[Structure of the idea]

(Means for Solving the Problems) The product pricing device for a vending machine of the present invention displays samples of changeable products to be sold, and sells products based on a sales request based on a purchase operation. The machine is provided with a switch means for selectively displaying an arbitrary number of multiple digits in a position corresponding to the sample of the product and outputting price data corresponding to the number, and a switch means for switching the price display of the product for sale. The product price is set based on the output of the price data of the changeover switch means.

(Function) The present invention selectively displays an arbitrary number using a changeover switch provided at a position corresponding to a product sample, and outputs price data corresponding to the displayed price of the changeover switch. Based on this, the price of the product for sale is set.

(Embodiment) Hereinafter, the configuration of an embodiment of the present invention will be described with reference to the drawings.

First, FIGS. 1 and 2 show the external appearance of a vending machine 1. A product display shelf 2 is installed inside the vending machine 1, and on the front side, for example, A, B, etc.
Four types of products 3a, 3b, 3c, and 3d, C and D, and corresponding product samples 4a, 4b, 4c, and 4d are placed. Then, price display sections 5a, 5b, 5c, and 5d and purchase availability display devices 7 correspond to the positions.
Display lamps 8a, 8b, 8c, and 8d are provided. Additionally, inside the vending machine 1, there are product dispensing devices 10a, 10b, 1 for dispensing products one by one.
0c, 10d, a change dispensing device 11 that dispenses change when necessary during sales operations and a sales control device 12 are installed, and a product selection device 1 is installed on the front door that can be opened and closed freely.
5 selection switches 13a, 13b, 13c, 13
d and a coin sorting and counting device 14 are provided.

Thus, the price display section 5 is disposed at a position corresponding to the product sample 4 so as to be freely changeable.

Furthermore, as illustrated in FIGS. 3 and 4, the price display section 5 has a function as a changeover switch means, and is constituted by, for example, a digital switch. The digital switch as the changeover switch means 5 is formed of a rotating display for each digit, and selectively displays several digits, for example, three digits, with the rotating display. As the rotary display body rotates, it outputs price data corresponding to the displayed numbers, which are encoded with, for example, a BCD code, when a switch contacts a contact point or the like. The one in Figure 3 outputs price data corresponding to the displayed price of 150 yen. Furthermore, the fourth
In the example shown in the figure, no number is written on the number display surface of the most significant digit, and no number is displayed. This is because when a price of 80 yen is displayed, displaying ``080'' would easily cause a misunderstanding among buyers, so ``80'' is displayed to prevent misunderstandings.

In addition, here is an overview of the operation of the vending machine 1 in Section 5.
This will be explained with reference to the figures.

When the purchaser inserts a coin, the inserted coin detector 16 of the coin sorting and counting device 14 detects the coin and generates a detection pulse signal _S1 . Then, a presettable up-down counter 17 as counting storage means counts and stores the detected pulse signal S ₁ and sends it to the sales control device 12 . Here, the purchaser selects the selection switches 13a, 13 of the product selection device 15.
b, 13c, and 13d to select and specify one or more products, the sales control device 12 performs arithmetic and comparison operation based on the selection signal _S8 , and selects the corresponding product dispensing device 10a within the range of the input amount value. ,10b,10
c, 10d. The products selected in this way are sequentially dispensed.

In this case, the changeover switch means 5a, 5
b, 5c, 5d are price signals S ₄ (S ₄ a, S ₄ b, S ₄ c,
S ₄ d) is output.

Furthermore, when the product is available for purchase, the purchase availability display device 7 displays a group of products that can be sold using lamps 8a, 8b, 8c, 8 based on the purchase availability signal _S6.
The purchaser is notified by the light emitted by d. The product dispensing device 10 dispenses the selected products 3a, 3b, 3c, and 3d in response to the dispensing signal _S7 based on the purchaser's product selection, and the stored contents of the up-down counter 17 change to the dispensed product. will be deducted by the amount equivalent to the price. On the other hand, when the purchaser requests payment, the change dispensing device 11 dispenses change until the stored content of the up-down counter 17 becomes zero.

Now, the above device can be achieved with a circuit configuration as shown in FIG. Note that this circuit example, like the vending machine 1, sells four products 3a, 3b, 3c, 3.
It is configured to target d. Detection pulse signal S ₁
becomes the up input of the up down counter 17. The up-down counter 17 counts and stores the amount, and the sales control device 12
A count signal S ₂ is output to the arithmetic circuit 18 of.

Here, the arithmetic circuit 18 receives a timing signal obtained from, for example, a program control section (not shown) to connect and control these operation circuits at organic timing, and performs numerical calculations and logic in the arithmetic circuit 18. Various calculation processes are performed based on an operation command signal _S15 specifying the type of calculation. The arithmetic circuit 18 also includes a product sample 4.
Changeover switch means 5a, 5b, 5c, and 5d are connected to the terminals 5a, 4b, 4c, and 4d, respectively, for displaying the prices of the products for sale and outputting price data. These changeover switch means 5a, 5
b, 5c, and 5d each display 3 digits, but the 1's digit is always displayed as 0, so there are 4 bus lines that display the 10's digit and 100's digit. It is connected by a total of 8 bus lines, 4 bus lines for displaying the digits.
Note that this detailed configuration will be omitted.

When the purchaser inserts money, the contents of the up-down counter 17 are inputted to the arithmetic circuit 18 as an 8-bit parallel count signal _S2 . At the same time, other input terminals of the arithmetic circuit 18 are connected to the changeover switch means 5a, 5b, 5 set corresponding to the product samples 4a, 4b, 4c, 4d, respectively.
The sales price data of c and 5d is output. This sales price data is obtained through address signals S ₉ (S 9 a, S ₉ a,
_S9b , _S9c , _S9d ) are sequentially and repeatedly inputted as a price signal _S4 of 8-bit parallel data through the bus line that transmits the data.

At this time, the arithmetic circuit 18 performs a magnitude comparison operation on these two input data, outputs the result of this comparison operation as a carry signal S10, and outputs the result of this comparison operation as a carry signal _S10 , and outputs the result of this comparison operation as a carry signal _S10.

Set a, 20b, 20c, and 20d individually. Furthermore, the flip-flop circuits 20a, 2
0b, 20c, 20d are the above address signals
It is controlled in synchronization with the arithmetic circuit 18 using clock inputs S ₉ a, S ₉ b, S ₉ c, and S ₉ d, and stores products that can be sold for the above input amount.
In addition to this, this memory output is also
3a, 23b, 23c, and 23d, a purchase enable signal _S6 is generated, and the display lamps 8a...8d of the purchase enable display device 7 are selectively turned on in accordance with the memory output.

In this state, when any of the selection signals S ₈ is input by the product selection device 15, the selection signals S ₈ a, S ₈ b, S ₈ c, and S ₈ d are input to the AND gates 24a,
These selection signals S 8 a and S 8 b are compared with the stored contents of the flip-flop circuits 20 a, 20 b, 20 c, and 20 d via the flip-flop circuits ₂₄ b, 24 c, and ₂₄ d, and only when a product group with a purchaseable price is selected. ，
Flip-flop 25a corresponding to _S8c , _S8d ,
25b, 25c, and 25d are selectively set.
The flip-flops 25a, 25b, 25c,
25d is set, this flip-flop storage output is passed through an OR gate 26 to the flip-flop circuits 20a, 20b,
The memory contents of flip-flops 20c and 20d are forcibly reset, and the flip-flops 25a, 25b,
Only the stored contents of either one of 25c and 25d are temporarily stored in a latch circuit 28 via a 4-line-BCD conversion encoder 27.

The encoder 27 preferentially outputs only one of the input signals input to the four input terminals. For example, when signals are input to all input terminals, the encoder 27 prioritizes the signal at the first terminal. Outputs "1" in BCD code to the output terminal. Since the specific circuit configuration of this encoder 27 is well known, its details will be omitted.

The latch output of the latch circuit 28 is BCD-

The decoder 29 outputs a signal only to the output terminal specified by the BCD code input to the input terminal, and outputs the signal only to the first output terminal when the latch content of the latch circuit 28 is "1". .

Pulse signal as output of pulse generation circuit 22
S ₁₁ is a quaternary presettable ring counter 21
has been entered. This presettable ring counter 21 sequentially repeats and outputs the address signal S ₉ (S ₉ a, S ₉ b, S ₉ c, S ₉ d) corresponding to this count value, and the pulse generating circuit Together with 22, it constitutes a part of the program control section mentioned above.

The output signal of the OR gate 26 also serves as a preset command load signal to the ring counter 21.
_S12 , the latch signal is forcibly preset as the content of the ring counter 21, and is also input to the program control section. At this time, the arithmetic circuit 18 calculates the difference between the price signal _S4 of the changeover switch means ₅ specified by the address signal S9 output from the ring counter 21 and the count signal _S2 of the flip-flop 17. The difference is configured to be preset in the flip-flop 17.

[Effect of idea]

With this invention, the price setting can be changed at the same time by changing the price display, so there is no need for a special operation for setting the price, and furthermore, the operation can be performed at the position corresponding to the sample of the product. Because you can directly check the sample of the product,
It is possible to avoid mistaking the correspondence between the price display of a product sample and the set price when setting a price.
