The operation of the vending machine according to the preferred application of the present invention configured as described above will be described in more detail with reference to FIGS. 3 and 4.

First, the amount of coins loaded in the change container on each of the coin mechanisms 9 is detected by the coin-specific load detection unit 130 and then input to the control unit 140 in the form of a detection signal, and the control unit 140. Detects the amount of coins loaded by the detection signal (step 210), and determines whether the detected amount of coins can be returned as change (step 220).

Next, based on the determination result of the step 220, if the amount of coins can be returned to change change, the controller 140 detects the state of input of the coins (step 230). That is, when a coin is input through the coin inlet 4, the coin is guided to the coin mechanism 9 through the coin chute 8, and the amount of the coin input by the coin mechanism 9 is sensed so that the corresponding detection signal is controlled. Since it is applied to the 140, the control unit 140 detects the input state of the coin by the detection signal.

When the coin is input in step 230, the controller 140 generates a display signal for displaying a selectable beverage according to the corresponding amount of the coin, and applies it to the display unit 160 (step 240). On the 160, the type of beverage that can be selected by the amount of coins put by the user is displayed.

At this time, when the user operates the key corresponding to the desired beverage in the beverage selection unit 110, the corresponding key signal is applied from the beverage selection unit 110 to the control unit 140 (step 250), the control unit 140 ) Generates a beverage dispensing control signal for dispensing the selected beverage and applies it to the beverage dispensing unit 150 (step 260).

As a result, the beverage dispensing unit 150 dispenses the selected beverage to the beverage dispensing opening 6 according to the beverage dispensing control signal applied from the controller 140, and the controller 140 inputs the amount of money input by the user and the selected beverage. After calculating the difference with the corresponding amount of the drink, that is, change (step 270-a), and displaying the type of change coin that can be returned according to the loading amount of the coin according to the coin mechanism 9 detected in step 210. A display signal is generated and applied to the display unit 160 (step 270-b).

Thus, the type of coins that can be returned is displayed on the display unit 160, and when the user manipulates a key corresponding to the change coin to be returned by the change coin selector 120, a corresponding key signal is input to the controller 140. (Step 280), the control unit 140 outputs the change coin output signal for discharging the change coin selected by the user according to the key signal applied from the change coin selector 120 by the change change calculated in step 270. Is generated and applied to the coin mechanism 9 (step 290).

Thereafter, the coin mechanism 9 discharges the coin from the change container to the coin returning hole 7 according to the change coin calculated in the step 270 according to the change change signal.

On the other hand, if the amount of coins is insufficient to return the change in step 220, the control unit 140 generates a display signal for indicating that there is no change coin and apply to the display unit 160 (step 300). ), The display unit 160 indicates that there is no change coin by a letter or numeric signal according to the display signal.

As described above, the control unit 140 detects the loading amount of the change coin loaded in each change container of the coin mechanism 9 according to the detection signal applied from the coin-loading load detection unit 130, and then the coin input hole (Fig. The difference between the amount of coins put into the coin mechanism 9 and the corresponding amount of the beverage selected by the user through the 1) 4) is calculated, and the type of changeable coins that can be returned to the display unit 160 is displayed. If you select the change coin by operating the corresponding key of the change coin selector 120, the coin change corresponding to the calculated change coin is to be discharged from the coin mechanism (9) to the coin return hole (6).
