Description

Sales circuit of vending machine

1 is a sales circuit diagram of a vending machine according to the present invention.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine for selling coffee, tickets, and the like, and more particularly to a sales circuit of a vending machine capable of selling a target product even when there is no change.

In general, a vending machine is known as an unmanned vending machine that automatically provides an internal object as an outlet in response to an amount input by a purchaser. Such a vending machine provides a target object corresponding to the amount of money input and a designated button in a normal case, but when there is an abnormality, this may not be the case. That is, in the case where the power supply of the vending machine is maintained and there is no mechanical or electrical problem, the selling operation is not performed if the amount of money input is greater than the amount of the target object and there is no change. In this case, it can be seen that the selling operation can be carried out in a special case, distinguished from the case where there is no object. This is because the purchaser does not necessarily require a single object, but wants a plurality of objects.

As described above, the conventional vending machine could not be sold in the absence of change, and therefore, there was a problem in that the purchaser could not achieve this when he wanted a large number of objects.

Accordingly, an object of the present invention is to provide a sales circuit of a vending machine that can solve the above-mentioned problems.

Another object of the present invention is to provide a sales circuit of a vending machine that can perform a selling operation if the amount of money inputted when a large number of objects are desired even if there is no change.

The vending machine selling circuit of the present invention for achieving the above objects comprises: signal generating means for generating a sellable control signal by judging whether the input amount is an integer multiple of the selling amount for the target object, the sellable control signal and the general If at least one of the logic of the sales signal is a predetermined logic, characterized in that the vending machine has a sales instruction means for generating a sales signal for starting sales of the vending machine and providing it to the control unit of the vending machine. The signal generating means may include a divider for dividing the input amount by the selling price and an inverter for inverting an output signal of the divider and outputting the signal as the sellable control signal, wherein the selling instruction means is available for sale. It can be implemented as an OR gate which ORs the logic of the control signal and the general selling signal.

According to the technical idea of the present invention, even if there is no change inside, if the purchaser wants a large number of targets, the amount of money put in can be sold.

Hereinafter, a sales circuit of a vending machine according to an embodiment of the present invention will be described with reference to FIG.

Referring to FIG. 1, a sales circuit according to the present invention includes a divider 10, an inverter 20, and an OR gate 30, and a control unit 40 of the vending machine is shown together for convenience of understanding. The divider 10 receives data of the charged amount applied through the first input terminal I1 to the internal terminal A and receives data on the selling price of the target object through the second input terminal I2 to the internal terminal B. The input amount is divided by the selling amount, and a logic high or low is output to the output terminal Y depending on whether there is a remainder. Here, normally, if there is a remainder, it is high, and if not, it is output as low. The logic of the output terminal Y is inverted by the inverter 20 and output as the sellable control signal. OR gate 30 acts as the selling instruction means and logically combines the sellable control signal which is the output of the inverter 20 and the general selling signal from the general input terminal T1. This is to generate a sale signal for starting the sale of the vending machine and provide the control signal to the controller 40 of the vending machine when at least one of the logic of the sellable control signal and the general sale signal is a preset logic.

To explain one embodiment of the operation according to the above configuration, assuming that the circuit of FIG. 1 is a ticket machine for selling rail tickets, for example, a ticket is set at 250 won and the buyer inputs a 500 won coin. Let's say In this case, of course, if there is no change in the inside of the vending machine, a display of no change and conventionally stops the sale. However, in the present invention, the control unit 40 controls the guidance that there is no change, but can be sold when purchasing a plurality of sheets through a separate circuit not shown. In this case, when the purchaser presses a selection button for purchasing two sheets, the selling circuit of FIG. 1 operates very preferably. That is, the divider 10 receives and divides the data of the terminals A and B and outputs a logic low when there is no remainder. Thus, the inverter 20 inverts it high and provides the input to one side of the OR gate 30. The OR gate 30 provides the high signal, providing a logic high on the line L1 regardless of whether the logic of the terminal T1 is low. Therefore, the controller 40 checks the logic on the line and outputs a driving command through the line L2 informing the user to perform a preset selling operation according to the program. The vending machine thereby provides two tickets for the outlet. Accordingly, there is an advantage that the buyer can purchase a round-trip ticket in advance, the sales side has the effect of promoting the sale.

According to the present invention as described above, even if there is no change in the inside of the vending machine, if the purchaser wants a large number of objects, the amount of money put into the vending machine can perform the selling operation.
