Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a control circuit for a vending machine, and in particular, to a control circuit for a vending machine that provides a discount when a plurality of products are sold consecutively within a range of input amounts. This is what I did.

[Prior art and its problems]

There are various types of vending machines that have this type of discount function, but the content of the products sold in the vending machine (
There are various types of products, sales prices, promotions, etc.), and changing discounts according to these factors has not always been sufficient to promote sales.

[Object of the Invention] In view of the above-mentioned points, it is an object of the present invention to provide a control device for a vending machine that is capable of changing the discount details according to the contents of the products to be sold.

[Summary of the Invention] The present invention makes it possible to set the number of sold items to be discounted (discounted number of items) and the discount amount, and resets the number of sold items that are counted each time the remaining amount of the amount calculating circuit becomes zero. By setting the set discount amount to be discounted when sales are made consecutively to reach the set discount quantity, the discount details (quantity and amount) can be changed depending on the content of the product being sold. This is an attempt to promote sales.

[Embodiments of the invention]

The present invention will be described in detail below with reference to the drawings.

In the description of the drawings, a signal at a high potential level will be referred to as an H signal, and a signal at a low potential level will be referred to as an L signal.

Since the framed circuits for each function shown in the drawings are the same as those with known specifications, the internal circuit configurations are omitted, and clock pulse generation circuits that are not shown in the prescribed framed circuits are It is assumed that the same clock pulse is supplied from both. In the standby state, the input amount is counted,
A date signal is output from the output terminal OUTI of the coin mech control circuit 1, which includes an amount calculation circuit for performing comparisons, a sellability determining circuit, and the like.

This H signal is output when the coin mech control circuit is not performing an operation such as addition. In addition, the sales number counting circuit 8
As will be described later, an L signal is sent from the output terminal OUT6 when the number of sold items has not reached the set value. This L signal is converted to an H signal via the inverter 17, so the two inputs to the AND circuit 14 both become H signals, the CREM circuit 3 is activated, the gate of the coin slot (not shown) is opened, and the coin is inputted. It is set to be ready for reception. When a coin is inserted, the authenticity of the coin is checked by the coin input detection circuit 2, and a pulse corresponding to the amount of the coin, for example, a clock pulse, is used to output "100" if the coin is 10 yen, and "100" if the coin is 50 yen. “101 Bi,
For 100 yen, enter 1-2- such as “0101”
It is converted into a code signal weighted 4-8, and this code signal is sent to the input terminal inl of the coin mech control circuit 1 via the OR circuit 13.

The coinmech control circuit 1 houses a deposited amount counter 6 configured as an addition/subtraction counter that adds or subtracts the deposited amount, and a price setting circuit 23. For convenience of explanation, these deposited amounts are shown below. The counter 6 and price setting circuit 23 are shown separated from the coinmech control circuit 1. When a code signal converted according to the amount of coin as described above is input from the coin input detection circuit 2 to the coin pick control circuit 1, the code signal sent sequentially in response to the insertion of a coin indicates the amount of money inserted. The counter 6 adds and stores the input amount, and the price setting circuit 23 compares the input price with the set sales price of the product to determine whether or not it can be sold.

When the input amount is equal to or more than the selling price of the product, an H signal as a sales permission signal is output from terminal OUT8.
Send from For the AND circuit 22 as a product sending circuit that receives the H signal from the output terminal OUT8,
Furthermore, the H signal via the inverter 17 and the H signal output from the product overload detection circuit 20 when there is a product are input. Therefore, when the product selection switch 19 is selected and the H signal is applied to the AND circuit 22, the AND circuit 2
2 is satisfied, the H signal is given to the product delivery mechanism 21 as the product delivery signal, and the product can be sold. When a product is sold, a sales confirmation signal (a signal generated each time a product is sent) is output from the sales confirmation signal sending circuit 4, and by applying this to the input terminal in2 of the coin mech control circuit 1, the input amount is counted. Switch to subtraction in evening 6 and calculate the remaining amount by subtracting the set price of the sold product from the total input amount.

This operation is repeated, and when the input amount is equal to or higher than the set price of the product, the sales permission signal continues to be sent from the output terminal OUT8. On the other hand, since a sales confirmation signal is also sent to the input terminal in8 of the sales number counting circuit 8, the number of sales is counted and stored here. The sales quantity counting circuit 8 receives a signal from the discount quantity setting circuit 9 at its input terminal i, in which the number of consecutive sales units to be discounted is set in advance.
This is received by n12 and compared with the counted value of the signal applied to the input terminal in8, and if this counted value reaches the discount number, an H signal is sent out from the output terminal OUT6.

In other words, the signal at the output terminal OUT6 of the sales quantity counting circuit 8 is low in the standby state and in continuous sales below the discounted quantity.
However, when the number of consecutive sales reaches the discount number, an H signal is issued as a discount command signal. This H
When the signal becomes L, the output side of the inverter 17 becomes an L signal, so the AND circuit 14 fails and the CREM circuit 3 operates, blocking the coin slot and closing the AND circuit 22.
, 16, thereby disabling product sales, refunds, and settlements. Now, when the signal at the output terminal OUT6 of the sales quantity counting circuit 8 becomes an H signal, the product sales, refunds, and settlements are inactive and additions, subtractions, etc. are not being performed. A signal is generated, the AND circuit 15 operates, and its output signal is sent to the input terminal inlo of the coin input pulse conversion circuit 11.

Input terminal inl1 of this coin input pulse conversion circuit 11
includes a discount amount setting circuit 10 in which a discount amount is set in advance.
Since a signal corresponding to the discount amount is added, only when the input terminal inlo' this day signal is input, the code signal corresponding to the discount amount is detected, similar to the code signal from the coin input detection circuit 2 described above. It is sent out from the output terminal OUT7. The output signal is led to the OR circuit 13 and, like the code signal from the coin input detection circuit 2, is applied to the input terminal inl of the coin mech control circuit 1. At this time, since the H signal from the sales confirmation signal sending circuit 4 is not applied to the input terminal in2, the input amount counter 6 in the addition state in the coin mech control circuit 1 adds and stores the amount.
This means that the amount has been increased by the amount of the discount, and as a result, it has been discounted. Sales quantity counting circuit 8
While the H signal is being sent from the output terminal OUT6 of the inverter 7, the output side of the inverter 7 becomes an L signal, so the outputs of the fund circuits 16 and 18 are locked while the discount amount is being added, and therefore the refund/settlement signal is not sent during that time. Even if the button of circuit 5 is pressed, it becomes invalid.

In addition, when the number of discounted items is reached, the remaining amount of the input amount becomes 0 yen by chance, and the output signal of the output terminal OUT4 of the input amount 0 yen detection circuit 7 changes to an H signal due to the output signal of the output terminal OUT3 of the input amount counter 6. Even when , the output signal of the inverter 7 is an L signal and the condition of the AND circuit 18 is not satisfied, so the AND circuit 18 does not output an H signal.

Therefore, the L signal is applied to the input terminal jn6 of the reset signal generation circuit 12, and the input terminal i of the sales quantity counting circuit 8 is applied.
No reset signal is applied to n7, and this circuit 8
cannot be reset. The signal at the output terminal OUTI of the coin-pick control circuit 1 is used for the operation of the OREM circuit 3, but when this circuit 1 is performing calculations such as addition and subtraction, the output from the output terminal OUTI becomes an L signal, and only when in the standby state. It becomes an H signal.

Therefore, the role of the AND circuit 15 is to cause the coin mech control circuit 1 to perform a discount operation after the operation is completed. When the operation of the coin input pulse conversion circuit 11 is completed,
An H signal is generated from the output terminal OUT9, and when this signal is received by the reset signal generation circuit 12, a reset signal is generated from the output terminal OUT5 of the same circuit 12, and the sales quantity counting circuit 8 is reset. Finish the operation.

As a result, the output of the output terminal OUT6 of the circuit 8 is returned to the L signal, prompting the CREM circuit 3 to operate again and opening the coin slot. Further, the conditions for the sales number counting circuit 8 to be reset by the reset signal generation circuit 12 are when the input amount becomes 0 yen before reaching the discount number, and when the refund or settlement input becomes an H signal. be.

As described above, the amount calculation circuit configured using the input amount counter 6 in the coin mech control circuit 1 calculates the input amount based on the signal from the coin input detection circuit 2, and the coin mech control circuit 1 determines whether the coin can be sold. The circuit compares this input amount with the set price set in the price setting circuit 23 to determine whether or not the sale is possible, and if the input amount is greater than or equal to the set price, a sales permission signal is sent to the AND circuit 22 as a product sending circuit. Output.

When the product selection switch 19 is operated by the customer while this sales permission signal is being output, a product delivery signal is output from the AND circuit 22 to the product delivery mechanism 21, and the product is delivered. At this time, a sales confirmation signal is output from the sales confirmation signal sending circuit 4, and the set price of the sent product is subtracted by the above-mentioned amount calculating circuit to calculate the remaining amount, and the sold quantity counting circuit 8 sells the product. The number of pieces is counted. The same operation is repeated for the remaining amount, and when the number of sold items reaches the discount number set in the discount amount setting circuit 9, a discount command signal is output and the discount amount set in the discount amount setting circuit 1 is set. The conversion circuit 11 outputs the amount to the amount calculation circuit described above, and the amount calculation circuit adds it to the remaining amount. After outputting the discount amount, the conversion circuit 11 outputs a signal to the reset signal generation circuit 12, and the sales quantity counting circuit 8 is reset. Therefore, at this time, the customer selects product selection switch 1.
9, you can purchase more products with the discount amount added to the remaining amount, or you can use the refund/settlement signal circuit 5.
You can also refund this amount as change by operating the button. Further, the detection circuit 7 detects whether the amount in the amount calculation circuit (inserted amount counter 6) is zero, and based on the output of this detection circuit 7, the reset signal generation circuit 12 determines whether the amount in the amount calculation circuit is zero. An IJ set signal for resetting the sales number counting circuit 8 is output when the number becomes zero again after it becomes zero due to the insertion of coins.

Therefore, if the remaining amount becomes zero before the number of sold items reaches the discounted number, the number of sold items at that time will be cleared, so if sales are performed continuously up to the discounted number before the remaining amount reaches zero. Discounts will only be given to [Effects of the Invention] According to the present invention as described above, since the discount quantity setting circuit and the discount amount setting circuit are provided, the content of the product (product type, product type,
It is now possible to change the discount details (quantity and amount) according to the sales price, sales line, etc., and the number of sold items counted for discounting is reset every time the remaining amount of the amount calculation circuit becomes zero. , When the number of sold items reaches the set discounted number, the set discount amount is output to the amount calculation circuit, so sales can be continued up to the discounted number before the remaining amount reaches zero. Only occasionally, the discounted amount is paid out as change in the amount calculation circuit, added to the remaining amount, and used for the sale of the next product, thereby ensuring a discount and greatly promoting sales.
