of the AND circuit 201 is a timer 1.
AND circuit 16 which becomes “1” at the end of operation 19
When the operation of the timer 119 ends, the AND condition is satisfied, and the AND circuit 201 applies a signal "1" to the reset terminal of the clock signal holding flip-flop 165 to reset it.

Further, the signal “1” via the OR circuit 200 is applied to the AND circuit 203 via the OR circuit 202.

Since the output of the AND circuit 161 is applied to the other input terminal of the AND circuit 203 in the same way as described above, the AND condition is satisfied when the operation of the timer 119 ends, and the signal "1" is sent to the counter 1410 via the OR circuit 204. In addition, counter 1410 is reset.

Furthermore, the rising edge of the set output of the flip-flop 152 for holding the coin dispensing confirmation signal is detected by the rising edge detector 1.

The other input terminal of the AND circuit 154 is a timer 1.
The output of an AND circuit 148 whose output is "1" when the circuit 19 is in operation is added.

Therefore, the AND condition of the AND circuit 154 is satisfied, and a signal "1" is applied to the AND circuit 155.

The AND circuit 155 is supplied with an inverted output of the comparison circuit 136 which outputs a signal "1" when the count value R _B of the 50 yen coin counter 30 becomes 0, and in this case, it is a refund operation. Therefore, when a 50 yen coin is inserted, R _B ≠ 0, and the AND condition of the AND circuit 155 is satisfied, and the signal “1” is output.
It is added to the 50 yen coin counter subtraction command circuit 156.

The 50 yen coin counter subtraction command circuit 156 is configured to apply one pulse to the 50 yen coin counter 30 when the signal "1" is applied, and it subtracts 50 from the count value R _B of the 50 yen coin counter 30. (the subtraction path is not shown).

Further, the output “1” of the AND circuit 155 is applied to the AND circuit 157.

An inverted output from a comparator circuit 158, which outputs "1" when the counted value _RBN of the 50 yen coin storage amount counter 33 reaches 0, is applied to the other input terminal of the AND circuit 155.

Therefore, the AND condition of the AND circuit 157 is naturally satisfied, and a signal "1" is applied to the 50 yen coin storage amount counter subtraction command circuit 159.

50 yen coin storage amount counter subtraction command circuit 159
has the same configuration as the command circuit 156,
When the signal "1" is applied, one pulse is added to the 50 yen coin storage counter 33, and 1 is subtracted from the count value _RBN (the subtraction path is not shown).

In this way, one 50 yen coin is paid out, and 50
50 is subtracted from the count value R _B of the yen coin counter 30, and 1 is subtracted from the 50 yen coin storage counter 33, but the operating time of the timer 119 is
Since t ₃ is set longer than the time required for the above operation, if the above operation is performed normally, this operation ends within the operating time t ₃ of the timer 119.

When the operating time _t3 of timer 119 ends, NOR circuit 120, flip-flop 118 and timer 1
The AND condition of the AND circuit 160 to which the output of 19 is added is satisfied, and the signal "1" is applied to the AND circuit 161.
Add to.

A signal obtained by inverting the output of the flip-flop 113 for escrow is applied to the other input terminal of the AND circuit 161, and the AND condition of the AND circuit 161 is satisfied, and the signal "1" is transferred to the flip-flop 152 for holding the coin payout confirmation signal. In addition to the reset terminal of
It is added to the reset terminal of flip-flop 130 via OR circuit 129 and set.

The setting of flip-flop 130 restarts the operation of timer 121.

When the operating time _t2 of this timer 121 ends,
The AND condition of the AND circuit 133 is satisfied again, and the flip-flop 138 is set via the AND circuits 134, 135 and the OR circuit 137, and one 50 yen coin is dispensed by the same operation as above.

This 50 yen coin dispensing operation continues until the count value R _B of the 50 yen coin counter 30 becomes 0.

By the way, if the carrier switch 143 for the motor _M01 does not fall even though the coin dispensing motor _M01 rotates when R _B ≠ 0, in this case it means that a coin has become stuck in the coin dispensing actuator. means. In this case, processing is performed as follows.

The output of the carrier switch 143 for motor M ₀₁ and the output of the AND circuit 162 added to the output of the flip-flop 138 are applied to an AND circuit 164 via an OR circuit 163.

The output of the AND circuit 134 is applied to the other input terminal of the AND circuit 164.

Therefore, the coin dispensing motor _M01 rotates and the carrier switch 143 for the motor _M01 is turned on, but it does not turn off during the operation time _t3 of the timer 119 and continues to operate during the operation time of the timer 121. At the end of _t2 , the AND condition of the AND circuit 134 is satisfied again, and when the flip-flop ₁₃₈ is set, the AND condition of the AND circuit 164 is satisfied and the signal "1" to the flip-flop 165 for holding the lock signal and set it.
This signal "1" is applied to flip-flop 166 to set it.

The set output "1" of flip-flop 166 is applied to reverse rotation command circuit 167.

The reverse command circuit 167 is a coin dispensing motor
This command commands the reverse rotation of M ₀₁ and M ₀₂ , and here, the reverse rotation of the coin dispensing motor M ₀₁ is commanded, and the motor M ₀₁ rotates in the reverse direction.

At this time, the output of the flip-flop 138 is passed through the OR circuit 139 to the AND circuit 13.
Since the output of 4 is added to the AND circuit 140, the AND condition of the AND circuit 140 is satisfied, and the signal "1" is added to the counter 1410.
As well as incrementing the count by 1, this signal becomes “1”
is applied to the flip-flop 1 via the OR circuit 117.
In addition to step 18, the timer 119 is started.

When the operating time _t3 of the timer 119 ends, the AND condition of the AND circuit 161 is satisfied, and the flip-flop 138 is reset via the AND circuit 161 and the OR circuit 149.
When the operation of 21 is started and completed and the flip-flop 138 is set via AND circuits 139, 134, 135 and OR circuit 137,
The coin dispensing motor _M01 rotates in the normal direction.

As a result, when a coin is dispensed and the dispensed coin detection switch 150 confirms that the coin is dispensed, a signal “1” indicating confirmation of the coin dispense is output.
is applied to the flip-flop 152 for holding the coin payout confirmation signal via the AND circuit 151 and set, so this set output "1" is applied to the counter via the OR circuits 200, 202, the AND circuit 203, and the OR circuit 204. 1410 to reset the counter 1410, and at the same time, this set output "1" is applied via the OR circuit 200 and the AND circuit 201 to the reset terminal of the lock signal holding flip-flop 165 to reset it.

As a result, normal dispensing of 50 yen coins is performed in the same manner as described above.

However, if the coins are not dispensed even when the coin dispensing motor _M01 is rotated in the forward and reverse directions, and the flip-flop 152 for holding the coin dispensing confirmation signal is not set, the operation of the timer 119 during the final forward rotation operation is terminated. Subsequently, the timer 121 operates, and when it ends, the count value of the counter 1410 becomes three.

Here, since the counter 1410 is configured to output a signal "1" when the count value reaches 3, this signal "1" is applied to the AND circuit 169 via the OR circuit 168.

On the other hand, the output of the AND circuit 170, in which the output of the OR circuit 120, the output of the flip-flop 118, and the output of the timer 119 are added, and an AND condition is satisfied when the operation of the timer 119 ends, is a signal obtained by inverting the output of the flip-flop 113 for escrow. A signal obtained by inverting the output of the flip-flop 152 for holding the coin payout confirmation signal is applied to an AND circuit 171.

The AND circuit 171 applies a signal "1" to the AND circuit 172 if the sending of coins is not confirmed at the end of the operation of the timer 119, and the AND condition is satisfied.

The other input terminal of the AND circuit 172 has R _B =
Since the signal of the comparison circuit 136 which outputs the signal "1" when the signal is 0 is reversed and added, R _B ≠0
If so, the AND condition of the AND circuit 172 is satisfied, and this signal "1" is applied to the AND circuit 169.

Therefore, the AND circuit 169
If 3 is counted to 0 and the 50 yen coin is not dispensed during the operation time of the timer 119, this is true, and the signal "1" is applied to the flip-flop 173 to set it, and the signal "1" is applied to the OR circuit 1.

The 50 yen → 10 yen transfer command circuit 175 is connected to line 17.
6. Add a number of pulse signals corresponding to the count value R _B of the 50 yen coin counter 30 via the OR circuit 27 (Fig. 3), set R _B to 0, and then via the line 177 and the OR circuit 26, A number of pulse signals corresponding to the counted value R _B of the coin counter 30 are applied to the 10 yen coin counter 29, and the counted value R _A of the 10 yen coin counter 29 is set to R _A + _RB .

In this way, the count value R _B of the 50 yen coin counter 30 is transferred to the count value R _A of the 10 yen coin counter 29, making R _B = 0, but at the same time,
The output “1” of the counter 1410 is the OR circuit 20
0 is applied to the reset terminal of the flip-flop 165 for holding the lock signal via the AND circuit 201, and when this is reset, the output of the OR circuit 200 is applied via the OR circuit 202, the AND circuit 203, and the OR circuit 204 to reset the counter 1410. In addition to the terminal, reset this.

5, R _B is transferred to R _A , and when R _B = 0, the output of the AND circuit 134, the output of the comparator circuit 136, and the output of the comparator circuit 178, which outputs "1" when R _A = 0, are inverted. The AND condition of the AND circuit 179 is satisfied, and then the 10
Payout of yen coins begins.

The output “1” of the AND circuit 179 is the AND circuit 1
Added to 80.

A signal obtained by inverting the outputs of the AND circuit 181 and the AND circuit 182 is applied to the other input terminal of the AND circuit 180.

The AND circuits 181 and 182 will be explained later in the operation of dispensing change, but here their respective outputs are "0".

Therefore, the AND condition of AND circuit 180 is satisfied, and a signal "1" is applied to flip-flop 184 to set it.

The set output "1" of the flip-flop 184 is applied to the A-tube switching solenoid 141 to energize the solenoid 141 via an AND circuit 1840 whose other input is an inverted signal of the output of a flip-flop 199, which will be described later.

The A tube switching solenoid 141 switches between the main tube for 50 yen coins (B tube) and the main tube for 10 yen coins (A tube), and when energized, the coin dispensing motor M ₀₁
The coin dispensing tube is switched from the main tube for 50 yen coins (B tube) to the main tube for 10 yen coins (A tube).

Further, the output signal “1” of the AND circuit 179 is applied to the AND circuit 185.

Since the output of the AND circuit 181 (here "0") is inverted and applied to the other input terminal of the AND circuit 185, the AND condition of the AND circuit 185 is satisfied, and the signal "1" is sent to the OR circuit 137. via the flip-flop 138 and set it.

When the flip-flop 138 is set, the set output "1" rotates the coin dispensing motor _M01 , and a 10 yen coin is dispensed from the main tube for 10 yen coins.

The 10 yen coin is dispensed in the same manner as the 50 yen coin.

That is, when the carrier switch 143 for the coin dispensing motor _M01 is turned off and this fall is detected by the fall detection circuit 144, this signal "1" is sent to the flip-flop 138 via the OR circuit 145 and the AND circuit 146. In addition to the reset terminal of
M ₀₁ is stopped and one 10 yen coin is dispensed.

Further, the coin payout confirmation signal from the payout coin detection switch 150 is applied to a coin payout confirmation signal holding flip-flop 152 via an AND circuit 151, and this is set.
A rising edge detection circuit 153 detects the rising edge of the second set output.
This detection signal "1" is applied to the AND circuit 186 via the AND circuit 154.

Therefore, the AND condition of the AND circuit 89 is satisfied and the signal “1” is set to 10.
In addition to the yen coin storage amount counter subtraction command circuit 191, 1 is subtracted from the counted value R _AN of the 10 yen coin storage amount counter 32.

This completes the operation of dispensing one 10 yen coin. In this 10 yen coin dispensing operation, the count value R _A of the 10 yen coin counter 29 becomes 0, and the comparator circuit 1
This continues until the output of 62 becomes "1".

In this way, 100 yen, 50 yen, 10
The same number of 100 yen, 50 yen, and 10 yen coins as the yen coins are returned and the return operation is completed, but while the 10 yen coin is being dispensed, the 10 yen coin gets stuck in the coin dispensing actuator and the carrier switch 143 is turned down. When the rotation stopped, the reverse command circuit 167 was operated in the same manner as described above to reverse the coin dispensing motor _M01 , and even after three operations of forward rotation, reverse rotation, and forward rotation, the dispensation of 10 yen coins was not confirmed. In this case, a signal "1" indicating a failure is applied to the stop device 194 as follows. That is, the count value of the counter 1410 becomes 3 and an output "1" is added to the AND circuit 192.

The other input terminal of the AND circuit 192 is a timer 1.

The AND condition of the AND circuit 192 is satisfied when the timer 119 ends, and the signal "1" is stopped via the OR circuit 193. Add to device 194.

The stop device 194 performs appropriate processing, such as stopping the vending operation of the vending machine, since it means that a failure has occurred when the signal "1" is applied.

In the return operation described above, only the main tube for 10 yen coins (A tube) and the main tube for 50 yen coins (B tube) are involved, and the auxiliary tubes (C tube, D tube) are not involved.

Here, a case where the C tube is used as an auxiliary tube for 50 yen coins will be explained.

If the C tube is an auxiliary tube for 50 yen coins, the C tube switching signal DBT applied from the terminal T ₉ (FIG. 4) is "1".

50 yen coins are dispensed from the main tube (B tube)
When the coins are paid out with priority and the counted value _RBN of the 50 yen coin storage counter 33 is not 0, the refund operation is performed as follows, similar to the above-mentioned refund operation.

In addition to the set terminal of , the flip-flop 118 is set and the operation of the timer 119 is started.

A 50 yen coin is dispensed by the rotation of the coin dispensing motor M ₀₁ , and the carrier switch 14 for the motor M ₀₁ is activated.
3 is turned on and off, and the fall of the carrier switch 143 is detected by the fall detection circuit 144.
This detection signal "1" is passed through an OR circuit 145, an AND circuit 146, and an OR circuit 149 to reset the flip-flop 138 to stop the coin dispensing motor.

Further, when the payout of a coin is confirmed by the payout coin detection switch 150, a signal "1" is applied to the flip-flop 152 via the AND circuit 151, and the flip-flop 152 is set.

Make _A + R _B.

Next, count value R _BN of 50 yen coin storage counter 33
Suppose that is 0. Note that R _BN = 0 here means 50
does not mean that the main tube (B tube) of coins is completely empty. A state of R _BN =0 indicates a state where at least an amount equivalent to the maximum change of 50 yen, for example, one or more coins, remains in the B tube.

By the way, the signal "1" stored in the change payout command circuit 75 (FIG. 3) is applied to the flip-flop 197 via the line 196, and the flip-flop 197 is set.

The set signal "1" of flip-flop 197 is applied to AND circuit 198.

When the operation of the timer 121 ends, the AND circuit 13
When the AND condition of 3 is established, a signal "1" is applied to the flip-flop 138 via the AND circuits 134, 135 and the OR circuit 137, and when the coin dispensing motor _M01 is rotated by the setting of the flip-flop 138, a 50 yen coin is released from the C tube. will be paid out.

This payout operation is performed in the same manner as above,
50 yen coin counter 3 for every 50 yen coin dispensed
50 is subtracted from the count value R _B of 0, and 1 is subtracted from the 50 yen coin storage amount counter 33.

In this way, the operation of dispensing 50 yen coins from the C tube continues until R _B becomes 0, but even though R _B ≠ 0, even if the coin dispensing motor M ₀₁ is rotated, the 50 yen coin does not come out from the C tube. Assume that it is not paid out.

At this time, if the payout coin is not bitten, an AND circuit is added to which the output of the flip-flop 197, the output of the comparator circuit 158 indicating R _BN =0, and the inverted signal of the output of the flip-flop 165 for holding the lock signal are added. The AND condition 205 is satisfied, and a signal "1" is applied to the AND circuit 169 via the OR circuit 168.

The output of the AND circuit 172 is applied to the other input terminal of the AND circuit 169, which indicates that no coin was paid out even though R _B ≠0 at the end of the timer 119.

Therefore, when the operation of the timer 119 ends, the AND condition of the AND circuit 169 is satisfied, and the signal "1" is applied to the flip-flop 173 to set it, and this signal "1" is passed through the OR circuit 174 to 50 yen→ In addition to the 10 yen transfer command circuit 175, the count value R _B of the 50 yen coin counter 30 is set to 0, and this is transferred to the count value R _A of the 10 yen coin counter 29.

Further, the output "1" of the AND circuit 169 is applied to the reset terminal of the counter 1410 via the OR circuit 204 to clear the contents of the counter 1410, and at the same time, this signal "1" is applied to the reset terminal of the flip-flop 197 via the OR circuit 206. added to the terminal and resets it.

By the way, at this time, flip-flop 197
A flip-flop 165 for holding a lock signal is set to output the output from the comparator circuit 158 indicating that R _BN =0, and the output from the terminal T ₉ indicating that the C tube is for 50 yen coins, via the OR circuit 208. The AND condition of the AND circuit 207 is satisfied, and a signal “1” is applied to the AND circuit 209.

The output of the C tube blank signal holding flip-flop 19 is inverted and applied to the other input terminal of the AND circuit 209.

Here, since the flip-flop 19 is not set, the AND condition of the AND circuit 209 is satisfied, and the signal "1" is passed through the OR circuit 210 to the flip-flop 19 for holding the C tube blank signal.
In addition to this, set this.

Flip-flop 1 for holding C tube blank signal
If a 50 yen coin is dispensed with 9 set, then the AND circuit 198
Since the AND condition is not satisfied and the C tube switching solenoid 142 is not energized, the coin dispensing motor M ₀₁ is set by the flip-flop 138.
When it rotates, a 50 yen coin will be dispensed from the B tube.

When dispensing 50 yen coins from B-tube,
Flip-flop 1 for holding lock signal when R _B ≠ 0
65 is not set, and flip-flop 152 for holding the coin dispensing confirmation signal is not set when the timer 119 ends, the AND condition of AND circuit 169 is satisfied, and flip-flop 173 is set in the same manner as described above. Activate the yen → 100 yen transfer command circuit 175 to transfer R _B to R _A.

At this time, the AND condition of the AND circuit 207 is satisfied, but since the flip-flop 19 for holding the C tube blank signal is set, the output of the AND circuit 207 and the output of the flip-flop 19 are added to the AND circuit 211. The AND condition is satisfied, and a signal "1" is applied to the blank signal holding flip-flop 19 via the OR circuit 212 to reset it.

By the way, at the start of dispensing 50 yen coins,
R _B ≠ 0, R _BN = 0, and flip-flop 173
is set, the output of the AND circuit 213 to which the output of the AND circuit 123, the inverted signal of the output of the comparison circuit 136 (R _B =0), and the output of the comparison circuit 158 (R _BN =0) are added. The AND condition is satisfied.

At this time, the output "1" of the AND circuit 213 is applied to the reset terminal of the flip-flop 173 via the OR circuit 300 to reset it, and at the same time, the output "1" is applied via the OR circuit 174 to the reset terminal of the flip-flop 173.
In addition to the 10 yen transfer command circuit 175, R _B is transferred to R _A and R _B is set to 0.

Thus, the count value of the 50 yen coin counter 30
R _B becomes 0, the dispensing of 50 yen coins is completed, and then
10 yen coins are dispensed.

When dispensing a 10 yen coin, R _B =0, and assuming that R _A ≠0, the output of the AND circuit 134, the output of the comparator circuit 136 (R _B =0), and the comparator circuit 178
The process starts when the AND circuit 179 to which the inverted signal (R _A ≠ 0) is applied is established.

The output “1” of the AND circuit 179 is the AND circuit 1
80 to the flip-flop 184, sets it, energizes the A tube switching solenoid 141, and selects A as the coin dispensing tube.
Select tube.

Also, the output of the AND circuit 179 is the output of the AND circuit 18
5. Flip-flop 1 via OR circuit 137
38, the coin is set, and the coin dispensing motor _M01 is rotated to dispense the 10 yen coin from the A tube in the same manner as the dispensing of the 10 yen coin in the refund operation.

Next, the count value of the 10 yen coin storage counter 32
Suppose R _AN is 0. Here, R _AN =0 does not mean that the main tube (A tube) of the 10 yen coin is completely empty. A state of R _AN =0 indicates a state where at least an amount equivalent to the maximum change of 10 yen, for example, 9 or more coins remains in the A tube.

When R _AN =0, the output of flip-flop 197 and the output of comparator circuit 190 (R _AN =0),
Flip-flop 20 for holding D tube switching signal
The AND condition of the AND circuit 214 to which the inverted signal (signal indicating that the DD tube is not disconnected) is applied is satisfied, and the output "1" is applied to the AND circuit 181.

Other input terminals of the AND circuit 181 include a terminal
A signal DBT from _T9 indicating that the C tube is for 50 yen coins is applied via the OR circuit 215.

Therefore, the AND condition of the AND circuit 181 is satisfied, and a signal "1" is applied to the AND circuit 216.

Since the output of the AND circuit 179 is applied to the AND circuit 216, when the timer 121 expires, the AND circuit 216 is opened and a signal "1" is applied to the flip-flop 217 to set it.

The set output of the flip-flop 217 is applied to the coin dispensing motor _M02 to start rotating the motor _M02 .

The coin dispensing motor _M02 dispenses 10 yen coins from the 10 yen coin auxiliary tube (D tube).

Due to the rotation of coin dispensing motor M ₀₂ , the motor
When the carrier switch 195 for _M02 is turned on and off, this fall is detected by the fall detection circuit 218, and the detection signal "1" is sent to the reset terminal of the flip-flop 217 via the OR circuit 145, the AND circuit 146, and the OR circuit 219. In addition, this is reset and motor _M02 is stopped.

As a result of the above operation, one 10 yen coin is dispensed, and when this dispensing is detected by the dispensed coin detection switch 150, a signal "1" is sent to the coin dispensing confirmation signal holding flip-flop 1 via the AND circuit 151.
52 and set it.

The rise of the set output of the flip-flop 152 is detected by the rise detection circuit 153, and this detection output "1" is applied to the 10 yen coin counter subtraction command circuit 187 via the AND circuits 154 and 186, and 10 is subtracted from the count value R _A. and simultaneously add the output of the AND circuit 186 to the 10 yen coin storage amount counter subtraction command circuit 191 via the AND circuit 189.
Subtract 1 from the count value R _AN .

By the way, in this operation of dispensing 10 yen coins from the D tube, even though the coin dispensing motor _M02 rotates, the dispensing coin detection switch 15
When the coin dispensing is not confirmed by 0 and the flip-flop 165 for holding the lock signal is not set, the output of the AND circuit 193, the output of the OR circuit 208 and the coin dispensing tube are connected to D.
The AND condition of the AND circuit 220 to which the signal indicating that the tube is selected (the output signal of the AND circuit 216) is satisfied, and the signal "1" is sent to the counter 141 via the OR circuit 204.
In addition to the 0 reset terminal, the contents of the counter 1410 are cleared, and at the same time, this signal is sent to the OR circuit 206.
via the reset terminal of flip-flop 197 to reset it.

Since the AND condition of the AND circuit 214 is no longer satisfied due to the reset of the flip-flop 197, the AND condition of the AND circuit 180 is satisfied when the AND condition of the AND circuit 179 is satisfied, and thereby the flip-flop 184 is set and the A-tube switching solenoid 141 is turned on. The A tube is energized and selected as the coin dispensing tube, and the remaining change is dispensed from the A tube by the rotation of the coin dispensing motor _M01 in the same manner as described above, R _A =
When the value becomes 0, the payout of change ends.

In the above explanation, we have explained the case where the C-tube is used as an auxiliary tube for 50 yen coins, but in a vending machine that sells products with a price that requires a large number of 10-yen coins as change, the C-tube can be used as a 10-yen coin auxiliary tube. Can be switched to an auxiliary tube for coins. In this case, the signal DBT applied to the terminal _T9 becomes "0".

Therefore, when dispensing 50 yen coins, R _BN ≠
If it is 0, the AND condition of the AND circuit 135 is established, the flip-flop 138 is set via the OR circuit 137, the coin dispensing motor _M01 is rotated, and the 50 yen coin is dispensed from the B tube in the same manner as above. However, if R _BN = 0, the AND condition of the AND circuit 213 is satisfied and the signal “1” is sent via the OR circuit 174 to the 50 yen → 10 yen transfer command circuit 17.
In addition to 5, transfer R _B to R _A.

In addition, when dispensing 10 yen coins, if R _AN ≠ 0, the output "1" of the AND circuit 179 is applied to the flip-flop 184 via the AND circuit 180, and this is set to turn on the A tube switching solenoid 141. When activated, the 10 yen coin is dispensed from the A-tube. Assuming that R _AN =0 and the flip-flop 19 for holding the C tube blank signal is not set, the output of the flip-flop 197, the output of the comparator circuit 190 (R _AN =0), and the inverted signal DBT from the terminal _T9 . The AND condition of the AND circuit 221 to which the signal is applied is satisfied, and the signal "1" is applied to the AND circuit 182.

The output of the C-tube blank signal holding flip-flop 19 is applied to the other input terminal of the AND circuit 182 via an OR circuit 222. Therefore, at this time, the AND condition of the AND circuit 182 is satisfied, and a signal "1" is applied to the AND circuit 223.

The AND circuit 223 includes the AND circuit 18
1 and the AND circuit 179
Since the output of is added, the AND circuit 179
When the AND condition is satisfied, the output of the AND circuit 223 becomes "1", and this signal "1" is passed to the OR circuit 1
83 to the flip-flop 199, and set this to the C-tube switching solenoid 14.
2 and switch the dispensing tube to the C tube.

As a result, when the coin dispensing motor M ₀₁ rotates, a 10 yen coin is dispensed from the C tube, but even when the motor M ₀₁ rotates, the dispensing of the coin is not confirmed by the coin detection switch 150 and a coin dispensing confirmation signal is sent. Assume that the holding flip-flop 152 is not set.

At this time, the output of the flip-flop 165 for holding the lock signal via the OR circuit 208, the output of the AND circuit 193, and the AND circuit 224 to which the signal indicating that the C tube is selected as the payout tube are added. When the condition is met, a signal "1" is applied to the reset terminal of the counter 1410 via the OR circuit 204 to reset it, and this signal "1" is applied to the OR circuit 206.
In addition to the reset terminal of flip-flop 197, it is reset via the reset terminal of flip-flop 197.

When the flip-flop 197 is reset, the AND condition of the AND circuit 221 no longer holds true.
The output of the AND circuit 223 becomes "0", but this time the AND condition of the AND circuit 180 is satisfied, a signal "1" is applied to the flip-flop 184, and this is set, and the A tube switching solenoid 141 is energized. , the remaining change will be paid out from A-tube.

Next, the C-tube blank signal holding flip-flop 19 is set, and the D-tube disconnection signal holding flip-flop 20 is reset.

At this time, AND circuit 214 and OR circuit 2
The AND condition of the AND circuit 181, in which the output of 15 is added, is satisfied, and the signal "1" is applied to the flip-flop 217 via the AND circuit 216 to set it, so the coin dispensing motor _M02 dispenses a 10 yen coin from the D tube. paid out.

In this case as well, if coin dispensing is not confirmed even though the motor _M02 has rotated, the AND circuit 220 is established, the dispensing tube is switched to the A tube as described above, and the remaining change is transferred to the A tube.
Payout from tube.

Furthermore, if the flip-flop 20 for holding the D-tube switching signal is set and the flip-flop 19 for holding the C-tube blank detection signal is reset, the AND circuit 221 and the OR circuit 222
The AND condition of the AND circuit 182 in which the output of is added is satisfied, the payout tube is switched to the C tube, and 10 yen coins are paid out from the C tube. In this case as well, when the C tube becomes empty, the AND condition of the AND circuit 224 is satisfied, the payout tube is switched to the A tube, and the remaining change is paid out from the A tube.

Note that the output of the AND circuit 255 to which the signal obtained by inverting the output of the flip-flop 20 for holding the D-tube disconnection signal and the output of the carrier switch 195 for motor M ₀₂ is added, and the output of the carrier switch 143 for motor M ₀₁ are as follows. is added to the AND circuit 227 via the OR circuit 226, and the AND circuit 22
A signal obtained by inverting the output of the lock signal holding flip-flop 165 is applied to the other input terminal of the lock signal holding flip-flop 165.

The output of this AND circuit 227 is the OR circuit 202
Since the lock signal is applied to the AND circuit 203 via the lock signal, the AND circuit 203 outputs the lock signal from the flip-flop 165 for holding the lock signal when the timer 119 ends.
When the outputs of carrier switches 143 and 195 do not fall even though they are not set,
The AND condition is established and the signal “1” is output to the OR circuit 20.
4 to the reset terminal of counter 1410 to reset it.

Also, an OR circuit 22 to which the output of the flip-flop 166 and the output of the carrier switch 143 are added.
The output of the AND circuit 229 to which the output of the flip-flop 8 and the output of the flip-flop 138 are added is the output of the AND circuit 2.
Added to 30.

The other input terminal of the AND circuit 230 is a timer 1.
The output of an AND circuit 161 indicating the end of operation 19 is added.

Therefore, at the end of the operation of the timer 119,
If the output of the carrier switch 143 is "0" or the flip-flop 166 is set, and the flip-flop 138 is not reset, the AND condition of the AND circuit 230 is satisfied, and the signal "1" is passed through the OR circuit 193. Stop circuit 19
In addition to step 4, perform a stopping operation.

Also, an OR circuit 2 to which the output of the carrier switch 195 and the output of the flip-flop 166 are added.
A signal from an AND circuit 232 to which the output of the carrier switch 143 and the output of the carrier switch 143 are added is applied to an AND circuit 233.

Since the output of the AND circuit 161 is applied to the other input terminal of the AND circuit 233 similarly to the AND circuit 230, the AND circuit 233 is connected to the timer 11.
At the end of operation 9, carrier switch 19
Is the output of flip-flop 16 “0”?
6 is set and carrier switch 1 is set.
When the output of 43 is "1", that is, when the coin dispensing motor _M01 becomes inoperable, the AND condition of the AND circuit 233 is satisfied, and the signal "1" is transferred to the flip-flop 20 for holding the D-tube disconnection signal.
In addition to the set terminal, this is set to prevent coins from being dispensed from the D tube.
