Description

[Detailed Description of the Invention] This invention relates to a bend test device for a vending machine, and particularly to a device that can display a set price during a bend test.

Nowadays, the number of price settings in the changer section of vending machines tends to gradually increase, and as a result, it has become a difficult task to set prices on the price setting switch corresponding to each product selection switch. Mistakes are also more likely to occur. especially,
The price setting switch installed in the changer is extremely small and is set using a BCD code using a pin, making it easy for errors to occur.

By the way, in the conventional bend test, the vending machine is made ready for selling by pressing the bend test switch, and then the product selection switch is pressed.
This was to confirm that the vending machine was working properly. However, even if the operation could be confirmed, since coins of a predetermined amount were not actually inserted, it was not possible to confirm whether the product selling price was set correctly.

This idea was made in view of the above points,
The purpose of the present invention is to provide a bend test device capable of confirming whether a product selling price is set correctly during a bend test.

An embodiment of this invention will be described below with reference to the accompanying drawings.

The control device of a vending machine is generally divided into a changer section and a bender section, but the bend test price display control circuit 10, which is the main part of this invention, is provided on the changer section side. This price display control circuit 10 is supplied with outputs from product selection switches SW ₁ to _{SW 4} provided on the vendor side. Also,
The output of the price display control circuit 10 is supplied to a display 12 via a decoder 11. This decoder 11
The display device 12 is used to display the input amount or the remaining amount counted and stored in the main counter 13 during the sales operation, and in the present invention, these existing display devices are shared. The main counter 13 is a well-known device that adds and counts the amount of coins inserted and subtracts and counts the selling price or the amount of change paid out.

The bend test price display control circuit 10 includes a bend test switch 14, reset priority flip-flops 15 to 19, and each product selection switch _SW1.
It includes AND gates 20-23 for gating the product pricing signals _SP1 - _SP4 corresponding to _SW4 . When the bend test switch 14 is pressed, the flip-flop 15 is set and the line 24
"1" is applied to one input of each AND gate 20 to 23 via. flipflop 16~1
Reference numeral 9 is provided corresponding to each of the product selection switches SW ₁ to _{SW 4} , and the outputs of the corresponding switches SW ₁ to SW ₄ are supplied to the set input S, respectively. In addition, the outputs of the remaining three switches (three out of SW ₁ to _{SW 4} ) that do not correspond to each flip-flop 16 to 19 are connected to the OR circuit 25.
.about.28 respectively. Therefore, a certain
When one switch (SW ₁ to SW ₄ ) is pressed, the corresponding flip-flop (16 to SW 4) is pressed.
Only one of 19) is set, and the rest (16~
The remaining three (19) are definitely reset. The output of each flip-flop 16-19 is supplied to a corresponding AND gate 20-23, respectively. Product price setting signals SP ₁ -SP ₄ are applied to the remaining inputs of the three-input type AND gates 20 - 23 . each signal
SP ₁ to _{SP 4} are serialized product price settings set in, for example, a BCD code format by a price setting switch (not shown).

The output of AND gates 20 to 23 is an OR circuit 29
The signal is output from the circuit 10 via the circuit 10 and applied to the decoder 11. Therefore, the only product pricing signal (one of SP ₁ to SP ₄ ) selected by the AND gates 20 to 23 is supplied to the decoder 11, which parallelizes the signal and decodes it into a decimal number. It is displayed on the display 12.

The reset input R of the flip-flop 15 is connected to a signal VE (for example, the main counter 1) indicating that the vending machine is in a vending operation other than a bend test.
A signal indicating that the number 3 is in the counting operation or in the change dispensing operation is supplied. This is to reset the flip-flop 15 and disable the AND gates 20-23 during the selling operation, so that a bend test cannot be performed and the display 12 can be used for the main counter 13. .

Next, the test procedure will be explained.

The route manager of the vending machine operates the price setting switch for each product in advance to set the desired price. Next, press the bend test switch 14 to enter the test state. Next, for example, the switch SW ₁ is pressed, the price setting signal SP ₁ is selected, and the price is displayed on the display 12. The route man looks at the display on the display 12 and confirms whether the price setting is correct. Next, press another switch SW ₂ , the previous switch
Flip-flop 16 corresponding to SW ₁ is reset and pricing signal SP ₂ is selected. Thereafter, in the same way, the user presses the product selection switches SW ₃ and SW ₄ one after another and confirms the price setting by looking at the display on the display 12.

Although not shown in the figure, it goes without saying that a normal bend test circuit, ie, a circuit for checking the operation of the vending machine, is also provided.

As explained above, this invention has the excellent effect of making it possible to confirm the sales price of a product during a bend test.

Claims (1)

[Scope of Claim for Utility Model Registration] A vending machine is set to a vending state by operating a bend test switch, and in this state, the product is selected by operating any one of a plurality of product vending switches. In a bend test device that performs a bend test to determine whether or not a product corresponding to a switch has been discharged, a bend test device is provided corresponding to the product selection switch, and stores the output of the corresponding product selection switch, and stores the output of the product selection switch. a storage means that is erased by the output of any other uncorresponding product selection switch; and a storage means provided corresponding to the storage means to indicate that there is a memory in the corresponding storage means and that the bend test switch is operated. Means for generating a signal indicating a product setting price corresponding to the operated product selection switch, on the condition that signals indicating the same are generated, and selection of the operated product in response to the output of the generating means. A bend test device comprising display means for displaying a product sales price corresponding to a switch, and in addition to the bend test, a product setting price corresponding to each product selection switch is confirmed.
