Next, the operation of the vending machine control device having the above configuration will be explained.

First, it is assumed that the raw material tanks 12a to 12d are stocked with a predetermined amount of each of the raw materials shown in the above configuration. At this time, mold to be carried out from each raw material tank 12a to 12d when one sale is executed, that is, the operating time of the motors 13a to 13d is set using the raw material setting switches 3a to 30 and written in the RAM 8, and each The increase/decrease in raw material is set by switching the switch 30 to 3S. An example of the settings is shown in FIG. In this figure 3, the amount of sugar is set to increase, and 30 is set to 10%.
The rate of increase with 3p on the 30% side is 4 of the standard sugar export amount.
It is set to be exported with an increase of 0%.

Now, when a customer inserts, for example, 100 yen into a vending machine, the coin detection mechanism 2 sends a signal equivalent to 100 yen to the CPU 1.
send to CPtJl determines the products that can be sold based on this input amount. Next, the customer turns on one of the product selection switches 48 to 4n corresponding to a sales product such as hot coffee, and also turns on one of the cream/sugar increase/decrease instruction switches 20a and 20b. cp
The ui reads which of the switches 4a to 40 are turned on and detects that an instruction has been given to sell any one of the products, such as hot coffee. If hot coffee is selected, the amount of coffee ingredients, amount of sugar, and cream image are read out from RAM 8, and the time corresponding to each ingredient is calculated, and if the increase/decrease instruction switch is pressed,
The increase/decrease rate is determined by checking the state of the increase/decrease setting switches 30 to 3S, and the time is calculated by adding or subtracting the time corresponding to a predetermined increase/decrease rate from the time corresponding to each raw material type calculated above. , the relays 58 to 56 corresponding to the respective raw materials are turned on for the calculated time, and predetermined ones of the motors 13a to 136 are driven to dispense predetermined amounts of coffee raw materials, cream, and sugar. It is discharged from predetermined tanks 12a to 12d. Similarly, the relay 6a is turned on, the electromagnetic valve 19 for draining is opened, and a predetermined amount of hot water is discharged from the water tank 10 to the nozzle 17. Note that, for example, when the temperature of the water storage tank 10 falls below a predetermined temperature, the heater 11 is energized and heats the water in the water storage 1io. When the water temperature of this water storage 110 rises to a predetermined temperature, power supply to the heater 11 is stopped. Further, when the water in the water tank 10 reaches a predetermined amount or more, the water intake valve 18 opens, and the water in the water tank 10 is opened.
Water is supplied to the tank, and when the amount exceeds a predetermined amount, the water intake valve 18 is closed.
