A selector button 73B is provided to allow the consumer to select the flavor and type of the mixed beverage.

A prior art attempt to convert the aforementioned system of FIG. 2 into a coin-operated cup vending machine was made by attaching a coin recognition module to a countertop dispenser. This system is shown generally in FIG. More than the specified amount of syrup that could occur in the aforementioned system
An interface control circuit 'rC is provided to eliminate the possibility that - is distributed. To solve this problem, each syrup dispensing branch of the system is equipped with an inverter ESW coupled to a control fan module TC in a tie and control module TC. In addition, syrup pumps P1, P2.P

The closure of valve SV is controlled by timer TC and limits the duration of the sales cycle. That is, a timer at TC generates a signal that closes valve SV at the end of a predetermined period of time.

In this system of FIG. 3, the sales cycle proceeds in the following manner. When the consumer inserts the appropriate coin for a cup of beverage into the coin recognition device CV and the credit L7 is confirmed by the coin recognition device CV, an electrical signal is generated by the interface control circuit T Open the two-way solenoid tSV in all the flows of pump PL-P4 and direct the propellant fluid to each gas propellant line GPI to GP4 containing the manually operable gas selector jrGSl-GS4. provide.

The coin handling system of Figure 3 has several drawbacks. One drawback is that each dregs propellant conduit GPI ~
In each of the GF4, the arrangement of the gas selector valves jGs1-GS4, which can be manually operated, is similar to the selector button 5BI.
- It is necessary to hold one of the 5B4s down throughout the dispensing cycle to allow continuous flow of syrup. This, of course, creates problems for the consumer, one who is not familiar with the machine. For example, a user can turn the selector button on and off with his finger, and each time, the timer in the TC determines that the cycle is complete and the three-way solenoid valve SV closes. The syrup flow starts and starts. This may unnecessarily lengthen the dispensing cycle or result in dispensing less than a full cup of beverage, and the consumer may remove the cup before the sales cycle is complete. Furthermore, all four gas lines G5l-G54 of the pumps of each of the pumps in the system of FIG. are enabled or pressurized at the same time through The distribution side is 11, which is obviously better than 91.

FIGS. 4 and 5, in combination, illustrate an improved syrup selection and dispensing system to an unreleased product 1111. As in the previously described coin-operated system J of FIG.
There are two separate pumps P1 to P4 for pumps J'; The uninvented system will be described assuming that a mixed beverage is to be dispensed and poured into a cup at a cup station behind door D in the machine of FIG.
